Many of your questions are discussed in detail in "The 8087 Primer" [1] but I'll give a quick summary. (I'm not defending their design decisions, just providing what I've read.)

> The 80-bit format has an explicit 1, unlike the normal IEEE float and double.

Apparently the explicit 1 made the hardware much simpler, and with 80 bits it doesn't cost you much to have an explicit 1.

(To explain for others: in the normal float format, the first bit of the mantissa is assumed to be a 1, so this bit is not explicitly stored. This gains you a "free" bit of precision. But then you needs special handling for zero and denormalized numbers because the first bit isn't a 1. The 8087 stores numbers internally using the 80 bit format for increased accuracy. The 80 bit format stores the first bit explicitly, whether it is a 0 or 1.)

> The chip has BCD support.

BCD was a big thing in the 1970s; look at all the effort in the 6502 for BCD support, for instance. My hypothesis is that cheap memory killed off the benefit of packing two digits in a byte.

> We got an 80-bit format, but no 16-bit or 128-bit format.

They did a lot of mathematical analysis to decide that 80 bits for the internal number format would result in accurate 64 bit results. Something about losing lots of bits of accuracy during exponentiation, so you want extra bits the size of the exponent.

> Don't we like powers of two?

Looking at old computers has shown me that word sizes that are powers of two are really just a custom, not a necessity. In the olden days, if your missile needed 19 bits of accuracy to hit its target, you'd build a computer with 19 bit words. And if your instruction set fit in 11 bits, you'd use 11 bit instructions. Using bytes and larger powers of two for words became popular after Stretch and the IBM 360, but other sizes work just fine.

Now it makes sense. Some vendors may not take a prepaid card if they can’t verify that the card matches an address with the card. I would assume this would especially be the case for online merchants shipping physical goods.

In that case, you may have to provide an address on a website.
Is there a formalized definition of this "rabbit hole" people have been abusing ever since The Matrix was in theatres? I feel like it was originally a metaphor but it's being used more and more literally to where I hear it almost daily.
I would like to draw attention to the following statement from the story by Katie Mousouris, linked to in the OP's article:

>The hotel employee ID card I was finally shown had the photo rubbed off. It was only shown after I had been screamed at & the door pounded on, which was after I had politely asked to verify their IDs by calling downstairs.

Was the ID badge even legit? Unless the latching lock was in place on the door, these people representing themselves as hotel security personnel should have been able to open the door with their own master keys, correct? Whey should they scream and beat at the door after being politely asked a perfectly reasonable question/request?

Consider that these were not legit security personnel, and that the hotel may have been working with some undisclosed entity to target select DEFCON attendees.

Edit: Seeing how the 4th amendment prevents the government from accessing a hotel room, why on earth wouldn't a state actor parter with a private entity to gain access?

I believe the CDC estimates the low-end of lives saved by guns in the USA each year to be 300,000. High end to be a few million.

When you look at the costs between US and European healthcare, the difference isn't in gov't regulation. In the US each private healthcare company creates it's on medical billing codes and private health providers each need to employ specialists to decipher the codes of each insurer. In europe, governments generally regulate costs (and indirectly provide unified medical billing codes), and a variety of public/private entities all use the same codes...

The "amount" of regulation is mostly a red herring. One needs the right regulation.
... a brand new, mainline kernel will run fglrx just fine. It's user space (specifically the x srever) that decided to break fglrx. So how is that the fault of the kernel's unstable API again?
I wrote something like this once, and had maybe 3-4 applications that I wanted to use with it. mplayer was one of them, and it broke with my straightforward and absolutely reasonable window manager. It did display only a quarter of the movies since it thought the video window was fullscreen but it was only a quarter of the screen. The reason was a bug in mplayer's source code. It did not expect to be resized once and only once and being mapped only afterwards.

Another story, I've been an icewm user for many years and I absolutely loved it. But at some point the bitrot was too much. Windows that didn't gain focus because of newer unimplemented client<->WM protocols, clients that crashed for hard to debug reasons, and so on. There are still some patches being developed for icewm that try to make it work with some newer clients. And there are workarounds on top of workarounds for fighting with Java clients, but at some point I decided it was too buggy and switched.

Writing a window manager could be such a nice project if wouldn't mean implementing terrible but necessary protocols, and fighting with all the bad X11 clients out there.
Oops. Guess the joke's on me now ROFL.
I thought it was interesting that there are also sea nomad children who are able to see clearly underwater:

Although that skill didn't evolve. It's just something kids can do with practice, and the ability is lost as we age and our lenses become less flexible.

And in the EU, going by financial reporting, that seems to have been the goal. I just haven't seen it mentioned that this means investors taking on more risk.
That is a really good idea. It might be worth developing a platform for that. Convincing companies to trust their code to a third party service (or to even bother) might be a pretty big uphill battle, though. Still tempting, though.
I'll admit to not being steeped in the terminology, so feel free to educate me.. but some quick Googling suggests nobody else has called Treble a "microkernel." There are hits about Fuchsia (a totally separate OS), and some Android forks on microkernels.

I'm guessing that the Treble modules expose the traditional /dev and /sys interfaces like before, and these new HALs talk to devices through those, right? Is that not still a runtime-linked monolith, with fairly-thin userspace services between the kernel and the framework?

The bulk of driver code logic (e.g. interfacing with a touchscreen controller) is probably still running in the kernel - show me if I'm wrong. I would think this would be how you define a microkernel. One exception may be the GPU -- those drivers are often very thin in the kernel because of GPL, with a fat userspace library that they can legally keep closed-source.
Why would we care about the answers to these questions other than for regulation?
Isn't special relativity a serious mathematical problem for Bohmian mechanics?
I wish we could use NFC on an Apple watch. It would have saved a lot of trouble. Unfortunately the read range of NFC is too short to work on a climbing wall. The climbers wrist will sometimes be up 12+ inches away from the closest point on the wall. This was the challenge that I ran into with our first prototype.

As for moat, I think we have some patentable IP (another potential large cost to file for that patent) and because our model hinges on a relationship with the climbing gym, the big guys would have to establish a salesforce to sell into these gyms, which I think for the size of the market would not be worth it for them. If we can solidify a decent market share it would probably be more likely that they'd try to buy us out rather than fighting for those relationships, but I'm not certain about that.
Can you please offer a fructose-free option? Or at least tell your customers which products contain added fructose?

That is indeed a big downside of adblocker plugins. You are giving a lot of permissions/trust to a third party. I assume uBlock Origin is safe, but in that I am trusting not only the author but also that the Firefox AddOns "store" is uncompromised. Those are things I probably could not verify on my own.
The thing is that 80% of the usefulness of learning is that it's learning practice. This is why you sit for so much crap in K-12 -- you're learning how to learn. This rings even more true for techies who are always chasing a moving target (nonono, object-oriented CORBA RPC, nono, it's REST, it's Kernel SVM, it's Convolutional Networks....). The effort is (almost) the whole points.

If you don't keep your learning organs stimulated they will literally wither and shrink.
> Passing legislation now is not the reason she is proposing this

Now, sure. After the midterms... Maybe a different story (at least in terms of getting it to President's desk), depending on how they turn out.

Sure, not all of it will survive the process, but if the only substantive restriction that accompanied the charter was the political spending rule, Democrats would love to put Trump in the position where he'd have to either sign or veto that.
Hi there, Hacker News.

I'm a creator and developer of Slides Framework. We released our new version and even got a #1 Site of the Day on ProductHunt yesterday: https://www.producthunt.com/posts/slides-4

The new version contains a lot of changes, that makes it even easier to create an impressive page for your landing page.

Let me know if you have any questions!

I don't know about the history of plastic surgery in the US, but in Germany apparently a lot of the plastic surgery for veterans was based on experience treating coal miners. Due to the frequent and horrific injuries, some coal mines had extremely good surgical teams and a lot of experience in reconstructive surgery.

But corporal punishment for urination, as rayiner was suggesting, without providing free public toilets... that's just cruel.

I don't think the problem is caused by vast numbers if underprivileged homeless people. It sounds like it's caused by irresponsible, indifferent young men. There doesn't appear to be a widespread problem of women urinating in the streets.

It's perfectly valid to conclude that the problem is a lack of punishment and shaming of the unwanted behavior.

FWIW, I did catch it - at first I thought it's a typo, and after a few seconds realized it was intentional. It is a fitting title though, if a bit... smart.
If you plan on targeting the college market, I would focus the pitch on parents rather than students.

For a student, the alternative is to go to McDonald's and spend $8, or to go to an on-campus cafeteria.

For a parent, the alternative is to take a whole day (or more) to visit their child and bring a home-cooked meal in the trunk of their car (or on the train/plane/etc). At that price point, $24 is a steal. And the price of a "proper" dinner kit is probably on par with gift baskets the universities sell full of junk food/cake/candy/flowers/fruit salad.
But it's "others" (no "'") in the link ;)
Maybe because the author expected sincere discussion of the problems they are facing, and got a storm of crap dumped on their head by people who spent all of 2 minutes on the issue but already know everything about it and are very judgmental about it. There is no shortage of those on the internet, and dealing with them is very annoying. Not everybody can tolerate such environment.

USA is fairly variant in its own chaos, no president gets more than 8 years, internet censorship by the state is looked down by all parties; people who oppose the wars it goes can complain without fearing for their lives; a big chunk of this behavior and similar ones is because the US is made from people of a lot of races including Asians and Asia-descendants.

On the other hand China just recently confirmed a "president for life", that's always a bad idea, remember the last "president for life" China had? Yeah... So despite U.S. being more likely to start wars its open to change from the inside; China is a solid big time bomb with little to no space for change and once they decide to enter a war it will likely be the last one.
If they target people like me that absolutely will not eat even trace amounts of fructose, they might get somewhere. Our options are quite limited - most restaurants are absolutely terrible about putting sugar in food.

It wasn't clear from the home page that $24 is for "one meal that serves 3-4 people".

If it doesn't greatly increase the price of packaging for your product, you may want to experiment with showing pictures of (and sending) food in single-serving packages (so instead of sending five-six packets, you'd send 15-24 of them).

Another option is to go with a "Home Chef" style pitch -- basically saying "here's a dinner date night for two in a box".
YMMV, but aside from anyone that started in the Google & Facebook area, huge swaths of the economy are still dominated by closed source software.

From personal experience, this covers: any kind of software-driven hardware, health care, tax, CAD, POS, finance, transportation, & retail.

They're changing. But I'd estimate most Top 500 companies are at 0-25% open source migration of core business processes.
My mistake it must have been Acxiom.
I'm not sure about all colleges but a lot have had the rug pulled from under them in public contributions. In the early 2000s credit was cheap so to extend the campus colleges took out loans and mortgages to pay for new dorms and classrooms. Sure if you were a big donor you could send a few million and get a building named after you. So the donors paid the one-time fee of getting it built and it was the students who were born the cost of heating, cooling, and maintaining the actual building from tuition.
> In the US each private healthcare company creates it's on medical billing codes

In the US all public and private insurers are required by law (HIPAA) to use a specified sst of standard billing transaction formats and code sets.

Well, at least if they do billing electronically, as virtually all of them do.

Don't get me wrong, mixed-use zoning is great, but people rarely live next to their jobs. It's difficult to get both people in a two income household to work close to each other; where people want to live vs. where their employer wants to locate is rarely the same, etc. Tokyo, for example, is very mixed-use and very polycentric, but has some famously bad commutes.

Unfortunately NY is set up as a centralized archipelago; existing transport infrastructure is pretty much saturated, and encouraging outlying areas to gain jobs is not workable because Manhattan is the only place accessible to every single part of the metro area within one or two seats on public transport.

It's hard to use the tax boost to add more mass transit, because you'd have to bond based on projected revenues, which is fickle at best. The only places that tie redevelopment and transit together successfully seem to be in Hong Kong and Japan, but in those places the mass transit operator either already owned the land being redeveloped, or got it for pennies on the dollar as a de facto public subsidy, which would be impossible in the US due to the Just Compensation clause of the Fifth Amendment.
These trends and actions aren't arbitrary. It's a reaction to the fact that the world is becoming increasingly "Winner take All". VCs, having enough information to recognize this fact, are now shoveling more and more money into fewer and fewer investments.

On the plus side, I hope that means we'll get more companies that are truely taking on Moon Shot problems and not just building another useless app we don't need.

The danger on the other side, is companies that use those large funds for rent seeking behaviors that hurt consumers in the long run.
Yes I guess I do read a bunch of non-work stuff, or stuff that may be work someday :P I did re-read Douglas Adams, and I guess I read The Grapes of Wrath, that's within the last decade... I'm sure I've read some New Yorker long pieces, and I guess I do watch a lot of film.
>I think you should consider your addressable market to be greater than Indian expats - I'm a Brit

I don't know. I'm not Indian either, and I was drawn to it in part because it wasn't advertised to westerners.
Boy do I wish I had those problems. I'm being pushed in the opposite direction, to focus more on the organizational valence of problems, instead of working in a more technical capacity. People are mostly boring and working with them is such a pain. Always needing to explain yourself and persuade them... blecchh. I have written probably a dozen documents, all in slightly different contexts, where I explain in detail the workings of a particular system, which fundamentally is very simple, operating on keys and values. It's not complicated, and explaining it over and over and over again sucks.
> This bill seems like it forces socialism/command economy on all companies valued greater than 1 billion dollars

That's an absolute caricature of what the bill does. It doesn't mandate what products or services companies can provide, how they charge for those services, what deals they make, etc. There's none of the fine-grained control that a real command economy would entail. All it does is change the operative definition of fiduciary duty to include people besides shareholders who are affected by a company's actions.

There are both moral and practical justifications for this. The moral justification is that it's unfair to give corporations every advantage given to real flesh-and-blood people, while also preserving their natural advantages - immortality, immunity to imprisonment for crimes, and most pertinently limitation of liability. The natural state of the market does not include limited liability. In order for the state to extend that favor to corporations (by extension to their principals and shareholders) there must be some compelling benefit to the people the state represents, otherwise it's not a deal but a steal. Historically, when corporations were first created, it was on the basis of a charter spelling out the nature of that benefit and holding them accountable for its realization (e.g. to build a road, bridge, or canal).

That brings us to the practical justification. The lack of such charters has empirically been very bad for the middle class, for the environment, for political stability, etc. In short, the grantors of these favors - the people behind the government that defines and enforces civil law - are not getting their money's worth. They're giving and not getting, even more so when the benefits can flow overseas while the costs stay here. Once government starts doing favors for corporations without expecting anything back, what you have is neither democracy nor capitalism but oligarchy. Since you made the mistake of mentioning the Soviet Union, all I need do is point to its successor state for an example. It's a bad deal, and it's bad policy. Enforceable limited charters are long overdue for a comeback.

P.S. I'm no millennial. I'm a very early GenX if you must know. What that means is that I've had time to study this stuff at more than a superficial level, so your well-poisoning is entirely off target.
It doesn't mean you stop learning with Markov Chains...it means you move on to the next more difficult topic.

Full Harvest raises $8.5M to help farms sell their deformed produce
> autoscaling saves money when your demand is really spikey

Indeed. I've found the spikiness ratio (if that coined term makes sense) to be 2x-10x for AWS in general, and I was wondering if you (or anyone else) had a sense of how much that increased for these more premium services.

> and even then you have to do a cost comparison.

I have rarely seen this done, and, when I've talked to people attempting it, the common complaint is that AWS doesn't make it easy.

> The fastest throughput that I am aware of with EBS is 500MB/sec without doing RAID

Yes, per volume. I was, perhaps, too terse in my footnote. I was referring to the maximum throughput per EC2 node. Considering 40Gb/s would be saturated by about 10 of these, that's not very much. Real hardware can handle quite a bit more than 10 such SSDs attached.

> Of course instance storage is faster (https://gist.github.com/ktheory/3c3616fca42a3716346b), but is that a thing people do for databases?

I would hope so, but probably not in general practice, as it would require too much specialized knowledge. The main problems are that it's ephemeral and very limited in quantity. The impact of the former is reduced by the latter, of course.
