Interesting, I mostly followed this approach which is to basically never use those constructs unless you are 100% certain you know what will happen.

TLDR;

> Specifically the cost for useCallback and useMemo are that you make the code more complex for your co-workers, you could make a mistake in the dependencies array, and you're potentially making performance worse by invoking the built-in hooks and preventing dependencies and memoized values from being garbage collected. Those are all fine costs to incur if you get the performance benefits necessary, but it's best to measure first.

Same thing with asbestos, there is a non-zero background level in the air because it was used in so many products for a long time.

Could you elaborate more?

Well, the "logic" for fakie is that your tail remains the reference even though you are popping backwards. Therefore you would spin the same direction for fakie fs 180 as you would for regular fs 180.

> I never figured out how to classify nollie/fakie board and lip slides front or back

Yep this one still trips me up to and is great argument over some beers. Especially when you introduce flip tricks into them as well :p

Woah! That's so random, I recently came across your article a few months ago. Great work and small world :)

I have a private discord and github for the project I can add you too. I eventually plan to open up the discord for anyone once we get a little further in the rebuild.

Wish there was a good way to DM on HN, I can send you a discord invite. Or if you happen to be on slap let me know.

Haha Suskis are still valid. They've grown on me over the years, especially when pinched on a ledge.

You can also steez fs flips like this as well, aka the Muska flip

Ah yes! and

One of my other favorites:

On circle rails there is "no such thing" as fs overcrook, just fs nosegrind, and there is no such thing as bs nosegrind, but there is bs overcrook.

At least that's how magazines seem to classify it.

Here's a fun one to debate with your skate friends, nollie and fakie tricks are "swapped".

For example:

- nollie fs 180 and fakie fs 180 (fs half cab) are two different directions: nollie fs 180 is in front of you and fakie fs 180 is behind you going blind

- nollie 5-0 and fakie 5-0 (fakie switch nosegrind) lean differently on the grind: nollie 5-0 you pop off your nose and land on your back truck, fakie 5-0 you pop off your tail and land on your front truck

- nollie noseslide and fakie noseslide are different motions to get into the slide: nollie nose you pop off nose and land on the nose in the ledge, fakie nose you pop off tail and land on the nose but you do a sort of half cab

The key distinction in the argument is that in fakie, your tail is always considered your "tail". Therefore you treat any derived tricks as being "backwards". In the 5-0 and noseslide examples, you're still popping off the front of your board, but you classify it as nose or tail based on if it's nollie or fakie.

There are caveats though such as "fakie crook" where if you kept the rule it should be "fakie suski", which no one says.

There's a million arbitrary and nonsensical rules in skateboarding which is part of the reason to love it, especially for something that "has no rules".

And remember, never carry your board by your truck :)

Yeah for sure, the way the foot wraps with the board is the visual cue. It has led me and friends to some fun debates in a game of skate i.e. "that wasn't an impossible", so I was hoping to be able to point to some ridiculous mathematical definition the next time it comes up.
