Capture keyboard and mouse events on Linux

Instructions how to capture keyboard and mouse events and turn them into human readable output.

  1. Run evtest without any argments and see which event device you need to use.
  2. Run the following command for the keyboard events:
evtest /dev/input/event5 | grep --line-buffered 'EV_KEY' | sed -r -e 's/.*\(KEY_/Keyboard: /' -e 's/\), value 0/ - UP/' -e 's/\), value 1/ - DOWN/' -e 's/\), value 2/ - HOLD/'

Example of the output:

Keyboard: Z - DOWN

A copy (for posterity) of Steve Yegge's internal memo in Google about what platforms are and how Amazon learnt to build them

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't really have SREs and they make engineers pretty much do everything,

[Recipe] Delete all your likes/favorites from Twitter

Ever wanted to delete all your likes/favorites from Twitter but only found broken/expensive tools? You are in the right place.

  1. Go to: https://twitter.com/{username}/likes
  2. Open the console and run the following JavaScript code:
setInterval(() => {
  for (const d of document.querySelectorAll('div[data-testid="unlike"]')) {
    d.click()
 }

Using my Canon 70D DSLR camera as a web cam on Linux

You'll need:

  1. Video 4 Linux loopback device kernel module (v4l2loopback) - Source: https://github.com/umlaeute/v4l2loopback (You might find builds in your distro's repos - I'm using Fedora so had to build it myself using https://github.com/danielkza/v4l2loopback-fedora/)
  2. gPhoto2 - this is what allows you to access your cameras live feed over USB - this was available in Fedora's repos.
  3. GStreamer or ffmpeg - this is what lets you stream the output from gPhoto2 into the loopback device.

It's been a little while since I set it all up so I can't remember all of the installation details, which will probably be different for your distro anyway unless you're using Fedora. Apologies if I have forgotten something as wel.

Running the stream
