Thoughts on Chrome OS

After a long time of ignoring this platform and only ever having tried CloudReady (which this is based on), I tried to install ChromeOS on some of my older machines. While the older ones like Thinkpad X200 performed poorly as expected, newer machines performed well. I’ll elaborate on a few different points in which I see the value of this OS. Installation There aren’t many options to choose from and when installing this OS, you are going to wipe your existing OS.

My personal cloud server upgrades

About a year ago I decided to revamp my personal cloud. Main objectives were to make it more manageable and use as much pre-made software suites as possible instead of maintaining my own. This article is about what software I chose, which software it replaced as well as reasons why this was done. Oh and of course, I’ll start with hardware. Hardware and Performance Considerations old solution: Thinkpad X200 + ultrabase

Forza Horizon 5 performance hit on VFIO system

I am trying to document how much of an impact VFIO has on gaming performance. More benchmarks will come in the future, but for now, let’s look at Forza Horizon 5. I picked Forza Horizon 5 to do these tests as it is somewhat demanding and has a benchmark mode which displays somewhat interesting results. The graphics are all maxed out and both vsync and g-sync are off, in game and in any applicable place.

Moving many btrfs subvolumes to another disk

As I was migrating my whole system over to btrfs the other day, I came across my docker volume which was already btrfs and using subvolumes. This was of course intentional, however, I had no idea how to properly move those subvolumes to the new disk. Surprisingly, it was somewhat easy. Btrfs has send-receive functionality which you can use to move data between disks (even do stuff like incremental backups, replication and so on.

How to remove supervisor password on older Thinkpads

If you lock your 2008-2010-era Thinkpad with a supervisor password and forget it, there is not much you can do. Unplugging the battery won’t help (although I have heard that supervisor password on some models can be removed this way) and getting Lenovo to fix it for you can be time-consuming, especially compared to how easy to service and how well documented these machines are. This tutorial could work on other laptops, not only Thinkpads.

The smart and easy ACME client

After trying out different ACME clients, like dehydrated or getssl, I always came back to certbot. But now, I have finally switched to, which, as a simple shell script, is compatible with my KISS ideology. It is used by some big projects like FreeBSD and Proxmox, for their SSL needs. Lots of features Out of the box, you get support for over 70 DNS hooks (from cloud providers like Amazon to actual software like PowerDNS).

How to enable Chrome's dark mode on Android
