New blog platform

It is official, this blog is now hosted at Besides the change of domain, the platform has also been migrated from Blogger to Jekyll, hosted in GitHub Pages. This decision will allow me to maintain the pages with more ease and flexibility, leveraging most of the benefits of using git.

The main reason for creating it is to provide additional troubleshooting support for Wrkout users, who may be having issues with the speech feature present in the app.

Loading app/web page from Android intent when app is disabled

In Android, it's pretty easy to load a page from Facebook or Twitter or a similar one, from our very own app. By passing an intent with the request, the related app will automatically show up with the desired content. If the app is not installed we can detect that scenario so that, for instance, the browser starts up and loads the link for the wanted page. With Google+  it's even simpler, as we just need to pass the web URL. Android then selects if it should use the Google+ app or a browser (taking into account users' preferences).

However, what if the app is installed but has been disabled (for example through App Quarantine)?

GNS3 Cisco IOS Escape Sequence

If you want to use the escape sequence in IOS in order to cancel pending commands (like a ping or a traceroute), using GNS3, and you're trying to use Ctrl+Shift+6 or Ctrl+C or any other combination that is supposed to work, as far as you can tell from the web, then just try Ctrl+6, it will probably work.

Rooting Memup SlidePad NG 808DC

After noticing there were no known methods of rooting the tablet Memup SlidePad NG 808DC (the methods for the other models did not work with this one), I took some hours off in the past 20th of July to check how hard it could be. It seems it's actually pretty easy and, finally, I'm going to post my method. Although the first root method on the web specific for this tablet, it may work for similar devices as well, but that's on your own responsibility.
