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

SO. What was your last RTFM adventure?
For me, it was getting a handle on rsync for a better method of updating backup drives. I was tired of pushing incremental changes manually, but I decided to do a bit of extra reading before making the leap. Learning about the -n option for testing prior to a sync has saved me more headaches than I’d care to enumerate. There’s a big difference between changing a handful of files and copying several TB of files into the wrong subfolder!
Oh I love the “walk me through what I’m about to do” concept. Dry runs should be more common – especially in shell scripts…
The world would be a better place if every install.sh had a --help, some nice printf’s saying “Moving this here” / “Overwrite? [Y/N]”, and perhaps even a shoehorned-in set -x.
Hope your r/w wasn’t eaten up by the subfolder incident (that I presume happened) :P
Not my last, but after using killall in Linux, I tried it on hpux, only to discover and later confirm in the man page that on hpux it doesn’t take any arguments, it just kills every process.
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
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.

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!
