XBeta Wiki


March 29, 2009

Since last December, xbeta has been served by a Debian Linux VPS hosted by Linode. The specs of the new server, particularly the network throughput and CPU allocation are much better than before. Additionally, there have been efficiency improvements in Instiki itself. All of this seems to have improved the performance of the wiki significantly. This is not to say that the site was slow before, only that now it should be even faster. —Jason Blevins

New Logo, New Server, New Database

February 27, 2008

Thanks to the textext extension for Inkscape and Sam Ruby’s svgtidy, the site now has a pure SVG logo, weighing in at 517 bytes, and a favicon.

The site is now running on virtual private server hosted by A2 hosting with a fresh, streamlined installation of Ubuntu. It’s still being served by Mongrel and proxied through Apache but I’ve migrated from MySQL to SQLite just to keep things simple. —Jason Blevins

I have upgraded to the latest versions of Instiki and itexToMML (version 1.3.3). Recent revisions of Instiki are now based on Rails 2.0.2. —Jason Blevins

LaTeX and PDF export

October 4, 2007

TeX export (via the TeX link below) has been greatly improved. The template now includes macros for just about every itex command that is not a standard (AMS)LaTeX command. In almost all cases, the generated tex file should compile as-is, as long as the AMS math packages and the txfonts package are available. These packages are widely available and are included in the standard LaTeX distributions, teTeX and TeX Live.

I have also enabled PDF export (via the PDF link below). The PDF file is simply generated on the fly by pdflatex from the exported TeX file. There are still a few minor cosmetic issues, but this is a good option for printing. —Jason Blevins

Mongrel Acceleration

March 1, 2007

xbeta is now running with Mongrel acceleration. Mongrel is a fast HTTP library and server for Ruby web applications. Pages should load significantly faster than with the previous, unaccelerated CGI dispatcher. —Jason Blevins

xbeta Comes Alive

February 20, 2007

I registered the domain xbeta.org almost a year ago with the intention of creating an Econometrics-oriented website. I had in mind a site with information about using high performance programming languages in Econometrics and related code and packages. Instead, through a series of fortunate events, xbeta.org is now the home of the xbeta wiki.

I was recently introduced to Ruby and Rails and I had considered attempting to add some kind of LaTeX or MathML functionality to Ruse, another Ruby on Rails wiki. Luckily, the very same day I stumbled upon Jacques Distler’s MathML-enabled branch of Instiki. It was exactly what I was looking for and a perfect fit for the site. Setup is minimal. The site was up and running in about ten minutes. —Jason Blevins
