Merging hard drives without RAID?

Some time ago, I noticed that the harddisk of my home server filled up more and more and I needed to add some more space. As this server is made to be as energy-efficient as possible, I don’t use a RAID which I can extend easily. Additionally I don’t like some facts about RAID, e.g. that I can not pull out a single drive and read the data on it on another machine – or that you need to e.g. add four drives to fulfill the requirements for your RAID level. But how can I “merge” multiple drives without a RAID transparently and without much effort? weiterlesen…

Couple your desktop and Android device using KDE Connect

KDE Connect Logo

Most of you will know the app Bushbullet which couples your phone and desktop and gives you access to the notifications of your Android device. This really is a great app with lots of features, but you have to trust in Bushbullet, as every notification is first sent to the Bushbullet servers and after that to your desktop computer.

How to get A+ ranking at the Qualys SSL Server Test

Qualys A+ SSL Security Ranking LogoReading so much about malware, security issues in software, hackers and the NSA affairs, I am also aware that is crucial to secure any digital device and protect your own data. Encryption of connections between client and server is an essential part of this. Of course, it may be hard to achieve perfect security, but often security issues are founded in a lack of knowledge or because someone doesn’t have the time to do things right.
