I've always liked Matlab's distinction between a function and a script. (Aye, many would call Matlab a scripting language).

Simply put, a function can map arbitrarily, and a script has the mapping and parameters provided!

At least, that's when you get into the scientific computing paradigm, as I understand it.

I think in this case it makes sense. Groupon restated a sharp drop in their reported revenues over three years.

People don't necessarily invest in things they think are particularly good business models. They invest in things that are undervalued. If you looked at the revenue/price and thought it was undervalued and then Groupon changed 3 years worth of data on your after you made a stock purchase, you'd sue too.

Just look at these reductions. They're more than just a minor correction from Groupon:

- For 2008, revenue was reduced to $5,000, from $94,000.

- For 2009, revenue was reduced to $14.54 million, from $30.47 million.

- For 2010, revenue was reduced to $312.9 million, from $713.4 million.
It's interesting- I wonder what the acceptable level of compromise is for the MintChip. As programmers our instinctive response is "none at all", but MintChip is a replacement for cash, and cash gets compromised all the time.

So, in theory, the Mint might be OK with trading off security for convenience/affordability, as long as that level is below what they currently experience with cash. It's difficult to know.
The question is how "serious" Google scholar rankings are going to be seen. In the past quite a few demonstrations have shown, that the Google scholar ranking/citation system can be gamed with relatively little effort. Let's hope that it will have more impact than those University rankings which calculate the scores based on aspects such as the inbound/outbound link ratio (as some web"metric" rankings indeed do).
Wouldn't it be easier just to lease?

The big thing your entire calculation leaves out is the time it takes to do this transaction every couple of years, because there is no way a dealership is going to give you the money you are looking for...

Not only that, but I suspect that people who are loyal to businesses and like interacting with local business owners are less likely to use sites like groupon, because they know that the businesses often get screwed, and because they don't want to be thought of as bargain-shoppers.
I've used the HUD available on the C5 Corvette, and it's no more distracting at first than any new car's radio, wiper controls, etc.

Once you've driven with it for a bit, it really does increase the attention paid to the road. Your quick checks for speed, gas, tach are instead diverted to mirror checks or just keeping your eyes on what's happening ahead.

That said, the Corvette's was a monochromatic subtle display. I'm not sure what the impact of full-color high-resolution information would be. One always has to be wary of the "ooo... let's watch the odometer rollover to the next 10,000" kind of distraction.

(Rewritten to report results)

I tried the following 4 variations in Node.js 0.6.13, V8 3.6.6.24. (The "global" business is for accessing the functions from a REPL.)

var lots = 1000000;

// A: try/catch inside loop
global.a = function () {
for (var i=0; i<lots; i++) {
try { } catch (e) { }
}
}

// B: one try/catch, inlined loop
global.b = function () {
try {
for (var i=0; i<lots; i++) { }
} catch (e) { }
}

// C: one try/catch, loop in local function
global.c = function () {
var loop = function () {
for (var i=0; i<lots; i++) { }
}
try { loop(); } catch (e) { }
}

// D: one try/catch, loop in top-level function
function loop () {
for (var i=0; i<lots; i++) { }
}
global.d = function () {
try { loop(); } catch (e) { }
}

// E: no try/catch
global.e = function () { loop(); }

global.time = function (times, fn) {
var start = new Date().getTime();
for (var i=0; i<times; i += 1) { fn(); }
return (new Date().getTime() - start) / times;
};

In the REPL:

> ({ a : time(100,a), b : time(100,b), c : time(100,c), d : time(100,d), e : time(100,e) });
{ a 7.66 b 5.29 c 5.06 d 1.45 e 1.32 }

So a million try/catches (A) is bad. But hoisting the try outside the loop (B) or putting the loop into a local function (C) doesn't do nearly as well as putting the loop in an outside function (D), which is almost as fast as no try/catch at all (E). I tried a few variations (like making the loop actually do some work) and the outcomes were all comparable.

This clarifies and confirms what ef4 said: don't put cpu-intensive code inside the same function as a try/catch. Put it somewhere else and call it. Also, local functions don't necessarily count as "somewhere else".

People don't necessarily invest in things they think are particularly good business models.

If you can't figure out the business model generating the reported millions, it's your own fault for thinking those millions are undervalued.

How many of these investors didn't actually care about the value of the stock, so long as there was somebody around tomorrow that would buy it for more?

It's trivial to figure out what encryption scheme† is being used for a cookie or HTTP parameter as long as any portion of the plaintext being encrypted is influenced by something an attacker can control directly or indirectly.

If you're not authenticating your ciphertext, you might as well not encrypt it; attackers can rewrite the plaintext, if not outright decrypt it (the adaptive chosen plaintext attacks on AES block modes all rely on messages not being authenticated).

I'd enjoy talking more about the methods to break this stuff but am concerned that HN will read that comment as "well then we just need to stop those attacks and then we're safe". I have roughly 5 years of experience on HN to back that concern up. :)

The idea sounds fantastic, but what will give the "e-dollar" any intrinsic value? 1 US dollar is basically paper with ink on it. If it's not worth anything, there's no point.
This problem is not insolvable. As you pointed out, a secure device can be built to securely transact. Or use a "bank" (but I don't like it because any centralization is against the design principle of Bitcoin).

For example, Bitcoins could be stored on a smartcard having a flexible e-paper display, flexible built-in keypad, and flexible LiPo battery [1]. Withdrawing coins from the card could require a user typing in an amount and a pin code, and then using a smartphone to scan a QR code shown on the e-paper display (or sliding the card in the merchant's payment terminal, which would scan the QR code). The QR code would represent a signed Bitcoin transaction to a pre-programmed address whose private key sits on some online server, which is only used as an intermediary step before forwarding the coins to the final merchant. The smartcard would effectively never connect to an online device during its entire life, making it un-hackable without having physical access to it. Smartcards could also be manufactured in pairs, or triplets, etc, to have clones of them in order to have redundant backups of the Bitcoins in case of a loss of one of the cards. If you know about the Bitcoin blockchain, you might ask how the smartcard can sign transactions without access to the current blockchain. Well it is mathematically possible, because a transaction just consists of ECC-signing a few bytes representing the destination addresses.

Don't discard a technology because you are unable to comprehend it enough to think of solutions to address some of its flaws. (I do agree that addressing the security of Bitcoin wallets is of utmost importance.)

Your overstating the need to secure a credit card. I could post photo's of my credit card here or hand it to a waitress, and at worst I would have to make one phone call. Yet, I can make a 5,000$ purchase without fear. Because, unlike Bitcoin I can dispute transactions after the fact yet people still accept credit cards.

Now, plug in that bit-coin wallet into a unsecured computer and within 5 seconds your account could be drained and there is no way for you to ever recover your money. Your PC and wallet might be secure, but you have literally no way of knowing that. Worse yet as soon as large numbers of people start having a few thousand $ worth of bitcoins zero day attacks are going to take on a hole new meaning.

PS: I don't do online banking or use a debit card, the entire system is horribly and fundamentally insecure. But, I only need to pay off my CC every month and suddenly I have near total safety. Or, I can walk up to any ATM and suddenly have total anonymity at the cost of some risk.

However, the evidence against the 1 crash per 100k miles case where the car is no longer comparable to human error rates is at least suggestive. And the evidence against the 1 crash per 20k miles case is actually pretty decent. I chose my words carefully.

I loved the video, but it didn't show the glasses on his face. Besides the technical/usability challenges, I think the cultural connotation of the device will be an equally deal/no-deal situation.

Like the Segway, significant portions of the society might associate negative connotations with the device ("dorky", antisocial, pretentious etc).

I remember when a friend bought a pair of Oakley sunglasses with built in headphones. I think amongst my friends, the almost unanimous consensus was that it was not a good social statement to say the least.

The first world you should test it on is one in which someone's built a control panel/interface for the CPU.
Related to all of the people who've already sunk a bunch of work in to this; the official lore/backstory says that the whole premise was instigated by a Big/Little Endian mixup, and that the DCPU is supposed to be Little Endian...

But from Notch's spec document:

"Instructions are 1-3 words long and are fully defined by the first word.
In a basic instruction, the lower four bits of the first word of the instruction are the opcode,
and the remaining twelve bits are split into two six bit values, called a and b.
a is always handled by the processor before b, and is the lower six bits.
In bits (with the least significant being last), a basic instruction has the format: bbbbbbaaaaaaoooo"

In other words, the current DCPU spec is Big Endian. So I wonder if Notch will be rewriting the spec, even though from all accounts it seems that he's already implemented the emulator.
