MariaDB/MySQL slides for HA and performances tuning

21 June 2013 in Databases, Debian, Hi-Tech, Linux

I recently gave a training on MariaDB/MySQL regarding performances tuning and High Availability. You can find here the slides I’ve made for it (french). Some subjects related in that document are replication master -> slave, master < -> master and Galera Cluster. You can download the PDF here or see it directly on SlideShare : I hope this will help some of you to get a better understanding on some advanced features.

Selfoss : An elegant RSS reader

19 June 2013 in Android, Debian, Hi-Tech, Linux, Web

Selfoss is a self-hosted RSS reader solution. It could be compared to Tiny Tiny RSS or Feedly. I liked to test that nice solution. But I’m still staying with Fever, as there is no Android version working with Selfoss (only an old one exist, but doesn’t work) and the web interface is a little bit slow (compared to Fever). I hope this will be better in a short term as this is the most elegant Open Source version I’ve tested for now.

Firefox Sync : build your own sync server

3 June 2013 in Debian, Hi-Tech, Linux, Web

I’m very happy of Mozilla Sync service and trust more in Mozilla foundation than Google for my datas. Anyway there is a thing that I don’t like : sharing my passwords into the cloud ! That’s why I decided to create my own Sync Server. I want to thanks Mozilla for their work, it works like a charm :-). So now I don’t use Mozilla server anymore, but my own. Here is the documentation on how I did that.

Switch audio output to another USB device

1 June 2013 in Debian, Hi-Tech, Linux

I recently talked about my new keyboard and the output sound directly on the keyboard. That’s a great thing, but depending on your distribution and the desktop you’ve installed, it may not work out of the box. That’s why I’ve written a documentation to make it work. In addition, I’ve modified my awesome configuration to get special music keys to work like a charm :-)

20 May 2013 in Debian, Hi-Tech, Linux, Red Hat

When you manage outgoing emails through SMTP, you may sometimes need to test if a service is able to send correctly emails and itself check that there were no issue during sending. You can create a black hole for a specific domain and Postfix will answer from the same manner as if it is ok. It also permit to test Postfix sending capacities on a server.
