Neo4j: a pretty graph database

6 September 2014 in Databases, Events, Hi-Tech, SQL

I forgot to talk about 1 meetup I’ve been regarding Neo4j. A friend (evomusic) talked to me about it and as I’m curious, I went to this meetup in July. Neo4j is a highly scalable, robust (fully ACID) native graph database. Neo4j is used in mission-critical apps by thousands of leading startups, enterprises, and governments around the world. I you don’t know what is a graph database, it’s a very good introduction and will help you to understand what it is and how it works.

Mediawiki: make your search case insensitive

31 August 2014 in Databases, Hi-Tech, Web

For several years, I was wondering how to make Mediawiki search case insensitive. I didn’t really had time to look at it until I was really fed up. That’s why after a few seconds of search, I’ve found an extension for Mediawiki which is working perfectly called TitleKey. The TitleKey extension provides a case-insensitive title prefix search.

Deploy a logs management infrastructure (Elasticsearch+Kibana+Fluentd) with Ansible

15 August 2014 in Ansible, Databases, Hi-Tech, NoSQL, Web

During the last weeks I started to play with Elasticsearch, Fluentd and Kibana. I made a documentation to help on deploying it easily. As you may know, I’m an Ansible fan, so I made Ansible playbooks to deploy a complete infrastructure (server and clients). They will deploy this kind of architecture: On the client side, Fluentd clients will get syslog and Nginx logs, to send them to the Fluentd server. On the server side, a Fluentd receiver will be there to get data from other Fluentd clients.
