[nlug] OT: Liquid Latex

[Jack]

Where can I find liquid latex in Nashville?  I need a couple of
gallons.  At a reasonable
price of course. (in the range of $50/gal or less)

No, not computer related, but I thought this is a pretty diverse set
of folks that might
know!

TIA

[nlug] Re: Linus: "Microsoft Hated is a Disease"

[Jack]

I have to admit that my dislike of Micro$oft started in 1976 with Bill Gates
'open letter to computer hobbyists'.  Prior
to that I had been a M$ supporter.  I had a computer that could run M$
4KBasic at the time.  I did not have it,
I did not purchase it, either before or for sure not after the publication
of that letter. ... I used machine, assembler,
C, and 'open' basics that were available and being developed in that era.

http://en.wikipedia.org/wiki/Open_Letter_to_Hobbyists -- comments about 'the
letter'
http://www.digibarn.com/collections/newsletters/homebrew/V2_01/index.html --
read the letter here

It set the tone for my understanding of M$ from then on.  And given the
actions of M$ over the years (purchasing
companies with good products, rebranding/renaming them, terminating
non-Intel/non-Windows versions of their
products and removing them from the market.  And other predatory techniques
(that the EU has had the nerve
to prosecute, and the USA has not).  M$ could be branded a economic
terrorist by some with reasonable
substantiation.

So do I feel sorry for M$?  Not likely.  They made their own PR and
technological bed.  They need no sympathy.
I run some of their products, typically when developers have not come up
with a reasonable alternative or they
'develop first for the mass market'.  I even understand the developers
perspective.

Is any of this attitude because Apple, Linux, or anything else is better?
No.  All tools have their place.  M$
like all software and hardware companies develop tools.  Theirs is often
priced competitively for the service
it provides.  If it was not, the market would go elsewhere.  But I seen to
keep haring the old saw: "if the only
tool you have is a hammer, all problems look like nails".

Other have a different opinion.  ...   Am I right?  Probably not totally but
after 33 years, I doubt my attitude will change much.

Time for me to switch to another channel. ... This one is raising my blood
pressure to much.

Enjoy, ... Jack

[nlug] Re: Exercise in massive overkill

[Jack]

Back in a former life, I was active in a user group elsewhere.

I considered putting in a 'bar swipe' on a 'checkin computer'.

The first time you visit/join, put in name, address, email, etc,
and choose some card, like Visa, Kroger, Drivers License, etc,
and swipe it.  The idea was to 'register' the card (like take the fields
in swipe strip 1 and encrypt it using password type, one way encrypting
method, and just saved.  Give the folks a 'sticker', so they can remember
what card they used.

The next meeting, just swipe the card, and you are 'registered' for
having attended that meeting.

We also found that it helpped to give away schwag, one or two things,
at each meeting.

When you have logged in, for the meeting, a random number generator
is run at the end of the meeting to choose a winner.

Officers were automatically excluded at that group, but that was
their way.

Schwag was usually an O'Riley book, software from SCO, Red Hat, etc.
Whomever we could email and beg stuff from.  The Books, we requested
a 500 word (more or less) review by the next meeting that we put on the
web site, and the 'schwag queen' (officer that handled getting the schwag,
usually the president, or vp) would send a copy and a link back to the
company.  It helped keep up 'relations' with the vendors.  Often when
we called and had 'commercial vendors' present, we would suggest them
bringing the schwag, t-shirt, mug, whatever.

We also gave schwag credit on our web site for helping sponsor the
meetings.

Enough of my ADD wanderings.  If it something sounds good, use it.
If not, the this is just more wast of all our bandwidth!

[nlug] Re: Exercise in massive overkill

Some folks are skiddish about signing up for anything.  If you could do a
'quick and easy'
kind of a signup, not requiring anything if they insist, but requesting
information.

Also, give away businss cards whether they sign up or not
with the logo, and how to sign up for the mailing list, and the web address.
Possibly a few key works to catch the eye, like 'free', 'install fests',
'classes', 'email lists',
'open source', etc. listed on the cards as well. ... Just a thought.

[nlug] OT: Infrared Thermography on the Cheap (of course)

[Jack]

Is there a set of filters that I could put on a digital camera that would
block out all but the infrared?

Has someone here done this before? (or links to sites that show a DIY version)

This is a project for my wife (thus high priority for me :) - to possibly use
this kind of technology to 'see' tempratures in the 90 to 120 F range.
Additional range would be nice, and it doesn't need to be 'exact', just relative
temps.

[nlug] Re: OT: Infrared Thermography on the Cheap (of course)

[Jack]

The farrier my wife uses talked about another customer of his that has
one and is getting
'certified' in its use.  So he started taking pictures of horses.
There are lots of issues that
allows the horse having a 'temperature' to pick up problems before a
farrier or a vet can find
them otherwise.  Having 40 horses to take care of, being able to do
preemptive care would
be a real benefit.

yes, the 'big boy tools' I have heard of do use some cryogenic
cooling, and in the 'old days'
you could do some of this by using infrared film in a regular camera
along with some filters.
I just didn't know if some of this has 'transmuted' to the low cost arena.

Doing this for her would make me a hero for a day or so around here :)

[nlug] Need recomentation on a new wifi-ethernet game adapter with detachable antenna

[Jack]

I have an old USRobotics wireless game adapter that I use to help gateway my
house onto the
internet from another location with a high gain directional antenna.

The USR adapter gave up the ghost.  What I found to replace it seems to all
have 'integrated' antenna,
so that I would have to take 'hardware action' to replace it with the
antenna I have been using.

Must be Wifi to ethernet, not USB.

Suggestions on a good device that is also inexpenseive?

Yes, you have the right idea, Don.

I was wondering if putting a device in 'access point' mode would work for
this purpose,
that is if it would act as a bridge or if it insists on being more 'active'
than that.

yes, that is why I was using a ethernet game adapter.  Just trying to see if
some
of the access point mode would work that way too.

Unless you are planning completing degree through UoP,
contact the registrar at your 'desination' or 'terminal' college where you
plan on completing a degree, and figure out what is 'accepted' there.
It can save lots of time, anguish, and $$$.

[nlug] Re: OT: Online College

[Jack]

Back when mainframes roamed, 'programming schools' abounded, but
college degrees were
'the ticket'.

As Howard mentioned, in recent years, and as major technology changes
come about,
'certificates' started to be 'the thing'.

I have a degree, and have stayed away from certificates, just because
I think people need to
know how to think their way through a problem, rather than know it is
on one drop down menu
vs another.

When HR folks get a job request, they are given a set of 'buzzwords'
to look for.  Once you
get enough things checked off, you are typically passed over to the
hiring manager that may
or may not know how to filter your CV or Resume.  But this is the
person that must eventually
say YES, all others in the process can have a vote, but typically
their only vote option that
is listened to is NO.

Yes, I am cynical about the whole process.

If you want to work for someone else, be prepared to send out a ton of
resume's, get the door
slamed in your face a lot.  But also spend time networking.  If you
don't know how, ask.
Attending NLUG, your church(etc), social clubs, civic clubs,etc and
build a network of
acquantances that you communicate with regularly.  Dont say 'do you
have a job for me',
but ask, 'Do you know someone who has a contact that could help me
find a job doing xyzzy?'

Also networks work better with exercise.  Expect to be asked for input
and help from others
too.  Electronic networks are great, but people networking is where
the power is, whether
it is electronic, in person, or your telephone list.

But I digress, even again.

Personally, I think no education is ever 'lost', it all adds to the
fabric of your life.  If you want
education to make your life more rich, get a degree, the more and
higher the better.  If you
want to just get one more job, find out what is needed and get a
'certificate' in that area.
Neither of these guarantees a job, but they both up the chances over
'competition' that has
neither.

If you want a more 'educated' job, researcher, college professor, etc,
higher degrees (PhD, or
even a few post doc's) are imperative.

I say all this, and here I stand without a job for over a year.
Life goes on.

Story:
  I was working for a consulting company that had about 100 Windows
admins's and 400 UNIX admins working
for it.  RedHat wanted to start their certification program.  They
took about 100 UNIX admins and 50 Windows
and just gave them the RHCE test, all passed but one Windows guy on
the first try.  The next time they tried
it with a different set of tests and people, most still passed after
some training, but the failure rate was much
higher.
  M$oft heard about it, and offered to pay for any UNIX admin that
wanted to have the training and for the
MCSE tests.  It took about about 3 months part time, and about 300
UNIX admins got their MCSE.
  In both cases, all these folks were 'paper certified'. ... These
tests basically proved that an certification without
experience is useless in real world applications.  It still gets folks
the job, but that is not enough to keep them
on the payroll.
  Folks that knew how to 'think like an admin' did well with or
without the 'paper'.  The certification just says
that you have the base knowledge, not that you know how to apply it.

Enjoy. ... Jack

[nlug] Re: OT: Online College

[Jack]

Another minor issue I have with Certificates, is they SEEM like just another
$$ mill
for the vendors.  You must keep renewing, taking an additional course or you
loose your
certification every couple of years.

Yes technology keeps changing, but some of these just seem like 'continuing
education', and 'pay us to take our exam again' issues, ... Just keeping the
vendors bottom line
fat, and not necessarially adding value to the recipient or the place the
recipient works.

Probably just my jaded perspective.

[nlug] Google DNS and DNS speed

[Jack]

I was perusing the net and found that Google has
some pubicly available DNS servers.

http://code.google.com/speed/public-dns/docs/intro.html
http://code.google.com/speed/public-dns/docs/using.html

After ping their IPs and my DNS IPs (even 4.2.2.2 ) the ping
times are slower using the google ones.

Even though Google says theirs are faster and non-recursive,
I am not convinced that the total DNS lookup time is faster.

What tool would you use to help determine the faster 'effective speed'
of a DNS server as seen from a remote client?

[nlug] Speech to Text

[Jack]

I am looking for inexpensive appliances that will do speech to text.

My father-in-law has had poor hearing, but was just diagnosed with
a disease that should finish making him profoundly deaf soon.  It is
progressive with no real turning back.

I have played with the lame speech to text built into Vista recently.
It is OK, but not good enough.  My son mentioned applications for
iPodTouch and iPhones.  But I am trying to find more options that
will make my father-in-law not feel isolated in a speaking world.

My FIL is still pretty spry for 80+ but fine motor skills (like texting
or to much typing) are not in his skill set.  He has claimed that much
of his hearing was lost working in Phillips Petroleum Research in the
combustion lab where they ran test gasoline engines without mufflers
(or much other sound safety equipment) for years. ... The lab has
changed now, but it is 40+ years to late, plus we just determined
that it may be partly genetic in his case. ...

My hearing loss is mainly attributed to spending to much time in a
computer center
in College working between high speed printers with the covers up and
running bursting and decollating machines at minimum/slave wages ($1.25/hr)

Any links, leads, or information would be appreciated.

[nlug] Compaq/HP recovery partition - helping others with winders... again

[Jack]

Thank you for your tollerance of non-Nix issues...

I have a friend I am trying to help with a compaq notebook.  The hard drive
developed so many bad sectors it couldn't boot, not even the recovery partition.

We got a set of the HP system recovery CD's and was able to put an OS on
a new disk drive.  But he needs to use the HP/Compaq Recovery Manager to
restore some things from a backup he made a few months ago.

Or at least get a few files from the backup that was made.

THE QUESTION:
1) How to build a 'real' compaq recovery partition with recovery manager on it
so F11 can boot into recovery manager?

2) OR ... Given a backup that was made with the Compaq recovery manager,
how can I get the user files out of the old backup.

Thanks...

><> ... Jack

BTW, the OS is Vista Home Premium, on a Compaq Presario F700 laptop.
   I ask these questions here because my frustration with searching the web
   is becoming apparent even to me! ... JC

In the original post, Howard was venting his frustration that many of us feel.
But he also understands the golden rule...

   He with the gold makes the rule.

That is not a value judgment, just a truism.  I could site many obvious examples
but that is redundant on this list.

Re: [nlug] top posting - bottom posting

Since most of us have 'threading' email readers, why keep the 'old
posts' in your email at all unless you are going to reference quotes
in them?

It is just another waste of bandwidth as is 'Rich formatting' or
whatever your email reader calls 'fancy fonts and formatting'.

Not that we are going to change the world, ... our only solution is to
do what we can with what we have and attempt to influence others.

Re: [nlug] Distro

[Jack]

Sudo can be VERY flexible when properly configured and good security
is done on machines.

In the past I have helped set up machines so some users can do some
things, other users can issue other commands or run scripts, all
dependent on the groups to which they belong.  At least in the past
the sudo configuration was in the /etc/sudoers ...  Things seem to move
and migrate in more recent implementations

su just allows one to become super user (root) and must be done with
the password of root.

sudo allows no one to NEED the root password, even to do admin work.
It also allows for more auditable security.  Everything that someone does
on a machine via sudo can (and arguably should be) logged, so it can be
audited if the need occurs.  If you just su and use the root password,
the last auditable event in the logs is you became root. (the same argument

At one customers site, we (a consulting company I worked for) implemented
sudo on their servers.  WAY to many people had root access and for any number
of reasons talked their way into having it (personal power things, not 'real'
business needs).  It took a while, but we did manage to even implement
procedures so there was a 'root' password, but it was automatically
generated, changed on all the servers, and a procedure was in place to
print it in a way that no one saw it, and it was put into a envelope in the
data center managers private office.  It was available to anyone who wanted
it, and could justify it to the DC manager.  If it was used, the procedure was
to have a new one generated and implemented the next business day, and
an incident report was filled out by the people who 'justified' the need for
the password.  That was taken and reviewed to put new procedures in place
so it was not needed in the future.  It didn't take long till there were almost
no 'need' for anyone to have the root password.  Also the password was
changed once a quarter 'for good measure'. -- Yes we were anal about it,
but the user management wanted solid and auditable security, so they got it.

Good?  Bad? It all depends on your needs and where/what you are doing.

Re: [nlug] Powerline ethernet

I used it a little in the past.  Not bad but not good either.  I tend to

Yep, Robert had the right answer.  The initial install needed another

The 'tin can and a string' network we have is not what we could

[nlug] Re: Speed on eeePC 900 with Ubuntu

[Jack Coats]

I agree there are only so much you can do by kernel/os tweaking.  
Applications design and picking
the right light weight apps can get get that speed.  Even application 
tweaking has its limits.


There was a M$ Windows type interface that worked very well on old 286's 
when M$ was pushing 386 as a minimum system.  It was written fully by 
hand in assembly, while M$ windows was C++.  And it was screaming fast 
and reliable.  But no one seemed to care.  "Hardware is cheap" was the 
motto that killed them. But there is always a place
for good, well designed software.  It just may not be where we think it is.

[nlug] getty problem

[Jack Coats]

Ok, I have a problem.

I can't find what is happening to my mgetty process, it keeps dying on a 
'random' basis.

/var/log/messages has messages like:
mgetty [proc#]: init chat failed, exiting...: Interrupted system call
  failed in mg_init_data, dev ttyS0, pid:...

these are folks using ssh from windows machines logging into a Centos 
box to run a 'green screen'
program.

Some users die, while others keep running.  When the user dies, they 
leave an attached application
process running (a basix program) that must be killed by the admin 
before a user can log in again
from that client.

Suggestions?  Or a place to suggest for me to RTFM?

TIA, Jack

[nlug] Re: Meeting Nov 11

[Jack Coats]

Just a suggestion, if more folks would do presentations on Linux, then 
there would be more
presentations on Linux.  I was president of another group elsewhere, and 
I can attest it is very
difficult to find a continuing set of original topics and speakers.

Anytime someone want to talk on any subject it is a breath of fresh air 
to the organizers.

So if anyone wants to do a presentation on Linux or most related FLOSS 
subjects, I am sure
it will be warmly received.  Personally, even a proprietary application 
that interacts or relates
would be acceptable.  Thinking Netapp, Cisco, or other hardware or 
utility software, etc. would
be of interest, just not a steady diet, and keep the sales droids to 5 
minutes, but let their techies
ramble!

Other related topics could be: the impact of Linux and FLOSS on products 
and product
development, OR on the new re-rising 'maker culture', OR on society in 
general and how it helps
or hinders.  Just some ideas that I am NOT qualified to speak about!

[nlug] Re: Geographic Domain Name Registration?

[Jack Coats]

I found the registrar, and downloaded the form, filled it out, and 
emailed it in. ... it took a couple of weeks,
since he did it by hand. ... this was some time ago.  I had to give them 
all the same information we do today,
just like getting my coats.org domain back when there was only one 
registrar for .org's

You are right, STATE.TN.US is reserved for each state, and using just 
.US is not allowed.
But evencity.XX.us is valid where city is the city name and XX was 
the state.  There is also the .aero domain
that is limited to the aeronautics industry (at least it used to be).

I think I still have coats.houston.tx.us but it is 'legal' to have 
domainname.XX.us if you can get your registrar
to grant it.

Thus goes my search.  I sent an email to the person who is the contact 
for the STATE.TN.US domain asking
who the registrar is for tn.us but have not received a reply.

... I just checked, yep, coats.houston.tx.us is still there ... I wonder 
what it points to now :) ... another task to deal with.

... now ... aren't you sorry you asked :) ... Jack

[nlug] Regional Domain Names --- definitive answer

[Jack Coats]

I finally got to the registrar for tn.us, and yes, anything under tn.us 
is NOW for governmental
or government agency use only.  I do have links to the forms in case 
someone wants to tilt at
that windmill!

The .us domain is a free for all as are other commercial domains at your 
friendly neighborhood registrar.
Godaddy seems to charge a premium for them for some odd reason.

... Thanks for the input. .. Jack

Only if you install the Flux Capacitor in your Tardis ;)

... Even Einstein didn't call E=MC**@ a law, just a good approximation 
of what he could determine.
And to that extent the string theorists have proven that Einstein was 
wright, in that his statement was wrong,
at least around the 'edges', but it, likes Newton's 'laws', are good 
within their defined domain.  Things tend
to brake down at the 'edges' and when boundry conditions that need new 
understandings happen.

I am guessing we will find the same with Moore's Law.  Do we really need 
transistors?  Yep, flux capacitors
could be the next 'big thing' so we can re-start discussing Moore's law, 
Global Warming, Global Cooling and all the
'important topics' of the day!

[Jack Coats]

Gosh, the Russians were doing base 3 in the 1970's (better because it 
was closer to the base e, and
they figured out how to do tri-state devices with discrete transistor 
technology), and it worked,
and bi-quinary was even used on the console displays some old IBM 
boxen.  I think it was
the 1620, and it ONLY did decimal math.  Kind of the 'scientific' cousin 
of the IBM 1401.
...At least it wasn't a punch card only machine.  One of the versions of 
the IBM 360 used air bags
pushing against aluminum foil with punch cards between that and other 
metal strips, and used that
as its 'changeable microcode.   And it was Burrows that brought out 
magneto constrictive
delay lines as memory. ...  In college we had a CDC machine we had to 
repair, using discrete
germanium transistors on 2x2" printed circuit cards.  4 transistors and 
two flip-flops on each.
Yea, it took up a room and used 7 track, 256bpi tape drives, and had 8 
of them and no disk.
It paged off of tape.  It ran FORTRAN 2 pretty well.  But the COBOL 
compiler was REALLY
slow.  Assembler on it was fun though.  You should have seen it run a 
big balanced sort using the
tape rives!  It did a cameo in the movie "Colossus: the Forbin Project".

To bad you all missed all the advanced technology!

[nlug] Re: You just have to love math...

[Jack Coats]

The CDC 1604 was funny.  The OS tape had the OS and compilers on it.  
When you gen'ed a new
OS, it wrote multiple copieis of the OS and compilers and libraries onto 
the same tape.  If it needed
a file, it would spin to locate the file in the shortest amount of time, 
front or backward.

Yea, with 32K (or was it 64K) of 48bit words (most instructions were 
half word), if you wern't a good programmer
the thing could thrash.  We also did overlays to help keep from having 
big programs take over
all memory.  Architected right it was quite efficient.  But then again, 
these mainframes are dwarfed
by the CPU power (not IO) in a Blackberry, iPhone, or any current laptop.

The computer also had a speaker attached across the 'A register', kind 
of a crude Digital to Analog interface.
The computer would play different notes/tunes if it was waiting on a 
tape mount, or a response on
the IBM keyslinger typewriter it used as a console. ... The 'boot ROM' 
was really on a 64 step
stepping relay (what a racket it made).  And the console had a built in 
high-speed paper tape reader
and punch. ... how technology has moved on.

Glad you enjoyed it.  I wish I had films of it!

Before I left college, the Navy (who gave them the computer, it was old 
then), gave them a disk drive.
It was 6' high, and platters were 3' in diameter.  There were two 
read/write arms, on different corners
of the clear drive cabinet.  The would come out, then move up or down to 
the right platter, then swing
in to do the read/write.  I saw it work but had moved on to do other 
stuff by then.  Still, Rube Goldberg
(check wikipadia if you don't know the reference) would be proud.

Every once in a great while, the logic still come to bear.   Doing 
topological sorts still has uses
in determining what should come first if there are options in a directed 
tree.  I have had to use
it in some systems modeling applications.

The museum in Boston I went to (I assume it is still there), was great.  
It too had an ENIAC frame,

the 1 leg running robot
that ran in a circle.

Burroughs had some funky metal 'wire' that would do that, without being 
a tube of mercury.  It was the
'magneto constrictive delayed propagation memory' or some such milarky.  
Basically a magnetic pulse
'squeezed' on end of the 'wire' and the magnetic 'wave' propagated down 
this 'metal' until a coil on the
other end 'read' the pulse.  It was used as a 'long' shift register, 
where if the memory was to be retained,
it had to be 'written' again into the 'wire'.  This was before the days 
of 'cheap core memory', just trying
another technology.  High cost technology allows for some strange 
competing ideas.

Simple Backup in the Ubuntu repository is worth looking into.  
Especially if it is just a machine or a few
you want to backup.
Check out BackupPC ... it does rsync nicely, especially if you run 
multiple similar machines the
non-redundant storage (due to hard links on the backup server) is good.

You might snag a copy of the Riley's UNIX Backup book by Curtis Preston 
(and a few more).  I was working
with him when he wrote the first edition.  It has several reviews and 
DIY scripts available
there and on his old backupcentral.com web site.  Since he sold out, it 
might have moved.
If this is for a big $$ company, hire Curtis for a consulting gig, and 
tell him I sent you.
I think he is still in Calif, but that was years ago.

Barbed wire at 300 Baud? ... Slow is a relative term.  It will work over 
'anything', but slower takes
longer.  If you do it over an encrypted link over a ISDN or dialup line, 
backing up anything
of significant size will talke a long time.

My link is only about 150kbps, and doing online backups is not an option 
for more than a few
critical and control files.  I on occasion use drbackup.net ... But it 
does work.

I have used a vpn over it, and response is 'slow' for full remote 
desktop sessions to be kind.
And at my house we have 3 to 5 computers using it concurrently on 
occasion.  My wife and
I are the 'standard load'.  I download software, she e-mails spread 
sheets and pictures.
This little sprint wireless connection gets a workout.

Whats slow?  2400 baud was great when I came from a 110baud tty.  Now,

T1 is slow after having 100MBit and 1GBit to their dorm rooms.

As Einstein conjectured, ... It is all relative.

Tapes for working data etc were the technology of the day.  Archival, 
working and temp storage,
even bringing in bits of programs (overlays) from tape was not that 
unusual.  As hardware has
gotten cheaper, we throw that at a problem rather than brain cells, and 
tell ourselves we are thinking
at a 'higher level' just because we obfuscate the solution from the 
hardware and ourselves.  For
some problems it works.  For others it doesn't and just gets in the way 
of thinking to a
workable solution. ... ahh, but that is pontificating for another day. ...

[nlug] Re: You just have to love math...

[Jack Coats]

Nothing to defend.  Economics drives development in hardware and 
software.  The cost of
people power has increased.  It just makes $$ to throw hardware at it.

Yea, it took more planning even down to the bit and byte packing some 
times, to get the most
machine effective layout for data structures.  Using stacks and heaps 
for memory allocation were
made a lot easier as the cost of disk them memory dropped (a bit of core 
storage cost $0.10
each and you HAD to have parity.   My first mainframe had 512K of 'fast' 
core, at 100ns,
and a huge 2M of 'slow core' at 250ns.  And with core, when you did a 
read, the hardware
would re-write the data and took 2 cycles to accomplish a read, where a 
write to core only
took one write cycle.  Core had a 'destructive read', as it inverted the 
data whenever it was read.)
Even a 'big' 12" platter type disk drive with 12 platters per spindle 
could only hold 20G, and
mag tape was either 7track at either 256BPI or 512BPI, or 9track at 1200 
or 2400BIP.
Eventually 9 track came to 6250BPI with only a half inch inter-block 
gap.  Prior versions
used 3/4" inter-block gap. ... With those kind of densities it took 
several 2400' (large, 12" reels)
to back up a 20M disk drive!.

Ugh, I have been trying to forget that for years.  I guess I never will 
now. ... Fast drives had
vacuum columns to provide proper tape tensioning over the read/write 
heads and to get it put
on the reels with the correct tension.  Cheaper / slower drives used 
mechanical arms to deal with it.

Using virtual memory, and faster processors/memory changed the face of 
computing.  Reduction
in size has done it again.  Every time the pundits come up with a new 
'wall' for Moore's Law,
something comes up to 'extend the life for a little while longer'.  
Silicon won over germanium,
something will eventually win over silicon.direct write will change.

It has been wonderful to see all the changes that occurred in my working 
lifetime, some expected,
many not.  I hope to be around to see the next 35+ years of change!

[nlug] Re: You just have to love math...

[Jack Coats]

I agree Andy.  One time I was doing some significant logic and due to 
its nature it was very obfuscated.
In line, I put comments in to fully explain what I did in that 20 lines 
of code.  It took about 20 pages of
documentation. ... I figured without it, there would be no possibility 
of maintenance by almost anyone
once the code hit production.  ... Those 20 lines took me a couple of 
weeks to write and test, but it was
called over and over again and was at the heart of doing some 
complicated tax modeling for a Fortune 500
company.

Most code is not like that, thankfully.  Some languages are more 
'readable' than others (even 'readable
languages' can be written in an obtuse manner to make them impermeable 
to most minds).  Even in the
best languages, and the best programmers, writing readable code and 
properly documenting it is not an
easy thing to do.

For me, the OO craze has made it worse, but I was raised on assembler, 
Fortran, PL/I, etc (Yes I did
some COBOL, RPG, SNOBOL, BASIC of various dialects, and a very tiny bit 
of APL and LISP).
OO is not inherently bad, it just made a hard task more difficult, 
IMHO.  Others obviously disagree
and since they are writing and maintaining it, I will not quibble over 
that point.

In any language and method, efficient code is desirable, maintainable is 
better.  On occasion efficient must
override maintainable, but the amount of GOOD documentation goes up 
exponentially if it is to be maintainable.

[nlug] Working system went brain dead?

[Jack Coats]

I have an old iPaq desktop with legacy ports that was working.  I shut 
it down one day gracefully, and tried
starting it the next morning, and it is not generating any video output, 
and it gives a short beep
followed by a long beep. 

I have tried to find what it means, and have pulled out the memory cards 
and re-set them, with
the same results.

Suggestions? (Cash flow precludes replacement at this point.)


... Jack


(Why that machine?  It is small and has legacy ports, and has enough CPU 
power
- 1GHz with 512M memory and 20G hard drive - to do what I need it to do.
Running Ubuntu on it.)

I guess I should crack the case and get to the mobo, to see if I can 
find any capacitors that
let out the 'magic smoke'.  I haven't smelled anything like burned

happened.

Wally World also teach locals how to compete and win against them, even 
before they enter
a market.  Basically, don't compete on price, you will loose. Compete on 
support, service,
extras received, support after the sale, just not on base price.

I am not giving them a halo or anything, but being the 500 lb element in 
the room, any move
they make is amplified in its effect.

It was the next step up from a Monitor but definitely below being an

[nlug] Re: DSL: Is it worth switching?

[Jack Coats]

I agree, that for the most part, cable companies have not figured out 
that 2-way communications means consistent availability.  AT&T has been 
known to forget that (The great Lilly Tomlin operator skits were based 
more on perceived reality from many peoples experience than fiction.) 
from time to time.

To bad that where I live, dialup modems are still limited to 28.8, there 
is no DSL available, and no cable.
The satellite I tried (wild blue) had such propagation delay (think 
2,500 millisecond ping times - our satellite was routed via a downlink 
station in upstate NewYork, then routed on AT&T lines to Colorado where 
WildBlue was based - so far 14 router hops, before being dropped onto 
the open internet in mid-state Colorado somewhere - FTP speed was OK, 
but half the time I couldn't do interactive banking with my local bank). 
Currently we get about the same speed using Sprint Wireless, but the 
latency makes it reasonable.  It is still only half the speed needed to 
make hulu.com work for me.  Who know, one day I may be able to get 20th 
century data speeds before the 21st century is up or I die. -- Sorry for 
the whining.

Over time, the phone company has learned that making service appear 
consistent is a better business model for them than making it as good as 
it can get everywhere.  So I don't expect much if any more 'good 
mediocrity' from them.

Cable companies seem to still think that 90+% uptime is reasonable, and 
it may be for broadcast communications, but bi-directional 
communications, you will get folks to complain when you get less than 
5-9's reliability (I think that is about 56 seconds per year of 
unscheduled downtime to put it in perspective).

As bad as Lilly made the phone company sound, it is still a better game 
than cable for interactive service, IMHO.

[nlug] Re: Bandwidth monitoring / limiting

[Jack Coats]

I used to use WildBlue.  Their 'Commercial Package' was about twice the
price of the 'home', but it was worth it, in that I got a much larger 'fair
share'.  My issue was not the speed, but propigation delay (think 1500ms
each way! ... comapare to 'surfing' at 28.8 as a top speed)

We went to 'Sprint Wireless' and are getting about the same 'speed' but much
lower propigation delay.

If your friend can get it, I suggest that over Satellite.

I used to use a caching web and DNS proxy using SQUID on an old linux 386
machine back in the day.  It worked well and also doubled as a local mail
server and web host for 'in home' web pages.

My best to your friend. ... Jack

[nlug] Re: Looking for the unlikely "consumer grade" product

[Jack Coats]

I think you are on the right track.  For the billing rate, it is
probably cheaper to use 2 wifi routers and
a third router, or router with no wifi enabled than anything else.

Just on a lark, take your DSL, hook it into a cheapie 4 port
hub/switch, and plug the 'wan' side of
your current routers into it.  You might be able to get away
depeinding on if the DSL provider will
give you 2 ip's.

[nlug] mythtv again

[Jack Coats]

I know others out there are using MythTV.  Being lazy at heart, I plugged in my
HDTV HD-3000 tuner card into a machine I was given (faster than any
others I own,
with 1.8GHz), And downloaded mythbuntu and installed it.  Display is an
nVidea card that was in the Gateway machine I was given.  Only 748M memory
but I can fix that if this thing will run at all under its own weight.

Needless to say it was a flop.

Looking at the logs, the HD-3000 card shows up, but I can't seem to get
Mythbuntu to recognize the card.

Then I put in a DVD, that I wanted HD to 'rip' to disk.  The transode
function seemed to work, but it doesn't show up in the 'library'.

If someone can suggest a different 'pre-installed' MythTV, I would not
mind giving that a shot.  Or something else to assist.

Suggestions welcome. .. To keep un-interesting to others traffic down
I may be directly off list.  I will post any 'interesting' updates.

[nlug] Re: mythtv again

[Jack Coats]

Not a problem.  I'll gladly share the wealth of any reasonable 'howto' I can
develop.

I found this HD Tuner card, the HD-3000 just before I moved to TN and
ordered it.
The other projects, like moving, got in the way of using it.  I found
a 'cheap' Polaroid
DVR, but it has problems and will be basically useless after things go
to HD only broadcast.

That means I have a 'need' rather than a 'want' now.  The Polaroid (I
got through Woot 2 years ago)
has spoiled me.

I am trying to get an 'appliance build' rather than 'roll my own' just
to keep down
the re-development issues that come with the 'propeller head'
installs.  I'm not against
them, but my frustration builds to quickly.

After some more research my HD-3000 has a good rep with mythTV folks.
But the last incarnation
of either myth or mythbuntu 'broke' the HD-3000 useage.

I have now tried mythbuntu (I like ubuntu due to it's close to
'appliance' install that just works, for me anyway).
Now to go find some others.  I have seen info on Mythdora and Knopmyth
... we'll see what sticks!

[nlug] Re: Building a NAS

[Jack Coats]

For reliability sake...

You might consider two drives and mirror them for your 'system' drives,
where the
NAS client data would be on the raid.  If you go with a hardware raid
controller
that is off MOBO, consider one that will allow raid6, if your budget
allows.  This way
Murphy is less likely to win.  Also, power supplies that allow TWO separate
feeds.
Plug each into separate UPSes, or at least one into a UPS and the second
into
wall (but surge protected) power separate from the UPS.

Yes, the dual feed power supplies are out there, I have used them, but
typically ordered as
part of a 'server' setup.

Since I did mention it above, yes, UPS is important, along with making sure
you
monitor it with appropriate software.

Consider extra temperature controlled fans too.

Redundancy even in the ancillary portions of systems help up the reliability
of the
entire package. ... Just the dual power feed we found important even in a
computer
room because 'tours' (management done, not by techies) cause plugs to be
'accidentally'
kicked and server power removed.  The same for serial, ethernet, and fiber
cables.

Sometimes you can get find power plug holders, both for the plug end and the
power supply end.

[nlug] Re: Data security?

[Jack Coats]

I agree with Sky.  There used to be 'low level format' available on cheap
IDE controllers that worked pretty well.

The best I remember seeing that kept the drive useable was an old
dos/windows program that did a 'distructive disk test'
that I used several times on different disks that were otherwise
un-recoverable anyway.  I wish I could remember its name.

You could build a small sh script to use dd to write some pattern till it
filled up a drive using different patterns on various passes,
but that is kind of a pain.  If you are discarding a UNIX derivative, just
do a fresh install with a different type of file system.

A good way to physically demolish one is to take it to your local
neighborhood blacksmith (I had one across the street when
I lived in Houston) and go with him to his forge.  Melt the drive to a nice
pool of silicon and aluminum sludge.  It is very satisfying.
It is really hard to recover data after that.

Pouring the sludge into a nice paper weight, door stop, etc is also fun.

 ... Actually a good coal fired BBQ of old disk drives behind the HC one
weekend could be a nice community support project! :) ... Then cast them
into trophies for 'worst security' to be handed out to folks at the next

[Jack Coats]

Johnothan,

 A few days before the next NLUG meeting, you can send out
a message and there are several certifiers in the group that could get you
the credentials you need so you can get enough points to (1) certify others,
and (2) get all the certs you want yourself from CACert.

Make sure and bring the paperwork and your identification (according to the
cacert.org web site).

The same goes for anyone else that would like the ability or
certification...

[nlug] Re: Suggestions or ideas on running a CA

[Jack Coats]

Since I KNOW I DON"T KNOW, how about someone that really understands and
uses
certificates (especially from CAcert) do a NLUG presentation about them?
Everything
from 'why use them', 'differences in certs and keys', 'how to make them'
(server uses of
various kinds, client certs, etc), 'how to use them' (again each kind), and
have a quick
'certification party' afterwords, where we could also do key signing.

Yes, covering keys, signing and use would be another great side topic,
especially
if we have a related key signing party.

Just a thought.

Actually, having an annual 'cert/key' event would be a 'good thing'(tm).

Just some thoughts. ... Jack

Try setting your router for another channel that is less used.  That way you

chicken wire in them.
Ground the chicken wire.  Now it keeps your RF inside, and their outside :)

[nlug] Re: Crowded wifi space

[Jack Coats]

Yep, we live in an old house provided by my wifes employer, so we have some
of the same issue.
We have found Sprint Wireless connection to work pretty well for us.  No
cable or DSL available here,
and less latency than satellite (we tried WildBlue for some time, think
2500milliseconds latency ... ugh).

If you have a tennants association, you might bring it up and offer to be
their 'tech-geek-in-residence' for
WIFI.  Reducing strength on signals may sound odd, but you could actually
get everyone better response
and fewer retries.  Or consider getting the landlord or tennants association
to offer 'free wifi' for tennants
who want it and 'agree to play nicely together'. ... Just some thoughts.

Lots of luck.
