I am too easily distracted. Sitting at my desk on an average day, I have movies,
TV shows, and YouTube videos, about a million different chat applications, my
email client, Steam, and a web browser with yet more chat apps plus social media
all within a couple keystrokes' reach. Along with whatever primary task I've set
out to do, I /also/ have a really chaotic brain and about a million other tasks
bouncing around in it.
Putting all of this together results in terrible productivity and incessant
procrastination If my primary task is something I'm less-than-motivated to
accomplish.
In a recent episode of /The Art of Manliness/, Brett McKay interviews Dr. BJ Fogg
about his new book, /Tiny Habits: The Small Changes That Change Everything/. One
of Dr. Fogg's statements in this episode stuck with me; when training yourself
to adopt new behaviours, there are three things that must factors that determine
your success: motivation, ability, and a prompt. A prompt is just something that
reminds you of the behaviour you're trying to adopt. The act of brushing your
teeth might be the prompt for flossing. The act of flossing might be the prompt
for making coffee. In my situation, the prompt is just needing to get work done
so we'll ignore that factor. Ability refers to how simple you find the task and
motivation is how motivated you are to accomplish it. These last two must
balance each other out; if your motivation to complete the task is low, your
ability must be high — the task must be easy, while if your ability is low, your
motivation must be rather high.
*** Notes
- Close primary browser with a million tabs open and use Epiphany
- Close all the chat apps
- Disable notifications/enable Do Not Disturb mode on /both/ your phone /and/
computer
- Take off your smart/fitness watch
- If you listen to music, make it something calming, not eclectic

One of the things many of us struggle with when setting friends and
family up with Linux is remote support. Commercial solutions like
[[https://www.realvnc.com/][RealVNC]] and [[https://rustdesk.com/][RustDesk]] do exist and function very well, but are often more
expensive than we would like for answering the odd "I can't get Facebook
open!" support call. I've been on the lookout for suitable alternatives
for a couple years but nothing has been satisfying. Because of this, I
have held off on setting others up with any Linux distribution, even the
particularly user-friendly options such as [[https://linuxmint.com/][Linux Mint]] and [[https://elementary.io/][elementary OS;]]
if I'm going drop someone in an unfamiliar environment, I want to be
able to help with any issue within a couple hours, not days and
/certainly/ not weeks.

[[https://linuxunplugged.com/421][Episode 421 of LINUX Unplugged]] gave me an awesome idea to use [[https://github.com/slackhq/nebula][Nebula,]] a
networking tool created by Slack, [[https://libvnc.github.io/][X11vnc,]] a very minimal VNC server, and
[[https://remmina.org/][Remmina,]] a libre remote access tool available in pretty much every Linux
distribution, to set up a scalable, secure, and simple setup reminiscent
of products like RealVNC.

*** Nebula
The first part of our stack is Nebula, the tool that creates a network
between all of our devices. With traditional VPNs, you have a client
with a persistent connection to a central VPN server and other clients
can communicate with the first by going through that central server.
This works wonderfully in most situations, but there are a lot of
latency and bandwidth restrictions that would make remote support an
unpleasant experience. Instead of this model, what we want is a /mesh/
network, where each client can connect directly to one another /without/
going through a central system and slowing things down. This is where
Nebula comes in.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
In Nebula's terminology, clients are referred to as /nodes/ and central
servers are referred to as /lighthouses/, so those are the terms I'll use
going forward.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
Mesh networks are usually only possible when dealing with devices that
have static IP addresses. Each node has to know /how/ to connect with the
other nodes; John can't meet up with Bob when Bob moves every other day
without notifying anyone of his new address. This wouldn't be a problem
if Bob phoned Jill and told her where he was moving; John would call
Jill, Jill would tell him where Bob is, and the two would be able to
find each other
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
With Nebula, nodes are Bob and John and Jill is a lighthouse. Each node
connects to a lighthouse and the lighthouse tells the nodes how to
connect with one another when they ask. It /facilitates/ the P2P
connection then /backs out of the way/ so the two nodes can communicate
directly with each other.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
It allows any node to connect with any other node on any network from
anywhere in the world, as long as one lighthouse is accessible that
knows the connection details for both peers.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
**** Getting started
The /best/ resource is [[https://github.com/slackhq/nebula][the official documentation,]] but I'll describe the
process here as well.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
After [[https://github.com/slackhq/nebula#1-the-nebula-binaries-or-distribution-packages-for-your-specific-platform-specifically-youll-need-nebula-cert-and-the-specific-nebula-binary-for-each-platform-you-use][installing the required packages,]] make sure you have a VPS with a
static IP address to use as a lighthouse. If you want something dirt
cheap, I would recommend one of the small plans from [[https://buyvm.net][BuyVM.]] I do have a
[[https://my.frantech.ca/aff.php?aff=3783][referral link]] if you want them to kick me a few dollars for your
purchase. [[https://www.hetzner.com/cloud][Hetzner]] (referral: ~ckGrk4J45WdN~) or [[https://www.netcup.eu/][netcup]] (referral:
~36nc15758387844~) would also be very good options; I've used them all and
am very comfortable recommending them.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
**** Creating a Certificate Authority
After picking a device with a static IP address, it needs to be set up
as a lighthouse. This is done by first creating a Certificate Authority
(CA) that will be used for signing keys and certificates that allow our
other devices into the network. The ~.key~ file produced by the following
command is incredibly sensitive; with it, anyone can authorise a new
device and give it access to your network. Store it in a safe,
preferably encrypted location.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC bash
nebula-cert ca -name "nebula.example.com"
#+END_SRC
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
I'll explain why we used a Fully-Qualified Domain Name (FQDN) as the
CA's name in a later section. If you have your own domain, feel free to
use that instead; it doesn't really matter what domain is used as long
as the format is valid.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
**** Generating lighthouse credentials
Now that we have the CA's ~.crt~ and ~.key~ files, we can create and sign
keys and certificates for the lighthouse.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC bash
nebula-cert sign -name "buyvm.lh.nebula.example.com" -ip "192.168.100.1/24"
#+END_SRC
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
Here, we're using a FQDN for the same reason as we did in the CA. You
can use whatever naming scheme you like, I just prefer
~<vps-host>.lh.nebula...~ for my lighthouses. The IP address can be on any
of the following private IP ranges, I just happened to use ~192.168.100.X~
for my network.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
| IP Range | Number of addresses |
|-------------------------------+---------------------|
| 10.0.0.0 10.255.255.255 | 16 777 216 |
| 172.16.0.0 172.31.255.255 | 10 48 576 |
| 192.168.0.0 192.168.255.255 | 65 536 |
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
**** Creating a config file
The next step is creating our lighthouse's config file. The reference
config can be found in [[https://github.com/slackhq/nebula/blob/master/examples/config.yml][Nebula's repo.]] We only need to change a few of
the lines for the lighthouse to work properly. If I don't mention a
specific section here, I've left the default values.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
The section below is where we'll define certificates and keys. ~ca.crt~
will remain ~ca.crt~ when we copy it over but I like to leave the node's
cert and key files named as they were when generated; this makes it easy
to identify nodes by their configs. Once we copy everything over to the
server, we'll add the proper paths to the ~cert~ and ~key~ fields.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC yaml
pki:
ca: /etc/nebula/ca.crt
cert: /etc/nebula/
key: /etc/nebula/
2021-05-16 05:08:58 +00:00
#+END_SRC
2021-12-04 23:11:39 +00:00
The next section is for identifying and mapping your lighthouses. This
needs to be present in /all/ of the configs on /all/ nodes, otherwise they
won't know how to reach the lighthouses and will never actually join the
network. Make sure you replace ~XX.XX.XX.XX~ with whatever your VPS's
public IP address is. If you've used a different private network range,
those changes need to be reflected here as well.
#+BEGIN_SRC yaml
static_host_map:
"192.168.100.1": ["XX.XX.XX.XX:4242"]
2021-05-16 05:08:58 +00:00
#+END_SRC
2021-12-04 23:11:39 +00:00
Below, we're specifying how the node should behave. It is a lighthouse,
it should answer DNS requests, the DNS server should listen on all
interfaces on port 53, it sends its IP address to lighthouses every 60
seconds (this option doesn't actually have any effect when ~am_lighthouse~
is set to ~true~ though), and this lighthouse should not send reports to
other lighthouses. The bit about DNS will be discussed later.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC yaml
lighthouse:
am_lighthouse: true
serve_dns: true
dns:
host: 0.0.0.0
port: 53
interval: 60
hosts:
#+END_SRC
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
The next bit is about [[https://en.wikipedia.org/wiki/Hole_punching_%28networking%29][hole punching]], also called /NAT punching/, /NAT
busting/, and a few other variations. Make sure you read the comments for
better explanations than I'll give here. ~punch: true~ enables hole
punching. I also like to enable ~respond~ just in case nodes are on
particularly troublesome networks; because we're using this as a support
system, we have no idea what networks our nodes will actually be
connected to. We want to make sure devices are available no matter where
they are.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC yaml
punchy:
punch: true

#+END_SRC
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
~cipher~ is a big one. The value /must/ be identical on /all/ nodes /and/
lighthouses. ~chachapoly~ is more compatible so it's used by default. The
devices /I/ want to connect to are all x86 Linux, so I can switch to ~aes~
and benefit from [[https://www.reddit.com/r/networking/comments/iksyuu/comment/g3ra5cv/?utm_source=share&utm_medium=web2x&context=3][a small performance boost.]] Unless you know /for sure/
that you won't need to work with /anything/ else, I recommend leaving it
set to ~chachapoly~.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC yaml
cipher: chachapoly
#+END_SRC
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
The last bit I modify is the firewall section. I leave most everything
default but /remove/ the bits after ~port: 443~. I don't /need/ the ~laptop~ and
~home~ groups (groups will be explained later) to access port ~443~ on this
node, so I shouldn't include the statement. If you have different needs,
take a look at the comment explaining how the firewall portion works and
make those changes.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
Again, I /remove/ the following bit from the config.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC yaml
- port: 443
proto: tcp
groups:
- laptop
- home
2021-05-16 05:08:58 +00:00
#+END_SRC
2021-12-04 23:11:39 +00:00
**** Setting the lighthouse up
We've got the config, the certificates, and the keys. Now we're ready to
actually set it up. After SSHing into the server, grab the [[https://github.com/slackhq/nebula/releases/latest][latest
release of Nebula for your platform,]] unpack it, make the ~nebula~ binary
executable, then move it to ~/usr/local/bin~ (or some other location
fitting for your platform).
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC bash
wget https://github.com/slackhq/nebula/releases/download/vX.X.X/nebula-PLATFORM-ARCH.tar.gz
tar -xvf nebula-*
chmod +x nebula
mv nebula /usr/local/bin/
rm nebula-*
#+END_SRC
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
Now we need a place to store our config file, keys, and certificates.
#+BEGIN_SRC bash
mkdir /etc/nebula/
2021-05-16 05:08:58 +00:00
#+END_SRC
2021-12-04 23:11:39 +00:00
The next step is copying the config, keys, and certificates to the
server. I use ~rsync~ but you can use whatever you're comfortable with.
The following four files need to be uploaded to the server.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
- ~config.yml~
- ~ca.crt~
- ~buyvm.lh.nebula.example.com.crt~
- ~buyvm.lh.nebula.example.com.key~
With ~rsync~, that would look something like this. Make sure ~rsync~ is also
installed on the VPS before attempting to run the commands though;
you'll get an error otherwise.
#+BEGIN_SRC bash
rsync -avmzz ca.crt user@example.com:
rsync -avmzz config.yml user@example.com:
rsync -avmzz buyvm.lh.* user@example.com:
2021-05-16 05:08:58 +00:00
#+END_SRC
2021-12-04 23:11:39 +00:00
SSH back into the server and move everything to ~/etc/nebula/~.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC bash
mv ca.crt /etc/nebula/
mv config.yml /etc/nebula/
mv buyvm.lh* /etc/nebula/
2021-05-16 05:08:58 +00:00
#+END_SRC
2021-12-04 23:11:39 +00:00
Edit the config file and ensure the ~pki:~ section looks something like
this, modified to match your hostnames of course.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC yaml
pki:
ca: /etc/nebula/ca.crt
cert: /etc/nebula/buyvm.lh.nebula.example.com.crt
key: /etc/nebula/buyvm.lh.nebula.example.com.key
#+END_SRC
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
Run the following command to make sure everything works properly.
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC bash
nebula -config /etc/nebula/config.yml
#+END_SRC
2021-05-16 05:08:58 +00:00
2021-12-04 23:11:39 +00:00
The last step is daemonizing Nebula so it runs every time the server
boots. If you're on a machine using systemd, dropping the following
snippet into ~/etc/systemd/system/nebula.service~ should be sufficient. If
you're using something else, check the [[https://github.com/slackhq/nebula/tree/master/examples/][the examples directory]] for more
options.

2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
**** Setting individual nodes up
This process is almost exactly the same as setting lighthouses up. All
you'll need to do is generate a couple of certs and keys then tweak the
configs a bit.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
The following command creates a new cert/key for USER's node with the IP
address ~192.168.100.2~. The resulting files would go on the /remote/ node
not yours. Replace ~HOST~ and ~USER~ with fitting values.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC bash

2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
The following command will create a /similar/ cert/key but it will be part
of the ~support~ group. The files resulting from this should go on /your/
nodes. With the config we'll create next, nodes in the ~support~ group
will be able to VNC and SSH into other nodes. Your nodes need to be in
the ~support~ group so you'll have access to the others.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00

2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
On to the config now. This tells the node that it is /not/ a lighthouse,
it should /not/ resolve DNS requests, it /should/ ping the lighthouses and
tell them its IP address every 60 seconds, and the node at ~192.168.100.1~
is one of the lighthouses it should report to and query from. If you
have more than one lighthouse, add them to the list as well.

The other bit that should be modified is the ~firewall:~ section and this
is where the groups we created earlier are important. Review its
comments and make sure you understand how it works before proceeding.

We want to allow inbound connections on ports 5900, the standard port
for VNC, and 22, the standard for SSH. Additionally, we /only/ want to
allow connections from nodes in the ~support~ group. Any /other/ nodes
should be denied access.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
Note that including this section is not necessary on /your/ nodes, those
in the ~support~ group. It's only necessary on the remote nodes that
you'll be connecting to. As long as the ~outbound:~ section in the config
on /your/ node allows any outbound connection, you'll be able to access
other nodes.

The certs, key, config, binary, and systemd service should all be copied
to the same places on all of these nodes as on the lighthouse.

*** X11vnc
/Alright./ The hardest part is finished. Now on to setting ~x11vnc~ up on
the nodes you'll be supporting.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
All you should need to do is install ~x11vnc~ using the package manager
your distro ships with, generate a 20 character password with ~pwgen -s
20 1~, run the following command, paste the password, wait for ~x11vnc~ to
start up, make sure it's running correctly, press ~Ctrl~ + ~C~, then add the
command to the DE's startup applications!
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00

2021-12-04 23:11:39 +00:00
~--loop~ tells ~x11vnc~ to restart once you disconnect from the session.
~-usepw~ is pretty self-explanatory. ~-listen <nebula-ip>~ is important; it
tells ~x11vnc~ to only listen on the node's Nebula IP address. This
prevents randos in a coffee shop from seeing an open VNC port and trying
to brute-force the credentials. ~-display :0~ just defines which X11
server display to connect to.

2021-12-04 23:11:39 +00:00
Some distributions like elementaryOS and those that use KDE and GNOME
will surface a dialogue for managing startup applications if you just
press the Windows (Super) key and type ~startup~. If that doesn't work,
you'll have to root around in the settings menus, consult the
distribution's documentation, or ask someone else that might know.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
After adding it to the startup application, log out and back in to make
sure it's running in the background.

*** Remmina
Now that our network is functioning properly and the VNC server is set
up, we need something that connects to the VNC server over the fancy
mesh network. Enter [[https://remmina.org/][Remmina.]] This one goes on /your/ nodes.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
Remmina is a multi-protocol remote access tool available in pretty much
ever distribution's package archive as ~remmina~. Install it, launch it,
add a new connection profile in the top left, give the profile a
friendly name (I like to use the name of the person I'll be supporting),
assign it to a group, such as ~Family~ or ~Friends~, set the Protocol to
~Remmina VNC Plugin~, enter the node's Nebula IP address in the Server
field, then enter their username and the 20 character password you
generated earlier. I recommend setting the quality to Poor, but Nebula
is generally performant enough that any of the options are suitable. I
just don't want to have to disconnect and reconnect with a lower quality
if the other person happens to be on a slow network.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
Save and test the connection!
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
If all goes well and you see the other device's desktop, you're done
with the VNC section! Now on to SSH.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
*** SSH
First off, make sure ~openssh-server~ is installed on the remote node;
~openssh-client~ would also be good to have, but from what I can tell,
it's not strictly necessary. You /will/ need ~openssh-client~ on /your/ node,
however. If you already have an SSH key, copy it over to
~~/.ssh/authorized_keys~ on the remote node. If you don't, generate one
with ~ssh-keygen -t ed25519~. This will create an Ed25519 SSH key pair.
Ed25519 keys are shorter and faster than RSA and more secure than ECDSA
or DSA. If that means nothing to you, don't worry about it. Just note
than this key might not interact well with older SSH servers; you'll
know if you need to stick with the default RSA. Otherwise, Ed25519 is
the better option. After key generation has finished, copy
~~/.ssh/id_ed25519.pub~ (note the ~.pub~ extension) from your node to
~~/.ssh/authorized_keys~ on the remote node. The file /without/ ~.pub~ is your
/private/ key. Like the Nebula CA certificate we generated earlier, this
is extremely sensitive and should never be shared with anyone else.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
Next is configuring SSH to only listen on Nebula's interface; as with
~x11vnc~, this prevents randos in a coffee shop from seeing an open SSH
port and trying to brute-force their way in. Set the ~ListenAddress~
option in ~/etc/ssh/sshd_config~ to the remote node's Nebula IP address.
If you want to take security a step further, search for
~PasswordAuthentication~ and set it to ~no~. This means your SSH key is
/required/ for gaining access via SSH. If you mess up Nebula's firewall
rules and accidentally give other Nebula devices access to this machine,
they still won't be able to get in unless they have your SSH key. I
/personally/ recommend disabling password authentication, but it's not
absolutely necessary. After making these changes, run ~systemctl restart
sshd~ to apply them.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
Now that the SSH server is listening on Nebula's interface, it will
actually fail to start when the machine (re)boots. The SSH server starts
faster than Nebula does, so it will look for the interface before Nebula
has even had a chance to connect. We need to make sure systemd waits for
Nebula to start up and connect before it tells SSH to start; run
~systemctl edit --full sshd~ and add the following line in the ~[Unit]~
section, above ~[Service]~.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00

#+END_SRC
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
Even now, there's still a bit of a hiccup. Systemd won't start SSH until
Nebula is up and running, which is good. Unfortunately, even after
Nebula has started, it still takes a minute to bring the interface up,
causing SSH to crash. To fix /this/, add the following line directly below
~[Service]~.
2021-05-23 15:21:41 +00:00

If the ~sleep~ executable is stored in a different location, make sure you
use that path instead. You can check by running ~which sleep~.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
When the SSH /service/ starts up, it will now wait an additional 30
seconds before actually starting the SSH /daemon/. It's a bit of a hacky
solution but it works™. If you come up with something better, please
send it to me and I'll include it in the post! My contact information is
at the bottom of [[/][this site's home page.]]
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
After you've made these changes, run ~systemctl daemon-reload~ to make
sure systemd picks up on the modified service file, then run ~systemctl
restart sshd~. You should be able to connect to the remote node from your
node using the following command.
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
#+BEGIN_SRC bash
ssh USER@<nebula-ip>
#+END_SRC
2021-05-23 15:21:41 +00:00
2021-12-04 23:11:39 +00:00
If you want to make the command a little simpler so you don't have to
remember the IP every time, create ~~/.ssh/config~ on your node and add
these lines to it.
#+BEGIN_SRC text
Host USER
Hostname <nebula-ip>
User USER
#+END_SRC
Now you can just run ~ssh USER~ to get in. If you duplicate the above
block for all of the remote nodes you need to support, you'll only have
to remember the person's username to SSH into their machine.
*** Going further with Nebula
This section explains why we used FQDNs in the certs and why the DNS
resolver is enabled on the lighthouse.
Nebula ships with a built-in resolver meant specifically for mapping
Nebula node hostnames to their Nebula IP addresses. Running a public DNS
resolver is very much discouraged because it can be abused in terrible
ways. However, the Nebula resolver mitigates this risk because it /only/
answers queries for Nebula nodes. It doesn't forward requests to any
other servers nor does it attempt to resolve any domain other than what
was defined in its certificate. If you use the example I gave above,
that would be ~nebula.example.com~; the lighthouse will attempt to resolve
any subdomain of ~nebula.example.com~ but it will just ignore ~example.com~,
~nebula.duckduckgo.com~, ~live.secluded.site~, etc.
Taking advantage of this resolver requires setting it as your secondary
resolver on any device you want to be able to resolve hostnames from.
If you were to add the lighthouse's IP address as your secondary
resolver on your PC, you could enter ~host.user.nebula.example.com~ in
Remmina's server settings /instead of/ ~192.168.1.2~.
But how you do so is beyond the scope of this post!
If you're up for some /more/ shenanigans later on down the line, you could
set up a Pi-Hole instance backed by Unbound and configure Nebula as
Unbound's secondary resolver. With this setup, you'd get DNS-level ad
blocking /and/ the ability to resolve Nebula hostname. Pi-Hole would query
Unbound for ~host.user.nebula.example.com~, Unbound would receive no
answer from the root servers because the domain doesn't exist outside of
your VPN, Unbound would fall back to Nebula, Nebula would give it an
answer, Unbound would cache the answer, tell Pi-Hole, Pi-Hole would
cache the answer, tell your device, then your device would cache the
answer, and you can now resolve any Nebula host!
Exactly how you do /that/ is */definitely/* beyond the scope of this post :P
If you set any of this up, I would be interested to hear how it goes! As
stated earlier, my contact information is at the bottom of the site's
home page :)

** TODO FreeBSD quirks on the Framework laptop :FreeBSD:Framework:
:PROPERTIES:
:EXPORT_FILE_NAME: freebsd-quirks-on-the-framework-laptop
:EXPORT_HUGO_CUSTOM_FRONT_MATTER: :toc true
:END:
This is primarily intended for people new to FreeBSD. If you're already familiar
with it, [[https://wiki.freebsd.org/Laptops/Framework_Laptop][the wiki page]] will probably tell you everything you need. I had no idea
what I was doing so I had no idea what I was looking for! I had been beating my
head against a wall for about three hours before I decided to join ~#freebsd~ on
[[https://libera.chat/][Libera.Chat]]; the people there were friendly, helpful, and gave me tons of great
advice. I highly recommend popping in if you have any issues!
*** The Handbook
Open [[https://docs.freebsd.org/en/books/handbook/][the handbook.]] Follow [[https://docs.freebsd.org/en/books/handbook/][the handbook.]] Read [[https://docs.freebsd.org/en/books/handbook/][the whole handbook.]] The developers
spend a /lot/ of time making sure it's the best resource available for learning
FreeBSD. In most cases, it will have an answer for any question related to
FreeBSD.
That said, the Framework laptop is so new that it's not fully supported by the
current stable release, so for now, we'll need to diverge a bit. This guide is
really only applicable until the release of FreeBSD 13.1 and until ~drm-kmod~ hits
version 5.5+. Once those two criteria are met, following the handbook should be
entirely sufficient!
*** The Source
In section 2.5.3 of the handbook/installer, make sure you tick the ~src~ box to
download the FreeBSD source code. It'll be necessary for building our graphics
drivers later on.
*** The Graphics
This is where things are less-than-ideal at the moment. /Usually/, installing
[[https://cgit.freebsd.org/ports/tree/graphics/drm-kmod][graphics/drm-kmod]] would be sufficient, but the version in both FreeBSD's package
repos and in the ports tree is too old. At the time of writing, it's compatible
with Linux kernel 5.4 while the Framework's drivers are in Linux kernel 5.5+.
We'll need to clone the /sources/ for ~graphics/drm-kmod~, check out a more recent
branch, build the drivers, and use those instead.
I'm not 100% certain whether the first step here is necessary but I don't feel
like reinstalling to check.
1. Install ~graphics/drm-kmod~ with ~pkg install drm-kmod~
2. Install ~devel/git~ with ~pkg install git~
3. Clone ~drm-kmod~'s source with
#+BEGIN_SRC bash
git clone https://github.com/freebsd/drm-kmod
#+END_SRC
4. Check out the ~5.7-stable~ branch with
#+BEGIN_SRC bash
git checkout -b 5.7-stable --track remotes/origin/5.7-stable
#+END_SRC
5. Build the package with ~make~
6. Uninstall ~drm-kmod~ and all of its dependencies with ~pkg remove drm-kmod~
followed by ~pkg autoremove~
7. Install the more up-to-date drivers with ~make install~
8. Make sure the module works as expected with ~kldload /boot/modules/i915kms.ko~
9. If you suddenly see grey in your terminal, it works! Go ahead and add it to
your boot config by appending the following line to ~/etc/rc.conf~
#+BEGIN_SRC text
kld_load="/boot/modules/i915kms.ko"
#+END_SRC
10. Reboot and you should be able to start Xorg as the handbook describes!
Again all of this information is available on [[https://wiki.freebsd.org/Laptops/Framework_Laptop][the FreeBSD wiki page for the
Framework laptop.]] The ~Graphics~ row in section 2 says /requires DRM-KMOD 5.5 or
higher. Fails to initialize with DRM-KMOD 5.4./ That's in reference to the
package we just built and installed.
Hope this helps!

I've never been satisfied with any of the email clients most people use.
I've tried [[https://www.thunderbird.net/en-GB/][Thunderbird,]] [[https://wiki.gnome.org/Apps/Evolution][Evolution,]] [[https://getmailspring.com/][Mailspring,]] [[https://support.apple.com/mail][Mail.app,]] [[https://roundcube.net/][Roundcube,]]
[[https://sogo.nu/][SOGo,]] [[https://wiki.gnome.org/Apps/Geary][Geary,]] and /many/ more. /None/ of them handle multiple accounts
particularly well because all of the emails associated with that account
are bound within it. Sure, you can make a new folder somewhere called
~TODO~ and move all of your actionable emails to that folder but, when you
go to move actionable emails from /another/ account into that folder,
you'll likely find that the client simply doesn't let you. If it does,
when you reply, it will likely be sent from the wrong account. This is a
limitation of the IMAP protocol; everything is /managed/ locally but
changes are pushed to the remote server and mixing things the way I want
leads to broken setups.
Before I go any further, these are a few characteristics of my ideal
email tool.
- Support for multiple accounts (obviously)
- /Native desktop application/ (*not* [[https://github.com/electron/electron][Electron]])
- Has stellar keyboard shortcuts
- Doesn't require internet connectivity (other than downloading and
sending of course)
- Organisation can be done with tags
*** Why tags?
Because they're better. Hierarchies are useful for prose and code but
not for files, emails, notes, or anything where an item may fit within
multiple categories. Imagine you get an email from your Computer Science
professor that includes test dates, homework, and information about
another assignment. In that same email, he asks every student to reply
with something they learned from the previous class as a form of
attendance. In a hierarchy, the best place for this might just be a ~TODO~
folder /even though/ it would also fit under ~School~, ~CS~, ~Dates~, ~To read~,
and ~Homework~. Maybe you have a few minutes and want to clear out some
emails that don't require any interaction. In a tag-based workflow, this
would be a good time to open ~To read~, get that email out of the way, and
remove the ~To read~ tag. It would still show up under the other tags so
you can find it later and take the time to fully answer the professor's
question, add those dates to your calendar, and add the homework
assignments to your ~TODO~ list. Hierarchies can be quite cumbersome to
work with, especially when one folder ends up getting all the data. Tags
ensure that you only see what you want when you want it. Tags are more
efficient and they will remain my organisation system of choice.
*** The tools
In short, the tools we will be using are...
2021-09-02 14:36:03 +00:00
+ [[https://isync.sourceforge.io/mbsync.html][~mbsync~]] to download our emails
+ [[https://notmuchmail.org/][~notmuch~,]] the primary way emails will be organised
+ [[https://afew.readthedocs.io/en/latest/][~afew~]] to apply initial ~notmuch~ tags based on subject, sender, recipient, etc.
+ [[https://neomutt.org/][NeoMutt]] to interact with those emails, reply, compose, add/remove
tags, etc.
+ [[https://marlam.de/msmtp/][~msmtp~]] for relaying our replies and compositions to our mail provider
Yes, it's a lot. Yes, it's time-consuming to set up. Yes, it's worth it
(in my opinion).
2021-09-02 14:36:03 +00:00
*** ~mbsync~
As I said above, IMAP is limiting; we need to use some other method of
downloading our emails. There's an awesome piece of software called
2021-09-02 14:36:03 +00:00
[[https://isync.sourceforge.io/mbsync.html][mbsync]] which is built for exactly this purpose. Its configuration
can be rather daunting if you have as many accounts as I do (19) but
it's not /terrible/.
2021-09-02 14:36:03 +00:00
The following sections are named *Near*, *Far*, and *Sync*. Near and Far are
terms mbsync uses to profile /how/ your emails are stored, /where/ they're
stored, and how to interact with them. In this guide, Far will our mail
provider's IMAP server and Near will be our local Maildir.

#+END_SRC
The repository sections describe how the emails are stored or retrieved.
In the ~local~ block, you'll notice that the type is ~Maildir~. In this
format, each email is given a unique filename and stored in a hierarchy
of folders within your account. This is often how your emails are stored
on your provider's mail server.
~pythonfile~ is used here to authenticate with the remote server. This can
be complicated and depends /entirely/ on how you manage your passwords. I
use [[https://keepassxc.org/][KeePassXC]] and love it. When I set OfflineIMAP up, however, it didn't
have ~libsecret~ compatibility. This would have made setup significantly
easier but, as it already just works™, I don't really see a reason to
change it.
This new feature allows ~libresecret~-based applications to query
KeePassXC for your passwords or store them there on your behalf. CLI/TUI
applications that need a secure mechanism for background authentication
can use ~secret-tool lookup Title "TITLE_OF_PASSWORD"~ as the password
command. See [[https://github.com/keepassxreboot/keepassxc/pull/2726][the pull request]] for more details. Because this wasn't a
feature when I first set it up, I put my passwords in plaintext files
and encrypted them with the GPG key stored on my YubiKey. As long as my
key is plugged in, OfflineIMAP can authenticate and download all my
emails just fine. The process for using a GPG key /not/ stored on a
hardware token is pretty much the same and I'll talk about that process
instead.
These are the contents of my ~~/.offlineimap.py~.
#+BEGIN_SRC python
#! /usr/bin/env python2
from subprocess import check_output
def get_pass(account):
return check_output(["gpg", "-dq", f" ~/.mail_pass/{account}.gpg"]).strip("\n")
#+END_SRC
This runs ~gpg -dq ~/.mail_pass/use_exa.gpg~ then strips the newline
character before returning it to OfflineIMAP. ~-d~ tells GPG that you're
passing it a file you want decrypted and ~-q~ tells it not to give any
output other than the file's contents. For a setup that works with this
Python script, put your passwords in plaintext files with the account
name as the file name (e.g. ~use_exa~). You'll then encrypt it with ~gpg
-er <YOUR_KEY_ID> use_exa~. Running ~gpg -dq use_exa.gpg~ should display
your password. Repeat for every account and store the resulting files in
~~/.mail_pass/~.
The other option, ~sync_deletes~, is whether or not to delete remote
emails that have been deleted locally. I enabled that because I want to
have easy control over how much remote storage is used.
Here's the next block again so you don't have to scroll up:
#+BEGIN_SRC text
[Repository use_exa-remote]
type = IMAP
remotehost = imap.example.com
starttls = yes
ssl = no
remoteport = 143
remoteuser = user@example.com
remotepasseval = get_pass("use_exa")
auth_mechanisms = GSSAPI, XOAUTH2, CRAM-MD5, PLAIN, LOGIN
maxconnections = 1
createfolders = True
sync_deletes = yes
#+END_SRC
This one's pretty self-explanatory. ~type~, ~remotehost~, ~starttls~, ~ssl~, and
~remoteport~ should all be somewhere in your provider's documentation.
~remoteuser~ is your email address and ~remotepasseval~ is the function that
will return your password and allow OfflineIMAP to authenticate. You'll
want enter the name of your password file without the ~.gpg~ extension;
the script takes care of adding that. Leave ~auth_mechanisms~ alone and
the same for ~maxconnections~ unless you know your provider won't rate
limit you or something for opening multiple connections. ~sync_deletes~ is
the same as in the previous block.
Copy those three blocks for as many accounts as you want emails
downloaded from. I have 510 lines just for ~Account~ and ~Repository~ blocks
due to the number of address I'm keeping track of.
*** ~notmuch~
[[https://notmuchmail.org/][~notmuch~]] is /a fast, global-search, and tag-based email system/. This
what does all of our organisation as well as what provides the "virtual"
mailboxes NeoMutt will display later on. Configuration is incredibly
simple. This file goes in ~~/.notmuch-config~.
#+BEGIN_SRC text
[database]
path=/home/user/mail/
[user]
name=Amolith
primary_email=user@example.com
[new]
tags=unread;new;
ignore=Trash;
[search]
exclude_tags=deleted;spam;
[maildir]
synchronize_flags=true
#+END_SRC
First section is the path to where all of your archives are, the ~[user]~
section is where you list all of your accounts, ~[new]~ adds ~tags~ to mail
notmuch hasn't indexed yet and ignores indexing the ~Trash~ folder, and
~[search]~ ignores mail tagged with ~deleted~ or ~spam~. The final section
tells ~notmuch~ to add maildir flags which correspond with ~notmuch~ tags.
These flags will be synced to the remote server the next time
OfflineIMAP runs and things will be somewhat organised in your webmail
interface.
After creating the configuration file, run ~notmuch new~ and wait for all
of your mail to be indexed. This could take a short amount of time or it
could take minutes up to an hour, depending on how many emails you have.
After it's finished, you'll be able to run queries and see matching
emails:
#+BEGIN_SRC text
$ notmuch search from:user@example.com
thread:0000000000002e9d December 28 [1/1] Example User; Random subject that means nothing
#+END_SRC
This is not terribly useful in and of itself because you can't read it
or reply to it or anything. That's where the Mail User Agent (MUA) comes
in.
*** ~afew~
[[https://afew.readthedocs.io/en/latest/][~afew~]] is /an initial tagging script for notmuch/. After calling ~notmuch
new~, ~afew~ will add tags based on headers such as ~From:~, ~To:~, ~Subject:~,
etc. as well as handle killed threads and spam. The official [[https://afew.readthedocs.io/en/latest/quickstart.html][quickstart
guide]] is probably the best resource on getting started but I'll include
a few tips here as well.
*** NeoMutt
*** ~msmtp~
~msmtp~ is what's known as a /Mail Transfer Agent/ (MTA). You throw it an
email and it will relay that to your mail provider's SMTP server so it
can have the proper headers attached for authentication, it can be sent
from the proper domain, etc. All the necessary security measures can be
applied that prevent your email from going directly to spam or from
being rejected outright.
~msmtp~'s configuration is also fairly simple if a bit long, just like
OfflineIMAP's.
#+BEGIN_SRC text
# Set default values for all following accounts.
defaults
# Use the mail submission port 587 instead of the SMTP port 25.
port 587
# Always use TLS.
tls on
#+END_SRC
This section just sets the defaults. It uses port 587 (STARTTLS) for all
SMTP servers unless otherwise specified and enables TLS.
#+BEGIN_SRC text
account user@example.com
host smtp.example.com
from user@example.com
auth on
user user@example.com
passwordeval secret-tool lookup Title "user@example.com"
#+END_SRC
This section is where things get tedious. When passing an email to
~msmtp~, it looks at the ~From:~ header and searches for a block with a
matching ~from~ line. If it finds one, it will use those configuration
options to relay the email. ~host~ is simply the SMTP server of your mail
provider, sometimes this is ~mail.example.com~, ~smtp.example.com~, etc.
I've already explained ~from~, ~auth~ simply says that a username and
password will have to be provided, ~user~ is that username, and
~passwordeval~ is a method to obtain the password.
When I got to configuring ~msmtp~, [[https://keepassxc.org/][KeePassXC]] had just released their
~libsecret~ integration and I wanted to try it. ~secret-tool~ is a command
line tool used to store and retrieve passwords from whatever keyring
you're using. I think KDE has ~kwallet~ and GNOME has ~gnome-keyring~ if
you already have those set up and want to use them; the process should
be quite similar regardless.
As mentioned above ~secret-tool~ stores and retrieves passwords. For
retrieval, it expects the command to look like this.
#+BEGIN_SRC text
secret-tool lookup {attribute} {value} ...
#+END_SRC
I don't know what ~kwallet~ and ~gnome-keyring~'s attributes are but
this can be used with KeePassXC by specifying the ~Title~ attribute. If
the password to your email account is stored in KeePassXC with the
address as the entry title, you can retrieve it by simply running...
#+BEGIN_SRC text
secret-tool lookup Title "user@example.com"
#+END_SRC
If you have a different naming system, you'll have to experiment and try
different things; I don't know what KeePassXC's other attributes are so
I can't give other examples.
#+BEGIN_SRC text
passwordeval gpg -dq ~/.mail_pass/use_exa.gpg
#+END_SRC
Now that the whole block is assembled, copy/paste/edit for as many
accounts as you want to send email from.

Five days ago at the time of writing, [[https://github.com/crsib][Dmitry Vedenko]] opened a Pull
Request (PR) in [[https://github.com/audacity/audacity/pull/835][Audacity's GitHub repository]] entitled [[https://github.com/audacity/audacity/pull/835][/Basic telemetry
for the Audacity/.]] About two days later, all hell broke loose. That PR
now has over 3.3 thousand downvotes and more than one thousand comments
from nearly 400 individuals. I started reading the posts shortly after
they began and kept up with them over the following days, reading every
single new post. I recognise that few people are going to feel like

I haven't been able to find /much/ information in this area so forgive me
if I'm scant on details.

2021-12-04 23:11:39 +00:00
On 30 April, a company called [[https://mu.se/][Muse Group]] acquired [[https://www.audacityteam.org/][Audacity.]] According to
[[https://mu.se][their website]], Muse is the parent company behind many musical
applications and tools. It was founded by Eugeny Naidenov just days
before it acquired Audacity. Before all of this, Eugeny Naidenov founded
[[https://www.ultimate-guitar.com/][Ultimate Guitar]] (UG) in 1998. The service grew rather quickly and now
has over 300 million users. UG acquired [[https://deanzelinsky.com/][Dean Zelinsky Guitars]] in 2012,
[[http://agilepartners.com/][Agile Partners]] in 2013, [[https://musescore.org/][MuseScore]] in 2017, and [[http://trycrescendo.com/][Crescendo]] in 2018. Muse
Group was established in 2021 and it seems as if all of the services UG
acquired were (or will be) transferred to Muse Group, as well as UG
itself. Immediately following its establishment, Muse not only acquired
Audacity but also [[https://www.staffpad.net/][StaffPad.]]
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
I say 30 April because that's when Muse published their [[https://mu.se/newsroom/tpost/6dhedma301-muse-group-acquires-audacity-expanding-c][press release]]
and when Martin Keary (Tantacrul) published a video entitled [[https://www.youtube.com/watch?v=RMWNvwLiXIQ][/Im now in
charge of Audacity. Seriously./]] According to his comment,[fn:17] Martin
will help with proposing Audacity's roadmap and many of its future
features as well as working with the community. This has been his role
with MuseScore since he joined that project and he will be continuing it
here.

*** Telemetry implementation
**** Implementation Basics
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
A few days after the acquisition, a PR was opened that adds /Basic
telemetry for the Audacity/. This implementation collects "application
opened" events and sends those to Yandex to estimate the number of
Audacity users. It also collects session start and end events, errors
for debugging, file used for import and export, OS and Audacity
versions, and the use of effects, generators, and analysis tools so they
can prioritise future improvements. Sending this data would be optional
and the user would be presented with a dialogue the first time they
launch the application after installation or after they update to the
including release. This description was mostly copied directly from [[https://github.com/audacity/audacity/pull/835#issue-629891447][the
PR description itself.]]
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
**** Frontend Implementation
This is fairly straightforward and a pretty standard UI for prompting
users to consent to analytics and crash logging. This section is
included because the community has strong opinions regarding the
language used and its design, but that will be discussed later. The
screenshot below is copied directly from the PR.

key, they unintentionally consent to data collection. If the user
desires, this can later be changed in the settings menu. However, if
they weren't aware what they were consenting to /or that they did
consent/, they won't know to go back and opt out.

*** Community opinions
There were many strong opinions regarding both the frontend and backend
implementations of this PR, from the wording of the dialogue and
highlighting the consent button to devices running something other than
Windows and macOS not being able to send telemetry and thus skewing the
data that /was/ collected.
2021-11-01 06:55:26 +00:00

**** Opinions on the frontend
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
Really, the only frontend here is the consent dialogue. However, there
are /many/ comments about it, the most common of which is probably that
the wording is not only too vague[fn:13] but also inaccurate.[fn:14] The
assertion that Google Analytics are not anonymous and any data sent can
be trivially de-anonymised (or de-pseudonymised) is repeated many times
over. Below are a few links to comments stating such. I searched for the
term /"anonymous"/, copied relevant links, and stopped when my scrollbar
reached halfway down the page.

2021-12-04 23:11:39 +00:00
The next most pervasive comment is regarding the consent buttons at the
bottom of the dialogue where users opt in or out.[fn:15] Many individuals call
this design a /dark pattern/. Harry Brignull, a UX specialist focusing on
deceptive interface practises, describes dark patterns as [[https://www.darkpatterns.org/][/tricks used
in websites and apps that make you do things that you didn't mean to/.]]
The dark pattern in this situation is the opt-in button being
highlighted. Many community members assert that users will see the big
blue button and click it without actually reading the dialogue's
contents. They just want to record their audio and this window is a
distraction that prevents them from doing so; it needs to get out of the
way and the quickest way to dismiss it is clicking that blue button.
Below is a list of some comments criticising this design.

Another issue that was brought up by a couple of individuals was the
lack of a privacy policy.[fn:16] The consent dialogue links to one, but, at the
time of writing, one does not exist at [[https://www.audacityteam.org/contact/privacy-policy/][the provided URL.]] I have [[https://web.archive.org/web/20210510012924/https://www.audacityteam.org/contact/privacy-policy/][archived

The issue many individuals take with this snippet is saving the
~ClientID~. Say an individual has an odd file that causes Audacity to
crash any time they try to open it. Say they attempt to open it a
hundred times. Without giving the client a unique ID, it could look like
there are 100 people having an issue opening a file instead of just the
one. However, by virtue of each installation having an entirely unique
ID, this telemetry /is not anonymous/. Anonymity would be sending
statistics in such a way that connecting those failed attempts to a
single user would be impossible. At best, this implementation is
/pseudonymous/ because the client is given a random ID, you don't have to
sign in with an account or something.

Timothe Litt's comment gives a good description of why "vendoring in"
libcurl is a bad idea[fn:19] and Tyler True's comment gives a good
overview of the pros and cons of doing so.[fn:18] Many people take issue
with this /specifically/ because it's libcurl. Security flaws in it are
/very/ common and Audacity's copy would need to be /manually/ kept up to
date with every upstream release to ensure none of its vulnerabilities
can be leveraged to compromise users. If the Audacity team was going to
stay on top of all of the security fixes, they would need to release a
new version every week or so.

The problem with downloading curl at build-time is that it's simply
disallowed for many Linux- and BSD-based operation systems. When a
distribution builds an application from source, its build dependencies
are often downloaded ahead of time and, as a security measure, the build
machine is cut off from the internet to prevent any interference.
Because this is disallowed, the build will fail and the application
won't be available on those operation systems.

2021-12-04 23:11:39 +00:00
Note, however, that these build machines would have the option to
disable telemetry at build-time. This means the machine wouldn't attempt
to download curl from GitHub and the build would succeed but, again,
telemetry would be disabled for anyone not on Windows or macOS. This
defeats the whole purpose of adding telemetry in the first place.

I like writing things down. I like the feel of the pen (preferably a
fountain pen) gliding smoothly over the paper, that nice solid feeling
of the tip against the table, seeing the ink dry as it flows from the
nib, accidentally swiping my hand through it before it's finished and
smearing a bit of ink across the page, then cursing under my breath as I
dab it up with a handkerchief or a napkin or something else nearby. I
also love that writing things by hand [[https://journals.sagepub.com/doi/abs/10.1177/0956797614524581][has an impact on memory and
improves retention.]]
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
*** The problem
Unfortunately, I don't love keeping up with that paper. Across many
different classes, even with dedicated folders for each one, something
important inevitably gets lost. Notebooks are also bulky and can take up
a lot of space. I tried [[https://bulletjournal.com/][bullet journalling]] for about a month earlier
this year and, while the process was enjoyable, the maintenance was not.
My brain moves faster than my pen (even though I have terrible
handwriting) and I inevitably forget letters or even whole words. This
is a problem while writing in pen because white-out looks ugly and I
dislike wasting whole pages because of a couple mistakes.
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
The obvious solution here is to get an iPad with an Apple Pen, right?
Right??
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
Wrong because Apple bad.[fn:2]
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
*** The solution
Enter the world of ... what are they even called? E-ink notebooks? Paper
tablets? E-R/W?[fn:1] Do they even have a "device category" yet? I don't
know, but they solve my problem in a wonderful way.
2021-09-29 00:18:10 +00:00
2021-12-04 23:11:39 +00:00
As the names suggest, these are devices that can /usually/ open and read
e-books (EPUBs, PDFs, etc.), annotate them, and create standalone pages
of notes as if they were full notebooks. The most well-known of these
devices is likely the [[https://remarkable.com/][reMarkable.]] They had a [[https://venturebeat.com/2019/10/08/remarkable-raises-15-million-to-bring-its-e-paper-tablets-to-more-scribblers/][hugely successful
crowdfunding campaign]] and produced the reMarkable 1, followed by [[https://blog.remarkable.com/remarkable-2-the-next-generation-paper-tablet-91b47d0080cb][the
reMarkable 2 in 2020.]] There are a few devices like these by now but
we'll look at the reMarkable first.
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
*** The reMarkable
This device boasts all of the features I was looking for. It renders
digital content, from books and manuals to comics and manga, allows you
to mark those documents up as you would if they were physical media,
create full notebooks of hand written text, organise them, search, and,
if your handwriting is legible enough (mine certainly is not), perform
OCR on your notes and email a transcription to yourself. It even runs
Linux and the developers have opened SSH up so you can remote in and
tinker with it as much as you like. Because of this, there's a pretty
awesome [[https://github.com/reHackable/awesome-reMarkable][community of people creating third-party tools and integrations]]
that add even further functionality. My favourite is probably [[https://github.com/bordaigorl/rmview][rMview,]] a
really fast VNC client for the reMarkable that allows you to view your
device's screen on any computer.
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
After watching all of [[https://www.youtube.com/c/MyDeepGuide][MyDeepGuide's]] [[https://www.youtube.com/playlist?list=PLsSI9-gaSSmiXwb7Vjk5Vb-nB41UTnrXd][extensive playlist on the
reMarkable,]] however, I decided to go with a different product.
*** Enter the Supernote A5X
The [[https://www.supernote.com/#/product?type=SN-A5-X][Supernote A5X]] has all of the basic features the reMarkable has:
reading documents, writing notes, and organising your content. Its
implementation, on the other hand, seems to be much more polished. It
also lacks some features from the reMarkable while adding others.
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
*** Operating System
While the reMarkable runs Codex,[fn:3] a /"custom Linux-based OS
optimised for low-latency e-paper"/, the Supernote just runs Android.
There are both benefits and detriments to this; on one hand, they're
running all of Android, bloated that it is, on a very lightweight
tablet. On the other, they don't have to develop and maintain a custom
operating system. This allows them to focus on other aspects that are
arguably more important so I don't actually mind that it runs Android.
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
The only place that Android stands out is in system operations; file
transfer uses MTP and, when you swipe down from the top of the device, a
small bar appears similar to what was in early Android. This lets you
change WiFi networks, sync with the Supernote Cloud, take a screenshot,
search, and access the system settings. Nothing else about the device
really screams Android to me.

*** Community
I don't usually browse Reddit but [[https://old.reddit.com/r/Supernote/][the Supernote community]] there is
fascinating. I haven't looked around enough to know exactly what his
relationship is with the company, but one of the members, [[https://old.reddit.com/user/hex2asc][u/hex2asc,]]
seems to represent Supernote in something of an official capacity. He's
incredibly active and usually responds to posts and questions within a
day or two.
2021-09-29 00:18:10 +00:00
2021-12-04 23:11:39 +00:00
Before I purchased a Supernote, [[https://old.reddit.com/r/Supernote/comments/lhffyd/sync_targets_open_document_formats_and_crossnote/][I wrote a post]] asking about a couple of
things that concerned me: sync targets, open document formats, and
cross-note links. I don't really plan to write full documents on the
device but having the option to do so would still be nice. The other
features are absolutely killer for me as I would like to maintain a
Zettelkasten (I wrote about [[/vim-as-a-markdown-editor/][using Vim to do so]] last year but didn't end
up sticking with it) and manage document synchronisation with my own
Nextcloud server. The community was quick to respond and confirm that
Zettelkasten functionality would be implemented soon™. u/hex2asc
responded /the day after/ and said that WebDAV would be supported but not
earlier than May (September update: it's still not supported), ODF would
likely not be supported, and cross-note links were definitely a
possibility. Another community member has been avidly following the
subreddit and even put together an [[https://app-rm.roadmunk.com/publish/03e6dca3d769e2b7015f7f48a649cb3f75f44d9e][unofficial roadmap.]]

2021-12-04 23:11:39 +00:00
The following images are screenshots of the full page above with the
possible UI variations while reading a book. This first one is default,
with the editing bar at the top. It is exactly the same as what's
displayed on the blank pages for hand writing full notes. From left to
right is the Table of Contents toggle, the pen tools (fineliner,
"fountain" pen,[fn:5] and highlighter), the erasers, lasso select tool,
undo/redo, context menu, palm rejection toggle, previous page, goto
page, next page, and exit.

2021-12-04 23:11:39 +00:00
You can hold your finger on that bar and drag it down to detach it from
the top. The default width exposes all the tools without whitespace. You
can move it around the screen by dragging the circle with a straight
line through the middle on the far left.

2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
If you tap that circle, the width shrinks and everything except the
pens, erasers, and undo/redo buttons are hidden. It can be dragged the
same was as in the previous image and tapping that circle will expand
the bar again.

The last mode is with the bar completely hidden. You achieve this just
by dragging it to the right edge of the screen. Once hidden, you can
swipe right to left from the edge and it will be revealed flush with the
right edge.

*** Experience
**** Reading content
I love e-ink. I think it looks beautiful and would love to have an e-ink
monitor.[fn:4] That said, the Supernote has an especially nice display
with 226 PPI (pixels per inch). The image below was taken with my
phone's camera so it's not very good. However, if you zoom in a bit, you
can see that the curved edges of some letters are /slightly/ pixellated.
Viewing with my naked eye at a comfortable distance, it does look better
/to me/ than some of my print books, however.
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
[[~/repos/sites/secluded/static/assets/pngs/supernote-resolution.png]]
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
/At the moment,/ I am pretty disappointed with Table of Contents detection
for ePUBs. A great many of my books seem to use a legacy ToC format that
the Supernote sees and tries/fails to read before attempting to read the
more up-to-date one. This is easily remedied by editing the ePUB in
[[https://calibre-ebook.com/][Calibre,]] going to Tools → Upgrade Book Internals → Remove the legacy
Table of Contents in NCX format. You might need to make a small change
to one of the HTML files and revert it before the save button is
enabled. After that, just copy it back over to the Supernote and
everything should work properly.
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
**** Writing notes
I write notes as often if not /more/ often than I read and annotate books.
It's the main reason I purchased the device and I love the experience.
The Supernote doesn't /really/ feel like paper despite what their
marketing materials claim, though it doesn't feel /bad/ either. It's hard
to describe but I would say it's something like writing with a
rollerball pen on high-quality paper with a marble counter underneath:
incredibly smooth with but a little bit of texture so it doesn't feel
like writing on a glass display.
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
While writing latency[fn:6] is noticeable, I really don't have a huge
issue with it. I write very quickly but find that the slight latency
actually makes writing /more/ enjoyable. It sounds weird and I'm not sure
why, but I /really/ like writing on the Supernote; it's wonderfully
smooth, pressure-sensitive, the latency makes things interesting, and
[[https://supernote.com/#/part?id=SP-04][the Heart of Metal pen]] feels good in my hand.
2021-11-01 06:55:26 +00:00
2021-12-04 23:11:39 +00:00
**** Surfacing Content
While organisation is done using a regular filesystem hierarchy, the
Supernote does have other ways to search for and surface your notes. As
you're writing, you can use the lasso select tool and encircle a word. A
little dialogue pops up and gives you a few buttons for things you can
do with that selection: copy, move to another page, cut, add it to the
Table of Contents, or mark it as a key word. If you select the key word
icon, the Supernote does some incredible OCR[fn:7] on it and displays a
dialogue where you can add it to the note file as a tag. This dialogue
allows you to edit the word before adding it just in case the OCR was
wonky. Even with my terrible handwriting, I've found that it works very
well and I rarely have to make edits.
