    I started enjoying Netflix more when I realized I shouldn't be looking for stuff I knew of from elsewhere, but rather explore titles, rate, and help their algorithm to suggest thin…

    My 2 cents: many file systems do not have a file locking feature that can enforce file locking. In unix-like systems, file locks (e.g., lockf(3)) are "advisory" rather than mandato…

    Speed is one concern but far from the main reason. You couldn't use a typical-length RSA key to encrypt a large chunk of data because there's a max input size for any given RSA key…

    Speaking for the Bay area, public transportation here is shockingly bad, even for something as routine as getting to the airport. For someone living in the valley to get to SFO (ab…

    For HTTP clients and servers, I've not had too much trouble with cpp-netlib. It's heavily boost-based, and it uses Boost::Asio for concurrency and SSL handling, but if you're famil…

    Correct. I didn't mean slow implementation, I meant slow enough on modern hardware using the fastest implementaiton.

    I may not understand the whole context, but if you're using PBKDF2 for key derivation, you don't want to use something that works "fast". You want whatever algorithm/iteration comb…

    I've been thinking about this very problem---recovering a forgotten encryption password without trusting a third party. The state of the art seems to be 1. Print it out on paper an…

    I've read a few bits and they're all great one way or the other, primarily because chapters on specific projects are written by their primary authors. A couple of good ones Nginx: …

    While you have a valid point, Flutter has some pretty deep and well-trained computer vision code that can't be replicated in a month or two. In addition, even if one app (say iTune…

    It's on LWN. 90% of programmers who go there really do need to know memory in the detail Drepper talks about. I see your point though - I fully expected the title to be linkbait to…
