brudolph··on Show HN: ThingsOnReddit – Products linked to on Reddit
Thanks, this project uses Ruby on Rails 5 with Webpacker (React). I've found making websites quickly with Rails is very effective. The data can be found on Google BigQuery and I then used Scrapy to scrape Amazon pages for further product info. It's deployed to a DigitalOcean node and connects to an Amazon RDS Postgres instance.

The conception of the idea was Tuesday. The next thing I knew it was Saturday, and I felt ready enough to post.

Thanks! I'm looking forward to iterating. The suggestions you lay out are great. I'll hopefully be adding features / changes as time goes on. This was an initial MVP in order to get feedback quickly, and it worked! Appreciate the thoughtful response.

Yes, amazon dominates the product links, so it was easiest to start with that. In the future though, I'd love to add more.

Are you guys hiring outside of the UK? Specifically, are you hiring from the US?
brudolph··on Stanford Free Classes – A review from a Stanford Student
I'm sorry if I made it confusing, but it really isn't about whether I signed up for 229 or 229a, the point is most of my classes for the coming term are now under this new online format and it would be shame to see them lower their standards to fit the public.

CS229a didn't exist prior to the online courses.
brudolph··on Stanford Free Classes – A review from a Stanford Student
Class meetings were optional (which I did attend) and only a fraction of the students actually attended. I don't have a problem with cs229a being easier than 229, but the thing is a lot of other classes have now turned to the online format with no alternative (like 229 to 229a). Selfstudy is great, but sometimes the best way to learn is from a structured class.

I agree with with zuck knuth comparison perhaps I too quickly wrote the first two names that came to my head. As for the image, I like to make people think I go outside...

Ah good catch!

Didn't realize this was such a huge demand, I was always more interested in the content, but I'm definitely going to add the comments link
brudolph··on Hacker News Instant
Cool, thanks, I'll put it in for the next version

Yeah I didn't handle any cases for other languages since most of the articles are in english. But I feel ya on making search engines for multiple languages, had to do that this summer and it was a nightmare
brudolph··on Hacker News Instant
I used a suffix tree over a suffix array because I hadn't heard of suffix arrays, but after glancing at the wikipedia page for suffix arrays it seems those might have been a good choice too. I'll look more into it. I did all the tree building myself, and I'll explain that in my post. The post should be ready by tomorrow.
brudolph··on Hacker News Instant
Working on that as well, it's the question mark after gates that is throwing it off.
brudolph··on Hacker News Instant
Yeah it'll grow as time goes on. Once week ago was when I was happy with my db structure and stopped dropping all the contents in it.
brudolph··on Hacker News Instant
Thanks, currently it doesn't link to any comment pages, but hopefully in the future I'll add it
brudolph··on Hacker News Instant
haha no, just my friends in my dorm watching me launch it

Sure, I'm going to be writing a longer blog post on how I made it, but for now here's a short summary:

I made a script that scrapes all the links from hacker news every 15 minutes. I then open the links and process the text using python's nltk package (deciding what words are important and useful). Then I used a suffix tree in a mongodb backend to store the important words in such a way that once it looks up a word you can get the set of documents pertaining to the word. This way the search is linear in the length of the query and not the number of documents. The rest was just some jquery ajax calls and parsing of the search query.

I'll look into a new design, maybe make the orange's white and the white's orange.

Thanks for the feedback! As time goes on its article database will grow and it'll be more useful
