Wages, after adjusting for inflation, are more than 20x greater today than they were 200 years ago. That's why infant mortality has declined so much.

We still have a lot of room for improvement, with the masses still forced to subsist on sub-par products (e.g. ultra-processed foods, products that poison them with microplastics, etc) and long work hours just to afford basics (housing, healthcare, childcare, etc), and the only way to get there is continued economic development, which literally amounts to automation of labor-intensive production processes.

Wages strongly track per capita GDP. The natural instinct to be cynical is misguided when it comes to expectations regarding the impact of automation.

Sustained cycling is intense exercise. Your body burns through its glucose reserves rapidly, and if you run out of energy the effect ("bonking") is awful. On the other hand, trying to eat a bunch of energy and having too much in your stomach will make you sick and is also awful. So you do in fact want to ingest the most you can process (but no more) per hour, particularly for extended events.

Nutrition doesn't matter for rides up to 15 miles, and you can improvise almost anything for rides up to 40 miles. More (or particularly hilly courses, etc.) and it becomes very important to get the amount you eat and drink right.
Well, they allowed kings to run the nation, that's scary.

But Chevron is about a different project. It's ambition is to fulfill the Federalist Society fantasy of de-governance.

What comes from that isn't direct authoritarianism by government. It's unchecked corporate greed control & influence, with a government maimed and without ability to respond or act. Making rulemaking & regulation impossible, preventing defense of consumers, is the plan for Federalist Society's unchecked economic totalitarianism.

Maybe perhaps possibly we see a legislature better able to wield and use power, after this redefinition of government. But with the shape of the Senate favoring small states >> 10x big states, it seems unlikely that the will to govern will finally get upper hand over the will to de-govern.
I have a very similar experience. A worthy distinction is that in my dreams I'm either a) fully aware it's a dream but have no control or b) fully in control of myself without realising it's a dream.

> Are they talking about a reactionless drive?

No.

The “warp shell allows one to modify the state of spacetime inside it…the time in the inner region may go faster or slower than it would go without the shell” [1]. Being “internally moving shells of normal or exotic matter,” these warp shells “do not have any natural way of changing their velocities. They are just like any other types of inertially moving objects. Similarly, just like for any other massive object, achieving a certain velocity for a warp drive requires an externally applied force or, more practically, some form of propulsion.”

Subliminal warp drives let a timelike passenger compress the subjective experience of the journey. It doesn’t change the journey’s propulsion requirements. Think: cryosleep benefits from science fiction, not Star Trek-esque warp.

> If you can't share memory between threads you can't write high performance programs.

I don't know whether shared memory is required for high-performance programs but I do know that python THREADS can share memory.

The GIL means that only one thread is executing bytecodes at a time. That's it. It doesn't place any other restriction on python programs.

I write crypto trading code in python. It takes 0.1ms from the time I receive a packet until the time I send the packet containing the trade based on receiving that packet. Yes, that 0.1ms includes the logic to decide whether to trade.

FWIW, that chain of processing happens to involve two threads that share memory.

Seems to me this is the equivalent of fast retrieval and piecing together from a huge amount of examples in the data. This might take far more time if you were to do this yourself. That's a plus for the tools. In other words, a massively expensive (for the service provider) auto-complete.

But try to do something much more simple but has much fewer examples (a typical case is something which has bad documentation) in the data, and it falls apart. I even tried to use Perplexity to create a dead simple CLI command, and it hallucinated an answer (looking at the docs, it misused the parameter, and may have picked up on someone who gave an incorrect answer in the data.)

>"Topological Quantum Chemistry (TQC) links the chemical and symmetry structure of a given material with its topological properties.

This field tabulates the data of the 10398 real-space atomic limits of materials, and solves the compatibility relations of electronic bands in momentum space. A material that is not an atomic limit or whose bands do not satisfy the compatibility relations, is a topological insulator/semimetal. We use TQC to find the topological stoichiometric non-magnetic, "high-quality'' materials in the world. We develop several code additions to VASP which can compute all characters of all symmetries at all high-symmetry points in the Brillouin Zone (BZ). Using TQC we then develop codes to check which materials in ICSD are topological. Out of 26938 stoichiometric materials in our filtered ICSD database, we find 2861 topological insulators (TI) and 2936 topological semimetals (2505 and 2560 non-f electron, respectively). Our method is uniquely capable to show that none of the TI's found exhibit fragile topology. We partition the topological materials in different physical classes. For the majority of the 5797 "high-quality'' topological material, we compute: the topological class (equivalence classes of TQC elementary band representations -- equivalent to the topological index), the symmetry(ies) that protects the topological class, the representations at high symmetry points and the direct gap (for insulators), and the topological index. For topological semimetals we then compute whether the system becomes a topological insulator (whose index/class we compute) upon breaking symmetries -- useful for experiments. 2152 more TI's are obtained in this way. For almost all 5065 non-f-electron topological materials, we provide the electronic band structures, allowing the identification of quantitative properties (gaps, velocities).

Remarkably, our exhaustive results show that a large proportion ( ~ 24% !) of all materials in nature are topological..."

Absolutely fascinating!

Is two comments really a "pile on"?
I did some quick research and found that there is an "async job" API in OpenSSL. That one appears to do IO though, it even says that creating a job is a very expensive operation and thus jobs should be reused.

Is the similarity you are seeing that the work itself that gets scheduled via a job is agnostic over how it is executed?

From this example [0] it looks more like that async API is very similar to Rust's futures:

- Within a job you can access a "wait context"

- You can suspend on some condition

- You can trigger a wake-up to continue executing

> Would a sub light warp drive be much different performance wise from, say, a fusion torch engine with insane iSP

Yes.

The “warp shell allows one to modify the state of spacetime inside it…the time in the inner region may go faster or slower than it would go without the shell” [1]. It is not a system of propulsion.

That said, the paper does hint at forming “a region within a subliminal warp drive which is similar to ergospheres of spinning black holes” for use “as an efficient energy storage” and “wherein black hole-like regions of the spacetime may be used to produce accretion power” for “both a source of energy and a source of propulsion.”

> Would you experience time dilation?

Theoretically, not sure. Practically, yes: you would appear to an outside observer to be travelling subliminally.

> When you kicked off the drive what would your momentum be relative to your destination?

Whatever it was immediately before.

> Would speeds like 99.99999% the speed of light be possible with enough energy?

Yes. Same as it already is.

> We use a host of quantitative and qualitative measures. None of them show any positive improvements. These include the basics like roadmap reviews, demo sessions, feature cycle time, etc as well as fairly comprehensive business metrics.

Those are very high level. If there's no movement on those, I'd guess there are other things bottlenecking the teams. They can code as fast as possible and things still move at the same pace overall. Nice thing to know.

If you want to really test the hypothesis that Copilot and ChatGPT have no impact on coding speed, look at more granular metrics to do with just coding. The average time from the moment a developer picks up a work item to the time it gets merged (assuming code reviews happen in a timely fashion). Hopefully you have historical pre-AI data on that metric to compare to.

Edit: and average number of defects discovered from that work after merge

> Mobile phones had tiny utility compared to smartphones

They had tiny utility compared to modern smartphones but the first iPhone was a glorified iPod with a touchscreen and a cellular radio. It didn’t have an app store and the only thing it really did better than other mobile phones was web browsing, thanks to the touchscreen keyboard.

It wasn’t as revolutionary as hindsight now makes it seem. It was just an iteration on PalmPilots and Blackberries.

I’m still using Vision Pro for about 10-15 hours each week, but the bulk of that is spent mirroring my Mac or having focused writing time using the Obsidian iPad app—there really aren’t apps that take full advantage of the platform yet (and I don’t watch a lot of movies). Still, it’s been the best way to stay productive away from my desk. The launch was a bit rocky with bugs and missing features, but the recent updates to mirroring and keyboard/mouse support are starting to hint that Apple is focusing in on productivity as a first-class use case. I’m okay paying the premium knowing that this platform has the potential to keep heading in this direction. It feels like the hardware has a decent amount of headroom.

> Doctors can be associating what they’ve learned, often with heavy biases from hypochondriacs

So true. And it's hard to question a doctor's advice, because of their aura of authority, whereas it's easy to do further validation of an LLMs diagnosis.

I had to change doctor recently when moving towns. It was only when chancing on a good doctor that I realised how bad my old doctor was - a nice guy but cruising to retirement. And my experience with cardiologists has been the same.

Happy to get medical advice from an LLM though I'd certainly want prescriptions and action plans vetted by a human.

In Firezone's case, things are built on top of UDP so technically there aren't any (kernel-managed) connections and only a single file descriptor is allocated for the UDP socket.

The main benefit is being able to use `&mut` everywhere: At the time when we read an IP packet from the TUN device, we don't yet know, which gateway (exit node), it needs to go to. We first have to look at the user's policies and then encrypt and send it via a WireGuard tunnel.

Similarly, we need to concurrently receive on all of these tunnels. The tunnels are just a user-space concept though. All we do is receive on the UDP socket and index into the corresponding data structure based on the sending socket.

If all of these "connections" would use their own task and UDP socket, we'd would have to use channels (and thus copying) to dispatch them. Additionally, the policy state would have to be in an `Arc<Mutex>` because it is shared among all connections.

My “NAS” is my late model Intel iMac. I have, like, 5 USB drives hanging off it.

I SyncThing my wife’s laptop to it. I serve a bunch of videos off of it to our AppleTV. All our photos are there.

I have a Time Machine backup of the main system drive (my wife uses TM as well). The whole thing is backed up to BackBlaze, which works great, but I have not had to recover anything yet.

I would like to run ZFS mostly to detect bit rot, but each time I’ve tried it, it pretty much immediately crushed my machine to the point of unresponsiveness, so I’ve given up on that. That was doing trivial stuff, have ZFS manage a single volume. Just terrible.

So now it’s just an ad hoc collection of mismatched USB drives with cables not well organized. My next TODO is to replace the two spinning drives with SSD. Not so much for raw performance, but simply that when those drives spin up, it hangs up the computer. So I’d like SSD for “instant” startup.

Not enough to just jettison the drives, but if opportunity knocks, I’ll swap them out.
