It seems hard to believe that in only 10 years, people would have forgotten the last bubble and buy right into the next one.

If there's a bubble in tech, I don't think it can really be that big, because to some extent it requires a public lack of awareness and caution with respect to bubbles.

>I hate it when some "authority" tries to prevent me from doing something "for my own safety" - NO, instead, tell me what the risks are, and how can I prepare myself to deal with them, and then let me use my own intelligent mind to make the final decision.

My problem with this approach is that I predict that many who would join you in these decisions are going to lose out. However, you all still retain the right to vote in the future for forms of restitution to be made to you by the government.

So Wall Street gets richer, some of you do well, and I'm at risk of helping support those of you who don't.

Find a way to guarantee that I won't be your insurance policy, then I'll more fully support your right to take risks.
Yes, but think printing or other media where Javascript isn't allowed to run at all.
>Betting on sunspots to reverse a century of adding carbon to the atmosphere via fossil fuels is a bit of a long shot bet.

Based on what? A single sunspot may be many times the size of the earth. There is no question that if the sun "wanted to" it could do drastic things to our climate, dwarfing any mechanism on the earth, man-made or no. Predicting sun spot activity is on the same level of difficulty as predicting the climate, after all: chaotic systems.

I don't question your overal premise; carbon-based global warming isn't going to just "go away." I'm also in favor of embracing 'disruptive' technologies.

But your language comparing sunspots to global warming seems inadequate, somehow.
> Betting on sunspots to reverse a century of adding carbon to the atmosphere via fossil fuels is a bit of a long shot bet.

What possible basis could you have for making this judgment? I dearly hope that folks aren't going to accept only the science that agrees with their previous public policy goals. In the face of new evidence, one's opinions are required to change.

For my part, an ice age is more scary to me than a hot age. I can't quite tell if that's just because I personally hate cold weather or if my observation that humans seem to thrive more easily in warmer weather is a fact.

Incidentally, that global warming happens is a sure thing. The magnitude and effects of global warming aren't any more of a sure thing than predicting sun spot activity.
I appreciate the post and am a huge fan of Yehuda, he used my comments as teeing off points for your remarks but I feel that what I was trying to say has been lost in his response, probably because I was unclear.

Lets start with this ...

"The Rails core team does seem to treat the project as if it’s a personal playground"

This was said more in frustration with the coffeescript/sass decision than any real belief that it really was the case.

I understand it may be hurtful and disparaging of the amazing effort that the Rails core team has dedicated to making Rails fantastic, and I apologize unreservedly.

With respect to outlining the changes (prototype to jquery etc), I'm not complaining about the changes per se (because I like most of them), what I'm complaining about is the pace of the changes.

Something as major as the asset pipelining feature (where you move assets out of the public folder and into the app folder), for example, seems big enough that it should be a 3.2 release not the next release after an already major change in 3.0.

See what I'm saying?

I haven't worked on the Rails core, so this can be taken with a pinch of salt, but I feel like it would be a good idea to adopt the Intel tick tock refresh style of cpu releases http://en.wikipedia.org/wiki/Intel_Tick-Tock, where major releases come out on the 'tock' and are refined on the 'tick'. That would work well for Rails releases, giving major releases enough time to settle into the Rails consciousness before the next set of changes comes down.

It was great to get a thorough explanation of the rationalization behind the decisions that have been made recently, it would be awesome to see that increase in frequency.

I just want to thank the Rails team for all the hard work and have them understand that while I may argue hard for what I believe, that I have nothing but the highest regard for them.
That sounds reasonable. So why did people buy tulip bulbs instead of land in the Netherlands?

It is probably because people are comfortable with the familiar. Sure, a warmer earth might be a positive-sum change, but there's an equally good chance that it won't be. So why take the risk of losing what you have if you can avoid it?

It sounds like a reverse lottery of pain to me. If LulzSec looks at you, you get to spend millions beefing up security while your competitors do nothing.
Wait, is LulzSec actually doing anything interesting here or are they just DDOSing everyone? The EVE Online comment makes it sound like it's just a bunch of guys with LOIC...
I feel like if you've got lots of text and embedded code mixed together in a template there's probably something wrong with your architecture.

For the few cases where that makes sense, ERb is great. But I have a hard time imagining it's common enough to make it the default.

Edit: Also, the post you linked to outlines several simple ways to mix text into your HAML (inlining HTML, using markdown filters, etc)

My comment from the other link:
reference: http://solarscience.msfc.nasa.gov/SunspotCycle.shtml

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.

BTW, the last chart in that paper is pretty amazing.

Any idea about how well it works with stretch marks?
The "similarity" of two images is a very complicated concept, when people are asked to tag images the overlap rarely goes above 20% on average (e.g. check out http://images.google.com/imagelabeler/ and try your hand at it). Think about it: you may think at the object level (both images have cars), concept level (both are happy images), color, etc. This is why large online stock image sellers still rely on tags extensively.

As a rough analogy, consider a textual example: Find a sentence similar to "It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife." Now, if you enter this sentence in Google, it retrieves documents that contain it, in TinyEye fashion. What other similarity is desired? Should it retrieve essays on Austen, on marriage, 17th century English literature...?

If you are interested in image similarity search, check out the Pascal challenge (http://pascallin.ecs.soton.ac.uk/challenges/VOC/voc2011/inde...). The advances in the last 5-6 years on object detection and visual feature extraction (which image similarity relies on) is amazing.
I'm not a restaurant guy but I am known to be able to read income statements with my eyes closed :)

Assuming the GP was generalizing "Rent" to include all expenses associated with the physical plant and presence, the sample income statement linked is close enough to that 30% number.

But your call on whether my assumption is too generous :)

Like you, I had three "issues" (deaths in my case) close in time. I get a lot of "Well, you know, things happen in threes." The last time someone said this to me (yesterday, in fact) I replied, "Yes, I know. When I count them, I start over every time I get to three. Things always happen in threes."

Went right over her head.
I'm intelligent enough to know that if it there was a "more complex reality", you would have astutely pointed it out. The truth is that the situation is very simple and that those who try to veil reality in complex sophistry are simply parasites who wish to benefit through the misery of others. Shame on you!
Always Remember You Have Options
First of all, it's not up to you to define compassion for others. Neither is virtue.
Secondly compassion, virtue...all that has no inherent value other than the value you decide to give it.
Thirdly, did you ever question your own behaviour? I don't agree that visiting the sick has any positive purpose at all.
What exactly does a visit do? You could argue that a slight improvement in mental wellbeing may or may not happen and it may or may not speed up recovery. So you would call that slight possibility a "most value-creating activity a person can do"? I sure hope not.

A person doesn't get better from a visit, they get better by being left alone with medicine.

Your view on society is adorable, but remember that it has no roots in reality.
Wow that's embarrassing!

Why All The Daily Deal Hate?

I use TinEye a lot and I think this will be great. My typical uses of TinEye, that will probably be improved with the bigger stock:

- somebody put text over a nice image and I want the unmodified version

- searching for bigger, better quality versions of an image (e.g. wallpapers)

- finding other images from the same author/gallery (since it links to the sites that hosts the copies)

- finding the name of the movie, person or object pictured (because copies will be hosted with different, probably meaningful names and in pages with subtitles)
The point of the article was not to admonish people for their counter-productive efforts, but to answer the question "What should and shouldn't you say to someone whose sick?".

To his list of things NOT to say I would add your sentence "If people say or do awkward things, appreciate the fact that they made the effort at all."

Well, no. I'm sick! Why should I "appreciate" your "efforts" if they do nothing but add to my misery and pain.
I could imagine it, as always, being the guys that paid for it.

It is embarrassingly slow. I did some tests a couple years ago, on ActiveRecord 3.0.pre, and its 20x slower to initialize empty objects (no database access) than DataMapper, or just making empty Ruby objects & hashes.

I've not see Economist Debates before but it looks to be a very well thought out environment for debate. They roleplay the form of a debate so well that it inspires courteousness from the general audience. The timetable and structure of the debate as well as the expert commentary is all very nice.

I'd like to see such a system for political discourse. At the local, state, and national level, it would be a welcome place to share ideas. If all the major news organizations are going to keep spewing opinionated journalism, we may as well take it to the logical conclusion. With opinion should come debate.
One quickly realises that you must mean a balanced tree, since otherwise there would be no unique solution, but it would still be nice if it was explicit in the text.

Ask HN: Are You Interested in Solving a Really Complex Problem? 
Hey HN,
You are always amazing at helping me finding solutions for my startup so here is my problem tell me if anyone can help. I started a startup with 2 other doctors and we have been working for couple of months coming up with solutions to problems we think we can fix in consumer healthcare in the US. We have finalized something and it's very exciting. My issue is that I am a front end guy (PS, HTML, CSS, JS) and to make this work well I need an awesome coder that really likes to work on complex problems to help me part-time making it happen. I will give founder equity to who ever can help and like I said it can be part-time if your busy.

That's assuming that there is any kind of natural 'regulation' of the earth's climate. It appears to veer erratically from mini-ice age to heatwave. However it's true we do need to vary carefully consider the downsides of any potential interventions and be flexible about it. There's far too much dogma and polarisation of debate in climate science at the moment.
"Startups aren’t easy. They are a never-ending..." Most important point is right there at the beginning. Things never end and if you don't make a point to celebrate the victories along the way... You'll wear yourself down always looking off at the next hill you have to climb.

It's too easy to fall into a pattern of always worrying about the next milestone instead of appreciating the little ones. I need to do more of this.
I could trudge around in my databases to read direct user to user messages. Should I? Should I sell a tool to facilitate doing so?

There's a deeper problem that Yehuda isn't hitting and that is that there is an inverse correlation between being cool and cutting edge and being consumer friendly.

Rails is, and really has always been, a framework which changes very quickly. Although virtually all of these changes are for the better either in some abstract feels-better sense or in a tangible practical sense, each of these changes imposes a cost on other people.

This isn't really a problem with the decisions of the rails core team, it is the entire ethos accompanying rails. Authentication plugins I remember from 4 years ago are barely maintained today, and there are a whole bunch of new ones. I'm guessing my knowledge re: authentication has a half-life of approximately 1.5 years.

The implications are as follows:

(1) If you are a Rails developer you need to be a full-time Rails developer and not do too much else. You can't do Rails and a bunch of other things because Rails will take up a lot of your time.

(2) Think you can code, release, and forget about it? Think again. If you have projects, you (and the people who commissioned the projects) need to know that these projects need to have at least 5 hrs / week budgeted for the indefinite future (perhaps less, but the point is that they need a developer on staff -- they can't simply be released and forgotten about).

(3) Extra caution, since not all change is good change. You may end up to subject whatever is cool at the time. That's not to say that this really affects the core team, but there are a gazillion Rubyists out there attempting to change everything over to MongoDB that works just fine in whatever flavor of SQL they were running before. A lot of people have been burned here.

All of these take away from the promise and excitement of Rails for many people -- which was not simply "oh we can be on the cutting edge of technology," but "oh, we can have a sexy app with decent functionality up in a matter of a couple weeks with half the budget of what we thought." That second impression, which is what a lot of the Rails ecosystem is built off of, is largely false (esp. now that there are a bunch of other quickstart web frameworks).
If you recall back in the Rails 1.x days, it wasn't exactly pleasant to learn -- if only because of the awful documentation.

Point being, Rails' first priority is to improve developers' productivity, sanity and happiness - all developers using it, not just new ones.
This is the most thoughtful and thorough advice I've received. Thank you, I will work hard on the onboarding process, and take your advice.

Why stay on the treadmill for 45+ minutes? I like exercising, but that sounds like torture. I'd much rather do a short, intensive set of weight-lifting, an hour of yoga, or other things I actually find enjoyable in and of themselves. By all means do what's best for you, but if it's that monotonous, you may want to look at other options.

I'm not sure where you're getting your numbers from. At $30 billion over the next 10 years, per year, US aid to Israel is $412 per Israeli [1]. And of course, that will go down with population increases.

And another thing to note is that that money is in the form of military contracts with American companies. It is not used to pay for Israeli infrastructure or social services AFAIK beyond a separate chunk of money ~$40 million to help pay for Israel's immigration problem [2].

You should link to it in your profile.
The other variation would be that "God has a plan", which is ironic since, philosophically speaking if there is a God, it is impossible to know how He thinks or acts. Even answering if this statement is true or false would mean that we are Gods ourselves.

The correct version would be "God works in mysterious ways".

Also, "everything happens for a reason" is a truism in the sense that every action has a reaction, but otherwise if you replace "reason" with "purpose" it fails the falsifiability test.
Look, I'm a "hobby philosopher", so I hope you'll forgive me when I say that you are wrong. Does your sense of empathy extend to random people on the street? 'Yeah, sometimes' you say. Okay, but it has bounds right? You don't help every single guy with all your power. So what are these bounds? They are the result of give+take, which you can call "quid pro quo" transaction or not, however way you feel most comfortable.
You'll just have to wait and see ;)

people say that, but while 10 minutes of weightlifting makes you a little stronger, as far as I can tell, it doesn't really carry the same endurance or health benefits of an hour of cardio.
