May 5, 2013 - Tabata Trainer - Android App

Comments

Today I released my first Android application, Tabata Trainer.
Developing this app has made learning Android development a very pleasant experience, while at the same time adding something new to the mobile ecosystem.

This app aims at providing a way for Tabata practitioners and general sports fans to do their exercises in an appropriate and automated timely manner. It also provides the ability for users to define/plan their own training exercises and times. More features are planned for next releases!

Tabata is a form of high-intensity interval training (HIIT) based on a study by Izumi Tabata. It initially consisted of one exercise carried out intensively during 20 seconds with 10 seconds of rest after it. This exercise was looped 8 times, giving a total of 4 minutes.

Summary of features:
  • Tabata timer;
  • Start/pause/stop controls;
  • Definition of rest and exercise time;
  • Definition of the number of rounds;
  • Definition of any number of exercises, with textual descriptions, that form a custom training/workout;
  • Text-to-speech engine to read exercises' names to guide users throughout their workouts;
  • Sound alerts: Resting; Exercising; Darth Vader breath stimulator; Workout completed;
  • English (UK) and Portuguese (Portugal) text languages supported;

      Apr 24, 2013 - Intel graphics extreme color saturation using HDMI and M2250D

      Comments

      When I acquired the LG M2250D display I noticed that when connecting it to my computer via HDMI, under Windows, the colors would be extremely saturated. This issue was not reproduceable in other operating systems and also not via VGA (under Windows too).

      Saturated color of Windows' window
      Expected color of Windows' window

      My display (when via HDMI) is detected and assumed by the Intel graphics driver as a "Digital Television" instead of a "Monitor". I think that is because it is a hybrid monitor and TV. The consequence of this is that the driver will adjust the color scheme to match a TV watching scenario (and won't let us change it in a straightforward way!).

      What I did to fix (workaround) this was open up "Intel(R) Graphics and Media Control Panel" (one way can be by pressing Ctrl+Alt+F12) and change a few settings. Here's how you can do it:

      First:
      Select "Advanced Mode" in the dropdown that, by default, is set to "Basic Mode". Then select "Custom Resolutions" inside "Display".

      Changing to Advanced Mode
      Second:
      Fill the "Add Custom Resolution" fields with the intended screen resolution and under "Timing Standard" select "CVT-RB" (this is where the secret lies).

      Changing Timing Standard for specific resolution
      Finally:
      If your screen doesn't flicker automatically, you may need to restart your computer. You need to add a custom resolution configuration for every different resolution you may need. The "Timing Standard" can be different from "CVT-RB", but that one I can assure works.

      How it should look after everything
