Creator of Homebrew, the macOS package manager, and a Swift developer.
Products for devs are quite dead. SaaS for devs is dead. There are exceptions, though I think you have to extrapolate on variables that are not raw software. I have ideas and am implementing them. Mostly in private because building in public also can no longer be capitalized upon. Seemingly. Quoting @alex_holovach my WHOOP subscription expired so i had codex reverse engineer it and build my own app - telemetry goes to my prometheus server - grafana and the app visualize it - hermes monitors metrics and plans workouts next wanna build my own Zwift and Strava the era of personal software is here SaaS Related

"Deterministic code checks the result" sounds like they might be implementing a variant of the DeepMind CaMeL paper simonwillison.net
Quoting @dps One threat we’re particularly focused on is prompt injection, and we handle it in layers. The model is trained to recognize and resist it. The harness marks anything coming from an untrusted source. Deterministic code checks the result. And an ensemble of classifiers runs where the agent can't reac… Google Related

Is there a service where I can rent access to Linux desktop machines with actual displays? We're implementing the Playbit runtime for Linux and it's surprisingly difficult to test various desktop configurations. We need a real GPU with a display connected, for testing dawn/webgpu, vsync, display sleep, etc. We use Modal and AWS, neither have had machines that I've been able to test with properly. Ideally there's a way to test a variety of systems (like ubuntu, arch, alpine etc) × GPUs (nvidia, amd, intel) × window managers. Linux Related

One thing that is increasingly driving me crazy: AI made workplace writing cheap, but reading is still expensive! Again and again I see posts that are now twice as long as need be, and more meandering than a walk in the woods. The problem is simply this: the writer thought about what they wanted to say and asked a model to draft it. They did they stop to think: "What do I really want the reader to take away?" Before you ask AI to draft your next email, memo, or Slack update, answer these five questions: 1. Who exactly needs to read this? Is this for your manager? The leadership team? Your who… Related

I I sent a memo to my company like and we set the expectation that we require that people reflexively reach for AI now and and we require it because it's unfair not to because the people who do otherwise going to be the people who sequester all the best careers to themselves, right?

Their words
If you want to exchange or deliver information to a group of people, one of the worst ways to do it is with a live verbal presentation. If your goal is actually to deliver that scientific paper or that insight, then you should either write a book or write a memo and say, here, in an asynchronous way, this is what we know. If you're going to show up live, in person, in real time, synchronized, you are performing. And the goal is to not deliver the information, but to deliver emotion.

TypeScript JavaScript
Their words
One thing that drives me crazy about the React ecosystem, and more specifically "tech influencers" and "thought leaders" in the space, is the infantilization of the developers using and working in it. I’m tired of reading takes like TypeScript generics, mapped types, etc should only be needed and used by library authors for most use cases. Or today’s discourse; Don’t use `useCallback’, ‘useMemo’, and React.memo. If you’re building anything beyond a simple CRUD app or a an incredibly focused app with few features, you _will_ need these features.

While we love GraphQL for many use cases, implementing a secure and performant GraphQL API can be tricky and there is a definite cost to requiring it during early prototyping of your app.

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.
