The main problem was that they ran out of runway while waiting for manufacturers and suppliers to line up and meet their demand. The software was solid, but for hardware products, that's less than half the picture. You need to worry ab

Out of curiosity, how is the embedded story (for both bare-metal and RTOS) in Rust nowadays? I took a look early last year, and I remember feeling that the ecosystem still wasn't as mature as I liked. There's svd2rust [0] and dsli

I've always found "A Painless Guide to CRC Error Detection Algorithms" [1] from the zlib site pretty useful and easy to understand. Once you understand polynomial division, things start making a lot more sense. [1] https:&#x

Safari still does not support WebRTC, and users must enable Flash on sites that require it. They've merged in a few commits [1], but their implementation is still lacking [2]. [1] https://trac.webkit.org/changeset/

I've been using the free-tier of Classeur [1] for taking notes during class, which I then export to a PDF. It's basically an online Math/Mardown editor with pretty much the same feature-set. Maybe I'll try this out and s

No, graph planarity can be determined using Kuratowski's theorem, which essentially states that a graph is planar if and only if it doesn't contain K_{5} or K_{3, 3}. I believe the planarity test algorithm has been improved, such

Technically, you could map jk or something in your ~/.vimrc in order to exit insertion mode, which would avoid the whole issue. :imap jk <Esc> (I don't personally use this, but one of my friends swears by it)
