Mysterious lights over Brandon, MB tonight were light pillars, a phenomenon seen when ice crystals align horizontally in the calm air like tiny mirrors. It appears the lights are beaming straight up into the sky, but, like many things, it's "all in the eye of the beholder."

The ICLC 2025 (International Conference on Live Coding) website is now live! It will take place in Barcelona at the end of May, and a lot of people are hard at work making it happen. @toplap_bcn iclc.toplap.org/2025/index.html

The call for submissions for the International Conference on Live Coding (ICLC) is now: Live! The conference will be held in Barcelona, in May 2025. Besides submissions of papers, performance and workshop proposals, we're also looking for reviewers. iclc.toplap.org/2025/

@tvaneerd Rename variables to be clearer and more descriptive. If some longer expression (e.g with container element accessing, or a chain of struct member accessors) is being used multiple times in a block, replace with a (const when possible) reference to the specific thing.

What are some good simple coding habits, like - declaring variables where they are first used Maybe habits that you do when trying to fix/understand code and your first step is to just declutter and clean and once you are done the code suddenly is easy to understand.

@parityprime Marking menus have been around for (at least) thirty years; the first time I remember seeing them was in Maya. For more, check out: billbuxton.com/MMUserLearn.ht…

experimenting with a potentially superior way of utilizing the right mouse button. right click and hold -> then flick your mouse in one of 8 directions to do a thing feels so much faster, more efficient, and natural

@PounceLight @OdaTilset Congratulations @PounceLight on the Tiny Glade demo, it's a beautiful thing, I just want more space to create... Looking forward to the final game/experience.

Tiny Glade DEMO is OUT on Steam🏰🐑✨🎉 We'll be spying on all of your creations 👀🤩 Feel free to tag us or mention #TinyGlade. We'd love to see what you make! We hope you have a good time 🙌 PS: sound on to enjoy @OdaTilset's new summer track🎶

Full points to @WriterYann for doing it both ways!

Or is it another case of North America rebelling against against the European way of doing things...? (except that UK-published English books also seem to go for "upright") There are a few exceptions, but very few (in my library).

I just noticed that my English-language books seem to have the spine text upright when the book is lying on its back, whereas Spanish (and French, Catalan) books seem to have it inverted! Does this mean something, culturally? 🤷‍♂

Bones navidats

@SebAaltonen Of course I will want Aurora Borealis (I'm from Canada), so I guess we'll have to use some LOD system with a secondary local coordinate system to represent the intricate detail of pine needles (<1mm thick), fine moraine rock (<0.125mm) and mushroom spores (even smaller). ;-)

@holaglen Clouds are needed at least. High clouds are 8km above ground. Airplanes up to 11km. That's +22km to the bbox size. If you want realistic northern lights, then that's +600km to the radius. 1200km to the bbox. Getting quite close to that 16384 already...

It's possible to model the whole earth (3d space) using 3x 32 bit integer (24.8 fixed point) coordinates. Most integer ops are full rate on GPUs (fp64 on RTX 4090 is 1:64 rate). This gives you 16384km range (need 12742km) and 1/256 meter precision (0.39cm).

@SebAaltonen Bah, who needs satellites? ;-)

@holaglen Yes indeed. You can get slightly bit better precision that way, but if you want to simulate airplanes and satellites too, then you need some extra range around the surface.

@ctford Really nice talk! (Also, sometimes live coding unintentionally leads to other kinds of birdsong... ;-)

@SebAaltonen This is affine idea!

We just changed most of our 4x4 matrices to 4x3 matrices (named Matrix4 and Matrix4Affine currently in our code base). Matrix4 * Matrix4 and Matrix4 * MatrixAffine return Matrix4. But MatrixAffine * MatrixAffine returns MatrixAffine. Matrix4 can't become affine...

I wish I were at @siggraph today for this panel on #preservingVR ! s2023.siggraph.org/presentation/?…

@lefticus I'm sure you've already come across this, but you should use "matchers" when comparing floating point numbers with Catch. github.com/catchorg/Catch…

#TFW you're doing Floating Point tests

@ryuichisakamoto Thank you for a lifetime of beautiful music.

@jasminezroberts @marknb00 @ARstories @skydeas1 @avibarzeev @auradeluxe @debfx @ImmersiveJourno @SkipRizzoVR @melslater True! Unfortunately a lot of pioneering people and projects, especially from those pre-smartphone, pre-web days, aren't really "recorded" in history very well. All we can try to do is access the old grey (and getting greyer) cells from time to time... blog.glenfraser.com/post/2019/a-qu…

we are unfortunately only *tech* subset that values influencers instead of the actual pioneers who will be in recorded history. h/t @marknb00 @arstories @skydeas1 @avibarzeev @auradeluxe @debfx @immersivejourno @skiprizzovr @melslater

fyi: modern #xr didn't start in 2013-14 with the google glass/oculus nor did it start in 2018 with a commercial head mounted retinal display nor did it start in 2021 with the widespread use of the term "metaverse" - it's been around since the 1980/90s

@DooleyMurphy Please explain your pedantology. (-;
