I'm a Lecturer in Computer Science at Brunel University London. I teach games and research simulations. Views are my own :).

The year is almost over, so I want to spend a bit of space reflecting on it. My post about 2019 last year only ended up with 4 upvotes, so I'll go for a shorter one this time :).

2020 in my life

No need to self-indulge this time around. We've had three lockdowns here, my wife Moqi got COVID-19 in spring, and broke her pinkie in that same period. Then in autumn I ruptured my Achilles tendon. Work-wise we both all got pretty much all our proposals rejected this year, and the crowdfunding project we set up didn't really take off either.

This was not a good year for us (or most others I presume), but there were upsides. At least all of us are now healthy again, the kids are doing pretty well, and I managed to have much more of a social life than in the last few years. Also, I hung out more with several online communities, including the one here at Coil of course :).

2020 in the world

Let's skip this one for this year. I'm sure you heard enough about the world in 2020 already! I'm very relieved that Biden got elected and that there are working COVID-19 vaccines though.

A few lessons I learnt in 2020

I definitely learnt a few big lessons this year! they make my 2019 lessons look rather silly to be honest. So here we go:

  • At the start, I would track a lot of things around work, exercise and other things in a spreadsheet. But when I stopped doing that after ripping my tendon, I freed up a huge space in my mind! And I realized that less can be more when tracking my own life habits, because:
    • Tracking takes time and effort.
    • It also takes up mental space when I don't record things, because I think about all the trends I have in my tracked behaviors...
    • And the more things I track, the more ignorant I become of the things I do not (or cannot) track!
  • The lockdowns taught me how much of the “pressure” I experience in life are actually due to self-imposed obligations! Stripping them felt like a huge relief...
  • I'm getting older... The day before I was promoted to Senior Lecturer, I ripped my Achilles tendon in a seemingly random freak accident, where I just started a gentle jog. Clearly I have to be a bit more careful with putting strain on my own body.
  • Small bad habits can have huge consequences. You see, the job obviously didn't cause my tendon to rip. I also did a proper warmup during that practice. But a few days earlier I did cycle around with a saddle that was too low, because I was too lazy to adjust it, and kept my foot at an awkward angle for 2 hours of cycling... The punishment was large.
  • And lastly, a light one: Even though virtually nobody outside the US uses Coinbase, people still massively dump XRP when they do a partial delisting! (by the way, people shouldn't use Coinbase imho: Uphold and Binance are much better :)).

Wrap-up

I'll look forward to 2021 in a next post soon! :)

....well, sort of that is.

I was supposed to get my boot removed at Northwick Park Hospital tomorrow, but unfortunately due to ill doctors my appointment got moved to next week Tuesday.

So I still have 4 more days of “the boot”.

But on the upside, I am allowed to bear at least a little bit of weight on it now. So strictly speaking it's not the last day of my boot, but it is the last day that I'm not allowed to bear any weight on it ;).

In other news, you may recall my previous post about our Crowdfunding project, and that I would donate my Coil boost over the past month to the project. Well, the boost is in:

So that is $52.84 for the Crowdfunder! In addition to that, I collected 40 XRP through gfam.live and another estimated 12 XRP through mg.social (including a donation from Matteo which already went half to charity!). At current rates that equals to 0.63*52 = $32.76.

So overall, I will be transferring $85.60 to the crowdfunder, or £62.91 in total. Not a bad result! :)

Now the crowdfunder with the COVID-19 Risk Map is not the only project we're undertaking to try and make a positive difference to the wider world. In fact, we've been really busy with a project centered on our migration simulations as well.

But with the Christmas break approach, that project will have a break as well, so I'm very keen to get back on here and start sharing stuff more often again!

I put a joke poll out on Twitter a few days ago, asking people how they think 2020 will end. Here's the five responses I got:

But joke polls aside, while we really have a Happy End?

Well, as part of this second edition of the Fork, you'll get a few different endings from me! And I deliberately kept it in the near future, so that you can freely mock and ridicule this post on the 1st of January 2021, when you are enjoying your socially distanced fizz ;).

As usual, I go from pessimistic to optimistic, and throw the strange one in ... at some point :).

(1) End of Happy.

2020 will end as a proper Annus Horribilis. In a nutshell:

  • The vaccines turn out only to work for specifc strains of SARS-CoV2, whilst the mink industry in Europe has been helpful in ballooning the number of strains to close infinity.
  • As weather gets colder in the Northern hemisphere, SARS-CoV2 goes on a massive rampage in Europe and Northern America. Christmas will be Cancelled this year.
  • The stock market crashes over Christmas due to vaccine disappointments, and continued uncertainty about the US election, where election officials now are being blackmailed to further delay the transition.
  • The conflict in Ethiopia will spiral further out of control.
  • And specially for @aussieninja: Tesla identifies a manufacturing error in their batteries, and end up recalling all their Model 3 cars over Christmas.
  • Protests erupt across the UK, as the government fails to secure a deal with the EU and splurges on missiles and warships whilst poor children are still left starving over Christmas.
  • And to top it all off, Coil shuts down without prior notice.

There you go, is that bad enough for a pessimistic 2020 scenario? ;)

2020 was lousy, but the final two months give hope for better times ahead:

  • Trump fades into the background, but Biden gets confirmed quickly as new president, and the transition is relatively smooth due to the professionalism of the other Republicans.
  • The SARS-CoV2 pandemic peaks at the end of November, but it's clear the worst is behind us by the time December has ended.
  • The COVID-19 vaccine works...fairly well. It's already been used on some of the most vulnerable people by the end of the year, and it has incentivized many others to stick better to the lockdown measures now that the cavalry has arrived. The pandemic is far from over, but at least the world has found a method to the madness.
  • Britain doesn't strike a deal with EU (hahahaha!), but at least Boris had the common sense to arrange a last-minute extension. Nobody is precisely sure how that was accomplished though.
  • Christmas is not cancelled, only the major group events.
  • The crypto hype continues into December, delivering some smiles on masses of people who otherwise had a terrible year.
  • I attempt to make a video post using Cinnamon, but it turns out hilariously poor!

(3) Boom!

No further ado, let's roll with the third outcome!

  • Donald Trump returns to sanity, Putin steps down as president, Xi Jinping releases all the people in Xinjiang.
  • Boris Johnson reaches a deal with the EU, and caves in to Marcus Rashford's demand for free school meals for poor children in the UK.
  • Ripple moves to the UK and rescues the impending crash of the UK economy (ha!).
  • Vaccines get rolled out all over the place. Companies are waiving patents and everyone works together to already get the first million people vaccinated by the end of 2020.
  • Peace returns to Ethiopia.
  • My leg actually recovers properly and I'll walk sort of normally by new year.
  • #FlareNetworks decides to give the Ripple share of Spark tokens to all the poorest people in the world: the price then booms after the tokens are issued, lifting millions of people out of poverty ;).
  • The Coil 2.0 blogging platform gets released, blowing everyone's expectations, and lastly.
  • Someone invents a 200-seater electric passenger place!

Nobody is perfect, but Americans desperately need Joe Biden and Kamala Harris.

I'm relieved that they have won the election.

Their term starts on January 20th, 2021.

But SARS-CoV2 isn't waiting for that unfortunately.

(Source of both images here: Worldometers)

So Americans are in need of Donald Trump as well.

They need him to behave like an adult, bring actual relief instead of comic relief.

There are lives at stake, and the clock is ticking.

Well, a brief personal update here. I went to Northwick Park Hospital yesterday to get my cast removed, and learned a lot more about my injury thanks to a very communicative and competent doctor.

Indeed, it was a full Achilles tendon rupture, and the gap between both ends was 1.1-1.3 cm three weeks ago. This time around they replaced my cast with a boot (see picture above). Surgery is not a good option, because the rupture is actually too high up for that (it's in my calf).

I cannot bear weight on the boot, and I will need to wear the boot for 8 weeks. Initially with 4 wedges in it, but then removing a wedge myself every 2 weeks.

It's a bit of a shock to be largely immobilised for such a long period, but at least I know much better what to expect now.

As for the walking, I purchased an iWalk 2.0 (see above), which I hope will help me to walk more than 100-200 meters away from the house. I'll let you all know what my experience with it is!

Like many other countries, we are having a severe COVID-19 problem here in the UK today. In this post I share my opinion on the causes and what I think we should do.

Indeed, the situation is dire:

To begin, I'll try to summarise what is probably going wrong here.

August: the bend upwards

After hitting a low on the 29th of July, August clearly marks the starting point of the second wave of COVID-19 in the UK. There are four things of note here:

First, one measure that was imposed in that month was the Eat Out to Help Out scheme, where everyone got a 50% discount when eating out on Mondays, Tuesdays or Wednesdays throughout the UK. Economically the scheme was a success, but inevitably more people shared indoor spaces, which inevitably led to an increase in cases again.

Second, August marked a period in general where the lockdown restriction were relatively light. But even the measures that were there were not followed very rigorously, as only 18% of the people fully self-isolated when having symptoms. The Independent has a clear piece on it as well, featuring this chart for clarity:

One could argue that people may have gotten tired of the lockdown measures, but if you check the paper you find the reasons are more complicated, involving for example:

  • That only ~60% of the people can correctly identify the main symptoms of COVID-19 (cough, high temperature, loss of smell and taste) throughout this period.
  • That the compliance rate itself actually only dropped a little bit between early April (starting phase of the lockdown) and August. In fact, the change is not even statistically significant.

Third, a lot of people went on holiday abroad, especially to countries like France and Spain, which saw a surge of cases already in August. In all fairness, this has likely led to a sizable number of new infections in the UK, and with a proper test and trace system, once could actually find this out entirely. This is because the SARS-CoV2 virus does tend to mutate, allowing you to track clearly the origin of most infections.

Reason 4: Track and Trace

The fourth and foremost reason is the failing track and trace system. Track and trace failed in February, because the authorities were caught prepared for the wrong pandemic, and many cases had already spread under the radar before everyone realised the extent of infections in the UK. We then entered a heavy lockdown in March, and track and trace was instated to make sure such a failure would not occur again.

Given that 40,000 funerals had taken place in the first few months, one would expect the government to realise the importance of this. And they did to some extent by investing £11 billion into a track and trace system. Some of this money went to a company named Serco, but the NHS itself and Public Health England also play a major role in the test and trace system.

However, the track and trace system failed again. Rapid testing is essential to limit the spread, but in August tests were often delayed or not done at all. This gave rise to an increase in COVID-19 cases leading into September.

September: the blooper

Already it was clear that the test and trace system was not effective in stopping the spread, as the cases per day steadily started to increase.

But the big, sudden peak towards the end of the month is caused by a humiliating blooper involving Microsoft Excel caused Public Health England to miss out on a whopping 15,841 COVID-19 cases. The exact blooper? They used a spreadsheet with too many columns. This blooper caused a huge gap in the track and trace system, and the number of cases to balloon even further.

Indeed, aside from lockdown measures and everything else, this error has caused a large amount of damage. Together with the overloaded test and trace system, we suddenly find ourselves in the situation we are in now, here in October.

October: what do we do now?

Boris Johnson enacted a three Tier system of restrictions, with London currently in Tier-2. It's a step in the right directions, but with the number of cases still growing and people exhausted with the lockdown, they may comply with the measures (even) less now. So I doubt this will work well.

One of the biggest problems here is that we are still driving blind. Test and trace cannot cover most of the contacts, many cases in general are simply missed, and few people are measuring who is complying with the lockdown measures and who isn't. Letting the pandemic rage on is not an option. Hospitals will be overwhelmed, and the mortality count will quickly grow to exceed 100,000, perhaps even 200,000.

So the only thing people can reasonably aim for to reduce the number of cases quickly, fix and improve the test and trace system (might I suggest a port away from Excel?), and get the pandemic to a level where the test and trace can be done without major shortcomings.

The three Tier system can help to achieve that, but only if it is strongly and strictly enforced (which it is not, due to incessant budget cuts on law enforcement in the past decade).

The alternative offered by Labour is to enact a stricter “circuit-breaker” lockdown for a limited period of 2-4 weeks. But here too, the efficacy of that measure depends strongly on how well it is enforced.

Being rigorous: enforce and compensate

In general, the problem with this pandemic is that you can't afford to roll out half-baked, half-assed, half-enforced solutions to fight it.

A properly enforced lockdown will work (see New Zealand), massive adoption of masks will work (see Japan) and comprehensive testing and tracing can work as well (see Korea). But whatever it is the UK chooses to adopt, it needs to be done rigorously, not in the half-baked Pipo the Clown fashion that has been done now. And it also needs to compensate those who are most heavily hurt by the measures that need to enacted.

So pick an approach, throw the kitchen sink at it and make sure it's fully enforced and compensated for.

As for my personal preference: I think the best option is a very strongly enforced 3 week lock-down followed by (a) universal mask-wearing outside of the household (yes, that means keeping pubs and restaurants closed and properly compensating the owners) and (b) vastly improved track and tracing work. That way, the UK may be out of the woods relatively quickly, with somewhat limited further damage to people's health, well-being and financial stability.

Today I realized that there are perhaps too many Dutch-style blunt opinions in the Netherlands, and not enough of them elsewhere. Time to fix that a little ;).

Let me start with Covid-19. I'll talk a bit about Trump, a bit about nonsense studies/posts, and a bit about elevators. I might cover other stuff in a later post separately.

Trump

I'm not sure what is messier: the way the White House gave updates about Trump, or the way Boris Johnson gave updates about the current lockdown measures. But at least for Trump there is a good timeline of his condition, namely on Forbes here.

My take on it? I'm pretty sure he's had Covid and I'm pretty sure he's still infectious (nobody has seen any negative test results, and I cannot think of any incentive for the POTUS to hide such results). So if you see him talking near any other person without a mask, you can be assured that he's deliberately spreading sickness without even turning on the volume. Last time around, I expected Trump to win the election: this time around I frankly find it too cynical for my own taste to be expecting that...

Covid-19 Superforecasters

The research field of Covid-19 forecasting took a big blow this week.

First there were headlines nationwide for a study form Edinburgh, which has issues. In the study, Rice and his colleagues claim that lockdown actually increases the number of Covid-19 deaths, using simulations of the CovidSim code. The detailed paper is here, and a Guardian article here.

The paper has several dangerous passages which can be utterly misleading when taken out of context, such as the following one:

“We confirm that adding school and university closures to case isolation, household quarantine, and social distancing of over 70s would lead to more deaths compared with the equivalent scenario without the closures of schools and universities. “

They decided to conclude this after having tested the CovidSim code (which I reviewed back in the days here) under a few different situations. Now simulation codes are useful, but they really are not the same as physical reality. I think we must be MUCH harsher on those who pretend that they are.

In the case of CovidSim there is one huge simplification the researchers chose to ignore: the code has the same death rate per 100,000 infections over the whole period if you run a simulation over two years. But in reality the death rate has dropped by more than a factor two (!) due to improved facilities and treatment. It sounds simple perhaps, but it's this little assumption that completely underpins their outrageous conclusion.

And indeed, the clumsy sentence was indeed predictably taken out of context by the Daily Mail among others, leading to train-wreck headlines such as:

Source: *https://www.dailymail.co.uk/news/article-8817075/Coronavirus-lockdowns-kill-herd-immunity.html*. (Btw. I love how beautifully this header renders in my browser)

The fact that *any* researcher is able to push this kind of crap into an Impact Factor 30 journal means only one thing:

We Covid-19 spread forecasters are facing a huge credibility problem, and crap peer review is to blame for it.

More bad forecasting news: Youyang Gu quits

Anyway, this scientific insult was not the only blow the community had to endure. Additionally, one of the most skilled forecasters in the US (perhaps even the most skilled one), Youyang Gu, decided to call it a day and focus on other Covid-19 related data issues. It's a sensible decision, but let's hope others can step up to the plate to do decent forecasts from now on.

PeakD Covid-19 Nonsense

As some of you may know, I play Splinterlands these days now, and one of the platforms I'm exposed to is the Peakd blogging platform.

The platform, arguably a competitor to the Coil blogs, has some merit and potential, but for me its credibility was instantly flushed down the loo when I saw this Covid-19 post. There's no need to click/read it, the tl;dr is that it describes a Covid-19 conspiracy theory involving the Rockefeller Foundation, and that it has a whopping 176 upvotes.

I was the first to actively downvote it (it still has only 1 downvote), because apparently I am the only sane person who has read it so far.

Covid-19: the elevator edition

Lastly, a little bit about elevators. I will be short on this one: don't get stuck in an elevator with a Covid patient!
