What was your last RTFM adventure?

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)

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


<span style="color:#323232;">$ 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

</span><span style="color:#183691;">Error creating VDPAU device: 1
</span><span style="color:#183691;"># stfu
</span>

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 , Nvidia is full of lies…

and then right before posting this, gut feeling: I can’t read.

SO. What was your last RTFM adventure?

Albbi ,

Never used Kubernetes before, but really wanted to get into it with this new project. Project already has docker-compose. Found a converter to Kubernetes. Ran it and it mostly worked, but I had to dive into a week of reading the documentation and testing to get the rest of the way there.

One of the largest projects under my GitHub account is an attempt at a proof-based programming language that I had to abandon because I underestimated the theoretical work involved, did not RTFM enough and months into it realized the entire thing was unsound af.

I tried to install ROCM on my machine to run Stable Diffusion. So far I’ve managed to bork my system to the point of having to reinstall.

Im_old ,

I’ve installed ROCM before reading that my AMD GPU does not support it

russjr08 ,

I’d recommend using ROCM through a Distrobox container, personally I use this Distrobox container file and it has suited all of my needs with Stable Diffusion so far.

That is, if you’re still interested in it - I could totally understand writing it off after what happened 😅

Diplomjodler3 ,

Thanks, I’ll look into that.

No mention about the limited API in the Nessus Professional documentation.
Waste of time trying to test API, debbuging why some method doesn’t work.

confuser ,

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 somewhwre else

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!

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.

fool OP , (edited )

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 think it was using the Void Linux package manager.

I have been burnt too many times by vendor incompatibility at work to not read the manuals before deploying something.
