Hi G—,

Thanks for getting in touch. I am not interested in working at Uber for a number of reasons, which are probably all-too-familiar to you.

• Labor issues, specifically the abuse of "dependent contractors”

• Lack of transparency around pay, a willingness to change pay out from under drivers (who have very little recourse)

Notes to make IR shield (made by LinkSprite) work in Raspberry Pi 3 (bought from Amazon [1]). 
The vendor has some documentation [2] but that is not complete and sufficient for Raspbian Stretch. 
Following are the changes that I made to make it work.

$ sudo apt-get update
$ sudo apt-get install lirc

# Add the following lines to /etc/modules file
lirc_dev
lirc_rpi gpio_in_pin=18 gpio_out_pin=17

def pronto2lirc(pronto):
    codes = [long(binascii.hexlify(pronto[i:i+2]), 16) for i in xrange(0, len(pronto), 2)]

    if codes[0]:
        raise ValueError('Pronto code should start with 0000')
    if len(codes) != 4 + 2 * (codes[2] + codes[3]):
        raise ValueError('Number of pulse widths does not match the preamble')

Convert sequence of JPEG images to MP4 video

ffmpeg -r 24 -pattern_type glob -i '*.JPG' -i DSC_%04d.JPG -s hd1080 -vcodec libx264 timelapse.mp4

• -r 24 - output frame rate
• -pattern_type glob -i '*.JPG' - all JPG files in the current directory
• -i DSC_%04d.JPG - e.g. DSC_0397.JPG
• -s hd1080 - 1920x1080 resolution

Slower, better quality

What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would
