Why I Don’t Use Linux
After reading the “Windows Is Free” article earlier, I felt compelled to write my own blog entry. I do agree with the analysis to a point, but there is a major point where I differ. The “Just Work” factor. Now I know, I know, the newer versions of Ubuntu and OpenSuSe and Mandriva do work with most hardware. But most, isn’t enough.
Case #1. A few years ago I tried to install Red Hat 4 onto my box computer. Right off the bat, my wireless connection did not work. My video card had no 3d support. My sound card did not work at all. I couldn’t access any of my MP3s or videos because there was no fat32 support short of a package download, which I couldn’t do because of the aforementioned wireless problem. That install lasted for 5 days while I toiled away trying to solve any of the numerous problems I was having.
Dell hails 2008 as the year of the corporate Linux desktop
The advent of desktop virtualisation will provide the missing link for Linux to shine on the corporate desktop, Dell chief technology officer Kevin Kettler predicted in a keynote speech at the Linuxworld conference in San Francisco.
“A lot of people are predicting that next year could be the year where we really see an explosive growth of Linux on the desktop in business applications, ” Kettler told delegates.

MySQL stops providing Enterprise source 4free
For the past few months I have been providing “Red Hat”-style RPMs of the newest MySQL versions, including the Enterprise-only releases. Unfortunately it looks like that practice is going to come to an end. The developers of MySQL have decided to change the release policy of the Community version and the availability policy of the Enterprise sources.
On the first point, the stable release of MySQL (currently 5.0) will receive “at least 2″ binary releases per year and quarterly source releases. It seems that the intention is to release more frequently only if there is a critical flaw to be fixed. In addition, whenever a new GA is released (like the soon-to-be-released 5.1), there will be monthly binary builds until the product reaches suitable stability levels and is deemed “mature”.
As to the second point, up until now the source code for the Enterprise releases has been posted on the main MySQL FTP server for anyone to download and compile themselves. Unfortunately (for us), they’ve now decided decided to restrict the download of the Enterprise sources to paying Enterprise customers, meaning that there will no longer be a free way to upgrade your MySQL install with the monthly bug-fix releases. For those of you about to start screaming that this is a GPL violation, it’s not. They’re not saying that the project is now closed-source, just that they aren’t going to distribute that source to anyone but paying customers.
If something changes I’ll start building the releases again as I have been. If not, don’t worry, I’ll still build new releases every quarter so you can keep your systems up-to-date without having to worry about changing package structures by using the RPMs available directly from MySQL.
