The forecast for today has already been revised to match the current reality of a fairly blue sky and sunshine. It then shows just sunny spells between 10am and 1pm, and then cloudy until 6pm. I expect this picture will be revised a lot before the day is over. The maximum temperature today should start at 3pm, and will only be 18° C (not 19° C as shown in the early forecast above). The BBC seem to think the sunny spells will actually last all day today, but agree on the temperature. Tomorrow may see 21° C, and there could be sunshine or sunny spells all day. The BBC agree with this forecast for tomorrow.

  Yesterday seemed to pass smoothly enough, but it was a day when the grey light outside dampened my enthusiasm to do anything, and that included my desire to semi fast through much of the day. I was still a bit restrained, but I ate more then intended. That is one of the problems of feeling cold and close to bored.

  In theory, after a really great night's sleep, where I got over my "eight hours" (and almost 10 hours !), I should have been raring to go, but a lot of yesterday involved being quite sedate. I spent a lot of the rest of my morning, after I finished writing, just laying on my bed reading, and I came close to snoozing several times. I don't think I actually snoozed, but I did lay there with my eyes closed for short periods.

  I can't really say the afternoon was a lot more dynamic. With grey light pouring through my bedroom window I felt cold, and I ended up running the heater on low almost, but not quite, non stop until mid afternoon. I was expecting to not need any ultra expensive heating this month, and maybe some of last month. Maybe it is my old bones feeling the cold more acutely than they used to.

  It was probably a bit after 1pm when I gave in and had a light lunch. It was just 4 chilli flavoured (allegedly) rice cakes with some beef and turkey salami slices on them. After that I must have been involved in some sort of fantasy dreaming. It concerned using my laptop away from home, and using mobile internet for it. I once did this using a "3" usb dongle plugged into my sadly damaged beyond repair, mini laptop.  I only did it a few times, but it was good to be able to do it.

  One "modern" possibility is to use a mobile phone in "tethered mode" where it converts the 3G/4G signal to WiFi that the laptop can connect to. Once upon a time this was frowned on by the mobile service providers, but many now allow it. I still have a working "3" sim card in my old firefox phone. I know, or knew, that I had something like £20 credit on that SIM card, but 3 would really like me to convert that into some sort of calling plan.

  I prefer to just keep it as it is, and make a call at least every 6 months to keep the card alive. Yesterday I tried using the Firefox phone in tethering mode, and connected my main mobile phone to it via WiFi, and allowed it to download a few tens of megabytes to see how well it worked. I could us it as a WiFi point for my laptop, but a better idea started to surface in my brain.

 "3" now have a subsidiary called "Smarty" working on almost the same principles as O2's giffgaff. A purely online service where you order a SIM card, and can buy service by the month. The interesting thing is that for the same price they seem to offer more data than giffgaff, and the explicitly allow tethering. I decided that maybe I should order a "Smarty" SIM card to do some experiments. I also decided I would leave they Firefox phone, and it's "3" SIM card alone, and use another old phone.

  One such phone that would be good is my old Wileyfox "Spark" phone. It was fairly good at the time, but one failure was that the battery started to bulge - which is a potentially dangerous thing because lithium batteries like this can burst into flames. The good thing is that the Wileyfox has a replaceable battery, and once upon a time Amazon used to list them, but never came up with the goods.

  I did an internet search and found several places with replacement batteries in stock, and they seemed fairly cheap. I ordered one for £18 including P&P. It is only 2/3rds the capacity of the old battery, but maybe that is a good idea because it seems they might have tried to pack more capacity in too small a space originally. That is why the old battery started swelling. It had swollen enough to start to crack the back of the phones case.

  I thought it looked like it was getting very critical, and decided to store it in a tin box in the garden until I can get it safely disposed of (or just force it to explode into flames for my own amusement !). The new battery, if the website I ordered it from can be believed, should be here in a few days. The next thing I needed was a new "Smarty" SIM card. It was actually quite late at night when I ordered it, but that could be here in a couple of days too. I then need to go online and activate the sim card, and buy about £8 of data as a trial, and remember to untick the auto renew box in case I don't want to use it next month.

  Yesterday was a weekday, and I watched my usual Star Treks around dinner time. I had a nice dinner of cheese salad, although I did over do the potato salad. I think I added too many tomatoes as well - tomatoes have a lot of natural sugar in them. Once I had watched Star Trek:Voyager I stopped watching TV for an hour until I turned on again for Have I Got News For You. That finished at 10pm and I thought it was time for bed.

  The only trouble was I got into bed, read for 10 minutes before turning off the light and tried to sleep. I quickly discovered that I was not sleepy at all. It was at 10.30pm that I got up again and ordered the Smarty SIM card. I then read some online technology news and stuff. I'm unsure when I went back to bed to try and sleep, but I have a feeling it was close to 1am before I actually fell asleep.

 Once asleep I seemed to sleep well. I seem to think I may have only woken once for a pee before 6am when I might have got up, but I managed to go back to sleep until 7.30am. What I do remember of my sleep was some vague details of a couple of dreams. One dream was about doing an illegal radio broadcast. It was, as expected, raided by the radio authorities. Although I was involved, I kept my distance, and appeared as an innocent party - even to the extent of casually chatting tom the authorities, and peering inside their van. Unknown to them was that I was wearing a watch which had a miniature TV in it, and I could see what was happening where the illegal transmitter was. I was happy to see "our side" removing the equipment before "they" got to it.

  The other dream I have a vague memory of was also about flaunting the law. We, whoever we were, owned a large round, brick built kiln that the authorities (whoever they were) wanted to use to burn some illegal drugs. It was a worthwhile money maker, and it had a big bonus. It was because of clean air regulations that the kiln had a sophisticated filtration system. Unbeknown to the authorities we could condense a valuable (illegal) derivative of the drug being burned. It was dream with almost no action that I can remember, and little more than a list of incomplete facts.

  I can't say I felt refreshed when I got up after my lay in this morning. In fact I felt like I had something akin to a very mild hangover - more groan than actual pain. The good thing was that my blood glucose, although rather higher than desired, or hoped for, was at least clear of the danger zone. It was 9.2mmol/l. Hopefully I can do better today, although I have started with a small bowl of Polish, beetroot flavoured instant noodles.

  The plan today is to probably to go out to take some pictures of trains - maybe at Clapham Junction station. The only trouble is that the weather seems to be turning a lot more cloudy than expected - just like yesterday did.Both the weather forecasters, in their latest revisions, say that 10am should feature full sunshine from a clear sky. Hmmm, we'll see ! The only thing maybe holding me back could be the state of my guts. I have a suspicion that yesterday's salad could cause some unwanted "digestive anomolies". My first visit to the toilet didn't produce much. Hopefully another visit will be more productive.
