  • So if I’m developing a garage door opener using ESP32 RISC-V module, I’m not a RISC-V developer? The dev tools and the cross-compiler only come in x86_64 variant, they simply won’t work on RISC-V laptop. But at least they provide a Linux installer.

    The only use case I can think of is to build Debian packages on a target architecture without cross-compilation, because many packages do not support cross-compilation, but it’s more an issue of poor build scripts.



  • I have discovered cold infusion coffee just last week. It’s a surprising way to salvage ruined coffee roast. Cool water until there’s some ice in it, or just dump ice in water, then dump your badly roasted coffee powder, shake, and leave in the fridge overnight (not the freezer). Strain the grounds, reheat in the microwave and drink (or just drink it cold and with grounds, whatever works for you). Ideally you should use coarse grind size, but it’s mainly because it’s easier to filter it.


  • Coffee tends to not have any upper price range, you always can find something even more exclusive than beans pooped by a rainforest squirrel. So whatever marketing trend is occurring, it likely won’t impact most consumers, who drink it for the caffeine content not the taste. Maybe in 10 years when the trend soaks down to the bottom shelf of the supermarket, I will have a bit differently tasting beans in my free office-provided coffee. But it’s already 95% Robusta with 5% mystery beans to provide foam, not enhance the taste. They could add fried soy beans for all I care, it certainly won’t make the taste worse.

    Anyway, to answer your original question, I’m not seeing any “100% Robusta char-fry” coffee ads in my city.


  • Nothing like that, just more automated coffee machines with credit card terminals across the city. It’s a progress I guess.

    I never understood “100% Arabica” trend. It’s just sour. The fancy expensive coffee made by a barista on a shiny manual espresso machine tastes acidic to me, and the best-tasting coffee is what our free office-provided automated machine makes from bottom-shelf beans. Am I supposed to fix it with cream and sugar? Do I have some rare gene mutation that makes me sneeze when looking at the sun and makes 100% Arabica coffee bad-tasting?








  • Laptop has keyboard, you can type your password with the same speed as pressing your finger and waiting for it to unlock.

    Most casual users won’t even know that their laptop has a fingerprint sensor.

    When a company needs a proper security, they buy every user a hardware token like Yubikey.

    But most of all, it comes down to the tradition. Manufacturers won’t add fingerprint scanner because users do not demand firgerprint scanner. Users do not demand fingerprint scanner because they are used to have no fingerprint scanner. Try removing a fingerprint scanner from a phone, you’ll see your sales drop like a brick.
