Firecracker is an open source virtualization technology that is purpose-built for creating and managing secure, multi-tenant container and function-based services that provide serverless operational models. Firecracker runs workloads in lightweight virtual machines, called microVMs, which combine the security and isolation properties provided by hardware virtualization technology with the speed and flexibility of containers.
 
The main component of Firecracker is a virtual machine monitor (VMM) that uses the Linux Kernel Virtual Machine (KVM) to create and run microVMs. Firecracker has a minimalist design. It excludes unnecessary devices and guest-facing functionality to reduce the memory footprint and attack surface area of each microVM. This improves security, decreases the startup time, and increases hardware utilization.
 
Firecracker was developed at Amazon Web Services to accelerate the speed and efficiency of services like AWS Lambda and AWS Fargate.

Dura is a background process that watches your Git repositories and commits your uncommitted changes without impacting HEAD, the current branch, or the Git index (staged files). If you ever get into an "oh snap!" situation where you think you just lost days of work, checkout a dura branch and recover.
 
 Without dura, you use Ctrl-Z in your editor to get back to a good state. That's so 2021. Computers crash and Ctrl-Z only works on files independently. Dura snapshots changes across the entire repository as-you-go, so you can revert to "4 hours ago" instead of "hit Ctrl-Z like 40 times or whatever". Finally, some sanity.

A Rust-powered flamegraph generator with additional support for Cargo projects! It can be used to profile anything, not just Rust projects. 
 
Flamegraphs are used to visualize where time is being spent in your program. Many times per second, the threads in a program are interrupted and the current location in your code (based on the thread's instruction pointer) is recorded, along with the chain of functions that were called to get there. This is called stack sampling. These samples are then processed and stacks that share common functions are added together. Then an SVG is generated showing the call stacks that were measured, widened to the proportion of all stack samples that contained them.

Rayon is a data-parallelism library for Rust. It is extremely lightweight and makes it easy to convert a sequential computation into a parallel one. It also guarantees data-race freedom. Rayon makes it drop-dead simple to convert sequential iterators into parallel ones: usually, you just change your foo.iter() call into foo.par_iter(), and Rayon does the rest.
 
Parallel iterators take care of deciding how to divide your data into tasks; it will dynamically adapt for maximum performance. If you need more flexibility than that, Rayon also offers the join and scope functions, which let you create parallel tasks on your own. For even more control, you can create custom threadpools rather than using Rayon's default, global threadpool.

Tremor is an event processing system. It was originally designed as a replacement for software such as Logstash or Telegraf. However tremor has outgrown this singular use case by supporting more complex workflows such as aggregation, rollups, an ETL language, and a query language. 
 
Tremor has been successfully used to replace logstash as a Kafka to Elastic Search ingress. In this scenario, it reduced the required compute resources by about 80% (YMMV) when decoding, classify, and rate-limiting the traffic. A secondary but perhaps more important effect was that tremors dynamic backpressure and rate-limiting allowed the ElasticSearch system to stay healthy and current despite overwhelming amounts of logs during spikes.
