Mark Sheppard was so young!

Depends on the type of ad. The new ones that YouTube injects into the video stream would not be blockable. Everything else is blocked just fine.

same amount of effort

Physical effort, yes. Cognitive effort, no.

• Intros on a serial show are expected, and in some cases change subtly from one episode to another to provide additional entertainment value (eg the Simpsons intro). In other cases a change of intro sets the setting for the episode (eg Star Trek: Enterprise's Storm Front episodes).
• YouTube ads are not related to the show, provide no contextual value, and in the case of interstitial ads are not even at a predictable time. They also tend to be inanely repetitive, showing the same ad over and over in consecutive videos. Contrast those to eg halftime ads at the Superbowl broadcasts, which have predictable timing, variety, and have a history of being (or trying to be) entertaining.

Hah, I tend to make huge minecart networks, so I used the gold for the tracks. I know I could technically duplicate them, but that just feels too cheaty to me.

And again, I know some other crops can be generated faster, but pumpkins and melons are for me the sweet spot for density. With 4 farmers I can trade 3 stacks of melons and 5 stacks of pumpkins for enough emeralds to get what I need in a day. With paper that'd be 6 stacks of paper per librarian and I'd need 6 librarians to get the same amount of emeralds, so 36 stacks total. I'd rather not click back and forth all the time between my chests and the villagers to do my trading.

Since the mob is immune to damage as long as the heart is safe it could also work as bait for mobs that are hostile to it.

Live action: Major League 2 had a streak of getting played on TV, so it's probably the one I've seen bits of the most, followed by Rudy for the same reason.

Animated: Cars.

Farmers are IMO much better for getting emeralds than librarians, because you can trade both pumpkins and watermelon (which the crafter block now makes less of a pain to store). In terms of auto farmers with chests for overflow storage, watermelon + pumpkin are much more emerald dense than paper too (6 pumpkin/4 melon per emerald vs 24 paper per emerald). Plus you can trade for golden carrots with maxed farmers, which are one of the best foods for hunger saturation and can be used to breed horses.

Pumpkins can also be used to craft jack-o-lanterns, which are convenient early in the game as lit blocks, and the seeds can go straight into a composter (which you'll conveniently have right next to the farmer).

Also you need leather to craft books (unless you buy bookshelves and chop them down, which I find annoying), which brings us back to cows, and if you have cows you may as well have sheep and pigs, and a butcher.

By the time you can craft sugar cane auto farmers you can craft pumpkin auto farmers, which are more emerald efficient. Until then I would recommend a meat farm (pigs/sheep/cows) to level butchers, and sweet berries (which grow insanely fast and just need dirt and light) for emeralds.

Crazy Frog.

I donate to food banks and educational charities. I grew up with little and now I'm better off thanks to charities and scholarships that supported me, and I want future generations to be given the same chances I was.

CUPS is installed on the majority of desktop systems. One of the listed CVEs indicates that port 631 is by default open to the local network, so if you connect to any shared network (public WiFi, work/school network, even your home network if another compromised device gets connected to it) you're exposed. Or a browser flaw or other vulnerability could be exploited to forward a packet to that port.

In other words: While access to port 631 is required first, the severity of the vulnerability lies in how damn easy it is to take over a system after that. And the system can be re-compromised any time you print something, making this a persistent vector.

And miss out on the sweet release from this mortal coil?
