What I call a vintage kernel. You obviously have a beefy system with memory to spare. You obviously don't really care rebooting it. The logical conclusion: build some kernels and test it.

[Haifux] coding guidelines
Hi The company I work for just ran into the thing called ISO9000. It seems that one thing they want is to have coding guidelines for every programming language used. Right now we have C, shell, perl, python and PHP. For C we mostly work on some existing projects. For the rest, I figure that the kernel ones[1] are sane enough. The kernel folks also bothered writing a small script to check for most of them (checkpatch.pl). What would you recommend for coding guidelines for PHP and shell?

I have no simple topic for a lecture. Though I wonder if it's possible to do an OpenStreetMap[1] mapping session instead. Note that it cannot be done at the standard place because: 1. We need to add data. I suspect the Technion campus is already well-charted. 2. We later need to upload data and edit it. This requires internet connectivity. Generally I would expect this to be done in small teams where each team must have: * BigBrother: with a GPS device monitoring the location. That trace should then be later to his/her OpenStreetMap account for easier mapping in a different computer. * Mapper: Someone who knows what we actually need to chart (and what we don't have to / shouldn't) A team should probably include 1-3 other participants.

"תוכנה חופשית" מבית מדרשו של סטולמן ו"קוד פתוח" מבית מדרשו של ריימונד" אולי שואפים לדברים שונים, אך בפועל המושגים הללו קרובים מאוד. סטולמן דיבר על ארבע החרויות שתוכנה חופשית צריכה להבטיח[1]. יותר מאוחר נכתבה הגדרת הקוד הפתוח של מוסד הקוד הפתוח[2]. בפועל רשימת הרשיונות שקרן התוכנה החופשית מחשיבה כתוכנה חופשית[3] מסכימות כמעט על כל הרשיונות. הפצות שונות (הדוגמאות הבולטות הן דביאן ופדורה) יפסלו לעיתים גם תוכנות חופשיות משיקולי רישוי. לדוגמה: יש להן בעיות של הפרת פטנטים, או שהן דורשות תוכנות לא חופשיות לצורך בנייתן. לפעמים יש גם חוסר הסכמה בין הפצה מסויימת לבין אחת מהרשימות הנ"ל[5]. אז בקיצור, לא ממש משנה אם קוראים לזה תוכנה חופשית או קוד פתוח. במקרים רבים משתמשים באנגלית בראשי התיבות FOSS - Free and Open-Source Software או FLOSS - Free/Libree and Open Source Software. מבין רשיונות Creative Commons, כל רשיון עם דרישה של מניעת שימוש מסחרי או מניעת יצירה נגזרת משמעותה שהרשיון כבר לא מתאים לכללי התוכנה החופשית. 2. מידע על רשיונות בויקיפדיה בעקבות שאלה של מישהו: המצב בויקיפדיה העברית אכן גרוע (עזרה תתקבל בברכה). לעומת זאת, בזו האנגלית יש פרוט לא רע. 3. רשיונות פשוטים אני רוצה לחזור על ההדגשה: לא לכתוב רשיון שימוש. זה מסמך משפטי מחייב. עדיף להשתמש במסמך קיים. לדוגמה: http://en.wikipedia.org/wiki/WTFPL שימו לב שזו גרסה 2 של הרשיון.

I see nobody was interested in my off-topic suggestion, so, here it is again: I normally don't get to come to lectures. I suppose I'll come to this one. I realised that in all the Haifus meetings I don't recall anybody asking me to sign a OpenPGP key. Nor have I asked anyone to sign my key(s). I thus figured it might be a good idea to set-up key signing. After all, we are relatively well-connected. So, if you have an existing key, and you want it to be signed by others in the lecture tommorow: 1. (Prefferebly) send me the (public) key (gpg --export KEY_ID). 2. Bring a printed copy of the key's ID (gpg --fingerprint KEY_ID) 2.1. Maybe bring multiple copies of it in case (1) fails. See e.g. gpg-key2ps in the package siging-party (Debian/Ubuntu) 3. Brind a valid ID card (or driver's license or whatever, Should identify you, and include a photo).

Contiki has been used is a variety of projects, such as road tunnel fire monitoring, intrusion detection, water monitoring in the Baltic Sea, and in surveillance networks. Contiki is designed for microcontrollers with small amounts of memory. A typical Contiki configuration is 2 kilobytes of RAM and 40 kilobytes of ROM.

The mere fact that you wrote a work of art (if we stick with the terms
of the copyright law) does not in itself implies someone should pay
you. Someone should actually to distribute that work of art (and you're
the only one that can allow that).

This model has grave practical difficulties. It results in stupid
limitations such as you have to pay Akum for having the radio open and
playing songs in your shop, even though the radio station has already
payed Akum.
In fact, the creative commons licenses include a clause to explicitly
override Akum and its ilk from collecting royalties of various CC
liceneces.
Sourceforge (and other code hosting services: BerliOS.de, GNU Savana,
Google Code, Microsoft's CodePlex, and lesser ones such as various
-forge sites) provide a valueble service to me as a developer: I don't
have to worry about anything but coding. I can just code. I can also
easily let others join in.
Such an infrastructure costs money. It takes bandwidth. It takes
servers. It takes sysadmins to set it up, maintain it and provide
support.
The fact that Sourceforge exists has helped many people get their free
software projects in the air. I'm sure most of those are thankful to
SourceForge. I am personally (and I only used it for a few projects).
> The developer should be allowed to concentrate on what he is doing best -

SourceForge's hosting already does most of that.
BTW: there's also an option in SF to request donations. That said, ad
money or donations from a small project won't really pay for your time
as a programmer. I expect that to be roughly 10-100NIS a month (I'm just
making up numbers). It will encourge spamming projects, and it will
create a conflict between the vaqrious developers for who gets how much
("that's not fair. He's getting 5c and I get nothing!").

There are several reasons. Do you think you can actually make money from selling the software as a stand-alone product? Without support? If you make it free software you can still sell support. You're more likely to get good bug reports and even some patches. Furthermore, if you actually need that software to work well for you (e.g. to offer a better service to your clients) then making it free software reduces the development cost. It also reduces the deployment cost, because there's no licensing overhead and there's no inherent conflict between the developer and the user. For instance, it means people can get support from someone else, and hence they won't be left with a useless pile of bits if you're gone. It gives the software a higher value. > How can you earn money from opening the code and giving it for free? There are several possible methods.

That ^M is chartacter no. 13: \r, CR. As others have mentioned, this indicates a dos-formatted text file. Unix-formatted text files have only \n and the Macs have only \r for their own reasons.

In the basic layouts AD11 and AD12 remap only group 1. That is: they
only change they layout when you use a hebrew keymap. The Hebrew layout
is indeed a qwerty one. If you wish to provide a better one, please do.

[Haifux] dvorak and hebrew
Hi
To answer a question from the lecture:
I haven't tried it myself, but frankly I can't see any conflict between
the Israeli layout and the Dvorak layout. Try something like:
setxkbmap dvorak,il
One minor conflict is between the si1452 variant and dvorak with the
keys for {}. But:
* This is not the only layout that has conflicts with the si1452
variant. Practically any non-default layout has similar conflicts
* you use lyx and not si1452, right?
For reference:
/etc/X11/xkb/symbols/pc/dvorak
/etc/X11/xkb/symbols/pc/il
/etc/X11/xkb/symbols/pc/us
(Dan: any comments?)
If you want to experiment with dvorak, don't forget that X's keymap and
the console keymap are seperate. Be sure to configure both of them.

If that is what you need: 1. create a group of all the users that should be able to read and write to the partition (if there isn't such a group already) . I assume that this group is "users" 2. In the option field put: gid=users,umask=770 (rw and auto are default options, no need to mention them) And while you're at editing that fstab line, add 'utf8' as well, to avoid any unnecessary problems with Hebrew file names (assuming that your locale settings are sane) It is also advised that you change the '1' there to '2' , or even to '0' .

I recall somethingregarding a different nsswitch interface (/lib/nss* ) which is loaded via ldopen after readin /etc/nsswitch. I believe that this is why /bin/rpm is not statically linked on RH9.

How would you define exactly "problematic RPMs"? When you encounter dependency problems the problem can often be with packages whose dependecies seem satisfied. If there is a dependecy problem I would tend to handle it first (by enlargind/reducing the packages set) and only later handle other things. Otherwise I may install only part of the required packages for the upgrade I want. -- Tzafrir Cohen +---+ http://www.technion.ac.il/~tzafrir/ |vim is a mutt's best friend| mailto:[EMAIL PROTECTED] +---+ -- Haifa Linux Club Mailing List (http://www.haifux.org) To unsub send an empty message to [EMAIL PROTECTED]

Actually, qtparted seems to use ntfsresize (or the same code) for resizing NTFS partitions. I recently had exactly the same problem (fragmanted partition) with ntfsresize . ntfsresize gave me an error , and suggested to use XP's defrag. defrag turned out to be quite lousy: only after clearing out some more free disk space (~5GB instead of ~2.5GB) I could get it to defrag all the files. I still had one fragmanted directory, and a fragmanted MFT which seemed impossible to get reed of. Like Eli, I configured the syste,m not to use virtual memory. And still I got that error. The software is ntfs tools 0.51 (?) of knoppix 3.2 (22-9). qtparted seemed to have some problems with that partition. (and of course: resizing the filesystem is only the first stage. One has to be careful later when resizing the partition itself). -- Tzafrir Cohen mailto:[EMAIL PROTECTED] http://www.technion.ac.il/~tzafrir -- Haifa Linux Club Mailing List (http://www.haifux.org) To unsub send an empty message to [EMAIL PROTECTED]

Prosper is the most common latex-based lecture format. It can be used to
produce fancy slides (e.g. mulix's later slides, IIRC).
A simpler method is to use seminar (prosper is actually based on seminar).
Both can be used to create sort of "animations". (it is actually more
straight-forward with prosper).
Hebrew support can be easier with seminar, because with prosper you have
to mess with the postscript issues. Another shortcoming of prosper is that
the dvi preview isn't useful. But the atvantratge of the ready-made
layouts is actually quite huge. Should I try to add a hebprosper style to
the hebclass of ivritex?

It is being actively used with pdflatex, AFAIK.
But so far I haven't got around to configure it on my system...
