+Now I am thinking about an offsite backup of all this local data. The problem is that all the data remains on a single physical location: My local MicroServer. What happens when the house burns or my server, including the internal disks and the attached USB drives, gets stolen? My first thought was to back up everything to the "cloud". However, the significant issue here is the limited amount of available upload bandwidth (only 1MBit/s).
 
 The solution is adding another USB drive (2TB) with an encryption container (GELI) and a ZFS pool. The GELI encryption requires a secret key and a secret passphrase. I am updating the data to that drive once every three months (my calendar is reminding me about it), and afterwards, I keep that drive at a secret location outside of my apartment. All the information needed to decrypt (mounting the GELI container) is stored at another (secure) place. Key and passphrase are kept at different sites, though. Even if someone knew of it, he would not be able to decrypt it as some additional insider knowledge would be required as well.

 ShellCheck, a shell script analysis tool written in Haskell, is run on Gemtexter ensuring that all code is acceptable. I am pretty impressed with what ShellCheck found. 
 
-It, for example, detected "some_command | while read var; do ...; done" loops and hinted that these create a new subprocess for the while part. The result is that all variable modifications taking place in the while-subprocess won't reflect the primary Bash process. ShellSheck then recommended rewriting the loop so that no subprocess is spawned as "while read -r var; do ...; done < <(some_command)".  ShellCheck also pointed out to add a "-r" to "read"; otherwise, there could be an issue with backspaces in the loop data.

 One benefit of using open-source software is that it doesn't cost anything, right? That's correct in many cases. However, in some cases you still need to spend a significant amount of time configuring the software to work for you. It will be more expensive to use open-source software than proprietary commercial one if you aren't careful.

 ### On Kubernetes
 
-Now have a look at Kubernetes (k8s), the current trendy infrastructure thing to use nowadays. Of course, there are many benefits of using k8s (auto-scaling, reproducible deployments, dynamic resource allocation and resource sharing, saving of hardware costs, good commercial for potential employees as it is the current hot sauce of infrastructure). But all of this also comes with costs: You need experts operating the k8s cluster (or you need to pay extra for a managed cluster in the cloud), increased complexity of the system (k8s comes with a steep learning curve). The latter not only applies to the engineers managing the k8s cluster -  it also applies to the software engineers, who now have to develop 'cloud native' applications and, therefore, have to change how they developed software how they used to. They all need to be re-educated on what cloud-native means,
