Probabilistic processor and the end of locks

Every now and then, when I’m bored with normal work, I tend to my personal projects. For some reason, that tends to be mid-year, every year. So, here we go… Old ideas, new style This time was an old time project, to break the parallelization barrier without the use of locks. I knew simple boolean […]

What I don’t miss about Java

Disclaimer: This is not a rant I spent my last year working with Java, and it was not at all bad. But while Java has its moments and shines, I always felt a bit out of place when using it. In fact, when I moved back to C++, contrary to when I moved to Java, […]

Humble Bundle

I’m not the one to normally do reviews or ads, but this is one well worth doing. Humble bundle is an initiative hosted by Wolfire studio, in which five other studios (2D Boy, Bit Blot, Cryptic Sea, Frictional Games and the recently joined Amanita Design) joined their award-winning indie games into a bundle with two […]

Barrelfish

Minix seems to be inspiring more operating systems nowadays. Microsoft Research is investing on a micro-kernel (they call it multi-kernel, as there are slight differences) called Barrelfish. Despite being Microsoft, it’s BSD licensed. The mailing list looks pretty empty, the last snapshot is half a year ago and I couldn’t find an svn repository, but […]

Smart Grid Privacy

I have recently joined the IETF Smart Grid group to see what people were talking about it and to put away my fears on security and privacy. What I saw was a bunch of experts discussing the plethora of standards that could be applied (very important) but few people seemed too interested in the privacy […]

Linux is whatever you want it to be

Normally the Linux Magazine has great articles. Impartial, informative and highly technical. Unfortunately, not always. In a recent article, some perfectionist zealot stated that Ubuntu makes Linux looks bad. I couldn’t disagree more. Ubuntu is a fast-paced, fast-adapted Linux. I was one of the early adopters and I have to say that most of the […]

Gtk example

Gtk, the graphical interface behind Gnome, is very simple to use. It doesn’t have an all-in-one IDE such as KDevelop, which is very powerful and complete, but it features a simple and functional interface designer called Glade. Once you have the widgets and signals done, filling the blanks is easy. As an example, I wrote […]

SLC 0.2.0

My pet compiler is now sufficiently stable for me to advertise it as a product. It should deal well with the most common cases if you follow the syntax, as there are some tests to assure minimum functionality. The language is very simple, called “State Language“. This language has only global variables and static states. […]

The LLVM compilation infrastructure

I’ve been playing with LLVM (Low-Level Virtual Machine) lately and have produced a simple compiler for a simple language. The LLVM compilation infrastructure (much more than a simple compiler or virtual machine), is a collection of libraries, methods and programs that allows one to create a simple, robust and very powerful compilers, virtual machines and […]

40 years and full of steam

Unix is turning 40 and BBC folks wrote a small article about it. What a joy to remember when I started using Unix (AIX on an IBM machine) around 1994 and was overwhelmed by it. By that time, the only Unix that ran well on a PC was SCO and that was a fortune, but […]
