COVID-19 notes: plague month four
1. "This solves so many problems!"
Humour saying the unsayable. We have too many old people. We have too many old people clogging our health systems and care homes. We can't afford decent support while no-one will countenance those helpful little pills for the elderly infirm. And now nature has come along to solve our problem.
As regards the political and economic conditions of the poor, the Black Death was a real public good.
Subsequently.
2. Follow the Money
I was doing calculations (parameter estimations for logistics curves) to try to figure out when the epidemic will finally burn itself out. But the James Bond people have helpfully solved the problem (was ever a film better named!). "No Time To Die" has been postponed to November.
3. There are two mutations, 'L' and 'S' in the world (so far)
The more aggressive 'L strain' appears to be less prevalent, possibly due to increased suppression due to it being more apparent to surveillance (and quarantine). However, we are in the earliest stages of the pandemic globally and the number of mutations correlates with the number of viruses in replication.
It is unlikely that the virus is at its peak of fitness in current incarnations. And RNA viruses have a hundredfold greater mutation rate than DNA viruses.

Rhetorical question: how many people are currently envisioning themselves a few months from now lying pallid and dizzy in their beds while slowly drowning from fluid build-up in their lungs?

Curious dreams
It's been a while since I've had a cold. The sore throat hit on Thursday afternoon although it lasted less than a day. By Friday afternoon I was wiped and retired to bed, where I remained for the next 24 hours. The virus makes you weary: your consciousness diminishes, you doze, you have strange, obsessional dreams.
I dreamt about weaponizing drones to drop grenades .. but that's already been done.
and a similarly-chilling and brilliant "Fail-Safe", Eugene Burdick's and Harvey Wheeler's dramatic account of an American nuclear bomber squadron which is mistakenly directed to target Moscow. Due to an equipment malfunction, they can't be recalled.
It does not end well.
Thankfully, now I'm recovering: all those fever-dreams must surely be receding.
But .. a month ago, I wrote this spoof-ish piece arguing that due to shortfalls in conventional military provisioning, the UK will (or should) end up emulating Russia's 'small-nuke warfighting doctrine' (as memorably described in "War With Russia" by General Sir Richard Shirreff) - rather than the current MAD posture.
Obviously this is politically unsayable by any conceivable British administration .. but then I read that the Americans plan to do exactly that - and they even have a big enough military already.
Since the Brits tend to do stuff for the Americans which they find politically difficult, some new (multi-user?) development contracts could be incoming for the MoD .. .
I dreamt about weaponizing drones to drop grenades .. but that's already been done.
"Guerrillas have been using commercial drones since 2015. Islamic State (IS), one of the groups active in Syria, makes extensive use of quadcopters to drop grenades. In 2017 alone the group posted videos of over 200 attacks."The Economist this week continues:
"Small drones are surprisingly hard targets, however. Iraqi forces in Mosul used to joke that trying to deal with an IS drone attack was like being at a wedding celebration: everyone fired their Kalashnikovs into the air with no effect.My other dreams were reminiscences of Herman Kahn's legendary "On Thermonuclear War";
A recent American army manual describes small drones as “very difficult to defeat using direct fire weapons”. A single rifle bullet is likely to miss. A shotgun would work, but only at close range, and would mean that squaddies had to carry around an extra weapon all the time on the off chance of a drone attack. Also, since drones are not of standard sizes, the range to one is hard to estimate.
The manual therefore suggests that rather than aiming directly at a drone, the entire squad should fire their weapons at a fixed point ahead of it, hoping to bring the craft down with a curtain of fire. The manual also advises commanders that the best course of action may be “immediate relocation of the unit to a safer location”. ...
"A similar problem applies at sea, where billion-dollar ships might have their defences overwhelmed by squadrons of cheap, jerry-built drones. The mainstay of American naval air defence is Aegis, an orchestrated arrangement of radars, computers, missiles and cannons. The short-range element of Aegis is a Dalek-like, rapid-fire cannon called Phalanx, which spits out 75 rounds a second and can shoot down incoming cruise missiles. This will not cope well with lots of small drones, though.
The navy is now upgrading Aegis’s software to handle multiple simultaneous incoming targets by scheduling bursts of fire to destroy as many members of a swarm as possible. It is doubtful, however, whether one gun could account for more than a handful of attackers coming in from all directions at once. An unclassified study suggests that it could be overwhelmed by as few as eight. [!]"
