Not my king

Not my king

On the whole, I'm in favour of the monarchy, although I suspect that Big-ears will soon be a good reason to lean the other way.

But I'm also in favour of the right to protest peacefully. Holding up a placard saying "Not my king" or "Abolish the Monarchy" should be the right of everyone. And there should be no restriction as to when this sentiment can be expressed - indeed, the death of Elisabeth II is an obvious time to make this point.

So why are the police arresting, or moving on, people who are simply holding up a placard?

This is wrong. Very wrong. There should be an enquiry to find out who told our long-suffering police to act in this way, and whoever was the cause of this policy, should be moved far away from policy-setting.

And King Charles III should support such an enquiry. Or is he worried about what happened to King Charles I in 1649?

Thirteen stone, three pounds

Thirteen stone, three pounds

Over the last few months, I've got some of my appetite back, and I've been putting on weight. Today, I was up to 186 pounds, 84.4 kilograms.

At one point, I was a lot less. Not long after my operation, I was down to 12 stone 8, or even less. In the hospital, they were so worried about my nutrition, they shoved a tube down my nose to my stomach and tried feeding me that way - it didn't work, it just kept me awake all night.

My BMI now is 27.3, overweight. Maybe I need to stop trying to fatten up.

It's beer, Jim, but not as we know it

 It's beer, Jim, but not as we know it

Actually, that's a misquote, but nichevo.

I've never been a big drinker (except in my late teens, when I got bladdered a few times). But I do enjoy a pint of beer, especially in this hot weather.

So when I found that I had liver cancer, and they cut out most of my liver to cure me, I gave up alcohol altogether, including coq-au-vin and other foods cooked with wine.

Six months after the operation, my liver has regrown, and (I hope) is back in business. I'm still not a big drinker, but I still enjoy a pint of beer. Except that now, it's "non-alcoholic" beer.

Which, it seems, isn't what you'd think. In my naivety, I assumed that non-alcoholic means ... no alcohol. But apparently not. Apparently you can still call it "non-alcoholic" if it has 0.5% alcohol . Normal beer is around 5%, ten times stronger.

Some non-alcoholic beers really are devoid of alcohol; you find out when you read the side of the can or bottle.

Right now, I'm drinking about two bottles per day; some 0.5% and some 0%. That works out at about one bottle of normal beer per week, and I'm thinking that my liver should be able to cope with that.

So why drink this stuff? Obviously, not to get drunk. It's because I like the taste, and in this weather, it's a good idea to get lots of liquids.




GET and POST

GET and POST

There are two ways to send data to a web page, GET and POST. GET puts the data into the URL - that means that the data is stored in the server logs and the browser history.

POST is, very slightly, more secure, because it doesn't have the above issues.

If you use https (and you have to use https to use the Barclays services), then all the data is encrypted before it's sent from your end, and only decrypted at the server end. That means that an interloper can find out what server you're accessing (payments.epdq.co.uk, which we knew already) and what port you're using (443, the https port). so the security benefits of POST, and quite tiny.

I use Barclays for running credit cards, and I do it with a program I wrote. I used GET to send the data, because it's slightly easier to implement. But, suddenly, Barclays have woken up to the difference, and they've just told me that as of October 2022, they won't accept GET, everything has to be POST.

There's nothing in my browser history, because I'm not using a browser, I'm using LWP::UserAgent. That is a perl library. There's no history. And yes, the info is in the server logs, but the server is run by Barclays, and they should have it under the most stringent security.

I hate it when they do this. I've been running credit cards for 25 years now. Originally, they could only accept paper, so my database would print out each billing, and we'd ship the paper to our local bank. They would then ship the paper to Poole (except one time when they lost it and didn't tell me until several months later) and some typist at Poole would type it all in again.

Since then, they've been gradually improving their service. The problem is, each time they make a change like this, thousands of businesses all over the country, have to make changes in their software. I've been though this maybe a dozen times now.

The security difference between GET and POST has been known for a very long time. Why have Barclays only just woken up to it? And why do they think it would affect my systems?

Also, it would be nice if Barclays gave a sample working program. Since they haven't, I'll do it.

It would also be nice if someone at Barclays tried to read their documentation. Everything one needs is there, but it can be really difficult to find.

I'm not telling you my id, userid or password, obviously - if you use Barclays to run cards, you have your own. This program works, and I can then parse $content to take action depending on whether the card was accepted or declined.

#!/usr/bin/perl
use LWP::UserAgent;
use CGI::Carp qw(fatalsToBrowser);
print "Content-type: text/html\n\n";
$epdqurl = "https://payments.epdq.co.uk/ncol/prod/orderdirect.asp";

$amount = '1000'; # meaning $10
$cardno = '4111111111111111'; # that's a test card, it will be declined
$expires = '0824';
$transactionid = 'post-test-1';

my $browser = LWP::UserAgent->new;
my $response = $browser->post(
    $epdqurl,
    [
'AMOUNT'    => $amount,
'CARDNO' => $cardno,
'CURRENCY' => 'USD',
'ECI' => '9',
'ED' => $expires,
'OPERATION' => 'SAL',
'ORDERID' => $transactionid,
'PSPID' => 'my_id',
'PSWD' => 'my_passwd',
'USERID' => 'my_userid'
    ],
);
open RES, ">test.out";
print RES $content;
close RES;



Portable air conditioning

Portable air conditioning

It sounds like just the thing. A small, battery-powered box that makes a room cold in just a few minutes.

 Except, it doesn't.

A real air conditioner is a heat pump. It pumps heat from one place to another. It works by compressing a fluid (which causes the fluid to get hot), it move the hot fluid to another place, then it uses convection to cool the hot fluid; so the heat is dissipated outside the room. Then the fluid is decompressed and that makes it get cold, and that cools the room. You can see the effect for yourself using a bicycle tyre pump. Refrigerators and freezers work the same way.

These portable units, don't have anywhere outside to dump the heat. Anyone with any sort of physics knowledge would know right away that a "portable air conditioner" cannot work, just as a perpetual motion machine can't work. Of course, most people have very little knowledge of physics.

So what do these units do?

If you blow air over water, the water gradually evaporates, and this cools the area by using the latent heat of vaporisation. Your sweat works the same way; the sweat evaporating from your skin, cools your skin. Not by much, but it does work.

So you could get the same effect by letting a fan blow over a basin of water ... and that's pretty much what these units do. Or they use ice, which means that they're piggybacking on your freezer, and your freezer will have to work harder to make all that ice.

If it comes with a hose that you poke though a window, then it could actually be a portable air conditioner, in which case it will cost around £500. If it's an evaporative cooler, then it'll be more like £30 (£15 to £20 if you get something from eBay), and if you pay much more than this, you're overpaying. The Beldray costs £20. The Cooledge costs £65, far too much, but most of these evaporative cooling units are grossly overpriced - and over-claiming.

There's a downside to evaporative cooling that no-one mentions. The air it blows out is a little bit cooler, but it is also a bit more humid. And that means that your own personal cooling system (your sweat) won't work as well as it does with dry air.

 Yes - evaporative cooling works. But don't expect it to do very much

The cost of living crisis

The cost of living crisis

Inflation has hit us. The consumer price index was 9.4% highr in June 2022 than a year ago. And there are lots of arguments about the cause - the Ukraine war has affected gas and oil prices, food costs more, we're seeing the delayed effect of the Covid crisis. Lots of explanations are being thrown around, but everyone seems to agree on one thing - the government must Do Something.

And so Some Things are being Done. None of them are effective.

There's a price cap on energy; specifically gas and electricity. In our house, we use very little gas - almost none, because our heating is done with a heat pump, which is driven by electricity. Also, we aren't on the "default tariff" - I had a big haggle with our vendors EDF to get the best price.

The price cap came in, in 2019. People thought it was a great idea, but experience tells us that it isn't as simple as that.

For any resource that isn't unlimited (economists call these scarce resources) there has to be a way to allocate them between buyers. The usual mechanism is price; a higher price causes a lower demand and (after a lag) a higher supply. And vice versa. If you try to control the price, and make it lower than it would be (a price cap) then demand is higher than it would be, and supply is lower.

The other mechanism is rationing. You tell people how much they can have. That worked in WW2 with food rationing, because it's possible to calculate how much food each person needs (about 2000 calories/day for women, 2500 for men). But how do you do it with electricity? How much electricity do you need? How do you ration electricity?

In April 2022, the price cap rose by 54%. It needed to go up, because global gas prices had gone up. You can tell a vendor "Buy your gas for £100 and sell it for £90) but they won't stay in business for long. A lot of energy vendors went out of business.

In October 2022, the price cap will rise by 70%. You see the problem? If your bill was £1000 last year, it went up to £1540 in April, and will go up to £2600 in October. The April rise was made more palatable by the fact that we don't need much home heating at that time of year, but the October rise will hit the winter of 2022/23.

People will be forced to choose between eating and heating, is the slogan I've heard. It's nonsense, of course. When I was a lad, if it got cold, you put on another sweater. We didn't have central heating - what we did have, is ice on the windows (single glazing) in the cold mornings.

So what can the government do? There's a variety of possibilities, but they all boil down to subsidising the cost of energy. But if you cut VAT on energy, you'll have to raise taxes somewhere else. Or borrow, and "borrow" implies "pay back later". And once you start subsidising the cost of energy, you won't be able to stop, because then that 70% price rise kicks in. The only hope is that energy costs fall in a few years, and I'm not expecting that to happen.

So everyone is telling the government "Do Something" because talk is cheap, and I've not seen anyone in government admit that "there isn't much we can do". They can do a bit of nibbling round the edges, but nothing substantial.

So the government will Do Something. And then act totally surprised when it has no effect.

This weird trick reverses diabetes

This weird trick reverses diabetes

How many times have I seen spam like this? A lot. But ...

In September 2021, I was diagnosed with diabetes. Using the finger prick test, I was coming in at 8 or 9 (normal is 4 to 7). And the HBa1C test was saying much the same (that's a blood test that is measurung the average over the last few months) . So, I changed my diet a bit (I never did take much sugar) and went onto a prescribed drug for it.

But I've been off the ddrug (Metformin) for months now, and I've not been watching my sugar intake. Yet by the prick test,  I've come down to 5 or 6, which is normal, and this is confirmed by my latest HBa1C test, which also came up normal. 

So what changed? Obviously the big change was the nine-hour operation in which they removed most of my liver and all of my gall bladder. 

So there you are. I wouldn't recommend this to anyone else, because the chopping of my liver was an anti-cancer measure, but it seems to have had the good side-effect of also removing my diabetes.

Diabetes

Diabetes

Last year, while they were analysing my blood, they also told me that I had diabetes. And a heart murmur.

I wasn't too bothered - I also had cancer, and ranked that way higher. I thought, I'll worry about the diabetes once the cancer is fixed.

But maybe I don't have diabetes. I got myself a test kit, and I've been testing every week or so. Normal is in the range 4 to 7, and at the end of 2021, I was reading 8 or 9. Which is diabetic, but only slightly so.

But now my readings have come down - maybe my liver is doing a better job than it did. My latest reading is 5.7 mmol/L, which is exactly in the middle of the normal range.

My blood pressure is also looking better, at 120 over 76. It had been in the range 130 to 150 at the end of 2021, and at the hospital, they even put me on blood pressure pills for a while. But normal blood pressure for an adult aged 20 to 40, is 95-135 over 60-80, so my blood is as good as it should be.

And my back is feeling a lot better now. I'm avoiding lifting heavy things because I don't want a recurrence, but now I can get into and out of bed without pain, and without using a stick.

Chemotherapy

Chemotherapy

Chemotherapy is used to kill cancer cells. I've heard various anecdotes about it, all the way from "no impact on how I feel" all the way up to "horrible". And since I am now a liver cancer survivor, I was concerned about the possibility of having to endure this.

Apparently, chemo is best done in the first 12 weeks after the operation, the idea being to destroy any residual cancel cells. It's the principle of "kick your opponent while he's down". Basically, you're taking a poison that will hurt the cancer cells more than the healthy cells. And that's why it can be horrible.

 Possible side effects include ...

  • feeling tired most of the time
  • feeling and being sick
  • hair loss
  • an increased risk of getting infections
  • a sore mouth
  • dry, sore or itchy skin
  • diarrhoea or constipation

 I got lucky. Because my cancer was detected VERY early (see previous post for why), the operation (which was a big one, lasting for nine hours and using five surgeons) removed all the cancer (along with most of my liver and my gall bladder). The post-operation histology confirmed that I was R0 (100% good).

So last week, I consulted with the oncologist, and he confirmed that I was all good, and didn't need chemotherapy. 

Hurrah!

Some time in the next several months, I'll be checked with an MRI scan, but that's a cake-walk.

New meter

New meter

In March 2021 I was asked by EDF, my electricity supplier, to read the meter. I tried, but the display had failed. I reported this back to them, and they said I needed a new meter.

Fair enough, I thought. But the next 15 months led to no new meter. Twice I had to cancel their proposed visit because I was in hospital, once they came with the Wrong Sort of Meter (two phase instead of three) and another time, the installed just didn't turn up.

But on 21 June, a man arrived with the right sort of meter.

He said it would take an hour of no electricity. I got ready for this by poering down all my computers, because my UPSes wouldn't run that long. THen he made the changeover, and I had power back - he took less than half an hour, because there were no complications.

But I haven't had free electricity for 15 months. With the faulty meter back at base, they'll try to get a reading from it - failing that they'll "estimate" my consumption.

So then I powered the computers back on. I expected at least one failure - that's what you get when a whole bunch of computers are powered off then on. But everything worked just fine!

Double VAT

Double VAT

Each quarter, I need to work out how much VAT to pay. It's a very complex calculation. I need to work out how much I've received from each EU country, and apply their particular VAT rate, and when all that's worked out, I need to visit the Irish tax website to report the numbers and pay the VAT owed.

Now that we've left the EU, do I still need to pay the EU this tax? I dn't know - I don't really understand how this ought to work.

For the UK, I need to total UK sales each day, list the VAT-registered purchases, report both numbers and pay VAT at 20% on the difference.

Obviously, I've automated this as much as I can. Each day when I do the billings, I append to a file totallog.txt what the sales are. This is done by the same routine that displays the summary totals.

Yesterday, I wasn't sure if I'd done that last part, so I had a look at totallog.txt to see if it was recorded there. What I saw was scary. What I saw was that every day, since May 3rd, the totals had been recorded twice.

I checked my program. It only recorded this once. How did it appear twice? I used Google to see if there were any clues there - no luck. I added some code to alert me if the output print was called more than once - it wasn't.

Eventually, I found the problem.  I opened the totallog.txt twice, once for appending the banked amounts, once for recording the eu and non-eu numbers. But I hadn't closed the file in between doing these, so with the file twice-opened, it was being appended to twice.

This mistake would have doubled my VAT bill. I'm glad I found it before it fed into my next quarter VAT returns.

Ancient computers

Ancient computers

It was 1984, and I was establishing myself as some sort of PC guru. I was writing for most of the PC magazines, and for the IBM PC User Group newsletter, and for the stockbroker that was my day job (my best article was "The bus has no driver", which countered the idea that economies are run by some elite person or group; in this case, the Saudi oil minister).

I realised that I was spending an hour commuting, each way, and those hours weren't productive. So when I saw the NEC PC-8201a, I thought, I can use this on the train.

It's small, A4 sized, and fitted nicely in my briefcase. It ran off four AA batteries (and I kept a spare set handy, It had 28kb of usable memory, which was enough for two articles.

It cost me £137, because I got it as a dealer from Pete and Pam (later P&P Distribution) and it was a fantastic bargain. The keyboard is a good, full-travel keyboard, the cursor control are the most logical I've ever seen. The only drawback was the screen, which was 40 columns wide and 8 deep, but I could live with that.

I'd spend the commute writing an article using the TEXT editor, download it to a PC using the TELCOM program. On the PC, I would spell-check it, reformat it to 78 columns, and print it out. Yes, in that days, even PC magazines didn't have computers, and needed printed text.

I still have that PC8201a. I got it out recently, and it didn't work. I opened up the battery case, and one of the traces was badly corroded, so I bypassed it with a bit of wire, and that made the battery case work. Then I struggled to get the NEC working, because I'd forgotten that there's an on/off switch on the side.

Now it works perfectly.

Bill Gates told me that the Basic for that computer was the last Basic that he wrote himself.

The next computer was the Sinclair Z88, which also ran off AA batteries, and had an 80 column screen. But that screen was hard to read, the keyboard was terrible, and I hardly used it. It didn't work when I tried it recently.

Then Amstrad brought out the PC100, another nice A4-sized computer using AA batteries. I got one for each of my daughters, but I don't think they ever used them. Now when I tested them, one worked perfectly, the other didn't.

Another nice buy was the Psion series 3a. This was a pocket sized computer that ran Dos. The other good thing about it is that it had a built-in database, and you could put your contact details into it, including phone number. Then you could phone the contact, and the Psion would emit the touch-tone signals to your phone, and you didn't need to dial. OK, not as slick as today's smartphones, but this was 35 years ago, and portable phones barely existed.

Another pocket size computer was the Toshiba Libretta. That came with Windows 95. I got it because I thought I'd use it for powerpoint presentations. In practice, it really wasn't very useful.

I also had another battery powered computer, but I don't remember the name, it wasn't useful at all, and it's probably buried somewhere ni a cardboard box. Its distinguishing feature was that it use 1 1.2 inch floppy disks.

If someone asked me to recommend a portable, battery-powered computer to be used as a writing system, I would definitely go for the NEC. They are still available on eBay, but at twice the price I paid.  runner up would be the Tandy 100, or TRS-80 100. Same machine, but an inferior keyboard layout.  The Olivetti M10 is the same. But they aren't commonly available.

Second would be the Amstrad, which you can get on eBay for £60 or so.

Disk failure

Disk failure

I got my first warning, when part of an important file, that was text-only, became corrupt and had binary stuff in it. I was able to replace the binary from a backup.

Then it happened again. And again. I'm so glad that I use a flat-file text-only database.

This is an important computer, it's the one I do billings from, and is therefore inside the innermost bastion of my firewall. That turned out to be a big problem later.

I used the SMART system, which tells me how many bad sectors there are on the drive, and it was large - and growing fast. This disk was on the verge of failing.

So, first I built a replacement computer. I used an Intel motherboard (I bought a job lot of these a few years ago, and they're great) with the CPU an E7500 dual processor running at 2.93 GHz. I put in 8gb of memory, and an 80gb 2.5 inch drive.

Next, to configure it, I used a 192.168.2.2 ip address, because that's in the range I use for "inside", the innermost bastion. That meant that I couldn't connect it to the usual 10.x.x.x range, it had to connect to the "inside". But the switch that is fed by the "inside" is way across the room, so I cleverly put a switch between the firewall "inside" and the switch across the room. Everything still worked. So I took a feed from the new switch.

That should work, right?

But it didn't. And I still don't know why.

I tried lots of things, such as replacing the new switch, and many others that didn't work.

Eventually, I did a "hail Mary" (an American football term for a desperation move) and slung a 10m cable from the old switch right across the room to the new server, and to my utter astonishment, it worked!

So I loaded up the new server, partly from the failing old one and partly from the backup, installed apache (latest version, and configuring that led to much grief).

Eventually, I got everything working, put the new server in the place where the failing server was, and everything is OK now.

Fetchmail follies


Fetchmail follies

First, I'll explain my email system. It's complicated.

To tell other computers where to send email for me, we use the DNS (Domain Name Service) system. In that, an MX (Mail eXchange) record tells other computers where to send my email. There are two main servers, mail2 and mail1. The MX record tell the priority. So, mail is sent to mail2, unless mail2 isn't working, in which case it goes to mail1. Both are Raspberry Pis, version 1, vintage 2012. I also retreive email from several AOL and Gmail accounts.

Mail1 gets spam, nearly everything. Because it shouldn't be used unless mail2 isn't working. I take advantage of this by setting up a bunch of MX records with even lower priority as spam traps.

But I don't want to visit both computers, so I set up fetchmail, to visit each in turn and use the IMAP protocol to collect unread mail and put it on my email reading computer., xantl. To read mail I use pine or alpine, a text-only reader. That means that I don't have to worry about unpleasant surprises that you can get in web-based readers.

When it gets to xantl, it passes through my mail spam filter,sorting the mail.

So what went wrong? Suddenly, fetchmail stopped fetching mail from mail2 and mail1. I hadn't made any recent changes. This happened a few weeks ago.

So I tried fetchmail -vvv (verbose) but that told me nothing useful.

I tried reinstalling fetchmail. i tried installing fetchmail on another computer. I tried reinstalling dovecot (the IMAP server) on the pis. nothing worked. I tried updating OpenSSL - no joy.

I tried using .forward on mail1, but that didn't help. and all this while, I was reading an dealing with emal on mail2 and mail1.

I tried changing the MX records to a different computer. No use.

Then I did what I should have done in the first place. Google is a great resource, but I also have a file where I keep a record of past problems and thier solitions, and I found this gem.

 To see what fetchmail is doing:
fetchmail -Nvvvd0 --nosyslog

So I did that, and it told that the problem was that fetchmail couldn't negotiate a secure channel with mail1. But I don't need a secure channel because the whole network is secured.


So I added 

 sslproto '' 

to the .fetchmailrc, telling fetchmail not to use secure sockets.

And everything worked!

I think this happened because fetchmail updated itself without telling me. The fact that a couple of weeks of Googling turned up nothing, makes me think that I'm the only person who has ever had this problem. There can't be many people using fetchmail release 6.4.23 to retreive mail from 10 year old Raspberry Pis.

Victory!

 Victory!




In July, I came up with the idea of using a more modern anticoagulant than
Warfarin, which I've been on for 25 years. Warfarin works, but I have to go to
the clinic every few weeks to get tested.

So they said yes, but we need to look at your blood. I gave a sample, And
nothing happened for a couple of months, but then I was contacted And was told
that I have markers. Meaning, a problem.

Part one

So I went to Wycombe hospital, and they gave me a thorough going over. I have
a minor blockage in one of my heart valves, but nothing to worry about. I have
diabetes; blood sugar normal range is 4-7, and mine comes in a 7-9, so only
slight.

And they did a CAT scan, and found a lump, in the duct between my liver and
gall bladder.

After that, everything happened very fast. I had an MRI scan, which confirmed
the lump, and I was told it's 95% likely to be cancer.

50 years ago none of this would have been possible; I had no symptoms, and
felt perfectly healthy. Then they did a PET scan; they put something slightly
radioactive into me, and scanned. A PET scan is a generic cancer detector. I
had to wait weeks for the result, but it came back clean, apart from the known
lump. I had to confess, I cried with joy when they told me this.

So I had a consultation with an oncology expert at Oxford Churchill hospital,
and he explained the options. But there was only one real option.

The liver is the only organ that can regenerate itself. And it comes in two
parts, a small part and a large part - the lump was near the large part. The
plan was to cut off that large part, and then the small part would grow.

But first, I needed three procedures; a procedure is a minor operation. The
first was to put a stent next to the lump, so that bile could flow freely to
the gall bladder. That happened in Oxford Radcliffe.

But it didn't work. They sedated me (meaning, I was asleep). I held a plastic
mouthpiece between my teeth, and they put a tube down my throat and navigated
it with xray assistance down to where it needed to be but they couldn't get it
in place. Worse - one of the risks of this prodecure is peritonitis, and I got
that. I vomited up the contents of my stomach, I had a terrible pain there,
and they shipped me back to Oxford Churchill.

Over the next several days, even the thought of food made me nauseous, and I
was in a lot of pain. They put me on Paracetamol, and a saline drip to keep me
hydrated, and the morphine, which was another drip that I pressed a button
when I needed more - which was often.

After several days, I was feeling a bit better, so they scheduled me for a
repeat of the procedure, except this time they went in through my side. That
worked, and now the bile drained through a tube, into a bag.

So, again some days to recover, and then we faced the next procedure. the idea
was to block the blood supply to the bad part of my liver, so it would start
to shrink, and the good part start to grow.

I was slightly sedated, and lay flat on my back for two hours, and my back
really doesn't like that. then I had to stay in that position for another two
hours, until eventually I could move and relieve the pain. That was 100%
successful. A few days later, they did the second part of that, which
consisted of blocking the outflow.

All this was to get me ready for the main event.

I got out of hospital 17 days after I went in. I still had the drain, but it
didn't drain externally.

While I was in hospital, I lost 18 pounds, mostly because of the peritonitis.
But I felt OK when I left, although with very little appetite.

That was November 22. I was told to get as fit as possible for the big event
in January.

Intermission

I spent the next two months eating as much as I could (which was not much, I
was still suffering a bit from the peritonitis) and exercising on the
stationary bike, 20 minutes per day. Then the date was set, 19th January.

Part two

I arrived at 7am January 19th as requested at Oxford Churchill, and the
anaesthetists went into action. They stuck things into me, and eventually
asked me what I was there for. "Full brain transplant" I said and they
laughed, but I didn't because I was suddenly unconscious.

The operation took nine hours and five surgeons - it's the biggest they do in
Churchill.

I woke up in purgatory. They call it the Intensive Care Unit. My mouth was as
dry as a desert, but when I called for the nurse, all I got was a wet sponge
to suck. I had to do this several times. Meanwhile, the noise level was high -
phone ringing, people chatting, large things being dragged noisily across the
floor.

On my second day there, they got me to walk round the ward, and that was good
enough for them to transfer me to the upper gastrointestinal (UGI) ward, the
same place I was in November. I was able to greet many of the nurses by name.
They put me in a room for four, and I settled down. I had been told that I'd
be there for 10-30 days, depending on complications.

At that point, I had two things in my side, giving me timed and measured doses
of painkiller, I had a catheter, a big cannula in the big wrist vein on my
left, another big cannula in my jugular on the right, and a small one in my
right arm. And so I rested.

The doctor team came round, and I was told that the operation as 100%
successful, and now they were analysing the histology. That took a few days
more, and also came back 100%. And at that point, I was no longer a person
with cancer, I am now a cancer survivor.

The worst parts of the ICU was when a nurse dropped the catheter bottle and it
went all over the floor - not my problem, but when it dropped, it jerked the
tube, and the sudden pain made me scream.

I also got into a big row about my eye drops. I take wo different kinds in my
left eye (glaucoma, but it's under control). First, the nurse claimed that I
only had one set of drops, then she claimed that I didn't take eye drops at
all, because it wasn't on her computer. So I pointed out that both of them was
on my printed list of medications that I had brought in, in the bag of
medications. Eventually, I stopped arguing. And they found my list of
medications, and agreed that I was right. And then they lost one of the two
bottles, and couldn't find it. That was fixed when they did a new prescription
for it.

I was so glad to get out of ICU!

After a couple of days in UGI, they took out the painkillers in my sides.
After a couple more days, they took out the catheter, which wasn't painful,
but the first time I tried to urinate (into a bottle) what came out was red.

I have to admit, that made me very worried. I called a nurse, she called a
doctor, and he spent quite a long time with me reassuring me that although it
was normal, it was quite common, and was caused by some minor damage inside,
and would clear up in a couple of days. And he was right. But when I looked at
what first came out into that bottle, it was natural to worry.

The next several days were spent mostly sleeping, plus a little bit of
exercise, and a little bit of eating. As soon as I felt a bit better, I got
someone to bring in a small side table, she set my laptop up for me, and I was
able to log in to my network, and everything was running smoothly.

But ... my left forearm became very sore - it was phlebitis, an inflammation
of the veins, brought on by all the needles. The nurse told me it would clear
up in a week, and it did.

I started doing ward rounds. I'd get up, put on a dressing gown, walk round
the rooms in the ward, and if a door was open and the patient was awake, I'd
stick my head in and ask "Fancy a chat?". This was usually well received, so
I'd come in (masked) and we'd sit and chat for a while, about why we were
here, and our professions, about our children, hobbies and that sort of thing.
I did this almost every day.

On February 8th, the consultant decided I was ready to go home, hurrah!

Day 673 of self-isolation - The post arrived!

The post arrived!

The post arrived today - in large numbers. We got 30 letters, that being the cumulative buildup pf post over the last month or so.

For example, one letter from Oxford Hospitals was dated 10th December, and asked me to come in for an XR chest examination, which I have not done because I didn't know about it. And there were some other letters from Oxford Hospitals about appointments that I have kept, because I told them that if they want me, the MUST email or text about the appointment.

There were numerous letters from the bank about routine matters, a couple of magazines, and a wifi antenna.

We've been having this problem with our post for some months now, and I've been told it's because of staffing problems. But I cannot imagine what kind of staffing problems would lead to letters arriving more than a month after dispatch.

We're going to make a formal complaint about this.

Day 672 of self-isolation - Screw removal

Screw removal

I ordered this a while ago, and it just arrived.  I have a multimeter which, as far as I know, is still working, it just needs a new battery. Unfortunately, one of the screws that needs to be removed to change the battery, won't budge. I tried WD40 and variations thereof, but no luck.

So I ordered a screw removal tool, which arrived today. It comes in various sizes for various screw sizes.

It's something for me to look forward to when I get back from Oxford.

Day 671 of self-isolation - Omicron falling.

Omicron falling.

The number of new cases each day has fallen below 100,000 from the peak of 200,000. It's looking good!

The pandemic isn't over, and in other countries, the numbers are horrendous and rising. But in Cool Britannia, things are looking up, at last.

Things can only get better!

Day 670 of self-isolation - Conspiracy!

Conspiracy!

Here's why I'm sceptical about theories that involve a large number of people keeping a secret.

It's because the more people are involved, the more likely the secret will get out.

Good examples are, the Downing Street parties. It's now looking like Number 10 was one long frolic. Another good example was the MP expenses scandal.

Things like this, do get public, and I'd guess it's via someone who realised that it was all so wrong, and felt that they had to blow the whistle.

Day 669 of self-isolation - Party

Party

It was May 20th. For me, it was day 65 of self isolation. Ladysolly and I would go on our daily exercise walk, avoiding anyone else who was along the route we took. We hadn't seen the kids for two months, except via Zoom. Groceries arrived by van, and we sprayed them with alcohol to disinfect. Anything else we ordered, would be left for three days before touching.

This was before the vaccines. This was the time of "Protect the NHS".

We were following the rules. Everyone was following the rules. Except ...

Meanwhile, Boris Johnson didn't think that the rules applied to him, and nor did 40 other people. So here's my question.

How on earth did he think that he'd get away with it?

And why is it, again and again, there's one rule for us and another rule for them?

Day 667 of self-isolation - VAT

VAT

I did the VAT today, and there's nothing to pay because they owe me. This happens because most of my sales are outside the UK, but all my purchases are inside UK. 

I have a date for my Big Day, it's the 19th January. The last three months have been leading up to, and getting ready for this. I've been doing 20 minute sessions on the stationary bike, and I've boosted my weight by 12 pounds, because for the first few days after the Big Day, I might not feel like eating. I don't know.

From the 14th, I go off Warfarin and onto an injected anti-coagulant Fragmin, and 24 hours before the operation, I skip the Fragmin. Nil by mouth for six hours before the op (to avoid stuff from my stomach coming up to my mouth and down into my lungs, a Bad Thing), and then up with the lark for the one hour drive to Oxford, so I can go under the knife at 7am.

My experiences in the last few months have always been that the event is nowhere near as bad as expected. For example, when I had the big nosebleed and I was told I needed to be cauterised, I was imagining red hot needles. The reality was a small dab of silver nitrate with a wooden paddle, and I was sent home an hour later. And when I had a catheter for the first time, I was expecting something truly awful as they insert a tube where I don't really want a tube to be inserted, but actually it was mildly uncomfortable and somewhat inconvenient, no worse than that.

After that, they'll keep me in for 10 days (if there are no complications). More if necessary, but I'm not expecting complications. I'll have a laptop with me, but I don't know at what point I'll feel up to using it.

However, just in case, I'm going to do the payroll and PAYE before I go in. I feel sure that HMRC won't mind the taxes being paid early.

Day 657 of self-isolation - VAT OSS

VAT OSS

VAT MOSS (VAT mini one stop shop) was the way that I used to pay VAT to EU countries; I used to use the UK system, but when we left the EU, I had to register with an EU country - I chose Ireland. They speak English.

Suddenly, VAT MOSS disappeared, and there's a new service called VAT OSS. (VAT One stop shop). It's exactly the same as VAT MOSS, but it's a different system. The things I fill in are the same.

It's almost as if they just changed the name, for no reason that I can imagine. I've been using the Irish system for a year now, and two of my returns are in the old VAT MOSS system, and two are in the new VAT OSS system.

I really hate it when things that I have to use, are changed for no good reason.

Oh well.

I filled in the data, and made the payment, and now I have to hope that the Irish tax people pay the various countries as they are supposed to, so that I don't get sudden allegations of non-payment, plus demands for money, from whichever EU country can't keep its paperwork straight.

I'm glad that I'm not shipping goods. The paperwork for that must be a nightmare now that we've left the EU.
