> When you say "chosen"

I mean that neither nature nor theory requires one to choose Minkowski as the background spacetime, although it is the most popular choice in perturbative General Relativity.

I've been avoiding sign conventions and coordinates deliberately; I think they would be more distracting here, and of course the choices made have no physical implications.

(Using \eta without it necessarily meaning Minkowski spacetime is arguably an abuse of notation, if that's what you mean. :D)
I suspect you are a troll.

Of course my eyes have a log function. It's called my brain.

And how that's relevant to the simple physical discussion of your claim to ownership of all particles with which you've ever come into contact is beyond me.
Well, they made me look dumb[0] thinking that surely it wasn't the last version or they might respond to some of the points raised.

This update is terrible. Why is WebAssembly one of the most prominent features? Why do you need a testimonials section? Why is there not code above the fold? Rust is a programming language. Why would you not give a glimpse of the language above the fold.

This absolutely smacks of the kind of shenanigans and meaningless drivel all over the front-end startup world. Rust isn't some "product", and this is a generic product landing page for some generic product.

> Empowering everyone to build reliable and efficient software.

What the fuck does that even mean??? C empowers everyone to build reliable and efficient software, by handing out footguns. Rust is interesting for very specific reasons, it's not the only way to build reliable and efficient software. Fuck this vague "everyone's on board" inclusive language too -- who is "everyone"?

I'm the tech lead at a small mobile game studio, the best advice I can offer is pick a role and start developing your skills in this capacity. Main roles are tech, art, or business. If someone says design, don't listen to them, for good reason.

If you pick the business side, please be aware that you're only as valuable as the money you can raise. Of course there are other important skills, but just having good ideas isn't enough, you need to have the funds to sustain a team for the long haul.

Be prepared to survive for a few years. Game dev is an art form and like any craft, it takes years to get it right. However, one of the biggest mistakes you can make is picking one large project for the course of this time. What mobile offers is at least the ability to publish small games you can complete in just a few months. This will ultimately be way more valuable to you and your team as each successive project allows you to build upon the mistakes of the previous. If you're stuck with a large sucky project (it will be cause it's your first), you won't get the chance to do it better before it's too late.

There's so much more stuff... It would help if you were certain about the role you wish to pursue
Lots of great advice here, thanks for sharing. Regarding #4, I firmly belive that one of the best things a father can do for his children is to love their mother.

Self driving cars are expected roll out in the same time frame as this rail project. I think they change the ridership equation. The drive from LAX to SFO is about 6 hours, 3 hours longer than by HSR. But if I can work or sleep in the back I'd prefer to take the car. The car gives me more flexibility at the destination and more privacy, comfort and cargo space.

When self driving cars become sufficiently trustworthy a better solution might be a hybrid: high speed self driving car lanes.
> The point of building a platform is to create more value for your users

Sure, from a competitive perspective, that makes perfect sense. However, FB is at this point a global surveillance operation aimed at inserting itself as an essential utility in everyone's life, with the only apparent limit on their intel collection being fear of bad PR.

If you don't have enough sense to stop playing chicken with gray-areas[1] when you're big enough that playing rough can hurt those outside of the game, then you deserve to be regulated, if not attacked by regulators and sued until it really, seriously hurts, maybe kills.

I mean, what do you call it when a tech company puts serious energy and effort into hiding that they're harvesting text messages and phone calls from Android users incautious enough to trust them? Facebook is the world's largest malware infestation to date.

I think bmon just meant that renewables have more daily peaks than coal or nuclear, so they create more opportunities for battery savings relative to traditional fast start generation.

More peaks doesn't mean worse all things considered, it isn't a critique, it's just saying that battery viability is highly contingent on local power mix.
I hate to break it to you, but academics certainly do get away with this practice. You simply don't have to report the 1000 results or hypothese that didn't generate positive findings: also see publication bias.

Indeed not only is it present, but due to the various ways academia ranks citations and papers, it's fairer to say it's actually incentivised by academic culture.
Ah, very good point! I was imagining the case where some does `cargo new`, which will give them `edition=2018` automatically, and didn't consider that you could just delete that line rather than editing it. :)
It is a basic human right. Sadly one you do not enjoy. And I am sorry it is that way.

> Photos. As in pictures. Physical copies

I know where you are coming from and what point you are trying to make, but to play devil’s advocate this analogy does not age gracefully in the digital age.

Obvious counter: what about digital photos? They don’t “exist” physically, as they are only a particular arrangement of existing electrons coaxed into a particular low-entropy state.

But to take it further in a less witty fashion, it seems that in the space of a very few short years sexting has gone from “edge” to “mainstream” and people you are “authorized” to “see” IRL are now people that willingly send you digital photos of themselves in compromising outfits or various states of undress. This time they are not giving you photons but digital files, probably with the intention of them “expiring” within the near future (when the snap/what-have-you expires) or with the presumption that they either magically disappear when the sexual relationship comes to an end or with the presumption that the relationship will last forever. What then?
> Things I didn't bring into it at all.

Well it's pretty much implied. Not all industries can survive with employees working 2days/week. It would require 2.5x more employees to get the same number of worker hours in a 5 day period if every worker was limited to 2 days of work. Each of those workers would presumably be paid/compensated enough during those 2 days to be able to not only survive but also have disposable income (~2.5x pay per day in those 2 days). So 2.5x more workers, all making 2.5x pay/day each. It would be incredibly expensive and likely cause massive inflation.

The only way it might be feasible is with some redistribution of wealth.

I agree they should do it, but it looks like other researchers do sometimes get away without publishing their data?

None of the problems in the SA grid have been due to renewables.

The problems have been interconnects failing, poorly maintained transmission lines failing, the market operator placing restrictions on renewables which meant that renewables were not allowed to try to keep the lights on, and reliance of SA on electricity imported from unreliable interstate supply (aka coal thermal plants that break down or simply fail due to high ambient temperatures).

All of SA’s energy problems are due to poor regulation, poor market operation, poor maintenance, Federal interference, market gaming by fossil fuel operators, and unreliable coal plants.

There will be similar returns possible for other batteries in NSW (a net importer, thus highly vulnerable to gaming of the market) and QLD with a large installed base of unreliable coal which means increasing need for ancillary services.

Coal is not reliable to start with, and the plant currently in use is old and getting to the point of being no longer economically viable. NSW and QLD grids will need significant support services as they transition from unreliable coal to dependable (but intermittent) renewables.
That's one thing. But there's other problems:

1) certification that takes 10 years (more like 3, but ...) means you, at the very best, have 10 year old technology

2) Certified at a higher level. That can for various reasons be very different from reliable at a different level. For instance, circumstances change or knowledge advances.

For instance certification tends to take "proof" that something works. Yet the most reliable robots are pretty bad hardware, with the ability for multiple components to do the same job "most" of the time. Such a device, despite being much more reliable, is disqualified a priori in nearly all certification processes I've seen.

(needless to say, every time the things they take as proof tend to be ... less than proof)

Plus we've all been in a company having this discussion. "For the price of this one 'reliable' server we could have 20 normal ones, and they would be a hell of a lot more reliable together. Hell, just give me 3 of the cheap ones and I'll make it more reliable". And we all know what the boss's answer and the resulting reliability was.

3) You assume no regulatory capture (or outright dishonesty on the part of government employees and/or lawmakers)

I don't understand why Microsoft didn't partner with Firefox instead.

Strategically it would have been a super win - lots of good will value to gain, a way to keep themselves and others less reliant on Google, and perhaps even push/use Firefox as a poster child GitHub partner for further value. What gives?
Managers want to literally see what they’re spending all that money on.
Fair enough, but there is no way to change to that even if I consent to send my keystrokes for auto completion.

Also, Firefox has auto completion on by default on its default search engine, which is Google no less. So I'm not sure why this topic is about privacy other than purely technical.
The only thing I miss in Firefox is the ability to Chromecast directly. It's useful.
I would normally not repsond that long, but your account is old enough to not be a troll.

Do you really mean what you say here? I am talking about it being morally wrong to make pictures of you to share with someone else if you do not consent. You brain does not have a print function.

Is this a misunderstanding because you still havent realized that I am not talking about photons but photos?
This is really cool! I oftentimes use repl.it to explain a concept or something to friends learning programming, this will be really helpful!

Since people are recommending other multiplayer-stuff I'll recommend Live Share for VS Code [0]. It is so useful that I've shifted to VS Code (with my teammates) for some projects just for the live sharing. I've tried Floobits (to be able too keep my regular editor), but that seems much more elaborate with persistent "projects" which is not really a fit for my more casual use case.

So, this article has some valid criticisms, but why is this the case? Why does it seem like modern America can't manage any public works projects without them taking twice as long and costing twice as much as projected? Is it regulation? Lack of work ethic? Graft? It seems like a major problem.

Normal car batteries are filled with sulfuric acid and lead plates. Obviously, you can't just dump that.

The li-ion batteries that power EVs don't have acid. The majority of the chemicals are actually totally innocuous- the carbon, plastics, electrolytes and about half of the metals are downright boring. Steel, aluminum, copper, polypropylene, carbon- lithium was in all the water you ever drank. I wouldn't drink the electrolyte, but it's basically just fancy grease/oil. The only two dangerous ingredients are nickel and cobalt- they aren't as bad as lead, but they aren't good either. They're also the easiest to extract and the most valuable.

To recycle a battery, you dump it into a shredder and then into water. An electrochemical process is used to suck the metal off, a lot like how they plate metal onto things (but in reverse). The leftovers are strained out, ground, and eventually burnt.

Cars may become self driving, but that won't change the fundamental efficiency problem in that you can only fit so many people in a private car.

What you're describing can already be done by calling a Lyft, albeit at slightly higher costs than a self driving car.
As someone who voted for this project, I'm really bummed with how it's actually turning out. The actual costs are so much more than what people voted for, yet no one's being held responsible.

At the same time, I don't really have a solution to this problem. We need to invest in large scale transportation initiatives for the future — projects just as forward-looking as BART once was. Yet not even NYC can pull it together anymore to extend their subway lines on budget and on time.

Worse, every time this happens, initiatives like this become harder and harder for voters to consider.
For all the people talking about consent in this thread... I just want to point out that the Civil War significantly predated the phone camera, modern digital cameras, or even the first film point and shoot cameras.

We call it “posing” for a photo because they literally had to pose without moving for at least 15 minutes (and probably more in the mid-1800s).. just like you would have to remain in-place holding a pose for hours while having your portrait painted in the eras past.

Interesting fact: it’s also the reason why photos from the 1900s all feature the same grim countenance and subjects look like they’ve lost all interest in life - it’s not possible to hold a friendly face for the duration of time it takes the film to expose.
3000 cycles “lifespan” but most of the degradation happens in the first couple of years with the rate of degradation about 3% a year, capacity still remains and the product will still have significant capacity in 20 years.

As opposed to say a synchronous converter which requires annual downtime and continual replacement of parts, and (being limited by inertia) can’t provide the same stability and support that a battery can.
This. Especially if you use hotkeys for opening container profiles. Since the FireFox UI doesn't allow for container profile reordering in the UI you have to rebuild your profiles in the correct order (because hotkeys are mapped to order of creation based on numeric value) and reselect the appropriate icon and color to match the profile you're used to. Right now containers are not a welcome citizen with regard to Sync. I really enjoy containers but they need to be front and center and a first class citizen in the profile with Sync.
Do we know what hardware each was using? Aside from time, s criticism of the previous AlphaZero/Stockfish match was that AlphaZero was using a tremendous amount of TPU power while Stockfish was running on, essentially, an average laptop.
I’m curious... AlphaZero seems quite good at understanding closed systems, with deterministic rules.

People seem to think this will generalize to open systems, with no rules, like war and politics... why?
HSR is not supposed to take you from A to B

HSR is supposed to line the pockets of Democrat donors for decades, and it surely will

By time it is done, every potential rider could have been given a private jet for less cost
That should be reflected in the projections, which it apparently isn't.
I used to support the HSR project on the grounds that connecting the state (both LA / Bay Area and the Central Valley towns) would yield long term economic benefits due the increased flow of people within the state. Decreasing the effective distance between people by making travel faster and cheaper has a lot of value in the information economy. Nothing beats face to face communication.

I now no longer support the project due to the large price tag. I don’t believe the convenience of HSR over air travel is worth the cost of this infrastructure investment. We could get way more value out of investing in building our local public transportation and expanding the highway network.

Maybe if we went back to the drawing board a reasonable HSR plan would be possible (this article certainly provides good areas of improvement). Until then, we need to stop forging ahead.
Make it a ritual to pause and think before any significant decision, so you do the smart thing. Eventually it'll become routine.
A lot of it depends on the properties of the language itself. Traditional C-style imperative code involves many short statements each doing one small thing, one expression per statement, one statement per line; this makes it simple to punt on wrapping long lines (which is 90% of the difficulty of writing an automatic code formatter). Go inherits this "tall-and-narrow" idiomatic style. But other languages, especially ones that try to encourage fluent APIs, will often have several expressions within each logical statement, leading to fewer lines of code overall but more action on each line. In these languages it tends to be idiomatic to break the statement across multiple lines (usually at method calls), in which case an automatic code formatter's job is to do this operation manually.

While this article finds an issue with the way the Tejon Pass route was eliminated in favor of the Tehachapi Pass route, Tejon Pass route would skip a station in Lancaster/Palmdale, which would be a mistake. As the article acknowledges, these are rapidly growing exurbs that are refuge from the exorbitant land prices in the LA Basin. There is existing commuter rail service between there and Downtown LA, but a HSR is a significant level-of-service upgrade, and offers connections to Bakersfield and beyond. The fact that a rail line offers connections between many points with the same service, while air service must fly at least as many services as there are destinations, is lost on these commentators.

That being said, there are many facepalm-worthy decisions made by CAHSR or by others early on in the process, like an extremely sweeping curve on a long, expensive viaduct just outside of Fresno station [1], or the barely-realistic journey times written into legislation that drive up cost. Another is the choice of the torturous Pacheco Pass over the easier Altamont, or even going around the mountains following the Strait the old rail does. Besides, there's no point to pining after LA-SF rail traffic when airports are perfectly fine between those two. But what about LA-Bakersfield? Modesto-Sacramento? SF-Fresno? That's where a train helps. And to do that, all you need is a train that does comfy, European speeds like 100 mph, instead of a painstakingly-built one that does twice as fast.
