YACP - yet another c project
Hi all :)
Was browsing for new project ideas, and i stumbled across this GitHub repo: [https://github.com/practical-tutorials/project-based-learning?tab=readme-ov-file#cc](https://github.com/practical-tutorials/project-based-learning?tab=readme-ov-file#cc)
From the list I have selected these:
* DB: [https://cstack.github.io/db\_tutorial/](https://cstack.github.io/db_tutorial/)
* TCP/IP: [https://www.saminiir.com/lets-code-tcp-ip-stack-1-ethernet-arp/](https://www.saminiir.com/lets-code-tcp-ip-stack-1-ethernet-arp/)
* REDIS: [https://build-your-own.org/redis/](https://build-your-own.org/redis/)
* MQTT broker: [https://codepr.github.io/posts/sol-mqtt-broker/](https://codepr.github.io/posts/sol-mqtt-broker/)
* OS: [https://github.com/tuhdo/os01](https://github.com/tuhdo/os01)
Now, I am wondering which of them should I start. The goal would be to rewrite the existing thing to C++. You may assume that they are sorted by how interesting they sound to me.
At the end i guess my question would be: which one of these is going to boos my CV the most? I would aim to be interesting to a broad recruitment audience, instead of niche like game dev.

Are there pitfalls associated with only use the C parts of C++?
Hello,
I was originally planning to learn C, but I soon realized many of the libraries I want to use are written in C++ and don't offer C wrappers. So as a compromise, I'm thinking of writing C and only using parts unique to C++ when the occasion calls for it.
I'm aware that there are a few edge cases where C code doesn't exactly translate. Other than this, I'm wondering if there are pitfalls to doing this.
If there are C++ developers who've tried / do this, would like to hear your experience with it.
Also I hear C++ has much longer compile times. Would restricting myself to the C parts of C++ help with this?
Edit: Context, I'm a developer with a few years of experience. I mostly program in Python, Rust, JS, and Java. Had some exposure to C++ from college courses, but that was long ago.

Difficulty in integrating firebase
So I am building a project in c++, in which I want to add firebase, but I am not able to do so.
Read a lot of articles but any of that didn't worked. Some say to install node.js then later install firebase. I am just building a cmd based project neither web based not android based project.
Can anyone help me in this, please. I need full guide from basic how to install firebase on linuxmint, integrating it to CMakeLists.txt and use that firebase for authentication purpose.

Making libraries for a graphics engine, how should I organize them
Hey All,
I'm not quite completely new at c++ but I am fairly new to having unguided fun with it. I'm wondering what is the best way to organize libraries so that they can be useful to other developers using my codebase. Currently I'm working on a 3D Graphics Engine that will use a matrix library, which I am breaking into a vector library and a linear algebra library. I'm wondering how I should organize the file system for these components. Currently I just have a folder for each one which stores the header and cpp files. I'm here to hear about how wrong I'm doing things so let me know. Thanks

A survey on C++ usage
Hello everybody,
we are performing a survey among companies using C++ and C++ developers in general about the trends in the usage of the language. We do realize that similar surveys exist, but we are trying to get to varying audiences and compare our results to the rest. After collecting other data through similar activities, we will compile a whitepaper to summarize the findings, and share it with the participants. If it caught your interest and you work with C++, please fill in this form, it will only take you a couple of minutes. Thank you!

Secure Auth in c++
Hey guys 😊
How is it we don't have production grade secure Auth libraries in cpp? I've recently come across this issue. I'm currently building a rest API based on Drogon and I was just beginning to write an Auth endpoint when I wondered...how am I going to handle this? Sure, jwt-cpp tokens in the header and a httpFilter class filtering traffic based on access level and Authentication by verifying the jwt, but - how do I actually authenticate my users for them to receive a jwt? I started looking and...came up empty or nigh empty. Some libraries do exist, like libsnark or libstarks for ZKP, but those are not production grade but more of an academic paper. Botan does exist, but apparently it's pretty broken (my ide keeps saying classes like Botan::SRPServerSession don't exist despite including the header files and the class being actually defined inside it, wtf. It's probably an issue with that public api macros botan uses, but I can't put a library in a ci pipeline when it needs tinkering to work). Now, there's TONS of rust libraries... In the end, I ended up implementing a challenge - response algorithm myself, but having to resort to openssl primitives for a secure authentication algorithm should not be the standard solution, and neither should be importing rust modules via FFI.

I'm trying to decide between getting the 2nd or 3rd edition of "Programming: Principles and Practice Using C++" by Bjarne Stroustrup. For those who've used either or both, are there any significant updates or changes in the 3rd edition that make it worth getting over the 2nd? Also, I noticed that the 2nd edition has more pages.

Modern C++ Mongo API
A C++ API to mongo I have been working on:
https://github.com/Loki-Astari/ThorsMongo
It is NOT a full implemenation of the Mongo C++ drivers (just the basic CRUD operations). But provides (I hope) an intuative easy to use API.
Main feature is that you don't need to know BSON. The generation of BSON an all associated structures is automated away usign some easy to use declarations. Try and use the C++ type system to validate (at compile time that you are passing in the correct values for searches and updates (still some work here)).
Would love any suggestions on next steps that would make it useful to others.

Need good resources on Qt C++
I'm a beginner/intermediate C++ student. I need resources on how to make projects and different project ideas.
My skills:
1. C++:
• OOP
• Dynamic memory management
2. Git and GitHub (Repository management)
3. Basic Qt application development
4. I know how to write Python code 😁
Jokes aside, I want to build my skills in C++ OOP and Qt application development (Windows applications).
Currently, I’m learning Qt basics from Daniel Gakwaya’s courses on Udemy and YouTube. C++ was my high school language, and I don’t get why people hate on it—I find it useful, especially since I’m interested in SBCs and microelectronics.
Looking for advice on resources and project ideas to help me develop my skills further.

The age old compiler question
... It bugs me, once again.
Which compiler has the edge right now? Mostly in terms of runtime performance. Clang 18.1.8 or gcc 14.2, I've tried them both - clang self compiled and gcc from the toolchain repo. My clang++ builds were with lunwind, flto, lld linker, libc++, o2, march=znver4, g++ builds having libstdc++ and gold linker and no libunwind. Postgres, for example, does perform similarly with both, openssl seems to be a bit faster with gcc. Is there a sort of consensus right now as to the areas where each excels?

Ultra Engine 0.9.7 Released
Hi, I have an update on the development of Ultra Engine, our game engine for C++ and Lua development.
As we approach version 1.0, the latest update adds a new decals system, which blend seamlessly with PBR materials in our clustered forward+ renderer, and work with transparency. A filtering system allows control over which decals appear on which objects.
Particles make their first appearance in 0.9.7, with controls for a variety of settings and real-time feedback in the level editor.
Entities now support individual texture offset and scaling settings, as well as a per-entity emission colors.
You can read more here if you are interested:
https://www.ultraengine.com/community/blogs/entry/2850-ultra-engine-097-released/
Ultra Engine was created to solve the problems we saw while working on virtual reality projects at NASA. We are developing game engine tools to provide order-of-magnitude faster performance for 3D and VR applications in entertainment, defense, and aerospace.
Please let me know your thoughts. Thanks for the support, and keep coding!

Embedded sw testing and documentation for small to medium sized projects
I will soon be starting a new job. While having my job interview about the current projects my new employer works on, I developed the impression that testing and documentation of the code plays only a rudimentary role. The system-testing seemed fine enough, but unit-testing and integration-testing are hardly present. In the last two years, I worked in testing of python-code of embedded systems and witnessed many times, how important thorough testing is. What frameworks/environments are recommendable for testing and documentation of small and medium sized embedded projects? It can be either open- or closed-source. Some suggestions for discussion:
* [Doxygen](https://www.doxygen.nl/): documentation
* [Cpputest](http://cpputest.github.io/): Unit test and integration test
* [Google Test](http://google.github.io/googletest/): Unit test and integration test

Fuming after Think-Cell programming test
I am extremely protective of my time in general. Today was a beautiful, sunny day, and I had other things I really wanted to do.
Instead, It wasted an entire fucking day doing this 9 hour Think-Cell programming exercise - and yes, I actually spent about that long on it. I wish I'd googled it beforehand, as I now see it's quite notorious. I feel very naive.
A few days ago a recruiter contacted me on LinkedIn with a job spec that seemed too good to be true. £110k per year (after the first year), and fully remote.
I spent my mornings before work brushing up on the latest C++ features in preparation. Then today, after a bit more studying, I started the test around 10am.
It seemed fairly difficult at first, but not overly so. After a few hours I had a solution that was correct, but apparently too slow. The feedback on the website said I should be able to do it with just a single O(log n) call to std::map. I then spent absolutely ages coming up with an alternative solution. Every time I entered the code into the web page and hit the compile button, it would refresh the page and show the results. What I didn't realise was that it was just displaying the results from my previous (too slow) submission. Eventually I gave up and hit submit and apparently this submission failed on correctness. I tried setting the _GLIBCXX_DEBUG flag on g++, and it revealed a simple mistake, which I fixed instantly, but it was too late - I don't get another chance to submit a solution. Just an automated message that they won't be inviting me for an interview. No human is even going to look at it. I'll never know if my second solution passed the performance requirement.
By contrast, the last company I did a programming exerise for actually paid me (I think about £100). It didn't take as long, and it was actually seen by a real person. I didn't get that job, sadly, though I got to the final round of interviews.
If anyone wants to do me a favour, try applying and submitting my solution and let me know if it passes. I need closure.
