hey, this is Davis.
Want to build something or talk tech, music or art? I'm your man.
I mean, people much, much smarter than me stuck lightning on tiny rocks and made it do complicated math.
Now I get to play lego with it, type incantations from anywhere in the world and make it do incredible things we call software.
What's not to love?`

The Wall
It takes 10,000 hours of practice to achieve mastery; but not all hours are created equal. Instead, add points whenever you practice a skill; visualize them as "bricks" as you build a complete "wall" of 10,000 bricks for that dopamine hit. Works on Windows, Linux and Mac.

Zoho Check-in Chrome Extension
When Covid hit, Zoho became WFH overnight. We were required to use the Zoho People HR app to check in/out. Navigating to the website to do this was a pain. This is a Chromium browser extension to view status and check-in/check-out in Zoho People from any tab in the browser, used by 200+ employees. Was useful till Zoho integrated this feature in their product a few quarters out.

Khartoum v2
A separate assistant app is too much friction: meet the user where they are. So I built an agentic AI assistant to manage all aspects of my life: on WhatsApp! Text it, forward a message, ask questions and dump your tasks. It takes care of the rest. Exposed as a WhatsApp business app, the backend runs on a baremetal server on Hetzner. Setting it up was...fun.

Has the iPod made us anti-social?
It sounds like a dystopian vision. Half of humankind wired up to a parallel universe that leaves them oblivious to their surroundings and fellow man.
The iPod has thus created a minefield over how to behave. "I wouldn't stop someone wearing those white wires to ask for directions. It's like they're putting up a big closed sign" Gordon notes. Many iPod users told him they resented people interrupting their listening to talk to them.
A Muslim juror was discharged from a murder trial after being caught listening to her iPod under the hijab.
When entering a shop, should the user take off their headphones to talk to a sales assistant? Should they take one out? Or leave them both on and turn the volume down?
