So, you disagree that the right and conservatives cling on to the older concepts, hierarchies, as well as racial and patriarchal structures of society, not because they have been proven as better, but because they had more control over women and people in general.
This is described as reactionary, a core element of the right; whereas the left wants societal progress, despite or because it breaks up old hierarchies and crusty structures, and gives people equal chances, empowers them through education, wants to set them free through collective ownership.
The whole political orientation is a scale, although not of two dimensions, but more, for example if we consider fiscal and corporate views.
But the terms left and right are definitely a valid spectrum and description of social progressivism vs. social conservativeness.
The cynic in me thinks that some young men are disappointed that the patriarchy is falling, partly because (young) women are more empowered and self-determined, and they no longer own women. Which is a good thing.
Paper itself is a series of patches over the official vanilla server implementation. You can convert a vanilla server to a paper server just by replacing the vanilla server.jar file with a paper server.jar one, and converting back to a vanilla server can be done fairly easily (but a bit more difficult than dropping in)
It's much, much more performant, and able to handle a lot more players/chunks loaded/etc on the same setup compared to a vanilla server. Along with significant performance improvements out of the box, it also adds more configurations (vanilla has server.properties, but papermc adds paper.yml) which allow you to hand tune optimizations[1], from things like disabling player collisions, disabling block updates for certain laggy blocks, etc. These changes are configurable because they trade off expected vanilla behavior for better performance.
The real strength of paper though is that they do all this while also implementing the spigot API, which enables paper server owners to use a wide variety of server mods[2] that can allow you to add things like minigames, anticheat, etc while still being compatible with unmodified clients.
Most would consider it to be vanilla, when "vanilla" is used as a descriptor of the gameplay (i.e., as opposed to "modded"). There are some very minor differences, but almost anyone advertising a vanilla Minecraft multiplayer server is going to be using Paper or one of its predecessors/competitors. The released server.jar just really isn't optimized for more than one player.
Some things that you can tweak for performance reasons also affect gameplay. For example, you can tweak the radius at which items group together into stacks of entities. Enabling this can make certain farm builds not work, e.g. a piglin bartering farm might have the gold bar destined for one piglin merge with the bar destined for a neighbouring piglin, when in pure Vanilla settings that might not happen. Similarly, you can have XP orbs merge into single orbs with higher XP values. But this drastically changes how long it takes to use an efficient XP farm, where normally you would be waiting for minutes for your player to receive the XP one orb at time.
I much prefer Fabric server to Paper. Paper has a couple game-breaking differences in advanced redstone, and Fabric in general has more mod compatibility. There are options to disable the redstone differences, but it's a bit annoying.
Basically just enable the unsupported settings. My players were happy with the end result of each one I flipped on so presumably the behavior was as expected.
Github has blocked the repository without specifying a specific reason ("due to a terms of service violation").
A possible reason could be that there was an .exe in the repository that was compiled with a corresponding assembler. But is that really enough to be deactivated? Many repositories contain .exe files.
Not an excuse, but github has been under an attack whereby someone was creating thousands of repositories to distribute malware. I'm guessing this got swept up in the effort to prune out the real offenders
It may not be obvious if you're just looking at the book. But if the images of the front and back are put together side by side, like in the post, I think it's quite obvious. I'd be surprised if this wasn't intentional.
