Mathematics

To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature. C.P. Snow talked about two cultures. I really think that those two cultures separate people who have and people who have not had this experience of understanding mathematics well enough to appreciate nature once. […] Physicists cannot make a conversion to any other language. If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in. She offers her information only in one form; we are not so unhumble as to demand that she change before we pay any attention.

Control T for TENEX

This magic works via detection of a STATUS control character, Control-T, by the kernel tty driver, which then prints the load line via tty_info() on FreeBSD or ttyinfo_locked() on Mac OS X. It also sends a SIGINFO to the process, so it can run its own routine. See STATUS in the termios(4) man page.

It is so freakin’ cool when I learn new Unix tricks. It’s like a maze of twisty passages, all alike; Except there’s… oh! A piece of candy! oh! A piece of candy! oh! A piece of candy.

Prioritize practical movement

Natural human movement comprises locomotive skills such as walking, running, balancing, jumping, crawling, climbing, or swimming; manipulative skills such as lifting, carrying, throwing, and catching; and combative skills such as striking and grappling. In today’s comfortable world we are losing sight of the practicality of these skills, yet their value cannot be ignored whenever a life-threatening situation arises. You might have to run for your life, or climb, swim, fight, lift, etc. These abilities can save not only your own life, but that of strangers and loved ones as well. George Hebert said, “Be strong to be useful.” Do you want to be strong and useful? Then prioritize practical ways to move.

New knee ligament discovered. Again.

Orthopedic surgeons in Belgium have hunted down the enigmatic structure in cadavers. And what do you know — the good Parisian doctor [who discovered it 150 years ago] was right.

There is an overlooked ligament in the knee. And it might be important for keeping your knee from twisting and turning, especially after an injury to the anterior cruciate ligament, or ACL.
