UK 240V with 13A sockets, 3120W. Sounds like Lidl are rounding up.

Capsaicin isn’t just effective on mammals, it also has an effect on some fungi and insects, though mostly through metabolic disruption.
But for those of us who need that access we can disable it, with a bit of a dance to make it hard for people who _don't_ need it.
“On accident” is American English, as a British English speaker I’d consider it a grammatical mistake. The same goes with “I forgot it at home” and similar constructs. However they’re correct American English.
The extra fuel burn is due to the drag from pushing a non-working engine through the air, and from the rudder deflection to counteract the unequal thrust. It’s less of an issue on a four engine aircraft with a single engine out as they can increase thrust on the remaining engine on the side with the engine out.
Extra fuel burn is also required because a twin engine aircraft with an engine out can’t maintain the normal cruising altitude, and the higher you are the more efficient the engines are.
Thrust can’t be reduced much to save fuel because the speed margins at altitude are quite narrow - if they reduce thrust and therefore airspeed they’ll descend.
In the SQL spec by default unique indexes consider nulls distinct because you’re adding tuple to the relation, and this is done by equality.
When doing a select distinct or group by you’re not doing a boolean grouping, you’re doing a set projection. NULLs are considered part of the set of “unknown values”, so NULLs are grouped together but they’re still not equal to each other.
The behaviour is mathematically well defined, but it doesn’t match boolean logic.
I’ve been dealing with databases for well over 20 years now and I can only think of a couple of times when this behaviour wasn’t wanted, so I think it’s the right choice.
Rosin is also used on violin bows to increase friction, and it’s the white powder you’ll see gymnasts and baseball pitchers apply to their hands to improve grip.
Rosin vapour is a lung irritant, so avoid breathing it by using a fume extractor, and for some people it can cause contact dermatitis.
Yes it’s horribly sticky, that’s the worst part about it really. Isopropyl alcohol will dissolve it.
If you’re applying fluxed solder directly there’s not much point applying separate flux to clean metal. Of course the flux will boil off pretty quickly so you need to use extra if you’re doing something where the solder wire doesn’t directly touch the components, or if the metal is old or previously soldered.
The only advantage to non-fluxed solder for most hobbyists is being able to choose your flux, but for most of us rosin is fine and fairly non-toxic.
So NULLs are not comparable but they are part of the same set.
Metallic lead is dangerous if inhaled or ingested, but not a big concern for momentary contact with your skin as metal, especially given most modern solder is only 40% lead.
Your body will remove a small amount of lead, so hobby soldering is unlikely to cause long term problems.
I use Канифоль/rosin flux as well and use a fume extractor. Rosin flux is the most common for flux-cored solder in my experience.
But a few times a year is unlikely to be an issue, soldering health effects are in people who do it for work.
I mentioned it for completeness because someone else would if I didn’t.
Other technologies like glues and crimping have their uses but are less reliable, higher resistance, or difficult to automate.
This may change but there’s little demand. Glues have lower conductivity and are harder to remove, mechanical connectors are bulky and not as strong.
Lead does bioaccumulate so continual exposure to low levels is dangerous, but unless you’re soldering all day every day it’s not likely to be dangerous.
If you’re a factory and have multiple wave soldering baths operating it’s a different story.
However, lead free tin-silver-copper (SAC) solder is fairly easy to work with. You need a hotter soldering iron at around 300°C, and if soldering PCBs preheating the board to 80-100°C may be needed for good results. It may also take a bit longer for the solder to propagate flow and wet, since the surface needs to be hotter.
If you’re using additional flux or non-fluxed solder you’ll need to check it for compatibility, that should be on the data sheet. Most fluxes are fine, but I’ve seen a couple that say not to use with some lead free solder formulations.
The main downside to SAC lead free solder is the higher temperature required which can overheat some components, particularly capacitors and ICs in my experience. It’s a case of being careful to keep the heat duration as short as possible.
Personally I went back to lead solder and manage my exposure with ventilation and HEPA filters.
Just because the younger generation are doing things differently it doesn’t make them wrong, in my generation it was sending text messages that was wrong because we weren’t talking on the phone. Before that it was talking on the phone rather than going to people’s houses.
I’ll also add what my psychologist told me.
Social skills aren’t innate in humans, we have to be taught them. Smaller family sizes and greater distances from extended family mean these aren’t taught by older siblings/cousins/etc like the used to and parents aren’t filling the gap, which means standards of social interaction are changing much more rapidly.
Honey’s advertising message was “never search for a coupon again” and “we’ll ensure you always have the best discount possible”. However in reality a merchant could sign up as a Honey partner and for a mere 3-5% commission they’d let you set the coupons that Honey would show.
So for example if your business gave a 20% promotional coupon to a small community, you could set Honey to ignore it and only show a 5% coupon in the coupon search. People with the 20% coupon will still get to use it, but Honey will never supply it.
So not only was Honey removing affiliate revenue from the people promoting it, it wasn’t giving the people using it the best deal that it promised.
However we have a single payer health system for the most part (you can get medications that aren’t through the system, but you pay full non-US market price), so the big stick is “well we’ll buy from someone else”, easier said than done of course but it seems to work.
Our medical regulator (different body to the purchaser) doesn’t do inspections overseas but does random tests on the products imported to check the quality.
Of course I have strategies to manage this, and medication helps somewhat. But if I set a deadline for myself I’m never going to keep it.
In addition to flavour compounds from the nectar, honey contains trace amino acids that cause it to slowly undergo the malliard reaction at room temperature, resulting in a caramel undertone that increases as the honey ages.
The flavour also strongly depends on the nectar, with some being very subtle and resulting in a very syrup-like honey, and others being extremely strong.
Other than flavour, and some anti-microbial properties, it has the same dietary properties as sugar syrup.
It also depends on the sort of processing done. Commercial honey is pasturised, but local suppliers might not.
Of course they’ll likely be creamed honey rather than pourable, but that’s just a preference.
Here in New Zealand there are maximum limits on the number of coins you can use so paying your tax with a truckload of 10¢ coins is illegal, but if you use $100 notes you can use as many as you like.
