This seems like they have essentially codified wolfram alpha's many APIs and created the biggest, baddest standard library any language has ever seen, and slapped on some functions to access everything with. It seems like the wolfram language essentially sits on abstraction level max-1 which is pretty amazing.

I wonder how things break down when you don't want to do something that can be perfectly described in existing functions (ex. you need to perform some novel computation on an intermediate result of some function). Though I'm sure people much smarter than myself have made sure the code is modular enough to allow you to get your hands dirty (or they written the code such that if you have to get your hands dirty, you're doing it wrong)
I tend to agree. But maybe part of the problem is that few people have an understanding of what commercial fusion reactors will look or behave like. And people have even less of an estimate of the risk or cost inherent in their operation.

I certainly don't have a great idea. I'm assuming you won't be able to put a fusion reactor in a car or airplane. Will a fusion power plant be roughly the scale of a current fission plant? What will be the output? What are the risks? And how much do we trust these projections?
Well I only keep them there because I want to trade them.
Yeah... good point.
If legit, the soyoustart is a no brainer. This from a 100% colo guy. Building the hardware and owning the DC, you could do decent margins with their figures. I'm a bit skeptical myself, because of just how much you can charge as a premium on things like this. However, I will be checking it out further myself.
Blowing up 15 tons of TNT on the moon is visible from the earth - I would not have expected that. And now I wonder what a Tsar Bomba like bomb - 50,000,000+ tons of TNT equivalent - on the moon would look like.
Do you have any evidence to support your begging theory? I would guess that the homeless go where they can get shelter without being arrested. But I haven't checked the research.
Ah, right. Benchmark 1 is actually ~350ms on my machine. Thanks for the lesson in profiling asynchronous code. I revisited the React+_tree benchmark claims, too, and I think they are still spot on. If you're interested at all, I'd appreciate you taking the time to check my work there.

That's also my thought, but there may be more factors at play.

Any apartment building has significantly more regulations applying to it. Firewalls, lights in the stairwells (if multi-story), handicapped access, minimum sizes for doors and hallways, etc.. I don't know the whole story there.

The main thing from my point of view is that are these homes being built within walking distance of basic services (like a grocery store) and work opportunities?
Shit HN Says: the adjunct professor at CMU who's designing floating point hardware for processors is "totally stupid."

I'm guessing he intentionally underspecified for his audience, and if asked, could tell you in excruciating detail what 1% error means.

But skimming the patent [1], it seems that there's sometimes an error in a mathematical operation, measured as the computed value minus the expected value. The result doesn't seem surprising if you read how he defined addition in his hardware.

Average rate for iOS development is about $100 an hour.
In addition to some of the other good answers here, D is a good deal older than Rust and is, I believe, more stable and mature as a result. If you're looking for a production-ready C++ alternative now, rather than X months from now, it seems like D is probably a better choice than Rust.
As soon as the iOS version is out, everyone in this forum should advertise and really /push/ this to all their friends via FB, twitter, PM -- whatever.

Or just by plain asking them to install it, next time you bump into them in meatspace.

I see this question come up on here from time to time. I don't know much about homelessness in general, but I do have a brother who is a little mentally ill. Among other problems, he is incapable of keeping a place to live habitable. He utterly ruins a place over 2-3 years, gets evicted, and finds someone else who will rent to him (which is hard, he is blacklisted).

Something in him just won't train his dog, won't put food away, won't not get just angry enough to break things. Yet he appears like a reasonable person on the street. He spends most of his time at home too, so his life is pretty miserable surrounded by these miserable conditions.

We've tried hundreds of things to help him over the years, since I was a pre-teen, and it seems so intractable to help even just him, even with what should be enough money to support one person. It's hard to imagine how to solve the problem of all the world's homeless.
Why is printing “B” dramatically slower than printing “#”?
The mental cost to review hundreds of lines of code to work out the implications of every change before you can see any results is a problem - it breaks the creative flow, it prevents experimentation.

Type errors don't require such a mental cost. Once you learn how to actually read the error messages it becomes almost brain-dead simple. Compile, jump to the error message (hopefully your editor can help here), fix, recompile.

it breaks the creative flow, it prevents experimentation.

I disagree. What prevents experimentation is the fear of the unknown regression. Strong types give you the reassurance you need to boldly refactor without worrying that you'll miss something.
So MtGox internal documents say "The reality is that MtGox can go bankrupt at any moment, and certainly deserves to as a company"? That sounds...unlikely.
I worked on Mathematica for 2 years, and really the biggest downside is how its an incredibly powerful tool that fails in many practical applications. It failed to power the backend of a search engine (Wolfram Alpha), and based on my latest version of Mathematica, the dynamic computing features, visualization, and JIT compilation features still have a long way to go. It's an incredible and fascinating tool when you're given these toy models to put into it, but I don't really see a Wolfram Language revolution happening anytime soon.

One aspect I think Mathematica will excel in is code generation. Using symbolic constructs in a very high level language to generate constructs of a low-level language is much easier to do in Mathematica than basically any other language.

On a side note - Linus Torvalds thought naming his operating system "Linux" was too arrogant. I think it's pretty bad marketing to name your programming language after yourself, but then again, the same social conventions that apply to us regular human beings certainly don't apply to Stephen Wolfram.
Having lived in several row-homes, those air-gaps have several benefits. They act as firebreaks for pests and rot, actual fires, and significantly reduce cross-unit noise. They also allow (perhaps minimal) natural light in through the side.
If you believe in evolution and natural selection, then your functionality is just fast and accurate enough to keep you from dying before mating. That's as good as the optimization gets, except by random accident.
It won't lead to an erosion of anything. There's already the usual suspects: China, Russia, Cuba, NK, and Venezuela. There is no everyone else except these usual suspects. Will it be eroded in British Commonwealth? Nope. Any European country except possibly Germany? Nope. South America except Venezuela and Brazil's rhetoric? Nope. Africa? Nope.
How does an unmaintained phpBB install count as a 'spam history'? By that metric probably half the amateur websites on the internet are 'spam websites' because they have a forum that isn't actively maintained. I run across spambot-afflicted forums on a regular basis.
That's a massive amount of cash. And... the fact that there is a "leak from cold storage to the hot wallets" leads me to one conclusion:

It could have been noticed WAY before, if anyone had looked at the "amount that SHOULD be in the hotwallet" and the "amount that IS in the hotwallet" before re-filling it. That alone would have shown that there is/was theft or BTC loss.

Seriously, did MtGox run an exchange with virtually no bookkeeping?!
Apparently the risk is that someone would use it to create a dirty bomb. It's not dangerous unless ingested or inhaled, and it's not apparently easy to use as any kind of nuclear fuel. I guess this is kinda reasonable.
Small warning: CNAME at apex is commonly used for pointing traffic to a CDN or load balancing kind of service. These services tend to use DNS for part of their traffic orchestration (e.g. different DNS response based on user region) which gets less than optimal or even plain wrong results if your DNS server software resolves the CNAME instead of the end-user.

If they weren't using DNS as part of their strategy they could've given you a simple IP instead of a CNAME, saving your clients some lookup time.
You could save nearly 40% building costs by having 10 adjacent units versus ten free-standing structures nearby. That money could go into more solar or to build more units.

You go from 40 exterior walls (10 units x 4 walls) to 4 exterior walls at about 60% of the area. I can't tackle the math mentally to figure out how the roofing situation changes, but I imagine it is drastically cheaper as well. The roof would be two very long sides instead of 20 small sides.

The more I think about it, the more I am coming around on the "dignity" argument and I think having a space that is completely "yours," including a porch, some steps, and some garden area, will increase the amount of ownership felt. Want pink flamingos? You've got a hundred square feet of lawn that's yours.
Lots of stereotypes, but I have faith it'll be decent since its Mike Judge.
What's REALLY awkward? Google stole the BLINK name from a startup having used the name for more than a year. It's all a smokescreen. bit.ly/10gkQfn | The same goes for Microsoft BLINK. bit.ly/19k2snj | Can you say, "Deliberate trademark infringement to cause consumer confusion in a hasty attempt to prevent a potential competitors dominate market share?"
I'm curious, how exactly are the partner silos structured? Are the silos grouped by partner expertise, and startups rotate across silos based on what they want to talk about? Or does each individual silo have a set of partners whose combined expertise cover everything, and startups are assigned to a silo? From 26:30 in the video or so.
I agree with you about SSL, client-side hashing seems like a solution for a very mature website with clientèle who strongly value their privacy. Something like LavaBit comes to mind (RIP). But "useless" is too strong a word. It is really trivial to use stolen credentials on other services, and effective to boot. But by hashing on the client side in addition to the server, you "double" the amount of effort required to perform the attack.
But then it gets into the water supply and is bombaring your cells from nanometers away . . .
> Can it play Flappy Bird? Power the next cool startup? Give me an answer to a question I might have today?

Although it is possible to make games in Mathematica, it is a painful process.

At the Wolfram Technology Conference two years ago, I met some startup founders who were using Mathematica for some big data projects. It works great for people as a tool to use in the background for visualization and data analysis, but it's definitely not at the stage where a startup thinks "I'm going to deploy Mathematica to the cloud" or "let's build our interface with Mathematica" the same way they think about Ruby on Rails or JavaScript.
I guess it submerged, so it will hopefully reemerge.

I remember when this was first announced and tech blogs were making it seem like it'd be the next big thing, a universal inbox. Just goes to show you that even huge successes like Facebook often have trouble launching, and releasing new features. (See also the Facebook Poke application)
I'm also impressed by the efficiency of their UI. Most parts suppliers should take a lesson from them.

Maybe their policies have changed since 2003, because do they claim to ship outside the US.
www.domain.com and domain.com should not just silently duplicate the same content. If you want one to be "canonical", then the other should respond 301 Moved Permanently with the correct address. Duplicate content across domains is a mess for SEO.

> We at Facebook have a long history of trying stock tools and see them failing at our scale.

I can understand that, having experienced the same before.

I just re-read my message and I regret the way it comes off -- my intention in writing it wasn't to be critical of you, but to explore the issue of how inconvenient parser tools are perceived as being, and try to analyze why that is.

"Insanity" was meant to refer to the overall situation, and not you personally! I might re-word this a bit.

I still think that we ought to be in a position where the tool is so easy and so valuable that it is a no-brainer. And I think this largely indicates that there is a long way for the tools to improve.

meteor.js is really cool, but it is not ready for production, so it depends on how important your app is. Scaling it beyond a single server is actually not that simple.

Another factor to look at is how extensive the realtime functionality will be. If you just want to make a realtime dashboard for your app, using ajax with a partial to redraw a div every second (or do nothing if the ajax returns no change) is really simple compared to having to add the complexity of another service in a different language (remember that node.js will run on a different port and as a separate process from rails).

If your app is highly dependent on realtime, and you're not planning on launching to a wide audience in 6 months, sure, rewrite in meteor.

I really do not understand how it is possible to run a system size of MtGox without some kind of reconciliation.

You have a written record of how many bitcoins came in, were traded, and went out. Let's say you could not detect if transaction was successful or not, you still should have been able to detect that you are missing some bitcoins relatively quickly.
This reads like a tabloid. It may or may not be true, but this writing style is very panic-inducing. I don't recommend people take any[1] kind of action based on info received in this manner.

1. I say this, but if this makes more people panic sell and drive down coinbase.com's price below $500, I'm going to take a certain action... Hint: “Be Fearful When Others Are Greedy and Greedy When Others Are Fearful” ---Warren Buffett, but don't go sending funds to MtGox!

EDIT: OOPS!!! Forgot about this possibility: Note! We've exceeded our normal buy limits for today. If you would still like to purchase you will receive the market price of bitcoin on Friday Feb 28, 2014 at 04:53PM PST after your funds have arrived. ---Coinbase.com
Roughly $400 million at the current BC price. I wonder what that's worth in legal terms.
Try option C first and see how that works out for you. Seems like the least amount of work.
Part of it could be that 10 tiny homes can be relocated a lot easier than a 10 unit building. These could possibly be "mass produced" in a large warehouse and transported to various places that can handle various numbers of them.
What i think here is that the author actually knows what is the truth but can't prove without putting the source in a horrible position. Therefore he's just passing the news.

It's is completely neglectable if mentioned documents actually exist or not, MtGox actions speak for themselves: Marketplace total lock, pulled from BT foundation, national currencies blocked. Come on people.

Worth mentioning that while i was fascinated by the bitcoin world, i never invested in it. So far, all the marketplaces i was interested in, just failed (bitcoin-24 and mtgox). Bitcoin might be cool, but current web technologies can't guarantee consistency.

1. Rails + SSE (server sent events) - http://tenderlovemaking.com/2012/07/30/is-it-live.html

2. Rails + Pusher

Those are the best solutions, at hand that would work well with Rails.

I wouldn't advise smashing a Rails app and a Meteor app together unless you have a solid case to do so (like migrating).

Rails, aside, I'm happy to here oplog has landed. 1.0 feels imminent, the tension is growing, even here in Toronto. Stop waiting sheeple, Meteor is great as is, and it's only getting better.
This gets proposed from time to time (was Buckminster Fuller's Dynaxion Home the first?), but I can never see how you'd move them without crating up all your possessions. And isn't that the worst aspect of moving home in a traditional manner...?
> Two, fission byproducts are both extremely radiologically hazardous and continually producing heat from decay over long periods of time.

It's probably worth pointing out that those two things are the inverse of each other. The elements that take the longest to decay are inherently the least radioactive, because that's what radioactivity is: The consequence of radioactive decay. Something with a half life of 24,000 years is barely radioactive at all. Something with a half life of 24 seconds will give you radiation poisoning very quickly if you encounter a lot of it but won't be anywhere to be found if you come back in an hour.

The waste problem is also largely a political rather than scientific problem. The commonly-cited 24,000 year half life is for Plutonium-239 ("weapons grade plutonium"), which can be mixed at the outset with Plutonium-240 to make it unsuitable for bombs and impossible to separate, and then used as reactor fuel to destroy it entirely.

The most radiologically dangerous fission byproducts (largely Sr-90 and Cs-137) are the ones with ~30 year half lives, making them radioactive enough to cause significant damage and also long-lived enough to persist for several decades, but they also have significant market value in nuclear medicine or radioisotope thermoelectric generators or scientific research.

The massive political stupidity is in not removing the spent fuel from the reactor site and separating it into its constituent elements so that it can be put to productive use rather than sitting around waiting for disaster to strike. And the entire concept of burying it under a mountain for a million years is just ridiculous.
I guess it all depends on how "deeply" realtime your app needs to be.

For example, if you just want to add chat between users I think you'd be well-served by Firebase for the chat. If you want to roll-your-own, there are a million Node.js chat tutorials.

However, if you'll be making important changes to "real" data, as in anything you're persisting with ActiveRecord, b is your best bet.
What is with this Flappy Bird obsession? I stayed away from it.

Yeah I really like where I think it is, but it still has that "mad genius" feel to it, where one guy explains how awesome it is and you're left kind of empty-handed.

Want to see a lot more eyeballs on this and people playing with it. Hope Wolfram doesn't let "licensing fever" get in the way of the community understanding it fully.
Hustle: A persistent JavaScript queuing/messaging library
Off-topic: if an integral is an approximation of a physical process, then that process is an approximation of the integral. I.e. we could in principle have a "chip" running a miniature lab experiment (like water flowing) with sensors that would output "an approximate solution of the Navier-Stokes equations". Numerical analysts would then write new versions of their algorithms assuming "an efficient hardware solution of N-S". Has this concept ever been used anywhere? I guess quantum computing would qualify.
one guy, one time, managed to get his hands on enough smoke detectors to make himself glow in the dark.. yes, seems perfectly reasonable to freak out about.
You are the one being disingenuous. An ordinary person would be kicked out of the park before a single night had elapsed. The fact that the police eventually to some action doesn't mean they didn't also turn a blind eye for a long time.

Which ecosystems? And if you work in those as well then why are you bothering with an ecosystem that has "several orders of magnitude more crap"?

.01% is a small number - so you have 3,000-4,000 problems with the CLR and .NET framework.

Sorry to translate literally, but this kind of gross exaggeration and lack of data is what creates the "Microsoft sucks!!" attitude that is based on a 10-year old reality (at best).
They already had to port their apps or miss out on half the market. If say browser-based phones take 1/3 of the market, then an HTML/JS app will reach the whole, whereas iOS/Obj-C and Android/Java only reach 1/3 each.

What was it?
Utah is on its way to eradicating chronic homelessness[0]. Quoting [0] here:

>> In 2005, one state defied "political feasibility" and began handing out free apartments to the homeless. These were neither temporary accommodations or shelters for the night. They were not welfare-to-work, or only if you're married, or just-take-this-drug-test: just free apartments, no strings attached. Nine years later, they've reduced long-term homelessness by 74% and are on track to eradicate it completely by 2015.

It actually saves money, due to decreased costs of law enforcement and emergency medical services. Homelessness is a problem of distribution, not supply. Since the housing crisis at the end of last decade, homeless and home vacancy have both been well-above average.

> For any business, the process of collecting data, measuring performance, making changes, and reviewing if those changes were successful is really important.

This applies for any sort of goal/process/?, whether programmatic or personal.

Very cool story, I'm looking forward to additional features. We pull a lot of data about Docker from GitHub that could be more readily available. We'd be more than happy to discuss or beta any new features, if you're interested.
If the home is deliberately designed for this possibility, it might be easier than that. For instance, perhaps a grid of plugs to bolt your furniture into so that you only have to crate up looser items like books and vases? And you might be able to hide those under floorboard panels.
