Sync-models - Michael P Jung

The basic idea is to synchronize object graphs (for instance messages on a bulletin board) in realtime from the server to the client. Pushing with long polling, perhaps they’ll move to sockets later.

The ingredients: django, gevent, “simple javascript inheritance” by John Resig, knockout.js.

He uses it for a game: http://kodexgame.com/beta/ .

VIM introduction - Gregor Müllegger

Performance matters! In software, but also while coding. So also give your text editor some love!

He loves VIM.

Learn the cursor movement commands for start/end line/word/sentence/paragraph. Same for selection. Get your editor to understand the languages you work with (html, python, etc).

Nice VIM feature: you can pipe the current selection through a unix command and paste it automatically back in. He demonstrated it with uniq to filter out duplicates.

Get completion of words to work.

Look at http://www.vim.org/scripts for scripts to extend VIM with.

He’s got his dotfiles on github, so also look there for his vim config files.

(Obligatory note: I use emacs, hah! But his points are super valid. And I need to check if emacs can do that pipe-your-selection-to-unix trick!)

CBV tab based navigation - Danilo Bargen

He made a tab based navigation with a class based view (CBV). django-tabination gives you a TabView class, you can create your tabs with this.

You can then hook them up into a tab bar navigation. Sprinkle on some css and you’re done.

Because CBVs are classes, you can make subclasses that behave in a different way. Tabs that are hidden. Default tabs. Tabs that first check if you have permission to see them. And so on.
