Telegram is a wonderful and private messaging app that offers simple, fast, secure and synced messaging for all your devices. It delivers messages faster than any other application; cloud-based so you can access your messages from any device; and very secure, with messages heavily encrypted and could even self-destruct. Telegram is simple and fun to use, with powerful photo and video editing tools as well as an open sticker/GIF platform to let you express yourself fully. It’s also incredibly powerful. Whether you’re setting up a group chat for up to 200,000 members or sharing large videos or documents, Telegram is up to the task. Best of all it’s completely free and open source, with no ads or subscription fees.

This is the official Android SDK for Stream Chat, a service for building chat and messaging applications. This library includes both a low-level chat SDK and a set of reusable UI components. Most users start with the UI components and fall back to the lower-level API when they want to customize things. We're proud to say that we're the first Android Chat SDK that supports Jetpack Compose! We released our Compose UI Components one day after the official Jetpack Compose 1.0 release and our team members have been working hard on it since then. Now it's mature and stable enough for us to officially recommend it for all new applications and all modern chat implementations. If you're looking for something highly customizable and extremely performant, check out our Compose SDK.

Conversations is an open source Jabber/XMPP client for Android, designed to provide a unique and more freeing mobile messaging experience. XMPP is a federated protocol that can work with every XMPP server out there, giving you the freedom to choose a trustworthy server for yourself while still being able to chat with contacts from other servers. All communications are TLS encrypted and Conversations offers to enable one of two state of the art end-to-end encryption mechanisms, so you can be assured of the highest level of security in messaging.

Signal Server is the official backend server component that supports the Signal Private Messenger ecosystem on Android, iOS, and desktop platforms, serving as the trusted message relay, contact discovery, and push notification hub while the clients handle end-to-end encryption. Built in Java and licensed under the AGPL-3.0 license, this server software handles protocols for delivering encrypted messages, synchronizing user metadata like public keys and push tokens, and providing REST and service APIs for the client apps to interact with. Although cryptographic operations and message confidentiality are managed by the client side using the Signal Protocol, the server ensures message routing, user registration, and group updates without having access to the decrypted contents. Its codebase is public to ensure transparency and auditability for a security-focused community willing to inspect how message metadata and delivery mechanisms are implemented.

LMAX aims to be the fastest trading platform in the world. Clearly, in order to achieve this we needed to do something special to achieve very low-latency and high-throughput with our Java platform. Performance testing showed that using queues to pass data between stages of the system was introducing latency, so we focused on optimising this area. The Disruptor is the result of our research and testing. We found that cache misses at the CPU-level, and locks requiring kernel arbitration are both extremely costly, so we created a framework which has "mechanical sympathy" for the hardware it’s running on, and that’s lock-free. This is not a specialist solution, it’s not designed to work only for a financial application. The Disruptor is a general-purpose mechanism for solving a difficult problem in concurrent programming. It works in a different way to more conventional approaches, so you use it a little differently than you might be used to.
