Three different ways to connect two Go services with gRPC

I couldn’t find a single article explaining the different ways of connecting two Go applications using gRPC. After many tries, I came to the final 3 most useful ways to go: Basic connection, no security First, and easiest, is to not use TLS at all and not require any certificate. This mode is most useful […]

Bye bye vim powerline, hello airline

[edit: You can find a really nice summary of airline on vimawesome] It is quite a pain to have some nice status line with vim. For this, until now, I was using the powerline module, that was cool, but has major drawbacks.

Fail2ban Configuration for NGINX anomalies

Fail2ban is a really cool log analyzer (mostly) that can block ips using several different methods (iptables, ipfw, ip route blackhole, etc.). The problem is that you have to define filters (regexes in fact) that will trigger the ban for each service, because each one has a different way to report anomalies. There are not […]

New version of chess PGN to TeX to PDF converter

OK, I’m shameful. After fighting with Scid’s exporter, and then correcting bugs in pgn2ltx’s source, I finally decided to take a look at that PGN file format. And guess what? It’s already composed of FEN notation. And guess what? that super-über cool new skaknew module for LaTeX gets its input as FEN!!

Updated mate-in-one document, now includes chess coordinates

Update: A new updated version of the PDF is available, which includes which side to play. After a request to have coordinates on the board, to be able to write answers (a really nice idea, especially that Ido begins writing), I noticed I couldn’t do it so easily, because the LaTeX module (chess12) didn’t support […]

Auto-provisioning with Asterisk and ST2030 Technicolor/Thomson phones

An introduction to the ST2030 The ST2030 is one of the few SIP phones distributed by Thomson (now changed name to Technicolor). In fact there are only 2 models: the ST2020, and the ST2030, and also a new one, the TB30, which is the successor to the ST2030. The ST2030 is supposed to have an […]

How to make the simplest unittests in Python

Testing your code is nearly a requirement (even more so in Ruby). Unittests are now the most vital elements for evaluating the quality/viability of a project. I was a little jealous of Ruby where you don’t have so much to write to implement unittests. Here is a simple example: require “mymodule” require “test/unit” class TestMyModule […]

Default behaviour in implementation of STOMP protocol in RabbitMQ with python

Why STOMP? Why STOMP, and not directly AMQP, as I’m using RabbitMQ. No real reason, but the fact that there are less dependencies on a STOMP client, as it’s just a socket with text sent. Implementations There are several implementations of the STOMP protocol for Python. The module I chose is python-stomp (version 0.2.9), from […]

Asterisk: DADHI module not working when using Xen

If you want to use any Asterisk module that needs a timer, like MeetMe, you have to use a module named dahdi (previously named zaptel). DAHDI has one module for each Digium supported card (B410P), and a dummy module (named dahdi_dummy) if you don’t have a hardware card, like me. The problem appears when you […]

Django: How to find the url/path you’re into, in a template loaded by a generic view

In a Django project, I have a template that is used by two urls, which is quite common (generic views, using ‘create_object’ and ‘update_object’). The problem is that I had to add a supplementary menu just when the template is loaded from the ‘update’ generic view, and not from the ‘create’ generic view. Making the […]
