Re: Server Disk Problem
Hi folks! Here we go: In addition to posting this query, I found and downloaded a short LVM Howto. In addition, I used a live openSUSE 11.3 CD. Following the Howto, I was able to discern that: 1. The server had two LVM volumes on two separate physical drives configured for RAID 1. 2. They showed as /dev/sda and /dev/sdb. 3. After going through the Howto instructions, I was able to demonstrate that sda was corrupted and unmountable as an LVM drive but sdb was OK, and I was able to get into it and copy data to a disk on key. If anyone is interested, I will prepare a log of the procedure and post it. At this point I am using the LVM instructions as a bit of a parrot, but that looks likely to change for the better. :) Thanks for your response, Daniel P.S. If anyone is wondering, why openSUSE and not ...?, please note that I have been a SUSE user since 1999 and I'm too lazy to change. In any event, 11.3 seems to be a good release.

I am trying to assist in the following situation: The user has a 1u IBM Pizza server. It was configured as one partition (ext3) and loaded with Centos something-or-other, with the partition set up as a single LVM volume (yes, including the root directory). One fine day, after a reboot, it ran fsck which conked out after checking about 12% of the disk advising to run fsck manually. At that point, we logged in as root, and ran fsck -n /dev/whatever to see what's happening. The latter yielded the dreaded corrupt super block, try the next one (8193). That (as I kind of expected) didn't work either. From being root I can see the various directories an even cd to them. I am aware that it means little if their contents are corrupted. Question: 1. Are there any recovery tools for this kind of situation? 2. Is my only choice, to install another pre-partitioned hard disk, log in with (say) a live CD, mount the corrupt disk and try to manually copy my data directories?

Re: Alternative for getline() function in AIX 5.3

This is called something around Utilities for Linux or some other lie. So you do not need to force gcc to compile under AIX, but only use it. Same goes, probably, for many additional libraries. I didn't check, but it is quite likely that while they supply gcc and many other GNU utilities, they do not have glibc. While glibc's getline() is trivial to port to AIX, much of glibc is very closely related to the kernel's APIs, so it varies a lot from kernel to kernel. Last time I checked, glibc was only available for Linux. But needless to say, parts of glibc (like the aforementioned geline()) should have no trouble to compile on AIX. -- Nadav Har'El| Wednesday, Jul 28 2010, 17 Av 5770 n...@math.technion.ac.il |- Phone +972-523-790466, ICQ 13349191 |Does replacing myself with a shell-script http://nadav.harel.org.il |make me impressive or insignificant? ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
Re: Playing TAU lectures from videos.tau.ac.il

What this thread asks is not how to redistribute these films for free or for pay [FreeDist], but rather how to legitimately view them on Linux while fully respecting the copyrights. Apparently, the TAU workers did not do enough work to ensure portability and interoperability for non-Microsoft-based operating systems, and the people who asked here want to find a good workaround. This thread is entirely due to their lack of ability (or because they did not care enough), and it should be expected given that people use Linux and want to view the lectures there, which is within their rights as TAU students. Agreed. That may not be a bad thing, because it gives publicity to the university, and allows other people to enjoy your content. See: * http://remix.lessig.org/ * http://ocw.mit.edu/ (OpenCourseWare). Yes, but TAUs policy on copyright is not on discussion, nor am I authorized to change it. These internal means likely take time, as many people who have tried to contact the operators of web-sites that do not function in non-MSIE-browsers can attest to. In the meanwhile, people would need some Linux-specific workarounds, which would not be needed if the TAU staff cared enough about checking that. You reap what you sow. I do not like prejudice. The only way to fix TAU issues is via the help desk. Trust me, we're not your usual Joe ISP. We are a strong Unix/Linux shop, and most of our applications, especially web apps, are based on open source. But it has been explained to you that Linux users have already addressed the help desk, which has not found (or which doesn't really care to find) a way to solve the problem, thus leaving Linux users unable to access the pages that they need for their course work. What does trust me mean in such a case? Hiding behind copyright law is a weak excuse. The university cannot arrange its student pages in such a way that proprietary software is needed for access, and then complain when students who are told to use the pages try to access without the proprietary software. I don't think that argument is populistic, as you have argued; I don't think you do either, if you will think about it. -- Ariel -- Ariel Biener e-mail: ar...@post.tau.ac.il PGP: http://www.tau.ac.il/~ariel/pgp.html ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il -- Stan Goodman Qiryat Tiv'on Israel ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
Looking for a programmer for a web project - Speedy Composer
Hi all, I hope it's OK to write to this list. I'm looking for a programmer for an open source web project called Speedy Composer - a program that will automatically compose music. This is a project I did a few years ago, which can compose melodies using MATLAB - using artificial neural networks. I need a programmer who can convert this MATLAB code into web interface, allowing users to create accounts, then compose their own melodies according to specific musical chords, and saving the composed melodies in MIDI format to the user's account on the server, letting the users play the music or download it in MIDI format. The programming language is open, can be PHP and/or C/C++ or Java, or any other open programming language. I want to create a website using this program (with English interface), and also release it as an open source project. You can find more details and examples of melodies composed by this project on this website: http://www.speedy.net/composer/ There is also a project on SourceForge, where you can download the MATLAB source files project files: https://sourceforge.net/projects/speedycomposer/ There are two options of working with me: 1. Partnership. We can share the profits from this project. Let me know if you are willing to work as a partner. 2. Freelancer. If you want to work as a freelancer, let me know how much you will charge per this project, or per hour and how many hours are estimated. If you are interested, please send me a short resume and programming skills, how many hours you estimate to complete this work, whether you prefer partnership or freelancer, and how much you will charge (including all taxes). Please send all this information to my e-mail (u...@speedy.net), and don't forget to write Programmer - Speedy Composer as the title. Also, if you have advice on ways to find a programmer (where to advertise), please let me know.

OT: web fonts
Not a Linux question, but probably relevant for some people here. I'm working on a Hebrew website [1] and although it looks great in Firefox, Opera and Chrome on Linux, IE on Windows diplays terrible, terrible fonts. Which fonts should I specify in the CSS, ones that I can trust look decent and are installed on default Windows installations? I could probably just look at the code for Walla or TheMarker, but I figure that I would get a better answer here. Thanks.

Re: OT: web fonts
I would suggest not to mess with fonts, as for most usages it already has good choices for every operating system and browser. You can instead specify font-family:sans-serif, as serif fonts are never looking good on screens (but ideal for prints). If you are very geeky, you can load fonts fronts from the stylesheet itself, so you can show culmus fonts for Windows, as well as any other chosen font.
