Traits, Enums, and Typestate allow much richer paradigms at much lower cost

is it working though? The main outcome we've seen with companies that drink the AI Kool aid en masse is buggy unstable systems. clearly there's a level of rigor that's being missed for ship velocity

When you write Rust long enough you settle on certain architectures (message passing, event loops) that go well with the borrow checker, and don't end up thinking about it too much. Plus you can always throw an agent at the first set of errors from the refactor and let the compiler guide the annoying parts.

It seems like the problem in this application is that attention itself. Makes me wonder if using a transformer for transcription is the correct architecture.

While not an RF book per se, High Speed Digital design does a great job of spanning the gap from EE undergrad to the basics of RF as it relates to digital design. I'd also recommend brushing up on more advanced E&M, eg T{E,M} modes and antenna design if you haven't looked at them in a while

No mention of how he was essentially homeless and collabed his way thru thousands of papers? Or the whole "You have set mathematics back a month" episode?

Absolute legend!

JWT operates on a different principle; the user's private key (API key) never leaves the user's device. Instead, the stated "role" and other JSON data are signed with the servers pubkey, then verified by the server using its master key, granting the permissions that role allows.

1 exabyte/month is 380GB/s, which would be pretty epic in my opinion!

Even the most complex distributed systems can be understood with the context windows we have. Short of 1M+ loc, and even then you could use documentation to get a more succinct view of the whole thing.

I wonder how well local inference would work on these.

I think it's safe to assume given recent storms that the 1% floodplains are _underestimating_ the risk

The price of the carried inventory is still significant; the scale they mention reaching towards is thousands per day. That's not including the backlog of components they would have onsite to ensure production uptime.

My point is that we really don't know what "plausible" is anymore with these storms. That much is clear in the data. It seems silly to be so close to a flood zone with your very expensive DUV/EUV machines. There are probably other places they could have placed this facility.

Helene survivor here. What's wild to me is that, regardless of the small scale of this facility, it's only a few hundred meters from a 1% flood zone: https://msc.fema.gov/portal/search

The address I found for the facility is 9101 Windmill Park Lane Hudson, TX 77064

This seems ill advised given recent events like Hurricane Harvey

Indeed, the connection to Stokes here is via the fact that both operators (abstracted derivative and antiderivative) are linear operators.

Huh, never thought about the potential connection between the set-containment operation and Stokes like that.

How would this product compare to a PostgREST based approach (this is the cool tech behind the original supabase) with load balancing at the HTTP level?
