CurtMonash writes "MapReduce sits at the heart of Google's data processing — and Yahoo's, Facebook's and LinkedIn's as well. But it's been highly controversial, due to an apparent conflict with standard data warehousing common sense. Now two data warehouse DBMS vendors, Greenplum and Aster Data, have announced the integration of MapReduce into their SQL database managers. I think MapReduce could give a major boost to high-end analytics, specifically to applications in three areas: 1) Text tokenization, indexing, and search; 2) Creation of other kinds of data structures (e.g., graphs); and 3) Data mining and machine learning. (Data transformation may belong on that list as well.) All these areas could yield better results if there were better performance, and MapReduce offers the possibility of major processing speed-ups."
An anonymous reader brings news that the Software Freedom Law Center has published a guide for compliance with the GNU General Public License. The purpose of the guide is to prevent "common mistakes" the SFLC has encountered during its various GPL violation investigations. Their suggestions include close scrutiny of software acquisitions, more precise tracking of changes and updates, and avoiding "build gurus." They also provide tips for dealing with a violation. The full guide is available at the SFLC's website.
Snydeq writes "Fatal Exception's Neil McAllister questions the wisdom of standardizing on a single language in the wake of the ECMA Committee's decision to abandon ECMAScript 4 in favor of the much less ambitious ECMAScript 3.1, stunting the future of JavaScript. Had the work continued, McAllister argues, it could have ushered in an era of large-scale application development that would ensure the browser's ability to meet our evolving needs in the years ahead. 'The more I hear about the ongoing efforts to revise the leading Web standards, the less convinced I am that we're approaching Web-based applications the right way,' McAllister writes. 'If anything, the more we talk about building large-scale Web applications, the more we should recognize that a single style of programming will never suit every job.' McAllister's simple truth: JavaScript will never be good for everything — especially as the Web continues to evolve beyond its original vision. His solution? 'Rather than shoehorning more and more functionality into the browser itself, maybe it's time we separated the UI from the underlying client-side logic. Let the browser handle the View. Let the Controller exist somewhere else, independent of the presentation layer.'"
Anti-Globalism recommends a posting up at O'Reilly's ONLamp on reasons that some companies are turning away from Perl. "[In one company] [m]anagement have started to refer to Perl-based systems as 'legacy' and to generally disparage it. This attitude has seeped through to non-technical business users who have started to worry if developers mention a system that is written in Perl. Business users, of course, don't want nasty old, broken Perl code. They want the shiny new technologies. I don't deny at all that this company (like many others) has a large amount of badly written and hard-to-maintain Perl code. But I maintain that this isn't directly due to the code being written in Perl. Its because the Perl code has developed piecemeal over the last ten or so years in an environment where there was no design authority.. Many of these systems date back to this company's first steps onto the Internet and were made by separate departments who had no interaction with each other. Its not really a surprise that the systems don't interact well and a lot of the code is hard to maintain."

This was confirmed this morning when Gizmodo published (leaked)specifications for the Inspiron 910." I hope that's not the final form of the keyboard, though -- lots of wasted space on each side.
Ruphus13 writes "As the mobile space heats up, Sun has released the source code for Java Lightweight UI Toolkit under the GPL v2 license. ZDNet quotes Sun's senior director of embedded software saying, 'By creating LWUIT, Sun is reaffirming its commitment to the mobile development community and by open-sourcing the LWUIT code, we are enabling mobile developers to quickly and easily create rich, portable interfaces for their applications -- functionality that they have been requesting for some time.' Will Adobe follow suit?" Sun is also working on some fixes to holes in their mobile Java platform, which were discovered by a Polish researcher who demanded €20,000 to disclose the information.
Mikeselectricstuff writes "HP's 20b business consultant calculator isn't the sort of thing that would normally interest the average Slashdotter, but HP has released a Devkit for it, including schematics and source for a sample application, and they appear to be actively encouraging people to re-purpose it. Maybe the engineers thought a business calculator was just too boring for their hardware? The calculator is based on an Atmel ARM chip, and it has a bootloader and JTAG interface to allow user applications to be written and downloaded, turning a boring calculator into anything you can do within the constraints of the hardware."
Linux Foundation Paving Way for New Kernel Developers
Jack Spine writes "The Linux Foundation has published a how-to document for developers who want to negotiate the hidden shoals of open source. According to both the Linux Foundation and the Open Source Consortium, developers can get frustrated with the processes in open source coding, especially for enterprise-class projects like Linux. 'A guide to the kernel development process' aims to encourage participation from new programmers by explaining what's involved. Some developers and businesses attempting to submit changes to the Linux kernel find themselves tangled up with the processes used, according to the guide, which was written by Jonathan Corbet, executive editor of lwn.net and himself a Linux developer."
Da Massive writes with this excerpt from ComputerWorld: "For a technology that has been in stable release since May 22, 2000, PHP 4 has finally reached the end of its official life. With the release of PHP 4.4.9, official support has ended and the final security patch for the platform issued. ...With eight years of legacy code out there, it is likely that there are going to be a fairly large number of systems that will not migrate to PHP 5 in the near future, and a reasonable proportion of those that will not make the migration at all. For those who are not able to migrate their systems to the new version of PHP, noted PHP security expert Stefan Esser will continue to provide third party security patching for the PHP 4 line through his Suhosin product."
Open Source Helps New IT Grads Get Foot in the Door
Yes, some US IT jobs are disappearing, but Linux.com (which shares a corporate overlord with Slashdot) has a recent story emphasizing the job advantage that involvement in open source projects can give young programmers who aren't planning to ditch their dreams of making a living in the field. The article focuses on one programmer's experience with Google's Summer of Code, which led directly to her job working on the Drupal content-management system. But the underlying message (that involvement in open source projects provides a background of experience otherwise difficult to obtain because of the chicken-and-egg problem of "experience required" job opportunities) is generalizable to many other forms of open-source involvement. Do you have a job that you landed because of your unpaid open-source programming?
Tracking Near-Earth Meteors With a 1.1 Petabyte Database
Lucas123 writes "The latest and most ambitious attempt to detect 'near-Earth objects' (NEOs) is the Panoramic Survey Telescope and Rapid Response System, or Pan-STARRS. When it's fully operational several years from now, it will have four telescopes, each with a 1.4-gigapixel camera. The system is expected to be able to track virtually all NEOs larger than 300 meters in diameter as well as many smaller ones. Rather than turning to an expensive supercomputer equipped with hundreds or thousands of processors, Pan-STARRS will use a cluster of 50 PC servers connected to 1.1 petabytes of disk storage via fast Infiniband networking gear."
Snydeq writes "Sure 'legacy systems archaeologist' ranks as one of the 7 dirtiest jobs in IT, but COBOL skills might see a scant revival in the wake of California's high-profile pay-cut debacle. After all, as Fatal Exception's Neil McAllister points out, new code may in fact be more expensive than old code. According to an IDC survey, code complexity is on the rise. And it's not the applications that are growing more complex, but the technologies themselves. 'Multicore processing, SOA, and Web 2.0 all contribute to rising software development costs,' which include $5 million to $22 million spent on fixing defects per company per year. Do the math, and California's proposed $177 million nine-year modernization project cost will double, McAllister writes. Perhaps numbers like those won't deter modernization efforts, but the estimated 90,000 coders still versed in COBOL may find themselves in high demand teaching new dogs old tricks."
Beezzie writes "Last week, California Governor Arnold Schwarzenegger ordered a pay cut, to minimum wage of $6.55/hr,, for 200,000 state workers because a state budget hadn't been approved yet. The state controller, who has opposed the pay cut on principle and legal grounds, now says the pay cut isn't even feasible because the state's payroll systems are so antiquated. He says it would take 6 months to go to minimum wage, and 9 months more to restore salaries once a budget is passed. The system is based on COBOL, according to the Sacramento Bee, and the state hasn't yet found the funds or resources, in 10 years of trying, to upgrade it." The article quotes a consultant on how hard it is to find COBOL programmers; he says you usually have to draw them out of retirement. Problem is, if there were any such folks on the employment rolls in California, Gov. Schwarzenegger fired them all last week, too.
Alxtoth writes "Snowflake is a new BSD-licensed tool that parses SQL Select statements and generates a diagram. It shows parts of the underlying SQL directly in the diagram. For example: x=30, GROUP BY (year), SUM (sales), HAVING MIN (age) > 18. The primary reason for the tool was to avoid Cartesian joins and loops in SQL written by hand, with many joined tables. The database will execute such a statement, if syntactically correct, resulting in runaway queries that can bring the database down. If you sit close to the DBAs, you can hear them screaming... "
