I mostly agree, however, I don't really feel it's performance is so poor as to be an issue.
Well it was mainly that of me expecting near c-performance as that was a stated goal, however I also think the lack of (my expected) performance is primarily due to the lack of a mature gc and better optimized math functionality. Maybe I should do a tip build to see if there's been any substantial improvements of late.
I do really miss the union type, however, if I remember correctly there was issues with the gc (and interfaces can cover in language needs to a certain extent.)
Yes I can see it potentially causing problems for a memory safe language like Go, still it's really only a problem if you are using external code like c-libraries, if you code 100% in Go I presume you can efficiently design around a need for it.

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.

Nokia has posted its quarterly results for the first quarter of 2013, and just like the quarters that came before, there's not a whole lot of good news in there. The rise in Lumia sales still can't even dream of making up for the sales drop in Symbian phones, and when broken down in versions, the sales figures for Windows Phone 8 Lumias in particular are very disappointing. In North America, Nokia is getting slaughtered.More Features »

Well looking at Go (which is what this article was about) it's far too early to evaluate if it will 'stick' or not, but in my opinion it's off to a good start.
My main languages are Python and C, and I think Go lands somewhere in-between with some nice built-in concurrency features.
I've only played around with it sofar, here's a small rundown of likes / dislikes:
likes:
fast compilation (as in fast!), simple clean build system
clean language syntax
interfaces!!
goroutines, channels
multiple return values, duck-typing, defer, composite literals
data initialized to zero
dislikes:
at times rather poor performance for a static 'aiming at c-like speed' language, however it's still very young. Gccgo gives greatly improved performance in some programs.
lack of a union type, started calling some c libraries using cgo only to notice that accessing union data required awkward and slow runtime reflection.
no implicit type conversion (death of a thousand casts)
non-optional garbage collection (however given Go's target domain of concurrent programming I can understand the rationale behind this choice)
Anyway, as I said I've only played around with it briefly sofar but I'm thinking of diving into it seriously, anyone have a beyond-the-barebones Go programming book to recommend?
