Can someone explain how .prel files work?

Can someone explain how .prel files work? My C drive is O/S and programs, my D drive is storage and the project file(s) (the .prel file) are on my E drive.
How is this supposed to be more efficient/faster? P.E. (C drive) has to constantly communicate back and forth across drives with the .prel file and all the files in the subfolders? It seems like it would be slower.
As I mentioned in a previous post; my zooms in/out of the Timeline are VERY slow. It is almost 1 second before the Timeline gets bigger/smaller. Any info would be great,thanks!

By using multiple HDD's, one is spreading the I/O (Input/Output) load over various HDD's. The controller is faster than a single HDD, being tasked to read/write from/to multiple places. One of the first laws of physics is that an object cannot be in more than one place, at the same time. The heads on a HDD are no different. If requests for multiple reads are made, the heads will position themselves over on place on the platters, read, and then move to the next requested location, and so on. However, with multiple HDD's, and a good, fast controller, the heads of each HDD will be placed, where necessary, so reads are done at once, from multiple locations.
For ultimate performance, a good setup would be as follows:
C:\ system OS and programs (more reading being done here, than writing)
D:\ Project files (PREL's in this case)
E:\ RAID 0 Scratch Disks for Media Cache, but not Render files (both reading and writing)
F:\ RAID 0 Media files (more reading, but also writing)
G:\ RAID 0 Export/Share and Render files
Some go so far as to separate out Audio Assets from Video Assets, and use a separate RAID 0 for each
The downside of that "ultimate performance" setup, is that when a Project is completed, to clean up, one has to go to many HDD's, and locations. There can also be issues when Archiving a Project, because things are scattered about.
I get "good performance" by having my Project, Copies of my Assets and all Scratch Disks on one HDD. What I give up in performance, I make up for with housekeeping chores, when the Project is done. I still spread my OS/programs from my Projects, with separate physical HDD's.
Good luck, and hope that this helps,
Hunt
PS - Above, I mention RAID 0, but even greater speed can be achieved via many HDD's in the Array, and perhaps a RAID 50. RAID 0 is just two physical HDD's. Also, for RAID, I recommend a dedicated RAID controller card, and NOT software, or the MoBo's RAID capability.

HT5463 In my opinion, when the Silence setting is "only when the device is locked", it contradicts the settings you set above, like Manual. Can someone explain how these settings work together?

Can someone explain how these settings work together? Manual seams to contraduct the SILENCE setting at the bottom of the Do Not Disturb page. It's very confusing.

You should have seen information in the support document that you linked from. It used to be with the first version of Do Not Disturb that it would only function when the device was locked. That changed with iOS 7, and not it can be active all of the time. With it on Manual, it is on, but if you have the device "awake" that you can still receive calls/texts, etc. Sort of like you have the phone awake, so it isn't a problem for you to receive things. If you set the settings for Always, this means you can be doing things on the phone and not be disturbed by anything else. Does that make sense?

Can someone explain how "Hybrid Power" works on the GT70?

I have had my GT70 20C for a couple months now and have yet to see Hybrid Power working once. I have been playing games that are clearly taxing my system to the max (SC Blacklist and Rome 2) but the Hybrid Power monitor always says "OFF".
Am i missing something obvious? I've tried searching the forums and Internet and it seems others are having the same issue, but i'm having trouble tracking down an answer.
It is my understanding that Hybrid Power only kicks in when it needs too, but it doesn't seem to be doing that at all.
Is there a way to force it on?
Can anyone shed some light on how this feature is supposed to work?
cheers,
-deluxxe

same question same computer. Hybrid power is a application but it already runs hidden on your laptop. I always play on my laptop with the charger connected. never on battery. I get about 40-80 frames on ultra on bf3 without the AA or Sync. One day I forgot to check if the outlet was on, and I noticed that my laptop was "struggling" to run the same setting I always run. I quickly checked if I was in "gaming" mode for the G settings and the windows 8 battery settings. I was and started getting worried that something happened to my laptops GPU. I started checking what was running on task manager, using cc cleaner to see and new start-up programs running, checked to see if the disk was in use or if that automatic maintenance was occurring since I have everything always running smooth. nothing was running expect the normal. I then realized that I was running on battery. I remembered that this hybrid energy thing only worked on if you have it plugged in and charging because somewhere I read said that the battery wouldn't be able to "Boost" the gpu or overclock or whatever they want to call it. Running on battery wont boost the gpu because theres not enough watts going in. While charging it will boost the gpu. im not sure wether this is the case that it does overclock the gpu because it clearly says cpu on the hybrid application. And once you go on gaming mode the gigherts gets locked to 3.3 on the cpu speed. its all confusing to me and im still trying to figure it out but all I know for sure is that you will gain a very big boost on ur speed or performance on ur gpu when you have it connected to the charger and charging. I tested it out by unplugging and pluging while play minecraft with a shaders mod(which really takes up a lot of GPU) and bf3 and arma. and yes, when on battery u have to lower ur settings to getting decent frames, while charging or plugged in you get to pretty much maximize your settings. I went from 60 frames on arma3 to 20-30 frames on battery. how sad that you must always be connected to get that good boost and fps. im not sure wether this is a good since only msi does this and it really its overclocking your gpu, or if 770m is always runs that good and msi just saves you battery when gaming on battery. im not sure but if it really is helping out my gaming then that hybrid power is really good becausae that boost in frames is like a never go back type of thing. always game with turbo fan on and plugged in and charging

} ///:~
This code is From Bruce Eckel's "thinking in Java"
Here is what I understand and what I don't
At a certain point during the execution of the while loop (in the method main), the garbage collector kicks in and will call the method finalize() -
I am at a loss as to what happens afterwards -
Do the chairs continue to get created (which means the variable i keeps incrementing) and the finalize method keep getting called (which means finalized keeps incrementing) till the system realizes it is really low on memory and starts reclaiming memory ie i now starts decrementing ?
What I would like to know is the exact flow or execution of the code after the garbage collector starts kicking in ie. what happens to the variables "i" (does it increment and then decrement), "created" (does it keep incrementing ), "finalized" (does it keep incrementing) and when is the if i==47{ } statement within finalize() get executed.
There is no part of the code where i is being decremented (so I am guessing that it is the garbage collector reclaiming object memory that must be decrementing it).
I am really confused -unfortunately there's very little in the book that really explains the flow of execution after the garbage collector kicks in and finalize() is called.
Any help would be greatly appreciated

Nice example, but Bruce chose some suboptimal names, I think.
"i" can be thought of as the "ID" of a given Chair (note that it is not static). It is neither incremented nor decremented - it's just assigned from "created". This lets us identify specific chairs (like, say, "Chair #47").
"created" is a running total of the number of times the Chair constructor has been called.
"finalized" is a running total of the number of Chairs that have been finalized.
The process starts creating Chairs as fast as it can. Eventually, memory gets low, and gc() starts collecting Chairs. While that's happening, chairs are still being created in the main Thread. So "created" and "finalized" may both be incrementing at the same time.
When gc() picks Chair#47, the finalizer code sets a flag that causes new Chairs to stop being created. This causes the program to fall out of the while() loop, and the program spits out its data and exits.
On my machine, the program created 29,542 chairs before exiting.
Remember - often, gc() runs only when/if the JVM decides it's running low on memory. Specifics depend on the JVM and the startup options you use - some JVMs are very, very clever about doing incremental garbage-collection these days.
Does that make more sense?

I posted in this thread an example that illustrates how to use the 3d graph to do surfaces ac lines.
The type of data that you present to the 3d graph depends on which mthod you are using. In general you want to present a set of points that need plotted. These points are defined by taking one value for each of the XYZ and sometimes W arrays.
Explanation:
You want to plot a surface that is defined by four point (X0,Y0,Z0,W0), (X1,Y1,Z1,W1), etc. You can present the values using (4) 2-d arrays each of which have four values at index (o,o), (0,1), (1,0) and (1,1).
Thie first point plotted would be the point that is defined by taking (0,0) from each of the arrays.
So as you can see from the above all of your arrays should be of the same size and dimensions for this to work.
Look at the Example i posted in the other thread and try some small experiments with small data sets before you jump to anything complicated.
I hope that helps,

Please can someone explain how to delete email addresses? I have people who when I type in their name it comes up with the correct email address but then when you hit return to confirm it promptly changes the name to someone else (always the same someone

Please can someone explain how to delete and email address that when typed in brings up one name but when you hit return to confirm it jumps to another name. I can't find them in my contacts list but they do come up when you type the first few letters of a name.
EG If I type xyz and the name of the person comes up, when I press return to confirm that's the one I want then it jumps to [email protected], always the same def address.
I can't fathom it out.
Thanks
Terri

Try this:
Start a new email. In the To address bar, type in xyz like you normally do, press return to confim, and when the address you want to remove shows up in the address bar, move your cursor over the address you want to delete.
A small triangle next to the name will show up. click on it, a drop down menu will open, click Remove from Previous Recipients List. Then do the drop down menu again and Remove Address.
Good luck.

Can someone explain how to set up an administrator account so that I can have my phone and my daughters have separate apple ids?

I mistakenly updated to the latest version of iOS and ever since then I can send messages to my daughter and I receive them but she does not. She has an iphone also and her phone is under my apple id also. Someone told me that I could set up an Administrator Account so that she can still be under my account but she has her own ID and that will fix the problem with text/imessages. I can't find anything on the website that explains how to do that. Can someone explain that to me?
Thanks!

I'm still not clear on what you are trying to accomplish. If you have an iPhone and she does as well you should have your own Apple IDs.
If you want to pay for any purchases she makes with her phone as far as apps/music goes than that is what Family sharing is for.
In my case my Wife and I are setup for family sharing. When she purchases music/apps it charges my credit card. This setup also allows me to share my past music/app purchases with her and vice versa.

Can someone explain how data is fed to the usage details screen in My Verizon?

Can someone explain to me how I can view my data usage for a past date today and when I look at the same date a few days from now there will be additional data. Customer support were adamant that the data usage details come directly from my device so I commented that my device must be saving usage and sending it to Verizon arbitrarily to which I was met with silence on the line.
Here's an example - on 4/1 I checked my data usage details for the date of 3/21 and it looked like this:
03/21/12
08:43:00 PM
0.02518
03/21/12
09:17:00 AM
0.01475
03/21/12
07:20:00 AM
0.01730
then on 4/7 when I checked my data usage details for the date 3/21 it looked like this:
03/21/12
11:45:00 PM
1.15382
03/21/12
11:38:00 PM
0.24853
03/21/12
08:43:00 PM
0.02518
03/21/12
07:50:00 PM
1.03191
03/21/12
06:55:00 PM
1.18499
03/21/12
06:10:00 PM
1.03968
03/21/12
09:17:00 AM
0.01475
03/21/12
07:20:00 AM
0.01730
The red rows have been added between 4/1 & 4/7, but where did they come from? This is just one example, it's happening all over my bill and Verizon cannot justify the anomaly and certainly won't consider removing the $40 in overage charges I have this month. Which brings up another question, why doesn't Verizon offer more than 10GB for the mifi? If I want to use more data and am willing to pay for it, I have to go to another provider?

Hi kellieh,
When you had your data overage (and the additional spurious charges), how did Verizon respond to you?
I have just reported a 2x discrepancy between individual device data usage (.89 GB total) and the reported 1.5 GB for my account. They claim it will take 72 hours to get back to me after they research the problem.
What avenues did you pursue to make contact?
I caled 611, then emailed tech support, then sent a private message to Verizon Wireless support.

Can someone explain how the visit count works? Why would it say I visited a site over 600 times? Anyone know how this counts these visits?

On top of all this, I can't even find out how to file a complaint with anyone higher up than Customer Service.
I hate to tell you this, but you didn't write an email. You wrote a discussion post on the Verizon Wireless Community forum which is a public peer to peer forum. Unfortunately since you didn't mark your post as a question, the VZW reps that roam this community won't ever see your post. Before you re-post it, don't. Duplicate posts get removed from the community.
I see there were several missteps both by the reps and yourself in your post. First you should have insisted on returning the phone within the 14 day return policy period. Second which Samsung Galaxy mini model did you purchase? The S3 mini or the S4 mini? Did you do any research prior to deciding on this device. The reps at that time deflected the easiest course of action, by trying to get you to replace the phone under insurance instead of returning the phone. The Early Edge payment option requires the current phone on the line using the early Edge must be returned to Verizon Wireless. Did you once considered going to a third party site like Swappa to purchase a gently used device for your daughter?

Can someone explain how a Thread actually works

Can somebody explain to me how a Thread actually works. How can the the run() method be called by the start() method? It doesn´t make sense to me.

Well, all Java code is just methods calling other methods. I don't see what the confusion is. You create a Thread instance, give it a Runnable, and when you call start() on the thread, it calls run() on that Runnable.

Can Someone Explain How Xorg Works Like This?

My friend uses Ubuntu, and this is his xorg.conf .
# xorg.conf (X.Org X Window System server configuration file)
# This file was generated by dexconf, the Debian X Configuration tool, using

# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg
Section "Device"
Identifier "Configured Video Device"
EndSection
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection
I know it says
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
but still. Can someone enlighten me?

I may be missing something but it seems that your friend doesn't need an xorg.conf at all (if that xorg.conf works for him). In fact, until the recent Xorg upgrade, my desktop didn't need an xorg.conf either. What, exactly, is the cause of your bewilderment?

I am trying to use an external HD and need to configure it for the MAC. Can someone explain how to configure the HD (Western Digital - My Passport SE)?

Can someone help explain how to add an external HD to the Mac? I have a Western Digital My Passport SE and need to configure if for the MAC and add it to the HD location on my Mac.

Connect the external drive to the Mac. You can do that while the Mac is on, (If the drive is one that has to be plugged into a wall outlet do that too and turn the power on.) If there is a light on the drive it should turn on.
Now double click on the hard drive icon - top left of the screen of your computer. When it opens look for the Applications folder. Double click that. Next look for a folder called Utilities. Double click. In there you will see a file called Disk Utility.app. Double click on that.
You will now see something like this, with two items on the left. The second one is your new drive.
Select it - one click. And click on Erase - one of the buttons at the top, You will see this.
You must select the Format, it's a drop down - the one shown in the image above is best. You can change the name from Untitled if you want. The name can be changed later if you prefer.
At this point look at the bottom right. There is a button there called Erase. Click on it. Then go get yourself a cup of coffee - this will take a few minutes.

Can anyone explain how Exchange Push works?

I was wondering if anyone could explain how the exchange server push is working. We recently picked up an iPhone to test with our small business and we noticed that it states it is using push information for exchange.
However all of our other phones (Treos w/ WM 5 & 6) aren't exchange push, they instead have to sync. The members who have Blackberrys have push, but those apparently get the push because of the license server we had to purchase for the Blackberrys.
Any info would be great to provide to some of our staff.

If you google about you can find lots of details, but some key points i don't see mentioned is that Exchange Push requires web access. Basically you need web server running a front end to Exchange. The first iteration of ActiveSync for WindowsMobile worked by using the Outlook Web Access client. The phone would connect using HTTP/HTTPS and look for updates - this was triggered by an SMS message and referred to as AUTD (WM5 works this way generally). When Push came out, it required SP2 on Exchange 2003 and WM6 or WM5 with a special patch. Now the phone maintains a heartbeat connection with the Exchange server - it still does this over ports 80 or 443 (think HTTP/HTTPS).
The web server part can be a separate server from Exchange but it all has to be set up to work together. Also firewalls require some tweaking to allow the heartbeat connections to stay active. If you have Exchange and Outlook Web Access then you can usually get Push to work (there some ways to lock it down and stop in in newer versions of Exchange) and the beauty is you don't need extra software as is the case of Blackberries where your company must buy a license for Blackberry Enterprise server.
So your BBs sync because your company bought a BES server license. Your WM5 devices syn manually because you are probably not running Exchange2003SP2.
Hope this helps.

Can someone explain how to assign tracks....

First off.. I'm loving GarageBand. Love to send my stuff somewhere.. not sure where.. let me know if you know..
ANYHOO....
one thing I'm running into is assigning tracks.
Ch 1, 2, 3, 4 (mono), Ch 1%2, 3&4...
Here's a common scenario at my iMac.
Track 1. Turns on monitor. Plays. Nothing. huh? Assigns to ch 1. Works. changes to ch 2. doesn't work. changes to ch 3&4 doesn't work.
Hmm.
Finally gets it working.
Track 2. Does roughly the same thing. Doesn't work. Ok.. select another channel. works.
Adds track. wait, now my vocals are on this channel and not the original channel.
Basically, a whole dose of confusion.
Can someone describe to me why/when I would use Channel 1&2 and ch 3&4 as opposed to 1, 2, 3, 4 independently?
Can someone also tell me why when I have two tracks, one assigned to 1 mono and one assigned to 3 mono they don't both work? Shouldn't they work?
Also, seeing as I think the 1&2, and 3&4 options relate to those independent channels (1, 2, 3, 4) how do you record three or 4 instruments at a time? Where's the 5, 6, 7, 8 channels? I know you can record up to 8 tracks at a time no?
Thanks!
Jay

Sorry Hangtime.....
If I understand your comment correctly, I think the answer is my audio interface tool . It only has two inputs. Of course I'd need more inputs if I wanted to record more tracks in unison, but even now, when trying to record vocals on channel one and guitar on channel 2, or 3 it doesn't seem as though they both are recognized. The tracks are there but one of the tracks won't register any input. I end up playing around with assigning different channels to the tracks until both tracks are registering input levels but it's always a crap shoot it seems. there doesn't seem to be a consistent rhyme to it.
So there's that.
There's also the when/why you use the stereo channels as opposed to the mono channel and how exactly do they relate... i.e how does ch 1&2 relate to ch 1 (mono) and ch 2 (mono)?
Thanks!
Jay
