How to convince the `pacmixer` AUR package to build

How to convince the pacmixer AUR package to build

When building the package, select cleanBuild, edit the PKGBUILD file and add this code verbatim right before the build() function:

prepare() {
    cd "${srcdir}/${pkgname}-${pkgver}"
    patch -p1 <<'EOF'

Vaccination Status Overview script for VisiData

This VisiData script is meant to take a number of CSV files containing vaccination information and mangle the data to create a nice overview.

The input data is expected in the format seen in the sample files.

To use, just load it with vd -p Vaccination_Status_Overview.vd; to add or remove persons, the script itself needs to be edited.

Update: Refactoring so that the duration until the next refresher shot is calculated and displayed. An additional column in the data files is needed that contains the time to the next refresher in weeks; if that column is empty, that vaccination shot is assumed to be final without any more required refreshers.

Update: Added a colorized version of the overview -- just use Vaccination_Status_Overview-colorized.vd instead of Vaccination_Status_Overview.vd. Dates are displayed in red if the target refresh date has passed, in yellow if the target refresh date is 26 weeks or less ahead, and in green otherwise.

MikroTik failover routing description (living document)

MikroTik Routing Failover

This is meant to be a somewhat-easier-to-digest recap of the discussion that can be found on the MikroTik forum at this URL: https://forum.mikrotik.com/viewtopic.php?f=23&t=157048&p=836497&hilit=failover#p836497 Note that the forum discussion not only addresses failover, but also load balancing at the same time (without explicitly saying so in the beginning).

For the sake of this document, we'll make some assumptions:

Usage

Set up the host to connect to and port base to open:

export HOSTNAME=foo.bar
export JUMPHOST=jumphost.baz
export PORTBASE=1234

Create the autossh user:
