New Macbook Pro Setup

I'm finally switching to a Macbook Pro as my personal computer after a few months of using one at work. Local development on OSX is a lot easier and bug-free than on a Windows computer.

These gists were really helpful in getting everything set up: (OSX For Hackers) (Clean Install – OS X 10.11 El Capitan Developer Preview 2) (hardening guidelines)

Bluetooth was enabled by default. It's a good idea to turn that off if you're not using it.

In Order to Configure TCP/IP, You Must Install and Enable a Network Adapter Card

If you get this error message, you need to disable and uninstall your network adapter. Once you've done that, you can reinstall the driver to fix it.

Cygwin - Python Compiled Without SSL Support

Download error on unknown url type:
https -- Some packages may not be found!

Docker Run In Crontab

"0 5 * * 1 docker run --rm --name=mycontainer ubuntu:13.10 /opt/bin/job"
The above command is an example of how "docker run" would be used in crontab to run once every week at 5am.

  • --name will name the container and prevent duplicate jobs from running
  • You don't need to use "&" at the end, because crons already run in the background.

MySQL Batch Updates Not Working

Looking at "SHOW PROCESSLIST" and it looks like your queries are running individually instead of in batches like you sent?

This happens because MySQL runs each update statement individually, but you should still be able to see the batches when the queries are in the "init" state.

Use this query to see the batched queries:
