Microsoft said today that users can now run Docker inside a Windows machine and manage Linux-based containers with the new Docker Command Line Interface for Windows. Now many I can figure out how it's different from VMs

Just had a discussion with some Cow Orkers today about Docker as I had the same question (How's it different from a VM). Answer was surprisingly simple.
VM means:
- Host OS,
- Each VM has a guest OS
- if a machine has n VM's, then that's n+1 Operating Systems running. Even if they are all the exact same OS
Docker means:
- Host OS
- Each "VM" only has apps installed
- if a machine has n VM's, then that's still only 1 OS running. Caveat: All the VM's must have the same OS.
Virtualizes the OS, instead of the machine, I guess you could say.

Thanks. That does help. I'm still not clear on the "how does it virtualize calls to the OS, especially where it might need to serialize something" part.

At the high level (don't ask me to explain at a lower one); Docker's magic creates application sized sandboxes and keeps hosted apps from touching anything outside them. Just like modern web browsers create web page sized sandboxes and keep the javascript in them from touching anything belonging to other pages or the rest of the computer.

Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

Kent's never-ending quest to understand Docker plods on...

C++ was stagnated for many years, and many developers was confident that the language will have the same destiny as Cobol, Fortran and VB6. #include is old, they should update it to @import to be really 'with it' and 'cool'
|
|
|
|
|
C++ needs (since when it is an autonomuOH SHEEZ IT'S ALIVE!AAARGH!) to fix something that ain't broken, so it can suck like all the other languages.
|
|
|
|

You really think #include isn't broken? Ever wondered why C++ has enormous compilation times compared to other languages. Ever wondered why macro definitions can break builds?
If you really think that, you're out of step with the standards committee themselves, who acknowledge the problems and are designing a module system. There task is complicated by the requirement for backward compatibility, but at least they're not totally blind.

# define import include
Done.
(Not that it would work.)
|
|
|
|

But it's still missing those sexy '@' characters instead of those stodgy '#' octothorpes. (Which autocorrect wanted to fix as clotheshorses. I don't imagine that would have made sense).

Spend enough time on the web and you're bound to come across TRUSTe's logo. It signifies that the site you're on -- like eBay, Yelp and Etsy -- self-certified with TRUSTe's set of membership requirements like the Children's Online Privacy Protection Act (COPPA), the EU-US Safe Harbor Framework and generally has an eye toward keeping any of your sensitive info safe. It's like you can't trust(e) anyone anymore

If you were teaching a programming course, what language would you teach it in? "You create a universe by perceiving it, so everything in the universe you perceive is specific to you."
|

I don't think choosing a language is as important as it might seem. Almost all modern languages share the same concepts, such as conditional statements (if/then/else), loops (for/do/while), subroutines and object oriented concepts (such as classes and polymorphism).
Think of teaching programming similar to how you'd teach an automotive mechanic course. The concept of how most cars work (internal combustable engine) is the same whether its a 1963 Ford Mustang or a 2014 Nissan Sentra. There may be some variances between different cars, but they all work basically the same way (spark plugs, engine, pistons, etc).
That being said, I would choose a language that you are comfortable with and just use that (assuming its not some outdated or weird language, such as Cobol or LolCode). Focus your teaching on programming concepts rather than the semantics of the language.
I hope this helps!

 That's the main point.

For the entire time reading through the blog, I was really wondering what was going on..

As with everything It depends.
If it is a beginners course then use something that does not require them learning more than they need to just to get something simple to work.
Like C/C++ you need to know compiler settings and the includes etc..
Java script you need to build a container with something else.
WPF you need to lean the WPF syntax and the underlying Language like C# or VB.Net.(It is sorta like trying to learn HTML and Java Script at the same time.)
So stick with something that you can quickly demonstrate the "basic concepts" that will later translate to any language.
If it is more advanced then that is the answer, use the specific language for the task that needs solved.
You also have to take in consideration your students and how advanced can you start them out at.
If it is to easy they will get bored.
If to difficult then they will get frustrated and give up on it.
