rperez333··on Why Apple's Severance gets edited over remote desktop software
I was always curious about its performance. How is the latency compared to alternatives like Parsec, HP Anywhere or NoMachine?
rperez333··on Apple M3 Ultra
Content creation usually, which consists of audio, photo, and video editing mostly. The hardware and software integration makes video editing on a Mac really superior, specially with their ProRes codec.

You can get a good experience on a Windows or Linux machine with DaVinci Resolve, but that’s mostly because of the way better GPUs like the 4090/RTX series you’ve got at your disposal.

rperez333··on C++ is an absolute blast
Question for pros: I'm a Python dev who recently started diving into C++, hoping to build plugins for DCCs. However, every time I read these threads, I feel as if I'm on the completely wrong path. Positive views like the OP's are rare.

While I understand that not everyone gets to work on a John Carmack level codebase, is working on a C++ project really as challenging and unrewarding as it seems? Is the productivity that low, and do every step feel so difficult that they eventually drive developers away?

rperez333··on Canada 'sleepwalking' into cashless society, consumer advocates warn
Most countries should study the Brazilian system called Pix. It's faster than Interac, controlled by the central bank and very accessible to its population. https://www.bcb.gov.br/en/financialstability/pix_en
rperez333··on Why not just do simple C++ RAII in C?
I know nothing about Zig, but this is pretty interesting and looks well designed. Linus was recently very mad when someone suggested a new semantics for overflow:

—— I'm still entirely unconvinced.

The thing is, wrap-around is not only well-defined, it's common, and EXPECTED.

Example:

   static inline u32 __hash_32_generic(u32 val)
   {
        return val * GOLDEN_RATIO_32;
   }
and dammit, I absolutely DO NOT THINK we should annotate this as some kind of "special multiply". —-

rperez333··on Re-creating Disney's sodium vapor process [video]
Because it creates more problems than it solves. A movie set is expensive and moves fast – and keying is not as big of a problem as they made it out to be.

For example, Niko doesn't seem to be aware of the IBK keyer (based on his comments in the VFX subreddit), which is the keyer used on almost every shot in high-budget movies. While it's not a single-click solution, it's the main tool to tackle thousands of shots with defocused edges, motion blur, and semitransparency every year.

Niko deserves credit for bringing Paul's incredible experiment, but Corridor is at its core a group of entertainers, and most of them have never had experience in a large production/VFX environment. Take everything they present with a grain of salt.

rperez333··on OpenAI: Sora: First Impressions
I'm seeing shots that would be incredibly expensive for some productions - even if we ignore the ones requiring visual effects work. Some of them would need small crews, permits, rentals of expensive equipment, casting, and travel. It's impressive and concerning at the same time.
rperez333··on Genesis of a New Programming Model
Looks like Temporal and Prefect had a baby. I hope this gets traction and best luck to the team.
rperez333··on Are We Wayland Yet?
Is there any i3wm alternative that works with Wayland on Nvidia hardware (proprietary drivers)? I tried Sway and Hyprland last month but found neither ready for daily use.
rperez333··on IDEs we had 30 years ago
The terminal window from VSCode still gives you all of that, with some extra ergonomics from the GUI. No need to remember ctrl b + % to split a Tmux window, scrolling and find just works, no need to install plugins to save sessions.
rperez333··on Stable Video Diffusion
If a company train the model from scratch, on its own dataset, could the resulting model be used commercially?
rperez333··on Google's advanced music generation model and two new AI experiments
This already happens with chess - despite the machine being superhuman, people have never been more attracted to the human game.

Perhaps what will happen is that we will have more time to play/watch more?

rperez333··on Beyond Memorization: Violating privacy via inference with LLMs
The GDPR in Europe doesn’t allow you to use publicly available information without explicit user consent, especially if involves personal data. Even doing some Google Analytics can in theory result in large fines.
rperez333··on I designed my own keyboard layout. Was it worth it?
I went through this rabbit hole about 2 years ago. I assembled 2 versions of also 34 keys designs, split, low profile keyboards. That helped a lot with my RSI but eventually my thumb got stressed since is constantly requested for the layers.

I eventually assembled a design with a few more keys, pretty similar to the Voyager.

I switch between this and the Microsoft Sculpt, and it definitely helped me with the constant discomfort.

rperez333··on Judge pares down artists' AI copyright lawsuit against Midjourney, Stability AI
Because most people prefer spend their free time consuming art instead of staring at a wall. You just forgot that art embraces games, music, movies, tv shows, comics, books or even some Youtube.
rperez333··on Why is it so hard to make digital fire look good?
Pixar/Disney used AI to enhance their latest Elemental characters. They did a technical presentation 2 months ago month at Siggraph: https://dl.acm.org/doi/abs/10.1145/3587421.3595467

There are videos showing the results with/without the AI detail pass.

rperez333··on How to draw software architecture diagrams (2022)
What would be a good library /tool to auto arrange a complex graph (DAG) like the Blender/Unreal/Houdini node interfaces?

I would expect some options to set constraints, like the first input staying always aligned with the previous node.

Here is one of these DAGs: https://cdnb.artstation.com/p/assets/images/images/026/099/2...

rperez333··on First 96-Core AMD Zen 4 Threadripper Tests Show Utter Domination over Intel
Most of the high-end 3D work is rendered on CPU render farms, specially due to how large and complex the scenes are.
rperez333··on Log is the "Pro" in iPhone 15 Pro
Even high-end cameras that can shoot in Log, like the Sony A7 series, apply some noise reduction on their end. This is important for most compressed formats.

However, most people would be horrified to see how noisy and unsharp the images from top cinema cameras are when most post-processing is disabled.

rperez333··on Visual Node Graph with ImGui
I would also love to have an auto layout that considers more than just uncrossing lines. I spent some time trying to find a solution for organizing Nuke node graphs (for VFX) that would follow a few additional rules, but I didn't get very far. Not a perfect example, but getting something along these lines would be ideal: https://headjack.io/wp-content/uploads/2017/07/Huge_script-1...
rperez333··on AI and the End of Programming
They are already doing it: most humans are not capable of writing a program to drive a car, be an interesting talking companion, or even remove noise from audio. We still need humans to kickstart the learning process, that’s true, but even them are not the programmers we are used too.
rperez333··on Marvel Visual Effects Workers Vote to Unionize
Because it’s easy to shift VFX work to another location. Even a decade ago, VFX studios were popping up almost overnight in Vancouver. All you needed was to rent some space and thin clients. Today we barely need to rent any space.
rperez333··on FFmpeg Patches for a 20% speedup of Apple ProRes decoding
Ffmpeg is used frequently, but not for masters. The finishing part is done under softwares like Baselight/Resolve/Nucoda, and that's when the color is baked. If a ProRes is required, usually it comes out from them. src: I work in a pipeline of a large VFX studio.
rperez333··on The Rimac Nevera Has Broken the Production EV Nurburgring Lap Record
There's one selling for $4.1 right now. https://www.jamesedition.com/cars/rimac/nevera/rimac-nevera-...
rperez333··on Overworked and underpaid, VFX workers vote to unionize at Marvel
Scott Ross, founder and former CEO of Digital Domain, spoke for years about this. The issue is there are just a handful of film studios capable of keeping a large VFX facility busy, so they have a lot of leverage when negotiating contracts and setting prices.

Because that part of the film process can run offshore, VFX studios find themselves fighting for these contracts and/or accepting unadvantegeous terms. I remember him saying that film studios can strong arm a VFX facility to open in a place under heavy tax breaks, and they are expected to 'forward' the cost savings.

rperez333··on Netflix invents new green-screen filming method using magenta light
Netflix acquired one high-end VFX studio recently - Scanline. A lot of the compositing work is edge integration, so this could in theory translates in cost savings on their pipeline.

Also, this research is under the supervision of Paul Debevec, who spearheaded more than 20 years ago the image-based lighting and high dynamic range workflow used in virtually every single production now. If we see chrome balls in film sets, it is because of him!

That said, I don't think this will find its way on sets, mostly because DOPs/directors are very precious about the way they capture their images. The alternative they offer in the paper, using a reduced shutter speed and adding synthetic motion blur, is also a big ask - with the added problem of syncing the cameras to the lights, which would slow production.

In my experience, extracting the alpha is not an issue - compositors can get close to the GT using old tools/algorithms. However, getting the original colour around the semitransparent areas is the biggest hurdle - and each artist uses a bunch of approximations and local fixes, which are very time-consuming. Recoloring the edges would be enough to revolutionize this workflow. Given their virtual stage + deep learning technology, they are in a good position to make this happen.

rperez333··on Netflix invents new green-screen filming method using magenta light
Actually, checking the paper, they tested that - reducing the shutter speed, realigning nearby frames and adding motion blur. As a vfx compositor, while I’d be OK with this workflow, it doesn’t come without their own issues and artifacts.
rperez333··on Netflix invents new green-screen filming method using magenta light
Movies are captured with a good amount of motion blur, so this unfortunately doesn’t work.
rperez333··on CodeT5+: Open Code Large Language Models for Code Understanding and Generation
Introducing CodeT5+, a new family of open-source code LLMs for both code understanding and generation, achieved new SoTA code generation performance on HumanEval, surpassing all the open-source code LLMs.
rperez333··on Algorithms to Live By – The Computer Science of Human Decisions
I’ve read years ago, and became my comfortable keeping my inbox or my files become messier, relying more on the search. I wish Google Desktop would still exist, however.
