About a year ago I counted myself lucky that I was able to order a heavy weight BTO laptop on company's account. 8GB Crucial RAM, 250GB Samsung EVO 850, i7 4612Q cpu, Full HD screen, NVidia GTX970, lighted keyboard and all that comes with such a high end laptop. 4 weeks later it was jacked from my car.... I still get angry thinking about it. 

One of the reasons I left it in the car is that is weighs almost 3kg. Well I learned a few leasons at least.

Since then I build up a gaming rig which runs Windows 7 with a Steam client running. I can play any game supported in Steam while I connect with any system able to run a steam client. I even managed to play Minecraft while sitting behind a Atom powered netbook or a Raspberry Pi 2.

For some time now, my cms was reminding me there was an update available. The host that it is hosted on however was still running CentOS 6, which has an older version php among other things. At first I was inclined to start using the rackspace users repository which enables you to choose between a number of releases for just about any hosting related software and more. Including later releases than normaly supported by the default CentOS/RHEL repositories. But around the same time CentOS 7 was just about to be released, so I decided to wait and migrate the hosting to a new host running CentOS 7.

Nvidia does not have a good reputation in the Linux community, even Linus Torvalds himself has expressed dissapointment with the company. And as I have found out, installing drivers for any of their GPU cards is not as straight forward as you hope it would be. But nonetheless, I have gotten my Linux Mint OS, or applications to be more precise, to use the dedicated Nvidia GPU instead of the intel GPU which is part of the CPU.

CentOS 7 has been released about a month now and after making several test vm's and finetuning a cobbler install, I decided the best way to find my way in this new major release of CentOS, is to use it in 'production'. The reason I put quotes on production is to avoid the argument that my home IT infrastructure is not a production enviroment. But then again, it is becoming a resource I'm using all day, both at work and at home.

A while ago I started using self-signed certificates for a number of subdomains. Although browers would still displaying a warning that the certificate was not secure (as in validated somehow), it did encrypt any communication between the client and the server, thus introducing more security. It did bug me however, that the security warning comes up. 

The cost of a SSL certificate is not that much, but with a dozen subdomains it would add up. A wildcard certificate is an option but those arent that cheap either. A friend of mine pointed out that there is a free of charge service for relatively simpel (sub)domain certifcates. It doesn't include extensive validation but it does provide a certificate that is accepted by most modern browsers as valid.

So, as of today, this website is hosted with a valid ssl certificate and in the following days I'll be installing certificates for most subdomains as well.
