“Consecutive normal punches”

His roasts be literally disgusting. He’s off by 2x. Does that mean I only have to slap the chicken at about 2k mph to cook it like a normal person.

I keep reading about the “supply chain.” I will just leave this here. https://www.softwaremaxims.com/blog/not-a-supplier

Its worth adding, TikTok in China (it’s called something else, I’m blanking) is entirely controlled on the state and there is absolutely no way that it would be permitted to host any political discussion or advocate mass action not approved by the state. Their “Hey call your congressman” stunt was the most idiotic PR move ever, because they demonstrated that this company is willing and able to leverage the userbase in the US in ways that would never be permitted in “West Taiwan”.

I’m still onboard with rust as being better than C, however…

My understanding is that it is considerably harder to correctly write unsafe rust than it is to correctly write c, because if you accidentally violate any of safe rust’s guaranteed invariants in an unsafe block, things go bananas.

It was confusing. It took me 3 tries to write the parser. The first time I didn’t realize there were multiple observations per game and the second time for some reason I was convinced the color came first.

Today in Zig

Spent most of the time running down annoying typos in the tokenizer.

I decided to learn zig this year. Usually I solve both parts in the same source file, but it was annoying so here part 1 and part 2

Modern optimizing compilers are magical. I would need to check assembly but I would actually expect the if to be hoisted out of the loop entirely to relieve pressure on the branch predictor.

Because it is a slow moving event that will unfold over the next century.

It cannot be both so incredibly anxiety causing and also lacking in any urgency at the population level simultaneously.

I’ve seen this before and I think it is worth adding some context too.

Let’s start with, yea, it leads to absurd result like the clown show in uvalde where I wouldn’t trust that police force to rescue cats from trees.

But… the other way you can’t have a right to a scarce resource (police protection). Police calls while not exactly random can’t be accurately predicted. It doesn’t make sense for a police force to be liable for failing to protect when they might literally not have the ability to protect. Or, through chance, there are no police officers that can get to the location in time.

Instead, the point is to rely on the police wanting to actually do their job and have a legal doctrine accordingly. But in our culture it seems that perhaps that is not necessarily a warranted assumption anymore.

It does. I use this port

You need to me careful about benchmarking to find performance problems after the fact. You can get stuck in a local maxima where there is no particular cost center buts it’s all just slow.

If performance specifically is a goal there should probably at least be a theory of how it will be achieved and then that can be refined with benchmarks and profiling.

I can’t remember exactly what all the pieces are. However, I believe its a combination of

• cgroups: process isolation which is why you can see docker processes in ps/top/etc but you can’t for vms. I believe this is also what gets you the ability to run cross distro images since the isolation ensures the correct shared objects are loaded
• network namespaces: how they handle generating the isolated network stack per process
• some additional mount magic that I don’t know what its called.

My understanding is that all of the neat properties of docker are actuall part of the kernel, docker (and podman and other container runtimes) are mostly just packing them together to achieve the desired properties of “containers”.

I suspect they meant it runs natively in that it’s an aarch64 binary. It’s still running a VM under the hood because docker is really just a nice frontend to a bunch of Linux kernel features.

Its all fun and games until the email list doesn’t include the people its supposed to and I get a call on a text on Sunday morning because ‘Ahmahgad the etl pipeline hasn’t started!?!?!’
