OK, then it makes sense.
This blog post has a much more in-depth analysis of the cost of overflow checking:

https://blog.regehr.org/archives/1384

The tl;dr is that (on x86-64) the additional branch to trap has almost negligible cost (processor already sets the flag on overflow, jump is always predicted), but it completely breaks vectorization and loop optimizations, which significantly impacts certain benchmarks.

Not again. Every 5 years or so, a story like this makes the news. People will walk up to me, ask me if I have already heard about this ground breaking development, and if I am already registered to receive my upgrade!
Resolution is as low as fuck, and risks attached to such an upgrade are pretty crazy.
I wish the media would stop using these kind of stories for clickbait.

Will be large scale batteries very soon, as the grid storage market is growing at an exponential pace.

As battery prices fall, entirely new markets open up. Right now batteries beat the cost of natural gas peaker plants. In Arizona, where solar is so cheap, batteries are becoming economical for correcting the duck curve in the evening.

Germany has plenty of wind overnight.

It's not like an entire country's grid will ever be powered by a single source of energy, so I'm not sure what the point of comparing hydro capacity to total energy consumption is.
Second that - frequenting between OZ, Singapore and Japan I'd always prefer A380 against 777/787. It's unbeatable beast when it comes to long haul flights.

This assumes you can extrapolate the interest of ETFs. There are some reasons why it might not:

- Index ETFs are becoming a huge part of the market maybe leading to unexpected results.

- We’re in a completely different situation of monetary policy. Japan is the most similar we can compare to and there it lead to a stagnating stock market.

- if the Fed decides to change its monetary policy in some years there will be significantly less money available for the stock market

- the economic position of the US is changing dramatically compared with the last 50 years.

It can be much better than the confirmation dialog, because it's meant to be implemented in such a way that you can get on with the rest of your work while the undo-countdown is ticking.

From personal experience with gmail's fake undo, in terms of things sinking in, it works almost as well as regular undo for me; and not like a confirmation dialog (which doesn't work at all).

So there's less friction, there's no extra click you need to make after ten seconds. And, also from personal experience, the force-delayed confirmation dialog I've used (I think in Chrome and Firefox for certain actions), don't seem to lead me to thinking at all. At least not any better than a regular confirmation dialog.

But in any case, all these are empirical questions, and it would be interesting to run a little user study with the different options, instead of endless speculation.

Common GC speak.

Traced references are tracked by whatever form the language offers automatic memory management.

Untraced references are a kind of safe pointers, basically the memory they point to isn't tracked by the GC/RC infrastructure and they are managed in some form of manual memory management, and can be used as part of unsafe code for pointer arithmetic.

The languages then provide means of converting between both worlds, naturally it always requires making use of some form of unsafe code block.

I really think the economics behind nuclear traditional power plants are a bit screwed. It takes years to build and costs order of magnitudes more than a gas turbines. In addition gas turbines are particularly well suited to be turned on in a mater of minutes whenever there is peak demand. And you still need power when there is no wind or no sun.

Unless there is strong support from government, Nuclear Plants can’t happen.

I’m really putting a lot of hope in the next generation of mini self contained nuclear plants. I think Bill Gate is also looking into that. These have the potential to be successful both for the planet (get rid of gas turbines for peak demand when renewables fail) but also economically (easier cheaper to build).

In imperial/US (which are not identical) you simply think of it differently, using a quarter mile, half mile etc. Using rational fractions (1/2, 1/3, 1/4 ... 11/16 etc) are very simple and natural in that system. Having lived in countries that use on or the other, or have transitioned (and having been born before currency decimalization) I appreciate the strengths and weaknesses of both systems, and use each in its “natural” mode, just as I don’t speak a second language using the grammar of the first.

Metric is not “automatic” either. One year in university I took three classes that happened to be in the same classroom. One was in cgs, one was in MKs and one in ASME units (US customary units plus mils). Three different subject domains. It didn’t feel odd or complicated.
So on my machine it's

0.72 ns/int (+/- 2.5 %) vs 0.90 ns/int (+/- 2.5 %)

for normal cases when no overflow/traps actually occurs.

When an overflow/trap occurs, a possible severe bug, it's

0.74 ns/int (+/- 2.5 %) vs 9.12 ns/int (+/- 2.1 %)

I read the sourcecode and it seems the array is 1000 elements (with random elements). If each sum supposedly need 0,1ns then the whole process is around 100ns=0,1 ms. I do not think you can do benchmark on these timescales. Then the algo is repeated on the same data 40 times and averaged. This also doesnt help too much.

So the first run puts everything in L1 cache and then it runs much faster.

Anyway usually anything below 10ms is random, and one should go ar least for 1s (or even more).

We are building our massive energy stowage factories. Car companies are scrambling to create supply chains. This is happening really fast.

Since I did not estimate the amount of energy to store for a day, I don't know why you think I underestimated it. If you think we will turn off all generation for an entire day, ignoring solar and wind and hydro resources, and just run off batteries for no good reason, I'm not sure why you would think that.

What is the real resin that Germany is building gas plants? And how do they justify new gas plants, economically, in this day and age? They will be stranded assets in a few years, so it sounds like corruption or ignorance. Surely the economics can't be so different there than what exists in this Rocky Mountain Institute analysis of US costs, where we have super cheap gas?

> We find that the natural gas bridge is likely already behind us, and that continued investment in announced gas projects risks creating tens of billions of dollars in stranded costs by the mid-2030s, when new gas plants and pipelines will rapidly become uneconomic as clean energy costs continue to fall.

Each individual passenger would have more takeoffs and landings, and travel more miles, but in total I would assume the airlines flies less miles and has less takeoffs and landings. The number of flights is O(N) instead of O(N^2).

Indeed you don't want to mix and match too much. Programmers need a ramp up time and teams need time to have cohesion.

787s and 350s are quite large, so this makes sense.

Point to point is doing fantastically. They just use smaller planes for it, A320s and 737s. Even after the whole MAX debacle the MAX order book stands at 4,129 planes, far ahead of the 787 and its 1,507 planes. Airbus has a similar story with 7,445 A320neo family planes vs 930 A350 orders.
I agree with you. However Xi is only one person, there is much larger power structure behind him. And you are absolutely right, Jiang and Deng have much more experience with the west and 'modern' at their times. As for the younger generation I couldn't really blame them; the ones who are interested in the outside world already did so. I believe there are substantial proportions of youth who have a balanced world-view. But given the education structure and absolute large population base you won't see them represented. I couldn't give much credit for chinese students abroad, since large part of them are quite privileged and ignorant(depends on how they were brought up), the rest were the poorer, sponsored students, they would naturally be very nationalistic.

Interesting tidbit on the importance of keeping a day job:

I think that for me it’s been very useful to exercise other activities, such as working in a bank, or publishing even. And I think also that the difficulty of not having as much time as I would like has given me a greater pressure of concentration. I mean it has prevented me from writing too much. The danger, as a rule, of having nothing else to do is that one might write too much rather than concentrating and perfecting smaller amounts. That would be my danger.

It's worth mentioning that x86 CPUs had a single instruction overflow test that would raise a hardware interrupt in response to an integer overflow. This allowed for extremely low cost integer overflow tests.

Unfortunately, this capability was deleted from x86-64 and we're now stuck with either accepting the risks of integer overflows or suffering a performance hit to test for them by using multiple instructions.

Another extremely useful instruction deleted from x86-64 tested if an array access was in bounds. Determining how many buffer overflow exploits could have been prevented if this instruction was widely used--and carried over to x64--is left as an exercise for the reader.

That's simply untrue. Iceland for example is already 100% renewable. Other grids with large installed hydro generation (eg New Zealand) could move to solely renewable with the installation of more intermittent generation and transmission infrastructure.

Yes, most grids still rely on non renewable resources. But that is simply a relic of the fact that they were built that way. The existing examples prove it's possible.
Right, but that's only really a problem because affording a lawyer for any amount of time is ruinously expensive. If lawyers were cheaper (or litigation much faster), even fighting the government would be affordable, even if it would be an awful experience in other, non-financial ways.

Pro-bono stuff is a great and honorable tradition, but it's not enough. I worry about any system that depends on poor citizens being sympathetic enough to receive free legal representation as a charity from otherwise unaffordably expensive lawyers. It's clearly superior to locking all poor citizens away from legal representation, but it's not anywhere close to sufficient.
It's a shame they caved and settled. If anyone has deep enough pockets to fight something like that, you'd think it's Google, even 10 years ago.
