As soon as I started kleuterschool, as they did it right.

Every year, I set myself a new years challenge. They do not have to be serious, or start on Jan 1. I don't tell people what they are until they notice. Some have lasted decades. Giving up chocolate was because of an alergy to it.

I defer to the greater knowledge of Mick Jagger and Marriane Faithfully when it comes to chocolate. Not touched the stuff since June, 1986.

When higher power LEDs started to become a 'thing', I, like many people that had had their cataracts replaced with shiny new acrylic lenses, found them quite painful. Now they put better coatings/filters/diffusers on them, they are not quite so bad. Been told the earlier ones were 'more blue lights' and considering most misted up lenses are caused by UV light, this group of people could be more susceptible to that part of the spectrum. The headaches brought on by excess brightness is because the iris is forced to contract more than is natural, and then we screw our eyelids up, in the best Wilfred Pickles impression we can. So muscle pain, not magic piskeys caused by EMR at special frequencies in the air. Over at the other place, there is an architect who claims, his wife claims, that she knows when he has the WiFi on in their office as she gets a headache. Having spent a couple of hours listening to him, and 3 con men, trying to convince themselves that both thier bio digestor and hydrogen fuel cell broke the known laws of physics, and PV could never pay back the embodied energy involved in its manufacture, I had a headache. Humans have always been bathed in EMFs, even when we sat around the campfire.

Within reach.

Welcome Seems about the right balance. If you spend half an hour a day, and it is productive, then you are way ahead of others. You could swap out the gin for Blue Sparkle.

Worms not slugs Hungry worms will risk being hurt if it helps them reach a meal When enticed by the smell of buttered popcorn, food-deprived nematodes are more willing to cross a toxic copper barrier to reach the smell of a snack compared to their well-fed counterparts LIFE 5 May 2022 By Corryn Wetzel Nematodes are willing to take risks to follow the smell of a snack STEVE GSCHMEISSNER/SCIENCE PHOTO LIBRARY Hungry worms are more willing than satiated worms to cross a toxic barrier of copper to reach the scent of a meal. While there is plenty of anecdotal evidence that hunger can make animals act impulsively, less is known about how hunger is signalled in the brain and how that signal shapes choices. To better understand how hunger changes behaviour, Sreekanth Chalasani at the Salk Institute in California and his team turned to transparent roundworms called nematodes. They aimed to answer three key questions: how does hunger affect what is happening in the worm’s body, how is that change relayed to the brain and how does that ultimately shape choices? The researchers placed around 60 nematodes (Caenorhabditis elegans) on one side of a barrier made of copper, which is toxic to them, with the smell of buttered popcorn wafting over from the other side. Half of the worms hadn’t eaten for 3 hours, while the others had eaten a recent meal. Chalasani and his colleagues found that around 80 per cent of the hungry worms crossed the repellent copper to reach the food compared with around 20 per cent of their well-fed counterparts. When the hungry worms were fed, they reverted to the less-risky behaviour of satiated worms. “If [the worm] is food deprived, it thinks, ‘I’m going to take that risk, because I’m getting hungrier, and so I have to make an effort to cross that barrier’,” says Chalasani. After demonstrating that the starved worms take bold action to reach the smell of food, Chalasani wanted to find out what mechanism was triggering the hunger signal to the brain. A genetic and imaging analysis pointed to certain proteins in the worms’ intestinal cells that may tell the brain that the gut needs food. The researchers also identified a receptor in the brain that they suspect is picking up the signal. “The intestine then tells the brain, and the brain then changes behaviour,” says Chalasani. “That was a little bit surprising. We didn’t expect that the worm would have this level of sophistication.” The work could help explain why some people behave irrationally when they have skipped a meal, as underlying biological patterns in nematodes often translate to humans. But Chalasani notes that being “hangry” doesn’t excuse poor behaviour. “I could be hungry and still not show it because [unlike a worm] my brain has the sophistication to suppress some of those feelings.” Journal reference: PLOS Genetics, DOI: 10.1371/journal.pgen.1010178

My Father was an observer/navigator/wireless operator in Mosquitoes during WW2. He never lost the ability to use Morse. Guess after 6 years of it being very important it kind of sinks in. He was in the Reserves till the early 1970s.

Yes. If you have LED lighting, you may find some of the drivers a bit 'buzzy'.

Bit in last week's comic about if they are hungry, they will cross a copper barrier. Plug it into the mains, will stop the scrumpers.

In my limited experience, yes. Trouble is, it can move too much.

Is it plasterboard with insulation attached to it. Nearly every place I have seen that used, seen the screw heads pop.

Doing a similar 'spring clean' at the moment. Don't think I can post up what I have found that belongs to my old partner. May forward a picture to @pocster, then deny all knowledge (shall strip out geolocation data and replace it with his position).

That late in life. I have an out of date Part P. I shall a play when I have more time, never used the ADC on the 8266s.

......... Quite interested in this. Can you post up a diagram. I have some ESP8266 that I can play with.

Why I pay them so little, I like the noise.

Large scale compressed air storage (often in old salt mines) is not new, been around a while. Competitive on price and tested.

That neighbour you dislike. As a peace offering, let them park their car in your drive for a few months. I hope that wall that your better half wants changed is the one facing the bottom of the drive. Or just pressure wash it.

Lots of people. They prefer to call them 'the conservatory'.

Weather and time.

Bit more complicated than that because of the effective area lost where the motor spindle attaches to the fan. Small fans loose a greater fraction of area. But that lost area also has less of an overall impact on airflow. Then, approaching the blade tips, 'apparent wind' effects can dominate, why blades are twisted and have different areas/profiles. This can also affect the air vortices after the blade, too low a pressure and the airspeed speed stalls. Small fans i.e. computer cooling fans, are basically blunt tools to shift as much air as possible, within a fixed form factor i.e. fit on the CPU and within the case. This is why liquid cooled systems are now used. My old Acer had a phase change system that allowed for a very low profile, but a larger fan fitted in a more convenient place (I cooked the CPU as I never cleaned the fan out). Quite simply, when it comes to shifting air, fan diameter, and therefor surface area, is the governing factor.

High Wycombe's old maternity unit was called The Shrubbery.

I think the fast response is a bit of a myth. Probably takes a few seconds for systems to adjust and synchronise. Emergency generation (usually diesel) responds fast, as do hot spinning reserves (why they are hot). I often think that people think that the advances in IT system that were seen between 1985 and 2005 can be directly implement into grid scale, bulk generation. There is no 'Moore's Law'.
