Previously, in “Thoughts on Thoughts on Drizzle” I theorized that one of the major reasons why we did not see lots of people jumping at stored procedures in MySQL was that it wasn’t in their native language (for lack of a better term). We’ve seen External Language Stored Procedures for MySQL that let you write stored procedures in some other languages…. but I felt something was missing.

Firstly, I wanted a language I was really familiar with and comfortable writing complex things in.

Secondly, it should be compiled so that it runs as fast as possible.

Thirdly, it shouldn’t just be linking to a pre-compiled library (drizzle function plugins do that …

CMake is a cross-platform, open-source build system, maintained by Kitware, Inc.

From the CMake.org home page:

CMake is a family of tools designed to build, test and package software. CMake is used to control the software compilation process using simple platform and compiler independent configuration files. CMake generates native makefiles and workspaces that can be used in the compiler environment of your choice.

It has been used for building the MySQL Server on Windows since MySQL 5.0 – the initial CMake build support was added in August 2006.

We’re continuing to see signs that the dominant GPL open source license may be fading from favor among commercial open source software players. The latest move away from the GPL comes from content management software vendor Alfresco, which is moving to the LGPL after originally releasing its code under the GPL three years ago. The reasoning for the shift, according to Alfresco CEO John Newton, is the company sees greater opportunity beyond being a software application, particularly given the emergence of the Content Management Interoperability Services standard. Alfresco won mostly praise for its move, and it does make sense given where open source is going these days.

I believe the emerging trend away …

#define READ_ALL           1       /* openfrm: Read all parameters */
#define EXTRA_RECORD            8       /* Reservera plats f|r extra record */

and later on….

  if (prgflag & (READ_ALL+EXTRA_RECORD))
    records++;

Feel free to think about that for a second.

(I have an urge to add this to questions asked in a job interview…)

I just uploaded a new tarball for sar-sql containing a few bug fixes, overall code improvements. I also added options to get a partial snapshot of SHOW SLAVE STATUS and SHOW MASTER STATUS. I chose only a few columns to avoid over complicating the project.

I plan one more round of heavy code changes, but no new features until I can stabilize the code enough to release it as beta.


Feel free to visit the project page in Launchpad to comment on the Blueprints, report new bugs and participate through the Answers section.

Thank you very much to Patrick Galbraith who provided some ideas on the best way to solve some of the coding issues.

Enjoy the …

I thought it’d be nice to discover new photos on flickr using your favorite photos and the people who also favorited those photos, and the favorite photos of those who also favorited my pictures. Still with me?

It’s actually a quite simple code (about 500 lines, check it on github: discovr), but it’s terribly slow. Some possible reasons:

• Way too much data. I’ve found people with around more than 18000 favorites, and there are photos with more than 2k fans. After limiting to 50 last …

This blog post is a by-product of my preparation work for an upcoming talk titled "Why you should be using a distributed version control system (DVCS) for your project" at SAPO Codebits in Lisbon (December 3-5, 2009). Publishing these thoughts prior to the conference serves two purposes: getting some peer review on my findings and acting as a teaser for the actual talk. So please let me know — did I cover the relevant aspects or did I miss anything? What's your take on DVCS vs. the centralized approach? Why do you prefer one over the other? I'm looking forward to your comments!

Even though there are several distributed alternatives available for some years now (with Bazaar, git and …
