Programmer, writer and musician; author of the Learn Code the Hard Way books and of Mongrel, the Ruby web server.
Video Compression Idea: Existing compression algorithm with an attached sequence of upscalers. Compress it at 720p and then choose/tune upscaler settings at varying boundaries to scale it up to different sizes without or minimal distortion. Related

How large is Snowflake's AI revenue? Management lowered product gross margin guidance from 76% → 74% due to "fast-growing AI workloads." If GPU inference runs at ~25%–35% gross margins, that 200 bps compression implies ~$60M–$75M/quarter (~$240M–$300M ARR) in direct AI token consumption. Related

Co-founder of Superlogical, started in 2026 to build server-side terminal infrastructure; creator of Ghostty. Co-founded HashiCorp and created Vagrant and Terraform before that.
A video explaining a handful of the tricks we use to optimize for memory within the Superlogical server: in-memory compression, moving file descriptors between event-driven and blocked threads dynamically, full terminal state binary snapshot/restore in microseconds, and more! Related

Designer and engineer; formerly principal research engineer at GitHub Next; writes at wattenberger.com.
"generative AI" puts the focus in the wrong place. what I think is actually the new superpower is * translation * between languages, but also between mediums. sketch <> figma design <> code <> image also, they do an inverted form of lossy compression: input + priors = input inflated with understanding of the world we're so focused on changing the input, but swapping out the priors is interesting as well what happens when we intentionally replace the priors with a different mindset / a different culture? can we trick ourselves into a rubber hand illusion, but for experiencing the world as some… Related

Founding member of OpenAI and former director of AI at Tesla; creator of nanoGPT and the term "vibe coding".
Their words
Um so I almost feel like because the internet is so terrible, we actually have to sort of like build really big models to compress all that. Uh most of that compression is memory work instead of like cognitive work. But what we really want is the cognitive part actually delete the memory

Astrobiologist and theoretical physicist at Arizona State University, working on assembly theory and the physics of life.
Their words
And there’s still a lot of impetus in the physics community to think that non-equilibrium physics will explain life. But I think that’s not the right approach. I don’t think ultimately the solution to what life is there, and I don’t really think entropy has much to do with it unless it’s entirely reformulated.

Theoretical physicist and philosopher, Homewood Professor of Natural Philosophy at Johns Hopkins and fractal faculty at the Santa Fe Institute. Writes the Preposterous Universe blog and hosts the Mindscape podcast.
Their words
Sometimes people think that complexity or life or whatever is fighting against the second law of thermodynamics, fighting against the increase of entropy. That is precisely the wrong way to think about it. We are surfers riding the wave of increasing entropy. We rely on increasing entropy to survive.

Software engineer who writes the blog Made of Bugs about performance, debugging and understanding computer systems. Previously worked at Anthropic on interpretability, at Stripe on Sorbet, and at Ksplice.
(De)compression is conceptually quite straightforward: The decompression algorithm specifies a weird domain-specific VM, and the compressor is simply an automated code golfer for that architecture. Related

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.
