Is there any advantage in performing a clean install?

I'm curious... My 80GB internal hard drive is nearly full so I will be upgrading to a 250GB.
Is there any advantage in performing a clean install of Tiger on the new HDD and then copying across files etc from the old one using migration tool? (the idea being it will cleanse any old files, code from the numerous OS upgrades as it originally had panther on)
Or will the system be just as fast by using the disk utility to copy the contents (OSX and all) of the 80 GB across to the new 250GB and then set that as the boot drive?

If you are asking if there is an advantage to doing an erase and install, then yes, you'll be able to ascertain any of the issues you've been having with Apple software are hardware related issues if before the migration assistant you have trouble with any Apple applications. Cloning one drive to another, you'll find yourself with whatever corrupted fonts, cache, preferences files you had before. I would though make a backup of your data to a second drive before attempting the move, simply because it is wise to have at least two copies of your data at all times.

Is there a way to perform a clean install without the Internet on the computer that my iPhone is backed up on?

I don't have Internet on my PC that my iPhone is backed up to. Without connecting it to the Internet, how can I perform a clean install? Since iOS 7 my battery life has been crap, I've tried everything except a clean install, so this is my last resort but I wanna make sure I can do it before I wipe my phone.

Installing iOS requires an Internet connection, there is no way around this.

I'm buying a new computer for use with Creative Cloud. Are there any advantages to PC vs Mac?

I'm replacing a seven year old Dell that still works but is getting rather long in the tooth. I have CS4 web design. (For PC)
I have a Macbook Pro (so I'm familar with Mac OS)
I'm upgrading my computer to mainly use the Creative Cloud.
Are there any advantages (related to Creative Cloud) to buying a Mac or a PC?
I just don;t wan't to a Mac and then find that many features don;t work that are on the PC (or vice versa)
Or is one interface easier to use than another?
Thanks in advance for any help.

It usually boils down to personal preference.
The software is, to all intents and purposes, the same in either operating system. There are minor differences between them, usually related to the hardware or the operating system. But if you can use the software in Windows, you'll be able to use it on a Mac too.
It's a matter of which environment you prefer: Windows or Mac. I use both daily since the Cloud allows you to install on Windows and/or Mac.

Is there any advantage to use database helper class

Is there any advantage to use database helper class ( e.g. database.bookDB in Duke's bookstore)in servlet design? What if I setup a DB connection for every servlet?

If there is not much relation between servlets.For example one servlet working on authentication againist user name/password in database another one work on searching book by keywords?
and if we want to have servlets written by difference programmers?

Hi there. I am in the process of choosing a laptop to load elements 11 on.Putting minimum requirements aside, is there any advantage in getting a dedicated as opposed to an integrated graphics card, would it run faster on an i5 as opposed to an i3 process

Hi there. I am in the process of choosing a laptop to load elements 11 on.Putting minimum requirements aside, is there any advantage in getting a dedicated as opposed to an integrated graphics card, would it run faster on an i5 as opposed to an i3 processor and does a screen resolution of more than 1024 x 768 make any diference in elements 11? What should I be looking for to enable elements 11 to work efficiently without over specing? thanks folks !

PSE doesn't make big demands on the graphics card, but you want a screen that is at least 800 px tall to be able to use all the features. Some things, like the raw converter, may not appear at less than that.

Are there any advantages of using Secure Empty Trash over regular Empty Trash?

Are there any advantages of using Secure Empty Trash over regular Empty Trash?

If you are going to run around with sensitive files on your file system, you might be better off using a whole disk encryption so that every file is encrypted, any deleted file contains encrypted contents. As long a no one can access your files using your encrytpion keys, all your data is secure.
Also secure delete is not really going to do much on a Solid State Drive, and again whole disk encryption would be a better choice.
For a moderate amount of data, secure erase does not take too much time. But if you have a ton of file and/or a few really large files to erase, secure erase can take a long time to complete as it is doing multiple pass to write and overwrite the file's storage with patterns of data that make it extremely difficult to recover the original data. That takes time.
Finally, if you have been updating a document, previous editions may have been given over to free storage as new versions are written, such that when you decide to erase the file you may only be doing secure erase on the most recent copy.

Is there any advantage to upgrading to 10.7 instead of 10.8?

Adobe has upgraded Connect to 9.3. 9.3 unfortunately isn't fully compatible with my OS 10.6.8. Since I use Connect to tutor students at my online university, I need full functionality. Adobe told me that Connect 9.3 will work with 10.7 through 10.9, but NOT 10.10. My choices are either 10.10 for free, or paying $20 to get either 10.7 or 10.8, unless I know someone who downloaded 10.9 and would let me access their account. Is there any advantage of 10.7 over 10.8, or should I just go to 10.8? I'm thinking 10.8 will probably last longer before Adobe Connect puts out a version that will require me to upgrade again, but I don't know if there were any advantages of 10.7 over 10.8. I kept 10.6 because it allows the operation of Rosetta, which allows me access to all the old emails and pieces I wrote in the old AOL for Mac OS X, but I think some of them I'll be able to open in other apps from the finder at least, albeit with a lot of junk symbols that will make them hard to read. I have to be able to work though, so I need to be able to have full functionality with Adobe Connect, so work trumps personal items I've stored, alas. Anyway, is there any advantage to picking 10.7, or should I just go to 10.8?

Yes, the lack of compatibility with Rosetta is what's kept me at 10.6.8. I used to save everything in AOL for Mac OS X, both emails and things I'd written, until AOL came out with a completely different application and I realized that eventually I wouldn't be able to run the old AOL. Before my last upgrade, from 10.5 to 10.6, I thought I was going to lose the old AOL, so I did convert a bunch of files to Word or pdf or both, and more recently I've converted some others, but I have something like 15 years worth of correspondence and other items, so it would be difficult to convert them all.
Thanks for the articles.
Thanks for the backup reminder. My external hard drive died earlier this week, and so I bought two new ones specifically so that I could backup before upgrading (and so I'd have a backup backup and never be without at least one backup again ).

Hi, I am interested in upgrading to snow leopard but I've heard in some cases it messed up peoples computers. Is there any advantages in upgrading to Snow Leopard from Leopard? Thank you in advance for the advice!

Hi, I am interested in upgrading to snow leopard but I've heard in some cases it messed up peoples computers. Is there any advantages in upgrading to Snow Leopard from Leopard? Thank you in advance for the advice points will be given to multiple users. Here are my computer specs (Leopard 10.5.8.)
Model Name:    iMac
Model Identifier:    iMac7,1
Processor Name:    Intel Core 2 Duo
Processor Speed:    2 GHz
Number Of Processors:    1
Total Number Of Cores:    2
L2 Cache:    4 MB
Memory:    2 GB
Bus Speed:    800 MHz

You need not upgrade unless there is something you do that cannot be done unless you upgrade. Upgrading OS X doesn't mess up anyone's computer. Users mess up their computers.
Your model has 2 GBs of RAM which is adequate for Snow Leopard although 4 GBs would be better. Upgrading to Snow Leopard will cost $29.00. You can order from Apple's Online Store. Here's a good procedure to follow:
How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
Insert OS X Installer Disc into the optical drive.
Restart the computer.
Immediately after the chime press and hold down the "C" key.
Release the key when the spinning gear below the dark gray Apple logo appears.
Wait for installer to finish loading.
E. If updating:
Download and install update(s)
Use Software Update, or
Download standalone updater(s).

Cannot perform a clean install of CF 10 - ODBC Agent and ODBC Server are not in Services - Win2k8 R2

I've tried to perform a clean install on a Win2k8 R2 x64 server several times and I can't seem to get it to install.
I was upgrading from CF 9, which took several attempts. I eventually got CF 10 working and running with the latest updates. But the server would only run for about 15 minutes and everything would come to a screaching hault. ColdFusion pages would fail to load with no error. The pages would hang and wait for the server to respond, which it never did. Restarting IIS would fix the problem.
I have about 20 CF sites on the machine. I came accross an article that talked about pool sizes, etc. I ended up trying a few things with the Web Server Configuration Tool, and as I was adding/deleting servers, I got an error that some application unexpectedly quit, but it wasn't the wsconfig tool. This happened about 3 times as I was deleting servers that I had previously added. Then I tried loading the CF Admin and I got a 500.0 internal server error.
So I bit the bullet and figured I would start all over again. I uninstalled CF 10... now there's nothing on the machine. Re-installed CF 10, and I get the same 500.0 Internal Server Error. I uninstalled, restarted, installed... same thing. Then I found an error in the event viewer that reads:
The description for Event ID 0 from source ColdFusion 10 ODBC Server cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
ColdFusion 10 ODBC Server error: 0
StartServiceCtrlDispatcher Error!
Then I found out that neither the ColdFusion 10 ODBC Agent or the ColdFusion 10 ODBC Server have been installed... at least they're not showing up in the list of services. msconfig also shows that they don't exist at all. I tried reinstalling several times and I can't get them to show up.
PS: It's 6:15 AM and I've been working on this since 10 PM last night. I NEED HELP! Thanks!

Hello,
Once you move your application from any prior version of ColdFusion to ColdFusion 10, you will have to tune your application, as the architecture changed from JRun to Tomcat.
You can refer to the article http://blogs.coldfusion.com/post.cfm/tuning-coldfusion-10-iis-connector-configuration for parameters, that needs to be tuned appropriately to make CF connector works flawlessly.
Hope this helps

Anit Kumar

How do I perform a clean install of ios8 on my iPhone 5

I would like to perform a clean install, meaning not putting ios8 on top of ios7.
Is there an advantage to doing this? When I installed Mavericks on my MBP I had the Genius Bar do it and it was like a new Mac,
So, my thoughts are that a clean install, starting as if it were a new phone would be the same.
Is this true?
How would I do that after backing up through the latest iTunes.
Would I need to set up pop mail accounts from scratch or would that come back in the restore backups
As you can see, I am unsure as to the best way to make my iPhone 5 run trouble free with ios8
Advice and instructions are welcome

Okay....so Apple does have a guide related to Mass deployment which includes a rough way to do a clean OS X Server clean install. You need to use a NetBoot Lion Server as a boot, but it works.
http://support.apple.com/kb/HT4746
Use these steps to create a NetRestore image of an un-configured Lion Server:
Install OS X Lion, and then Lion Server. This server will be used to create the NetRestore image.
On the server, install the app named "Install Mac OS X Lion" from the Mac App Store (a network connection is required for this process).
Install the Server Admin Tools from http://support.apple.com/downloads/ on the server.
Open the "Install Mac OS X Lion" application, and install to an empty volume. This volume can be a spare partition or external hard drive. Be sure to click the Customize button and to select the Lion Server software.
Once installation is complete, the server will restart from the newly installed volume. Instead of completing the setup assistant, press Command-Q to quit the assistant.
Select the option to shut the server down.
Restart the server and hold the Option key.
When the Startup Manager appears, select the volume which you've already configured Lion Server on.
Open System Image Utility and create a NetRestore image from the newly installed (and still un-configured) volume. If you'd prefer to image the volume after it has already been configured, you can proceed with the setup assistant before booting back to the original installation created in step 1.

I performed a clean install, and upgraded to Yosemite. Now iPhoto is gone.

I recently performed a clean install of Yosemite and I am able to install all my old apps expect iPhoto.
It reads, "iPhoto failed to download" "Use the purchases page to try again". Ive ben trying for the past 5 hrs.
I have a good strong internet connection, I am signed in to app store.
This is the only app that will not install.
Please advise

If a partial download is hanging, have a look at the Launchpad. Is there a progress bar below iPhoto?
Then wait and see, if there is any progress. If not, delete iPhoto from the Launchpad:
Hold down on iphoto until it wiggles and you are seeing a cross in the upper left corner.
Click the cross to uninstall.
Restart your Mac to clear the App Store caches.
Reload the App Store "Purchased" page by pressing ⌘R.
Then try to download iPhoto again.
Another problem may be a firewall interfering. Disable Little Snitch or similar.
If all fails, try the download again while running the Mac in Safe Mode. That will disable non-standard extensions. See this, on how to start-up in Safe Mode: Mac OS X: Starting up in Safe Mode

After performing a clean install, is my startup disk correct for apple stock 1TB fusion hard drive? I think I may have to reformat.

After performing a clean install on a stock apple 1TB fusion Hard Drive it appears as things got reversed and showing my startup as not using the SSD portion. The SSD portion of the fusion drive used to be on top in disk utility, now its on the bottom. It also appears that I have to many partitions. Im thinking i need to reformat my Hard Drive again. I can't seem to find any answers.

Performing a Clean Install

I, like many others before me, have noticed some lagginess with the core animations (expose, minimizing, dock magnification) after doing an upgrade installation of leopard. I want to perform a clean install, as people who have done this say that it really helps with this problem and other speed issues in general.
What I would like to do is perform a clean install and then reload all of my documents and applications back onto the disk. What is the best way to go about doing this? I am also interested in freeing up some HD space so it would be nice to not have to do a full restoration.
Would it be unwise to try and selectively restore items back to my drive using time machine? Should I just do a clean install and then a full system time machine restore, or would that just bring back my same speed issues?
I'm just looking for a little insight into what would be the best and safest way to go about a clean install. Thanks a lot!

Use CCC (carbon copy cloner) to clone your system to an external firewire connected hard disk to a partition that is slightly larger than the in use size of your MBP disk.
Verify that you can boot from the clone.
Disconnect the clone disk.
Do an erase and install on your MBP hard disk.
Apply all of the software updates.
Reinstall any purchased applications that you use.
Connect the cloned disk.
Move your data from the clone to the MBP using finder on as as needed basis.
Keep the clone until you are satisfied that you have recovered everything that you need (3 months to a year).

While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?

While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?
Originally I was running Mountain Lion as an UPgrade from Lion. I created a backup in Time Machine, performed a clean install of Mountain Lion, then I proceeded to use Time Machine to restore the back up.
When thinking about the essence of a back up restore, it occurrs to me that for all I know, I may have just wated my time IF Time Machine also restores all the old unneeded files that remain from Lion after an upgrade.
Since the backup was made while running Mountain Lion as an upgrade from Lion, did restoring this backup defeat the purpose of a clean install by reinstalling old Lion files?
If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?

Hello John!
Thank you for your response which solved my problem. For other users who may stumble upon this, I'll clear up the confusion and share how I solved the problem with your help; When looking for answers to my computer problems, finding unresolved questions where person B offers a solution and person A never comes back and says "That worked, thank you.", it demonstrates a "k-thnx-bye" user mentality that leaves others with the same problem lost. Without further ado:
It is not clear what you did because the meaning of "clean install" is vague. You can erase a volume and install an OS which leaves none of its previous content intact,
This is what I did: I erased the volume leaving no previous content intact, while then installing OS X Mountain Lion.
or you can upgrade an existing OS (or reinstall the same one) which does not alter your user - installed files.
An upgrade to Mountain Lion from Lion is what I started with initially before erasing anything. This was undesirable. Since this can cause Macs to run slower (especially whereas I'm using a mid-2011 Mac Mini), my goal was to go from operating within an upgrade to Mountain Lion, to operating within an installation of Montain Lion that was not preceded by any other oprating system.
Hence a "clean install of Mountain Lion while continuing with old apps and files" is confusing.
Well put and understood. What I should have said was:
1.Erase the volume
2.Install Mountain Lion clean
3.Confirm that Mountain Lion is functioning properly
4.Proceed to use either Time Machine or Migration Assistant to Import/Migrate/Copy over only two things; My old apps (That had been stored originally in the designated Applications folder) and all files and folders originally stored in the home folder under users.
If you restore from a Time Machine backup then all modifications that occurred subsequent to that backup become erased. It renders moot any OS X upgrade performed subsequent to that backup.
That makes sense and is just as I later suspected.
If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?
Yes.
This is what I did and everything works perfectly. Thank you so much once again!
