MicroFlo and IoT: measuring air quality

Fine particulate matter is a serious issue in many cities around the world. In Europe, it is estimated to cause 400.000 premature deaths per year. European Union has published standards on the matter, and warned several countries that haven’t been able to reach the safe limits.

asComponent: turn any JavaScript function into a NoFlo component

Version 1.1 of NoFlo shipped this week with a new convenient way to write components. With the noflo.asComponent helper you can turn any JavaScript function into a well-behaved NoFlo component with minimal boilerplate.

Publish your data on the BIG IoT marketplace

When building IoT systems, it is often useful to have access to data from the outside world to amend the information your sensors give you. For example, indoor temperature and energy usage measurements will be a lot more useful if there is information on the outside weather to correlate with.

Get ready for NoFlo 1.0

After six years of work, and bunch of different projects done with NoFlo, we’re finally ready for the big 1.0. The two primary pull requests for the 1.0.0 cycle landed today, and so it is time to talk about how to prepare for it.

One important aspect of any Internet of Things setup is being able to collect and visualize data for analysis. Seeing trends in sensor readings over time can be useful for identifying problems, and for coming up with new ways to use the data.

Flowhub IoT hack weekend at c-base: buttons, sensors, the Big Switch

Last weekend we held the c-base IoT hack weekend, focused on the Flowhub IoT platform. This was continuation from the workshop we organized at the Bitraf makerspace a week earlier. Same tools and technologies, but slightly different focus areas.

Two hackathons in a week: thoughts on NoFlo and MsgFlo

Last week I participated in two hackathons, events where a group of strangers would form a team for two or three days and build a product prototype. In the end all teams pitch their prototypes, and the best ones would be given some prizes.

NoFlo: six years of JavaScript dataflow

Quite a bit of time has passed since my two years of NoFlo post, and it is time to take another look at the state of the NoFlo ecosystem. To start with the basics, NoFlo is a JavaScript implementation of Flow-Based Programming:

Bosch Connected Experience: Eclipse Hono and MsgFlo

I’ve been attending the Bosch Connected Experience IoT hackathon this week at Station Berlin. Bosch brought a lot of different devices to the event, all connected to send telemetry to Eclipse Hono. To make them more discoverable, and enable rapid prototyping I decided to expose them all to Flowhub via the MsgFlo distributed FBP runtime.

As the readers of this blog know, I’ve been working on a Flow-Based Programming implementation for JavaScript in the form of the NoFlo project. The idea of FBP in nutshell is to separate the control flow of software from the actual implementation. Developers build reusable “black box” components that are then connected with each other through a graph that you...

August was a big month for NoFlo. We launched the Kickstarter campaign, which went from 0 to 90% inside the month.

There has also been quite a lot of media coverage, and I thought to collect these into one place. To...

Why did I reimplement Jekyll using NoFlo

Jekyll is a delightful piece of software. A Ruby application that turns your Markdown and HTML files to a nicely constructed static website. Since the generated site is static, you can deploy and serve it from anywhere with no security or performance concerns. As a matter of fact, this site is built with Jekyll.

Software is not text

It has been interesting to watch the reactions to Bret Victor’s The Future of Programming and our NoFlo Kickstarter. While much of it has been supportive, there seems to be a largish group of people that are offended by these notions. How dare we suggest that software could be made in other ways than textually?

NoFlo: two years of flow-based programming

NoFlo — the flow-based programming system I started — is now two years old. I pushed the first commits to GitHub on June 5th 2011 from Hacker Dojo in Mountain View. To get us started with the story, I’ll let Wikipedia summarize:

Writing reusable, multi-platform JavaScript with Component

I’m currently in the process of porting the NoFlo Flow-Based Programming environment to run also in the browser. While there are some obvious differences in things like filesystem interaction and component loading, the goal here is to reuse as much of the same code as possible between these two platforms.

Thinking about the flow-based programming user interface

As readers of this blog already know, I’ve been working on the NoFlo flow-based programming environment for JavaScript. Lately the development effort has received a large boost from both the EU-funded SmarcoS Project and client work, and so the question of a flow design UI has become even more urgent.

Distributing NoFlo components via NPM

NoFlo is an implementation of the Flow-Based Programming model for Node.js. Today I’ve released version 0.2.0 which provides a handy new feature: the ability to share components via NPM.
