I’m building some projects to slow the internet down. 1. A less addictive Hacker News ( https://hackerdaily.io ) 2. A brief overview of yesterday’s world events ( https://abriefhistoryofyesterday.com )

#2 is fantastic. I would love for it to be even slower. Something like a brief overview of last week, or last month. I can't news I've read yesterday, which means most it was pointless.

https://categorybooks.com

A way to find books by different categories (by prizes their authors have won).

I gave up on the site after a month or two (and a lot of work), but I'm putting some more effort into it again. It's the first website I've ever built, so any feedback is appreciated!

For example, browsing through the books by "people" and by "books", the format is inconsistent and I'm not sure which is considered better design (hovering over the card vs the name to activate). Also apologies ahead for it loading all of the images and having no pagination.. Like I said, first website!

I'm building a quadruped robot a-la Boston Dynamics/MIT Cheetah. I'm not really happy with the state of legged robots in terms of affordability and performance. I've found there are two classes of robots; robots in the first sacrifice mobility for the sake of driving cost down, either limiting the legs to move in a single plane, or using lower cost, but extremely slow servo motors [1][2][3][4]. Robots in the second class don't compromise the performance of the robot, but cost at the very least $6000 [5][6][7]. I'm working on using an underactuated leg (3 degrees of freedom, but only 2 actuators instead of the typically used 3) to bring the cost down, as actuators are the largest cost center for these robots. It should also (hypothetically) have better performance than other robots which use 2 actuators per leg but constrain them to a single plane.

https://www.carboninterface.com ----- Carbon Interface is an API to generate carbon emissions estimates. Right now my API can calculate emissions for flights, driving, shipping and electricity generation. In addition to making the estimates more robust, I am working on having the algorithms behind the estimates certified by international bodies to increase the trust of my API.

An app to help couples learn each other's languages ( https://learncoupling.com ) My wife is Chinese, and I've been learning Cantonese and Mandarin off-and-on on my own for years. For many reasons, I recognize it's extremely difficult to make it work to acquire a language with the help of a romantic partner. I even had a friend who's wife was a doctorate in French language education but completely failed to use her a…

I love the teacup mascots with the "refilling each other" visual. Nice touch.

A few things.

An implementation of bitfunnel search in Go which I plan to put into searchcode.com at some point once I get all the issues resolved and if performance is acceptable

A command line search tool which brute forces with search ranking https://github.com/boyter/cs/ mostly for code but works pretty well for other things as well

Atlassian Confluence Cloud plugins. Mostly out of personal interest and because there appears to be a good marketplace to produce mostly passive income there.
