It is pretty interesting to see how the pandemic is pushing people to come up with various product ideas. For whiteboards, there have been many ideas and concepts lately. I am also working on a whiteboard app but it is a different concept. Our tool is using AI to recognize the shapes that make it easy to draw otherwise you end up drawing messy shapes on screens. Here is link to our landing page: https://lekh.app

I like your tool rajeevk. Will definitely have a try!

Here is my article that explains how C code can be understood in terms of assembly: https://www.avabodh.com/cin/cin.html

I also wrote another article which explain how C++ code can be understood in terms of C code: https://www.avabodh.com/cxxin/cxx.html

The next priority in my project is to integrate payment. I decided to use Stripe. Given this, now I think I should review my decision. I am checking with HN users, what alternatives are out there and what is your experience with them.

Only a few HN posts can make it to the front page. Only if you are lucky then you will be able to raise your voice through here. So I assume there would be many users out there affected like this and their issues were never resolved.

I am the developer of https://lekh.app When I first experimented with the web assembly, it was kind of magic for me. I had a diagramming app called Lekh Diagram (https://lekh.app/diagram.html). The core logic was written in C++ and is being used in Android and iOS apps. I wanted to make a collaborative web version of the app. Initially I thought I would have to rewrite everything in Javascript. But when I first tried to compile all the c++ code into web assembly, it was around 4M of web assembly. And the performance was awesome. I was pretty satisfied with 4M. Then I started developing the Lekh Board (web version of the diagramming app). Later in the development phase, I realized there is a flag which I can pass to reduce the size further. Then I got the web assembly size ~1M.

IMO, it has been mainly a price game between AND and Intel for quite some time

It has custom diagramming and and shape recognition engine

Intelligence mode is what it differentiate from other whiteboard in the market now

I see this on dark.dev for web

"Warning: While in development, web support is available in the beta channel"

What is your experience? Is it OK to use this is in production app. Right now I need a web and desktop app and curious to know if Flutter can be used. But I see the Flutter web is beta quality and Flutter desktop is alpha quality as of now

Flutter Web does it's own rendering via canvas, so accessibility is off the table for now and there is no easy path to get there.

That alone should kill it for most production use unless it's an internal tool.

("should" because many apps sadly just don't care)

edit: I was wrong, see below. Glad to be wrong actually, because Flutter is great.

Apparently this is not true. It does support accessibility.

That isn’t true and hasn’t been for a while. It’s nowhere near “web native” still but it is yet to even get a non beta release so I will give it some slack.

But I think Flutter is probably the best hope out there right now for the ever elusive dream of write once and run anywhere with native performance.

I wrote very similar article long back. http://www.avabodh.com/cin/cin.html
