Debian Project Pleased with Ten Times Faster Build Server
Thursday, March 18, 2010 @ 02:21:39 CET by tw45admin (53 reads) |  New in Debian's infrastructure is the SC846 server with a 4-unit height and two Intel Xeon E5540 processors. While the previous five-year-old system took 20 hours for a build, the new one took less than two hours, according to the project and its benefactor, Thomas Krenn AG, in a joint press release. A build speed factor of ten? "The people at Thomas Krenn were just as excited as we were," Alexander Reichle-Schmehl of the Debian press team revealed to Linux Magazine Online. Debian project lead Steve McIntyre went further: "To get the best possible out of the new system, I ran a series of benchmarks with various configurations: various RAID levels, various filesystems and so on. The figures that emerged were truly astounding."

Search Patterns: Design for Discovery
Wednesday, March 17, 2010 @ 16:24:02 CET by tw45admin (52 reads) |  Whether you think "search" is sexy or not, you probably can't live without it. In fact, according to the blurb on the book's back cover, "It (search) influences what we buy and where we go. It shapes how we learn and what we believe." That's a powerful statement, and probably more true than we realize (or we wish). While most of us experience search as users, Morville and Callender provide a practical guide that allows you to build your own search applications...but how good of a guide is it? I decided to find out (hence this review).

IO Profiling of Applications: MPI Apps
Wednesday, March 17, 2010 @ 15:03:41 CET by tw45admin (49 reads) | Strace is one of the those all-purpose tools that can be used for debugging problems on your system(s). It can also be used for digging into the IO profile of applications - even if you don’t have the source code (but with Linux you should always have access to the source). In the last article it was shown how strace can be used to gather a great deal of information about the IO behavior of applications. The reason that strace can be useful is because IO is performed using libraries on Linux (for the vast majority of applications). Because of this strace can record the information of the specific system call (syscall) in a form that is very useful.

NVIDIA Drivers Fan Speed Alert for Ubuntu 10.04
Wednesday, March 17, 2010 @ 13:54:07 CET by tw45admin (71 reads) |  On the Ubuntu developer mailing list, Alberto Milone warns testers of the alpha version of Ubuntu 10.04 about problems with the resident NVIDIA driver versions 195.36.08 and 195.36.03. The 195.36.08 and 195.36.0 driver versions can possibly affect the GPU fan speed, according to Milone. The original alert came from NVIDIA forums themselves and referred to Windows driver version 196.75. After NVIDIA detected the fan speed problem, it removed the driver and published an alert on the drivers download page.Milone himself had not experienced any problems with the drivers, but suggested to remove them to be on the safe side. His mailing list entry indicates how to deactive the drivers and use the open NVIDIA driver instead for the time being.
The complete text of this alert is at Ubuntu User Magazine.

Novell Mono project bringing Silverlight to Apple iPhone
Wednesday, March 17, 2010 @ 12:47:21 CET by tw45admin (69 reads) |  MonoDroid, which will enable deployment of .Net-based applications on Google Android phones, is in development at Novell, with a preview release planned for August, the head of the project said. The runtime project is part of Novell's Mono effort, which has been responsbile for putting Microsoft .Net-based technologies on Linux and other non-Microsoft platforms. "[MonoDroid is] Mono running on the Android, but it's also all the APIs so you can talk to the Android APIs," said Miguel de Icaza, vice president of the developer platform at Novell and leader of Mono, in an interview at the Mix10 conference.

Mastering Redirection in BASH on Linux
Wednesday, March 17, 2010 @ 12:45:14 CET by tw45admin (71 reads) | It took me ages to learn bash redirection properly, and I still have to concentrate sometimes to keep my &s and my >s straight. Here's the lowdown in case you, too, have intermittent brain failure on this one. Bash has three standard file descriptors: stdin, stdout and stderr, which refer respectively to input, output and error output. By default, all of these are directed to the terminal, so all input comes from the terminal, and all output (regular and error) will go to the terminal. You're probably already familiar with redirecting stdin and stdout...

Benchmarks: Mandriva, PCLinuxOS, Ubuntu, openSUSE
Wednesday, March 17, 2010 @ 12:43:13 CET by tw45admin (39 reads) |  Last week we delivered benchmarks of Fedora 13 Alpha and Ubuntu 10.04 (along with testing the Fedora 11 and 12 too), but today we have a new set of comparative benchmarks that are covering the latest development versions of Ubuntu 10.04, Mandriva 2010.1, PCLinuxOS 2010, and openSUSE 11.3. Here they are...As PCLinuxOS is only available in a 32-bit version, we had used the 32-bit version of all Linux distributions
tested in this article. This also led us to using an older system, which was a Lenovo ThinkPad T60. The ThinkPad T60 has an Intel Core T2400 processor clocked at 1.83GHz, 1GB of system memory, an 80GB Hitachi HTS541080G9SA00 SATA HDD, and an ATI Radeon Mobility X1400 graphics processor.

New Google Hire Takes Aim at Apple
Tuesday, March 16, 2010 @ 21:20:22 CET by tw45admin (60 reads) |  While Google Inc.'s budding rivalry with Apple Inc. has largely been a tight-lipped affair managed through legal and regulatory channels, one of the Internet giant's newest hires isn't being shy about airing grievances. Tim Bray, a software developer employed until recently at Sun Microsystems Inc., said Monday he has joined Google as a "developer advocate" with a focus on the company's Android operating system. And he wasted no time decrying Apple's vision of the cellphone market and strategy for the iPhone. "It's a sterile Disney-fied walled garden surrounded by sharp-toothed lawyers," Mr. Bray wrote on his personal Web site. "I hate it."

Get to Know MySQL Workbench
Tuesday, March 16, 2010 @ 19:12:45 CET by tw45admin (57 reads) |  If you are a database administrator or designer you know that the right tools can make your job remarkably easier. Now many dbas and dbds prefer the good ol' command line? After all, that's how MySQL was intended to be used, right? Right? Although MySQL works exceptionally well from the command line (it's not as hard as one would think), having a solid GUI tool just opens the user up to learning more powerful tasks and getting more work done faster. The one GUI tool that most people are accustomed to (with regards to MySQL) is the MySQL GUI Tools Bundle. It's a very user-friendly GUI that really does make the task of database creation/administration easy. But that tool is going away (read the full EOL announcement here). Upon first glance I thought the MySQL team had made a big mistake.
