This is general psychology and applies just as well to product design as it does to marketing. Too much choice can be a bad thing both because it clutters up the flow of your product and because humans just aren't very good at picking their optimal set of choices. You wouldn't release a Twitter clone to the public that required you to check 100 yes/no feature boxes just to set up an account.
So it is not really a practical option, considering that you need to make money and the process of entering a new market just to learn may take several years, until you learn enough to build anything close to already established competitors.

edit: unless the competitors suck really bad, of course.
Show HN: ForgetTheTextbook.com, Let the best teachers win 
I'm a long time lurker on HN, and among other projects, about two years ago I began creating a textbook replacement.

www.forgetthetextbook.com

In short, it's a free, crowdsourced, and dynamic online textbook that rewards quality instruction. It's ideally a platform anyone can learn or teach from in every subject, and I hope it will harness the Salman Khan's of the world.

Reddit gave me some great feedback over a year ago, but I've been so busy with my normal life and day-job that it has fallen to the wayside. It's still rough around the edges, but I wanted HN's opinion of the concept before I put more effort towards it.

Any input would be great.
Yes, there could be many lessons. I took as broad an interpretation as I could: if there is something you want to do, there is probably nothing stopping you from getting started and trying.

There's a catch-22 for me here. I love writing programs, and write my own programs for fun. But as soon as I'm hired to write somebody else's programs, it stops being fun.

Part of it is the language. Technical interviewers love hearing about how I wrote a cool program in Lisp, for example, but then never seem to want to hire me to actually write Lisp code. (I didn't learn Lisp just to show off.)

Part of it is the project. Virtually no software project I see these days looks interesting enough that I'd want to work on it. (Most software I don't even want to use, and even if it's free.)

There may well be other parts. But thinking back, I had one job where I picked the language and the project, and did have quite a bit of fun there, even though it was by far my lowest salary.

I would love to be paid for programs I want to write anyway, the way I want to write them. Still working out how to do that. :-)

Is it? The estimates going around of $10-$25 are for the chip only. You still need to SMT solder it to a board and connect power, storage, etc. The only currently immediately available Tegra ready-made board (tegra 2, which was cheaper) costs $110 at volume[1].

OUYA has to add plastic casing, power source, connectors, storage, wireless AND a wireless controller, and source manufacturing for many tens of thousands of those, QC and handling/shipment.

Those $2 million start to look short..

How I Turned Down $300l from Microsoft to go Full-Time on GitHub
I realize you are joking, but the concern really is that cab companies are something that consumers are trusting their lives with, and often in situations before they can evaluate trustworthiness or history, if not of entire companies then certainly of individual drivers. There are extensive regulations that have thereby been placed on such companies over the years related to vehicle maintenance, specialized insurance, and traffic organization. Uber believes that none of this should apply to them because they are being "disruptive" (as if that is somehow itself a benefit for which we should be optimizing as a society).
Twitter's attitude is laughable. Yes, you have a decent amount of traffic but you're also only dealing with ~160 uncompressed bytes (plus whatever overhead) per event. The hurdles you've overcame aren't that particularly amazing nor challenging.
Nope, you're not missing anything. row-fluid resets the grid, allowing you to pretty much arbitrarily dice up your columns however you want.

"And isn't the spirit of HN to be looking for and cheering the next new thing, not crapping on it in favor of the old established thing?"

How does grandparent's remarks qualify as crapping on anything? You don't even respond to his points. HN is not for cheerleading.
(FWIW, I took the emphasis and subsequent wonkier smily to mean he was joking, and in fact have accidentally sent such emails in the past from his own website.)
This is really surprising to me.

I can think of countless things that were okay when I was a kid, but illegal now. On the other hand, there's very little I can think of that was illegal then but legal now. From everything I've read, laws, regulations and even types of crimes classified as felonies are increasing and at an ever-faster rate.
This response fills me with unease. You present MMOs as a core use-case, and then equivocate your support for MMOs, preferring to hand-wave about failover and graph databases.

The best way to experiment with distributed systems design is to build a real distributed system - or at least be able to sketch one out.

Frankly, this seemed like a solution looking for a problem, and your vague responses are supporting this. The interesting dynamic, of being able to move data between nodes as a side-effect of access patterns is interesting, but it's not clear how an MMO could really use this dynamic to good effect. Indeed, even the fault tolerant case, it's not clear how this dynamic would help failover - I mean, would you need to duplicate access patterns prior to node failure to ensure dual-local data?

Frankly, I think you should focus on one use-case (MMO, graph database, something) and hand-wave a complete solution that really leverages the novelty of your approach. Get specific and talk about what actually happens when "things move".

there are numerous laws in place at local and state levels that prohibit purchasing electronics that do not meet this certification. the state of california is also governed by such rules (and will also have to stop purchasing apple equipment), as are parts of the federal govt

I think there is an increasing number of people here who have either stopped thinking big or never started. Disruption is becoming just a business meme like synergy and teamwork. Some people fear change and while the community here seems to embrace change there are many who are really, really scared by the idea of their world shifting.

Kickstarter is a great place to raise some money for an interesting project. Get a couple of like minded hackers on side, write a decent proposal and demo a product and you too can get a cool million. I'm sure that is terrifying for a lot of people here. They are afraid because its a threat to their dreams of making it or the way they 'made it'. They are afraid because they don't have any ideas. They are afraid because they have a choice.

I love the little guys who are trying to upset the big players. I genuinely adore some of the players out there at the moment who are thinking big and trying to do or make wholly new things. It's fantastic to see that sort of creativity finally getting attention and funding. But I don't think everyone shares my enthusiasm.

I think some people are just pretending and playing at being the type of person they wish they were.

Admittedly I am not well versed in Rails at present. However, the question in regard to twitter isn't so much whether Rails can scale but whether it could scale when twitter needed it too, which was a fair number of years ago. Did Mongrel or Unicorn even exist back in, say, 2007?
Could not agree more.

At the end of the day, what is important is to deliver a piece of software that works according to the customer requirements.

If the customer dictates the operating system, language, etc. Then it is already decided what to use.

If some technology liberty is given, then it should be something that is working as desired at the given deadline, regardless of the technology.

Ask HN: Planning a move from SF to NYC. Need help in salary comparison.
I'm planning a move from SF to NYC provided my salary negotiation goes well. Quora/Glassdoor/Cost of living calculators weren't really helpful so may be HN gurus can throw some light?

I'm curious to know what a 110K salary (Product Manager - 2 years experience) in SF would be in NYC? I don't want to intentionally short-sell myself (I'm sure Bay Area talent is in "high demand" in NYC as I experienced it myself) but don't want to throw out an outrageous number based on all these Cost of living calculators as well. May be folks who moved from Bay Area to NYC can comment?

Thanks so!

"According to stats from the Journal, this won't be much of a blow to Apple. Only about 500 to 700, or 1 percent to 2 percent total, of San Francisco computers are Macs."

So yeah, you'll have to pardon me if this strikes me as non-news.

"I think Apple no longer wants to follow the EPEAT recycling guidelines because they think not following them allows product designs that will be more compelling for consumers and bring more value to Apple than their continued participation in EPEAT.

And I don’t think it matters much. Apple still accepts their own computers for recycling. It’s not unreasonable to ask the people who recycle old computers properly, who I imagine are very few, to bring their Apple computers back to Apple to guarantee the “best” recycling."
>I mean that it does not solve a problem that cannot be easily remedied already. Buy/use a tablet with HDMI-out, hook up bluetooth controller.

What problem does a console solve? Couldn't I just buy a computer and hook it up to my PC? Why would anyone buy a console?

How many Android games work great with a bluetooth controller? Which controller with what features? How likely are you to leave your tablet hooked up to the TV? Do tablets cost 100 dollars?

The obvious interest in the device shows it DOES solve a problem. I sure hope these guys knock it out of the park.
Your cost of living in NYC should be equal to SF and you have the added value of being from Silicon Valley — so my gut tells me that you might be able to stick with your range. The factors that are going to impact you are what industry that you work in and what your previous experience was before your current job. Your best bet might be to talk to a recruiter and pump them for information...
Perhaps not if it was worded support DF development for a year but perhaps if it was reworded pay for the development of a tightly integrated graphical interface for DF[1] then it sounds like a distinct project with clear objectives. Perhaps the developer was planning to do this work anyway but pitched as a project I believe its well within KS territory.

Hi all. Thanks for your comments on this. I've addressed a few of the misunderstandings and concerns raised here on HN, Twitter et al over on my blog: http://daneden.me/2012/07/max-css-in-depth/
> "According to stats from the Journal, this won't be much of a blow to Apple. Only about 500 to 700, or 1 percent to 2 percent total, of San Francisco computers are Macs."

To expand on this, in 2010, the City of San Francisco spent $45k on Apple computing products in 2010[1]. Or, in other words: not much.

[1] https://twitter.com/counternotions/status/222879894848282624
The bigger issue is that more organizations than just SF have EPEAT compliance standards -- notably universities.

Sure, but how can you fearlessly refactor the code without having automated tests in the first place for example?

Technical debt accumulates interrest.
As I recall, Apple's opinion is that the recycling standards aren't keeping up. Which may be true -- these kinds of electronics aren't, so far as I know, particularly well-suited to begin with for the type of mass assembly-line recycling techniques that would have problems with ungluing a glass panel, and there are lots of recycling programs that almost certainly can handle that step, including Apple's own, but the standards won't allow you to mention that.

I understand it -- and do think that the decision is rational -- from a business perspective, but at the end of the day it's Apple making a conscious choice to make their products less environmentally friendly. That's completely fine for Apple to do, but its still disappointing that they're disregarding environmental standards.

More disconcertingly, one can see the comments here -- largely defending Apple and marginalizing the issue -- being completely different if it was, say, Microsoft.

"Asking the community for $1 million every single year to draw a comic seems a bit steep."

Here's the important part though, they're already paying it, and more. That's how advertising works. People buy stuff that's advertised and they pay a higher markup which goes to pay for the advertising which goes to pay for the content.

The only difference is that today it's very indirect. What's wrong with direct support?

Just to clarify things since I helped write the initial blog post about twemcache... in our original post, we had an error regarding the slab calcification problem we mentioned, this problem ONLY applied to our v1.4.4 fork of memcached. After speaking with the upstream maintainers, we learned that recent memcached versions have addressed some of these problems. These are the type of conversations we want to have.

At the time we adopted memcached, that's the version we went with and made sure it worked well in our production environment as we scaled as a company. We also open sourced twemproxy [https://github.com/twitter/twemproxy] which is a lightweight proxy for memcached which has worked well for us in combination with twemcache and may work well for others too.

We just want to reiterate that twemcache has worked well for our unique environment and any teams evaluating memcached should try all their try all their options, just like any other piece of software you adopt in your stack.

One of the reasons of open sourcing our work was to share our ideas with the memcached community to see what worked well for us and help everyone. For example, this is also how we treat our work with our MySQL fork [https://github.com/twitter/mysql] which we maintain in the open and have signed an OCA with Oracle to help get work pushed upstream so everyone benefits in the long run.

I don't think this will hurt them much - Apple is a consumer-oriented company, not government, business or education.

Students will continue to buy Macs and eventually the weight of all those purchases will bleed over into other areas, whether there are guidelines or not.

Governments will get a small propaganda boost for a bit, but eventually people will start to question whey they're so behind the times.

Business doesn't want to pay a premium for it's computer equipment, so no big loss there.
