Grand Central Dispatch for Android

(Sometimes after a couple of hours of research, the result is a dead-end or needs further digesting.
Still, such a result might itself still be worth remembering.
This is a Quick&Dirty report of one of those cases.)

GCD is an implementation of thread pools / queueing (+ event management (sockets, files), etc) by Apple for Mac OS X / iOS. It was open-sourced, and FreeBSD got an implementation. They are practically an abstraction and simplification over pthreads (+ events, etc), and the GCD implementation includes some kernel and compiler changes (workqueues and blocks, respectively). Implementation details at http://newosxbook.com/articles/GCD.html. It's well performing and seemingly can help simplifying a lot.

What if one wanted to use GCD in Android? Is there anything compatible enough and that could be used at the C level?

Cocinando con citrato sódico casero

Parece ser que un ingrediente típico para la "cocina molecular" de Ferrán Adriá y compañía es el citrato sódico, que se usa por ejemplo para esferificaciones, caviar de frutas y cosas así.

Pero también se usa para algo mucho más simple y usable en casa en el día a día: ¡queso fundido!, que queda genial para salsas, dips, incluso fondues.

¿Pero cuál es el problema? Fundir queso es fácil, ¿no? En realidad, no. Prueba a fundir un taco de 100 gramos de queso normal y verás que el resultado es casi para tirar a la basura: un charco de aceite por un lado, una especie de trapo gomoso por otro. Esto lo podemos salvar con citrato sódico.


GitFlow (and friends) with remotes: avoid the busywork

There are lots of places online where one can learn about GitFlow, but it's seemingly always discussed in a local way; the details, subtle or not, about using GitFlow when you are pushing and pulling your changes through the network are never mentioned.

Now, GitFlow is a bit long on the teeth, and some of the younger and simpler alternatives do take into consideration things as Pull (or Merge) Requests; lately some even want the original GitFlow to be considered harmful. But still, there's a common basic concept in GitFlow and the alternatives, which is local feature branches. How and when exactly to merge them back into a development branch is one of the big differences, but is rarely detailed.

The goal of this post is to gather some tips on how to keep developing in the local feature branch while staying involved on a lively repository; and how to make easier the final feature merging.


Doxygen error parsing in Eclipse CDT

Eclipse (or is it the CDT?) has, by default, some Doxygen integration: if the preferences are set appropriately, Doxygen-style comments are highlighted differently, and Doxygen commands in those comments are further highlighted.

But that's about it. A particular missing feature is that errors in the comments are not highlighted in any way; and that's what made me look for a better alternative.


repo sync --force-sync overwrites your existing repository!

I couldn't find any good explanation of what does Android's repo's --force-sync do, nor why it can be needed. So I'm reporting my painful findings in repo 1.22.
