40% efficiency is great for a laser, and 40% is great for photovoltaics so that is 16% end-to-end at best.

The Us Govt is working on laser satellites to beam power to earth anyway:

https://www.energy.gov/articles/space-based-solar-power

The Gerard K. O'Neill proposal of beaming microwaves from space gets revisited from time to time.

The solar array looks better and better because it can be something like a space blanket with a film of semiconductor evaporated onto it and is so lightweight it might be affordable to launch the materials from Earth.

This problem affects the microwave link

https://en.wikipedia.org/wiki/Thinned-array_curse

and probably means the transmitter is a separate space blanket with an antenna array printed on it. It looks less good.

All of this tech targets a market (terra firma) that has the most competitive energy markets in the solar system. People are struggling with how to fuel airliners and I wonder if an airliner could have enough stored energy to climb from JFK to 40,000 feet and then pick up a beam to cross the ocean.

It actually seems like a really cool idea as a trainer for "non-UI-oriented" developers (that end up building UI anyway) -- minus all the subjective and dark pattern stuff.

Early in my career I worked with a really great graphic designer. Up to that point, I thought I was "decent" at doing UIs, as I was proficient in the technology (HTML/CSS), and could take a sketch/mockup/photoshop/whatever and turn it into something usable. We were basically building custom templates that worked on top of a custom CMS/shopping engine (pre-Wordpress/etc), usually matching some existing customer branding, so it wasn't exactly 1:1 from design to implementation.

What consistently amazed me was that then the graphic designer would take what I did -- even just doing minimal modifications like adjusting spacing/sizing/color -- and make it look 10x better. I quickly learned that my design talent was severely lacking, and that Photoshop/HTML/CSS/etc skills are totally independent from UX/design skills.

I still think there's lots of programmers that haven't experienced this type of thing and believe being good with the tools == being good at design. Systems like Bootstrap make things a bit more interesting, because it becomes easier to fall into the pit of success, but it doesn't substitute.

A good "game" like this seems like it would help to break the mindset of some of these programmers because fundamentally once you start recognizing things like mixed icon styles, misaligned elements, or inconsistent font styles, you really can't un-see it.
It was already solved.
Helium instead if hydrogen.

"Despite a U.S. ban on the export of helium under the Helium Control Act of 1927, the Germans designed the airship to use the far safer gas in the belief that they could convince the US government to license its export. When the designers learned that the National Munitions Control Board refused to lift the export ban, they were forced to re-engineer Hindenburg to use hydrogen for lift."

I'd still suggest that sharing your keys by default is ... a bad idea. Sure, fingerprints help, but there's the chance of accidentally or maliciously being redirected to a rogue server.
Yeah, kind is a good compromise. It's more than I want and it does take some time to startup, but it's pretty lightweight and very accurate. Because everything is running locally you can use tools like `perf` to keep an eye on things you're running on k8s, right from your usual workstation. I like it a lot.

The CRI plugin sounds like probably the right thing to do. Everything is real up until actually running stuff.
Yeah, I did make HN worse with that comment, didn't I. Thank you for the reminder.
You mention this, but I want to clarify that you only need reference counting due to using only std, not due to limitations in the language.

Scoped threads are available in crossbeam, and they're pretty great, as sometimes it's convenient to borrow something from the stack.

Here's how I'd write that with scoped threads:

let my_string = Mutex::new(String::new());
crossbeam::scope(|s| {
for _ in 0..10 {
s.spawn(|_| {
let mut guard = my_string.lock().unwrap();
guard.push_str("some characters");
});
}
}).unwrap();
Absolutely, and this has a flip side: when you try to articulate the actual harm, sometimes you realize there isn't one. And then you can learn to calibrate your own perspective about what's truly a problem as opposed to just a personal annoyance. Which lets you focus your energy and communicate more effectively.
I'd say somewhere around 50% or more of Americans are pretty much understand that the cops have accumulated fairly unanswerable power, that something should be done about it and that nothing will be done about.

But another 30-40% of Americans believe cop movies/TV and think cops need to be able to shoot first and ask questions later 'cause of armies of "bad guys" armed with machine guns.

I think white just continues moving the king toward the center -- if black plays waiting moves, white can bring the king to c1-d1-e1 and then shuffle the king between e1 and f1. Eventually white will sacrifice the rook in the same pattern as the main line, and then play Ke2 -- there's no "wrong" square for the white king to be stuck on such that Ke2 would be unreachable, so black doesn't gain anything from the extra waiting moves.

It depends on the subject, how the CEO is known to react (perhaps the CEO is not from here), a trainee might hold back a little bit more, and more such factors do of course play a role.

Our organisational structures are generally just as flat as our landscape, which might help promote more opportunities for people to speak their minds to upper management. I don't have data on this though.

A distant relative of mine always said his business would have never started making money if it weren't for the Polish ladies who worked in his factory complaining so much about their work areas. He had his lunch in the general cafeteria together with everyone else whenever he could, and that is not uncommon here.

Edit: We also have a concept called "medezeggenschapsraad" or "ondernemingsraad" (depending on context), which is a kind of employee panel with decision making power that businesses of 50 employees and up are required to have. Unsure if this is unique to the Netherlands though.

It's pretty well known that for lower level offenses (traffic, summary, etc) the system is a racket. You pay more to defend your innocence than it would cost to just pay the fine. Most states restrict public defenders to those who have low income. Are there states that will reimburse for legal fees if found not guilty? The ones I know of do not.

I don't know what you would call it, but I don't think "justice" should be part of its name.
I hate this stupid distinction so much as well. The idea that you have to follow artists instead of seeing the artists based on your liked songs or albums is so dumb.

Oops, I made that more confusing by trying to note everyone was a Palestinian when the place was called Palestine. By "non-Jewish Palestinians" I was trying to refer to the predominately Muslim and predominately Arab group that we now just call Palestinians. There was and still is a population of Christians in the area and there presumably was some larger population of foreigners in the area when it was under foreign rule. I edited that comment to clear things up.
The limits of formal systems are nowhere near being approached by law, which is generally pretty simple but written in obtuse language or full of exceptions that exist purely because of the fact that its very hard to change laws. Legal communication is precisely the opposite of efficient. That being said, some types of law are obviously less amenable to being described in formal language (like laws concerning murder or situations involving complicated human - human interaction). But that is absolutely not true for the average contract , which constitutes most of the legal industry's revenues and time. In that case the only problem is that laws are pointlessly complex. As another example, we'd all be a lot better off if taxes were formulated as a program.

I believe they distributed around 70% of the coin supply to open source developers (I think only a small percentage claimed so far). The names are sold in auctions and the coins are burned after the winner is declared (I understand that early adopters will still benefit from that).

It's decentralized, and ultimately, users will decide how they value those names, though. So, for example, they can put them under dot-hns or prioritize ICANN TLDs in case of a name collision. Some existing TLDs may decide to claim their name if they disagree with a centralized root. IMO, It's flexible and pretty experimental for now

How I Learned to Stop Worrying and Love the Lab-Leak Theory
As we've already established, since Israel can and does already bomb and slaughter Palestinians wholesale with the use of their tech, taking the ability of Palestinian suicide bombers to launch their own attacks is basically giving one side the upper hand and helping them in their genocide.

It is just plain old stupid to continue to allow this tech on the road.

Truth is we will never have safe self driving cars until we have "Smart Roads" that inform the cars of what's happening on the road around them and car to car communication that inform all the cars around them of what's happening and Tesla cannot do that all by themselves.

So the truth is what Tesla has now is nothing more than a sales gimmick, and it's a deadly one when the "driver" is stupid enough to believe the car can safely drive itself, and it's proven drivers are that stupid now, but that shouldn't surprise anyone at all. We have all kinds of proofs of that dating back to the Model T.

Tesla cannot have it both ways. They can't hype the car's amazing abilities to "drive itself" and tell user's not to press the button to engage that tech because users are just as stupid as Telsa for hyping such bullshit.

And when a Telsa runs into an emergency vehicle on the side of the road with its emergency lights flashing that is a pretty solid and grand example of how stupid Tesla's tech really is.

That's not the same as saying their tech is not amazing, as automotive tech goes it's astounding, but it's no where near safe on the roads right now and it will never be until those criteria I mention above are integrated into the tech.

In the meantime I'll just try to avoid them like all the other crazy drivers on the road.

I was under the impression that by "fail" they meant "fail to create economical supersonic flight". While sending passengers to their deaths in an unsafe aircraft would also be a type of failure, I don't think that's what was implied here.
The author of that article makes some claims that you should give some critical thought to:

Some are pretty obviously wrong:

- they say the virus hasn't mutated to become more suitable or transmissible in humans

- they imply the first cases of COVID-19 were hospitalizations and imply that asymptomatic spread of the disease is not possible

Then also the article claims that science hasn't tracked gene mutations of the virus that took place in bats. I think that has indeed happened.

The logic of the people they blame us contradictory too. They say the base DNA could have been concealed by making a novel base but then they say by that this was a researcher doing public, documented research, which suggests they would indeed use standard practices and the signatures would be there.

> This tutorial will discuss advanced packaging technologies that enable performance and density improvements.

I'm interested in advanced packaging. Does anyone know anything about it? My impression is that BGA, MicroBGA, CSP, WLP, Flip-Chip are the evolutionary dead end of packaging, you can't really find a denser way to put a chip on the board. So instead, you put more things into the package or onto the interposer, and for the user, the new "module" can be used just like a chip, this is the System-in-Package approach, such as integrating the chiplet and RAM to a processor, or stacking multiple silicon dies on top of each other. This is my understanding, but is there anything new to see?

This is a timing issue with the trading. ETFs stop trading at 4pm. And the index for the ETF is calculated at the future close time of 415pm. Eastern Time.

Sure, there's after market hours trading for ETFs but liquidity is probably a lot less after 4pm.

Nonetheless, the failure to calculate a live index after 4pm is probably close to irrelevant for the average investor here.

Just so people know who is posting this - Donald McNeil Jr was the chief voice at NYT focusing on covid. He was ousted earlier because of some remarks that he allegedly made to a school group a few years ago, but before that, the NYT was pushing for him to get a Pulitzer for his reporting on COVID. Him starting legitimize the lab-leak theory as possible is reflective of the people more generally taking the lab-leak hypothesis seriously.

That's never to legitimize violence, or score political points, but maybe to get us a bit closer to what sparked the pandemic.

"You can't threaten them because they have little to lose."

This also reminds me of how some drug companies are pricing gene therapy drugs (like to restore sight, fix muscular dystrophy, etc). They have admitted that they weren't pricing the drug based on what it cost to develop but based on what that person's [function] is worth to them. If your pricing model is based on desperate people being willing to pay anything, then I don't think these executives have thought this through. Desperate people may be willing to pay anything, but when they have nothing to pay, then they are also willing to do anything.

I think this can be a similar situation in the "justice" system. If you have no faith in the system do to their track record of misconduct, mistakes, etc, then you have no incentive to believ in them or try the legitimate path.
Much of the cost increases you see in figures like those quoted for CAHSR are related to timelines.

First, projected infrastructure project costs in the United States are usually quoted (by agencies) in year of expenditure dollars, which means projected expenditures for each particular year are literally inflated. If you push a project back 15 years, you can easily see double-digit percentage increases in quoted total expenditures. I don't know the exact figure but AFAIU this is very much the case with CAHSR--a large fraction, and perhaps even a majority, of nominal cost increases is related to inflation adjustments as the timeline keeps getting pushed back and stretched. (Of course, that still leaves a large component that isn't.)

Secondly, pushing back timelines incurs all sorts of additional real costs. For example, you have to extend supply and labor contracts, which often means you end up getting less for your money because more people and equipment will end up sitting around idle for longer. You can also incur greater financing costs.

Also, I don't think any of the figures in that therichest.com link are inflation adjusted. AFAICT, they seem to just be tallying the year-of-expenditure or perhaps year-of-completion costs. This difference compounds inflation discrepancies even more. (There are other problems w/ those comparisons, too, such as that most of those airports were built far away from developed areas, but it's not worth going down that rabbit hole.)

Time is the the most critical component in all large construction projects, public or private. Time is money isn't just a catchphrase. If there are any hand-wavy, magical solutions to the cost problem that can be easily applied, one of the simplest and most obvious is to finish projects as quickly as possible. Don't let them linger and get stretched out.

Unfortunately, there are often political and regulatory pressures that push things in the wrong direction. If political blowback causes timelines to be stretched out, directly or indirectly, cost increases become a self-fulfilling prophecy. After learning about the accounting methods for how projected costs are quoted, and in particular digging into CAHSR costs, I vowed as a voting citizen to never oppose a project once it got off the ground, even if I initially opposed it.
There are non-periodical cicadas that have an annual lifecycle, but the ranges of the various broods of periodical cicadas do not overlap a whole lot. The Great Eastern Brood is the biggest of these and its range roughly corresponds to the most densely populated region of the country, so most people who experience periodical cicadas experience these ones.
