Last update was Feb 5th, it traveled around 2 hours north and the AirTag is still living near the beach, but not that close anymore. I wonder if it’s happy there and if I’ll ever hear from it again

Yes, thanks for pointing out! both have batteries

Obrigado Favaaa Nós fizemos a visualização, não os efeitos especiais. Faz parte de VFX, é o início da produção virtual Também demos uma palestra na Unreal Fest sobre isso se alguém quiser ver: www.youtube.com/live/s1qdbJt...

Hahahaha se o pobre AirTag tava atrás da gente eu acho que desencanou e foi aproveitar a vida na praia

My wife lost her AirTag at Costco last year. It went to San Francisco and now it’s living in Malaysia

Thank you! It's pretty awesome that you're interested in this. I wish I could go back and list all the games I've worked on. It all changed when Apple and Google came with the iPhone and Android. I would have never thought Nokia and Sony Ericsson would disappear

Nice! I worked with porting. So I started with simple J2ME > J2ME then I went to more complex like Java <> C++, iOS native to EA Mobile Tech and a weird french console called Freebox. But I worked on a lot. Some: Dragon Quest I&II, Castlevania, Samurai Showdown(for HipTop), Real Racing 2, Monopoly

Rogério Tavares Gasi @rodja.bsky.social · 08/01/2025

I spent years of my life making games for these devices. J2ME and BREW. Seeing this photo made me happy and gave me a huge nostalgia.

More info. I also checked how much faster it is when the number of files you match is drastically smaller. I compared two scenarios: a > 95% match and a < 0.6% match. The difference is not huge, but some methods, like glob, have a more significant difference. #profiling #python #filesystem

The image contains four bar charts comparing the performance of different Python methods for finding files, with the bars representing overlapping metrics. The numbers 1, 2, and 3 on the x-axis correspond to the system's file sizes: 1 (45,000 files), 2 (360,000 files), and 3 (3 million files). The bars indicate the time it took to find files with a match range of >95% and <1%.

Top Left: Glob 99% Match vs <1% Match

Two overlapping bars per file size:
The larger bar represents the time taken to find files with >95% match.
The smaller bar represents the time taken to find files with <1% match.
As file size increases, the time for >95% matches increases significantly.
Top Right: OS Walk 99% Match vs <1% Match

Similar overlapping bars per file size:
The taller bar shows the time taken for >95% matches.
The shorter bar shows the time for <1% matches.
The growth in time with increasing file size is evident, but less dramatic than Glob.
Bottom Left: Pathlib 99% Match vs <1% Match

Overlapping bars per file size:
The >95% match bar is consistently taller than the <1% match bar.
The increase in time for larger file sizes is steady but not as steep.
Bottom Right: Listdir 99% Match vs <1% Match

Two overlapping bars per file size:
The bar for >95% matches is tallest, especially for the largest file size (3 million).
The bar for <1% matches is relatively short.

The image is a line chart titled "Speed Improvement When Finding Less Files (95% found vs <1% found)". It compares the percentage speed improvement of four different Python methods for file searching as the number of files increases. The x-axis represents three file sizes: 45k files, 360k files, and 3 million files, while the y-axis shows percentage speed improvement ranging from -10% to 15%.

Key Details:
Lines Representing Methods:

Glob (% faster): A solid blue line that starts near 0% at 45k files, gradually increases, and shows a steep rise to about 15% improvement at 3 million files.
Pathlib (% faster): A dotted orange line that starts slightly above 0% at 45k files and rises steadily but remains below 5% improvement at 3 million files.
OS Walk (% faster): A dashed green line that remains relatively flat, showing a consistent improvement of around 5% across all file sizes.
Listdir (% faster): A dashed blue line that begins slightly below 0% at 45k files, dips further down near -5%, but rises sharply after 360k files to reach around 10% improvement at 3 million files.
Trends Observed:

Glob and Listdir: Show significant speed improvements with larger file sizes, with Glob having the highest improvement at 3 million files.
Pathlib: Steady improvement with smaller gains compared to other methods.
OS Walk: Consistent performance across all file sizes, with moderate gains.
Negative Speeds: At smaller file sizes, Listdir experiences a slight negative speed improvement (around -5%), indicating slower performance compared to other methods when finding <1% matches. This trend reverses for larger datasets.

I was wondering which method was faster to iterate through files in #python and find all files of a specific extension. So I tried glob, pathlib, os.walk, and a listdir + a recursive function. Here's how long it takes (in second), for different sizes of file systems. os.walk is the fastest method

A graph showing the table

45k Files 360k Files 3mi Files
glob 10.68 100.57 546.61
pathlib 9.79 91.51 486.68
os.walk 6.51 60.9 318.19
listdir + recursive 10.33 89.82 537.34
Found Files 57 450 17919

How to build an optimization toolbox

“Optimizing a game” and “developing a game” are two activities that tend to blur together. And while you probably have an elaborate toolbox for developing your game, when it…

Nice! Same overall pipeline as us, but we use UE mostly, and we’re trying to animate in engine in some projects.

Rogério Tavares Gasi @rodja.bsky.social · 31/12/2024

Oh I see! So animation was done in Maya or similar and then imported into Frostbite?

Rogério Tavares Gasi @rodja.bsky.social · 31/12/2024

That’s pretty interesting! At Halon those are usually two separate things, the layout folks would need to ask for the technical animator for help. Do you feel like doing both helped the overall production?

Rogério Tavares Gasi @rodja.bsky.social · 31/12/2024

Fantastic work, @deremix.bsky.social ! Thanks for sharing! I enjoyed all of these shots when playing the game. I’m happy to find you here! I do have a quick question: as a cinematic designer, do you think your work is similar to a layout artist? Or is it something different?

According to #AI, the #universe is much smaller than I thought.

A Google search of "number of atoms in the universe" shows the following AI answer: The number of atoms in the observable universe is estimated to be between 1078 and 1082 atoms. This number is a rough guess based on a number of assumptions and approximations, but it's unlikely to be too far off the mark.

If you look at semantic versioning this make sense if the product was not public yet: Major version zero (0.y.z) is for initial development. Anything MAY change at any time. The public API SHOULD NOT be considered stable.

And to add a note here, when you have a table of tasks and dependencies you can make a critical path. Once you have a critical path, then you most likely be able to parallelize tasks and start naturally getting floats or slack times that you can use to avoid having to do crunching

I’m learning about optimal stopping. It’s a great way to know when to stop looking and start choosing things. What things? Well, any things! A relationship, an employee, a house, which game to develop, which publisher to choose from, etc. And there are variations! sites.cs.ucsb.edu/~suri/ccs130...

And it’s almost on the latest version of ImGui! Thanks!

Rogério Tavares Gasi @rodja.bsky.social · 21/12/2024

Lucid take on the topic. AI is also another tool in the toolset of good developers. For example: sometimes it might be easier to specialize a LLM to extract data than to write a parser.

Mostly what I can conclude is that the academic folks used to think that the environment changes would be happening maybe in the lifespan of their grandchildren, but they all came to realize that they would be affected by it themselves

Random Tip 005 on #UnrealEngine #DearImGui is awesome and there's a plugin: github.com/segross/Unre... However, it's not updated for a while. It has version 1.74 while the latest on DearImGui is 1.91.6 So until a hero updates this lib to UE 5.x you're going to have to make some changes yourself!

Random Tip 004 for #UnrealEngine In #VisualStudio, you might find a file you need and want to check adjacent files, but the solution explorer doesn't update. Make sure you check the "Track Active Item In Solution Explorer" under Tools > Options > Project and Solutions > General

Screenshot of the Options dialog in Visual Studio with the option "Track Active Item in Solution Explorer" highlighted with a red square
