How does the iMac handle HD video editing?

Tired of Window PCs, looking to buy an Apple System. I would like to do some video editing but want to make sure I get a powerful enough system from the start. How does the iMac handle HD video editing or should I look a better, faster computer?

I have a mid 2011 iMac, 21 inch 4 GB RAM (the next to bottom iMac), Lion. I run Final Cut Express 4 with no difficulty (at least so far). It is certainly fast enough. My old G5, 7 years old, was also, and the iMac is faster.
As I remember, I heard from someone on the Final Cut Express Discussions that some people might be having difficulty with FCE 4 on Lion, but I am a bit hazy. Its bigger brother, Final Cut Pro, is also available. I suggest that you post on the Final Cut Express or Final Cut Pro Discussion sites. They have many reliable users.

How does the iMac DC 1.83 compare...

How does the iMac DC 1.83 compare to the iMac G5 2.1?
In real world speed.
In real world features. ie: video frame rate, etc...
Any REAL hardware problems pop up yet.
Things like that.
I an most likely to get one soon, and would like to know.
Thanks
-Apple //GS

Thank you for taking the time to reply. I hope that others reply also so we can see how this new computer is next to the two G5 versions it is replacing in a real world way.
I am happy that the DC 1.83 is no sloth when going toe to toe with the G5 version.
Did you port over your software from the older system, and run the programs to see how things ran, or freash install them all?
Again, thanks

How does the EDB handle deleted items and why am I only able to recover some and not all previously deleted emails?

Hello,
I have been unable to locate information regarding how the EDB handles deleted files. I am able to recover deleted emails from the EDB; however, there are numerous emails that I know have been deleted, that were not recovered during the recovery process.
Is this because the EDB dumps deleted emails once it reaches a certain amount of entries? Or is it more likely the deleted items are corrupted and thus not recoverable? Thank you for your time and I look forward to your responses. The
product in question is Microsoft Exchange Server 2007.

Great information from the other posters and one other possible explanation is if the users did a HARD DELETE. More information on this below
Pre-Exchange 2010 Dumpster 1.0 worked as follows;
1. When a user does a normal delete of an item via Outlook or OWA it gets sent to your deleted items folder
2. If the user then empties deleted items folder those items are then marked with the ptagDeletedOnFlag attribute which in essence hides them from the view of the user
3. At this point the user can use the Recover Deleted Items function in Outlook to recover those items as long as the items were NOT purged using the Recover Deleted Items option OR the items have not passed still the deleted item retention period.
NOTE: Every day there is a nightly maintenance process that in short looks through the DB and examines items that have been deleted. Items that have met or exceeded the deleted item retention period are purged from the system and are
completely non-recoverable. More about this at the end of my post.
4. However if the end user were to delete an item from the Inbox or another folder in Outlook by using Shift + Delete aka a Hard Deletion the item is left in its orignal location and gets marked with the ptagDeletedOnFlag attribute which again just
hides it from view.
5. By default you can only use the Recover Deleted Items option on the Delted Items folder. Howeve you can make it so that you can recover hard Deleted items from other folders. More on that here http://support.microsoft.com/kb/246153
5. The problem with this method though IMO is that you have to know where to look and that can be rather time consuming.
6. If you want a more elegant method to resolve this and are open to using 3rd party utilities check out Lucid8's DigiScope.
http://www.lucid8.com/product/digiscope.asp which will allow you to open any offline copy of the DB from a forensic point of view and to solve your specific issue you can either turn on a filter to ONLY
show hard deleted items OR you can search the entire store and all mailboxes for just deleted items and can then view or export them to PST or MSG format. You can download the product and obtain a 30 day demo license which will allow you to find any
hard deleted items, however to view them or export your would need to purchase a license.
NOTE: When a database is backed up or copied it is an "Offline" database and then its offline the data retention period is not an issue because the nightly online maintenance process can only act on a database that is mounted on an
Exchange server. So for this reason if you want to recover the most data possible use offline copies/backups of the DB with a 3rd party utility like DigiScope
NOTE 2: Exchange 2010 and 2013 use Dumpster 2.0 which is an entirely different beast and I will not go into that in this post since its nearly 1AM however DigiScope can expose that information as well
Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline Exchange Mailbox and Public Folder EDB's and Live Exchange Servers or Import/Migrate direct from Offline EDB to Any Production Exchange Server, even cross version i.e. 2003
--> 2007 --> 2010 --> 2013 with Lucid8's

How does the filesystem handle bad blocks?

Let's suppose your hard drive develops a bad sector on it. What happens?
I remember early products where the OS would constantly try to store new files right on top of the bad block, find the file couldn't be written/verified, then would write it elsehere... then the next time it would do the same thing again, expecting the block to "heal" I guess
What happens on MacOS (extended, journaled) if it's writing a file and finds a bad block in freespace? Does the OS know how to "cocoon off" or tag the bad block as bad and not use it?
Now what happens if the bad block develops underneath an active file? What's the recovery pattern? Or is there none - does it just leave the block bad permanently? Is there any way to fix that?

Boot your computer from the DVD that came with it, and use Disk Utility to check the status of the disk. Select the disk and look at the S.M.A.R.T. status at the bottom. If it displays anything other than Verified, then the disk isn't going to last much longer.
Modern hard disks don't develop "bad sectors" that the OS needs to handle. The disk drive itself automatically remaps bad sectors to spare unused sectors in a way that is transparent to the OS. When too many of those bad sectors are remapped, the S.M.A.R.T. status will report an error.
What you're describing is a failing disk. It's more than likely the early stages of a total failure, rather than just a bunch of bad sectors. Same thing happened to my MacBook a few months ago. After about two hours, it failed completely. I picked up a new drive on the way home, and restored it from Time Machine overnight. The only data that I lost was an iTunes purchase that I made that morning (iTunes Support let me download it again). You have a backup, right?
It's also possible that you've either run out of free space on the startup disk, or you have a process running that's consuming too much CPU and/or RAM resources. If that's the case, a reboot will clear it (until whatever caused it happens again).

How does the JVM handle private class parameters in a utility class?

If I have a class that is public and not labeled as static, but it's constructor is private so that it cannot be instantiated, and all of its parameters and methods are both private and static. The methods modify the private parameters. In this case, the code explicitly is avoiding a singleton pattern, so there isn't even a class being instantiated, so this is a true utility class.
However, the static methods are accessible from multiple objects, and as far as I can tell, the JVM is persisting the parameters in memory beyond the specific thread that called the static method to begin with.
The question I have is how the JVM handles this? Are these private parameters assigned memory and are indeed persisted independent of thread, since there is no class reference. I am working with byte code injection, and the assumption is that a direct reference to a static parameter is much faster to call than having to go through an object reference. Of course, from a programmer point of view, I much prefer the singleton pattern since I am so used to hang my hat on a class reference.
Thanks.

Are these private parameters assigned memory and are indeed persisted independent of thread, since there is no class reference. There is a class reference. It refers to the class, and is obtainable via the class literal; e.g., MyClass.class.

How does the ASA handle Host Headers for a webserver

If I have an IIS webserver with multiple private IP address, and a site assigned to each of these private IPs. I have defined all internal private IPs in the ASA and now I want to map 1 public IP to all sites on these different private IP's but need to use port 80, is this possible?

I know this is a old thread and maybe no one is watching it anymore but I'm going to be dealing with a similar situation and trying to sort it out. All my past experience is with non-Cisco products so I a not familiar with ASA (yet).
In the original question here I think it is complicated by having multiple private IPs on the *same* web server. This should not really be. Since it is one server it can do fine with multple sites all runing on the same port 80 and the same IP# as long as they are separated via Host Headers. If this were done then the question to me would be "Does the ASA retain the hostHeader when it passed the traffic back to the web server?" If the answer to that is "Yes" then the problem is solved. The ASA does not need to "care" about individual web sites,...all it has to do is take whatever comes in on the Public IP on port 80 and send it back the the Web server on port 80 at whatever Single IP# it is (should be) running and then the Web Server software "sorts it out" and picks the correct web site to feed it to.
Would this be a correct way to look at it?

How does the exception handling work ?

Hello,
the reason why I ask this is the following behaviour:
I declared a customized DCErrorHandlerImpl in my application. Here I'm able to see some exceptions but not all, e.g.the following:
In the constructor of a managed bean I entered a statement to create an exception:
int i = 1/0;
which will cause an arithmetic exception of course, when the managed bean would be created (which is not based on the exception).
But I don't get this exception in my customized DCErrorHandlerImpl. Why not ? Where can I find more about how all this fits together?
Many thanks in advance.
Best regards
Martin

DCErrorHandler (as the "DC" part of the name implies) only handles exceptions from the binding layer (aka Data Controls). [url http://docs.oracle.com/cd/E17904_01/apirefs.1111/e10653/oracle/adf/model/binding/DCErrorHandlerImpl.html]The javadocs say this:
This handler caches the exception in the bindingContainer and then...JOhn

Garageband/photoshop users: how does the MBP handle them well?

since these are important apps for me before i buy
can any of you pros tell me how its handling
complex songs/photo files, RAW imaging and the like.
im sure im not the only one interested in this area.
is it faster and more powerful than its predecessors?
thanks
gl

Garageband will be fine, since it's already Intel Native. Photoshop however is not and will run under Rosetta. If you are a heavy photoshop user you will notice the speed difference.

How does the jvm handle drawing images outside an applet window?

I have a question about an applet I want to optimize.
Essentially the applet allows the user to scroll through a large map while viewing only a small portion of the map through the applet window.
The map has a large array of circles with coordinates on the map that are drawn in their appropriate place in the applet window when the user scrolls the map.
As it stands, the paint method loops through every circle in the array to draw them, but most of them are not visible in the window and end up getting drawn in a negative coordinate or a very large coordinate.
My question is are these circles that are not seen in the applet window but are still calling drawCircle in the paint method putting a strain on the computer's graphics card?
Would it be better if I looped through all circles and only called the drawCircle method on circles whose coordinates would be visible? Or would the extra step of checking each circle's coordinates before drawing be not worth as efficient?
Any help would be appreciated.

If the amount of stuff being rendered outside of the clip rectangle is small then it's usually not worth it to attempt to figure out what's being clipped and not draw it. If the clip rectangle represents only a small portion of the entire canvas that can be drawn, however, it's usually worthwhile to put in some logic to only draw what is necessary.
Take JTextArea, for example. It could be displaying a text document thousands of lines long. Instead of rendering every line of text on every repaint operation, it contains the following logic:
1. Get the current clip bounds (i.e. what part of the text area is "dirty" and must be repainted).
2. Figure out what lines are displayed in the clip bounds. Some lines may be only partially visible (a line "halfway" scrolled down), but they need to be repainted too. If word wrap is disabled this is a very quick and cheap operation, but if word wrap is enabled, it's a little more complex.
3. Only repaint those lines.
This way, in the best-case scenario JTextArea only repaints a single line (the line the user is typing in). Worst case, it repaints the number of lines that can fit on the screen. But it never repaints too much.
Anyway, I guess my advice would be: If it's cheap and easy to determine if something is out of the clip bounds, do it. If it's difficult to determine, do it only if you have a noticeable performance issue in your rendering code.

How does the SDK and Reader handle printing with orientation?

I have a document that I want to print, and it contains a portrait page on Page 1, and a landscape page on Page 2. Acrobat Reader correctly prints these pages (with a single print job), and I'm assuming it's because of the auto-rotate option on the print dialog. Is this a feature of Reader, the API, or how the printer handles the request. I've tried printing this PDF just using the JAva API, but the orientation remain portrait for all pages. How does the Adobe Acrobat API deal with mixed orientation pages? Ignore the fact that I did my test printing with Java, because my question is whether or not the auto orientation is a feature of the UI, the SDK, or the printer (or a combination).

Same as the current Ipod Video or "Classic" there is an option under settings to toggle between original aspect ratio or Full Screen.

How does Media Manager handle Motion Projects within the Sequence being cop

How does Media Manager handle Motion Projects within the Sequence being copied?
I've highlighted my sequence, opened Media Manager, and copied it to another drive. When I open up the sequence in it's new project, the rendered Motion Project plays within my sequence but it won't let me go back into this Motion Project to make changes. I tried starting over. This time I highlighted the actual motion sequence and clip that is created within FCP after sending something to Motion and copied those to the new drive. When I went into the newly created 'media' folder and double clicked on the motion project it launched. It looked liked it was going to play but while my crops moves and borders were there, the filmed material is shown as a freeze frame for the duration of the motion project.
I did this with and without 'including master clips within selection'. Any advice would be appreciated. Thanks.

Is there anyone who knows the answer to this? Thanks.

How does iTunes Genius handle two libraries for the same user?

I've been reading lately about how iTunes Genius should work. To my understanding, one of its basic principles, is absorbing usage data from users in order to create a database consisting of as much information possible. I don't expect a detailed explanation about the algorithms here. I know Apple doesn't share that kind of information (for obvious reasons) and I doubt I'd be able to understand much of it anyway. What I would like to know, though, in general terms, is how does this mechanism handle an instance like mine, where I use my Apple ID on two computers - one at home, another at work. That way, I have all my songs on both computers, so I can listen to them in either location. Obviously, each such library produces different usage data.
Thanks in advance for any information, as I'm quite curious about it.

Dear Fateh,
Thanks for the reply.
The features of this plugin are:
Configurable timeout actions including alert, redirect, and logout
Optional and configurable warning message
Option to keep session alive if user isn’t truly idle. Special thanks to Martin D’Souza for a great idea on how to implement this feature.
But it cannot stop a new session for a user, if there is an active (in my definition apex_workspace_activity_log.seconds_ago<240) session already running for that user.
Regards,
Deepika.
