Open Source Distributed Shell Tools? 31

ColonelForbin74 asks: "While some may assume that most larger server clusters run advanced / custom software(i.e. Beowulf, cfengine, OSCAR), many of those stuck in the not-research-this-site-runs-production world know this simply isn't the case. Many people like myself are working with medium-to-large scale clusters with little help other than shell for() loops and some SSH trusted keys. What application-level tools are out there that might help SysAdmin / AppSupport types like myself run commands across a given cluster, push files out, etc? In my desperation to have some sort of tool in my toolbox, I've actually created one. However, I have a hard time believing this is the best thing out there, and would appreciate all the ideas and links I can get!"

Convergence of Biology and Computers? 388

Pankaj Arora asks: "This summer I am working on both Bioinformatics and Molecular Biology research projects at the Mayo Clinic Rochester. Being an MIS major with a heavy CS background, I've been learning about biochemistry performing polymerase chain reactions (PCRs) and RNA retranslation among other things. I've learned biology works a lot like computers; binary has 1s and 0s, DNA has nucleotides: A, T, C, and G. Binary has 8 bits to a byte, DNA has 3 nucleotides to a codon. Computers and biology seem to have a natural fit; information is encoded and represented 'digitally' in a sense. I was wondering what people thought about the future of biology-based and genetics-based computing due to the immense efficiencies that lie in nature. This has been discussed to an extent here, but there were some specific aspects that I feel are quite important and were not discussed thoroughly, thus I have a few questions to pose to the Slashdot community."

What Jazz Records Would You Reccommend? 235

zmotula asks: "What Jazz records do you think are a must-have for a Jazz Geek? I've got about twenty records I really love (Kind of Blue by Miles Davis, Tijuana Moods by Charlie Mingus, Lush Life by John Coltrane, just to mention some) and I want to spend some more money on buying more. Alas, I can only afford buying around two CDs a month. What records do you think are essential?"

Organizing and Analyzing Mounds of Research Text? 28

Andrew Green asks: "Four years ago, I stopped working on my Master's thesis in Social Anthropology. Now, I'm getting back to it again, and I find there's a _lot_ of text to deal with. I have a 350-page field diary, a dozen transcripts of recorded interviews, lists of books and articles, extensive notes about the books and articles, and the books and articles themselves in dead-tree or electronic format. I want to organize _all_ of it. I need to keep track of all the different text files on my computer (most are in MS formats, though I now use GNU/Linux), which ideally means keeping personalized sets of metadata about each file, linking files to other files and to entries in bibliography lists, and having some sort of version control. I'd also like to be able to do a free-text search on all texts on my local hard drive. And, most important of all, I need to build a hierarchical list of topics that are relevant to my thesis and relate specific sections of all these texts (not just whole files) to different topics. Any ideas? I know there are proprietary solutions out there, but I don't want to use them. What free applications can best deal with some or all of my needs? Would I be better off building something myself?"

12/7 and Overtime on a Salary? 932

over-timeout! asks: A company I work for (in the U.S.A.) had submitted a statement of work to a client, who waited for a month before signing the work order. The work order explicitly stated a timeline which would start from the time the order is signed. However, the client is insisting on the project being completed by a fixed date, as discussed with our company's management, instead of the deadline that starts from the signing of the work order. Although our company representatives tried to push back on the date, the client refused. Because the client is among our company's biggest customers, our company's management caved in and agreed to their deadlines. Management has told us meeting deadlines means that for the next month to six weeks all of the developers involved will have to work 12 hours a day, 7 days a week. The contractors involved are going to get compensated by being paid by the hour. But us salaried employees are going to get nothing in return for trading in what's left of our life so someone else in the company above us can make money. Obviously this isn't fair, but what are the alternatives in this down economy, where jobs are hard to find?" A related articles on this subject discusses suing for overtime, and California residents should find this companion article pertinent, as well. What can you do when management agrees to a timeline and a workload that may make your job, as a programmer, difficult-to-impossible?

Storing Pictures While Backpack Travelling? 134

Amgine007 asks: "A friend of mine will be leaving in January 2004 for a 12-to-18-month 'around the world' trip. He's pretty technically saavy, but not really much of a computer-and-gadgets geek. He has an interesting problem: How do you live out of a backpack for a year (or more) and manage to take and save a lot of digital pictures (say 10,000), if you will have very few connections to the outside world -- few sources of power (at the odd hostel or train station outlet), no internet, and no USB?"

On the State of Today's eBook Readers? 24

ashkar asks: "With the constantly expanding selection of eBooks available today, I have been wishing for a dedicated reader more and more. Novels, computer reference books, man pages, and more could be readily available, but after searching around, I've realized that the market hasn't progressed much in the last few years. The popular readers either use proprietary formats or are too bulky. An ideal would be able to read HTML, PDF, ASCII, and any other eBook formats widely used. I have thought about getting a PDA, but I don't need the extra features they provide at a higher cost. Has anybody found a good solution to this, and if not, are there any companies out there working on providing such a solution?" AS PCs become smaller, and assuming eBook readers don't mature and become popular in their own right, how long will it be before we see the PC (in it's portable form) as the primary "e-reading" device?

Creating an Open Alternative to Bugtraq? 25

mbogosian asks: "I am not a sysadmin, nor am I a security expert, but I appreciate those who are. In response to a recent story, I went out and registered two domain names: opentraq.org and opentraq.net. I am hereby throwing down the gauntlet: I am willing to have them resolve to DNS servers belonging to a group of volunteers who wish to start and maintain an Open alternative to security services like BugTraq and others offered at the SecurityFocus website without being encumbered by the OIS Security Vulnerability Reporting And Response Process. I will continue to pay the renewal fees for the names as long as someone wants to continue the the effort. After the project becomes established and is maintained by a reputable (i.e., non-commercial) group of volunteers, I am willing transfer ownership of the domains to that group at no cost. Feel free to contact me if you are interested. Let the discussion begin! " Do you feel such a thing is necessary at this time? Why or why not?

Supportive Courses for Bioinformatics? 37

Per Christian Henden asks: "I`m aiming for a masters degree in bioinformatics, and I`m uncertain which courses would be good to follow (and my counselor doesn't know, either). There are of course some courses that 'belong' to this degree, and I`ll take those, but I get to choose a number of additional courses. I want to ask people working in bioinformatics 'What (CS) subjects are important or especially useful in bioinformatics?' I`m planning on choosing 'Large Datasets', 'Parallel Programming', 'Image Classification', and 'Subsymbolic AI', because I think those are important, but I`m really not sure what is useful or not in real life bioinformatics." Other Ask Slashdot articles, which have touched on bioinformatics, have dealt with magazines, books and graduate schools.
The Internet

Websites of Knowledge? 105

AvantLegion asks: "Every now and then, I stumble upon a website that is just a veritable tome of knowledge - be it of a certain theme (like Snopes.com) or more general information (Everything2.com). Free documentation databases are invaluable, but rarely seem to come up very early in Google searches. What websites out there do you consider to be indispensable sources of knowledge? (save the obvious Slashdot jokes). Where do you look up information besides combing through search engine results?"

Ageism in IT? 861

Embedded Geek writes "It's hardly a new topic, but BBC is running a story about ageism hitting Gen-X, especially in IT. As a 34 year old coder, I was horrified to hear a quote from a *hiring manager*: 'In the IT sector (and coding in particular) younger minds generally work faster -- I would rather employ a keen teenager who code programs computers quickly than an older person.' It didn't help that the person is 32 years old. My kneejerk reaction, the same one anyone else over 30 would have, is that the guy is a buffoon (I'll withhold my preferred, spectacularly vulgar, term). The problem is that I do not believe his idiocy is unique - I have definitely felt the vibe when interviewing. It's frustrating, since Gen-X is finally shedding the media hyped 'slacker' stereotype only to run headlong into this garbage. Have any other Slashdot readers seen this? What is the youngest you can be before some PHB declares you fit for the scrap-heap? Other than stocking up on hair dye and botox, what steps can I take to prepare for the future? Share your war stories here." Ask Slashdot handled this topic over two years ago. Of course, this behavior could be explained away as economic concerns, as the decision to hire younger (and typically cheaper) employees can directly affect the bottom line. However, one has to wonder if the decision to go with less experienced programmers also affects software quality, in the long run. What are your thoughts on this subject?
Java

J2EE vs. .NET in Productivity Comparison? 68

Matt Hughes asks: "When does one programmer's preferences (Java over Microsoft-anything because they hate Microsoft, or Microsoft over open-source because open-source is evil) and the variety of choices start to erode productivity? As a J2EE developer for the past few years, I admit that I've become frustrated at the number of choices out there. Every one offers a different way of doing things but they don't all interoperate (JBuilder doesn't natively understand Struts) and none of them -- in my experience -- pulls all of the web technologies together very succinctly. Does Visual Studio .NET and the .NET framework pull this together better than the open-source projects out there, or is it just as complicated in your experience? Is .NET too immature to be trusted? What are your thoughts?" For those interested in the raw performance numbers, Slashdot did a performance comparison between the two technologies, in an earlier article.

Open Source Linux Based POS Systems? 45

tha_mink asks: "I am currently working for a number of clients that have very similar needs for a cost-effective POS system that may be integrated online. (read : cheap if not free) These are all small business clients with small budgets and so I would like to suggest something Linux-based, with a nice GUI, and a database I can get at through the web (PostgreSQL would be great). I have searched for and read the past Slashdot articles on the subject only to find that they are old and out of date. I have also done numerous google searches only to find that there is not a clear leader. My clients don't really need things like payroll and purchasing but inventory control, accounting, and customer storage are important. So I ask: What systems are available to fulfill the needs of small business without breaking the bank and without requiring any software from Redmond?"

Stories of Open Source Failures? 99

ahodgkinson asks: "We often hear about companies, government agencies, schools and other organizations that migrate from Microsoft to open source based systems. We sometimes hear about organizations that evaluate Open Source and then elect to remain with their existing proprietary system. Both of these events represent represent a 'non-failure' for the open source movement. I'm interested in knowing more about the Open Source 'failure' events, namely when organizations move away from open source to a proprietary solution. Does anyone know of organizations that have moved from an Open Source based IT solution (back) to a proprietary system? Or where such a move was contemplated but not made? I'm specifically interested in larger organizations that have 'undone' a strategic move to Open Source, and their reasons why. Given your examples, is there anything we can learn from them?"
