oostevo··on Iranian Hackers Post Images Over JFK Airport From UAV That Was Hijacked In March
My Arabic is pretty terrible, so the third part didn't make much sense at all, but I copied it as: بكم فتح الله و بكم يختم و بكم ينزل الغيث و بكم يمسك السماء ان تقع على الارض الا باذنه و بكم ينفس الهم و يكشف الضر

Maybe someone else who speaks the language or someone who wants to try with Google Translate could help out.

oostevo··on So You Wanna Build a Crowdfunding Site
It's worth noting that Startup Engineering is basing its payment platform on Bitcoin whereas this Mozilla article covers Balanced Payments.

I also get the impression from the lectures so far that Startup Engineering isn't covering databases to any real extent, whereas the article covers MongoDB.

oostevo··on "Cruises were priced similarly to assisted living centers and more efficacious"
I had a small injury -- just a broken bone in my hand -- on a cruise ship about ten years ago.

There was a doctor and two nurses on duty at the time. The doctor had to be quite resourceful: he checked my vitals, took, developed, and interpreted the x-ray, and then set the broken bone. I gather the doctor(s) onboard also wind up serving as the primary care physician for all of the staff on board, too.

The facilities themselves were quite sparse, and with somewhat dated but still functional equipment. The x-ray used film, after all. He also wound up using a spoon from the dining room as a splint, because the ship didn't seem to stock small splints.

My understanding is that shipboard medicine has advanced considerably since then. Some cursory Googling suggested that ships are routinely equipped with satellite connections to doctors on shore, ecgs, defibrillators, and the like.

oostevo··on State Department Demands 3-D Gun Blueprints Be Removed
I'm nothing close to a lawyer, but I bet the people you linked to would indeed get in trouble if they started shipping their parts overseas.

The law (ITAR[1] and the Arms Control Export Act[2]) wasn't designed to keep home-milled ArmaLite parts out of the hands of US citizens. The goal was to prevent someone like Lockheed from doing something like selling stealth fighters to an adversary without checking in with someone first. It's basically written as banning the export of military technology to foreign countries without the proper paperwork.

Apparently, to the folks at the State Department, stuff like PGP[3] and plans for a 3D-printable gun count as "military technology" and putting it on the internet counts as "export". That's pretty different from the ATF deciding that a lower receiver without holes in it doesn't need a firearms dealer for a transfer.

oostevo··on Save Your Kisses For Me
I get that our propensity for wishful thinking made it easy to underestimate the post-revolution popularity of Islamists, but their rise shouldn't have been that much of a surprise.

In Egypt at least, the Muslim Brotherhood had a number of pretty significant advantages compared to liberals and secularists. Whereas Mubarak basically crushed secularist dissent, he seemed to tolerate the Muslim Brotherhood (on a very short leash) for use as boogeymen. They were also able to organize in mosques, which were more or less untouchable, whereas nobody else had such a safe place to organize. Finally, the Mubarak regime was largely secularist, which tainted other liberals by association.

The end result was that, after the revolution, the Muslim Brotherhood had a very well-organized political network ready to go, while everyone else was going, "Hmm ... time to form a political party. How do we do that?"

Some hotels do something similar -- chains sell the mattresses that they use in their hotels to consumers.[1]

oostevo··on Anonymous allegedly hacked Romney tax records
Not really, per Bruce Hoffman (a Georgetown University professor that's an authority on the subject)

"Terrorism is ... violence - or, equally important, the threat of violence - used and directed in pursuit of, or in service of, a political aim."[1]

Certainly this is political, but I think it's a stretch to call releasing stolen tax returns violence.

oostevo··on CWI cryptanalist discovers new cryptographic attack in Flame spy malware
"Not only is the US infrastructure not ready, but it looks like no one is actively trying to change that."

Really? I know it's controversial, but that's pretty much what CISPA is supposed to help with.

oostevo··on US Government tries to restrict publication of details on avian flu virus
There are some places where ITAR makes sense, even if it does overreach in areas like encryption or model rocketry.

For example, I'd argue that it's a positive thing that Lockheed couldn't sell F-22s to [insert violent autocrat of the month] without some very significant reviews.

oostevo··on Mythbusters experiment goes awry, sends cannonball through two houses
Private intelligence?[1] They tend to put a much larger emphasis on delivering good information over writing an engaging story. They do focus almost entirely on geopolitical news, though.

Stratfor and KGS both offer free access to a limited set of their analysis.[2,3]

oostevo··on Standing desks are on the rise
I've only seen a few models of surveying tripods, but the ones that I did see didn't have locking legs. Their stability comes from points on the bottom of the tripod legs which you drive into the ground when setting up the tripod. I'd imagine driving three stakes into your floor at home wouldn't be optimal for you.

You could probably find a used astronomy tripod (used to hold a large telescope and then position it precisely) that's out of spec for astronomy use but that would hold your laptop just fine.

oostevo··on IMF: The Age of America About to End
"...because the US government is believed to be highly unlikely to default."

And that belief stems largely from the status of the US as the sole superpower (at least for now). That's the point I was trying to make. I just didn't do a very good job of it.

I probably should have just picked an example of the US exercising diplomatic power, because that's much more intuitive to me than currency markets are.

(Thanks for patiently correcting me, by the way.)

oostevo··on IMF: The Age of America About to End
Well, I was thinking of relatively expensive on the scale required for country-scale commodity purchasing, but that may not be right either.

Since I gather you probably know more about monetary policy than I do, how's this logic for an explanation of the benefit of reserve currency status?

* Things (like oil) on global markets are traded in USD.

* That means countries need to accumulate or exchange for USD in order to buy things.

* This both increases the value of the USD and means the US Government can issue bonds at lower rates than they otherwise could.

oostevo··on IMF: The Age of America About to End
There are _huge_ economic, cultural, and military benefits to being the sole superpower that don't exist for country number two.

These benefits are, in essence, virtuous cycles that give the superpower a advantages on the world stage just by virtue of already being in first place. Think of it like compound interest, or a really big ball in Katamari Damacy, only for geopolitical power. That is, the US can arrange things in its favor to make it more powerful just because it's already quite powerful and no other country is.

As an example, the United States Dollar is the de-facto reserve currency for the rest of the world. That means that the US can purchase things without having to first go through (expensive) currency exchange, giving the US an economic advantage. The reserve currency status is also a major factor that also allows the US to borrow money pretty much at will.

Similar arguments can be made about cultural, military, diplomatic, and other power.

That means that countries aspiring to be the superpower have the deck stacked against them. So when, despite this, China overtakes the US, the US will have an awful lot of catching up to do. It's not fighting for food in the streets, but it would be a fairly serious blow to the US.

oostevo··on Show HN: My "semester" project: cab sharing made easy
I'll second the call to hear who the designer is, if you don't mind sharing.

Actually... could you outline your process of finding the designer? What was the workflow like? Did you send him your .nib files and let him go to town, or did you send him screenshots, or what?

oostevo··on Libraries in C++ for ACM
Somebody correct me if I'm wrong, but as far as I can remember from when I was doing ICPC, I wasn't allowed to bring in anything in electronic format. I could, however, bring in printed materials.

Have the rules changed? Or are these libraries just for practice problems?

oostevo··on Everything You Know About Fitness is a Lie
I don't think the two are _necessarily_ contradictory.

The article says, essentially, that a basic strength and conditioning program is the way to go. The GP says that picking a sport that makes you fit is the way.

To add another opinion, that ties the two together, to the mix: think of the fittest people you know. To a person, they're probably obsessed with their chosen sport (which may be soccer, or bodybuilding, or weightlifting, or running, or ...). These people live and breathe their sport, and when they're not doing it or training for it, they're thinking of how to get better at it.

At some point, thinking of how they can get better at it is probably going to lead them to doing, well, a basic strength and conditioning program. That's because squats and presses and the rest of what the article outlines are still about the best the exercise world can come up with for almost all the athletes out there.

(For what it's worth, I'd strongly second the recommendations of the article for Starting Strength and Olympic-Style Weightlifting. They're both fantastic books.)

oostevo··on Optimal Employment
That's really surprising on the health care front. I think many westerners (myself included) think of Japan as a paragon of efficiency and effectiveness in nearly everything.

Can you elaborate on what's wrong with the system?

oostevo··on ACM considered harmful
That wasn't true when I competed. I actually picked up a complimentary membership because I competed, if I remember correctly.

My institution was ACM-affiliated, but I'm not sure that matters either.

oostevo··on How I Blew Out My Knee and Came Back to Win a National Championship
Along the lines of blown out knees in gymnastics is the incredibly inspiring story of Shun Fujimoto, who injured himself during a gymnastics routine in the Olympics, and then kept competing.[1] Per the Wikipedia article on the guy, "One doctor stated: 'How he managed to do somersaults and twists and land without collapsing in screams is beyond my comprehension.'"[2]

Watching that video and reading his story quickly put an end to my complaints of "but I need a nice ergonomic keyboard to be able to work at all!"

oostevo··on Why So Many Rich People Don’t Feel Very Rich
I think your mistake is in assuming that he meant a standard, FDIC-insured savings account by "in the bank." It's not terribly hard to find ~5% dividend yields in the stock market, particularly if you look outside the United States.

Further, in the US, once you have a net worth of a million dollars, you qualify as an accredited investor, opening up a plethora of new investment opportunities to you.[1]

oostevo··on The Benefits of Exercising Before Breakfast
I'm really struggling to think of a strength training scenario where your heart rate wouldn't be elevated (thus increasing blood flow). Consider a max. back squat, where all your muscles are contracting to the maximum degree that they can for several seconds. I'd say that'll make your heart pump.

(Thanks for the citations. That's awesome, and I wish more people would do it.)

oostevo··on Kaminsky's Next Hack? Colorblindness
They don't have the adjustability of the app, because they're just tinted glass or plastic, but ChromaGen already makes contact lenses that do essentially what the app does.[1]

I'm mildly colorblind myself, but I haven't tried them to see how they work. The thing is, mild forms of colorblindness really don't affect everyday life much, so I can't see a point in treating it in most cases.
