Beautiful Type Erasure with C++26 Reflection
If youβve ever tried using type erasure for something more complicated than std::any or std::function, youβve either written 100+ lines of easy-to-mess-up code or reached for a boilerplate-heavy library like Boost.TypeErasure or Folly.Poly. rjk::duck usesβ¦

cpp2 (cppfront) is over?
I haven't used cpp2 (cppfront) much, but I like the idea of it: consistent syntax, consistency of meta-programming (which is done in C++ too, I believe). Herb Sutter presented cpp2 (cppfront) as an experiment. He did not encourage other people to bet on it, exactly. And there wasn't much activity since 2022. Is the experiment over?

fun fact about string literals i often forget:
String literals in c/c++ (const char*), support operator\[\] (in a compile time context)!
>constexpr char first = "test"[0\];
// i.e first = 't'
I think 90% of C developers would know this, but I figured maybe those of you who didn't start out with C might not have discovered this! I just recently used this in combination with an X macro for some debug ui code:
>// the x macro in question
\#define LIST_NOISE_PARAMS
X(heat)
X(rain)
X(cont)
X(grad)
X(hills)
I wanted to display the first letter of the noise parameter's name, in caps, followed by the noise value, i.e:
>H: 1.00
(the heat noise = 1.0f.)
>\#define X(VAR) UI::Text("{}: {:4.2f}",#VAR[0\]-('a'-'A'), sample.VAR);
LIST_NOISE_PARAMS
\#undef X
>// expands to:
UI ::Text("{}: {:4.2f}", "heat"[0\] \- ('a' - 'A'), sample.heat);
UI ::Text("{}: {:4.2f}", "rain"[0\] \- ('a' - 'A'), sample.rain);
// ...
>// which evaluates to:
UI ::Text("{}: {:4.2f}", 'H', sample.heat);
UI ::Text("{}: {:4.2f}", 'R', sample.rain);
// and so on for the rest of the list!
What other 'odd' C/c++ tricks/facts do you guys know/use? Personally, the X macro technique blew my mind when I first discovered it, and its probably the most legitimately useful 'trick' I know of. Pretty cool. Hopefully there are others in here that enjoy these little tidbits as much as i do.

A hardware-informed guide to Modern C++.
It explains how the source becomes instructions, how memory works, and why the machine cares about your choices.
If you're interested in systems programming, game engines, HFT, or writing fast software, give it a read.

Floating-Point Error Handling in C++: What Actually Works - Johnny's Software Lab
Floating-point errors are unavoidable, but how you detect and handle them can make the difference between clean, high-performance C++ code and a debugging nightmare. In this article, we explore the practical techniques for handling NaNs, infinities, and otherβ¦

Programs, Not Objects: How I Stopped Designing Architecture and Started Writing a 3D Editor
Todayβs post is a bit different from my usual deep dives into mesh geometry. Itβs a story about architecture β and about going back to the beginning. Think back to how you learnedβ¦
What do you think do I need continue learning cpp
Actually it's more about what would we need for cpp to be more popular
I personally think cpp is great language even thought I am getting bullied by compiler every single time or does my code classified as harassment/battery offence to compiler or only to human race whatever python backend doesn't know the greatness of real program language
Note: I started to learn cpp for unreal engine 5
and now unreal engine 6 will be ai slop with new useless "safe" language vers in this case does it looks similar to rust
Seriously zig rust possibly java okay even java knows it's bad it used for virtual machine versatility , ease of use
..
I am shiting you for universities and for Minecraft mods that's all
All of those languages tries to be better c or cpp but we still code in c and cpp
This why we need features to existing languages
From least controversial to most
0.1 delete lua I tried to make mods on it this NOT better python and I will not stand this lil timmi propaganda
1. Add saf++ library so idea is to make this library collection of safe analogies to unsafe instructions etc
2. Make "elegant" template errors readable without llm yes I have skill issue yes I am python dev at least I am not bibe coder I use ai to learn because I am not 10x guy I started learning python in 2020\~2021 so I am new to coding even newer to cpp 2026 I don't have reputation to vibe code I am not worthy of it and maybe you too
3 cpp needs debloat now because we can't focus on what important if we have to much to review we don't need 3 if I remember correctly copys of copys we don't need lua.. we don't need to have 5 different instructions to do one thing
One thing if you think I am wrong go programe python true I am bad at programing and I am new but two is important I will try to improve not only as a programer as a person and please if somebody didn't create compiler from cpp to lua I will do it myself on cpp

I really reconsider my life choices when I have to deal tooling bugs.
I like writing useful stuff, I'm tired of fighting tooling, I can legit say %80 percent of my time goes to dealing with dependencies build systems etc. Very rarely I have the privilege of actually writing stuff.
This shit sucks, like it really sucks. I hate it.
Is this normal, or only people who have it easy are web Devs and Java Devs since they are in a sandboxes environment and don't have deployment problems.
Am I crazy or is this common?
