Chirp ran fine on Linux when I needed it to program a UV-5R a year or two back - was provided in a flatpak then but looks like they use a Python wheel file now.

I'm sure I've read worse but one that stands out as making me question the time I put into reading it is Out of the Dark by David Weber. I go into it expecting a military sci fi, and for the vast majority of the book that's what you get - aliens invade Earth and plucky humans resist etc etc. The aliens however have more reserves and air superiority so are slowly winning as the end of the book approaches, at which point you expect the main characters to pull a rabbit out of the hat and do something different. Except that's not what happens.

spoilerWhat actually happens is that Count Dracula appears out of (almost) nowhere and flies with a bunch of vampires up to the alien spaceships to kill the aliens, winning the battle for Earth.

I was definitely not satisfied with this ending, even if there was some foreshadowing earlier in the book that made sense after knowing this was a possibility in this universe.

Far from the only one, I think there's plenty which could plausibly be a duck. It's just that most people seem to be going for one of these ducks:

Or one of these ducks:

instead of one of these ducks:

Self checkouts that just let you scan items without issue and accept payment are a nice enough idea for a bag or less of shopping, my problem with them is how they are implemented in reality (in Australia anyway). The first implementations I encountered I considered an useful addition but both the machines and the staffing changes due to them have steadily gone downhill in terms of user experience.

Instead of a quick painless experience you get a horribly touchy weight sensor which can't reliably handle particularly small items, particularly large items, or non-standard bags (and there are no longer standard bags due to plastic bag bans), a machine which demands assistant intervention at the slightest issue (and the assistants are understaffed so never arrive quickly), and when you finally get to payment it makes you click through an annoyingly slow interface to tell it you don't have a rewards card and don't care to donate to some charity before it will activate the card reader. To make things worse the manned checkouts are never staffed at a level - if any are even open - to cater for people with full trolleys so these end up clogging up the self checkouts (which have tiny bagging areas and are not intended to handle a trolley load) and making everything slower.

The icing on the cake is the self checkout treating you like a thief and throwing errors if the camera system thinks you didn't scan something in the trolley or letting off an alarm like you're trying to make off with something when you just want to buy a can of paint.

The bees would still overcome the wasp, assuming it's a large hive. The wasp will have practical limitations on the amount of ammunition for the weapon (also the question of whether it can reload before getting swarmed) and the ceramic armour won't help against the bees massing together to form a ball of bees around the wasp and overheating it until it dies.

Edit: Apparently it depends on the type of bees as to whether they do the heat ball of death thing, so your mileage may vary.

As in plasterboard sheets? I don't see why not if hand loading, plenty of vans will fit a 2400x1200 sheet (my Transporter fitted a bunch of plywood with room to spare). Loading one with a forklift is harder due to no side access long enough to fit 2400mm but that's a problem shared with tub back utes. If however your plasterboard pallet is side accessible a van with barn doors (like you'd buy if pallets were a priority) will allow you load it in fine.

The old boat also has a motor, note how it's still moving in the photo while the only person in it is in the back holding a tiller (and appears to be facing forwards).

The thinking involved in driving a manual is very minimal once you get used to it, so I reckon any safety issues caused by that would be outweighed by a reduction in the unfortunately common situation of unintended acceleration crashes. You are lot less likely to drive through the nearest wall (or kids) if your instinctual reaction to moving when you should not be is to also go for the clutch and cut power instead of just pressing harder on the wrong pedal.

They have a clutch, but once you're moving it is possible to shift a manual transmission without using the clutch. What you need to do is first take off the load currently passing through the box (if power is being transmitted either direction it holds the engagement dogs in place), so if accelerating you quickly let off the throttle and if decelerating you quickly tap the throttle. This lets you move into neutral, once in neutral you increase or decrease the engine revs to near (ideally exactly) what they would be in the gear you want to shift into at your current road speed, and holding those revs you can then shift smoothly into the new gear.

It is not something I would recommend unless in a jam with synchromesh transmissions (e.g. regular cars, light trucks) as most people aren't going to get it exactly right every time and will just burn out the synchros. If you're unfamiliar with the term these are the parts of the transmission that let you shift from one gear to another in one motion without having to stop in neutral, let the clutch out, and increase/decrease the engine revs to suit your desired gear before clutching in and shifting into it.

Clutchless shifting can and does work well in non-synchro transmissions (e.g. motorbikes, many heavy trucks) once you get the knack, as these transmissions are both more forgiving of not being exactly rev matched and will provide a strong auditory signal if you don't get it close enough (i.e. you'll know if you got it right or not so won't half arse it). Many motorbikes now actually automate this process with devices known as quickshifters - named so because even when doing it by hand clutchless shifts on a bike are noticeably faster than using the clutch.

I find it a bit amusing that the sepia toning effectively colourised the image.

The sun would be the most obvious choice for such a reference point, though it'd be amusing to make it Greenwich and therefore make everyone deal with Earth's rotation and orbit if they want extremely precise calculations (though I expect there wouldn't really be a practical difference on that scale).

The design of the front forks also assists with stability - having some rake and trail means the front wheel has a tendency to self centre (particularly at speed).
