Parallel BZIP2: pbzip2

July 7th, 2010 Andrew Rankin No comments

I find myself compressing files for archival purposes constantly – today I was sitting, waiting on one such compression on a SMP box and thought it seems silly that bzip2 does not use more than one CPU. After a quick flip through the man page for bzip2 I found no way to force it to use more than one core. A quick web search yielded pbzip2 (http://compression.ca/pbzip2/) – another project that does indeed allow you to use more than one CPU for compress and decompression of bzip2 files.

Glovebox v0.2.1 Released

June 13th, 2009 Andrew Rankin No comments

I’ve released Glovebox Version 0.2.1 on Sourceforge.  It has a few bug fixes as well as the correct database schema included. Other changes include:

  • Modified JavaScript so it would load & function in IE
  • Changed “class” to “clas” within JS, Perl, and the database. IE didn’t like using the word “class” as a variable name, changed else where for consistency.
  • Stopped opening of “right-click” menu when pressed on an interface folder
  • Fixed DB Schema to include basic information for default OIDs and Interfaces.
  • Modified Apache configuration so SSIs would work correctly in Apache 2, changed the SSIs to only execute on .shtml files
  • Renamed index.html to index.shtml

There is a database change, so you must run the sql file located in the upgrade folder!

You can download it here.

Glovebox: My Solution to Managing Servers

May 8th, 2009 Andrew Rankin No comments

When I started in the “Technology” department at my current employer, I found myself apart of a team that was tasked with taking care of hundreds of IBM blade servers, and tens of other IBM system x servers.  For the most part we could keep up with our servers by where they were in our monitoring software, but if we needed to know exactly where they were in either a blade center, by remote console name, or what Domain-0 they lived on for our Xen based virtual machines – we had to relate back to a usually out of date spreadsheet that showed where to go.
