sr-latchon It's just a virus, the E.R. told him – days later, he was dead

2-3% error is too high, this is something we _should_ be scrutinizing, and healthcare _should_ be more expensive if the reason it's expensive is that we're pouring more resources into it to get diminishing returns on reducing mistakes.

Costly healthcare due to scrutiny is not the problem with healthcare in the US. The problem is drug monopolies, medical (mal)practice without a license by insurance companies, and the lack of taxpayer funded healthcare-as-a-right.

We need to create an environment where someone like Terblanche feels comfortable advocating for himself without feeling like he's being a burden on the ER, and physicians don't feel like they're wasting time by investigating seemingly trivial cases. Such a situation exists because we are not pouring enough money into healthcare in this country.

the way i see it, before these tools, only someone with a lot of resources (or skills) could track down a location from a picture. now, anyone can do it.

the best case outcome is people become more aware of the privacy implications of posting photos online

Does it have internet access? Looks like a very convenient interface for looking for hotels, planning travels

sr-latchon RP2040 Project Template

This is the project template I use for the RP2040. Removes the hassle of setting up `pico-sdk`, as it just clones it in the `Makefile`.

Easy to add other dependencies such as FreeRTOS, just add it to the Makefile and include it in the CMakeLists.txt

Derived from the work I did at Purdue Space Program (https://sagarpatil.me/projects/cms-avi-sw)

sr-latchon Show HN: We made a small and cheap network switch

Ok this is sick, I love the philosophy of your team. I'll be strongly considering your CM4 carrier and ESC to integrate into future designs.

Also thank you, I've loved working on the PSP rocket! Bi-propellant rocketry is a pretty rare to do as an undergraduate, and you should consider applying to these schools if that's something that motivates you:

- Purdue: https://purdueseds.space/

- Berkeley: https://www.berkeleyse.org/

- UCLA: https://www.rocketproject.seas.ucla.edu/

- Georgia Tech: https://www.gtspaceprogram.com/

- ERAU: https://daytonabeach.erau.edu/about/labs/rocket-laboratory

This is a non-exhaustive list of schools I know that have undergraduate-run liquid rocketry programs.

sr-latchon Show HN: We made a small and cheap network switch

Awesome work! It's really cool to see this from a high school team. While designing liquid rocket avionics [1] at Purdue Space Program, we went with a BotBlox switch that cost $80 apiece [2], which I thought was ridiculous. My proposal to in-house the Ethernet switch was vetoed because I was a filthy CS student (joke) and my co-lead (the electronics guy) said it wasn't worth our time designing and validating such a part.

An Ethernet switch for $6.9 directly from JLCPCB is pretty incredible, thank you for making this product sector a tiny bit better :)

sr-latchon AMD's "Peano" – An LLVM Compiler for Ryzen AI NPUs

If you've taken a compilers course, it's pretty similar to register allocation. You want to make sure you're using as much of the processor as possible.

sr-latchon Building a rocket engine from scratch

This is absolutely not true - injector design is the most important aspect of designing a thrust chamber. Poor mixing of propellants leads to severe combustion instability, which often leads to explosions. Even the earliest space programs did significant testing on propellant choices and injector designs (see Ignition! by John D. Clark)

Also, pressure fed rockets have always been a fairly terrible design. Pressure feeding requires heavy tanks, and incurs a big mass fraction (dry mass / wet mass) penalty. Outside of rare cases, it's only used for ground testing.

sr-latchon MRSK: Deploy web apps anywhere

I find Docker running a full Linux userspace a little bloated. Thankfully there are distroless base images(https://github.com/GoogleContainerTools/distroless). Haven't done service dev in a while, so I don't really have experience with this, but it looks promising.

I have a universal benchmark for judging how much knowledge a language model stores, and it's asking about the G-FOLD paper (https://www.lpi.usra.edu/meetings/marsconcepts2012/pdf/4193....), because I noticed GPT-3.5 hallucinates when asked about it, whereas GPT-4 is capable of providing a high-level overview.
