Diffraction gratings are composed of a series of ridges spaced very closely and regularly, and this physical shape is transferred to the chocolate through the molding process. Light bouncing off of the different ridges creates an interference pattern which varies for different wavelengths of light, creating a rainbow effect.

> That's 2-3 TIMES more than covid will kill

If people stay locked down and a vaccine or cure is developed. If not, we could be looking at 50-120 million dead (7.7 billion people * 70-80% who'll need to catch the disease to provide herd immunity * 1-2% fatality rate). And that's assuming that in none of those 5.4-6.1 billion people infected a mutation emerges that makes a SARS-CoV-3 that is different enough to render the antibodies ineffective.

There's just a wee bit of urgency here too.
> Why does the set include a rover and a grappling arm, if it will never reach the moon? What’s the satallite used for if it doesn’t have the delta-v to reach even low-earth orbit? LEGO, we need answers!

It's because the small hook like think on the nose is a anti-gravity hook, which "magically" fixes all problems ;)
I would assume it has something to do with information hierarchy. The more important elements are bigger, bolder, darker. If everything is this way there's less means to draw attention to important information.

EDIT: I can't tell actually if there's differences in color between the headings and body text in this case. If not... shrug
Google for a "reflective diffraction grating". If you shape the surface a certain way - grooves with a size near the visible wavelength, AFAI understand - you can get the reflected light to interfere with itself. The imperfections which vary the groove size then result in this rainbow effect.
Health officers are officers of the executive branch in nearly every typical jurisdiction I can think of. They are an extension of the governor/mayor/county executive, who can usually overrule/fire/replace/choose different decisions. And the elected officials are perfectly free to be accountable for the decisions of the executive.

I think the deeper issue here is the much-commented popular distrust or 2nd guessing of "experts". I guess a disease that has a long incubation time and highly variable susceptibility just brings out the worst in people's judgement capabilities.
Lego minifigs are mostly filled with air, while humans are mostly water. Water is heavier than air, so wouldn't that mean lower gravity?

Google Cloud Console felt slow to me too. And the user experience could sometimes be better too. For example: I set filters in a table of items, clicked many times to Next to paginate on the 10th page. Then I accidentally clicked on an item on the page, detail page shows. Clicking browser' Back button takes me back but the filter is cleared and I am on the page #1 again. State was not persisted so I could start filtering and paginating again. I am not 100% sure but I think it was the Quota listing. The old, document-style pages used to hold state!
In what way does assigning any blame help? Magically US citizens will be able to successfully sue China for lost wages? Magically there will be less deaths?
Depends on what you mean with 'lightmap' - if you mean the classic Quake 2-style slapping of colored textures on top of diffuse textures, sure, probably that wont be much of a sight in 10 years. However even nowadays (or years ago, really) most lightmaps contained more than that (e.g. at minimum you'd need directional information) and i doubt raytracing will get rid of the idea of precalculating lighting information per surface, especially as raytracing hardware becomes more programmable.
Very nice video and approach to the problem

Solution is simple. LEGOTimespace functions based on consensus of observers and rule of imagination.

Thus, they need big rockets to merely get out of sight. Once they are unobservable, they only need enough "fuel" to convince the two astronauts aboard they are doing fine.
> Anyways, I appreciate the insight on QE to offset deflation. Do you know of any interesting books on that topic I could check out?

Anything from Steve Keen, he has a good endogenous theory of money. He had interesting models back during the financial crisis which showed that austerity was deepening debt deflation, QE to banks was somewhat OK, and QE to consumers (helicopter money) turned out to be the best solution.
The end of progress in software engineering?
When we compare the performance of two equivalent programs in two different programming languages, we may still be able to test whether the one is faster than the other. That would be epistemically even sound. Still, difference in performance is not the main and certainly not the only reason why we have different programming languages.

We often consider the one programming language to be potentially better (at a particular task) than another, when the resulting program is more flexible, more maintainable, or just generally more readable.

In one way or another, a "better" programming language seeks to make the job easier for the programmer.

Let's compare two extremes of a "Hello world" program:

Expression 1 in Brainfuck:

++++++++[>++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.>---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.>++.

Expression 2 in Javascript:

console.log("Hello World");

I suspect that most people will find the Javascript version more readable than the one in brainfuck. Still, is there a way to objectively or even mechanically ascertain this proposition? Can we experimentally test (science) or computationally derive (mathematics) that expression 2 is more readable than expression 1? In absence of a mechanical answer to the question, the answer is merely a subjective matter.

Therefore, in absence of an objective and mechanically-verifiable metric for readability, the entire debate about the tools of the trade, i.e. programming languages, libraries, frameworks, and programs, is fundamentally unjustifiable and therefore flawed in an epistemic sense.

What's more, if we have no objective definition for the term "progress", we are not particularly likely to keep making any, especially now that the low-hanging fruit has been plucked already.

Therefore, progress in software engineering, and hence in technology in general, may sooner or later come to a screeching halt for epistemic reasons.
I can't justify $99 because the battery will eventually wear out and end up in the trash bin. Stop making throw away garbage!
Also people seem to forget that deaths are not the only problem. Getting out of the icu and surviving is not like a walk in the park where you get a little oxygen and continue with your life. Some % of people will never fully recover and live with health issues for the rest of their life.
> Not only are they better built

This could be true about some models some time ago. The unibody design is now common among other brands and is not a particularly good thing - the two components that wear out most on laptops is the battery and the keyboard, and traditionally on non-Apple laptops you could at least replace the former yourself.
Packer build using Ubuntu 20.04 server ISO
It's not, the download failed several times for me.

When it finally worked, I was disappointed to see that I couldn't get it to run on Win 10 (64-bit).

(It does appear to be a Windows executable, though)
The trouble is, this isn't even remotely close to feasible. In order to find a useful proportion of cases via testing, you need to test pretty much everybody with cold-like or disease-like symptoms or maybe even just pretty much everybody, and contact tracing only helps if you have some other way to find most of the active cases in order to trace their contacts. That's why experts in publications like the New York Times keep insisting that the US needs to test people on a scale orders of magnitude larger than any other country has managed, including the ones that are starting to reopen.

(Readers don't realize what a big ask this is because the articles carefully don't mention this - most people are left with the false impression that it's just doing what other countries have already managed, and that the only reason the US isn't doing this is because the leadership is incompetent or even deliberately covering up the number of cases.)
As a child of the $PAST in the UK, I lived in three overlapping Internet worlds. Acorn RISC OS 3, Mac OS 7.5 at home and increasing amounds of Windows 95/98.

The Acorn ecosystem was way ahead until it suddenly wasn't. But my first webppage in about 1996 was made on an Acorn machine and, as far as I recall, the text was antialiased back then.

Also The Futurological Congress as a film: how to take one of the funniest books I've ever read and turn it into one of the least funny movies. I think his sense of pessimism and the absurd is antithetical to modern filmmaking in some way.

Could you tell me about your method for this?
There's a patent for casting holograms on chocolate by the same process. (Holograms rely on the same constructive interference effect as diffraction gratings). You need enough sugar in the mix to produce a hard shiny surface to the chocolate.

You can also cut a record on chocolate, but you don't get more than a couple of plays before the needle wears away the grooves.
I feel the same haha

I have already built a middle page to preview before submitting, and will be deploying it in a few hours. Be sure to check back again tomorrow! :)
I also never understood why people like blurry fonts so much. To me, win2k fonts were much better than the ones we have today.

I guess it‘s because Apple did it.
Thanks for this description of the process.

I was mostly referring to the presses that separate the cocoa butter from the rest. It's not an easy process (example https://www.youtube.com/watch?v=HzcN3cbikzA ). Though as I pointed out, it's probably 19th/20th century technology.

They would not be atypical, because they are working during a pandemic, which is in itself a massive confounding variable. Even people who normally work from home are writing about being less productive than usual right now. This is not a good way to assess "working from home" vs "working in the office", any more than it would be to measure productivity of someone who was suddenly housebound with a broken leg.
Some would say signatures are used to verify I have agreed to something.

Others use signatures as a ceremony where the signing in the presence of witnesses (as per the article) is merely like the gavel coming down in court.

It signifies (ahem) the process is complete and it’s the witnesses that make it irrefutable, not the shape of my squiggle being inherently unique to me.

But the bank still wants my signature on file for security reasons. Can it be both — a biometric and a ceremonial action — or is the bank just engaging in security theatre?

If it’s a biometric, why are some people allowed to use X as their sign?

One nicely done detail is how the road names stay in place as you move the map. At least I really liked it.
Years ago, I read an article (perhaps in Scientific American?) about some scientists who had created holograms on the surface of chocolate. Their plans to commercialize it never materialized, and I haven't been able to find the article again.

I still remember one of the suggested uses of the hologram: to show an image of the filling.
Just to add some perspective - i'm using DDG exclusively because i'm really wary sending G any kind of traffic at all, since that will be tracked anyways.

Thats true. The point of the comment is that the set of people who just aren't cut our to work from home happily and productively is a lot smaller than the set of people who can't work happily and productively right now, no matter where they work.
A decent CEO would've explained the precautions to local government officials, persuaded them it was the right thing to do and then kicked in a donation of 500,000 masks or something. Instead, Musk is tweeting conspiracy theories and going on Joe Rogan. It's just incompetence. Even if the Tesla factory does have real and effective measures to reduce the risks, no one is going to trust Elon Musk.

My assumption always was- that they are not disorders. They are adaptions to circumstances, that thrive in these circumstances, through which human societys cycled regularly.

With the advent of modern farming, the ceasing of constant warfare and the finalization of the "expansion" to ever area of the planet, the usefullness of some of these neuro-archetypes just ceased to be, and they become first "troublesome" and then a illness.

That mentally unstable homeless person under the bridge, is rather better adapted to a country sliding into warfare with a neighbouring tribe or a hunter community who needs to move again, to catch up to animal herds moving onwards.

I don't think it's either minor nor nitpicking. It's not an alternative at all. If Google doesn't exist, this doesn't exist.

That said, I like the effort and it makes sense. It just shouldn't be called an alternative.
I had to reduce the batch-size to 512, because otherwise sort complained with batch-size too large. The timings are:

no improvement over sort without the batch-size...
The material difference is that this editor is an order of magnitude smaller than a browser. Sure, you can go "we have plenty of RAM/storage/battery these days", but consuming 10x more of every resource you can think of is quite the hint that you are not using the right tool for the right job, or that you do not employ the right person for the right job.

Yep, agree about the common codebase, that's why I'm trying to keep everything modular and thinking a lot about it. I describe this bit of my philosophy/design here [0].

Eh, cry me a river.

To put things in contrast: the Russian Empire, home of many great writers, such as Tolstoy, Dostoyevsky, and Checkhov just to name a few, had a literacy rate of about 24% overall; and at that, less than 13% of women were literate[1].

The truth is, reading has never really been the pastime of the masses, save, possibly, for a brief period in the 20th century.

Yes, they are still a thing, especially with David Fifield's variant, but even with simpler zip bombs. You would be amazed at what can crash an antivirus engine.

They made the same with local Czech eBay-like website https://www.aukro.cz/ . Previously it was a fast website. Transition to the webapp was painful, their filtering component was not working properly on mobile. It still takes several seconds until the initial white page switches to the rendered DOM. They lost many customers due to this painful transition. I think they fixed some of the problems (I know filtering component works ok now) but I basically stopped using it since that transition too.
Where I live politicians do make the decisions. They are only given advice from the health area. Epidemologists are usually way more educated than your average politician. I would even go as far as saying, that those highly educated people might have a better grasp of philosophical issues than politicians, who are mostly all talk. If I look at politicians at high level here in general, I have to doubt their ethics in general. At least epidemologists did not yet prove to be a lobby tool.

It still seems odd to me. While these projects are nice, if the functionality is not supported in the core system, it is rarely worth the additional trouble (imho). Situation is similar to gitless - git's cli interface sucks, but it is available on every dev machine.

There was a German TV show adapted from that: https://m.imdb.com/title/tt0978537/ (Ijon Tichy, Space Pilot)

It's pretty quirky. A mix of Lem and maybe old school Doctor Who. It operated on zero budget and thus had a few charming props.

If you understand German I highly recommend it. Sadly it's almost impossible to translate to other languages because of the made up dialect used in it, which is the basis for much of its comedy. But looking at clips on YouTube should give you some idea.

Ui designers have been replaced by algos generating nr of clicks, and programmers by JavaScript frameworks and libs.

Remember there was a time, a sweetspot, when browsing was something that would never tax any modern computer?

Nowadays, with my work issued laptop, many web pages (especially apps) load slow or are laggy. They even continue to load stuff while I scroll, which makes everything worse.

And we got used to that, just because each week a new tool, tracker or framework comes out that just needs to be out on the page post haste.

The stuff that web developers get away with through the ages would have gotten other devs fired.
