10 things software developers should learn about learning
As software developers, we understand the detailed workings of the different components of our computer systems. And–probably due to how computers were presented since their appearance as “digital brains” in the 1940s–we sometimes believe we can transpose that knowledge to how our biological brains work, be it as learners or as problem solvers. This article aims at making the reader understand several mechanisms related to how learning and problem solving actually work in our brains. It focuses on helping expert developers convey knowledge to new learners, as well as learners who need to get up to speed and “start coding.”...

Heads up! A miniDebConf is approaching in Santa Fe, Argentina
I realize it’s a bit late to start publicly organizing this, but… better late than never 😉 I’m happy some Debian people I have directly contacted have already expressed interest. So, lets make this public! For all interested people who are reasonably close to central Argentina, or can be persuaded to come here in a month’s time… You are all welcome! It seems I managed to convince my good friend Martín Bayo (some Debian people will remember him, as he was present in DebConf19 in Curitiba, Brazil) to get some facilities for us to have a nice Debian get-together in...

Ruffle helps bring back my family history
Probably a trait of my family’s origins as migrants from East Europe, probably part of the collective trauma of jews throughout the world… or probably because that’s just who I turned out to be, I hold in high regard the preservation of memory of my family’s photos, movies and such items. And it’s a trait shared by many people in my familiar group. Shortly after my grandmother died 24 years ago, my mother did a large, loving work of digitalization and restoration of my grandparent’s photos. Sadly, the higher resolution copies of said photos is lost… but she took the...

A deep learning technique for intrusion detection system using a recurrent neural networks based framework
So let’s assume you already know and understand that artificial intelligence’s main building blocks are perceptrons, that is, mathematical models of neurons. And you know that, while a single perceptron is too limited to get “interesting” information from, very interesting structures–neural networks–can be built with them. You also understand that neural networks can be “trained” with large datasets, and you can get them to become quite efficient and accurate classifiers for data comparable to your dataset. Finally, you are interested in applying this knowledge to defensive network security, particularly in choosing the right recurrent neural network (RNN) framework to create...

Pushing some reviews this way
Over roughly the last year and a half I have been participating as a reviewer in ACM’s Computing Reviews, and have even been honored as a Featured Reviewer. Given I have long enjoyed reading friends’ reviews of their reading material (particularly, hats off to the very active Russ Allbery, who both beats all of my frequency expectations (I could never sustain the rythm he reads to!) and holds documented records for his >20 years as a book reader, with far more clarity and readability than I can aim for!), I decided to explicitly share my reviews via this blog, as...

The stuff games are made of
What do we consider the “stuff” that makes up a video game? Is it interesting gameplay? Compelling graphics? Lifelike effects and fast-paced first-person shooter (FPS)? Deep strategy? Engaging mechanics that don’t let you go, that glue you to your favorite gaming device? How simple can a game be without losing its essence as a game? Pippin Barr, in a short and easy-to-read text, approaches these questions in a very novel way, and brings surprising and fresh answers. The book begins by setting up the narrative of a weird, minimalist video game where the object of the game is to manipulate...

There once was a miniDebConf in Uruguay...
Meeting Debian people for having a good time together, for some good hacking, for learning, for teaching… Is always fun and welcome. It brings energy, life and joy. And this year, due to the six-months-long relocation my family and me decided to have to Argentina, I was unable to attend the real deal, DebConf23 at India. And while I know DebConf is an experience like no other, this year I took part in two miniDebConfs. One I have already shared in this same blog: I was in MiniDebConf Tamil Nadu in India, followed by some days of pre-DebConf preparation and...

Humble AI
While readers of Computing Reviews are more aware than the general population when it comes to whether artificial intelligence (AI) is a magical panacea or the probability of a general intelligence that will develop thinking capabilities and make decisions on its own, we are actually aware of AI’s greatest strengths: finding patterns, probably hidden to the naked eye, and arriving at inferences based on said patterns. That ability has made AI-based systems a tool of choice to make statistical predictions and estimations, learning from enormous datasets, about human behavior. AI tools are often applied to risk assessment for financial operations....

Debian@30 — Found the shirt I was looking for last month
Almost a month ago, I went to my always loved Rancho Electrónico to celebrate the 30th anniversary of the Debian project. Hats off to Jathan for all the work he put into this! I was there for close to 3hr, and be it following up an install, doing a talk, or whatever — he was doing it. But anyway, I only managed to attend with one of my (great, beautiful and always loved) generic Debian or DebConf T-shirts. Today, when going through a box of old T-shirts, I found the shirt I was looking for to bring to the occasion....

A free press, if you can keep it: What natural language processing reveals about freedom of the press in Hong Kong
The British colony of Hong Kong was ceded back to Chinese sovereignty in 1997, after 150 years of occupation, under the “two systems, one country” principle. Given the Chinese is widely known in the West for its tight grip on its press, this short book takes as a goal to use computational analysis in the field of natural language processing to assess changes in press freedom over the 25 years of Chinese rule over Hong Kong. The author states that, by doing a mixed-methods comparison of news published about the various Hong Kong protest movements that have surfaced since mainland...
