Why I Like Go

I visited with PagerDuty yesterday for a little Friday beer and pizza. While there I got started talking about Go. I was asked by Alex, their CEO, why I liked it. Several other people have asked me the same question recently, so I figured it was worth posting.

Goroutines

The first 1/2 of Go's concurrency story. Lightweight, concurrent function execution. You can spawn tons of these if needed and the Go runtime multiplexes them onto the configured number of CPUs/Threads as needed. They start with a super small stack that can grow (and shrink) via dynamic allocation (and freeing). They are as simple as go f(x), where f() is a function.

FROM pg_stat_activity 
WHERE current_query != '<IDLE>' AND current_query NOT ILIKE '%pg_stat_activity%' 
ORDER BY query_start desc;

-- show running queries (9.2)
SELECT pid, age(clock_timestamp(), query_start), usename, query 
FROM pg_stat_activity 
WHERE query != '<IDLE>' AND query NOT ILIKE '%pg_stat_activity%'

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

Just another quicksort implementation, to see if I memorized the algorithmn.
Apparently, yes. :-)

Gotchas during the implementation:
- forgot to check min and max in the beginning, got IndexError
- choosing nonsense as pivot led me to almost-sorted list (worked when
I stopped being stupid)

GSoC 2012: auth.User replacement

Alex Ogier
Rising Senior, Princeton University

Technical Details

The scope of this project is to break any hard ties to the auth.User model, and allow Django developers to cleanly specify alternate models to be used instead.

Upgrading auth.User - the profile approach

This proposal presents a "middle ground" approach to improving and refactoring auth.User, based around a new concept of "profiles". These profiles provide the main customization hook for the user model, but the user model itself stays concrete and cannot be replaced.

I call it a middle ground because it doesn't go as far as refactoring the whole auth app -- a laudable goal, but one that I believe will ultimately take far too long -- but goes a bit further than just fixing the most egregious errors (username length, for example).

This proposal includes a fair number of design decisions -- you're reading the fifth or sixth draft. To keep things clear, the options have been pruned out and on the one I think is the "winner" is still there. But see the FAQ at the end for some discussion and justification of various choices.
