Ask HN: GIS - offline routing with javascript?

I want to build an GIS application (HTML5/JS) with abilities to do some routing while the used device is offline.Dijkstra and A* should be enough in this case, but I would like to know if there is already a offline library for this particular task, I don't want to reinvent the wheel. I've thought of a adjacency list using JSON.There are some routing services out there, but every service...

apparently there is no reason for them.

even with PRISM and others, people are too lazy for that.

the most difficult task in the whole world. and they have to be excited... but where I live, nobody gives a sh.t what NSA does with all the private data.
What's with [RetroShare](retroshare.sourceforge.net)? Another question: What's the sense of a tool that nobody of your friends uses, especially in social networking? The will not migrate until Facebook etc. shut down
Re:How should hacker parents protect their kids online? on Sunday September 15, 2013 @05:29PM (#6390384)
First: I'm a teenager, if that matters.

I agree with you that ISP protection wouldn't be a good way, I secretly think Cameron just uses this as an excuse for something else (who knows).

- I think the parents should decide what is good and bad for their children. My parents are very liberal at this because they know that I have more knowledge about that field than they would ever acquire (voluntary ;).

It's clear that nowadays you're not able to forbid the online world to a socially normal teenager or even some kids. So you have to show them what the risks are and you should escort your kid while playing online games, introducing them to the www.

You should also be aware that teenagers are able to evaluate the situation properly (most of the time). if your children are well-bred they know how to behave, even in the online world. You should just remind them sometimes that the online world is not a extralegal or completely mindless room, they have to maintain their manners.

If you cannot escort your kids (I'm not talking about the teenagers yet) it's better to install some blocking mechanisms, so the kids won't accidentally view 4chan's wired subsites or the like, but there's the thing with parenting: you cannot prevent it 100%, so your children should learn how to handle that stuff, too.

The WWW is a great invention, but it contains some dangerous things for kids. You cannot prevent that your kid will see porn or other nasty things, so the only way to handle this is to prepare your child. - it's hard to do good parenting in the 21st century, everything's changing so fast.

hope your kids turn to lovely parents :)

they didn't fix that issue since 2009. - another reason to use firefox. I've encountered that while designing a pixel-perfect website where firefox just give me the expected results while chrome hadn't the same results, didn't look good. sucks, but as a webdev you just have to accept it and work-around.

it seems to be relatively simple to brute-force, because the used set is small compared to possible keyboard letters. but for most real world scenarios it should work, if there are only spammers who don't investigate and just ignore it. thus maybe not for high-traffic sites.

it doesn't seem insulting for me, perhaps my username led him to call us monkeys (what humans are, kind of ;).
Re:Be the best? on Sunday September 15, 2013 @04:39PM (#6390244)
so it's a process built upon a calling and without any comparisons to other? the last part is read into it, but you get the point; I think these comparisons affect the motivation - even if you don't do it for that. - i.e. this blogger stopped with ballet after she saw better ballet dancers in her course.

Re:Do you still use Captchas or moved to something better? on Sunday September 15, 2013 @04:24PM (#6390180)
There are some alternatives, i.e. where Captchas are only displayed when JavaScript is disabled. But all these methods don't work, at least someone just can analyze the traffic and do all the JavaScript-Stuff in a single HTTP/TLS Request, because it's not truly server-side. I know it's embarrassing to use Captchas, but at least for the registration it should be used. Or you could use OpenID or some social network oauth system to avoid Captchas.

I didn't think of that long-term view you described. reminded me of some one-hit-wonder artists - thanks for that, but what's the way for a long-term success? the best one retains in the highest branches i guess.

Be the best?

What do you think about being "the best one" in your field? I noticed this: I don't start things because I know there is someone else who comes up with a better approach (oh, does the idea exists? search on github, find a repo, stop investigating). - think what you want about this perfectionist all-or-nothing, but please comment some cases where you did exactly the same so I can feel a bit...
