  • GitHub repo libcurl

    A command line tool and library for transferring data with URL syntax, supporting DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT, POP3, POP3S, RTMP, RTMPS, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET and TFTP. libcurl offers a myriad of powerful features

    Project mention: Running a GraphQL API in .NET 6 on AWS Lambda | dev.to | 2022-01-12

    Verify using curl: curl "http://localhost:/graphql?query=%7B+sysInfo+%7D"

  • GitHub repo libuv

    Cross-platform asynchronous I/O

    Project mention: Non blocking write to a file | reddit.com/r/C_Programming | 2022-01-03

    If you want real non-blocking IO, the C standard library doesn't support this and the OS-specific APIs tend to be difficult to use (and non-portable), so I would recommend something like libuv.

  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

  • GitHub repo KCP

    :zap: KCP - A Fast and Reliable ARQ Protocol

    Project mention: How feasible is this idea? Creating a battery run audio transmitter and receiver over TCP/IP | reddit.com/r/esp8266 | 2021-05-30

    I'd consider KCP protocol over TCP, it has 30-40% lower latency at the expense of 20% higher bandwidth.

  • GitHub repo libevent

    Event notification library

    Project mention: Looking for low footprint c++ library to build a REST client | reddit.com/r/cpp | 2021-12-23
  • GitHub repo Mongoose

    Embedded Web Server (by cesanta)

    Project mention: esp32 websockets sessions | reddit.com/r/esp32 | 2022-01-03

    Another option is to use Mongoose. I've got some personal gripes with it but that aside it's a great library. I've implemented a few different WebSocket interfaces with it.

  • GitHub repo cjdns

    An encrypted IPv6 network using public-key cryptography for address allocation and a distributed hash table for routing.

    Project mention: Remote code execution in cdnjs of Cloudflare | news.ycombinator.com | 2021-07-16

    I was really excited for a moment, because I thought this was cjdns https://github.com/cjdelisle/cjdns.

  • GitHub repo libwebsockets

    canonical libwebsockets.org networking library

    Project mention: Hacker News top posts: Sep 7, 2021 | reddit.com/r/hackerdigest | 2021-09-07

  • GitHub repo cute_headers

    Collection of cross-platform one-file C/C++ libraries with no dependencies, primarily used for games

    Project mention: How does a Game Engine work? An Overview | news.ycombinator.com | 2021-11-06

    The verdict for indie developers (not using Unity/Unreal) seems: just bite the bullet and buy FMOD (or Wwise or any of the popular proprietary audio engies).

    I was actually searching for a good open-source audio library to use, and found out that my options aren't that good. SoLoud is a pain in the ass to install and integrate into an existing codebase, and OpenAL doesn't have any good implementations available (either proprietary or LGPL). I'm now just using a simple single-header audio library in cute_headers (https://github.com/RandyGaul/cute_headers/blob/master/cute_s...), but will probably switch to MiniAudio once the high-level API is finished (https://github.com/mackron/miniaudio/issues/196)

  • GitHub repo netcode.io

    A protocol for secure client/server connections over UDP

    Project mention: Why is client FPS limited by netcode? | reddit.com/r/starcitizen | 2022-01-10

    You may not be there yet with your developer skills but if you are curious you can have a look at the netcode source code. I'm not sure if they're still using it since the switch to Lumberyard and Amazon Services but it's a really good and strong codebase: https://github.com/networkprotocol/netcode

  • GitHub repo miniupnp

    UPnP IGD implementation

    Project mention: pfSense CE 2.5.2-RELEASE Now Available | reddit.com/r/PFSENSE | 2021-07-14

    https://github.com/miniupnp/miniupnp/issues/413 is closed. So I’m not sure if the problem exists there still or where?

  • GitHub repo shadow

    Shadow is a discrete-event network simulator that directly executes real application code, enabling you to simulate distributed systems with thousands of network-connected processes in realistic and scalable private network experiments using your laptop, desktop, or server running Linux. (by shadow)

    Project mention: Shadow Simlulator – run real applications over a simulated Internet topology | news.ycombinator.com | 2021-04-19

    For anyone interested in following current development on Shadow, we've been publishing a series of updates. Most recent: https://github.com/shadow/shadow/discussions/1274

    The previous update has links back to the whole series; I stopped including it in the most-recent update since it was getting a bit cumbersome: https://github.com/shadow/shadow/discussions/1060
