Context: O3DE is an open source (Apache 2) AAA game engine based on an updated Amazon Lumberyard I've had the opportunity to work with O3DE over the past few months at work and I'm very excited to see where it goes. There are two

I first came across this a while ago and after digging I found the way it worked (and possibly still works) behind the scenes is pretty cool: https://groups.google.com/g/emscripten-discuss/c/4Qw8OOgTvu0... &g

Yep, CCU = concurrent users. We look at CCU alongside number of entities in the sim, since they're both axes of interest for customers - 2m+ entity scale is tricky, netcode at 10k+ player scale is tricky, we target both. That said, I&#

Disclaimer: I work at Hadean, thought I'd clarify a couple of things Yes, the Hadean Platform is a general distributed compute platform. But 'EVE: Aether Wars' used Aether Engine, our spatial simulation engine built on top of

I worked on adding distributed compilation to sccache [0]. Docs at [1] and [2]. Compared to existing tools, sccache supports: - local caching (like ccache) - remote caching e.g. to S3, or a LAN redis instance (unique afaik) - distributed co

I highly recommend the 'interviews' part of this site [0]. Reading the honest opinions of professionals in this field helped me a huge amount when I was first digging into the internals of game engines and guided my thinking to un

I lightly used Godot before and using GDScript was a bad experience. It has some confusing semantics relating to reference counting and in-place modification (e.g. [0]) that make it really hard to use as a 'real' language (as oppo

Primarily because, until you mentioned it now, I wasn't even aware it was an option! That said, I generally shy away from shallow clones and probably wouldn't use it here: - it's a trap for people who ever want to work in tha

I sympathise a lot with this post! Git cloning can be shockingly slow. As a personal anecdote, clones of the Rust repository in CI used to be pretty slow, and on investigating we found out that one key problem was cloning the LLVM submodule

I can't comment on performance, but on a different note it seems to be generally accepted that 'real' container boot time is slow - fly.io mention this too [0]. To add some numbers: - 40ms for nsjail run an isolated command a

Similiar to GP, I too have been wondering about a Rc'd Rust. Unfortunately Rune and Dyon[0] are dynamically typed, which isn't so attractive to me. More promising are Gluon and Mun, both of which are statically typed. Of these two

Really happy to hear it's all going well, and I've been excited about V2 since I read the blog post about it - your product is awesome and solves a genuine need, and I really want you to succeed.

I'm kinda sad for you - I've been using and advocating zerotier for a while (it's amazing and indispensable)...but in my circles the word 'wireguard' has got people excited, which (anecdotally) is benefitting tailsc

This is great! I've been wanting to do something similar for a while, to call people out for making unfounded assertions - with the goal of trying to encourage more humility in making predictions. Will follow with interest.

comcast ( https://github.com/tylertreat/comcast ) is really helpful for simulating poor network connections. Particularly nice when used in Docker to do network simulations.

Can you clarify what youre referring to with "decided to implement it in the compiler instead", be it from this blog post or elsewhere? Clearly you need coroutines in the compiler, and the way Rust treats ownership means pinning i

One thing that may be non-obvious to people unfamiliar with Tcl is that it's syntactically a shell-like language, i.e. functions are invoked with a space-separated list of arguments and no parens. So `schro` on a line by itself execute

Fwiw, native-tls [0] is intended to solve this problem for the set of uses involving TLS (e.g. hyper [1], reqwest) by using the defacto standard on the platform you're on. This means no openssl is necessary on Windows. Longer term, I w

My 'favourite' bit of surprising (not undefined) behaviour I've seen recently in the C11 spec is around infinite loops, where void foo() { while (1) {} } will loop forever, but void foo(int i) { while (i) {} } is permitted to

One trick that helped when I was doing log crunching (where time parsing was a good 10%) was to cache the parse. All log lines began with a date+time like "2015-12-10 14:42:54.432" and there's maybe 100 lines per second. You
