Node-Red 1.0 Released

30 Sep, 2019

Node-Red 1.0 released today. Some new features: Asynchronous message passing This release changes the message passing between nodes to be always asynchronous rather than it being sometimes asynchronous and sometimes synchronous depending on the implementation of individual nodes. Node Send API Nodes now have a new API available for how they handle messages in the runtime. This API allows them to tell the runtime when they have finished with a message. This will help the runtime to track nodes as they flow through the system - enabling future features such as automatic timeouts of nodes. To go along with this change, we’ve introduced a new Complete node. This node can be targeted at

Learn Python for free

The course isn't quite for total beginners as it assumes people have done a little programming in JavaScript or played around with the MIT-developed Scratch visual programming language aimed at kids. But it could help beginners kick-start ambitions to build machine-learning apps, web applications, or automate processes on a desktop. https://www.youtube.com/playlist?list=PLlrxD0HtieHhS8VzuMCfQD4uJ9yne1mE6

Node-Red application does not start on IBM Cloud - Never change the App Name!

04 Sep, 2019

One of my apps does not start after a restart. I changed several things on the Node-Red app and i think the restart will be a good idea. On the logs view there was no good messages to see what is happening with Node-Red So i start the terminal and go to use IBM cloud CLI to get the app log just logon and type ibmcloud cf logs \appname\ > log.txt I saw the following messages \CELL/0\ OUT Cell a64da35a-93fb-4f76-abd8-219869380b84 creating container for instance 6b30e79e-2853-4199-4c3e-1cc0 2019-09-04T13:54:47.36-0300 \CELL/0\ OUT Cell a64da35a-93fb-4f76-abd8-219869380b84 successfully created container for instance 6b30e79e-2853-4199-4c3e-1cc0 2019-09-04T13:54:55.45-0300 \CELL/0\ OUT Start

Good Technology Does the Job

31 Aug, 2019

I'm working on projects that involve many technologies and frameworks. Particularly in one of our projects the IceGuard(http://www.iceguard.com.br) many things have been used such as Flutter for mobile application, Node-Red for integrations, IBM Cloud and IBM Watson IoT services. We have reached a point where an asset management application such as sensors and gateways is required. The application has the requirements: 1 - Run OffLine and Web 2 - Data replication 3 - Authentication and Data security 4 - Integration with other applications. 5 - Implement a simple flow of approval. Another detail is that we needed it to be developed rapidly. Much is said that the Lotus IBM HCL Not

IBM Watson IoT Rules

15 Jul, 2019

Rules are key elements for an IoT solution. Using rules you can trigger an action or send an alert any kind of notification. IBM update his platform and now you can create rules using a graphical interface. The key part of a rule is the expression that will be evaluate to true or false. The expression language are built using JSONata. JSONata is a lightweight query and transformation language for JSON data. The point is that IBM are using JSONata v1.4x. and the current version of JSONata is v1.6.5. The versions have lots of difference. Yesterday i was writing a rule to get the hour for an event.

This month i am creating a Course about AI & IoT (AI & IoT Fundamentals). The course are about AI and IoT in general but i will use IBM Watson APIs, IBM Watson IoT and off course Node-Red and Raspberry Pi to make the excersices. The course is 15 hours long (lots off video) plus the exercises. Using the Keynote to generate de videos is fine but when i export the video the only option is M4V type. To convert the videos i am usin FFmpeg. 1 - Install FFmpeg brew install ffmpeg 2 - Convert to mp4 using ffmpeg -i input.m4v out.mp4 3 - Convert to webm ffmpeg -i input.m4v output.webm

Node-RED 1.0.0-beta.2 released

25 May, 2019

This is the first public beta release of Node-RED 1.0. The changes in this release are mostly focused on the editor - and there are some significant changes in there. More info here(https://discourse.nodered.org/t/node-red-1-0-0-beta-2-released/11504) Installing the beta If you want to try out the beta, you will need specify node-red@next when you use npm to update. Without the @next you'll still get 0.20.x. So on a Pi you'd do: hljs coffeescript sudo npm install -g --unsafe-perm node-red@next
