Had my first real use case for C++ "volatile" in a long time.
Need to wait for an event to happen to unblock threads, but cannot talk to the process (=devkit) in any way, only from the outside (=PC).
Event to happen is set by changing a certain memory location from the PC.

Thanks for that amazing feedback, keeps me motivated!

I don't understand why a RTTI library would have to make string *allocations*.
It's all statically typed, the library should only be using string literals which are compiled into the ELF.

There is Live++, which is completely generic and works for C++ code in any project, including Unreal, Unity, and Godot.
For Unity, it's used by studios with access to Unity's source, and studios that build .dlls using C++ for performance, which is then used by C# code.

Completely agree.
By the time UE5 editor has opened on my PC (a 64-core Threadripper), I have already made 10+ changes in my own tech, including C++ code.

I think most game dev teams underestimate how damaging slow workflows are to the ultimate quality of their game.

If it takes 5 minutes to launch the game and see your changes, I think your game is going to be MUCH worse than the alternate timeline where it took 1 minute

For what I'm working on, I can change every file, asset, shader, and C++ code and see the changes in <1s.

Shaders take roughly 100ms, C++ code 500ms.

Using my own custom tech and Live++.

To me, Mathias Gidsel really is the GOAT. Such joy watching him play.

6 assists and 7/7 against that defense. Just amazing how agile, dynamic and intelligent his play is.

In math terms it's completely clear though: percentages work with base values, so adding e.g. VAT gives you a new *base* value from which you deduce a percentage, but that percentage needs to differ, because the base is different.

That's generally not really understood with percentages.

E.g. people know that we have 20% VAT here in Austria, but are often confused when some store runs a discount with "don't pay VAT" because they think you pay 20% off the net price, but it's actually 16.6% off.

Great writeup, thanks!

Spinning around: Please don't! - siliceum Embark on a journey about why you should sometimes trust your OS more than yourself.

Ever wrote spin-locks or had to debug them?
I have, and I got tired of seeing (and writing) crappy ones, so I did a real investigation this time.

Spoiler: trust your OS.

Still need to put it onto the front page, forgot that!

I guess we are doing this again:

@jbikker.bsky.social Just wanted to say thank you for your ray-tracing blog series.
I needed a refresher for how everything works underneath, and your articles were super informative and well written.

Thanks!

Disgusting.

Ever since I attended Devcon in Cologne, the amount of spam I receive has skyrocketed like crazy.
I'm still apparently "subscribed" to dozens of dubious newsletters.

Always a good idea ;)

Code is a different story, unless you absolutely planned for it from the start.

Engines that don't have hot-reloading for all data hopefully no longer exist.
It's not that hard.

These were things that weren't so easy for me to get stable 15 years ago. I had a much harder time understanding APIs and their concepts behind them.

The resulting code I wrote also is *much* shorter than what I had.

It's amazing to feel for yourself what a difference 15 years of experience make.

Most of it feels easy and natural these days.
An atomic here, a thread there, some job system in between, async I/O, 100% rock-solid hot-reload using ReadDirectoryChangesW.

Started working on a bit of game/engine tech over the holidays, had a look at Molecule. Found some good bits, but am also on a completely different experience level now.
Whipped out a completely async, jobified, hot-reloadable asset manager using I/O completion ports in 10 hours.

Literally had to run this last week because kept waking up for no apparent reason.

UIforETW is No Longer a CPU Hog A few months ago I wrote about how many processes on my system were waking up and wasting CPU time for no good reason, thus wasting battery power, electricity, and CPU power. I was surprised that n…

Can I just get everybody to read this blog post and apply it to their own programs?

Happy holidays everyone, see you in 2026!

Feels like this would be something where it's worth looking at the generated assembly code, as well as play around with likely and unlikely annotations.

Same here!
There's a VGA version as well.
