A way to disable a plugin in vim-plug

plug_disable.vim

If your vim distribution uses vim-plug and includes plugins you don't want, or if you want to simply maintain a single set of plugins but disable some on certain machines, this may be for you.

System Design Cheatsheet

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

  1. Clarify and agree on the scope of the system
  • User cases (description of sequences of events that, taken together, lead to a system doing something useful)
    • Who is going to use it?
    • How are they going to use it?
# Defaults / Configuration options for homebridge
# The following settings tells homebridge where to find the config.json file and where to persist the data (i.e. pairing and others)
HOMEBRIDGE_OPTS=-U /var/lib/homebridge
# If you uncomment the following line, homebridge will log more
# You can display this via systemd's journalctl: journalctl -f -u homebridge
# DEBUG=*

## Seems this is still a problem 5 years later after I created this little gist.
## I have long since stopped using OneDrive (luckily), but according to
## comments below, I have added the new path for OfficeFileCache for macOS

Ask HN: Best Linux server backup system?

Linux Backup Solutions

I've been looking for the best Linux backup system, and also reading lots of HN comments.

Instead of putting pros and cons of every backup system I'll just list some deal-breakers which would disqualify them.

Also I would like that you, the HN community, would add more deal breakers for these or other backup systems if you know some more and at the same time, if you have data to disprove some of the deal-breakers listed here (benchmarks, info about something being true for older releases but is fixed on newer releases), please share it so that I can edit this list accordingly.

  • It has a lot of management overhead and that's a problem if you don't have time for a full time backup administrator.
