Much more than a post (again) What is the quantum theory? As said by quantumexperience official site by IBM, it’s an elegant mathematical theory able to explain the counterintuitive behavior of subatomic particles, most notably the phenomenon of entanglement. In the late twentieth century it was discovered that quantum theory applies not only to atoms and molecules, but to bits and logic operations in a computer. This realization has been bringing about a revolution in the science and technology of information processing: I decided to write some notes to better explain, from a physics-agnostic computer scientist’s point of view XD, what I understood - and it is certainly wrong - about Q until now and why I think it’s an amazing field for computer science....

Preamble In 1962, Hungarian mathematician Tibor Radó introduced the Busy Beaver competition for Turing machines: in a class of machines, find one which halts after the greatest number of steps when started on the empty input. Even if it could seem trivial, the Busy Beaver competition has implications in computability theory, the halting problem, and complexity theory. I decided to use GoLang to implement a Turing machine library and accomplish three goals: first, having a Turing Machine model to play with for learning purpose; second, learning how to use interfaces and the factory pattern, other then testing package to test my code and let it be more flexible for future enhancement (at least I hope!...

Preamble I recently bought 4 small smart bulbs - the latest one you most probably decide to buy for your smart home 😂😂 I think it’s useless talk about what you can do: I will only focus on the important things. They DON’T need an hub; They support Alexa; They support Google Assistant; They support IFTTT; There is an app, called Smart Life (iOS, Android) But most important you can build your small SPA in your bathroom....

Preamble I would like to say “recently”, but actually is almost a few years I heard - and I’m still hearing a lot about Machine Learning and I didn’t want to believe it until now - believe me, I truly didn’t want to believe it - but yes here we are Machine Learning ufficially replace Big Data as buzzy word of the this past years, most problably will be still the word of the next year and I could not be more sad, frustrated, and worried about....

Introduction Predicting the next item of a sequence over a finite alphabet has important applications in many domains. Since I always wanted to implemented something like that, while I was looking for an interesting approach I found this interesting idea based on tree. And you don’t deal with trees since a lot, be prepared because as usual it seams simple, but it not. Moreover, since I like Golang and I always wanted to try UniK, I decided to implement my version of the CPT using Golang and use this exercise as a source to build my first unikernel image....

Prelude Disclaimer this post contains references to real problems, addressed in a disuruptive and totally not informed way. Lot of employees were mistreated to have enough material to write this post. What you will read is played by professionals: dont’t try this in your Company. The truth about companies Today every company in this beautifull world suffers the same problem: the migration problem. Yes, I know you got it and you’re kind of thinking “what the fuck?...

Introduction This is actually a sort of back-to-the-future post because it’s related to something I completed one year ago: I built this Elman network and it learnt to count. What I shame, I forgot it, now it’s kind of its first birthday so let’s celebrate :D This is Elman, the best in class in adding int32 numbers. For everybody who already knows what I will talk about (what?!), here’s the Github repo....

Introduction In my previous post I wrote about the cognitive architecture ACT-R, mainly putting together what I learnt by research over the topic. In this post, I would like to go more in depth about how ACT-R works, the concepts behind and try to provide my interpretation of some technical examples, regarding coding of the modeling and everything related. What really is ACT-R ACT-R is a production system theory that tries to explain human cognition by developing a model of the knowledge structures that underlie cognition....

Introduction I’ve always been fascinated about cognitive systems and all the theories about them. Unfortunately, I never had the chance to actively work on a cognitive architecture: making experiments over these technologies is difficult because it’s difficult to me even only think about some possible toyproblem to solve. So this article is more about the basics, or at least what I found interesting about the topic. ACT-R One of the most famous cognitive architecture is ACT-R: ACT-R a....

Prelude As far as I know there are many ways to create today in IT. What is becoming more difficult is doing it properly and taking the right decisions but (spoiler)… But… I’m starting feeling that my repository is on the right direction to be self.deployable and agnostic. Above the infrastructure, which is provisioned by terragrunt and terraform, one or more actor(s) is placed (i.e. Jenkins, but whoever it is), the actors will be redeployed, the pipelines restored and they will start redeploy applications (even pieces of infrastructure with dependencies) on their behalf to the various parts of the infrastructure....
