I like so many things about this. Complementary to LLMs, not just another model, same interface. Do one thing, but do it well. Really hoping that it works well. typesafe.ai

It all co-evolved, each internalizing the interface with the other, in a particular history, which would not be the same if re-played, except for some convergence (ways to organize wholes and parts tend to rhyme). But, it didn't have to be "tickets." Now, the relationships self-sustain. Qwerty.

I asked ChatGPT to summarize HN comments, somewhere in which someone quoted Dune and that killed ChatGPT. Was it the copyright (quote is fair use) or the content that ChatGPT found objectionable? 🤔

Overlapping work. For most things multiple people could reasonably contribute to the work and most of the time, multiple people are working toward the same ends. (More of a team signal than engineering discipline, perhaps?)

The interesting part is using automation to structure the ask for feedback to make it easier for humans to provide it.

The idea of maximizing automated feedback prior to human feedback seems to follow logically. www.lucasfcosta.com/blog/backpre...

"Feedback is all you need" feels like the central dogma for agents. Adding one word to the @simonwillison.net agent definition: "An LLM agent runs tools in a *feedback* loop to achieve a goal."

The trend can be inevitable, but specific winners and losers and how they win or lose may not be. In 1999, it was perhaps hard to see cloud computing business model (server software as free complement to rent compute), SaaS (renting software), web browsers as free complement to sell advertising.

Went to a talk on cookbooks and food from a queer perspective at @omnivorebooks.bsky.social tonight. What a cool and cute bookstore. Great talk. Ended up winning a gorgeous Smithy cast iron pan in the raffle. How appropriate since cooking is my love language and my boyfriend's love is pancakes.

I'm fascinated by the Claude Code leak. A low impact, easily reversible micro decision was also a high impact, irreversible macro decision. I have questions. What did that decision process look like? Where does accountability lie and what does it look like? Eagerly awaiting a public post-mortem.

In the 90s I worked for a company ($1B/yr) that built their own ERP rather than buying. Cost was 1/10th and results were better because the software adapted to the (strong) business vision rather than forcing the business to adapt to the software. www.youtube.com/watch?v=cUbI...

One definition of Software Architecture is "The parts that are hard to change." Transitioning from "hard to change" to "easy to change" is a major advancement. Perhaps we're seeing a new configuration of what is Architecture and what is not? React: Architecture no more? (When enabled by tests?)

Confusing outcomes with output. And boy are LLMs good at output. So enticing to focus on tools and process right now rather than outcomes because the tools are so rough, but also so promising.

Love it. I used to tell people I was a magazine columnist and get into the most amazing conversations despite the fact I wrote about software engineering. When I would tell lay-people I was a software engineer, conversations always devolved to "Can you fix my broken windows machine?"

No expert on carpal, but after decades of keyboarding, started having hand issues. Took a while to figure out ... swapping a rectangular table for oval in the kitchen combined with WFH laptop. Straight table = no problem; curved table = hand pain. Took six months to heal up once I realized.

Based on experience, I believe the captions on these photos have been reversed in this version of @buzzfeed.com's daily "98 vaguely thematic things we hope you will buy" listicle.

Self-confirming bias. After a while all your best employees would love blue, it's what they all have in common, so clearly that's what you should look for. (All your worst employees would love blue, too, but maybe those are just the ones that deep in their hearts didn't love blue enough?)

The types of questions you ask in an interview creates a signal. I would react negatively to a personality test. Do you really want to only hire people who have a positive reaction to personality tests? What if your process was to ask people what their favorite color is and then only hire "blue?"

SF Gate reported an estimate of as many as 100,000. SF Standard reported 50,000. I haven’t heard anything official. For comparison 50,000 marched in the 2024 SF pride and one million attended. 100,000 were in the women’s march in 2017.

Published recipes have become more precise over the years. Older recipes presume the reader has more experience. But coleslaw is not baking, precision is unnecessary, a flaw even. The less experienced the cook, the less likely they are to own a scale. What does 10g of carrot look like? New problem.

Some people’s primary experience of remote is the most extreme and difficult form. For example with team members in SF and India there is a maximal distance, maximal time difference, plus cultural or possibly language differences. Three orders of magnitude harder for communication.

“Two positive non-work interactions per week” is minimum to build trust. Forgot where I heard this, but I’ve used this guideline for a long time. In-person, this comes for free. Remote, you have to deliberately engineer these interactions. Doing this authentically is a learnable management skill.

One problem with the Viable System Model is that every article has to use 80% of its word budget to re-explain it, badly. Language like “system 3*” and “algedonic” creates a low r0 meme-deficiency. Is the lack of accessible pedagogy a fundamental property of the VSM or can it be overcome?

And that’s how the board of our HOA operates. Tried to move to Google sheets. people kept asking, “which version of the sheet is this?” I’m like “the newest one, it’s always the newest one. That’s the point.” They also print out web pages and sheets and pass them around at meetings.
