If you think you’re a regex person (not following what XKCD has told us), and that most problems can be solved with simple (yet always too simple) regular expressions, I’ve got a challenge for you: http://regex.alf.nu/. I know a bit of regexes (use them quite a lot with VI’s search, but it’s not ECMAscript), and…

Hello there! After a short break, I’m finally getting back on track! This last month has been quite a ride, so many new experiences and, while not busy busy busy, been lazy lazy lazy. 🙂 Truth is, I’ve been resting or running errands when not working, and the little time I had at home I…

Hello there! Tonight I’m going to talk about a new app that I’ve found, reading on some blog around the interwebs… quite a generic sentence. It is a really nice and useful app called “utter!”. It claims to be a voice assistant app, but more useful than the iOS’s Siri, which is quite a claim!…

Hey there again. Well, the new project is going OK, but… while the first week was great, the second came with a surprise bomb, and now we’re trying desperately hard to beat a tight deadline for an out-of-mind scope. At least I’m learning more Java than I thought I would. No clue that this post…

Hello there! I’ve probably mentioned earlier that I’ve got two cheap tablets, and I got to root one of them. At least I was able to update it to 2.3 (I guess, don’t remember) with the Uberdroid distro image. Well, the other one has a RockChip chipset, and that’s quite harder to do, since z4root…

Hey there! I’ve committed a new class on JenPop, and it’s called “Individual”. It was made to represent the rules of typical genetic algorithms: a genetic representation of the solution domain; a fitness function to evaluate the solution domain. I’ve read a bit more on the subject and figured that genetic algorithms, although being able to achieve good solutions…

So, at last, I’ve joined the new project team, reading documentation and “first steps” to develop the new application. They seemed pretty organized so far, and I was able to solve all the hickups I’ve had when starting to install the development environment. Since I started by the end of tthe day, I didn’t have…

Today, at Datacom, we’re celebrating the conclusion of the development of two projects, our little and versatile “CPEs” (both are different models of G.SHDSL bridge modems with Ethernet and PWE3 interfaces). It has been a brief (for me, at least) but intense experience, I’ve learned a lot. Next week I’ll most likely be joining a…

Hello again! This one is one hell of a tricky problem. No wonder it’s called “Numbers”: In this problem, you have to find the last three digits before the decimal point for the number (3 + √5)n. For example, when n = 5, (3 + √5)5 = 3935.73982… The answer is 935. For n = 2, (3 + √5)2 = 27.4164079……

Hello there! While still trying to find a good way to solve the 2008 Round-1A-C problem, Numbers, I came across something that I still have to adventure a bit on: Floating Point number precision. I mean, is there a way (even at expense of time, CPU and memory usage) to fully reproduce what calculations “by…
