Introducing WP Trainer

Posted by in WordPress > Plugins

Today, the birthday present from my parents arrived, a Garmin Forerunner 305. Someone on the track team, during my senior year, had one of the old 101s that weighed three times as much and are twice as big. But, despite its size it worked well. In fact, it worked well enough for the cross country coaches to purchase two 201s for the use of the team for keeping track of distances ran, instead of those running wheels. That’s where the idea to get it for me came from.

The 305 includes a heart rate monitor and records it along with time and other various stats during a workout. I have yet to try it out but tomorrow I’ll take it for a test run. Tonight, I charged it and installed the Garmin software, which defiantly feels lacking. What is good about it though is data exporting, and with that a WordPress plug-in will be made for keeping track of runs. Naturally, this won’t be available for some time, but it will be a free and powerful alternative to MotionBased.

WP Trainer will first work with the Forerunner series training GPS, but eventually support for the iPod + Nike setup, which is a really neat setup and defiantly less expensive as well. iPod + Nike has one drawback however, as it is not a GPS system, route tracking will have to be manually done by the user. With the Forerunner units, uploading the exported data should allow an auto generation of a path overlay on top of Google maps. Since I do not own a iPod or the Nike + iPod Sport Kit this setup will not be the emphasis of this plug-in (initially that is, I’m sure I’ll have access to the needed equipment when the time comes). More details will be revealed as I begin to implement things. This blog will be the test bed for this plug-in so if things get flaky that probably is the plug-in.

We’re Back (Again)

Posted by in Weblogs.us

After a brief absence due a hardware failure, Weblogs.us is back. A slue of new hardware accompanies the return. From this time forward service outages should be rare (unless someone gets Dugg).

JD installed a new 8 core Woodcrest server with 8GiB ram for the new Apache/PHP/file server, and the SQL server was replaced as well. Since some nasty traffic was making it to the old Apache server, a dedicated hardware firewall was installed a good thing all around as the bad traffic was at times taking up to half of the network activity. Look forward to some more interesting updates here as some projects wrap up and the semester winds down.

One final thing, Happy Birthday James (jmweirick)! (This may be off by a day or so)

Forget MATLAB

Posted by in General

Yep, forget it, use GNU Octave instead. For calculus 3, rather linear algebra and differential equations, there is a lab which requires the use of MATLAB to do things that can get ugly. One particular use is for Gaussian elimination for finding values of several variables that solve a set of equations.

Occasionally, a write up is required for certain parts of the problems completed in lab. Checking work previously done in lab when doing the write-up is always reassuring. Going back to the computer lab is not convenient, and the 200USD that it costs for a student license of MATLAB can go to better use. That’s where GNU Octave comes in; it’s GNU’s MATLAB replacement that accepts nearly all of MATLAB’s commands. For Gaussian elimination, Octave sure beats writing a PHP script to do it (which I did on Monday).

On a side note, getting Aptana to work on Gentoo is fairly painless, though its installation doesn’t comply with the Gentoo philosophy. Maybe when it comes out of beta I’ll help get it into portage. I’ve also written a simple bash script for loading Aptana, which will be available in the tools section on this site once I figure out exactly where Aptana’s files should go to be consistent with Gentoo’s installation methods. Since at the U of M they don’t automatically load the modules necessary to run MATLAB at login, and the matlab command doesn’t do it automatically I’ve written a simple bash script that should take care of this. It’s available for download in the tools section.

Sammy’s Banished

Posted by in Enemy of the Spammers

Sammy Kamkar, the one who over a year ago unleashed an exploit on MySpace that caused anyone who viewed his profile, or his friends’ profiles to automatically request to be his friend. MySpace filed a civil suit against Kamkar, who plead guilty and is now banished from the Internet for a classified amount of time. The plaintiffs claimed that they are “committed to protecting our community from any abusive misuse of the site.”

Frankly, after reviewing the code and reading the explanation of his method, the hack only worked for IE and certain versions of Safari. In reality the exploit was of both the browsers and MySpace, his code should never have executed in the browsers. News Corp. should go after Microsoft as they are equally responsible for this exploit. Regardless, it’ll be interesting to see how they will go about keeping him off the Internet.

In other news, Boston needs to get a brain. Overreacting to the ten or so PCBs with LEDs attached and a black plastic bag protecting the batteries was idiocy. If the police can’t tell the difference between a bomb and a LED sign, how are they supposed to do their job? Seriously the media needs to stop spreading misinformation and disinformation before the people revolt against them, oh wait that’s already about to happen (the Internet, YouTube, p2p, etc).

Not Tonight

Posted by in General

It won’t happen tonight, or tomorrow.
Not tomorrow night, or the next.
Not next week, month, year.
Not now.

It will happen when it does,
When it has matured,
When it’s complete,
When it arrives.

Do not fret nonetheless,
I promise it shall come to pass.
Just not now,
Not tonight.
