The Backstory:

At work, we have a division dedicated to staffing and recruiting IT and Engineering professionals. This division has their own website, which is designed to market to employers seeking these types of candidates. Naturally, these types of candidates will wander and stumble upon this site even though it’s designed to attract employers. In [...]

gparted, dd, and ghex2 – Oh My! To The Rescue!

travis.hegner — Thu, 14 Apr 2011 14:01:30 +0000

So, I was messing around with an XP virtual machine that was out of disk space. For some dumb reason, I thought 4GB of hard disk space was plenty for XP when I built it. Well here we are a few years later, and M$ has release so many service packs and updates that the [...]

travis.hegner — Mon, 07 Mar 2011 00:46:41 +0000

Good evening,

You’ll have to forgive me if I seem a bit nervous, I’m not used to being in a room where there are more people than computers.

Since this is a wedding and all, I decided that we [...]

Hey Everybody!

As promised, though a little later than I’d originally hoped, here is a quick blurb on what I’ve done to make my fully distributed Hbase instance run with a little bit more stability.

hbase.hregion.max.filesize � Default: 268435456

I am pleased to report that the 9.10 release of Ubuntu is available for Beta testing. I have had the Alpha running on a test machine for several weeks now with daily updates applied. My First impressions of the release are pleasing, but I haven’t done too much with it yet. The first thing [...]

OK, OK, I know what you’re thinking. “Where has this guy been with some more of this hadoop goodness that we just can’t get enough of?” Well, I am (finally) back, and you’ll be happy to learn what I brought with me: A whole mess more Hadoop and Hbase knowledge that I can’t wait to [...]

Hadoop 0.20 on Ubuntu Server 9.04 Jaunty

travis.hegner — Mon, 29 Jun 2009 17:08:31 +0000

In the last few weeks, I have become completely fascinated by clustered computing, and solving very large complex problems with a somewhat large number of cheap computers. While researching more efficient ways to store and search through my employers internal resume database, I stumbled onto this software called Hbase, which is a column-oriented database, modeled [...]

Authoritative DNS

As much as I love exploring and learning the newer protocols and technologies like SIP, and Enterprise Virtualization, there is something to be said for those standards and protocols that the internet is built from on and designed around. It is quite refreshing to work with a protocol that is not under constant revision and [...]

In an effort to make things a bit more redundant at my work place, I have implemented PostgreSQL 8.3 warm stand-by replication, as outlined in the pgsql 8.3 manual.The manual leaves the possibilities for implementation pretty wide open, which is good for making things scalable, and applying the process in many different ways, but it [...]

Ubuntu Server 9.04 Jaunty: open-vm modules fail to build

I have decided to start upgrading from Ubuntu Server 8.10 Intrepid to Ubuntu Server 9.04 on all of my server machines. In 8.10, I was able to get the open-vm-tools to build and install, but they suffered from a bug which caused the vmware-guestd service to crash soon after starting. This was mildly acceptable and [...]
