Fair point on open models + EU hosting, that's a much better option than I gave it credit for. I was thinking more about the "just plug in an API key and go" experience where OpenAI/Anthropic are still way ahead, but yeah if you're willing to do the work the gap is closing fast.

Good list but the biggest missing piece for most new SaaS products right now is AI/LLM APIs. If you're building anything with AI features you're calling OpenAI, Anthropic, or similar - all US. Mistral exists but the ecosystem around it is much thinner. That's probably the hardest US dependency to drop in 2026 that I can think of.

Plausible is a great pick though, been using it and it covers most of what you'd want from analytics unless you need GA/GTM tied to ad campaigns.

The fact that they deliberately manufacture the satellite clocks to tick at the wrong frequency on the ground (10.22999999543 MHz instead of 10.23 MHz) so that relativity makes them tick correctly in orbit is one of my favorite engineering details in any system.

New comment by dmk in "Bitcoin miners are losing on every coin produced as difficulty drops"

The headline is dramatic but this is literally how bitcoin is designed to work. Miners leave, difficulty drops, costs go down, mining becomes profitable again. The interesting part isn’t the loss per coin, it’s how long the lag between unprofitable mining and difficulty adjustment keeps forced selling pressure on the market.

New comment by dmk in "How NASA built Artemis II’s fault-tolerant computer"

The quote from the CMU guy about modern Agile and DevOps approaches challenging architectural discipline is a nice way of saying most of us have completely forgotten how to build deterministic systems. Time-triggered Ethernet with strict frame scheduling feels like it's from a parallel universe compared to how we ship software now.

Show HN: Artemis.fyi - Real-time tracker for the Artemis II Moon mission

dmk — Sat, 04 Apr 2026 22:48:42 +0000

There are plenty of Artemis II trackers out there. I looked at a bunch and kept running into the same issues - some had data that didn't look right, it was hard to use on smaller screen, others felt overly complicated for what I actually wanted to know: what's the crew doing, where is Orion, how fast is it going. The best one I found was issinfo.net/artemis, which inspired a lot of the design.

So I built my own. The part that was genuinely interesting to me was the data. Turns out anyone can query JPL's Horizons API for full ephemeris data on the Orion spacecraft - position, velocity, range - for free. I had no idea this existed.

Even better: NASA's Deep Space Network publishes a live XML feed (eyes.nasa.gov/dsn/data/dsn.xml) that updates every 5 seconds showing exactly which ground antennas are talking to which spacecraft. Right now two dishes in Canberra are locked onto Orion - one sending commands, both receiving 6 Mbps of S-band telemetry at 296,000 km. You can see Juno at Jupiter, JWST, Mars Odyssey, all in the same feed. It's pretty amazing what's just sitting there in the open.

The app fetches trajectory from Horizons, crew activities from NASA's published flight plan, and live ground station status from DSN. I'll be honest - it's mostly vibe-coded with supervision. The data pipeline is the part that was more manual: figuring out what's publicly available, how to compute relative positions from raw vectors, how to cache and backfill. That was the fun part.

Code is open on GitHub. I built it for myself and as a fun exercise, but happy for any feedback - especially around data correctness and what other public data sources are out there that I might be missing.

Sure, but the study is saying something slightly different, it's not that people write bad prompts for artifacts, they actually write better ones (more specific, more examples, clearer goals,...). They just stop evaluating the result. So the input quality goes up but the quality control goes down.

So I guess the key takeaway is basically that the better Claude gets at producing polished output, the less users bother questioning it. They found that artifact conversations have lower rates of fact-checking and reasoning challenges across the board. That's kind of an uncomfortable loop for a company selling increasingly capable models.

New comment by dmk in "Eight more months of agents"

dmk — Mon, 09 Feb 2026 19:19:54 +0000

The real insight buried in here is "build what programmers love and everyone will follow." If every user has an agent that can write code against your product, your API docs become your actual product. That's a massive shift.

The "start over in an hour" philosophy is underrated. I've been running my own infrastructure for years and the single most empowering thing isn't the setup, it's the peace of mind that you can just nuke it and spin up somewhere else.

Knowing that, I started looking at every SaaS subscription very differently.

Yeah, just had to upgrade to Max 20x yesterday because of hitting the limits every day and the extra usage gets expensive very fast.

dmk — Thu, 05 Feb 2026 18:00:43 +0000

The benchmarks are cool and all but 1M context on an Opus-class model is the real headline here imo. Has anyone actually pushed it to the limit yet? Long context has historically been one of those "works great in the demo" situations.

New comment by dmk in "Europe could 'weaponize' $10T of US assets over Greenland"

dmk — Tue, 20 Jan 2026 16:05:08 +0000

Fair point. Though I wonder if individual fund moves actually move the needle here or if it's mostly symbolic until it becomes a trend.

Living in the EU, I'm skeptical any of this happens. Our leaders have been pretty reluctant to push back on anything so far and most of these assets are private anyway.

Hi Troy, just wanted to let you know that I just sent you an email! :)

Also, just to be sure, I sent it to on-board.ai domain as well, as that seemed like the correct website (onboard.ai just showed "for sale" page). Might help some others too.

Wow, looks amazing, will definitely apply!

Just FYI, the link next to the Founding Engineer is leading to Founding Creator instead of the Founding Engineer: https://mitteai.notion.site/Founding-Engineer-254f3cdf01fb80....

Google login also seems to be having issues, multiple people reported to me that the login isn’t working and they’ve been logged out of their Google accounts.
