From MSDN, where else:
An async method provides a convenient way to do potentially long-running work without blocking the caller's thread. The caller (say, M1) of an async method can resume its work without waiting for the async method to finish. However, M1 typically uses the await keyword so that it returns immediately, allowing M1’s caller to resume work or return to the thread’s synchronization context (or message pump).
Does anyone else read that, in the second sentence, the caller is called "M1", but then in the third and fourth sentences, M1 is the "callee"?

Why did they even used M1? Caller is not really that big of a word.

Did you forget that you were reading MSDN?

No.
M1 uses await when it calls some other async method, and hence returns "immediately" allowing M1's caller to resume from the call site.

OK, you tell me. Is M1 the caller or the callee?
If I bend my mind enough, I think I see what you're saying.

It's both the caller and the callee. In the first sentence, it's the caller (of the async method). In the next sentence it's the callee.

Ok let's work through this. This is the way I understand what is being said. Note though that I am no "async" expert. In fact, I've never used the construct in C#. So, take it for what it's worth.
An async method provides a convenient way to do potentially long-running work without blocking the caller's thread.
This seems straightfoward.
The caller (say, M1) of an async method can resume its work without waiting for the async method to finish.
"The caller (say, M1)" -->
M1()
{
await asyncMethodName();
}
However, M1 typically uses the await keyword so that it returns immediately, allowing M1’s caller to resume work or return to the thread’s synchronization context (or message pump)
SomeOtherMethod()
{
M1();
M2();
}

I want to buy a tablet where different people can log in and access individual email accounts. I know Apple is out, what about Android? Or is a surface for me?
Thanks.
Regards,
Rob Philpott.

Android does support multiple users: I haven't tried it (because Herself is scared stiff to go near my Nexus 7, thankfully) but this explains the procedure: http://www.dummies.com/how-to/content/how-to-add-another-user-to-your-android-tablet.html[^]

I think that Android devices are mainly to surf the web, check social media, check emails and play games. As soon as you want to get more work done (Powerpoint, Word, Excel and so on) a Surface tablet would be the best choice, since it is relatively close to a full-blown Windows OS.
I gots a Surface, and I am really happy with it.

Ditto. And my Surface Pro 2 has pretty good battery life, depending on what you're doing, of course.

After much jiggery pokery with the video card settings, I eventually managed to get the Oculus Rift working consistently last night.
Today, Sasha, my youngest (6), had a go of the RiftCoaster demo......http://www.youtube.com/watch?v=c34VL0_9K-4&[^]
She was quite happy to go round and round, me on the other hand was really starting to get a little bit disorientated after a couple of runs. 
Even for the relatively low quality, you do get totally immersed in the content.

I love her reaction!
But my only problem with them is the same as all the other VR headsets that have tried and failed: you don't half look like a pillock wearing them...

That is a downside of a lot of things, not just VR stuff. Take Hardhats, safety glasses/goggles or even cycling helmets!
Nothing can beat Crocs though!

...or are the generation that are coming though being taught not to think?
I'm increasingly noticing in QA that (not only is the standard of questions still dropping) but the thinking element of working with answers is getting less.
For example, a question asking how to remove the spaces between numbers without removing them at the start or end of the string. Understandably, String.Replace and String.Trim don't work. So I suggested a Regex, using his example as an input:
string input = " 2365 2365 ";
string output = Regex.Replace(input, @"(?<=\d+)\s+(?=\d+)", "");
What surprised me was getting a response saying that it didn't work because I had hard coded the string.
Now, you, I, everyone I know would look at the code above and see an example of the input to show where it goes in the regex - wouldn't you? I can't think that anyone who has got far enough to realise that Replace and Trim don't do what he wants, and use Google to find us here should have a problem with using the example to create exactly the code they need. OK, the Regex itself may be a little impenetrable - they do tend to be - but the code around it should be self explanatory, shouldn't it?
Now, I don't want anyone rushing off and downvoting or insulting the OP - hence no link to the question - but I can't help thinking that the next generation as a rule are just not thinking, even when given a solution that needs a tiny bit of input.
Is it just me? Am I getting too old for this? Or is anyone else noticing as well?
