- My 'lab notebook', a la @nelhage's post [1] is markdown-ish, mostly bullet points.  One file per day, stored in git 
  dropbox; I have bash aliases to cd to the appropriate directory and to create a new day's file. I use vim; other editors
  are fine as long as there's minimal 'weight'; you want to make this notebook as low-friction as possible to encourage use.
- Contents tend to be what I worked on that day (bugtracker links when appropriate; a one-liner when not
  [like 'investigated foo library for bar project']).  2nd/3rd level bullets expand - thoughts/reactions when doing
  research, hypotheses that did/didn't pan out if debugging [2], details of on-call response if I've been paged.  Decisions
  made, whether by me alone ("I'll use this pattern here"), by others ("product says ...") or by a group ("we met today and
  agreed to switch to using [mumble]"). Things I learned today.
- Some of this content ends up getting duplicated for
  others' consumption elsewhere - outage retrospective, design decisio

(Context: longer reply to the tweet thread at: https://twitter.com/Lollardfish/status/687807074416234496)

I tend to favor participatory design (your phrasing) and the practical ... in this space, I see product design as fitting into 3-4 levels. (Actually a spectrum; they subdivide further and the boundaries are hard to distinguish. Categorical perception, of a sort.) Gonna talk about this in terms of wheelchair tech, but it applies to other tech, both assistive- and not.

1. The only barrier is "not on the market". "A wheelchair like my current one, but it should have USB power to charge my phone, the joystick should display the date (in addition to the time it currently has), and its throttle should range from current-minimum to twice current-maximum." This product is not really novel,

This uses two containers - one running apt-cacher-ng, and one running rawdns. In fact, this gist is mostly based on the apt-cacher-ng hack documented the rawdns repo.

This includes a few quirks for OS X, which I'll make note of.

1. Edit ('create') /etc/rawdns.json to look like the rawdns.json in this gist.
2. Run a rawdns container: docker run -d --name rawdns -p 53:53/udp -v /var/run/docker.sock:/var/run/docker.sock -v /private/etc/rawdns.json:/etc/rawdns.json:ro tianon/rawdns rawdns /etc/rawdns.json. Note that this references /private/etc/rawdns.json; this is because on OS X, /etc is symlinked to /private/etc, and you can't mount a symlink.
3. Update your DNS resolver to use 127.0.0.1! Assuming OS X, this is in the Network preference pane, behind Advanced -> DNS.
4. dig dns.docker should now include SERVER: 127.0.0.1#53(127.0.0.1).
5. Ru
