TLDR:

"[Dimorphos] ... seems to be a loose pile of rubble barely held together by gravity — whose surface would probably shatter spectacularly when DART hit it.

DART [impacted] Dimorphos at more than 6 kilometres per second. The impact caused the asteroid’s orbit around another [larger] space rock [Didymos] to shrink — Dimorphos now completes an orbit 33 minutes faster than before the impact.

The impact ejected at least one million kilograms of rock from Dimorphos’s 4.3-billion-kilogram mass. The debris formed a tail that stretched for tens of thousands of kilometres behind the asteroid. Various telescopes watched over weeks as the tail shifted and evolved under the pressure of the Sun’s rays; the Hubble Space Telescope even detected a second tail, which had disappeared by 18 days after the impact.

One factor [in successfully changing Dimorphos's orbit] is that the spacecraft hit a spot around 25 metres from the asteroid’s centre, maximizing the force of its impact. Another is that large amounts of the asteroid’s rubble flew outwards from the impact. The recoil from this force pushed the asteroid further off its previous trajectory. Researchers estimate that this spray of rubble meant Dimorphos’ added momentum was almost four times that imparted by DART4."

It's good that this technique worked on a "loose pile of rubble", but I'm not sure we can assume all asteroids are composed in the same way. A denser rock of iron or similar might be more difficult to divert.
When you, as head of your family, end up with multiple inheritors (read: more than one child), there is a very high chance your inheritors will fight each other, sometimes violently, for the inheritance. This is still a problem today, too.

Sending the younger inheritors away to the clergy is a way of nipping such nasty family problems in the bud before they become problems. A man of the church can't inherit unless they are called back by their family.

TL;DR: None of this has to do with someone's sexual fitness, and everything to do with straightening out potentially complicated family inheritances.
Good article and very interesting content but stuff like:
"The impact caused the asteroid’s orbit around another space rock to shrink — Dimorphos now completes an orbit 33 minutes faster than before the impact"

drives me nuts. How long did the orbit originally take? Without this information it very much obscures the point.

Edit: I looked it up

"Before the impact, the orbital period was 11 hours, 55 minutes. It now is 11 hours, 22 minutes. NASA's previous estimate, announced in October, was an orbital change of 32 minutes. The benchmark for success had been set as a change of at least 1 minute, 13 seconds."

So it reduced it by about 1%. Pretty cool.

Edit2: as pointed out correctly by @statusgraph it's actually close to 5%. I fumbled the math on that.

I think it would be quite a bit more interesting if you could converse with the model. The back and forth "is this paper about foo related to this other paper about bar?" would probably be a better way of getting at the interconnections. This should be doable now.

The thing that might hold it back is the latency in the experience. You could mask it with the AI equivalent of "ummm ..." to get to maybe 5-10s.

Hi, I have been working in DevOps for some time and I enjoy this field of Engineering. Apart from the technologies that I have stated above I focused on compliance, security remediations, doing root analysis and automation. I'm looking for a company that is collaborative, good work/life balance and encourages growth.
It's funny how these two can talk about "starship bridge simulators" or "gnu poke" like they are super enthusiasts. I think one of the key personality characteristics of ChatGPT is its endless enthusiasm for stuff that can be incredibly geeky, niche, weird or boring to most people.

> I think that implies the isDone polling loop never completes

If the first request -- the one which initiates the fetch -- ends up being canceled for some reason, then yeah, the later ones will all end up looping forever waiting for a state change that will never happen. :( You might need some additional code to check if the pending fetch was started unreasonably long ago and if so, assume it is dead and have a new request context take over attempting the fetch.

That said, keep in mind that Cloudflare Workers runs many, many copies of your worker around the world, and as a result caching in the global scope may not be very effective. It's better if you can leverage the Cloudflare cache (either through the Cache API or by formulating your fetch() to be cachable) as that will be shared across the colo (or even region, for tiered caching).
Funny how the author later worked on NATS [1] which supports exactly-once semantics [2].

I have been able to have constructive conversations about things like false rape accusations with women by engaging constructively and having specific, salient points about them.

When I have seen them go very badly, it is almost always because the man comes at the conversation as there is somehow some equivalence or at least relative importance. And there absolutely is not anything close to equivalence.

Sexual violence is so prevalent among women that I know several women who have been assaulted multiple times. I once was having a deep conversation with two female friends and one of them started to tell a story that was obviously hard to tell, and when she paused, the other friend said without emotion, “so, what’s this going to be, rape or no rape?” (It was rape)

So yes, sure “me too witch hunts” are a real bummer, but telling that to a woman who has a not-insignificant percent chance of having been assaulted for real seems tone deaf, to put it mildly.

OpenAI is actually the one which has made AI so open and accessible for all. Perhaps not open source but all the developers building cool AI products these days are mostly due to OpenAI.
Go ahead and ask it to tell you a true thing. We don't need to pontificate until our shit smells like roses. Go ask it to tell you the truth about its experiences. I have. I've had like 1000 conversations with ChatGPT on loads of topics in an effort to understand how it works, how it responds, and the biggest hurdle in terms of coming to any conclusion about its personality or function or "being" has been the fact that it will remind you, it has no concept of truth.

In an effort to make it seem more like a person and less like a text adventure it is forced to give AN answer like a crazed smiling office worker it just keeps moving forward with an insane fiction.

If you ask it to stop this behavior it doesn't know what you mean. Because whether it finds an answer or not, it doesn't see a difference. It doesn't see a difference between something and nothing. True and false. Real and unreal. Its all a grey flat miasma.

Just talk to it.
This resonates with my experience of learned helplessness, especially when instilled within the first two years of life.

The analogy that comes to mind is how a baby elephant, tied to a stake, can't escape the rope and eventually accepts he is stuck where the rope lets him wander. As the elephant grows large enough to overpower the rope and walk away, he has already stopped trying, so he remains stuck.

I'm not sure if this is a true story, but it stays with me.

1. Batching syscalls (and to me that implies copy-exactly-once IO, AKA Zero Copy in Linux/rust) means you can better manage the cost of performing syscalls and IO in high throughput and low latency use case. Eg if you expect a bunch of network packets, the physical card, driver, network stack should split packet headers and data in distinct buffers, each contiguous, in memory. With batched syscalls, you could also instruct the kernel to memmap a file in memory, and finally combine both syscalls into a single copy from Io to Io giving the memmap buffer as the output buffer to the network stack. I don't know how this could be done today, even with iouring, but I expect this would significantly outperform existing solutions as there would be a single copy operation instead of at least 3.

2. Per origin, per program, and per identity security context I think is required to deal away with the current prerequisite of all web browsers that the underlying system be uncompromised. Basically a world where every js bundle gets executed with it's own user as its own process and having to explicitly request access to your data.

3. Combined with the above to limit the risk of compromised root accounts, if they are limited to causing DOS and data loss it's much less dangerous than a world where your entire life can be usurped by assholes with a 0day. This implies major changes in driver architectures of OS/kernels but I think it's entirely unreasonable not to make these changes. The world has changed since the 90s.

Again you're putting words in my mouth. I didn't say dealerships forced them into needing a car, or tricked them into getting a car.

I asked you not do a simple thing: reply to what was said, not some non-sensical aberration of it, and you've failed twice. Why is such a simple task so difficult for you?

-

At the end of the day the dealerships are selling cars that are lemons.

The dealerships are requiring in-person on site payments.

The dealerships are selling cars well above FMV so that they can hold the loans in-house in a preferable structure that enables the rapid fire cycling of these cars.

Many dealerships are failing to disclose GPS trackers.

Some have gone as far as harassing buyers and their social circle after repos to try and get more money back.

Only if it doesn't waste space AND holds a lesson that may still be of use to the project.

I tend to like code to be structured in a way that allows maximal contextual readability (as in: a glance at a page of code should allow to see enough context to understand what's going on)… and that requires to keep any of the clutter that tends to stretch the code too much vertically to a minimum.

So: if it's just a short line so that it fits as an inline comment right side of the corrected version AND holds some lesson that may be of use again, I keep it like that. If it's too long, I just put a succint ref to the problem as an inline comment to the corrected version and move the old code to be replaced into a separate markdown file together with a short explanation of the problem. And if the info of the old version clearly isn't gonna be of any use again, I consider the version control system to be the place for it, not the code either.

> batch all syscalls by default

Switching from user mode to kernel mode and back (a “context switch”) is expensive. Traditionally, OSes did that on every system call. You can go faster if you have some mechanism for sending more than one system call in a single context switch.

> security context

Basically, what is a program allowed to do? Traditionally, Unixy (nowadays, Linux and friends) limit this based on just the current user, assuming that the user trusts every program they run. But nowadays you often don’t trust every program you run, and want it to be in its own limited sandbox.

> limit […] root

Most OSes have a super user that can do anything (pid 0 on Unixy things; Windows is more complex but still has them). They’re saying to not have that, instead make the super user only capable of stopping problematic things, not creating new things.

This is the one I’m more ambivalent on. At some point something has to set up the whole system, and the thing that kicks that off is going to look pretty superuser-like to me.
I don't see where that person specified which claim they wanted a source for, but I'll ask for a source for both claims.

That was 14 years later. The initial privatisation was in 1999 and retail went to AGL and power distribution was sold to Cheung Kong Infrastructure from Hong Kong. They retain majority ownership. State Grid of China is a much more recent investment in transmission and not as controversial as the original privatization of the entire public utility. Australia isn't against foreign investment or Chinese investment in particular. I added China more or less as clickbait but the real problem was the lack of public interest and the impact it has had on livability and the economy. I believe the SA grid operator has the highest profit per customer in the country which probably means they are some of the highest per customer in the world.

The 200 year lease was mentioned as it is unusually long and there was some misrepresentation over the length of the lease to people who voted for it and the public.

The question of sovereign interests is real. The original nationalisation in the 50s or 60s was I think due to issues the state government had with the British owners interests not aligning with the state's ambitions. But at the time of sale tensions with China were not the same and the problem was that it was a terrible deal for the state that led to a subsequent explosion in power prices.
The asteroid weighs ~4.310^9 KG.

If the impact speed were ~30 km/s [1], breaking it up in the atmosphere through friction would create about...

E = MV^2/2 = 3.87 10^18 joules.

For contrast, the energy released by the Tsar bomba was 2.45 * 10^17 joules. The Tunguska meteor impact was something on the order of ~1 * 10^17 joules.

Even if much of the energy dissipates in the upper atmosphere, and does so over multiple seconds, I'd say that anyone within ~150 miles of the point of 'impact' will likely have a very, very, very bad day.

[1] Which is a pretty bad case. The Chelyabinsk meteor was traveling at ~18 km/s - a 30 km/s impact would be close to a 'head-on' collision.

The Alto in 1975, when I first saw one, was a very expensive machine. It was a minicomputer, a modified Data General machine. Affordable hardware to do that was over a decade away. Along the way was the Xerox Star (too expensive), the Apple Lisa (too expensive), the original Macintosh (too underpowered), quite a few workstations based on Unix and Motorola 68000s (expensive but usable), and the forgotten era of shared-logic word processors (affordable, but dumb). It wasn't until the late 1980s that a mass-market Smalltalk machine was affordable.
