> I prefer to think of a reference to a type as a type in its own right separate from the borrowed type. Looked at that way, Rust does have affine types.

The reference type is a separate type, but the & borrowing operator is a use of the original path. You can borrow (i.e. use) the same path multiple times before it is moved or implicitly destroyed.
It could still be an artifact of something else, e.g. differential digestion associated with age produces length and GC artifacts.

I've been working on my own encrypted and de-duplicated backup solution using libsodium. It's early days and progress is slow with limited spare time, but it works well enough for my own use already. I wanted to avoid any closed source or even lesser-used open-source encryption.

large, and very populated, parts of the world rely on slow ice-melt from winter snows on mountains (California, India). Global warming may mean that that slow-ice-melt won't be so slow any more, and that can mean possibly flooding followed by drought.

What do you do if you don't want to fly a particular plane, but both direct connections for a trip you need to make are flying it?
If the price was the only problem, you'd still expect to see people playing draft regularly, at least in the interim, especially since there are free drafts you can play. But there's more wrong with this game than just how they priced it.

It may be that RNG is actually less of a factor in Artifact than in other similar games, but boy does it FEEL stronger. Every turn in a CCG lets you draw cards, and maybe you don't get the card you need, but maybe your opponent didn't also, you don't know, but instantly. But in Artifact, every turn drops creeps in the lanes for both you and your opponent, so you can instantly see if RNG has blessed you or cursed you.

It doesn't even feel great to win when RNG is on your side sometimes. Your opponent has built a huge bruiser in an early lane that will just demolish you there and win the game, except a creep spawns in front of him, blocking all that damage. I mean, I didn't do that, that was just luck. I didn't make a good play or build a good deck to get that one extra turn, I just got lucky with creep spawns.

Sure, there's definitely more around it that got me to that point where I could get lucky, I understand that, but that other work doesn't feel emphasized, the last-second luck does.

And the biggest failure of the Artifact team isn't in the design of this, it's the hubris of not listening to the players complaining about it. It doesn't matter if you build the fairest CCG in the land, if it feels like swingy garbage, nobody's going to play it and it's going to fail. Standing above in their white tower, yelling down "but the math says you're wrong" doesn't matter if nobody's having any fun.

That doesn't work as well because borg needs fast local access to the files in order to do deduplication etc. If you use SSHFS, it's going to be much slower, IIRC.

I just pick one thing outside of work I want to achieve at a time. I don't actually care about the results - everything that's in my brain is ash in 60 years time anyway - but I enjoy the feeling of self improvement. But I don't need to do that much to get that feeling.
I would say that when people say “khakis” they actually mean “chinos”. Chinos are the type of pants, khaki is the usual color (a quick google search will corroborate!).
Fly with a different airline? Don't fly at all? Take the train?

I already use sites like seatguru.com to work out the best seats on flights - I guess I'll now be checking to see if it is a boeing plane or not before booking.
Would that not have all the companies that bought the MAX asuming that they would not have to retrain their pilots asking for some $$$ or even cancelling?
It’s just a color. Usually beige-y. Your boss wants you to wear something that looks not casual but not like a suit. That’s all that matters.

I didn't check out the paper in detail, sounds like the shape of the correction surface depends on the distance to what you're imaging? Does it do so in a non-trivial way? If so, this sounds a bit more like an academic victory, no?

> holding on to Greenland is a bad idea

What do you mean "bad idea"? It's habitable land, there will not be more of it on this planet (except rather small landfills, and Denmark more than others knows the price of it).
There was one paragraph:

> The quake caused further damage to a U.S. weapons testing facility outside Ridgecrest, the Naval Air Weapons Station China Lake, although details were sparse early Saturday. “NAWS China Lake is not mission capable until further notice; however, security protocols remain in effect,” the naval base said on its Facebook page after the latest temblor. The installation is the Navy’s largest single landholding, sprawling over 1.1 million acres, an area larger than Rhode Island.
The parent's ROB is the reorder buffer. AIUI it causes the instructions to be retired in order (with exceptions stored until retirement, then exposed). The original question, though is how a particular u-op is mapped back to the original macro-instruction, so we know what macro-instruction excepted.

And I don't know. I guess is if each u-op is tagged with the instruction address within the process, that would do, but that's carrying around at least 32 bits, which is quite a large tag.

Alternatively tag indirectly, which is more likely (you can have maybe 256 instructions 'hot' at any time so an 8-bit tag on each u-op pointing to a 32 or 64-bit table entry (edit: holding the actual address of the macro-op). And the window for the ROB and the other thing that does instruction issue, is ~200 instructions, so that sounds more plausible).

All speculation on my part though!
How can it? Using what standard? America's? Australia's? Where do you even get the impression they should have to and that it's so out of this world that they don't "have to"?

They can’t block sites when going via a Wireguard VPN surely?

Where are you exiting?
Presumably the federal government is taking care of China Lake and doesn't want anyone to know about it. I don't see why they would invite the press onto a classified weapons research facility just to catalog earthquake damage. When you're a wealthy landowner housing thousands of explosive munitions in an active fault zone, presumably you build it to withstand earthquakes.

But yes, AFAICT from the maps, the epicenter was basically right under China Lake.
As of today, chances are that there will be actually less inhabitable land available due to ocean's rising. And Greenland could be much more useful after it's ice is melted.

Update: it's actually as large as Western Europe from Spain to Poland, less UK. See https://thetruesize.com/

No the biggest issue wasn't the pricing structure.

Artifact was just not fun at all.

I've been playing a ton of MTG, HS, Gwent, MTGA, bought Artifact, played 5 hours, never touched the game again.

It's overengineered, unnecessary complex, too slow, too long, too random and at the end exhausting, frustrating and not that interesting.

Most people played one or two games of Artifact a day then moved too something else.
I don't.

Longer answer is that I just pick whatever I feel like working on whenever I have free time. I probably have personal projects to keep me busy for years at this point.
Makes sense, I wonder if it would be feasible to reduce the number of genes to be over expressed by correlation with known medical conditions e.g. cardiovascular disease, kidney disease, or other cosmetic signs of aging.

There are a lot of people in this thread putting down the idea of an autonomous plane, but frankly, as a pilot it is a much easier environment to automate than driving.

In the world of instrument flying there is very little to hit which isn't clearly charted, you have an external navigator to keep you clear of most other planes (Air Traffic Control), and the landing environment is kept very normalized by the hard work of the FAA. This is orders of magnitude simpler to pull off than self driving cars, and it might save the General Aviation industry.
Good point: my assertion in grandparent that "Rust does have affine types" is wrong.

Do you agree with my belief that it is significantly less likely the borrow checker would've been invented if programming-languages researchers hadn't paid a lot of attention to linear and affine types? Even though a Rust coder can take as many non-mutable references to a location in memory as he wants, there are certain operations (e.g., move) that the coder can only do once to it, and the inventor(s) (probably Graydon Hoare) of the borrow checker must have explored that part of the design space extensively, and it seems to me it would have been very non-obvious that it was worth exploring extensively to someone not influenced directly or indirectly by Girard.
It looks like they have already recovered everything.
My understanding is that centuries ago in Latin America "madre" became an euphemism for "madame of a brothel", while actual moms are called "mamá". In Spain it carries no such connotation.
Awesome article, wild equation
Last minute aircraft swaps are pretty common, so you would have to have plans for that also.
The assumption that programming is deep work seems like a self-serving prejudice. Which parts of it are automatic will differ from person to person, but I imagine that a substantial majority of programmers will spend a substantial chunk of their programming work doing things that are shallow to them.
The FAA doesn't care about the name. They can require a type certificate specifically for the 737 MAX series, separate from the 737 NG series.

And a type certification isn't the only way to require additional training. For sure there are meaningful differences between the 757 and 767, despite sharing the same type certification, and pilots do go through that difference training. There are numerous examples of this.

Where Boeing probably wants to be, is in the vicinity of the regulatory distinction between the A320 and A320neo. It seems really unlikely to me that any 737 NG to 737 MAX transition training burden, is going to approach that of 737 NG to A320neo transition training.
Ask HN: Which issue-tracking system for staff of our academic research group?
We are a small-to-medium-sized academic research group (~ 15-20 PIs and ~ 45-60 trainees). Which issue/request-tracking system should our system-admin and technical staff adopt?
It depends very strongly on how you used WPF. It had many footguns, due to a foolish decision to seemingly support the expectations of winforms developers.
> The problem with the Max is that Boeing favoured the major airlines that wanted 2010s technology in a 60s airframe. But guess what, that doesn't work, in the same way you can't turn a Thunderbird into a Tesla by "just plugging a new engine".

No, the problem with the plane was that Boeing engineered a crappy solution to a problem they had.

There were 3 major problems that I am aware of.

1) A powerful(flight control wise) automated system that relied on one source of sensor data when multiple are available.

2) The switches that disabled the automated system also disabled all electronic control for the elevator trim, making it much harder for the pilots to recover from an out of trim condition.

3) The normal elevator controls are not enough for the pilot to overcome the out of trim condition so pulling back on the yoke as far as possible would not pitch the plane up enough to regain altitude.

The only way to recover from this type of situation is to momentarily pitch the plane further downwards to take stress off of the elevator trim so the manual controls are easier to operate with your hand. You would have to do that enough times to get the plane back into a stable position, this is not always possible when the plane is already at a low altitude.
The paper is from Nov 2018, and is easy to find online. It’s a pretty amazing result; the examples they give in the paper are for some reasonable shaped primary surfaces and some really neat “exotic” stuff. The solution actually admits aberrant free solutions for any geometry that doesn’t include self-crossing rays. So, some of the ‘weird’ examples include a Bessel-function cross section, negative index of refraction, and lenses that focus at negative infinity.

The author’s have a paper from March 2019 (in arXiv) that uses the result to build some novel telescope geometries.

Well said. You need downtime too.
If they used slave labor to increase profits, that would also be a competitive advantage, yet it should be disclosed since its materially disgusting. I don't see that if they were pumping out massive tons of CO2 or not, that should not also be disclosed.
Someone mentioned dog mode in a Tesla, but that’s not the only feature that does this. Dog mode or Camping mode is for keeping the interior at something around 20c or whatever you set.

from reading your comment it sounds like you just don’t want the interior to ever get over 35c, which is exactly what the Cabin Overheat Protection mode is. Basically this is a set it and forget it setting that ensures the inside will never go over 100F. You can choose to use ac which kicks it on and off every so often using minimal range, or you can choose for it to only use outside ambient air, granted it if it’s 48c then you are only getting as cold as that.

+1 to everything you said. I can see the features of this site supporting a quick view into stuff that's going on, but the design needs a lot of work.

One thing I wish: I don't want to go to a separate page to see the few facts, especially for the top stories.
I see what they mean then. I read the question a bit too fast.

I was mostly assuming that the issue of the operation reserved a spot in the outstanding buffer which would ensure sequencing of the write or commit after execution which would walk through the buffer in sequence.

But you're right that there are still more questions to how some of that data is tracked through the pipeline.

What's with this need of using virtual machines for almost everything? Why would I need a virtual machine to compile tmux?
Yeah, that's what I was afraid of and I think I got lucky. The big thing for me is that I don't use eBay much but I'm getting married soon and my fiancee is moving a very far distance and she will need eBay to get decorations and such to help make her feel at home. I hated the feeling of inconveniencing her over some weird glitch that I was powerless to fix.

> why is a strong table to be looked for inside, to get underneath it?

Modern buildings don't usually completely collapse ("pancake"), and being under a sturdy table can absorb the weight of partial collapse: as an example, an interior wall collapsing onto you. See [0].

> I would imagine basements are bad to be in, is that so?

All I know about this is that having a (code-compliant) basement makes the entire house more resilient, but I couldn't find anything about being _in_ the basement during an EQ being good or bad. Know that basements in low-density structures are quite scarce[1] in Southern California, though -- I've lived in LA for four years and don't remember ever being in one, except in large apartment buildings.

Don't try to get out of a basement if you're in one when an EQ hits. Most injuries are a result of people breaking their ankles and legs trying to move while the ground is shaking.

> I would imagine upstairs is a bad place to be too, right?

It's a tradeoff. In the event of a structure collapse, you have further to fall but less structure to fall on top of you.

> does the ground really split underneath your feet?

Yes, if you're straddling the fault line and standing near the epicenter. (You won't be doing that).

There has never been a confirmed case of someone falling into an "earthquake chasm", but it might be something to worry about if you're a cow grazing in a Bay Area field[2].

Take a look at this study[3] of the 74 deaths caused by the '94 Northridge EQ. It's the best data we can use to project what would happen if a major EQ hit LA today.

DNA is a problem because it's presented as proof to a jury, who convict.

From the beginning, Sutton and Adams denied any involvement. They both had alibis, and neither of them matched the profile from the victim’s original account: She’d described her assailants as short and skinny. Adams was 5 foot 11 and 180 pounds. Sutton was three inches taller and 25 pounds heavier, the captain of his high-school football team.

The DNA evidence was harder to refute. Having seen enough prime-time TV to believe that a DNA test would vindicate them, Sutton and Adams had agreed, while in custody, to provide the police with blood samples

Reality is that DNA evidence overrides actual evidence time and time again, and people are wrongfully sent to jail, have their lives ruined, and even die, because of it.

The same thing will happen with facial recognition, gait, etc.
