Public Markdown Notes

Lately I started collecting my markdown notes worth sharing in a public HackMD book. These will mainly focus on technical ideas or engineering cheat sheets. Also, longer blog posts might be better suited over there.

A collection of all published notes by me.

It Comes Down To Time

Nonautonomous systems are romantic, actually: the state doesn’t just depend on where you are, but when you are.

dx/dt = f(t,x)

Always Coming Home

Arguably one of the most important authors of speculative fiction of the 20th and 21st centuries: Ursula Kroeber Le Guin

Today marks exactly 8 years and 8 days since her death and over 40 years since the publication of her novel, and here I am, stumbling across a section that’s still magical.

“When I take you to the Valley, you’ll see the blue hills on the left and the blue hills on the right, the rainbow and the vineyards under the rainbow late in the rainy season, and maybe you’ll say, “There it is, that’s it!” But I’ll say. “A little farther.” We’ll go on, I hope, and you’ll see the roofs of the little towns and the hillsides yellow with wild oats, a buzzard soaring and a woman singing by the shadows of a creek in the dry season, and maybe you’ll say, “Let’s stop here, this is it!” But I’ll say, “A little farther yet.” We’ll go on, and you’ll hear the quail calling on the mountain by the springs of the river, and looking back you’ll see the river running downward through the wild hills behind, below, and you’ll say, “Isn’t that the Valley?” And all I will be able to say is “Drink this water of the spring, rest here awhile, we have a long way yet to go and I can’t go without you.”

The Latte Art Journey

For this year, I set myself the goal of exploring more silly things and learning new skills solely because they’re fun! Latte art was one idea I decided to try and this is day 29 of that journey:

RANDU

A so called "LGC" (=Linear Congruential Generator) developed by IBM and used primarily in the 1960s and 1970s to generate pseudorandom numbers.

Due to its bad spectral score, Donald Knuth referred to it as being:

"truly horrible"

Hey!

Actually, the movie about Aaron Swartz reminded me that tumblr exists. And that's why I'm here once again.
