As I understand it Wave core principle is actually simple. When you do email, the fundamental unit of communication is the email. In Wave, the fundamental unit of communication is the conversation.

Unlike physical mail, most emails don't stand alone. They are part of a conversation. Conversations can get quite complicated. In mailing lists, they often get very long, effectively taking the shape of an HN thread.

Now, plain email is a mish-mash of message/IM/docs. We already use it these ways. Wave, by being very permissive, make these tasks easier. Single messages aren't harder, ML-like conversations have an enforced structure (easier to follow), and the collaborative editing thing just emerge from the possibility of modifying the entire conversation.

I see Wave like I see Lisp: a simple and consistent core, which allow many possibilities.

Initial impressions are good. Very clean, intuitive, and useful.

You could add more value in the cover letter and interview reminder section, and also add in a resume section. For example, in the interview section a person could create a list of stuff they need to look at or study, and then check them off as they're finished. Similarly, you could create and save different cover letter and resumes. A user could use special syntax like [[Edit company name]] to just edit the relevant parts and send the resumes off.

I can see this working with a very cheap subscription model ($1-2/month) if there are more features. I dont think have you have enough to sell it right now, since most job sites have their own job tracking system.

it is important to know if your car is FWD/RWD/AWD. you don't want to do this if you have a FWD or AWD car. the brakes will be applied to a powered axle and the brakes will just roast. (front brakes = majority of braking power, or all of it depending on car, when you hit the brake pedal. rear brakes sometimes reserved for e-brake only)

that being said - applying brakes and full-throttle to a RWD car will either bog down the engine/transmission and do nothing if under-powered, or if you have some power it will break traction while the car stands still, effectively "burning out" your rear tires and smoking them. then you can do fun things like donuts :D
I think it's unfair to compare cars from 50 years ago against cars today without comparing the behavior of the drivers. Although the cars themselves may be safer, more people may be on the roads and may be driving more recklessly which would lead to a higher number of accidents as well as having the damage be equal.

I remember reading something about a study being done that showed people that cars drove much more dangerously around bikers with helmets than bikers without; if you feel that other cars are safer you may drive more dangerously.

Edit: Here's the study: http://www.bath.ac.uk/news/2006/9/11/overtaking110906.html
Me too. Also, knowing that the DOM will be structured as I intended it to be is a good thing...especially when traversing/manipulating with JS. There is an HTML5 parser that will tidy up those omissions but I doubt that will be implemented consistently across all browsers.

Leaving the browser to tidy up after you is IMHO bad practice.
But now he's seen that it's not worth spending the time developing a full application.

Writing a toy program is how most developers explore a new framework start to finish. In this case, submitting a "Hello World" or "Tip Calculator" application as a test was very revealing.

The point of the NoSQL movement is not to advocate a specific technology (e.g. Java, CouchDB, etc), but merely to encourage people to consider NoSQL databases for the 5-10% of cases when SQL works poorly.
I read the post twice and failed to find any criticism.
We find no evidence of any adverse consequences as a result of the incentive programs. Incentive schools do significantly better on both mechanical components of the test (designed to reflect rote learning) and conceptual components of the test (designed to capture deeper understanding of the material),suggesting that the gains in test scores represent an actual increase in learning outcomes. Students in incentive schools do significantly better not only in math and language (for which there were incentives), but also in science and social studies (for which there were no incentives), suggesting positive spillover effects....
The author gave a great talk at Windy City Rails [1] on this topic. He talked about two domains - biology and comics - and showed how absurdly complex a SQL schema would be that modeled them rigorously. I hadn't really understood a practical case for schemaless databases, but his talk was helpful (and really funny).

1. Turn off that annoying snapshots hover-over-link-and-see-a-screenshot crap.
On the last slide he writes that "We believe that the primes do not observe any significant pattern beyond the obvious ones (e.g. mostly being odd)..."

But is there an even prime other than 2? I guess not, otherwise it will be divisible by 2.
Then it would probably be more useful to focus on the problems that the specific databases solve, rather than talking about them collectively in such a general manner. It makes it hard to focus on their strengths.

I would love to read a really detailed comparison of CouchDB (for example) to RDBMSs for common uses, by someone who thoroughly understands the relational model and is very familiar with (say) Postgres or Oracle. I like Postgres and SQLite, but I'm curious about CouchDB - it's a different kind of tool, and it probably has several complementary use cases.
Shouldn't it be possible, with what we know about cryptography available today, for banks and other companies to do business without having to regularly pass around files containing thousands of their customers' most personal identification credentials like names, addresses, SSNs and account numbers?

>> "especially when traversing/manipulating with JS"

The DOM is great. It's a pretty well designed API, and makes things easy.
HTML/XHTML are just crappy ugly serializations of it. It'd be nice if there were some alternative serialization schemes supported by browsers more like JSON.

If you're manipulating the DOM with js, then you can't far wrong. You can't omit closing tags. You can't have invalid nesting. You can't typo closing tags. etc
>Thanks for your hunch.

Actually I was being facetious. :)

> Does deleting it remove the lost karma?

Not that I can tell. My guess is that 'deleting' a comment actually sets a 'deleted' flag somewhere in the data base rather than actually removing it; but I haven't looked at the code so I'm just speculating.

> Is the idea of negatively voting down a comment ... To encourage the user to delete it?

No. The purpose is to encourage commentary that follows the site's discussion guidelines:

http://ycombinator.com/newsguidelines.html (see section titled "In Comments")

In fact, the window to delete a comment is only open for a set amount of time after posting, after which the site withdraws the option to delete.
If the car didn't have a scratch (ie. the energy wasn't dissipated by the crumple zones), a lot more of the impact would be felt by the passengers.

"increasing student test scores"

Yes, paying teachers more for higher test scores is a very good way of increasing test scores - this was found in california schools years ago. It had an opposite effect on students actual learning though.

You're better off if the front end of the car dramatically collapses during an accident. It may destroy the car, but the more force absorbed by the crumpling, the less is delivered to the passenger.

Hi. I used your site about 9 months ago as my main tool for organizing my job search. I was the guy who emailed you with the suggestion to have links open in a new tab versus navigating away from the site (which you implemented a few hours later!). I am happy to say I am now gainfully employed as an Oracle DBA at a large company. I have recommended your site to friends and they have used it as well.

AAA+++ would use again.
I remember the dark ages. When the retailers would have a few Macs tucked into a corner somewhere. And tapping the keyboard would only get you the password protected dialog box. "Guys, I'm trying to buy a computer here. I don't give a fuck about the screensaver."

It amazes me that some retailers and manufacturers still haven't learned this basic lesson. A pretty shockwave video playing, highlighting the useless crapware installed on their PCs. And it's still password protected. Like just the fact that I'm standing in front of it is enough to break it. That's pretty reassuring.
Brilliant.

Do you know if most people in the US ever use the neutral gear in automatic transmission cars?
The problem is that if I were 37 Signals, I would not respond on their blog as that would give you what you want: attention to your blog and your product. If you seriously expected that, you were mistaken.

And now the real problem is that you have tarnished your own credibility as 37 Signals has actually shown the facts of the case. If you had simply asked them before going public, you could have avoided that and might have even found a real culprit after some detective work.

I don't agree with troll marketing. 37 Signals hurt their own reputation with the blog post about Mint just as you are hurting your own. They were roundly thumped for that as well.

And yes, I do have some kinds of relationships with 37 Signals, Mint, and TypePad. However, no relationship in the world will distract from this fundamental idea: if you're going to accuse someone publicly, you should get your facts straight first.
You lose about 1/2 inch of body height throughout the day through vertebrae compression. Their height difference could simply be down to him being in the US for a long period of time, I know having been to the US and currently living in Canada that any trip back to the UK means major sleep problems, I'm up either majorly late or direly early. Could it simply be that he gets up far earlier than his brother (British culture is notably more 9-5 than NA culture, where 7-3 is highly noticeable, at least here in Ontario)? Would the increase weight mean faster compression of his vertebrae or even excess compression compared to his twin?

Not to mention posture and everything else, including flat-footedness (which IIRC can attribute a decrease of about 1/2 inch in height due to a posture shift), which again could have been induced by excess weight. Both twins could be genetically prone to flat feet, but the shorter one simply gained weight and increase the strain leading to a collapse earlier in life.

Perhaps this is DNA methylation, but I'd bet anything that a mixture of diet, exercise and physical health are greater contributing factors to divergent physical characteristics in identical twins. I mean one simply taking a disliking to milk through childhood, or getting repeatedly put in detention could have a large enough effect over time to decrease physical height by less than an inch.

I had this experience too, the last time I was job hunting, and it seems pretty rude, especially after being told "we'll call you within a week." I would have been happy with a boilerplate email. It would have saved me some anxiety and unnecessary follow-up calls.
What isn't clear to me is, do safer cars translate into fewer traffic injuries and deaths?

I recall reading an economics paper that indicated that safer cars encouraged more reckless driving and the two competing factors canceled each other out; as cars got safer, the number of accidents increased until the number of deaths and injuries returned to their prior levels.

I wonder if we all still drove 1959 cars would we be using cell phones while driving?
It was only a 2 year study and the first year had no positive results.

A teacher motivated by incentives receives their motivation externally. Motivation in such a form is never sustainable I don't believe. Over time, I would expect the motivation teachers receive from incentives would decrease over time.

Is there a feature to remind the job seeker of upcoming interviews?

I'm not sure about the "selling" of the site right off the bat. This is a good niche to be in for revenue. Possibly you can match seekers with jobs proactively, let contextually relevant ads and targeted banners serve up high-paying clicks and impressions. Then find a way to charge for "premium" services.

What language/framework did you use to create the site?
Haggling for Hot Dogs
Very cool site. One thing I would upgrade.

You have your "interview reminders" section. Very cool. The data is entered in a * / * * / * * * style, very intuitive for entry. However, I would RENDER the information in a set of nested ul tags.

Just my $.02
Exactly my thought. Hence the situation the US is in now - teachers don't get paid for performance, but school districts do and they force all kinds of behavior on teachers, namely teach how to pass THE-CURRENT-IMPORTANT-TEST.
Now that's hilarious!!
a "thanks!" getting a -1 :-)
I was working on a similar thing, i.e. co-relation between the size of comments and their usefulness, 'coz I wanted to limit the chars on the comments in my next app and also the level of nesting. This analysis helped me and so I said - "thanks!"
Very complicated in an automatic transmission car it seems. Very simple in a manual transmission car. You just press the clutch. You could even stop and start again and drive around with a little abuse of the clutch pedal.

Proper protection in a car crash means two things: you must be safe from being crushed directly, and deceleration must be slow enough to keep you from internal organs injuries and injures to your neck. The first is taken care by firm safety cage of the car, and the controlled crumpling/deformation of the front of the car slows down the crash taking care of the second case. More time = less deceleration = less stress on your body.

Sturdy cage only is not enough—you would not want to be dropped from sixth floor in metal safe, would you? The safe itself may survive the impact "without a scratch", but that would not help you much…

Thanks for your suggestions. With resumes, I feel like there are a few good web sites out there already. For example, I use emurse.com which is free and does everything I could want it to.

I really like your idea about having multiple cover letters and placeholders in the cover letters. Something like that would have been helpful for me so I could see quickly which parts I needed to change. It would also be fun to code up an interface for it.

On the money side, I was thinking a one-time payment of around $8 would allow use of the site for up to a year. A subscription model sounds good too, and probably the best thing is just to test.
The article fails to mention statistical significance of race versus religion?

Because this data makes sense, I hesitate to protest. Nevertheless, I'd be interested to see if race is statistically significant versus religion.
If linguistic specialists can work this well for accents inside the UK, I'm sure they'll be able to tell if you're lying when you say you grew up in Somalia to Somali parents, but you're accents indicating you're from Kenya or Ethiopia.

The boundaries between Somalia, Kenya, and Ethiopia were drawn by European diplomats in the nineteenth century for their convenience. Those boundaries cut across the territory occupied the ethnically-Somali people themselves, who (if Wikipedia can be trusted) are traditionally nomadic and who frequently marry outside their own clans. So if some linguist claimed that he could identify the origin of a Somali-speaker the way Henry Higgins could trace an English-speaker, I would be very very skeptical.
Useful feedback that's very easy to implement: thank you very much sir.

When two cars are going 40mph there is an immense amount of kinetic energy. That kinetic energy has to go somewhere in order for those cars to stop. It can go into the frame of the car, it can go into the passengers, and it will into heat and noise. But it has to go somewhere. Until they build cars out of space Nerf they found on a passing comet we can choose to have the car crumble and absorb the impact or have the passengers absorb it.

But who is to say what those 1.3M results will mean for future readers? The article's point is that "future history" may choose to interpret the Manhattan Project as some kind of myth.

There's stuff in antiquity that is mentioned a lot, yet we're not sure if it had any historical basis: Atlantis, the Great Flood, King Arthur, Prester John, etc. We're not sure if Archimedes ever built his heat ray, or if the formula for Greek fire ever contained anything special. We only just recently discovered that the Persians inadvertently used carbon nanorods to create Damascus steel, and we're still not totally sure how they did it.

(Also, there is a lot of garbage on the Internet. For some unknowable reason, "moon landing" gives 3.6M results on Google, while "moon landing hoax" gives 3.9M results...)

Huddle Launches iPhone App, Microsoft Office Plug-In And Web Conferencing Tool
Not directly, no. Since 1959 cars are going faster, there is more of them, and the bar for driving one is lower because of ubiquity and social expectation. So it's about the same.

Just more cars, and more people driving them, so we see more crashes. I'd say the percentages don't matter as much because of how many more cars and roads there are. Even if they'd be marginally lower -- you still get many, many more crashes and injuries.
I don't think it would work at pricing like that. I'm guessing this is something people will only use for a month or two (until they get a job). However you price it factor in that you may only retain customers for 2ish months.

What about adding interview email reminders? send me an email 24 and maybe 3 hours before I have an interview to make sure I haven't forgotten it.
