security and hardening options for systemd service units

A common and reliable pattern in service unit files is thus:

NoNewPrivileges=yes
PrivateTmp=yes
PrivateDevices=yes
DevicePolicy=closed
ProtectSystem=strict

# FontInstaller (by @olemoritz)

# This script installs a custom TTF font on iOS (system-wide).
# It can be used in one of two ways:

# 1. Simply run it in Pythonista, you'll be prompted for the URL of the font 
#    you'd like to install (if there's a URL in the clipboard, it'll be used by default)

# 2. Use it as an 'Open in...' handler, i.e. select this file in Pythonista's 'Open in...
#    menu' setting. This way, you can simply download a ttf file in Safari and open it in

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

• From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
• That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost

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.)

########## SETTINGS 

# On startup, lftp executes ~/.lftprc and ~/.lftp/rc. You can place aliases and 'set' commands 
# there. Some people prefer to see full protocol debug, use 'debug' to turn the debug on.

# Certain commands and settings take a time interval parameter. It has the format Nx[Nx...], where N is time amount
# (floating point) and x is time unit: d - days, h - hours, m - minutes, s - seconds. Default unit is second. E.g.
# 5h30m or 5.5h. Also the interval can be 'infinity', 'inf', 'never', 'forever' - it means infinite interval. E.g.
# 'sleep forever' or 'set dns:cache-expire never'.
