LibreSSL 4.1.0 released Apr 30th, 2025 LibreSSL is a version of the TLS/crypto stack forked from OpenSSL in 2014, with goals of modernizing the codebase, improving security, and applying best practice development processes. Primary development occurs inside the OpenBSD source tree with the usual care the project is known for. On a regular basis the code is re-packaged for portable use by other ope
What is curl used for? curl is used in command lines or scripts to transfer data. curl is also libcurl, used in cars, television sets, routers, printers, audio equipment, mobile phones, tablets, medical devices, settop boxes, computer games, media players and is the Internet transfer engine for countless software applications in over twenty billion installations. curl is used daily by virtually ev
tunemu Tun device emulation for Darwin tunemu allows programs that require tun devices to run on Darwin (OS X) without kernel support. How tunemu uses the kernel ppp driver to create a ppp device. It then reads packets from the ppp instance and writes packets to the loopback device using libpcap. Source tunemu.h tunemu.c tunemu is part of Hans. Supported programs Hans In order to build Hans with t
Give employees, partners and customers a central place to access training programs on any device. Bridge is an all-in-one learning management system and skills platform that can help with employee development, manager enablement and corporate training. Whether you need to fast-track new hire onboarding, launch leadership initiatives, train customers or pinpoint skill gaps (and create epic plans to
Introduction The structure of this tutorial assumes an intermediate level knowledge of Python but not much else. No knowledge of concurrency is expected. The goal is to give you the tools you need to get going with gevent, help you tame your existing concurrency problems and start writing asynchronous applications today. Contributors In chronological order of contribution: Stephen Diehl Jérémy Bet
Hi. The RSCODE project is an implementation of a Reed-Solomon error correction algorithm. Error correcting codes are marvelous jewels of mathematics and algorithms, providing an almost supernatural ability to recover good data from a corrupted channel. This implementation of the Reed-Solomon codes provide convenient 'byte-sized' block coding which is convenient for adding protection to data which
I am sure many programmers writing network applications have their own abstracting layers hiding the differences between various I/O multiplex APIs, like select(2), poll(2), epoll(2), ... And of course, I am one among them. While writing mycached (see Mycached: memcached protocol support for MySQL for more information), I was at first considering of using libev for multiplexing socket I/Os. Libe
分散KVS kumofs のコードは、全体で約2万行です*1。 そのうち、ネットワークI/Oやプロトコルに関するコードは約1万行*2で、全体の約半分を占めています。 ロジックは残りの半分*3だけで実装されています。 この実例から分かりますが、kumofsのような分散アプリケーションを開発するにはI/O周りの実装が大変で、とてつもなく大きな障壁になっています。*4 さらに今日では、性能を稼ぐためにマルチスレッド化が必須です。また、多数のクライアントを少ないリソースで効率よく相手にするには、非同期・イベント駆動型のアーキテクチャも必要になります。さらに、究極的な性能を達成すべく GC を利用しない C++ においては、実装のみならず設計も大変です。 これに加えてソケットAPIの難解な挙動に対処にしなければならないため、C言語やC++によるネットワークプログラミングは、vimの使いこなしなどと同
