Remember this? For those too young to remember, it is a rotary dial phone, and I assume many young people wouldn't even know how to use it. To dial a number, you looked up the phone number in a telephone directory (or your little black book), picked up the handset, pushed your finger into the [...]
I had to apply a tiny fix to Net::CouchDB as it was croaking with an error when attempting to submit new documents to a CouchDB 1.0 installation. The error message was
Unknown status code '415' while trying to operate on many documents. POST request to http://127.0.0.1:5984/db/_bulk_docs: Content-Type must be application/json

Services in the cloud are great, and I make some us of them when I find them appropriate or particularly useful. One of the cloud services I've used with some frequency is the del.icio.us bookmarking service, because I can access the bookmarks from any location.

I'm not going to delve too deeply into PowerDNS here because I discuss it very thoroughly in chapter 6 of my book Alternative DNS Servers. So, in other words, if you're not familiar with [...]
Do you want to quickly experience CouchDB's powerful replication? Jan Lehnardt, one of the people behind CouchDB, announced yesterday that he'd made a copy of the very good book Pro Git available as a CouchDB Application (a CouchApp). There are two ways you can go about getting that:
Follow his instructions on getting the app with [...]
I'm revisiting the proof of concept I whipped up the other day (inspired by this) regarding storing DNS zone data in a CouchDB database, because I was perverting the concept of a document database, using my old-school relational model: I had one document per DNS resource record.
What I should have done in the first place, [...]
