notes:

• want to try Brackets code editor — can write plugins in JavaScript
• a friend let me try his 3M Optime 105 noise reduction headset,
• pros: works great, doesn't require power, cheap
• cons: doesn't play sound, large
• consider for airplanes and thinking in loud places

my mac has been begging me to upgrade the OS for a while.. I think I'll let it do that..
