  • I’ll see if I can remember any interesting ones. One is a portable satellite messaging device using this:

    Simplest case would be a small waterproof box with a battery and a board and MCU inside. UI would be a phone communicating by wifi. The box could run a web server so you would operate it with a phone browser and not have to install an app. Nicer version could have a minimal keyboard and display, like from a Lilygo Deck.

    Note: this functionality already appears in a few high end phones (Iphone 15, Pixel 9) so it may make its way into more affordable phones after a while. Thus, the special hardware might stop being interesting. Meanwhile there are things like the Garmin Inreach which require over-expensive monthly subscriptions.

    Another: a privacy oriented health monitor something like a fitbit (it wouldn’t have to be as small), that communicates with your computer or phone but doesn’t send anything to Google etc.

    There were a few more. I may make another post later if any come to mind.




  • It would help if you said what your interest and skills are. If I wanted a small GNU/Linux desktop or server thing I’d just write it myself. But I can suggest some Android apps since I’m not set up to write those at the moment.

    There used to be a GNU project task list but it no longer has concrete suggestions, oh well.

    Actually one desktop thing I’d like is a gnus.el back end for Lemmy (if you don’t know what gnus.el is, this project isn’t for you). I might pursue that someday but I’d rather that someone else do it so I can use it.

    Another thing I could use: a Pandoc exporter for bbcode, for some other forums I visit. So I could easily convert Org or Markdown files to BB. Pandoc is written in Haskell so that could be an interesting language learning project too, if you don’t already use Haskell. There could be an Org exporter as well, or instead (written in Emacs Lisp).

    Those are off the top of my head. Maybe I can think of a few other things too.

    “Make this” evokes hardware projects for these. I have many ideas for those that I can’t really pursue myself, as I’m not a hardware guy and don’t have the resources for it.




  • I didn’t watch the video but I don’t think there is any phone that lets you avoid having your location tracked. If there is wifi near where you want to use the phone, you could run a voip client on on a wifi-only tablet, perhaps.

    I’ve been wondering whether satellite communications gizmos with no GPS allow any type of precise location tracking from the satellite. I’ve been interested in this, which lets you exchange text messages at fairly low cost (about 2 cents per 50 byte unit). Besides possible privacy advantages, it also lets you communicate where there is cell coverage:

  • In chess there is a fairly common situation where you are in first place in the last round of a tournament, 1/2 of a point ahead of your opponent (you get 1 point for winning a game and 1/2 point for a draw). So if you win or draw the game, you win the tournament and get a lot of money. If you lose the game, your opponent wins the tournament and gets the money. You get 2nd place, i.e. less money possibly split with other competitors.

    That means you can choose a safe playing strategy that likely leads to a draw, while your opponent has to choose a risky strategy with higher chances of winning.

    (Some chess context: high level games are usually drawn. They are only won by someone making a mistake. Also, the first move (white pieces) confers an advantage, so it’s usual to seek winning opportunities if you have white, while just trying to hold the draw if you have black. To attempt winning with black requires seriously risky play. Bobby Fischer basically conquered chess in the 1960’s by constantly trying to do that, which required playing with maniacal intensity all the time).
