I think the traditional difference between cobbles and a cobblestone something is the same distinction as pebbles vs a pebbledash something.

A pebble is of course a small rock. Pebbledash describes the decorative finish — which is made of pebbles and other material like cement or concrete — on some physical thing. You would say “my new house has pebbledash walls” or just by itself as a shorthand where it implies an unsaid word: “the pebbledash [finish] on this property gives it a delightfully vintage feel!”

So historically speaking, cobblestone describes a type of surface finish made of cobbles, and the two words have been quite separate.

Aerial is a fun one too. An antenna has components such as bolts and fixtures and junction boxes, but most prominently it will have a wire or other metal object that is thrust into the air: that is to to say a component that is aerial, or the aerial component.

Once I learned that distinction, saying “aerial” instead of the more precise “antenna” seems very quaint, like saying “wireless” for radio or “pianoforte” for piano. It’s not exactly the same as cobbles being used in cobblestone finishes, but they are interesting examples of nouns and adjectives merging into each other.
I've been meaning to ask in /r/theydidthemath if the quarantine is actually reducing violent crime, car accidents, pollution, other infectious diseases, STDs, etc. so that we may come out break even or even ahead compared to covid deaths. Just trying to find the silver lining here.

You’re expecting congress to be logical.

Mark Cuban actually had an equally interesting idea as yours - just let every business overdraw their account by some amount.

I like your idea better, but either way, there is zero possibility that congress could do it in a simple way - they just don’t have the DNA for simple.

Bad title and bad article.
I'm assuming you didn't bother reading my comment. No one here is discussing biological weapons except for you. I'm talking about a lab accident in a normal lab involving bat pee or bat blood. There were two accidental releases in a Beijing lab involving SARS-Cov-1 in 2004 (admitted by Chinese authorities), resulting in accidental human infections and death.

And it's unclear if that was at case here. It may well turn out not to have involved an lab. But it's also very much up in the air right now.

Next time, try reading before going off on a self-righteous rant.

Things I Wish I Knew Before I Started Coding
But developers, designers, devops, marketers and everyone in between need to justify their jobs so they need things to do.

Maybe this is a result of companies hiring way more full-time people than they need in the long-term instead of using short-term contracts to develop the initial product and now they need to keep all those people busy.
Yeah, mobile CPUs were always called SoC since at least flip phones era. Absurd some Apple fanboys think they made it mainstream or even invented it. Those are entirely false.

System on Chip are called System on Chip because they don’t expose I/O ports(like PORTA through PORTD on AVR) to the pins thus can’t interface RAM or ROM or other peripherals natively, but only over narrower buses through internal interface chips/logics.

In my rule of thumb, every surface mounted “CPU” between 80 to 200MHz across industries were called SoC from 2003 through 2010s.

Those CPUs/MPUs that do expose I/O directly to be interfaced to SDRAM, LCD or equivalents of North Bridge chip on PC were usually called either MPU or CPU, often MPU for they integrate some peripherals. Those were roughly 200MHz and above, including PowerPC for NAS or x86 for PC for which heat or footprint were not concerns.

Those under 80-120MHz were often called Microcontrollers(uC). They were also often self contained like SoC but didn’t count, also got a lot higher clocked recently but still don’t.

Intel and AMD refer to their systems as SoC since Apple started doing custom SoC, and that might give you an impression that it’s new and better. That’s not true.

SoC means CPU’s main I/O ports are not exposed to pins.
Wow, this is really interesting. Nice work!

Just a random example I found clicking around, an edit from the U.S. Department of State, removing a paragraph of criticism from the article "2003 invasion of Iraq". Looking at the history from Wikipedia, it was added back a few minutes later.

Schools and hospitals also suffer from Baumol's cost disease. As the production of computers, TVs, food, clothing, and other items gets more efficient, the relative cost of industries with low productivity growth skyrockets. Also including symphonies, theater companies, etc., and this leads to them becoming unaffordable in the presence of substitute goods, like movie tickets and recorded music.

> IMO that's pretty short-sighted. This line of reasoning is that the degree is valuable _because_ its exclusive, not because the degree is evidence of particular skills gained.

The dean didn't disagree that this was a major aspect of its value.

> If you simply took the exact same course structure and grading from a Harvard degree and put it online for thousands, the skills gained would be identical.

And which one would find jobs the easiest?

> It's unfortunate that this dean values those things over increased access to education.

The dean realizes that in a digital society, most things rapidly become winner take all. Their university has cachet, but not Harvard level cachet. They do not think that 99% of universities would survive everyone moving to online education.
> Unite the Right wasn't primarily about speech, it was about violence

This is easy to say with retrospect. How many other major protests in history would you have compromised had you known there would be violence?

Any embedded provocateur could easily kill any protest.

Any extremist portion of any political group, no matter how small, could kill the mainstream purpose of the wider legitimate group.

I'd much rather we strongly defend their right to protest in public spaces, regardless of ideology, and instead we react to any planned or actual violence (which is already illegal). Including targeting individuals who have that as part of their agenda. Not attacking the larger groups at the point of their freedom of assembly. Which is all ACLU ever protected them from when they defend their right to protest in one city park instead of one far away from downtown.

I'd love to see where Unite the Right people fought for the right to commit violence in court and where ACLU had any part of that...
SSB is great conceptually, but is plagued with bad design decisions, and with JS. I gave up on it, after trying it couple of times.

The Romans didn't have computers, so they didn't worry bout using only 3-digit years back then. And today, looking back, using fewer digits than available doesn't cause any problem. There's only an issue going forward, when more digits are needed, which the Long Now is trying to mitigate (8000 years early).

When you say something “saves money” do you think it’s reasonable to require such a statement attest that there is a net savings?

If I go on vacation and set my Nest to eco mode, am I saving money? Sure, certainly I may be saving $5 a day in home utilities cost on my $300/day vacation. But that is not to say that said vacation is actually saving me money.

It would be accurate to say that vacation may be costing me $295 net instead of $300 face value. But just reporting the savings would be misleading.

I think it's great that they were able to share the potatoes before they went to waste.

I have a nagging suspicion that not enough people are taking the threat of the looming food shortage seriously.

The borders have all but shutdown, preventing migrant workers from working on the farms. Farmers in turn have stopped putting crops in. Meanwhile the meat processing plants are being shutdwn due to the virus, resulting in a glut of livestock and below market prices for it, which might seem good for the consumer but what it realy means is the farmers wont be raising as many animals for the fall and next spring. On and on the food supply chain is spiraling down into recession.

If you think toilet paper was hard to buy and made people crazy, just wait till this fall when the meat is all gone.

Unfortunately I don't have the solution, worse yet I can see how it is all going to play out and theres nothing I can do about it.

Still, it is nice that the farmer shared the potatoes before they went to waste, too bad they couldn't have planted them all, we are going to need that food come winter.

Articles can't be all things. It's a very valid article about a very certain topic, and gives a fascinating insight into how enormous the machine of our "regular" world is.

I personally find it fascinating that for (almost) the first time in living memory we get to have a good long look at what happens when that machine stops. I hope we learn a lot from it.

Aside from even the fatalities, the math still is that 50% of LA is presently unemployed. While some articles are somehow gleeful in the face of this calamitous reality, there is no where near a net balance.

The Fed has spent at least $2 trillion dollars on this already. Probably closer to $6 trillion by the time we are done. It is an unimaginably large cost to shut things down relative to any possible benefit.
I know this comment might be voted down, but I cannot help it: in times of crisis, ideology is not the answer. Capitalism works great in stable conditions. But it doesn’t manage externalities very well. Hence the need for a strong public sector and safety net that can reel things back in line in times of crunch.

Functional programming can make advanced shaders -- particularly distance field stuff -- significantly simpler. I pass first-class functions around all over the place in this example, which compiles down to GLSL: https://github.com/daeken/DaeForth/blob/master/FragmentToy/t...

A good example there is `twist-func' which takes in a world-space position, a block that hands back a twist factor, and a block that receives the transformed position (in object space). Once you start doing things that way, you end up with ridiculously rapid development, which is the whole reason I created this family of languages; started as an experiment to take APL/K, Lisp, and Forth and smash them all together, and it ended up working out well enough that I've kept it going for 7 years now.
So just quickly glancing at Wikipedia [0] it looks like most of the major line items for the LGBTQ+ agenda have been part of US Federal law for about 5+ years.

The LGBTQ+ community are basically ordinary people from all walks of life, including prominent names like Tim Cook and Pete Buttigieg. The community has I believe explicit public support from culture generating machines like Hollywood and political entities like the Democrat party. These aren't exactly wilting lilies in terms of power and influence.

It isn't obvious that supporting their liberties should take precedence over supporting anyone else's.

Indeed. And what are net economic losses? I'm guessing that it's somewhere between 100 and 1000 times that.

Public means non-profit and wholly transparent, explicitly dedicated to the creation and expansion of a software commons. It infuriates me that people who work on important projects like numpy or Tor which are very widely used have trouble paying the bills and keeping a roof over their head.

I don't make it because I don't work in the software industry and don't have access to large social or financial capital networks. That sounds a bit like asking why someone who proposes a public policy idea doesn't just run for President.
It would be simpler to work out a canonical reduction for JSON. This should be reasonably easy since there are so few elements to it.

A simple proposal for actual security guys to rip to shreds:

Strings are represented as utf-8 blobs, and hashed.

Numbers should probably be represented using a proper decimal format and then hashed. If you're reading the JSON in and converting it to floats, you could get slight disagreement in some cases.

Arrays are a list of hashes, which itself is hashed.

For objects, convert the keys to utf-8 and append the value (which will always be the hashed representation) and then sort these entries bitwise. And then hash all that.

Or, better, it'd be great to have an order-independent hash function that's also secure. I doubt xoring all the pairs would be good enough. Update: a possible technique[1]

I'm not sure. If this was a lab accident(big if), it's possible that a whistleblower could succeed in defecting. I'm guessing Western intelligence agencies also are hard at work at this issue, using assets and technologies we probably aren't aware of.

Regardless, it shouldn't be our primary focus at this time. But sooner rather than later, we need to determine exactly how this happened so we can avoid it in the future. If it was a wet market, then by God China needs to shut them down permanently (wet markets are opening back up now, which is another reason I suspect it was a lab). If it was an accidental lab release, we must demand much higher safety standards, and make sure that's enforced.

This pandemic could have been so much worse. Next time, it could destroy modern civilization.
Both pandoc and shellcheck are written in Haskell, so the world's getting mileage out of it. Granted, the author of shellcheck has mentioned that he might not have chosen Haskell if he could do it over, but I think that was mostly about it being hard to get contributors (take that with a grain of salt; I'm too lazy to look it up).

In theory, anything that can have at least two distinct observable states can be used to store/transmit data. That is, after all, the whole principle which makes binary digital computing possible.

Wait, consumers pay the producers? As in, “you need to pay to download files”?

I think it was clear in advance of Unite the Right that many of the groups actively invited by the organizer were interested in violence. This wasn't embedded provocateurs or out-of-control extremists. Furthermore, Charlottesville didn't deny Unite the Right a permit - they just offered them a permit at a different location than what they wanted.

Obviously the organizer didn't go to court and say, "I would like the right to commit violence, can you please give me that right because free speech." But he did go to court and say "Me and my militia buddies who are hoping for a civil war and are bringing their guns would like to hold a rally at this crowded location where police can't keep things under control, and the city said that we can hold a rally at this less-crowded location instead, can we have our original location please?" and the ACLU defended that.

I think we're too far off-topic to argue about whether my view of Unite the Right is true or not - but I think I've set out a coherent position about principles (and, in particular, if my view is wrong on the facts, then I am in favor of the ACLU's support on principle.) I think you'll find that I am, in fact, opposed to most riots and do not believe there is an unalienable civil right to riot. I do believe in the right of people to protest even if there's a violent faction you can't do anything about. (And, in particular, I don't believe that information in retrospect about the violence of a given protest is relevant. I would still hold the same position if nobody had died or even been injured at Charlottesville, because of the information we knew beforehand. That is, my position rests on it the ACLU having been wrong at the time they filed the suit, not after the fact, which is a good part of why I don't think they've learned anything from it.)
I actually believe him that there were strict control and containment measures were in place in the Wuhan Institute of Virology, which runs the BL4 laboratory. No one is going to fool around carelessly with BL4 pathogens. That said, an accident still could have happened (they've happened in US BL4 labs, despite very strict controls).

More to the point, evidence points more towards a release from the Wuhan Center of Disease Control laboratory, which was also doing live bat research on infectious organisms, but under much less strict controls, not the Wuhan Institute of Virology. Significantly, the Wuhan CDC building is only blocks away from the seafood market.
Ask HN: Are There Any Virtual Gym / Online Workout Startups?
Are there any virtual gyms / online workout program startups working to replace traditional gyms?

My partner's gym is a franchise of a national chain that has had a lousy time trying to take their business online.

They're trying to offer a pretty low quality and poorly customized offering and want $160 a month for it.

Curious if anyone's already using or knows of a newer startup focused on replacing existing in-person gyms, their community type offerings and challenges.
We also don’t have therapies or a vaccine — despite, again, years of advance warning about bat-borne coronaviruses.

This doesn’t seem like a fair criticism. How do you create a vaccine for a disease you’ve never encountered? We have a hard enough time guessing the right flu strain to vaccinate against let alone a virus like Covid.

And people seem to ignore the flip side of this - spending money to prepare for something that never happens. I’ve seen plenty of people criticizing the government for buying tens of millions of doses of Tamiflu and Cipro that just expire unused.
Interesting read.

The Walther PP series was a good future focused “fashionista” choice for Bond in film.

But I do think for the Bond character from the book, as well as the reality of the 50’s-60’s period, a small revolver would haves suited for both close range discrete carry self-defence, as well as offensive assassination.

From a more gritty/realistic viewpoint, targeted killings in a number of places around the world in the period often relied on revolvers due to their simplicity and reliability.

Ammunition failure was more common then, revolvers allowed the user the ability to sequence thru a stoppage/misfire.

Close combat stoppage drills then for semi-automatic pistols were not nearly as refined as today.
