I was reading an article in today's Washington Post about how analytics, and then optimization based on those analytics, has hurt the on-the-field/court product in MLB and the NBA, and holy crap, I felt like I was reading about D&D optimization!

My colleagues at TU Delft are seeking to hire a postdoc to work on Applied Planning and Scheduling under Uncertainty, with applications in modelling supply chain scenarios for offshore wind farm installation: https://careers.tudelft.nl/job/Delft-Postdoc-in-Applied-Planning-and-Scheduling-under-Uncertainty-2628-CD/814890902/
Gave a talk at the EURO OSS Seminar Series on "Data-Driven Algorithm Design and Verification for Parametric Convex Optimization"!

Big thanks to Dolores Romero Morales for the invitation!

One thing that can escalate really quickly with #gamedev is #optimization:
I am debating whether or not I should make this railing an asset with dedicated baked textures or use multiple materials and tiling textures.
A big advantage of the separate materials is: Tiling Materials can be re-used and because they tile they need smaller textures for the same sharpness.
A baked texture would save on geometry (thanks to normal maps) and draw-calls, when everything has the same material.

today with the help of some new elastic clips, i redid the fabric covers on our sofa. i am trying out using a set each of 2 long elastics and 4 short ones for both the seat and backrest. wonder how long the strips will retain their stretch for, and whether the covers will continue looking neat? :p

Surely someone's looked into this: if I wanted to store millions or billions of files on a filesystem, I wouldn't store them in one single subdirectory / folder. I'd split them up into nested folders, so each folder held, say, 100 or 1000 or n files or folders. What's the optimum n for filesystems, for performance or space?
I've idly pondered how to experimentally gather some crude statistics, but it feels like I'm just forgetting to search some obvious keywords.

In the YT video the young engineer optimizes the aim.
Modern neural networks are based on similar mathematical optimization principles (cost/loss functions)...

New post-doctoral research position in my group at University College London (#UCL), looking at the use of **optimization for the design of dynamic and flexible processes for electronic waste**, in collaboration with researchers in multi-phase and micro-channel flow experiments for process intensification and in model identification for the development of dynamic models. The eventual deliverable of this project is a demonstrator process with a digital twin. External collaboration includes both industry and two local councils, Newham Council in London and West Sussex County Council.
Closing date: 13 February 2025

As someone who learned programming in the early 80s on very limited machines (RAM measured in kilobytes, 1 MHz CPU), I had to learn to be careful about wasting memory and CPU cycles. This has served me well over the years as I always kept a close eye on optimizations.
So I'm very pleased to see the DeepSeek folk are continuing this tradition.

Over-relying on trigger volumes for interaction when simpler solutions are available can hurt performance. Use raycasting or simpler conditions when appropriate. #Unity3D #performance #optimization #gamedev
Leaving project settings unoptimized for the target platform can result in suboptimal performance. Adjust settings for lighting, physics, and rendering early on. #Unity3D #optimization #performance #gamedev
Leaving default import settings for models and textures can bloat your game and cause performance issues. Always review and optimize import settings. #Unity3D #optimization #performance #gamedev
I offered this deal about a year ago, now I’m adding the latest book to it:
For a limited time, you can get all 5 ebooks of the “Upgrade Your HTML” series (which is all about HTML optimization and minimalism) nearly for the price of 1, over at @leanpub!
Forgetting to optimize terrain generation for large worlds can lead to poor performance and long loading times. Use terrain LOD and occlusion culling for better performance. #Unity3D #optimization #performance #gamedev
Leaving unnecessary scripts or prefabs in the project folder will clutter your workspace and slow down project loading times. Regularly clean up unused assets and scripts. #Unity3D #optimization #bestpractices #gamedev
Not optimizing your game for various hardware configurations can result in poor performance for players with older devices. Always test across a range of hardware. #Unity3D #performance #optimization #indiedev
