  • The --hold feature was introduced with snapd v2.58 which was released as recently as Dec 1, so less than 9 months ago. So I would consider this a relatively new feature.

    Furthermore, as best as I can tell from the documentation, there isn’t even a way to configurably hold updates in general or for a specific package like can be done with apt-preferences; refresh.hold only allows 90 days out.

    I think it is a perfectly valid criticism that the snap developers didn’t implement this feature at all until well into the life of the product and then, even then, done begrudgingly at best evidenced by the minimal implementation.

    Now, I feel like I did my research, but feel free to let me know if there’s something I can do better or if you have any other general life advice for me.



  • Try putting it in the freezer for a few minutes before trying to read the data. Or heat it up slightly.

    This is an old trick I’ve used to recover data from a hard drive or two. I suppose it could help if the problem with the SD is some kind of microscopic fractures.

    It should be emphasized that this is just a temporary workaround at best.


  • The console is the virtual terminal (VT) seen initially at boot before the desktop login starts up, or where you land if there is no desktop, and where the kernel spits its raw output. It could even be configured to be a physical serial port.

    I’m using the term in a similar manner to describe the virtual terminals spawned at boot (typically 7 of them) and occupied either by a login prompt (getty) or the desktop session, and switchable with Alt-Left/Right or using the chvt command. These are analogous to the real terminals of old such as VT100 or even typewriters.

    This is in contrast to what we normally call a terminal like xterm or Konsole which runs in the GUI where it is resizable, zoomable, etc. The console, and virtual terminals, are pretty limited in the interactivity they have. For instance, there’s no mouse interaction or copy-paste functionality, at least not without some exotic setup.


  • My C.H.I.P is still rocking in a special project sitting on my desk.

    For those that don’t know, it is like a RPi but smaller, cheaper (originally $9), more I/O, and had WiFi & Bluetooth (whereas the RPi2 of the time didn’t). DIPs (aka hats) were available giving HDMI, VGA, and other capabilities including the PocketCHIP which turned it into a handheld computer by providing a display, button-keyboard, and battery.

    While the project is now defunct, kept alive only by the community, there was an attempt to resurrect it in concept and form-factor as the Popcorn Computer on Kickstarter. But that one didn’t fund so, alas, it is now an endangered species.
