Yep, we already have basic support for versioning. The foundation of our approach is to have a versioned, documented schema shared among clients. Every write down to the individual…

Yep it's a bummer - this is discussed in a comment below.

I totally agree re: copy-paste. I wasn't clever enough with CSS to do this straight away but it's high on my list: https://github.com/mmcgrana/gobyexample/issues/12 . Also agree th…

Great feedback - thanks. Georgia also works well on Mac, so I just shipped this as the default.

Yeah there is more work to do on explaining slices for sure. I'll probably create a separate example to explain underlying arrays + capacity and perhaps break out the slicing opera…

I'm exploring Go most actively right now. Go solves some problems that I care a lot about - systems access and process composition - for which Clojure isn't as directly designed. C…

I'd love to see a fork of adder that used Ring+Enlive+Moustache.

Ring is a lower-level library than Compojure. It provides a variety of common web-related utilities that will be needed by many Clojure web developers, regardless of what higher-le…

Right, there are actually two potential problems here: 1) the initial compaction takes a long time and there are a correspondingly large amount of buffered writes to append and 2) …

Yes; the current version of FleetDB is designed for datasets that fit in RAM.

The database and metadata are not locked during compaction, at least to the extent that you seem to think they are. When a compaction is requested, the compact query enters the wri…

That's a good question; indeed the index maps just contain pointers back to the records.

Clojure is very compelling for implementing a main-memory database; if you use the persistent data structures and concurrency primitives in the right way, you get atomicity, consis…

SoftLayer offers SSD options on their monthly dedicated servers, in particular 32 & 64GB "Intel SLC SSD" drives.

I'm not familiar with CL's "PROGV", but you can indeed dynamically rebind vars at runtime with Clojure: http://paste.lisp.org/display/73551
