  1. Just a heads up on the above issue, I went to post an article and the same happened to me but it was a long script, so, I shortened the script dpwn and added a link for the full script and it worked fine.
  2. That's my flu jab letter from the NHS just arrived and they had booked me into the same place they had booked the wife, 10 odd miles away and a 40-minute bus journey, no way I will be going there so I rung the clinic and cancelled the appointment and told them I was booked into the local pharmacy (and the wife) which was a 5-minute journey up the road.
  3. Think it might be a wee glitch, Luke, this laptop suddenly went on a slow loading episode so I just logged out and cleared my cache etc and logged back in, it seems to be ok now. I also noticed a few times when I have logged in and I viewed the ' Users on line' my name did not appear as ' On Line'.
  4. A winter’s tale (in the Kuiper belt) As Pluto’s orbit takes it further from the Sun, scientists get an opportunity to study how the dwarf planet stores heat. Winter is coming on Pluto. And it is a winter, scientists say, unlike anything imaginable on Earth, a winter in which the dwarf planet’s entire atmosphere is expected to freeze out as frost, leaving it nearly as airless at the Moon. Not that Pluto has ever had a thick atmosphere. Its current surface pressure is only a bit more than 0.001% that of Earth’s, and there are indications that this is the densest it ever gets. What’s surprising, says Eliot Young, a planetary scientist at the Southwest Research Institute, Boulder, Colorado, is that Pluto’s nitrogen atmosphere is as actually as dense as it is. Since 1988, when its density was first measured by observing the way it dimmed starlight when Pluto passed in front of a star, it’s actually increased by a factor of nearly three, something that can only occur if frost has been steadily sublimating from the surface during the intervening years. That would make sense if Pluto’s elliptical orbit was carrying it closer to the Sun. But it reached its closest approach in 1989 and has since moved 10% farther out, which, given the way solar heating works, means it is receiving only 77.8% as much energy from the Sun now, as then. “It’s a surprise that Pluto’s atmosphere is as big as it is and has been growing for 30 years,” Young said on Monday at a virtual meeting of the American Astronomical Society’s Division for Planetary Sciences. Now, however, it appears that this trend is on the cusp of reversing itself. _____________________________________________________________________ Read more: In the Kuiper Belt, a baffling lack of small craters _______________________________________________________________________ In August 2018, astronomers realised that Pluto was about to pass in front of a fairly bright star – an occasional event which, like the first one studied in 1988, allows them to probe the density of its atmosphere by watching how the starlight dims before it winks out… and how it brightens as Pluto moves out of the way. Better yet, this was going to be observable along a broad arc running across much of the US from Texas to Virginia – making it easy for Young’s team to deploy a dozen or so portable telescopes (16- to 20-inch apertures) along that arc in the hope of observing the two-minute event from as many cloud-free locations as possible. Luck was on their side, and they not only had clear skies, but even managed to predict the centerline of the arc so well that one telescope wound up only six kilometres from the perfect location. “We’ve never gotten that close to the centreline before,” Young says. “It wasn’t long ago where we’d have been happy to have gotten within 100 kilometres.” When NASA’s New Horizons spacecraft flew by Pluto in 2015, it measured the surface pressure of Pluto’s atmosphere at 11.5 microbars. (One microbar is one millionth the pressure of Earth’s atmosphere). If Pluto’s atmosphere had continued thickening at the rate seen in prior studies, Young says, his team would have expected to see a pressure of 14.4 microbars. But instead, they got 11.4 microbars, “basically the same thing New Horizons saw.” That may not sound like the onset of winter, but it’s definitely the beginning of fall. And once Pluto’s temperature starts to drop, Young says, its atmosphere is going to freeze out very quickly, with half of it freezing out with each 1.5°C drop in surface temperature. The reason the big freeze has been delayed this long, he adds, is similar to the reason why beach sand continues to heat up after high noon, or why the hottest time of year isn’t the summer solstice, but later on. Even though the solar intensity is waning, heat has penetrated below ground, from where it is slow to dissipate. “It keeps the surface warm,” he says. Studying the timing of this process as Pluto continues to move outward from the Sun (eventually to about 1.67 times the distance it was in 1989) will teach scientists a lot about how its subsurface retains heat, Young says, including such factors as how porous its materials might be. “It’s a chance to look below the surface and see how heat is stored,” he says.
  5. Just scroll down with the new emojis amd you will find them at the bottom instead of the top.
  6. Puddin been fed and now tucked in for a snoozzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
  7. Bloody hell, unusual for me, I told the wife she can put the central heating on if she wants...it's a bit nippy...never seen her move so fast and switch it on, it's pissing down outside.

    Lol, so is the wife, she is going bonkers " Is it back on yet..." " NO.."
  10. Thank fuck Facebook is down, the wife can't get into her bloody Farmville and I can't hear all of them fucking animals noises, neighing, blaaaing, moooing & pigs snorting...bliss.
  11. I know the wife's niece has always suffered from panic attacks and I never knew what it was all about until something happened about 15 years ago that led to me having a panic attack so my doc told me. I had just been made redundant from a job for the second time in my life and I was way down in the dumps, I got up early one morning to nip up the shop and when I made my way back to our top floor flat at the time the stair lighting suddenly switched off when I was trying to put the key in the front flat door. Well, I panicked and I couldn't get my breathing under control and I was out of breath trying to open the front door so I started to bang at the door and calling for the wife when she came and let me in I just staggered to the lounge trying to breathe and she burst out crying thinking I was having a heart attack. I managed to calm her down and calm myself down and I managed to call the night duty doc up who came around, she gave me some oxygen and then when I told her what had happened and being short of breath that's when she told me that I had experienced a panic attack and advised me to see my local doc as she thought I might have had an asthma attack too. I visited our docs who said I had asthma and also COPD and the shortness of breath I had because of the asthma gave me a panic attack and now I am on pumps (asthma & COPD) for life, and even now if I get worked up about something I will get a shortness of breath and I make sure I take my pumps to calm down.
  12. Got both, don't know about the HD bit but I will go by what nudge said, out of the 2 they are both the same really but getting onto Netflix is a lot quicker as that is in our Virgin Package Deal, with Amazon I use a Fire Stick so it takes a couple of minutes longer and the info on the films is not as good as Netflix.

    Lottery

    The wife said "Weird bloody numbers on the lottery last night, 32, 35, 36, 37, 40, 51 & bonus ball 43... I guess we didn't win anything?", "WRONG darling, we won £37 with a lucky dip..." that will be spent on the grandsons guaranteed knowing the wife.
