The Percona replication manager (PRM) is a framework using the Linux HA resource agent Pacemaker that manages replication and provides automatic failover. This covers the installation of the framework on a set of servers. The PRM framework is made of 4 components: Corosync, Pacemaker, the mysql resource agent and MySQL itself.
It’s easy to setup, better if you already know how to use Pacemaker and it works like a charm. In fact it setup a master and x slaves.
monit is a utility for managing and monitoring processes, programs, files, directories and filesystems on a Unix system. Monit conducts automatic maintenance and repair and can execute meaningful causal actions in error situations. E.g. Monit can start a process if it does not run, restart a process if it does not respond and stop a process if it uses too much resources. You can use Monit to monitor files, directories and filesystems for changes, such as timestamps changes, checksum changes or size changes.
You know that I recently switched to i3. One of the first thing I wanted to change is the status bar which is not optimal for my usage.
After researches, it looked like that i3blocks it the best alternative. So I contacted the creator (Vivien) and had very good exchanges with him.
I’ve made pull requests and suggestions to integrate missing checks, faster one that I developed and with colorization depending of the contexts.
I recently needed to install an IRC bouncer as I was fed up to launch every say a ssh to connect to an external server, on which I had a tmux running a weechat to get IRC history. 2 problems here:
Sometimes, I forgot to connect on it and missed some messages It was not integrated to Pidgin (what I use for any IM protocol) So I decided to setup a bounce IRC with ZNC!
NAXSI means Nginx Anti Xss & Sql Injection. Technically, it is a third party nginx module, available as a package for many UNIX-like platforms. This module, by default, reads a small subset of simple rules (naxsi_core.rules) containing 99% of known patterns involved in websites vulnerabilities. For example, ‘< ‘, ‘|’ or ‘drop’ are not supposed to be part of a URI.
It’s been a while that I wanted to test NAXSI and it seams working not so bad.
In France, we have the chance to have an ISP/Mobile Telephony provider called Free. They considerably reduced the market price for the Mobile phone communications in 2012. This was very fine for competition and for French people. Now we can have correct prices for Internet and cell phone data. Thanks to Free.
Ceph is quite the same as Free but for storage systems. Since many years, disks array constructors sold us locked solutions with a very high cost of hardware and licenses’ software.
A big and major issue on OpenSSL has been discovered and everybody is talking about it. To get more informations, there’s a website.
