In fact I am sure that when people post such things about the danger of Tylenol on boards, those people are considered trolls and maybe even modded down or kicked off.This is the problem with complaining and trying to ban trolls. Trolls are often simply people you disagree with, or simply people who bring up facts you don't want to deal with.
Trolls may in fact make the discourse of the internet less enjoyable, but it also has a built in bullshit detector called everyone else. And each of us adults has a responsibility to think critically about statements that are made.
For instance, when I first heard this I immediately asked how could a software update effect the charging hardware. How could a software update effect the ability of the hardware to handle hard radiation. And by what mechanism could the battery be charged.
Of course some of these questions come from a hard science background, not something everyone has. But still isn't the problem that so many in the population just believe and repeat whatever they are told by authority figures. Is the problem really trolls, or that a certain subgroup of people just want to believe in the magical solutions promoted by their revered charlatans.
About the only reason that the smartboard is useful is because administrators like teachers to stand in front of the class and pretend to teach. Although writing on a slate or ipad and having it show up on the board can be better, the teacher standing in front of the room is still seen as the old fashion as the better solution.
If I am honest, though the smartboard software is bloated, there are some things it does very well, although it is still better to not use the smartboard. There was a time when the board itself was interesting to kids, but now they all have smartphones.
So to answer the question, if there is not something in the software that you absolutely have to use, like the math symbols, then don't use it. Download mobile mouse or something like it to control the computer. There are many drawing apps that will allow you, or any student, to write. I have a slate.
As far as the updates, most applications seem to update when a new iOS comes out. I have not seen an inordinate number of updates. As the Apps have to not only deal with a new OS but also new screen sizes, Apps that are not written to run on many screen sizes will obviously have to be updated.
My problem is that Apple is reintroducing the cloud disk service, a la iDisk, but it is not going to available on mac until the next MacOS, which is not going to be available for at least a month. Those who upgrade when they upgrade their phone will lose access to data on the Mac. There does seem to be some feature bloat at the expense of efficiency.
We see this in other industries. The F150 is now aluminum, which required not only the entire production line to be redone, but also supplied of aluminum to be created. This is only profitable because Ford sells about 10,000 of these trucks a week, and that is a number that has been falling since a high in about 10 years ago, though in recent years the sales have increased.
As far as why this is allowed, it is a lot of money. The banks and firms who are managing the IPO are US and will make a lot of money. The persons and firms who are allowed to buy or are given the stocks will make a lot of money when they resell the stock, either immediately, or in a few months when principles are allowed to resell stock.
It seems that the sale is on shaky ground, given that the Chinese government can likely do any number of things to make the shell company worthless. I think what some may be hoping is that the Alibaba can quickly expand out of china and preserve value as a worldwide conglomerate type thing. At a basic level this is further indication that there is a lot of capital out there, and for some reason the people who have it think it is better to risk it on the occasional potential high return scheme than use it to build long term infrastructure. I guess no matter how much money one have, one always is susceptible to a get rich quick scheme,
I've noticed several design suggestions in your code.
