What was your last RTFM adventure? Tinker this, read that, make something smoother! Or explodier.
As for me, I wanted to see how many videos I could run at once. (Answer: 60 frames per second or 60 frames per second?)
With my sights on GPUizing some ethically sourced motion pictures, I RTFW, graphed, and slapped on environment variables and flags like Lego bricks. I got the Intel VAAPI thingamabob to jaunt by (and found that it butterized my mpv videos)
$ pacman -S blahblahblahblahblahtfm
$ mpv --show-profile=fast
Profile fast:
scale=bilinear
dscale=bilinear
dither=no
correct-downscaling=no
linear-downscaling=no
sigmoid-upscaling=no
hdr-compute-peak=no
allow-delayed-peak-detect=yes
$ mpv --hwdec=auto --profile=fast graphwar-god-4KEDIT.mp4
# fucking silk
But there was no pleasure without pain: Mr. Maxwell F. N. 940MX (the N stands for Nvidia) played hooky. So I employed the longest envvars ever
$ NVD_LOG=1 VDPAU_TRACE=2 VDPAU_NVIDIA_DEBUG=3 NVD_BACKEND=direct NVD_GPU=nvidia LIBVA_DRIVER_NAME=nvidia VDPAU_DRIVER=nvidia prime-run vdpauinfo
GPU at BusId 0x1 doesn't have a supported video decoder
Error creating VDPAU device: 1
# stfu
to try translating Nvidia VDPAU to VAAPI – of course, here I realized I rtfmed backwards and should’ve tried to use just VDPAU instead. So I did.
Juice was still not acquired.
Finally, after a voracious DuckDuckGoing (quacking?), I was then blessed with the freeing knowledge that even though post-Kepler is supposed to support H264, Nvidia is full of lies…

and then right before posting this, gut feeling: I can’t read.
$ lspci | grep -i nvidia

# ArchWiki says that GM108 isn't supported.
# Facepalm
SO. What was your last RTFM adventure?
I have been burnt too many times by vendor incompatibility at work to not read the manuals before deploying something.
I think it was using the Void Linux package manager.
I was trying to write a custom Strategy for an objectMapper in Java. Foolishly decided to ask ChatGPT about it and got instructions which suggested an implementation that was the inverse of how Strategies actually work. Stuck for an afternoon.
Then in the evening I read the docs and put it together in half an hour from scratch. Lesson learned about the stochastic parrots.
Hah, stochastic parrots.
Makes me wonder. Every laziness I’ve had with the vector guessers, I’ve seen an exact counterweight.

| Here’s random code. Pray it works | Free ancient code at man 3 getifaddrs. |
| How does this API work? (when the API has below 10 million sample lines of code) | Incredibly concise documentation worth spending 2 minutes on or HTML text without margin lines worth spending 20 minutes on |
| Maybe this is what’s causing your bug. Investigate a, b, and c. Conclusion sentence. | footnote in ArchWiki / archetypal 2009 StackOverflow duplicate |
| Here’s the main idea of X… you need to take into account a combination of facets to ensure safety. | Angry blog post about X that’s oddly technical (now you see both sides) |
One, you can invoke more often (throw ChatGPT configs against the wall until it doesn’t error); the other you can invoke more deeply. So I can’t help but wonder – when we cancel out all the terms – if the timesaving sum is positive or negative. ¯\_(ツ)_/¯
I learned that rpm-ostree cant remove packages from an OCI image, ever.
So even if I have a blue-build process for example in secureblue removing Firefox, it is just removed on my side, locally. Thats why I cant reinstall it.
Instead of learning about all the Flatpak packaging conventions, I just translated the docs!
for me it usually goes
me: reads the manual, fails, then asks for help
person helping: heres a canned tip
me: didnt help
person helping: you should read the manual
me: no i am beyond that, i need help with my problem
person helping: oh turns out i couldnt actually help you, anyways go try somewhere else
