The Doomsday rule This is a repost of an old article :) A few months ago I came across the name of J. H. Conway: you’re wondering who the hell he is. Well, Conway is an English mathematician active in the theory of finite groups, knot theory, number theory, combinatorial game theory and coding theory. He has also contributed to many branches of recreational mathematics and he is the invention of the Game of Life....
Introduction Function composition is something we as developers do every day, more or less. This concept come from Mathematics: if you search on Wikipedia, you find out that function composition is an operation that takes two functions \(f\) and \(g\) and produces a function \(h\) such that \(h(x) = g(f(x))\). In this operation, the function \(g\) is applied to the result of applying the function \(f\) to the input \(x\). That is, the functions \(f: X \rightarrow Y\) and \(g: Y \rightarrow Z\) are composed to yield a function that maps \(x\) in \(X\) to \(g(f(x))\) in \(Z\)....
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....
Intro If you work with AWS, you might be involved in building infrastructure to enable some of your customers (both internal and external) to use a particular service, or just to try one of the hundreds open-source application available on Github. Furthermore, most of the ML/AI tools are shipped in docker containers and the philosophy -> if it runs on docker, it runs everywhere has been spread up to the highest level of management (nice, but… sometimes dangerous 😅 ed....
Introduction This is a repost of an old article :) In the first part of this series - I run VSC in the browser and I was just fine - I wrote many stupid things around the possibility of having a VSC server instance running inside AWS over a simple, immutable, ec2 instance. The template {that can be easily deployed by a Lambda function [that can be easily deployed behind a route53 record (that can be easily placed as the endpoint of a custom Slack action)]} let you start your IDE and code from wherever you would like to....
Introduction This is a repost of an old article - that actually also inspired my talk of the last year at FullStackConf2019 :) Serverless and managed things are the best choices if you don’t want to deal with infrastructure (3 2 1: fight) buuuuut…even immutable things are not so bad for this purpose - at least, if they are immutable for real 🤣 Today I wanna talk about a useful way to run an instance(s) of VSC server in AWS and code from everywhere (yes, even your iPad): let’s start!...
Preamble This is a repost of an old article :) 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 Recently I became nostalgic and fascinated with stuff from the past, so I decided to create a Vagrantfile to work with FreeBSD1. Why FreeBSD? Because as a developer, I really like Docker and I started looking in the past to find its historical birth: in fact, as a concept, Docker is no so recent as you think, and I think it exists also because of the works of some other bigs from 80’, such as Poul-Henning Kamp2....
