Ironically I used AI for this question, and what came out is 'Echo prompt' apparently it's a thing: repeating LLM instructions twice increases accuracy.

Another idea was Chain of Thought leakage. It's like as if a chef saying "Now I am adding salt because the customer requested so"

Wrapper is really helpful for every time you do pacman update for official repo, you should recompile all of the AUR repo as well, otherwise you'll be in the land of 'partial upgrades'. Some packages don't complaint too much, while others do

It does, but there's a y/n question of whether you want to see the patch

"一百二十一 dollar "

Definitely chinese.

In Japanese, they say 'hundred' instead of 'one hundred' "百二十一"

True. The only 'distributed' part of bluesky is in the PR. Otherwise there'd be more instances.

My mastodon account is not even on mastodon.social, because why would I, when I could have a home server closer to home

a bit misleading title.

x+y = ln(exp(x) * exp(y))

exp(a) = eml(a, 1) ln(a)=eml(1,eml(eml(1,a),1))

Plugging those in is an excercise to the reader

> Like addition

I'm perplexed to the claim that addition is cheaper than XOR, especially since addition is built upon XOR, am I missing anything? Is it javascript specific?

Well it no longer constrains the data in a fixed output length.

What good does certificate format do? Certainly won't make people not reuse it the same way.

> where the affected users might be surprised or alarmed to learn that it is possible to link these real-world identities.

I feel like it's obvious that ssh public keys publically identifies me, and if I don't want that, I can make different keys for different sites.

They don't want each vm to have different public IP

New comment by Charon77 in "Forget Flags and Scripts: Just Rename the File"

Charon77 — Wed, 18 Mar 2026 05:32:45 +0000

If the rename changes the entire behavior (see busybox comment) it makes sense. But defining multiple arguments? Now the author had to use -- in the file name where using space would do (and the OS splits it for you)

And good luck trying to run the same programs with different arguments. You'll have to take turns renaming the file, or create hardlinks just for ephemeral arguments.

It can be useful but there's time and place to do it.
