Raspberry Pi was one of those projects that were “godsent” (just like Arduido). A cheap and very small computer that would let the little ones and also older folks learn, explore, prototype and build lots of things that previously would be inaccessible to many. So in this post I want to give you some tips […]
There, I said it … and a lot of other people said it before me (here, here, here, here, … and the list goes on and on). Before I proceed with my argument, I would like to say that, slack is great product (even if the client consumes lots of memory) and works very well […]
