Re: some help in technical solution
Here is another very cheap solution: http://www.pjrc.com/teensy/ The small board has 25 digital I/Os and 7 analog for $16, and the larger one has 46 digital I/Os and 12 analog. If your competitors are close enough you can use one board for multiple inputs. Since you need to hook key presses which is measures by tens of milli-seconds in the best case, I believe long wires would pose no problems (propagation delay and bandwidth are not a problem). They even have ready made examples of emulating a mouse, a keyboard, a generic HID device, etc. Shipping costs would be $10-$16 on airmail, depending on package weight ($16 is for 2 pounds, about 0.9Kg, enough for at least 3 boards).

Re: some help in technical solution
I think that analog DAQ with 30 channels would be an overkill for such an application. If you need to give each competitor 4 options, why not choose between one of the following options: 1. 120 digital channels (5 digital DAQ modules at 24 channels each) and provide each competitor with 4 channels, each one connected to its own pushbutton. 2. If you prefer to build 30 4-2 encoders, each getting inputs from 4 pushbuttons and providing 2 digital outputs, then you'll need only 60 digital channels (3 digital DAQ modules, with 12 digital channels to spare). Of course, the final choice involves price tradeoff between: - Analog DAQ with 30 channels + 4-pushbutton with resistors module - Digital DAQ with 120 channels + simple 4-pushbutton module - Digital DAQ with 60 channels + 4-pushbutton with encoder module I assume that data processing speed is not a limiting factor. --- Omer On Wed, 2011-04-06 at 15:54 +0300, yosi yarchi wrote: Hi This is interesting idea.

Re: some help in technical solution
Unless I am mistaken, the USB specs stipulate that it shall be possible to connect up to 127 USB devices to a PC. So what you want to do should be doable. However I don't know the chances of it exposing bugs in the Linux USB subsystem, as it is a rare use case. However, if you are providing hardware to the competitors anyway, why not issue them a WiFi enabled device, and then have your server collect information via TCP/IP (such as by having them surf to a Website which does the answer collection). --- Omer On Wed, 2011-04-06 at 07:44 +0300, yosi yarchi wrote: Hi all I need application that will be able to collect and process inputs from 30 (!) competitors, and will display the results very fast.

Kiwix project is looking for help
Hi, I'm publishing this mail on behalf of the wikimedia foundation which tries to find people who are interested in joining the Kiwix project: Kiwix is an open-source, cross-platform, free software offline reader for Wikipedia and other collections of Web pages and related images. Kiwix is always looking for new developers. We mainly need people with skills in C++ and with the GNU compilation tools. Kiwix is also based on Web technologies as, for example, javascript or CSS, so a good Internet/Web understanding is also essential. The code base is not really complicated. Kiwix uses the best existing software libraries in different domains as fulltext search, unicode transformation or template rendering. We think this is pretty easy to dive in the code. Currently we are working on the 0.9 release and most of the work is already done, but there is still a lot to do for the 1.0 release. This will provide an internal content download manager. The solution will use the best of P2P technologies, so, if you are interested in mirroring strategy, Metalink, Bittorent, magnet, etc., contact us at http://www.kiwix.org p.s. This is not a job offer, we're looking for volunteers. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
Help with script
I am looking for someone to mentor me, help me, or work with me on the following, non-marketable project. This is NOT a job offer, but a request for help. If any money comes out of the project, I will gladly share it with people who help me, but I doubt anything will. So here is a description of what I want to accomplish: Many years ago, I resolved to read the bible (old testament) in its entirety, in Hebrew/Spanish. I purchased a dual language bible, La Biblia, and start the journey. The goal was to learn Spanish, and also become acquainted with the old text, only bits and pieces of which are taught in any school, even a religious one. Carrying a bilingual bible is literally a heavy burden, scares away the chicks and everyone else except fundamentalists and weirdos, which did not help. I got stuck somewhere in the second book when too many names stumped me. I still read a page now and then, but at this rate it will take me 543 years to finish. Fast forward 20 years, we now have a tool perfect for reading one line at a time - the new Kindle! So I am thinking why not create an electronic version of the same document - 2 bilingual bibles, Hebrew-Spanish and Spanish-Hebrew, verse by verse. Maybe even with punctuation marks, though that is not a necessity. I can find copyright free web pages. In Spanish I can get the whole bible as a single file. In Hebrew most sites are arranged book by book, but that is fairly easy to combine into a single file manually. I would like to write a script, preferably in python, that would read the files, parse them into a series of sentences, and recombine them as a bilingual file, one verse following the other. Hebrew/Spanish and Spanish/Hebrew. I am not a programmer, but I can probably create a script with guidance. Working with a knowledgeable individual would eliminate enough of the learning curve for me to make it a reality. If I were to do it from scratch, it will be so low on my priorities list that it would take years to get to it. If we get this done, I would post it somewhere as a freely available document, of course. As for the commercial part - if we get this text processed, I will considering offering it as a Kindle book on Amazon, and also maybe converting it to PDF. As far as I know there is nothing like that on the market, though someone is selling dual language bibles in English and a number of other languages on Amazon. Anyone interested in helping with the project, please let me know.

Re: Help with script
I am not a script wizard, but I think I may know of a way to cut down a lot of the work. Calibre (http://calibre-ebook.com/) is a FOSS library tool. It allows the user to import books in many formats, including plain text and html. Another FOSS program called Sigil (http://code.google.com/p/sigil/) allows the user to easily create, edit and modify epub formatted ebooks (creating a title page, changing text format in a GUI editor, making a table of contents...). What I would do would be to save the html (or plain text) files from the internet in a single folder, then import that to Calibre, then use Calibre's tool to convert to an epub book, and use Sigil to add the finishing touches. Between the two, and with freely available text from the internet, I think you can get the job done a lot easier, without writing a single script.

How the printers are connected to the print server and what is the need ? 1) if each client need to be a single admin for a signle printer this is one thing - 2) if each client need to be able to add /remove a printing job to some queue (on one or more printers) 3) some policy enabled printing (billing, max amount of pages / size / print jobs / account etc ...)

I'm not an x86-64 expert, but it implies from intel docs that 64 bit
immediate values are supported only for the MOV instruction:
http://www.intel.com/assets/pdf/manual/253666.pdf
---
2.2.1.5 Immediates
In 64-bit mode, the typical size of immediate operands remains 32 bits. When
the
operand size is 64 bits, the processor sign-extends all immediates to 64
bits prior to
their use.
Support for 64-bit immediate operands is accomplished by expanding the
semantics
of the existing move (MOV reg, imm16/32) instructions. These instructions
(opcodes
B8H – BFH) move 16-bits or 32-bits of immediate data (depending on the
effective
operand size) into a GPR. When the effective operand size is 64 bits, these
instructions
can be used to load an immediate into a GPR. A REX prefix is needed to
override
the 32-bit default operand size to a 64-bit operand size.
For example:
48 B8 8877665544332211 MOV RAX,1122334455667788H

I notice that no other nation in Europe has this Infrastructure/ISP dichotomy. Furthermore, the next time that there is a problem how can I check if the issue is with the infrastructure or with the ISP? 1. I used both Bezeq and Hot and I prefer Bezeq. Hot's service is really terrible. I'm currently connected with Bezeq and Bezeq International, and I use Gmail + Google Apps as my email provider (not Bezeq International). 2. The law in Israel forbids Bezeq and Hot from connecting people to the Internet without using ISP, since they are both monopolies. You need to have two companies - either Bezeq or Hot + an ISP. But you can make a deal with an ISP to pay for Bezeq or Hot - that's what I am doing with Bezeq International. 3. I'm using Windows with a dialer to connect to the Internet. If you use a router you can configure the router to dial up for you. I really don't know how you can connect without a dialer. 4. When you use a dialer, if you can't connect you get an error message. Tech support people can understand this error message to see where is the problem. You also have lights in your modem, they are also used to track problems. You can contact either your ISP tech support or your infrastructure - I usually call ISP first. 5. I know Bezeq had once options to connect with an ISP without opening an account - you pay per minute but it's very expensive and I don't recommend doing it. Even then when I had technical problems and called Bezeq, they told me to call the tech support of my ISP. 6. Maybe Hevrat Hashmal will start competing with Bezeq and Hot, then we will have 3 companies which means more competition - prices will go down and speed service will improve. 7. An ideal state will be that a company will not need permission from the government (ministry of communications) to connect people to the Internet (or to phone fax). Then we can have hundreds of companies with competition - prices will go down and speed service will improve a lot. But if you live far away from the center you will have less options. Still I think this is the best solution. Anyone wants to change the law?... 8. Next time don't wait two weeks. Switch to Bezeq. 9. By the way, by giving Hot permission to connect you to the Internet, I think you must have an account with an ISP, pay the ISP and you are using the ISP - but directly without a dialer.

If you don't have Internet access at all, and OTHER 012 dialer-less users do, then I would say the problem lies within Hot. As you were correctly told, in dialer-less (also dubbed MPLS-mode), Hot simply assigns you an IP address from an 012's IP range that gets exported to them, and they are the one actually connecting you to the Internet. If you have Internet, but it's slow, etc, then this can be a problem in either one of them (usually something between you and the CMTS...) - or congestion / routing issue within the ISP. So it really depends on what do you mean when you say not having Internet access. Surely, if she didn't have access _at all_, that didn't happen to all 012 MPLS users (or the media would be all over this and you would know). The modem having the lights on is meaningless. Hot can say whatever they want. Recently I had some serious trouble with them, due to frequencies filter that they've placed on my cable, to stop me from receiving their analog broadcasts, after I disconnected from their TV service (in favor of Hot, which is why it is so ridiculous that they did...). During those troubles, their modem completely lost the ability to catch signal from the network, and the lights were still all on, as if all is good. A power cycle of the modem revealed that it cannot get back to that state :) Anyways... 012 really can't do anything if it's not a global problem that they have. They indeed have 0 control over a single user in that mode of connection. Either all the users in your network pool has a problem, or none of them has, as far as 012 is concerned. This assertion is of course correct to all connections at MPLS-mode, not only via 012.

FWIW, I have never used a dialer with a broadband connection, and I have never heard a support person saying anything along the lines of since you do not use a dialer we cannot help you. 012 sees the modem, so they say the problem must be with Hot. They have a point, see below. Furthermore, at 012 they inform me that it is Hot, not 012, that is providing the internet outside because there is no dialer. They say that they gave Hot permission to connect me directly to the internet this way. So if Hot can provide connections out, then why do we need ISPs at all? AFAIK, your ISP is responsible for giving you the logical access, i.e., providing you with an IP address from their pool, username, password, mailbox, etc. The infrastructure provider (Hot in your case and mine) are responsible for actually running the DHCP service that provides you with the right address and routing you to the outside world. They do this if they have the appropriate information from the ISP (you are a customer with such and such contract, you use direct DHCP, you have paid, etc., etc.). The reasons for the division of labour are probably legal and can hardly be relevant.. Furthermore, the next time that there is a problem how can I check if the issue is with the infrastructure or with the ISP? I always call Hot first since they are the ones who run the basic services. I think just once in recent years they bounced me to Barak - I forgot the exact reason but it sounded plausible, and the Barak's techie chuckled and said, Huh, they are right for once, would you believe it?... After two weeks of my mother-in-law not having internet access, What exactly does this mean? Does she get an IP address? Does she get an IP address from the ISP's range? Is she routed to the outside world? In my experience, being specific about the problem helps a lot. Next time you call Hot take care to gather the information and present them with as detailed and focused description of the problem as you can. E.g., I powercycled my modem, it is synchronized, but DHCP gives me X.X.X.X rather than Y.Y.Y.Y that I expect. I traceroute www.google.com and it stops inside your network. It looks like you guys don't assign me my ISP's address and don't route me to the world - could you have a look why?. Once you have formulated the problem in such terms - and assuming you appear knowledgeable and polite and good-humoured - it is difficult for them to just wave you off. In my experience, they are not so bad. I am usually more frustrated with losing the service in the first place and waiting on the line and waddling through the menus than with the support personnel themselves. -- Oleg Goldshmidt | p...@goldshmidt.org ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Re: Help me understand connection to internet: Infrastructure and ISP
I have been pursuing an Internet problem for the last two weeks until its apparent solution last week. It was classical - Packet Loss. Hot blamed Bezeq Int. and did nothing about it, I have had to prove (using Bezeqint support personnel) that the problem was Hot's. It was very tiresome, and I consider sending them a bill for my hours under the title assistance with solving Internet connectivity problem. I don't think they will pay, but it could be interesting to see the response it might provoke there. I use Linux, and I use a dialer. Whoever claims you have to use MPLS (aka - no-dialer) for Linux is an idiot who doesn't understand the infrastructure. I use L2TP, as can be described here (works for modern distros as well): http://run.tournament.org.il/cables-connection-in-israel-for-linux/ I have written it :-) It allows for easier troubleshooting when it comes to support personnel, given you understand the actions required. BezeqInt were OK, regarding the waste of my time, as I had explained what I was doing, and gave the (true) impression I know what I'm doing. Hot, on the other side, had a great service. They had spent hours with me. It's a great service, where it can be measured on the level of service, but they are technically inadepts, who should be kept far away from computer equipment. I refer their technical teams, of course - Their infrastructure teams, especially, and their tech support teams. They are like baboons with keyboards, and most of their actions are based on random it succeeded before so let's do it again methods. However, since Bezeq don't supply NGN near my home, I am stuck with Hot for the next year, most likely. When using MPLS, try to use traceroute, and check if you get packet loss to your default GW. This is within Hot's domain, still. Onwards, it's Bezeq Int. You can use their speed tests, and other international speed tests to test the connectivity. You can check DNS, with their DNS server, or with free DNS servers on the net, such as 8.8.8.8 (google. Will supply service). Hope it works for you better in the future.

Hi,
Yesterday my harddrive had an inconvenient event: when I was using a d-i
from testing I accidentally overwritten on of the pv's connected to the lvm.
I started to panic and found myself making more damage by running vgreduce
--*remove*-*missing* since in one of the rescue files it noted this is the
way to fix it.
the config was :
/dev/sda7 pv0

KDE Jewish/Israeli holiday files: the dev needs our help!
From the Korganizer dev: For 4.5 however things are changing. The KDE holiday region files now support any KDE calendar system, including Hebrew, so I will be adding new separate files for the Israeli civil holidays and Jewish religious holidays in both English and Hebrew. We can even have separate files for Orthodox and Western holidays if needed. I need to get moving with those files, any help would be appreciated :-) basically we need to decide how many different files to split them into (Civil/Religious, Western/Israeli, English/Hebrew, etc) so users can choose exactly what they want to display, select which holidays go into each file, define what the rules are for each holiday, then make sure the library can cope with the rules. So, first question: how many files are needed? I personally think that a Jewish file (for religious holidays) and an Israeli file (for national holidays) would be enough. As we are a small people, I would even accept an argument that they should both be in a single file.

If you visit the holidays page of the Jewish Genealogical Society http://www.jewishgen.org/jos/josfest.htm, you will see that they give the date for the first day of multi-day holidays. Once one knows the date of the first day of Pesah, for example, he can compute when the second seder is. For cases like Shmini Atzeret, if should not be difficult to provide a switch for Israel/Diaspora, though it ought to be enough to provide the first day of Sukkot, and rely on the user to figure it out. He knows whether he lives here or abroad. Look at the preferences window in the Firefox addon Hebrew Calendar (which even counts the Omer, calls out the Parasha (with an option for Israel or Diaspora). If KDE wants expertise, they should contact the developer of Kaluach kaluach.net. They keep me posted by email about both Israeli and Jewish holidays.

You didn't attach the script, but basically forging mail on the Internet is trivial. The key point to understand is that SMTP, the simple mail transfer protocol, has absolutely no authentication mechanism for the From address. If I send mail from n...@math.technion.ac.il, my host simply writes the line MAIL FROM: n...@math.technion.ac.il as part of the SMTP session with the receiving mail server. It could have just as easily wrote presid...@whitehouse.gov. Traditionally, on Unix hosts, the mail program such as sendmail automatically fills this address, and only root can override it (sendmail -f...). But this is completely irrelevant protection, because somebody can use any other software, or even manually doing direct SMTP connection (telnet host 25), to send mail pretending to be from anyone. When I was in a Technion freshman, circa 18 years ago, I used to amuse my fellow students by sending them mail from presid...@whitehouse.gov :-) Anyway, even though the From envelope and From: header can be easily forged this way, something you can't avoid is the Received: trail - the mail will contain a list of IP address which relayed this message, including your host - the host that initiated that SMTP session and pretended to be presid...@whitehouse.gov. As you saw, getting around this annoyance is easy - all you need to do is find a host that will agree to take any crap that you send it and spew it out to your choice of address. socks proxies, tor, and so on, let you do exactly that - you can initiate a connection to some mail server port 25, but the server will get the connection through some intermediate server(s) which will hide who you are. Trying to track down the origin of such connections is quite hopeless unless this guy makes a big mistake. But filtering them is somewhat easier. Perhaps the most reliable thing you can do is to blacklist email arriving through any known socks proxies or similar open machines. Numerous blacklists exist to this effect (e.g., http://www.us.sorbs.net/) and scripts to process each mail and filter out the suspicious ones.

We need someone who can take the two lists (Google will export as CSV or XLS, I think) and make up a script that can cross the lists, tally and show if the people currently in the building give a majority for or against the law.

Well done, you nailed it. Placing an explicit call to exit for the child process solves the segfault. I hope you used _exit() and NOT exit(). The man page on my system for vfork says (read carefully, at least 3 catch you): vfork() differs from fork() in that the parent is suspended until the child makes a call to execve(2) or _exit(2). The child shares all memory with its parent, including the stack, until execve() is issued by the child. The child must not return from the current function or call exit(), but may call _exit(). Also note that vfork on GNU/Linux stops the parent until it exit by either calling _exit() or executing execve(). Normally (in older systems) it was used solely to execute another program. BTW. On linux, If you do execute a program right away, vfork is not really better than fork. On older systems (e.g. DG/UX) fork copied the whole memory before continuing, and vfork changed the shared (read: parent) memory. On linux fork use copy on write so it does not copy (almost) any memory before doing its work.

I understand your need for vfork. Just be careful. In point of fact, I do not need vfork at all. It can be eliminated from the system calls list altogether, as far as I'm concerned. Unfortunately, it is GNU make that uses vfork in order to start new processes. The reason I care what make does is a project of mine called fakeroot-ng [1]. It attempts to achieve the same broad effect as fakeroot[2], except using the more thorough PTRACE technology, rather than LD_PRELOAD like fakeroot. As such, it hooks itself between the run time library and the kernel (as opposed to between the program and the runtime library, which is what fakeroot does). The problems there tend to be somewhat unique, due to glibc's close intimate relationship with the kernel. In particular, I am trying to tackle the problem of how to remain attached as a debugger to a process that spawns a new child process (threads are a subject I have not even begun working on). Copying ideas liberally from strace (it's insane to try and copy code from there - the code there is a total mess), I tried turning calls to fork into calls to clone, adding the CLONE_TRACE and removing the CLONE_UNTRACE flags. This works for program that call clone or fork, but when the program calls vfork, it segfaults after it returns from the syscall. Of course, in order to debug that properly, it is best to construct a sample program that does vfork and little else. Of course, if that program then crashes even without fakeroot-ng, then I've got a program. This is what the sample program I sent to the list was all about. Thank you all for your help. All this is made worse when you consider that, since fakeroot-ng is already a debugger for the process that segfaults, gdb cannot connect to it. Anyways, I think I have a fairly good idea on what the source of the problem might be now, and I'm hoping to get this resolved soonish. One comment - If the parent failed when you returned from call in the child, It is proof that at least the stack memory was common to both. sys_vfork calls do_fork with CLONE_VFORK|CLONE_VM. The first means return to parent only after child releases the VM (i.e. - calls exit or execve), while the second means to have the two share the same VM. As such, yeah, the stack is commune when calling vfork. Of course, this means that the function vfork as implemented in glibc needs to do some magic in order to not trash the stack when it returns. I believe it is this magic that causes the segfault. Still looking into it.

Hi all,
Here is fork.c in its entirety:
#define _GNU_SOURCE
#include sys/types.h
#include unistd.h
#include sched.h
#include sys/syscall.h
#include signal.h
#include stdio.h
int main()
{
pid_t child;
printf(Started, pid=%d\n, getpid() );
//child=fork();
child=vfork();
//child=syscall(__NR_fork);
//child=syscall(__NR_vfork);
//child=syscall(__NR_clone, CLONE_VFORK|SIGCHLD, 0);
if( child0 ) {
perror(fork failed);
return 1;
}
if( child==0 ) {
printf(Child, pid=%d\n, getpid() );
} else {
printf(Parent, child=%d\n, child );
int status;
wait(status);
}
return 0;
}
I compile it with gcc 4.3.2 from Debian Lenny with the following command
line:
gcc -O0 -g -o fork fork.c
When I run it, I get:
$ ./fork
Started, pid=13711
Child, pid=13712
Parent, child=13712
Segmentation fault
The core dump is of no use whats o' ever - it shows an rip of 0. If the
program is run from within strace, there is no segmentation fault. Same
goes if it is being run by gdb or valgrind. In fact, I'm having a
somewhat difficult time deciding whether it is the parent or the child
that dumps core! (adding a printf after the wait confirms that the
child returned with status code 0, so it must be the parent that is seg
faulting).

Compiling your program with -Wall emits the following warning on Debian
Squeeze (amd64, gcc 4.3.3):
fork.c: In function ‘main’:
fork.c:34: warning: implicit declaration of function ‘wait’
This may indicate a headers mismatch in Debian.
Running the program gives the same result as yours.
Hope this helps.

The last time It happened, I did not get redirected and I had to call the support team to find out what is going on.

Re: OT: Help with simple Linux maintenance
Hi If it is working from the terminal command after command, it seems that the script is not waiting for the completion (meaning waiting till all the side effects are done) of one command before it starts the next. It seems that the easy way to test it, is to put a large sleep between every 2 commands (I am sure that there is a more elegant way to solve this, but I don't know it) Shahar - Original Message - From: Dotan Cohen To: Gal Goldschmidt Cc: linux-il Sent: Monday, June 15, 2009 12:30 AM Subject: Re: OT: Help with simple Linux maintenance A friend of mine is looking for basic Linux support at the Safed area.
