Original paper: doi: 10.1002/anie.201302577

From their paper it is mentioned they have a 40 nanolitre/min flow rate (25% desalination rate, 99% is considered safe to drink water).

They use an electric pole to generate an ion depletion zone, their problem right now lies in the severely limited flow rate and desalination rate. From my understanding the 25% desalination rate does not compound linearly and decreases in efficiency as the concentration of salt ions decreases.

Additionally their flow rate is 0.4 microlitres per minute, this would equate to needing 625 000 channels for one pass only to get 250mL / min. Scaling for microfluidics isn't simply using a larger pipe size, microfluidic devices largely operate with minimal forces and a Reynolds number of 1, that doesn't hold as you get larger.

The other big problem here is that this requires pressure driven flow, to do that they made two reservoirs of uneven height on opposite ends to drive flow. Again this is very electrically cheap (picowatts) when dealing with such small and perfect flow conditions.

The biggest problems they need to address are the low filtration rate and the low flow rate, it does not seem like there is a simple answer to the first, they do state that they are conducting a larger scale experiment that they will publish later.

I largely suspect that the larger scale experiment will fail in efficiency as another group (doi:10.1038/nnano.2010.34) who also uses a ion depletion zone (albeit by a different mechanism) found after publishing that they were orders of magnitude (10^3) too low in their predictions.

If anything this will perhaps be better than small, portable RO setups but not replace large factories which are actually pretty efficient.

I've got certain friends working for the gov't at three letter agencies that this year have been explicitly told they are not allowed to attend DEF CON either under the banner of the agency or on their own time.

This was announced before this post by DT though.
Read. That's why I mentioned Apache and Nginx, since the Google SPDY team has focused on making sure that there are plugins for each, plus CloudFront support, so that it can be applied "to the little guys". And in turn, I would ask you: Have you not used Web Sockets? How about HTML5 Web Components? New JS functionality? As "hackers", I would expect more excitement than this -- since you're going to enable a whole new generation of low latency cell phone apps, OSes based on web browsers and apps for them (e.g. Win8.1, ChromeOS and Webkit) and do so in a very standards-based way, rather than ad-hoc distributing SPDY through your proprietary browser. Short of security flaws like SSL's header compression, what could go wrong? :)
Do you think they clean your local city water? They don't. They filter it a bit, then add chlorine to deal with biologicals, and that's it.
Is he playing Lego games in Chrome OS or are you running a different system on it?
I would like to just add the small addition of "so?". Bums in seats only increases the quantity of people on your payroll, rather than the amount of software produced, the amount of issues resolved or the quality/quantity of software produced.

The company I am with just had a disappointing experiment with hiring some offshore developers in India, and although fingers can be pointed at bad recruitment or any one of a dozen reasons, there were 3 folks there and all code that came in was of such low quality then it was rewritten by someone before being released to a client.

3 people that our company had in India were replaced by 1 person on-shore.

One of the biggest issues is that there is still a race to the bottom on pricing in India (and many other countries), this does not produce good products but foreign companies are still eating it up, which produces demand and drags people who otherwise would by unemployed become a developer. This is the reason why the number of developers in India is increasing so much. But the issues with low cost/low quality development are starting to become apparent when projects become more expensive.

As has been said before by other much more articulate than I, I am not worried about this.
I don't know of any studies on the subject, I'm just reasoning that if you have enough money to do actual long-term investment you must have some form of income, so if it falls through you still have income. It's not like gambling where you can addictively throw away every dollar you have in a day. If you 'invest away' all your money, you can uninvest it the next day.

Also: It's not 'negative impact' as a binary check, but looking at the massive cost of medical bills. And seatbelts are enforced on public roads, not private land. Investment is fundamentally a private action, which should only be restricted in very serious circumstances.
What is Impact Factor?
The impact factor was devised by ‘Eugene Garfield’, the founder of the ‘Institute for Scientific Information’ (ISI), now part of ‘Thomson Reuters’. Impact factors are calculated yearly for those journals that are indexed in ‘Thomson Reuters’ ‘Journal Citation Reports’ (JCR). - See more at: http://blog.editeon.com/#sthash.cOgTXba5.dpuf
would those experimental users have given up right when the browser reported "Missing </p> tag"?
Just got this confirmed through an anonymous source at DEF CON, it has indeed been canceled. With feds no longer being welcome there simply would not be enough money made from ticket sales to pay the costs for the venue.

Welp, I just spent an embarrassingly long while reading the 160 pages of the findings. I'm now of the opinion that Apple is probably guilty of antitrust violation. Judge Cote admits (on page 157) there's nothing inherently wrong with MFN clauses, simultaneous negotiation, price caps, or any of Apple's contracts. It's even plausible Apple could have escaped culpability, were it not for evidence that Eddie Cue and Steve Jobs knew that the publishers already wanted to raise prices, and willfully provided them the opportunity. An MFN clause was meant to protect Apple, but, because of Amazon's artificially low prices, it also had the effect of tending to indirectly trigger an industry wide switch to the agency model with increased prices, and Apple expected this. It was this expectation that apparently elevated the act to conspiracy.

Despite that, I must admit, I feel ambivalent about the ruling. Amazon's below-cost retail pricing appeared to have otherwise prevented Apple from even attempting to enter the market, at all, unless they came up with some way to profit. I guess they picked the wrong way.

Devil's advocate: that shows they are effective and crime would be even lower with increased budgets.
I actually really like the marketing of not offering all champions directly, KNOWNING that you can acquire champions without money but with points you get from playing the game.

When you start playing LOL you have to choose from, I think 6 different champions? Which is pretty limited but let you master those 6 before changing them the next week to 6 new champions. I learned the game without problems this way.

DOTA2 let you play with all the champions directly, oh boy was I lost and still am 200hours of games later. I only play "random" so I can learn every hero but I still haven't played 25% of them I would guess.

Also I know many friends who bought champions on LoL, I think it's a very good source of income.
> It's not like gambling where you can addictively throw away every dollar you have in a day.

It's not?

> If you 'invest away' all your money, you can uninvest it the next day.

Not if it's gone.

In the early years, DefCon founder Jeff Moss used to say "if you're 20 and you're working for The Man, you're a loser,"... "Ten years ago, Moss said 'if you're 30 and you're not working for The Man, you're a loser.' And now he agreed that at 40 he is The Man.'"
Repo men.

There is at least one company that works with repo men - they put ANPR cameras on the repo men's dashboards, it records every plate that comes into view and uploads it in near real-time to a central databases along with gps info. Any repo man who subscribes to the service can put out an alert for a plate, once that plate of interest shows up in the central database they get a text message telling then when and where it was scanned. When I first heard about these guys a few years ago they already had a very large number of repomen participating in the service.

I am not surprised to hear that the companies have expanded their market beyond repomen, that is the nature of databases - once you've got the data centralized all kinds of ideas come up for how to exploit it.

Actually when I was at NetApp we got pretty good at figuring out ECC failures. Just write a program that allocates 1GB array. Fill it with random data and compute a MD5 hash on it (you can do that fairly quickly). Now recompute the hash once every 5 minutes for a month. Run that on 125 instances. (that ends up being 1 Terabit of data btw) which makes a good detector for cosmic rays if it isn't ECC protected :-).

It's funny, isn't it? We gave out more domains to speed things up, but now it slows us down (referring to your link).

I would highlight that HTTP 2 > SPDY as far as standards go, and the "beta" protocol of SPDY is already at 55% market share including IE 11: http://caniuse.com/spdy

For those who are interested in speed optimization for 2013 and beyond, plus why SPDY's faster-than-SSL descendants are crucial to the web's success, have a look at http://www.igvita.com/slides/2013/breaking-1s-mobile-barrier... -- I believe there's a video out there too somewhere. Edit: Video link is on first page of the slides.

What's interesting too is that this talk focuses as much on what's achievable without SPDY as what might be with, down the road. We really need faster SSL negotiation for that first time connection cost.
Still doesn't sell massive war - shortages are political in regions where people generally have nothing.

Wars - technological ones of the type major powers would fight - are expensive. Far more expensive then any amount of desalinization we would need to build.
Yeah. It's too bad there aren't free web servers out there that everyone can use that implement these protocols. Oh wait, there are.

By making things more efficient, HTTP 2.0 is really going to make startups spend more money. Oh wait, no, the opposite thing.
just downloaded arq. looks amazing, can't believe I didn't know about this before.
The process doesn't even have to be super efficient

Economics are important. We didn't go back to the moon because it was too expensive, and we're not going to see massive-scale desalination because it's also too expensive: http://physics.ucsd.edu/do-the-math/2012/10/the-energy-water...

California uses 46 billion gallons of water per day.
Supplying 25% of this via desalination would require 36 GW of
thermal-equivalent power. California runs on 30 GW of
electricity, and a total energy budget of 262 GW (thermal;
from oil, gas, coal, hydro, nuclear, etc.—according to the
EIA). That’s a substantial amount for 25% of our water needs.

A "ten dollar glass of water" isn't even the big issue. Agriculture requires water, and expensive water means expensive food. Expensive food means people die, mostly from bullet wounds inflicted by people who are hungry. (I hardly need to provide citations for the number of wars resulting from food shortages)

AFAIK this is primarily for the purposes of avoiding the court system. Things that are classified seem to be dealt with by the rubber-stamp FISA courts instead of the actual judicial system so they can avoid being challenged in the light of day.
>How does it compare to League of Legends?

The biggest different between Dota 2 and LoL is pricing model.

Dota 2 is free. Really free. You have access to 100+ heroes from your first game and there isn't a single thing you can buy that has an effect on winning or losing a match. It's all skins, alternate announcers, and other stuff just for fun.

LoL is free... to play. There are a set of heroes that are free at any given time which is constantly rotating. You have to pay to unlock heroes permanently or can unlock them very slowly over time. You will never unlock everyone without paying money. There are additional other systems you have to level up, or can pay to level more quickly, that provide small bonuses to character attributes in game.

This effects more than the price.

For example in Dota 2 one of my favorite modes is "Reverse Draft" where each team picks the OTHER team's heroes. So you try and give your opponent the worst team you can think of. Something like this is impossible in LoL because every person only has access to a small set of heroes.
Don't want to debug it? Don't turn it on. The only reason you would is if it had more benefits than drawbacks. Standards bodies make standards, they don't force people to pick one.
I wouldn't be surprised if this was a serious effort by the con to reduce drama and distance itself from the intelligence and law enforcement communities.

Despite practically being in bed together, and all that is supposed to change just like that? It seems like some sick joke, from the outside looking in of course…

Then again, it has more or less always been this way and maybe things seem different now that the tide has receded a bit…
I will attempt to translate Jeff's short message:

In light of recent events, this is not an opportune time for recruiting and so the feds will not be attending the conference in their usual numbers. However, they will of course still be monitoring all communcations at the event, so they will be there in spirit.
See! You used it right there, and my browser didn't even display it--must be conforming.
The absolute minimum energy you need is 2.2kJ per liter. A 4x4 inch solar cell could do that in about 2 hours.

However I suspect that you'll never actually desalinate water for that amount of energy in a portable system.

The very best commercial systems manage to do it with about 3 times the energy of the minimum. More common ones are about 10 times the minimum.
There are diminishing returns. You could easily have eight people each working a one-hour shift on an assembly line once they all know the task, but writing code that way would be absurd--they'd waste almost all the time explaining how they intend to proceed with what they only just started on.

"ITO comes from the metal indium, which must be mined"

The bulk of our indium supply actually comes as a byproduct of zinc mining.

As for alternatives to ITO there are many startups working on next generation technologies. Off the top of my head I can name Cambrios (mentioned in the article), Innova Dynamics, C3Nano, and Sinovia Technologies.
I just want to say, there was a time once when I was overly addicted to playing dota. One of my workarounds whenever I felt I had binged too much was to whipe my windows install and go with Ubuntu. It kind of worked, but eventually I'd just go back. I even went so far as throwing my windows license in the bin and snapping my install disc. Time and time again I'd just download a cracked version and burn a new disc...

Eventually I overcame the addiction by replacing the habit with going to the gym 4-5 times a week. Now I spend my time in windows playing with the directx sdk instead of on Dota.

Not really sure what value this comment adds, but I guess soon even Linux won't be a semi-safe-haven for Dota addicts (p.s. I have an ATI card so wine wasn't an option for me).
The management is likely to go home and play with their kids while you grind your bones in office.

however, you don't often play with people with a large rune advantage or disadvantage.

" … with customer provided access and permission can allow HP support … "

Which, cynically, could easily be read as "with the storage device on a network, and with a company policy requiring support staff to request permission before using it".

Maybe these things aren't _intended_ to be directly internet connected - but there's a _lot_ of gear that ebds up that way without ever having been designed too. Even HP admit: "This vulnerability could be remotely exploited to gain unauthorized access to the device."

And from the end of the article - it seems at most: "And, of course, there's the "reset factory defaults" option, which would nuke all a user's data." - still not a "backdoor", but somewhat worse than just "a reboot".
I was assuming Defcon 21 would be down on fed count this year due to 1) the sequester hurting travel budgets and 2) recent (well, in the past year) high profile wasting of money in Las Vegas by the GSA.

There's also OHM running in parallel, which will draw off some of the European attendees (probably not law enforcement/intel, though). If I got to pick between OHM and PW/BS/BH/DC (all 4 running in Las Vegas that week), I'd probably pick Ohm.
Devil's advocate: Why would they need justification to at least keep records of where your licence plate has been in public? What expectation of privacy do you have?
Stateless? What about that hack known as cookies? Aren't they useful? How about HTML5?

And what happened to the calls for SSL everywhere? Defending your cookies from the NSA and MITM? Of course we need two protocols, perhaps more than two. I'd love to see something more interesting happen with multicast given talk of IPTV in 4K.

I'm shocked that your only objection ends up being the protocol name. Worse, it's the version number. But hey, it is semantic versioning... Don't use it if you don't want to. It's not like anyone else will notice if your site is already fast because it's one request with no state.
Spain's tourism boom keeps troubled country partying
Madrid (CNN) -- Summer could not have come soon enough for Lloret de Mar, a tourist resort north of Barcelona that is brimming with young travelers from Britain, Germany, France and Russia.
By day, they flock to the main beach with its steep descent into the Mediterranean, and by night they crowd the streets lined with clubs called Londoner, Hot Spot or Zoo.
It is a scene repeated up and down Spain's extensive coastline along the Mediterranean, the Atlantic and its famous archipelagos, the Balearic and Canary Islands.
Spain's economic crisis is in its sixth straight year yet tourism, worth 11% of GDP, is holding its own, one of the few bright spots on a bleak horizon.
Summer, of course, is high season for tourism in Spain. The country is the world's fourth-largest tourist destination, behind France, the U.S., and China, according to the UN's World Tourism Organization, based in Madrid.
The average car is driven say 10k miles per year. At 20mpg that's 500 gallons of gas. At $4 per gallon, it's $2k. At $8 per gallon, that's $4k. A difference of only $2k.

I'm not sure that the money on wars is well spent (even in a callous, dollars only sense) if it's saving the average household $4k a year in gas money (two cars).
Actually, yes, the feds are using Section 215 of the Patriot Act to get FISC orders on all metadata of Americans' domestic phone and internet communications from ISPs and phone companies. The feds are leveraging a theory that you have no privacy interest in your metadata, thus no 4th Amendment violation.

It's not clear at all that this is legal, especially given the Supreme Court's recent ruling in Jones, requiring warrants for GPS tracking of automobiles.

"The new method requires so little energy that it can run on a store-bought battery."

What a silly measurement. I can buy a laptop battery or a car battery at a store. Also it does not give any idea of how much water could be produced from the battery. A teaspoon per battery probably isn't too great. (Although at the moment they get only nanoliters of salty water from it of course).

DOTA and LoL teeter-totter as to which one has the most unfriendly players. currently, LoL around level 20-28 doesn't seem very bad. i hear Ranked (level 30, organized/draft (both teams ban some champions and then choose them, elementary school sports style)) is a bit less friendly.

> I know asking for help when you really need some isn't wrong, but how did older programmers tackle that conceptual "blank page" syndrome, without all that information abundance, when they didn't want to annoy their coworkers?

Books. And desire. And breaking things down and doing one step at a time. "Information abundance" is a mixed blessing; it makes it much easier to find information, but it makes it a lot easier for people to get out of the habit of working things through.

Actual investment (to be distinguished from day-trading) is not an addictive action. There is no feedback loop.

What crazy definition of investing are you using where you have any reasonable* chance of losing all your money in less than a day?

Compare that to the near-100% chance of losing your money if you spend a single hour betting all of it at casino games.

*let's say 1% or greater
Note the "this year". Defcon is just looking after their branding. If they had concern for privacy they wouldn't have had the NSA directory keynote last year and let him lie to their audience.
Because their customers are the pointy-haired-bosses who're asking "Why the hell to we need to wait for them to send a service tech out? Why can't they fix this online?" when shit is actually going down - rather than the network/storage/security guys who point out the risks of things that haven't happened yet.
