Artist and developer who makes esoteric software, games and tools aboard a sailboat as part of Hundred Rabbits with Rekka Bellum; creator of the Uxn virtual machine and the Orca livecoding environment.
I've been scratching my head trying to think how to package assets for my #lispGameJam project, I really REALLY wanted to be able to inline assets as raw hex code, like I normally do for uxn projects, not have to read binary files, so I added a special form with square brackets that lets me to just that! This is the first sprite(a little arrow) I was able to store in my source code. Related

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.

Genie Garage doors enabled caching on their API resulting in everyones garage door being shared with everyone else using the API Cache Ruins Everything Around Me Quoting @IAmArcIvanov @TheGenieCompany Your AlladinConnect is either breached or malfunctioning where users using API integration (in my case via HASS) are seeing garage doors of other people's accounts.

Fable 5.1 is a thoughtful collaborator, thinking hard about my requests, proactively patching my blindspots, and verifying the work's correct without being asked. And with cache reads now costing 75% less, to $0.25/M tokens, huge savings for long-running, agentic tasks! Quoting @claudeai We’re introducing Claude Fable 5.1 and Claude Mythos 5.1. They're the world’s most advanced models for coding and knowledge work. Related

That's a hell of a lot slower than knowing it in cognitive L1 cache. And you can have way more round trips in your brain than you can, you know, muttering through, you know, super whisper or typing it out or whatever.

Memory-level parallelism: AMD is the king When your program asks for memory that is not in cache, the processor has to go to RAM. That trip costs on the order of 100 nanoseconds. On a 3 GHz core, that is about 300 cycles of doing nothing. Memory latency has not…

This is a new paradigm for interacting with Claude that is significantly more "inline" with all the other human activity org-wide. Once you do all of the under the hood engineering work to make this "just work" (e.g. across tools, integrations, compute environments, memory, security, etc.), Claude basically joins the team in a seamless way - you can talk to it as you would talk to a person and it can help with a very large variety of workloads. Imo this is the 3rd major redesign of LLM UIUX. The first paradigm was that the LLM is a website you go to, the second was that it is an app you downl… Quoting @claudeai Introducing Claude Tag, a new way for teams to work with Claude.

yay for automatic prefix caching! just set a single cache control field at the top level of your request body. note that you do still need to structure your prompt templates to benefit from prefix caching though. 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.
