I’m taking my first algorithms class right now and it’s really cool to see a practical example of a binary tree and other algorithms! Thank you! I am confused by Huffman’s algorithm at 12:34 though. Is the 4th “A” supposed to be “01” or was the trailing 1 meant to be on the following “B”?

6:00 If you start throwing away bits from color information, always keep most bits for green because human eye is the most sensitive to lightness levels of green color. Always sacrifice blue color bits first, then red and only finally green.

Ohhh I always wondered why I've seen RGB565 encoding but never RGB655 or RGB556. Thanks!

[@arcaneminded]

The thing about "Always" is that there are always exceptions to the Always. Even this sentence.

[@kneesnap1041]

@@arcaneminded if this is how you treat words then there's no utility in having a word called "always", which is why I think this kind of thinking isn't very useful

[@giantnoah]

Even better, doom uses a limited set of 8 bit color palettes so you can get perfect color encoding in 1 byte per pixel.

[@muizzsiddique]

​@@kneesnap1041 Because we misuse language _all the time_ 😉. "Always" here is being used to describe a general instance of something happening, so you are bound to find special instances where the rule can't apply.

I don't normally make comments but man this video is beyond amazing.

And joy in his eyes through it all. Man is living his best life.

[@pacinpm2]

Doom was using 13h VGA mode which is a 256 colours palette mode. You could use this pallet directly instead of your own conversion to 1 byte. This way you don't lose any colours. Also if you Huffman encode blocks longer than 1 byte you could target patterns of colours from textures and potentially achieve greater compression.

[@ciano5475]

Or use LZ4 as compression

[@ThornOnARose]

The work put into this video is astounding. So happy to see Primeagen closer to where he wanted to be so long ago.

[@V.gara_]

Mustache man… I gotta say you really are the reason I stay inspired to code and continue to pursue the deeper understandings of development. The combination of pure unadulterated knowledge & passion for what you do is so inspiring. I’m already 2 months in using NeoVim becoming blazingly fast, finally able to sit still at my computer for 5+ hours & I now wake up everyday giddy knowing I GIT(😅) to learn more. I’m sure you hear this all the time, but you’ve truly saved my life. Thank you.

[@CrunchyBuncher]

[@acrosstheocean25]

That XOR frame compression technique is so cool! Really made me to start thinking about more good use cases for XOR. Good content as always, you are one of the biggest inspirations in my programming journey.

[@donko3005]

The point of doing fucking XOR operations is mind-blowing for compression Amazing

[@nullbeyondo]

Yeah, I was like, what's the point or how'd it compress shit? But then if the xor'd frame can construct the 2nd frame because it is mostly similar to it (repetitive pixel colors between frames for example!) and thus it mostly produces zeroes except the changed pixels... whao, it all clicked.

[@jonathanmarler5808]

DOOM renders into a 320x200 8-color bitmap. This means the colors DOOM actually renders already fit into 8 bits. It would be super easy to compile DOOM and make this framebuffer available to your compression stage.

[@einargs]

This is so awesome. I'm really glad you can spend more time on projects like this!

[@lolplayerlolz]

[@honeybunz3416]

Came here to say this as well. Since your message is already here, I'll like instead.

[@poweruser64]

I think the 1 on the end of the first line is supposed to be before it, it's even animated like it should be there.

[@the_briansparks]

This confused me as well, especially because prime specifically states that the same characters can never have different values, and yet on the screen that's *exactly* what's happening. I had to go back and rewind and figure it out and rewatch to learn.

[@mxmstrj]

[@soulwynd]

You gave me a blast from the past here. I used to program muds on the 90s and 2000s and my main bottle neck was bandwidth for hosting my game. I had to compress streams and use a lot of terminal hacks to get my ASCIi maps to work fast. I could even play videos on the terminal in ASCIi all with low bandwidth and gzip compression.

[@re_detach]

0:09:07 thank you for re-explaining how XOR has memory; I didn't get it the first few times you mentioned that but this video really helped solidify that concept!

[@lukusridley]

The "I've done it before but I didn't know the name" experience is such a powerful programming vibe. Encounter algo named wave function collapse; discover I had implemented it before by accident. Run-length encoding vs "Just count how many times things show up". Great vid

[@apIthletIcc]

Gotta admit, it was today that I finally fully understood XOR lol Also thanks for this... really helped me come to a breakthrough with reverse engineering some stuff. Basically been trying to figure out the cause of some corrupted frames in KZbin videos and now I can see why it's happening but now I need to figure out why it's only on certain videos, and only when using certain phones. New phone doesn't get the corrupt frames, but three previous phones I had do get them. One of the new and one of the old are the exact same device model, under different carriers. And the corrupt frames, they only occur on the three old ones when on WiFi. I tried a different wifi router, and it doesn't happen. I had a compromised router! [ISP redacted] might have an announcement to make soon..

[@1000_Gibibit]

An encode/decode stack is one of those things I just gotta implement sometime. So useful! For a second I didn't understand what was going on with the min-heap but it all came together in the end. Great way to make a fun video educational too, thanks Primeagen.

This was good, great style of content for you. Nice job on the compression, nice explanation for the xor trick.

[@Jacobk-g7r]

The funny thing about what you did is you basically simulated the same thing as a brain. It’s sifts and weighs the options but uses the data from the sensory tools to construct understanding and that leads to guidance. Wild that maybe the way the worlds pressures form our habits and guides us might be able to be understood by just experiments like this. Good work. What i mean is that the brain uses the data to think like how your people can send in actions and stuff and the ai does what it does. Haven’t watched fully yet but your beginning 0:49 got me thinking.

[@teddyamkie7706]

The best explanation ive seen for what actually gets done to make efficient code along with the process. Two things im curious on your take: 1) using edge detection and morphological operations for further efficiency since theres a lot of patterns that can be known of neighboring bits 2) client side prediction using player input to process known data on the client side. When youre walking towards a dark step on the stairs, it coming more into vision and getting brighter can happen client side. Server side, you're only looking for deltas that cant be assumed by the client.
