I write code and play games and stuff. My old username from reddit and HN was already taken and I couldn’t think of anything else I wanted to be called so I just picked some random characters like this:
>>> import random
>>> ''.join([random.choice("abcdefghijklmnopqrstuvwxyz0123456789") for x in range(5)])

My avatar is a quick doodle made in KolourPaint. I might replace it later. Maybe.

Can Z3 account for lost bits? Did it come up with just one solution?
It gave me just one solution the way I asked for it. With additional constraints added to exclude the original solution, it also gives me a second solution – but the solution it produces is peculiar to my implementation and does not match your implementation. If you implemented exactly how the bits are supposed to end up in the result, you could probably find any other solutions that exist correctly, but I just did it in a quick and dirty way.
This is (with a little clean up) what my code looked like:
#!/usr/bin/env python3
import z3
rand1 = 0.38203435111790895
rand2 = 0.5012949781958014
rand3 = 0.5278898433316499
rand4 = 0.5114834443666041
def xoshiro128ss(a,b,c,d):
t = 0xFFFFFFFF & (b << 9)
r = 0xFFFFFFFF & (b * 5)
r = 0xFFFFFFFF & ((r << 7 | r >> 25) * 9)
c = 0xFFFFFFFF & (c ^ a)
d = 0xFFFFFFFF & (d ^ b)
b = 0xFFFFFFFF & (b ^ c)
a = 0xFFFFFFFF & (a ^ d)
c = 0xFFFFFFFF & (c ^ t)
d = 0xFFFFFFFF & (d << 11 | d >> 21)
return r, (a, b, c, d)
a,b,c,d = z3.BitVecs("a b c d", 64)
nodiv_rand1, state = xoshiro128ss(a,b,c,d)
nodiv_rand2, state = xoshiro128ss(*state)
nodiv_rand3, state = xoshiro128ss(*state)
nodiv_rand4, state = xoshiro128ss(*state)
z3.solve(a >= 0, b >= 0, c >= 0, d >= 0,
nodiv_rand1 == int(rand1*4294967296),
nodiv_rand2 == int(rand2*4294967296),
nodiv_rand3 == int(rand3*4294967296),
nodiv_rand4 == int(rand4*4294967296)
)
I never heard about Z3
If you’re not familiar with SMT solvers, they are a useful tool to have in your toolbox. Here are some links that may be of interest:
Edit: Trying to fix formatting differences between kbin and lemmy
Edit 2: Spoiler tags and code blocks don’t seem to play well together. I’ve got it mostly working on Lemmy (where I’m guessing most people will see the comment), but I don’t think I can fix it on kbin.
If I understand the problem correctly, this is the solution:
a = 2299200278
b = 2929959606
c = 2585800174
d = 3584110397
I solved it with Z3. Took less than a second of computer time, and about an hour of my time – mostly spent trying to remember how the heck to use Z3 and then a little time debugging my initial program.
What I’d do is set up a simple website that uses a little JavaScript to rewrite the date and time into the page and periodically refresh an image under/next to it. Size the image to fit the remaining free space of however you set up the iPad, and then you can stick anything you want there (pictures/reminder text/whatever) with your favorite image editor. Upload a new image to the server when you want to change the note. The idea with an image is that it’s just really easy to do and keeps the amount of effort to redo layout to a minimum – just drag stuff around in your image editor and you’ll know it’ll all fit as expected as long as you don’t change the resolution (instead of needing to muck around with CSS and maybe breaking something if you can’t see the device to check that it displays correctly).
There’s a couple issues to watch out for – e.g. what happens if the internet connection/server goes down, screen burn-in, keeping the browser from being closed/switched to another page, keeping it powered, etc. that might or might not matter depending on your particular circumstances. If you need to fix all that for your circumstances, it might be more trouble than just buying something purpose built… but getting a first pass DIY version working is trivial if you’re comfortable hosting a website.
Edit: If some sample code that you can use as a starting point would be helpful, let me know.
Yeah; I also tried subbing in case that kicks off federation and searched a few titles to see if they ended up in random incorrectly as well (stuff like that happens sometimes with kbin). The magazine has seen a few microblogs mentioning the channel, and it clearly picked up the avatar/icon, description, etc. somehow, but doesn’t seem to be getting any videos as threads/posts and I couldn’t find any floating around disconnected either. I think kbin most likely doesn’t understand what PeerTube is publishing through AP, but there could always be federation weirdness or something.
Doesn’t seem to work right on kbin, unfortunately, although it does show up as a magazine: https://kbin.social/m/[email protected]

Any ways to get around the download failing
I did this incredibly stupid procedure with Firefox yesterday as a workaround for a failing Google Takeout download:
[1] You can actually replace the new .part file with anything that has the same size in bytes as the old file – I replaced it with a file full of zeros and manually merged the end onto the original .part file with a tiny custom python script since I had already moved the incomplete file to other media before realizing I could try this. (In my case, the incomplete file would still have been useful even with the last ~1MB cut off.)
There are probably better options in most cases – like Thunderbird for mailbox as other people suggested, or rclone for getting stuff from Drive – but if you need to get Takeout to work and the download keeps failing this may be another option to try.
I don’t have a complete solution, but I do have some ideas:
I’ve seen those posts too, but can’t speak German. What does “ich_iel” actually mean?
This does not work on kbin.social, unfortunately.
Wow, that’s a heck of a lot cheaper than I expected. I mean, it’s still more than I’m willing to pay for it on my own, but it’s not the “haha no way could I ever buy one” level of impossible I was expecting. My boss probably wouldn’t bat an eye if I asked for one to stick in a workstation… Hmm.
OK, that’s fun and all, but how much does that crazy SSD cost? :p

GLFW_USE_WAYLAND
and GLFW_USE_OSMESA
turned off to get it to try to build against X11.GLFW_BUILD_DOCS
, GLFW_BUILD_EXAMPLES
, GLFW_BUILD_TESTS
CMAKE_INSTALL_PREFIX
if you don’t want to use the /usr/local default install path.make
and make install
pkg-config --cflags --libs --static glfw3
to get this info as part of your own build process (in a Makefile, for example) or else require glfw3 as part of a cmake-based build, but you can read what’s generated in there if that program is not available to you for some reason. In case it’s helpful for comparison, what I get with a custom build of the static library version of glfw3 installed into /usr/local on a slightly old version of Ubuntu is output like -I/usr/local/include -L/usr/local/lib -lglfw -lrt -lm -ldl -lX11 -lpthread -lxcb -lXau -lXdmcp
but you may need something different for your particular configuration.Basically, something like this, probably, to do the compilation and get the flags to pass to g++:
wget 'https://github.com/glfw/glfw/releases/download/3.3.8/glfw-3.3.8.zip'
unzip glfw-3.3.8.zip
mkdir build
cd build
cmake -D GLFW_BUILD_DOCS=OFF -D GLFW_BUILD_EXAMPLES=OFF -D GLFW_BUILD_TESTS=OFF -D GLFW_USE_OSMESA=OFF -D GLFW_USE_WAYLAND=OFF -D GLFW_VULKAN_STATIC=OFF ../glfw-3.3.8
make
make install
pkg-config --cflags --libs --static glfw3
If you want to just compile a single cpp file after building and install, you can do something like
g++ main.cpp `pkg-config --cflags --libs --static glfw3` -lGL
I met a traveller from an antique land
Who said: Two vast and trunkless legs of stone
Stand in the desart. Near them, on the sand,
Half sunk, a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them and the heart that fed:
And on the pedestal these words appear:
“My name is Ozymandias, king of kings:
Look on my works, ye Mighty, and despair!”
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.
-- Percy Shelley, “Ozymandias”, 1819 edition

Try compiling GLFW from source against GLX instead of EGL. If glxinfo is talking to a software implementation running on your system, I’d expect GLFW built to use GLX would use the same implementation on your computer.
It’s not a GUI library, but Jupyter was pretty much made for the kind of mathematical/scientific exploratory programming you’re interested in doing. It’s not the right tool for making finished products, but is intended for creating lab notebooks that contain executable code snippets, formatted text, and visual output together. Given your background experience and the libraries you like, it seems like it’d be right up your alley.
