peregrine.io | Software Engineer | San Francisco, CA | Full-time | ONSITE
Founded in 2018, Peregrine provides public safety agencies with technology to make data-driven decisions, power real-time operations, and strengthen community relationships. We do this through openness, accountability, careful policy enforcement, and respect for people’s personal freedoms.
We are inspired to work hand-in-hand with public servants. Our customers are our partners; we listen to their needs, learn from their experiences, and develop software experiences to help them do their best work.
We are looking for strong developers to join our small but growing team. As one of the earliest engineering hires, you’ll take on a lead role with vast ownership across one of our stacks. You’ll be able to work directly with end users to deliver a world-class, high performance SaaS platform.
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.
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.
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...
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
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.
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.
