Yep, you are correct, it is the answer. If it turned out to also be the address (whatever that means) that would be a fun coincidence, but probably not much more than that. Similarly, apparently 42 was chosen as in ASCII that would be the * character, aka a wildcard, aka the answer to life the universe and everything is whatever you want it to be. I'm not sure if Douglas Adams truly intended that or if it's just another nice coincidence, but overall what could be more Douglas Adams-esque than a large series of very interesting yet ultimately meaningless coincidences?

Something like this was done in the 80's; Have you ever played Sub Mission? If one of your characters dies and you aren't in practice mode, that character is permanently deleted from the disk. If you lose all of your characters there is nothing more to do except use the included form to order a new disk. The original disk was a booter so it wasn't something that could be backed up either (at least not by an average user). Overall the game sold poorly, and I'm guessing this well advertised feature played a big part in that.

That's my opinion as well, I thought we learned from the killer poke many years ago...

By accident. Happens to me all the time on my phone - sometimes I intend to be scrolling but accidentally tap my finger at just the wrong place and it's interpreted as a click and not scrolling, or because an ad is too close to something else and I fat finger the thing, and so on. I can be quite clumsy on a phone, overall.

Our local Ikea did exactly this; it is fantastic! As noted you get to park (and walk to the store) in the shade and the panels power the store (I'm not sure how much, I'm sure it varies with weather, time of year, etc...). There are electric vehicle charging spots as well, only a handful at the moment but I'm guessing expanding that if demand increases wouldn't be too difficult.

I'm not sure that approach is in any way unique to Facebook; sounds like large corporation playbook 101.

Additional tools to help:

If you want to try out more color blind color options, take a look at sites like Colorblind Web Page Filter. It will show you an approximation of what color blind people see.

Also try Google's own WAVE plugin for Chrome - it highlights lots of types of errors. Amusingly, as I tried it today, google.com is showing a number of errors so even Google isn't using their own tools!

There are lots of others - to your point, tools exist; lots of tools exist, and they are wonderful. Making accessible websites is complex, but also easier than it's been in the past

Crunchy is probably the wrong word but I didn't have a better one off the top of my head. I didn't intend to refer to artifacts such as those from aliasing but rather the thick, textured sound the YM2151 is capable of especially when compared to PSG style chips of the era. For the NES, it seems almost nothing but an actual NES gets it 100% right; not just emulators, but many clones of the system sound a bit off too.

All arcade manufacturers reused designs a lot; designing every game 100% from the ground up wasn't practical when you had a perfectly working system board that would work quite well for multiple games. Even when a new system was designed, some components would still be reused. In the case of Marble Madness a Yamaha YM2151 FM synthesizer chip (along with Atari's venerable POKEY chip) created the sounds so you'll get that nice, distinctive, rich, crunchy FM sound found not just from multiple Atari games but from other manufacturers as well (Yamaha FM chips were quite popular; other companies that used it or a very similar one include (and are not limited to) Konami, Capcom, Williams, and Namco).

seems like they finally sold that part of the company off last year though...

It's not just Google; Microsoft has been changing Windows constantly, and it's definitely not getting better. I think Apple is a little better in this regard, but they aren't immune either; iOS and MacOS changes still creep in with seemingly little reason for them other than to make the new version look new.

My guess is it's a way (and a rather dishonest one at that) to push/advertise this feature: Microsoft Adds Buy Now, Pay Later Financing Option To Edge -- And Everyone Hates It

It can produce normal apostrophes, but it's now turned off by default. The funky apostrophe is due to the "smart punctuation" feature which is using a left or right apostrophe instead of a simple vertical apostrophe. Like most things labelled "smart", it's not. This can be turned off in settings.

Even if it doesn't directly support trackballs, there's a workaround if you don't mind a little crafting. Companies like Groovy Game Gear and Ultimarc (probably others too) sell trackballs for use in arcade cabinets and similar MAME projects. Essentially they are visible to Windows as a USB mouse, and work rather well with MAME trackball games. Would probably work fine for this one too.
