Going low-tech: Blogging with jekyll

Most of the groundwork is done, therefore I can finally explain what happend here:

I started my blog on blogger.com because it seemed like a quick and convenient way to publish my occasional article about GNU/Linux, life and technology, but over time I got a bit annoyed with it. The system generates the current view dynamically with heavy use of javascript which leads to parts of the page breaking frequently if one of the content delivery servers doesn’t respond in time. On my blog, prime candidates for this kind of breakage were the top and the slide-in navigation. A blog with most of the navigation missing? No, thanks. In addition to that I had no control over the source code and the rich text editor behaves nothing like my usual tools of the trade. Those were itches I definitely wanted to be scratched.

The solution: Running my own blog somewhere safe.


Arch Linux: Encryption and multiple hard drives

There are many guides out there explaining how to do a full-system encryption on Linux, but most of them, including my own, have a little flaw: They focus on systems with exactly one hard drive. However nowadays hard disks are cheap, SSD+HDD combinations are getting more popular and even some notebooks (like my glorious Thinkpad T520) have multiple drives.

Although it’s not that difficult to adapt those guides in a way that all drive are encrypted, naive double execution of cryptsetup will lead to being asked for a passphrase multiple times at boot. I find this behaviour highly annoying and will therefore explain how to circumvent this situation without omitting security.


Google Plus: How to claim authorship of your blog posts on blogger

When using google for research purposes, you’ll often come across search results having a little picture aside and linking to the google+ profile of the author. See the picture below for an example.

The purpose is clear: Linking abstract information on the web to the people behind and making people with google+ profiles more prominent. But how can you get the badge for your blog? Well, there are hundreds of guides out there describing what to do and what to link where, but I believe most of them tend to be overcomplicated and not suited for google’s own product: Blogger. Therefore I decided to write down the necessary steps to accomplish this feat.


Arch Linux: Repair an encrypted system

The following article is for novice to medium users who broke their encrypted system, be it by accident, stupidity or choice. It’ll show you how to regain access to your hard drive and conduct a repair attempt, but not tell you how to repair a broken encryption (e.g. corrupted headers), because without having countermeasures in place (e.g. backups of said headers) your data is probably lost for good.


Arch Linux: LVM on top of LUKS - 2013 Style

Having not installed arch linux for some time, I was kind of surprised that the installer got abolished and replaced with pacstrap. Simon Dittlmann did a great job describing an encrypted setup on arch linux, but his guide is a bit outdated.

I couldn’t find a guide utilizing the current method of installing arch linux, so I decided to update Simon’s guide to 2013. I’ll explain setting up LVM on top of an encrypted partition, because it’s easier and more convenient than the other way round.

Advice: You should definitely backup your data and read the Beginner’s Guide to get comfortable with the installation process.
