Except the degree of error introduced by techniques like "knockout" and "maxout" are a hyperparameter under user control as are the many possible implementations of stochastic gradient descent.

What's being suggested here seems equivalent to saying that because you love the crunchy fired top of creme brulee, why not go ahead and torch the whole thing?

As for contrastive divergence with Restricted Boltzmann Machines overcoming the vanishing gradient problem. That's true, but has anyone even tried doing this with 7-bit floating point and demonstrated it even works? I'm assuming recurrent neural networks relied on at least 32-bit point (correct me if I'm wrong). A reply to me flickered on here briefly indicating they haven't built a processor based on this yet which the author then deleted.

I think this would be a much more interesting architecture if it would just stop trying to reinvent floating point or "if it ain't broke, don't "fix" it."

I think their choice of GPL3 is a mistake; it's premised on the idea that people will only ever use one app to communicate and it'll be their app.

In reality that's never going to happen; people are always going to use multiple apps to communicate whether it's via photo sharing apps, games or something else.

We need a secure messaging infrastructure that transcends single apps - and that means it needs to be under a licence that can be integrated with both open source and closed source applications.

It's not just a case of integrating with consumer apps but also business apps. You want your secure messaging system to be able to connect to every CRM, help-desk, shopping etc. system and again that requires a more liberal licence than GPL3.

(Also it's not clear that you can legally distributed a GPL3 app on iOS)
Generational GC itself is not specific to java. But if you want to look at state-of-the-art collectors then you'll generally find them in JVMs.
Agreed. None of the options for accessing IPv4 only websites via IPv6 only hosts are great. If you are running an IPv4 only website or service this should hopefully worry you.
Entirely unrelated, but this headline made me notice that Chrome finally supports entering " in the find-in-page box and having it match so-called smart quotes.
Wow, that would be, unfortunate if true. Quite the heist though, and yet perhaps somewhat bittersweet. If it kills BitCoin what was gained by stealing all that BtC, unless of course killing BitCoin is the gain.

But given the transparency of the block chain, can we re-create the path of all the malleable transactions? Can we figure out where those coins went?
Singluar computing have built a chip based on this tech, and deployed in a military UAV. It enabled tracking of objects(which ws impossible before due to power constraints), at 6400x the performance/power of other best known methods.

http://www.defensetechbriefs.com/component/content/article/1...

http://proceedings.spiedigitallibrary.org/proceeding.aspx?ar...

From the paper:
"The hardware is designed to perform high dynamic range arithmetic with roughly 1% error per operation. Singular has
developed and studied varied algorithms for producing high quality results despite the approximate hardware. These
studies use a perfect simulation of the accelerator’s arithmetic. Tasks that have been explored include summing
thousands of numbers without accumulating error, k-nearest neighbor classification (KNN), foreground/background
separation using Gaussian mixture models, iterative reconstruction tomography, deblurring using the Richardson-Lucy
deconvolution algorithm, FFTs, radar processing, neural net learning, and other tasks. Most of these algorithms need
slight adaptations to prevent cumulative effects of the 1%
error, but with those adaptations all perform as desired."
One good resource for this kind of question is David MacKay's book "Sustainably Energy - Without the Hot Air" (free online: http://www.withouthotair.com/). He goes through each type of sustainable energy source and estimates how much power it can provide.

At least in the UK, the total potential for geothermal energy is quite small, much less than other sources such as wind and solar. But its a nice short-term supplement, we can construct them today.

Having working fusion would be an amazing thing. The raw materials (lithium and deuterium) are plentiful enough that they will basically never run out, it would provide energy forever.

One wonders if Glenn's persistence in reporting this issue is due to being targeted by NSA contractors like Palantir, regarding Palantir's work against US activists. A "Spotlight" as the email says: http://1.bp.blogspot.com/-2LJZSZknE-I/TVpg4sNeUHI/AAAAAAAAC6... Via street nigga's thread.
Thank you so much for sharing. It is a well-needed reminder that homelessness and lack of health care are a vicious cycle in the US, whereby medical bills cause bankruptcy and homelessness causes [an increased chance of] injury, disease and mental illness. The conversation about homelessness too often takes place among the privileges, whose primary concern is to put the homeless out of sight and feel less guilty. I'm ashamed that I don't spend all day every day in a state of moral outrage that I live in a society where the sick are sometimes not just denied care but actually bankrupted and put out on the street.
This seems super exciting. I'm not sure if you could build large-scale applications with it, but I cannot wait to play around with it.

Side note: The use of "I" and "My" really irks me. I imagine many, many people made this happen and contributed to these design goals. I guess this shouldn't take away from how cool this technology is, but it definitely leaves a bad taste in my mouth.
Civility should always be undertaken initially, not edited in.
I guess(??) I could have been clearer.

I understand what tomography is. I am curious how to interpret the three images and the differences. What does this page demonstrate to the reader? To me they look almost exactly the same. The one big difference is that the original has the the intersecting arrows. (I am also not really sure what the arrows are supposed to convey.)
I live on a boat, which has quite a lot of similarities to this. I have even less livingspace than these houses, but I've managed to fit everything I need and more into it. The marina I live in has a clubhouse which is the social hub, much like the common space that's talked about in the article.

Although the circumstances are very different (I live where I do entirely by choice, and don't suffer any of the other problems that I presume homeless people might) the physical living space is comparable, so I'll offer an opinion:

- Living in a small space is much less of a problem than people think. You quickly get used to it. You tend to be outside more though (which I think is a good thing)

- If you do live in a small space light is important. Small spaces without natural light don't work. I suspect that's one of the architectural reasons why the houses are seperate. The same goes for having a semi-private outdoor area.

- A common space is great because you meet other people. Again, the circumstances are very different but I've really enjoyed meeting people I can now call friends in our clubhouse.

- When living in a small space you have less belongings for obvious reasons. This is a good thing, which surprised me. Tyler Durden from Fight Club is spot on when he says "The things you own end up owning you"

This is a great project, and I hope it succeeds and spreads.

>I have to wonder what it looks like when a person suddenly becomes very rich without any explanation for it. Wouldn't at least some of these people have attracted a lot of attention?

There's no reason they had to actually spend the money. DPR had $85M in BtC yet shared a flat with unsuspecting room mates.
I agree. But that sad situation looks good from where I'm standing.
Well, it was written in assembly anyways, so you can decompile it, but there are many macros I used, so it might be hard to read (for example scrolling is done without a loop, just 1000 separate instructions). There's so much spaghetti in there. I'll probably release that once I have some time to clean up a bit!
Besides the pure cost savings of public services, I'd love to know about the second-order economics effects: the growth of the tax base, the founding of more small businesses and the increase in economic activity due to people (rightly or wrongly) feeling safer on the streets. One can imagine startups run by former homeless who have a unique perspective due to their experiences, or who have discovered inexpensive solutions to problems, or who simply would be the type to start a company if they hadn't hit some bad luck at some point.
I think it is absolutely illegal, it's just very hard to trace it. Oddly enough one of the plot points on the latest season of House of Cards is around foreign money being channeled illegally into Super PACs.
The big question left unanswered is: Do these houses have indoor plumbing, or is there a separate communal kitchen & bathroom?
The principle is sound but the analogy is flawed:

In this case the bucket's main contribution would be to collect the water, not carry it. If soup were indeed raining from the sky, a bowl or small cup would suffice.

MtGox would have to disclose all wallet addrs used for incoming deposits, hot and cold storage for that.

Given the holy fucking mess they're in already, they should provide full transparency - i.e. not only disclose the wallet addrs, but also the total amount of fiat cash they hold and which account ID holds how much BTC/fiat.

That would allow an independent entity to either resolve the clusterfuck (since obviously MtGox is unable to) or fairly wind down MtGox by evenly distributing the remaining BTC/fiat amounts, a small amount set aside for some lawyers to try to unfreeze the Dwolla funds.
Ask HN: What do you use for file backups?
I think you can have the best of both worlds with alternating doors. A big long structure where every other door is on the same side of the building, such that each person gets a small porch, small "yard" and their own door. This still limits the natural light.
I saw this technique proposed on a webmaster's forum many years ago. If google hasn't given some thought to detecting this type of manipulation, I'd be surprised. If they've actually figured out how to reliably detect and discount it, I'd be doubly surprised.
For example: realtime systems, rendering threads, embedded systems that require minimal runtimes. Smaller subroutines on the whole don't really need it, and those small performance gains can add up considerably in an intensive system. GC is mainly useful for things with undetermined lifetimes. Glue code essentially.
I believe that the theory of evolution by sexual selection is far more important. Same guy, a refinement on his original theory. In that case optimization can take many different forms.

Is House of Cards the next West Wing?

On topic: the issue is that despite illegality, if entities can do it without getting caught (i.e., if the win an election for executive office, they can muscle the government office to cover up the crime as needed), then it's still a huge problem.

It's about expected risk vs. return - and so far we don't know what that calc looks like or who's taken the risks.
If you use shared walls you will need proper soundproofing, and you can't do that in wood any longer. You'd have to build in bricks instead of wood and sheetrock, and if you do multistorey you'd have to put in a soundproofing layer in the floor as well.

It's a quality-of-life issue, and it's especially important to keep the peace in a confined space.

A colleague from Kenya said this: "If you can hear your neighbours you know you live in a slum." Americans have gotten used to poor quality in construction, which seems part of the appeal of single-family housing in the US, even if you plunk down half a million dollars it's still sheetrock and chipboard, it's shocking to see for any foreigner.

For this purpose, and on this scale, what you suggest is entirely unfit for purpose.
I find it amazing that they actually got the correct answer.
How on earth did they guess that?
Really? I don't know about GPUs? That's news to me! Did you know that the precision of the fast reciprocal square root on NVIDIA GPUs is 1 ulps out of 23 bits? That's a world of difference away from 1 ulps out of 7 bits. I wouldn't touch a 7-bit floating point processor. Life is too damned short for that.

And that's because I have spent days chasing and correcting dynamic range errors that doomed HPC applications that tried to dump 64-bit double-precision for 32-bit floating point. It turns out in the end that while you can do this, you often need to accumulate 32-bit quantities into a 64-bit accumulator. Technically, D.E. Shaw demonstrated you can do it with 48 bits, but who makes 48-bit double precision units?

I stand by the computational tripe definition (with the caveat that Hershel has now posted an app where this architecture is possibly optimal). My objections to the broad extraordinary claims made in the presentation above.

And hey, you're a game developer, let me give you an analogy: would you develop a software renderer these days if you were 100% constrained to relying on mathematical operations on signed chars? It's doable, but would you bother? Start with Chris Hecker's texture mapper from Game Developer back in the 1990s, I'm guessing madness would ensue shortly thereafter. Evidence: HPC apps on GPUs that rely entirely on 9-bit subtexel precision to get crazy 1000x speedups over traditional CPU interpolation do not generally produce the same results as the CPU. If the result is visual, it's usually OK. If it's quantitative, no way.
I was just about to write, "If you have a blog, I will eagerly add it to my feed reader." But I looked at your profile, and you already do! Very exciting: http://micheleincalifornia.blogspot.com/
I don't entirely agree with that view. My ex was career army, thus I am theoretically entitled to free medical care for life as long as I do not remarry. My bills are not "medical bills" per se. Getting well was not about pursuing drugs and surgeries. It was about figuring out how to feed myself better and live in a manner that accommodates my condition.

I previously wanted to be an urban planner. I think the poor quality of a lot of the housing stock in this country contributes to health problems, as does our car-centered lifestyle. I have lived without a car for several years now. It is something fairly challenging to pull off in the U.S. (I now live in San Diego county, which has good public transit, but I was someplace without that when I gave up my car.)

I think the path forward to get people healthier in this country is more complicated than just making sure they can "afford" to see a doctor. I have not seen a doctor in several years. If you are healthy, it matters a lot less whether or not you can "afford" a doctor.

What happens if you run it on itself - eg you do some sort of basic program with a little bit of structure and generate code from it, and then analyze the code, eg to make a graph of it (if that makes sense). Or to put it another way, what are the possibilities of making better tools Mathematica (or Wolfram Language or whatever it is called now) using Mathematica?
1% error is, in some sort of half-assed sense, comparable to a signal-to-noise ratio of -40dB which strikes me as a lot of noise to be adding to a problem.
Homeless people congregate where there are services that are available to them. Predominantly, this means shelter and food. So homeless people will know when they can get food, from where, and this generally means places with high population density (it's much easier to walk from place to place in the city than in the suburbs!). In response to this, cities have passed a lot of NIMBY homeless shelter laws in their urban centers.

In Atlanta, there is a homeless shelter that is being closed down (it's currently in court) and the shelter can't relocate within the city because of laws on the size of homeless shelters. They were grandfathered in when the law was passed.

Source: I've spent a significant amount of time working with homeless shelters and on homeless policy.
I think that the standard form of this question assumes that the water+ice is initially at 0°C, so that there's no net warming of the water, only latent heat of melting.

Conversely, one could compute what relative volumes of ice and water would be required to arrive at a final temperature above 0°C. It's also possible (actually: likely) for ice to start at some temperature below 0°C, typically around -12°C for home refrigerator/freezer units.

So let's say we're starting with room-temperature water at 22°C, ice at -12°C, and a ratio of 50-50 water to ice, 100g total.

Latent heat of fusion for water is 80 cal/g, and latent heat is 1 cal/g.

We're heating 50g of ice by 12°C and then melting it. Additional heat, if necessary, is drawn from the environment.

The ice absorbs 200,000 calories.

Subtracting 200,000 calories from the 50g of water would cool it by 4000°C, not counting heat of fusion, or would pretty much freeze all of it solid, if we do. Or conversely, the water can release at most 1100 calories of heat energy before freezing. Working backwards, we find that our 50g of water would require only 12g of ice to cool it to 0°C, or a ratio of roughly 1g ice to 4.2g water.

How is that style of living, expense wise? Would you estimate the cost of boat/maintenance/marina fees to be roughly comparable to renting, or does it cost much more?

That is the sort of thing that appeals to me, but I haven't really looked into it because it seems out of reach.
I actually have several websites. Assuming you are interested in homelessness per se, you might also be interested in this site of mine:

Apple Airplay – Fix Sound Coming From Laptop Instead of TV
Great part: "Who knows better? These random people chattering on forums - I won't mention any names [obviously Hacker News]? Or Zuckerberg himself who knows all the numbers and is actually betting his money. [WhatsApp] must be worth $19 billion if Zuckerberg was willing to pay $19 billion for it, cause he's no idiot."

Reply to below: I wouldn't nitpick the fact that he says WhatsApp "must" be worth $19B. This is an interview, not anything logically formal. The main point is that Zuckerberg is actually putting money on the line and has personally seen all of WhatsApp's numbers. Compare this to the peanut gallery on HN.

It's incredibly cheap, but you need to spend some time doing boat-things like painting fixing rust, etc. Timewise it's probably comparable to a house.

I bought the boat in Holland for around $50.000 in cash and spent around $10.000 fixing it up with insulation, heating, toilet etc. So basically all I pay now is marina rent ($100 a month) and diesel for heating and electricity.

This is in Copenhagen btw.

I disagree. The situation describe continues to exist both in the US and (more particularly) outside it. It's not always structured to make the employees utterly dependent and in debt to employers, though (usually for lower-skilled workers) this does remain the case, and is a key argument against "company towns" or other forms of employer-supplied housing in the absence of other competitive housing markets.

And the point you're trying to make about immigrant or periodic labor is precisely the problem that applies to serfs: they lack the means (or legal ability) to make their own discretionary housing arrangements.

For higher-skilled workers, who have other employment options, this typically isn't the case. Also where employees who operate under union or similar collective bargaining arrangements.
