   Matrix printers can actually do quite a lot... depending on the models, you can change fonts, use bold, underline, sometimes italic, double-width and double-height characters and even graphics (although often are relatively low resolutions

   And any clue about what they were doing with POPCNT? Does it has any particular use in encryption?

   I'm not sure I would source non-Chinese electronic components from Aliexpress... (unless it's just to play with them, definitely not for a product): you might need to check their reliability and quality. Pretty sure that Sensirion

   Not everyone but almost... and it's the same in other places (was already the case in Buenos Aires when I went there a few years ago). And of course when you tell people that there are better alternatives, many of them don't want

   Detection by airport security might probably be avoided using the right type of explosive. I have no real idea about this, but I suspect that any nation-state with enough budget and know-how can manufacture undetectable or very hard-to-dete

   Is that the same one that sometimes asks you to click on motor cycles and zebra stripes in a loop and you never come out? (this happens often especially if you're on a somewhat uncommon IP address, like an IPv6 /48 with just a few

    Of course consumers will get some benefit in return, like heating seats for free instead of paying a subscription to turn on a resistor... right?

    Not exactly what you're looking for, but there's Shell in a Box (see https://github.com/shellinabox/shellinabox ), that can create a terminal on a web page, and expose an actual terminal application running on

    Yes I realized later that OT might have two meanings, and the most probable one is not the same everywhere... but too late to edit.

    Cell phone coverage in many places is just horrible. You might get good coverage and signal quality, but the network just can't follow when everybody is watching youtube at 4K resolution on their mobile connection. Sometimes even regul

    ISDN... before it was too expensive, now you can't get it anymore. VoIP with G.722 is wonderful when it works (you can't just call everybody with it, because both parties must support it). G.711 (A-law or µ-law depending on which

    I love landline phones (when they work right, which is not the case everythere) because usually they have better sound quality than mobile (which can be good-to-horrible depending on network quality) and almost zero latency. But it's t

    Sure, it saves development time & money. But if they anyway need some kind of custom interface... problem is, the lifetime of the tablet is way lower than a corresponding "dumb" system. I'd see the advantage of using a ta

    Is this tablet doing anything else beside the small user interface? Is that interface worth a tablet, or can it be done with 3 push buttons, a small LCD and a microcontroller?
