sounding rockets & bad computer programming

they’re worsening the problem technically but it really is an issue of the farms.
This is why they say the DCs aren't "polluting" the water, they're "worsening" a pollution problem. But even this is silly. It looks like Amazon's wastewater is only around ~0.7% of the Port's total volume, so the concentrated water gets diluted into the other 99.3%. The impact is negligible.

never kill the Detective Raphaël Ambrosius Costeau in your head, his advice is impeccable and he would never lead you astray

really breaks my heart that these assholes are using my favorite technologies (Rust, Haskell, and Nix) to build third rate General Atomics knockoffs in service of fascism

i’ve had dnscrypt proxy fail to come up after a power cycle when i used Quad9 as my resolver because it was fucked for one reason or another.

i think, in NoVA especially, it’s a deliberate choice to maintain the fiction so people can hook up without having to deal with tough conversations

i’m kind of a hater but that’s how SF always feels to me.
November 23, 2025 at 4:16 AM
this is still wild to me tbh.

i don’t understand how Twitter is that sticky for group chats, like i get that it’s a pain to get people from social media onto Signal or whatever but come on.

SF is weird like that, the whole city shuts down way earlier in the day than i’m used to.

also this being the weekend before thanksgiving means that there are probably a bunch of people who are flying/driving back to see family.

fuck off man i know how much work you put into helping your sister with all this, she wouldn’t be doing this without you.

one thing i’m curious about is whether SpaceX has much of a war chest, or if they plowed the Falcon 9 profits directly into Starship R&D.

as soon as there is any competition in reusable LEO and/or satellite internet they’re going to be in a race to the bottom.

it only works with domain-specific engineering tasks, the broader point i’m trying to make here is that if you want to develop a product that uses LLMs as a natural language interface on the frontend and LLMs for execution on the backend then you need some sort of firewall in between the two.
November 21, 2025 at 5:37 PM
tongue somewhat in cheek, if you use that intermediate representation as a separation layer to drive other LLMs then you have to do Different Real Software Engineering, but still it’s frustrating that this seems to be under-discussed in the industry vs. ”MCP app the things!!”
November 20, 2025 at 8:39 PM
prompt injection is de facto “solvable” by using the LLM as a natural language interface to some intermediate representation for commands except then you have to actually do Real Software Engineering (aka your fucking job) and everyone apparently thinks that’s too hard now

very common to design & verify controls in simulink, then generate code (MISRA C) from those models

buddy i have some absolutely tragic news for you about pretty much any airplane software produced in the last 15 years (at least)
