Receiving end does not exist.. There was some type of behavior change that happened post Chrome 72 that affected the way channels are opened.

Run Android Apps in Chrome Browser
Let’s take a look at how you can run android apps in Chrome browser. Keep in mind, this is more of a proof of concept than something you should heavily rely on. While simple apps and games will work, you will most likely run into issues when trying android apps with advanced graphics. To run android apps in Chrome browser we are going to use a modified version of the android-chrome runtime found inside of chrome.
What's bad about coding? You can work for hours with nothing to show for it
Last Saturday, I spent several hours working on my website’s code. I added some new meta tags to lazy load images, tried to remove JQuery dependencies from my scripts, added enhancements for accessibility and structured data, and even created a pull request for the theme that I am using (Beautiful Hugo).
Basically, five hours of my day were eaten up by completing those tasks. Although this was another example of getting too absorbed in your side projects, I was actually proud of myself.
I Can't Do Anything for Fun Anymore; Every Hobby Is an Attempt to Make Money
When I was a kid, it was easy to merrily invest myself in any activity that I found interesting. Building robots, learning to play guitar, and making short films were things that I would work on after school everyday. I did all those things simply because I enjoyed doing them.
Now, as a young adult, I feel like I completely lost that spontaneity and simple mindset. Every project which I take up has become an attempt to make money.
Kafka Nodejs Example with Producers and Consumers
Let’s take a look at a Kafka Nodejs example with Producers and Consumers. We will be creating a kafka producer and consumer in Nodejs. If you haven’t already, check out my previous tutorial on how to setup Kafka in docker. I already created a topic called cat that I will be using.

Prerequisites Linux System Git Docker Docker-compose Kafka and Zookeeper Start by cloning the repo:
git clone https://github.com/wurstmeister/kafka-docker Then change to the kafka-docker directory:
cd kafka-docker Now let’s edit the docker-compose.yml file. Change the Kafka Advertised Hostname to localhost:
The other day I came across a neat drone called the DJI Tello. It is a relatively inexpensive quadcopter that offers a simple SDK which can be accessed over WiFI. Using the NodeJS dgram library, I can send commands via UDP to the drone to perform actions such as takeoff, left 20, and land.
Success from Things You Don't Care About
I had just finished a YouTube that I spent a week working on; a couple of days working on the graphics, a day of voice recording, and a few more hours coming up with a nice thumbnail. I uploaded it, and eagerly awaited the YouTube algorithm to award my quality work with a burst of views and watch time. I sat and waited in anticipation. Hour one went by, nothing. Okay, maybe it’s just a little slow today.
Google's Monthly Keyword Search Volume Doesn't Matter
I spent the last month focusing a lot on seo (Search Engine optimization). One of the biggest mistakes that I made was using Google’s monthly keyword search volume as an indicator on whether a particular keyword has sufficient search volume to pursue. Google’s monthly keyword search volume is completely wrong. I found large discrepancies when comparing my actual data from Google analytics to what Google says the traffic should be.
