Features

  • Statistical analysis across multiple runs.
  • Support for arbitrary shell commands.
  • Constant feedback about the benchmark progress and current estimates.
  • Warmup runs can be executed before the actual benchmark.
  • Cache-clearing commands can be set up before each timing run.
  • Statistical outlier detection to detect interference from other programs and caching effects.
  • Export results to various formats: CSV, JSON, Markdown, AsciiDoc.
  • Parameterized benchmarks (e.g. vary the number of threads).

FAI – Fully Automatic Installation

FAI – Fully Automatic Installation

FAI is a tool for unattended mass deployment of Linux. It’s a system to install and configure Linux systems and software packages on computers as well as virtual machines, from small labs to large-scale infrastructures like clusters and virtual environments. You can take one or more virgin PC’s, turn on the power, and after a few minutes, the systems are installed, and completely configured to your exact needs, without any interaction necessary.

Sequence diagrams

I neede to draw some sequence diagrams. Many people use presentation software like LibreOffice Impress or drawing software but I’m lazy and slow with those programs. Let’s add that I want to use them in a reveal.js presentation. So I asked DuckDuckGo, discovering https://github.com/denniskniep/reveal.js-plugin-sequence-diagrams which uses https://bramp.github.io/js-sequence-diagrams/. The latter in particular is really a smart piece of software!

Nanos.org

 Nanos.org: Run code faster than the speed of light

A unikernel running one and only one application in a virtualized environment. More secure and faster than Linux. All while keeping it simple.

Of course it runs faster than Linux. No fork, one process and several other significative simplications.

 

Apache NuttX

Apache NuttX

Apache NuttX is a mature, real-time embedded operating system (RTOS).

 

Apache NuttX

NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 32-bit microcontroller environments, the primary governing standards in NuttX are Posix and ANSI standards. Additional standard APIs from Unix and other common RTOS’s (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
