#rEUnion Manifesto

 Now we've left the EU, I thought I'd write a bit of a blog post on what I think should be the priorities for being able to re-join the EU at some point in the future. I want to start with an assessment of how we got here, as well as a step-by-step manifesto for how we get back. This will take a long time, perhaps a decade or two (it took nearly five decades for Euroskeptics to engineer our exit) so we need to plan strategically for that kind of distance.

Why We Are Here

The easiest explanation for why the UK has split from the EU is that we're following a parody of the 1930s. In a much earlier blog post from 2008 on the subject of the global crash. Here I wrote:

 "The 1929 Crash was a culmination of 5 years of massive stock market growth which was ultimately boosted by heavy speculative investment. The market initially recovered over the next several months of 1930, but this was not enough to prevent the subsequent Great Depression and corresponding global recessions in Britain and more importantly in Germany (where the economic (and social) instability lead directly to the the rise in power of extreme political parties and subsequently the Nazi dictatorship and World War II)."

"So, when we come to look at the Crunch we actually see the hallmarks of previous crashes all over again. We see deregulated markets leading to a financial boom and subsequent serious bust."
"What we can predict is that this is only the start of the problem"

You can read the rest in the actual blog post itself. My concern at the time - although I didn't state it directly, because I didn't think that governments would actually do it, was that we would follow the same path as the 1930s, because we know what happened then.

However, I was wrong. In reality we followed pretty much exactly the same path, with the exception of the US for the first 8 years and the UK for the first two years which implemented a half-baked Keynesian solution which refinanced banks at the expense of refinancing people. In the EU they followed the path of austerity.

The Five Steps Of Failure

The 1930s followed a basic pattern which we've been roughly copying. This can be summarised as:

  1. A global crash which lead nations to..
  2. Implement austerity in order to 'manage' their finances.  This is a classic right-wing economic approach which treats national economies like domestic economies. It cannot be emphasised enough that it doesn't work. I have a blog entry from 2015 which explains why they are not the same. Nevertheless, the EU imposed austerity (or SAPs) from 2009 and the UK imposed it on itself from 2010. In reality austerity causes..
  3. People to react by becoming more politically extreme, in particular by shifting towards right-wing Nationalism. I think the reasons for this are pretty simple. When people are faced with austerity, they spend far more of their time looking after their immediate needs and so their cognitive horizons shrink. In essence austerity prevents people from looking at the wider problems and so people are lead to more populist, political thinking: simple immediate solutions rather than complex wider solutions. But right-wing nationalism has the edge, because the shrinking of horizons forces a more nationalistic viewpoint. What happens outside of those horizons is threatening. This leads to..
  4. The destabilisation of Europe. In Austerity Europe of the 1920s (post Versailles) and 1930s (post Wall Street Crash), both phases lead to destabilisation from Fascist governments. Italy broke away in the 1920s under Mussolini and Spain entered a (partly Nazi supported) civil war in the early 1930s. And of course Germany went Nazi in the very early 1930s. But the same patterns of political destabilisation appeared across Europe and the US; ranging from Oswald Moseley's Black Shirts to the America First movement in the US. Europe was destabilised.
  5. Ultimately, because Nationalist governments have a relatively local focus, they are lead into conflict with either themselves or other countries. So, the whole process ended with War.

Now, it's understandable that the EU, if lead largely by Germany (which I think essentially has control of the Eurogroup) would choose austerity, rather than Keynesianism. And the reason is that from the German perspective in the early 1920s, the reaction to the conditions for the Treaty of Versailles was to print money. It was this printing of money that lead to hyper-inflation and the emergence of Nationalist and subsequently fascist groups like, obviously the National Socialists. Thus Germany, in particular its Ordoliberal school of economics has a deep aversion to non-austerity: they believe in keeping a tight control over money, but this is, at least in some circumstances, like this one, the wrong lesson.

With the final step of Brexit under a hard right, nationalist government we are fully into Stage 4. It's taken a whole decade of austerity to get there (cf 1919 to 1929) and there's been a lot of resistance, but it's safe to say we're at the beginning of step 4 now.

The important thing to note in all of these, even above the individual steps is that the further we progress with them, the harder it is to turn around and recover.

So, in the 1930s, the US recovered first because it didn't go very far down step 2. It pursued poor policies during the Hoover period (Dust Bowl, great depression), but then FDR was elected and he instituted the New Deal, which dug the US out of its mess, thus avoiding steps 3 to 4 (though there were plenty of elements of 3 in the US of the 1930s).

The UK managed to take some steps in the late 1930s towards economic recovery, but was still partially in the grip of appeasement (i.e. Nazi Sympathy) at the outbreak of World War 2.

The Manifesto

1. A Common Understanding Of The Root Problem

Without being able to agree on the five steps above, we cannot agree on the root cause of the problem. At the moment the pro-EU movement has literally no agreement. The consequence of this, for example, means that because we don't think austerity is the primary cause that lead to World War 2 (and there are other, specific concrete political critical events and causes), we have no insight into the underlying forces that drove Brexit and no map for where we're heading. For us, Brexit came out of nowhere - just individual Euroskeptics who forced a decision on the Conservative party. That was something we wouldn't have predicated. Also, we don't know what's coming next, because we only see the problem in terms of the issues Brexit presents us as a country, in other words, we have a Nationalistic view of Brexit where the EU plays the part of the good guys and we're constantly reacting to the situation.

And our myopic view of the EU as "the good guys" is what also prevents us from criticising the EU (or rather in this case the Eurogroup) where it is part of the problem. i.e. because the Eurogroup is pro-austerity, British Europhiles are pro-austerity. This position has to be rejected. By rejecting austerity as reasonable reaction to the crash of 2008 Centrists will be able to work together with left-wing Europhiles (though it'll be harder to work with right-wing Europhiles).

But to re-iterate, without a common unerstanding of the root problem, we have no control over Brexit.

2. A Common Narrative

The Remain campaign and Remain movement, to this day, 5 years later is obsessed with economic technicalities as a foundation for EU membership. This is a mistake.

The primary reason why Brexiters won was because they have a narrative about Britain as the plucky buccaneers that can do anything when not hindered by the continent. The EU plays the part of the oppressive King or evil dictator and Brexit is about being free of that. All Brexiter arguments are driven by this sense of identity, even though it's inaccurate.

For us to regain the initiative we have to have a narrative about Brtain as belonging with the EU. We need a narrative that says that our natural place is alongside the rest of the continent: helping to make its decisions; supporting it at every step; sharing with its culture, its history, its people, its languages and its purpose of diversity, responsibility and liberation.

Note how 'belonging with' is emphasised. The 'with' is important because we need to convey a peer relationship, not a subservient relationship.

3. Addressing Media Responsibility and Accountability

This is a short point. 80% of the media by print during the referendum was owned by tax-dodging pro-Brexit billionaires. Unless this changes we'll almost certainly lose again. Basically we need a law that's comparable to media laws in some of the rest of Europe where firstly, the ownership is based on a Trust which provides a remit for the media's general political flavour (it's OK to be right-wing or left-wing, it's not OK to just be a mouthpiece for the proprietor). The paper itself should be worker owned by the journalists and readers. This applies to whatever form of media is relevant in the future.

Secondly, there needs to be some level of accountability whereby the media can play fast and loose with facts the way it happened with the referendum. For example, to force media to redisplay corrections with the same prominence of the original erroneous articles.

4. Guerrilla Ops (Picking Battles We Can Win)

Ultimately we need to get back in the EU, but in the same sense that Euroskeptics fought a number of minor battles, most of which were fabrications or merely symbolic and most of which they lost.

But to keep up some kind of morale we should pick fights we can win. I would suggest that the first fight we pick is one over Metrification. Arch Brexiters want us to return to Imperial measurements. JRM, for example has mandated imperial units be used in all his correspondence. I would have thought that at the earliest opportunity, they will try and revert back to Imperial measurements for general use.

We should stop this and push back, to get everyone using metric in ordinary day-to-day activities and communications as well as all formal information. Dump Imperial at all levels.

We can win this one too. That's because:
  1. We've gotten used to talking in terms of metres over the past year in a way we never did before.
  2. Educational establishments in the UK will back us up: they won't be bothered, particularly in sciences, to backtrack on 50 years of progress.
  3. Industry will back us, because Imperial units have a direct financial cost. 
  4. The NHS could back us, by switching to e.g. only giving out metric weights for children.

5. Building a Shadow EU in the UK

We should start preparing for a future with the EU, and the way to do that is to build business and cultural resilience. Even though the Brexit deal is thin, it provides for British companies to adhere to EU standards. Thus, by building networks of British companies that operate on that basis, these companies will be forced to exclude business that breaks those rules: they gain financially by EU commerce and companies that don't will find it harder to compete, despite the UK government's attempts to tip the level playing field.

My suggestion for a name: BEBA: the British European Business Alliance.

BECA would be the cultural counter part. The New European could provide the basis for educational material to provide holidays, cultural exchanges and language tuition and importantly instil more of a sense of European identity in the young until the point when we have #rEUnion.

6. Proportional Representation

Remainers failed in the General election in 2019 for a whole host of reasons, but the simplest is that we failed to collaborate in our opposition to the Conservative and Brexit party and they went onto win the election on just 43% of the vote.

The next election will be easier for the Conservatives than this one, because possibly Scotland will be leaving the UK by then and constitutional boundary changes will lead to a net loss of over 20 current Labour seats.

Therefore it will be more imperative for Labour to collaborate with other opposition parties in the 2025 (or 2024) election, against an environment friendlier towards electioneering since the Electoral Commission's powers will have been curtailed by the Conservatives in the intervening period.

The only way I can see for Labour to gain the confidence of other parties is to promise proportional representation if they win - and the form of PR must be specified so that Labour can't pull the same trick the Conservatives pulled after the 2010 election, where a PR referendum was held, but only AV was an option. Future edits to this post will include more references and possibly diagrams!

7. A Robust Mechanism For A New Referendum

With steps 1 to 6 in place, we would finally be in a suitable position for a fair referendum, along the lines of the one held in 1975, which was based on facts rather than propaganda. Media balance would be better, representation of the people would be more equitable; relationships with the EU would be coherent and ready for re-admittance; cultural affinity for the EU and Europe would be higher; we'd have a UK narrative that would fit into EU membership and rEUnion groups would be more easily able to work together.

8. A Formal British Constitution

Finally, and within the EU, a reformed UK constitution could be defined to make it harder, much harder for the UK to be subverted in the way it was up through the Brexit referendum. Part of the reason why we belong with the EU is because of the checks and balances it provides, but the same applies domestically. There's never a substitute for active participation in politics, but the mechanisms within the state should facilitate both representation and accountability in such a way as to protect both security and prosperity for the people.

Conclusion

We've lost every battle since 2008, primarily because we lack an insight into the wider picture and a model for what to expect. We can't get to #rEUnion by carrying on as we are, with the same arguments. Instead we need to find a common framework for why we're here; a common EU centric narrative for the UK that embodies us belonging with it and finally a strategy that addresses all the institutional failings that prevented us from being about to mount a robust defence of our existing constitution.

The end result should put the UK on a much firmer foundation for the good of all within and without the UK, for the rest of the 21st century.

Toggle Booting a PIC MCU!

Before the 1970s people had to boot computers by laboriously flipping a set of toggle switches on the front of the main processor. Today, all computers have built-in boot ROMs and even embedded microcontrollers are programmed using powerful external computers.

I only consider a processor to be computer if it can support self-hosted programming, so I wondered what it would take to manually toggle in a program on an MCU with no computer and minimal logic. I've produced a video based on this blog here.



I chose a primitive 8-bit PIC, because it has a simple programming algorithm, but even so, I have to enter 56 bits per instruction flashed. It was so tedious I printed out the entire sequence and used a ruler to make sure I didn't lose my position. Here's the 11-instruction program itself:

 0 Bsf Status,5 ;01 0110 1000 0011
 1 Bcf Trisc,4  ;01 0010 0000 0111
 2 Bcf Status,5 ;01 0010 1000 0011
 3 Movlw 53     ;11 0000 0011 0101
 4 Movwf T1con  ;00 0000 1001 0000 65536 cycles at 8us/cycle=
 5 Btfss Pir1,0 ;01 1100 0000 1100 3.8s per full blink.
 6 Goto 5       ;10 1000 0000 0101
 7 Movlw 16     ;11 0000 0001 0000
 8 Xorwf PortC,f;00 0110 1000 0111 (Don't care about RMW issues)
 9 Bcf Pir1,0   ;01 0000 0000 1100
10 Goto 5       ;10 1000 0000 0101

You don't need a GOTO start at address 0: if you don't have any interrupt code you can just start your program at address 0.

The reason why it's so tedious is that programming each instruction involves four command sequences:

  1. Load the instruction into (I presume) an internal buffer.
  2. Burn the instruction into flash memory.
  3. Verify the flash memory instruction you've just programmed (always worthwhile as it's so easy to make a mistake).
  4. Increment the address of the PC. Unlike many MCU flash programming algorithms, the 8-bit PICs can only have their programming address reset (by unpowering the MCU, connecting the PIC's /MCLR signal to 12V, then powering the rest of the MCU at 5V) and then incremented. Thus making a mistake (most likely because you've left out a bit or duplicated one) means you have to start again.

In addition, each programming command expects all the data to be entered from the LSB to the MSB, so in fact I toggled in all the commands backwards, reading each line from right to left. So, the first full command really looked as follows (with '|' separating individual fields):

Bsf Status,5 |0|01 0110 1000 0011|0|000010 Bit 5 is RP0, status is 3
  (Prog)     |                     |001000 Bsf is 01 01bb bfff ffff.
  (ReadBack) |0|-- ---- ---- ----|0|000100
  (Inc)      |                     |000110

The PIC needs just two signals to program it: a clock input and data signal. My hardware is (relatively speaking) super simple.

I use an astoundingly primitive 555 timer chip in its monostable (one shot) mode to debounce the clock. All I needed was a couple of capacitors and resistors to give a 0.2s delay and it would eliminate bounce. All the information I needed came from the wikipedia page on the 555 timer.

The data button was a bit more challenging. I used a few resistors and a red LED as I needed Vdd when I pressed the button, less than 0.8V when I let go, but I also needed to enable the DAT line to drive the LED when verifying data and not exceed current limits even if I accidentally pressed the button when the DAT was trying to output. One of the downsides to this approach is that the LED is barely visible on the video, though in retrospect I think I could have halved the resistor values and it would have been fine.

Finally, I needed a 12V programming voltage for the PIC, and then used a basic 7805 voltage regulator to generate the 5V Vdd voltage for the 555 and PIC. The currents are so small I didn't need to worry about a heatsink for the 7805.

On a PIC it's not good enough just to program the flash, I needed to change the internal configuration to stop the Watchdog from resetting the PIC after 4ms and to use the internal oscillator instead of an external RC oscillator. The spec on programming the configuration is rather confusing, because the sequence to go into config mode requires the full 14-bit configuration setting, and then you have to enter it again as a normal programming instruction.

With some experimentation I got it right in the end! With a bit more detail, I started off by finding out how I could enter one instruction (after running the erase command), and then two instructions. I made two attempts to program the entire program - in the first attempt I made a mistake on the last-but-one instruction and had to start again, I videoed both of them so although the toggling sequence is complete and not spliced from multiple attempts, it wasn't the first attempt.

I had a similar problem with the configuration. It took a few attempts at that to get it right and at one point I thought I had configured it to use an external oscillator and couldn't read the flash anymore. In fact I had mis-inserted the VPP to the right of the 7805's IN pin.

So, it's possible, but not very practical to manually toggle program an MCU, but perhaps survivalist geeks might find it useful in some post-apocolyptic dystopia!

COVID-19 Herd Immunity Sim

Why Herd Immunity Doesn't work for Covid-19

This is a simulation of the epidemic for the sake of working out how much herd immunity is needed to protect the population.
The answer is around 90+% (98% in this sim). Herd immunity is mistaken.

Explanation

Herd immunity is designed for vaccines.
In normal epidemics, herd immunity works because the contagion distance between someone who contracts the disease and the next person who isn’t immune is large due to the number of people already immune (depending on the % immunity and infection rate). But here, no one has immunity, so the disease would distribute itself throughout the population and the contagion distance remains small even after nearly everyone has become immune. So in this case, herd immunity is incorrect, despite what you may have heard from our PM saying he’s followed the advice of the chief scientist.

How To Use

The easiest way is simply to press the StartSim button. It simulates a population of 160,000 where each person potentially infects 0.8 people in their vicinity each day until they get isolated (in the example in day 5). The default vicinity is 256 (+/-16 in each direction) and if by chance an infected person tries to infect an already infected person, it has no effect.

You can see in realtime how an infection spreads across the population. Initially it appears to be exponential, but fairly quickly isolation cuts in and people who have it tend to come into contact with those who already have it, so they don't infect so many new people.
So, the epidemic then spreads at the boundary.
As it does so, some people - a few - remain uninfected, by chance and as the disease progresses at the boundary, the mass of people now immune effective protect the very few who have never been infected. But this is a very low figure, because the whole population has no prior immunity and is not vaccinated.

You can play around with the infection rate (<=1) and mobility to simulate a ghastly pandemic that seems to spring from everywhere all at once, but ultimately it has little effect on the herd immunity as it effectively doesn't exist.

Remember, this is only a simulation to demonstrate the lack of herd immunity. It does not really project actual figures for infection, nor are the rates correct, nor the population, nor the mobility, nor the potential impact of warmer weather on the virus.
