The coding interview is dead, at least for my team at Anthropic. I've seen enough to know that it no longer provides signal. I removed it from loops this month.

I have a spicy, optimistic take - I think there's an opportunity for junior engineers: https://t.co/PVvpQCbQtK

He has 40k on youtube by the way, but almost none here. Probably the cleanest robotics work you will find

a couple weeks ago I posted about how bone grows into titanium implants because cells can't find the boundary

turns out there's a catch engineers have been trying to solve for years:

titanium is too stiff (~110 GPa vs spongy bone's 0.02–3.7 GPa)

so the metal takes all the load, and the real bone around it actually weakens because physics says "why maintain structure that isn't carrying stress?" (stress shielding)

enter selective laser melted Zn-1Mg-0.1Sr gyroid scaffolds:

→ mathematically generated TPMS gyroid lattice (70% porous, 550 μm pores)

→ elastic modulus tuned right down to 2.3 GPa so it flexes like real cancellous bone

→ alloying zinc with 1% Mg + 0.1% Sr precipitates Mg2Zn11 & SrZn13 intermetallics, more than doubling strength over pure zinc (33.7 MPa)

→ degrades at 0.36 mm/year with zero hydrogen gas pockets

and the wildest part
as it dissolves, it turns its own surface into calcium-phosphate & zinc-phosphate minerals while feeding Zn2+ and Sr2+ ions that make bone-forming cells grow faster

titanium tricks the skeleton into adopting permanent metal
this thing holds the load, feeds the bone to rebuild itself, and vanishes when the job is done.

radical engineering.

@Saint_n0mad what the fuck man.

@poteto Are you limited by compute or is ~5000 PRs the current SOTA limit?

we absolutely should in fact genetically engineer bioluminescent plants & trees and then completely eradicate the affront to God that is LED street lights from the face of the Earth

The only way out is through.

They're calling it the Bugpocalypse. LLMs are being used to find long-hidden cracks in the software infrastructure, and it's happening at a furious rate. 3% of all compromises in computing history happened in the last week, claims one source? I believe it.

There are people saying public access to the frontier models ought to be locked out, or heavily guardrailed, over this. The problem with that idea can be summed up in one sentence: when lockpicks are outlawed, only outlaws will have lockpicks.

The lockpicks will be Chinese open-weight models, if nothing else. There's no way to stop those from becoming ubiquitous.

There are two futures in front of us. One in which only the bad guys have lockpicks, and security holes go undiscovered until they're exploited. Another in which everybody has lockpicks and is aggressively red-teaming their own software so it gets fixed before the holes are exploited.

The corpus of human code is huge but finite. The number of defects in it has to be finite too. We can fix those defects now; we have a million friendly robots to do it with.

The only way out is through.

What’s actually going on in Ukraine is that there is a massive incentive difference between the elites and the people.

The former have grown very rich off the hundreds of billions flowing to Ukraine, while the latter’s children are conscripted to die in trenches.

@Rothmus Those who are opposed to corporations and favor government do not realize that government is simply the largest, most monopolistic corporation of all and it has a monopoly on violence.

@keennay That's a crazy image

@dok2001 I think she just needs to hire cracked engineers.

Good piece on how OpenAI thinks about its FDE efforts and how the role now involves making yourself obsolete every few months

Oh my goodness this has to be right.

Instead of generating a random 256-bit number they generated a random number between 0 and 256.

That’s how they got 4, 66, 155, 156, 230 and 237.
