[Yr11 Information Technology] Re: Google 'Go' .. a new programming language

Some details for those of you that asked me off list. There is a free and
informal public workshop this Saturday morning at Melbourne Docklands for
computer-code noobs like me who are looking to access advice about these new
tools. Last month I got some assistance with how to tweak my VMWare settings
for an Ubuntu Linux VM I was building for school. For more details, public
transport or parking information:  http://tr.im/EMYv

It is a good chance to meet other Open Education minded folk with some
really nice coffee and breakfast just a hop, skip and registry shift away.
Wireless access, warm morning sun, delicious danish scrolls as I lay back
and reflect on the reports I could be writing or grass that needs mowing ..
( ahh bliss)  :-)

> One of the most appealing parts of Go is its ability to handle multicore

>
> Existing systems languages like C++ evolved long before today’s modern,
> and very fast, processors hit the market and make supporting multicore

> While Google could have concentrated on writing libraries that can handle

> include files, lack of concurrency awareness — are rooted in the design
> of the C and C++ languages themselves," and decided it was time for
> something entirely new.

> At the moment, Go is still very young and experimental.

> Even Google isn’t currently using Go in "large-scale production"
> applications. While the site that’s hosting the code is running a server
> built with Go as a proof of concept, the primary purpose of this release
> is to attract developers and help build a community around Go.
>
> Despite its fledgling status, Go already supports many of the standard
> tools you’d expect from a systems language and even includes support for
> other Google tools like Protocol Buffers.
>
> Also, it’s worth noting that Google’s Go is not to be confused with an
