Why were people so incredibly wordy back then?

It's not an optimization if it pessimizes almost all usage by adding a check for the dunder

The only other reasonable explanation would be that he has consumed so much LLM content that the machine has erased his voice and replaced it with its own.

Yes, that's the point where I was like "wait a second" and started counting em dashes. A third alternative, perhaps the LLMs were trained hard on his prior work? :-)

I wish they would just explain it in normal terms instead of this nasty LLM "engaging blog post" style

I thought the author might just be heavily influenced by the LLM style, but when there are also complete non sequiteurs like

> Low frequencies take very few bits to encode, and you feel them as much as hear them

yeah then it starts to smell pretty bad.

The diff of the linked commit in git is completely trivial, clearly it just got tagged because of the signoff in the commit message: https://github.com/git/git/commit/d7971544fe17378f44f4998301...

I would be surprised if there is no LLM-assisted code in there prior to this commit, this is just the first where the author chose to disclose it.

Several and a few are the same number, they only differ rhetorically.

Presumably there is an antialiasing low pass filter somewhere before JS gets to the data. I have a similar sample rate and it certainly didn't work at all for me.

What do you mean by cycles? A ripple-carry adder needs to wait for the carry bits to ripple through yes, but there's no clock cycle involved.

The JSON types are string, number, boolean, null, object and array. So how could the suggested code possibly work? Do you want JSON.parse to do arbitrary code execution like Python's pickle?

Bitbucket is okay to use, the main problem like with every Atlassian product is that it is dog slow.

You definitely need discipline to use C++ in embedded. There are exactly 2 features that come to mind, which makes it worth it for me: 1) replacing complex macros or duplicated code with simple templates, and 2) RAII for critical sections or other kinds of locks.
