Meta-suggestion about conduct of discussions (was: Re: The new linux-il - a few tips to get you (re)started)

2009-01-30 Thread Omer Zak
May I suggest that someone open a Web page, which will summarize the
main points (both pro and con) of the discussion so far?
Once such a Web page exists and is available for modifications (such as
being a Wiki), we can start enforcing the netiquette of expecting people
to say something only if they add something new to the discussion?

This reminds me of the way my DEAF-INFO Web site got started more than
10 years ago.  In a deafness related mailing list, to which I was
subscribed, the same arguments were hashed again and again in endless
arguments.  Until one day I got tired from this and summarized the main
points in a FAQ (sort of), and out of the FAQ, the Web site grew up.

If such a page already exists and I am not aware of it, simply let me
(and the entire list) know about it and I'll be glad to add a mention of
it to my .sig in future postings to Linux-IL about this subject.

Re: make question

Hello Jason,

The following is what you need:
-=-=-=-
SOURCES = $(wildcard ../../some/other/path/*.eps)
TARGETS = $(patsubst ../../some/other/path/%.eps,%_fixed.eps)

all: $(TARGETS)

%_fixed.eps: ../../some/other/path/%.eps
[TAB] eps2eps $ $@

The above works with GNU Make (I use GNU Make 3.81 in Debian Etch).

DISCLAIMER: I did not actually check the above, but I use something very
similar in my own Makefiles.

Re: [OFFTOPIC] Daily Maily Spam

2008-12-09 Thread Omer Zak
Encouraged by advice from few Linux-IL subscribers, I clicked on the
unsubscription link provided: 
https://www.pac.co.il/RmvMails/[EMAIL PROTECTED]dm=DailyMaily
(quoted after censoring of my actual E-mail address).

I was directed to a form requesting me to fill my details - name,
company, phone numbers.  The field containing my E-mail address was
already filled.

This is a bad design - it seems that anyone can unsubscribe anyone else
from the mailing list.  A simpler unsubscription system would have
removed my subscription request as soon as I click on the link from the
E-mail message - and if the link was properly hashed, such a system
would also not allow other people to unsubscribe him.

When clicking on the הסירו אותי button, the unsubscription request was
rejected!!!  Red stars indicated that I must fill my first name and last
name.  Fortunately no further details (which I left empty) were
required.

Only after filling first name and last name fields, and clicking again
on the above button, I got confirmation that my unsubscription request
was accepted and will be processed within three business days.

They indicate that it is possible to get further help in unsubscribing
by sending E-mail to [EMAIL PROTECTED]

Interference with Markets (was: Re: [Haifux] Successful Windows Vista refund!!)

2008-12-06 Thread Omer Zak
I would be very wary of any law, which interferes with operation of
businesses.  There can always be unforeseen consequences.  One possible
consequence comes to one's mind:

Embedded system which is always sold with an operating system and
applications which allow its safe operation.
Then one has to define the borderline between a PC to be covered and an
embedded system to be exempted.

I have a better suggestion:

Encourage (by getting people to demand it) providers to sell PCs with
Linux, in which a VM is installed and runs a MS-Windows XP image.

Such a configuration will benefit the Free Software world by making it
easy to bridge between MS-Windows XP and Linux (no more having to
dual-boot the PC).

 VM anyone can install. Asking VM installed with windows xp image will
 open the door to charge extra charge for the image of XP.  After all,
 if it's not registered image, after 30 days you can't use it anymore.
 You need to re- install the image.  

So what?
1. The seller could sell, as part of the deal, a MS-Windows XP license.
2. Not everyone has the expertise to install, configure and optimize a
VM.  If the seller can profit from doing this in behalf of the buyer,
why not?

Roll your own Window Manager (was: Re: Re: grab focus)

I googled for the above and came up with:

http://en.wikipedia.org/wiki/Xmonad - a tiling window manager for
X-Window, written in Haskell.  Makes it possible to manage windows
without using a mouse.

http://cgi.cse.unsw.edu.au/~dons/blog/2007/05/01
http://cgi.cse.unsw.edu.au/~dons/blog/2007/05/17
Those articles describe the design of the above (written in Haskell, of

Haskell libraries) have sufficiently small memory footprint for use in
Erez D's system?

 1 and 3 will simply not work. Without a window manager there are just 
 two options. The X default is that the focus follows the mouse. Changing 
 this default will lead to the focus hanging on a certain window until 
 changed via the API. There is no mouse or keyboard sequence to tell X to 
 switch focus to another window. This is 100% the window manager's task.
 
 As for 2, it will work, but it is probably a gross overkill.
 
 How do you intend to identify the window that is to receive focus? Do 
 you have its Window ID? Do you want to do it by screen coordinates?
 
 If the former, RTFM the XSetInputFocus command. Aside from the overheads 
 (opening the X session), this is a one function command, and should be 
 fairly straight forward. Be warned, however, that it may very well not 
 work if a window manager happens to be running, as a window manager has 
 total veto power over any command affecting, well, windows (size, 
 display/hide, move etc.), so if you are trying to test it with KDE or 
 Gnome running, and it does nothing, don't despair. Try it again with no 
 window manager.

 Let me know if this works for you.

At impulse, I downloaded and compiled it.  The 'Usage:' path works for
me.

From usability point of view, the documentation (and maybe the
application itself) is missing a way to find out what window handles are
there now.  Remember - do not ask the window manager for this
information!

How about having xfocus display a list of the handles of all open
windows (along with some identifying information such as window title or
controlling process ID - for the user to match up with more information
using ps's output) when provided with no window handle argument?

When done, xfocus will be cool little application!

Re: gspca with GeForge FX 5200 experience, anyone? (was: Re: Webcam Recommendations?)

2008-11-24 Thread Omer Zak
I don't have gspca for my current kernel (2.6.24-etchnhalf.1-686) and
the gspca-source package didn't compile for it (there are Debian bugs
filed for it).

My story with gspca and the above video card is filed as bugs with
Debian:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=444314
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=423920

As far as I could see, no action was taken with those bugs.
So I am looking for people who experienced similar hang ups to help
diagnose the problem.

 You might also try the vesa driver to see if this problem appears,

[OFFTOPIC][JOB] Looking for the jobless PHP programmer

2008-11-11 Thread Omer Zak
Few days ago someone looked for a job for a PHP programmer, who was
recently laid off.
The E-mail message in question had the programmer's cellphone number.

Today I was contacted by someone, who is looking for a PHP programmer.
However I didn't find the aforementioned E-mail in archives - probably
suppressed because of the cellphone number.

If anyone has a copy of the message, can he/she forward it to me

I tried all 4 values of -I parameter of ping6:

I tried to ping6 both ipv6.google.com and 2001:4860:0:1001::68 (with -I

 So I see two options:
 1) Your firewall is blocking
 2) Your NAT hinders it

How to check for those possibilities?

 Try to play with tunnel_mode=v6anyv4
 and if_tunnel_v6v4=sit1, if_tunnel_v6udpv4=tun

My /etc/tsp/tspc.conf already has those settings.

 You can use ethereal (wireshark) to see the data being sent on port 3653 - as 
 well as the channel being built.

According to wireshark, the channel does get set up.

Re: Anyone succeeded in setting up anonymous IPv6 connectivity in Debian Etch?

2008-11-08 Thread Omer Zak
Hello Noam,
I may not have clarified myself.
Basically, when I set wireshark to listen to sit1, it captures my
ping6's Echo Request packets - but no replies.

I also found that there are no ppp0 or eth1 traffic corresponding to the
ping6-created sit1 traffic (my PC has two Ethernet cards, and eth1 is
the one which is connected to the ADSL modem; I use pptp and it creates
the network device ppp0; in other words, any IPv6 traffic is supposed to
pass through sit1-ppp0-eth1 and back).

I did see ppp0 traffic when tspc creates a tunnel, and it indicates
success in connecting to anon.freenet6.net (the IPv6 tunnel broker which
I use, as it supports anonymous logins).

After reading the 2008-08-25 - Configuring IPv6 using AARNet's free
broker article at http://www.nick-andrew.net/ I found that my iptables
firewall blocked protocol 41 packets in both input and output.

 You shouldn't see any ICMPv6 traffic! TSPC tunnels everything via 
 IPv4/IPv4UDP, so no ICMPv6 should be visible.

See my comment above.

This turned out to have been the case.
The following iptables commands fixed the problem
(where:   IPTABLES=/sbin/iptables
  INET_IFACE=ppp+):

$IPTABLES -A INPUT -p 41 -i $INET_IFACE -j ACCEPT
$IPTABLES -A OUTPUT -p 41 -o $INET_IFACE -j ACCEPT

Anyone succeeded in setting up anonymous IPv6 connectivity in Debian Etch?

2008-11-07 Thread Omer Zak
After installation of the tspc package (version 2.1.1-6), the tspc
daemon can be started and when started, it sets up the sit1 interface
(which can be viewed by /sbin/ifconfig) and ping6 to the assigned IPv6
address works.

Since I am reluctant to register for a channel broker, I use the
anonymous login to anon.freenet6.net.

The problem is that even after setting up the tunnel, attempts to ping6
IPv6 hosts (such as ipv6.google.com or www.ipv6.uni-muenster.de) yield
no response.

Is there anything I should do besides starting the aforementioned
daemon?
According to http://www.howtoforge.com/using-ipv6-on-debian-etch, I
should set up also sit0 interface.  What are the roles of sit0 and sit1,
and why are both necessary?  Is there anything I should do to get tspc
to set up also sit0?

Re: [YBA] Logical VS Visual Text Selection

2008-10-26 Thread Omer Zak
I think that Dov's idea is good one, and I'd be happy to see an
implementation of his idea.

Questions, whose answers require experimentation and tweaking:

1. Do we display sources and sinks over all the document or only at the
ends of the span, in which the cursor is now?

2. Do we display them all the time (toggled by the user in the same way
spaces are explicitly displayed in some wordprocessors, by displaying
small dots instead of spaces), or only when the user tries to select
text (i.e. automatically)?  And if automatically, how do we deal with
text displacement when sources and sinks show up/disappear?

3. Is this enough to make it easy to select text, or do we need also to
temporarily display text in logical-only ordering (see previous
discussion below)?

 Sorry to join the discussion so late, but I have an idea  that I
 believe would make both selection and caret position easier for the
 user in a BiDi context. The idea is to visually display the points of
 direction discontinuity. I like to call these a source when the two
 directions diverge, and a sink when the two direction converges. 
 
 Heres an example:
 
 Logical:  abcABCabc
 Visual with sources and sinks displayed: abc||CBA||abc
 
 where || is a glyph indicating a sink point and a || is a glyph
 indicating a source point. If a source and a sink meet they cancel
 out. The user may now easily place the caret at the left or the right
 side of the source and the sink points, which today is very difficult
 to do.
 
 I hope to create a concept implementation one day.

 Hello Jonathan,
 
 I think I begin to understand what you are trying to
 accomplish.  It is
 indeed difficult to precisely select a text segment when there
 are
 several spans of different directionality properties (LTR/RTL,
 strong/weak, overrides, etc.) at its borders.
 
 There are several possibilities for improving the selection
 GUI
 lookfeel in this case:
 
 1. Turn off BiDi ordering for the entire file (useful by
 itself for
 blind computer users; not directly related to our problem).
 
 2. Manually turn off BiDi ordering for a text segment (say, a
 paragraph)
 and then manually turn it back on.
 
 3. Use the metaphor of using one hand to straighten out a
 piece of paper
 when writing using the second hand (or straightening a piece
 of cloth
 while doing needlework): turn off BiDi ordering 5 glyphs
 before and 5
 glyphs after the mouse position (as the mouse moves, we
 suppress
 ordering of differing glyphs).  Have them displayed with
 background
 having different color.
 (The exact numbers are to be determined by usability tests,
 and be
 user-configurable through a setup menu.  So is the background
 color to
 be used in this case.)
 
 4. Have a small pop-up window, which displays the text around
 the mouse
 without BiDi ordering and let the user guide his mouse actions
 using the
 pop-up display.  The regular text display would be unchanged.
 
 It would be nice to get Arabic speakers to be involved in
 this, as
 Arabic presents a special problem - probably unreadable when
 the order
 of glyphs is reversed without additional processing.  Hebrew
 and Latin,
 in contrast, are still somewhat readable even in reverse
 direction.

 No, we mean temporaroly turn off bidi re-ordering for a text, do a logical

 then revert the display of the whole text back to bidi ordering. Selected 
 text wold be always be displayed in the same ordering as the unselected

Re: [YBA] Logical VS Visual Text Selection

2008-10-06 Thread Omer Zak
Hello Jonathan,
I think that visual caret motion with logical selection is the best
approach.  I do not see visual selection as an useful feature at all (at
least if it means what I understand it to mean).

If anything needs to be improved, then add, as a feature, a mode to turn
off BiDi ordering in the visual display of a text fragment.  This will
make easier the lives of people, who edit text, which mixes together
several RTL and LTR spans together with plethora of punctuation marks.

Another audience for such a feature is blind computer users, who wish to
edit text in Hebrew.  They read it LTR in Braille, and would like to
suppress the BiDi algorithm for such text.  Therefore, they need to turn
off BiDi ordering for a whole file.

About the best way to implement such a feature (how to
activate/deactivate) and whether the text is to be displayed in-line or
in another window - I'm deferring to other people to make suggestions.

Re: [YBA] Logical VS Visual Text Selection

2008-10-06 Thread Omer Zak
Another point which I forgot to mention in my previous E-mail about the
subject:
I urge everyone to consider carefully changes in the look and feel in
this area.  Especially if Brian Beck is not a regular Hebrew user.

I still remember the debacle in one of the versions of AbiWord few years
ago.  One day, someone with good intentions implemented a feature in
AbiWord, which caused Hebrew letters at word ends to automatically
assume their final form, if they had any - like in Arabic.

The problem was that unlike Arabic, in Hebrew there are cases in which
one wants to leave a letter in word's end at its non-final form (for
example, in acronyms).  Due to this, the feature ironically rendered
that particular version of AbiWord unusable for Hebrew wordprocessing.
After outcry, the feature was removed.

The feature implementor did not take into account the fact that in
Hebrew, the 5 final form letters have their own code points and their
own keys in the keyboard and people are already used to type them at
word ends.

Unlike Jonathan (who at least asked us), the guy (whom I'm leaving
unnamed) sinned in not first asking actual Hebrew users about the
potential utility of the feature.

Re: Financing for Wine BiDi

2008-09-04 Thread Omer Zak
So the budget is 1.25 months of work for fields 1,2, unknown for fields
3,4,5.  Given the numbers, fields 1,2 would cost about 19K NIS.

Assuming that 3,4,5 need 2.75 months of work, the total budget is 60K
NIS (not including Lingnu's own contribution in terms of reduced
prices).  I assume that it hugely underestimates the effort required in
4,5.

One way to raise the money is to identify 600 Linux users, who would
like to use Wine BiDi, and it is worth 100NIS at least for each of them,
and get 100NIS from each of them.  Since I somehow managed to lead
totally MS-free life, I don't use Wine so I'm not counted among those
600.

Are there Israeli companies, which deploy Linux solutions, and for which
it is worthwhile to avoid dual-booting or virtual machines yet support
clients, who still have legacy MS-Windows applications?
If yes, it may make sense to organize them into a consortium for
supporting Wine BiDi work.

About GSoC: this is why I asked about the budget for preparing the
project for GSoC - it has to be split into student-size bites and
probably there are also other preparations as well.

 Omer Zak wrote:

 These are rough estimates.
 
 Wine needs the following fields worked on:
 1. Move the BiDI code into Uniscribe, where it is on Windows
 2. Handle keyboard input language detection (essentially - rewrite 
 Wine's input processing - some of it already done)
 3. Start fixing the small bugs
 4. Implement a BiDi edit control
 5. Implement a BiDi rich edit control
 
 Lingnu is willing to chip in on such work, so the base for calculating 
 costs is 15Knis/month. Anyone contacting me for work on unrelated 
 projects should not expect those prices! 15K + employment overhead 
 translates to 110NIS/hour + VAT. Lets make it a round 125 sheqels/hour 
 with VAT.
 
 1. Move the infrastructure to where it belongs, split the BiDi algorithm 
 down to the components it has with Uniscribe, make sure it works as is, 
 implement a glue library (called LPK.DLL on Windows) to resolve circular 
 dependencies, and hook the functions back into where they are scattered 
 (GDI32.DLL, Advapi32.dll etc.): about a month of work.
 
 2. This is essential to get MSO working. A lot of the basic work is 
 done. You can find it attached to bug #735. Still quite a bit of work 
 getting it back into a state where it is commit ready. Lets mark it down 
 as a week's worth of work, though it might take more
 
 3. These are small bugs. None of them is too big in and on its own, but 
 they do require getting 1 above resolved before they can be approached.
 
 4. Unable to tell at this stage
 
 5. Same as 4, only worse :-)
 
 As for getting it done with GSoC, I tried it this year, and people said 
 it was too big a task. Oh well

 Thanks, Omer. I'll sign up for the first four spots: me, the wife, the
 daughter, and another on the way.

Only if you are willing to fork over 400NIS.
I do not see families of private people donating more than 100NIS per
family, regardless of number of users.

Shachar (Lingnu CEO): can you open a PayPal account (or equivalent) to
collect money from private people?  Or do you have another mechanism to
deal with, say, 300 small payments?

Shachar (Hamakor chairman): are there any tax advantages in getting
Hamakor to handle this, and work out any conflict of interest issues?

Shachar (again, Lingnu CEO): seems that we might pull this off - so we
need more realistic estimates of the project cost.  What budget do you
need to cover the cost of reviewing bugs, edit control development and
RTF edit control development?
With this figure, we can plan on 2-stage project, each stage to be
budgetted separately:
stage 1 - plan the project and make estimates.
stage 2 - actually execute.
If the output of stage 1 is made publicly available, then maybe parts of
stage 2 can be performed by outside volunteers with their own sources of
funding.

  That's another 596 heads to find. I
 will be sure to drop hints wherever I can.

Yes, it would help.

 Both Google and MS have a presence in Israel. If I were to write to
 Google suggesting that it might be in their interests to at least
 partially sponsor the project, to where would I direct them for
 further information?

Shoshana Forbes, being a Google insider, is the first name which comes

different from GSoC.

 PayPal is fine. The main problem is what happens if too few people say 
 I will? How do you deal with returning everyone's money? There is also 
 the bitch of issuing invoices to everyone involved - not a trivial task!

1. In the following, you outlined possible stages for the project - bug
fixes; edit control (non-RTF).  In this staged approach, you can start
the next stage once there are enough funds for the stage.
Also, in the PayPal donation page you can state that unused funds will
go to Hamakor to fund other projects.
2. Assuming that not everyone wants or needs a paper invoice, you could
just print the invoices but actually send them only to those who request
them.

  Shachar (again, Lingnu CEO): seems that we might pull this off - so we
  need more realistic estimates of the project cost.  What budget do you
  need to cover the cost of reviewing bugs, edit control development and
  RTF edit control development?

 I think we should leave RTF out of it right now. It does not add much to 
 the end user experience, and is probably a pain to implement.

Nevertheless, I suggest to plan also this.  If people still want it,
they'll fund also this part of the project.

  As for 
 edit - I'm supposed to be working on a project for ISOC that will 
 implement a BiDi edit control (not in Wine), and hopfully, once that 
 project is done, there will be enough reusable code to reduce the cost 
 of this element. At the moment, it is hard to estimate.

Make a worst case estimate (if you can't reuse the ISOC code).

 Please note that even without edit control, even just with #2 support, 
 MSO will work.
  With this figure, we can plan on 2-stage project, each stage to be
  budgetted separately:
  stage 1 - plan the project and make estimates.
  stage 2 - actually execute.
  If the output of stage 1 is made publicly available, then maybe parts of
  stage 2 can be performed by outside volunteers with their own sources of

 No problem with that. At the moment, the tasks are not really divisable. 
 Once #1 and #2 are done, hopefully, that will improve.

OK.  So now we need to raise 19K NIS to get #1, #2 done.  And then we'll
know what will be the cost estimate for #3, #4 and optionally #5.  Is
this the situation?

I suggest that people and corporations donate 35NIS/seat for #1,#2 and
put aside additional 85NIS/seat for #3,#4,#5.
(I took into account 10NIS per transaction to cover administrative
costs.)
I do not see myself as a Wine user, but to put some money where my big
mouth is, I'll donate 35NIS once there is a way to donate to this
project (without putting aside the additional 85NIS).

 Great, just great. So while considering all the apathy hang-vidia shows

 open-source operating systems, if even Linux users still buy their products 
 despite their general apathy towards us?

I use (relatively) low-end nVidia graphic cards, with the Free 'nv'
driver (rather than their proprietary driver).

According to the way Amos described his people's needs, the 'nv' driver
is enough for their needs.

What Amos is voting against with his employer's wallet (if he follows
through this plan) is against high-end graphic cards and those features,
which require proprietary drivers.  For the (relatively) low-end graphic
market, nVidia is effectively Free.

 So, the real problem is with people like you, who are too pragmatist on their 
 free software ideals, and still support companies like nVidia. I personally 
 am not going to buy a product that's not properly supported under Linux, just 
 so I can be sure I'm not supporting such abusive companies with my wallet.

Amos' people's display needs are properly supported under Linux using
only Free drivers (assuming that my recommendation passes his
evaluation).  It is an interesting philosophical discussion (which
properly belongs to another Linux-IL thread) whether buying a product
with features A+B, for use which needs only feature A, and such that
feature B is supported only by proprietary software - is a violation of
boycott against hardware which is not supported by Free Software.

By the way, I still remember the days in which ATI were anti Free

If Amos Shapira can wait a year, then let him buy ATI a year from now.
But if he needs a solution today, then several of the above promises are

  But if he needs a solution today, then several of the above promises are
  not relevant for him.
 
 Bzzt. You oversimplify:
  * Scenario I:
- Let's assume Amos buys today an old ATI (r300/r400 based)
  because he cannot wait.
 
- He gets reasonable 3D today (One of my Pentiums began
  doing compiz a year ago, after a regular update [ATI 9100IGP]).
 
- Items {2,3} *still* apply, because some of the future
  updates would improve even those old cards. For example,
  some of the updates Airlie work on, involve adding kernel
  modesetting support for the old r300/r400 as well.
  (this would help in monitor hotplugging, xrandr, etc.)
 
  * Scenario II:
- Amos buys today an ATI r500/r600 cards.
- Can use FOSS drivers today (no 3D acceleration etc.)
- Or can use proprietary drivers today.
- But because of items {2,3} he would get an *improved*
  FOSS drivers within the next year (cleanup, release engineering,
  distribution roll out).

Amos presumably needs a working solution TODAY.  Promises for bright
future are irrelevant.
If he chooses ATI cards, he should use only 1st reason to justify his
choice.  This reason may well be enough to make the justification.

 So with ATI we have an installment plan (Tashlumim)
 in two steps:
  * Get working (but limited) solution today (either old
cards or proprietary drivers or no 3D acceleration)
  * Get better support for the *same* hardware on the
next upgrade of your distro.

Plans of mice and men always change.  ATI might fold 8 months from now,
or be taken over by nVidia and have its product lines discontinued, or
switch to solar powered 3D holographic displays.

 Where's the second step for nVidia cards?

If they are cheap enough, then the following plan would make economic
sense:
1. Buy today the cheap nVidia cards (such as GeForce FX 5200, which I
chose because of its low price).
2. A year from now, ATI releases its gee whiz drivers.  Buy top of line
ATI cards to work with those drivers.  Their price will be lower than
the price you'd pay if you bought today the ATI cards.
3. Remove the cheap nVidia cards and have them recycled, or donate them
to one of the Linux based school computer labs.

The difference in price of the ATI cards will cover the cost of the
nVidia cards.
Caveat: the above would work unless Amos's people need to develop custom
graphic software which works only with one type of graphic cards.

Re: Preferred video card for Linux dual-head?

2008-08-24 Thread Omer Zak
In my PC I have two nVidia GeForce FX 5200 video cards.  One with AGP
form factor, and the other - with PCI form factor.
This was the cheapest way to add a second display to my PC, and worked
because my PC had unused PCI slots.

Software:  Debian Etch, with Xorg version 7.1.0-19.
The driver being used is 'nv', for both video cards.

The following /etc/X11/xorg.conf section specifies how both screens are
combined.

Section ServerLayout
Identifier  DualHead Default Layout
Screen  2nd Screen RightOf Default Screen
Screen  Default Screen
Option  Xinerama
InputDevice Generic Keyboard

Re: global interactive search-and-replace in bash?

2008-08-18 Thread Omer Zak
I sometimes encounter similar situations, and my answer to the question
is that it is easier to remember the command and reconstruct it than to
remember what name I gave to the script running the command with my
supplied arguments.  (Reminds me of Richard Feynman's approach for
remembering theorems - by deriving the proof each time a theorem is
needed.)

Maybe the right approach would be to have a script which collects
together all those one-liners and lets you choose one and supply
arguments.  Such a script would use 'dialog', 'whiptail' or 'zenity' to
prompt the user.
(Personally, I found 'dialog' to be more convenient than the other two
tools.)

א. אני חרש.
ב. במקום לחפש אותי בטלפון, פשוט תסיר אותי מרשימת התפוצה - ברור לך
מהתכתובת שאני מתייחס לפרסומיכם כאל דואר זבל.
ג. ודאי ידוע לך שההזמנה לפנות לצורך הסרה מרשימות תפוצה של דואר זבל אינה
יכולה להתקבל ברצינות, לאור העובדה שרבים מהזבלנים מנצלים פניות כאלה לרעה.
לכן התרופה היחידה היא מלכתחילה לא להפיץ דואר זבל.
ד. בקשר להאשמותיך כלפי גורמים אחרים שעובדים עם זבלנים - גם אם הן נכונות,
אין הדבר פוטר אותך מהחובה להמנע מלזבל בעצמך.
ה. ודאי ידוע לך, מההתכתבויות שמהן קצרתם את כתובת הדואל שלי לרשימות
התפוצה שלכם שמשמשות אותכם למשלוח דואר זבל, שאני מחייב כל מי ששולח לי
דואר זבל בתשלום פיצוי (שערכו כיום 2800 שח).  אם לא זכור לך, ראה ב:
http://www.zak.co.il/spamwarning.html
אם ברצונך לנקות את האווירה, אני ממליץ שהפיצוי ישולם בצורת תרומה למוסדות

* http://www.cancer.org.il/ תרומה של 1400 שח לאגודה למלחמה בסרטן, אתר 
* תרומה של 1400 שח לאגודת החרשים בישראל, אתר http://www.deaf.org.il/
בשני המקרים, תציין שהתרומה התבצעה בתור פיצוי על משלוח דואר זבל אליי,
שבחרתי להעבירו כתרומה אליהם במקום להנות ממנו אישית, ותבקש מהם שיעבירו
אלי אישור שאכן קיבלו מכם את התרומות, ושהן אינן חלק מהתרומות הרגילות שאתם
תורמים להם כל שנה (באם אתם תורמים להם).

[SOLVED] Which DNS servers did DHCP tell me to use?

2008-07-27 Thread Omer Zak
While I still do not know if and which command allows one to retrieve
all information transferred by a DHCP transaction, three people
(Geoffrey S. Mendelson, Ori Idan and Micha michf at post.tau.ac.il)
pointed out the file /etc/resolv.conf

Meanwhile, I found that when connection starts, the
original /etc/resolv.conf is renamed as /etc/resolv.conf.pppd-backup,
and a new /etc/resolv.conf is filled with values from the DHCP server.
When connection is severed, the original /etc/resolv.conf is restored.

There are also /etc/dhclient-script, /etc/dhclient.conf (consisting only
of comments), etc/dhcp3 (a directory, which has hooks for ntpdate and
samba).

Spam handling (was: Re: Israeli ISP and Blacklisting)

 1. SPAM is here to stay, mostly due to human nature. For people who want to
 sell something, this is an easy and cheap way to get more clients. This is

Asking myself whether it would have been to snip spam at its bud, by
making domain registrars and ISPs more diligent about eliminating spam,
my answer is that in the long range it was good that they were not
strict.

The reason is that not having to deal with spam would have left the
networks and applications more vulnerable to a well-timed spam attach,
which is bound to occur.

 2. SPAM is here to stay, from a technical point of view, due to the fact that
SMTP (and the following RFCs that enhance it) were not designed to deal
with sender authenticity. In fact, I believe that up to this day, an RFC
compliant mail system is required to accept the following:
MAIL FROM:

The following developments have the potential of changing the above
situation:
a. Massive switching of PC users from MS-Windows to a more secure OS,
removing them out of zombie networks.
b. New E-mail protocols, which are designed to prevent spam.  Those
protocols would supplant and eventually replace the existing ones.
c. Legal developments making domain registrars legally liable to the
actions of domains registered by them - with possibility of getting off
the hook by verifying the identity and addresses of the applicants.

 7. I do believe that some people on this list, while they have a theoretical
 point of view on how things should operate, lack the understanding of
 how things really turn out to be in the real world of ISP operations.
 Forgetting that the ISPs first, and foremost interest is to make money
 and make their shareholders happy is a fatal error, on the part of
 theoreticians. That however doesn't mean that everything ISPs do is
 acceptable, and sometimes very far from it. A balanced view however,
 that understands both the theory, and the practice is needed to be able
 to solve problems in the real ISP world.

Is it possible to set up non-profit ISPs?
How about mesh networks, based say upon WiFi and packet forwarding (old
Usenet style)?

 While it is theoretically possible to setup a non-profit ISP, it is not

 It takes A LOT of money to run an ISP - just the submarine uplinks costs a 
 couple of hundred K's of $ per month, and even if you manage to get a serious 
 staff working for you for free, or almost free (which I doubt, as ISP job is 
 24/7), you still need to buy expensive hardware, pay Bezeq for realms etc.
  
 So, unless you find someone with deep pockets who will fund this operation, I 
 don't see how it is possible.
  
 
 But I do like the idea :)

The nonprofit ISP's costs would be covered by payments from its clients,
just like for-profit ISPs.  The difference is that management will
answer to clients (via board of their representative, say) rather than
to profit-seeking owners.  Therefore the utility function to be
optimized will be to give the clients the best service possible at a
given cost, rather than to maximize the owners' profits regardless.

Another way to express it is that it is analogous to: by buying
subscription to the ISP's service, a client gets a share in the ISP (to
be surrendered when he terminates his subscription).  So he would
support a management which gives him good service rather than pay him
higher dividends.

I noticed that there were no comments about mesh networks with
WiFi/packet forwarding.  Such things are inherently non-profit.

I have E-mailed my ISP about this.

You may want to add to your E-mail to your ISP also your concerns that
since ALL Israeli ISPs are blacklisted, the entire country is in danger
of being backlisted as a country.

While the real reason for such an action would be political, the spam
handling situation is too convenient excuse to pass up.

 up their network from spammers.
 
 This means we are all losing emails we send because our ISPs are doing a bad

Anyone with spamassassin expertise?

2008-07-07 Thread Omer Zak
During the last few months, I get spam backscatter each few weeks - a
wave of few hundred bounce E-mail messages.
Almost all of them can be filtered using a rule which looks for my
E-mail address with the wrong sender name.

The line in question usually appears in an attachment, but sometimes it
is in the body of the bounce message.

Example:

  From: eliott feargus [EMAIL PROTECTED]
  (where eliott feargus could be anything except for Omer Zak
  case independent)

My PC has spamassassin version 3.2.3 installed (as part of the Debian
Etch set up), but it seems not to be trained to filter such E-mail.

Can anyone advise me how to instruct the E-mail delivery system to use
also this filtering criteria?

Thanks,

 Two questions (Spanish inquisition non-withstanding).
 1. How much do you want to pay for it?

Less than Asus EeePC.

 2. Does it have to be Intel based?

No, but it needs to be supported by Debian.

I see that two just became two squared. :-)

 3. How many units do you need?

One - for experiments and prototyping.

 4. USB host or device?

USB host, as I want to connect USB devices to it.

 Any computer on a chip system can provide you with everything you 
 asked for (well, you will need to adapt the battery yourself, but the 
 voltage and, more importantly, amperage are compatible with battery 
 operation).

Thanks for the keyword suggestion.

Anti-RTL mindset is similar to anti-accessibility mindset (was: Re: Openmoko Group sale)

2008-06-02 Thread Omer Zak
Chiming in the discussion, my 7 agorot (2 cents) are as follows.

The mindset of the Openmoko developers seems to me to be
anti-accessibility.

It stands to reason that they'll turn down requests to provide for
accessibility to people with disabilities.  The devices are probably
inherently unusable by blind people (like music for deaf people).
However, deaf people can be victimized by software, which beeps without
visual indication.  Color-blind people can be victimized by software UI
design, which relies too much on color cues, and which does not provide
for ability to change colors.  Epileptic people can be victimized by
software, which insists upon blinking.

Nevertheless, the percentage of those people in the general population
is small enough for the Openmoko to make a case for ignoring their
needs, much the same way they make a case for ignoring the needs of RTL
people.

Re: mknod

Why doesn't that developer have his own PC?
If the developer needs to write his own kernel modules, then he needs
root privileges anyway.
But if he just develops applications for an embedded system, which
already has debugged modules, then the devices can be created beforehand
(manually or via udev, as already suggested by someone else).

How to deal with bounce messages spam?

2008-04-30 Thread Omer Zak
My E-mail address somehow found its way into the reservoir of E-mail
addresses used by some spambots for forging the From: line in E-mail
messages.

The consequence is that during recent days I have been flooded with
bounce messages from mailer-daemon and postmaster of various domains,
which bounced back spam messages whose delivery to the final destination
failed.

My practice so far has been to filter spam messages into a junk folder
and manually inspectdelete them, so that I can catch any false
positives.
However, given the flood of the bounce messages spam, I'll need to
automatically get rid of them.

Fortunately, almost all of the messages which I want to automatically
delete seem to match the rule that the original message has a From:
line with my E-mail address but with another name.

The question is - is it possible and how to configure SpamAssasin and/or
Evolution (my E-mail client) to reject those messages (or file them in a
junk2 folder, for rapid deletion)?

  Thanks,
   --- Omer

  2. How to get the accounts notarized (or whatever) by a CPA?
 
 I don't think you would want to. In order for YOU to enter the data into
 an apporoved accounting program, you must be a level 3 (as in 1 is the
 lowest) certified bookkeeper.

I have been using an accounting program running in MS-DOS (!), but now
(due to reasons into which I'll not go now) I am faced with either going
back to fully manual method or switching to a Linux based accounting
program.

 If you use an alternate method of entering the data and keeping the books,
 or you are not certified, you can not legally submit the data to the tax
 authorities. 
 
 However if you provide the data to your accountant and they enter the data
 or have a level 3 certified bookkeeper enter it, those reports may be
 submitted.

My work flow has always been to provide the data to my CPA and have him
submit the reports.  The fact that this work flow will stay the same is
what is simplifying the problem.

 For best results and less cost, you can submit your data to them in a 
 format they can import the data into their program. From what I understand
 all the approved programs can read .xls (Exel format) spreadsheets.

This can be part of the proposed GNUCash-for-Israel HOWTO - how to
prepare a .xls file so that its contents can be imported into all
accounting programs approved in Israel.

Postmortem (Re: Connecting more than one display to the same PC)

2008-03-09 Thread Omer Zak
Now I have two working displays connected to my PC.  My PC's motherboard
still has one free PCI slot, which I might use for another video card
and 3rd display in the future.

I ended up buying 2nd GeForce FX 5200, so now I have two FX 5200 cards,
one having AGP interface and the other - PCI interface.
The 17 display was moved to the PCI card, and the 20/wide display
(which I bought as well) is connected via the AGP interface.  SVGA
cables are used for both, although the new display has also DVI
interface.

I worked at few stages.
First stage was to disconnect the 17 display and connect the 20
display to the AGP card.

I invoked (in my Debian Etch system):
dpkg-reconfigure -phigh xserver-xorg and it created /etc/X11/xorg.conf,
which supports modes beyond 1280x1024 (namely 1680x1050, 1440x1440 and
1440x900).

Then I inserted the second FX 5200, and after turning the PC back on, I
ran lspci and manually edited the /etc/X11/xorg.conf according to
instructions in http://www.linux.com/articles/113516 and
invoked /etc/init.d/kdm restart (to restart the X-Window server).

Once both displays worked, I invoked the Configure - KDE Control Module
(in KDE 3.5: start menu/Settings/Peripherals/Display/Multiple Monitors),
identified all displays (using the Identify All Displays button), and
configured where I want to see unmanaged windows (in the display
containing the pointer) and the splash screen (in the 20 display -
display 2).  The Multiple Monitor Support checked items were
satisfactory for me, so I didn't change them.

After backing up my manually edited /etc/X11/xorg.conf file, I ran again
dpkg-reconfigure as above and noticed that the file version created by
it overwrote my version of /etc/X11/xorg.conf.  So I suppose that after
each upgrade of the xserver-xorg package I'll have to revisit
configuration.

One problem I did not solve.  I want to have the menu start button (in
the left bottom corner of display 1) to appear in both displays - but
did not find how to configure KDE 3.5 to do this.

Thanks to Michael Tewner, Geoffrey S. Mendelson and Gilboa Davara who
answered my questions, even though I did not use their answers after
all.

Connecting more than one display to the same PC

2008-03-08 Thread Omer Zak
After reading the article in http://www.linux.com/articles/113516 about
this subject and seeing how simple it is to configure X-Window to handle
two displays, I would like to do this in my PC.

* What is your experience with driving 2-3 displays from your Linux PC?
* Given the following situation, what would you recommend/keep away
from?

Hardware:
My PC currently has the nVidia Corporation NV34 [GeForce FX 5200] (rev
a1) (according to lspci) video card in an AGP slot.
It also has two free PCI slots.

Installation:
Linux flavor being used - Debian Etch, updated packages.
X-Window: Xorg version: 7.1.0-19.
Video driver being used: /usr/lib/xorg/modules/drivers/nv_drv.so
From /var/log/Xorg.0.log:
  (II) Module nv: vendor=X.Org Foundation
  compiled for 7.1.1, module version = 1.2.0
  Module class: X.Org Video Driver

* Specific issues and questions:

1. What is the best video card nowadays, by the following criteria:
- Linux support
- Support for OpenGL in Linux
- Support for 3D effects in Linux
- On the other hand, I am not a gamer and don't expect to play games on
it.
- I need it to be a PCI card, as the AGP slot is already occupied.
However if an AGP card is much better, please let me know about it as
well.

2. Is there any problem using two different video cards (say, nVidia and
ATI) in the same PC?

3. Not directly related to the above, but insights would be helpful:

I have a problem with the gspca Webcam driver - when trying to use any
application using a Webcam, the process gets stuck and cannot be killed
(i.e. the problem is in the driver).  The problem seems to be associated
with the video card/driver, because in another PC (with an ATI driver),
the gspca driver and Webcam work OK.

Does anyone know anything about this problem?  I already asked the gspca
developer and in some IRC forums - but found no help there.

  You get all the benefits of using XML and no parsing overhead.
 Well, you lose one benefit - it's no longer in a standard parsable, nor 
 even textual, format.

Not necessarily.
If you have a converter between XML and your binary format, and make it
available everywhere your application is available, then the messages
would still effectively be available in XML.  You'll need also some way
to force people to modify the converter whenever they modify the schema.

Another way is to use one of the serializer/unserializer modules
available in scripting languages such as Python or Perl.  This will
transform between your data structure's internal representation and a
binary format.

 It does much more than what you need, but I'm sure that the information
 you seek is in fact stored in the output (I believe a simple SAX

 the dev environ). Besides - you could probably use more than just the
 location of the defs.

From a brief glance at the gccxml Web site, the project looks to be
relatively unmaintained (at least).  The most recent release was at
2004.

Installing Emacs22 on Debian Etch

2007-12-29 Thread Omer Zak
When I looked for an Emacs22 package for Debian Etch, I found that the
regular Debian backports Web site at http://www.backports.org/ does not
include a backport of this package.

(The reason I looked for this version of Emacs was because of its
network connection support by means of ELISP functions like
make-network-process and open-network-stream.
It also has a cua mode, which allows you to use the now-standard C-x,
C-c and C-v key combinations for the standard operations.)

Today I found that the Emacs Wiki Web site has a page about exactly this
subject: http://www.emacswiki.org/cgi-bin/emacs-en/OnDebianEtch

Following directions, Emacs22 was successfully installed and made the
default.  Details are as follows.

1. I worked as root, so I used the following to authenticate the package
source hype.sourceforge.jp/f:
# wget http://hype.sourceforge.jp/f/A7F20B7E.gpg -O- | apt-key add -

2. As directed, I added the following lines to /etc/apt/sources.list:
deb http://hype.sourceforge.jp/f etch backports
deb-src http://hype.sourceforge.jp/f etch backports

3. I used aptitude (rather than the various apt-get commands recommended
by the aforementioned Web page).  As usual, it complains when activated
for the first time after adding another source.  I restarted it, and the
complaint went away.

When running update, aptitude recommended that several packages (for
example, PHP5 related ones) be upgraded.  I blocked everything by the F
command (Forbid Upgrade), and selected the Emacs22 packages.

aptitude informed about a buffer overflow error, which was already fixed
in the Debian Lenny version of Emacs22.  I allowed it to be installed.
Installation proceeded without further incidents.

4. After installation, I checked which version of emacs is in effect
using:
# update-alternatives --display emacs
Since I found it to be pointing at /usr/bin/emacs22-x rather
than /usr/bin/emacs21-x, no further action was needed.

Re: Run out of inodes

2007-12-27 Thread Omer Zak
Few years ago a Linux system, which I used, ran out of inodes once in a
while.  The reason was that a directory in /var (I do not remember its
name) got filled by thousands of zero-length files, due to a botched
error recovery attempt by some daemon.  The cure was to delete all those
files.

I would suggest that you look for obsolete archive files in /var/log and
for other obsolete stuff in other /var subdirectories.  Once those files
re deleted, you should be able to free several inodes.

Re: missing /home

2007-12-20 Thread Omer Zak
When checking for free disk space, check also inodes (by df -i).
According to past experience, when a partition runs out of inodes,
sometimes the system manages to continue to work and erratically fail
(when processes need to create new files without deleting others
beforehand).

Another shot in the dark:  which filesystem are you using on home -
ext2, ext3, reiserfs, ... ?

You provided us with a description of the expected and actual behaviors.
However, it would be better if you provided us with the full source code
of a sample program involving ptrace, as written by you.

From skimming man ptrace, it appears that the subprocess is stopped by
