"Now everyone can use Google's Go language on the company's App Engine cloud platform as the company has announced that the Go runtime, which has been in development since it was announced at Google I/O, is now generally available."

C++ and dependency nightmares? Please elaborate on your statement there.
Where there's sloppy design, there's dependency nightmares: where there's proper design, there is not. This is not specific to C/Objective-C/C++, as all languages that allow forward declarations/references (and languages that don't are rare) allow for circular dependencies, which is when things balloon out of control and become dependency nightmares.
What do a lot of more recent languages have that C/C++ doesn't provide built-in? The import statement (or equivalent) where you don't have to go out of your way to define something to say it has already been included. That's all. Note, however, you can still ensure things aren't included more than once in the same compilation unit, with proper usage of the preprocessor.

Go does not use header files at all, and unit/package scope is controlled through simple syntactic rules (anything starting with an upper case letter is externally visible, otherwise it is private).
Where there's sloppy design, there's dependency nightmares: where there's proper design, there is not. This is not specific to C/Objective-C/C++, as all languages that allow forward declarations/references (and languages that don't are rare) allow for circular dependencies, which is when things balloon out of control and become dependency nightmares.
Hence why Go does not allow forward declarations (I guess it is one of those rare ones you speak of). You define things once and only once - there is never any need (or even support) to do otherwise. Since there is no type hierarchy the need for forward declarations doesn't exist.

I don't do much C++ development (I very briefly dabbled in it a few years ago) - my understanding of the nuts and bolts of compilation and dependency resolution are very limited.
I can say though, that in trying to write a reply to you here I did do some reading up on how whole header/preprocessor/etc. combination works in C++. Suffice to say that after reading for about an hour I still don't understand it. The "rules" in Go can be explained, pretty much in their entirety without omitting anything important, in a single sentence. Quite a contrast to me, just saying...

So, the Xbox One disaster continues. Microsoft's policy for dealing with the used games market has reportedly leaked - and it's a clear and direct attack to destroy the used games market. Prices for used games will be set at the retail value of a new game, and retailers have to hook into Microsoft's computer systems and comply with Microsoft's terms and conditions.

At an event earlier today, Microsoft unveiled the next Xbox - the third model, but confusingly named Xbox One. The big focus was TV, integrated Kinect, and all the other stuff we all expected to be forced down our throats. I think it took them 25 minutes to actually come to what should be the core of the story: gaming. Nothing groundbreaking in the gaming department, except for how Microsoft intends to handle the used games market and borrowing games from friends: pay up, buddy!

The day has finally come! Jolla has finally announced the launch device for its Sailfish operating system - and by god this is a looker. It's decidedly different from other phones out there, but it has good specifications and carries a relatively reasonably price tag - EUR 399, and it's up for pre-order today, shipping in the fourth quarter of this year.

Why does Google get so much credit in the technology industry? Why, despite the company's many obvious failings, do many geeks and enthusiasts still hold a somewhat positive view on the all-knowing technology giant? A specific talk at Google I/O this week provides the answer.

"Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is one of those news items that's fun to write, fun to read, fun to comment on, and where no one will be able to say anything unkind. It's all just one big ball of awesome fluffiness. TuneTracker, the BeOS radio automation software, has just released something very special: TuneTracker System 5, the first version designed entirely and specifically for Haiku. In fact, it actually includes Haiku in the software package. Better yet, TuneTracker also unveiled several system-in-a-box products - which have Haiku and TuneTracker pre-installed.

Exactly twenty years ago, a document was published that played a huge role in establishing the web as we know it today. Twenty years later, and this simple and straightforward document is proof of an irrefutable fact: while closed technologies can change markets, open technologies can change the world.

Oh multitasking. That staple of computing that got thrown out the window with many modern smartphones. We got some rudimentary thing in its place - but even as multitasking on phone and tablets improves, its user-visible side remains cumbersome. Windows 8 has a neat implementation, and now it's time Android follows in it footsteps.

They're here! Whether that excites you or not remains to be seen, but the Galaxy S4, which will most likely become the best selling Android smartphone of the year by a huge margin, has been reviewed by all the major sites, and there's lots of interesting conclusions in there - although I think most of you will get the gist.More Features »

Regardless of the timing, I really don't think it's related.
My understanding, from listening to various talks on Go programming, was the developers behind Go wanted some very specific qualities in the language they used internally that were either not available or troublesome to deal with in most other languages:
1. The wanted something simple and fun, from both the standpoint of syntax and feature set. They liked Python, but wanted something akin to compiled Python with a more conventional syntax and static typing.
2. They wanted something that could do most of what C++ could do, without the dependency nightmares and slow compilation speeds.
3. They definitely wanted garbage collection, but they also wanted to allow the developer some control over it. In Java and most other languages the GC has a tendency to become a barrier to optimization efforts. They wanted automatic memory management, but they also wanted to retain programmer control of the granularity of the allocations and still have pointers.
4. They wanted to build concurrency features into the language without resorting directly to hardware threads. I.e. make concurrency simpler.
In my opinion it succeeds at all of these. It is still immature, and I have not myself done any serious development with it, but from toying with it I have to say I like it very much. I do see it as an attempt to replace Java, but more for technical reasons than anything else.
