@fuadsaud, @jcrawford we do support code fences ```ruby now. If code is wrapped in a fence no indentation is required. Also if you use @xxx where xxx is a coderwall username, it will link to their profile.

Good tip. Probably want to change:

List humans = new ArrayList<Human>();

to

List humans = new ArrayList<Human>(counter);

more efficient because their won't be array reallocation as you go through the loop since size is known.

and you can embed them:

Great tip! really reduces deployment times. Only if I could figure out how to put /assets in .slugignore for heroku deployments where assets will be synced to S3/CDN, that would make life heaven.

great looking log. I had to wrap it in double quotes:

git config alias.lg "log --color --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit --"

Felix, we listened. It's fixed :)

Great reference. another trick is if you select a block of code and press the Tab button it will automatically prepend the 4 needed spaces before every line. happy coding!

I had to use single quotes but works great:

git log --graph --date-order -C -M --pretty=format:'<%h> %ad [%an] %Cgreen%d%Creset %s' --all --date=short

another way (posted on HN):

@tomwrong looks like you had initially published the object sizing code. I want to make sure to give you the credit for it:
http://stackoverflow.com/questions/1248302/javascript-object-size/11900218#11900218

@timpietrusky @html5web there is a shortcut for indenting code by 4 spaces to enable highlighting: you can select your code segment and press tab, it will automatically add 4 spaces in front of every line in the block

Great tip. Prints in descending order of size the largest tables:

relation | size (data) | tablespace | location
-----------------+-------------------+-----------+----------
public.facts | 247 MB (154 MB data) | |
public.sessions | 177 MB (111 MB data) | |
public.follows | 110 MB (42 MB data) | |
public.user_events | 58 MB (47 MB data) | |
public.skills | 41 MB (31 MB data) | |

Good tip. On mac OSX you can do:

dtruss -p <pid>
