FreeIPA: Active Directory for Linux?

Note to self: explore FreeIPA. Someone on Serverfault suggested it and said it was what AD is for Windows. If it is, it would relieve me of LDAP hell. Too long for this blog post, but I spent about a week (or more) full-time to get an LDAP setup working, with all security measures in place. It involved diving into source code, discovering and reporting Ubuntu documentation bugs, etc. An experience I don't care to repeat. Read More »

Blackberry Enterprise Server issues

I've had some issues with my Blackberry Enterprise Server. Some users say their mail is not synced. Others are reporting calendars being messed up. Just jotting down some memory aids. Read More »

Checking SMART status on a 3Ware controller with smartctl

A RAID controller hides the physical disks from the operating system, so it's harder to query the SMART data. Luckily, smartctl has a way to do it: Read More »

Adding foreign key constraints to PowerDNS default schema

In an earlier post I made, I described how to manually create the SQL schema, because it didn't itself. When I installed Power DNS 3.1-4 on a Raspberry Pi, I noticed it had created the scheme itself this time. However, it did not make the foreign key constraints. This is dumb. I regularly need to remove domains from the DB and I don't want stale or incorrect references as a result. Read More »

Xen VM: Frag is bigger than frame

Increasing the number of reps on my pull-ups

I'm growing increasingly frustrated with my inability to increase the number of pull-ups I can do in one set. And, after so many years, I'm still not even close to doing a single one-hand pull-up or one of those muscle-ups all the niggers on YouTube seem to be doing these days. That's why I'm going to let one of those black dudes guide me and my puny, little white frame: Read More »

Converting a Subversion repository to Git

Design: The Scourge of the Web

When the printing press was invented, we had the understanding that text is best read when contrast is high. They didn't use black ink on paper for nothing. I bet they didn't even consider any other color. Read More »

Creative Audigy 2 ZS design flaws

I would really like to know what the designers at Creative Labs have in mind when they design sound cards. Their cards seem to be broken by design. The Live card was bad enough with its random collection of DACs and DPS's, but the Audigy 2 ZS seems no better. Aside from the fact that it's advertised as 96 kHz and 24 bit, which it isn't, it has serious design issues. I had some sound anomalies, so I decided to measure and test. I found: Read More »
