Coding

Merry Christmas by nerds Here we are!! Christmas holidays are coming and it’s time to collect nerd greetings for nerd friends! In this article I have collected some of my favorites: starting from css to the most unhealthy c code in the world, I hope you enjoy these repositories / snippets / gist / sketch! Best wishes for happy holidays! CSS While I was looking for some cool css stuff to share with you, I found this fantastic gist that show the kind of magic a web expert can do with a bunch of css lines. Riddle: what do you see if you use IE as a browser? The answer after the preview! ...

The Doomsday rule 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. Ah, I was forgetting one last thing: he is currently Professor Emeritus of Mathematics at Princeton University in New Jersey1. Ok. let’s respect this guy but…what would I talk to you about? Well, in this article I will talk about a magic trick: the Doomsday rule. ...

Predix Machine and how to configure them In September, waiting for a contract proposal from the company where I currently work, I wrote a tool for the (more or less) automatic configuration of Predix© Machine. Predix©1 is the platform created by GE for Industry 4.0, powered by CloudFoundry2, to securely connect machines, data, and analytics to improve operational efficiency, help you develop, deploy, and operate industrial apps at the edge and in the cloud. As part of my internship I worked with the predix machine and I shared my work to the GE platform. GE mantains an open repository with predix tool ...

History We can date the birth of artificial neural networks in 1958, with the introduction of Perceptron 1 by Frank Rosenblatt. It was the first algorithm created to reproduce the biological neuron. Conceptually, the easier perceptron that you might think of is made of a single neuron: when it’s exposed to a stimulus, it provides a binary response, just as would a biological neuron. This model differs greatly from the neural network involving billions of neurons in a biological brain. Shortly after his birth, the researchers showed the world the problems of Perceptron: in fact, it was quickly proved that perceptrons could not be trained to recognize many classes of input patterns. To get a more powerful network, it was necessary to take advantage of multiple level of units and create a multilayers perceptron, with more intermediates neurons used to solve linearly separable2 subproblems, whose outputs were combined together by the final level to provide a concrete response to original input problem. Even though the Perceptron was just a simple but severely limited binary classifier, it introduced a great innovation: the idea to simulate the basic computational unit of a complex biological system that exists in nature. ...

Recipe for a good meal A few months ago I started working with Golang to a proof-of-concept project using the amazing goa package (thank you atosatto for your advise): I omit the praise, I would only say that - imho - Golang it’s a very funny language to use for many reasons (stay tuned, I will write about Golang and my favourite packages). However, in this post I want to share a little piece of my experience about this project: the main ingredients for this recipe are Golang (in particular the goa package) and Docker - with some piece of Angular 4, nginx, and minor stuff. I excluded the storage part so the two elements of the boilerplate I will talk about live in separate container - you can of course orchestrate with k8… ok, whatever you want :P ...

Why Java why now I recently followed a course1 on YouTube by Adib Saikali (NewCircle Instructor) about the key features introduced in Java > 8: it’s an old post regarding old stuff but…I collected some notes (mainly because I need to write down what I’m listening to to stay focused and learn new concepts) that I decided to share with you. This is to say, this post is for every one that had put aside Java for a while and is now looking for a quick overview of the key aspects - exactly like me some weeks ago - to improve his abilities in coding, taking advantage of the old (n.d.r.) features introduced a few years ago. For thus who missed the footnote before and want to jump directly to the lesson, here you can find the main source of the content of the next paragraphs. ...

The problems of life Each of us has dreams, aspirations, hobbies, interests, but also hundreds of deadlines, a thousand commitments, ten thousand thoughts, a hundred thousand different problems to cope with every day. I am a computer scientist and personally all these things in my life translate into a huge pile of [things/books/articles/guide/blogs] to read, which by the way are very often interrelated. The situation is more or less this: ...
