They are using sputtering that is a method that use a big spark to remove some Cooper atom from a surface and put the atoms in another surface. (You can use other metals instead of Cooper too.)

The deposited Cooper atoms are not in the standard environment that they is use to be, like in a big Cooper metal block. So they attach to the surface in a weird configuration.

In the new configuration, the elections don't have the usual distribution (like the electrons in the atoms of a metal Cooper bar). Anyway, the atoms of Cooper here don't have more or less electrons that usual, so they are still "metallic" with some definition.

In the new rearrangement, the electrons are more densely packed. If you use the (wrong) Borh atom model, some of them have an orbit that is closer to the center than usual. With the correct quantum model, the idea is that some of the inner orbitals are usually empty, but here one of the electrons that is usually in an outer orbital falls into this usually empty orbital.

(It's much more complicated, because the orbitals are not static and they are rearranged in each configuratio, and the orbitals are not a totally clear concept when you consider the quantum effect of correlation, but let's keep this simple.)

So the new configuration is more compact, because one electron that is usually in an outer orbital is now in a inner orbital.

The outer electron was easy to attack by other chemical substances. This gives Cooper some of it's usual properties. With the new configuration, it's more difficult to attack the electron, so the atoms have some (at least one) property that is similar to the properties of Gold.

In particular, this property is useful to bound some Carbon atoms and help them react, so they can produce alcohol from carbon (and water and energy?).

Trafficking or major dealing in drugs can get the death penalty. But small scale use is often little more than a "fine". One major exception is yaba. It's a sort of metamphetamine that's associated with unpredictable behavior.

A couple of decades ago the drug was gaining enormous popularity, was dirt cheap (going for pennies per pill), and contributing to a wide array of social ails and crime. At this point the prime minister of Thailand went 'Duterte' on dealers with purging of all drug dealing and corruption related elements that at times involved summary execution. It was a hugely successful campaign that sent the price of the drug skyrocketing and its consumption to negligible levels. It also helped gain him widespread popular support. I think this event is what really solidified Thailand's anti-drug image.
With respect, that amount to much of the same with different words.

I'd agree, although I don't think the author is being deliberately misleading, it's probably more an issue of public perception due to Hollywood and anecdotal conversations. DoD members swear to "support and defend the constitution of the United States, against all enemies, foreign and domestic". Sometimes that means brandishing a stick, sometimes that means swinging it, but we're pretty agnostic about the means to achieve that defense.

"We are dedicated to revolutionizing mobility with innovative products that give people the freedom to do what they love by enhancing their mobility. "

It's one thing when founders claim to be revolutionizing this or that when in fact some major changes are afoot. For example, Zuck can make some lofty claims in terms of 'connecting people'.

But when people make some random thing that's been around for a while, in some niche category and then hustle us with this 'revolutionizing mobility' rubbish ... it instantly hurts credibility so much I wonder why it is that it even works, how are most people not turned off by this kind of stuff immediately?

From that sentence forward, I assume this is about the credibility of a Ronco late-night infomercial something or other.

Edit: I should note the rest of the article seems highly authentic. Maybe dropping the 'we're changing the world' narrative would tighten up the messaging, that said, maybe that kind of stuff works on regular folks.

Yeah, typically users are mildly annoyed by electron applications because they either don't fit into the basic style of the OS or suck away RAM. They stay because of the service, something that is provided (the walled garden usually)

Which is why electron is so popular. I'm sure the whole "it's way easier to whip something together that kinda works" is correct in the short term. You whip something up and rely mostly on the hype and viral marketing to drive your app.
Assertions about the difficulty of implementing effective parallelism reflects assumptions about software architecture that are common but not universal. The tools most people reach for tend to be either multithreaded locking of some type or functional "everything is immutable" style, neither of which scale well on real hardware. Complex applications that do use large numbers of cores efficiently use software architecture originally developed on supercomputers but is equally suited to ordinary machines with many cores: fine-grained latency hiding. In practice, this means extremely cheap logical concurrency, like proper coroutines, combined with a latency-aware scheduler (the harder part). This may not be "parallelism" in some strict sense but it has the same effect in terms of utilization and is sometimes used on supercomputers to maximize throughput.

Programming languages often have some level of support for necessary primitives, such as goroutines, but then hide them behind an unsuitable scheduler. On the machines where latency-hiding was originally developed as an architecture (notably Tera's MTA), optimal scheduling was done by the hardware itself which had perfect visibility into relative latency with no overhead. Things are not that simple on x86/ARM. If you want to implement effective latency-hiding, you'll be implementing an equivalent scheduler in software, and often by inference because sometimes the only way to know the true latency of something is by doing it. I don't think it is that difficult but schedule design is not something most programmers know how to do well -- it is magic buried in operating systems and libraries. Nonetheless, you see more examples of this kind of software design for performance reasons.

There are very few real-world applications that are so serial that latency-hiding is not effective at using all available cores, particularly in the server realm where the workload is inherently concurrent. The original target application for latency-hiding architectures was scaling graph analytics, which are often not amenable to more classical embarrassing parallelism.

i was actually thinking about letting my 3yo go to kindergarten by himself as teaching him independence since it's like 100m walk, but there is one road to cross and most importantly he is too weak to open door on both buildings, will see if he will be stronger by age 5-6 :)

> If you think Android is a decent OS try removing Google from it.

Actually that was one of my favorite things about my Xperia XZ1 Compact: running LineageOS without Google services. The battery life was insane, like 10-12 hours of screen-on time. I simply did not have to think about charging the thing; I'd charge it every 2-3 days.

Having a device that I could readily bootloader unlock that also has official AOSP support complete with device trees direct from Sony was such a refreshing change for me after years of hacking together homemade device trees for various LG devices.

I regret trading that phone for an LG G7, with its mediocre battery life, heavily bloated, laggy software, and precarious glass build -- also cannot ever be bootloader unlocked, and even if it could you'd have to rely on some community approximation for the device trees, forfeiting fully-functional camera support.
Let's just clear up my stance here:

"I want to be able to create a fake identity online..." Fine. Great. Have at it! Privacy and anonymity, what marvels in this modern age!

"...in order to evade the law while I commit crimes, or escape the law after my past crimes." Ehhhhh...this is a rough bit folks. Listen, you want to pitch full on class war, us vs the government "there is no just man working for the injustice of tyranny" sort of shit, that's fine. It's just that's the sort of shit that gets the government involved MUCH faster. I just feel a bit of subtlety might be better in the earlier goings.

In contrast, this product is literally what the manufacturer is claiming to have invented.

I'm at wedding in 2017. The dance floor has opened up and the party begins. Then the "DJ" in charge of music disconnects her phone to take a call - boo, party over. But aha! I take my S8 from my pocket, plug the standard auxiliary cable from the sound system into the headphone jack and push play on a club banger mix. The party resumes. I am a hero. Now it's 2018 and I have a Pixel 3 with no headphone port. I will never be a spontaneous DJ hero ever again....and this makes me sad.
The vast majority of soldiers I know, whom have been blooded in war, do not wish military conflict to occur.

"War is politics by other means", paraphrasing von Clausewitz. Its fundamentally backing up one's political positions by force of arms, to impose upon one's adversary.

While there are some jingoistic people who relish conflict, they tend not to be the ones making decisions. This isn't always the case, but militaries know what happens when adventurism runs amok.

That is, wise generals would prefer (imperfect) political solutions to problems, as compared to imposition of will by force. But simultaneously, they know they may be called upon to impose that force.
A number of distinctions involved:

• Instead of trying to build a robot to do everything, it's still a largely manual process, using low-priced labor (think a trailer out in the boonies with a disabled retiree running the thing content to get paid by the piece, versus a young urbanite who won't stay in the job)

• Doesn't depend on convincing authors to take on a second distribution channel that could compete with their first. BN's business model is predicated on large book runs, so it was always an uphill battle to get their suppliers to get on board. Imagine iTunes could only sell 20% of the music on the market and now imagine you have a bookmaking robot taking up $20/sf floorspace with the same limitation.

• Books produced with the distributed process are indistinguishable from the mass-produced variety, making the choice to switch quite easy for customers, since they can't tell the difference (other than one is in stock and one isn't).

• An "Espresso" machine would be largely for printing titles the store wouldn't stock (there's a reason they don't stock them: they wouldn't sell that well if they did). My approach would be largely for printing titles the store can't keep in stock. BN isn't in the printing business and that's getting to be a larger Achilles heel for their business model.

The source is about 700k of C, so there are all kinds of algorithms for folding and space optimizing, but out of the box it would not work too well.

3D artists have some very particular ideas of what makes for good unwrapping. In general they dont want stretching, but there are a bunch of special cases where "the right kind" of stretching is a good thing. My algorithm tries to implement all these special cases. (that are over 20 different passes that each tries to solve a specific type of geometry).

For CNC its actually much simpler, since the rules of what is and isn't permissible are much simpler.

This is literally what Slack moved from years ago, because it was very problematic, let me tell you why since I'm the one who did it.

* Adding new APIs was a huge pain in the ass, you had to write all of this ugly bridge code in Objective C, and the APIs ended up being super unnatural on the JS side. As a result, desktop integration wasn't done much since it felt like a "Black Magic" type thing. Writing new APIs in Electron is Just JavaScript, so you can make something much more natural.

* We could literally do fuck-all for people running old versions of macOS - you can't upgrade Safari on old machines, you just Get What You Get.
