Dell Ships Ubuntu 9.04 Systems Ahead of Windows 7 Launch
Dell’s U.S. website has started offering Ubuntu 9.04 on a Mini 10V and Inspiron 15N laptop. The move comes less than two months before Microsoft’s Windows 7 launch — essentially reinforcing Dell’s commitment to Ubuntu. But will Dell pre-load Ubuntu 9.04 on a desktop PC? Here’s some analysis.
Save time on downloads with delta RPMs in Fedora 11
Fedora 11 introduced a great new feature: delta RPM updates. This feature creates delta RPM packages (.drpm) that are binary “patches” to the existing RPM packages. Instead of downloading all files, regardless of whether they have changed or not, a delta RPM will only download the files that have changed compared to the previous RPM package. Once the delta RPM is downloaded by the Presto plugin for yum, it will try to reconstruct a full RPM based on the contents of the previous RPM, plus the newly changed files from the delta RPM. The newly-created RPM will then be installed by yum.
Install 32-Bit Support Into 64-bit Fedora
If you’re running newer hardware, there are some definite advantages to installing a 64-bit operating system. But, if you still need to run any 32-bit applications, you’ll need to have the 32-bit support libraries installed. Different Linux distros handle this in different ways.

Red Hat Enterprise Linux (RHEL) 5.4, which was made available to subscribers on Wednesday, incorporates a kernel-based virtual machine (KVM) hypervisor--software that allows multiple virtual operating systems to run on a host machine or system. The company first announced its move to KVM from its previous Xen-based hypervisor strategy in June 2008, with RHEL 5.4 promised as the first production OS so equipped in February 2009.

OS chameleons: 4 'transformation packs' turn one OS into a knock-off of another
Do you want to try Windows 7 but don't want to shell out the upgrade price? Or do you long to give Mac OS X a test run but don't particularly want to buy a Mac? There's a way to do that (although the OS vendors won't love you for it): Use a "transformation pack." These software packages go beyond changing the graphical user interface to make it resemble that of a different OS. Most of the technically sophisticated transformation packs will tweak or patch the native operating system's code and add startup applications to more accurately simulate the functionality of another OS.

EU fears Oracle will kill MySQL, but is that even possible?
Oracle's pending acquisition of Sun has hit a snag. The European Commission is concerned that Oracle's will terminate the open source MySQL project, a move that would have a detrimental impact on competition in the database market.

The world's oldest working computer
It doesn't run Linux, in fact it uses 900 Dekatron gas-filled tubes each capable of holding just a single digit in memory, using paper tape for both input and program storage. But The National Museum of Computing in England is restoring it and offering geeks the chance to own a share in the project. Which is kind of cool.
GCC vs. LLVM-GCC Benchmarks
Last Friday we published Mac OS X 10.6 benchmarks and then on Monday they were joined by Ubuntu 9.10 vs. Mac OS X 10.6 benchmarks. One of the requests that has come up since publishing those articles are to carry out a set of tests comparing the performance of LLVM and LLVM-GCC. With Apple's Snow Leopard release, some parts of the operating system were built using LLVM-GCC for optimized performance, although this compiler is not yet matured. In this article we have a set of 12 benchmarks comparing GCC to LLVM-GCC.
