Average life expectancy is the wrong thing to use here, since life expectancy _assuming you're still alive at 74_ is actually 13.1 yr in the US.

Say hypothetically that they were concerned that GPT models would see widespread abuse, for example by students cheating on homework assignments, in a way that could cause likely-irreversible societal changes some of which are harmful. Can

Sorta, but it's important for the calling convention that the compiler is consistent on what is done at compiletime vs runtime. Because methods are "normal functions" for the calling convention (and can be assigned to functio

I wonder if npm could run a program where package uploads are automatically delayed for ~10min while they get distributed to an ecosystem of third-party code auditing companies for automatic checks. You could have a public leaderboard of wh

This is exactly what the Starlark language was developed to solve, initially for Bazel but also used other places. It's a "full scripting language" but intentionally doesn't (in default configuration) support recursion o

In the context of this thread, it's worth pointing out that "trying to deceive regulators" is quite normal behavior for individual human drivers involved in car incidents, and iirc the Cruise collision itself also involved

They successfully built local privilege escalation exploits (from several bugs each), and found other remotely-accessible bugs, but were not able chain their remote bugs to make remotely-accessible exploits.

Not even mentioned in the article, my favorite capability is the new `//go:fix inline` directive, which can be applied to a one-line function to make go fix inline it's contents into the caller. That ends up being a really po

Do we even know that the child was injured? All I've seen anyone officially claim is that the Waymo made contact, the kid fell over, then stood up and walked to the side of the road. Assuming the Waymo was still braking hard, 6mph mean

Your expectation is wrong in this case for almost all languages. The design of Pylance (as is sorta forced by Python itself) chooses to execute Python to discover things like the Python version, and the Python startup process can run arbitr

I did a pretty deep dive into this recently, although haven't yet started any implementation work. As far as I can tell, the best strategy that preserves Linux's open-source and user-empowering ideals as much as possible: - The ga

Doing some quick math, if your bike is using 3kw to climb a reasonably steep (15% grade) hill at 8mph, we can calculate the weight it must be carrying, which ends up being about 1,200lbs To answer your question, the limit on motor power exi

A friend of mine created something similar using a numerical optimization based approach to minimize distortion. He also made the artistic choice to split the water between Australia and Asia to get even lower distortion. See Elastic II her

There's a lengthy, and quite good, deep-dive into Alpha School by a current parent here, for anyone interested. Spoiler, "AI" isn't that big a portion of what they're doing, but some of their insights and systems ar

Feeding random inputs to a crypto function is not guaranteed to exercise all the weird paths that an attacker providing intentionally malicious input could access. For example, a loop comparing against secret data in 32 bit chunks will take

The original groupcache is basically unmaintained, but there's at least two forks that have carried on active development and support additional nice features (like eviction), and should probably be preferred for most projects. https:

I highly recommend revup, it allows managing and uploading stacked (or arbitrary trees of) PRs to Github, including adding a comment that shows approximate revision-to-revision diffs if you want it to. I don't actually think that per-c

I believe it's a 360deg planar lidar mounted on a vertical plane, with a motor to rotate it around and slowly cover a full 4pi sphere. There's also a fisheye camera integrated in. This is a pretty common setup for scanning station

Do you have other sensors in the same price range that you'd recommend instead for most uses? How much accuracy improvement would you expect?

It seems like a 24hr delay for auto upgrades would mitigate a lot of this, maybe with some way that a trusted third-party could skip the delay for big-ticket zero day patches?

It looks like the TID is stored directly in the pthread struct pointed to by %fs itself, at a fixed offset which you can somewhat-hackily compile into your code. [0] In the process of investigating this, I also realized that there's a

Presumably you could store the TID in every event, or otherwise check whether the TID has changed since the last time it was logged and push a (timestamp, TID) pair if so. Reading TID should be cheap.

In addition to the other good answers, if the amount of state that's explicitly managed by software gets too large then it gets really expensive to save or restore that state. This happens, for example, when a syscall transfers control

It sounds like one function in libmodem accepts a pointer to a configuration struct, then stores that pointer (or an interior pointer from within it), which is then later used by another libmodem function later. If all of libmodem were wr
