Rigs of Rods is an open source vehicle simulator licensed under the GNU General Public License version 3. What makes Rigs of Rods different to most simulators is its unique soft-body physics: vehicles, machines, objects, etc. are simulated in real-time as flexible soft-body objects, giving the simulation an extremely accurate behavior which entirely depends on the physical construction of the vehicles or objects you create. The community contributes greatly to the game, giving it a vast selection of vehicles and terrains from which you can choose.

Sysdig is open source, system-level exploration: capture system state and activity from a running Linux instance, then save, filter and analyze. Think of it as strace + tcpdump + lsof + awesome sauce.
With a little Lua cherry on top.
The BFG is a simpler, faster alternative to git-filter-branch for cleansing bad data out of your Git repository history:

Hyperfox is a security tool for proxying and recording HTTP and HTTPs communications on a LAN.
Hyperfox is capable of forging SSL certificates on the fly using a root CA certificate and its corresponding key (both provided by the user). If the target machine recognizes the root CA as trusted, then HTTPs traffic can be succesfully intercepted and recorded.
Serf is a tool for cluster membership, failure detection, and orchestration that is decentralized, fault-tolerant and highly available. Serf runs on every major platform: Linux, Mac OS X, and Windows. It is extremely lightweight: it uses 5 to 10 MB of resident memory and primarily communicates using infrequent UDP messages.
PostCSS is a tool for transforming CSS with JS plugins. The growing ecosystem of PostCSS plugins can add vendor prefixes, support variables and mixins, transpile future CSS syntax, inline images, and more.
PostCSS is used by Google, Twitter, Alibaba, and Shopify. Its most popular plugin, Autoprefixer, is one of the most universally praised CSS processors available.
PostCSS can do the same work as preprocessors like Sass, Less, and Stylus. But PostCSS is modular, 4-40x faster, and much more powerful.
mpv is a fork of mplayer2 and MPlayer. It shares some features with the former projects while introducing many more.
The hub subcommand for git, allows you to perform many of the operations made available by GitHub's v3 REST API, from the git commandline command.
You can fork, create, delete and modify repositories. You can get information about users, repositories and issues. You can star, watch and follow things, and find out who else is doing the same. The API is quite extensive. With this command you can do many of your day to day GitHub actions without needing a web browser.
Having gone through all the pain of polishing an OpenStack installation, I can see why it might seem like a better idea to grab a couple of beers in a local bar than spend additional hours fighting Nagios or Cacti. In the world of bare metal these tools seem to do the job—they warn about abnormal activities and provide insight into trend graphs.
With the advent of the cloud, however, proper monitoring has started getting out of hand for many IT teams. On top of the relatively predictable hardware, a complicated pile of software called “cloud middleware” has been dropped in our laps. Huge numbers of virtual resources (VMs, networks, storage) are coming and going at a rapid pace, causing unpredictable workload peaks.
Proper methods of dealing with this mess are in their infancy – and could even be worth launching a startup company around. This post is an attempt to shed some light on the various aspects of cloud monitoring, from the hardware to the user’s cloud ecosystem.
