I guess when I say "what's the point?" I mean, what's the point of really wasting so much time and effort getting Ruby running on .NET in general? And I say that as primarily an MS developer. It's all just a plot to sell expensive licenses and thus will never have good community backing. Look what this guy went through. He's talented. It's a shame he didn't work for a company like Google who embraces OSS more genuinely.

Things must have changed since the 80's and are probably based on particular market segments/disciplines. Back then, science/engineering pay grades were below private industry - the stability of govt. made up for it. I've got no clue now, but I can't see how, for example, govt. pays more than pharma.
That first paragraph resonated with me as well. I've been using lisp for just a few months, so I'm hardly the grizzled lisp veteran of stereotype. And yet when I bring up lisp and you-the-person-across-from-me-who-seemed-so-smart-until-now say parentheses are hard to read, I find it's easy to sympathize with lispers. The language has lots wrong with it, no question. But if you're pretending to be knowledgeable about the subject and your critique of lisp includes 'parentheses', you're a moron.

If the weapons are truly smart, who has any use for an omni-directional blast like a grenade? Keeping with the ball form, it is more likely it would hop and shoot tiny bullets into the forehead of everyone in the room; it could use the same exact tech that cameras now use to auto-focus on faces (until everyone started wearing decoy faces, ala numerous examples in the animal kingdom).

One "Little Boy"'s tonnage worth of gun-toting quadricopters dropped on a busy city would probably result in more deaths than Little Boy itself did.

ahh, just noticed a problem for me - I've transitioned to using Spotify instead of iTunes... Service sounds intriguing though - i would recommend integration with Last.FM for scrobblers.

Also, there are tons of 3rd party scrobblers for Mac. iScrobbler is pretty decent.

I don't meant to sound negative. I think Last.FM has sewn up the "data" space (eg: what I'm playing, top artists) - but it sucks for recommendations, social, and everything else.

It isn't clear to me how your service is different to Last.FM in terms of setup. EG: I'm not a Last.FM user ... am I going to use your service, instead? Saying only 2 of my friends use x service so I made a competitor for them to use seems like mildly false logic. In these spaces I'd like to see something that works around the barrier to entry (requiring a scrobbler of some sort)

I agree that in some cases, guards, defaults and ternaries flow more naturally.
However, I feel that there's a contradiction. You say that it is easier to understand but have learned to write them in plain old "if" first because it's better. It's easier to get it wrong if you write it shorthand.
If it's better to start writing them in "if", doesn't that mean it's easier to understand? If it is easier to use guards, defaults, and ternaries, you shouldn't have to resort to plain "if" to get the logic right.
And I agree, DOCUMENT!
just a random data point, but I'd recommend either ignoring bkudria (no offence!) or going full hog on a solution - in my experience people are black or white about social recommendations, and it isn't worth spending the resources to convert the people to the service. Focus on people that want it.

I have never found the fidelity of online learning to be _anywhere_ in the ball park of in-institution learning.

Especially in the areas of humanities and so forth, but also in Engineering (I hold a BSCEng, and am currently a Masters student) labs, conversation, community learning are all essential.

I also can't help but think of the Socratic method, and how at least I personally tend to learn in that manner. Simply being presented with information as fact doesn't really do it for me. Being guided, and assisted at coming to the truth on my own always leaves me with a much deeper connection to the knowledge I've acquired. And I feel that requires as certain measure of realtime interaction with someone who is an expert in the field. Simply watching their lectures while informative, does not seem to be enough.

While this may change in the future, given that online learning is in its infancy, I think 5 years is a bit short term. Especially considering the pace at which the established institution of education moves.

If you don't know some basics, you can get in trouble.

But if you do and if you get particularly clever, you can get in trouble on the next generation of whatever you're designing for.

TANSTAAFL.

With some of that C code shown, I'd try a "static inline" on the declaration, and see how well the C compiler and its code generator dealt with it. (If I can get out of dealing with it and cede the work to the compiler, all the better...)

And the caching locality discussions are the same ones that arise with virtual memory out in main memory; if you bounce around all over the place in address space (eg: setting up the wrong stride on an array, or partitioning your data differently from your access), you'll incur page faults.

And if you get particularly good with your packing of your data, you can sometimes trigger word tearing when you're accessing adjacent data within the same granule from different processes or different threads.

Caches and cache designs, too, are individually funky. There are processors which got faster by going to smaller and fewer caches and better (lower) latency. So if you fell out of cache in the new design, you'd assume you'd do worse, but with lower latency on the box out to memory, you actually did better pulling from main memory than if you were pulling from second-level on the previous generation.

Short version: Good quality sea salt makes a huge difference. Good quality fats make a huge difference. Addressing PH balance does miraculous things (people with CF tend to be way too acid and this likely is part of what causes the "normal progression of CF" because high acidity within cells causes proteins to miss-fold and a miss-folded protein is the crux of the matter in CF).
That IS the point of the article though. The past few booms were WallSt./FED-inflated anyway. Combine the concept of public service / public property (ie ill-defined or merely formal/shortterm-administrative rather than heart-felt/longterm-invested ownership responsibilities) with easy credit and decades of cultivating debt as a life-style choice and this is what the return trip looks like.

check out Spotify if you can, they've made sharing tracks super easy - but suck at the Last.FM bits.

As a music junkie I use a few services:

Last.FM for the data (on me & friends (but not Facebook friends...))

Spotify for playback and sharing songs to friends (but not Last.FM friends - Facebook friends)

Hype Machine for hot music recently (scrobbled to Last.FM)

The huge weak spot is recommendations. Where do I go for artists like Eminem? I currently use the Spotify related artists page, boy does it suck.

Actually, I also use What.CD for music recommendations..

This is what What.CD suggests for Eminem: http://grab.by/5MLs

and this is what Spotify suggests for Eminem: http://grab.by/5MLu

Neither brilliant, honestly.

So yes - recommendations - valuable. Powered by my friends, what's hot, and algo for similar. Make a Pandora Radio minus the Radio bit, sounds useful. Maybe a weekly digest of similar artists I'll enjoy based on what I listened to this week.

I like Raymond Smullyan's version even better, it removes all probability issues and is so simple you feel it must be easy to figure out.

The setup is the same: two envelopes, once with twice as much money as the other, you pick one and before you open you are offered to switch. If you do switch you might either win money or lose money relative to what was in the envelope you chose first. Let's compare the possible gain to the possible loss (without worrying about the probability of having a gain or a loss):

1. The possible gain is equal to the possible loss.

Proof: The two envelopes contain x and 2x, so you'd gain x if switching from x to 2x, and you'd lose x if switching from 2x to x. The possible gain and the possible loss are both equal to x.

2. The possible win is larger than the possible loss.

Proof: Say the envelope you chose first has y. Then the other envelope has either y/2 or 2y. So if you gain money by switching you gain 2y - y = y, but if you lose in the switch, you lose y - y/2 = y/2. Clearly y > y/2.

This version kept up at night for days when I first read it. I never figured it out --not that I had any chance of doing so, given that Smullyan couldn't figure it out either--, I just got used to not understanding it...

I think it's pretty easy to miss Gates' point.

He said that you'll be able to find the best *lectures in the world which will be better than any single University. With initiatives like MIT OpenCourseWare and iTunes U, this isn't that hard to imagine.

I think most HN readers wouldn't doubt the power of a motivated, passionate individual when it comes to learning.

To me, the takeaway point that is most interesting is Gates' desire to break down the barriers to higher education and the transfer of knowledge. He also recognizes the declining value of a Bachelor's Degree.

Educational Institutions will always be vital to the education of "tomorrow's leaders," but the current paradigm is flawed and I like where Gates seems to be going with this.
The Research-Practice Gap
Let's say you open the envelope. And there's $20. That means the set of two envelopes is either $20 and $10 or $20 and $40. In one case, the amount of money in play is $30, in the other, $60.

Now, you have no idea which it is. And the fact that you're holding a $20 doesn't tell you anything.

The $20 is fake information. It hasn't revealed any real info, as you knew you'd open something. The key is not to combine a world where the total envelope value is $30 and where the total envelope value is $60 which is what happens if you add up probabilities.

Instead, there's a 50% chance you're holding 1/3 of the total value, 50% chance you are holding 2/3. So if you switch, half the time, you add 1/3, half the time, you lose 1/3. net expected gain from switching: 0.

You should analyze your statements against what the article said. Oh, and also reality.

Edit: But it is brilliant that this comment would be by someone named CapitalistCartr, what with the class war looming and right v left being an anxious distraction. I can't see how anything other than copious amounts of fear will keep the class war staved off--xenophobia, war, and culture changes surrounding the religious do the job nicely though. Pretty easy to summarize the sources of power.

I don't have much expectation that people will feel played, so looming but maybe not likely. Fox is famous for Fox New at the same time as Family Guy, The Simpsons, and American Dad, and hardly anybody pauses at that; quite a prominent mix of Right v Left right there by an ideologue like Rupert Murdoch.

It's worth mentioning that they're writing for DSP systems. More mainstream CPUs have a larger instruction cache (and smarter eviction policies), but the size of the hot code paths are (I imagine; I'm not terribly familiar with DSP) likely not much bigger, so that the problems they mention need solving less frequently for typical applications.

The original article is about budget problems at state and local levels, so salaries of federal employees aren't really relevant. Aside: the Heritage study gives a premium of 22% when controlling for education level; the authors have not controlled for experience level and have no way of controlling for intangible skill differences which might legitimize the discrepancy.

State and local employees make less then private sector employees (on average) when controlling for education, experience, and so on[1]. This is not to say that each and every municipality has been managing its budgets well; clearly many haven't, and outlying salaries seem to be part the problem[2] in specific situations.

I think artist recommendations is a different beast from user recommendations. Recommending similar users is something relatively easy and the main roadblock right now is there not being enough users.

But if I go into artist recommendations (as opposed to general new song recommendation and recommending other users), I'd take the same approach and do something much more dynamic than a fixed list of similar artists. So perhaps taking the subset of users who like Eminem A LOT and taking their top tracks under the same genre, merging them (as if you followed them), and providing that as a list of similar trending artists.
The real big one would be the wars in Iraq and Afghanistan, which the article does highlight. That's order of $1000B.

Accidental downmod. Excellent comment.
It's a combination of two things: An extended musing on the nature of Godel's Incompleteness theorem, including its practical and philosophical consequences, and a series of things as jacoblyles explains in his comment.

It's an arty/fun book, I don't think it's bad, but the "mystery" you perceive at the heart of it is simply Godel's theorem, which, to be fair, like many other aspects of computer science does indeed have more application than the immediate, raw application of the proof. I suggest spending some time with one of the more formal explanations of Godel's theorem, one that is really careful to explain how the self-referential statement is really constructed.

This doesn't eliminate probability, and it's really the same flaw, just with different wording. The flaw is still that the variable is undefined (or infinite probability) in one part of the word problem, but treated as defined in another. So, start with when you first chose the envelope which has y. At this point "y" is undefined, and can be the higher or lower amount. That's the key. Yet, you then continue to propose that by switching you gain 2y - y = y. That equation is not okay, because "y" could have been the higher amount, and the equation breaks down. Once you assert the equation holds true, you have thus defined the original value of "y" from that first envelope choice (i.e. "y" was lower). The same flaw surfaces by asserting your switch to lose equation is true, as well.

Edit: BTW, the reason #1 works okay is because you define upfront the variable value ("x") as being either the higher or lower of the two possibilities, before constructing your equation(s).

This is what deflation looks like - very bad for any person, business, or government in debt. Quantity and velocity of money decreases, leaving less revenue to service and pay down debts, forcing cuts and austerity across the board.

This is what Bernanke is trying desperately to prevent, even at the cost of devaluing the currency by overprinting. Whether it will succeed is arguable, depending on whether the idea of Diminishing Marginal Productivity of Debt is accurate and applicable:

So is this Kanye "sampling" Conan?
Not so. The only stipulation was that you must be able to guess a number in any range (which is not possible in practice). It doesn't matter that the probability of picking any particular number will be 0, as long as the probability of picking any one between the two in the letters isn't 0. Any time your guess hits the correct range, you win. Any other time, it depends on whether you got the big envelope or the small one.

So knowing just one endpoint of a range is, oddly, evidence as to which way the other endpoint lies - as long as it might be either one. You just take a guess that depends on the number you know in such a way that the smaller the number you see, the more likely you are to guess it's the smaller of the two, but are never certain. Presto, guaranteed you'll get more than 50% right, as long as you get fed both the small and the large envelopes in equal proportion.

If you can't be sure the other guy is playing fair and might favor giving you the low envelope, you need to look at something like the Monty Hall problem.

I can't think of a case where lazy evaluation would be required, only that the semantics of the && and || operators not change.

It's defined as part of the language that && will not evaluate the right hand side unless the left hand side is truthy. A lot more than using this stuff as branching would break if some implementation arbitrarily decided to not follow that anymore.
What's sad is that the US could really afford these things. It's just a matter of seriously misplaced priorities.
