configures then activates gnome-remote-desktop from the command line
#!/usr/bin/env bash
# run this on the remote terminal machine, as auser with sudo powers, probably through a remote ssh shell
# this will overwrite all the settings it touches

How to upgrade [Lenovo] NVMe SSD firmware on Linux

The instructions were tested on a Lenovo X1 Carbon 5th Gen (X1C5) on Arch Linux but should be applicable to other Lenovo models and Linux distributions.

BACKUP YOUR DATA! I created a bootable Ubuntu Image like this:

$ sudo sh -c 'curl --location --silent --fail "http://releases.ubuntu.com/18.04/ubuntu-18.04.1-desktop-amd64.iso" | pv > /dev/<your-usb-drive>'
# note that pv is only there to show progress, it is perfectly fine to redirect curl to the usb drive directly.

then I booted from this drive by pressing F12 on reboot and dumped my NVMe disk to an external hard drive like this:

Falsehoods programmers believe about prices

  1. You can store a price in a floating point variable.
  2. All currencies are subdivided in 1/100th units (like US dollar/cents, euro/eurocents etc.).
  3. All currencies are subdivided in decimal units (like dinar/fils)
  4. All currencies currently in circulation are subdivided in decimal units. (to exclude shillings, pennies) (counter-example: MGA)
  5. All currencies are subdivided. (counter-examples: KRW, COP, JPY... Or subdivisions can be deprecated.)
  6. Prices can't have more precision than the smaller sub-unit of the currency. (e.g. gas prices)
  7. For any currency you can have a price of 1. (ZWL)
  8. Every country has its own currency. (EUR is the best example, but also Franc CFA, etc.)

Amazon Glacier from Python. There's now a branch for this, see here: https://github.com/almost/boto/tree/glacier
# Thomas Parslow http://almostobsolete.net
# Just a work in progress and adapted to what I need right now.
# It does uploads (via a file-like object that you write to) and
# I've started on downloads. Needs the development version of Boto from Github.
#
# Example:
#
# glacierconn = GlacierConnection(AWS_ACCESS_KEY, AWS_SECRET_ACCESS_KEY)
# writer = GlacierWriter(glacierconn, GLACIER_VAULT)
# writer.write(somedata)

# Based on pseudocode from http://stackoverflow.com/questions/742013/how-to-code-a-url-shortener/742047#742047
ALPHABET =
"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".split(//)
