> Using tape, rubber and a tiny glass ball, researchers transformed an iPhone into a cheap, yet powerful microscope able to image tiny blood cells. They’ve also added a clinical-grade cellphone spectroscope that might be able to measure some vital signs.

> And with a few dollars and some patience, you can do the same to your own phone. (See instructions below.)

> “It still amazes me how you can build near-research-grade instruments with cheap consumer electronics,” said physicist Sebastian Wachsmann-Hogiu of the University of California at Davis, leader of a study March 2 in PLoS ONE. “And with cellphones, you can record and transmit data anywhere. In rural or remote areas, you could get a diagnosis from a professional pathologist halfway around the world.”
I don't know about this particular implementation, but MAKE Magazine recently featured a similar DIY project (although this one doesn't use an iPhone, and instead projects the image onto a wall).

Real monetary expansion is much greater than 2-3% on average. The price inflation they calculate might be 2-3% but look at college or healthcare costs. That new money finds a home somewhere and I'll tell you now that that's where it ends up these days.
How would an economist get information about a bubble? Magic? Until they burst, anything you could say about them is speculative. Everyone talks about how education is the next big one, but education and real estate are such different markets they might as well be on different planets. It's impossible to know what's going to happen until it happens.

The housing bubble caught a lot of really smart people off guard. Housing was overpriced, but it's been overpriced for years. You had to have special, insider information about just what sorts of crazy tricks were being pulled behind the scenes, and you had to understand that it wasn't sustainable and what would happen once people started defaulting. Looks easy in hindsight, but you go out there and try to predict what's going to happen in two years.
I live in Japan and the Japanese government, under its Abenomics movement, decided on another round of QE and injected 20% more currency into the market earlier this year.

I get that the yen is too strong and needs to weaken in order to protect the trade balance between itself and other countries.

But the inflation eventually reached us consumers and every day items have gotten that much more expensive.

Now my 10,000 yen only gets me ~8333 yen worth of stuff. If I could go back in time and not contribute the lost 1/6th of my savings in labor I might not be angry, but I can't.

My salary isn't going up either and there is even talk of pay reduction due to a worsening economy.

So to protect myself my choices seem to be:

1. Buy things up before the inflation reaches me as a consumer, passing the purchasing power theft on to the merchants. (possible, but I blow all my money away)

2. Convert that currency to something else that hedges against inflation (and retains its value over time) if I want to not spend it.

I chose #2 in the form of gold.

If you want to call me a goldbug, go ahead.

The Internet is an IPv4/IPv6 dual-stack network. When the topic is Internet access, IPv6 is relevant by definition.

The fact that Korea has shown no interest in following the IETF standard suggests that they're willing to balkanize the network. High-speed broadband will become meaningless if you have to jump through hoops to reach the Internet.

Right. There's no way to disprove theories that are tested in this way. Proponents of the theories being tested could always say that the attempt wasn't large enough, that the officials didn't believe enough in the policy, that the gods were angry that quarter, etc., etc. At some point you need a sound theory to draw back on that does not require this sort of testing to stand on its' own.
The unfortunate question that keeps coming up in my head: does Glenn expect all the journalists of this new enterprise to be as good as him? If you look at his past articles, going back years before the Snowden leaks, he is clearly fluent in what he does. Being a former lawyer accounts for a good part of it. For example he never descends into "liberal vs conservative" "left vs right" semantics. He recognizes that these meaningless labels hinder discourse (even in this exchange, Keller tries to bait him into it, but Glenn doesn't budge). It also seems as if he has some kind of bank (a personal wiki? I must know!) of links to past articles and sources that he can pull from and sprinkle over his claims, a practice that makes for amazingly solid articles.

Like another user said, I've been reading most everything he writes and tweets -- starting months before the Snowden leaks. I just trust that they're relevant to me as a US citizen 99% of the time. Few journalists are worthy of such trust.

What's the problem with belittling as long as it is made in a presentation by which you state your opponent's arguments and tear them with facts, and state clearly when you're speculating?

This is the sort of BS that's destroying journalism. You can argue for a side either honestly, presenting all you know, recognizing you opponent's valid points, but using your knowledge to debunk the other side, or you can be mischievous, ignore and distort facts, resort to fallacies, and generally achieve the effects of empty rhetoric.

Opinionated people are not the problem. Fallacious people and talking heads are.
Sounds like the right solution would be for Facebook to lower the social weight attached to the "friend" bit. They could turn it into a scalar quantity that's boosted when you interact with your "friend" in some fashion, and that otherwise decays over time. When it reaches zero, the unfriending process happens silently and automatically.

That way, if you don't visit your "friend"'s page in x days, they are no longer your "friend." You can always restore the connection later by visiting the person's page -- and of course Facebook would continue to track the link forever as part of their attempt to run their own private NSA or whatever they do with their graph data -- but from the users' point of view, the act of unfriending would become an inoffensive, passive one that no one can be blamed for.

I had a Macintosh Plus when I was a kid. (My dad wrote his Ph.D dissertation on it, and he had a HD and some game disks before I somehow destroyed them.) I remember that computer fondly. When I was in first grade we got a new machine, and we took the Mac Plus out and left it next to the apartment complex dumpster that morning. By the afternoon it was gone. Sometimes, I still think about it...who picked it up, whether they plugged it in and found out it was still completely functional, and if they still have it today.

And if inflation is really high and fluctuating everyone makes the decision to never save in cash which isn't healthy.

But a bit of low level inflation is generally seen as a good thing. The questions over the efficacy of monetary policy as a stimulus tool in all situations is certainly questionable though.

It's also worth noting that independent central banks are a fairly new thing. Inflation levels used to be set by politicians who would notoriously let short term interest over ride price stability.

The Bundesbank was the first independent bank drawing lessons from the horrors of hyper-inflation. Most (all?) developed countries now follow that model.

I'm happy to see this article written, and it will hopefully start to change the attitude of evaluating central bank actions through the lens of 'high inflation bad, low inflation good'.

This whole debate is an unfortunate example of what's called "Partial Equilibrium Reasoning" (as opposed to "General Equilibrium Reasoning"). All things being equal, higher inflation is bad. That's clear. But all things aren't equal, and so appeals to logic about how inflation is a hidden tax on 'the people' and so forth are essentially worthless when applied to real-world situations.

Here's why. One weird thing about inflation is that inflation expectations become a self-fulfilling prophecy, because when people predict inflation, they demand escalating prices on things like 10-year leases and labor contracts, and when they don't predict inflation, they don't.

The situation today, in 2013 America, and not fake-year hypothetical-country in your economics textbooks, is that
inflation expectations are extremely low. They are low because inflation is essentially a by-product of economic expansion, and most people predict that economic expansion will be weak for the foreseeable future.

As it turns out, the reverse of this is true. If people expected the economy to start growing strongly, their inflation expectations would likely rise, which would probably be enough all-on-its-own to cause inflation to rise. Weird, right?

So it turns out that if the economy were to strengthen, one thing you'd notice in the data would be slightly higher inflation. And you'd go, "Well that's no good, but at least the economy is improving!" And you would be looking at a General Equilibrium in which most people are better off even though inflation is slightly higher, because many other things (Nominal Growth, Real Growth, Unemployment, Long-Term Interest Rates for savers) would be moving in the _good_ direction.

This dynamic is why the Fed needs to break the attitude that its job is to keep inflation as low as possible. The worst thing that could happen in the above scenario is for people to think 'Uh oh, inflation is going up, that means the Fed will probably raise interest rates', which would have the (expected) effect of reducing economic growth. But we need growth! And we need to accept that a few percentage points of inflation will be a by-product of that in a healthy economy.

So to summarize, the issue here is not that inflation is good. It's that there is more to this picture than inflation, and that if you have a dogmatic belief that inflation is evil in all situations and should be avoided, you've probably read too much Hayek and it has melted your brain.

Beating a kid is obviously wrong, but parenting (and coaching and managing) does involve creating incentives to encourage desired behaviors, and discourage undesirable behaviors.
OK, fair enough. It was just prostate cancer; I might have been thinking of the likely side effect being cancer when it was really bowel damage (listed on that page). His doctor believed radiation was indeed the best option, and my mother (also a doctor) generally agreed; he didn't like the idea of the side effects. The thinking, never expressed to him, was that his severe alcoholism was likely to kill him before they developed, but they were expected to develop if that didn't happen.

Chemotherapy has extremely nasty side effects, so it's not unreasonable for radiation to be the first line of defense even when radiation is guaranteed (or near-guaranteed) to cause severe problems later on. Looking at the common side effects again, I'd take chemotherapy before infertility, but a lifetime of chronic diarrhea might well be better than going through chemo.

I also note that that page says "in general, the lifetime risk of a second cancer is highest in people treated for cancer as children or adolescents", which is definitely in harmony with the idea that radiation therapy looks better and better the less time you expect to live after getting it.

I'd be happy to unphrase my upper comment, but it seems I can't. :/
Hang on, how can they agree not to break the law for a period "5 years" instead of... never again?

If they did the usual "we are not admitting we broke the law but will settle anyway to make this go away" then the DoJ had a duty to make it clear that they did break the law.

Otherwise after 5 years some other shmuck is going to have to go after them again when they start doing it again.

It is like the DoJ just washed their hands of the whole thing. (Let the proles deal with it.)
I'm going to venture against the grain here: this is a really cool hack by LinkedIn. The OP's phishing attacks are equally cool - basically just HTML injection that leverages a vulnerability in LinkedIn's message rewriter. LinkedIn should be able to patch it relatively easily, just as they would on their website.
It seems that this same exploit would work for anyone using apple mail. Isn't Linkedin-Intro is just exploiting the fact that Apple Mail renders HTML.

Ah Ok his supposed "cluelessness" makes a little more sense now.
Seems like they're usually based on hardware emulators like qemu, bochs or similar which are compiled to javascript using tools like emscripten. IO hardware needs to be emulated in JS, a framebuffer is drawn to a canvas, mouse input events are translated to the native hardware events, I'm sure there's a million details.
I really don't understand how you can connect the dots of LinkedIn's (admittedly crappy) marketing emails and Intro existing. It seems quite simple really:

People loved Rapportive, people wanted Rapportive outside of GMail, Rapportive delivered.

> It's one of the most basic rules of growing a company that pursuing short-term gains (1-2 years) with dodgy maneuvers, directly translate into long-terms losses in the 10-fold numbers of the short term gains.
This is not too hard to understand, is the executive team of Linkedin not intelligent enough to get that?

Amazingly you've managed to crap not only on the Intro team, not only on the Intro team and LinkedIn executives, but every single LinkedIn employee – please tell me more about how to build this great culture you champion.

That's the thing, though. I didn't try it, but my guess would be that even if they patch the CSS issue, I believe it would still be possible to set the visibility to hidden (notice they never set the visibility :), and use absolute positioning to set the new content on top of the old.

Also, I saw some different results as to where the content is injected. In some cases, it was right in the middle of my content - which seemed weird. Obviously, if they aren't consistently making sure their's has the last say, then it becomes easy to override their settings.

Of course - my CSS skills are awful, so someone please feel free to correct me on that.

I believe it's actually the other way around, where HATEOAS is the least "enterprisy" of the options. When I think of enterprise or over-complication, I think of a system where logic is so deeply embedded in the server and client that if the client or server changes in any way, everything breaks. REST was designed to better handle changes between a client and server. For instance, if you built your API to use something like Collection+JSON, then it could be instantly read and understood by any Collection+JSON client (much like in the way the HAL browser works [1]). You could change things, move things, even redo URLs, and the client will still work.

If, on the other hand, you don't conform and use HATEOAS, you have to go look at the documentation on how to build the URL to make a call to the API. Your client can never explore an API, but must be built to make certain calls to certain URLs that are built a certain way.

True REST with HATEOAS was what HTTP 1.1 was built around. It may take some extra work to implement, but it was designed to make communication over the web simpler (and it's worth the trouble). Unfortunately, this article is not really endorsing what REST is, but rather a very common RPC that has been popularized by Rails and labeled as REST.

That's also because of the American Government's idiotic policies on those two "items", in my opinion.
I'm quite sorry, I didn't intend to imply that PIA is a honeypot. I use PIA every day (I'm using it now!). My point was to say that at the end of the day, we must assume the government has access to all servers and services potentially subject to National Security Letters until proven otherwise.

If the government wants to snoop on you, a VPN is one NSL away from having full access to all future use unless you hide your identity and money trail very carefully.
