>Our teacher always said she accepted all result with an error of less than 10% if we did that by making the calculus easier.

In English, calculus and calculation are two different things. And there are a number of grammatical errors in that sentence that make the meaning unclear.

I'm noting this because if the teacher allowed you to do simpler calculus so long as you maintained an error margin of 10%, that's different from allowing you to do simpler calculations provided you keep an error margin of 10%. Calculus is specifically the branch of mathematics involving limits, functions, derivatives, and integrals, and from the English it sounds like she, if we are being perfectly pedantic, was giving you the option do do approximations with your integrals and derivatives, not with any value you like.
Gnome really needs help with their typography (and design in general).

Gradients, docks and shiny icons do not make a well designed product.

It's clear to see it suffers from the curse of open source software – design by committee, and the featuritis that results from that. There's often "flashy" chrome in OSS, but no solid interactions behind to back it up.

It's equally important what you choose to leave out from your product, as what you include. It seems Gnome has included the kitchen sink.
My feedback:

- Landing page does not tell me what the site is about. Who is it for? Something like the one suggested by @spking needed.

- Carousel is too fast for me. It should also pause on hover to let me check.

- Heroku and AWS is most probably unknown to your target userbase. You should drop it from the carousel, IMO.

- Not urgent, but you should work on the YSlow score. Lots of the scripts are unnecessary for the landing page.

- Make the hover animations on the "features" pages discoverable. No one will notice them.

- Can't you make a shorter version of the screencast and put it on the landing page?

Overall, there are lots of features inside, but screenshots are too crowded and copy is not helping much in the landing page.

For example, there's a lot going on in this screenshot and there are many screenshots like this one in the landing page carousel (http://nationbuilder.s3.amazonaws.com/3dna/pages/36/features...). You have many features, but select something simple and stick to it for the landing page.
I agree too. That's a really good point too about needing things to "pull you down the road". Really great ideas and feedback, thanks!
That sounds like something I said. Are you making a point or just flattering me?
I think this would really help political candidates in countries such as Canada without fixed election dates, where elections can begin with little notice. Our election just started a week or so ago and parties were nominating new candidates for some ridings at the last minute. My riding still doesn't have a candidate for the Liberal party.

Certainly these new candidates are starting the campaign flat footed with regards to their web presence and social media strategy and this favours the long established incumbents. This service could fix that and get new candidates that haven't had time to prepare up and running as soon as possible.
BTW, I'm working on a webapp that needs subscription billing. Who'd you go with, and why?
I had the same problem, I thought the author mistakenly used ∏ but I see in my browser tab that it's correctly lowercase.

"Redis - A persistent key-value database"

http://redis.io/

"Redis is an open source, advanced key-value store"

I'm not sure what sort of extended commentary you expected about Redis - it isn't quite as important of a project as you seem to think it is (seriously, are you always commenting on HN?)

EDIT: In case this wasn't already painfully clear, Antirez has an annoying habit of constantly moving the goal lines, making it virtually impossible to discuss Redis in any context unless it is pure, unbridled awe and praise. Then again, Antirez is a HN "celebrity" so expect nonsense like the above to be voted up by the proles.

I don't have a link, but 37signals did some research on this. They also practice and preach requiring a credit card at sign up. I think it really depends on the market.
My initial feedback is that there are too many pricing layers and that is confusing. Maybe have a few and then do some sort of step function.

I like the idea, I think it makes a lot of sense and this market probably really needs this sort of thing... that being said, I don't know the market AT ALL.

Give me a shout if you want to talk payments, we can probably help you figure out the best way to manage that.
I don't think that's done. It's not good for them (they would have to pay heaps of tickets) or you (you show weakness).
As far as the idea goes, I think it's great, and very polished. Nice work!

I had a bit of a bad initial reaction when I heard the name, however, as it feels very imperialist and negative to me. Might just be me though, so just take it as a single datapoint. But my suggestion would be to look into names that are a little more positive.
Ask HN: Feedback on the redesign of our app
We are currently working on redesigning our app so that it looks more fresh and beautiful.

Our aim is to provide a more modern looking and visually appealing software that makes all the UI elements understandable and useful.

This is where we started from (aka current version):
http://dl.dropbox.com/u/5912/Jing/2011-04-07_0134.png

And this is what the design looks like on our dev server:

http://dl.dropbox.com/u/5912/Jing/2011-04-07_0131.png
http://dl.dropbox.com/u/5912/Jing/2011-04-07_0135.png

We are still in an early stage of the re-design, but I just wanted to get some feedback on the current design / color scheme, since we are almost done with that.

I appreciate every feedback.

Thank you so much!

This is very true, but I've also experienced this with credit card sign ups. People who really don't want to pay will sign up, and forget to cancel. Then they'll file charge backs and complain when they get charged. Requiring a credit card may eliminate not-serious buyers, but it makes the ones that actually get through even more of a pain to deal with.
This is amazing. How long did it take to spec + build? What's the background story?
I would bet that will happen with Google android devices which will be coming integrated in high end vehicles, such as the Tesla S1000. Then hopefully, these will trickle down the stack to mainstream vehicles.
While much is made about passwords being sent across the open net, almost every site short of banks allow you to reset a password with an email, which is a close to identical problem.
The JSON streaming stuff is in 1.9.3, but you can do the same thing with yajl. :-)
That's a great idea, hope it goes well.
Surely nothing can go wrong with this development.

</snark> On a more serious note, how many times have we heard such things, and why has it taken so long? People have been using crappy GPSes for quite a while now, and more recently their cell phones to do things the car manufacturers have known about for years, but done nothing to support.
> doesn't change anything about the current political setup.

A startup doesn't have to do that. This startup is solving the pain of the politicians, and looks like they may do that well.

You're right, but I'd be more concerned about ppl forgetting to cancel with a 30 day trial. A 14 day trial is short enough that it'll stay on users' minds.
Believe me - in the open source world Gnome is the one that leans towards minimalism.

Any comments?
I don't think you're a racist but I disagree with your conclusion and further think you took it to an extreme that inhibits reasonable discussion. Apparently in the hypothetical.

Our politics clearly couldn't be more different, but I didn't set out to offend you. I'm sorry.
True that; you never know what a congressmen will do for attention or money after the money they bilked from another has already run dry.

And I have no clue as to ur exact mode for how you plan to monetize, and the ramification that'll arise off that. But I def believe you when you say you thought of some nifty ways.

Re: poker pros who use Twitter; a lot of their prop bets aren't necessarily financial, and just incredibly humorous and extreme otherwise, though i understand why you'd want to totally steer clear of any potential headaches right now. Idk, though, I'd still bet you could do something there and be as kosher as a Hebrew National.

Really awesome, regardless; ill def follow what happens and give it a go as a user.

Next version sounds perfectly planned. Be sweet to get some "highly" followed people using it till, then unleash v2.0 on their followers/observers. Perhaps Bill Simmons as your inaugural celeb user?
You're obviously very passionate about politics. What's your background, and how are you going to fix the problem?
Ok, well, at least you are now saying something. But it may very well fix/improve the situation. We will have to wait and see. I think it's an interesting trial at least.
Thinkpads offer a way to limit the percent State of Charge (SoC) while charging. AFAIK this is the only laptop which does so.

I do this manually by removing the battery from my laptop once it reaches 70-90% SoC (and I'm plugged in, obviously). This is superior for battery protection because the temperature is limited to room temperature, but inferior because the laptop shuts off on power loss.
Here's the text with full list of covered technologies. http://www.microsoft.com/interop/cp/default.mspx It's not the same as the Novell deal which happened before the promise.

In short it's - as long as you conform to the specs, you're ok (no limits). On the other hand "Partial implementations are not covered.", so in practice anything could be argued here ;)

It's just such a grammatically poor phrase and it gives the impression that the entire project lacks polish and thoughtful design.

I think you're off to a great start. Looking forward to seeing you grow the service.

I recommend heading over to the http://www.advrider.com/ forums - it's a great community of riders (mostly dual-sport) and I'm sure you'll get great feedback there. Also, try to observe how they set up meetups for rides - it might help you decide on which features to build next.

As for the site itself - I love the design, not as macho as other sites out there. I wonder how riders will react to it (I'm guessing the scenic riders might like it more then adventure riders - but who knows).

Good luck!
nice idea. i'm typing this on an x60 with 2GB. this would be even easier on linux, i guess. on the other hand, i added an ssd recently and the effect is similar (since the sawp file is on the ssd).
YC Summer 2011 Applicants Live Web Chat
During the last funding round, 619cloud setup a web chat and a bunch of us had great conversations talking about our applications.

It would be great to do the same thing again - meet other applicants and chat about your ideas.

The room is at http://wompt.com/chat/yc/

I and my co-founder built Wompt (after not making into the last round ;) and are summer applicants.

Look forward to meeting ya'll.

I attended a pedagogical course in college.

This is exactly one of the topics of that course -- some children do not fit in.

Teacher gave an example of this one fat kid she had that was aggressive and obnoxious to everybody, while failing at tests and even skipping classes. She then began to treat him nicer and praise him for every stupid achievement of his, while talking to the other teachers to do the same -- the child had a miraculous recovery; as it happens he was being aggressive in response to how he was treated by other teachers and colleagues.

It's not that teachers don't know this, BUT the public school is overwhelmed by too many children. In my 1-4 grades I was in a classroom of 30 children (I'm not in the US, and that number nowadays is more like 20-25) ... how can you, as a teacher, attend to the special needs of 30 children, everyday?

Private schools have the resources and the capacity for smaller, more focused classrooms, with teachers that are better paid, and thus happier (well, at least in some cases). That's the only real difference that makes an impact, IMHO.
As a counter-point, using computers was an essential part of my education when I attended a Montessori school. I agree with your conclusion though; schools like this might easily adopt the "pathologies of the community".

As an aside, I think the biggest benefits I received from attending Montessori were independence and self-motivation-- I was never forced to learned something, I had to want to learn it first and pursue it myself.
Things aren't so bad in Denver where I live.
I have a friend who raised a small amount from an unaccredited investor. The investor was a trusted family friend. The startup went nowhere, and the investor lost all her money. She was irate and demanded all her money back. No matter how much explanation you give of the risk, some unaccredited investors will still not understand.
My son knew the alphabet too at that age. He is now 5 and has forgotten and relearned it quite a few times since then. Knowing this, I wouldn't worry about it really.
I think the reason that open source software is so often poorly designed is this committee approach where no one person can lead the design team. Strong leadership is extremely important when designing a good UI and I feel a lot of open source projects forget this.

Also this leader needs to be thick skinned and self confident enough to take criticism from others on the project but also assert their own subjective views.
I wish I could get a car with a place to securely mount an iPad or Android tablet and supply power to it. They could leave out the stereo, mapping, and big display and let me use whatever device I choose.

I currently use my Android phone to play music and make phone calls through a Bluetooth-FM adapter in my car. I just got a Bluetooth-OBDII adapter (eBay, $20) and the Android Torque app (https://market.android.com/details?id=org.prowl.torquefree) which can show just about any operational parameter of the car - speed, fuel pressure, coolant temp, trouble codes, etc. There are only a few things I can't do through the Android - control the temperature and turn on the headlights. That and having a good place to mount the Android is the only thing missing now.
really awesome idea... I think your underestimating yourself a little in thinking they didn't get many submissions. This is honestly a good idea executed well.

Congrats on winning.

You do realise where you are posting right?
You could do all that stuff. Or you could switch to an entirely different playing field. How about hiring your developers in the Rust Belt where they work for a third less and are unlikely to be poached by other startups?

Surely you're joking right? Create a billion dollar company where it snows four months out of the year? Yes and a recent example rhymes with coupon;<).
They're just reusing existing API, which seems like an obvious step for a start. The features are there, so if you actually want to write your LINQ layer on top of whatever storage is available, you should be able to do so.
I actually see this article as a good sign. This kind of article could set the tone for the beginning of sane discussion about the SQL/coSQL ecosystem and how to move forward in developing a shared toolset for developers.
I don't know if this is typical in the creative agency world, but it's definitely not good.

It doesn't matter what they call you or what they pay you, highlight the full size projects that you've taken on.

Yes, but then the canonical URL would be on github.com.

OpenGL on Java is still pretty immature. There's still plenty of issues with the library Minecraft uses, LJWGL, especially on Mac and Linux. Support for OpenGL itself on non-Windows OSes is also often lacking, especially on ATI or Intel graphics cards.
I have a hard time believing that. Around here, Montessori schools are private and expensive. These school are all established is wealthy neighborhoods, so even if you forget that they are expensive, you still need a pretty good income to live in a place where it is convenient to get your kids to school everyday or be willing to go through important sacrifices for your children's education.
Obviously there are other great places to locate, but the Bay Area remains the hub. Startups have to compete with several 800 lb gorillas!
I genuinely don't have a horse in this race, but I am far from convinced that learning concepts sooner is a recipe for long-term win. In many cases, I think you just get to the same place sooner at much higher levels of effort.

B should always be done. Close family can be a good way to raise money. Generally, they see it as a gift with a potential upside. It's the friends of friends or friends of family where it gets really sticky.
Hey HN, just thought I'd share a little toy project I put together over the weekend. It's basically just ChatRoulette over the phone. Pretty sure its only appeal will be novelty, but it was one of the ideas I had when I was toying around with Twilio's API, so voila.

One idea I had for making it more interesting/useful was allowing you to select a "category" or "location" so that you could be randomly paired with people from the same location or people with similar interests. Any thoughts?
It's not about being passionate about politics and my background is in mathematics and cs, two of the least political subjects out there. If I was going to devote time and effort to doing anything political then it certainly wouldn't be about empowering the marketing/spin machine used by politicians. I would instead focus on tools to empower individual citizens and give them the tools to fight back the spin machine. This doesn't do anything of the sort.
that's the rub - i'd be perfectly happy working at $co for what they've offered me, and getting a regular annual raise, and i wouldn't stay at $startup at all, without the prospect of an acquisition, even though they're (now) offering me a good bit more than $co.

the probability of being acquired is essentially the carrot, and the founder talks as though it's practically a certainty, but he's the overoptimistic sort. the problem is that i pretty much have no insight into the business/financial aspect of things, and therefore have no real way of judging the probabilities myself.

i'm actually not very motivated by money, but when the numbers get high enough they have a way of distorting reality around them.
Thank god for readability.

@antirez as in any mathematical proof the most generic case is considered first. If X is a special case or is exposing special corner scenarios, I'd assume that could be covered by extension proofs.

A few days ago, I added experimental to my Debian apt list and apt-getted for about an hour until gnome-shell was working. Very unstable, partially configured, not really revolutionary, etc. Headed back to Gnome 2 only to find out that GTK 2 and GTK 3 have a hard time co-existing. Twas very difficult to get my system back to normal. I'm an idiot; don't be like me.
I consider myself a power user and I've been happily using Gnome for several years now. It's got just enough room for customization that I can configure it to be a very efficient workspace, but it doesn't require me to spend days or weeks configuring it and learning a new way to use my computer.

But it looks like this release might be enough to drive me away. The app-based window management paradigm just doesn't work if you regularly have 8 console windows and 4 browser windows open on a single virtual desktop. My working style used to be well supported by Gnome, but now it's been completely dropped.
