Out of tune ad ballad draws few fans
Well, Research in Motion ... er BlackBerry, Ltd. (
) finally pushed its QNX based
BlackBerry 10 platform
out the door. It's celebrating by releasing
another interesting YouTube video
(Is it an ad? We don't know!).
Some are questioning BlackBerry's judgement in continuing to post such strange advertising pitches to its developers account. One user "Tron5500" writes, "Come on blackberry ! Your scaring away all your potential customers..."
And Calum Redhead writes, "Is this a joke?"
Another user types "awkward", while another commenter quips, "wow this is just absolutely horrible. i want those 3min of my life back."
The song lyrics are as follows:
At last my love / has come along / our lonely days are over / now for one last little song / At last / All the promise has come true / Your games and apps / Are in the storefront / On our new platform / Built for you / At last /
Two new devices
good to go / Complete with legendary keyboards / Blackberry Balance Hub and Flow / At last / A new beginning a new start / This is gonna be a blast / Blackberry 10 at last.
... just in case you BlackBerry fans want to do a cover or something.

QNX doesn't scale well for this use
3/19/2013 8:36:19 PM
Microkernels run several parts of the OS in separate modules in user space memory. Mikrokernels like Mach were found to perform poorly:
Apple took Mach with parts of BSD components and adopted it into a hybrid/monolithic design because of the slow performance of Mach is a microkernel. OSX, Linux/Android, Windows, BSD etc. all use either Monolithic or hybrid kernels.
QNX is used mostly for small embedded devices before now. Apple, Microsoft, the Linux kernel team, and the BSD's all believe pure microkernels perform too slowly or they would have been using them before now.
BB10 represents one of the first times in the last couple decades a true microkernel will be used for a user operating system.
If the system isn't slow due to inter-process communication they are going to prove a lot more people wrong than just me.
It's also possible that owning QNX they have made customization to the design and moved some functions from user mode/memory to kernel mode/memory to reduce message passing/IPC and improve performance. This would make it more of a hybrid kernel but so far I've not heard this at least.
