In February, I did an analysis on all Hacker News stories: http://minimaxir.com/2014/02/hacking-hacker-news/ Yesterday, I published an analysis on all Hacker News comments: http://minimaxir.com/2014/10/hn-comments-about-comments/ There's a lot of interesting trends in the data. Let me know if you want to know anything in particular and I'll get back to you. :)

I would be interested to know the average hourly cost of HN in lost productivity :)

40 wpm x total words x (hmm need to look up productivity stats) - but we could do it :-)

I added upvoting stories and comments feature to my ios/android app few weeks ago. And thinking about adding commenting. http://hn.premii.com/about Now I will have to remove that. Please keep current version of the YC site on a different subdomain.

I use your app, it's awesome! Also agree with your request, as I said elsewhere in this thread...

By the way, animations (the slide between list and comments) have been jerky since a recent update. I'm using the Android app on an HTC One M7 with the latest stock ROM (4.4.3 and Sense 6.0). A few other people have mentioned this in Play Store reviews. Is this a known issue?

I'd like to know the average hourly amount earned from HN. I know personally HN has helped me greatly in the projects I do at work.

Yes this is an interesting question too, but one that is much harder to answer. I love HN, but it sure gets a lot of activity during work hours :)

That's some pretty impressive analysis, nice visualizations too. Thank you for doing all that hard work!

Yes. While with HTTP pipelining you can request them all over a single TCP connection using a single SSL session, you will need to make an HTTP request for each item you want. If you're on a supported platform, the Firebase SDKs handle all this efficiently and can even provide real-time change notifications.

[Firebase Employee] If you use the SDKs, we handle the connection and all of the data is sent over a reused full duplex socket rather than individual requests. https://www.firebase.com/docs/android/ , https://www.firebase.com/docs/ios/ , https://www.firebase.com/docs/web/

I'm trying to attach a ChildEventListener to the "item" Firebase and I'm getting a "permission denied" error. My guess is that I am doing something wrong, but on the off chance that the adding event listeners is not (yet) enabled, it would be nice to know. Any clues to what I might be doing wrong?

I've never used the Firebase API itself before. It's very clean!

Edit: I reached the same (now obvious) conclusion as mentioned in the reply below. Now my quick hack is working perfectly. Thank you so much for this!

It would be interesting to redo the top karma list by comment karma only. It would also be interesting to look at liberal vs conservative political sentiment over time. I feel like the site has gotten more liberal over the years, especially after all the Chelsea Manning stuff, but not sure if that is accurate.

just wanted to let you know that I love your application!

Thanks! I think you'll like the new version whenever it gets finished :)

It's OT but i couldn't resist! Could you also please add some Material Design Love ? Thanks for making this awesome app opensource.

Cheers

I actually have the list of top users by comment karma: https://docs.google.com/spreadsheets/d/1Ws2VK-UB7IQpVUZgPZ9M...

I also included the number of thread wins (user made comment with highest number of points in a given submission thread) to see if there was any unusual relationship. There wasn't: correlation is 0.89. I ended up not including it in the article because it's long enough as-is. :P

[Firebase Dev Advocate] Glad you're enjoying Firebase! Attaching a listener to the "items" Firebase is disabled. This is because it would send every item from HN to your computer. You'll need to attach a listener to the individual item instead. The "permission denied" error is coming from the security rules on the HN Firebase (https://www.firebase.com/docs/security/quickstart.html). If you're trying to find out what the latest updates are, they're kept in the /updates node (https://github.com/HackerNews/API#changed-items-and-profiles).

Great news! Will require a fair bit of retooling, but, ya know -- omelets, eggs, etc!

I see the topstories query to replace scraping /news: https://hacker-news.firebaseio.com/v0/topstories.json?print=...

And there must be a query to get the newest items instead of the current /newest.

Are there also new equivalents for /active, /best, /classic, /show, and /shownew?

I'll be happy to replace dodgy XPATH parsing with a proper API. Hope we won't lose these other views though!
