This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:

mayra-cabrera

Imagine that you want to erase completely the file under config/secrets.yml from your commits history

Move to the working directory where the config folder is placed

cd dummy/

Run git filter-branch, forcing (--force) Git to process—but not check out (--index-filter)—the entire history of every branch and tag (--tag-name-filter cat -- --all), removing the specified file (git rm --cached --ignore-unmatch Rakefile) and any empty commits generated as a result (--prune-empty). Note that you need to specify the path to the file you want to remove, not just its filename. The previous was taken from Github documentation

git filter-branch --force --index-filter \

mayra-cabrera

Running something like

 bundle install --without nothing 

should clear the cache, not sure if it is recommended though. This is one seems a lot better

 rm .bundle/config

See this issue apparently it was already fix :D

This is a mix between two sources:

• http://www.alfielapeter.com/posts/8-transferring-s3-bucket-contents-between-accounts-with-s3cmd
• and http://blog.techopsguru.com/2011/12/s3-bucket-copying-with-multiple-accounts.html

basically the first resource is great but didn't work for me: I had to remove the trailing "/*" in the resource string to make it work. I also noticed that setting the policy on the source bucket was sufficient. In the end these are the exact steps I followed to copy data between two buckets on two accounts

Basically the idea there is:

• we allowe the destination account to read the source bucket (in the console for the source account)
• we log as the destination and start the copy

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

Chapter 1. Basics

Ruby style programming was built on two simple ideas:

1. Code must be crystal clear
2. Code must be concise

Example:

isaacs

echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
. ~/.bashrc
mkdir ~/local
mkdir ~/node-latest-install
cd ~/node-latest-install
curl http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1
./configure --prefix=~/local
make install # ok, fine, this step probably takes more than 30 seconds...
curl https://www.npmjs.org/install.sh | sh
