  • GenX, Millennial? "Meet the Perennials. We are ever-blooming, relevant people of all ages who live in the present time, know what’s happening in the world, stay current, and have friends of all ages. We get involved, stay curious, mentor others, are passionate, compassionate, creative, confident, collaborative, global-minded, risk takers who continue to push up against our growing edge. We comprise an inclusive, enduring mindset, not a divisive demographic." tldr; smart and interesting.

Quick Update

Simplicate and add lightness...

  • Week of 14-20 January.
  • This post is late - I think it's because I was never in the mood to blog over the last few evenings.
  • Monday, walked to the office, omelette at Knead, sunset audio book walk, watched Star Trek Beyond again, time well spent.
  • Discovered PureOS and Purism. That phone looks cool.
  • Tuesday, work, gym, swim, sauna, lunch at Mary-Anne's again - broc fix, work, nap, pipetrack hike with Nick, wagu biltong, sunset audio book promenade walk, browsed photos from ten years ago - found some photos from around 2009 - I met Paul around that time, also first trance party I went to with Andrew.
  • You're Gonna Make Me Lonesome When You Go - Madeleine Peyroux - earworm from 2009 days, I really loved this song for some reason.
  • Homo Deus is a great book. 15 hours well spent. You really need to hear his ideas of the future - especially the Dataism ideas.
  • IPv6: enabler of the 2nd phase of the dataism religion. When everything connects.
  • Uber drivers are training the AI that will replace them.
  • Suffering is optional.
  • Wednesday, work, dev meeting, lunchtime walk, data fixing, a drink at The Hotel on the Promenade, supper at Rafeal's Lebanese Cafe.
  • Thursday, work, gym, swim, sauna, veggie food - broc fix, worked at La Vie, a long promenade walk with Al - chats about health hacking.
  • No Wolfkop this year. Tiny bit worried it's getting rather big.
  • Friday, Naulene made it onto my todo list - fun and games visiting the Cape Town magistrates court, and then the Somerset West magistrates court, breakfast at Fred and Max, back to the magistrates court, then to the police station, gym visit - to write an email to family advocate and lawyer, fetched Mia from school and spent two hours with her at Lourensford, dropped Mia off at her gran's, back to Laurensford's night market with Dirk, good catch up.
  • Why all the court and police activity? Because Naulene, in all her wisdom, has preveted me from seeing Mia all December.
  • Saturday, woke up in Somerset West, braai and nerdy chats with Dirk, braved Somerset Mall to get some AirPods - late xmas present from me to me, a few beach walks: Llandudno, big and little Beta beach, Clifton 1-4 and back, sunset promenade walk, in bed early.
  • AirPods mini-review: pretty cool, 5 hours battery life might be a problem for longer walks, it's a bit annoying that you can't change the volume (by just using the AirPods) - but I worked out that you can use your Apple watch digital crown to change the volume. The double tap thing works ok - I don't use Siri, but you can set it to pause/play and have skip to next track functions. Not having cables that keep getting tangled is amazing though. The trick seems to be to remember taking the little case with you... which kinda complicates your life a tiny bit.
  • Yeah, well spotted, this is a failure on the simplicate principle. Argh.
  • Remember the days you would listen to podcasts on an iPod? Feels like at least two lifetimes ago.

  • Check out: This week in startups podcast.
  • I'm excited for Sivers' next books.
  • Tune of the week: A-ha Unplugged 2017 - I´ve been losing you

Have a fun week, crazy kids.

  • "People feel bound by democratic elections only when they share a basic bond with most other voters. If the experience of other voters is alien to me, and if I believe they don’t understand my feelings and don’t care about my vital interests, then even if I am outvoted by a hundred to one, I have absolutely no reason to accept the verdict. Democratic elections usually work only within populations that have some prior common bond, such as shared religious beliefs and national myths. They are a method to settle disagreements between people who already agree on the basics." -- Yuval Noah Harari, Homo Deus: A Brief History of Tomorrow

  • The narrating-self and experiencing-self can be in conflict, and often are. Why your new diet fails.

SSH Key Management

I did some annual SSH key housekeeping this week. Here are a few things you should probably do:

  1. Use the newer ed25519 keys, update them once a year
  2. Generate a key for each general use case / project
  3. Don't be a muppet and have ssh keys in plain text on your laptop and in your backups
  4. Create a .ssh/config file, which points to your keys on an encrypted filesystem, which does not get mounted at boot time

Below are a few commands and examples to get you started.

Generate an ed25519 key, with your email address as a comment and save it to a key file for a project or company or some use case you might have:

ssh-keygen -t ed25519 -C '' -f swimgeek

Create an ssh config file for your keys and various servers, with user account, port and where the key lives.

Create a .ssh/config file

Host swimgeek-myserver
    Port 2345
    User joe
    IdentityFile /Volumes/crypt-fs/ssh/swimgeek

Host projectabc-prod
    Port 2567
    User root
    IdentityFile /Volumes/crypt-fs/ssh/projectabc

Note that these keys are not in your home directory. They live on an encrypted filesystem, which is not mounted at boot time, and not backed up in plain text.

Install mosh and add an alias to your .zshrc

alias moshprod="mosh projectabc-prod"

  2. Clean energy and greatly improved energy storage
  3. Carbon sequestration at scale
  4. Clean up the oceans
  5. Replace the University, vocational training with status

  7. Cost efficient housing at scale
  8. Constant realtime health monitoring and telemetry
  9. Effective treatments for cancer, diabetes, heart disease
  10. Figure out the human microbiome
  11. Alternatives to paid labour for humans - getting around the need to be needed
  12. Distributed living, ways to live outside big cities, smart towns
  13. Fibre internet to every home and business on the planet
  14. Re-decentralisation of the internet, and tech independence
  15. IPv6 everywhere and interplanetary internet
  16. Optical routing - silicon photonics
  17. Very high quality telepresence - no need to commute
  18. Some new way to stimulate startup innovation and generate more founder run small businesses, possibly fully automated, without employees
