I would go even further and use the same provisioning on vagrant as on my production servers so I could set up a mini production environment with whatever dev tools are necessary with just a single command. Recently they added the ability to have multiple machines as well, so all it takes to load up a simulation of my cluster is a single command.
Just to clear up my expectations, if I were to try a similar set-up... When you are using NTFS I'm expecting that you are using virtualbox to mount the filesystem on the guest.

When you use etx3, how are you sharing the files? Like a samba share? or does the virtualbox drive mount work in the other direction, somehow?

FWIW, I do all of my virtualization on ESX, but every time one of these vagrant article comes up I'm tempted to try something local (win 8), to take advantage of the shared filesystem that most of vagrant's magic relies on (as I understand).
People are so fearful.

So, those who want to give politicians the power to redistribute our money don't like the results of economic analysis, and now they are telling people to avoid thinking like economists because economics is wrong. Fascinating.

That link is missing their evaluation of TRIPS, which they did in 2008 after they built the chips: http://www.cs.utexas.edu/~bmaher/pubs/asplos09.pdf

My impression is that TRIPS is much too complicated to be clocked at comparable frequencies to commercial processors. Their ISA also appears very hard to compile to.

I love the look and feel of the site, well done. I understand some of the frustration in the discussion about required registration but the site is still definitely worth a look. The half alive/half dead cat icon for quantum mechanics made me laugh, kudos to whoever designed it.
Just because a given surveillance/warfighting/CNO technology COULD be developed doesn't mean that one should immediately go do it.
I don't see how this is "anti-gravity" - making something that floats isn't necessarily anti-gravity. He wants to create a microversion of a weather system, so I don't see how this is going to work beyond being a few cms over the ground.
I think it'd be cool just to see how related I am to any given person I meet. I don't know how likely it is that someone would actually use this for its intended purpose though.
Those "fuel surcharges" that add up to hundreds of dollars are imposed and collected by the airlines themselves. It's just another way for them to price their tickets.

Those who pay for her services see a record of purchasing a consulting service on their credit card.

Treasury bills have a fixed-rate coupon. We pay more for older ones issued when interest rates were higher, but if we issue lots of them right now we'll still be paying 2.91% interest in 2043 when the bonds are retired. The idea is that when the economy expands further and interest rates rise, we don't borrow as much because a) revenues will be higher as well, which is good and b) it would be more expensive to borrow then, which is bad.

The Newest, High-Tech Pill Will Text When Swallowed
I can't find the article, but this isn't the first time that an airline has had a problem that grounded all of their flights. There was one in recent memory (last 20 years?) that had a bug where if there were more than 32k changes to the flights in a day it would cause a horrific crash in their system. They never hit it for so long, and then one day, boom all flights just disappeared.
That's a great point. All layers are correct, but most won't be useful for a given problem.

If you're thinking about, say, crowd reactions, then you don't want the "meatbag" model. Instead, you need a higher-level psychological model. However, if your problem is "what kind of injuries result from a bomb", then the "meatbag" model is right on.

Thinking of the body as a loose confederation of fundamental particles is fairly useless when trying to decide how much to charge for a product, but it's an excellent model when e.g. figuring out how much radiation a person will absorb from a source.

No layer denies the usefulness or reality of any of the others.

Killing a library
The RIAA thrives because most artists don't know how (or have the money) to market themselves. Without the marketing, it becomes very difficult to even make a living.

It's very similar to the reasons why a startup wants venture capital.
Because it's a mechanical failure and not an "act of God" they are responsible for any lodging/food for their passengers due to this delay... I don't know if that's a legal thing, but I do know that's how every airline I've ever flown on works.
An interesting discussion.

I'm wondering about some of the reasoning, though. For example:

> On top of all this extra power being used, we have targets to meet on reducing emissions. That means shutting down coal fired power plants, reducing our gas usage, and moving to cleaner sources such as wind, solar, wave, geothermal, and dare I say it, nuclear. How are we going to meet demand?

Are we actually trying to reduce emissions here, or just meeting someone's target for shutting down coal-fired plants? It's my understanding that a typical coal-fired plant produces around 500 megawatts. That's 12 million kWh each day. You quote a figure of 8kWh to charge an electric car. If that 8kWh is needed every day, then your coal plant gives you the ability to keep 1.5 million cars charged. If that 8kWh is not needed every day, then you get even more cars for the deal.

Now, shut down that coal-fired plant and replace 1.5 million (or more!) electric cars with fuel-burning cars. Have you reduced overall emissions? I'm not sure; but I think it is likely you haven't.

> Maybe we should all go out and buy electric cars. We will experience brownouts, electricity prices will soar, and it will be difficult. But hopefully it will start some change.

Or perhaps some of us should buy electric cars. As the number of such cars grows, electricity prices start rising. and then two things happen: (1) demand for electric cars drops, and (2) pressure from the public makes it likely that power-generation capacity increases. And then prices drop, and more people buy electric cars .... So I don't really see the need for a gloom-and-doom forecast.

In any case, as I said, an interesting piece. Please do more of them.
Yes, I suspected when I wrote that it would seem unwieldy to someone from a startup. It comes about naturally enough when you have multiple thousands of employees though.
I am surprised no one has mentioned Rule 240. I have, more than once, gone up to the agent when a flight was delayed and asked about this rule. They always hesitate at first, but if you insist, they quickly make provisions to put you on another flight.

This only works when it is the airlines fault and not an issue with weather.

Rule 240:

1) Currently file sharing focuses on consuming content, not creating it, and usually it's facilitated by people who's only objective is to profiteer from copyright infringement rather than any greater good.

2) Those companies pay royalties for the music you listen to. Some arguably insulting portion of that revenue goes or is supposed to go to the artists. When you go to TPB and view a bunch of ads and popups and shit you are only paying the site owners.
I fly the DFW to LAX route once a week and have done it on many different carriers (United, AA, and Virgin America). Even though VA offers fewer flights on this route, that has become my sole carrier (even outside of today's events). They handily beat AA on experience, and sell at the exact same ticket price (main cabin, not FC).
The thing I like about pen and paper is that I can go hang at the local coffee house or library or park, and not have to worry about wifi. Also, a guy scribbling in a book isn't as stared-unwelcomingly as a guy with a laptop.
there's a big difference between claiming that >90% debt leads to (slower) growth of 2.2% and claiming that it results in (negative) growth of -0.1%. In the first scenario, you don't grow as quickly as you'd like, in the second scenario your economy is actually shrinking and you're entering a death spiral.

Can you show me the tautology?

I don't know how to come up with a reasonable model for how people are likely to interpret words without accounting for the fact that people interpret words in large part by how they have been interpreted in the past. But I don't see how accounting for prior knowledge of word frequencies makes the model tautological.
I needed this. I have spent the past 24 hours shell-shocked.

By pure chance I was not at my usual spectator spot at the marathon yesterday for the first time in 4 years: in front of the storefront where the first bomb went off.

It's all thanks to pure happenstance: for the first time in years I am no longer a remote worker; the company that acquired my startup last fall has offices in the suburbs and I am not yet past the 6 month moratorium on taking vacation days.

The unlikely series of events that led to me not being present until about 30 minutes after the blasts is something I am still coming to terms with. I almost don't have time to...my building is still under armed lockdown because I live a mere block from the scene. I dread having to walk that route someday soon.

Still, I hate the company that acquired my startup, even if the acquisition potentially saved me grave injury. I think it's past time I quit, instead of just complaining about it and hoping for dividends.

The implication of:

That is how student financing works here in Australia: below a certain threshold income (about $37k in a country with median wages of about $50k) you pay nothing, then you pay a percentage of your income over that.
Having spent time in the military, it makes sense to me. Hurry up and wait :) I actually like that way of doing things.

Boarded a flight recently and fell asleep at once after sitting down. Woke up three hours later, plane was descending. It was supposed to be a 1.5h flight. Oh well.

There's no regulation per se, it's whatever is in the fineprint when you purchase your ticket. They typically wave any responsibility if the reason for the delay is any of the following :

bad weather, acts of God, terrorist activities, war, strikes, "any shortage of labor, fuel or facilities” and “any event not reasonably foreseen, anticipated or predicted”

This could fall under "not reasonably foreseen" or maybe act of God for the very religious :).

«Davis requested that any spectator providing media showing the attacks indicate the time they collected the data so police “don’t need to go through the electronic signature.”»

Wouldn't this be more costly and less accurate than scanning EXIF and other metadata, dumping it all into a database, and sorting and scanning through it temporally?

I'd hope that the majority of the images and videos they'll receive directly from citizens will still have this information intact.

Edit: I see that austenallred already pointed to a thread that describes such a methodology. I just find it concerning that those who are tasked with investigation seem to be ignorant (perhaps not willfully) of the other side of how technology can assist with investigations of this sort.
Is there a reason why those companies use a client-server service model rather than a p2p model?

The answer is convention over configuration. See, if we institute a societal convention that your gender is derived from your first name (automatically by a Ruby program), it will save a lot of time and energy and make the world more DRY.

I don't mean disrespect but the article is pretty empty on explaining what Category Theory is. May be it's just a prelude to a series of other articles but I didn't get that until the very end. Kind of disappointing.
Could one even be off by an order of magnitude with economic growth numbers? On a base of 2.2, that requires being off by 20%. You could never be off by an order of magnitude because economies don't grow or shrink by 20% pretty much ever.
Alaska is pretty decent also, but I usually fly in the west coast market. Southwest prices are often not that great, actually, but their service is always good.
I don't consider myself to be the average freelancer. Due to my marketing skills. Still, I will talk about the specifics you asked about.

1. I do take more than one project at a time. Usually one big (more than a month's work), and one small ( less than a month's work). I have no problem meeting deadlines.

2. Depends, and is negotiable. I will say that my rates a a hair under average for California. I do this because I work remotely and avoid flying in (but will do it if I have to).

3. I am an American doing remote work from the Caribbean.

The biggest issue freelancers have is that most don't know how to properly market themselves. They tend to think that an ad on HN will be enough to bring in high six figures (it won't). You have to have a good marketing system going on for you. After many requests from other freelancers, I'm about to offer such a system. But its has not launched yet. If you want to know more, just send me an email. The system is built around getting good leads from different boards, email marketing, and content marketing. It took me to almost broke, to , well, a very, very nice place in about 7 months. Anyhow, just email me. Others, keep posted for the launch.
You're setting up a straw man. That's not my argument. The argument is that the data bolsters the claim that more debt correlates with slower growth.
I would suggest that "using Ascii characters" rather than sprites is conflating design and implementation, and express my doubt that a 13 year old is actually thinking about ASCII, anyway. That sounds more like a translation done by someone a bit older.

Good luck.
I don't see why you say that the problem is that they run it twice. As I understand it, the problem is that they use AES with an 128-bit key, and they use it in CBC mode, which gets easily defeated once you know the last plaintext.

As I can see, they had various courses of action (don't take this to mean that they were remiss in securing their product, as they used best practices everywhere):

* Use AES-256, maybe deriving the key from a first run of the KDF and the IV from a second one, although that might also make for an attack.

* Use CTR mode. Unless I'm mistaken, the attacker would then need to guess both the key and the nonce to verify the block, which is significantly higher complexity.

* Re-encrypt the last block with the IV. This way, the attacker would have to decrypt with the other 128-bit key, and would need to know both to decrypt the last block.

* Pad the beginning, rather than the end. Or, since the string is of known length, just make it a multiple of the block size, and use no padding.

I'm really a crypto novice, though, so I might be completely mistaken. That said, it's a bit too bad that they didn't spend a bit of time thinking how they would crack their own product, they might have come up with this attack and mitigated it.

At any rate, running the KDF twice isn't a problem, unless you mean that it wastes CPU cycles for no good reason. In that case, I agree.

Why Women Should Not Run
"The Administration, however, remains concerned that the bill does not require private entities to take reasonable steps to remove irrelevant personal information when sending cybersecurity data to the government or other private sector entities. Citizens have a right to know that corporations will be held accountable -- and not granted immunity -- for failing to safeguard personal information adequately... .
The Administration supports incentivizing industry to share appropriate cybersecurity information by providing the private sector with targeted liability protections. However, the Administration is concerned about the broad scope of liability limitations in H.R. 624. Specifically, even if there is no clear intent to do harm, the law should not immunize a failure to take reasonable measures, such as the sharing of information, to prevent harm when and if the entity knows that such inaction will cause damage or otherwise injure or endanger other entities or individuals."
Yes, to attack multiple files you'd have to do multiple computations.

However, if you can try all dictionary words in 0.5 seconds, you can try that against 172800 files in a day.

Of course you'd need a security breach that gave you access to multiple files too!
