xrdp
An open source RDP server
xrdp provides a graphical login to remote machines using RDP (Microsoft Remote Desktop Protocol). xrdp accepts connections from a variety of RDP clients: FreeRDP, rdesktop, NeutrinoRDP and Microsoft Remote Desktop Client (for Windows, macOS, iOS and Android). As Windows-to-Windows Remote Desktop can, xrdp supports not only graphics remoting but also two-way clipboard transfer (text, bitmap, file), audio redirection, drive redirection (mount local client drives on a remote machine). Connect to a Linux desktop using RDP from anywhere (requires xorgxrdp Xorg module). Reconnect to an existing session. Session resizing (both on-connect and on-the-fly). RDP/VNC proxy (connect to another RDP/VNC server via xrdp). xrdp primarily targets GNU/Linux operating system. x86 (including x86-64) and ARM processors are most mature architecture to run xrdp on. Most Linux distributions should distribute the latest release of xrdp in their repository. -

jq
Lightweight and flexible command-line JSON processor
jq is like sed for JSON data - you can use it to slice, filter, map and transform structured data with the same ease that sed, awk, grep and friends let you play with text. jq is written in portable C, and it has zero runtime dependencies. You can download a single binary, scp it to a far away machine of the same type, and expect it to work. jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you'd expect. Data in jq is represented as streams of JSON values - every jq expression runs for each value in its input stream, and can produce any number of values to its output stream. jq filters run on a stream of JSON data. The input to jq is parsed as a sequence of whitespace-separated JSON values which are passed through the provided filter one at a time. The output(s) of the filter are written to standard out, again as a sequence of whitespace-separated JSON data. -

Mozilla JPEG Encoder Project
Improved JPEG encoder
MozJPEG improves JPEG compression efficiency achieving higher visual quality and smaller file sizes at the same time. It is compatible with the JPEG standard, and the vast majority of the world's deployed JPEG decoders. MozJPEG is compatible with the libjpeg API and ABI. It is intended to be a drop-in replacement for libjpeg. MozJPEG is a strict superset of libjpeg-turbo's functionality. All MozJPEG's improvements can be disabled at run time, and in that case it behaves exactly like libjpeg-turbo. MozJPEG is meant to be used as a library in graphics programs and image processing tools. We include a demo cjpeg command-line tool, but it's not intended for serious use. We encourage authors of graphics programs to use libjpeg's C API and link with MozJPEG library instead. Progressive encoding with "jpegrescan" optimization. It can be applied to any JPEG file (with jpegtran) to losslessly reduce file size. -

MsQuic
Cross-platform, C implementation of the IETF QUIC protocol
MsQuic is a Microsoft implementation of the IETF QUIC protocol. It is cross-platform, written in C and designed to be a general-purpose QUIC library. MsQuic also has C++ API wrapper classes and exposes interop layers for both Rust and C#. QUIC has many benefits when compared to existing "TLS over TCP" scenarios. MsQuic has several features that differentiate it from other QUIC implementations. Optimized for client and server. Optimized for maximal throughput and minimal latency. Asynchronous IO. Receive side scaling (RSS) support. UDP send and receive coalescing support. All packets are encrypted and handshake is authenticated with TLS 1.3. Parallel streams of (reliable and unreliable) application data. Exchange application data in the first round trip (0-RTT). Improved congestion control and loss recovery. Survives a change in the clients IP address or port. Stateless load balancing. -
