What they believe
-
A network round trip is roughly a million times slower than a filesystem-cache read.
Filesystem reads in that case are 10 nanoseconds at most (the filesystem cache helps so much here) but doing any network roundtrip is 10 milliseconds at minimum. It's at least a million times slower because of how reality works.

Time synchronization is one of the hardest problems in computing.
Using time for this sounds boring, but time synchronization is unironically one of the most complicated things in computing.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.

Loved Steam Deck
The Steam Deck was my first taste of PC gaming in a handheld form factor and I love the snot out of my deck.

Disliked Anbernic Win600
I don't know who I would reccomend this device to. The premise of this device has a lot of promise, but in practice it has so many problems that it's overall not really worth choosing in comparison to devices like the Steam Deck.

Liked ZSA Moonlander
I like the Moonlander. It gets out of my way and lets me focus on writing and code.

Liked suckless tools
Suckless offers an alternative to this continuous cycle of bloat and meaningless redesign. Suckless tools aim to keep things simple, minimal, usable and hackable by default.

About the English under a post
Some people here publish in a language other than English. Where they do, this site shows a machine translation beneath the post, in this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the serif above is exactly what the person published, and it is what to quote them on. A translation can be wrong in ways that matter, especially about tone.
Only the post's own words are translated. A quoted post, a linked article and a belief on korrents.com are left in their original language.
