GPG key

Yesterday, I’ve created my personal GPG key.

The description of GPG (or GnuPG) from the official website is:

GnuPG is the GNU project’s complete and free implementation of the OpenPGP standard as defined by RFC4880. GnuPG allows to encrypt and sign your data and communication, features a versatile key management system as well as access modules for all kinds of public key directories.

High Velocity Web Framework For Java and Scala

This framework allows you to quickly build web applications with Java (and Scala, but I’m sticking to Java for now).

Reset a Heroku database

I’m currently developing a Play! application, and I use Heroku to deploy and test it.

But sometimes when deploying it, the application crashes when trying to start up. What happens is that the database contains data that are in conflict with the new schema that I’ve deployed (eg. new required foreign keys that don’t have a value…).

Piwik to replace Google Analytics

Since the PRISM “scandal” (yes, everybody already knew that the USA have been spying on us at least since 2001), we see lots of open-source solutions emerging to replace the “old” proprietary (and potentially a bit too curious) web-applications. A good example is DuckDuckGo, an anonymous Internet search engine that has seen its traffic exploding after the revelations (1.5 million queries / day on 01/01/2013, almost 3.5 millions queries / day today). You can see the evolution of the traffic on their website.

I’ve been trying for a while to clean my digital footprint (I still have a lot to do), and to reduce my dependency to proprietary services, but some major solutions are unavoidable, like GMail (or YMail). A few weeks ago, I’ve managed to replace a Google service, Google Analytics, by an open-source, self-hosted application, Piwik.

Comics Calendar

I’m an avid comic books reader, mostly from the Marvel franchise (X-Men, Spider-Man, Avengers…), and some DC too (Batman, Superman…). But every series has its own monthly release date, which makes difficult to follow what the current issue is for a series.

That’s why I’ve developed an on-line calendar that regroups the release dates for all new comic books issues. The data are retrieved from ComicVine, which is a huge wiki-based website for comics.
