I drank beers and chilled for a week while people were burning out coding for free. That's the most impressive thing I've done at an hackaton. I code 24/7 from Monday to Friday for the same company, sometimes on the weekends too. They said hackatons are optional so I took a break and was fresh the next Monday at the office ;)

> 24/7 Monday to Friday

That's 24/5.

Not particularly popular on HackerNews for whatever reason, it was the type of thing where I finished my project at 2:00 AM and when I woke up at 6:00 am to get it together to do my demo, it was already getting tons of traffic.

It got writeups in Fortune, CNET, Lifehacker, and DailyMail over the course of the next week.

My team (5 others) and I built an application that would help you revise or learn a subject by testing you about it, where that subject could be anything, from mathematics to Shakespeare. It worked by scraping the top 1000 Bing results and then scraping several levels deep from each of the results to generate a "map" of knowledge. This in turn could be used to ask the user questions, generated fill-in-the-blanks, mat…

How did you generate the questions automatically?

This is something I have tried to do with natural languages in the past but getting good, error free, unambiguous questions out of an algorithm seems to be really difficult.

Earlier quoted context omitted.

I'm interested to know more about the tools/techniques you used to scrap the sites and clean the results. I am working on scraping contents from a couple of sites and it seems to be a pain, probably because i don't have lot of experience around it.

If you are familiar with python then try scrapy[1]. You can also scrape websites using beautifulsoup4[2] [1] https://scrapy.org/ [2] https://pypi.python.org/pypi/beautifulsoup4

We actually used Node.JS' request module, combined with some NLP (using natural) in order to pick out the main content. This worked pretty well, but for our purposes we didn't need it to be perfect because anything like headers would be removed when we processed the content (not being full sentences).

Also, I would be very skeptical of anyone who claims to be coding 24 hours a day. ;)

I'd spent an intense week coding so was feeling a bit burnt out with a hangover. So decided to create a tube map of Bath Cycle Routes with the help of one other on the day. Many iterations later the map and the process through which the map is created is being used nationally and internationally. I've done workshops. Spoken at national conferences. The local tourist office hands it out. It's going to be in next month…

There was a thesis I read on automated metro map drawing which beautifully proved it's equivalence to another NP-Complete problem, and then proceeded to use a constraint solver to create locally optimal solution. Was quite a complex set of constraints. But it ended up with some good results.

That sounds like an awesome tool! If you don't mind me asking, is it publicly available to view anywhere? What language is it in? To second another comment, I am also working on scraping but for articles. In this particular example I am trying to figure out how to get the scraper to start on the first headline all the way down to the bottom, and not touch anything else. Any tips for how to get it to find the first he…

I would think it depends on the site... maybe some special html characteristics around the first headline?

I usually use lynx, which strips down the html and only outputs the text. News site tend to have the same structure for every article, so after passing the html to lynx, the headline for a news site article will probably be around line 5-6.
