SecondBar is Nice

I have a very nice set up now at work with a Retina 15″, and a Thunderbolt 27″ display. But the single menu on a single monitor is not so nice. SecondBar adds a copy of the menu to the second monitor. I find SecondBar from very handy and recommend it. Thanks! Remind self to drop the fellow some quatloos.

Dashcode Bug – Disappearing widgets

The quick answer is from the terminal run:

$ defaults write NSQuitAlwaysKeepsWindows -bool false

The issue goes away after doing the changes to defaults and opening and closing Dashcode twice.

Long Version

There is a bug in Dashcode 3.0.5 that seems to cause project corruption on opening a project. In my case elements of my design disappear. What should look like

opens looking like:

I’ve been an occasional user of Mathematica since version 2.0. While it is a rare and lucky project that has enough math making it necessary to break out Mathematica, when it does happen it is nice to have the Swiss Army Knife of symbolic math and graphics manipulation there in my box of tools.


Spring Tool Suite

My preferred Java IDE is Spring Tool Suite (STS), which is a customized version of Eclipse. STS has good support for all of the Spring libraries, as well as good default support for Maven and Subversion.

X-Plane Simulation and Visualization

Single Integrated Air Picture (SIAP) was the first project I worked on at BA; a great idea to have all participants share information on aircraft location and identification. Our task was testing the SIAP software, and there were some nice simulation tools running on an open source HLA RTI. But there was no visualization, nor were there any accurate complex aircraft models. Airforce guys would come in and ask how do we know if the we can follow an intercept, or how will it look to the AWACS and so on.

Enter X-Plane.

I had looked for a flight sim that supported an external API which X-Plane did. This allowed me to connect X-Plane to the HLA RTI sim and provide completely realistic flight parameters for aircraft like the F-4 and F-15 and F-22, as well as some tankers and sensor platforms.

I could pick a plane and fly the mission and either inject the data live, or record it for playback latter.

Even better I could take generated aircraft data and visualize the flight with X-Plane. Nothing like checking your rotation matrices by watching a plane bank and fly.

Using X-Plane also added the wow factor to some of our demos, and completely stopped the question of our using valid flight models.
