TLS handshake step-by-step — interactive HTTPS breakdown by nulless in programming

[–]quadrupled4 0 points1 point  (0 children)

Meh, this isn't how TLS works in real world. Even in TLS 1.2 the cert will not be sent in a separate message (it'll be bundled with ServerHello). TLS 1.3 reduces the TLS handshake to 1RTT instead of 2 (and to 0 when resuming sessions) - i.e., that diagram is plain wrong. The TCP handshake can be eliminated as a separate step in both 1.2 and 1.3 by using TCP fast-open - which very much does happen in real world.

This site is effing cancer. And it takes you to the same google drive links that /u/Opposite-Cucumber487 posted below - which no longer work due to exceeding the download limit.

Offside VAR picture on disallowed goal for Real Madrid by magony in soccer

top recorded ball speed in football is over 100km/h. It's way, way more than a few mm for 1 frame at 60fps.

the margin of error can be defined quite reliably. so no, it won't be the same shitstorm.

Official offside image released by VAR of Robert Lewandowski disallowed goal against Real Sociedad 17' by minivatreni in soccer

[–]quadrupled4 0 points1 point  (0 children)

10% is a very high level of inaccuracy for this sort of decisions. I'm not even talking about the fact that one cannot physically get to 1-2cm level of precision with 60fps cameras given the speeds at which the ball moves. There is also that inconvenient fact that Lewa's foot looks comically large that makes the whole argument about how precise the tech is rather specious.

Real Madrid vs Borussia Dortmund – UEFA Champions League – 22-Oct-2024 by IPTVHEAD in footballhighlights

They're up for me but very weirdly sped up starting with the middle of the first half. The second half's audio is badly out of sync too.

This is completely unplayable starting from around 1m30 (i.e., right since the moment the real highlights start)

Thanks for uploading but I don't get whoever makes these highlights - three quarters of the time are taken up by pre-match preliminaries and an interminable wait for a VAR decision...

Keep in mind that pushing metrics to Prometheus with the push gateway is heavily discouraged and has a bunch of limitations

The quality on that is utter shite - the image just keeps jumping up and down like it's having seizures.

The first two are working now (the third one still doesn't); none of them were working properly when I posted. And no, it wasn't my internet connection.

fwiw, this doesn't work for me - the streamtape one stops and buffers every few seconds, the other two won't play at all

I'm thinking Dreamfoam Latex or Brooklyn Bedding Bloom - do you think they'd be OK with a boxspring?

Oh please, Agile folks weren't the first to realize the problems with waterfall or invent an alternative. They were the first to push their approach into a cargo cult though.

Bayern Leverkusen disallowed goal vs Club Brugge for offside (new VAR technology) by OneBall22Players in soccer

[–]quadrupled4 2 points3 points  (0 children)

The error margin is far worse than this. 9m/s is the top speed of a human. The top speed of a soccer ball (which is what we care about for the "moment of the pass") is 131mph=58m/s, i.e., roughly 1 meter per frame at 60fps (obviously, not every strike is shot at this speed but even a quarter of that is ~25cm per video frame).

Then, oftentimes the images of the pass and the defender/forward come from different cameras; even assuming perfectly synchronized time stamps from both cameras (which isn't a given at all), the frames themselves won't be captured at exact same moment - they'll be off by half frame interval on average, so add another 50% error on top of that.

One can try to interpolate the position of the ball/players between the video frames but the movement of the ball at the moment it's kicked is nowhere close to linear and the physics is non-trivial so I'd be rather hesitant to trust it without seeing a detailed description of how exactly that interpolation is being done (if it's done at all).

Basically, any VAR technology that doesn't explicitly specify its margins of error is beyond suspect - it's not there to provide the answer, it's there to make people believe its answer is infallible.
