HOW DOES SENDING EMAIL OVER ENCRYPTED CHANNELS "PREVENT" EMAIL ADDRESS TYPOS?
It does insofar as the public keys of the intended receiver and the actual receiver don't match, and thus the actual receiver gets nothing but encrypted gibberish, thus no data is leaked.
The Raspberry Pi has the hardware to be very cheap while still being able to connect to a general lab setup and powerful enough for a lot of nice little projects.
What we have is only the governmental mandate that an ISP with a local monopoly of lines has to offer capacity on the last mile to other ISPs in a non-discriminatory manner. That's all. Thus about every ISP is potentially able to offer his product everywhere. If he is not present with its own lines, they can be rented from the local monopolist or quasi-monopolist. Problem solved.
But in general, getting more sheer power out of a certain engine size or configuration is not so much of an engineering problem (e.g. just add lots of chargers, and don't forget the cooling). It's more of a design decision if you want to have better all day behaviour and more stability under load, or if you want more impressive data sheet numbers. You surely can tune the Bugatti W16 to put out 1300 or 1400 hp and still being street legal, but what's the point? Koenigsegg decided to go a more extreme route, getting more power out of their engine, knowing well that their cars won't be used in the daily commute anyway.
So the Earth surface is indeed getting warmer since the times we started to record it, which goes back in some regions to the 18th century. If the average temperature of the Earth's surface is getting warmer (which it does at least since we started to measure it), and if it is happening globally, there is good reason to call it Global Warming.
That there can be local warming that is even larger, or that there are locations which are colder on average now than they were when we started to record temperatures, is quite possible. The region I live in has gotten 2 K warmer on average since the begin of the records (which were somewhere around 1760, thus encompassing the whole era of Industrialization), much larger than the 0.7 K on average we measure globally. So there surely are regions which warmed less than 0.7 K on average.
This is a fact you can read at NOAA or whatever organisations keep record of local and global temperatures.
Where the theorizing starts is if this trend continues in the future, and what causes the Global Warming. But the single fact that the Earth's surface got warmer globally and on average is no hypothesis, is a fact we have measurements of.
