Bubbles happen when everyone realizes there is a gold mine somewhere, but no one knows how to find it. Some things are overvalued, some things are undervalued. Usually the gold is in a place where you least expect it.

The Netherlands had two flower bubbles, but not because people where crazy. People started to realize that this tiny patch of soggy land would one day be the biggest exporter of flowers and vegetables in the world. Flowers are clearly worth way more per kg than grain, but how much exactly? No one knows, but surely those tulips must be worth a lot.
nowhere to go? really? last time i checked most of the earth's surface was uninhabited. why do people want to go to mars when the land can be had in the mojave desert for practically no cost? its just as dry but has an oxygen atmosphere, and there is virtually no demand for the land

or forget about the mojave. northern canada has a population per square km that is effectively zero. pretty mars-like, but you can hunt for dinner if you're smart. and once again, the land is basically free.

oh i'm not even mentioning a half dozen inhospitable places that no one occupies....why on earth would these people need to go to mars again??

Companies always say that unpaid internships are a way for people to gain experience and knowledge and build up their resume, but the way I see it, it's just a way for a company to get free work. As a former college student (recently graduated) the last thing I wanted to do was work for free during my summer when I had bills, tuition, and rent to pay.
I wonder if this is based on the search-by-image that Google Goggles (on Android) already does.
I'm not a fan of Rails myself, but I sympathize with Yehuda's position. The helpers are my #1 gripe with Rails. It really kills productivity to have to dig through all your views for what feels like pet changes.

The one point Yehuda's making I'd dispute is the impact of Arel.

I saw a very early version of Arel back when I was maintaining DataMapper. To be clear, Arel is beautiful code. It's ridiculously well done IMO from an OO stand-point. It's the code I wished I could write in DM.

I didn't use it (or something like it) in DM because I'd been there and seen the consequences. To give the point some context, you might expect NHibernate to impose a 10% overhead on c#. NHibernate is a very complex library, doing a lot more than most (any?) Ruby O/RM. In Ruby, once you get beyond the most trivial examples, you can easily see numbers like 50% overhead, and some queries that would be a cake-walk in .NET are impractical or even impossible in Ruby with constrained resources or service timeouts.

Ruby method dispatch and object instantiation is slow. Damn slow. Ridiculously slow.

The reason DM and now AR perform two-query-eager-loads to avoid JOINs has almost nothing to do with database performance. I doubt many Rubyists really understand or grok what that means. It has everything to do with the instantiation and even simple iteration of a cartesian product in Ruby being infeasibly slow.

Getting back to Arel: It's probably the very best of Rails OO. But that it's introduced some very serious performance regressions is no surprise at all. I said as much to NK and Yehuda when we discussed it during DataMapper 0.9 development.

With Ruby you have to make compromises. Especially in such a critical-loop portion of your stack.

On the other hand, if you're going to stay with AR, then it probably needed to happen sooner or later.

Best of all worlds would have been to drop AR altogether and promote a migration to Sequel for the official Rails O/RM. ;-)
Haml is great for many cases, but it's terrible when the ratio of text to embedded code gets large. Chris Eppstein, one of the developers of Haml, made a blog post to this effect last year:

http://chriseppstein.github.com/blog/2010/02/08/haml-sucks-f...

As a result, though I love Haml, I think ERb is a more sensible default.
They may be non-malicious, but they show that someone with an intent to harm could do far worse and that most are completely unprotected.

Its better to expose problems than live with the false security that none exist. The false security leads to much worse breaches when they happen (see Sony) would be nice if Lulz hacked Sony 3 yrs ago and went public.
The linked PDF is ambiguous, "penalisation of the production and making available of tools ... for committing
the offences".

If this requires mens rea, i.e. they prove that your intent was for committing an offense, it's not such a big deal.

If it does not, i.e. your software merely could possibly be used to commit an offense, it's a huge deal.
> The difference being that there is nobody living on a planet like say, Mars.

Stop right there. You don't know that there isn't anyone living there. We've sent a couple rovers, dug down a few inches, and looked at it from telescopes. There are millions of dollars poured into the search for life on Mars every year, as there should be. But we don't know very much yet!

I am totally in favour of terraforming and colonizing Mars if we can (reasonably) prove that nothing is alive there. But we aren't anywhere near that point. The greatest crime the human race could ever commit would be the annihilation of the (perhaps only?) living ETs found, even if by "accident" as we moved in there.

Don't think that Mars is your dead playground for you to do as you wish. Treat it and its unknown past with deep respect. There's a small chance that something, somewhere, is living there, perhaps under the surface, perhaps in caves.

Don't assume we know everything about other planets just 'cause we can see them with our telescopes.
Yes, I can't see any way that could possibly go wrong.
Nah, a few scientists in the 70s believed that the Earth might cool, nothing like today. To compare both predictions and their supporting evidence is laughable.

There are several treaties on the nature of faith in rabbinic law. The case of Job is often exemplified as a case of "true" faith as opposed to faith not for faith sake.

The true faith, does not seek reward for good behavior, nor bothers trying to understand the divine will, it simply accepts the Yoke of the heavens. in the case of Job.

He does not ponder the reason, it is all the same to him "...the Lord gave, and the Lord hath taken away..."
(When) Will The MacBook Air Get a Touchscreen?
While the resolution of the webcam is (obviously) important when discerning accuracy, I feel like you may be conflating two terms here. Specifically, going from the resolution of the webcam to an estimate of so many pixels of accuracy using basic trigonometry will necessarily depend on the method you're using to convert the webcam input into eye-tracking data.

The <70 pixel figure for GazeHawk's accuracy is based on testing against real, labeled training data. That is the distance, on the screen, by which our calculated gazepoint differs from the true location at which the user's gaze was directed. It is only loosely correlated with webcam resolution, in that a higher webcam resolution corresponds to a larger pipeline - more input pixels being dumped into the eye tracking algorithm. I could be wrong, but it sounds like you're discussing the size of the eyes in the input image.

Also, at this point a discussion of accuracy vs. precision becomes germane. The use of higher resolution video as an input can often impact one but not the other.
Can't find the data for the valley but I imagine it would be in the $1500-$2000 range.

Someone who has never been sick without parents to care for him might not notice, but once one has the experience, one can appreciate it and pay the debt back (or forward).

wrong. that bottle of organic shampoo from whole food commits about 98% of the sins as a bottle of a nonorganic varity from safeway. both are put in plastic which may or may not be recycled but was certainly made from oil (like all plastics), and was driven to the store in a vehicle that emits CO2, stored in a room kept warm or cool with a device that emits CO2, and then driven back to your house in another vehicle that emits CO2, where it is stored in your closet kept warm or cool by another CO2-emitting device.

and in the end its a toss-up if it even gets recycled, even after you put it in the blue bin. but that process also emits CO2
Yes but all of that was after you had gone through most of the weed out boring stuff (at least that was how it was further back than I care to admit). You really had to be committed to it to stick around to get to the fun stuff. But, I think what Matt is really saying is maybe CS is backwards. We could boost people's interest in doing the fun stuff up front and then layer on the foundational underpinning once they've got your attention. I bet if people are really excited about doing what he's saying they might be more inclined to stick around for the really hard stuff. But, even if they don't there is merit and growth that happens in learning the practical or, as academia might see it, mundane things.
Not running, treadmill on cardio with high elevation and at 4.5mph. When I feel like it I manually chnage the settings for 5-10 minutes so the body is not used to it. I read that the body,, being a perfect machine tries to do the work with the least amount of energy wasted so you have to trick it. We can go to McDs now, no need to hunt in Africa for a week hoping to catch something :)

Running for 45 minutes might not be good for your knees (I think)
An immediate expiry would not solve the initial problem. A user can easily click on the link on an iPhone, then want to read the content on his desktop. A timed expiry would work much better.
This idea, like the other comments said, has been beaten to death so much I am not sure why its still a discussion. I mean its common sense that the idea is less important than the execution. If we created companies off ideas alone we would have flying cars or time travel. Obviously this is an exaggeration and on the far end but its true. Every idea is a branch of something else, every idea is a combination of two other ideas. Every idea that you come up with may not be unique but what the idea actually indicates, and this is something Paul Graham said himself is the idea is a sign of the entrepreneurs intelligence. I believe thats true the idea should be viewed just as that, a sign of the thought process and the way they look at the work because I myself know that the initial idea I create is not the idea that I have three days from now. Idea's constantly evolve just organically in life and with different interactions you have which give way to even better ideas. The idea is not what wins its the ability to have a coherent and good idea and continue evolving with it. "Your idea is not special" is true because we as humans are for the most part not original creatures and our inspiration comes from other things but what is special is the way you continue to evolve the idea and how you take new ideas that you have and meld them into your original idea. Pandora is a great example, they did not start out as a internet radio company but as the music genome project and overtime changed focus to what they are today.
> binary tree is balanced and that each node is one character

I found that pretty intuitive given they tell us it is a tree with 2^n-1 nodes, and that this is then umber of characters in the text file.

What I'm wondering about is what the '=' pad character means in the context of non-valid base64 (i.e. isn't it the same as the 'A' character - a null?)
So we will either die of cold or heat. Maybe.

Some more sensational coverage in The Register [1]. The correlation between low sunspot activity and the 'mini ice-age' is well documented, its not proven that solar activity caused that ice age, but it looks like we are getting a chance to run the experiment again.

I'm continuing to follow are reports from the STEREO mission [2]. After reading this paper [3] on the correlation between geomagnetic activity on the sun and terrestrial temperatures.

>Personally I am holding out for the pill that will give the same effects to my body as exercise does (it is all just chemicals, anyway).

Some of those chemical reactions likely depend on the fluid dynamics of heavy exercise -- lots of blood flow (I'd almost call this a given) and tension in muscle tissue.
That's odd since the evidence we have so far points to humanity adapting our environment and improving our living conditions with breathtaking success.
Actually AT&T attaches a data plan to your phone if they detect it to be a smartphone. This is even if you go and switch Cellular data to Off in settings.

They were able to do that since they had database of IMIE for iPhones. So if they didn't have the IMIE info (say unlocked phone bought from retail channels), they didn't do so.

It'll be interesting to see if they can detect these new unlocked iPhones.
Thats only half the reason for the lack of mods, the other is that the orignal game creation sdks are now free or freemium atleast so it wouldn't make sense to try to mod something if you can get supreme tools for original creation nearly for free.
“Oh Wow” Moments in Technology
The evidences are not being compared by themselves but rather used to lead to the fact that "We can only do something based on what the current scientific prediction is."

Based on the current scientific prediction the best measures that we even intend to implement, The Kyoto Protocol (for all it's economic constraints), is by far pushing the effects at most by a decade. Would it not be a good idea rather to start looking at living at higher temperatures?
The problem is that without the other life there can be no human life. We are on the top of the food chain and as such we depend on all other animals for our survival. Hopefully it makes sense what I'm saying.

Wow! This is the first I've heard that RoR's ORM is slow. That's it's slow because Ruby is slow, is even more of a shocker.

I'd love to hear some practical limitations that applications using Ruby and NHibernate face when querying data.

Is this slowness a reason that so many no-sql engines seemed to have sprung at the same time as RoR?

Ask HN: Googlers... What apartment complexes house them in Mountain View?
I'm moving from Santa Clara to Mountain View itself by the 1st of the month. I'm determined to meet more Googlers for business networking reasons. I also may soon be a Noogler. My budget maximum is about $2000/month for rent. So what apartment complexes contain all the Googlers?

I'm ready to move immediately. Mention a specific complex where you live and you can earn a move-in bonus if I rent there.
I never say that as it doesn't seem right to me. What good reason could God have for the loss of a good man or child that is without sin?

If you're a Christian however, you do have a small comfort that death may only be the beginning. And that's really what Christians should hear - that the loved one is in a better place.

And yes I know, that sucks too as how could you really know that she's in a better place? But I experienced this myself and it sticks in the back of your subconscious, eventually giving you comfort.
Minecraft is still up for me... is a short-lived DDoS news?
I understand your sentiment, but imagine the process of choosing a very risky treatment. You sign a form saying "For reals, I know this may kill me, but I'm not going to sue you unless you do something crazy like jam a fork in my head during the procedure."

That should be enough, right?

But it's not. Because if things really do go badly, many patients in our sue-happy country will say "well I knew it was risky, but I didn't know HOW risky!" And the patient may win the suit - maybe justifiably, maybe not. But doctors know this and will be cautious. So that's one contraint on you getting to try whatever you want.

Secondly, say things go badly and the patient is horribly hurt but not killed. Now he/she needs expensive medical treatment every day. Is the government going to pay for that? Surely your waiver can't also waive Medicare? So the government (meaning me and my tax dollars) also have some interest in not letting you undergo any procedure you want.

If you could really, truly waive all your rights to recourse and help, maybe you could get any procedure you want. But if you could do that, wouldn't you be pressured to do so when you didn't want to?
I do believe my point was that no law is free of unintended consequences, particularly not your law that outlaws laws with unintended consequences, thus your law outlaws itself.

The outlawing of the law against laws with unintended consequences by the law against laws with unintended consequences would undoubtedly be considered yet another unintended consequence of the law against laws with unintended consequences.
Solar Bikini
Let's say we could kick it down the road 50 years--I don't believe a mini-Ice Age is coming either, and even if it is NASA for one expects it to counteract only around seven years of carbon emissions. So this is all a bunch of pointless hypotheticals. But bear with me.

50 years from now, assuming around 2% annual global growth (a conservative guess), the world will be over two and a half times richer than it is now. We'll have had 50 years of technological advancement. Given that right now the biggest roadblocks to dealing with climate change are (a) the very real costs of mitigation and (b) the lack of technological ability to cost effectively generate carbon-free energy and remove CO2 from the atmosphere, there's a decent case on the face of it that we'd be more able to deal with it, notwithstanding the couple hundred extra ppm of CO2 we'd have to worry about.

Part of my motivation is also that I'm increasingly pessimistic about us getting our shit in order in the present day. The current radically corporatist administration in the USA gives only lip service to the problem, and the opposition... well, the less said about the opposition, the better. So if the hand we're dealt is that we have to deal with climate change in the present, we're pretty much fucked. Kicking it down the road would at least offer some hope.
I'm the author of the PragProg book on CoffeeScript: http://pragprog.com/titles/tbcoffee/coffeescript

This is an excellent (and free) crash course on the language that anyone interested in learning it should check out, especially if they already have a solid JavaScript background. I like the approach of clicking the code examples to toggle between CoffeeScript and JS code.

Basically, if you already love JavaScript and want to know what all the fuss is about, The Little Book on CoffeeScript is perfect for you. If there are gaps in your JS knowledge (e.g. you're not sure what `this` is or how prototypes work), or you want to learn more about jQuery and Node.js from a CoffeeScript angle, then you should check out the Relatively Big Book on CoffeeScript published by PragProg. :)
I like the idea, but I'm concerned about paying up front for a style-based product that I haven't seen yet. For example, this kind of thing has been done successfully with wine, but I'm fairly certain I'll like the wine no matter what they send. I can't say the same about a t-shirt. Personally, I don't know how you're going to convince me that I will like the shirt you send when I don't get to see it until I get it.
After reading the article and comments, it appears that what this really represents is a need for more secure email protocols. How would one go about creating and ensuring and end-to-end secure email protocol? It could be done within a domain, but once you send or receive messages outside of your domain it's up to the intermediate and end parties to keep the message secure.

I suppose you could ensure secure communications via encrypted messages and end-clients with the key, but how could such a system be ubiquitous and practical?

A) Because every dollar invested in the US space program since inception has created about $7 of economic benefit to the consumer economy.

B) (Related to A but worth mentioning separately:) Because the space program has led to major advances in medicine that have improved length and quality of life on Earth. [1]

C) To gain access to essentially limitless energy resources via space-based solar.

D) To gain access to material resources (e.g. minerals) that are scare or absent on Earth. [2]

E) To create an off-Earth breeding population of humans so that one asteroid / plague / nuclear war / whatever cannot wipe out the entire species.

[1] Here's a simple example: When the Hubble telescope was initially launched, it had a small lens defect that blurred the pictures slightly (the pictures were still better than any Earth-based 'scope, though). Image processing software was developed to clean up the pictures until a replacement lens could be deployed. That software then migrated over to MRI machines where it is now used to detect tumors much earlier than used to be possible.

[2] These resources are better accessed from the asteroids than Mars, but going to the latter gives you access to the former.
