I was a bit surprised to see that you cannot reference a javascript function using a Vanilla sandbox using codesandbox.io site. Upon googling a bit here is what I found:   https://github.com/codesandbox/codesandbox-client/issues/1502   Here is the working sandbox where we can call a javascript function from an HTML file. https://codesandbox.io/s/sleepy-sunset-w0wds?file=/src/index.js Here is the explanation provided by the codesandbox.io folks on it: k, so the explanation is that in the vanilla template / parcel environment we're doing module bundling, handling src/index.js as a module. Because modules are evaluated in their own (private) scope, if you want to access from html something inside the module, you can put it on the browser's global scope, which is window. Alternatively, you can use the static template / environment, where we don't do any bundling, like https://codesandbox.io/s/quirky-flower-rm20y (but then you lose the ability to require / import).

 If you happen to buy or get your hands on the Apple Macbook Pro M1 or Macbook Air M1 based on the Apple M1 silicon chip there are a few things that might be helpful if you need to connect to your corporate VPN network using Pulse Secure application. In my case, I did have my initial doubts if the pulse secure app will work successfully or not. My doubt turned out to be true and it did not work correctly out of the box. If you download the Intel-based Pulse Secure version 9.1.9  application from Pulse secure website or from your company website, the application will not be able to successfully connect to your corporate network. It will time out with a network error!! Googled out a bit & to my luck found this community post from Pulse Secure community website  https://community.pulsesecure.net/t5/Pulse-Connect-Secure/PSAL-failed-to-Launch-Java-Applet-MacOS-Catalina-10-15-4/m-p/45177/highlight/true#M28690   It turned out that you will need to install Oracle Java 25 from here  https:/

My idea of watching movies has always been on a big gigantic screen ever since my childhood. I cherish the 3d movies watched on the silver screen theatres starting right from the vintage Chota Chetan till the recent Avengers End Game!  My setup details With the pandemic striking in 2020 it has become a distant dream to watch these 3d movies again in theatres. Thankfully I have my Benq 3D projector MX525 to the rescue. My Benq 3D projector MX525 (Cost around Rs 30K) in combination with my Sony 3D Blu-ray home theatre BDV-E3200 (Cost 30K) creates the magic of the large theatre-like vision and the high fidelity sound output. The magic of the 3D is witnessed through the DLP 3D glasses from Hi-Shock/IT-Hub India(Cost Rs 2500 per pair). The 5x5 ft projector screen that I am using is from a company called Logic which cost me around 4K bought from SP road in Bangalore. The overall cost of the setup is about Rs 72,000/-  A word about Avatar The movie which brought 3D to the forefront is none ot
