- The Important Features and Fixes of Node.js Version 8 | @RisingStack
- In this post, we go through the most important features and fixes of the new Node.js version 8, which becomes the current LTS release from October.
- async hooks, node.js version, different Node.js versions, V8 team,
- Control a HackRF device (e.g. Jawbreaker, HackRF One, or Rad1o) from node – – This is a low-level binding to .
- Returns an array containing information about the connected HackRF devices.
- If no devices are connected, an empty array will be returned.
- Opens and returns the device in the array of devices with index .
- should be an integer – – Set the lna gain.
- Prepare the imagedataBefore we can train the recognizers we have to collect some image data with faces.
- As I simply picked some images from the web, we have to extract a subimage centered at the face of the character shown in each image.
- We will read the images and split them into a set of training and test samples as follows: – This will give us the following face images: – Resizing the images is necessary, as the recognizers expect the data to be equally sized images.
- We can now run the prediction of our test images: – Running the example should give us the following output: – eigen: – predicted daryl to be: daryl, confidence: 1245.68 – predicted negan to be: negan, confidence: 2247.25 – predicted rick to be: negan, confidence: 2502.47fisher: – predicted daryl to…
- There is also a second face recognition example in the repo, which produces the result shown in the title image, just in case your interested.
- With the release of Node.js Version 8 (happening on 12 PM PST 30 May), we got the latest LTS (long-term support) variant with a bunch of new features and performance improvements.
- – Daniel Clifford and the V8 team – – Currently (well, with V8 versions older than 5.6, so anything below Node.js version 8) this is how the V8 compilation pipeline looks – – The biggest issue with this pipeline is that new language features must be implemented in different parts…
- The new Node.js 8 release also ships with npm 5 – the newest version of the npm CLI.
- Highlights of this new npm release: – – Node.js version 8 surprises us with a lot of interesting improvements, including the Async Hooks API which is hard to grasp with the current (but ever evolving) state of it’s documentation.
