[Haifux] the state of linux gaming
a lecture or two ago, when Guy Keren was saying that linux would never ever be a gaming platform i tried to point out he was wrong, and it's actually doing OK, and everyone looked at me like i'm crazy. anyhow, if anyone wants to try, Borderlands 2 Game Of The Year edition (that means all the expansions) is on sale on steam. steam is the game store thingy every one uses these days. It's available for linux. http://store.steampowered.com/sub/32848/ there's a big list of games avaliable for linux, and it includes about 1/3 of the new ones, and 100 games total (remember, these are mostly recent big-name games). Namely, Portal, which by many is considered the best game ever, so if you want to support the cause, consider buying portal for linux. anyhow, here's the linux game list http://store.steampowered.com/browse/linux/ also, for those who prefer indie games over big-titles, the humble indie bundles are 9 out of 10 times windows-linux-mac compatible. ___ Haifux mailing list Haifux@haifux.org http://haifux.org/mailman/listinfo/haifux
Re: [Haifux] The Bash vulnerability (shellshock)
you need to find a vulnerable site. CGI doesn't have to pass through bash.
you need a site that opens a subshell for something. they aren't uncommon,
but it's not every linux-CGI site.

Re: [Haifux] Orientation Day at the Technion
no need for SIL. of the people i've met, there was one who has been a linux user for the last 10 years, and one who is part of ubuntu IL, and took the initiative and set up a stand at ICon (and is already on this mailing list ;). they are already staying in linux. on the other hand w have people who are not all that linux-heavy, but are computer geek none-the-less, and would probably feel much safer about the hole thing if they show up once and see that we don't bite. no idea what orr is planning for secure file systems, but if it doesn't require people to deal with the mathematical definition of a cypher or a hash function, or know in advance how a file system works on the inside, it may be perfect. alternatively, a rerun of a lecture that was fun, or lightning-talks, a non-lecture activity to get to know the new people, would be would be nice.

Out of about 200 flyers, 10 were left when guided groups stopped touring (around 14:30). We had some luck with CS, EE and IE groups. We focused on those groups, as there was a burst (a rush hour). Furthermore, groups came by faculties, more or less, as the talk in each faculty ended at a different time. We were located on the promenade at first, then moved nearer to the ASAT building. On hind sight, we should have positioned ourselves first at Taub, then moved to ASAT building. The people who are most likely to show up, in my opinion, are those who already knew what Linux is, and now found out about the club. However, we must remember that those people have had not even one CS semester, so maybe it will be better if the upcoming talk was a talk which does not require any background, and is yet a technical talk (newcomers do not need persuasion - they need an intro to the club).

Re: [Haifux] preventing caps lock at the kernel level
sorry for the slow update. my controller is indeed the i8042. however, the current version of ubuntu has kernel 2.6.31 which does not have the i8042_filter() function yet. the advantige of keeping the kernel with ubutu's configuration is that all the tuning they've done to get esoteric hardware to work out of the box remains. as my laptop is mostly esoteric hardware (HP tx2000), it made more sense then to try a new kernel and both try to debug my changes and the kernel config options at the same time. after some useful information from this articlehttp://gunnarwrobel.de/wiki/Linux-and-the-keyboard.html and the specification links it led to, i concluded that the scancode in my system for caps lock is 0x3a, and placed the following code near the beginning of the function i8042_interrupt(). if(data == 0x3a) goto out; while this fixed the caps-lock, it made the mouse and tablet go crazy. upon further thought, i changed it to this: if(data == 0x3a port_no == I8042_KBD_PORT_NO) goto out; a vast improvement. still, some special keys acted wrong, so i ended up moving it to near the end of the code. and thanks to rami for pointing me in the right direction. On Sat, Mar 20, 2010 at 13:49, Rami Rosen rosenr...@gmail.com wrote: Hi, Boaz, I suggest that you'll look at the interrupt handler of the keyboard. Usually, the i8042 chip family is the keyboard controller in desktops and laptops. First make sure that i8042 is indeed the driver you are using; run cat /proc/interrupts and see whether interrupt number 1 (the keyboard interrupt) is handled by i8042. Then goto drivers/input/serio/i8042.c; i8042_interrupt() is the handler for keyboard interrupts. You can try add a filter there for Caps Lock. Even better is try to add code in i8042_filter() method, which is called from i8042_interrupt(); this way you can be sure about locking. I think that you should **not** try to write a simple module which hookskeyboard interrupts. While this solution is usually better (you don't change kernel code), I think it won't work in this case. Namely, if you try something like this, in a kernel module: free_irq (1, NULL); res = request_irq (1, mykbdhandler, IRQF_SHARED, mykbd, dev_id); I think you will get an error, since interrupt 1 (the PC keyboard interrupt) is edge-triggered (see cat /proc/interrupts; for interrupt 1 it says:IO-APIC-edge ). In case of level-triggered interrupts this might have been OK.

have you tried virtualbox? it's GPL, and i've had some good experience with it.

They are running Windows 2000 and Redhat 7.3. I only tested the Windows part (Linux should be much easier). Fedora 12 is the host, of course. I've looked at QEMU/KVM vs. VMWare. I want to share my experiences and insights with you, because I don't like the bottom line, which is the VMWare is better for almost all home purposes (I'm not talking about cloud servers and such). Which makes me wonder: Is VMWare a honey trap, or is it currently the preferred choice? In case you wondered, both tools can run simultaneously on the same computer, seemingly without disturbing each other. It looks like I'm going to take advantage of this. I ran VMPlayer (free as in beer version) with VMTools in the Windows guest machine. I take it that their licenses don't limit me in time nor the number of guests I can run simultaneously. Please do correct me if I'm wrong on this. The concept is to copy these machines' disks as image files, and then seamlessly go on working as if nothing happened. The most important issue for me is that after the transition I can go on doing everything I did before (including using electronic development hardware through USB). I should mention, that both tool's documented and encouraged flow is to install a new operating system from scratch on a blank (virtualized) disk, and not run a previously installed one. Indeed, a preinstalled XP image tends to give me the blue screen. The Windows 2000 image runs beautifully. QEMU/KVM Pros * Free (as in freedom) * Allows incremental images (good for running possibly malicious software) * Can be run from the command line, and is generally script friendly. * Appears to be more secure (SELinux is all over) * Display on VNC allows remote access to guest QEMU/KVM Cons: * Doesn't currently have an EHCI driver (and hence guest sees only USB 1.1, not 2.0) * Didn't manage to attach a USB device I need for electronics development (Xilinx programming cable). * Has Windows paravirtualization drivers for network card only. Display is slow. * Using the mouse is annoying (poor tracking, clicks are sometimes missed). VMPlayer Pros: * VMTools offers a nice set of paravirtual drivers * Very good emulation of graphics card (through paravirtual driver). Feels like a real computer, it's possible to play movies. The guest's desktop size is dynamically adjusted to the virtual machine's window size, which is pretty convenient. * Very good handling of USB hotplugging. Needless to say, it handled my special piece of hardware seemlessly. * Easy to feel with mouse. VMPlayer Cons: * Feels like it was designed for Windows host. If you can't do it through GUI, you can't do it at all (?) * Everything about their website says we'll give you this for free (if you manage to find it), but you really want our million dollar version So this is my grim bottom line: I don't like the music I get from VMWare, but VMPlayer does the job, and QEMU is almost there. But almost is not enough when you want something to work. Remember that I'm the one who wants his computer working, first and foremost? Your information, comments and insights are mostly welcome.

Re: [Haifux] advanced of programming in Linux
a good example is copying ownership of a set of files from one computer to
another.
lets say someone messed up the permissions for all of /opt recursively, but
we have the same /opt on another computer. we can obtain an ls-like
description of all the files with
find /opt | xargs -n1 ls -ld
copy the output to another computer and run
cat /tmp/permissions.out | awk '{print $3 : $4, $8}' | xargs -n2 chown
i once saved a solaris machine that someone ran chown -R root:root / on
with that.

as for scripts Windows
Windows have many scripting capabilities. It is true that we mostly ignore
them (maybe becase they are complicated)

2. visual basic scrips (if you know how, you can use any dll in the system

I think the strong point is The Unix Way, which is a mix and match of
tools, each good at doing a specific thing, by using shell , pipe and make.
Linux did not invent The Unix Way, but like other FOSS, it provides more
options for the mix and match. Indeed many Unix systems are closed source,
and the Unix Way works there, too (better than it would work on Windows, I
expect).
A point specific to Linux and Intel/AMD is valgrind, with which I nowadays
solve memory issues within seconds of programmer time. Solving similar
problems before I had Linux took me weeks sometimes (for a code I was not
familiar with, of tens of thousands of lines), and sometimes I just gave up.

Re: [Haifux] [W2L] Call for lecturer + Linux guru
i don't think 20 minutes is enough for subversion if students are to use svn+ssh:// from t2. an hour is minimum. it should get it's own seperate lecture, IMHO. also, it shoudl be pitched seperately, as it has apeal also for students working on obscure OS's that arent POSIX-like. just another hook for FOSS. git, imho, for your averige MATAM student, would take much longer than that to learn, to the point where it's useful. once you understand SVN and have some experance, it's much simpler to learn git later down the line.

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.

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. There's a succinct list of reasons I like git here: http://whygitisbetterthanx.com/ I'm getting the sense that this conversation has gone off the main track a little. This is, I'll admit, also my fault. The question here is not which VCS is better (for which my answer, if you look at it, is depends), but which VCS should we teach in the dev lecture of the W2L series. Here's the thing. When you first start to use a new system, what you see is mostly the mines. If this is the first system of its kind, you are likely to run into mines that are not really mines, but your misunderstanding of what the system is supposed to do, but still, the mines (real and conceptual) are mostly what you see. You do not, typically, see the candies, for the very simple reason that you do not understand the system well enough to appreciate or make use of them. As you use of the system matures, you learn to change your thinking to not regard some things as mines, and avoid the real ones. As that happens, the mines become less and less important, and the candies become more and more interesting. The main pre-requisite for that happening is that YOU HAVE NOT GIVEN UP ON THE TOOL! This thread started around a very specific question - should Haifux teach git, or some other version control system, as part of the development tools lecture. Any answer should take into account that amount of time given for this part of the lecture (between 10 and 20 minutes), and the amount of tutoring the students will have down the road (none unless they seek it). Under those conditions, in my opinion, git is the wrong tool because: - Anyone who has any experience with VCS will, likely, have used server based ones. Git, for them, contains all of the misconception mines that go with a distributed revision control - Git has some actual bone-fide mines, lain on the path traversed even by relatively basic VCS operations. - None of the candies matter, as you only have 20 minutes (best case) to show them the tool and set them on their way, and the candies require the user to get version control in order to be appreciated. With the amount of time you have, you will be lucky to get 20% to appreciate the fact they can restore any version they checked in in the past. Showing them git because it can split a single change into multiple commits will fly so far over their heads, I'm afraid none of them will even run a single git

Re: [Haifux] Idea: Welcome to Open Source instead of Welcome to Linux this year
IMHO it's a branding issue. Linux is a brand name. When you say Welcome to Linux it has associations. When you say welcome to FOSS, people give you a blank stare, and then you have to explain, all the while making sure your arguments don't enter tin-foil-hat land. It's not as if Welcome to Linux involves compiling your kernel, loading modules, or creating device nodes. It has very little to do with Linux itself and could be done on BSD or HURD for all intents and purposes. You show them gnome/KDE, firefox, OOo, gimp, etc. So in short, while it's a great idea, I think there's an advantage to the branding that gets people to come.

Re: [Haifux] An introductory of sorts
while the industry is nice and all, if someone uses linux for homework, and then goes to the industry, he is still likely to choose the familiar windows desktop that he is used to. that is why i feel desktop linux is so important. and if beryl has the effect of creating desktop linux users, even for the most shallow and meaningless reason, i say we go for it. after all, anyone who uses linux on his desktop, is much more likely to use it at work. On 2/7/07, Eli Billauer [EMAIL PROTECTED] wrote: It looks like you wanted this to go to the list...? Anyhow, we happen to agree on the purpose, not on how to achieve it. I believe that the main obstacle is to make people friendly with a new creature. And you get friendly with what you happen to have around. Yes, some people have switched to Linux without this, but how many of these are they? I believe that if a CS student did two courses with Linux, but ended up thinking that it's pretty handy, this could affect future decision about what to choose once he or she reaches the industry. Or at least be fully aware of the fact that something free can be useful. Which is much more than what is commonly thought. Eli boazg wrote: this is a very nice idea, and it would make CS student's lives easier, but it misses the goal of getting CS students to stick with linux after MATAM is done. while this would seem rather shallow, we have seen several people stick with ubuntu for beryl alone and no other reason. even if they end up not using it. sad but true. as for the custom distro, great idea, but if it used the user's NTFS drive it would make life simpler, and this distro would take time to make. time is the key. the simple show-off lecture takes little time to prepare. and last but not least, CSux is a problematic name. i would go with white night linux. or TauBuntu if it was ubuntu based.

Packages are nice, but downloading them requires that you get your internet connection right under Linux. Desktops are cool, but they are not reason enough to switch from a well-known environment. I would suggest to create a CS Student edition (CSux is maybe a problematic name) of a some LiveCD/LiveDVD distro. The idea is to tweak an existing distro to include the environment a student needs for CS tasks, with a guarantee not to touch the hard disk. Files would be saved on disk-on-key. Maybe a 256 MB RAM disk could be used to keep the most commonly used executables and libraries. Something you can give away and say: Use it, it's good and it's safe. The relevant icons should be on the desktop (editor and maybe a page which gives some tips), so that the average student would get along well right away. And since this distro needs very basic hardware features, there's not even a rush to update it too often. The point is, that if a student uses a tool for a semester or two, there's no better way to make him or her aware of the existence of something else than Windows, which is actually good.

[Haifux] Disappointing Linux Day
I would like, on behalf of myself and Maya, to express my disappointment in the Linux Day we had yesterday. Adir, while you did take leadership of the project, I feel dissatisfied with the way things worked out. The most basic necessities for an installfest were unavailable. Power bricks were in short supply, and there was no network available. There was not even a proper screen on which to project a demonstration. Without these, I feel, there's no point of having the linux day at all, A second, very important part, was the choice of distribution. The majority's vote was for Ubuntu - a distribution that I myself, as well as other Haifux participants, have been using and thoroughly testing (for user-friendliness, stability, support, etc.) for a very long time - two years, in my case. However, the distribution which was chosen was OpenSuSE (which was recommended only by Adir). Only one installation was accomplished, despite our best efforts - and this with a DVD which seems to have been burnt properly (because it installed properly on Adir's laptop). From chats I had with some of the arrivers, this is a known issue with SuSE. Furthermore, for people without DVD drives (and such people did arrive, and we must recall that most people are inclined to install Linux rather on their older machines), SuSE has an inordinate 5-6 CDs, which weren't even made available. Almost all installations which were performed yesterday ended up being Ubuntu, from makeshift burnt CDs (all installs but one were flawless, BTW, and that one had a severely damaged hard drive) However, the most important part which was missing was advertising. Everyone but the organizers shared this complaint: They found out about it too late (if they had found out earlier, they would have brought their machines). This is particularily peculiar, seeing as the Yes sponsorship was intended to fix exactly this recurring, well-known problem. I hope to see better solutions for these problems for the next Linux Day. -- To necessity... and beyond!

Re: [Haifux] Disappointing Linux Day
just for the record i would like to oppose this drawing of knives whitch is taking place.
Re: [Haifux] Disappointing Linux Day
i for one stand behind adir. he worked very hard with a very limited staff, and while it was far from a perfect linux day, with all things considered it could have scarcely been a better one. claiming he should have had more of something is merely whining. were do you get more stuff? It doesn't just pop out of thin air! furthermore, while i disagree with the choice of distro, it isn't a bad distro or an awful choice, i merely think ubuntu's advantages are slightly better, and as this is a subjective matter this doesn't make his decision wrong. last of all, the failing DVD's were quite a stroke of Murphy's law, that was all it was, and holding adir to blame for it is absurd. all in all, few could have done better, scarcely much, better and complaining about it isn't helping making the next one good either!On 6/26/06, boazg [EMAIL PROTECTED] wrote:for god's sake man, adir worked very hard and tried to make the best of what he had, and your one point of disconcent, the distro, is not enouth to go calling him a failure in public in that sort of way. furthermore, as he hadf the most at stake, we both watched as murphy's law beared down uppon him at a critical moment and to add insult to injury here is quite pointless.On 6/25/06, Ohad Lutzky [EMAIL PROTECTED] wrote: On 6/25/06, Adir Abraham [EMAIL PROTECTED] wrote: I'm sorry to tell you that I did my own tests, and no distribution's decision is finite.

And time after time,ever since it was released, Ubuntu has proven to be a better choicefor new-intermediate users than the others, and by its own right avery powerful and comfortable OS. I've seen many people switch from other distros to it, and be very happy. Admittedly, I have nilexperience with SuSE, but saying that my decision for Ubuntu is blind,well, that's a bit much. I'm glad that you achieved a 2 years experience(!) with Ubuntu. Happy for you. If you ever want to do an Ubuntu Linux Party, you go and do it. You have no right to complain here. You didn't like the decision from the beginning. Every time you could just leave, and I wouldn't try to hold you.Ah, but here you miss the point. I don't work for Ubuntu and Icouldn't care less if people run it or something else. My interest wasto better the experience of the installfest for the installees (to promote F/OSS, blah blah blah - but specifically, to make the linuxday a good linux day). And I believed then as I still do now thatUbuntu would have been a better choice of distro. However, seeing asyou wouldn't accept this option (at least not until installations failed left and right, and/or the first person without the DVD drivecame along), I was faced with two options: Either refuse to help, orhelp. Believing that I can indeed help, I stayed on board. But thatdoesn't revoke my right to bitch about the distro. --To necessity... and beyond!Ohad Lutzky
Re: [Haifux] Linux Day: Choosing the right distribution
me and the farm crowd strongly stand behind ubuntu. the 6.06 release takes simple to a whole new level. it has hebrew, a new, much nicer, clearlooks derivative theme, and apt is quite the leader in package management. they;ve also put a frontend on apt simpler than synaptic for people who want to save time. backed by automatix, a script making installation of common non-ubuntu things (like swiftfox, or w32codecs), very simple, and by HebUbuntu which sets up in one stroke most things needed for the israeli crowd, i believe ubuntu will be the simplest most elegent choice. and please tell me FC5 is nothing like RHEL4.On 6/11/06, Nadav Har'El [EMAIL PROTECTED] wrote: On Tue, Jun 06, 2006, Adir Abraham wrote about [Haifux] Linux Day: Choosing the right distribution: Hi, As usual I'm calling for your help, to choose the right distribution for the crowd.My favorite distribution, and the one I use on my home computer, is FedoraCore.
