Congratulations Xen

Posted on June 2, 2011 by M@

Xen is now in the mainline kernel, where KVM has been since Feburary 2007. Xen is still a completely separate kernel, with completely separate interfaces. Xen may now be in Linux, but still is not Linux.

A Perl Thread-Pool

Posted on February 24, 2011 by M@

I’ve been doing a lot of large-system coding with Perl ithreads lately.  This thread model has been scaling very well on very high-throughput operations in conjunction with well-placed yield() calls in the thread-handler. This isn’t rocket-science, but it handles some … Continue reading →

Installing OpenQRM 4.7 on Fedora 14

Posted on December 23, 2010 by M@

OpenQRM 4.7 doesn’t compile cleanly on Fedora 14 (x64, but I don’t think that matters for this bug), and coercing it to do so isn’t the cleanest trick. The problem is actually with Busybox 1.14.2 that is automatically downloaded and … Continue reading →

Build A Moat

Posted on August 24, 2009 by M@

Your app is falling down because it’s been Slashdotted. Your database can’t handle the query surge. Your app is highly dynamic so tossing up a static front-page, using Akamai, etc. isn’t viable. How can you handle 30kviews/s? You have a … Continue reading →

FOSS’s Microsoft Hatred "a Disease"

Posted on July 27, 2009 by M@

Purloined wholesale from SlashDot, and reposted. The hypocrisy of a vocal minority of FOSS-purists has been overwhelming. As Linus accurately points out, we’re all in it for selfish reasons. No one likes working on the boring bits, and we all … Continue reading →

Levanta Intrepid

Posted on April 22, 2008 by M@

[NOTE: This was written a while ago] [UPDATE: Levanta is toast]. Remember LinuxCare? That ambitious start-up back-in-the-day that wanted to revolutionize Linux support? Yeah, they died. But from the ashes rose Levanta. Unlike LinuxCare, Levanta has been studiously working on … Continue reading →
