“ If your house is flooded or burnt to the ground, whatever the threat to it, let it concern only the house. If there's a flood, don't let it flood your mind. If there's a fire, don't let it burn your heart. Let it be merely the house, that which is outside of you, that is flooded or burned. Now is the time to allow the mind to let go of attachments. ”— Ajahn Chah, "Our real home" from "Living Dhamma"
“ You can't stop the waves, but you can learn to surf. ”— Jon Kabat-Zinn
“— Pipe Logic (by Linus Akesson)Delightfully useless epiphany: Suppose the null-byte is an electron. Then, /dev/zero provides an infinite supply of electrons and /dev/null has an infinite appetite for them. Let's call these devices Vss and Vdd, respectively.
In this model, a UNIX pipe acts like a wire, that is, a conductor with parasitic capacitance. If the pipe is connected to Vss, its pipe buffer in kernel space quickly fills up with null-bytes, and the pipe acts like a negatively charged metal plate. If it is connected to Vdd, the pipe buffer is drained, and the pipe acts like a positively charged metal plate.
[...]
Pipes have flow control: Writes to a full pipe will block, as will reads from an empty pipe. Hence, our MOSFET would need to sense whether a read or write would block, without actually performing the read or write operation. As far as I know, no standard UNIX command can be forced into this role, but we can write such a program from scratch easily enough.
[...]
Using only pipes and our small MOSFET program, we should be able to construct arbitrarily complex digital circuits.

“ If we are to keep the term “capitalism” at all, then, we must distinguish between “free-market capitalism” on the one hand, and “state capitalism” on the other. The two are as different as day and night in their nature and consequences. Free-market capitalism is a network of free and voluntary exchanges in which producers work, produce, and exchange their products for the products of others through prices voluntarily arrived at. State capitalism consists of one or more groups making use of the coercive apparatus of the government — the State — to accumulate capital for themselves by expropriating the production of others by force and violence. ”— Murray N. Rothbard, "Capitalism vs Statism"
