Designing for high performance

Here's the thing about high performance: you can't just bolt it on at the end. It's got to be baked in from day one. No doubt those of you who are experienced developers are now invoking the venerable Donald Knuth, who once said, "Premature optimization is the root of all...

Visualizing Build Processes

The other day I was waiting for my continuous integration build to finish. Think about that a minute. See anything wrong with that statement? I was waiting for a continuous integration build to finish. The whole point of continuous integration is to detect integration errors as quickly as possible. After...

How scalable is SCons?

The marquee feature in ElectricAccelerator 5.0 is Electrify, a new front-end to the Accelerator cluster that allows us to distribute work from a wide variety of processes in addition to the make-based processes that we have always managed. One example is SCons, an alternative build system implemented in Python that...

Automating around scarcity by using virtual resources

[posted on behalf of Usman Muzaffar, who is on a long flight with no WiFi] Here's a sobering truth that shows up often in software automation: people are way better at sharing stuff than computers are. For example: say you have a scarce resource, like a box with special hardware...

How to quickly navigate an unfamiliar makefile

The other day, I was working with an unfamiliar build and I needed to get familiar with it in a hurry. In this case, I was dealing with a makefile generated by the Perl utility h2xs, but the trick I'll show you here works any time you need to find...

Seven lessons from seven years at Electric Cloud

We wrapped up the 2009 Electric Cloud Customer Summit a couple weeks ago. Like last year, I left refreshed and reinvigorated after hearing so many customers' stories. Comments like, "Developer builds are now measured in seconds [with Accelerator]. Nobody does local builds anymore," and, "ElectricAccelerator will give you better performance...

What is SparkBuild?

At the 2009 Electric Cloud Customer Summit we introduced SparkBuild, a free gmake- and NMAKE-compatible build tool. SparkBuild is now in public beta, and several people have asked us for some more explanation: what is SparkBuild and why should I care? I thought I'd take a crack at answering those...

Subbuilds: build avoidance done right

I've heard it said that the best programmer is a lazy programmer. I've always taken that to mean that the best programmers avoid unnecessary work, by working smarter and not harder; and that they focus on building only those features that are really required now, not allowing speculative work to...

Private clouds: more than just buzzword bingo

A friend pointed me to a blog in which Ronald Schmelzer, an analyst at ZapThink, asserts that the term "private cloud" is nothing more than empty marketing hype. Ironically, he proposes that we instead use the term "service-oriented cloud computing." Maybe I'm being obtuse, but "service-oriented" anything is about the...
