Took me a while to figure out that you can run any command in Atom.io, even if it’s not in the menu or toolbar:
This isn’t very clear in Atom, but what you’re after is this menu item: Toggle Command Palette
Mac OS X: Shift+Command+P:
Windows: Ctrl+Shift+P

There still is no ps xf on Mac OS X.
You need brew install pstree for that. Then you can excute pstree which gives you a treeview of the processes running.

After trying to move an operating system from one disk to another, Proxmox stalled the console and ended up in a really high I/O delay.
These commands helped me finding out what was wrong:
apt-get install iotop
iotop
ps -aux | grep usbbackup
ps -aux | grep rsync
zpool status
lvscan
qm list
qm unlock ###
qm stop ###
Somehow Proxmox was thinking the VM ### was still in use, but on Linux level it wasn’t:
# lvscan
ACTIVE '/dev/pve/swap' [8.00 GiB] inherit
ACTIVE '/dev/pve/root' [27.75 GiB] inherit
ACTIVE '/dev/pve/data' [62.04 GiB] inherit
ACTIVE '/dev/pve/vm-###-disk-1' [40.00 GiB] inherita

Interesting read [WayBack]: The mystery of the Zombie RAM | josh.com that starts with
It all started one bright morning when I wondered: Can the RAM memory on an AVR chip continue to store data after power is removed? If it can hold the data even just for a brief moment, then…
TL;DR: Always watch your uA sources. Or like Lübbe Onken puts it on G+:
In my first company, we had built a piece of hardware, which turned itself on mysteriously sometimes. We found out that this was caused by a status led that created enough current in bright sunlight.

Some notes based on The woods and trees of OpenSuSE on single-board computers – image abbreviations – and getting it installed using OS X « The Wiert Corner – irregular stream of stuff.
I needed to get Ubuntu on an ODROID-C1+ (as it looks like nobody is maintaining a current OpenSuSE for it).
Download either of these (note that “minimal” is different from “mate minimal”; see https://www.youtube.com/watch?v=jOYWx_YToh8) from de.eu.odroid.in/ubuntu_16.04lts:
I installed on a 8 gigabyte SD card that revealed itself as /dev/disk1 using this diskutil command (via osx – List all devices connected, lsblk for Mac OS X – Ask Different [WayBack])
diskutil list
So this wrote the image to SD card in a sudo su - prompt:
targetDevice="disk1"
unxz --keep ubuntu-16.04-minimal-odroid-c1-20160817.img.xz; \
diskutil umount "/dev/${targetDevice}s1"; \
dd bs=1m of="/dev/r${targetDevice}" if=ubuntu-16.04-minimal-odroid-c1-20160817.img; \
sync; \
diskutil list; \
diskutil eject "/dev/${targetDevice}"
Use the default user and password that [WayBack] ODROID Forum • View topic – Ubuntu Minimal User / Password mentions:
odroid login: root
Password: odroid
From there, create a new user and add it to the sudo group (I used visudo to check the correct group for sudoers) :
adduser jeroenp
addgroup jeroenp sudo
And then hook it up to the network and get the IP address:
ifconfig
Now you can ssh into the odroid with user jeroenp and the password assigned to it. You can also perform a sudo su - to get to root level.
First of all, install etckeeper as it’s a life saver:
apt-get install etckeeper
This will install some other packages, but that’s OK; it will end suggesting you to enter email address, name and perform an initial commit:
Initialized empty Git repository in /etc/.git/ *** Please tell me who you are. Run git config --global user.email "you@example.com" git config --global user.name "Your Name" to set your account's default identity. Omit --global to set the identity only in this repository. fatal: unable to auto-detect email address (got 'root@odroid.(none)') etckeeper commit failed; run it by hand
Do that:
cd /etc
git config --global user.email "example@example.org"
git config --global user.name "Example User"
git commit -m "initial commit"
Now perform these steps:
Change root password:
# sudo su -
# passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Disable etckeeper daily autocommits involves one line in /etc/etckeeper/etckeeper.conf:
-#AVOID_DAILY_AUTOCOMMITS=1
+AVOID_DAILY_AUTOCOMMITS=1
Change the hostname; assuming your new host name is newHostName.
/etc/hosts and replace the old hostname with newHostNamehostnamectl set-hostname newHostName
exec bash
hostname -fBoth the command prompt and the hostname output should show newHostName.
Update/Upgrade:
apt-get update
apt-get upgrade
Fix the cursor in console mode:
Somehow the Odroid C1+ does not support a blinking hardware text cursor.

The [WayBack] github.com/openSUSE/susefirewall2-to-firewalld is on my research list as right before going on holiday, upgrading broke my firewall configuration (:
Tumbleweed sometimes means living on the bleeding edge (which forces you to learn new things faster), so I knew things like this could be coming.

[WayBack] Embarcadero just released a patch for RAD Studio 10.2.2. It breaks linking projects with runtime packages, like GExperts, any other IDE expert and probably also most component packages. – Thomas Mueller (dummzeuch) – Google+ in a response to [WayBack] RAD Studio 10.2.2 Tokyo February 2018 Patch available now at https://cc.embarcadero.com/item/30819. This patch for RAD Studio 10.2.2 (build 2004)… – Marco Cantù – Google+.
RSP-19914 (by Thomas Mueller)
Summary
After installing the RAD Studio 10.2.2 Tokyo February 2018 Patch I can no longer compile any project with “Link with runtime packages”.
Error message:
[dcc32 Fatal Error] Project1.dpr(5): E2225 Never-build package ‘vcl’ must be recompiledSteps to reproduce
1. Create a new VCL project
2. Open project options
3. Select Packages -> Runtime Packages
4. Set “Link with runtime packages” to true
5. Close dialog with OK
6. Compile the project
-> Error
You might have noticed that the MVP logo is no longer on the blog. It got revoked because I was too critical. Given releases like the above, I can’t stop being critical in a public way as the internal ways to effectively voice criticism that used to work in the past stopped working a long time ago.
Not just the MVP was revoked, the account to which the MVP was attached got killed without notification. That account also had the tech-partner licenses attached: the ones I used to support Delphi open source projects. Which means I do not have any Embarcadero provided licenses to support open source Delphi projects any more except the ones I own (the most recent ones being Delphi 2007 and XE4).
Many people in the Delphi community even refuse to become MVP because formally the MVPs are not allowed to be be critical publicly. Which means these community members have a limited list of Delphi versions they can use to support and test their open source projects with.
I am glad for the time I could use those licenses to support open Delphi source projects, but alas, that time is over. I still like the concepts of Delphi as those are strong. I don’t like how Embarcadero handles their infrastructure and product quality.
In the next 2 years there will be Delphi posts on my blog as that’s about the depth of the posting queue right now. After that: time will tell. For the last decade or so, I’ve spend more free time supporting Delphi than spending time on paid Delphi projects. That won’t last forever.
For now I’m going on a two week holiday tomorrow after which I will be available for new projects.

Even when keeping a Nutribullet clean, the activators can jam. One day the white lids activating the spinning mechanism were just stuck.
So below are some links that helped resolving it. They come down to get some liquid between the white lids and casing to loosen any staining.
Some people use WD-40, oil, water with vinegar or oil and vinegar. We just used some fairly hot water and a blunt knife to carefully push each white lid down.
I found most of the videos before getting the right search terms and bumping into the other links. For ease of reading, the videos are at the end.
