Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

MicroFlo: Live dataflow programming for microcontrollers

Build Status

Unlike most other dataflow runtimes for constrained devices, MicroFlo run standalone on the microcontroller, can be introspected and reconfigured at runtime, and has built-in support for automated testing.

One can program with MicroFlo either:

  • Visually, using Flowhub
  • Textually, using the declarative .fbp DSL or .json definition
  • Programatically, by embedding it and building a graph using the C++ API

MicroFlo is very portable, written in C++03 without exceptions and stdlib. It comes with support for multiple platforms,including Arduino and Embedded Linux. It has been used on many different devices, from Atmel AVR8 to ARM Cortex M0/M1/M3/M4 devices (LPC mbed, TI Tiva/Stellaris), ESP8266 and Raspberry PI.

MicroFlo is designed to integrate with other data-driven programming tools, including msgflo for easy building of distributed systems (IoT).

Using

For visual programming your Arduino, follow the microflo-example-arduino.

Support

Flowhub logo

MicroFlo is a part of Flowhub, a platform for building robust IoT systems and web services. We offer an Integrated Development Environment and consulting services.

Status

Minimally useful.

  • Works fine for simple programs
  • Components exists for standard I/O on Arduino devices
  • Live programming supported for most changes
  • Basic support for automated testing

MicroFlo in the wild:

  • Jon's fridge thermostat has been running uninterrupted since September 2013.
  • The Ingress table at c-base station, Berlin uses MicroFlo to control the lights. One major upgrade/bugfix since March 2014.
  • The lights on the CNC-milled Christmas tree at Bitraf, Oslo ran for 4 weeks during Christmas 2013.
