  1. Nope. If you can afford one, I recommend that you get a portable air conditioning unit. You can one for 200 quid that will chill one room: https://www.amazon.co.uk/dp/B07D394VPK/ref=twister_B07D37V8G9?_encoding=UTF8&psc=1 With a portable unit, there are no installation costs - plug in to a mains socket and put the exhaust hose out of a window. When it's not required, just wheel it in to the spare room where it will sit quite happily, waiting for the next heatwave. I bought a similar unit about 10 years ago and I reckon I have used it about 100 times (so 2 quid per night + electricity), but it has been worth every single penny. The only down side is that they are noisy when running, so I run it for about an hour before going to bed, during which time it takes a room at 28C down to about 21C, and reduces the humidity as well. It is a wonderful feeling to go from a hot, humid house, to a cool, dry bedroom, and then get a good night's sleep. If the room heats up again during the night to the point it wakes you up, put it on again for a quick blast to cool it down again.
  2. Big disclaimer: I'm a fan of space exploration. If you're not, then I doubt you'll find this interesting. I've just watched the Blu-Ray of this on my plasma TV and in surround sound: https://www.apollo11movie.co.uk/home/ It is absolutely brilliant. It is just archival footage (with a few simple and brief animations) combined with some music, a load of mission control audio and an occasional dash of Walter Cronkite's commentary. The launch is fucking amazing. If it comes out in 4K, I'm going to buy a 4K TV just to watch it.
  3. For a start, the original statement is incorrect. When multiplying or dividing two negative numbers (as long as they are real*) the result is always a positive number, but not necessarily when adding or subtracting two negative numbers. For example: Addition of two negative numbers giving a negative result: (-4) + (-3) = (-7) Subtraction of two negative numbers giving a negative result: (-4) - (-3) = (-1). This is (sort of) how it works for multiplication and division: Consider the multiplication of a number by -1. This is the same as subtracting the number from zero. e.g. Instead of adding (credit) 2 pounds to an empty bank account, you take (debit) 2 pounds out. This is the equivalent of flipping the sign from positive to negative. Multiply a number by -1 twice and you end up with the original number as the sign is flipped twice and returns to it's orginal state (i.e. the second flip cancels out the first). Any multiplication by a negative number can be converted to a multiplication of a positive number, and multiplying that result by -1. We can also change the division of a negative number to the division of a positive number followed by the multiplication of -1. e.g.: 4 divided by -2 can be changed to (4 divided by 2) x -1. Therefore, division (with regards to flipping the sign) behaves in the same manner as multiplication. *Someone said don't mention imaginary numbers. I say, why not! They can be "complex", but they're not complicated! As well as real numbers, there are "imaginary" numbers. These are wacky! They involve multiples of the square root of -1, known as "i" (or "j" if you're an engineer). Yes, it really is that bizarre (and simple). With imaginary numbers, you can multiply two negative numbers and get a negative number! e.g.: Multiply (-3 x i) by (-2 x i) and you get 6 x (i x i), which, as i x i = -1, gives -6! Complex numbers are imaginary numbers with real numbers added to them i.e. 3i + 2. These are used for many things, but possibly the most widely known is to generate images of the Mandlebrot set (https://en.wikipedia.org/wiki/Mandelbrot_set). I remember when I wrote my first Mandlebrot Set Generator program in BASIC in about 1992. It freaked me out the first time my program worked as I knew there was no image data in the program, it was like it just appeared out of nowhere! One final point I would like to make: Nobody should ever be scared of maths. If you feel intimidated by maths, or think "I just can't do maths": Don't. Take it as slowly as you need to, and never be afraid to ask for help if you need it. You might be amazed by what you can learn. P.S. Have you finished your whisky? My ciders were very nice (and are my excuse if this is full of errors).

  5. According to this newspaper, Hitler runs in a kebab shop in Hull. :-) https://mobile.twitter.com/thesundaysport/status/1038517453427552262
  6. I think you've slightly missed my point due to me not being specific enough. I wasn't just referring to physical assets that are primarily a store of wealth (perecious metals, hard cash, works of art etc.), but also to useful physical assets such as cars, and in particular, property. That's what I find truly scary.
  7. I think this could well be the case. I've just watched last week's edition of This Week, which, during the end credits, showed parts of an old interview with John Bercow. I'm guessing it was recorded not long after he became an MP in 1997. Here's my attempt at a transcript of the clips of the interview as shown. Make up your own mind how revlevant it is. Please be aware of the edits - the So-Called BBC could have swapped quotes around and missed out other significant sentences. Note: "Narayan" by The Prodigy is played quietly in the background throughout. I thought this was relevant as the first two lines are "If you believe, that Westminster, is falling down, on everyone" - except I've been wrong about that for 22 years! The lyrics actually are "If you believe, the western sun, is falling down, on everyone". I wonder if the person that selected that track has the same cloth ears as me? Voice over: "Good afternoon to John Bercow MP. He's a Tory Euro-Sceptic, and proud of it." John Bercow: "Make no mistake, if we join the single currency, it will almost certainly fail economically." [Edit] "The effect of that would be to damage employment, and growth, and prosperity in Britain." [Edit] "It is absolute nonsense, for Britain to sign up to a policy, made by people in Frankfurt who we do not elect, and who we cannot remove." [Edit] Voice over: "Fair enough. By the way John, enjoyed the Titanic analogy a moment ago. Got any more, about say, interest rates?" [Edit] John Bercow: "A one interest rate policy, for the whole of Europe is like a golfer, going out on to the golf course, with one club." [Edit] "I am not interested, in signing up to a policy, that puts Europe before Britain." [Edit] "People who live in Lewisham, are not going to go to work in Luxembourg." [Edit] "That means a single government, and a single state."
  8. I read almost exclusively non-fiction, mainly accounts of sports, science or space exploration. The one book that made me re-think how the world works was "No One Would Listen" by Harry Markopolos. It is the story of how the Bernie Madoff Ponzi scheme was uncovered. Markopolos was tasked by his bosses to work out how Madoff was getting such high returns so that they could copy him. Initially, Markopolos couldn't understand how Madoff could be making so much money, and concluded that Madoff's business was fraudulent. When Markopolos eventually uncovered proof, no one would believe him as Madoff was so well respected. It took about another 10 years for Madoff's scheme to collapse. Now for the scary part. This book made me realise that the ownership of all assets is just an opinion, usually based on a database of some sort. Whilst an asset may be physical, the record of the ownership of that asset is just information. If the relevant authorities conclude that information is wrong, you have nothing.

    If you want go for a refurbished machine, but don't trust the operating system on it (i.e. full of malware or it's Windows 10, which is full of malware anyway) then if you can't get a Windows 7 licence, you could try Chalet OS. I've had a play with it on an old laptop, and it is pretty similar to Windows 7. Within an hour of starting the installation process, I was on the net and playing videos in VLC. I've had a go a linux a few years before, and always given up in frustration, but Chalet OS was fine. Here's a review of it: https://www.linux.com/learn/chaletos-linux-those-who-miss-windows-7
  11. I think you'll find it was a tin of pineapple rings, not chunks.
  12. This is not an attack but an observation, so whilst you may be offended by my comment, please understand that no offence was intended: I don't think that any of my friends (or family) would ever consider entering a relationship with someone who said this seriously.
  13. I'm Scottish but I can't stand whisky. I've been given a glass of some stuff that apparently cost a few hundred quid a bottle and I thought it tasted like a mixture of cigarette ash, vinegar and bleach. It's been a few years since I've tried any whisky and as I've always tried to drink it neat, perhaps I was doing it wrong and maybe he's on to something? I do find those videos quite entertaining though
