How to find out which process is listening on a certain point on my mac. I'm often switching between projects, and have a server from another project running on a port that I now need for another server.

And it looks like Heroku's CLI doesn't always stop all processes correctly when you stop it using ctrl+c

Add a column? Huh? What???

• Converting Array<->List in Java*. Been coding Java for 6+ years and still don't care to learn/memorize this.

• Objective-C block syntax

• bash test format and flags

• vim macro create and execute

I noticed I could never remember these, so I always make aliases, shell functions, or short ~/bin/ scripts for them instead:

• tar: xkcd.com/1168/

• netstat flags (other than "-tulpn" which I have memorized as "tull-pin" like "Tolkien")

• ssh tunnel syntax

Edit: *in one-line.
Array to list:

String[] array = ...;
List<String> immutableList = Arrays.asList(array);
List<String> mutableList = new ArrayList<String>(Arrays.asList(array));

List to array:

List<String> list = ...;
String[] array = list.toArray(new String[list.size()]);

Clear as mud...

RAILS MIGRATION

Regex. While I understand how it works and how it can be used, it's difficult for me to memorize the right regex that should be used at every point. So I just google whenever I want to make use of it. :)

For me it's "manually start postgresql"

Every once in a while my postgres server isn't running and I know to punch that into my browser and land on this Stack Overflow question, where I proceed to copy this command into my terminal:

pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start

It happens infrequently enough that I never bother to alias it or remember how to type it out. I just remember what to Google.

How to "unignore" files with git... Here is a nice and short way.

I would be responsible for 95% of hits coming from google search into the Tutorialpoint's html5 minimal template. Now I could easily type it in every time I set up a new page, but it is now a matter of extreme laziness I think.

This is stupid but g++ compiling filename and output order in the terminal. I've been doing it for four years now and still failing to remember.

ln -s [source] [destination] or ln -s [destination] [source] ?
find . -name [...] -exec grep '...' {} \;

And of course sed, awk and more generally shell syntax (if, loops, switch, etc).
