Author here. I made this demo and a related matrix-matrix multiplication demo [1] back in 2015 for Robert van de Geijn's Linear Algebra: Foundations to Frontiers MOOC class [2]. In the light of Spectre attack and recent browsers' changes to reduce precision of timers, I remembered of this project, and decided to check if it still works now, 3 years later. Surprisingly, it still works well!
The source code is available on GitHub [3].

- madez 9y agoCould you make the website viewable without JavaScript? Edit: I think the downvotes are unjustified. For clarification, if that wasn't clear by context, I don't expect to get the JavaScript test results from my computer while viewing the website without JavaScript. Demanding that would obviously be nonsense. Rather than that I assume there is information on that website that is interesting to read even without using JavaScript personally. Or is using JavaScript now a requirement to learn about JavaScript?
- StavrosK 9y agoI guess you'd have more luck if you had asked "can you make some examples accessible for those of us who don't run JS?".
- madez 9y agoI didn't know what to expect to see. I vaguely assumed to see some text and data. That's why I carelessly formulated my question like I did. Still, I think the difference is small and my question wasn't extraordinary.
- Cyph0n 9y agoIs there a particular reason why you can't enable JS yourself? Metered connection? Low-end machine?
- Tehnix 9y agoMetered wouldn't really matter would it? Scripts are still downloaded, right? (never had JS off, because the web)
- swsieber 9y agoMetered could matter - it's very easy to disable downloading of any non-inlined JS (like with uBlock)
- madez 9y agoI consider it an unacceptable form of code deployment. It's unsafe in the computing sense, and leads to a ecosystem where users are less and less in control of the software they use.
- Mister_Snuggles 9y agoI use uMatrix, this site just shows up as a white page until I allow it to load some JS from a third party. Once I allow the JS, I see a graph that gets built without any explanation of what that graph means.
- detaro 9y agoThere's only a graph of the results, so you are not missing any other content.
- madez 9y agoThanks for the info.
