PostgreSQL hello world — Electric Clojure

How do I integrate a SQL database backend?

Easy:

• make an ordinary Clojure function query-pokemon-list for the query
• The query is blocking, and Electric Clojure is async, so use e/offload to move it to a thread pool.
  • (Don't block the event loop!)
• e/offload throws Pending until the query finishes, and then the exception "goes away"

curl -I -k "https://api.github.com/repos/:owner/:repo/commits?per_page=1" | sed -n '/^[Ll]ink:/ s/.*"next".*page=\([0-9]*\).*"last".*/\1/p'

### And that's all !
# I saw many fighting with finding first commit SHA or similar fancy thing.
# Here we just rely on the GH API, asking commits at 1 per page and parsing the last page number in the header of the reply (whose body only holds the last commit !)
# So this is robust and bandwidth efficient. :)

# If one want the commit count of a specific SHA, just use :
curl -I -k "https://api.github.com/repos/:owner/:repo/commits?per_page=1&sha=:sha" | sed -n '/^[Ll]ink:/ s/.*"next".*page=\([0-9]*\).*"last".*/\1/p'

# Without this fix, downgrading from Rails 4 to Rails 3 causes session cookies to blow up.

# The way the flash is stored in the session changed in a backwards-incompatible way.

;; Datomic uses immutability to make read queries come from in-app process instead of network. 
;; Web service backed by datomic can have same performance characteristics - browser ajax read 
;; queries can come from in-browser. Changes browser programming model - can code as if all data 
;; is local. Removes all read-IO from browser apps. Components that do IO can now compose. 
;; Still ACID & relational queries like datomic.
