The world’s worst way to market Linux

At first, it sounds like a good idea. Nanchang, the capital of China’s eastern Jiangxi province, is requiring Internet cafe operators to replace pirated server software with legal copies of Red Flag Linux or Windows Server. What’s not to like? It’s estimated that China has an 82% software piracy rate. Getting businesses to go legal with a native Chinese Linux sounded like a win to me. Until, I saw the Red Flag Linux price tag: 5,000 yuan, that’s $725 U.S. That’s way over the line for a small Chinese business.

Nanchang has about 600 Internet cafes for its approximately 4-million citizens. In China, for most people, Internet cafes are still the way they use to connect with the Internet. China made be home for Lenovo and many other PC vendors, but you’re not going to find PCs and broadband in most homes.

That said, no one’s getting rich from the Internet cafes. They’re small mom and pop businesses. They can’t afford $725 for an operating system and they’re letting the officials know about it. Unfortunately, it’s not doing much good. One said, “When you talk to officials from the Culture Department, they tell you, ‘If you’re willing to pay, pay; if not, you have the option not to pay.’ Hearing words like that turns your heart cold. We really can’t make a living.” In other words, you can either pay to play or you can go out of business.

MySQL 5.1 released with crashing bugs

Wow. Talk about your disgruntled employees. Michael ‘Monty’ Widenius, MySQL’s founder and, for the moment, still Sun’s CTO for its MySQL division, greeted the GA (general availability) of the latest version of the popular open-source database system MySQL 5.1 by writing, “I am asking you to be very cautious about MySQL 5.1 is that there are still many known and unknown fatal bugs in the new features that are still not addressed.”

This is the GA release!? This sure doesn’t sound like a ready to go to work software release to me! In fact, according to Widenius, the long-delayed release of MySQL 5.1, is anything but ready for production use.

Widenius went on to write in his blog, Monty Says, “If you are using MySQL 5.1 just as a ‘better’ version of MySQL 5.0 and you don’t plan to use any of the new features in MySQL 5.1 then you are probably fine to try out MySQL 5.1. You should however not put it into production without testing it fully, preferably by running it on a couple of slaves for some weeks. It may even be the best to wait for a couple of minor/patch releases before putting the MySQL 5.1 server into production.”

But, Widenius goes on, “Don’t expect that all critical bugs that you may have encountered in 5.0 to be fixed in 5.1. Even if we have fixed a big majority of the bugs from 5.0 some really critical ones still haven’t been addressed.” That’s not exactly reassuring.

Atheros Wi-Fi goes open-source, Linux friendly

If you use Wi-Fi on your laptop, there’s an excellent chance you’re using Atheros chipsets for your wireless networking. Atheros’ silicon is in gear from Linksys, D-Link and Netgear to name but a few vendors. However, although Atheros has been popular, they haven’t always been friendly to open-source and Linux developers. That has been changing over the years and now, thanks to Sam Leffler, noted open-source developer, the HAL (hardware abstraction layer) for Atheros’ ath5k and ath9k chip families.

This is another major step in opening up hardware for Linux, Free BSD, and the other open-source operating systems. Earlier this year, Atheros released an open-source driver for its latest 802.11n chipsets.

Picasa 3: Great Linux photo software

I have a confession to make. There’s no software on earth I can’t make dance and sing… except for photography programs. Whether it’s Adobe Photoshop CS4 on a Mac or GIMP 2.6.3 on Linux, I’m a klutz. So, when I need to make my holiday photos look halfway decent, I try my best with easy to use photo programs like Photoshop Elements 7 or Google Picasa. While I’d like to see more Adobe programs, on Linux with Google’s new release of Picasa 3 for Linux now here, I’m in no hurry to see Photoshop Elements on Linux.

Don’t get me wrong, Picasa doesn’t has all of Elements’ features. After all, these days Elements is really just the low-end version of Photoshop rather than a program for casual photographers like yours truly. For me, and for the millions of others who find getting rid of red-eye in photos the biggest challenge they’ll ever tackle, Picasa is more than enough program.

I installed the new Picasa, which like all Google programs is a free download and labeled as beta software on two systems. The first is my new main Linux desktop system. This is a Dell Inspiron 530s, powered by a 2.2GHz Intel Pentium E2200 dual-core processor with an 800MHz front side bus, 4GB of RAM, a 500GB SATA drive, and an integrated Intel 3100 GMA (Graphics Media Accelerator) running the Debian-based SimplyMEPIS 8. My other test computer is my openSUSE 11 powered ThinkPad R61 with a 2.2GHz Intel Core 2 Duo processor T7500, 2GBs of RAM, an 80GB hard drive and an integrated Intel 965 GMA.

Underneath the hood, Picasa isn’t a native Linux application. It’s actually a Windows program running under Wine, an open-source version of the Windows API (application programming interface). No matter, on both computers, the program ran flawlessly. And, better still, it did a flawless job of making my photos presentable.

The world’s fastest computers are Linux computers

There are fast computers, and then there are Linux fast computers. Every six months, the Top 500 organization announces “its ranked list of general purpose systems that are in common use for high end applications.” In other words, supercomputers. And, as has been the case for years now, the fastest of the fast are Linux computers.

As Jay Lyman, an analyst at The 451 Group points out, Linux is only growing stronger in supercomputing. “When considered as the primary OS or part of a mixed-OS supersystem, Linux is now present in 469 of the supercomputer sites, 93.8% of the Top500 list. This represents about 10 more sites than in November 2007, when Linux had presence in 91.8% of the systems. In fact, Linux is the only operating system that managed gains in the November 2008 list. A year ago, Linux was the OS for 84.6% of the top supercomputers. In November 2008, the open source OS was used in 87.8% of the systems. Compare this to Unix, which dropped from 6% to 4.6%, mixed-OS use which dropped from 7.2% to 6.2% and other operating systems, including BSD, Mac OS X and Windows, which were all down this year from the November 2007 list.”

Microsoft is proud that a system running Windows HPC Server 2008 took 10th place… behind nine supercomputers running Linux. Even then, this was really more of a stunt than a demonstration that the HPC Server system is ready to compete with the big boys.

You see, there are no Microsoft programming tools to write supercomputer compatible applications. That will come years from now with Visual Studio 2010 and when Microsoft’s F# is more than a research project language. In short, Windows HPC isn’t ready for prime-time.

Red Hat’s winning Fedora 10 Linux arrives

What’s the difference between a cutting-edge and a bleeding-edge product? A cutting-edge product is the newest of the new and it works. A bleeding-edge product is the newest of the new and it ‘sort of’ works. You’ll end up making a bloody mess of yourself with most bleeding-edge programs. Fedora 10, however, is a true cutting-edge Linux distribution.

Paul Frields, Red Hat’s Fedora project leader, told me that this ‘decade’ release of Fedora was the best ever without any significant bugs. Yeah. I’ve heard that before.

You know what though? Based on my early work with Fedora 10, Frields’ right. This is one clean, mean cutting-edge Linux distribution.
