Moving to another drive. Have I got this right?

I hope you guys aren't as mean as your rep! Arch has a reputation for being hard to install. So, I decided that I would install to a USB hard drive and move it if I was successful. Well it wasn't as bad as all that. I have a working system with an xfce desktop and I like it.:) So, time to run my Manjaro installation to a backup drive and move onto my laptop's main drive. I think I know how I want to do it but, I'd like someone to check me. Here are the steps I think I need to do:
Use gparted to backup the existing partitions to another USB drive. That's running now.
Blow away the partitions on the main drive.
Boot from a liveCD and use gparted to resize the partiions on the USB drive as needed and copy them where the partitions used to be on the main drive.
Edit /etc/fstab to mount the right paritions to the right mount points.
Modify grub to boot the arch installation.
I should mention that the windows installation that came with the laptop is still on the main drive and I want to be able to boot into it and I'm not using UEFI. I'm comfortable moving around the partitions and I have editted an fstab before. I'm not so sure about grub...yet. If you have a good link, please let me know. As a last resort, I have a boot rescue disk that can probably handle it. I've used it to straighten out worse but, I'd like to learn how to do it myself.
So, did I miss anything?

I did move successfully...sort of. Some observations and a question.
WonderWoofy you were right. I was going to just move the partitions around with gparted because I could queue up all the operations and go to bed. In the morning viola, everything the way I want it. It didn't quite work out. Gparted got errors copying my /home partition. So, I blew away what it copied, created a new partition, and rsynced the files in my home partition over. That worked fine and I'm sure it was faster than copying the partition would have been.
I got /etc/fstab editted and that worked fine.
Now for the surprise. Grub's not as dumb as it was last time I played with it. It was a while back. It might have even been lilo. I wanted to boot off the install on my USB drive to mess with grub. Forgive me, if you understand grub and this sounds dumb and please help me remedy my ignorance. My bios was set to boot off the USB and there was a grub instance on there. That instance was set to boot me into arch. It looked like it found the arch partition on my main drive and booted into that. It worked though. So, I shut down and unplugged the USB and started back up. A grub menu came up with two arch entries, two windows entries (One's the recover partition that came with the laptop) and two manjaro entries. The ones I want seem to work. I don't know what it'll try to boot if I select a manjaro entry. I'd like to get rid of them though.
I don't see anyplace grub could be detecting manjaro. None of the web pages I can find that address editting that menu seem to speak about the grub setup I'm finding here. Everything I've ever read on grub cautions against editting the grub.cfg directly but, I am tempted. Any suggestions?
EDIT:
Never mind. A more careful reading of the grub archwiki lead me to try this command:
# grub-mkconfig -o /boot/grub/grub.cfg
That did it.

16:9 with miniDV and iMovie - have I got this right?

Hi everyone,
Firstup I have a Sony DCR-TRV33E miniDV camera which I can set to 4:3 (default) or 16:9
From your experience will the camera simply put black lines on top and bottom of the picture? i.e. letterboxed 4:3 video?
Will iMovie assume the input is 16:9 so it will stretch out the letterboxed 4:3 from the camera creating an ultra widescreen and somewhat skewed video?
I know I should just try it out but i'm moving jobs, 2nd baby is due in 2 weeks, etc. etc. simply rather try and learn a bit before I stuff around with it as time is short!
Thanks for all tips!
Cheers
Jason

Gruezi Jason,
From your experience will the camera simply put black lines on top and bottom of the picture? i.e. letterboxed 4:3 video?
There are two ways digital camcorders create 16:9 video:
• simply by cropping (letterboxing) the footage.This goes for most camcorders
• some camcorders have "oversized" CCDs and are thus able to stretch out the footage.
In any case, both methods will result in loss of resolution (especially the first one) as not all the lines are used to display the video. See also Dan Slagle's Unofficial Movie FAQ:
http://www.danslagle.com/mac/iMovie/tips_tricks/6004.shtml
Will iMovie assume the input is 16:9 so it will stretch out the letterboxed 4:3 from the camera creating an ultra widescreen and somewhat skewed video?
When shooting 16:9, the footage will be flagged as widescreen and can thus be recognized by iMovie as such. You'll need to create DV-PAL Widescreen projects to capture your video with the proper aspect ratio.
hope this helps

Interfaces have i got this right?

Hello folks just wondering if i've understood interfaces correctly.
Interfaces are like a contract between user and serviceprovider.
So basicly i could have a Interface Tool
a class Monkey
a class Hammer
a class Ninja just for the sake of it
and the code for Tool would be
interface Tool{
      use();
}and the code for hammer would be
class Hammer implements Tool{
    void use(){
          //bang something
}and the code for Ninja would be
class Ninja implements Tool{
     void use{
           //throw some stars
}and the code for Monkey would be
class Monkey{
     Tool tool1=new Hammer();
     Tool tool2=new Ninja();
     void work(){
          tool1.use();
          tool2.use();
}But what if Tool was a class and Hammer and Ninja extended Tool instead? Then what would be the point of using interfaces?
Edited by: ColacX on Jul 19, 2009 5:40 AM

It's both inheritance/polymorphism. Purely technically, there's hardly a reason for it. But interfaces are much more convenient.
But imagine you want to test a method that takes an instance of type Tool as a parameter. If Tool is just an interface, you can create a basic implementation of it that supports your tests. This doesn't seem like much at first, but if the instantiation of the Tool class depends on several other classes in return, things start to get difficult to "mock". Like a ResultSet for instance - either quick-implement it to do what you need, or set up an entire database just for a unit test.
Another advantage is that everyone who's programming against your API doesn't need to have the current class implementations. Just share the (more stable) interfaces with other teams, and they can program and test, even though your class is still under construction, too. Changes to the class also happen more often than changes to the interface.
And of course, you can only extend from one class, but implement many interfaces.If Ninja already extends AsianWarrior, along with Samurai, you'll have a hard time making extend Tool as well. ;)

Have I Got This Right? (RAM)

Sorry to beat this dead horse, but I've gotten my info about Logic/OS X's use of RAM from different unclear sources, and I just wanted to run my understanding by you guys. How much of the following is true?
1) Because Logic is a 32-Bit application, whether in Tiger or Leopard, it and all its AU plugins share a pool of RAM limited to 4GB, except:
2) EXS24, which can access a separate 4GB per instance.
3) Even if an AU plugin was 64-bit, it would still only have access to a part of Logic's pool of 4GB
3) In Tiger, any application (32-bit or 64-bit) running alongside Logic can access its own additional memory up to 4GB.
4) In Leopard, a 64-bit application can access much more than 4GB, but not Logic, because it is still 32-bit.
THANKS!
Context: trying to figure out what to do about running VSL SE on the same machine as Logic -- 4GB installed. I think I add 4GB and run VSL in Ensemble app?

Running Vienne Ensemble standalone is the way it works. You can even make copies of the VE app and use more than one instance at the same time.
Concerning logics RAM limitation: since VIs like Omnisphere use more and more of RAM this limitation is getting really anoying. I recently had a session where logic started to crash over and over until I found out that logic already had 2,7 gB of RAM assigned. I'm not sure if it's logic or if even leopard isn't really a 64 Bit system. Hopefully we don't have to wait another year until apple is able to provide a real 64 Bit system for his pro customers.

Surround sound mix, have I got this right (CS6).

OK, done some reading and this is what I think I need to do with my 6 WAV files.
Channel 1 Left - Drag dot in surround pannier to top left.
Channel 2 Right - Drag dot in surround pannier to top right.
Channel 3 Centre - Drag dot in surround pannier to top left (and pan Centre percentage to 100%).
Channel 4 Left Surround - Drag dot in surround pannier to bottom left.
Channel 5 Right Surround - Drag dot in surround pannier to bottom right.
Channel 6 LFE - Drag dot in surround pannier centre (and pan LFE to 0gb).
Unless specified LFE and centre percent infinity db and 0%
Does this sound correct?

Channel 6 LFE - Drag dot in surround pannier centre (and pan LFE to 0gb).
If you do this, there will be output on LFE and Front Left/Front Right, but there only should be output in LFE. If you pan Centre to 100% there will be output on LFE and Centre - that's also wrong. I also don't know how to get output ONLY on LFE!
Besides, this is the right order for your Monos:
1: Left
2: Right
3: Left Surround
4: Right Surround
5: Centre
6. LFE

Music not showing up in my Music Library after moving to another drive

My C: drive was full, so I moved the file to my F: drive (have done this before, but somehow it only copied it and reverted to the old location on C).
I found multiple iTunes folders throughout my many drives and got rid of all but the ones on the F: drive. It now shows multiple folders with all my songs on F: drive. However, they do not show up in my Music Library. I've tried the preferences \advanced \general \copy music to library trick and still nothing. Don't think I lost the music since I have all these folders (1 for each artist) and it looks like a lot of bytes.
Please help..
Alternatively, I'd like to know how to get the whole library on my laptop and off of this old computer that ran out of space. The F: drive is detachable.
Thank you in advance

Do you use iTunes Match? Others have complained that it can take some time (overnight?) for items to appear in their library because of Match activities.
Can you play a file with Quicktime Player? Is it complete?
Delete an item from the library but not the actual file. Add the file again.

Want to check if Iv'e got this right: PC External Drive PC Mac

Hi,
I'm going to attempt something and I just want to make sure I'm doing it right (I've searched the forums and this is what I've come up with).
I have an iPod formatted to a Windows XP computer and all my iTunes on that computer.
STEP 1:
I want to move my entire iTunes library off the C drive and onto an external hard drive (I'm out of space on my computer and will erase the library from the C drive once the transfer is done, leaving the library only in the external drive).
I assume this is what I need to do?
http://docs.info.apple.com/article.html?artnum=301748
I've read in the forums that sometimes there are problems with the iPod recognizing/synching to the new drive -- but I'm assuming if I follow the procedures in that tutorial then any problems I have can be fixed (i.e., By transferring in that way I'm NOT doing any permenant damage to my library, filelists, labels, etc.) -- correct?
I just want to check this before I do Step 1.
STEP 2
About 6 months from now I expect to get a new computer, and I expect it to be a Mac. I would want to transfer all my music to the Mac and discard my current PC. There's lots of stuff on the board about doing this. E.g.,
http://docs.info.apple.com/article.html?artnum=93367
My one question now -- which is probably a silly one -- is this: Is the fact that all my music will need to be transferred from my PC's external hard drive (as opposed to the internal C drive) cause any significant additional problems? I think the answer is no but I just want to make sure.
Any clarification you can give on this would be appreciated. Thanks.
iPod Windows XP Pro

Thanks. I've got one related one.
Let's say I copy everything to my external hard drive but -- for the time being -- still leave the original on my c drive. Is there a way to test that the iTunes is working off of the external drive?
In other words, before erasing the songs on the C drive, can I do this and check to see that iTunes works with the external, the iPod interfaces with the external, etc. And then when I'm sure, erase the stuff on the C drive?
If so, how do I go about verifying this?
By the way, all of these songs are in mp3 format.
thanks,

Have I done this right? (Restoring from Time Machine Backup)

This morning I turned on the iMac, it came up with the apple logo and a loading bar, which fills up within about 5-10 minutes and then the computer turns off.
After research apparently this was harddrive problems.
As I have Time Machine Backups I went into Disk Utility, (this was after reading some previous answers to questions) erased Macintosh HD, left disk utility and now have started a full restore of Time Machine Backup of a few days ago - says it will take 4 hours. Have I missed anything? Was I mean't to install a clean version of lion and then make the time machine backup? or have I done it right and gone straight to restoring a time machine backup
Thanks

You've done it right, but you may still have problems. The internal drive has malfunctioned once and may do so again. In that case, you'll have to replace the drive (or less likely, some other component.)

How can I get 10.8 to recognize my home folder that was moved to another drive?

I installed an SSD in my MacBook Pro a while back and replaced the optical drive with a regular SATA hard drive and moved my user folder to the larger drive. Unfortunately, Moutain Lion didn't like that, I can no longer log in to my account (I am assuming the relocated user folder is the problem, perhaps it is not?). Has anyone else encountered this problem?

Are you able to log into the machine with a different account (like an administrator account)? If so, open Directory Utility (/System/Library/CoreServices/Directory Utility.app) and go to the "Directory Editor" tab, and select your user in the list on the left (the one that you moved to the second drive). What is the value for "NFSHomeDirectory" for that user? The upgrade to OS X Mountain Lion could have reset this value (since having home directories on drives other than the boot drive (I think) isn't supported). Have you tried reapplying the procedure you used to move your home folder to the secondary drive prior to the upgrade?

what sort of drive do i have in my macbook?

You have the (LG) HL-DT-ST DVDRW GWA4080MA BE39
It is a superdrive that can burn cds or dvds and dual layer dvds.

I did a hard drive test and got this error code.. what does it mean?

4MEM/4/40000000: 0x6a494c18

You did the Apple Hardware Test (not "hard drive test"), I presume? That error suggests RAM.
You can do the extended AHT for more, or try downloading and running Rember:

Tell me if I've got this right ...

I'm going to create a J2EE web application driven against an Oracle database. I want to confirm my approach for development to ensure I'm not on the wrong track so please help me make sure I understand this correctly.
I'm creating a JSP page with a form that posts to a Servlet, the Servlet pulls the form data out and makes a call to the database based upon it, the returned result is being stored inside of a CachedRowSet which is then pushed into the Response scope, I then redirect users to another JSP from the Servlet, the JSP then pulls the CachedRowSet from the Response scope and renders the results using this CachedRowSet bean.
Is this proper?

Is this proper?Yes it is proper, and in fact it's what a lot of web architects are recommending these days. As some other posts have said, if you are writing a small system you can get away with servlets only, or JSPs only, but for something professional (I see you are using Oracle) an MVC design like your description would be better.
Personally I don't care much for JSPs because once "they" decide to change the look-and-feel of your website, there's a lot of repetitive work necessary to do that change. Unless you have planned for that possibility. But I haven't come up with anything much better.

Moving to another drive. Have I got this right?
