[Haifux] CPU usage percentage doesn't add up
Hello all, A peer of mine is developing a multi-platform C++ application, and would like to test the CPU usage difference of the application between Windows and Linux. However, running `top` shows him that his single process is using 20% CPU, whereas the total CPU usage is only 0.5%-2%. This is a quad-core machine, so even dividing the 20% by 4 will give 5%, which is still far too high. Windows gives him a satisfactory measurement of this statistic. Can anyone here explain why this happens? -- Man is the only animal that laughs and weeps, for he is the only animal that is struck with the difference between what things are and what they ought to be. - William Hazlitt Ohad Lutzky ___ Haifux mailing list Haifux@haifux.org http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux

Re: [Haifux] Router question
What do you guys think about this issue? I want to say that it's pressing, but: 1. This is the only remaining problematic protocol for me. SSH works perfectly, and git works just as well over HTTP nowadays, if I'm not mistaken. 2. It seems unnecessary, in my opinion, for this protocol to exist - it should just be done over HTTP. However, network neutrality is always important, and Bezeq International's claims of "we don't block any ports" become problematic (albeit technically true). Is there anything that can be done about this?

[Haifux] Router question
Hello everyone, I have a Linksys DSL-2760u router/DSL modem, using a Wow (Bezeq) connection to the Bezeq International ISP. It seems that various outgoing ports are blocked - HTTP, HTTPS, bittorrent and SSH work well enough, but - for example - I can't download Android apps from the Market. Easier to test, I can't download PGP public keys. For example: gpg -v -v --keyserver subkeys.pgp.net --recv F120156012B83718 gpg: requesting key 12B83718 from hkp server subkeys.pgp.net This hangs indefinitely. So does this: telnet subkeys.pgp.net 11371 Trying 195.113.19.83... The same occurs for other keyservers, git-protocol, and various other "unconventional" high-port usage. I've gone over the router settings, disabled its firewall (but not NAT, which I need), added my machine to the DMZ (this actually seems to help, sometimes, for git - and even then, only once), tried port triggering... I can't get a consistent result. I should note that this issue only exists for *outgoing* ports.

Debian has also been known to be the base for many other distributions, such as knoppix and ubuntu.

Re: [Haifux] Technion video
The "X2 velocity" terminology is confusing, let's try and set it straight: What students want to do is watch videos at increased speed, without affecting pitch (usually speeding up playback of audio causes pitch to rise, which causes a "chipmunk voice" effect). There are several libraries for Linux which increase audio speed without affecting pitch, the best-known being libsoundtouch. To my knowledge, libsoundtouch has no been formally incorporated into any media player. However, there is a relatively new project called ScaleTempo (http://scaletempo.sh.net) which provides this capability for several media players, including VLC (into which the patch has formally been accepted). Please test a ScaleTempo-enabled version of whatever media player is currently used to view Technion video (vlc, if I'm not mistaken). 2009/11/18 Shahar Dag > Hello > > One of the complains I gets from students in SSDL is that they can't view > the Technion's video in X2 velocity. > I talked with the people from computer center and they told me that: > the video server is MS windows media server 9 > the video encoding is MS windows media video > the transmission protocol is RTSP over TCP > > is there is a way to view the video on Linux (Ubuntu) in high speed? > > Thanks in advanced > Shahar Dag > System & Software Development Laboratory (SSDL) > Computer Science Department > Technion - Israel Institute of Technology > Haifa, Israel > Tel. 972-4-829-4880 > Fax 972-4-829-4878 > > ___ > Haifux mailing list > Haifux@haifux.org > http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux > > -- Man is the only animal that laughs and weeps, for he is the only animal that is struck with the difference between what things are and what they ought to be. - William Hazlitt Ohad Lutzky ___ Haifux mailing list Haifux@haifux.org http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux
Re: [Haifux] [W2L] Call for lecturer + "Linux guru"
In the case that this is only a 20 minute lecture, I wholeheartedly agree. I do think that git should be mentioned, in a one-liner, as "a more advanced tool that also allows you to work offline". So, while I agree that git is too complicated to learn in 20 minutes (takes 1-2 hours from my experience), it has a different upside when compared to subversion: Administration is far easier. This is true for any DVCVS, and stems from the fact that nobody needs write-access to anything but his own files. Users will want to use whatever VCS is taught in order to collaborate, and this requires some support work from the admins, which should be taken into account. Either that or an alternative free, easy-to-setup, fast and technion-accessible solution should be shown.

Re: [Haifux] [W2L] Call for lecturer + "Linux guru"
Of course it would. But this one puts a lot of candy down that same path as well. These mines hurt, but are not fatal (again, from my experience, all mistakes can be recovered if detected within a reasonable time), and git's features make it, IMO, worth the trouble. For example, while many people find the staging area confusing (you have to "add" a file you've changed again in order to commit it, or just use commit -a to automatically add all changed files), it allows git to do awesome stuff like "git add -p"; this command goes over the differences from the previous version (like git diff), and asks you which hunks to stage. This means you can make a set of changes, realize it can be logically split into two, smaller sets of changes, and proceed to commit it as two sets of changes. Or, for a more common case, it allows you to stage only your actual fix to the commit without the various debugging statements you've added across your code in order to track down a bug, and do a quick "git reset --hard" afterwards.

This is for their instructor to do, and for them to be taught about later on :)I'll only teach them how to check out older versions after I explain branches - that way they can be aware of the dangers of committing on non-branches.

Re: [Haifux] [W2L] Call for lecturer + "Linux guru"
I specifically didn't teach them checkout, for this exact reason... Yes, warnings about these things are in order when you're using git. (Specifically we have "always mind your current branch" and "rebasing is a destructive operation", but also "you can always fix these things if you notice early enough", early enough being a rather loose from my experience). On the specific matter of non-branch commits, git does some work to actively warn you when you do so, but I think this could be improved. I still believe that with warning on those two issues, git is simple enough to use, and that the ability to work offline is well worth it.

Re: [Haifux] [W2L] Call for lecturer + "Linux guru"
I tend to disagree about git being too complex. I currently have three students (in a military setting), which have never used any form of version control before, and have been taught basic usage of git - init, add, commit, log, diff, remote, and pull. I've received no complaints as of yet. As long as you're not doing rebases or working with multiple branches (which are much more complicated to do in SVN, and useless in the situation at any rate), the "data loss" problems mentioned above don't exist. Git gives the added bonus of being able to work offline, which is indispensable for a student on a laptop. -- Man is the only animal that laughs and weeps, for he is the only animal that is struck with the difference between what things are and what they ought to be. - William Hazlitt Ohad Lutzky ___ Haifux mailing list Haifux@haifux.org http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux

Re: [Haifux] Fun with timezones in Linux
Note that using TZ=GMT-3 has several disadvantages for me: timezone is set incorrectly (to -10800), is_dst is not set, and the timezone abbreviation shows up as GMT. I can get a better result with my one-liner zic source. This has the added bonus that applications will read it on a call to tzset, without my having to change their environment variables.

Re: [Haifux] The 10th tip?
The choice of shell isn't the worst part (although, seriously... tcsh? holy crap!). Read the assignment itself. A system to manage and analyze a list of delay tickets for public transportation. Good idea for perl (which is explicitly forbidden IIRC, as are sed and awk)? Certainly. But for tcsh? Afterwards (in Matam and in Data Structures, for example), people don't even consider writing a tiny test suite for their applications, even though it's under 10 lines of tcsh and they're given expected input-output pairs as part of the assignment.

[Haifux] Multi-thread debugging for C++ on Linux
Hello all, I am examining the issue of debugging multi-threaded (specifically using pthreads, and written in C or C++) applications in Linux. The basic tools, as far as I can tell, are somewhat lacking; while the DDD documentation does have a screenshot showing a "suspend" button in Status->Threads, this does not show up in my version of ddd (3.3.11), and I can't really figure out how to do this from within gdb. Is it even possible? As far as I know, this is possible with Java, and I'm guessing that it has to do with additional JRE instrumentation (the debugger tells JRE to suspend the thread, and while the Linux thread is running, the JRE code therein does a sched_yield). So my question are: 1. Am I missing something, and this is in fact possible with GDB? If so, is there a graphical interface (my coworkers are fond of those...) which supports this? 2. Is there a different Linux (on x86) debugger which does support this? 3. What is the situation of this problem on other OSes? 4. What other neat thread-related debugging tools (other than suspending individual threads, that is) are there, and which debuggers support them? I've been trying to google the answers to these questions, but so far I've come up short.

Re: [Haifux] W2L + Installation party?
First, I strongly support Tzafrir's point, which is echoed here by Adir: On Wed, Sep 17, 2008 at 7:06 PM, Adir Abraham <[EMAIL PROTECTED]> wrote: > You can add a special table for configurations. It's been done in the past. > Most of the requests are the same. Let's call that place "Practical FAQ" :-) > > That's the only thing which would be truly useful. However, I still think that an instaparty or a supportparty would not be helpful: Consider the climate: Linux is often touted as easy-to-install and easy-to-use. Someone who heard this would not understand why he needs to carry his cumbersome computer to an event to get this done for him, or take specific time out of his day to come in with his laptop. He is told he can do this at his own leisure - and this is what he prefers. Furthermore, he wouldn't want to install a yet-unknown (especially to his neighbours' kid) operating system if he didn't know he could "handle" it himself. Figuring out the downloading & installing part on his own is very useful to gain this confidence (i.e. "if I'm going to use this, I better be able to install it myself, I don't want those guys to do it for me and when I get home I'll be lost without their assistance"). This occurs no matter how much you assure the people that "we'll install it in such a way that you can use it forever and ever by yourself without our help". This creates a situation in which everyone would want to install Linux in their own time, meaning they'd need any initial support at a different time. For this reason, I send new installers to this mailing list if they have any problems, hoping that they might bring their computer into the next Haifux meeting so someone could help them. An organized event might raise awareness, but installations would happen afterwards, at home. I think Orr said it best - what we need is SiL lectures, and lots of them. We can use the W2L advertisements to promote some SiL lectures, perhaps in higher density (and perhaps about topic which are more attractive to new users) around the W2L date. -- Man is the only animal that laughs and weeps, for he is the only animal that is struck with the difference between what things are and what they ought to be. - William Hazlitt Ohad Lutzky ___ Haifux mailing list Haifux@haifux.org http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux

Two more points: 1. Dial-up (and by this I mean DSL and cablemodem) configurations are in wide use today, and are a prime source of problems (cablemodem especially) for new users. However, an ordinary instaparty is useless for this, as it would have a simple router&DHCP-autoconfig based setup which works out-of-the-box. Moreover, the previous instaparty had no internet access *at all*. At the very least, a wi-fi router should be present so wireless cards can be tested. If any help is to be given in an instaparty regarding DSL and (again, especially) cablemodem connections, such a connection must be available in the instaparty, or the whole thing is pointless. > Show them the fun stuff, the cool music players like amarok and Listen, > After installation?

One additional point - almost all of the linux adoptation I've seen in the Technion works like this: People see it, use it for a course, avoid it for a (geometrically distributed) while, then decide to install it (by themselves. All of the adopters I've seen are perfectly capable of performing a google search for the distribution they've seen, burning an ISO, and hitting "next" a couple of times). They seek a guru (or ask on the forums) for some help, are given a pointer in the general direction, and are happy. Sometimes they come seeking more help for tougher issues (laptop doesn't enter suspend-to-RAM properly, cablemodem issues, or they decided to go to a bleeding-edge version, broke a few things, and are interested in knowing how to fix them without going back to a stable version). I move that instaparties, at least in the Technion context, are obsolete. -- Man is the only animal that laughs and weeps, for he is the only animal that is struck with the difference between what things are and what they ought to be. - William Hazlitt Ohad Lutzky ___ Haifux mailing list Haifux@haifux.org http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux

For this exact reason, I recommend against any of those solutions (including the original one).

[Haifux] Active Directory integration with Likewise Open
Likewise Open is meant to be integrated into Ubuntu Hardy (8.04). It's available for gutsy, but poorly documented. Nevertheless, it seems to work very well, with far less painful configuration. The only caveat I can find is that the "group\username" string has to be entered as the username, and I don't think this can change. Any opinions?

Re: [Haifux] Simulated permissions on VFAT
Looking for a simpler solution (although UMSDOS, upon re-reading, seems to do exactly what I wanted, but is discontinued), here's an alternative problem to solve: What I *REALLY* want to do is use my DoK to synchronize two computers, when one of them has very poor upstream (otherwise I'd use the excellent unison over the net). I already currently do this using unison, but I lose permissions, which is a problem. One solution would be to save my files onto the DoK in archived form, something along the lines of this: Write: tar jcvf sync.tar.bz2 files_to_sync/ rsync sync.tar.bz2 /media/DoK/sync.tar.bz2 Read: rsync /media/DoK/sync.tar.bz2 sync.tar.bz2 tar jxvf sync.tar.bz2 However, this would be very slow, even without compression.

[Haifux] Simulated permissions on VFAT
Hi everybody, I'm trying to use my DoK for various things which are sensitive to the executable (chmod +/-x) bit. As I want to be able to use this DoK on Windows systems as well, it's formatted to VFAT (NTFS is also an option, thanks to ntfs-3g). Is there any way to get any form of "simulated" permission bits for the file system, which Linux will take heed of? (For example, an option to a VFAT filesystem module which will read/write such permission data to dotfiles in each directory, and subsequently hide those files from me). Mac discussions talk about a "Sparse filesystem" - I imagine that what they mean is a filesystem-in-a-file, which expands and shrinks to accomodate its contents. This would work well too. ___ Haifux mailing list Haifux@haifux.org http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux
[Haifux] Git Lecture discussion
I hope my lecture was bearable :) Regarding keyword substituion: It turns out that Linus thinks it's a horrible idea: http://kerneltrap.org/mailarchive/git/2006/10/9/223932 (This has the unfortunate consequence of making several of the attendees ugly. Sorry everybody ;) ). It turns out I did something very similar on a whim (not having known keyword substitution beforehand) --- I've created a "make a tarball of this revision" script, which tags it appropriately (in a place appropriate to the application) according to the tag I've selected. Regarding rebasing: Indeed, it is only meant to be used when developing a private branch, and later submitting using git format-patch. (These patches are later applied using git am, and merging/rebasing works properly, leaving no duplicate commits). When working on a public topic branch, rebasing will cause problems for anyone pulling from the repository, so it's best to resort to ordinary merging. As patches usually don't need to be formatted for this usage, this isn't a big price to pay. There were several other issues explored which I couldn't answer properly... can anyone please remind me?

[Haifux] [HAIFUX Lecture] Git isn't a VCS
Next Monday, 4th of February, at 18:30 the Haifa Linux Club, will gather to Ohad Lutzky's (my!) lecture about Git isn't a VCS Git isn't a version control system. No fancy acronym, that's just what Linus says. Still, he wrote it and uses it to keep track of versions of the kernel. This presentation will be one big usage example of git. Knowledge in other VCSs (cvs, subversion, others) is recommended, but optional. Also recommended but optional is viewing Linus's talk on motivation for writing (and using) git: http://www.youtube.com/watch?v=4XpnKHJAok8 == We meet in Taub building, room 6 (note the change of place!).

Hi guys, Git is the version control system used for the kernel. It was originally written by Linus, who wanted a fast, distributed VCS. Anyone interested in hearing about *using* it?

[Haifux] Lecture Monday 24/12: Lecture for CS students
Hello all, This lecture is being given to CS students by the Haifux club. In several CS courses - mainly Matam, Data Structures and Operating Systems, students face the often-unfamiliar Linux environment, and use it to hand in course exercises. Experienced users have often seen them have difficulty with these topics, which the lecture will cover: * Getting around in a Linux environment (through graphical UI and commandline) * Compiling multi-source-file programs properly - first into object (.o) files, then linking * Creating and using Makefiles Furthermore, two very good reasons for students to enjoy (or suffer less, anyway) programming in Linux will be presented: * The Data Display Debugger (DDD), a graphical debugger to make pointer-based data structures almost too easy... * Valgrind, for when you do dumb stuff with memory Additional tips and tricks will be given, which should be very useful for Matam students for the first two exercises (especially the second). The only recommended prior knowledge is basic C programming (for example, Intro to CS). The lecture will demonstrate on a Linux environment, but the topics apply also to using T2 directly. Lecture slides for the first part are available here: http://www.haifux.org/lectures/152-sil/ The lecture will be held at 18:30, Taub 6. (Note the room change - Taub 6!) NOTE: This is a re-run of the two lectures given last semester. However, experienced users will be available to answer questions you may have. -- Man is the only animal that laughs and weeps, for he is the only animal that is struck with the difference between what things are and what they ought to be. - William Hazlitt Ohad Lutzky ___ Haifux mailing list Haifux@haifux.org http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux

Re: [Haifux] My "Stop Using (and Teaching) C-Shell and Tcsh" Page
A few more notes... I'll make it short (it's 1:35am here :-) without looking at the references > (sorry, I'll look at them sometime later, but I doubt they will change > my reply). 1. C-Shell is taught as a "tool" for manipulating programs > (in MaTaM's view, especially for testing) - this answers also the Q > of "why scripting at all?" 2. Students are not expected to become > Csh experts (I may agree that some technical details that are taught > are not necessary) but they are expect to understand its usefulness. > In that respect - any scripting language will do, even Perl. Actually, a great deal of the problem I have is that users aren't really shown the benefits of scripting - they are given that as a constraint. The exercises the students are given are, very often, solvable with one bash script using sed, and in extreme cases - a simple perl one-liner. There is an inherent problem designing a "big" exercise around shell scripting, which is inherently at its best for small, interactive assignments. The students don't learn to see shell scripting as a useful day-to-day tool, but as a convoluted programming paradigm. 3. AFAIK all Technion servers are csh or tcsh (I don't know whether > they provide bash) so it is the environment we have. Ever since I've been a Technion student, bash was installed on T2, csl1, and all of the farm boxes; I've never had access to TX, but I'd be extremely surprised if bash weren't installed there. 4. Coming to think of it, the resemblance with C is an advantage > (despite the "defects" and defects of csh). Seeing as C and shell-scripting are used for inherently different purposes, I do not see why this is an advantage; furthermore, I think that in the exercises which are being taught, far too much stress is being put on loops and "if" statemenets; Too little on effective usage of "&&" and "||" operators. Also, extremely useful unix commands such as sed and find are not taught, and I have actually seen an exercise given in the course where the students implement a crippled version of "find". More relevant uses for shell scripts are never brought as an example - students are not shown, for example, how to use them in conjunction with "make" in order to create a test suite for their programs. If you want to teach scripting - use a scripting language (preferably something more organized than perl, like Python). If you want to teach SHELL scripting, the exercises must be relevant to that style of programming. And two further notes on CSH itself: * It is sometimes non-deterministic, as testified by Matam students; * One-liners are not possible - blocks have to start on separate lines. This makes tcsh very uncomfortable to use in interactive mode. * Its syntax is, in certain cases, much more complicated than bash's: Files are not auto-created when using the append (>>) operator, and outputting to both an stderr and stdout file is a mess. In bash it's just "command > outfile 2> errfile", or for a combined version, "command > combinedfile 2>&1". -- Man is the only animal that laughs and weeps, for he is the only animal that is struck with the difference between what things are and what they ought to be. - William Hazlitt Ohad Lutzky ___ Haifux mailing list Haifux@haifux.org http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux
[Haifux] Lecture proposal(s)
Okay, now that the mailing list is back up, here are some proposals for lectures, let me know what you think. I can give a lecture about PyGTK - creating a user interface using Python and GTK. This lecture should be self-contained; I'll teach all of the python necessary, the audience will only need some background in programming (preferably in an OOP language). I intend to start simple, and finish off with a threaded example; the lecture should be appealing to relatively new but hackerish users. Haggai wants to give a lecture about the git not-a-source-control-management-system, and Ariel wants to give a lecture about monads, but I'll let them talk about that :) -- Man is the only animal that laughs and weeps, for he is the only animal that is struck with the difference between what things are and what they ought to be. - William Hazlitt Ohad Lutzky ___ Haifux mailing list Haifux@haifux.org http://hamakor.org.il/cgi-bin/mailman/listinfo/haifux

Re: [Haifux] Windows in Haifux
Just a few more points to throw in here - In the short time I've been in Haifux, it's been mostly a 'vote-with-your-feet' club. People show up to lectures which interest them, and speak in favor of them on the mailing list. The reason, I believe, we mostly have our "tight-knit" "linux-related" "lectures" (taking all three terms with a grain of salt), is that the topics we choose grow mostly out of the heavily community-oriented Linux/F/OSS... er... community. That is, where Microsoft might [send someone to] give a lecture about .NET, the body to give a lecture about upcoming versions of Perl, for example, would be the perl mongrels themselves. Therefore, the other-OS-tolerance is there, just on different topics. So while a lecture about "here's how wireless networking drivers work in Windows" wouldn't be so interesting, I believe, to Haifux-goers, a lecture about "here's how to get Windows wireless networking drivers to work in Linux using ndiswrapper" - which would certainly include parts of the former - would be very interesting to many of us. Other lectures which might be of interest, of relation to this topic are (off the top of my head) - * An introduction to WiPeer, when (or perhaps more interestingly - while) it is being ported to Linux * Open formats - Opendocument and its implementation in various word processors, perhaps including MS's * Writing cross-platform software (I can already see the subtitle... "or: why Firefox is so damned slow on Linux") * Something "heavier" - design principles comparison between the NT kernel and Unix-style kernels (please don't stone me :)) -- Protect your digital freedom and privacy, eliminate DRM, learn more at http://www.defectivebydesign.org/what_is_drm Ohad Lutzky - Haifa Linux Club Mailing List (http://www.haifux.org) To unsub send an empty message to [EMAIL PROTECTED]

You are correct in the sense that they are expected to do some learning, and I think it's evident from my lecture slides. Furthermore, this lecture is meant as an addition to the Matam course, which already aims to teach the students programming in a Unix environment. don't worry - i'm not going to jump during the lecture and shout "don't listen to him!". just during the Q&A session. if you were teaching people that never saw MS software - i might have had a different opinion. but once they saw it - anything else will be considered "not as good" - even if it is better but different. I find that the "not as good" resistance breaks down once valgrind is shown :) lets not argue here - i think that the MS environment in inferior to the tools i like - but i can see the advantages it does have for people with slow fingers, short memories and moderate laziness ;) The issue is that the Matam homework is checked on T2, a solaris computer, with very strict gcc flags. While many have successfully written and tested their code in Microsoft tools and had it running perfectly on T2, these are usually only the ones who are excellent programmers to begin with. For most people, "finishing" the exercise only to find that they have a lot of debugging to do on T2 is a problem - as they will not have had experience debugging and coding in a Unix environment. Furthermore, the TCSH exercise will force them to use a Unix environment. My point is that the lecture's focus isn't one of "use Linux for your programming, it's better than anything else!" - rather, it's "you're forced to do Unix programming, but it's not as bad as you might think". -- Protect your digital freedom and privacy, eliminate DRM, learn more at http://www.defectivebydesign.org/what_is_drm Ohad Lutzky - Haifa Linux Club Mailing List (http://www.haifux.org) To unsub send an empty message to [EMAIL PROTECTED]

Hello all, I've just had the dubious pleasure of updating the Haifux Website. Mountains of perl scripts and makefiles, a very inconvenient system. My suggestion: Wordpress. It's a 'weblog' application written in PHP, but from my experience with it - it would be perfect for our needs. It supports uploading files, tagging (for example, by lecturer), and is much easier to update. While this is Free software which can be installed on Vipe, it might be beneficial - if this is, in your eyes, acceptable - to use Wordpress.com for hosting - it's free, with no ads, and one only needs to pay for upgraded storage, as they only give 50MB for free.

Since monday is taken (Alon's DV lecture), and I was hoping to do the lecture before Passover, I was wondering on what day some of you could come to help answer questions. -- Protect your digital freedom and privacy, eliminate DRM, learn more at http://www.defectivebydesign.org/what_is_drm Ohad Lutzky - Haifa Linux Club Mailing List (http://www.haifux.org) To unsub send an empty message to [EMAIL PROTECTED]

Re: [Haifux] An introductory of sorts
Define "equal and fair". My intention is to show a few screenshots, say that many prefer it, that many of those do prefer it because it's similar to certain other operating systems, that applications which work here almost always work identically there, that there are distributions (I plan on demonstrating Ubuntu, so I'll mention Kubuntu) which have it installed by default, and then get on with demonstrating Gnome.

[Haifux] An introductory of sorts
It's that time again... Spring semester coming up soon, and I was wondering what we can do to pester non-linux-users around us :) I was thinking something small, CS faculty, a few printed A4s. One lecture, one hour, a bit CS-second-semester-oriented, but not technical. That is, we should say something motivational about "you'll have to use this anyway", and that's it.

Re: [Haifux] Re: version control & wiki
I (n-verb) that. TRAC is amazing, and very comfortable to use. its functionality can also be augmented through many available plugins.

Re: [Haifux] Please read the following with a smile
It is a sad state of affairs in which I can't even give the lectures I've been planning to... not this semester, anyway. I'm hoping to rerun C without a spoon for the beginning of next semester, as well as my Linux for CS student lectures. Spring is a bigger Matam semester, so it should be quite successful. However, I don't think I have anything particularily interesting to show for intermediate users upwards...

Re: [Haifux] My very own lecture.
On 12/23/06, Orna Agmon Ben-Yehuda <[EMAIL PROTECTED]> wrote: I suggest that instead of scheduling a room and a lecture, we set an informal gathering - a meeting which is all a break, without a lecture. A topic for such a meeting can be brainstorming over topics we would like to see discussed on Haifux or projects that Haifux members can do. How about that? Without regard to any specific lecture, I think this is a fantastic idea. Especially when there are no lectures in the queue - there is no reason not to meet at all. I'm sure a Haifux meeting could be quite fun and informative "even" without a prepared lecture. -- Protect your digital freedom and privacy, eliminate DRM, learn more at http://www.defectivebydesign.org/what_is_drm Ohad Lutzky - Haifa Linux Club Mailing List (http://www.haifux.org) To unsub send an empty message to [EMAIL PROTECTED]
