I'm impressed with Claude Design. I see its disruption starting with smaller teams. As a founder I find myself turning to it more and more for the convenience of one-off design tasks. Sure, it's super slow, and one-shot quality is not quite there, and its image capabilities suck, but using it in between multi-tasking other things, it's helping me move faster.

One pattern I find useful for working with LLMs is a nice long ramble session. Sometimes the LLM needs more bits to understand what you're trying to achieve, but you're too lazy to type them. In these cases I like to lean back, switch to /voice and just ramble for like 10 minutes, total mess, anything goes, full stream of consciousness. Sometimes I declare it up top, something like "switching to speech recognition sorry for any typos...". Sometimes I turn it into a small interview of a few turns.

Exciting PlasticList update: We were honored to work with @bobaguys to identify and eliminate the sources of BPA contamination, and their teas are now BPA-free! They have fully transitioned to BPA-free receipt paper, which PlasticList confirmed to be BPA-free through independent lab testing. They have also switched to brown sugar in BPA-free packaging. We have been impressed with their commitment to get to the bottom of the issue and move fast to remove BPA from their supply chain. If you want healthy and delicious tea, I highly recommend Boba Guys! Quoting @natfriedman Advice for Food Companies Since we launched PlasticList, we’ve been heartened to have quite a few food companies reach out and ask for help interpreting their results and tracking down and eliminating their contamination. I’ve had calls with a bunch of these. I am happy to report that no food compa… Related

I am so sorry. I shouldn’t let this stuff get to me, but it clearly did, and I took it out on DHH, who, while I disagree with him on several points, isn’t the actual villain in this story: it’s WP Engine and Silver Lake.

Their words
So most people, when they advertise new context window increase, they talk a lot about finding the needle in the haystack sort of evaluation metrics and less about whether there’s any degradation in the instruction following performance. So I think that’s where you need to make sure that throwing more information at a model doesn’t actually make it more confused.

I am slowly trying to figure out Nix/NixOS. I just realized something I'm very confused by: Is it really the case “pinning’ in NixOS prototypically means “pinning a single version of the entire package repository, and then pulling in whatever versions it contains”? I mean, "it's all just code" and it seems to be *possible* to mix and match via `fetchTarball`. But is pinning the universe as-a-unit really the normal pattern? Nix Related

It is rare that a sports book captures my attention, rarer still when a sports autobiography does. But “Open” delivers a compelling life story superbly told by an athlete. Desire, motivation, and competitive drive him to the the highest levels of professional tennis, but he loses his interest, and was so often unhappy, confused and unfulfilled by his achievements. As an autobiography, it is bluntly honest, sometimes painful, but most of all a fascinating compelling read.

At first glance the Fastball struck me as a humble offering, but it quickly grew on me. Mostly after I started to carry and use it. I wasn't immediately impressed when I pulled the Fastball from it's box, and as a collectible I'd probably pass. But as a user piece I can easily recommend it.

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.
