I don't see it being a big deal though since the general rule of thumb of developing on Android is you choose the API level which supports what you want to do in your app. Most apps don't need proximity payment services or fingerprint reading APIs so they'll use a lower API level and they'll work across any device that supports that level.
There are obvious advantages to what Apple does, but it is a monoculture and there are disadvantages to that too. The biggest one for handset owners is once you're cast into the darkness by Apple you're pretty much screwed. Android devices might not get so many firmware updates but they tend to still get the latest apps from Google and updates for other apps that already work on their platform.
There is nothing to "gloss over" since it is obviously hard. Perhaps it boggles your mind but people tasked to do it would break it down into small manageable problems and would come up with practical solutions and contingencies.
It is likely that any human landing to Mars would make extensive use of robotics, possibly with missions beforehand to prepare a site, drop supplies etc. It is likely it would require water but that a nuclear reactor could produce the O2, distilled water and power for life for humans, plants etc. It's likely that the persons would live in a pressurized structure which could be partially or fully buried to shield it from radiation. It is likely that suits would contain extra shielding and humans would only venture outside when the sun was low in the sky and that there would be covered trenches / walkways to travel between any structures.
Perhaps it's all mind boggling to you. I suggest other people see it as a hard but surmountable challenge.
That isn't to say that all immigrants are welcome of course and some of them are decidedly unwelcome (trafficked slaves, criminal gangs etc.). But it's overblown by the media, particularly those adept at pushing the fear button on their readers like the Daily Mail, Telegraph etc.
It's also clear that you're skipped set theorem and logic when you leapt to the wrong conclusion about what I wrote.
Ironically the SNP are pro-Europe which makes it all the more bizarre. How can union with England, Wales and Northern Ireland be bad but union with France, Germany etc be good? Same for Sinn Fein. So it's likely if the UK left Europe that Scotland would break from England and become part of the EU. I could see Northern Ireland doing the same. What fun that would be.
Leaving would be economic suicide so I expect Cameron will extract some concessions to persuade people to stay in and dodge that bullet. Because if he doesn't it's likely that the UK will leave the EU and Scotland and Northern Ireland would leave the UK. That would be Cameron's legacy and he knows it as much as anyone. It's probably why the Conservatives are already trying to take the bite out of some of the pro-exit talking points by tackling illegal immigration at the moment.
I don't know what constitutes bot use in WoW but if the bot is designed to enable automated levelling then it's a big no-no. I wouldn't be surprised if a lot of the gold farmers have such bots running on an almost factory-like basis.
