Hello dear readers and attendees,

This is the post that I will be/ will have been referencing during my presentation to the Seattle Central Community College’s Byte club on Thursday, December 10th at 1500-1630.

I will discuss some of the bits and pieces of some industry standard platforms which I’ve developed, deployed, maintained, managed, co-operated, administered and replaced. We can discuss some of the patterns that work well in the industry, and some that are a bit harder to …

How to Purchase [Benchmarking] Hardware on a Budget
+0 Vote Up -0Vote Down

One of my goals at Acmebenchmarking is make sure I'm running on hardware that is representative of real-world infrastructure, while at the same time doing it as inexpensively as possible.

To date I've been running on two custom built "desktops" (for lack of a better term). Both have an Intel Core i7 4790K processor (quad core plus hyperthreading, 4Ghz), 32GB RAM (dual channel), and a quality SSD. They are named acmebench01 and acmebench02.

Alas, it is time to expand. MUST...PURCHASE...MORE...HARDWARE!

In order to maintain the inexpensive theme I tend to buy used hardware, my goal on …

How to improve InnoDB performance by 55% for write-bound loads
+2 Vote Up -0Vote Down

During April’s Percona Live MySQL Conference and Expo 2014, I attended a talk on MySQL 5.7 performance an scalability given by Dimitri Kravtchuk, the Oracle MySQL benchmark specialist. He mentioned at some point that the InnoDB double write buffer was a real performance killer. For the ones that don’t know what the innodb double write buffer is, it is a disk buffer were pages are written before being written to the actual data file. Upon restart, pages in the double write buffer are rewritten to their …

Linus on Instantiation and Armadaification
+0 Vote Up -1Vote Down

I feel a sense of pride when I think that I was involved in the development and maintenance of what was probably the first piece of software accepted into Debian which then had and still has direct up-stream support from Microsoft. The world is a better place for having Microsoft in it. The first operating system I ever ran on an 08086-based CPU was MS-DOS 2.x. I remember how thrilled I was when we got to see how my friend’s 80286 system ran BBS software that would cause a modem to dial a local system and display the application as if it were running on a …

A Few Thoughts on OSCon and the Open Source Community
+1 Vote Up -0Vote Down

This past week I attended OSCon, the annual conference for open source’s true believers. And there was a religious fervor in the air, particularly from the point of view of someone more accustomed to Oracle conferences.

And if open source is the religion, proprietary closed-source companies are the devil. That having been said, I was surprised how virtually all large companies were demonized. Even long-time defenders of open source like IBM were ignored at best. That didn’t prevent them from coming though, with Microsoft and HP in particular with high-profile sponsorships and PR …
