The only simple way to do SSH in Python today is to use subprocess + OpenSSH...
#!/usr/bin/python
# All SSH libraries for Python are junk (2011-10-13).
# Too low-level (libssh2), too buggy (paramiko), too complicated
# (both), too poor in features (no use of the agent, for instance)
# Here is the right solution today:
import subprocess
import sys

This script looks for text files in a specific folder that include completed tasks ('@done') and timestamps, and then collects them into a daily log for the Day One journaling application. It works especially well when it's connected to IFTTT. See more details at http://craigeley.com/tagged/sifttter

# Notes:
# * Uses `mdfind` to locate a specific folder of IFTTT-generated text files changed in the last day
# * The location of your folder should be hardcoded in line 67, and the location of your Day One in line 66
# * Scans leading timestamps in each line matching the selected dates
# * Does not alter text files in any way

talk given by John Ousterhout about sustaining relationships

"Scar Tissues Make Relationships Wear Out"

04/26/2103. From a lecture by Professor John Ousterhout at Stanford, class CS142.

This is my most touchy-feely thought for the weekend. Here’s the basic idea: It’s really hard to build relationships that last for a long time. If you haven’t discovered this, you will discover this sooner or later. And it's hard both for personal relationships and for business relationships. And to me, it's pretty amazing that two people can stay married for 25 years without killing each other.

[Laughter]

> But honestly, most professional relationships don't last anywhere near that long. The best bands always seem to break up after 2 or 3 years. And business partnerships fall apart, and there's all these problems in these relationships that just don't last. So, why is that? Well, in my view, it’s relationships don't fail because there some single catastrophic event to destroy them, although often there is a single catastrophic event around the the end of the relation

The Jaunt by Stephen King

Chapter 1

"This is the last call for Jaunt-701," the pleasant female voice echoed through the Blue Concourse of New York's Port Authority Terminal. The PAT had not changed much in the last three hundred years or so - it was still gungy and a little frightening. The automated female voice was probably the most plesant thing about it. "This is Jaunt Service to Whitehead City, Mars," the voice continued. "All ticketed passengers should now be in the Blue Concourse sleep lounge. Make sure your validation papers are in order. Thank you."The upstairs lounge was not at all grungy. It was wall-to-wall carpeted in oyster gray. The walls were an eggshell white and hung with plesant nonrepresentational prints. A steady, soothing progression of colors met and swirled on the ceiling. There were one hundred couches in the large room, neatly spaced in rows of ten. Five Jaunt attendants circulate, speakingin low, cherry voices and offering glasses of milk. At one side of the room was the entranceway, flanked by armed guar

Simple guide for setting up OTG modes on the Raspberry Pi Zero

Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int
