These are some articles (or videos, or podcasts) that I read last year that stayed in my minde afterwards. The most common topic is what everyone is into now. The Reverse Centaur (Cory Doctorow) https://pluralistic.net/2025/09/11/vulgar-thatcherism/#there-is-an-alternative Explains why some have life easier, some have it miserable with the Generative AI revolution. Why ChatGPT Can’t Draw a Full Glass of Wine (Alex O’Connor) https://www.youtube.com/watch?v=160F8F8mXlo There are many articles about this and similar findings.

TL;DR: it was fun to build great graphs. But the battery did not last long, air quality is difficult to track. Above, the box with plywood. Because I do not have a 3d printer, and I like wood. Ingredients For the sensor box ESP 8826, WEMOS D1 LCD 20x16 Humidity sensor DHT11 Air quality sensor MQ9 Red and Green LEDs, corresponding resistors For the outside sensor Old pickes glass jar, and glue or silicon to seal it.

Although neural networks is taking the stage of AI these days, other approaches such as monte carlo methods are still relevant. In some cases, such as Alphago Zero, where a playing agent learns without any prior knowledge, neural network approaches are complemented with monte carlo simulation. When is random random enough? Usually in day to day code, there is a random() function that gives us a single dimenstion random quantity. In some places, to achieve entropy even lava lamps and webcams are used.

Spelling correction is one of the coolest practical challenges in Information Retrieval. Since the famous article from Peter Norvig was published, many implementations were done. This article gave an insight of how practical problems - such simple spelling correction - are solved in Information Retrieval. Here is my contribute, in Erlang. As improvement, the second expansion has to be optimized with some sort of pruning, as words with seven letters can generate more than one million of variations.

Took a while to fix the shellshock vulnerability (did not have the kind of services that makes my host vulnerable). As is ubuntu 12.10, a simple apt-get update does not work: leonardo@pike:~$ x=’() { :;}; echo ? VULNERABLE’ bash -c : VULNERABLE leonardo@pike:~$ wget http://security.ubuntu.com/ubuntu/pool/main/b/bash/bash_4.2-2ubuntu2.5_amd64.deb leonardo@pike:~$ sudo dpkg -i bash_4.2-2ubuntu2.5_amd64.deb leonardo@pike:~$ x=’() { :;}; echo VULNERABLE’ bash -c : leonardo@pike:~$
