If the HP Universal print driver cannot automatically retrieve a printer configuration (say SNMP is blocked on the network or disabled on the device) it defaults to monochrome printing (UPD version 5.0 and newer). This can also lead to long pauses while trying to open the printer properties, as it presumably times out while trying to retrieve the data. On the Device Settings tab, click Device Type: Auto Detect to display the drop-down list and then select Color (and also check the duplex setting).

We got a ssd upgrade for a Mac (JetDrive 885) which comes with an enclosure to allow data to be copied to the new drive. This can be done with Disk Utility – as you are cloning the boot drive you need to run this in recovery mode (boot holding cmd – r). Presumably booting from a usb stick would work as well.
Once in disk utility choose the external drive, select Restore and choose to restore from the Macintosh HD. At this point we ran into an issue:

Now I’ve got this working to some extent here are some notes about setting up Jekyll with SVN and Apache:
Server – Debian 9 Stretch, normal command-line only install. Set up system to use email server (campus smarthost in our case).
Install SVN and Apache and set up accordingly.
Install Jekyll:
Create an SVN repository for the site files.
Create new project directories at a temporary location, e.g.

In Debian 9 Stretch Apache is configured to use the systemd PrivateTmp feature by default. This means that the Apache tmp directory actually lives in /tmp/systemd-private-BIGLONGSTRING--apache2.service-STRING.
So if you are running an SVN server that uses Apache for serving, anything written to /tmp in the hook scripts ends up in the private directory rather than the normal userspace one.
Setup – Dell Latitude 7490 running Ubuntu 18.04 Bionic and Dell WD15 USB-C dock.
Problem – system freezes when dock unplugged.
This problem started after updates. The solution found was to revert to the previous kernel (4.15.0-43-generic) from 4.15.0-44-generic. Did this by setting GRUB to remember the boot setting – change /etc/grub/grub with:
GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true
and run
Then hit esc at the loading screen to get to the grub menu.
