The loser has more in common with the winner than with the person sitting on the sidelines. The winner and the loser each had the courage to try. Both risked embarrassment. Both were willing to face uncertainty. Both were stubborn enough to continue. Success is endurance in disguise. It belongs to the person who can absorb the losses without absorbing the identity of "loser." It's the courage to start — and to stick with it — that is the real separator.

If anyone wants a nice side project... The fast number parsing fast_float (part of GCC, and other important systems like MySQL) is not always exact when dealing with 16-bit float parsing (specifically float16_t). That is, some number strings can lie in between two numbers and the rounding is wrong. In fact, nobody has done a proper analysis of the implementation to insure that it is correct. Yeah. I could ask my AI, but it is still work, especially because I do not trust anyone, not even an AI, to get it correct the first time around. Contributions invited. github.com

7 Films I Love: 1. Perfect Days. Can you find enlightenment from cleaning toilets? After watching this Tokyo-based film, you might well think so. Perfect Days is beautifully shot and earned lead actor Kōji Yakusho (Shall We Dance) the Best Actor Award at the 76th Cannes Film Festival. 2. The Wild Robot. This is a family-friendly, “This is so cheesy! Why am I crying?!” type of feel-good watch. This film was adapted from the #1 New York Times bestselling illustrated middle-grade novel The Wild Robot by Peter Brown. 3. Argentina, 1985. I absolutely loved this film.

Lazy work used to mean too little output. Now, with AI, it often means too much and more work for everyone else. @tobi call it "slop grenades." A "Slop Grenade" is when you let AI produce the work and pass it on without adding any value (including checking it). Someone else has to wade through it, catch the mistakes, and clean up the mess.

Nothing matches. Show everything
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.

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.
