Grand Central Dispatch now Open For Business

I recently gushed about Apple's new Grand Central Dispatch code at the heart of the recent Snow Leopard Mac OS X release. Good news. Apple has decided to Open Source the code under an Apache license.

Drew McCormack over at MacResearch speculates as to why in Grand Central Now Open to All | MacResearch:
There could be one last reason why Apple has taken this step: they want to use Grand Central to push the adoption of other technologies, in particular, blocks. Blocks are an extension to C which form the basis of Grand Central Dispatch. Having your operating system based on a non-standard language is not a good position to be in, and Apple would surely like to see blocks incorporated into the C language. By offering Grand Central to the broader programming community, they may be hoping it will catch on, and make the argument for incorporating blocks in the C standard that much stronger.

I agree.

The next step is for this code to be picked up in a Linux Distribution. Having simple concurrent programming, integrated tightly with C code (and C code derivatives) would be a boon to many industries looking to exploit multicore.

    Hi Brian,

    I have enjoyed your links to the Ars Technica articles re: GCD and blocks. I can finally use some of those idle cores on my Mac ;) The open source option is also pretty exciting - my guess is that the move keeps the OS-X dev community healthy since many developers are defecting to their money platform (aka iPhone).
    I trust all is well with you - I see on linked in you are now with HP - congrats. We are a big HP Blade frame customer now - (VMWare + Red Hat) - I think Solaris' days are numbered in our data center. Good luck in the new job.
    Best Regards,
    Greg

Kernel-based Virtual Machine hits Linux

Many congratulations to my good friend Moshe Bar and his team over at (stealth-mode startup) Qumranet . Techworld reports that the KVM (Kernel-based Virtual Machine) project has been accepted into the 2.6.20 version of the Linux kernel distribution. KVM is an Open Source kernel driver that basically allows a Linux kernel to host virtual machines, as plain old Linux processes, that can run Linux or Windows (or other x86-based operating systems). It runs only on hardware that support Intel's VT instruction set (which is fine) and will soon support the AMD-V instruction set as well. This is cool for a number of reasons. It's Open Source, released under the GPL. It basically turns the Linux that we all know and love into a "hypervisor". Linux-as-hypervisor makes sense because Linux already knows how to manage devices, memory, processes, multi-cores, etc. VMware ESX is, essentially, a "hypervisor" - a small kernel, built on Linux as it turns out, that

Bill Coleman Joins 3tera Advisory Board

I think this move surprised a number of people, since Bill recently wrapped up Cassatt Corproation, getting the technology and people  acquired by Computer Associates . However, I was not surprised at all. The announcement, via  3tera Welcomes Bill Coleman : You may or may not have seen the recent press realease.  Bill Coleman, IT/Silicon Valley luminary, Founder and CEO of BEA Systems, has joined 3Tera’s Advisory Board. Yes, this alone is a great testimonial to what we have accomplished in our field.  Getting dignitaries such as Bill does not come easy.  But here’s the best part - this has a lot more than just marquee value and I doubt that Bill would have joined us if that was the case.  Bill, especially since his most recent stint as Founder and CEO of Cassatt Systems, is an extremely knowledgeable visionary in the area of utility and Cloud Computing; and, data center automation. So, Bill will be extremely valuable, reviewing and tweaking both our business plans and techno

Big In Japan Open Sources Their Ruby On Rails Tools

The kind folks over at Big In Japan have graciously decided to Open Source the code they used to build their demo web sites . It's all Ruby on Rails code, and it's being released with a GPL license. The code trees being made available include: elfURL ~ URL Shortner FeedVault ~ OPML file storage FrankenFeed ~ RSS feed merger InstantFeed ~ RSS feeds via email QwikPing ~ Ping Server SocialMail ~ RSS via email Very cool. I just love the Open Source community . I have actually been writing some code of late, and it's great to have some reference code to check out. Not sure if I'm going to go with Ruby on Rails yet, however. And, for the record. I have no idea if this is big in Japan.
