> I don't understand your objection to the slicing procedure.

It's simple: any "slicing" is frame dependent. And relativity says that things that are frame dependent do not have any physical meaning.

> The central assumption is that for a reasonably physical spacetime there exists a unique maximal globally hyperbolic solution to the field equations

Yes, but globally hyperbolic spacetimes still do not have unique slicings. There are still an infinite number of possible slicings, corresponding to the infinite number of possible inertial frames in standard SR.

> In which of your three regions do we find the freedom to do this?

If the universe is fully deterministic, then in one sense of course there is no "freedom" to change anything. But we don't know that the universe is fully deterministic (and QM strongly suggests that it isn't). But whether it is or not, the distinction I described is still there and still valid, since that distinction is about what we know at a particular event in spacetime.

> In a Big Bang universe all points are in the future light cone at BB

No, they aren't. The Big Bang is not a single point. It's a spacelike line. There are an infinite number of causally disconnected points one "instant" after the Big Bang.

Similar remarks apply in time reversed form to the Big Crunch in spacetimes that have it.
I doesn't make up SMAGs' reputation: all I know is what retired "nukes" report. Ask them.
As I wrote elsewhere in this thread (though I was downvoted), I suspect the reason is that this benchmark is measuring the total execution time of a single run of an executable. This would include any time spent by the executable to bootstrap its runtime environment, initiate a virtual machine, and whatever else it needs to do in addition to the relevant code at hand to process the string.

Such a test will favor implementations that have extremely svelte boostrapping, allowing them to immediately begin executing the relevant code and return a result.

I feel a more useful test would be for the relevant string processing code to be run tens to thousands of times within the process itself, so as to diminish the relative importance of boostrap/warmup code and/or runtime optimization performed by VMs. Unless, of course, part of the intent was specifically to measure the impact of the bootstrapping.
Dealing with Heat Exhaustion
For me it was an incredibly laughable shift of blame to renewables. People tried saying wind power wouldn't work in the cold, when Iowa, MN, and the Dakota's make huge amounts of it year round. I'm not a scientist, but pretty sure they get much, much colder

I'm no expert but I took my kid to a speed-cubing event and we watched. The referees secretly set up the hidden cubes to be used for competition to specific randomized configurations which are determined automatically by a software program for each cube. I assume this program ensures that no competition cubes are scrambled such that they are excessively easy to solve.
I'm not claiming there are no overly stubborn PIs. But we should not be lazy and paint so a brush that we view the field as a monolith.

Cluster API allows you to create clusters with helm charts.

We use ClusterAPI + a centralized ArgoCD to push our clusters that’s other teams can use but with all the required add-ons that the business says we need like security tooling and policy management.
Also, any interstate project is subject to a he-said she-said of who should pay for it.

As with many conditions, the root cause is posture. the neck and spine have a natural posture we're meant to use most of the time.

Competitive road cyclists' posture is completely forwards, for aerodynamics, better climbing, etc. Using it may be a useful tool in your 20s / in competition but otherwise it is wise to use an upright position, which will take the least toll and will be fastest to recover from.

Some bike setup tweaks can make a (more) upright position easier - from higher handlebars, to moving the seat forwards, to even getting a slightly shorter bike frame (since in the case of mountain bikes, they tend to be longer for greater stability).

Finally, while riding you should be looking up, at the horizon practically, not at the cockpit.
This is an unpopular opinion but speaking from experience, it’s absolutely true.
I wonder what would have happened if she had shared her salary on LinkedIn.

I'd imagine defending the argument "because you have a LinkedIn account" would be pretty tough as upwards of 90% of employees including senior management works likely have one. And it's often crucial in the process of getting a job. Probably this company also has a box where you can apply and import your LinkedIn details when applying. That would make such a dismissal indefensible.
> is that a very appreciable fraction of the energy liberated goes into radiant heat and light

That's exactly what I said in my previous comment:

For example nuclear bombs melting flesh is because of the extreme heat, nothing that is unique to the nuclear process.

You see exactly the same "flash burn" characteristics from other very hot weapons eg thermobaric explosives.

The unique thing about nuclear bombs is their scale and the fallout afterwards (both of which are horrific). That "melting flesh" thing is caused by the extreme heat, not by some magic "it's nuclear" thing.
Using tools, formats or workflows that you will lose access to in the future is the problem here. I have work going back decades and not much that I can think of that I couldn't resurrect in some form with relatively little effort.

Having screenshots of thing that are otherwise lost would just make me sad. It's like preserving a single frame from a movie and losing the rest.
As someone who lives practically next door to the new Taylor fab(s) I am not sure how to feel about this.

When I moved here 20 years ago the population was 5,000. It has now grown to 30,000+ and the infrastructure has not kept up at all.
This, "we don't have to be right, just loud". Personally I feel like this is the environment that spawned the tea party.

> … denied that its equipment is capable of operating in any communications spectrum allocated to the Defense Department.

That would tend to indicate “broadcasting” in that spectrum.

> … multiple sources familiar with the investigation tell CNN that there's no question the Huawei equipment has the ability to intercept not only commercial cell traffic but also the highly restricted airwaves used by the military …

Anything with an antenna could do this.

> … and disrupt critical US Strategic Command communications …

Now it’s looking more interesting. But in what way could this disruption happen? Is there actually broadcast equipment in the devices? Some kind of jamming gadget?

I’m no fan of outsourcing critical infrastructure to other regimes with whom we are likely to disagree. I would, however, like to understand the particular threat rather than have these vague indications that maybe possibly something could happen.
One old and tested solution is that you play with your friends or people you trust. This has worked perfectly for board games and other pre-internet games for many years.

Otherwise if you want to play at a bigger scale, I don't know how you would do that. Maybe that's just the lesson you have to learn, that random people on the internet can't be trusted.

Penrose's The Emperor's New Mind contains a good layman's discussion of it. (It also contains a good example of a layman's work that makes the same mistake the article under discussion here does: even after going to all the trouble to explain in detail how the three regions I described work, and how "now" slicings, unlike the three regions I described, are frame-dependent and don't have physical meaning, he then makes an invalid argument for the "block universe" viewpoint that depends on ignoring the three regions and treating "now" slicings as though they do have physical meaning. It's an excellent example of how even experts of the stature of Penrose can get things wrong.)

The 13 MBP with M2 is almost the same price as the M2 MBA. The MBP is a little more performance when running continuous heavy processing due to its fan. The MBP is also thicker, heavier and has a fan running. The MBA runs almost as fast but is lighter and never has a fan.

If you look at the Six Colors review, they show some throttling at 10 minutes on a Cinebench test. The MBP with a fan scored 8638 and the MBA without scored 8211. That kind of difference is not worth adding a fan or putting in some heat pads that make the case get hotter. It just means that the most portable Mac is ever so slightly slower than the low end Pro Mac. I'm happy with that.

Speaking as a Texas resident who used to work in fabs, you may have a point, but only if they actually do 11 fabs. I think a more realistic interpretation is that there are 11 sites they are considering for fabs (and want to get the government paperwork ball rolling on), of which only a few will be used. Texas does have a tight labor market, but since a lot of the technical hiring would not start for a year or two, I expect that hiring for these fabs (assuming we're talking 2-4, not 11, actually get built) would be challenging, but not too challenging.
True but you could make that kind of argument about a lot of things. Like literally anything that could negatively affect one's physical health. So alcohol, sugar, lack of excercise, a non-vegan diet, etc etc.

My point being that if you're going to make that argument, then effectively what you really need to do is make an argument for where specifically to draw that line, and that's a much harder argument to make.
Would love to see an "awesome" list for all business UI frameworks like this.
Sometimes true, but not, I think, in fab construction, not even in Texas.
Public transport in the US is an absolute impossibility outside of dense urban environments. There is way too much sprawl to ever have a reliable public transport network in the US. Best we could hope for would be high speed rail to connect urban areas and replace short/medium distance air travel.

just one of those.

They might be mostly confined to Apple fans; I don't know. They do seem, in general, to want a universe of fanboys. Fortunately, Apple TV isn't very sticky that way, so far at least. I watch it completely on non-Apple equipment.

Do you think running k8s at home is worthwhile, past the learning experience and cool factor?

I have a nice server that I used for 10-20 applications like Time Machine backup, media streaming, file syncing, home automation, etc. I was looking into k8s, but it seemed way too complicated when I only have one physical server, so I went with Docker + Docker Compose instead.
Yeah, the question is: why this, and not just put in with Project Gutenberg?
Clearly your first statement is incorrect: Android is an example of a Linux system that doesn't expose a GNU userland. As for “the majority”. I don't know what you mean by that. The vast majority of computer users don't have any experience of anything that is released by the Free Software Foundation; they just use applications, some of which are released under the GPL (e.g., Audacity or VLC), and most of which are not. So what is the population of which the majority is unable to use GNU products?

Re Emacs: there is a substantial community of Emacs users. These people have not found it unusable. That other people use vim, VScode, or something else, or have no use for a text editor, doesn't undercut this fact.
> 40 megawatts. If you need to get cracking, the high-power state would draw as much as a constant 120 MW.

In a one meter diameter tunnel, or in this case, a long and really hot oven. 120MW are enough to turn a metric ton of most rock into magma every ten seconds.

In any case I guess Earthgrid will join the small club of companies and government programs who require extremely high temperature electronics. I'd also bet that these things will have limited sensors and give little feedback about what's actually happening in that tunnel. That or they'll need some fancy cooling idea or a pause until the tunnel cools down. Maybe the hot rock that is removed could be used to carry the heat away?

And that's just worrying about what the heat will do to your device. You'll also have to think about what it will do to the material you're tunneling through. Will the rock around you lose stability at higher temperature? Will water within the rock expand violently and collapse your tunnel? Will your device get stuck when everything around it turns into sticky goo? Will you set fire to whatever is close to your tunnel?

Finally, how do we actually get that much power? Certainly you cannot expect the local grid to supply that much. Maybe they could design and power it with a portable nuclear reactor? That's the same order of magnitude as a small one. Can't wait for the portable river technology that will make cooling all this possible.

I guess they could bring some 2,000KW diesel generators. They'll just need sixty of them. At around twenty four metric tons per unit and a combined consumption of 30,000 liters of diesel per hour that is going to be some interesting logistics.
Based on a few minutes of Googling, I think you're thinking of a plasma cutter which creates a closed circuit through plasma, through a cut line in the conductive material, and back to the machine. This seems to be just torches which shoot out plasma at high temperature with no closed circuit required.
Join a game jam with a team looking for contributors. You'll learn new skills, both technical and managerial, and you'll have something to show at the end of it.

Reader mode of safari disables such bull
Doesn't refusing support carry an implicit judgment that the activity they're undertaking is somehow morally inferior? Why is any lifestyle choice superior/inferior to another? I'm not aware of any objective criteria that allow you to rank being a RAAM participant/heroin addict/workaholic/etc. in some sort of order, and draw a cutoff between what you would/wouldn't support. Perhaps you're aware of such criteria and I'm missing something? Otherwise it seems like you're just arbitrarily imposing your personal values system...

> Papers aren’t textbooks, the goal is to communicate what was done and what happened not inform the reader of some wider context.

And a literature review is part of what was done, always. If what you said were true, there would be no point in a literature review at all. Instead, every paper includes one because researchers understand it's an intrinsic part of research. That's what makes it research instead of just search: research is a systematic process that involves, in every definition of the process I've ever come across, a literature review. I challenge you to find an example of peer reviewed research that doesn't contain one.
Wow… and I had felt nervous about the computers in my house and business still running Windows 10 (which will be EOL in 3 years, not a lot of time for a business). But McDonalds has no problem with Vista (EOL 5 years ago). Ouch.

I read the docs too. Great docs can spell the difference between using your code and giving up or finding another solution. If you're new to a particular language or programming, code with great docs can also teach you how the language itself works.

Tabulator (http://tabulator.info/docs/5.3) is the last example that comes to mind, had to use it earlier this year.
Possibly - that Chris Riddell was born in 1962, and the publication date on Amazon for Write Your Own Fantasy Games (Usborne Computers & Electronics) is 26 October 1984, so he'd be 22 at the time. I was a huge fan of The Edge Chronicles as a kid.

> You do understand the logical error you just made, right?

No. Help me out.

You said "There does not appear to be a single non-ultra-biased source reporting this story. Which means, as far as we know, it could be entirely nonsense."

Which means that since there are no sources you like, you choose to disbelieve it entirely. Therefore, I pointed out that many stories are not covered in major media outlets but are nonetheless true. So where's the logical error?
The placebo effect to my knowledge has been demonstrably shown powerful enough even to shrink cancer tumors, so why would such a question even be posed at this point?

Not only are the costs comparable to a carbon thermal plant, the generating equipment is identical, and the cooling needs are also identical.

Solution: build nuclear cores as close to existing coal plants as possible, shut the coal plant down, and move everything from the steam boiler to the wires to the nuclear plant.

Repeat until no coal.
Why Can’t Remember the First Years of Life? Scientists Know ‘Infantile Amnesia’
Keep in mind that the people who publish a correction like this have a lot to gain from getting a lot of attention.

They succeed when lots of people say “what?! This broadly accepted idea is wrong?”

It’s the equivalent of a Buzzfeed headline, even if backed by thoughtful research. The new research may be correct in invalidating the prior experiment’s evidence but the reality is that we all know the “nudge” idea is useful at a practical level. If I ask my two-year old son if he wants milk, the odds that he is drinking milk 5 minutes later skyrocket. The same principle applies to people making all kinds of choices - from buying insurance to picking a University.

Choice architecture matters and we all know it.
Ask HN: Ethics of Requesting a Demo from a Competitor
I'm considering building a web-based system to make finding domain-specific government publications easier. This is for a friend whose organization cannot afford the cost of a supposedly similar service. However, it likely could be monetized and possibly also improved upon based on the limited information available about the existing provider.

The question is, Is it unethical to register to get a demo of the competitor's offering? I personally feel uncomfortable with the idea, but I get a lot of advice from non-technical people that it's no big deal, and I should do it.

I'm certain people in the HN community have considered or experienced such a quandry.

To be clear, I believe I know what I need to build for my current target user, but I also think this would be a very useful service to other organizations who aren't typically well funded but are working for the public good. Likely I would get some useful additional ideas from seeing what the competition does. The people for whom my potentially improved product would benefit are people who are not current customers of the competition. Of course, if I did build a better mousetrap for a lower price, it could take business from the competition.
That's not a very descriptive or explanatory article, I'd be very interested to learn more technically about this device if you happen to know or have anything.
Its not about cheap vs expensive. It's about overall incentives within the system. A read should be as valuable as a write. At the very least, a read shouldn't be completely free.
Reality = Brin might have faults but he's good at hiding them. He also founded a company that billions of people use every day , and not only that...they use all the various different flavors of Google.

Also reality = Musk has many faults and he's very bad at hiding them. But that is essentially irrelevant for people who don't have to deal with him, also there isn't a scarcity of hot girls so the animosity towards playboys like him, Leonardo Di Caprio and Dan Bilzerian is out of place.

Tough love for Musk fans = approximately 1 million people use the products/services sold by Musk companies...out of a potential audience of about 100/150 millions (those who can afford a luxury sedan).

To summarize = I'd shake Brin's hand and pat him on the shoulder for a job well done, won't try to become his friend or anything. Would not do the same for Musk because there is nothing to congratulate him (yet).
