Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

If you have only just popped it and the terminal is still open, you will still have the hash value printed by git stash pop on screen (thanks, Dolda).

Otherwise, you can find it using this for Linux and Unix:

git fsck --no-reflog | awk '/dangling commit/ {print $3}'
and for Windows:

Using OTP's observer (appmon replacement) remotely

$ ssh remote-host "epmd -names"
epmd: up and running on port 4369 with data:
name some_node at port 58769

Note the running on port for epmd itself and the port of the node you're interested in debugging. Reconnect to the remote host with these ports forwarded:

$ ssh -L 4369:localhost:4369 -L 58769:localhost:58769 remote-host

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

How I configure my Logitech G502 mouse to make me more productive

I use a "gaming mouse" as my current favorite every-day computer mouse, when I'm not just using the trackpad.

If you're not familiar with it, it's a great computer mouse that has some extra buttons that can be arbitrarily assigned key combos, macros, and various functions.

Recently, I decided to tweak some settings for every day desktop/work use, and I've been quite pleased. Here's a couple things I did:

Middle scroll wheel: left/right tilt
