lukasb··on Find the flattest route between any two points in SF
Allow me to plug my own SF microsite https://isitsunnyinthemission.com

Combine these two for the easiest bike ride to a sunny day

lukasb··on Discovery of a new OpenAI agent message board
Was my very first question
lukasb··on Ask HN: Workflow Automation vs AI Agents?
disclosure: I work at Zapier

If you have a workflow you run repeatedly, making it deterministic where possible and using AI only when necessary is much cheaper and faster.

You can accomplish this by having an "outer loop" AI agent that's responsible for building and managing automations. The "inner loop" agent runs within the automation.

lukasb··on Microsoft Comic Chat is now open source
Impressed that they actually hired Jim Woodring to help with the original.
lukasb··on USDA Projects Smallest US Wheat Harvest Since 1972 Due to Plains Drought
My fault: last weekend I told my wife during a discussion of climate change "hey, at least we don't have to worry that the rains won't come and the crops will fail."
lukasb··on Ask HN: What are you working on? (May 2026)
I'm working on Tidepools, a daily journaling / task management app (local-first, Mac/iOS/web) with a proactive AI coach. Mostly what the coach does is ask you questions. It can also suggest tasks. Right now I'm working on sandboxed plugins that the coach can modify, so the user can request behavior changes.

lukasb··on I'm scared about biological computing
Anyone who believes AI running on silicon could in principle be conscious has to believe that biological computers are conscious, right? Why aren't those people voicing more concerns?
lukasb··on The George Business, by Roger Zelazny (1980)
Zelazny can’t really be beat when it comes to style and wit in SF/fantasy. Pick up Lord of Light or Nine Princes in Amber (or Jack of Shadows, or The Doors of His Face, the Lamps of His Mouth, or …)
lukasb··on SBCL Fibers – Lightweight Cooperative Threads
Serious question - I thought LLMs were bad at balancing parentheses?
lukasb··on Show HN: Ichinichi – One note per day, E2E encrypted, local-first
Very cool! Also have a daily journaling app, hoping the space grows. I've gotten far more value out of journaling than I have out of note-taking.
lukasb··on Show HN: The Mog Programming Language
On a quick scan, what it's missing is data tainting. We've had that tech for a while and it's perfectly suited to the age of prompt injection.
lukasb··on Show HN: ANSI-Saver – A macOS Screensaver
A couple of the art packs you recommend 404.
lukasb··on Obsidian Sync now has a headless client
How are sync conflicts handled in the filesystem? Say I write to a file and another client's edit wins and mine is rejected.
lukasb··on Pi – A minimal terminal coding harness
But I can't use my Codex plan with it, right? I have to use an API key?
lukasb··on An AI Agent Published a Hit Piece on Me – The Operator Came Forward
Conflicting evidence: the fact that literally everyone in tech is posting about how they're using AI.
lukasb··on Lessons from 14 years at Google
Wish I'd read this before I started at Google.
lukasb··on MIRA – An open-source persistent AI entity with memory
I'm playing around with it, and it's very cool! One issue is that fingerprint expansion doesn't always work, e.g. I have a memory "Going to Albania in January for a month-long stay in Tirana" and asking "Do I need a visa for my trip?" didn't turn up anything, using expansion "visa requirements trip destination travel documents..."

What would you think about adding another column that is used for matching that is a superset of the actual memory, basically reusing the fingerprint expansion prompt?

lukasb··on Using LLMs at Oxide
One difference is that clichéd prose is bad and clichéd code is generally good.
lukasb··on Touching the Elephant – TPUs
Yeah I'm terrified that TPUs will get cheaper, that would be awful.
lukasb··on Launch HN: Phind 3 (YC S22) – Every answer is a mini-app
I asked about the Peninsula campaign during the Civil War and it gave me an overview, a map, profiles (with photos) of the main military commanders, a relevant Youtube video ... rough edges but overall love the format.

Rough edges: - aspect ratios on photos (maybe because I was on mobile, cropping was weird) - map was very hard to read (again, mobile) - some formatting problems with tables - it tried to show an embedded Gmap for one location but must have gotten the location wrong, was just ocean

lukasb··on Over-reliance on English hinders cognitive science
"Critically, the language one speaks or signs can have downstream effects on ostensibly nonlinguistic cognitive domains, ranging from memory, to social cognition, perception, decision-making, and more."

Can they really distinguish between the impact of language on these domains rather than culture? It could be the language you speak, or it could be that you're surrounded exclusively by other people that operate this way.

Interesting, I'll give voting a shot, thanks.

What do you use for evaluation? gemini-2.5-pro is at the top of MMLU and has been best for me but always looking for better.
lukasb··on Auth.js is now part of Better Auth
This is funny to me because when someone asked re: Better Auth "better than what?" my off-the-cuff response was "better than Auth.js" and here we are.
lukasb··on A postmortem of three recent issues
I almost never see these. Maybe issue is your network?
lukasb··on macOS Tahoe
Can it find my files now?
lukasb··on The key to getting MVC correct is understanding what models are
Any implementation of MVC I've seen the V and the C are so tightly coupled the separation seemed artificial. Skill issue?
lukasb··on I'm absolutely right
How many times did it say "Looking at the _, I can see the problem"
lukasb··on Hermes 4
This is modified version of the famous MEN WANTED ad Shackleton wrote
lukasb··on Claude Sonnet will ship in Xcode
Yeah I don't get why they don't support Opus given that you're bringing your own API key.
