A friend of mine just reported me a very tragic event. His bag with his laptop and his backups hard drive was stolen. I can feel his pain, having experienced the very same situation once, and I am writing here hints for him and the rest of the world to protect yourself from this eventuality.

I am writing this post from my iPod touch. I am not enthusiast at all of the device, and I would gladly return it, but I am in a “no choice” situation. The reasons for my disappointment are the all-well-known limitations of the device, in particular the limit to only [...]

I wanted to use Grok for my future development, so I just spent a week trying to do porting of a project from Django to Grok. I had to back off.
Grok is very powerful without doubt. However, the learning curve is steep, and I am not talking about “mountain trekking” steep, I’m talking about “walking [...]

I just installed Snow Leopard, MacOSX 10.6, on my laptop.
It is indeed much faster. Considerably faster. I don’t have actual measures, but you can appreciate it. The interface is much snappier in response. There are many tiny improvements around, minor things, nothing revolutionary, although I really appreciate the new Expose’: now you can recall specific [...]
You are welcome to take a look at Part 1 and Part2 of this series.
In this third part of the “silicon-based” bacterial evolution, we move to the real action. I developed a program (you can download it from here), which perform evolutive selection based on mathematical criteria. The program has a set of rules to [...]
Suppose you have a MySQL table containing an enum column. The enumeration allows the values “FOO”, “BAR” and “BAZ”. This is a production database, hooked up by a quite huge amount of programs inserting and deleting rows into that table.
Now suppose that, for some reason, one of these programs tries to insert the value “HELLO” [...]
I just released Chestnut 2.2.0. Just grab it while it’s hot!
I had the chance to see the google wave presentation
I was in awe with the power of this old, new thingie. As soon as wave is released to third parties, email will be a thing of the past in less than three years. Start counting, I can bet on it.
This is the second part of a post relative to evolution. You can find the first part of the post here.
The last argument in the first post was relative to the requirements for evolution to happen. To recall, you need
An imperfect replicator, an entity able to produce a copy of itself, for example the DNA [...]
This post is in different parts. The fact is that it requires quite a lot of time investment, something I really don’t have in this period.
A long time ago I wanted to play with the concept of genetic code, and how it represents nothing but a language to code for molecular machines. As the Jacquard [...]
