MAX OS X and GCC Compiler - From the Apple Store!
Post 2997 by alwayslearningunix on Friday 15th of June 2001 05:07:05 AM

I have not had the pleasure of building a OS X kernel myself, but I have checked out the operating system since reading this thread and I have to say I am as excited as Neo about this - if Apple take the correct approach and open the source to allow people from all over to modify and scale the operating system, this could be massive. However that is a big if - it has it's advantages and disadvantages to Apple, we're just going to have to wait and see.
On the scalability issue still, OS X Server seems to me to provide a fair amount, I think the figures were something like over 1,000 simultaneous user connections, 4,000 open files per process, and there is support for multiple 100Mbit NIC's - sounds like it is moving in the correct direction. However I don't think it's a good route for Apple to go down if it involved releasing a desktop OS X and a Server OS X, it sounds too much like Windows, and we all know that the scalability in that operating system is an addon, rather than intrinsic to the actual kernel as it is, and always has been, with UNIX.
Sounds like Neo is right - we have to hope Apple release the source. Other than that I'm off to look at prices of Mac's, this has got me more than a little interested

SubmitDiagInfo(8) BSD System Manager's Manual SubmitDiagInfo(8) NAME
SubmitDiagInfo -- sends diagnostic information to Apple SYNOPSIS
SubmitDiagInfo DESCRIPTION
SubmitDiagInfo is a system process which runs periodically. If the user has opted-in for automatic reporting of diagnostic and usage infor- mation, then SubmitDiagInfo collects and sends to Apple any recent diagnostic information which has not yet been sent to Apple. SubmitDiagInfo also cleans up any diagnostic and usage information which was created more than one month ago and is no longer needed. Sending diagnostic and usage reports to Apple helps us improve the quality and performance of our products and services. It helps Apple identify common usage trends and issues that enable us to allocate our resources efficiently, and it helps us provide better support services to you and other customers. All of the diagnostic and usage information is collected anonymously from your computer in a way that does not personally identify you. Reports may include the following information: - Details about application or system crashes, freezes, or kernel panics. - Information about events on your computer (e.g. whether a certain function, such as waking your computer was successful or not). - Usage information (e.g. data about how Apple and third party software, hardware and services are being used). Automatic reporting of diagnostic information is off by default and no information is sent to Apple unless a user has opted-in to automatic collection of diagnostic information. A user is offered the opportunity to opt-in for automatic collection of additional diagnostic and usage information after the user has manually sent a crash, hang or panic report to Apple. Users may at any time opt in or out of automatic reporting in the Security & Privacy pane of the System Preferences application under the "Privacy" tab. All diagnostic and usage information which is eligible for automatic reporting is visible in the Console application under the "DIAGNOSTIC AND USAGE INFORMATION" heading in the application's sidebar. (The information appears here even if a user has not yet opted-in for automatic reporting.) For security purposes, some system diagnostic information will only be visible to admin users and will only be submitted when an admin user is logged in. Users who need technical support should use http://www.apple.com/support or other authorized support channels. Developers who are ADC mem- bers should submit bug reports using http://bugreporter.apple.com in order to allow for two way communication between Apple and the bug reporter. SEE ALSO
