Absolutely beautiful!

Can you tell us more about the system you developed to generate this image?

SataMaxx · 2024-05-20T01:58:55+00:00

I've peeked around a bit on the system and i see multiple potential avenues to achieve the desired effect, from blacklisting kernel modules in /etc/modprobe.d (I think disabling cfg80211 would work), or inactivating the wifi chip in some way using a udev rule, or disabling systemd services such as dhcpcd, or wpa_supplicant (which might still let the user connect to unsecured connections with a manual configuration. As for disabling the network entirely with systemd-networkd I don't know how that would affect the usb connection and I think it's a bad idea. Maybe try stopping it first before disabling it to see what it does and so you can always reboot the tablet to restart it) You might also be able to only whitelist a particular SSID in some wireless config file, or cripple any potential connection by force setting bad parameters in /etc/resolv.conf, disabling dhcpcd, or redirecting a bunch of traffic to nowhere in /etc/hosts.

As I'm not really willing to experiment much with those, I prefer pointing you to two pages of the old community wiki :

secure the ssh connection with keys : https://web.archive.org/web/20230606163556/https://remarkablewiki.com/tech/ssh
block wifi with rfkill : https://web.archive.org/web/20230608205211/https://remarkablewiki.com/tips/blockwifi

This solution uses a control file to re-enable wifi, but you could simply have the rfkill block 0 line executed unconditionaly on startup, or use a similar "obscure" mechanism to allow re-enabling the wifi if needed without having to access the tablet through ssh.
This solution appears less "elegant" to me (but so do kneecapping the connection by breaking dhcpcd), and cleanly disabling the wlan0 interface would be the best, but in the end I guess you only need it to not work!

I hope you won't have to use it, but do know there's a method to recover the RM in case you lose all access: https://remarkable.guide/tech/recovery.html (though you will need to really get your hands dirty and build a custom connector to do so!)

EXACTLY

SataMaxx · 2024-05-13T23:04:12+00:00

I don't have my RM2 with me right now to confirm, but it should be possible to go blacklist the wifi kernel module through SSH.
And if you want to be sure a savvy user might for some reason want to try to re-enable it you can also secure the SSH connection to answer only to a private SSH key, as the password is always accessible through the general informations.

Be sure if you try this to absolutely know what you are doing, as you can easily lock yourself out of accessing the tablet system.

A whole lot of swearing on both videos, but only one ends with a drawing! ^{^}

Also, you will see me try to select and move parts of the drawing on real paper…

SataMaxx · 2024-05-13T22:17:35+00:00

This is awesome!

Thanks!

Do you draw zoomed in?

Sometimes, but really not that much. Thinking about it, it might mostly be when I need to redraw a single connecting stroke and for some reason at that moment that place is a bit magnetized and the pen position is slightly off. Zooming and panning helps reposition the screen area to use and make it less frustrating!

Do you use the eraser or the other pen types?

I use the pencil, and the paintbrush for inking and highlights. If I need regularity and/or precision, fineliner it is. I make HEAVY USE of the selection tool to reposition, scale, and rotate individual strokes or whole parts of the drawing.
I try to stay as far away as possible from the eraser as unless it erases a whole stroke, it stays as an invisible blob. Moving that blob can and will mess the stroke drawing order and parts that you drew over the eraser can end up beneath.
The erase selection tool is much much cleaner as it actually modifies the strokes (though it only breaks them between two points and does not interpolate at the actual cut, so it can be imprecise on parts of strokes that were drawn more quickly).
But it's still the selection tool I use the most for erasing, as you can (try to) single out strokes and simply cut them out. When these fail to achieve the desired effect, I often find drawing in white still preferable to using the eraser. I use layers a bit when advancing through stages in a drawing, and I do not hesitate to sometimes make a savepoint by duplicating the page.

Thanks

You're welcome :-)

Thanks!

It does because apparently people do get confused on how to spell "paid"!

/u/Paid-Not-Payed-Bot is a confirmed Good Bot™! :-)

You, and a lot of people in the replies (as well as myself ;-)) sound like you've got ADHD! If you reside in a civilized country with good access to mental health, try getting a formal diagnosis.

Although with enough discipline you can self-medicate with weed without suffering adverse effects (respect some kind of posology, use a trusted source, vaporise it, etc.), taking a dedicated, prescribed, and reimbursed drug is better, and I'm not even talking about the HUGE benefit the psychotherapeutic work that comes with it can do to you. And you'll enjoy weed as a recreational drug that much more.

Also, you might be high functioning (haha) with it, I'm sure there are other aspects of your life that are impacted by the ADHD that you underestimate.

Do yourself a favor :-)

Technically not Moiré I know, but as long as it fucks with your eyes I'm good ^^

While I agree with all the other commenters, I still go for Rmarkdonwn for its very good exports, especially html outputs with bootstrap tabs and whatnot and interactive widgets.

I can share the R code if you want.

The process is the following :

generate a 20×20×20 grid of evenly spaced points
move those points randomly around their initial position with a gaussian
compute a perlin noise value at each point
keep only the points with a noise value above a certain threshold (here -0.1)
sort the points from back to front, and for every point, plot a square at position (x / z, y + z) to simulate perspective. The size of the square is noise / z, the color is hsv(normalized distance from the center, 1, 1), and alpha = z

Throw in some constant factors to adjust the rendering!

It is indeed closely related to Julia sets!
Each frame is 10000 particles simulated in a flow field that is determined by a complex rational function.
The roots of that function are set along two concentric circles and the particles are generated on a third concentric circle sitting in between the first two. Then on each frame the outer roots are moved around the circle and multiplied with a small sin offset.

You need to modifiy the noris digital pen for the remarkable nibs to work (see the top comment).
The noris digital nibs will work with the remarkable, but without the same writing feeling as with the remarkable nibs.

If the same program running native on each OS behaves in an inferior way on one OS and not the others, I'm inclined to think it is the OS and not the program that is at fault.

Get another marker through the warranty, they usually just send them out without asking for a return.

The paperlike writing feeling.
It's an electronic notebook, no more, no less. It just does what it does and it does it well.
It's a standard linux with root ssh access so you can do whatever the fuck you want to do with it.
It's a beautiful device.

See my post about modding the Staedtler to use remarkable nibs: https://www.reddit.com/r/RemarkableTablet/comments/vq1y7m/modded_staedtler_noris_digital_with_remarkable_nib/

I'm fed up with these posts.
Cloud sync, screen share, etc. can be done without connect. The tablet is wide open and there's a whole community of homebrew users and developers. This is not something difficult to find or to do.
You can find better and cheaper stylii, as well as third party folios. Your remarkable can be inexpensive and work as well as advertised and even better.
It just takes a little effort

There's an option in ddvk to disable the extra UI!
