Ask HN: Who is using C++ as the main language for new project?

• tevr-asr-tool

  9 408 5.9 C

  State-of-the-art (ranked #1 Aug 2022) German Speech Recognition in 284 lines of C++. This is a 100% private 100% offline 100% free CLI tool.

  

Me, because I plan to extend to realtime processing: https://github.com/DeutscheKI/tevr-asr-tool

Also, all the performance critical stuff on my production servers is C++ with JNI or pybind wrappers.

• windmap

  1 8 3.2 C++

• InfluxDB

  www.influxdata.com sponsored

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• slint

  138 15,020 9.9 Rust

  Slint is a declarative GUI toolkit to build native user interfaces for Rust, C++, or JavaScript apps.

  

We are using c++ mainly because Qt/QML exists. I guess if a Rust gui toolkit exists that is comparable to Qt/QML (looking at you https://slint-ui.com/), then future project would have to be re-evaluated.

• litestream

  165 9,964 7.5 Go

  Streaming replication for SQLite.

Are you saying litestream is deprecated or some specific feature? I see its very active https://github.com/benbjohnson/litestream

• mainframe

  1 3 5.0 C++

  mainframe - a lightweight dataframe library for C++

Just about any project you do in Unreal is a C++ project and Unreal is used all over the place - in games but also in industrial design and architecture for demos and visualization.

I started a project (https://github.com/tedmiddleton/mainframe) last year to make a dataframe in C++ because I was running into some performance limits in Pandas. I’m not sure how useful a C++ dataframe is - but I imagine it as being an alternative to going all the way to Hadoop and spark if you’ve outgrown pandas.

• MathAnimation

  4 952 4.4 C++

  A simple C++/OpenGL application to create quick and dirty mathematically accurate animations

I'm using C++ for a minecraft clone that I've been tinkering on for the past year[0]. I also plan on using embedded lua for scripting, and I'm using RML UI for game HUDs, ImGui for development tools, and OpenGL for graphics. I use premake for my build system but plan on switching to CMake.

I'm also using it for an animation tool[1]. I've been using 3Blue1Brown's Manim (written in Python) which is amazing, but it lacks real-time editing and proper 3D blending. It also lacks audio synchronization, 3D texture support, and some more complex features that I'd like to add :)

• nsblast

  5 3 9.1 HTML

  Massively scalable authorative DNS server

I'm using C++ for most of my projects, because I like it. It's also what I do for a living. The latest new open source project I initiated is a dns server, nsblast, using rocksdb for storage. https://github.com/jgaa/nsblast

The (side) project I have put most effort into in the last year is k8deployer, a helm like utility that can deploy simple and complex applications in kubernetes with minimal effort. https://github.com/jgaa/k8deployer

In these projects I don't use other languages. C++ is the only language where I easily get into "flow".

• k8deployer

  1 2 0.0 C++

• Tasker

  8 8 6.4 C++

  A commitment tracker desktop app that tracks the progress of your tasks with mouse, keyboard and audio hooks. (by thebigG)

I almost exclusively use C++ for my projects. Especially modern C++. When it makes sense(especially for dev tools), I use Python since for those I'm not so worried about distribution and long-term robustness.

Anyway here they are:

Qt desktop app written in C++:https://github.com/thebigG/Tasker

Simple GPIO front-end for linux GPIO driver(could definitely use some improvement) written in C++ and uses boost:https://github.com/thebigG/simple_gpio

WebApp I JUST started working on(This will be a frontend for a YOCTO/FPGA project I'm working on; guitar pedals), and yes it uses good old C++ and runs on the browser:

https://github.com/thebigG/wPedals

And while I'm at it, might as well mention my custom plugins for Godot Game Engine(C++):https://github.com/thebigG/godot-3.x-modules

I have found that C++ is the best compromise for me between performance and elegance ifI do say so myself.

we use it for redpanda https://github.com/redpanda-data/redpanda - other langs are go for k8s integration, python (dev prod tooling), ... js for ui that's mostly it.

• Rustlings

  289 49,167 9.3 Rust

  :crab: Small exercises to get you used to reading and writing Rust code!

  

I am a developer who has never worked on C++ but want to get into it full time, I did C in college, Java for the first few years in my career then Python and now exclusively Go.

When I pick up new languages and I did that for a bit with Rust, I read a bit then code a bit and found https://github.com/rust-lang/rustlings very helpful. Is there an equivalent for C++? What would be the top resource to get started on modern C++? Thanks in advance.

• uitk

  2 7 5.5 C++

  Cross-platform UI toolkit

I've been writing a cross-platform UI toolkit, currently macOS, Windows, and Linux. Eventually I'd like to compile for wasm/Canvas, android, and iOS. C++ was sort of designed for this kind of thing, it is performant, and it interfaces with the OS well. Eventually I'd like to have at least Python, Swift, and Rust bindings, because I really like using Swift, but none of the UI parts are available outside macOS.

It's probably not ready for use yet, but give it six months or so: https://github.com/eightbrains/uitk

  Program the ESP32 with Nim! Wrappers around ESP-IDF API's.

You should checkout Nim! I use it extensively on embedded. Nim is fantastic to program in if you're an experienced C/C++ developer. Its safer and smarter but not not pedantic about it.

Nim compiles to C or C++ so its easy to use on any embedded platform and compiler suite. Thats still huge for embedded. Rust forces a type-trait centric programming style which makes interfacing hardware/embedded harder as you have to make type heavy HALs everywhere -- hence the lack of rtos & library support despite its relative popularity).

Its pretty trivial to re-use any C/C++ libraries which gives a big boost to the native ecosystem. I wrapped most of the esp32 idf in a few weeks: https://github.com/elcritch/nesper

The new GC (ARC) is basically a built in `shared_ptr` or `Rc`. You can also do stack-based programming too and the compiler enforces a safe memory accesses. The performance is great and can match or beat C/C++ if you do a few hours of tuning. Though its easy kill performance if you're lazy (e.g. parse json into a bunch of heaps objects), but that can have its place.
