File:Blackberry Playbook OS 1.0.8.jpg Nominated for speedy Deletion

[edit]
An image used in this article, File:Blackberry Playbook OS 1.0.8.jpg, has been nominated for speedy deletion at Wikimedia Commons for the following reason: Copyright violations
What should I do?

Don't panic; deletions can take a little longer at Commons than they do on Wikipedia. This gives you an opportunity to contest the deletion (although please review Commons guidelines before doing so). The best way to contest this form of deletion is by posting on the image talk page.

  • If the image is non-free then you may need to upload it to Wikipedia (Commons does not allow fair use)
  • If the image isn't freely licensed and there is no fair use rationale then it cannot be uploaded or used.
  • If the image has already been deleted you may want to try Commons Undeletion Request

Renamed?

[edit]

After checking numerous primary and secondary sources, I have yet to find an explicit announcement that RIM renamed BlackBerry Tablet OS to BlackBerry PlayBook OS. If someone can provide a reliable source that explains the relationship between the two products (fork, rename, different UI, etc.), let's document it in the article. – Ringbang (talk) 02:54, 23 February 2012 (UTC)[reply]

Wasn't this line killed

[edit]

Shouldn't this article be in the past tense? I thought they killed the tablet line. CaribDigita (talk) 19:05, 8 October 2015 (UTC)[reply]

Multitasking

[edit]

Hard real time allocation: The micro-kernel architecture operating system provides hard real-time multitasking. QNX was one of the first POSIX operating systems to employ the technique of hard time allocation on a fixed clock cycle. The kernel will visit each and every task at least once every cycle, for instance every 20 milliseconds (or 50 frames per second, in graphics terms), to be sure that no task is not attended (or no object entirely unrendered, in graphics terms). This model achieves most of the advantages of the interrupt-driven and polling approaches to multi-tasking. QNX Neutrino kernel calls support threads, message passing, signals, clocks, timers, interrupt handlers, semaphores, mutual exclusion locks (mutexes), condition variables (condvars) and barriers. The kernel is built on these only, making QNX "fully preemptible, even while passing messages between processes; it resumes the message pass where it left off before preemption." This alleviates problems of sudden power-outs or user actions that force resources to be swapped out of working memory – common in tablet applications.[1]

Bound multiprocessing: The micro-kernel was designed for distributed processing, which reduces heat and energy usage by comparison to monolithic architectures such as Linux. The ability to lock software tasks to specific cores, under the control of a single copy of the OS, lets all resources be "dynamically allocated and shared among applications. During application initialization, however, a setting determined by the system designer forces all of an application’s threads to execute only on a specified core" thus reducing inter-processor communications overhead and keeping the bus clear.[2] This approach lies between symmetric multiprocessing and asymmetric multiprocessing.


Note: this seems excessive intricate detail. K.e.coffman (talk) 04:01, 17 October 2016 (UTC)[reply]
