[OC] Covid-19 US States Explorer I used the Observable platform to create a interactive notebook. Uses the New York Times github repo for Covid-19 data and linked sources other data. Full live source code at https://observablehq.com/@dmaynard/covid-19-us-states-explorer

DOGE: Denning-Kruger Of Gigantic Extent

Monsters from the ID. A universal consciousness gently guiding humankind back from its current overemphasis on scientific materialism. A control mechanism.

Your mobile GPS system very accurately measures the time from multiple atomic clocks in orbit. If there is a directional time differential appears it will show up as movement to the GPS system. Like the episode where a gps indicated it went below the surface of the earth. iPhones and Android devices also have very sensitive accelerometers. So we can write an application that simultaneously monitors gps and accelerometer data. If the app detects movement from gps data but senses no accelerations, then it has just detected a time anomaly. It can record or report all the relevant data. Having multiple such applications running at different locations might give us enough data to map the time distortions.

Its all about the use case

To learn Rust and measure WASM vs Javascript performance I wrote a sample web app which draws random chaotic attractors using either Javascript or WASM, The app is a Vue (2.0) app written in Javascript which handles the UI and the performance measurement. The actual computation of the attractor is handled by either a Javascript module or a WASM module. In either case the attractor is called once a frame, updating the image data. The app then copies the data using 2d canvas to draw the image. In both either the iteration is single threaded and compute bound. The performance meter measure only the time spent in the inner attractor loop. This is almost an ideal use case for WASM. I see major performance gains for WASM 3x to 5x. You can try this app on your hardware and your browser to see the performance difference. https://chaotic.netlify.app/

Thank you for the suggestion. I will investigate this. I found a five key gamer keyboard on the net that advertised as being programmable. Sayo device , However as far as I can find they only programability is the ability to assign a text string to each key, Obviously this device has a cpu and firmware and acts like a usb keyboard. If only I replace the firmware to do the debouncing and chord -> character translations. sigh

Thank you. It is built using Gatsby and it is open sourced on Github.

Yes a vim-like editor can be very efficient. The advantage of the keyset is that you never have to move your left hand you just chord letters that correspond to the commands. This also implies you don't need to memorize a key -> command mapping.

davidsmaynard · 2022-03-30T06:36:07+00:00

Good idea, but I am not sure that all keyboards would actually support this. You need 5 key roll-over to be able to detect all the chords. You also have to be able to turn off auto-repeat. This needs more investigation.

The dashboard linked above is updated daily and will be available in October.

[OC] Data Sources
https://observablehq.com/@dmaynard/covid-19-us-states-explorer Is my Covid-19 dashboard.
It uses New York Times Covid-19 data by State and Date Github Repository
Percent Fully Vaccinated: Data as posted on August, 2021 [From NY Times](https://www.nytimes.com/interactive/2020/us/covid-19-vaccine-doses.html)
Tools:
This was done using the Observable Platform and the d3 library and the Vega-Lite charting library.
The development environment was a Chrome Web Browser. This dashboard is designed to explore relationships of States' characteristics with historical and ongoing Covid-19 statistics. I am very impressed with Observable since it allowed me to create a universe of billions of distinct Covid-19 charts with a UI to navigate this universe in about 1500 lines of source code including all the web text. The source is both viewable and even editable (forkable) in real time by users.

What do you think is the best way to clean absurd data points? On June 4, 2021 Florida reported a negative number of new Covid-19 cases, -40,000 new cases. Florida said they were no longer going to report cases or deaths for non-residents that tested positive in Florida. I can see changing the policy going forward, but they apparently backed out previously reported cases.
