Why do so many Internet sites end with the letter ’r’ (but not ’er’)?  Think about Tumblr, Dopplr, Migratr.  What’s behind this?

We just launched a project called lanyrd, which is a play on lanyard. We partly picked the name because the domain was available, but there’s actually a big advantage to using a made-up word: it’s really easy to search for coverage and feedback on Twitter, Google Blogsearch and the like. The string “lanyrd” is almost exclusively used to discuss our project—had we used a dictionary word, tracking down feedback would have been a lot harder.

Who are major competitors to Solr?

ElasticSearch is a really interesting one—it’s the same underlying search library (Lucene) and the same integration model (an HTTP interface) but takes quite a different approach. It hasn’t been around for a long time but it looks very impressive: http://www.elasticsearch.com/

What is the largest production deployment of Server Side JavaScript?

I believe Flickr used to use Rhino for scripting the image processing (resizing, thumbnailing, sharpening) that was applied to every single uploaded photo. No idea if that’s still the case though.

How do Solr, Lucene, Sphinx and Searchify compare?

Lucene is a Java library for creating and searching through a full text index. If you want to make use of it, you’ll need to write your own Java code that integrates with it.

Does SQLAlchemy depend on MySQLdb?

No. SQLAlchemy can talk to all sorts of different DB-API compliant backends, including MySQL Connector/J (Jython only), MySQL Connector/Python, mysql-python (the MySQLdb module) and OurSQL—plus backends for many other databases. See the full list here:

What is the best way to learn about setting up server software for Python based web apps?

In what circumstances should one use “magic quotes” in PHP?

Absolutely never. Magic quotes was a badly designed feature, and PHP has been trying to escape its legacy for years. If you are constructing SQL strings using string concatenation you’re asking for trouble—use prepared statements or a library that interpolates and correctly escapes variables for you.

Which major companies are using Solr for search?

Which Solr app for Django is better: Haystack or django-solr-search (solango)?

I’d go with Haystack—while it supports multiple backends, I get the feeling Solr is the principle backend it was developed for. It’s extremely well documented in my opinion, and the SearchQuerySet API it gives you makes running low-level queries really easy if the higher level class-based view it provides don’t do quite what you want.

The BBC have a pretty big CouchDB cluster, which they use mostly as a replicated key-value store. It’s used by their new identity platform which includes customisation features for iPlayer.

What is the history of Django? I’ve been playing with Quora—it’s a really neat twist on the question-and-answer format, which makes great use of friends, followers and topics and has some very neat live update stuff going on (using Comet on top of Tornado). I just posted quite a long answer to a question about the history of Django.
