A few show tricks to find slow queries in mongodb

Enable profiling

First, you have to enable profiling

> db.setProfilingLevel(1)

Now let it run for a while. It collects the slow queries ( > 100ms) into a capped collections, so queries go in and if it's full, old queries go out, so don't be surprised that it's a moving target...

Installing a Gem on Heroku from a Private GitHub Repo

Sometimes you want to use a gem on Heroku that is in a private repository on GitHub.

Using git over http you can authenticate to GitHub using basic authentication. However, we don't want to embed usernames and passwords in Gemfiles. Instead, we can use authentication tokens.

1. Get an OAuth Token from GitHub

First you will need to get an OAuth Token from GitHub using your own username and "note"

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

The aim of this post is to guide the reader through the process of installing ruby 2.0.0 into rbenv with dtrace probes enabled. As rbenv uses ruby-build, which currently downloads and compiles a copy of openssl rather than using the one maintained and updated in homebrew i prefer to use the homebrew one.

Note that you MUST install xcode before installing anything, then install homebrew, and lastly install openssl, via homebrew as follows.

brew install openssl

Next to overcome the fact that OSX doesn't have an openssl ca certificate bundle, use the following brew to create and maintain one using the CA certs stored in your keychain.
