You're right that the data center and the cloud will be very similar, but our assertion at 80legs is that both are very poor choices.

I'm not arguing that it's impossible to do crawling on the cloud. I'm saying it's near-impossible to do it on a large-scale on the cloud. 3500 instances is pretty good, but will still be an order of magnitude slower than what 80legs is capable of.

Now, if you show me someone that has 10,000+ instances on the cloud, I may agree with you!

Very interesting stuff. I did notice that this bug was due to a broken test procedure, a simple test loop during the initial write would have brought this problem out instantly.

If your code has an integer range of several 10's of thousands of input possibilities and it costs you next to nothing to run it why not exhaustively test that function?

That way your confidence goes up tremendously, just a couple of edge cases vs the whole range, I know which one I'd pick.

The run output would simply be two columns of integers, very easy to scan for errors. (the output should be equal or monotonous increase from day by day, and should not hang...).

Of course that's after the fact, but there is really no routine so trivial that you can get away without really testing if it does what you intended.
Styles change more often than selector names. If you're using semantic selectors, they shouldn't change much at all.

This is a problem with any sort of abstraction. When you write a function in normal code, you duplicate the function name and call signature in exchange for centralizing the body. In Sass, you're presumably duplicating the variable name in exchange for centralizing its definition. The same goes here, except s/variable name/selector/.

That's true, but now they have no competition.

And, in some sense, InDesign is pretty much "complete" as far as what people expect in the print publishing world.

They're now slowly moving into more long-document features, etc, so it can be a replacement for much of the FrameMaker usage out there.

But, in the end, print publishing is slowly dying, so the future there is unclear, anyway.
Why yes, you happen to be correct. It can be done with cat and grep, and really you can do it without cat! However, it's perhaps desirable to be able to do things like edit the todo/tofix, delete them, export them to your todo application of choice, etc, etc, etc, etc. So, while you're correct in that you certainly can do it with grep, you're severely limiting yourself if you choose to.

Nice setup. I've got a similar one on a server:
Each daemon runs on it's own jail. Each jail is created from a cloned ZFS "base" jail filesystem, so it doesn't take any additional space (except each jail's installed packages), plus there are all the nice ZFS goodies (snapshots etc). There is one package-building jail. Every http request is served from a jail running varnish, which serves as a caching front-end to all the other http daemons in each jail.

I am well aware that you should try and minimize classes in the HTML.

However, on large sites where, multiple people might be publishing pages with slight variations, it is preferable NOT to touch your CSS too often. The multiple class method gives you some means to control it. It also adds tremendous flexibility for libraries (see jQuery UI's method of handling multiple classes for styling widgets).

Naming your class="tabbedPanel" has added no semantics to your contents and there is no such thing as 'a semantic attribute' defined nowhere. It is just a good naming convention that helps the developer and the designer. Simply there is no semantic meaning to a <div> it is just a container.

How would you handle two tabbed panels, one that is red and one that is blue?

just my opinion

If your opinion is that science isn't science until it satisfies your intuition, it's not wanted.

It's obvious to anyone with two brain cells to rub together that the blogspam of a press release isn't going to have the citations of a study. I don't suggest psychology gets away without citations, but a cursory knowledge of the field would let you know the Stroop test is science, and that an examination of the actual study, should you care to put any effort into something other than your denigrations, would inform you that your flippancy is unfounded.

That's an excellent point - if you have a finite range, why not test all of it? - and I know software testing researchers who look into just that. The difficulty to keep in mind is that in a large code base, there are going to be many small pieces that have a different finite range.

> How would you handle two tabbed panels, one that is red and one that is blue?

Why is one red and the other blue? Surely there's some functional difference between them? I'd rather call them <div id=hot class=tabbedPanel> and <div id=cold class=tabbedPanel> if that's what they're really representing.

I have nothing against multiple classes - I've written a fairly-well-used JQuery UI Combobox plugin, and I follow the normal JQuery UI conventions for class names there (ui-combobox, ui-combobox-item, etc.) I do have something against replicating typographic conventions as class names - note that it's class=ui-combobox-item, not class="displayblock height1em border1pxsolidblue fontweightbold".

Twitter, producers of a web-app, have raised US$139M. This is US$1M more than Tesla, which is producing an actual product (electric car).

Something is very wrong with this picture...
That may be YC bias.
OK, let's start with the fact that OP never defines "willpower", whatever that is and for which each of us probably has a different definition.

The researcher in question studies kinesiology, in other words, exercise and physical health. It's pretty clear that in this context, "willpower" meant "ability to follow through on an exercise regimen".

Then, OP never explains the applicability or purpose or reciting color words in different colors.

It's called the Stroop Task, as was already pointed out, and has been well known for decades as an incredibly useful tool in psychological research. It's mentally taxing and fairly resistant to performance improvement from practice or preparation. This is basic knowledge in the field.

The Stroop Task is usually employed to measure impairment of higher cognitive functions, but in this case is being used to deliberately overtax those cognitive functions (which presumably include willpower).

You mean any more than an "associate professor of kinesiology". I hold my years of experience completing projects in the trenches against her psych lab any day.

Yes, more qualified than a scientist with years of training and multiple publications in a specialized field that you have demonstrated absolutely no knowledge of. Your years of experience "in the trenches" are completely irrelevant.

I am endeavoring to be polite here, but I'm frankly baffled by the sheer arrogance on display.

The suggestion is perhaps that people with uninformed opinions should refrain from expressing them with smug self-satisfaction or, failing that, at least have the courtesy to do so on a site such as Digg where that behavior is the convention.

Delegation experiment feedback & looking for a Python dev
I make social apps, but have realized there is a limit to how much stuff I can make just by myself. My app hit/miss ratio is high enough that if I can keep it up, it would even make sense to pay someone to help with my projects.

So I decided to experiment with delegating. If you are interested in helping, I wrote this spec to describe what the app would be like: http://etherpad.com/ZesZbqIR5Z

If you haven't used App Engine before but are otherwise a pretty good dev, this could be your chance to get paid for learning it. I'll monitor the comments here and you can also mail me at manga@bemmu.com

If my approach to this seems wrong somehow, do share your thoughts on how I should proceed to get people to help me out.

Valuations of web companies are the weirdest thing in finance.

I think the reasoning goes something like this: if they become profitable, they'll be massively so because many costs that the maker of a physical product has to contend with do not exist.

That doesn't give the beginning of a clue on how to become profitable in the first place though, and there's the catch.

Isn't "game-over flaw" a bit overstated? It's a serious blunder, but if the data you're authenticating is highly structured then in many cases it won't be exploitable because the final padding from the original message becomes part of the body of the extended message, as unparseable gibberish.

What kind of registration/hosting services do you use for these sites?

I'd like to be free to play around with small projects on the web, but the prices that I've found make me hesitate to start something that seems frivolous.

For example, at godaddy.com:
-1 year of registration for a .com domain costs ~$10/yr
-1 year of "economy" hosting costs ~$4.75/mo
This means that I'd have to spend about $67 before I can start hacking away on my weekend project.

Is this normal? I'm fairly new to working in the web space, and as far as I know it may very well be the case that people are willing to drop 60-70 bucks per year on a hobby website the same way they would, for example, spend $40-$100 on an Arduino + kit as a cheap way to play around with mechatronics/robotics.

Is that about right? Or is there an even lower-barrier-to-entry option that I've missed?
Actually the bias is induced by reality, YC just happens to reflect it and make it seem a bit larger than it really is. California gets between 40 and 50% of all VC funding in the US and around a third of all global VC investment.

Probably the South Pole.
Another way you could look at it is like this: Twitter, who produce a service used globally by millions of people every day raised $139M, while Tesla, who produce an object that only a handful have ever seen and even fewer will ever buy is getting 1M less to try to take on some of the largest industrial conglomerates in the world.

Something is wrong with the picture, but which of those two are more likely to make a good return on the investment could be debated for quite a while...

A good example of the ontology problem is the Venn diagram. Unspoken in every Venn diagram is the white space that stretches as far as the eye can see. That's the world that isn't categorized yet. Anything could lurk out there.

The more Venn circles you draw, the harder it is to introduce new territories that intersect with all the territories they need to. Along comes the purple Malaysian wolfhound with an eyepatch and the scheme falls apart.

And that's with true/false categories. What authority can decide what's music and what isn't?
Heroku (YC W08) is hiring an Evangelist and a Support Engineer
Err... As chemists Watson & Crick were light-years behind Franklin. They initially proposed a model of DNA where the phosphates were on the inside. When they showed it to Franklin she (along with other chemists) basically laughed at them, and the faculty ordered them to stop working the problem because they obviously didn't know what the hell they were doing.

Then they got a hold of Franklin's photograph of B-form DNA without her knowledge. Some sources say Wilkins, the guy who gave Watson & Crick the photograph stole it, others that he was just trying to be helpful, but they agree that Watson & Crick used Franklin's work without her permission to form their final model... with the phosphates where they belong, on the OUTSIDE, this time.

Franklin was very cautious and methodical: she wanted everything all lined up and double-checked before she published, and she didn't seem to realize just how important what she already had was. (She was after all a chemist, not a biologist). She wanted more data before she said conclusively what the correct model was.

Watson & Crick were rather impulsive, but courageous. Even though they were dead wrong the first time, they kept working and with Franklin's data managed to put together a cohesive, plausible model, which turned out to be right. They raced to publication, and didn't give Franklin any of the credit.

I'm not sure what you want to interpret from that about hard work, except that someone's hard work (in this case, that of Franklin) is usually required for a major success, and that if the hard worker isn't careful, he/she might not be the one to get the credit.

I think in a lot of cases there is a lot of value. You make an interesting analogy to the PC revolution, but Apple is now making huge sums of money by limiting user customizability and essentially telling people what they want.

If you take extreme customizability to it's logical end then everybody just ends up writing their own web-app front ends on top of public apis. I don't know that that's better. There are certain best practices that probably should be enforced. I guess you might argue that a sensible default would satisfy that need, while allowing for deviations for those who care.

The last thing I'll say then is that perhaps a community wants to enforce (or at least encourage) some cultural features. If people can customize out certain cultural features then you lose that ability. For instance, maybe HN wants itself to be a place where comments are ranked in a certain way so that new comments aren't completely buried and everybody is at least forced to scan over them. If you can customize that out, it possibly hurts the culture.
