Here are the details: * Sometime I communicate with corporate users and in the beginning I used the same text/plain format as always. * However, unlike modern mail clients, their mail clients display quoted and unquoted text exactly the same (yes, Outlook. I'm looking at you). * The result is that it's very hard for them to read a mix of quoted/unquoted text. Which explains why top-posting is so common among users of that legacy mail client :-( * As a workaround, I started sending them HTML mail and apply a different visual style to the quoted text before mixing my reply text. The style I used was: green text (as in kmail), small font and ITALICS. This way they get a reasonable rendering of the intermixed text. * As Baruch just observed, in the text/plain version, kmail convert the italics to: /text-text-text/ Conclusions: * Re-check non-HTML mail before sending (IIRC, kmail used to have non-HTML/HTML settings per-corespondent or per-folder -- but maybe I'm wrong). * When replying to corporate users, don't mark the quoted text with italics, only with color+size, so the visual rendering of text/plain would be more consistent with text/html.

Spaghetti is not > free software. Not in any sense. 1. You should not be too worried about "the lost art" of kernel compilation from sources. Yes, only a tiny fraction of Linux users today compile their kernel (gcc, whatever)., but comparing fractions is a mistake. The *number* of people doing these compiles today in comparison with, say, 15 years ago is many-fold. It's simply that we now have many more people who are *only users* and should take their needs in account *as well* -- It doesn't mean we have less *developers* or that "very few" can do this the "old way" 2. The system in general *is* more complex today than 15 years ago. But attributing this purely to developers "surrendering" fashion is ignoring the real changes that affected Linux during this time: a lot more architectures, more cpus (numa), dynamic peripherals (scsi, usb, hot-plug pci, etc), hot-plugable cpus and ram (balloning) virtualization, embedded systems. And please note I only mentioned hardware related changes, ignoring functional changes (e.g: desktop integration) So not only you can compile your own stuff today, many of us do this pretty routinely (you cannot evade it completely in embdeded space yet). However, if you want to compile key parts of a modern *desktop* you'll simply have to work harder. BTW: the apt-get/yum mentioned before in this thread would also help you compile on your own because they can both bring you the build dependencies (and document them for you) and also contain the steps required for the build (which you can compare with your manual process if you have problems).

"MeToo", but notice that it's not needed anymore with modern desktops. Since Fedora-13 (I now user 14), both GNOME and KDE mixers are fully pulseaudio aware and show the required controls natively.

As a matter of fact, I went for that approach. Time will > tell if that was really a quick fix. You should note that some of the complexity is the result of greater integration. This is true when we talk about audio which in my case (Feora-14) invovles ALSA, pulseaudio, Phonon (yes I use KDE) and the applications themselves (some KDE, some not) However, you can see the same phenomena in the UI area (X-server, X-server-drivers, kernel-drivers, desktops [including sometimes composition managers, OpenGL, besides our loved window managers) Example for this integration: In another post, you asked about the mixer -- current GNOME and KDE mixers show/control the pulseaudio settings (including separate volume control for separate applications). However Older versions had problems because they "saw" both the ALSA hardware control (which only confuse the user, because their names vary for every audio-card) and the software mixer created by pulseaudio. This means us normal users (not RH University graduates ;-) have two options: * Becoming [semi)-experts in the (e.g: audio) domain. This has a lot of benefits, but not always possible (time limitations) * Trust our stack integrators, both upstream and packagers. At the same time, try to check them and help them by opening bugs, talking with them on mailing lists, IRC etc. BTW: When pulseaudio entered Fedora it uncovered a *lot* of latent bugs in different ALSA drivers. Part of the improvement in pulseaudio over the latest release is due to fixing those kernel bugs. > The truth is that the difference between the versions is that FC12 gives > you 0.9.21-5, while FC14 gives 0.9.21-7.

Again, trying to upgrade bits and pieces (with --nodeps?) will no doubt help you graduate the RH University (unless you drop in the middle) However, it's not the most effective way to solve your direct problem.

[Haifux] Wanted: FOSS IT service provider in the north
Some background,
We talk about a small startup company located in the north ("Gush Segev"),
with Linux based products that are being produced and sold for the
last ~5-6 years.
The environment includes several Linux desktops for the developers,
Linux servers, several Windows(TM) desktops/laptops (accounting,
marketing, etc) and IIRC one standalone Windows server (for ERP).
Until now, all of this was basically self-maintained. However, we now
want to contract an external company to handle all the IT related stuff.
There is no shortage of such service providers and some proposals were
already being made.
HOWEVER!!! We naturally have a very strong preference for integrating
FOSS IT solutions.
Highlights:
* We talk about a startup not a huge corporate. So scaleability is *not*
the name of the game -- KISS.
* We need a *service* provider. Any of us Linux guys could have
installed and configure various tools/solutions -- but the whole
point is to save our time.
Therefore, we look for someone to evaluate alternatives, install,
configure and provide *maintenance* with defined response
times etc.
* Note the locality -- Gush Segev.
* An important part of the job is to provide IT services for the *Windows*
users (again, remember the scale, we talk about *few* such users).
Not surprisingly, the linuxers maintain their personal desktops to
their liking (Debian/Fedora/Ubuntu/Centos you name it).
This means, that as long as you use standard protocols/formats, we'll
just configure *our* desktops ourselves.
* If your expertise is AD/Exchange server, you need not apply.
If we wanted to go this route, we already have enough propsals.
We strongly prefer FOSS IT infrastructure that would serve also the
Windows users.
* If needed, for good integration with the FOSS server environment,
FOSS tools/applications may be installed/maintained on the Windows
clients as well.
Just as an example, if the mail solution will work better with
Thunderbird than Outlook it is perfectly acceptable as long as the
provider gives an alternative client for calendaring etc.
* Some proven field experience (clients). The idea is to save our time
not make us clean up after the mess some rookie left behind.
Please mail me and I'll forward relevant responses,
TIA,

An Oops is caused by illegal operation in kernel space (e.g: null pointer dereference, division by zero etc.) It always had two possible results: 1. If it happened from an interrupt context -- a panic (prints a backtrace on the console and freeze the machine). 2. If it happened from a process context (e.g: in a system call), than it's a "normal" Oops -- Don't PANIC ;-) - The calling process is killed with a segfault (as we cannot continue any valid computation). - A normal context switch happens. - Everything continue normally, with the *hope* that there the bug did not cause big collateral damage (e.g: memory corruption) outside of the failed computation. For many years, there were several kernel macros for triggering such events from the kernel programmer side: - BUG() - causes an immediate panic - BUG_ON(condition) - think of it as a kernel "assert()" - WARN() - just the trace, no other ill effects - WARN_ON() - you guessed it.

This is a naive assumption for several reasons: * One important reason for vendors to avoid alternatives are the "incentives" they get from MS -- the prices and licensing terms are set according to the vendor behavior. Vendor may loose a lot of money on his MS licenses by daring to offer lower cost solution to other customers. - A small example -- the phrase "FOOBAR recommends Vista " on *all* vendor publications worth *BIG* money in licenses. - The other side -- Marketing campaign for competing products would cost the vendor in MS licenses (no, we don't talk about EULA's here, these are vendor licenses with very strict terms under NDA's). * The basic trick for any monopoly is to use its power in one market to reinforce its control on other markets (that's why regulation is necessary evil in these cases). An example close to home is what Bezeq once did as a monopoly -- cross-subsides local/international calls. So, a monopoly like MS can artificially make some of its products cheaper than any competition (even have negative price) *for the vendor* Obviously this isn't sustainable in the long run for all products -- However, the trick played by MS is very simple -- you focus on the most visible wins and so you can break them quickly E.g: Make the Eee-PC cheaper with Windows than Linux (at least for vendors), when/if Asus stops shipping Linux Eee-PC's move to the next target. BTW: if you want to mention Dell. Let me remind you this company started its Linux offerings in ~2000 and backed out because of "no-demand". Did they get any "incentives" to reach this conclusion? If not, someone at MS should be fired ;-) Do you think a ~8 years delay by a major vendor isn't important? > On the contrary, they have been forced to drop prices because they're > competing with free software. Not to mention deals with governments, > driven by the fear to lose a huge number of desktops. True, and I also think they won't be able to stop the market forever. But give them enough time and they may just move their monopoly from the desktop to the data-center -- you would be able to use Linux on your desktop but you would pay just the same to MS via server access licenses... (think how Exchange servers are priced and why .Net is so strategic). > So even though they have so-and-so of the market, in essence they don't > control it anymore. IMO, we are in a transition period now -- MS have enough power to force many vendors and limit our options -- our goal is to make it harder for them. In this sense, things like Zvi's act (with all the PR) help send spanners in their wheels and make the market more friendly for us. -- Oron Peled Voice: +972-4-8228492 o...@actcom.co.il http://www.actcom.co.il/~oron "Debugging is at least twice as hard as writing the program in the first place.

I'd like to mention that this is probably one of the worst software courses in the Technion (unless its curriculum was totally changed). The primary mistakes are: * Trying to cover 3 disjoint subjects in one course fails miserably. * The only people that know C++ after this course are those who knew it before or took OOP later. * Trying teaching them about the importance of modularization and encapsulation when they only experienced "Mavo Letichnut" is simply pathetic -- they technically "understand" it, but they don't "get it".

Let's start with iteration. Just inform us when your mouse

for i in `cut -d: -f1 /etc/passwd`
do
if ! echo "Linux party in 5 minutes" | write "$i" 2>/dev/null
then
echo "You missed a great Linux event" | mail "$i"

If that's hard, let's take something simpler -- try to achieve
what pipes are doing with a GUI -- here is a starter for you:
ps -ef | cut -c53- | awk '{print $1}' | sort | uniq -c | sort -n
(the result is left as an exercise to the reader).
This doesn't mean there aren't tasks that are easier with a GUI.
As a generalization, GUI is simpler for rarely used tasks (because
it guides you), while command-line rules for repetitive tasks.

Re: [Haifux] Party????
Hello Yosi, "long time no see". Welcome aboard.
Wow, just browsed my inbox and got smashed with this
huge (multi)-thread subject -- browsed rapidly all (good) suggestions.
1. Technical problems:
* From complaints, seems like disk-space is causing a lot of collateral
damage. Since disks are very cheap (500Gb for less then 300NIS) it
should be easy to put 3-4 likes these in one "server" host in the lab.
(Maybe as a striped volume group for extra performance).
Having these disks shared among workstations would:
- Avoid students most common complaint.
- May reduce unexplained technical problems (at least some crashes
were reported as a direct disk-space problem).
- Since it looks as if students are having general quota problems (as
usual in big places like Technion), it may seduce them to use the
lab services more often ("Hey, I have so much storage here, that I
save some other projects temporarily. This lab is really cool").
* CR/LF problems are mostly archaic non-issue for the last 10 years.
Any reasonable editor (VIM, kate, gedit, notepad++[windows]) and IDE
displays both without a problem (including syntax highlighting etc.)
I suggest ignoring it instead of giving it a prominent space on the
wiki (OK, as Schachar pointed, there are some arcane cases, but
that's true for everything).
* DOK -- https://fedorahosted.org/liveusb-creator has a windows
executable as well.
2. Change control and maintenance:
* A choice of distribution and update policy is critical. I won't
state my personal preference so we don't divert into distro-wars,
but would like to give concrete examples about the effects:
- The version you used contained OpenOffice.org-2.4x while current
version carries OOo-3.x -- as pointed out this is a major change
both in interoperability with MS-Office as well as other features
(select language and zoom directly from the bottom status bar).
- Distribution specific policy regarding big (and changing) platforms
like Eclipse. What versions are packaged? Which plugins are packaged?
* Update policy -- are your workstations fully updated? or are they in
the same state as first installed? This has a big impact both on
security and "normal" bugs you hit every day.
* There is a constant conflict between having "stable" lab and having
current and up to date software. One possible idea is to have
a "rolling-lab":
- Let's assume we have 15 computers, select 2-3 of them and upgrade
them to the bleeding edge version of your distro.
CLEARLY MARK THEM (labels on the monitors).
- Proactively ask students for feedback: What aspects got improved,
what's got worse.
- The feedback would gradually lead you to migrate more and more
machines to this version.
- Lather, rinse, repeat...
* There are other advantages to such scheme:
- The students have an active role, instead of being passive moaners
and groaners.
- The same idea could be expanded later to having 1-2 "sampler"
workstations with different distributions. You'd gradually see
which are the favorites.
- This way, the students would not only compare "A Linux" with Win*
but rather see several different "Linuces".
- On the same page, do you install more than one desktop?
(e.g: GNOME, KDE, icewm). Having choice is one of the key features
and may help students understand the richer world in free software
("A: I hate this desktop. all shortcuts are wrong. B: Come look
at my desktop. It's so better. C: A -- I can configure the
same on yours, you won't need to change desktops").
* About lab engineers:
- What happened to masters degree students? Don't they work in the
labs anymore, or are they Windows-gurus nowdays?
- If not, maybe undergrads can take over or help with the maintenance
core? Then the community would need to help them, but not
actually do the day to day routine.

It's good to have these wizards to help you out from a tough place. But we should not forget the real questions: - In two years the vendor would be several hardware generations ahead. Would they still support the driver for your (than old) hardware? If not, how would you upgrade your system to the next (or next-next) version? - Many times it further limit your other hardware choices. E.g: You want to move a graphics card from 32bit system to 64bit system. Or from Intel to PPC. Does the vendor provides drivers for all your needs? - And it also limits your software choices. E.g: you need to use Ubuntu (it's not a bad choice, it's just an example of a limitation). To take this to a bigger context, that's exactly like Firefox helps you install Flash plugin automatically. It's good to have this wizard to ease the pain, but it involves the same problems: - Would the vendor (Macromedia, now Adobe) release the versions you need (Only lately we got Flash-9). - Would it limit my hardware choices? (search the archives for zillion questions regarding 64bits). - Would it limit my software choices? Hmmm... and what if I prefer konqi or epiphany? (yes, I know konqi can locate and use Mozilla plugins...) In short, all these Aspirin pain relievers are good, as long as it's clear they don't solve the real problems. If we have a choice (e.g: when planning before we buy hardware), it's better IMO to avoid Aspirin-invoking choices.

Yes, in the beginning I assigned it to lid closing. The drawback is that there are times when I move the laptop around (e.g: during OSDC, at other peoples offices, etc.) and having it suspend each time I shut the lid for a few seconds wasn't convenient (network disconnect, etc.) 2. After using suspend2ram for a while, I found that poweroff was rarely needed (It can be suspended to ram for 3-4 days without a single charge). 3. If I really want to poweroff, there's no need to crash the machine, just run the poweroff command. Since it's a rare occasion now, I don't miss the shortcut key for it. 4. Also the power key is very intuitive for this and is well separated on the keyboard (easy to find, but hard to hit accidentally). 5. I'm now looking for new ideas for the, now unused, lid switch... BTW: Today I just found a new idea for the ac_adapter ACPI event: whenever it get disconnected, the script start repeatedly sounding a "siren" sound -- an improvised anti-theft system (which is also controlled by a presence of a specific 'trigger' file).

Surprisingly, the answer is no. Since you use stdio (fwrite), which by default does full buffering in user space (c.f: setvbuf(3)) this does not surprise me.

The idea is to keep the momentum and show more stuff (each lecture is pretty short, ~1 hour). - The Installation is just before weekend so that power users would have a chance to try this at home. This lecture should include an actual demo on a *tested computer*. - The two Q&A sessions are meant to help people who have installed by themselves to finish the post install phase. - People who still have problems should come to the Linux Day. - The FOSS sessions are the place to talk about things like history, ideology, etc. - All other subjects would be pushed into SiL. * The Linux Day: - Not only for new installs, but also as post-install central for people who installed by themselves (power users). - Therefore, some installation stations should be reserved for this cause. - A projector should be connected to one of these. This way, interesting (or frequent) problems may be presented to all power users and diagnostic techniques can be shown. - More emphasis is required to prevent wasting "guru" time on fixing human errors on the part of the installers.

Re: [Haifux] 'Bad magic number in super-block'
Hi, My first suspect is corrupted partition table. This make the disk driver to "think" that the partition starts in a wrong position (happend to me once many years ago when I had a dual-boot machine and some crappy DOS utility messed the partition table). The way to diagnose this is to search for superblock signatures: 1. Find the correct magic number. in /usr/./linux/ext2_fs.h there is a line: #define EXT2_SUPER_MAGIC0xEF53 2. Write (on a different machine of course) a small program that: - Open the device file representing the whole disk (/dev/hda) - Search occurances of this number. - Print the containing block number (There are many) 3. Ignore the false alarms and choose the numbers that are spread equally (8K or 16K or 32K apart -- read fsck.ext2(8)). 4. Now use (-n just checks, no fixes yet): fsck -n -b /dev/hda And pick a block number which *is not* the first one. 5. Was it corrupted? 6. Repeat with the first block number -- is it corrupted? If 5. and 6. show everything is OK, than use some binary editor to fix your partition table. Luck...

TeX is designed with static allocation (no mallocs) so all memory comes from static pools. The only way to enlarge pools (IIRC) is to rebuild TeX (not trivial at all) with bigger constants. However, something looks fishy, as the last time I got this error was under some old TeX in DOS (when you had real memory constraints). Under Linux (or any Unix for that matter), there is no reason to build TeX with small pools since we use virtual memory.

In kernel space many code section have to acquire locks to protect access to shared data. The kernel programmer can use: - Locks that can break with signals. So he must deal with the case the lock is broken. - Locks that cannot break with signals. The later type is easier for the programmer (no need to handle special cases), but the process is not interruptible during this period. Normally, the programmer should use this type of locking only when there is no alternative and the protected code fragment is bounded in execution time. > But if context is switched every now and then, I would expect the > OS to check for signals. Yes, but in your case there was no context switch because: > spin_lock_irqsave(&state->card->lock, flags); > i810_update_ptr(state); <-- This is where it was caught! The spin_lock*(...) family of locks is doing busy waiting and so no context switch happens. If you'll check the definition of this specific call, you'll see that it disable even the 2.6 kernel preemption. Hope this explanation clears it out. What is still interesting is to know if this case of non-preemptible locking was due to programmer laziness or was inherent to the task this code was doing.

I must say that I was also surprised errno returned by the system in this case was EACCES (Permission denied). I would intuitively expect the kernel to return in this case EPERM (Operation not permitted) as this is the common error for "unsupported operations" -- E.g: making a hard link on filesystem that doesn't support it, etc. Indeed, checking fs/exec.c in the kernel source (open_exec function) reveals that the kernel returns EACCES in both cases which is a pitty (I'm almost sure there isn't an official standard relating to this case, as mounting with "noexec" is pretty Linux specific).
