“the output of any sorting algorithm must satisfy two conditions”

Whisper 随想笔记

So that's why my custom sort broke — missed condition two.

“List comprehensions provide a concise way to create lists.”

Whisper 随想笔记

List comprehensions are such a game changer, way cleaner than loops.

“Recursive queries are typically used to deal with hierarchical or tree-structured data.”

Whisper 随想笔记

I've seen people do this with loops in app code, but SQL is way more elegant for it.

“Recursive queries are typically used to deal with hierarchical or tree-structured data.”

Whisper 随想笔记

Yeah, I always reach for recursive CTEs when I need to walk a tree, it's the cleanest way.

“Content-based filtering methods are based on a description of the item and a profile of the user's preferences”

Whisper 随想笔记

But what if the user's taste changes over time? This seems too static for that.

“A typical generative task is as follows. At each step, a datapoint is sampled from the dataset, and part of the data is removed, and the model must infer the removed part.”

Whisper 随想笔记

I've seen this in image inpainting too, not just text. Same trick, different domain.

“Effects let you specify side effects that are caused by rendering itself, rather than by a particular event.”

Whisper 随想笔记

I remember debugging a chat app where I put the connection in an event—big mistake.

“A typical generative task is as follows. At each step, a datapoint is sampled from the dataset, and part of the data is removed, and the model must infer the removed part.”

Whisper 随想笔记

So it's basically like playing a game of peek-a-boo with data, hiding a piece and making the model guess.

“these functions return a null value when no rows are selected.”

Whisper 随想笔记

Yeah had to learn this the hard way, coalesce is a lifesaver.

“Functions passed to event handlers must be passed, not called.”

Whisper 随想笔记

Makes sense, otherwise it runs immediately. I learned this the hard way too.

Wait so I can't just do onClick={handleClick()}? That's been breaking my app for days, oops.

“By strictly only writing your components as pure functions, you can avoid an entire class of baffling bugs”

Whisper 随想笔记

I've been burned by impure components before, this advice is gold.

“You can do things by applying a method on a DataFrame or Series”

Whisper 随想笔记

Took me a while to get that methods change the data in place sometimes, confusing

Yeah but the real magic is when you chain like five methods together lol

Wish they'd show an example here, the docs are too dry for me.

Whisper 随想笔记

Wait, so if I just write some functions in a file, I can import them anywhere? Cool.

“Even though the slice header is passed by value”

Whisper 随想笔记

This is exactly why slices feel like references even though they're not.
