Oh my gawd.. What do I do now?
by Ken Jones Sept. 7, 2007

Sept. 7, 2007

I have a single 120 Gig hard drive dual booted XP and Fedora Core 6 machine. Recently Linux had been running slowly. I restarted, selected the linux side and was shocked to have it fail into a fix disk mode. It suggested that I use fsck. I did and answered "yes" to seemingly thousands of questions. Once finally done fixing errors I rebooted. Now it fails completely. It complains about multiple "dma-intr: error" and {uncorrectable error} The last gasp before terminating says: "not syncing: Attempted to kill init!" Then it hangs indefinitely. No keyboard input has any affect. The XP side of the machine works fine, but it crashes overnight. Where do I start? What do I do? Can I save the linux half of the hard drive? Ken Jones

EEProm Programmer
by Tom Misilo Sept. 7, 2007

Sept. 7, 2007

Hey, I know this isn't completely linux related, but I was wondering if anyone happened to have any information on a Omni 64 EEPROM programmer.The Model is "Omni 64" And was manufactured by Oliver Advanced Engineering, Inc. (OAE). What I really want to do is be able to use the programmer to program some EEPROMs and make them boot eeproms for a few network cards so I can use LTSP (Thin Clients) on more computers I have and not have to attempt to boot from cd or floppy. Thanks, Tom Misilo -- Tom Misilo AIM:Tmisilo FL Jabber:tmisilo@jabber.org http://tmisilo.ath.cx

Awesome article about Windows v. Linux in the marketplace
by Eric Martin Aug. 17, 2007

Aug. 17, 2007

I found this on either digg or slashdot. It's a really good article and I agree with most of it. People won't even consider GNU/Linux while they can still get a copy of XP for free from a buddy. That's why I tell people that I won't support their pirating of software; and pitch FOSS at every turn to them. http://tlug.jp/articles/Windows_Is_Free Give it a read, it might spur some good conversations tonight.

Linux meta-questions - platform choice
by Adam Keck Aug. 10, 2007

Aug. 10, 2007

Hello All, I have some "meta-Linux" questions regarding platform choice. I am wondering if anyone knows of any research, papers, or other work that has been done on the topic. Given two major types of IT infrastructure: - Heterogeneous, where each application/service uses the platform to which it is best suited. - Homogeneous, where one bends a particular platform to fit every edge case. where the platform can be anything from and OS to a language to an application stack. o Under what general conditions is one infrastructure type more efficient than the other? o What other types of infrastructure are there? o More generally, how does one compare infrastructures in a rigorous manner? - How does one rigorously define "efficient" when comparing concepts like infrastructures? - What other metrics, besides "efficiency" (however defined) may be useful in comparing infrastructures? Does anyone know of any work where this topic has been abstracted and analyzed mathematically? Or of any trade papers where this question has been looked at in practice? So far, I found the following paper via Google: http://uic.edu/cba/cba-depts/ids/IDSNewsFiles/JGITM_Evaristopaper.pdf that seems to be on the topic and some hits on arxiv that appear related but not specifically on the topic. This relates to Linux in that convincing an organization to switch entirely over to Linux seems to be prohibitively hard in practice, but if one can show that the heterogeneous case above can be more efficient, then one can make the case for using Linux where it fits best. Thanks for any info/opinions/personal experiences! -Adam

core 2 duo extremely slow
by brad Aug. 3, 2007

Aug. 3, 2007

Hi All, I recently got in a nice new 2.4GHz core 2 duo with a bunch of memory, 8GB. I installed kubuntu i386 on it. To get use of the 8GB of memory i recompiled the kernel to enable high memory support, a.k.a PAE. When i booted the new kernel it saw all my memory, but it took 10-15 minutes to boot. i checked dmesg and it didn't seem to report anything out of the ordinary. Then, I thought that perhaps the 64bit version of kubuntu might be a better option. I installed kubuntu 64bit. The install took two days because every step was extremely slow. Once the install finished, i rebooted and it took 10-15 to boot. I was seeing the same symptoms of the 64bit install as i was with the 32bit install with PAE. I tried downloading the current kubuntu 64bit release as well as the beta of the next release. I'm also trying Fedora Core 7 64bit as i type, but that install is going just as slow. I hunted through the BIOS for any suspicious settings. I removed all the hardware except for the CD-ROM (to boot a live CD). I did searching through the interweb. All with no luck to solving this problem. If anyone has any suggestions, they will be much appreciated. keep cool, - brad

Programming position at UMass CS
by Hanna M. Wallach July 30, 2007

July 30, 2007

========================================== Software Engineer in Information Extraction and Synthesis Laboratory at UMass. Work with computer science researchers and other software engineers to revolutionize search over research literature and patents. See our preliminary web portal for computer science researchers at http://rexa.info/faq, and read relevant publications at http://www.cs.umass.edu/~mccallum/papers. Open source tools: Linux, Java, MySQL, Apache, ... Modern methods: Test-driven development using the Java/Spring framework. Feature-rich, Ajax-based web interfaces. Intellectually stimulating: Learn about cutting edge methods in machine learning, information extraction, web search, data mining, social network analysis. Serious hardware platforms: 100-CPU cluster, 10Tb disk, fast servers and desktops. Challenging work: Not cookie-cutter programming. Integrate with machine learning methods; program for high parallelism; devise algorithms for massive scalability. High creativity, intelligence, experience, and independent drive required. Experienced colleagues: Former VP R&D 170-person startup, extensive professional software engineering experience on the team. Tuition Benefits: Take UMass Amherst courses while working. Opportunities to publish research papers, if desired. True search: No internal candidate. Excellent follow-on prospects: Several others from the lab later got job offers from Google, Yahoo, IBM, Microsoft. (We want someone interested in staying multiple years, though.) Time off: Five weeks vacation and personal time, plus 13 holidays each year. Gorgeous location: Amherst, MA: bucolic surroundings plus active culture. Smith, Holyoke, Hampshire and Amherst Colleges all in the neighborhood. Office with window. ================================================ Rexa: http://rexa.info (create free login) Rexa is a digital library covering the computer science research literature and the people who create it. Rexa is a sibling to Google Scholar, CiteSeer and the ACM Portal. It's chief enhancement is that Rexa knows about more first-class, de-duplicated, cross-referenced object types: not only papers and their citation links, but also people, grants, topics---and in the near future universities, conferences, journals, research communities, and more. Rexa currently provides: * Keyword search on over 7 million papers (mostly in computer science) * Cross-linked pages for papers, authors, topics and NSF grants * Browsing by citations, authors, co-authors, cited authors, citing authors; (find who cites you most by clicking "Citing authors" on your home page) * Web-2.0-style "tagging" to bookmark papers * Automatically-gathered contact info and photos of author's faces * Analysis of research topics, their impact, and how they relate. Coming soon: * Much improved coverage of recent CS papers (it's somewhat weak now) * Ability to make corrections to extracted data Coming later: * Improved ranking, extraction and co-reference accuracy * Much more data mining * Broader coverage of more research fields Rather than seeing our siblings as competitors, we believe that such services are like "newspapers for the research community", and, just as it is tremendously important that there is not solely one national newspaper, we think there should be many such services. This is especially true since increasingly they will do more than simply supply raw information, but also provide subjective analysis, pattern discovery, and predictions. Rexa acts as driving application and showcase for our research in machine learning, natural language processing, information extraction, entity resolution, trend analysis and social network analysis. We aim to revolutionize the progress of science by providing new tools to help scientists do their job more effectively. ============================================ Official Job Posting: The Information Extraction and Synthesis Laboratory within the Center for Intelligent Information Retrieval (CIIR) at the University of Massachusetts Amherst is seeking computer professionals to support its expanding research.

Evolution plugin for MS Exchange
by chuck July 26, 2007

July 26, 2007

Hi All, I'm running kubuntu feisty with evolution 2.10.1. I'm trying to use the exchange plugin to connect to the MS 2003 Exchange Server at work. I have all the info about the implementation of Exchange from the IT folks, but I just can't make the plugin work. When I enter in my password, I get "Can not authenticate. (password incorrect?)" error. For the "Identity" - Username is my name (not surprising...) - Email address is my fully qualified email address. For the "Receiving email" - Server type is Microsoft exchange - Username is my domainname\username (Note: I've tried it without the domainname, still no joy). - OWA URL is the webmail URL (this has been confirmed by the IT folks) - Authenticate - I enter my password - seems to be ok. - Authentication Type - I've tried both secure and plaintext For "Receiving options" - Global Address List/Active directory settings - There's no entry I've looked at the Ubuntu launchpad website and there seems to be a few issues with the plugin. When evolution starts, it tries to search for mail folders, but finds nothing. I can't even terminate the process. I have to find out what pid number it is and terminate it with the 'kill <pid>' command. Has anyone managed to get this working? Is there some "magic" tweaking that I need to do? TIA, -Chuck

Any SQL-types out there? (more lab automation stuff)
by Stephen Daukas July 25, 2007

July 25, 2007

Good morning! In the continuing saga of automating various activities where I work, I have taken on processing data files. (Automating data upload is still somewhere in the air.)... This is rather simple in concept, but a bit less obvious in practice (aren't they all!): I would like to open up a CSV file and rearrange the columns according to a standardized order. Not every data file will have all of the standard columns (different probes collect different data), but column headers are standardized. So, I need to inspect each column header so that I can place it and its entire column of data into the proper position in the table, with empty columns inserted where needed to preserve the standard sequence of columns. In other words: A, D, C, G, H becomes A, [B], C, D, [E], [F], G, H where [ ] denote inserted empty columns There are literally hundreds of files of data in CSV format, and I intend to process each by itself, preserving the original, and creating a new "adjusted" file for the next step. (The next step would be to concatenate all files together for numeric processing.) Original files must be preserved (chain of custody requirements), so I am opening the file, selecting records using SQL, and am now ready to do the rearranging/writing to a new file... I didn't know if there is a "well known" SQL way of doing this (e.g., data manipulation statements of some sort), so I thought I'd see if any WLUGgers are also SQL-types. I have a few ideas for how to get this done, but they are "programmer-centric" algorithms, which tend to be different from "SQL-centric" algorithms... The reason for SQL is that I have to do this on a MS platform because that is the standard. But, if most of the real work is done in SQL, then I can easily move to another platform in the future and only have to change the "shell code". I am using VBscript as the "shell language" because it works with all MS apps and file system objects inclusive of CSV files. Thanks for any help!!! Best regards, Steve

Hard drive configuration
by Michael Long July 25, 2007

July 25, 2007

I hope someone can point me in the right direction. I have a SuSE 9.3 system that was fully configured when I bought it. When looking at fstab the drives are configured as follows: /dev/sdb3 / reiserfs acl,user_xattr 1 1 /dev/sdb1 /boot reiserfs acl,user_xattr 1 2 /dev/sda1 /raid reiserfs defaults 1 2 /dev/sdb2 swap swap pri=42 0 0 I downloaded OpenSuSE 10.2 and attempted to upgrade the system. When running either an upgrade or new install it tells me that /dev/sda3 is defined as /dev/sdb3 in fstab. Bottom line when I install opensuse 10.2 it sees my raid as sdb and the system is currently setup to have it as sda. I do not understand why my current configuration is the opposite of what a new install is finding. Where do I go from here?

I have no idea how many people might come. Maybe 30? Is someone taking RSVPs? If your main goal is to advance your knowledge in Linux you may find it more worth your while to attend a regular meeting then the BBQ. During regular meetings we cover specific topics or have free ranging discussions. My understanding is that the BBQ is more of a social event for the group.
