Issue with for loop and ranges
I got stuck with a weird issue using for and ranges. The summary is, with c++20 on my macos (appleClang17) this doesn't workfor (auto [x,y]: functionThatReturnsView() )
vs this actually works
auto container = functionThatReturnsView();
for (auto [x,y]: container)

Weird memory management
I came across an old legacy code managing memory at works and here I am, at 5am in the morning, trying to understand why it doesn’t completely work. Maybe some of you could have ideas…
I have an ObjectPool<T> which is responsible for allocating predefined amount of memory at program startup, and reuse this memory across program lifetime.
To do that, they wrote an RAII wrapper called « AcquiredObject<T> », which is responsible of constructors/destructors, ->, * operators, …
And then all Types used with this ObjectPool are simple objects, often derived from multiple domain-specific objects.
BUT: after computer (not program!) being up for 3 to 4 days without interruption, a « memory leak » occurs (inside ObjectPool).
This code was previously compiled with g++4, I had to go with g++11 to resolve COTS compatibility issues. I correctly implemented move constructor and move assignment operator in AcquiredObject, thinking this bug would be tied to C++ 11 being differently compiled with those 2 different compilers versions.
I have run some « endurance » tests, with 15h without problems. And sometimes, 4 days later (computer up, not program), leak arrives within 5 first minutes.
Have you ever seen such cases ?

PSA: if you use visual studio with visual assist for C++, There was a windows update to edge (or something) that somehow breaks alt+shift+s (symbol search) by a background edge process.
Hey, just wanted to drop this somewhere on the internet to hopefully help others.
On my windows machine, I use visual studio + visual assist for large C++ projects.
A core feature, symbol search, has just arbitrarily stopped working like normal, disrupting my flow.
The feature still works, but not the keybind (alt+shift+s). This was also affecting my VSCode keybinds.
The keybind would be fine for a while, then randomly stop.
I got desperate and just started task-killing processes from the task manager
Eventually I got to msedge.exe and after stopping those processes, the issue disappeared.
I didn't even have Microsoft edge open, it seems to have opened itself in the background for some reason. (maybe updating?)
I figure there might be someone else getting affected by this, so hopefully this will get indexed to help them.
As I wasted way too much time figuring this one out.

Can someone tell me HOW file paths work in C++? (VS 2019)
Hello,
Something I haven't been able to understand about C++ is how file paths work. Whenever I try to use them, they either don't detect them or don't do anything. So, can someone explain to me what I can do? I can't keep avoiding them.

like method calls do in C++ is so complicated that it's almost impossible to truly make the library opaque for us, the users, and thus the learning curve as well as the error messages seem to be... well, scary :)
The first difference is that \`some\` is single-header library and has no external dependencies, which means you can drag-and-drop it into any project without all the bells and whistles. (It has an MIT license, so the licensing part should be easy as well)
The main difference however is that it is trying to leverage as much as possible from an already existing compiler machinery, so the compiler will generate the vtable for us and we will just happily use it. It is indeed a bit more tricky than that, since we also support SBO (small buffer optimisation) so that small objects don't need allocation. How small exactly? Well, the SBO in \`some\` (and \`fsome\`, more on that later) is configurable (with an NTTP parameter), so you are the one in charge. And on sufficiently new compilers it even looks nice: some<Trait> for a default, some<Trait, {.sbo{32}, .copy=false}> for a different configuration. And hey, remember the "value semantics" bit? Well, it's also supported. As are the polymorphic views and even a bit more, but first let's recap:
the real benefit of rolling out your own vtable is obvious - it's about control. The possibilities are endless! You can inline it into the object, or... not. Oh well, you can also store the vptr not in the object that lives on the heap but directly into the polymorphic handle. So all in all, it would seem that we have a few (relatively) sensible options:
1. inline the vtable into the object (may be on the heap)
2. inline the vtable into the polymorphic object handle
3. store the vtable somewhere else and store the vptr to it in the object
4. store the vtable somewhere else and store the vptr in the handle alongside a pointer to the object.
It appears that for everything but the smallest of interfaces the second option is probably a step too far, since it will make our handle absolutely huge. Then if, say, you want to be iterating through some vector of these polymorphic things, whatever performance you'll likely get due to less jumps will diminish due to the size of the individual handle objects that will fit in the caches the worse the bigger they get.
The first option is nice but we're not getting it, sorry guys, we just ain't.
However, number 3 and 4 are quite achievable.
Now, as you might have guessed, number 3 is \`some\`. The mechanism is pretty much what usual OO-style C++ runtime polymorphism mechanism, which comes as no surprise after explicitly mentioning piggybacking on the compiler.
As for the number 4, this thing is called a "fat pointer" (remember, I'm not the one coining the terms here), and that's what's called \`fsome\` in this library.
If you are interested to learn more about the layout of \`some\` and \`fsome\`, there's a section in the README that tries to give a quick glance with a bit of terrible ASCII-graphics.
Examples? You can find the classic "Shapes" example boring after all these years, and I agree, but here it is just for comparison:
struct Shape : vx::trait {
virtual void draw(std::ostream&) const = 0;
virtual void bump() noexcept = 0;
};
template <typename T>
struct vx::impl<Shape, T> final : impl_for<Shape, T> {
using impl_for<Shape, T>::impl_for; // pull in the ctors
void draw(std::ostream& out) const override {
vx::poly {this}->draw(out);
}
unsigned sides() const noexcept override {
return vx::poly {this}->sides();
}
void bump() noexcept override {
// self.bump();
vx::poly {this}->bump();
}
};
But that's boring indeed, let's do something similar to the std::function then?
\`\`\`C++
template <typename Signature>
struct Callable;
template <typename R, typename... Args>
struct Callable<R (Args...)> : vx::trait {
R

And a godbolt example of std::function-like thingy (and more, actually)
Hey everyone! So as you've already guessed from the title, this is another runtime polymorphism library for C++.
Why do we need so many of these libraries?
Well, probably because there are quite a few problems with user experience as practice shows. None of the libraries I've looked at before seemed intuitive at the first glance, (and in the tricky cases not even after re-reading the documentation) and the usual C++ experience just doesn't translate well because most of those libraries do overly smart template metaprogramming trickery (hats off for that) to actually make it work. One of the things they do is they create their own virtual tables, which, obviously, gives them great level of control over the layout, but at the same time that and making these calls look

Is there any way to show all "Closed Permanently" address on Google Maps?
If you aren't aware, Google will actually tell you if a listed address is permanently closed, which is very useful for finding abandoned places. But I haven't found a way to actually "browse" them, they don't have a unique indicator on the map (compared to an open address) and sometimes don't even show up at all unless you specifically search for that address (the building is just blank until you do so).
Is there any way to show all of them in a selected area, either through an official method in the app/site or some kind of bot? I’ve tried using this but I couldn’t figure out how to get it to work and it seems like I need to make my own custom script for it. It would be nice if someone could recreate this or a bot of some kind just for that very reason since I don’t know too much about this and how it’s not as easy as it looks: https://github.com/deqline/UrbexFinder

Update: Early Feedback and Platform Improvements
My last post got roasted and obliterated my karma (I'm new to reddit) but persistence is the key so I'm back to post an update.
What's New:
Guest Mode \- You can now use the platform without creating an account (thanks for the feedback!)
Concise Mode \- to cater to different audiences this mode reduces amount of text to consume, less yap more tap!
Content Strategy:
I intend to review the content but right now my focus is creating comprehensive coverage of topics at a high standard, with plans to refine and perfect each section iteratively.
My Philosophy: My commitment is to improve 1% at a time until its genuinely awesome.
Coming Next: Multi-file compilation support (think Godbolt but focused on learning) - essential for teaching functions and proper program structure.
I'm actively seeking feedback to improve the learning experience! If there's a feature you wish other C++ tutorials had but don't, I'd love to hear about it - user-suggested improvements are a top priority for implementation.
Check it out if you're curious! If you're new to programming or run into any issues, feel free to reach out. Happy coding!

Advice on learning C++ to crack platform role interviews.
Hi everyone,
I’ve spent my career working in startups with a background in robotics, which has given me broad cross-functional exposure that I’ve really enjoyed. Now, I’m looking to transition into larger organizations where C++ is used to build generic backends and middleware for autonomous systems.
Although I don’t have a formal CS background, I’ve built applications on top of frameworks like ROS and NVIDIA DriveWorks. I’ve always been interested in developing frameworks like these, which is why I started applying for such roles. However, after several unsuccessful interviews, I realized that my C++ experience hasn’t been at the abstract, systems-level depth these positions require.
I’ve reached out to people in the field but haven’t received responses, so I’m turning here for guidance. I’d love to hear from professionals at NVIDIA, Nuro, Waymo, or similar companies working on backend or generic C++ code for autonomous vehicles. Specifically, I’d like advice on:
The best resources to learn the concepts these roles require
How to practice and build the right skills to succeed in interviews
Any guidance would be greatly appreciated!

Rust vs Go for backend/infra as a C++ dev in HFT
I’m working in quant + HFT right now. My current stack includes C++ for the trading engine/low-latency work and Python for ML, research, and prototyping.
At some point, I know I’ll need to set up backend services, APIs, monitoring systems, dashboards, and maybe some DevOps tools to support both my work and personal projects. There are only so many languages one can learn, and I don’t want to overdo it, so I’m considering adding just one more that complements what I already use. Right now, my options seem to be Go and Rust.
If you were in my shoes, which language would you add as a third pillar for backend/infra? Curious to hear what others have done.
