  • permanently attached USB SSDs are supposed to be mounted

    Just mount them somewhere under / device, so if a disk/mount fails the mounts depended on the path can´t also fail.

    I keep my permanent mounts at /media/ and I have a udev rule, that all auto mounted media goes there, so /mnt stays empty. A funny case is that my projects BTRFS sub-volume also is mounted this way, although it is technically on the same device.


  • For example, the new .config directory in the home directory.

    I hope slowly but surely no program will ever dump its config(s) as ~/.xyz.conf (or even worse in a program specific ~/.thisapp/; The ~/.config/ scheme works as long as the programs don’t repeat the bad way of dumping files as ~/.config/thisconfig.txt. (I’m looking at you kde folks…) A unique dir in .config directory should be mandatory.

    If I ever need to shed some cruft accumulated over the years in ~/.config/ this would make it a lot easier.


  • They could be very well using the earth’s orbit around the sun to get better resolution - two data points from opposite sides of the orbit. What I know is that the largest “virtual” radiotelescope is literally the size of earth. The data points are synced with atomic clocks (or better), and a container of harddrives gets shipped into a datacenter to be ingested. Thats hundreds of streams (one per antenna) of data to be just synced up, before the actual analysis even can begin. (I’m just guessing after this) At this point, you have those hundreds (basically .wav files) lined up at timepoints they were sampled (one sample, one timepoint column). So row by row, so you can begin to sort out signal phase differences between the source rows.

    I.e to put it shortly: an image is not taken, it is inferred and computed. Not that you even could in the first place, it’s a blackhole after all.
