  • Didn’t really think about that one but you’re right damn… (Looked it up, and it depends on the bit depth etc, but it’s around 3.2Gbps for the display settings if I’m correct)… So that explains a lot

    Gigabit is capable of like 720p@30Hz which it probably should be able to fall back on, but I understand why they wouldn’t do that haha. 1080p@15Hz is also possible :)

    It gets even better, each function of the port also needs proper support from the cable. Often cables do not support the full spec of usb to cut costs.

    While the symbols in the post are often put on computers, for usb cables this is seldom done (only a few brands do).

    Source: had to find a cable that supports both DP and PD to connect a portable external monitor after I lost the original cable. (1/9 cables worked)














  • In practice, there are several types of CAPTCHAs: text-based, image-based, audio-based and behavior-based.

    Computer scientist writing an article about captchas doesn’t know that proof-of-work captchas exist… Such a joke.

    Of course those don’t do much against automated fake form filling, but against DDoS they’re THE solution.

    Proof of work (PoW) captchas make the (computing) cost for the attacker exponentially higher than for the website. Basically the website creates a challenge, which has to be solved by the client/attacker before getting access to content. Best of all the website can set the difficulty of the challenge to anywhere from instant to seconds to solve, so normally the users don’t even notice it (as it runs in the background) but once someone starts DDoS’ing the difficulty goes up.
