58 bytes of css to look great nearly everywhere

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

Easy way in Bash to check that a binary is installed.
#!/bin/bash
# Exit on the first command that returns a nonzero code.
set -e
# Function that checks if a given executable is on the path. If it isn't, prints an install message and exits.
# Usage: check_binary EXECUTABLE_NAME INSTALL_MESSAGE
check_binary() {
if ! which "$1" > /dev/null; then
# Using a subshell to redirect output to stderr. It's cleaner this way and will play nice with other redirects.

One simple example of a 10u/13node hardware private cloud infrastructure. Built specifically for colocation, based on how datacenters often slice up their racks (e.g. 10u/quarter rack is very common). Saves a few hundred thousand dollars over AWS in three years time. Replace/repeat at that time and then put these into a Hadoop cluster or somethi…

This chassis houses up to 8 processing nodes. Each node is roughly equivilent to 30 elastic compute units. You can scale as needed by building and slotting more nodes into the chassis. Candidates for these nodes includes: app servers of any kind, ssl termination/reverse proxies, cache servers, distributed/concurrent processing, cron jobs, etc.

Barebone:
