Are the FW 800 and 400 on different buses?
On the MBP are the firewire 400 and 800 ports on different buses or do they share one? So if I have an external drive in my 800 port and a camera in the 400 port are they separate or should I buy a firewire expansion expresscard? Thanx!
ok, i think we may be talking about different busses here... the firewire controller resides on the PCI buss.
the PCI buss (usually) has 133 MB/s bandwidth. (someone please confirm... not sure if 33bit, 64bit, and what clock frequency this is)
FW 400 is less than 30 MB/s in practice.
FW 800 is less than 70 MB/s in practice.
even if both "firewire busses" are running at their theoretic maximum data rates, they will not saturate the PCI buss bandwidth.
i do believe that there must be some advantage to using an adapter card, 1, because it would allow a dedicated buss and there must be some processing overhead with operating the devices on the same PCI buss and 2, because it would be on a PCI-e channel versus PCI, however, I don't think that the performance difference will be significant (versus cost and convenience of not having to deal with a card / ease of connections, battery life, etc...) and with anything related to bandwidth, there is no good and better... it either works for your requirements or it doesn't. you need upstream data from an audio device and downstream to a hard drive? figure out the channel count / KBps and determine if you come at all close to the limitation of the exisitng FW buss speeds.

How are the Apps Store and iTunes store different? Which do you use for what?
Can you explain the difference between Apps Store and iTunes store? Is Apps a subset of iTunes store? To which store do you go for what?
Apps you buy from the Mac App store can be used on your computer. You use the same Apple ID as the iTunes Store, but that's the only connection.
Apps you buy from the iTunes App Store are written to run on an iOS device (iPhone, iPad or iPod Touch). They won't run on your computer, only on your iDevice. -
Why are the printed image and its borders different than specified on Aperture's Print window
Hi,
I am trying to print an 11.98x17.97 image on a 13x19 sheet. I specify .51" borders top and bottom, and .52" right and left.
Instead, I am getting a 7.5x10.75" printed image with L 1 1/8" + R 7 1/8" borders and T 1/8" + B 5 3/8" borders. In short, a smaller image, shoved up and left on the sheet. Please see screen shot below.
Same happened when I tried to print a 4x6 image on an 8.5x11 sheet, until I was told by Kirby to enter the sheet size as a standard 'letter size' sheet instead of entering a custom 8.5x11" size. Is this the same? If so, what's the 'standard' size for 13"x19"?
Something is going over my head here . HELP!
RAPHAELFor the Epson 3880, I use the Paper Size "Super A3 / B 13 x 19 in (Manual — Rear)" when using Epson's 13x19" Hot Press or Cold Press paper.
That's from my response to you on November 16th. .
That should allow you to print as you want. I have a hunch about what might be happening with your current print setting, but I want to check it before speculating aloud. -
Mixing Firewire 800 and 400 on an iMac?
I have 2 external FW 400 drives on my late 2011 iMac. I use an 800 to 400 adapter. I've been thinking of getting a new external drive from OWC. The have both 400 and 800. The 800 case has 2 800 connectors and one 400. Does it make sense to mix? Will they all run at the slowest in the chain?
I was thinking of connecting the 800 directly to the iMac using the built-in 800 connection. Then chaining from there using the 400 connection to the other existing 400 external drives. Will I actually get 800 speed on the first drive?
ThanksI have a mixed group of external drives, and just bought a new OWC Mercury quad interface drive.
The user manual that came with it says:
Note: If you are using FireWire 800 and add a FireWire 400 device to the chain, all devices will be reduced to FireWire 400 performance
I tested this myself, which confirmed it. I set up the following chain, with the first 2 drives connected by FW800, and with a FW400 drive either connected or not connected at the end:
HD ----800-----DRIVE1------800------DRIVE2-------400-------DRIVE3
I booted from my HD and timed the copying of a large file from DRIVE1 to DRIVE2. Although the FW400 drive was at the end of the chain and was never involved in the copying, just having it attached immediately reduced the speed of the file copy from Drive1 to Drive2. The actual speed reduction in practice was about 40%, not 50%. -
Can't do factory restore & only disks that keep ejecting are the osx install and apps disks
First of all let me say, this is my first Apple computer and I'm not experienced in forums. Please do not read rudeness into what is actually frustration at searching forever for a solution and trying not to wish I had been talked into an Apple. With that said....
I've had my iMac for about a year and a half. We had lost our internet and were using a hotspot for awhile so we could look for another provider and get online if we needed to. One day I signed on and, we didn't have an isp mind you, but the browser opened up to the dominant isp in this area saying a virus was detected coming from this iMac address? I thought that was strange and panicked so decided to do what I would on a pc, just restore the whole thing to factory settings. Everything was going smooth, (my updates were at 10.6.8 at the time)... when I restored I was back at 10.6.2. (osx disk) I was doing systems updates and one apparently hung.... when told to restart, I did... but the computer would never boot back up. It would turn on.... go to gray screen... then blue screen... then shut off. I couldn't boot in safe mode, pram reset did nothing, smc reset did nothing, couldn't hold 'd' to get to diagnostics, couldn't boot to recovery... it kept spitting out disks after trying to read them... with all those solutions I found online and nothing helping I had to call Apple... they couldn't help over the phone because Apple Care expired, unless I purchased help... this frustrated me because every where I found my problem and a different solution their Apple Care had expired too.... so had to set an appt at an Apple store.
So took it in to Apple, just got it back yesterday. I let them know I was restoring to factory settings so wasn't worried about losing anything. When I picked it up, I was told no charge... it was a software issue they saw where it hung and fixed it. I tried to ask questions about the 'software repair' but they didn't seem to want to answer my questions. It just says 'software repair' on my order. So I asked 'okay, so it's back to factory settings like when I bought it?' I was told yes and I said great that was my goal anyway. I get home and it's NOT like when I first purchased it or like a factory restore. Everything I was doing before it crashed is on there. So I'm back to trying to do a factory restore. But for some reason now, it seems the only disks that keep self ejecting are the osx install and application disks. I still can't do a boot recovery, AHT, or 'c' boot... since the apple disks eject I can't use start up to get to them.
I find it odd that both the oxc install disk and applications disk would be damaged at the same time when they both previously worked. I called the Apple Store where I took it to talk to the geniuses that worked on it because I had a question about the repair they did....
Apple: I'm sorry we don't offer tech support
Me: I understand but I had a question about the repair done from there the other day
Apple: We are just a store and can't answer tech questions
Me: I understand and get that but since I took my mac to your store to be worked on I thought I could ask the person that worked on it a question about the 'software repair' and meaning and what software was repaired
Apple: No you will have to set another apt to bring your computer in if you are still having problems
Me: UGHHHHHH (pulling hair out)
So (a little late huh?) to make a long story short giving what I stated above:
Why is it, only the osx install and application disks not working now? They worked before taking it to Apple
What can I do at this point?
Can you do a factory restore without disks on a Mac?
If by chance both disk did for some reason go out, how do I get them replaced?
If I gave TMI without enough important info let me know.
My OS X install disk says version 10.6.2 on it
About this Mac currently says Mac OS X version 10.6.8
Batteries died on keyboard and mouse so am using usb wired keyboard and mouse
At some point I had used bootcamp and then later found parallels so I could install a Corel product and keep using... could some windows files be messing something up in there somewhere?
It used to say Mac OS X Version 10.6.8 and I could have sworn I saw it said 'snow leopard' in there somewhere, now I can't even find that word in search on the computer. Long post I know but trying to set what was going on at the time I took it in.
I'm not sure what else needs to be added to get this to the correct thread or help. As I stated my goal is to have it like I just pulled it out of the box for the first time so no solution will scare me off about loss of data.
Thanks for any help.Wow, sorry to hear of your experience. Seems strange that your disk would just eject like they did. It could be a lot of things but more than likely you just kind of have to start all over.
What I would do is insert your system disk and instead of going immediately to an install I would go to disk utility and erase the drive. That will erase everything on the disk and give you a new blank disk to start with. After that I would try to reinstall the system. Assuming that goes well then you should be restored to where it was when you purchased it. After that you can reinstall all your applications or personal files. I hope you have good backups.
I remember one time I was having a similar problem and don't ask my why I did it but I actually could not get it to install a system. I removed both of my ram sticks, shut the computer down for about 10 minutes including unplugging it from the wall plug, then reinstalled the ram, plugged it back in and started up from the system disk and all worked just fine. To this day I have no idea if pulling the ram helped but I have never had to do it since and for some dumb reason that solved the problem I was having, which is the same problem you are having now. Call it voodoo but it worked.
Good Luck!!

Why are the threads start and terminate randomly?
Hi there,
I got the program below. I am wondering why are the threads start and terminate randomly? Everytime, I run the program, it produces different results.
I know that these four threads have got same normal priority (should be 5), and under windows there is something called timeslice. Then these four threads rotate using this timeslice. How do we know what exactly the timeslice is in seconds? If the timeslice is fix, then why the results are ramdom?
Thanks in advance!

// Thread.sleep(2000);
} catch (InterruptedException e) {
System.out.println(
"Exception: Thread main interrupted.");
System.out.println(
"Terminating thread: main thread.");
1. Firstly, I set in the main function:
Thread.sleep(10000);
and I run the program it gives:
Thread: 1
Thread: 4
Thread: 2
Thread: 3
Terminating thread: 1
Terminating thread: 3
Terminating thread: 4
Terminating thread: 2

Run it again, it gives:

Terminating thread: 2
Terminating thread: 1
Terminating thread: 3
Terminating thread: 4
Terminating thread: main thread.

And my question was why it outputs like this? It suppose to be:
Thread: 1
Thread: 2
Thread: 3
Thread: 4
Terminating thread: 1
Terminating thread: 2
Terminating thread: 3
Terminating thread: 4
Terminating thread: main thread.
BUILD SUCCESSFUL (total time: 10 seconds)
Why these four threads start and finish randomly each time I run the program? I use Windows, suppose there is a timeslice (i.e. 1 second), these threads have the same priority. Then the threads should start and finish in turn one by one. Am I right?
2. My second question is:
When I change the codes in the 'main' function into:
Thread.sleep(10000); -> Thread.sleep(2000);
it gives me the results like:
Thread: 1
Thread: 4
Thread: 3
Thread: 2
Terminating thread: main thread.
Terminating thread: 1
Terminating thread: 4
Terminating thread: 3
Terminating thread: 2
BUILD SUCCESSFUL (total time: 2 seconds)
Run it again:
Thread: 1
Thread: 2
Thread: 3
Thread: 4
Terminating thread: 3
Terminating thread: main thread.
Terminating thread: 4
Terminating thread: 2
Terminating thread: 1
BUILD SUCCESSFUL (total time: 2 seconds)
I tried several times. The main thread always terminates before or after the first child thread finished.
My question is why it doesn't output something like:
Thread: 1
Thread: 2
Thread: 3
Thread: 4
Terminating thread: 3
Terminating thread: 4
Terminating thread: 2
Terminating thread: main thread.

What are the delta mechanisms and tables used for Lo Extraction & COPA
Hi all
what are the delta mechanisms and tables used for Lo Extraction & COPA.
please explain clealry.
Thanks & Regards,
JamesJames,
Please go through Roberto's weblog :
/people/sap.user72/blog/2005/02/14/logistic-cockpit--when-you-need-more--first-option-enhance-it
Anyways,
As you know LO cockpit consists of different modules(MM, PP, SD, etc)
They are called appl components. Each of them have a number (eg.MM=02) and for each appl comp they might be different Data sources and for each DS they might be different tables. So, unless you be specific we cant tell a specific table for a DS.
coming to the delta mechanisms, there are " direct delta, queqed delta and serialized delta".
Copa is based on the oepration concern. it can be created on " accouting based" or "costing based".

What are the key benefits and limitations of new pricing model of X5-2?
What are the key benefits and limitations of new pricing model that started with X5 version?
1. Elastic Configurations
Size/price hardware by the number of servers; Fixed configs no longer required
Start with 2 Database Servers and 3 Storage Servers. Incrementally add database or storage servers online.
2. Capacity-on-Demand (CoD)
Upon installation, activate 40-100% of the cores per server and reduce software licenses; Applies to Eighth Rack now too
Activate and license more cores when needed; Active cores may not be deactivated
3. OVM and Trusted Partitions
License software on Virtual CPUs within a VM; Ideal for special-purpose DB options
You can mix different combination of options for different DB on one Exadata.
OVM has no License cost; support is included with premier hardware support
Limitation:
At least 40% of usable cores on the machine must be licensed for Oracle software
Cannot use both OVM and CoD to license less than 40% of cores
A server must be virtualized or non-virtualized – not mixed
A RAC cluster can mix virtualized and non-virtualized servers
4. “Flash Drive” License Metric for EF Storage Server Software
$20K/drive; 8 flash drives/EF server vs 12 disk drives/HC server = 33% higher list
Can transfer licenses between Flash Drive (2 licenses/drive) and Disk Drive (1 license/drive) – part # is the same -
What are the output type and Tcodes?+
What are the output type and Tcodes?
hi,
ex-how to config output type.
You will assign output types using Transaction NACE.
Do the follow steps to assign output type
1)Select Application Type V2 which will have description Shipping.
2)Click on Output types button.
3)Go to change mode by pressing Ctrl+F4.
4)Select one output type which already exists
5)Do Copy As(F6)
6)Give your output type against Output Type field.
7)Under General data Tab, Give Program and Form routine and Save the data.
i think it a work of functional guy but at senior level i think it is not a big deal for abaper.
Check the following documentation
In NACE t-codewe have the application for each one. based on the application output type can be defined, based on output type script and print progrma can be defined.
If suppose data can be read from EDI then we should go for condition records.
So whenever we execute the script first composer checks the output type and then execute the program. in program whenever opn form FM will be populate then script will open first. After that again program till another FM will populate if it then script will populate........like it is cycle proces. Composer does all these things and at last it will submit that output to spool.
Go to the Transaction NACE.
choose the related sub module.. like billing or shipping
doubel click on Output Types
Choose the Output Type for which whcih you wanted your script to trigger
Then select the Output Type and double click on Processing Routine
Then go to create new entries--> Select the Medium (1- print output), then enter your Script and Print Program detls --> Save and come out
Now go to the Transaction (for which you have created the output type)... Issue output--> Select the output type --> Print....
Device Types for SAP Output Devices (Detail Information)
Definition
The device type indicates the type of printer to be addressed. When you define an output device, choose the name of the device type that was defined in the SAP System for your printer model, such as Post2 for a PostScript printer. In the case of frontend printing under Microsoft Windows, you can also use the generic (device-independent) device type SWIN.
The system uses the information in the device type to convert a document from the internal SAP character representation (spool request in OTF or in text format) to a device-specific, print-ready data stream (output request). Since a device type specifies attributes that apply to all devices of a certain model, it can be shared among device definitions. For example, all devices in the SAP spool system that are compatible with Hewlett-Packard LaserJet IIID printers would use the HPLJIIID device type.
You should not confuse the device type with the printer driver. The device type is the total of all attributes of an output device that the SAP System must know to control the output device correctly, such as control commands for font selection, page size, character set selection, and so on. These attributes also include the printer driver that SAPscript/Smart Forms (the SAP form processor) should use for this printer. The SAPscript printer driver that is to be used for devices of this type for output formatting is therefore only an attribute that the device type specifies.
How do I choose the correct device type?
In most cases, the SAP System already provides the appropriate device type for the printer type for the printer model that you want to use.
These standard device types are completely defined and need no modification or extension before you use them in device definitions.
You can also download missing device types from the sapserv server. For a current list of the supported device types, see SAP Note 8928 in the SAP Service Marketplace.
Most printers can be controlled using a generic format, such as PostScript. They can be switched to a mode that is compatible with one of the standard printers for which an SAP device type is available. In this case, a supported model is emulated.
Almost all printers are delivered with Microsoft Windows printer drivers. The system can control these printers with the generic (device-independent) device type SWIN. The Microsoft Windows spool system then performs the processing of the print data.
If the specified device types are not available, and generic device types cannot be used, you must create your own device type or edit a copy of an existing device type. We recommend that only those with specialist knowledge of the SAP Spool System and printer driver code do this. For more information, see Defining a New Device Type .
Attributes of a Device Type
A device type is distinguished by the attributes listed below. If you change an existing device type or create a new device type, you must change at least some of these attributes.
Character set: A character set specifies the codes with which characters must be represented in the print-ready output stream (output request). This code replaces the generic SAP characters set that is used internally by the SAP spool system (spool request).
Printer driver: You can specify different printer drivers for printing SAPscript documents and ABAP lists.
Print controls: Print controls represent printer operations, such as boldface or changing the font size. These print control are replaced by printer-specific commands during the creation of the output request from a spool request.
Formats: Formats specify the format supported by the SAP system. The system differentiates between SAPScript formats (DINA4 and LETTER) and ABAP list formats (X_65_132 = 65 rows/132 columns).
Page format: A page format is the interface between a format and SAPscript. It specifies the paper dimensions with which SAPScript can calculate the row and column lengths.
Actions: Actions are output device-specific commands that are required for the implementation of a format. The action printer initialization, for example, can contain a printer command with which the number of rows on a page is defined. There is a set of actions for every format supported by a device type.

My iSight is not working on my Macbook Pro. What are the possible problems and solutions?
My iSight is not working on my Macbook Pro. What are the possible problems and solutions?
Hello Douglas,
Thank you for the details of the issue you are experiencing with the built-in iSight camera on your MacBook Pro. I recommend the following steps for this issue:
Important: Follow these instructions in order. Test the camera between steps to see if the issue is resolved.
Built-in iSight cameras
These steps are for iSight cameras that are built into a computer, such as the iMac G5 (iSight) or later, the MacBook, or MacBook Pro.
See if the issue is application-specific.
Try another application (iSight works with applications like iChat, PhotoBooth, and iMovie HD 6) to see if the iSight camera exhibits the same behavior in all applications. If it only happens in one application, try reinstalling that application.
See if the issue is user-specific.
Test your iSight camera in another user account. If the issue only occurs in one user, the issue would be isolated to user settings.
Find out if the computer recognizes the iSight
Check System Profiler (in the Utilities folder, inside the Applications folder). Under the USB header, check to see if the iSight camera is detected.
Reset SMC or PMU
Reset your computer's SMC or PMU, and then check System Profiler again. (SMC reset instructions for iMac G5 (iSight), Intel-based iMacs; PMU reset instructions for MacBook and MacBook Pro.)
If your built-in iSight camera is still not behaving correctly after trying all these steps, you may need to contact Apple or an Apple-Authorized Service Provider for service.

Samplers do alot of things, what do you need a sampler for?
Korgs remind me of alot of presets and alot of verb and chorus. I guess if you're posting here you already have EXS and want more sounds or more functionality and if the korg thing is true you lean more to sampling/synthesis than instrument recreation (as in you probably aren't going for VSL if the korg caught your ear). Independence looks really cool, it's quite new. Kontakt is demanding and very flexible, both include huge libraries and I know kontakt has tons of great filters, FX, modulation. It also needs a pretty strong update-which is being dealt with after a year or so. -
The ipad won't sync some photos, saying the file can't be read by the ipad, however it will sync some photos taken at the same time which are the same size and file type. Why does it reject some and accept others?
Hi there. I'm having the same problem: my iPad won't import some photos from a folder, saying that they can't be read. They are all JPEGS and some photos taken at the same time have synched fine, but out of a folder with 200 photos, it only lets me synch 37. I'm synching albums created via Photoshop Elements 6, which has worked fine until now.
I've tried deleting all photos and re-synching, and have also deleted the iPod Photo Cache, but it hasn't made a difference.
The iPad auto-updated to the latest version of iTunes, so maybe that's what's causing it?
Any advice gratefully received! -
