Toph—A Competitive Programming Platform

http://toph.co
我用Go、MongoDB、Redis、RabbitMQ和类似s3的对象存储构建了Toph. 该平台在构建时考虑了可伸缩性和弹性. 用户提交的代码在定制的沙箱和Go中处理，使用Linux命名空间和cgroups来隔离进程并限制资源.

By May 2021, Toph already had 30,000 users, processed 700,000 submissions, and hosted 400+ programming contests, 其中大部分是由与Toph合作的50多家学术机构组织的.

Redsync — A Redis-based Distributed Lock

http://github.com/go-redsync/redsync
Redsync为Go提供了一个基于redis的分布式互斥锁实现, as described in the following post: http://redis.io/topics/distlock.

锁算法比使用单个Redis实例更安全.

Brdgd — P2P File Transfer using WebRTC

http://github.com/hjr265/brdgd
Brdgd，发音为“桥接”，是一个简单的P2P文件传输网络应用程序. It depends on PeerJS to manage the P2P connections. The web app, in rare cases, 当对等体由于某些明显的原因无法相互到达时，使用轮流服务器来中继连接.

Scanlib

http://github.com/FurqanSoftware/scanlib
Scanlib是一个元解析器，可用于验证文本文件. Scanlib is also able to emit C++, Go, 以及可以将类似结构的文本文件的内容读入变量的Python代码.

在为竞争性编程竞赛设计编程挑战时，这对于验证输入文件非常有用.

Arturia | Sandbox for Linux Processes

Arturia是一个用于Linux的沙盒软件和流程编排器. 它使用Linux名称空间、cgroups和seccomp BPF将资源与不受信任的进程隔离开来.

我在Toptal Engineering Blog上写过关于Linux名称空间的文章:http://laid.ngskmc-eis.net/linux/separation-anxiety-isolating-your-system-with-linux-namespaces.
