Things I've learned, documented quickly
Today I needed to create a blank .img (raw disk) file, format it with a filesystem, mount that filesystem, and put a file on it. The reason for this was absolute laziness: I didn’t want to put a file on a flash drive and then go to my basement to plug it in to a server. Instead, I wanted to use the Dell iDRAC Virtual Media option to mount a disk with the necessary file. So, how does one create such a disk file?
I finally learned how to commit a shell script in Git on Windows that will have its executable bit set in Linux when the same repo is used there:
I’ve been playing around with Google TV boxes, as well as actual TVs, and I’ve learned a few things about customizing them. NB: Naturally, as operating systems and services get updated, this information will become outdated.
Today, I made a terrible mistake. I attempted to do a live upgrade of a Windows mirrored disk pair to use larger SSDs. The procedure started normally, but in the middle of one of the resync operations, I realized that I would need to break the mirror (again) in order to resize the partition because mirrored partitions are not resizable, so I naively stopped the resync. Bad idea. The source drive ended up in an “invalid” state, which Windows refuses to work with in any way, it would seem.
I didn’t learn this recently. In fact, I realized that it’s been buried in my head for a while, until a coworker happened to mention that his screen looks a bit… off.
Some interesting links related to OpenStreetMap and raster/vector tiles:
Certain electric car charger models (which shall remain nameless) have a penchant for breaking. One specific type of issue I’ve encountered multiple times is when the handle is plugged into a car, but charging does not initiate, and the car displays a message along the lines of, “verify everything is plugged in securely”.
After a significant amount of trial and error, I figured out how to use SatPy to create a GeoColor image from GOES satellites. I tried doing the same with Himawari L1 data, but the process kept running out of memory and crashing. Not sure why.
