In this article I’m going to show you how to install a Node-RED Server that includes optional advanced capabilities, that are not available by default with the standard installs mentioned in Node-RED’s documentation.

If you’re following my Up and Running with Node-RED series, you’ll know that my intention is to teach you how to use Node-RED as a tool for business app development and integration, instead of just home automation and hobby-based projects. To achieve this, we cannot set up Node-RED the traditional way, which is installing it as a global module on our local machine. We need more control and flexibility. For example:

  • To run multiple instances of Node-RED
  • To containerize and deploy to various on-prem and cloud environments
  • To integrate with 3rd party services

Everything needs to be achievable from one Node-RED instance, and today’s install will give us just that.

Node JS and NPM Required

To start, you need to have at least Node JS 12.18 or higher installed on your machine. If you have an older version or don’t have Node installed, I highly recommend using a Node Version Manager to be able to install one or multiple versions of Node. There are many great Version Managers out there, but for an immediate recommendation, NVM is one that we at Agilit-e use and it works very well. Not only will you be able to easily switch between various versions of Node, but NVM also takes care of permission issues on your Operating System that sometimes occurs when installing Node directly.

Find “agilite-node-red” on GitHub

Now, the boilerplate Node-RED server we’re going to be using can be found on GitHub and is called agilite-node-red. This repo is maintained by the team at Agilit-e and provides the control and flexibility mentioned earlier.

Download Relevant Version

Once the boilerplate repo is open in your browser, switch the branch from Master to 7.3.1. This is the current boilerplate version as per the release of this article, is compatible with Node 12.18, and runs Node-RED 1.3.4. Should you be reading this article long after it was released, you can switch to newer branches that will support upgraded versions of Node and Node-RED. Reference the README file for these versions.

Once you’ve switched to branch 7.3.1, click on the Code button, following by clicking on download zip to download the boilerplate to your local environment. One downloaded, extract the zip file, which will extract the boilerplate to a folder called agilite-node-red-7.3.1.

Install Node Modules

Via your Terminal or Command Prompt, navigate to the boilerplate folder and run the following command 

npm ci — only=production

. This installs the main project dependencies based on the package-lock.json file and ignores the dev dependencies which you don’t need. This ensures the boilerplate’s node modules are installed the way we intended, to avoid possible inconsistencies and problems.

Once the NPM install is complete, enter the command 

npm run main

. This starts up the Node-RED server, which you can now access by opening your preferred web browser and entering the URL: http://localhost:6020. If all was successful, you will see the Node-RED Editor open in your browser’s window. You are now ready to start using Node-RED.

Closing

As mentioned before, this boilerplate offers everything of Node-RED and more, which I’ll be taking everyone through step by step in my Up and Running with Node-RED series. So if you haven’t yet, be sure to subscribe to my YouTube channel, or alternatively follow me on this site. In the meantime though, I welcome you to peruse the configuration for this boilerplate, which can be found in the config/templates folder, in a file called default-config.json. This is where much of the magic happens, but more on that very soon.

Until next time though…cheers 🙂

Samsung hopes to ‘copy and paste’ the brain to 3D chip networks

Published

on

Samsung thinks it has a better way to develop brain-like chips: borrow existing brain structures. The tech firm has proposed a method that would “copy and paste” a brain’s neuron wiring map to 3D neuromorphic chips. The approach would rely on a nanoelectrode array that enters a large volumes of neurons to record both where the neurons connect and the strength of those connections. You could copy that data and ‘paste’ it to a 3D network of solid-state memory, whether it’s off-the-shelf flash storage or cutting-edge memory like resistive RAM.

Each memory unit would have a conductance that reflects the strength of each neuron connection in the map. The result would be an effective return to “reverse engineering the brain” like scientists originally wanted, Samsung said.

The move could serve as a ‘shortcut’ to artificial intelligence systems that behave like real brains, including the flexibility to learn new concepts and adapt to changing conditions. You might even see fully autonomous machines with true cognition, according to the researchers.

There’s a glaring problem with complexity, however. As a human brain has roughly 100 billion neurons with a thousand times more synaptic links, an ideal neuromorphic chip would need about 100 trillion memory units. That’s clearly a difficult challenge for any company, and that doesn’t include the code needed to make this virtual brain work. Samsung may have opened a door to human-like AI, but it could take a long time before anyone reaches that goal.

Apple will fix bug preventing iPhone 13 owners from unlocking with Apple Watch

Published

on

Are you unable to unlock your brand new iPhone 13 with your Apple Watch? Don’t despair just yet. According to MacRumors, Apple has promised to fix a bug that prevents the unlock through an “upcoming software update.” You can turn off the feature in Settings and rely on passcodes until that solution is in place, Apple said, although it didn’t offer a timeframe for the patch.

The flaw typically tells users the iPhone is “unable to communicate” with the Apple Watch. Others can’t setup the unlock feature in the first place. As you might imagine, that’s a significant hassle if you’re wearing a face mask and can’t use Face ID to sign in.

You might not have to wait too long. While Apple only recently started testing an iOS 15.1 beta, the company has a long history of delivering small-but-quick updates that fix glaring bugs and security holes. While this certainly isn’t how Apple wanted the iPhone 13 launch to go, the issue isn’t likely to last.

Tesla drivers can now request Full Self Driving beta tests

Published

on

It took a long while, but Tesla is finally giving you some control over when (and if) you get Full Self Driving beta releases. The Washington Post noted that Tesla has begun rolling out an FSD beta request button that lets you try the autonomous (really, semi-autonomous) technology before its wider release. The automaker won’t just hand test code to anyone, though. Elon Musk noted that Tesla will “assess driving behavior” (like hard braking, aggressive turns or tailgating) for a week to reduce the chances of collisions.

The move could boost uptake for Full Self Driving betas and help Tesla refine the system for wider releases. The just-launched FSD 10.1 beta (mainly a bug fix) arrived too soon for that, but future software could be more polished or reach a general audience sooner.

Not everyone is thrilled with Tesla’s rapid Full Self Driving expansion, however. The National Transportation Safety Board’s new leader, Jennifer Homendy, recently joined other critics in accusing Tesla of “irresponsible” marketing for FSD technology that could lead to dangerous misuse. She also claimed Tesla was unresponsive to official recommendations for improvements. Beta requests may help Tesla achieve its goals sooner than before, but they won’t address broader concerns about FSD’s safety and whether or not customers should be testing semi-autonomous features on public roads.

Docker Images: Name Vs. Tag Vs. Digest

Published

on

A docker image usually has 3 parts: name, tag, and digest. Images can be pulled using name, or name:tag or [email protected]:digest. Some images are multi-architecture images. In such cases, docker automatically pulls the appropriate image for the os/arch the pull command is run on. Use docker manifest inspect –verbose to view os/arch’s of an image and to get the digest. Avoid using the latest tag in a product environment since it makes rollbacks hard.
