OOP is the your new legacy
Today I took a light rail with my son, to bring him to school. That tram is 90 years old. It has been maintained for 90 years. Milan city sold some of them to San Francisco too.

Il saggio progetto svedese, rinato: Elixir e Phoenix
Negli ultimi 20 anni sono successe tante cose imprevedibili. Nel 1995 nasce Java. Nello stesso periodo nasce Erlang. Java inizialmente segue la strada culturale tracciata da Sun, e si configura come un linguaggio estremamente verboso, con API specifiche per la gestione della concorrenza (es keyword synchronized per gestire nativamente le zone critiche che necessitano di …

Property Based Testing Tool
Tonight I stubled upon PropEr, a Property based testing tool for Erlang. It seems a very smart idea: instead of writing a single unit test, you write a set of properties your code must satisfy. From the site: A property-based testing tool, when supplied with this information, should randomly produce progressively more complex valid inputs, …
Recuperare Erlang
Erlang è un linguaggio a mio avviso sottostimato, che ha parecchie cose da insegnare ai vari Scala/Rust/Java(Script) out of there… In particolare ci sono un insieme di feature di Erlang che prese singolarmente non sono difficili da comprendere e implementare, ma è l’insieme delle idee fondanti di Erlang che lo rende assai diverso dagli altri. …
Erlang: a lesson to learn…again!
Erlang is a great language. [2019-UPDATE] Erlang 22 is OUT, so I wanna to come to the party! On April 2015, Erlang father’s Joe Armstrong give us a very interesting lesson I want to tell about. There was a long thread titled “Erlang and Akka, The Sequel” on the erlang mailing list, reasoning about the need …
Rebar poor proxy git fixer
Sometimes you are behind a http proxy, and the git:// protocol is not accessible. For instance on erlang rebar, all developers prefer the git:// protocol when listing dependency. But how to fix it if you are behind a http proxy? Ask help to git… [bash] git config –global url.https://github.com/.insteadOf git://github.com/ [/bash] Credits: http://erlang.org/pipermail/erlang-questions/2014-March/078402.html
Er Zauker v0.0.5: Let it go
Let it go, let it go! Can’t hold it back any more. Let it go, let it go! Turn away and slam the door. … Let it go, let it go. I am one with the wind and sky. Let it go, let it go. You’ll never see me cry. (by Demi Lovato, “Frozen”) I …
ErZauker Revenge!
After a bunch of time, I take back my Erlang Hammer from the sand of time. The result is ErZauker v0.0.2 the first pure-Erlang implementation of a code indexer. Er Zauker is a tiny but speedy search engine tailoring code searches. Zauker is backed by REDIS, the fastest RAM-based NoSQL engine you have never seen. The code get …
Erlang Power Links
Ready to study the Erlang? Take a look to http://howistart.org/posts/erlang/1 for understanding how erlang releases works (and how to deal with them). Erlang Maps are the next big thing and this article from Joe Amstong introduce you to them. For some lengthly tutorial take a look to this http://learnyousomeerlang.com/maps And Finally Lisp Flavored Erlang and Ruby Flavored Erlang.
Intervista a Francesco Cesarini di Erlang Solutions
A language that doesn’t affect the way you think about programming, is not worth knowing. Yale Professor Alan Perlis In occasione dell’Elixir Conf siamo lieti di pubblicare una intervista con Francesco Cesarini. Nel 2009 abbiamo già recensito “Erlang Programming A Concurrent Approach to Software Development” scritto a quattro mani con Simon Thompson. Ora siamo lieti di ospitare una intervista ad …

Erlang vs Ruby: Er Zauker
Negli ultimi mesi ho sviluppato un motore di ricerca per il codice, chiamato code zauker. Lo ho scritto in Ruby e Redis. Ruby è un linguagio che conosco da tempo, ma housato molto poco. In questeultime settimane ho voluto riprendere in mano Erlang, e per esercizio ho provato a riscrivere il kernel del motore di indicizzazione …
Functional Programming
Because of the success of my article on java closure, I have decided to write another article on functional programming. In the last year functional programming is waving back to us, for a lot of reason. Let’s summarize the facts: Functional programming is based on the core concept of pure function. The main advantages of …
Python functional programming
This article is a work in progress: it will be expanded by your comments… Python is a very curios programming languages: it give you classes but also a strong function-oriented environment to play with. So, if you like functional programming (read: you like Lisp and/or Erlang) you should give python a closer look.
Erlang Book Review
After reading an interesting article on Erlang and Java interoperability, I have decided to dedicate my spare time to Erlang. O’Reilly has just published a wonderful book on Erlang, so I decided to dive into it.
