Researchers achieve 'holy grail' of battery design: A stable lithium anode
There are a lot of similar "custom men's dress shirts" services around now days (though good job on the cool tech!), but none of them offer fashionable men's long sleeve shirts, in styles such as those mass marketed by Rag and Bone.

As someone with insanely long arms, who already gladly pays $200 per shirt for off the rack, I'd gladly pay for a service that offered custom tailored men's fashion shirts.

Any thoughts of moving towards that market?
Pages 4/5 of the Stardock 2014 report have a couple of graphs on mobile revenue and PC game revenue vs. sales ranking, https://news.ycombinator.com/item?id=8092753

"Once a game of piece of software leaves the very top of the sellers, the income fall-off is severe. Our poorest selling DLC for PC games generates more income than nearly every iOS or Android developer app we've gotten numbers for."
No I mean Google, the company. Specifically, Google pings your location at intervals (building their Location history, linked above). For this specific use (which isn't tied to Google Maps), it's done through the Google Play Services, which, under the Location setting on your phone is listed as "Low battery use". This indicates that it is not using the GPS chip, but relying only on WiFi and Cell tower triangulation.
"A group of pensioners came into the lab twice a week for six weeks and went hell for leather on an exercise bike for six seconds.

They would allow their heart rate to recover and then go for it again, eventually building up to one minute of exercise by the end of the trial."

It actually sounds like they work up from 6 seconds in their first session to a minute per burst after a few weeks. The 6 seconds number is incredibly misleading in general, since this is just where they started out to get acclimated. It also leads me to believe that in the long run you may have to keep increasing this interval to get additional benefits. (Much like any endurance training.) I can imagine after a year maybe these folks would need to be doing 10 minute bursts. This would be awesome of course if they get there, and is still an improvement over the treadmill slog, but the headline here seems to make people think there is some free lunch in that you only need to do 6 seconds of exercise at a time to get healthy.

> I don't think there is any privacy expectation there, any more than there would be if I took my "papers" out of my desk drawer and threw them out my car window.

Isn't this a bit more like the cops replacing your trash can with a scanner, though?
Good example definitely. I wonder what kind of money they're making. I also wonder if they would be able to do the same thing in 2014 that they did a few years back when they launched. I perceive the landscape as far more competitive, but I could be wrong.
If you lie to someone in order to induce them to give you valuable private information, that's fraud, not "information you carelessly broadcast". If a Stingray says "Hi, I'm a cell tower, connect to me!" that's not at all the same as mere passive recording.

(Now, mind you, mere passive recording of cellphones without a warrant is _also_ an illegal search as far as I know -- or would be if there were still unencrypted data to passively record. But that's totally unrelated to what a Stingray does.)
I think 100m is the best they can guarantee. You may get better results based on the data they have in your area (especially WiFi triangulation), but it's not guaranteed. In any case, the best they have for me is: http://imgur.com/vVbqSvr which is coarse enough to not actually provide much data. I could have been to any one of a dozen or so businesses in that area.
Semantically, it could really go either way. If I 'carelessly' broadcast a letter via the US Postal Service to my grandmother in Hawaii, I have no way of ensuring that its secrets will be preserved in the long journey between my house and it destination.

Similarly, if someone forged a USPS mailbox, placed in front of the post office, and I 'carelessly' dropped my letter in, then by your interpretation, I am a damned fool.

This isn't an area where I'm particularly savvy, but if a private citizen were to stand up one of these mailboxes, it would be a federal crime. I understand that the corollary is not identical, and I agree that it's hard to parallel technologies to their real-world counterparts, but if a private citizen set up one of these towers, they too would be charged with some kind of wire fraud.

In the absence of a warrant, I see no reason the government should have any elevated privileges here.
Thanks for the detailed answer. I see why MD5 is harmless here, now.

I still wonder why anyone does anything with MD5 anymore, especially in an application like GPG... if it is known to be weak... It makes the argument why it is still safe in this situation much more subtle and involved. From all the crypto gurus, we hear 'MD5 is unsafe, do not use it anymore!!' and then in PGP/GPG, MD5 is still used because, well apparently for historic reasons and because one can.
As a non-expert in these matters, this looks very odd. It seems to (needlessly) make matters more complicated and involved, more complex in terms of the necessary analysis, and on the other hand unnecessary complexity is (rightfully) despised by the same security people...

If they'd use SHA256 or similar, one could simply assume all of the properties of an unbroken cryptographic hashing function and throw out the MD5 code.

So in the end, the only valid excuse here would be history+inertia.
That is probably true, but if you read the newspapers you'd think otherwise. The US has a pretty good humanitarian track record, but every little thing gets blown up outside of proportion.

And of course, the US has an economic system that the world politically hates. It's not socialist, so it's constantly held up as an example of how bad things can be in Europe. America's economy is huge, very free and not a dictatorship, so every middle eastern country, China, and so on are very afraid of it, making sure that every media available in the country regularly excoriates it. Problem is that the US press picks up on an article from these places on a regular basis and reprints a rewrite of it.

Impressions matter more than actual substance. Otherwise China, or for that matter Palestine, would be looked at very differently.
I am colorblind too, but I solved level 20. I just assumed there were two of the same color. It sounds like I lucked out..

If they've already gotten to the trust screen, they don't need the backdoor to get your data. Your phone is unlocked and the data is available by just using the apps themselves.
I never finished the book, but I'm reminded of Malcom Gladwell's Blink whenever I have moments of subconscious problem solving. It's a strange feeling: insight followed by a confused determination as a my conscious mind pieces together what the sub figured out.
the courts have usually interpreted the fourth amendment based on the effects of technology, not the mechanisms of technology. they don't have to understand how stingrays work, they only have to understand what impact stingrays have on your freedom from search.

that's why the court ruled that thermal imaging (in kyllo v us) is a search. sure, the mechanism of the technology is that you're carelessly broadcasting your heat signature through the airwaves, but the effect is the same as if the police had entered the home - they can see inside it.
The price differences are less important there rather than the total system balance - locations of supply and demand, and the exact current amount of supply and demand at each location at each moment.

In a connected power system, if power 'needs' to get from A to B, it won't only flow through the direct connection, but along the longer loops as well, which often creates 'transit'. For example, in that map from NO5 to SE5 through Denmark, and from NO1 to NO3 through Sweden. This is normal and pretty much unavoidable - it's more efficient to optimize the flows to reduce total system losses, and then just try to bill everyone fairly.

You can't simply set a specific flow amount (well, you can force it to 0) to some country and keeep it there without mucking up the rest of the system, unless high voltage DC links are used to connect separate power systems.
Am I guessing correctly that this isn't at all related to negative energy? When calling this a temperature below 0K - isn't this shoehorning the concept of temperature onto something it wasn't meant to do? Isn't this transition from a positive temperature to a negative temperature system non continuous, as in it needs to be set up with different properties? I'm thinking a more intuitive approach would be to put an additional system defined factor into equations defining a relation between temperature and entropy - this factor would usually be +1, but can be -1 under certain circumstances.

But hey, IANAP.
Perhaps that's also why the raw ones tasted sweeter and better, they were both from Thailand. I know glass is the most inert but it doesn't seem like any of the brands sell glass bottles - pretty sure plastic would be the next best. Yeah, definitely try the raw when you can, I can't believe how awful the non-raw stuff taste in comparison - it's eye opening
it has nothing to do with the article. its also unfortunate that this person was so upset over some downvotes.
A curiosity of physics is that you can set up systems with a negative temperature, but you can't ever get to zero temperature, from either direction.

Fusion is big. Fusion could be economically/societally dangerous. If fusion is developed very incrementally no big deal.

If a real breakthrough occurs making fusion cheap and easy, a huge chunk of economic activity could be made redundant overnight.

Huge social unrest, starting in the middle east and U.S. to a lesser degree is possible as incomes vanish.

Hopefully will replace fossil fuels incrementally, just as the transistor replaced the vacuum tube incrementally, etc.

A huge breakthrough in affordability and practicality could be dangerous though.

By publishing their results to the broad masses it will be hard for concerned governments to discredit them.

It is a distinction without a difference. Stingray becomes part of the mobile network. That's what enables your phone to connect to it. Your analogy is ridiculous. Throwing your papers out your car is clearly an unusual act. Your phone is behaving to spec when connecting to a Stingray.

It's disturbing how some educated people can excuse a police state. It worse than the police themselves because they ought to know better what the dangers are.
Bespoke software is a bit like building a one-off car. Some chunks, like the basic framework (e.g. Rails ~= car engine) are commodity, but the bits that are custom aren't really worth more than scrap metal to other people unless their requirements are very similar.

And even then, if the people who were working on it aren't part of the sale, the new owners are going to face a chunk of cost just getting familiar enough with the project to alter it in the right direction. Most people will be better off starting from scratch.

Unless what's been developed is a fairly complete and self-contained solution to a common problem, I think it's hard to see it being worth much at all.
At Front Lines, Bearing Witness in Real Time
If I total the numbers you present, they had a net $2.2b of positive income (i.e. profit) since 1997. Small profit as a percent of revenue since 1997, but overall profit. The first quarter of this year had an operating income of $108M and the second a loss of $126M. Are you suggesting that the remaining two quarters will have approximately $2.1b of loss?
But neither is the pursuit of money any sort of notable goal. It's sort of like, "oh, well, get in line behind the other hoards of people who also want to be rich."

Nobody will care about what you do if this is your goal. On the other hand, if you can tell people "I want to make your life easier by: filling a market gap, changing an industry for the better, making X easier to use, making Y more affordable" then people will care. Thinking more about others than yourself is also probably a good way to actually find a good business!

"I don't think there is any privacy expectation there"

I think the expectation of a typical cell phone user would be that there are not people other than phone companies for the purpose of providing service slurping up data from their cell phones. Same way I don't expect the kitchen at a restaurant to tell the world what meal I have ordered.

"The police should not need a warrant to access information that you carelessly broadcast onto the public airwaves."

Isn't this similar to the problems that people have with being tracked in retail stores? And for that matter what is the legal difference between the police collecting certain data and, say, a business person collecting that data? And perhaps selling it to the police? (Question not a statement).
The fact that Ph.D. holders have the lowest unemployment rate is not at all surprising, given that these people have all undergone extensive selection to be smart and hard-working. This would still be the case even if holding a Ph.D. were completely useless, so it’s not really clear how much the unemployment rate is decreased by actually holding the degree.
> I realized that doing a Ph.D. would probably be fruitless. How did I determine this?

Well clearly it takes someone going to the best math departments in order to realize that within a hierarchical organizations wherein tenured employees can supervise a lot of grad students in the span of their career, only a few of those grad students can really get a job similar to their supervisor. Was this really a revelation?
I'm really really hoping Hopper can catch up to IDA. I'm still not good enough with assembly to make much use of either, but the free version of IDA can make some really nice flowcharts which are pretty helpful.
Thanks! So if I do make a signature using GPG, it might still silently sign just an MD5 digest, if I didn't (re-)configure it properly? That sounds scary...
yeah, but we both know that evidence is farcical. Epic System's practices are pretty well documented. And just this week, I was hit up by a recruiter looking to pay "up to 120k" for a data scientist with 4-7 years experience, ms/phd, and experience with hadoop and large-scale stochastic optimization. It's not hard to figure out why someone's paying for a recruiter to try to fill a job with a stupid low salary.

Refusing to support companies asking for friendly visa changes for free is employees' best bet at getting said companies to support employee-friendly changes.

49.960 is pretty exact; the frequency can reasonably deviate much further. Some systems try (tried?) to keep a 'daily average' of 50.000 hz, but the grid will run quite okay at 49.960 hz, at 49.900 hz and at 49.000 hz; not that it's recommended but it's an option if there's a supply/demand disbalance.
I'm sure you're a great guy and just coming across negatively in this one comment, but you sound less pleasant than the vast majority of McKinsey people I've ever met. It's a bit odd in a comment complaining about consulting douchebags.
Both Yandex and Baidu are just copying Google's every move though. It's competition, but there is little innovation going on.
This was a pretty funny comment and I know its ironic, but still it is useful to point out that RedHat has a lot of products, including Middle-ware and cloud solutions that these partners resell for good money. Since Russian business is buying them, it does find them useful and thus sanctions are biting someone.

Food for thought - what are the implications for Russian big-business of being forced out of the global cloud-services infrastructure?
This is based on the TitanEngine. http://www.reversinglabs.com/resources/open-source/titanengi...

Is there a word for open source that has no revision history? (there's just a .rar file on that site). 7zip does it too and it drives me crazy.
I agree with you on most of it, but I'm not convinced it's as clear as you say it is. Depending on how this works it may be much more like handing your 'papers' to someone dressed up like a Verizon representative with all the proper paper-work to prove it, but actually happens to be a police officer undercover who isn't going to deliver your papers at all.

IMO, the difference in my opinion depends on whether it's just collecting data you were sending out anyway, or if it's pretending to be a cell tower from a specific company and attempting to get your phone to send-out data it normally wouldn't have done.
lambda's already replied about the relative trustworthiness of different media sources. However, lambda's earlier post was limited to why a US company can interfere with the contracts of non-US companies. The problem, of course, is that Red Hat can get into legal trouble if it does business, directly or indirectly, with the targeted companies, but Red Hat's independent partners are under a different legal system, and may well get into trouble by breaching their contracts at Red Hat's insistence.
>What for? I dunno, many places, the football team, padding the endowment, building new B-school buildings, hiring an army of mid-level administrators.

>Stingrays don't "force" your cell phone to do anything. Your cell phone reaches out and connects to it of its own accord.

A distinction without a difference. That's the nature of the prevailing wireless telephony technology. Users wouldn't be able to receive telephone calls if their equipment didn't coordinate periodically with the cellular system's base stations. Although a system that doesn't constantly leak user's data could conceivably be constructed, that is not what is currently in use. Turning one's phone off to avoid tracking isn't a good solution because then the device has ceased being a telephone.

>Your phone transmits your private data into the aether at the user's direction.

No, nobody directs their phone to 'transmit their private data into the aether' people direct their phones to place and receive telephone calls.

>I think this fact has major Constitutional implications.

I think you're inventing a business case for some group such as Aereo's engineers to form another technology company whose purpose is to engineer around weaknesses in the law.

> The police should not need a warrant to access information that you carelessly broadcast onto the public airwaves.

Telephone calls are private. Nobody would select 'carelessly broadcast my information' in their privacy options. The change in technology doesn't render privacy protections in the law moot.

>I don't think there is any privacy expectation there

I hope you're in the minority.

>(another example of judges not understanding technology?).

Perhaps they've rightly noted that a particular weakness of the technology du jour is unrelated to the individual's legal right to privacy.
Go is pretty nice for parser/compiler applications because it is fast and the runtime doesn't take too long to startup.

Would it be possible to determine if your phone was connected to a Stingray instead of a regular cell phone tower? Could you have multiple phones spread out geographically and attempt to triangulate the "cell phone tower" itself, to see if its moving?
> Fusion could be economically/societally dangerous.

Fusion is the opposite of that. Cheap energy is the greatest driver of economic growth and social prosperity the world has ever known. The fact that fossil fuels are becoming increasingly expensive and at the same time destroying the global climate is nothing short of an unmitigated disaster. Anything legitimately capable of reducing energy costs while fighting climate change is rightly hailed as an economic and social miracle.

I will keep this in mind. Thanks!
What's important is not only maximum current, but magnitude of the magnetic field. Yes, these quantities are closely related, but fusion reactors are interested in dense magnetic field, and superconductors often break down after some magnetic field. For example, according to this site, the record is 17.6 Tesla - http://www.kings.cam.ac.uk/news/2014/world-superconductor-re...
The Russians just need a little Lebensraum. The West has continued its policy of containment even after the fall of the Soviet Union. This can be seen in the aggressive expansion of the EU and of NATO. It is necessary that Russia have scope to influence its neighbors and build partnerships in order for it to be a free and prosperous nation.
Assuming it looks the same as a normal tower, you could still make a map of existing cell phone towers (crowdsourced from the phones themselves, or there's probably a regulatory filing somewhere with the information). If your connection is better than it "should" be, you may have found a Stingray.
