OT: Hardware recommendation for graphics card?

2010-11-09 Thread Peter Alcibiades
Friend of mine asked for advice on what sort of graphics card to put in a 
machine he is putting together for his kid.  It will be i5 probably, and he 
wants to get something that will be respectable with photoshop processing.  
An i3 of mine with onboard graphics was definitely not fast enough for him.

Is i5 even enough, should he go for i7?  Its not my area of expertise.  I 
am not even sure about the relative contributions of the graphics card and 
the processor in this.

Any suggestions gratefully received.  Money is an issue, but he wants 
something that will do a decent job first and foremost.

Re: a weird thing about registration, Linux

2010-11-02 Thread Peter Alcibiades

A solution is to change owner.  After chown to my user, it runs and updates
the DGH fine.  Should not have to do this, however, and it does not solve
the problem that every account should be able to use it.  I will write to
support.

Chipp, not saying you are wrong, but how would you know?  That's the thing
that got me, and why I think Alejandro's thought of taking Windows offline
is quite sensible.  The problem with windows getting compromised is I am not
sure you necessarily know when its happened.  Most studies on anti malware
seem to show that you need more than one, and even then, you don't catch
everything.  That's why I refuse to disinfect now.  It takes forever, and
you cannot promise a proper job even then.

Yes, I get this too.  Always assumed it was a feature, just the way it works. 
How are you modifying the button graphic?  What I have done is underlay a

Re: LiveCode Linux version: graphic effects issue with the name of a push button

2010-11-01 Thread Peter Alcibiades

Zryip, another thing which is probably a Linux peculiarity, the DGH is asking
should it do an upgrade.  So you say yes, but then it can't open the file.

Its probably permissions.  The LC app is installed into /opt, and of course
the user does not have write permissions in /opt, which is what the DGH will
require.  I'll have to try it as root but that's almost certainly what it
is.  No longer recall exactly how I got it to install in the first place, it
was probably by copying into plug-ins as root.

a weird thing about registration, Linux

2010-11-01 Thread Peter Alcibiades
Has anyone else had this?

I installed and registered my 4.5 copy.  Works fine.  Now, I want to update 
the Slug's package.  It won't let me, most likely because its installed the 
app in /opt and as user I have no write privileges there.

OK, no problem, become root with the root environment, fire up LC.  Asks me 
to register!

Think, OK, maybe this is due to having the root environment, so just do su.  
Same thing.

OK, maybe this is something to do with root or root privileges, so log out, 
log on as another account.  Same thing.

This is weird.  The only point of installing in /opt as opposed to 
/home/user would be to let all accounts have access to the app in a multi 
account environment, but it seems in some way to be restricting use of the 
app to just one account?  Cannot be, surely?

I can always do it manually, download the package, delete the existing plug 
in, so that's not a problem.  The problem is if registration is restricting 
to just one account on a machine.  To be clear, no-one else uses Rev on my 
machine, but for various reasons I do use multiple accounts on the same 
machine myself and can't see why I should have to register not only by 
machine, but by account.  Anyone else getting this?

Re: a weird thing about registration, Linux

2010-11-01 Thread Peter Alcibiades

Yes, there is a .revolution folder.  And it does indeed have a cryptic
preferences text file in it.  But what I'm having trouble understanding is
that if I just acquire root permissions, by doing

  su

rather than doing

 su -

Then I retain the same home directory.  So if I then fire up rev, why does
it not find the preference files?  Is it somehow distinguishing between me
logged on with and without root privileges?  And why on earth would they
want to do that?

I can just about understand that if I do su -, which places me in the root
home directory, it might have some trouble.  But I can't understand why if,
as myself, I simply acquire root privileges, it should not find all its
files?

So, if you do su the working directory remains the same.  If you are in the
working directory without su, Rev starts.  If you are in the same working
directory after having done su, it asks you to register.

Don't get it.  The difference of course is that when it works, its
identifying the user:

 pe...@:/opt/runrev/livecode-4.5$ ./livecode.x86

as opposed to in the other case, where the prompt is just

 :/opt/runrev/livecode-4.5# ./livecode.x86

So the difference is, it is looking for the registration in a particular
user home folder?  But in that case, why install in /opt?  And why restrict
the use to one account on a multi account system?  Makes no sense, no-one
else does it, do they?

Re: [OT] Browsing the internet... It is safer from Linux?

2010-10-31 Thread Peter Alcibiades

I don't know if its safer than current versions of Windows 7 intelligently
used.  It certainly is a lot safer than earlier versions of XP, used as they
came out of the box.

One reason is that desktop linux is a small population and so not being
targeted.  

A second is when you do an install, it will obliged you to set up a root
account and a lmited user account, and your limited user account will not be
able to get at the system files.  A typical example of this is with Rev
sorry LiveCode - download the new version, try to install it, cannot.  Its
not executable, and then, it tries to install itself in /opt and you have to
be root to do that.

A third is that all payload will arrive as being unexecutable, and most of
the time marked read-only.  One of the things you always have to explain to
people when putting in Linux for them is how to change permissions, because
if not, one of the standard questions you'll get sooner or later is that
someone sent me a word processing file and I cannot edit it.  Right, its
marked read only.

So you contrast that with a situation in which for decades everyone used the
internet with administrative prilvileges, all downloaded files arrived
market executable.  Then we had the saga of Explorer and all its holes, all
the Office macros  

But the real question might be this:  if you were to set up your windows
install to always work as limited user, and if you enable privacy between
user accounts, and finally if you use a dedicated account for all financial
transactions and only use that account to go to a very small number of known
financial sites, and if you have up to date anti virus, are you any more at
risk than on Linux?

I don't know.  I hear of compromised windows installations all the time. 
Admittedly they are not Windows 7 mostly, though I heard of one of these the
other day.  They are not set up like that either, they are the standard
default set-up.  My feeling is that you probably can keep a windows
installation safe, if you work at it, and really keep your protection
software up to date.  Its just a question of what you want to spend your
time doing.  For what its worth, my own decision years ago was to do what
you are suggesting.  I do run XP in a VM for the rare occasions when its
necessary, but almost never connect to the net with it.  I decided that I
could probably keep Windows secure if I worked at it, but that life is too
short, and I the big difficulty was how I would know I had succeeded.

As to one of those risks on one of your links, guest users, well, of course
you set up a guest account on any Linux install, and if people want to use
your machine you sign them on as guest.  You don't allow the guest group to
read any of the other user files, even.  You can wipe and recreate the guest
account as often as you feel the need.  You could do this on windows too,
but no-one does.

Slax is a good live CD distribution.  It might also be worth looking at
Vector live and Zenwalk live - they will be faster than most live
distributions.  I would install Debian Stable if doing a proper desktop
installation.

Once you start using Linux routinely, you will be surprised how little you
need Windows.

Re: [OT] Browsing the internet... It is safer from Linux?

2010-10-31 Thread Peter Alcibiades

Yes, the interesting question, don't know the answer, is if you set up
windows in the same way Linux is normally set up, limited user accounts and
so on, how much more vulnerable would it be?  Those hack fests they have
every so often suggest that OSX is a dead duck almost right away, Windows
not long after, and Linux holds out longest.  But I don't know what the
starting setup is on the windows installation.

Re: [OT] Browsing the internet... It is safer from Linux?

2010-10-31 Thread Peter Alcibiades

Yes, it was the annual hackfests.  I only know two people with OSX, and
neither one has been compromised.  Whether the Unix underpinnings make OSX
more secure?  I think the hacks, but maybe others recall better, were due to
applications and privilege escalation.  

I am really not sure what to conclude about real world safety.  If you set
up all three systems the same way, with the same basic precautions, would
there be any significant differences in security?   Don't know.  I do know
that I have had two people recently, one with 7 and one with XP, ask me for
help with compromised systems.  I refuse to try to disinfect now, so one who
did not want to risk it again got Mandriva, with which he is very happy, in
fact, despite my efforts to explain, I suspect he may think its Windows 8 or
9, and the other got an OEM copy of 7, and we will be doing a reformat and
reinstall shortly. 

I do think there is a very different attitude on the part of developers. 
Linux, you see it in everything, is completely paranoid about security.  I
recall years ago when the kde dialer went to enormous lengths to take root
privileges for the shortest possible and most limited time.  Apple I think
is quite casual because of years of low risk.  Windows seems to have this
strange mixture of not taking the most basic precautions, and then layering
on all kinds of stuff to protect it.

I have never heard of a non-server compromised Linux install.

Re: revweb plug-in for linux

2010-10-28 Thread Peter Alcibiades

Its a really simple application, its for a guy that I work with.  I would
really like for him to be able to write it and keep it going himself.  I am
lately rather seriously in the mode of lessening people's dependence on me
for this stuff.  What it is, he will have a large map on a big screen.  The
map will have various links on it, and people will click on them and find
stuff of interest, footpaths and routes, local history material, zoom in to
photographs and topics.  Navigate around.

It could run locally.  Except that everything else runs on a server, so it
would be nice if it were all in one place and accessible from anywhere on
the LAN, which is why it would be nice to run it as a browser plug in.  Or
it could be web pages, except that I will have to learn how to write proper
web applications myself, and then its also already clear he is going to have
real trouble coming up to speed on that.  Whereas I am almost sure he will
be able to put something together in Rev and will enjoy learning it.  

People pick this stuff up very easily with Rev and don't even realize they
are learning programming.  I spent an hour or so with him just using a
sample map, showed him how to put buttons on, how to make them do things,
how to make them vanish behind the map but still work.  He took to it like a
duck to water, and he started immediately to think of all kinds of stuff he
could do that he had not thought of trying because he thought it would be
very complicated and difficult but now he could see that it wasn't at all. 
Play bits of sound or movie clips, for instance, or contextual menus.

Its what the sadly defunct Media was perfect for, a sort of simple
multimedia authoring.  Oh well.  I guess it either has to be local, or we
have to find something else to do it in.  Pity.

Re: [OT] Mac App Store

2010-10-23 Thread Peter Alcibiades

To most people, this has never had anything to do with OS choice or with
Apple's stock price.  It has to do with corporate conduct.  It has to do
with the following:-

1)  Do you want a society in which your access to applications and thus
increasingly to media is in the control of a few corporations who make the
platforms?  Or do you want a world in which you buy the platform, install
what you want from where you want, buy, read and watch and listen to what
you want from wherever you want?  Its the CD model versus the iTunes model.

2)  Do you as developer want to have one route to market, an App store run
by the device manufacturer, and have him able to eject your stuff instantly
on a whim?  And then let it back in again on a whim, who knows for how long?

The reason the debate now comes up with OSX has nothing to do with that OS
in particular, it is that people think, reasonably enough based on the track
record, that Apple is starting to move OSX to the iPod and iPad model.  They
don't trust it.  And they think it has serious societal implications.  Once
again, reasonably enough, given the track record.  These are the guys who
ban apps based on what you can, but do not have to, use them to download,
when the material you allegedly might download is perfectly legal in your
jurisdiction, but for some reason, the guys at Apple do not approve of it. 
They banned Matlab, for Heaven's sake!  A version of Ulysses!

Corporate control of what you can do with your computer or your ebook reader
or your tablet is a threat, probably in the West now emerging as the main
threat, to intellectual freedom.  This is not OS wars.  This is corporate
conduct wars.  The same or very similar points can be made about Amazon and
its ebook format and sales methods.

It is perfectly possible that being on the wrong side of that debate may be
very profitable for Apple and lead to rising share prices. I doubt it, I
think the probable effect of these efforts at control will be to promote
hacking and piracy.  But even were it a good route to rising profits and
stock prices, doesn't make it any righter.  And the problem is, Apple always
has been evil in this way, but it used not to matter because it was too
small for its example to matter.  Now it is getting bigger, its a real force
in society.  So you can no longer say, you don't like it don't buy it.  You
buy it or not, its influence is profound.

The Apple corded full USB is very nice.  Far better than the Cherry Strait

Re: Keyboards

2010-10-22 Thread Peter Alcibiades

I have to say, reluctantly, not being an admirer of Apple or its works, that
the latest keyboards, if that's the sort of thing you want, basically do not
have any competition.  I was using the aluminum usb full one, really came to
like it, apart from the irritating keycaps.  It is virtually silent, and my
initial worries about the angle and RSI turned out to be groundless.  

Then my partner's keyboard blew up (it was an old Apple one also), so I gave
her mine to try, and I could not get it back.  I then bought the compact
version for her for another office she works in, which is very nice too, it
has full sized keys and takes up minimal desk space.  I then bought a Cherry
Strait for myself, which is really terrible by comparison, much noisier, and
as I say the keycaps lose their legends after a very short time.  Most
disappointing.

The real irritation about the Apple keyboards is the keys.  Where, you ask
yourself is the # key?  The layout seems to be neither us nor uk but
something horrible in between, so if you are not using an Apple computer you
end up writing xmodmap files to get  and @ in the right places, and then
they do not correspond to what is on the keys.  Its the usual story,
difference and irritation for its own sake, in a nutshell, everything one
detests about Apple.  Which is why, despite its being a superior keyboard in
itself, I won't be buying another one to replace the Cherry.

But like I say, my partner is delighted with them.  Of course, she cannot
see the xmodmap files

I have bought the Logitech OEMs for people who do a lot of typing.
professional writers, who did not want to spend much money, and they seem to
work very well for them.  Solid, not too much effort, not too noisy, last
for ever.  They are probably the best value of the membrane type.  I think
if you are not going to spend the money and get a real specialist keyboard,
this is the one to go for.

I have bought the PCKeyboards one, basically an old IBM buckling spring
recreation, for one guy who is an ex typesetter and so as nostalgic for that
very positive action.  He loves it, but you can hear it in the next room. 
Professional typists of a certain age really like these.  They are not too
expensive either, but they are not for everyone.

But were I a Mac user (or a lady wanting minimal space on the desktop, a
nice keyboard feel, and an elegant look) I would definitely get the corded
aluminum one, either the extended or the basic.  I know I will never get
mine back.

The social thing is, the PC/Smartphone/tabet is moving to becoming the main
vehicle
by which people get access to content - books, press, etc.  The borders
between
what is an app and what is content are blurring, and increasingly control of
the
app is a way of controlling the content that app gets for the user.  We have
to decide
whether we want this access to be controlled by corporations, or if we want
it to be open.

So the problem society has with Apple is not whether it will close down OSX,
I think 
Chipp is right, it will just as soon as it thinks it can.  Its what the
effect on society will be if that
model is generally adopted.  By, for instance, the main on-line bookseller,
in an era
when e-books are the only way to get lots of titles.

Re: WindowBoundingRect in Linux

2010-10-13 Thread Peter Alcibiades

I have done set the rect of stack xyz to the screen rect.

With Gnome this floats the stack above but touching the task bar, as with
all apps meximized, with no overlap.  With Fluxbox, the task bar is
overlappng and over the stack which occupies the whole screen, and this
happens with all apps.  With Flux however there are probably some options to
unset float over all, but I don't see how you would reproduce the Gnome
effect where the stack does not overlap the menu bar.  I seem to recall KDE
working the same way as Gnome, that would be KDE 3.5.  I have not tried
KDE4.x with rev.  This is debian squeeze.

If you want something specific tried, happy to do it.  I have just about
every WM under the sun installed!

Re: Linux Tao

2010-09-24 Thread Peter Alcibiades

Printing and fonts are the big deals.  I haven't encountered the slowness in
tables, and have never used ODBC.  I would check all displays to make sure
the fonts fit at different size displays, check revPrintField to make sure
it works (it does not for me), check print card, which used to print at
different sizes depending on the resolution of the display, so that it did
one thing on a 17 inch display and another on a 19 inch one.  It is probably
wise to restrict oneself to the fonts that come with all distributions.

Install the app itself in /opt, but dont put the data files there, they
should go in in /home/userx/myapp, and the preferences in
/home/userx/.myapp.

Also, check with kde as well as gnome.  And if they may use different
distributions, check with one debian derivative, one slackware derivative
and one Red Hat derivative.

The most accessible end user distributions for new users are Mandriva One
Gnome and PCLinuxOS, which comes with an intelligently done version of kde
and has the Mandriva control center.  If you want something smaller lighter
and faster, either Vector or Salix.  Still lighter, Puppy.   If you want
turnkey, sort of embedded system style, and totally minimalist, Slitaz.  If
you want minimalist userland in a full featured distro, use openbox or
fluxbox as the window manager in any distro.  You can get the effect of a
turnkey one app appliance that way if you arrange autostart.  

I have not found a distribution too minimalist for Rev to run on.

Re: LiveCode 4.5 and the midsummer (2010) save 60% on revStudio deal

2010-09-21 Thread Peter Alcibiades

It is always a Faustian pact, using closed source software, especially when
it is in rapid development.  Rev is perfectly entitled to abandon the Media
experiment.  It was noble, but evidently it did not work out.  I also think
its treated the Studio buyers such as myself fairly, it was entitled to
change the terms of renewal any time it wanted, and its done so.  

You pays your money and takes your choice.  Python is out there, its free,
it has an enormous variety of IDEs and editors, its thoroughly cross
platform, and it has a thriving community and innumerable tutorials and
textbooks and howtos.

But, it is rather a steeper learning curve, depending on where you are
coming from.

It is really not much different from Hypercard, is it?  It is someone else
that owns it, and you have really no say in what happens to it.  Do not, one
might advise, get too dependent on it, unless you really know what you are
getting into.  The thing about Rev is that there is an inbuilt conflict of
interest between two target markets, those who want to develop
non-commercially, and need it to be cheap, and those who are successfully
developing commercially, and can afford to pay decent fees.  In the end, its
going to be very hard to reconcile the two sets of needs.  They have done
their best with the mix and match pricing, but some bits have fallen by the
wayside.  Pity.

Re: [OT] The lessons of Ion

2010-09-18 Thread Peter Alcibiades

No, I missed out on the fun with vi and ed.  I am old enough to remember text
only interfaces however and felt that the GUI was a great liberation from
them.  This was Macs, and for many years I bought into 'ease of use' and
HIGs until the GUIs started to get more and more obtrusive and irritating
and I began to think about why I was still doing things in some ridiculously
complicated way - where were the shorcuts?  They were not there, because so
much of the GUI we know and love today evolved in an era when there were
lots of new users for whom things had to be dumbed down so they could have
instant usability.  

At some point I realized that it is worth spending a few hours learning
something unfamiliar in order to go three times as quickly and with much
less irritation at the end of it. 

The interesting thing about Ion is that it is not obscurantist, after only a
few days, although certainly it starts out feeling that way.  Its also an
interface that is definitely post GUI.  It is not an attempt to get rid of
the mouse.  Its a different approach to the relationship between the OS and
applications.  In a funny way, there is something early Mac like about it,
in the sense that the author has looked at the interface from the point of
view that what the OS interface must do is get out of the way and let you at
the applications, not make you click all the time in all these nesting menus
as if you were a four year old with a short attention span for learning.

Why do we accept that you have to learn how to use spreadsheets and word
processors and photo editors and programming languages, but think that
everyone should be able to pick up a computer and use it without learning
anything, and then be forced to carry on using it the same way on day 300 as
they did on day 1?

To get everything you need done in Ion only takes a dozen key combinations. 
Most of what you need can be done with three or four.  It does depend on the
applications working graphically as they always did.  But the OS interface
and all its widgets and windows and clicking through stuff just vanishes. It
is not like the extreme ones like ratpoison either where you virtually have
no mouse.  You do use the mouse in Ion, but only for a few OS things that
its best for.   So you just memorize the key combinations.  it only takes an
hour.  Why is that so awful?

Iceweasel, Icedove and so on in Debian?  Well, you probably know, its to do
with how open the branding is and what license it comes with.  I have too
much respect for the Debian guys to argue very much about it, if they do it,
they must have good reasons.

You have to give Ion a fair run to have the AHA experience.  And anytime you
get sick of it, you can flip to Gnome with a logout.  Try it.  But try it
for long enough to have that moment.

[OT] The lessons of Ion

2010-09-17 Thread Peter Alcibiades
The interesting thing about ion is that it makes you think really hard 
about what is ease of use, what is user friendly, what about those famous 
laws, the HIG, and the one about where your points of clicking ought to be 
that I always forget the name of because I hate it so much.  Here is how 
Ion2 works.

It is sort of tangentially relevant because if you were packing a one app 
OS, and you wanted a one app window manager, basically an embedded Rev app, 
ion would be one way to do it.  As long as you do not have too many new 
windows overlapping, however.

You start out looking at a totally blank screen with a top border which 
says 'empty frame' at the top.  It is also totally black except this 
border, which is a quite attractive shade of blue/grey, with white 
lettering on it.  There are no clues what to do next.

You are an insider or have a crib sheet, and so you know that F1 brings up 
a man page, F2 opens a terminal (the second most important thing a guy 
needs in his interface), and F3 lets you launch an app by name, which is a 
nice to have but not essential, because real men launch from a terminal, of 
course.  

So lets say you go ahead, and you type in icewe followed by a tab.  It will 
complete to iceweasel, which is the Debian name for firefox (yes, you had 
to know that), and when you hit enter, firefox launches and occupies the 
entire screen.  OK, you think, how about mail?  So you hit F3 again, now 
you type in kmail, hit enter, and up pops your email.  In a tab, also 
occupying the entire screen. 

Now you have an idea.  Why don't we split the screen?  So now you do alt+k 
s.  instantly, your pane is split into two equal parts, vertically, one 
like the first, black with nothing in it, the other with your two tabs.  
You want to resize?  alt+r and use the arrow keys.  You want to kill a 
panel?  Just right click in the border and close.  Same thing for a tab.

You are geting bored and desperately want the full Debian menu?  F12 brings 
it up.

It sounds impossible, and rather ridiculous.  But here is what is amazing.  
There comes a point at which all this suddenly becomes automatic as a way 
of working.  You do not think about it or look for your crib sheet, you 
just enter a few characters, and things happen.  You never have one window 
behind another, nothing ever overlaps.  You get used to splitting up your 
panes just so, for instance a calculator always open in the top right of 
your three or four.  A file manager under it.  Then the main window.  A 
terminal someplace of course.

There are no, zero widgets.  No taskbar.  No clock or date.  Nothing to 
tell you about the status of the network.  What is F2 for, after all?  
Presumably one of your little panes someplace is always running a terminal, 
so who needs widgets?  There are not even any borders.  All you see is apps 
and a tiny little bar at the top telling yoiu which tab you are in by going 
a paler shade of blue grey.

I have to tell you, this is an experience to make you think and scratch 
your head and think some more.  If Apple were right, it should not work.  
If Gnome were right, it should not work.  And on day 1 it does not.  But on 
day n, it not only works, it feels just perfectly right and automatic, your 
fingers just do things, and you forget you are using Ion, its just how 
things are done here.

Try it.  You will never feel the same about HIGs and that guy and his silly 
law again.  Fitts he might have been.  And you will never again confuse 
being easy to use on day 1 for the ignorant with being easy to use  when 
you know it well and are experienced.  No, they are completely different 
things.

Ion is a bit under resourced at the moment, as Richard pointed out.  But 
for the deprived minimalist, there are other alternatives, most notably 
from the nosuck school of software, wmii, awesome, and a couple more of 
that ilk.  If you are interested enough to try ion, have a look at wmii and 
its associates too.  Anyone with a serious interest in man computer 
interfaces will find it worth the effort.

Rev on two minimalist Linux distros

2010-09-16 Thread Peter Alcibiades
I have finally fired up Rev Media 4.0 on two minimalist Linux distributions 
as a start on the effort to discover whether the problems are really due to 
not having all the necessary files installed, and whether they are due to 
the mulifarious nature of Linux.

I began with Slitaz and Tiny Core, the latter of which gives new meaning to 
the expression 'minimalist'.  It is gui userland Linux system in 11 Mb.  If 
we still had floppies, it would just about be deliverable on a handful.  It 
uses almost none of the standard components.  All applications have to be 
installed from repository.  Both of these distros run in memory, so they 
are super fast.  

If you do this at home with Tiny Core, you should probably go with 3.1, 
just out.  I used 3.0.  It has 2.6 kernel, BusyBox, Tiny X, FLTK graphical 
user interface and flwm window manager.  Without getting too far into the 
recherche details, this is not your standard distro.  This is as minimalist 
as X windows can get.  Get it here:

tinycore_3.1.iso 

The other distribution is Slitaz, less minimalist, this has a whole 30 Mb 
and runs OpenBox, so a standard GUI, though not one most folks here may be 
familiar with.  It comes with XOrg and LXDE bits and pieces.  Midori as web  
browser, leafpad editor.  It is a usable desktop out of the box, unlike 
Tiny Core.  Get it here:

slitaz-3.0.iso 

I did not use these in VMs, but on a spare bare metal machine we now have 
available.  There is not going to be any difference if you run from CD in 
live mode, or if you install on hard drive, since in either case they both 
load directly to memory.  I don't use VMs for this stuff in the interests 
of eliminating as many variables as possible.

I made no modification whatever to Slitaz, but on Tiny Core, using the 
terminal, was unable to cd to the USB drive on which I had placed Media.  I 
therefore installed PCManFM from the repository, which brought down a 
modest bunch of dependencies, including Gtk2, all of which went by in a 
flash.  I didn't make a note of the others but can find out what they were 
if anyone is interested.

It would be nice to know what people think should be tested for to make 
this rigorous.  What I did was two things.  First, some minimal exercise of 
the IDE.  Created a new mainstack, dragged objects onto it, resized them.  
This worked fine.  The font (yes, singular is intended) could be resized 
fine.  The dictionary displayed and worked fine.  You can alternate between 
IDE and browse mode.  Buttons work.  Second thing was, when I had a stack, 
I then moved it to another virtual desktop, popped over to the virtual 
desktop and clicked it.  It instantly went back to the first one, where 
Media was open.  So virtual desktops do not work here.

It does not look like the problems could be missing dependencies.  Rev 
seems to work exactly the same if its in one of these totally minimalist 
environments, including with Tiny Core which has out of the box almost 
nothing the big ones have except what you absolutely have to have to run 
the kernel and a command line, or if it is full fledged and bloated like 
Gnome or KDE.

The environment I have found where Rev doesn't work at all is Ion2 window 
manager.  This is actually a very nice working environment, its becoming my 
favorite.  Its a tiling and tabbing WM.  You have tiles open, and your apps 
take up the entire tile, in a tab.  The tiles sit side by side on the 
desktop.  It handles pop-up windows in an unusual way, they all appear at 
the bottom of the tile you are in.  Rev does not like this, and it crashes.  
When you get used to Ion and know the keyboard shortcuts, its simply 
superb, fast, intuitive and very easy.  You start apps from the keyboard 
with auto fill to help.  Everything else seems to work with Ion, so this 
may be an indication that Rev is not standards compliant on the desktop 
issue.

So, tell me what else people want to see exercised, and I will do it, this 
is just a start.  And next week I will hopefully have time to do a full 
scale slackware install and bash around with that.  I am not all that 
lively lately, and the latest is, have a proper phone system to install  
in addition to a server.  But we will get to it, we really will.

Re: Rev on two minimalist Linux distros

2010-09-16 Thread Peter Alcibiades

Richmond, I am just trying to find out if there ARE any dependencies of note
that will not be included in most any distro.  I think the answer is
probably no based on this.  I do not expect anyone to use these distros in
anger, except for embedded systems.

I also wanted to  know, were any of the problems extinguished by lack of
apps and libraries.  The answer to that one seems to be no.

I think the answer is, the problems are intrinsic to the basic way Rev on
Linux has been implemented.

As for Ion, I do not think Rev should be made to work with all WMs.  I think
it should be standards compliant, and if it is, it will work on all.  I
think Ion is a fair test of this.  Make it work on Ion, and it will be
standards compliant and will work on all.  If its not standard compliant,
then, as now, it will work partly, and on some.  What we want is standards
compliance.

 It's a nice work, but I'm not sure it's the best choice for testing
standards. 

No, agreed. Or rather, admitted!  But Rev should however work with tiling
window managers, as long as everything else does with them.  If it did, it
would probably do virtual desktops right as well.  No, this is not a big
deal, the surprising thing was how well it works with almost nothing
standard installed except Gtk2.  That is on tiny core.  So whatever is going
wrong, it cannot be missing dependencies, can it?

Another review, more of an explanation for why.  In lots of ways, Mint is
Debian for the rest of us.  Or as Lynch puts it, Debian on steroids.  I like
Debian straight up, but can see the attractions of grafting on the Ubuntu
userland, or bits of it, onto it, for less minimalist tastes.  This version
sounds like the best of all worlds.

[OT] Linux Mint rolling release

2010-09-09 Thread Peter Alcibiades
This may also be of interest to some of you or your customers.  The problem 
with Ubuntu has always been that it is not a rolling release.  Mint is a 
well regarded flavor of Ubuntu.  Well now the Mint guys have now released a 
Debian based version of Mint, and it is a rolling release.

http://www.webupd8.org/2010/09/linux-mint-based-on-debian-released-and.html

May need a couple more point releases to get really smooth, but they will 
be there if they are not already in a couple of months.  Mint is a good 
team.

Re: [OT] Dead Video and no keyboard

2010-08-22 Thread Peter Alcibiades

Richmond, sincere apologies if the slightly flip tone was upsetting in
difficult circumstances.  We are struggling with our own expensive hardware
issues right now, so I know the feeling.

All the same, later and at leisure, the serious point is that it may no
longer be worth struggling with old hardware given how much things have
moved on since PPC days.   You can Hackintosh relatively cheap and lowish
end modern hardware, including Atom, and if you really want or need to run
OSX, and can't afford the current line of Mac boxes, if it were me, I'd do
it in a flash.

We recently had to get a server, and this was an eye opener.  We were going
to recycle an old desktop.  But instead, we bought for a couple hundred
euros a new server, roughly the size of a thick paperback.  15 watts
consumption, 500G disk, and it comes with Debian server already installed. 
And our old desktops are of a later generation than the PPCs.  There is a
point in computers where old hardware makes no sense, in terms of stress and
reliability.

Unlike with old motorbikes!  A friend rides a fabulous old Velocette, as
shiny and polished as the day it left the showroom, and as marvelous
engineering as ever.

Re: [RevServer + Rev on Linux] Checking if you have the needed libraries

2010-07-29 Thread Peter Alcibiades

I'm not knocking it, this is indeed absolutely the right way to track down
and fix dependencies.  But it would be a mistake to think this is the source
or the main source of the Rev on Linux problems.  You can pass the test,
have all the dependencies, which I always have had, and you will still have
the problems.   Yes, by all means give the info to people who have Linux
issues and don't know about ldd.  But with the caveat that if you are using
any modern mainstream distro, missing dependencies are not likely to be the
source of the problems.

If, and I think its a big if, if there were definite problems that have been
reported that can be tied to particular libraries being missing, that would
great, it would lead to instant solutions.  But I don't know of any.  Maybe
others do?

2010-07-29 Thread Peter Alcibiades

OK, I'm corrected.  But still, is there any evidence that cut and paste
problems in the editor, inability to handle fonts properly, issues with
printing, mutliple desktop issues, any evidence any of them are due to
library or dependency compatibility issues?  

Maybe they are - in that case lets have a list.  The problem at the moment
is that in the desktop version of Rev for Linux (I accept that the server
issues are different) you can follow Andre's instructions, satisfy yourself
you have no dependency problems, and then still not be able to print or use
fonts properly.

I am delinquent on hacking away at Slackware.  Life and age.  My goodness,
how we slow down as we age.  Get ready for it folks, it will not be fun.

Re: Rodeo: 1st naive question.

2010-07-26 Thread Peter Alcibiades

It seems to be an alternative to Rev, not a complement to it.  When fully
featured, you will write code in a different IDE, and it will run on any OS
that has an HTML5 compatible browser.  That is, it will run on all but
hobbyist OSs, and it will run in all mainstream browsers.

You will not need a copy of Rev or Media to either run the resulting code,
or to write it.

It seems to be a response to the banning of Rev apps from the Apple App
Store, but it does not offer any way of bypassing that and getting Rev apps
onto iPhone or iPad.  The response is to move to a different programming
language and environment which does not require the App Store for
distribution.

There seem to be two rather loose connexions to Rev.  The first appears to
be that you can port your Rev application automatically, at least in part,
to this new language.  One can imagine that automated ports from other
languages will appear also in HTML5 authoring tools.  The choice of Rev as
the first to port seems to come from its origins in the banning of this
particular language and the consequent disappointment of the Rodeo authors. 

The second is what one might call a marketing connexion:  those most
disappointed by the banning of Rev from the App Store are a natural early
adopter market for a product which will allow programs to be written for
iPad and iPhone, which do not require membership of the App Store.

The concept of easy to write cross platform HTML5 apps is very interesting,
but its an alternative to Rev, its not an extension to it.  It would be a
very interesting addition to Rev if instead of compiling for the Web, and
for plugin enabled browsers, one were able to compile to HTML5.  Doubtless
that day will come.  At that point, the two languages will be competitors.

Re: OT: Mac vs Win partisanship is unnecessary

2010-07-22 Thread Peter Alcibiades

Wise comment.  Mac and Windows seems from my perspective to be basically a
matter of personal preference with Apple being the more restrictive of the
two in the ways in which Open Source people care about.  Its Coke and Pepsi,
both having too much sugar, one a bit more than the other.  

Open Source is genuinely different, and reasonable people can differ, and
differ strongly, with its approach and values and its aims for the role of
computing and media in our society.  This is the source of some genuine
tensions for Rev.  But Curry is right, one needs to keep the issues with Rev
or Rodeo to the level of what makes business sense for everyone.  It is very
interesting that one result of the WebKit approach for Rodeo is that it puts
all OSs on the same level as far as accessing the applications once written.

The thing I remain cautious about with regard to iPhone and iPad is what
Apple's ultimate reaction will be when and if webkit based apps, from Rodeo
and other sources, start to bypass the app store on any scale.  Maybe they
never will, maybe the store is well enough established by now.  Maybe
corporate vertical market applications are where the money is, anyway. 
Jerry also takes the view there will be nothing they can or will do about
it, even if it happens.  Maybe so.  

The Rodeo vision however is genuinely cross platform, with a lot of the
heavy lifting done by stuff that is out there already in the form of
standards.  And when one thinks about Firefox and Explorer in this context,
they are in quite different situations, though neither one is webkit: 
Firefox could change, since webkit is OSS and so is webkit.  Explorer
obviously could not.  After all, Gnome changed with the new Galeon.  This
looked like a significant development.

You may not have been around during the wars of religion between Gnome and
KDE?  Gnome were the purists on OSS, and issued fatwas on KDE because KDE
were using Trolltech development environment, QT, which Gnome considered to
be not authentically open.  Which in some ways it really was not.  The
counter argument was that Gtk was unusable.  All this eventually got
amicably resolved when QT became open beyond reproach.  Even so, for Gnome
to adopt webkit looks like an interesting development which lends support to
the Rodeo peoples argument about it being the browser, not the OS, that you
need to write for.

The sleeper may be Apple.  The business model they have in mind is not one
where apps are written once and run equally on all OSs and desktop
environments, and where people access whatever content and apps they want
from whatever source they choose, any more than that is the model MS have in
mind.  But that is the logical end point of Rodeo and similar products. 
We'll see.

Re: [OT-Rodeo] Still waiting for the aha moment

2010-07-22 Thread Peter Alcibiades

If you can afford to drop your own money on overpriced hardware, then I
suppose you aren't in any kind of place to judge what I have to do to
survive.

This has been part of the reason I have installed Linux for some people. 
One case in particular comes to mind, a thoroughly infected machine where
the shop charge of $100 to clean it up was in conflict with feeding the
family.   Its easy to underestimate these considerations if one is
comfortable.

I have never done it, have no intention of doing it, and don't live in the
US, but if it were genuinely a case of feeding the family, I would hackntosh
for my own use right away.  It seems that you get the upgrade version of
Leopard, which is heavily discounted but can be used for clean installs. 
Get compatible hardware, and it seems to be perfectly doable. Dual booting
seems to be possible, but more complicated.  

At that point you are installing a retail copy of software you have bought
on a machine you own, admittedly in breach of EULA, which is a civil matter. 
The legal situation on copyright as long as you do not sell on is not clear. 
There are protections for this sort of activity in the copyright law, see
section 117 of Title 17.

But it might be simpler and a better use of the time to just use Rodeo from
a webkit browser, even given the limitations, if that is the only objective!

Sarah, I guess actually that you won't be limited to webkit based browsers,
as long as they fully support HTML5, is that not right?  Its a question of
supporting an open standard.   So the answer to the original question might
be, right now you need a webkit based browser for editing and app creation,
but in future, you'll be able to use any compliant browser, and one assumes
that will include (maybe it does even now) Firefox.

Have you tried with Firefox?

All the same, it cannot just be parcellite (never heard of that before)
because my crash on cut and paste occurred in a totally untweaked Debian new

then replace glipper with klipper and try to reproduce his result.  Weird

That is brilliant!  Cannot imagine how you ever thought of trying that.  I'll
fire up Gnome and have a go.

Much of today was spent struggling with trying to decode a .mny file for
someone.  Hopeless.  You cannot even go through it and extract the ascii. 
It will no longer open in any of the versions of money he has.  When you
repair the file, it tells you it is perfectly fine.  Then it declines to
open the one it allegedly repaired it to.  Nothing will import or convert
it.   Its at moments like this that you understand the point of open
formats.

Re: [OT-Rodeo] Still waiting for the aha moment

2010-07-21 Thread Peter Alcibiades

Webkit came about like this.  KDE, who make a Linux desktop environment
complete with office apps etc, developed a rendering engine as the basis for
their browser, called Konqueror.  It was open source..  Apple then took this
rendering engine and made it the basis of Safari.  There was tooing and
froing about whether Apple was passing its enhancements back, this was
eventually more or less resolved, and Webkit is now both the basis for
Safari and for open source browsers.  Which would include Midori, Chrome,
Konqueror, and even the Gnome browser, Galeon.  

Now, what can you do as a Windows user?  if I understand it properly, you
can write Rodeo pages in Windows as long as you use a webkit based browser
to connect to the online authoring tool.  This does not include Explorer or
Firefox, but there is no shortage.  This would apply to Linux too.

You cannot use the Mac based editor which Sarah has written, unless you
either buy yourself a Mac or make yourself a hackintosh.  Which is pretty
easy to do, not that I have any interest in doing it other than the
intellectual challenge maybe, but there are too many of those already.  But
you can still write Rodeo apps.

You can then connect to those web pages with any webkit based browser from
any OS.  So its not really mac-centric, and not even Rev centric, if I have
understood it properly.

They will shortly introduce the ability to run those pages on your own web
server, again through a webkit based browser.  You should also be able to
write web apps that run from your own device, again once they implement the
ability to run from any web server.  

Correct me if wrong on this very last point?

The hope and belief is that this means that you can write apps for the
iPhone and iPad.  Because you are targeting abilities built into the
browser, and you do not need to go through Apple's app store to get them to
the public.  Apple can no longer tell you and your buyers that swimsuit
photos are politically incorrect this year.

Will it work, and is it interesting?  Yes on the last count.  Someone asks
to what extent this allows you to port all the functionality of a Rev app to
the web.  This is something I am not clear about, and it would be nice to
know.  It is letting you compose apps within the limits of the webkit
engine.  It is also letting you translate the gui part of a Rev app into
standard web pages.  But it does not seem to be porting the whole
application to a web site, not even a webkit one.  Its doing part of that,
and delivering part of the functionality of the app. If you want the guts of
the thing, you write the rest of it in the Rodeo editor.

Is that pretty much right?

Re: [OT-Rodeo] Last minute call to get onboard with pre-realase conditions!

2010-07-20 Thread Peter Alcibiades

Yes, this is indeed a complete showstopper, there is no Mac hardware in the
future of quite a lot of us.  Its very interesting, in particular the
Transfer package is very interesting, but nothing is interesting enough to
move one back into that particular ghetto.

On the future of web apps on Apple hardware, Jerry is certain that the fact
that they are developing for webkit means that Apple will not be able to bar
this, even if it turns out to be a way of providing users with apps that
bypass the app store, and so means they have a motive to bar apps written
with it.  

We'll find out together.  Apple is ingenious, in control of their OS and all
apps, and ruthless with it.  The app store and associated control over what
the users do is central to the whole business model.  He may be right that
they will be unable to bar it, but the chances are that they will give it a
very serious try.  If you look at the history of webkit, the communications
back to the community from Apple, since it forked KHTML, compatibility
issues, you will find room for skepticism.   If you look at the history of
attempted content censorship via tha app store, and that is only the ones we
know about, because most of that is censored too, you'll not doubt their
commitment to control.

But hey, we'll see.  It will be most interesting.  Meanwhile, one assumes
that it means that Rodeo apps will run in Chrome or Konqueror or Galeon on
Linux?  Now that is interesting.  Its just a pity one cannot write them in
the OS they will run on.

Re: Playing a movie in Linux

2010-07-18 Thread Peter Alcibiades

Richmond, presumably you used the command to set which the movie player is? 
You did 

 set videoClipPlayer

and gave the full path of the executable?  I've never done this, but it
sounds like it ought to work.  Yes, the instructions in the dictionary on
what is the default do seem a little out of time.

Maybe the answer is, go out to shell and do the command in the shell.

If you do call it from a shell script, you will not have to give the
absolute path, just the command with the appropriate command line parameters
should do.

On what the default player is, it will likely depend on the DTE as well as
the distro.  With Gnome, it will be mplayer.  With a KDE install, it will be
the KDE player.  A bit like, if you are using Evolution for email, it will
open the Gnome browser unless you set the properties and tell it different. 
If you are using kmail, even on a basically Gnome system, it will open links
in Konqueror.  

We don't often do video, but the other day someone filmed a clip, copied it
from camera to desktop, and it  it simply played as soon as we opened it
without any further intervention.  So if you do use the shell, it should
work fine.

Re: RunRev, Linux, Multiple desktops

2010-07-17 Thread Peter Alcibiades

OK, this is how to reproduce it.

Fire up Rev, start a new stack, put a button on it.  

Now open the script editor, the property inspector, the dictionary.

Send the dictionary to desktop A, the property inspector to desktop B.

Now use either the dictionary, property inspector or the editor.  What
should happen is that all the windows reassemble themselves on just one
desktop, one over the other.

If you do the same thing in Open Office, you'll find that the help stays
open, stays in the same desktop, and you can move to and fro.  I no longer
write big complicated spreadsheets, thank heaven, but if you ever do, this
is invaluable.  You can have the full help application on one desktop and
what you're working on, on another, and so all the syntax of all those
functions is instantly available.  

What happens with Rev is that the functionality to move windows around is
there and working fine, what goes wrong is the next step, the ability to use
those windows where they are, and have them stay put.

But if  you've found a way, or a configuration, which allows this, that
would be truly wonderful!

They're a small outfit with limited resources, and to some extent we are in
this together.  I agree, its not optimal, but rolling up our sleeves is
probably the way to make progress.  Maybe there should be some buyer caveats
around the Linux version marketing materials also, to manage expectations. 
We have to give it a shot and see how Rev manages to respond.  Here's

Re: RunRev, Linux, Multiple desktops

2010-07-17 Thread Peter Alcibiades

This is on Fluxbox, Debian Squeeze, six desktops.  I did the recipe just to
verify, and crashed Flux and logged out, which is sort of amazing.  What
happened was, all the bits of Rev did indeed reassemble themselves onto one
desktop.  Then, in Fluxbox, you can flip through the desktops by rotating
the mousewheel.  Firefox was open, and kmail, in different desktops.  I
flipped the wheel, fairly fast, and bang, Flux crashed and we were back to
the login window (which at the moment is GDM).

Its not all that surprising, there is clearly something amiss with how Rev
handles X Windows.

Personal suggestion for fixing the Linux situation

2010-07-16 Thread Peter Alcibiades
Here is how I would go about tracking down these things.  Just to recap, 
the things we are seeking to track down are these four:

-- not all and only installed fonts are visible and useable
-- revPrintField does not work properly
-- virtual desktops don't work
-- editor slows down, freezes and crashes

Are there other priority areas?  There are other niggles, but are there 
other real basic functionaliry showstoppers?

My suggestion for going about tracking this down is quite different from 
what most people here will instinctively want to do.  The general view here 
is that Linux is an enormously complex mix of components, so the thing to 
do is pick some large general purpose distro and standardize on it.  I do 
not believe this to be the solution.  In fact, it is a wrong diagnosis of 
the problem.  This approach, which regards each distro as a distinct OS, is 
actually part of the problem.

Were I in charge of the effort I would proceed in EXACTLY THE REVERSE WAY.  
I would seek to find the minimum installation set, and within that, the one 
closest to the way packages are released by the developer, that will allow 
the reproduction of the problems.

You can argue about which distro will most readily meet these requirements, 
but if you want to start from something fairly simple and mainstream and 
not start compiling the whole thing from scratch, the contender that leaps 
out at you is Slackware.  I accept, there could be an argument for going 
even further down, like Slitaz or TinyCore.  Maybe that is worth a try as 
well, but they are not, as Slackware is, deliberately as untweaked as 
possible.

So I  would propose doing a minimal install of slackware, with nothing but 
the basic system and the most basic window manager, probably OpenBox.  
Maybe Metacity without Gnome desktop environment, if you want to be as 
close as possible to mainstream what it will have to run on.  But no 
Firefox, no OpenOffice, no apps at all.

If you can reproduce the problems on this sort of minimal install, then you 
are much closer to the source, because you have basically ruled out all 
distro specific issues.  If not, then start to add stuff until you do get 
the problems.

I understand that on this list there is a, well, a precoccupation, with 
Ubuntu as a distro for use.  This is not about use however, this is about a 
tool to get to the source of the problems.

I'm prepared to do serious work on this, but am not capable of writing 
patches to the IDE myself, and before getting started on the project, would 
welcome comment, and would like us to have an agreed approach, so what do 
you all think of the above?  It would also be nice to have some feedback 
from Edinburgh, to the effect that given contributions from us, they will 
do their bit also.

Re: RunRev Script Editor and Linux

2010-07-16 Thread Peter Alcibiades

There is no Linux per se. Linux is like blocks, modules that people
snap together at will. Without a known set of variables, Rev is very
likely to fail in some areas depending on which software the current
user has installed. 

Jacque, I don't think this is either true, or a useful explanation of why,
for instance, the editor crashes in my plain minimalist install of Debian on
cut and paste.  If it were true, then lots of applications that do cut and
paste, which is just about all of them, would crash.  The fact is, they do
not.  If it were true, then it would be almost impossible for virtual
desktops to work on all applications, but they do work.

Not by the way any sort of exotic way of working, commonplace for the
mainstream Linux user.  Commonplace in fact for ordinary users, once you
have showed them a few times how to use virtual desktops.

The way to look at this thing is to figure out what Rev is doing differently
from other apps.  What exactly is Rev doing with its editor, which is not a
terribly complicated sort of functionality, which makes this editor, unlike
any other, slowdown and freeze?  How exactly has Rev implemented the IDE so
that you can't put the property inspector on one desktop and the editor on
another?  How is Rev relating to the system print functionality that makes
revPrintField not work?  Where is it getting its font lists from?  Its not
the same place as every other app gets them.

Rev's problem is not that it is being installed with deep system
functionality into a complex multifarious environment, and some of this deep
functionality is understandably failing to work.  Rev's problem is that in
very simple functions, not deep at all,  it is not relating to identical and
unchanging features of the OS functionality in the same way that all the
other apps do.

As an analogy, it would be like writing your app so its installer failed to
put a starter icon on the desktop in Windows, and then saying, Oh Well, the
problem is no app store, people just install whatever they want on Windows,
so its an unpredictable environment.  Yes, it is, but that is not the
problem, the problem is how you wrote your installer to do something very
simple and access very basic functionality.

We need to stop making excuses!

Peter

If anyone wants to follow along with Slackware, this is where to get the
isos.  Only the first three CDs should be needed.  

http://spheniscus.uio.no/pub/linux/slackware/slackware-13.1-iso/

Be aware though, this is not exactly Linux as she is known today, this is
not the land of graphical installers, automatic and safe disk partitioning
and automatic dependency checks.  This is the command line and editing
config files.  Kind of fun to get back to it.  I am proposing to shrink the
partitions on my usual machine and do a clean install into free space, then
get going.

Re: Personal suggestion for fixing the Linux situation

2010-07-16 Thread Peter Alcibiades

The point is diagnostic.  If we knew the answer, there would be no need to do
this.  We need to find the lowest level at which the problems occur.  Or
don't occur.  At the moment, we have no idea if its Linux, Gnome, Ubuntu. 
We have no idea if its the basic packages as they come from the developer,
or the distro tweaks.  I want to know exactly when the problems happen, and
when they do not.  I want to get to something completely stripped down,
where maybe they will not happen, and then add stuff in a controlled way
till they do.

Its not macho.  its called scientific method.  Anyone with a better idea,
tell us.  So far in year upon year, no-one seems to have.

Re: Personal suggestion for fixing the Linux situation

2010-07-16 Thread Peter Alcibiades

Let me explain again.  You take the most minimalist possible Linux.  As
little gui tools as possible.  You take the distro that has the least
possible tweaking of any applications.  Then you try to find out:  do
virtual desktops work here?  Are all fonts visible here?  Does the editor
crash here?

If it works fine, you have learned something important.  You know that it is
something at a higher level than this that is causing the problem.  So you
start adding stuff, one thing at a time.  Eventually you can tie it down. 
Or it may be that in Slackware, it just works.  Then you know it is in other
distro tweaks and customizations.

This is not about what we use for goodness' sake!  I don't use Slackware any
more (though I would for servers).  This is about systematically tying down
what it is that is causing the problems, going through and eliminating
possible causes one after the other.

I don't mind the command line and editing text files at all, but its not
something that I want to do in my regular working system.  But there is no
other way of getting as close to bare metal as you can, and there is no
other way of eliminating most of the possible sources of the problems than
getting down to bare metal.

Re: RunRev Script Editor and Linux

2010-07-15 Thread Peter Alcibiades

I'm not (publicly at least) telling Kevin how to run his business.  I am
saying to him, I bought it, and I want it to work.  That is an entirely
legitimate point to make, first privately, then publicly if that has no
results.

Are native Linux apps distro and installation specific?  No.  Are they
compiled individually?  Yes.  You can download the source code for gedit and
compile it on any Linux installation with the classic

 configure
 make
 make install

We do not have a version of gedit which is tweaked for ion2 or Debian.  We
have a version of gedit that is written to be compileable so as to run on
any Linux.

Installation differs from distro to distro, because the various files may be
in different places, and they use different package managers.  The source
code is the same however.   But this specific install issue is not what is
going wrong with Rev.  It is not being released in an apt or rpm version for
installation, its being released as a universal binary that should just run
from the home directory, from /etc - from anyplace.  

Take RealBasic.  You download a package.  From memory, they have deb, rpm
and universal binary versions.  I picked the universal binary, put it in my
home directory, fired it up, and it runs.  If its correctly written why
wouldn't it?  If RealBasic can do it, Rev can do it.

We need to accept the real situation.  This is not about whether some of us
are suited to a particular programming language more than another.  Rev
suits me perfectly, when it works.  Its about whether core functionality of
a particular programming language works as required and as advertised.

Its not about standardizing on one distro.  Python does not have to
standardize on one distro, gedit does not, RealBasic does not, neither does
Rev.  The task is to run on Linux.  That's the standard.  If it don't run on
a plain vanilla install of Debian or Suse or Red Hat, it ain't a product.

It is not that Rev works perfectly, but only on one distro that it has
standardized on.  It does not work properly on any distro.  This is why,
while releasing a community distro with Rev preinstalled might be a step
towards diagnosing the problem,  it is not the solution to the problem.

It is not that some of us do not have the dependencies that Rev needs either
installed, properly installed, or properly configured.   This could happen I
suppose, but it is Rev's problem and not ours if it does.  A well behaved
Linux application will test for the short list of dependencies that Rev has
and notify the user if they are missing.   And they are, incidentally,
minimal.  It will be hard to find a mainstream distribution that does not
include them.

I have found Window Managers Rev will not run on.  I've not found a distro
it will not run on. 

It is not about whether Linux is suitable for the desktop.  It is, but if
even were it not, this would not be a valid excuse for releasing product
that does not work on it.  If you really don't think its suitable for the
desktop, don't sell product that is doomed for failure when attempting to
run on it.  Of course, Linux is perfectly suitable for the desktop, and
there is no reason why you cannot have stable applications on it. 
Debian/Ubuntu/Fedora/Suse have tens of thousands of them.

Should we use workarounds?

In a way yes, that was a route I took in the beginning.  The editor crashes,
use Geany.  The fonts don't show, use the few ones that do.  Printing?  Use
awk to reformat, or output to a handwritten .rtf file and pipe it into
OpenOffice.  Of course, all this is the reverse of write once and run
everywhere, but still.  The screen?  Reset the resolution every time you use
Rev?  This is where I draw the line.  No, I'm not doing that.  As a
customer, I won't be treated like this by any company.

What should we do for Rev?  It seems to me that the best thing we could do
for them is, stop making excuses for them.  Python, RealBasic, PyQT, PyGTK,
Perl, Lua they all run on Linux without all this stuff.  There is no
reason Rev cannot too.  It must, if its to have a future on the platform.

Alejandro, I have never compiled either one from source, they are included in

probably needs the basic gnome libraries.  I looked up Python dependencies
in Slackware, which does not automatically resolve them, and found a list
far too long to quote for the different bits of Python.

PyQT, PyGtk, PySqlite

Re: RunRev Script Editor and Linux

2010-07-14 Thread Peter Alcibiades

The choice of software components that makes Linux so appealing to its users
is also the reason that Rev doesn't work with everything.

Jacque, I'm afraid this is really not what is going on.  Consider a personal
case.  I now use mainly ion2 and openbox as window managers.  Before that it
was Fluxbox, before that both Gnome and KDE.  This means using at least
three or four different window managers, two different desktop environments,
different display managers also (I have mixed kdm, gdm, xdm, wdm with these
other choices).  I've also used different distros during this period,
Mandriva, Debian, Slitaz, Slax

Everything just works.  All the applications. This is the whole point of
Linux, or one of them:  it is not about proliferation of choice leading to
instability.  Its about having well defined layers and APIs, so that variety
is possible without impairing stability.   It makes no difference to a well
behaved Linux application which WM you are running, or which clipboard
manager.  If it does, the application has a problem, its not Linux that has
the problem, its not understandable if applications don't work consistently
with different flavors of Linux, it means they are defective.

The worst possible message the Linux users could send to Rev is that
slowdowns and crashes on cut and paste are acceptable, because Linux is just
like that.  This is a complete fantasy, as anyone with experience of Linux
knows.  The fact is, no editor I have ever used, and this included kedit,
gedit, leafpad, nano, kate, geany (no, I am too old for vim and emacs) ever
crashes or does anything untoward on cut and paste.  But Rev does, and its
done it on KDE, on Gnome, on Mandriva, on Debian.

On ion2, Rev will not even run.  All other applications run, one or two with
some slightly odd behavior, but none of them simply crash, like Rev does. 
(Ion2 is a minimalist tiling window manager, so it behaves very differently
from Gnome, but it is perfectly standards compliant and runs all other apps
perfectly).  On no WM does Rev run properly with multiple desktops.  This is
another clue if one needed one:  all other apps work fine with multiple
desktops, it is only Rev that does not, and it fails consistently across ALL
WMs.

Rev needs to wise up and fix itself to behing a well behaved Linux app.  We
all must under no circumstances let them off the hook on this.  Its not
Linux, its not the distro, its not the cilpboard manager, its not the WM. 
Its Rev, it is not a well behaved application.  And its the one out of step,
its not everyone else.

Re: RunRev Script Editor and Linux

2010-07-14 Thread Peter Alcibiades

Here is how it should work.  Fire up Open Office.  Now open the help screen. 
You now have an open document window and the help window on the same
desktop.  Now click in the very top left part of the help screen.  Or you
may have to right click it, I forget exactly how Gnome does it.  You should
be offered a choice to move it to a different desktop.  So pick one and put
it there.

Now you have the help open in one desktop and the document open in another,
and you move from one desktop to another, and have all the space available
on each for the windows you are using on them.  You should also be able to
drag the application windows from one desktop to another by using the little
icons on them, in the control panel.  Again, not sure if you have those
little windows in your control panel on Ubuntu by default; if not, add them
from the Gnome selection by right clicking on the panel and then adding the
virtual desktop display applet.

Now do the same thing with Rev.  Open up a couple of windows, the dictionary
would be a good one, then move the dictionary to a different desktop.  Or
move, for instance, the editor to a different desktop.  Now do something. 
Type into the editor, for instance, or look something up in the dictionary,
or add a new object to your stack.

You'll find that all the windows instantly return to one desktop.

Open Office on the other hand will allow you to keep whichever windows you
want on whichever desktop you want, and that is how it should work.

Tell me, why is there no custom version of gedit for each individual
distribution? Or Python?   This is a crazy idea.  The problems are not
because it is insufficiently tailored to one particular distribution that it
works flawlessly on, the problems are because it does not work properly on
Linux!



Exactly what i think...
There so many custom made
and specific Linux Distributions
that it's almost impossible to
keep track of them all, much
less to guarantee that your

Re: Question about Native Geometry

2010-06-28 Thread Peter Alcibiades

Jacque,

Its 1920 x 1080.  

When you set the text size, it works but only partly.  Some of the fonts
come up the right size, others do not.  Some parts of a para in the
dictionary are resized, other parts not.  The objects also are not resized,
so they don't fit any more.

To make any difference, it has to be set higher than 14, to 16 or 18.

I suspect that the reason it doesn't work properly is two fold.  One, the
objects do not resize to accept the new text size.  So perhaps Rev needs to
license Geometry Manager!  Second, we probably still have the old Rev font
problem:   not all fonts are recognized, and not all sizes are available
with all that are.   I had this problem a while ago, forget exactly which
release it was, when setting a font size of some fonts to an out of range
size resulted in them reverting to 10 or 12 pt.

I'll try Richmond's suggestions.

Peter

Question about Native Geometry

2010-06-25 Thread Peter Alcibiades
Rev on Linux has become pretty much unusable after buying a bigger screen 
with higher resolution, since unless you change the monitor to a lower 
resolution every time Rev starts up, the IDE is unreadably small.

Is it possible to use Native Geometry to fix this?

Re: [OT] Computer news from Kassel

2010-06-24 Thread Peter Alcibiades

The most dangerous argument any company can entertain on this subject.  The
question is, how the company handles reported product defects, what sort of
quality control it operates, whether the result of its resource allocations
is to end up doing many things badly, because it has taken on too much.

Does the fact, and it probably is one, that you can fix time, cost or
quality, but not all three at once, mean that its OK to have reported bugs
hanging around for years at a time undealt with?  Not necessarily unfixed,
but not dealt with and disposed of one way or another?  No.  In the end that
is the route to failure.  

Do whatever you do to appropriate and justifiable quality standards, and if
that means you have no resources left for the new products you would like to
introduce, tough.  Because you are not going to succeed as a company by
introducing them at the expense of overall quality, anyway.  There is no
better alternative on this than doing what you do, right.  And not doing the
things you do not have the resources to do right.

rev media and the player, question

2010-06-22 Thread Peter Alcibiades
I am thinking of offering to introduce one of my neighbor's sons to rev 
media.  His mother had voiced the view that she wished he would learn 
something creative or useful to do with his computer, if he was going to 
spend all this time on it, something she would feel better about than an 
endless sequence of gory shoot-em-ups.  One had to sympathize.

Does rev Player play stacks written in Media?  Or if you want to run them, 
do you have to have media installed on any machine you want to run them on?

I know Stackrunner won't play media generated stacks.  Pity.

Re: [OT] Computer news from Kassel

2010-06-22 Thread Peter Alcibiades

The price of doing some things well, if you are a company with limited
resources, is refusing to do everything badly.  

Or put it the other way, the price of trying to do too much is that you will
not do anything properly or well.  In the end, this is company wrecking. 
Its a life and death issue.

If Rev is really as overstretched as it looks, the first step is to close
down some stuff until they arrive at a smaller set of things that can be
done properly and to quality standards.  

If you can't fix the bugs in what you have, don't try to introduce more
products, as you will then be unable to fix the bugs in them also.  In the
common phrase, when in a hole, stop digging.

A common reaction to this situation is to deny it exists.  This is one of
the clearest symptoms of the illness.  The cure begins with acceptance and
acknowledgment of the problem.

Out of deference to Jacque, Richard and Richmond, I will now bite my tongue,

Re: [OT] Installing Linux fonts

2010-06-17 Thread Peter Alcibiades

Wolfgang, if this were the only problem, then every reboot would take care of
all the font problems, until you installed more fonts.

That is not my experience.  It varies from distro to distro, but my
experience is that after very many reboots, you still have a situation where
Rev fails to see some installed fonts, and sees other fonts that are not
installed, and that it is the only app with these problems in relation to
these fonts.

The cause of this, if it persists after reboot, cannot surely be the cache?

OT:  If you don't want that the user have to use...  Should be, if you
don't want the user TO HAVE TO USE.  You can't 'want that' someone does
something.  Dunno why, but it sounds wrong.  I know, its awful.  I often
have had the feeling in Europe and speaking a foreign language that it was
like trying to play a piano with gloves on.

You have to either have users who will do desktop icons for themselves, or
you have to write a shell script.  Or, there is a free Linux installer,
installjammer,  maybe that does it?  

Writing a shell script is probably the simplest.  You have to do other
things in way of installing, you probably need an install script anyway,
just include this in the script.

 This is all very charming, but I wonder how one would

You'd have to write an install or first use shell script.  Get the user,
then the root password, then write an extra line to /etc/sudoers.  The
advantage, though it will not matter to many, is that you don't store the
password in the app and don't have to supply it at each use of the commands,
and that you have restricted your privileges to one named user and one
variant of one command.  

Justin's solution is very nice, agreed.  Probably more practical and
certainly easier to do.  But, you do end up storing the password, and what
commands can be executed is not limited, nor is which user limited.  

Or maybe this is wrong?  That is what the effect, I think, would be on
Debian, which ships without sudo built in.  Maybe these distros that ship
with sudo are preconfigured to allow any user to sudo with their own login
password?  In which case they can do sudo su -?  I don't much like that idea
either, that cannot be surely?

Re: [OT] Installing Linux fonts

Can you imagine finding these directions on how to use installed fonts on a
Python mailing list?  Its simply ridiculous.  Rev needs to make the fonts
work on Rev like they do on all other applications. Or stop selling the
thing!

There are in excess of 20k packages in the Debian repositories.  None of
them, none, have problems recognizing installed fonts.  If you are a systems
programmer and writing programs that cannot manage fonts properly in the OS
for which you are writing, its time to stop.  Take up carpentry, or
plumbing.

Re: Shell Command with Sudo

Is there a reason you cannot use the NOPASSWD option in sudo?  Maybe this is
not how it works in OSX, but what you'd normally do is to edit /etc/sudoers
to allow this particular user to perform this particular command with the no
password option, and its done.  If you do this, the command can be limited
to one with specific options.  For instance, you can allow shutdown with the
-h option, but not the -r option.  No-one has to know the root password then
and it is not written anyplace.  Yes, you do have to know it to edit
/etc/sudoers.

Re: Linux question / problem

2010-06-11 Thread Peter Alcibiades

From memory, as I don't run Gnome any longer, having moved to Fluxbox or
ion2.

First create your link on the desktop or in the task bar. 

In the task bar, right click, then when you get to the add application
window, take custom application, give the full path as prompted - or browse
to the application.  On the desktop, right click, create application
launcher, giving the path in the same way.

In each case you should then be able to right click on the launcher, and
select properties.  If you then click on the icon, you will be able to
navigate to where your own custom icon is (presumably in the folder where
your app is located) and select it.  

If you do this with an app that has been installed through the package
manager, you'll find that it auto selects the right icon.  I don't know how
this binding works.  

Your app will be unusual, in that its icon will not be stored in any of the
usual places, which are /usr/share/icons or /usr/share/pixmaps (in Debian,
they may be someplace slightly different in Fedora).  If you want to create
an iconned desktop link during installation, I think you will have to do it
in the install shell script.

 Since it's a third party product, I think the rodeo site would be more

Yes.  

Basically, Rev is turning into (has turned into?  has always been?) a two
class product.  There is one class, which can buy the add-ins and thus get
access to all kinds of interesting functionality, and where the basic
functionality works properly.  

There is another class, which has just as much bought licenses, but which
gets to buy little or none of this add-on stuff, and in addition gets a
basic product that is not fit for professional development purposes.

The list increasingly reflects this fact, with more and more of the
discussion being simply irrelevant to licensees of the second class because
more and more of it is devoted to addons.  Not that moving this stuff to
another list will solve the real problem.  The problem is what functionality
one has access to, not where it is dicussed.  It is clear that tRev, Rodeo
etc are really core functionalities of the product, so it is quite
understandable that people think of it as one thing they are discussing.  

The user, given this, has a very simple choice to make at renewal time: 
does he or she keep on being treated like this, or does he or she move to
Python?

My own answer is, if I don't get some sensible roadmap for this thing, I am
not renewing.  As much out of a sense of indignation at how we are being
treated, as anything else.  It doesn't have to be instant catchup, it
probably cannot be.  It does not have to be instant porting of all add ons,
it probably cannot be.  But there has to be some acknowledgment of what is
going on, and some published plan to fix it.

Rev is entering dangerous territory here.  It is basically destroying its
credibility as a provider of a Linux development environment.  So
effectively, its betting its future on one view of the Linux market.  Could
work out, but its dangerous.  Risk is not what has happened, after the fact. 
Risk is what could happen before it.

Re: [OT] revMobile and SDK

2010-05-31 Thread Peter Alcibiades

Francois, there are probably two quite distinct issues, with two different
legalities.  Probably in the EU, at least in most jurisdictions, Apple will
not be able to enforce the prohibition on installing retail copies of OSX on
third party hardware.  It is interesting they have brought no cases despite
well publicized violations.  

But probably they will be able to continue the quite different policies of
tying the iDevices to the App Store and continuing to control what goes in
the App Store.  This is what underlies the SDK issue.  The situations are
very different, one can't really draw conclusions from one to the other. 
One is a question of the enforceability of a civil contract.  The other is
about whether a given policy breaches competition law and whether the
Commission will take action.  Very different.
