Rephrased from [WayBack] Jeroen Wiert Pluimers – Google+:
If you install a virtual machine, ensure the disk controller and disks are SCSI based.
This has many advantages, including:
- speed (usually the SCSI drivers can be paravirtualised)
- hot addition of new disks
It holds for virtually any virtualization platform including all non-ancient (less than ~10 year old) versions of:
- VMware (Workstation, Viewer, but I expect this also to work on vSphere, ESXI, Fusion)
- Hyper-V
- KVM (and therefore Proxmox)
- VirtualBox
Based on my notes in the above link and the links below:
Note this isn’t just for Linux guests/hosts: Most guests (including Windows) can do a SCSI bus re-scan and detect new SCSI devices.
The trick here is that the guest must already have a virtual SCSI controller (adding that will require a reboot of the guest).
Then adding a new SCSI disk on that controller from any host (Windows, Mac, ESXi, vSphere) should work fine.

A blog entry since it was hard to find about [WayBack] “Isolated segment – all turns from it are closed” – Google Search as the source reveals not much: no explanation at [WayBack] wme-history/index.html at master · wazers/wme-history · GitHub (A repository containing the pretty-printed index and JavaScript files of the WME to investigate version differences – wazers/wme-history).
Same for [WayBack] “Added big junction” waze – Google Search and [WayBack] wme-history/index.html at master · wazers/wme-history · GitHub
Note that updates you make to the map can take a while to update to the actual live map (even after approval).
You can check at [WayBack] Waze Status for the latest updates.
I added a piece of road in between Thunstetten and Herzogenbugsee, but could not save it:

A long time ago I wrote in Mac/PC: sending Wake-on-LAN (WOL) packets « The Wiert Corner – irregular stream of stuff “I’ve succesfully woken up these machines: HP XW6600 running ESXi 5.1 ThinkPad W701U running Windows 7”.
The XW6600 have now been demoted to Windows 10 machines that I only need every now and then, so most of the time they are shutdown.
However, with the installation of Windows 10 however, they stopped reacting to WOL (Wake on LAN).
Per web-search results, I’ve tried all the permutations of the below settings to no avail.
Luckily, my trusty APC PDU AP7921 (and little sister AP7920) helped out: when setting the “Reboot Duration” to 30 seconds or more (so the power fully drains), it can be rebooted.
Note that since I bought these a long time ago, they have been replaced by these:
- AP7920 Rack PDU, Switched, 1U, 12A/208V, 10A/230V, (8)C13
- AP7921 Rack PDU, Switched, 1U, 16A, 208/230V, (8)C13
Firmwares:
Power usage:
- an XW66000 with 32 gigabytes of RAM and one hard disk takes between 0.6-1.2 Ampère of current, which at 230 Volt is 140-275 Watt.
- over one day that is between 3.4 and 6.6 kWh
Settings tried

Time signatures, a musicians best friend if used wisely. Time signatures when used correctly can add other dimensions to a song, a feeling of awkwardness, incompleteness, shuffling dancing, rushing…
That’s the start of [WayBack] Famous Songs in Slightly Odd Time Signatures – A Guide to Rhythms – The Evil Jam.
It has links to the tracks mentioned (usually as YouTube or Vimeo links) so it is easy to listen back to the marvels using these time signatures.

Two decades before the personal computer, a shy engineer unveiled the tools that would drive the tech revolution
Don’t read this as a historic piece, but as the potential we are still going to experience what was not just sketched by a true visionary in 1968, but also demonstrated back then: [Archive.is] How Douglas Engelbart Invented the Future | Innovation | Smithsonian.
I am including one of the pictures below by Christie Hemm Klok that shows how far Engelbart was ahead of his time: not his initial invention of an input device (the mouse) “chord” kind.
After that, read about his 1968 presentation: The Mother of All Demos – Wikipedia
Finally, watch the video below, well worth watching the more than one and a half hours.

Below is one of the reasons I try to stay on the back-end side of things. Those are complex enough to focus on for me.
[WayBack] I’m harvesting credit card numbers and passwords from your site. Here’s how.
It basically comes down to:
- anything in the same page has access to anything happening on that page.
- be careful when using
npm and ad networks.
- perform security operations in a light-weight iframe that is scrutinized.
The source of any npm package might be different from the source you find in a the underlying repository. This recursively holds for all the other npmit pulls in.

The manual for the CSL Bearware 302658 clock that uses the DCF77 signal is at [WayBack] Bearware_Manual-302658-20161220FZ004.pdf.
I like the relatively large 3.3 inch display and the blue background.
You can get the clock here:

We are in the midst of a cosmic flowering of synchronicity that will remove the barriers to the dreamscape itself.
If you want/need/hate some of this New-Age stuff, then use either of these sources:
To quote the first:
So, what is this for? Put it on your website as placeholder text. Print it out as a speech for your yoga class and see if anyone can guess a computer wrote it. Use it to write the hottest new bestseller in the self-help section, or give false hope to depressed friends and family members.
