Also, what happens if I add a link from my site to:

Works like a charm ;)
2. I'd rather not have a black background. Can it be the other way around?
A more practical consideration: what happens if someone tries to print
this page? (and do you care?)
CSS allows you to specify a different color for printing than the default
for screen. See - CSS is not moot.
For example, the CSS file for my homepage contains:
BODY {
color: #55;
...
}
...
@media print {
BODY { color: black; }
...
}
So that the default color for everything in the BODY (i.e., everything)
is gray, but when printing (@media is print) the color black is used
instead.
3. Please switch the HTML to X/HTML + CSS.
And break older browsers?
Forget about X/HTML, just use HTML 4 and CSS. The only browser that can
break is broswers like Netscape 4, which pretends to support CSS but does
so incorrectly. But *nobody* should be using Netscape 4, or some old versions
of IE, right?
As for CSS: the main reason for using it is king of mute. See your next
point ;-)
Note that CSS has nothing to do with dynamic pages, animation or other
bells-and-whistles. It is just a mechanism to separate the formatting from
the content, which as a side-benefit allows people who don't want to see
your design (because they're unable, like blind people, or because they
don't want to, like Lynx or cellphone users) to see only the content.
It is noot moot (and certainly not mute ;) )
By the way, the current HTML code in that page isn't half bad - it mostly
avoids formatting tricks, so it already should look good to Lynxers or
blind people as it is - it doesn't need CSS for that.

I think both Stallman and his competitors would be annoyed by such a statement: Stallman would tell you he invented free software, not open source (!), and his competitors would tell you that well before the 1980's a lot of software came with source (heck, the only way to get Unix was probably as a source distribution), but this source was not free (like Hannuka candles, you could look at it but not make use of it, i.e., you couldn't change and redistribute it). Slide 3: You say Nowadays, most of the big hardware vendors release also Linux drivers. That's nice, but is it really true? I never (not even once) found a Linux driver on the diskette/cdrom accompanying a hardware product. Most of the drivers I got of the net (for my HP printer, laptop's modem, sound card, etc.) were written by private individuals by reverse engineering or by using some unsupported code released once by the hardware company (in the case of the lucent modem on my laptop).

(I can show that, but it seems like Nadav is the natural selection). I'm choosing Bask and not zsh because bash is the de-facto shell. And tcsh is pretty much useless on the command line. I wonder how that will help to the *newbies*... ? There are two schools of thought about the Unix (and Linux) user interface. One believes that the command-line interface (and shells, xterm, editing rc files, environment variables, and everything that go with that) is an old- fashioned, inferior, difficult, non-friendly user-interface which should go away as soon as graphical applications are written to replace each one of them. The second school (to which I belong) thinks that a command-line interface has explicit advantages to anyone who wants to use the computer as a serious tool - it allows to *easily* automate repetative tasks, combine actions of seperate programs in intuitive ways (once you learn that intuition ;)), allows a What-you-see-determines-what-you'll-get instead of the Windows What-you-get-depends-on-10,000-things-you-don't-see. People of the second school do not believe that using a shell is an advanced thing, but rather an idea, a way of thought, that should be taught to newbies right from the very start. Before the era of GNOME and KDE, all Unix/Linux books started by teaching basic shell. If newbies could handle it then, they can also handle it now. Let's face it - most of the applications you want to show to newbies (e.g., KDE, koffice, gimp, etc.) are cheap Windows knockoffs. Since most Israelis don't care about Windows' price (they pirate it anyway), the only way to convince them (and I'm talking about people interested in computers, not secrataries who need to type letters) to try Linux is to show them some interesting things it can do and Windows normally doesn't. I'm saying Windows *normally* doesn't, because as Orna already mentioned it's not hard to get LaTeX, zsh, and most other Linux applications to run on Windows too. -- Nadav Har'El| Thursday, Apr 11 2002, 29 Nisan 5762 [EMAIL PROTECTED] |- Phone: +972-53-245868, ICQ 13349191 |The two rules for success are: 1.

Orna. Isn't PVM a model for parallel-processing and synchronization that can be used on Beowulf clusters? From what I understood, forking or POSIX threads should achieve the same effect. Please tell us more about it. PVM (Parallel Virtual Machine) is in essance a message-passing library, a way for processes running on different computers (part of a cluster of identical or different machines, not just a Linux cluster) to communicate easily. It is used to write parallelized programs to be run on such clusters. The Virtual Machine metaphor allows you to spawn children which will be run on remote hosts (compare this to fork() which only runs on the local host) and communicate easily with your children (or other processes running on the same virtual machine). Nodes (machines) can be added or removed from the virtual machine at any time, even when a program is running on it. PVM's main competitor is MPI, the Message Passing Interface. MPI puts less emphasis on heterogeneous clusters and on a flexible virtual machine (MPI 2 should start to support these things), and more emphasis on very efficient support of homogeneous clusters and MPPs, including supporting dozens (even hundreds) of specific communication patters which might have special hardware optimization on certain MPPs. PVM has nothing to do with POSIX threads. It is a programming paradigm for clusters or MPPs (Massivly Parallel Processors), where each processor has seperate memory and message-passing is needed, and not on SMPs (Symmetrical Multi-Processor, where processors share memory) where POSIX threads is often used. -- Nadav Har'El| Tuesday, Feb 12 2002, 30 Shevat 5762 [EMAIL PROTECTED] |- Phone: +972-53-245868, ICQ 13349191 |Time is the best teacher.

The core of MOSIX are kernel-level, adaptive load-balancing and memory ushering algorithms that are geared for maximal performance, overhead-free scalability and ease-of-use. These algorithms are designed to respond on-line to variations in the resource usage among the nodes by migrating processes from one node to another, preemptively and trans-parently, to balance the load and to prevent memory depletion at any node. The MOSIX software allows a cluster of PCs (workstations and servers) to work cooperatively as if part of a single system. MOSIX uses competitive algorithms for on-line distribution and redis-tribution of the workload and the resources in order to improve the overall performance of a computing-cluster of any size. MOSIX conve-niently supports a multi-user time-sharing environment for the execu-tion of both sequential and parallel tasks. The talk gives an overview of MOSIX for Linux and its resource sharing algorithms. The lecture will take place On Thursday, 30.1.2002 at 12:30-14:30 in Room 353 Electrical Eng.

Zsh has long (read, about 8 years, at least) had the most sophisticated completion system of any of the shells. It was quite easy to get it to complete only *.ps files for gv, only process numbers for kill (except after a minus, where signal names are completed), and much much more complicated stuff. In fact, this was probably the biggest reason that got me to switch to zsh in the first place. In Zsh 4 (Redhat 7.2, for example, comes with zsh 4.0.2), the entire completion system was reworked, to be even more sophisticated (it is now programmed based on shell functions). But the even more exciting news is that it comes by default with the most complete completion you can imagine, for any unix/linux utility you could imagine (300 of them!). It completes filenames, special parameters, username, process numbers, and everything you else you could imagine wanting to complete. A few examples: $ gvTAB file1.ps files2.ps.gz $ gv -TAB -ad -font -nopixmap -scalebase -antialias -foreground -noquiet-seascape ... $ gv -foTAB -font -foreground $ kill -UTAB -URG-USR1 -USR2 $ kill 18TAB 1871 pts/500:00:00 zsh 1888 pts/500:00:00 zsh 1889 pts/500:00:00 ps $ chown nTAB named nfsnobody nscdnyh newsnobody ntp and so on. To get all this wonderful magic, all you got to do in a good installation of zsh 4 is: autoload -U compinit compinit (It's probably in the zsh manual. I don't know why it's not the default.

It isn't a major leap ahead of Redhat 7.1, but I believe it is worth the upgrade. In any case, does RH 7.2 supports creating and installing on ReiserFS partitions? Redhat 7.2 can make reiserfs filesystems (using mkfs or mkreiserfs), mount them, and so on, but there is no convenient way (as far as I know) to install Redhat 7.2 on a new disk while making the newly created partions ReiserFS. If you want ReiserFS for its journaling capabilites, you might consider ext3 (which is prebuilt into Redhat 7.2 and also to the latest Alan Cox kernels) - Redhat's installation lets you create new partions formatted as ext3, and even change existing ext2 to ext3 while upgrading (this, by the way, is a trivial operation because ext3 is a relatively simple extension to ext2). If you plan to use Reiserfs on Redhat 7.1, however, watch out: their kernel has a bug which makes umount of reiserfs partions hang in an uninterruptable state - which is extremely annoying. Redhat 7.2 does not have that problem.

Re: [Haifux] regarding the 1st lecture
On Mon, Oct 15, 2001, Orna Agmon wrote about Re: [Haifux] regarding the 1st lecture: form a cluster, and why i prefer linux to windows for that: i dont have to install linux with the window manager, i can minimize the size of the OS, and use the disk space and the memory for the program itself. i can install and upgrade many computers easily, not having to work on each of them manually. i can controll these computers easily from another computer using xterminals. Nadav, if there is anything you would like to add... Yeah, that's about it, but let me expand on it: For most of these things, Windows devotees can come up with counter-examples: you can get software on Windows that does remote-administration, remote terminals, and so on. However, these things on a Windows system will cost you in at least three ways: 1. More manual work for installation and/or upgrades, to do it for several packages. 2. More hard-disk and memory waste (translates to money because you need to buy more memory, for example). 3. Much more expensive. So the bottom line is that the Linux solution will be cheaper - even if you include the supposed cost of system administration. But as you said, When you consider the strong points and foci (yes, that's the plural of focus ;) pronounced fos-eye ;)) of both Windows and Linux, it becomes obvious which one suits cluster computers (e.g., 10-100 PCs for things like server farms, compile farms, computation farms, etc) better, even if you don't consider the cost: 1. Window's strong side (and the reason why everyone buys it) is graphical, interactive applications. However stuff like MS-Word, DivX players, drivers for cheap winmodems or state-of-the-art games are completely irrelevant to computer clusters. 2. Linux's strong side is running non-interactive programs that you compiled, perhaps by remote control. This is exactly what you need for a cluster. 3. Linux comes with a compilers, debuggers, and everything needed to create your own programs (as opposed to buying ready-made programs). In Windows, you'll need to buy more software. 4. Linux makes it just as easy (if you can call it easy) to administer systems remotely and locally. In Windows local administration is supposedly easy (just move your mouse around!) but would anyone care to repeat it a 100 times? 5. Linux is more stable and rarely ever requires deliberate reboots. This is extremely important in a cluster: if every computer crashes every 100 days, on a 100-computer cluster this would mean one crash every day! 6. Linux is more modular: you easily install only the parts of the Kernel, O/S and utilities you need. In Windows this is much harder, if at all possible (try to install Windows without any graphics support at all...) 7. Parallelization libraries (pvm, mpi) and setups (mosix, beowulf, etc.) have been designed and polished on Unix and Linux - but are less polished on Windows.

Moreover, you might get them scared if you start talking about backups :) The first time I accidentally erased over half of my files was roughly 6 months after I started using Unix. At that time I was a complete computer novice, and never even thought of making backups for myself. Only A year later, in 1985, the timesharing computer that I had used (a VAX running ATT 8th edition research UNIX) got a central backup on a 3 gigabyte WORM (write once read many) optical disk, but that was too late for me... Of course, after that incident I never forgot to backup again. Ever.. Using various approaches, but none as simplistic as your cp $I $i.bak example.

But you also need to make backups on other media and/or computers, because disk failures, cracking, and other types of crimes and natural desaster do happen, unfortunately. So it's good to recommend backing up, but it's not exactly a Linux specific issue. Of course the fact that there is no garbage can or undelete in Linux makes deletion very dangerous in Linux. The specific command that lost me half my files back in 1984 was something like rm xy * note the extra space character :( I meant to remove all files starting with xy, but it removed everything.

If C and shell were the same thing, there would have been no reason to learn them both anyway! Do you know what? I learnt sh (bourne shell) and C when I was 10, reading a book in English when I barely knew English, and knew nothing about computers. If I managed to do it, so can the students in the Technion at the age of 20. Give them a little credit - they are not total idiots :) As someone already mentioned, learning two different syntaxes is actually a good preperation for a world filled with dozens of languages with different syntaxes. i think the technion should not be teaching c as a first language, but rather c++ or even java. This is a seperate debate, and I personally don't agree: I think C++ is a much more complex language than C, and it's much harder to write *good* programs with it (i.e., a program which an expert can look at it and say: yeah, that's a good way to code what you wanted to do!). I've seen too many examples of people writing bad code in C++, which is even harder to fix or understand than bad code in C. If C++ is used as some sort of C + overloading tricks + a small class instead of a small struct, I'd rather them teaching C first. in contrast, i dont mind the technion teaching csh. it's a useful tool. No it isn't. It's as a useful tool as a worn-out screwdriver: when you go out to the outside world, once in a while you'll need to use a screwdriver that has been worn-out, and you'll need to settle with it. But it's no reason to learn only about worn-out screwdrivers. Usually you have the choice, and you need to know how a good screwdriver looks like, where to get one, and how to use it, and not go into a hardware store saying I get confused with all those brand-new screwdrivers - we didn't have those when I was studying. Do you have some crappy worn-out one?. csh is useful. there are a lot of csh scripts out there (who knows how many of them were written by technion graduates? ;)) I've never seen a csh script written by someone who actually knew what he or she was doing. Sorry... It's useful to read csh (and I do), but never to write it. specifically asked for a C-shell script, two students over-blown their script just so they can handle directory names with whitespace. Needless to say, in the bourne shell this is a non-issue which can be easily solved. there's always a better tool. so what's your point? betterness of tools is not a linear ordering. You can't say csh bash perl C++ lisp Because usually when you take a pair of tools (e.g., bash and perl) each one is better in different things. Perl is not a convenient replacement to sh when it comes to writing short scripts with mostly pipelines of existing utilities, while bash is not a convenient replacement to perl when it comes to complicated text and number handling. However, in this case clearly csh bash, in every case (can you show an example where csh is better than bash?), which is why you can teach csh as some archaic language (like Latin is taught), but it should not be taught as the tool of choice. Tools which are always inferior to others should go the way of the dodo.

CSS, Cascading Style Sheets, is a standard (look at w3c's site for a complete document on it) for defining how HTML elements should look like, e.g., you can say that all H1 headings should be 1-inch tall and red, that all paragraphs should be 500 pixels wide and indented, that lists should use some gif image instead of the usual bullet, and much much more. This way, the site looks exactly like you want it to look in all modern graphical browsers (both Mozilla and IE have almost complete support for CSS 1, and some of CSS 2; Netscape 4 supports CSS 1 but is somewhat buggy), but textual browsers (such as lynx), and more importantly - browsers for the vision impaired (blind, dyslexic, etc.) will know exactly what the author meant, since the author uses H1, LIST, etc., rather than amorphous tables and graphics. You can see an example use of CSS in my homepage, nadav.harel.org.il. and in particular my pets' homepage, at http://nadav.harel.org.il/homepage/doggie.html Not a pinnacle of design, but a good example on how to create a site that is not bad-looking (I'd like to think) on a graphical browser, and still looks great with lynx. It's very hard to create a page that looks this good in both Mozilla and lynx without using CSS - try it and you'll see why. -- Nadav Har'El| Saturday, Sep 15 2001, 28 Elul 5761 [EMAIL PROTECTED] |- Phone: +972-53-245868, ICQ 13349191 |Enjoy the new millennium; it might be http://nadav.harel.org.il |your last. -- Haifa Linux Club Mailing List (http://linuxclub.il.eu.org) To unsub send an empty message to [EMAIL PROTECTED]

The trouble with all this is while it'll look great on Mozilla / Netscape 6, Internet Explorer and Konqueror, it'll be totally broken on Netscape 4. I usually urge people to forget Netscape 4 as if it was a bad dream, but some Linux users with slower machines might complain. Well, Netscape 4 is supposed to support CSS 1. Unfortunately, it has so many bugs that almost no page with CSS will look the way the author intended on Netscape 4. There are three ways to solve this problem: 1. Ignore Netscape 4. This is what I do - Mozilla is available (as far as I know) on any machine for which Netscape 4 was available, and it's free. This is a good solution for my homepage, but a politically-incorrect solution for an important page, at least while people still use Netscape 4. 2. Try to use only CSS styles that work on both Netscape 4 and the standard- compliant browsers (such as Mozilla and IE). This is not easy, and I don't recommend it. 3. CSS stylesheets normally come from a seperate file. You can make this file a CGI script (or whatever) which sends one of several stylesheets: a Netscape one if the user is using Netscape, and a different one for any other browser (including Mozilla). Many sites using CSS use this approach. (BTW, Nadav, the FONT tag and the ALIGN attribute are deprecated :) Well, I guess you're right, in HTML 4. They removed many of the attributes which they now recommend to set using styles and stylesheets. But no browser in existance accepts *only* HTML 4 (these attributes were perfectly legal in HTML 3.*), and old habbits are hard to break... -- Nadav Har'El| Saturday, Sep 15 2001, 28 Elul 5761 [EMAIL PROTECTED] |- Phone: +972-53-245868, ICQ 13349191 |A mathematician is a device for turning http://nadav.harel.org.il |coffee into theorems -- P.

ADSL setup on linux (consists of me reading the HOWTO out loud :)) I'm not very interested in it, mainly because I have already set up ADSL at my home using your HOWTO. It was pretty much straightforward. My biggest problem had been finding a driver for my Ethernet card. Well, I am... I don't have ADSL and will not have one in the forseable future (a modem connection costs me about 1/10 the price, and I don't mind the slowness - I'm not using Microsoft's .net architecture :)). Nevertheless, it might be interesting to hear how ADSL, PPPoE/PPtP, and all the related stuff work. I'm sure I can read all of it from HOWTOs (I already know some of the material), but as usual I probably won't do it until I need to use ADSL myself. 2. ADSL fundamentals (how xDSL technologies work, and ADSL in particular, and the PPTP protocol) Perhaps interesting, but then again, not particularily related to Linux. I personally do not find too much interest in it. AFAI can see ADSL works and works well, whether on my Linux or on Win98 and that's all I need to know. Perhaps it is not specific to Linux, but so isn't Corba, TCP/IP, Lambda calculus, and other lectures we've heard... I think the question should be is it of interest to inquisitive Linux users - not whether it might also interest MS-Windows users. 3. ADSL connection fundamentals (how the connection is made, RAS, NAS, why we all hate bezeq, etc) I'm not too interested in such things.

I am posting this lecture here, to see if enough people would like a lecture about the Haskell Programming Language. This lecture would be as part of the Haifux standard lectures, not as part of the Perl series or anything. I'd be very interested in hearing such a talk. Haskell is one of the languages I've been promising myself to learn, but never went ahead and did it. As a side note I should mention that Guy Keren said that if I am to give a lecture about Haskell, he is going to give a lecture about programming using vi macros. I hope they are vim macros, becuase I use gvim. ;-) Why not write a Haskell interpreter using vi macros? :) I once saw a Forth interpreter written in Logo, and an assembler written in Basic, so a Haskell interpreter in vi is a step in the right direction ;) By the way, Vim added tons of features to its macro language, to the point that it now looks almost like a "real" language, with functions, variables, and everything. That doesn't count! Purists write in pure vi :) I once saw a towers-of-hanoi animating macro in pure vi, but I don't remember where I found it. Perhaps in the original vi package from Joy, I don't remember...
