“A saddle tower near catenoid limit with no reflection symmetry. This took me >1 month to compute. I now want to take a break from @WolframResearch Mathematica for some weeks.” —Hao Chen 陳浩 @Chen_Hao@twitter.com, 11:45 PM · Jun 29, 2022.

I have no idea what it means, but it looks fascinating.

I think the most futile nerdy thing I've done this year is deliberately switch my language everywhere to en_GB from en_US. That country struck me as so disturbingly crazy to the point I wanted to avoid using American English.

What do you do with your PC for prolonged inactivity?

“Since the introduction of a car-free zone in 2007, the auto mode share in Ljubljana has dropped by 32%.

The concentrations of black carbon emissions has reduced 70% and noise pollution is down six decibels.

Most importantly, it’s a more pleasant place to spend time (and money).” —@modacitylife, [3/3].

“A low-car city is only as good as the infrastructure around it.

Since 2007, Ljubljana has launched a free on-demand electric shuttle service, renovated and built 13 active travel bridges, launched a bikeshare system that makes 900,000 trips a year, and expanded its bus network.” —@modacitylife, [2/3].

“To great uncertainty and controversy, in 2007, Ljubljana closed 12 hectares of its city center to private cars. Just 40% of residents approved.

A decade later, no less than 97% were against reopening to motor traffic: “None of us can really imagine cars ever staging a comeback”.” —Melissa & Chris Bruntlett, @modacitylife, twitter.com/modacitylife/statu, [1/3].

Money corrupts; bitcoin corrupts absolutely.

Disregarding all of bitcoin's shortcomings, a financial instrument that brings out the worst in people—greed—won't change the world for the better.


Having more than one house and/or speculating on similar basic human needs should be illegal.

Diary stuff. 

Picked my first four-number bicycle lock today. Assumed people generally use birthday dates, so that's 19** right off the bat. Then I just “trial and errored” my way down from the nineties assuming it was either their kid's date, or someone around my age, and voilà: 1982. I chuckled and promptly closed the lock again.

“Old Euclid drew a circle
On a sand-beach long ago.
He bounded and enclosed it
With angles thus and so.
His set of solemn greybeards
Nodded and argued much
Of arc and circumference,
Diameter and such.
A silent child stood by them
From morning until noon
Because they drew such charming
Round pictures of the moon.” —Vachel Lindsay

Rant about MS Windows. 

Windows is so f*ing bad it's insane.

→10-year-old laptop + HDD + Linux = usable within a minute.
→10-year-old laptop + SSD + Windows 10 = unusable within five to ten minutes.

Goddamnit sucks.

Just some arbitrary thought. 

I hope cr*pto“currency” dies and takes Elon Musk's “good guy” image with it.

First lead climb on a rock face this weekend; scary, dangerous, but utterly amazing: lizards that walk next to your hands, birds that fly into their nests. It's been years since I experienced something so peaceful.
