Thank you for building this. I admire the simplicity and elegance. Would be cool if the "Mentioned 2 times at Hackernews" was hyperlinked to the mention. Can this be done?

It will totally be done :)

Next iteration will be on making the navigation better, so that you can click on everything that's possible.

Very useful and damn fast!

As quite a few have asked via the comment form: it's a nginx + passenger + ruby 1.9.2 stack, with solr for indexing, mongodb for data back-end, rails fragment caching in redis, and a warmup script to fill the caches.

That's a great stack. Any reason you went with Redis for the caching instead of memcached?

Well I'm more used to Redis, as I've used more than a couple of times with Resque (job processing in Ruby).

I started the crawler behind HackerBooks with Resque and Redis, but ended up saving some RAM by going back to a simple daemon. I reused Redis to provide the caching.

So well: I mostly used what I was used too.

Definitely makes sense if you're already using Redis for something else.

Sweet domain name. Did you have to shell out a lot for it?

I spent a bit of time on that, I must admit :)

In the end I paid 90$ for 3 years, which is OK I guess.

on that note, hackertext, hackermenu, hackerledger, hackerconventions, hackerelite, hackerplans, hackermanifest, hackerstatement, hackerplay, hackersection, hackervolumes, etc... all seem to be free. (shameless plug for nametoolkit.com - downvote me if you wish ;))

Those who code together, stay together!

Or was it the opposite?

We're going to work together on a SAAS product and became associates (after moving to the countryside).

Wish us luck :) (and communication, it's needed :-)
