Rigorous and strict 2PL Lock, is there any advanatge, Local Contest Questions?

In 2PL (two phase locking), what advantage(s) does the rigorous model have over the strict model?
I) There is no advantage over the strict model.
II) In contrast to the strict model, it guarantees that starvation cannot occur.
III) In contrast to the strict model, it guarantees that deadlock cannot occur.
IV) In contrast to the strict model, there is no need to predict data needed in the future.
My note says all of the above are false. I am a bit confused. Can someone clarify for me why all of this is false?

When updating to the latest OS X my wife's Mac Book Pro locked at a grey screen with an apple icon and status bar. Is there any way to recover the data on the laptop and complete the OS install?

When my wife's Mac Book Pro was being updated to the latest version of OS X the laptop locked up at a grey screen with the Apple icon and status bar. Is there any way to recover the data and complete the install? I have not tried anything yet because of the data issue. I am not sure which OS X version as I did not install the software.

Used Macs of every description are always available on Ebay and Craigslist and from a plethora of online used-Mac resellers. Apple sells refurbished late-model Macs at 10-20% discounts with a new-computer warranty and the opportunity to extend the warranty with AppleCare.

Also, is there any way to save a group or an open session and then restore it later?

History menu, if it was destroyed in the last session
then use "Restore Previous session:" and then restore all windows also from the history menu.
If done in this session try the restore all windows under the history menu.

No, you cannot downgrade your iOS device. That's not supported by Apple.

My new iphone 5 email is synched with my home office computer Outlook email using a POP account, but deleting an email on my computer does not delete it on my phone and vice versa. Is there any way to get a true synch?.

POP does not support synchronization between the server and clients. You will need to use IMAP or Exchange Active Sync if your email provider supports it.

I have cs4 installed on my old computer, i have since lost the disk and serial #s. Is there any way to recover this information and install the programs on my new computer? I used my old computer for college and haven't used it in awhile, now I have a job that can benefit from having those programs. I was wondering if ADOBE keeps records or something to where I can download the programs on my new MacBook and use my old serial #s.

Find your serial number quickly

MiniDisplay Port (Thunderbolt MacbookPro) to DisplayPort Dell U2410m don't work! The signal only comes as YPbPr, no RGB and bad quality. Is there any solution?

I want to connect my new MacBook Pro via DisplayPort to a Dell U2410m monitor.
But the signal only comes as YPbPr, no RGB and bad quality. Is there any solution?
It works with the mini display port to DVI adapter from Apple but I want to use the DisplayPort.

J~
cmelbourne91 was suggesting HDMI because many of the MDP/Thunderbolt to DVI adapters come with an additional DVI to HDMI (not Apple's) and you likely won't find any MDP to HDMI becuase of something weird with one of the Apple or HDMI related patents and the type of cable/jack/plug required for it.
As for my computer (15" MBP mid 2010), it almost seems as if I have your problem but intermittently. When connected to an external monitor or projector, the thing will project just fine, but then after some time (and no movement of the computer, cables, or screen) the connection quits. Sometimes it comes back on, sometimes it does not, but it basically registers as if there is no external display.
Any additional info on this?

HT4967 Mobile Me was so handy. I pushed the little sync button and everything updated. Is there any equivalent for I Cloud?

Welcome to the Apple Community.
Unfortunately, iCloud does not offer equivalents to Mobile Me’s iDisk, Gallery or Web Hosting services. You will need to find a third party solution to replace these services. You might consider DropBox, SugarSync, MediaFire or any other service that offers online storage. (not all these alternatives offer all the services previously provided by iDisk)

My guess, based on your info and the fact that the shuffle is an older model, is that the shuffle's battery is worn out and not holding a charge. When you plug it in, it functions because it is getting power from the USB connection and appears to charge. When you disconnect it, it goes dead because battery does not hold the charge.
Since you have already tried doing a Restore, the problem is hardware and not software. Unless you want to do the work yourself

the cost for replacing the battery probably exceeds the $50 for a new 4th gen shuffle.

I wanted to know how to view the gifts I've sent to people and (if possible) know if they received and downloaded them. Is there any way to do that, other than asking the person?

I wanted to know how to view the gifts I've sent to people and (if possible) know if they received and downloaded them. Is there any way to do that, other than asking the person? Obviously I want the gift to be a surprise (for my best friend specifically) so asking them if they received it would ruin that.
