Thanks! If you get a chance to try it outside, the GPS lock is usually pretty fast. Would love to hear how it works for you — especially if anything feels off or missing. I don't have analytics so user feedback is the only way I know w

This is the natural consequence of building everything around "the agent needs access to everything to be useful." The more capabilities you hand an agent, the larger the attack surface when it encounters a malicious page. The sim

That tracks. The defense primes have zero incentive to make things cheaper — their business model is cost-plus. A guy building something for 10k in his garage is an existential threat to programs billing 500k per unit. Of course they ignore

From what I've seen, the teams that are actually on the fireline mostly use paper ICS 214s and radio. The structured digital stuff lives at the ICP/EOC level. So the gap is really between field collection and the management system

Visual SLAM on a rocket would be wild. The frame rates you'd need at those velocities are brutal though — feature tracking falls apart fast when your entire visual field is changing at hundreds of m/s. Drones are the sweet spot wh

For a sub-minute flight the drift budget is actually pretty forgiving — a MEMS gyro drifts maybe 1-3 deg/sec, and if you're fusing with accelerometer data you really just need "which way is up" and "am I still point

I wrote the MGRS conversion from scratch using the DMA Technical Manual 8358.1 rather than pulling in a library. The trickiest part was handling the Norway/Svalbard UTM zone exceptions and getting the 100km square letter cycling right.

I wonder what could have possibly sparked that... lol

The AI slop problem is real and getting worse. Half the "community engagement" you see now is LLM generated comments that add nothing. It actually makes genuine participation more valuable though, because people can tell the diffe

Jax basically gives you the array language without leaving Python, and the XLA backend means you're not hand-tuning C for the GPU path. The numpy interface limitation is real though and once you need something that doesn't map cle

The engineering is genuinely impressive for $96, but naming the repo "MANPADS-System-Launcher-and-Rocket" on GitHub is going to attract exactly the kind of attention you don't want. ITAR implications aside, the interesting pa

Had no idea about that, went down a rabbit hole researching it. It's a pattern that keeps repeating: by the time mil-spec hardware ships, the commercial equivalent is two generations ahead.

That's valid and definitely changes the risk profile if the military constellation is operationally separate. Though the civilian network is still a force multiplier in many cases, which puts it in the targeting calculus for adversarie

You're right that the launch cost gap is the real barrier. Europe's been talking about sovereign launch capability for years but Ariane 6 still can't compete on cost with SpaceX. I think the more likely path is that smaller n

This is just dynamic pricing with extra steps. Airlines have done this for decades but at least they're transparent about it. The difference here is that readers don't know the person next to them is paying a different price for t

The long lists of "places to post your launch" are less useful than people think. I've had way better results from just hanging out in communities where my users already are and actually participating in discussions over week

The name "Right to Compute" implies this protects individual users, but the actual text reads more like a shield for datacenter operators against local zoning and environmental review. Worth reading the bill itself (SB 212) before

Smart approach with the key wrapping. Re-encrypting every note on a password change would be brutal at scale. Do you have a recovery path if someone forgets their password, or is it truly zero-knowledge where the data is just gone?

That's the part that makes allied nations nervous. If you're running military comms through Starlink and the US decides to play hardball in some trade dispute, your entire C2 network just became a bargaining chip. Ukraine showed h

Fair point on single-sourcing, but the difference is that Lockheed doesn't have a consumer business that creates geopolitical incidents on Twitter. Traditional defense contractors are purpose-built for that relationship. With Starlink,

In practice the ladder has two rungs for me. Write it in Python with numpy/scipy doing the heavy lifting, and if that's not enough, rewrite the hot path in C. The middle steps always felt like they added complexity without fully s

The biggest win for me with docs-in-repo isn't the AI angle, it's that pull requests can't land without updating the relevant docs. When your support pages, privacy policy, and README all live in the same repo, they naturally

The dual-use problem with Starlink is really just the most visible version of something happening across the military. Phones with civilian GPS chips are increasingly used alongside dedicated mil-spec hardware, simply because the commercial

The read-only past is a really smart design choice. I build local-first apps and it's always tempting to add edit-everything flexibility, but constraints like this are what keep a tool focused and actually useful. How does the Supabase

Refreshing to see some competition to the US AI scene. It's been the same three models trying to one up each other by copying and tweaking rather than pushing true innovation
