Earlier this week I posted how OpenJDK was knock, knock, knockin' on Lenny's door. At that time I also mentioned how it was already in Ubuntu and Fedora.
What I failed to mention, however, and was right under my very nose was that fact that OpenJDK had already made it into OpenSUSE 11. Thanks to MySQL Euro-community manager and former SUSE employee Lenz Grimmer, I was …

[Read more]It seems almost churlish to wonder whether Google could be even more successful than it already is with a different strategy, but the company’s approach to open source and open development has come into focus in recent weeks.
On last week’s podcast we discussed whether the company should see the AGPL as more of an opportunity than a threat following Jay’s post about the company releasing more code under open source licenses.
Nik Cubrilovic over at TechCrunch, meanwhile, has written an interesting …
[Read more]Sun continues to take a performance pounding, and the rumors of replacements, layoffs and revamps are beyond swirling and now perpetuating skepticism of the company. It strikes me as odd that Sun, which has embraced open source and is also the defacto leading corporate open source software contributor, is continually dogged by doubts about its transitions and tenures despite well-respected technology and participation in open source. Part of this lies in the company’s continuing dichotomy in strategy — a reference to tepid support for Linux and continued preference for and focus on Solaris. This is a large part of Sun’s ‘handicap,’ IMHO when it comes to Linux and open …
[Read more]I was at a client site with Yves Trudeau ( another MySQL consultant ) and the client had purchased a brand new top of the line 16 core server. It is well documented in many places that scalability beyond 4-8 cores with innodb is less then optimal. We were asked for a ballpark on the performance of a 16 cores vs an 8 cores, and specifically if their were any options to reduce the number of cores the mysqld process could use. We decided to benchmark this using DBT2. To do the test we ended up setting the CPU affinity of the mysqld process. You can set this with the following command: taskset. Yves ended up trying the same DBT2 tests for 1-16 cores. I won’t write too much about the scalability here, as I said their are way better resources out their that can explain it better, but what I wanted to do is post the results of …
[Read more]Having a Google account is sometimes useful in ways you hadn’t planned for. For example, at a few different employers I’ve been at, I’ve had to prepare for reviews by providing a list of accomplishments to my supervisor. One decent tool for generating this list is email, though it can take some time. Another useful tool is the Web History feature of your Google account.
Though this isn’t necessarily indicative of everything I’ve accomplished in the first half of 2008 per se, it’s definitely indicative of the types of things I’ve generally been into so far this year, and it’s interesting to look back. What does your Web History say?
Since it took me over an hour to gather this together, I thought I would relay it here. To install the latest version of Darwin Streaming Server (6.0.3 at time of writing), you need to do the following:
I am happy to announce that a new version (0.9) of mylvmbackup has been released. This is the first release since the source code has been moved from Subversion to Bazaar and is now hosted on Launchpad.net. I would like to thank Robin H. Johnson and Patrick Hahn for providing the patches that contributed to this new release!
mylvmbackup is a tool for quickly creating backups of MySQL server's data files. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, makes an LVM snapshot of the volume containing the MySQL data directory, and unlocks the tables again. The snapshot process takes only a small amount of time. When it is done, the server can continue normal operations, while the actual file backup proceeds.

[Read more]I’ve been working with what I used to call “utility computing” tools for about 6-9 months. However, for about the past 2 months, I’ve been seeing the term “cloud computing” all over the place, and there is so much buzz surrounding it that it’s reaching that magical point best described using Alan Greenspan’s words: “Irrational Exuberance”.
When Alan Greenspan used those words to describe the attitudes of investors toward the markets, what he was basically saying was that there were people who didn’t really know what they were doing, putting more money than they ought, into things they knew relatively little about. Further, he was saying that the decisions people were making with regards to where to put their money were a) bad, or at least b) not based on sound reasoning, or the ‘facts on the ground’.
This, I think, is where we are at with “cloud computing”. The blog post that put me over the edge is …
[Read more]I'm back from my week of vacation and am ready to pick up where I left off with the interviews I conducted at the Red Hat Summit/FUDCon last month. After today's, I will have three left: Dennis Gilmore, Max Spevack and Chander Kant of Zmanda.
The Honourable James Zemlin
On the first day of the Summit I was able to grab my buddy Jim Zemlin, the Executive Director of the Linux Foundation for a spirited discussion about the Foundation, Linux and a bunch more.
My interview with Jim (15:55) Listen ( …
