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....
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....
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....
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....
A little tool for a small city Here we are!! I recently moved to Germany to join the adidas - platform engineering team. This is a really small piece of GOde (:P) I wrote for Erlangen (my new place) citizens ^^ Needs You will only need an https://www.internationalshowtimes.com/ movie api key. You can get one quite easily by going here Scope You would simply like to be informed about new OV movies on air in cinemas from your shell…here we go!...
Introduction I recently started interesting about the concept of streaming - not videos, of course - mainly because in the last months I collected several sources to be used as starting point: so, waiting for my Google Home Mini to be shipped, I decided to mix togheter two words I often see surfing the Web. The first is Kafka - that is a distributed streaming platform (ok but what exactly does that mean - for real?...
Introduction I recently build a Slack command to help me handle actions on my VPC. The only thing you need is an AWS account - Free Tier it’s ok. I recently wrote about how to maximize resources, with particular focus on the number of hours you have in Free Tier - using specific CloudWatch Rules. In this article, I want to describe how I extended my architecture to invoke actions - potentially, all the action provided by Amazon Web Services official SDK(s) - with a single Slack command....
Introduction If you have an AWS account in Free Tier, bla bla bla ok stop: I am a AWS Lambda maniac. I only wrote about them (here, here). In this article, I want to talk about my new purchase that is - of course - related to AWS Lambda: the AWS IoT Button. It first made its appearance on the IoT scene in October of 2015 at AWS re:Invent with the introduction of the AWS IoT service....
Introduction If you have an AWS account in Free Tier, you have (updated: March, 13th 2018) 750 hours/month to run EC2 (small ones) in your VPC. You also have a lot of other resources, such as AWS Lambda functions (I wrote about them here and here) and CloudWatch Events. In this article, I talk about smart resources handling and some trick - actually, not so smart XD - I setup to take the best from the services....
Introduction Recently I worked with AWS Lambda and API Gateway to extend my set of personal APIs and collect information from several sources. I wrote an article on that (if you want to have a look). In this article I will talk about the AWS Step Functions service that enable create finite states machines to easy coordinate the components of distributed applications and microservices using visual workflows. Why AWS Step Functions?...
