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. In this second part, I wanna talk about how to extend the same idea to serve a Team of developers. Yes, like the one below. ...

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!); third, implement some Busy Beaver setup and verify that the model works with well known executions. If you want to discover more about Golang, 60’s math games and beavers, go ahead with reading :D! ...

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. Starting from its work and using a FreeBSD installation I did some experiments with jails, to understand better what they really are, how they works - how can you create what it will look like a vintage container - and why you should use them in a FreeBSD environment - at least, to learn something new. ...

Intro Mute post Bye

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. ) And it’s pretty much true, buuuuut… ...

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 $Z$. ...

Introduction First of all…happy new year! I decided after a while to come back online speaking about Golang. In this post, I will focus on parallelism and concurrency and how you can achieve the same behavioral pattern you can achieve with Node.js using await/async statements, without the difficulties (hopefully) of dealing with Single Threaded Event Loop and these primitives (that, btw, keep things really simple). Let’s start! A bit of confusion Concurrency and parallelism are two terms that are bound to come across often when looking into multitasking and are often used interchangeably. However, they mean two distinctly different things. Concurrency is all about the following: ...

Intro As you might know, I use to work with AWS doing and destroying stuff like many other devopssss out there: this post is all about some challenges and problems I had to deal recently - in the last months - and involves some notes about how to deal with multistage environments, decoupling and many other practices you should all know about. The first thing to emphasize is that each of these best practices is fairly clear and well-defined, for sure online (perhaps discussed by bloggers more experienced than me XD) and deeply described in many books. The problem - at least, in my experience - is not about understanding these best practices, sharing them within a team and starting to use them as a group. The huge problem is actually the one of verifying and scaffold a behavioral pattern to put them in place, by definition of standards within a context that did not use them previously. ...

Intro In the last 50 days I had to work a lot for many… many different reasons. The main ones: I was accepted as a Speaker at FullStackConf19 in Turin, talking about coding in mobility. You can find the slide of my speech here and the material I prepared the talk in this Github repo. By the way, I was truly inspired by some of the talks during the conference, and I started brainstorming around the next post; I moved back to Italy and trust me -> it was a pretty complex goal to achieve, with particular regards to my car; I joined Enerbrain and I’m really having fun with theme building smart-energy solution as a Devops Engineer; I joined a softball team - yes, it’s mixed, but it’s officially played also by men hahe. Let me say that it’s not the usual kind of team, it’s more a sort of “group of old friends playing drinking and…” overall having fun together; What else… oh yes, I migrated my blog to Hugo and I also migrated my release pipeline to Gitlab. ...
