federkasten··on Ask HN: Who's using Clojure in production?
We (Xcoo, Inc.) are using Clojure since 2013.

https://xcoo.jp

Our products using Clojure are :

- "Chrovis", which is a bio-informatics web application that analyzes and visualizes huge genome data sets https://chrov.is

- "Hacker News Hack", which is a web application that shows HN with categories and popularity http://newshack.io

Updated.

1. fix some bugs (e.g. "item.time_str")

2. support responsive design (currently optimized with iPhone)

Thanks.

You're right. That's nice idea! I will add that feature shortly.

federkasten··on Show HN: Hacker News with categories and popularity
It's nice idea. I will try it.
federkasten··on Show HN: Hacker News with categories and popularity
Yes. You are right.

I trained classifiers with hand annotations (about 1000 contents or so)

Thanks. I will support responsive web design. It maybe solve it.

Thanks. hnstream is really cool.

You're right. I have limited frequency of crawling due to HN's access thresholds.

hnstream will help me. I will try it.

Thanks. I will fix it shortly.
federkasten··on Show HN: Hacker News with categories and popularity
Thanks.

It crawls HN topics every one hour. So news in our application would delay up to one hour.

federkasten··on Show HN: Hacker News with categories and popularity
Yes. I will support responsive design in the near future.

I am planning to open source it in several months. (Our codes have not been well-commented and well-structured yet...

Our implementation and algorithm detail is followings.

Its categorizing process is written in Python.

Using nltk, it makes corpus with TFIDF model from HN topics and comments. And it generates classifiers from this corpus with SVM algorithm using scipy and numpy.

FYI, its web interface is written in Clojure and ClojureScript.

federkasten··on Show HN: Hacker News with categories and popularity
Using natural language processing and supervised learning, it automatically tagged news with 9 categories.
federkasten··on Show HN: Clojure Cup Application - Focus on Coding
Did you bother with naming of your new project? "Focus on Coding" can solve it.

It frees you from thinking about names, searching domains, and creating icons and logo images when you want to start new projects or services. You can input some keywords, then you can get candidates of names. After you select one of them, you can get a logo and icons.

You can FOCUS ON CODING.

Please try it and enjoy. Please vote for us, if you like it.

Our team joined the 48 hour Clojure Cup hackathon and developed this application. We are welcome to your feedback and comment for further development near future.
