Recently, the US President, Donald Trump, made the decision to pull the US funding from the World Health Organisation. This of course has been widely condemned, and will likely get challenged, but in the meantime it made me wonder what the rest of us could do.

No, I’m not suggesting acts of violence at a “democratically” elected head of state, as tempting to some as that may be.

The US contributed a little under US$900M last year to the WHO. Could we crowd-fund that?

I was thinking about what platform would work best for this, turns out, I don’t need to. The WHO are taking donations directly.

If 40 million of us, world wide, each donate US$25… we will exceed the funding once provided by the U.S.A. Time one president was shown how he’s just another brick in the wall!

We don’t need the U.S.A. to fund the WHO, we just need US. I did my bit… how about you?

COVID-SARS-2 is a nasty condition caused by COVID-19 that has seen many a person’s life cut short. The COVID-19 virus which originated from Wuhan, China has one particularly insidious trait: it can be spread by asymptomatic people. That is, you do not have to be suffering symptoms to be an infectious carrier of the condition.

As frustrating as isolation has been, it’s really our only viable solution to preventing this infectious condition from spreading like wildfire until we get a vaccine that will finally knock it on the head.

One solution that has been proposed has been to use contract tracing applications which rely on Bluetooth messaging to detect when an infected person comes into contact with others. Singapore developed the TraceTogether application. The Australian Government look like they might be adopting this application, our deputy CMO even suggesting it’d be made compulsory (before the PM poured water on that plan).

Now, the Android version of this, requires Android 5.1. My phone runs 4.1: I cannot run this application. Not everybody is in the habit of using Bluetooth, or even carries a phone. This got me thinking: can this be implemented in a stand-alone device?

The guts of this application is a protocol called BlueTrace which is described in this whitepaper. Reference implementations exist for Android and iOS.

I’ll have to look at the nitty-gritty of it, but essentially it looks like a stand-alone implementation on a ESP32 module maybe a doable proposition. The protocol basically works like this:

  • Clients register using some contact details (e.g. a telephone number) to a server, which then issues back a “user ID” (randomised).
  • The server then uses this to generate “temporary IDs” which are constructed by concatenating the “User ID” and token life-time start/finish timestamps together, encrypting that with the secret key, then appending the IV and an authentication token. This BLOB is then Base64-encoded.
  • The client pulls down batches of these temporary IDs (forward-dated) to use for when it has no Internet connection available.
  • Clients, then exchange these temporary IDs using BLE messaging.

This, looks doable in an ESP32 module. The ESP32 could be loaded up with tokens by a workstation. You then go about your daily business, carrying this device with you. When you get home, you plug the device into your workstation, and it uploads the “temporary IDs” it saw.

I’ll have to dig out my ESP32 module, but this looks like a doable proposition.

I’ve had this stuck in my head all day…one sorta has to pronounce “Corona” as “Crona” to make this work… Apologies to John Carter and The First Class…

Do you remember back in olden day, (wo-oh-oh)
when everybody lived a care-free way (wo-oh-oh)
whatever happened to the boy next door,
now sneezing, hiding behind the bathroom wall!

Remember dancing at the high school hop
The dress I ruined with the soda pop?
Quarantine didn’t mean a thing
Hundreds of people getting in the swing!

Corona baby, Corona baby, give me your hand
let me share what I can remember
Life as before we all got caught
in the lock-down.
Corona baby, Corona baby, you can’t understand
why society was so quick to dismember.
Days in the sun, to lyin’ on our bum every day!

So we’re all working from home at the moment with COVID-19 wreaking havoc… and of course the toilet humour has been flowing like a fountain…

Our workplace’s #random channel on Slack…

Sounds like a great start-up… of course the idea has only been around about 400 years. 🙂 Sometimes truth is stranger than fiction.
