Thoughts and Ramblings

General things I find of interest.

Perian Woes

Well, we had some fun with Perian today. First it started when macupdate decided that they were going to post a fake 1.0 of Perian. You can read the details if you like. Since this is clearly something we didn’t want, we had to figure out how it happened. My guess is that someone saw the new website design in development within the subversion repository, clicked the download link that was there, and noticed it download a version later than what we have on the website.


Why Me?

Why did I get a email like this?

hi, my name is ****** from Brazil. I am a electrical enginnering student and I would like to know if someone has a program that calculate the transient stability with values of internal voltages of the machines. My program calculate a Load Flow for systems 9-bus and 14-bus, but need to find the values of pre fault and post fault and Variables of state e equilibry of machines I need simulate three phase short circuit considerated Fault period (tch) and generate Grafics angle X time and Grafics velocity X time I need to simulate a three phase short circuited with fault period tch and generate graphics with the results of anglextime and velocityx time bars voltage of system and internal voltage of generators. I have a doubt. What is the best language to develop this kind of program?Delphi or C++ Builder? Thanks


New Safari

Well, Apple released a beta of Safari 3.0 and so I decided to try it out. I had almost forgotten why I switched to Firefox until I was doing this post. Safari’s javascript was not up to par to work properly with wordpress, so I had to switch to a browser that was. Now, wordpress is hardwired to disable features on Safari, so I had to make it lie and claim it was Firefox in order to test them. Seems to work just fine.


Seeing the Railroad Bridge

It was nice to pull out the camera again after such a long hiatus. My parents took me to see an old railroad bridge across the Guadalupe River near Comfort, TX (GPS cords: 29°58'36’’ N 98°50'45’’ W). Anyway, here is a shot of the bridge from below:

We had to contend with several “Road Closed” signs and “No Parking” signs in order to see the thing. There was one case where a sign said that the road was closed at a fork in the road, leaving it ambiguous as to which one we should take. Anyway, you can clearly see why the road was closed below:

A tree down and about a foot of fast moving water over it. Don’t think I would want to cross that. At least the designers of the bridge had the sense to build it much higher than the river so it was safe from the recent flooding.


Nearing Release

Well, Perian is finally nearing a release. I wonder how much press we will get over this one, since it is finally hitting version 1.0. Chris (project manager) seems to think that Perian will be bigger than Adium (which he also manages). Considering how well version 0.5 has been received (over a quarter million downloads), I think I now believe him. Then we get to start work on version 1.1, which will include optimizations to what we did in 1.0.
