Sure, you can claim that but it doesn't mean squat unless your underlying circuits correctly process operations (*,+,/etc) on the representation in a way that is faithful to your claim.

In the book he talks about a simple unum with values -inf, less than -2, -2, between -2 ... -1, -1, between -1 ... 0, 0, 0...1, 1, 1...2, 2, > 2, and inf, also intervals like 0...2, -2...0 etc 1...inf, emerge when you intentionally use less precision.

This is a mathematically closed system that represents all real numbers and is even useful!
Managing all my car settings requires a touchscreen -- should I really have two touch screens for this? No. One screen, one computer, but two processes that are isolated from each other.

Respectfully, I think your comparison is false. There are always new libs with awkward dependencies on platform X.
But what part of that is just hubris or real estate investment? They arguably have enough people to run their retail and AWS operations and to expand those businesses without expanding people. A large portion of their other projects are just sort of grasping at straws to see if there is some sort of business there.
Incandescent bulbs are usually 60W but can be 40W for a reading lamp or 100W to light up a whole room. Those haven't been sold in most countries for a while now due to their extreme inefficiency, but other bulb types are often compared to a similar incandescent bulb. For example a 14W fluorescent bulb might say "60W equivalent".

Watt-hours really are as simple as they sound. A 14W bulb that's on for an hour used 14 Watt-hours.
Heroku Status: Routing Issue
FWIW, I got the impression that they didn't truncate the table, but just forced an update to it's relfrozenxid to advance the freeze age and allow the database to restart. That means there's a risk that rows that were currently visible would suddenly vanish as the XID advanced and their xmin became "the future". Eventually record of those commits would vanish and presumably the rows would then get removed (though I'm not sure on that without checking the code).
Direct revenue comparison between Wal-mart and Amazon makes no sense. Amazon revenues are a lot more diversified than Walmart.

Portions like AWS, Digital and 3P/FBA service revenues will have much higher margins than first party retail revenues (which is the most like Wal-mart revenues, except the margins are completely different due to no having brick-and-mortar stores.). Additionally, Amazon is a lot more international than Wal-mart so comparison is even harder.

All of this completely ignore the growth rates of these two companies.
Rougly speaking It would be 1.414... + plus a bit that indicates the result is between two adjacent exact values. This bit would not be set if the result were exact.

It's not the same as dyadic interval math, it's kind of a hybrid.
Speaking as someone who has worked with Accenture people on a government contract, Accenture is the most hellish employer I have had any kind of near-direct experience with. Between the mandatory, unpaid social events, annual performance reports, monthly performance reports, weekly performance reports (which, due to scheduling, needed to be done before the month or week in question), the "career counsellor (who, according to those who worked for Accenture, was mind-bogglingly stupid), the Accenture manager (who made Dilbert's pointy-haired boss look competent and effective), and the assorted other inanities of government work, I wouldn't have lasted with them two months.

I won't work for IBM again because I've experienced their insanity, but I know people who were happy there; I wouldn't recommend Accenture to anyone, literally including Hitler.

> Engineers working on TCP decided that a 3-way exchange of messages (3-way handshake) could be used at the beginning of a connection. This is what is currently taught in all of the textbooks. However, in 1978 Richard Watson made a startling discovery: the message exchange was not what achieved the synchronization. It was explicitly bounding three timers. The messages are basically irrelevant to the problem.

You do realize you're making this comment at a time where every major Amazon metric is pointing up? I'm not disputing how you feel about Amazon but it seems pretty clear that you're the exception and not the rule. Amazon is currently firing on all cylinders and rather than making bad decisions over the years seems to be enjoying the benefit of making good decisions over the years.

It's sad that they mistook kilowatts for kilowatt-hours, but I think acre-foot is a good unit for measuring volumes of water. It helps communicate the scale of water use.

Briefly, in 1981, Apple led on revenue.[1] (XLS file of sales data.) The Commodore 64 and the Atari 400 were much cheaper machines than the Apple II. Then they were all crushed by the IBM PC and clones.

This is part of the generalized comprehension syntax. You can also do lazy generator comprehensions.

a = (i for i in range(10) if i % 2 == 0)
print(list(a))

You can omit the parenthesis, and use them in calls which expect an iterable.

b = max(i for i in range(0, 10) if i % 2 == 0)
print(b)
Are you describing CQRS? http://martinfowler.com/bliki/CQRS.html
In our case, we did netflix that we manually synced up and just do videochat on skype. Facetime doesn't work because it hijacks your sound, turns down all other audio sources and you can't turn it off. Silly apple.

The skype is nice because it puts a thumbnail of their face that stays hovered over the netflix even while it's in fullscreen.
Capital driven entities excel by maximizing revenue and minimizing cost. They perpetuate themselves and insulate their volatility by building vast warchests.

A public equivalence however, excels by maximizing utility. They perpetuate themselves by making sure the value they provide is near the cost they incur.

Take a gym for example. A private one wants to maximize membership dues but minimize actual facility use - that maximizes profit. A public one wants to be something that the community utilizes.

Generally speaking, in a public equivalence, the only party to enrich in the exchange is the customer base.

Now given this, a homogeneous state-run society sounds foolish ... but America's homogeneous capitalist society is equally foolhardy. We are sophisticated enough to analyze things and apply appropriate incentivized structures upon them instead of using the same one inappropriately in every use-case.
Interesting questions. I think part of what's going on is that people don't like being exposed to new, unknown threats. Even if this turned out not to be a very big deal in practice -- and I am not sure it won't -- it's still a new risk that's being assumed.

It was a challenge to heat the water quickly on 120V, but I think we have a good system. It not only provides instant hot water, but also allows you to adjust water temperature.
No, they received that round. Then another $50m later. This is yet another $400m+ round since then.
I would argue that unums are a "superior replacement" for doubles in many cases, though: in the case that you support unums that are "wide" enough, you can represent doubles exactly, plus you have additional values, plus some nice rules about when approximation error occurs/is propagated and not as many bits need to be stored or moved around on buses. It'll be a while before there's an implementation anywhere near as fast as existing FPUs, but Gustafson makes a good argument for his format. Personally, I'm more interested in the correctness benefits than the space/power/time savings - even if unums are never faster than 64-bit floats, they present an interesting way to do real-number arithmetic and my brief exposure to them leaves me much more confident that I could write numerical algorithms correctly than with doubles - I do numerical/statistical algorithms with doubles in my work, and it's really a pain to reason about things that the "uncertain" (open-inverval) values of the unum format would greatly simplify.

They're also an inferior replacement in the case that you want to take advantage of highly-optimized hardware, and that getting a correct answer doesn't really matter. I don't see unums replacing floats for, say, video game graphics. But for numerical computation, it seems like the only real flaw with unums compared to doubles is the nonexistence of a hardware implementation, and the existing popularity of doubles.
One note on Nvlink: To get that you will AFAIK have to buy a Power8 system. They would need a cooperation with Intel to get support for this on their architecture - and Intel so far likes to keep them on a slow bus.
I would be more than happy to a post about my writing process if that's what you are referring to.
The concept seems very similar to Rabbit: http://rabb.it
Stock distribution and stock rules are traditionally skewed towards the investors and upper management; the technical team traditionally gets short shrift and is subject to constraints and limitations which favor the other folks.
Stock grants and stock options are very different. Founders shares usually get treated very differently.

Going public has significant downsides and substantial on-going costs (for example, reporting), but it is one of the few ways value can be taken out of a company by shareholders. I wish there were another way.
You seem to be implying there was some sort of scientific consensus instead of populist smoke-blowing.

Not at all. We love our Toronto investors and are looking forward to launching there in the fall.
For any unum system there's an 'archtecture spec' that puts parameters on the maximum sizes of the exponent and mantissa. You can have values that consume less bits, the format contains a tag that says how many bits you are consuming for each part of your number, a lower size indicates for exact values that less size is needed; for uncertain values it means the uncertainty is higher.

You could pad your values to achieve constant time indexing.
Compelling writing. Well done, New Yorker.
It's not exactly the same, which is what I thought was interesting. My first example did use a generator expression inside the dict() constructor, but in that case you need to specify the key and value in a tuple or a list.

With the dictionary comprehension you can just separate the key and value with a colon, which is more natural. It might just be sugar on top of a generator expression but it is definitely a special case, syntactically speaking.

Why We Adopted Material Angular for Our SaaS Platform
$15 a month. That's the number I was looking for but couldn't find until after creating an account and trying to add a phone number. Then a popup came for my credit card number (which I don't have) and finally, in the confirmation button, was the price.

Edit: Oh, it's in the FAQ. I checked all other pages except that one (seemed logical to be under either home or features, or perhaps policies). My bad.

Edit2: Giving the price a second thought, is this a normal fee in the US? Our landline costs just over 4 euros and the cheapest mobile subscription I've been able to find is 3.50 a month.
Yes the IAB (Internet Advertising Bureau) and MRC (media ratings council) and 4A's (American Association of Advertising Agencies) all have various "standards" and certifications. There are similar groups in Europe and smaller orgs that focus on niche areas.

Unfortunately for the most part these groups all charge lots of money for a nice seal you can put on your site, without any real checking of a business. Some of the most offending and insecure networks are members of the IAB. [1] Not to mention this has no bearing on actual technical implementations. The MRC does audits of companies to certify them for measuring viewability but there can be 50% or more discrepancy[2] between vendors which ultimately makes the entire thing pointless. And buyers also don't care, they have their own "favorite" vendors they want to work with so they're not even interchangeable.

The adblock plus company in Germany (while I dont agree with their entire stance) has an "acceptable ads" standard that at least lays out something in terms of user experience. However they accept money for whitelisting which is why all those crummy clickbait widgets like outbrain/taboola still show up through the default ABP filters.

What I want to see is actual legal regulation that covers how a business deals with data/privacy and then some kind of technical certification led by a real tech-savvy company to vet ad networks and their implementations. However this industry is full of political motives and other shady dealings so it takes a herculean effort to do anything... Maybe with some consumer backing there might be changes given the wide usage of adblock today but (not) surprisingly most digital ad execs see it as some kind of plague rather than the direct consequences of industry actions. That's not a very cooperative attitude for enacting change.

The purpose of this male tears joke is not to create a debate, it is about feminist women knowing there are other feminist women out there. Men don't need that, they already know.

However, I do agree that in the context of a honest debate this really doesn't help, and I wouldn't use it there. But I know many people would, because in both sides so many people think debate is about winning, not conveying ideas.

Because

1. The publicizing of AMA's requires a lot of meta discussion and threads and one of the things that makes HN HN is frowning upon the promotion of meta discussion.

2. HN tries to be somewhat meritocratic, and AMA's are intrinsically tied to celebrity.

3. AMA's happen spontaneously from time to time on diverse topics, e.g. some project hits the front page and the author shows up in the discussion thread or a company hits the news and the founders show up to answer questions.

4. HN would turn into Reddit, which incidentally is the only acceptable meme on HN.

5. HN has a specific business purposes for YC. General internet interest does not appear to be among them.

6. Without coordination, the Ask HN page would be flooded with AMA's. e.g. https://news.ycombinator.com/item?id=5250690

In that case you're paying the cost of even more context switches. One to get into the UI thread and one to get out, in the case of a synchronous call. In a LockOSThread solution you don't need any context switches. You also save the memory cost of one goroutine (which is admittedly small).

Cars can have three separate networks for infotainment (radio, navigation, etc), body controls (seats, lighting, locks) and mission-critical stuff (steering, breaks, engine). Some of them actually do.

There is little genuine need to send commands from low-importance networks to high-importance networks. Yes, you would have to live without single uber-control touchscreen, but it's not really that big of a limitation: you simply need separate controls for low-importance and high-importance things.
Mobile trends: It's time for developers to think beyond the app
I downloaded the Makefile from the same site [1]. I changed CC to gcc (not sure if necessary) then just ran "make jarijyrki". The relevant build command makes it clear why your compile command fails.

I guess there was a limitation on the length on the compilation command too and the winner made use of it fully. You have to run it as "./jarijyrki < sheet1.info > myedits.info", sheet1.info is in the same site[2].

You can put a passphrase on the key and not worry about someone else getting it by stealing your phone, just remove it from authorized keys when you're back at a computer. Unless you're concerned about needing emergency server access while your phone got stolen and hasn't been replaced yet.

But at that point, we're probably also worried about the odds of getting run over by a bus and having amnesia that prevents you from using a password protected key, chance of getting struck by lightning, etc. ;)
One thing I've not seen addressed in this context: If someone wants to create mayhem on a highway, why would they not go low-tech / low effort? There's a number of mechanical and electrical attacks that I can think of just off the top of my head.

Analogy: is it worth the time making a pick-proof lock for the front door when someone can just break a window?

(I'm not saying we should let car manufacturers off the hook, just offering a perspective on the realism of the threat.)
What is an AMA?
This works very well in my experience. I wrote a "captcha/graylist-esque" rule for my asterisk server which intercepts unknown incoming calls with "because we don't recognize your phone number, please press one now -- or leave a message after the tone". Pressing one transfers the call to the ring group and whitelists the caller id.

For grins, _failing_ to press one results in my office speakerphone playing "sad-trombone-sound.wav" -- how I love to hear that sound.
He's a bit showy about the format. Wish he would just put out a technical paper.

Anyway, I guess his motivation might be "you can represent any real number (with finite bits, and therefore finite precision)". In the book, he presents an interesting case: little 4-bit versions of the Unum that can represent:

-inf, (-inf, -2), -2, (-2, -1), (-1, -1/2), -1/2, (-1/2, -0), -0, 0, (0, 1/2), 1/2, (1/2, 1), 1, (1, 2), 2, (2, inf), inf.

Putting together a pair of them, the book outlines simple interval arithmetic (where pairs of numbers can represent any interval between numbers on the line above, and single numbers can represent some of the closed intervals as above). The reason these are kind of neat is that using the standard Unum algorithms (without any fudging), you can get "correct" (albeit terribly imprecise) results for many real number computations. Questions like "is there a number satisfying a numerical predicate in some range?" or the value of a trigonmetric or exponential expression will come out "correct" (but you might get an answer like (-inf, inf)). If things work out as well as he claims (and demonstrates for some cases), then you can basically do the math to figure out how precise you want to be and choose an appropriate specialization of the format - or take advantage of the format's flexibility and do computations starting at a low precision and increasing precision until you are satisfied. In particular, it's kind of cool that you can do computations with little 8-bit intervals, and possibly circumvent doing more expensive computations (e.g. if you test if a property will hold anywhere in the Unum range and it won't hold anywhere, assuming you (and Gustafson) have done the math right, you can avoid doing more expensive checks with increased precision).

Anyway, point is, the presentations are kind of flashy and misleading - and you're right, you can't represent any real number (just finitely representable dyadic intervals)... but the format itself _does_ seem promising...
Yeah, that is valid. The vehicle shouldn't be visible on the net.

But that's the least useful way to protect us. Literally. If the vehicles remained visible they'd have to fix the bugs - this way they'll simply pretend they did.
