Social dog kenneling and dog walking. Basically AirBnB for dogs.

Basically when you go out of town you can leave your dog with other users on the site who have dogs and vice versa. Every time you take in a dog of another user you earn karma points. When you kennel a dog with another user you spend karma points. Users get a certain number of karma points for free upon signing up, but once they've used them, they much take in the dogs of others to get more back.

This site could also be used for dog walking as well. Maybe even bathing dogs could be included.

The site would need a Terms of Use that limits the liability of those that participate and those running the site.
I am not sure if that's a solution for education, or the summary of a certain Pink Floyd song.
I always thought rye and most whiskeys were just what people drank when they couldn't afford or hadn't acquired a taste for a good scotch. I'll have to check them out.
Wonderful! I stand corrected then. This app is proving to be useful and educational.

Social Babysitting.

A social network where parents fill out a profile of themselves and their child and the site tries to match up parents with children of similar ages and interests. The parents then can meet one another, check out each others homes and introduce the kids to each other to confirm compatibility. Once that is done, these mutually compatible parents can rely on each other to babysit each others kids when necessary.

The site would keep track of karma points between parents.

This would permit couples to have more alone time together without having to spend lots on babysitters.
I already do this to an extent! It is indeed part of the added value for the business, but when I first started coding it up a lot of it was because I missed coding and was looking for an excuse to write more.

Yotophoto.com

Was the web's first search engine for libre (free to use) images, mostly Creative Commons and Public Domain. One of the things I'm most proud of was a "search by color" feature that was very fast, accurate and way ahead of what anyone else was doing at the time (IMHO).

Yotophoto was doing a million searches (~100k unique) per day at one point.
A: it's smart to stay up late.
B: smart people stay up late.

I think the article is saying B :)
The author, Aaron Swartz, harps on the fact that the film doesn't show enough teaching and instead "hides behind charts and graphs." The author would rather the film show "terrified kids up on the big screen." This seems to me like favoring anecdotes over data.

The author also attributes the crisis in American education to standardized tests. He doesn't back this up. Standardized tests work well in countries like China and India, from which so many of our engineering grad students hail. Granted that no standardized test is perfect, it boggles my mind that Swartz would call it the educational crisis.
UserVoice for congressional districts as an alternative to lobbyists.

The idea is to use technology to disrupt traditional lobbying to the point that it is more difficult for the bad lobbyists to have a negative impact.

With the science of reputation and filtering systems getting better by the day, one solution might be a service that makes everyone a potential lobbyist. There are about 118,000 citizens per pair of ears in Washington according to Clay Johnson, author of the blog InfoVegan. The website I am suggesting would allow all 118,000 people an equal chance to voice their opinion. Those 118,000 opinions are then voted one by those same 118,000 people. The most upvoted items "float" to the top and get past the filter to the Congressman or Congresswoman's ears.

If you also make it so that people can't link and vote for opinions directly, you remove the one major avenue used to game the system: one person with too much time or influence spreads the link to their idea to those likely to upvote it.

Instead the system can be designed like a double-blind experiment. Ideas are stripped of names of people and organizations. The system randomly assigns ideas already submitted to be upvoted or downvoted to all participants. A participants ideas does not get submitted for voting by others until they have "bought" that right by voting on the ideas of others. Participants get a limited number of upvotes and downvotes to use, thus preventing them from giving out too many of one or the other and being forced to make a judgment call.

Those are a few ideas, but there is no reason the mechanics of voting and reputation systems can't be used for this end.

As I said above, this is a bit like UserVoice for government in that it allows users (citizens) to "lobby" the product managers (congressmen and congresswomen) for product feature requests and improvements.
Fantastic app. Didn't think I'd make the outlay (it's pricey), but for any tedious tasks I can turn them into a challenge with Regexes and Macros. I really love it, thanks for putting it together and for charging so it is still around today.
I'm in for November 28th! I was just thinking about an idea for my next project this morning- looks like now I have motivation to build it.
Are you talking travel or moving?

Moving: I find I do a lot of research online first. I look at the areas of the city that tend to be younger and vegan friendly. I try to find tech meetups/groups as a way to meet new people, get friends, and make business contacts. I explore a lot. Try new restaurants and businesses regularly, go out of my way to meet new people.
It would help us immensely if you tell us why 9 months and what you hope to be able to accomplish after 9 months. That will help us point you in the right direction.
I found this article pretty hilarious in that it goes on and on about how the movie fails to provide any clear examples of what makes a good teacher and then fails to provide any clear examples of what makes a good teacher. It's like the author not only assumed that we knew what he was talking about, but that we already agreed with him and hence didn't need to be persuaded by examples. This wasn't really an argument so much as a long-winded expression of a single persons opinion.

Also, the last time I checked, you can't just "memorize" your way into passing standardized tests outside of perhaps spelling and vocabulary tests.
Twitter did not increase conversion rate by 29% by adding "1 extra step".

Comparing the Before and After:

- Before uses CAPTCHA, After does not.

- Before uses green "arrowed" image buttons, After uses plain grey CSS buttons.

- Before does not show users a progress bar, After does.

- Before does not use floating field explanation screens, After does.

- Before is set against a green background, After is set against blue.

I buy in that the extra step is helping, but attributing 29% to that single change is inaccurate.

The handful of points above properly tested against ~350,000 new signups a day certainly could have driven the majority of that impact.
really nice :)

I think I'll use it to register my next website ;)
I agree standardized tests focused on memorization aren't educational, but surely tests that require problem solving ability (math) are worthwhile. Without standardized tests, how else are we supposed to quantify how well students and by extension their teachers are performing? The author doesn't suggest an alternative here.
JRuby sounds risky on Harmony. The people behind it focus on J2EE and Rails.

The Eclipse Android plugin is solid and comes with a user interface builder. Not the best tool in the world, much worse than Microsoft Blend but on par with Samsung Bada for Eclipse. Eclipse really is a fantastic IDE.

Remember that multitouch is the big feature and that all helper API´s are Java. This might bite you in the ass later in the project if you go the "interesting" route.
I don't know that technologists really indicate what the general populace will do; they tend to try new things less often and will continue to use the same product long after it's life expectancy.

The document is 3 years old and posted on scribd, maybe it's not a "social hack" but just something I felt at the time.
I have experience with TimeForce, and it was pretty easy from an IT perspective. We used a digital punch in box, and then had it networked back to our main office from two locations.

The technological challenge is already solved. You could do something similar like www.hipmunk.com, and basically solve the social and interface problems.

We ended up pulling the system out of there for social reasons. Time clocks hurt morale.
Vertical farms are a terrible idea and I am baffled as to why this isn't apparent to everyone [1].

Here's just a few of the glaring errors from this article:

Lower fossil fuel usage

This is daft, and comes from massively overestimating of the energy costs of harvesting and shipping food around[2] and massively underestimating the energy costs of growing plants under lights. When plants are out in the fields they're getting solar energy for free. When you've got twenty stories of hydroponic equipment, you're having to generate all the energy they need to grow yourself.

Organic

There's no reason that molds, fungi and pests can't grow indoors.

every idle office tower project could be bringing in $1.5 million dollars a year rather than losing money.

Only if you forget about running costs. Energy costs themselves will be staggering. [3]

[1] For one thing, I find it telling that the people who are enthusiastic about vertical farming always seem to be highly educated city dwellers and never people who actually grow food for a living.

[2] The words "food miles" are always a massive red flag.

[3] £9.82 of energy required to grow half a kilo of wheat http://www.monbiot.com/archives/2010/08/16/towering-lunacy/
Barcalounger or Laz-e-boy are good options.

I would also consider getting an iPad and using Instapaper to save all your reading for one big chunk of reading time. When reading time comes around get out of the office and go sit on a park bench or in a coffee shop. You can also deal with emails once a day the same way.
Blackberry managed to crack into the mobile market by offering devices that didn't do telephony at all. The "current smartphone obsession" as you call it has been developing for a decade now. People who primarily want to make phone calls from their phone is a dwindling market. For business, on demand email is significantly more important. For teens, texting ability is much more important (my daughter never calls anyone). There's a cultural shift in the works here.

Telephony isn't that difficult and all "american-style" smartphones do a perfectly adequate job. If you can make calls and answer calls, it's a phone. Most people don't need anything more than that. I don't see what more Nokia can offer on that point but they lots of room to screw everything else up.
I have a feeling - that was the point.
They have wireless Internet ;-)

Maybe someone who has voted this confusing essay up could explain why.

The author is saying, the problem with education in the US is not that poor teachers are nearly impossible to fire, but is really something else?

It seems an improvement making it easier to fire poor teachers would be of great help. Why is the author highlighting this idea as an example of a bad idea? To me, this would be the most positive single change that could be made.
I did, and it was, just not for very long. http://news.ycombinator.com/item?id=1743533
It was a dark and stormy landing page. Rain rolled off the roofs, gathered in the gutters and flowed over my shoes to the drain. I needed lots of things, a drink, a broad, and a gun, but first of all, I needed a mobile app to get me a place to dry off and a really first rate coffee while checking in and getting location points.

Here is that app.
Here in Memphis, where we recently received a $90 million grant from the Gates Foundation, it would be nice JUST to graduate kids who could read on a middle school reading level. Forget sending them to college or trying to create some kind of creative class out of these kids, they don't even have the basics. THAT is the problem. We aren't even getting these kids a mediocre education where they can read, write, add, subtract, multiply, and divide.
I frequent Starbucks and it is always frustrating, even though it lasts for a second, that signing into their network requires me do exactly what this article talks about. Each time I login, I'm hopefully that an engineer has fixed this.
Interestingly enough, their own poll along the right hand side uses radio buttons, but does not have a roll-over effect as proposed by the article.
We make MinuteDock (http://minutedock.com). More of a standard time-tracking program than a clock-card machine, but serves the same purpose

Hmm ... maybe you should get an iPod Touch with a MiFi. Or, of course, perhaps Apple will eventually make an iPod Touch with a sim card like the iPad 3G. If it did that with the same data price plans, that would be really great.
Is this the new Intel CPU?
Not always is "exponential" a bad thing. For small sets, the expo algorithm is actually faster than the polynomial one. Although yeah, generally speaking, it's a bad idea.

I run a bakery, so I found members of the media I wanted to get along with, got to know them, and gave them free samples of my products. Many of them are now customers and friends.

I imagine a similar process would work for online-only businesses.
Sounds like a most excellent plan, count me in!

http://diabeti.ca has languished as a landing page for too long. Time to clean it up, get it out there, and get more people using it besides my wife.
Awesome! Back when I worked at a bank we used to do timed challenges over at http://javabat.com (same thing but for java). Now that I hack Python all day this is much more my thing, although it's not that much of a challenge, it'll give me somewhere to send the greenhorns.
A few minutes if someone (who hasn't wasted his time on HN :D ) already compiled the latest version for your device. Otherwise one can spent months trying to get the poorly documented and sometimes incomplete code to work.
The point being that the worth of a teacher is measured by their students' scores on standardized tests. So which teachers are 'good' and which are 'poor' (i.e. what the 'correct' method of gauging teaching success), seems to be the arena of disagreement.
My goal is to get a paying customer for my database webapp builder. I've got two interested parties, I just need to close the deals and get them to agree to pay me :-)
I'm wonderfully amazed that coreutils has factor.
There aren't many 510(k) submission & workflow apps.
In terms of actual solutions, I think programs like KIPP are promising. If someone can demonstrate the right way to run a school system on a small scale, we can learn from it and encourage adoption of those changes nationally.
Yes, it does for me with Firefox 4 on Windows 7. This is something that would be browser and OS dependent. In general, I've noticed OS X tends to have much fewer places with rollover effects than Windows.
How odd.

You'd think that would come in handy for their new phones and apps.

It would be interesting if the blocks of code were labeled with what they do.
you also probably don't want to memoize, you aren't going to re-use, so why waste the memory?
I solved all three problems in under a half-hour by writing quick-and-dirty Java programs to do it. The standard libraries provide almost everything I needed; the only thing I used other than that was Maple to factor the number. I'm pretty sure mucking around with CPAN libs such would have taken me longer. Granted, my solutions were brute-force and not very elegant, but for simple problems like these with small inputs I can write code to solve it faster than finding the answer elsewhere.
I'm using Chrome on Ubuntu. I didn't realize they meant OS/browsers needed to take this into account. I just assumed they were talking about things to consider when designing a web application.
I recommend everyone see this movie and decide for themselves.

I don't know if it will have this effect on everyone, but I haven't been able to stop thinking about it since I saw it. For me, seeing this movie was one of those experiences that divide your life into the part before it happened, and the part after.

I read your argument, and then thought about what you wrote while reading your comment again. Then I realized that your argument is an argument against your argument.

Good teachers engage their students and make them think about problems around them and how to solve them. They present history as then ask if it's happening again around them. They teach English and then explain why learning the proper way to talk and write helps make their own expressions more poignant and well received.

In today's school system's the teachers are judged solely on the test scores of students and it's unheard of that a student might simply be a 'c' student instead of being the teachers fault. Teachers have to teach the tests and no longer have the proper time to teach theory and critical thinking. School lengths change at the whim of the school board depending on why survey has been read saying that 50 min classes are better than 90 min and so on. The school system has become a political playground and we are seeing the result of focusing on 'grades' over education.
I have to say that I think the new logo is pretty terrible. It's obvious that they were trying to be clever, but the problem is that, in my opinion, the "space" is too weak of a space.

The litmus test I use for a logo is to imagine that I were to make a batch of stickers of the logo, that I wanted to go around and stick on walls or whatnot. How well would the logo stand out? How would it make use of the space? And to me, a sticker of the word "My" followed by an underscore does not pass that test.
Your question more or less assumes that standardization is the right answer. Let's start a step or two back: Do we need to measure students and teachers at all? Presuming we do, why do we need to do it via standardized tests? Do they even measure what we want to know?

My daughter goes to a school that does well by these measures. It _is_ a good school, but the teachers basically teach to the test* -- given the rather punitive structure of the laws, they don't have much choice. Performance is directly tied to funding. Is that really the best way to teach kids? I'm doubtful.

I think we do need good teachers, but I'm not at all convinced that test scores are a good way to measure that, anymore than lines of code are a good way to measure programmers. I do want kids to learn, but I'm not very convinced this is the best route to that.

I don't think there is any easy solution. Kids with parents who value education tend to do better -- that's a huge factor. Resources certainly help; those of us who care tend to live in better school districts (often with higher tax rates) -- is that really a sensible way to run the schools? I mean, it works for me, but why should we under-resource kids whose parents don't care about education? But there is no doubt that you can pour money at this problem and get nowhere if you spend it poorly. (That's true of all problems, though.)

All this emphasis on education can go overboard. Where I live, even in grade school they get only one short recess a day (unlike the two, slightly longer, ones I grew up with). Does that make sense? In a nation with a national obesity epidemic? And, even in very early grades, they come home with a LOT of homework. When are they supposed to go outside and play?

*I don't mean they literally teach the tests, but they certainly spend a lot of time structuring their materials around the way test questions are phrased, and in teaching kids test-taking strategies. Do I think fourth-graders should need to learn how to take tests? No.
I use vimperator for the types of things you have mentioned. Keyboard shortcuts for everything very similar to vim.

But in other comments you seem to ask about actual terminal capabilities. Not really interested in that personally, I am fine having my browser be a browser and my terminal be a terminal. Might be neat to run an instance of a terminal in a browser tab though.

But I do recommend learning vimperator if you spend a lot of time in the terminal anyway.
I wouldn't be surprised if the missing captcha is entirely the reason
Tx so much :)
I have a few friends who went to the original Sudbury school, Sudbury Valley School.

One of them recently suggested that supplementing their school's non-curriculum with Sal Khan's online exercises (explained here: http://www.youtube.com/watch?v=wRf6XiEZ_Y8) might make for something close to an ideal education.
You have less than 30 Fibbonacci numbers to compute.

That 317811 is divisible by 3 is obvious upon adding its digits together.

Once you've verified that 514229 isn't divisible by a handful of small primes, you don't try to prove primality. Instead factor 514230 and stick it in. After dividing by 2, 3, and 5, you've got 17141. It doesn't take that long to run through 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59 and 61. At which point you have an answer you can try plugging in to discover it is correct. Which is a sequence cperciva pretty definitely has memorized. (I do.) Or alternately cperciva may have better factorization techniques memorized.

If you already have a routine around for factoring (I do), then this takes longer than coding it. But I could do it with paper and pencil pretty easily.
I'm disappointed that it is possible to solve by hand, as that undercuts the reward. This is one of the great aspects of ITA's programming problems: none of them are even solvable by brute force.
> Actually, if you don't have a rubber duck you could at
a pinch ask a fellow programmer or engineer to sit in.

In my experience the rubber duck works better because it doesn't try to talk back to you or interfere in any way.
I have been procrastinating for long and want to do it this time. I was thinking of two ideas as I put in my above link and decided to work on an app for hosting the contests of fellow Startups.
Get a personal wiki program like ZuluPad and start making lists of things you need to do to build your business. Break each thing into many small tasks so you can check them off and see the progress you're making.

I've been working steadily on my startup since I left my job in April. My "DONE" list has 88 items. Last night I finished another task: adding proper logging to my web service. There are a lot more tasks on my "TO DO" list, but now there are none blocking me from launching the beta version of my service next week.
