Of course it requires more than experienced personnel, but the person I was responding to made it sound like the Navy doesn't have people with the experience to run such a program which is what I was arguing against...the Navy has many personnel experienced with nuclear weapon system maintenance, operation, program management, etc. from which they can draw from...

Mods on existing ships has been done before...logistics/legal/security for boats with nuclear weapons are already well established and these converted ships would probably have to be either relocated to where the SSBNs reside or new facilities would be built that mirror the SSBN bases...in any case, I don't see it as being "impossible" to accomplish.
As someone who spends a lot of time helping answer questions about using React: what aspects of React and JSX do you consider to be a "high bar"? What concerns about React cause you to say it's not "beginner friendly" ?
I agree with all you said - I could have written it myself.

But I do suspect that, like myself, you are well-educated and probably from a stable home with parents that were good role models.

Someone whose home life was chaos probably wasn't lucky enough to been demonstrated those life skills.

It's sad, but I don't want to pay for people making totally avoidable bad decisions. I don't know the solution but whatever we can do to avoid kids being raised in chaotic home situations would help in the future.
Do people really sleep under blankets on nights >20C? I don't, despite the 'history of bedding'.

Give the many orders of magnitude of info these days being recorded and stored historians will have way to much junk to deal with.

Besides which, why should people live in pain today for someones hobby in the future?

This law is specifically to help individuals.

Does anyone know of any resources to learning about compilers and building a small, simple compiler for beginners?

It's kinda shitty to imply that someone is lying or delusional because their lived experience doesn't match with yours. There's plenty of literature on how autistic people learn socialization and how it differs from neurotypicals.
To me, the most concerning thing is the level of government officials requesting delisting. Democracy requires transparency. If you've committed crimes, had financial judgements against you, or even been accused of sexual misconduct, I want to know about it.

Powerful or high network individuals or corporations requesting delisting should have a much higher bar.
To solve problems caused by sitting, learn to squat (2017)
It’s an interesting question, and could have imagined people sharing their beds with pets, but with livestock? Is funny.

I personally have sleeping problems in rooms that are too warm, and warm blankets don't help. It's not when going to bed but a few hours in - around REM time? I wake up panicking as if I'm suffocating. That's why I always sleep with the window open, also when it freezes on the winter. My SO is not so much a fan :).
Because surface ships have better communications with shore, and would be more likely to receive a message quickly if AEHF, MILSTAR, and TACAMO are all destroyed in a surprise attack. That's useful both for ordering a retaliatory launch, and detecting if the ship has been attacked/destroyed.

The Russians have also deployed a similar missile on surface ships, and the land based version is in violation of the INF treaty. There is a desire to show that we are willing to respond to an escalation, and to counter it without violating the treaty ourselves.
I don't get how these logging and sending commands to a car use cases benefit in any way from a blockchain as opposed to just having a central server handle it.

If anything, having Porsche be responsible for the security of that system is a benefit. Not to mention the reduced overhead.

I am very interested in seeing how my assumptions are proved wrong.
Temple Grandin gives me hope for severely autistic people. She's an amazing example of someone who has done well for herself despite very pronounced deficits and original diagnosis of non-verbal autism.

I'm not very hopeful that it will ever be fully "curable", though maybe I'll be proven wrong. If we could at least medically correct for the overstimulation and hypersensitivity aspects, it would be such a huge win. I strongly believe the most negative and impairing parts of autism stem from this part. The people who are "merely" socially awkward often hide these aspects or avoid situations that would trigger them (ex: I carry ear plugs on my keychain because street noise or crowds in restaurants can be overwhelming, and I don't do tech conferences any more for the same reason). The more severe amongst us unfortunately usually need more than muffled sound to feel in control.

That said, I do think there are ways of coping, tools, practices, that will make life for autistic people much better going forward. We need to keep researching those just as much a cure or pregnancy-time diagnosis. I hope things do get better for both you and your daughter.
I guess I'm one of those weirdos that doesn't. I get hot really easily, so unless the sheets are really light cotton, I roast. Oddly enough, though, I love heated mattress pads. I can crank it up to 10 and sleep without sheets just fine.

Something relevant: does anybody have suggestions for weighted blankets? My SO is into big, heavy comforters and other bed coverings (no idea what they're called) and she'd probably enjoy that.
What a wonderful answer. I love hearing "programming" as "craft", I can't articulate it yet but it's a combination of science/art/other trades.
In 's4vi0r’s defense, “FP” usually means ML-style FP, which does happen to be pretty biased towards creating stack-based FSMs since it has literal syntax for stacks (list literals), states (discriminated unions + tuples), and transitions (pattern matching).

I have just purchased my first home and I would like to make the most of it, but I have no idea where to start.

I'd like to setup maintenance schedules to make sure everything it looked after, and I love the idea of home-automation too.

Is anyone here in a, or been in similar situation and can share some advice?
I've never heard of such a thing and from a cursory search, this could probably be considered a hidden way to discriminate and be illegal.
As we’re seeing here, we don’t always. Taking the premise as true though, maybe it’s modesty, or a way to normalize temperature fluctuations? From my experience in the Phillipines though, I’m with the rest here who are denying the premise of the article.

That's a pretty "out there share". Appreciate it. If you're ever in a position looking for a DFW (DALLAS/ Forth Worth) position, let me know).
I think the author's primary point was that the work done by mraleph required _deep_ knowledge of the V8 JIT internals and low-level profiling to get those "3x speedup" results, plus the algorithmic improvements. Meanwhile, the original Rust implementation got the same "3x" results without having to do deep analysis of how the compiler was behaving. It also seems (based on the commentary) that the way JS/JIT engines treat WASM bytecode is likely to require fewer special-cases or heuristics than plain JS.

Sure, the Rust compiler and the LLVM infrastructure are doing a lot of complicated work internally... but the end users of the compiler aren't having to spend time digging through the guts of it to guess what kind of magic sequences are needed to get fairly good performance.
That exact notion is covered here:

The 80/20 of White Hat Link Building: 5 Simple Tactics That Work – TheNextScoop
I'm absolutely a believer that some form of this app will be the future of programming, probably with a touch of Eve, some AI, etc.

I'm also looking at this problem, but coming to it from a different angle. I'm not a designer, and I'm not at home in Sketch. I'm looking at developers that can take a very well designed and coded HTML page, where the designer themselves has built the interaction design in whatever they feel comfortable in. I'm looking at a model of taking those pages and adapting them in a similar way, into React - or other framework - driven applications.

This comes later. I'm starting with a simple template language that can capture a component-driven design in quick to iterate, programming-in-the-large style. The compiler builds both a backend app which renders HTML that's ready to be infused with reactive goodness without an unsightly flash of re-rendered content.

We’re still paying for rich people to go to college. Why?
They're equally irrelevant, though. Poverty is when you don't have enough money. It's not a state of mind.

I thought some more about part of your earlier post:

> If you are really feeling hopeless you don't turn to HN for news on the latest programming frameworks.

This really doesn't make sense. I've known at least one desperately poor and depressed person who found escape and satisfaction in scavenging and programming discarded hardware. There's no reason people in poverty can't be hackers. Arguably they've got more motivation to hack than people who can just buy the latest widgets off-the-shelf.
Caffeine is known to make people sleepy as well. See the comments in this thread regarding "espresso naps". I can attest to their efficacy.

I wouldn’t call time complexity particularly complex math. Imagine a loop. It does something n times. Within that loop, you do something n times. For each outer looo through n,you do an inner loop through n. Trivially, this is n*n, or n^2, also known as quadratic time. If you nest another loop, it becomes n^3, or cubic time.

Anyway, there might be some confusion of terms, perhaps. Exponential time in the algorithmic complexity sense is any algorithm that takes 2^n operations to complete. If you’re talking about the number of iterations after you loop through n things n times, then that increase itself would not be exponential. But that delta in iterations is unrelated to exponential and polynomial time complexity.
“Column Tetris” – Calculating and Saving Space in PostgreSQL
As an embedded developer, I would agree that there is this sentiment that arduino is somehow inferior, bigger code sizes, worse code quality, training wheels, etc.

However, I've recently used a couple different Teensy boards in some personal projects, which are a line of 3 or 4 different freescale kinetis cortex M0-M4 parts that have their own plugin for the arduino IDE. I've been very impressed with the breadth of libraries, and how well it all works and integrates between different boards. The code is well written, and looks like it could easily be dropped into arm-gcc. Maybe Teensy is the exception, but there are some high quality Arduino codebases out there.

Not being able to use in circuit debug tools is a huge pain, however.

If it's too hot, I use a sheet. I think the explanation is pretty simple: crawly things that may come and bite us.
duvet cover?
Just like the secretary of state before her and the secretary of state before her and pretty much the entire current administration. Was it stupid? Yes. Should she be locked up? Only if you lock up everybody else.

The whole thing was a nothingburger trumped up because she, like Obama, was too scandal-free; and the press needed something to talk about to keep stories "balanced" when her opponent had a new scandal every day.
"here are also guarantees about when objects you allocate on the heap are freed; there is no garbage collection.
This is in contrast to JavaScript where objects are always allocated on the heap, and are garbage collected."

Surely you realize that this, and what the author wrote, are basically the same ever rehashed GC vs non-GC language discussion. Performance characteristics of each is not anywhere near as simple as any of these things claim, so i'm going to leave this alone.

"EDIT: If you want to learn more about memory management in Rust, see https://doc.rust-lang.org/book/first-edition/the-stack-and-t...

Again, i see no guarantees here.

I see it saying things like "This program has one variable binding, x. This memory needs to be allocated from somewhere. Rust ‘stack allocates’ by default, which means that basic values ‘go on the stack’."

Can someone point me to an actual language level guarantee in a spec? I looked, and i don't see it.

I can't see anything that makes it non-conformant to build a rust compiler that dynamically allocates and places all of these on the heap, and is very non-constant time for local variable allocation.

But again, i didn't spend more than a few minutes browsing, so i may have missed it (For example, https://doc.rust-lang.org/reference/memory-allocation-and-lifetime.html says nothing here, the requirements i can find in this entire chapter can easily be met by using dynamic allocation. There are not guarantees on space or time usage that would require a real stack :P).

In fact, the vast majority of requirements here look like they could be met by a garbage collected heap/stack. It would be horribly inefficient, but ...

I'm totally willing to believe nobody has written down a good enough spec yet, just saying i don't see it ATM :)

I want to strongly differentiate between what "one implementation of rust does" and what "the language guarantees". Because if you are going to claim it's rust that makes the guarantee, as the author did, you should be able to back the claim up.
Weighted blankets sound interesting, I'm also interested. Personally, I love sleeping under heavy blankets, but my room has to be ~55 F in order for it to work, otherwise I'll roast and wake up super dehydrated.
A thin sheet sometimes, yes. Mostly for comfort though, as I can go without.

This response unintentionally demonstrates what I think is a huge part of this puzzle: that government is the default "fixer" of this problem. That's an easy assumption to make, because it removes all personal responsibility while assuaging one's conscience. The Bystander effect in full force. What if we instead start assuming it is -our- responsibility to help the helpless?

Many comments in this thread mention the disparity between the Haves and Have-nots in San Francisco. Imagine the impact if all those Haves decided to use their own time and money to aid the homeless/hungry/needy/destitute? Instead, we fall back to blaming the other side's politicians and policies and we hope that someday Big Brother will take care of everything.
Yes, all of these are happening, and they're going to get worse and affect more people.

This list isn't taken out of context. It's from a detailed report outlining causes and effects, followed by policy recommendations and methods for governments to address each risk as well as mitigate climate change to reduce those risks. (It's also not out of context because I posted it in a comment thread about the effects of climate change [context])

Indeed, this is an excellent thing to consider when you are using immutable databases. GDPR is another such requirement that people are now having to struggle with. Essentially, you need to be able to rewrite the DB with the new information. For merkle chains that are in the public record (like Google's scheme to to publish certificate requests so that CA shenanigans are obvious to anyone that looks -- the name of which escapes me at the moment), it's not going to be reasonable. It's not so much the merkle chain, but the fact that the data is already distributed. Getting everybody to resign the chain would be pretty hard, but getting them all to delete the data is unreasonable... "Pretty please. We got asked by a judge, you know!"

So essentially, you need to make sure you don't put that kind of information in that kind of DB.

(P.S. It's a bit of a shame that you're getting down voted for such a good question, but I suggest you substitute "merkle chain" for "blockchain" when you want to ask technical questions of this sort.)
Not really understanding the downvotes here. I'm a potential Apple afficiciando, but at the Moto G4 pricepoint. Does that make me fodder of some sort?
I need something covering me. I’m sure it’s a culture/childhood thing to an extent, but I can’t sleep without a layer. It’s another reason why I always wear shorts and a t-shirt to bed too (plus I can’t stand the idea of making my sheets filthy even more quickly by wearing less).
This is awesome! Keep up the great work.
None.

Because in the end humans are the weakest link in any system, computerized or otherwise. I don't mean that in a flippant way or sarcastically. We're error prone and forgetful, emotional and spiteful. IMHO no bit of technology (hardware, software, law, or culture) is going to usurp our born-in biases and write a new chapter of history. In broad strokes we're already repeating history for the umpteenth time.

I've been on those toilets before at street-side filthy restrooms in hot & humid summer days, uncleaned vomit and splattered excrements of drunk people from the night before. It's the worst when you're feeling sick yourself from too much drink, and you have to squat for 30 minutes. You sweat like a pig and swim in a urine-covered floor; it's a full work-out session every time you go into a bathroom like that.
I don't think I could offer anything solid, no, beyond the general view that the litigious folks generally don't approach a platform before it's significantly large. (Most piracy on smaller mediums goes unharassed, for example, while The Pirate Bay and YouTube gets most of the attention.)
I’m the same. It doesn’t need to be heavy. During the summer it’s often simply a top sheet. But without it I find it really difficult to sleep.

How Akka Actors work
I think it's a very bad idea, and I suspect it's merely the amateur misapplication of a faddish tactic, escalation, to every time and purpose, by people carried away with ideology and politics and who have forgotten boundaries of reason and consequence.

That said, an existential problem the US Navy is facing (along with all branches of all militaries) is that precision, long-range missile technology is maturing and becoming widely available, making much of the Navy's massive capital investment, it's surface fleet, obsolete. How big a deal is it? Think of it this way (based only on reading foreign policy journals; I'm no expert in any sense):

* Long ago, naval battles were fought by sailors boarding each others' ships and fighting hand-to-hand.

* When cannon were developed and the tech matured, the enemy could sink you long before you got close enough to board them. The superior range of cannons made the boarding actions obsolete. Ships without cannon were merely floating coffins for their personnel. Eventually, cannon (guns) range increased to around a couple of dozen miles in battleships.

* The cannon dominated the seas for generations, but were quickly made obsolete by planes flying off the decks of large ships, with ranges of hundreds of miles. IIRC, at the Battle of Midway in WWII, the first battle to heavily involve aircraft carriers, the Japanese battleships never even saw an American ship much less have a chance to shoot a cannon at one. The battleships were merely floating coffins for their personnel. These days, U.S. aircraft carriers' planes have a range of around 500 miles without refueling.

* Precision missiles do or will have a range of thousands of miles. Those nuclear-powered aircraft carriers, the core of U.S. military power projection, naval power and strategy, each carrying maybe $15-20 billion in capital plus ~5,000 lives, will become nothing more than floating coffins. The Chinese military is investing heavily in this prospect; those aircraft carriers have long protected Taiwan, and the Chinese government is investing heavily in missile batteries to make sure the carriers never get within range of a battle in Taiwan. Precision long-range missiles introduce another game-changing problem: they are far cheaper to attack with than to defend against. Right now, there is no effective defense against a large salvo of precision missiles; even 1,000 high-end missiles might cost $1 billion - a great bargain for sinking an aircraft carrier, whose defenses might have to shoot down 99% or more in order to survive.

One counter-measure the US Navy is investing in is "distributed lethality": rather than concentrating investment and capability in one very attractive target (aircraft carriers), they want to put missiles and other capabilities on every ship, from destroyers to cargo ships, so the enemy can't take down your naval power with a few missiles. That's part of the reason, I would guess, for nuclear cruise missiles on Zumwalt destroyers.
>"The P-value is the smallest relevant value of α given your data (i.e., the smallest probability of making a Type I error and deciding there is an effect when there isn't one)."

Nope, the p-value calculation assumes there is no effect. How can it be the probability there is an effect?
