[vox-tech] SOLVED - Re: Linux live disk's install attempt onto external drive botched my internal drive's grub!
Ok, the solution was easy. From the "grub rescue>" prompt, I had to poke around to see what was what, and where. My laptop's /boot partition was coming up as "(hd0,msdos1)", and when I did an "ls (hd0,msdos1)", I saw things like: grub/ memtest86+.bin ... vmlinuz-3.13.0-51-generic initrd.img-3.13.0-51-generic ... So all I had to do at that point was tell grub how to boot: set root=(hd0,msdos1) set prefix=(hd0,msdos1)/grub insmod normal insmod linux linux (hd0,msdos1)/vmlinuz-3.13.0-51-generic initrd (hd0,msdos1)/initrd.img-3.13.0-51-generic boot A bunch of kernel boot-up noise appeared, and I was prompted to enter the passphrase to decrypt my root (/) directory, and after a moment, my KDE login screen appeared! I brought up a shell, and run "sudo grub-install /dev/sda" (notice, not "/dev/sda1"). Rebooted, and here I am. Whew! Thanks very much to my coworkers (and sometimes LUGOD visitors) Case & Dmitriy.

[vox-tech] Linux live disk's install attempt onto external drive botched my internal drive's grub!
So we got a new SSD drive for Melissa's laptop, and I've placed a Kubuntu installer/live demo image onto a USB flash drive. Melissa was busy working on her laptop, so I decided to just get the install onto the new SSD, and we can physically migrate drives between her laptop at our leisure. So, I booted _my_ laptop up with the installer USB flash drive, and stuck the target drive for the install (the SSD drive) into an external SATA enclosure, and connected that to my laptop via its USB cable. Then I told the installer to install onto that external drive. I answered a few questions, watched the enclosure's blue LED blink at me for 10 minutes while the installer did its job, and done! "Great," I assume! I unplug the installer USB flash drive, and try to boot up the freshly-installed Linux off of the external drive enclosure. It didn't come up. That's not good, but not a disaster. But, it gets worse... So I unplug the SATA enclosure's USB cable as well, and reboot my laptop again. Now I'm staring at a "grub rescue>" menu!

[vox-tech] Change to vox-tech list moderation
This, LUGOD's "vox-tech" technical discussion mailing list, has for a very long
time now had the following administrative options set:
* Action to take for postings from non-members for which no explicit
action is defined.
(Details for generic_nonmember_action)
+ DISCARD
* Should messages from non-members, which are automatically
discarded, be forwarded to the list moderator?
(Edit forward_auto_discards)
+ YES
This way, when someone who has a legitimate reason to post a message to
the list has their post discarded, since they attempted to send from
a non-subscribed address (e.g., sent from address A, when they're actually
subscribed to the list under address B), I would notice it, and forward it
along to the list for them manually.
I did not bother having posts held ("HOLD" option, vs "DISCARD"), since it
was a very rare occurrence. These days, since the mailing list volume is
extremely low (but the spammers still try sending messages to the list
address), almost ALL discarded messages are junk, and it's kind of mind
numbing and tedious (and a waste of my time) to have to go through them,
_just in case_ someone posted from a bad address.
I've decided (with no objection from other officers) to completely ignore
such messages, by setting that second option to "NO". It'll make for a much
quieter inbox for me. Further, if someone tries to post to the list, and
it never shows up, I figure it's really up to them to figure out that they
did something wrong (when it didn't show up, if they get their own posts,
and/or when they never receive a response from other subscribers to the list).
Thanks,

[vox-tech] Seeking recommendation: USB or low-profile PCI WiFi adapter
We received a second-hand desktop PC (I know, right!?) that we've set up for my older son to use. We recently moved it far, far away from our home office, and I don't want to even contemplate wiring up Ethernet across the house for it. It's a Small Form Factor (SFF) Dell Optiplex 745, and IIRC has one low-profile PCI Express slot available right now.

Re: [vox-tech] Synaptics driver problem on Lenovo Thinkpad e455
I dont have the laptop in front of me, but over on: https://wiki.archlinux.org/index.php/Lenovo_Thinkpad_Edge_E455 I see: ClickPad The clickpad that is used is from Alps. Specifically, it uses Alps protocol 8 which has initial support in kernel 4.1. While basic functionality works with kernels less than 4.1, there may be issues that occur with use in kernel less than 4.1. For more advance features such as Vertical Edge Scrolling, see Touchpad Synaptics. An interesting quirk that occurs is that in order to be able to use Vertical, or Horizontal, Edge Scrolling you have to enable Two Finger Scrolling. Setting only the Edge Scrolling option in xorg doesn't enable it. And: http://www.ubuntu.com/certification/hardware/201407-15368/ lists: Unknown SynPS/2 Synaptics TouchPad Trying to remember 2 months ago, I recall being able to either disable the whole PS/2 mouse system (which disabled the TrackPoint, too), or enable everything.

Thanks in advance! Does lsmod say any synaptics kernel modules are already loaded? Assuming it is referring to the kernel module and not some separate X Windows driver, it might help to load one of synaptics_usb or synaptics_i2c, maybe before X starts? The usual place to put kernel modules to be loaded for no apparent reason is /etc/modules.

I'm done stabbing in the dark, using recommended tips that are probably useless nowadays. The main issue is an inability to type on the thing, w/o the mouse flying all over the screen. (There are all sorts of great settings to disable touchpad when typing, or when it detects a palm vs. fingers... none of which are available to us until we figure out this driver problem.)

Re: [vox-tech] KDE on Debian
Is this KDE 4? If so, try right-clicking the panel. (If you see Unlock widgets, click that. Then right-click the panel again.) Select Add Widget. Scroll until you find Task Manager (or type task into the search field and it'll filter out everything but the widgets with task in their name). Click Task Manager and drag it into the panel, or just double-click it. If you need to reposition it, click the 'cashew' icon (as people call it) on the panel (probably at the far right). Hover over the task manager widget. Click and drag to move. (You'll probably see a 4-directional plus-shaped arrow.) You'll also see [wrench] Task Manager [x], which allows you to change the task manager's settings, or remove it. (You can also do these actions by simply right-clicking in an empty part of the task manager, though sometimes that can be difficult... hence my mentioning the cashew trick.) Good luck! -bill!

The problem with todays environment is that there is real-executables,

uses functions (which can take arguments, etc).
But in the end, there are in fact 3 places to look for a definition. So

declare -f $prog

Which if you use in replace of `which` checks all three sources and
reports the definition or location to you.

# wh wh
wh ()

Subject: Implementing interrupt handlers
To: vox-tech@lists.lugod.org
Hi everyone, let's see if you can help me.
I'm trying to implement my own interrupt handler (why? because it's fun
:). My idea right now is to install on the system a function like
system_call() (you know, the handler of int $0x80), but on a free
interrupt.
First I tried by using the kernel function request_irq(), but when I look
at the corresponding IDT entry there still was the ignore_int() function
(you know, Linux sets all the interrupt handlers as ignore_int() and then
it fills the handlers properly with ?init_traps()?). Am I wrong or should
request_irq() write on IDT?.
After failing with request_irq() I decided to write the changes on IDT by
my own, so right now the changes on IDT are made by me (using a bit of
kernel's help):
/***
* @n: The index on the IDT that should be rewritten.
* @addr: The address of the new interrupt handler.
*/
void setGate(unsigned int n, unsigned long addr) {
gate_desc entry, *idt;
struct desc_ptr idtr;
// Code extracted from arch/x86/include/asm/desc.h, I prefer to have
the
// same notation.
entry.a = (__KERNEL_CS 16) | (addr 0x);
entry.b = (addr 0x) |
((0x80 | (RING3 5) | GATE_TRAP) 8) |
0x00;
native_store_idt(idtr);
idt = (gate_desc *)idtr.address;
native_write_idt_entry(idt, n, entry);
}
Here we have not the includes and defines needed but it is not hard to
guess them (asm/desc.h, asm/desc_defs.h, define RING3 (3) if I still
remember...).
When I do it by my own the IDT is correctly rewritten but when i try to
call that interrupt from user space context i got an error. Here you have
the stupid program that generates the interrupt:
.globl main
main:
int $n
nop
Where n is the vector of the interrupt I rewrote, usually interrupt 31.
When I run this program the task got killed and the kernel wrote this
message into /var/log/messages:

Re: [vox-tech] CalDAV
It's super-funky homebrew php.

I would not design it that way if I were to start again. :) The ical files are actually produced by the webservedr, via a links -dump invocation from within a Makefile. Yes, insane! I know! But it works I have had almost no reason to change it ;) We have a web maint. how-to floating around somewhere (apologies; emailing via cellphone from a toy store :) ) which explains a litlte of this.

Quoting Bruce Coston (jane_ik...@yahoo.com): I need to get a distro on one of my many small-ish laptop partitions that will play back YouTube videos I suck at the library after I suspend to disk and go home during our many summer Internet outages. My elive install suffers real problems with this, after I take it off disk suspend, back home. Bruce -- I'm going to make a longer post on this subject that aims to be more comprehensive, but here's the short version: You're relying on local cache state of the Adobe Flash interpreter being useful and complete after suspend to disk. Bad strategy. Instead, install scripts or browser extensions to download the clips to local disk. Slight elaboration: I'm assuming Flash (Sorenson H.263 encoding in FLV container) for the sake of discussion, though Google's YouTube service also offers video in MPEG Licensing Authority's patent-problematic H.264 encoding in either FLV or MP4 (MPEG-4 Part 14) containers (often inaccurately called 'HTML5' video), in Google's (ex-On2) VP8 encoding in WebM containers (which along with Vorbis encoding in a Matroshka container is part of the HTML5 draft), and in MPEG-4 Visual encoding in 3GP containers (a format primarily intended for mobile 'phones). It's pretty much the same problem regardless. Why a problem? Your media player plugin (Adobe Flash, for the sake of discussion) is streaming-in the inbound A/V bitstream and dumping it into ~/.mozilla/firefox/[hash]/Cache on an ongoing basis, but that cached copy isn't guaranteed complete and useful at any given moment. Also, it's not the least bit surprising to hear that Adobe Flash acts stunned and stupid if it suddenly wakes up after being suspended to disk. So, no, you're actually lucky if that ever works, because you can be sure that the buggy spaghetti code in question isn't designed to do it. So, let's say you look at the page HTML on a YouTube page to try to find the .flv direct link so you can pull a copy down using wget or curl. Surprise, you can't find it. Why not? Because you are not Google's customer; you are their product -- and they are far, far more eager to make Our Lords in Hollywood happy than they are you. So, they cause YouTube to wrap the .flv link in inscrutable JavaScript, in order to make it difficult to puzzle out. Moreover, they gratuitously change that JavaScript obfuscation occasionally, to screw people up who've de-obscured the latest version and are letting others know how. (They do that because Our Lords in Hollywood don't want users to have local copies that cannot be retroactively withdrawn from availability.) Nonetheless, there are folks who gamely keep up with the changes, and you can should benefit from their work: clive (Perl script) cclive (newer C++ rewrite of clive) youtube-dl (Python script) Flash Video Downloader (Firefox extension) Easy YouTube Downloader (Firefox extension) Get 'em all. There are distro packages for clive, cclive, youtube-dl (judging by Debian). You may find the distro packages' frequency of update adequate to keep up with JavaScript mischief at YouTube, Photobucket, Dailymotion, Metacafe, Facebook, Yahoo, depositfiles.com, etc. -- or not. If not, you might need to have them as locally installed and updated software. ALSO: There's a persistent misconception, spread about by the ill-informed, that the open source Flash interpreters (Gnash, Swfdec, and GPLFlash) are inadequate to handle the Flash served by YouTube. No, wrong. It's really just the obfuscatory JavaScript.[1] Which, if you use a downloader such as those listed above, and it works, suddenly becomes a non-problem. So, in addition to the recommendations above, please consider losing the Adobe Flash proprietary garbage, or at least using Gnash in preference. (For one thing, the Gnash developers don't spy on users, about which please see http://lwn.net/Articles/129729/.) [1] Adobe consistently withheld Flash's technical specifications from the open source community, making selected details available only under restrictive agreements. Starting June 2009, in the face of mounting competition from alternatives (H.264 in MP4, VP8 in WebM, Vorbis in Matroshka, and especially Microsoft Silverlight), they finally coughed up the SWF file format specification without restriction, but omitted anything about the key Real Time Messaging Protocol (RTMP) and Sorenson

Brief follow-up. I'm using Intel video drivers from http://ppa.launchpad.net/glasen/intel-driver/ubuntu I used those after upgrading Ubuntu 10.10 from KDE 4.5 (which it comes with) to KDE 4.6 (and now 4.6.1), which was made available from http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu I had to do so on my Dell 1525, as well as my wife's Thinkpad X41, because after upgrading to KDE 4.6, the screen wasn't refreshing properly. Anyway, over the course of the past few months, those drivers have been updated a handful of times, and I checked my S-Video out again recently, and there's magically been a little progress. Now, instead of my TV-1 display being unselectable in, for example, KRandRTray, it now shows up as a connected device when I have the S-Video cable plugged in, and the TV turned on. However, no progress beyond that, so far... my TV remains black. :^/ I haven't had much time to care about or work on this, but I figured I'd give an update with the progress, rather than just leave the thread dangling. -bill!

I am wondering if I can get some help with building a custom Linux distro from scratch with the kernel, libc, gcc, and busybox. Busybox doesn't have to be a requirement. If I can get the C library compiled, I'm sure I can compile every other program for it. The target is x86. I've looked at guides online and even attempted the Linux From Scratch, but I'm having a hard time with 1) the initramfs as my compiled kernel (version 2.6) would boot but unable to load the initramfs and 2) the kernel config has way too many options and I don't know what I can leave out. I don't need a lot of the built in drivers, just the standard ones for USB, VGA, etc.. and Broadcom and Realtek wireless drivers. If the kernel doesn't have it by default, I have the source so I can compile it in but I don't know how exactly. This may require a one on one session of sorts as I don't think email can suffice. I hear there are installfests and events that may provide such opportunities or if anyone in Davis wouldn't mind swinging by campus every once and a while, I have the target hardware and office space to work from.

First, you have to realize that the computer parts industry feels that a 5% defect rate is good. Which means that some cheesy computer companies think that 10% is good. They figure that you're all technically minded and that if something goes wrong, you'll figure it out and return it. That being said, I'm not sure what the number is, but I'm sure that its something in the 10-25% range where some products, especially USB, Firewire, power supplies, IDE, and SATA buses are out of spec. Not enough so that they don't work on their own. But enough so that if you have two out of spec controllers in one computer, and they're off on their timing, voltage, etc it will crash. And sometimes not crash consistently. Sometimes its something silly like putting on an IDE drive on the same controller thats running SATA. You never know. Ok, so before you get scared here's how you start. You start by setting up a bare bones system. The minimal. Motherboard, RAM, Processor, Case/PS, CD Drive, and HD. That way you know whats working before you start adding all the other stuff. Let the BIOS help you out before you even start loading on the OS. Make sure there are no errors. If there are, it will be easier now than when you have everything else loaded. Load the OS. Then the other devices on one at a time. Certain symptoms scream that things are wrong with particular devices. Sparkly screen.. probably the power supply, display card, or driver. Keep loosing a hard drive.. incompatible hard drive, or conflict with the bus its on. Lots of times, it can also be driver errors. Stuff like that. Somebody else here mentioned that they swap parts out and that is really your best bet in finding a problem once you suspect which component is causing it. HOWEVER... nowdays there's so many things integrated into the motherboard its getting harder to tell when thats on the fritz. And it can be only one part that went bad. Like the clock, or something stupid like the keyboard controller. Good luck on the hunt! I myself just had a problem with one of my SATA drive that kept disappearing. After a lot of switching around, I figured it to be an incompatibility with the controller, another drive that was attached, or something. (It wasn't the bus, that checked out with another drive) The solution was to buy an standalone SATA controller. That fixed my problem. (Or I suppose I could have purchased a newer motherboard, but then that would just make me want to get a new processor, new ram.. etc. You know how that goes) Well, good luck!

[vox-tech] Ubuntu 10.04 LTS upgrade woes
Long story shoty. I have a Kubuntu 9.04 install. Finally told it to upgrade, and it brought itself up to 9.10, and then I initiated an upgrade to 10.04. It started reporting errors, with the only options being Report Bug (which did nothing) and Close (dismiss error). It got through all of the pkgs in the Upgrade step (next step being Cleanup) and complained that some stuff wasn't installed, and it would issue a dpkg-reconfigure -a or somesuch to fix itself. Dimissed that window, then the main window hung (blank). It's late, and it looked in a bad state, so I zapped it and rebooted. Now I'm landing im a shell upon reboot with a complaint about mountall not taking some argument or another. So... anybody got a 10.10 disc I can borrow? I'd like to boot into LiveCD mode, re-copy my home directory over to my NAS, and then wipe reinstall. I'd love to get back up and running before Tuesday. Anyone got one I can grab in the morning? ;) This is the worst upgrade disaster I've witnessed. Stupid Ubuntu. :( -- -bill!

[vox-tech] Idea for 'tee' -- shut up already!
So I'm grepping cut'ing a huge log file (6.4 million lines)
and made the mistake of deciding to pipe it through tee to
watch for a while. I forgot to do this from within a screen
session, so I'm kind of stuck staring at it in a terminal. *sigh* :)
I don't want to watch any more, and wish I could do something like,
I dunno maybe like this...?
$ cat hugefile.log | grep whatever | cut -f 1,2,3 | tee output.txt
{huge dump of data}
^Z
[1]+ Stoppedcat hugefile.log | grep whatever | cut -f 1,2,3 | tee
output.txt
$ kill -SIGUSR1 %1
And then resume:
$ fg
{wonderful silence}
or background:
$ bg
[1]+cat hugefile.log | grep whatever | cut -f 1,2,3 | tee output.txt
$
In other words, a way to tell tee to shut up and stop dumping to stdout
any more (but keep copying from stdin to the file specified).
I wonder, is there any other Linux'y trick I can use in the meantime?
(Maybe fiddling in /proc ? ;) )

[vox-tech] scp bandwidth limit
My DSL is assymetric. Uploads slow down everything else (most notably, my SSH sessions). This is particularly noticable now that I have a WiFi router that does more than just 802.11b. (In other words, it's a lot easier for my laptop to saturate my DSL bandwitdh now ;) ) I find that things work nice if I limit the upload speed using scp -l 240 (30KB/s, since it seems to max out at about 50-60KB/s). However, I'd like to do this only when uploading, not downloading. So setting up an alias (e.g., alias scp scp -l in my ~/.bashrc) isn't the best solution. Is there a config somewhere that I can use to limit 'local - remote' transfers (uploads), while not limiting 'remote - local' transfers (downloads)? I don't see _anything_ related to bandwidth limiting in man ssh_config (which kinda makes sense, since the -l option is specific to scp). Is there some scp config file that I'm not discovering? :) -- -bill! Sent from my computer ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech
[vox-tech] php-cgi hanging on semop()
So I'm noticing some stability issues with a website.
* lighttpd 1.4.x
* php 5.3.x
* mysql 5.1.x
The symptoms to the outside world include lagging connections and,
eventually, Error 500s from the webserver.
Internally, I run mytop (basically, a 'top'-like interface that
parses the results of a show full processlist query). mytop shows
me what connections are active.
Typically, most of our connections are relatively active (only idle a
couple of seconds, at most; If the website's not very busy, the idle
time in some of them can climb in idleness).
However, in the situation I'm seeing, all of the connections from the
webserver are idle, and their idle times continue to increase.
Basically, the current connections between the website and the
database aren't doing anything (not running queries for the website),
and are just sitting there exhausting MySQL's connection pool.
Since this has only started happening recently, and usually after-hours,
my quick-fix has been to do this:
sudo /etc/init.d/lighttpd stop # stop webserver
sudo killall php-cgi # kill all php-cgi processes
sudo killall -2 php-cgi # no, REALLY kill them
sudo /etc/init.d/lighttpd start # restart webserver
And things have typically been fine for at least another day.
Today, it has happend a _FEW_ times during business hours, so I
get to drop everything and investigate. In my job, I am a
literal Jack of All Trades, Master of None. (On a good day,
I spend my time doing web app development, so I suppose that's
my main job ;) )
Google hasn't helped me much, sadly, so I've decided to post here :)
Briefly, here's what I get if I try to attach an strace to
one of the running php-cgi processes. Note: I see the
same thing:
- before stopping lighttpd
- after stopping lighttpd, but before 'killall php-cgi'
- after 'killall php-cgi', but (obviously), before 'killall -2...'
So here's the clue, gang. Like, ZOINKS!
Process 17180 attached - interrupt to quit
semop(229383, {{0, -1, SEM_UNDO}}, 1^C unfinished ...
Process 17180 detached

friend. Sadly(?), the server's been chugging along fine

This isn't really specific to any kind of data.
It just means a stream of octets (8-bit bytes).
Wikipedia sez:
The Internet media type for an arbitrary byte stream is
application/octet-stream. Other media types are defined for byte
streams in well-known formats.
When accepting file uploads from browsers, I've coded up my
form-accepting code to see this as one of the 'useless catch-alls'
that a browser might report. In other words, when someone goes
to upload an MS Word DOC file, I _might_ get one of a vast
variety of MIME types that seem to mean MS Word DOC.[*] But if I get
application/octet-stream, I end up using a fileinfo library to
try and determine what, exactly, the data actually was.
[*] So far, I've seen:
application/msword, application/x-msword-doc, application/x-msword,
{OCTAL 12}- application/msword, x-type/x-doc, application/vnd.ms-word,
application/vnd.msword, application/vnd.ms-office,
application/mswordapplication
Also, the 'catch-alls' I've discovered I need to use, so far include:
application/octet-stream, application/download, application/x-ole-storage,
application/x-download
And finally, iTunes seems to screw up some people's browsers, causing it
to report the MIME type of anything they try to upload as being some
iTunes LP file. Nergh!

Indeed. Furthermore, a more proper way of altering constants for your own app's purpose would be to redefine them in your source, rather than alter the library's header file. e.g.: #include some_library_header.h #if defined(SOMECONST) #undef SOMECONST #end /* Override some_library_header.h's SOMECONST with my own number */ #define SOMECONST 1234 Obviously, this changed constant will only be visible to the file(s) that see the above C preprocessor commands. But do keep in mind, as explained earlier, even if you change some #define's _in the system-wide header file_ (e.g., if I go in and screw around with /usr/include/stdio.h), those changes will only affect: * programs compiled with that header * and compiled AFTER I edited it The stdio library itself, and any applications which were compiled against the stdio.h header prior to my edits, will REMAIN UNCHANGED. I'm throwing these caveats in here because I think we still don't know exactly what you're trying to accomplish. :) Based on the vague requirement of need to change numbers in a header file, what you're trying to do could range from trivial to impossible to downright dangerous. :) -bill! ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

Guys, I'm sorry about asking this on the list; but I seem to have a mental

That's what this list is here for! ;)
I have a lot of directories with a vast number of files, some of which I wishy
to delete based on the month they were created. I've built a file from some
full directory listings that has all the files I wish to delete. (Just go with
me on this and don't suggest alternative methods of performing the task - I'm
simplfying the job so it can be explained more easily.)
Another alternative might be to use find to find all files created
or modified within a certain timespan, and then delete them.
(Or simply list them, which you can capture into a file for review,
and delete the files at your leisure)
You could also use 'find' as a means of getting easier-to-parse output
(additional or fewer fields, and formatted differently) than what you
get from ls -l.
e.g.:
find -mmin +43200 # more modified more than 30 days (30*24*60 minutes) ago
find -not -newermt '2010-04-01 00:00:00' # files modified ('m') longer ago
# (not newer) than the date ('t')
# April 1st
Of course, I've pretty much never had reason to use these, so I might be
off the mark with them, but I figured find is a lot more flexible and
safer than ls -l followed by regexp magic. ;)

So I've got a system that receives images from users We then ship those out to a 3rd party. This 3rd party requires that they be JPEGs (easy to convert to) of a certain size (easy to check) and in RGB colorspace (vs CMYK or Grey). I had a great bit of difficulty, and simply threw my hands up, when trying to encourage a greyscale image (that is, a picture that's only grey pixels) to become an RGB colorspace JPEG. Every automated tool I tried (libjpeg-progs, ImageMagick, possibly others; it's been a while) seemed to ignore my colorspace hint, and said to themselves ah, but it's only grey pixels; let's just save it as Grey colorspace!) Does anyone here have any suggestions on a tool that can handle this for me? (Again, this will be running on a server as part of an automated process, so desktop apps are out; don't bother suggesting The GIMP :) ) I'd be willing to whip something up in C that used libjpeg and ran on our server to handle the 'force-to-RGB-colorspace' task. (The other idea I had was to introduce an off-grey pixel into the source image, to convince the tools we're using now that the image really does deserve RGB colorspace :) ) Thanks in advance, -bill! ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

Any instance of an incorrect constant can of course result in an incorrect parsing of a protocol, but is not detectable at compile-time since using the wrong numeric constant still type-checks.

Yes I know I can download it from Mozilla but I really would like to have it as a package so I don't have to worry about updating it myself. Right now I'm taking a look at Osmo.
