As a human player (of a not-high standard) I cannot see the spin of the ball directly. I can only infer it from the movement of my opponents bat. So I would wonder that a camera could pick it up in real time.
replyAlso IT'S TABLE TENNIS, NOT PING PONG!

replyAlas HN has finally found its next religious war!
I’ve been feeling a little bored after that whole tabs vs spaces one was settled.
Settled how? Tabs win, right?
replyOnly if you accept that they are set to 8.
replygo fmt
replyI refuse. My code will be formatted according to my own preferences.
replyImagine a world where your editor shows you what you want to see… but saves in a standard format for sharing.
replyThat's what tabs accomplish!
replySo long as my format is the standard one, that all newcomers an unopinionateds see by default and thus my opinions rule forever... yeah! great idea! otherwise... oh hayol no.
replyLuckily Go is only used by people looking for a typed version of Python.
replyTo be honest, if Chinese folks are fine with calling it "ping pong" (乒乓), I'm fine, too.
reply(Also, you sorta can infer the spin from the ball arc or even if you catch a glimpse of the rotating label)
>even if you catch a glimpse of the rotating label
replySome people say they can see the spin from the rotating logo. I can't.
In french, we call that ping pong too. So yeah for ping pong.
replyThat is simply not true. We call it "tennis de table" when it comes to the sport, and we call it "ping pong" when you play at a camping in flip flops.
replyLmao the character used is so cute
replyAs a player myself, and having seen much higher level player than me, reading the spin from the ball rotation (and in fact trajectory) of the ball is a common (if advanced) skill. Sometimes the movement of the bat can be deceptive (since with the same movement, where it contact on the bat, the finger pressure can affect the spin).
replyFor example, backspin/underspin balls will move slower after the first bounce and feel 'damper' while topspin will jump. So it's def. possible (and in fact reliable) to read the spin from the spin and trajectory of the ball.
Visually reading spin is unreliable at all levels; the ITTF passed the two-color rubber rule requiring one black and one red side to neutralize players taking advantage of their opponents being unable to read the spin from watching the ball rotation via twiddling rackets with the same color rubber on both sides, but different characteristics.
replyI can't parse that sentence, can you please clarify?
replyPing pong paddles have two sides, with different characteristics for each side. Now the two sides have to have different colors so your opponent can see what you are hitting it with, where before you could use the same color on both sides and your opponent wouldn't be able to tell how the ball would react
replyThanks!
replyApologies! I left a much clearer edit on screen, and when I noticed I had not commited it, the edit window had closed.
replyAccording to this video it can read the spin:
replyIt was actually called ping pong until it became a trademark dispute, and the sport had to call it table tennis!
reply乒乓. I don't know how it could be more clear that it's not "table tennis".
reply> Also IT'S TABLE TENNIS, NOT PING PONG!
replyWe can also add Whiff Waff to the alternative names!
It's ping pong.
replyIt is ping pang if you use standard pinyin. Also, all these fancy cameras, I wonder if they considered using sound as well? I am a super noob fE player but sound hints are pretty telling of the speed and where and how the ball was hit
replyIt’s miniature table pickleball.
reply> Also IT'S TABLE TENNIS, NOT PING PONG!
replyIs it also MOVING STAIRCASE, NOT ESCALATOR?
Ping Pong is what you play for fun in the basement. The competitive sport is Table Tennis.
replyThis is like software developers who write javascript wanting to be called engineers, isn't it
replyThey're not even controlling a train or wearing a stripey hat. Losers.
replyErm, excuse me?
replyThe professional engineering language is called TypeScript.
JavaScript is what you use to add popups to your GeoCities WebSite.
> professional engineering language
reply> TypeScript

lol all you want. I’ve got 5 people on my team buying food and housing for their families with typescript skills.
replyIt's great that they start somewhere in computers, kuddos to them.
replyVibe code
replyThe ball trajectory gives the spin
replyIt's pīngpāng.
replyI had a look at Google trends for France. Table tennis is slightly more common than ping pong but the latter is much more stable. Table tennis has huge peaks, the biggest one being during the OG in Paris. These parks are not reflected in there ping pong trend
replyInterestingly, for Youtube searches this is the other way, with a much bigger difference in favour to ping pong
