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 :) Everyone use Docker and normally when something is so diffused, there’s always someone else that try to figure out how to leverage the diffusion to do bad things (you know what happened in Breaking Bad). Only a few months ago it happened that someone pushed some malicious software - cryptomining - over lot of images: this happened because, despite the fact that everyone use Docker, not so many people are really aware about security over Docker....

Prelude Today I’m gonna talk about how you can leverage Traefik2, k3s, Cloudflare, and RaspberryPI to get the best out of your…apartment. After the image, I’ll go through the setup of everything needed! Why Traefik2 For those of you who never heard the word Traefik before, here it is: Traefik is an open-source Edge Router that makes publishing your services seamless. I already made some experiments in the past (look at my two-pieces series I run VSC in the browser and I am just fine - Part I and My team run VSC in the browser and they are just fine - Part II) and I’ve always been fascinated by the way Traefik just works....

Introduction As you might know, at the re:Invent AWS recently announced the capabilities of running Lambda by getting the code directly from a docker image you provide, as illustrated here. Moreover, they also announced the Amazon ECR Public and Amazon ECR Public Gallery that you can reach at https://gallery.ecr.aws/. And this was pretty much my reaction: What you might need to know before begin First of all: keep calm, because there’s already a Github Repo to build an entire fleet of microservices - with their respective ECR-based repository - with only one command from the shell....

Prelude Hi guys, after a series of back-to-the-future-I-didn’t-have-time-to-write-new-things… I’m back. What happened in the last months… ok, covid19 put the whole world in trouble, I bought an apartment, I opened a company and I resign my contract. Really. Nothing. Special. But TODAY - I wanna talk about a project I have since a while, and I worked on a boring Sunday afternoon: I hacked my blog to let Polly read it for you!...

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....
