Questions about an enclosed system, playback

With our proof of concept complete, and development started on a production quality project, there have been a couple of questions that come up again!
One of our potential implementations would go into a closed system. What would we need to for the future having an on location media server that works without connection to the internet? Does this involve developing with the Flash Media Server and recording streams with our own custom applications?
Given the need for a closed system that functions the same as the LiveCycle Collaberation Service (primarily video chat), without access to the internet, what would be the estimated cost of the software required to develop set system? Will any edition of the Flash Media Server support this?
A couple questions on the cost of playback:
What is the estimated cost per playback of a stream? My understanding at the moment is the only cost would come from authentication and the initial handshake. After that is there any more cost involved in synchronizing the files for playback?
Thanks a lot for the service and support,
-Eric

Partitioning External Hard Drive- questions about software & filing system

I just got my macbook and I want to use my older external hard drive to transfer data between the macbook and my PC desktop. I have a Maxtor OneTouch II 300gb with only one partition. I have about 80gb of data already on the Maxtor. So my two questions are . .
1. What is the best software (prefer freeware) to partition my Maxtor and keep the data I already have on it? Or is there a better way?
2. What is the best setup for the filing system for the partitions? NTFS for one and FAT32 for the other or something else? I want to be able to both read & write to the Maxtor from both the PC and Mac. Appreciate any help anyone can throw my way.
Macbook- Black model Mac OS X (10.4.6)

I'm not quite sure of what you mean by:
I would like to avoid
moving all the stuff from the external drive to the
mac, and then having to move it all back onto the
external drive.
But most external drive was formated using fat 32 which theoretically limit to 2 TB and file size limit to 4 GB. Just put a useless file from your pc, and connect your external to your MacBook ,and see if you can copy and or delete that file from your Mac.
You can also check your HD format on PC side by: go to my computer, right click the external HD icon and select properties, and it will shows you the hd was formatted with,...
If you mean you want to format to mac format "on the fly", they might be some utilities for that on Mac side, but I'm not aware of, but why you want to re-format it if the external work for both sides without getting new format, since format that using MAc extended journaled wight result unreadable on your PC side.
Good Luck

Question about a file system storage option for RAC on 10g

Hello everyone,
I am in the beginning of connecting our storage and switches, and building RAC on them but there is a little argument between our specialists.
We have two database servers(10g with OEL 5) to be clustered and two visible disk groups to each of those nodes. So question is can we choose only one disk group as a shared storage leaving the rest one as the redundant copy during database a creation window while installing the database. Because some of us argue that oracle database has a built-in capability to decide on what level of RAID we store our data.
Thank you for your help.

"some of us argue that oracle database has a built-in capability to decide on what level of RAID we store our data".
That statement is not true. Oracle has optional multiplexing for control files, redo logs, and archive logs but this is not enabled by default and Oracle will not automatically enable it. If you want redundancy of tables, indexes, temp, and undo you must provide this because Oracle does not offer it standard or as an option. You can achieve redundancy with RAID at the array level, or host based mirroring (like ASM redundancy groups or Linux mdadm). This can also depend on your file system because, I think, OCFS2 does not support host based mirroring (so you cannot use mdadm or lvm to mirror the storage if you are using OCFS2).
Redundancy is not required, but it is recommended if you are using hard disks because they are prone to failures. You can configure RAID 10 across all disks in the array and present this as one big LUN to the database server. If you have two storage arrays and you want to mirror the data across the two arrays, then present all of the devices as JBOD and use Linux mdadm to create your RAID group.
RAC requires shared storage. Maybe you have a NAS or SAN device, and you will present LUNs to the Oracle database servers. That is no problem. The problem is making those LUNs usable by Oracle RAC. When I used Oracle 10g RAC, I used the Linux raw device facility to manage these LUNs and make them ready for Oracle RAC. However, raw has been desupported. Today I would use either ASM or OCFS2. This has nothing to do with redundancy, this is just because you are using RAC.

Questions about SMP (Strobe Media Playback)

Hi all,
Sorry if I am posting this in a wrong forum. I did not know where else to put this.
I want to know:
Is it a web based player that can be embedded in a web browser or is it a desktop application?
How many domains can SMP be played on?
Does SMP support bandwidth detection?
Regards,
digital mystic

The player supports both standard and advanced delivery methods, including progressive download, RTMP streaming,
RTMP dynamic streaming, HTTP streaming, HTTP dynamic streaming, and live streaming. Flash Media Playback
1.5 and Strobe Media Playback 1.5 also provide support for RTMFP multicast content delivery.
While RTMP(x) streaming are FMS content delivery technologies, the player can also be used with other FMS compatible streaming servers, such as Wowza or Red5.
In the case you do not need the use of FMS streaming functionality, progressive download is always an alternative (what this means is that all you need is a video that can be served by a webserver like apache, nginx, lightypd, etc).
As for how the player can be used, these links are allways a good place to start and get a better idea of what it is all about:

Question about dropping frames during playback

Ok... granted my system hardware is a little outdated but... My system was running 1.5 without any problems... all I did was wipe the hard drive, reinstall the os, install CS4, install the drivers for my blackmagic SD card. But now when I render a project and try to play it back I getting drop frame errors all over the place. My video drives all check out runnning the blackmagic speed tests, I've made sure they are defragged and there is plenty of room... so the only thing I can think of is that there must be some setting in 4 that I am overlooking. I'm just shooting on DV and I chose blackmagic DV for my project settings (al playback is set to BM) and everything seems to be pointing to the video drive... any ideas what I might have missed? I've had a stable edit suite (well as stable as an edit suite can be) for so long I must be a little rusty at all those sneaky little settings.

Glad you got it sorted out, albeit with a reformat. I watched your thread, in hopes that someone could address your issue with another workaround.
As for the display (GUI and also media files), it does seem that CS4 is slower in some aspects, than earlier versions. However, with really top-line gear, most folk do not complain. I'm waiting to upgrade the workstation and the OS, before I upgrade to CS4 myself.

This is a very simple question about multi-channel audio playback

I have an mp4 file that i made and i made it 7.1 surround sound, and i'm pretty sure that this 7.1 surround sound works, as it can be played in VLC. i'm using netstream to load my files now. How do i make it so that flash can playback all 8-channels of sound? I suppose kglad would know the answer

Flash doesn't support multi-channel audio (yet?)

Question about Processors, Operating Systems and TFLOPS

Hi guys, I recently read an article about the power of the PS3 consoles. This is a table that I copied from it, which I don't really undestand. All I can see is that the Mac OSX shows the least number of TFLOPs for both PowerPC and Intel architectures. That doesn't seem to be good. If there's anyone out there who can translate the details into "basic language" I would appreciate it.
OS Type------------Current TFLOPS----Active CPUs---Total CPUs
Windows------------152--------------159564------1625622
Mac OS X/PowerPC------7----------------8737--------95371
Mac OS X/Intel---------9----------------2756----------7272
Linux----------------43---------------25126-------215901
GPU-----------------42-----------------708----------2199
PLAYSTATION®3-----516---------------21062---------22299
==============================================
Total----------------769--------------217953-------1968664
If you are further interested, or the table became unreadable, or both, this is the link to the original article.
Thank you very much in advance.

Yes, you are misinterpreting the data.
What you're looking at is the workload on some distributed computing task like folding@home, right?
What it's telling you is that at the time you checked, Windows computers were contributing 152 TFLOPs (trillions of operations per second), PowerPC-based Macs contributed 7, Intel-based Macs added 9, and 516 from the PS3.
However, you also need to take into account the number of active machines.
Those 152 Windows TFLOPS were the combined output of 159,564 CPUs, for an average of 0.0009525958 TFLOPS/CPU.
By comparison, the 7 PowerPC TFLOPS were from 8737 CPUs, or 0..0008011903 TFLOPS/CPU - not all that much different and statistically insignificant.
The Intel Macs' 9 TFLOPS from 2756 CPUs equates to 0.0032656023 TFLOPS/CPU - significantly higher than either of the other two results.
The PS3 on the other hand contributes 516 TFLOPS from 21062 CPUs, for 0.0244990979 TFLOPS/CPU - an order of magnitude higher still.
I'd take the results with a large pinch of salt, though - is that 7 TFLOPS for the PowerPCs, 6.5, or 7.49? That makes a big difference.
Also, consider that when the PS3 is running the code, that's all its doing. Any other OS is going to be running other applications at the same time.
Don't get me wrong, the Cell processor is certainly pulling its weight, but don't discard the GPU - its 42 TFLOPS come from just 708 CPUs, for an average of 0.0593220338 TFLOPs/CPU - two and a half times that of the PS3.

I have a question about Macbook Pro system preferences...

When I first got my Macbook Pro, I thought it was cool to have my computer "talk" to me when I had notifications. For example, when I have an update available, it will say, "Stephen, updates are available." Or when my battery is low, it will say, "Stephen, you are now running on reserve battery power." I cannot figure out how to turn this feature off. Can anyone help me out?

Question about the ability of Genius Bar to help with outside software...

Hi I wasn't sure where to put this, but here's my question. I'm having a problem with the Sims 2 on my Macbook and I was wondering if I go to the Genius Bar will they be able to help me or are they strictly hands off when it's not a direct Apple product?
Also, I bought an external hard drive in the Apple Store but it's not an Apple branded product. If I'm having a problem with that, can I go to the Apple Store?

If it's a question about the installation, system requirements or compatibility with your MacBook, the Mac Genius can probably help. If you're having some kind of issue while using the Sims 2, you'll probably have to contact .
The same is true with the hard drive. If you need some help getting it connected or even formatted, they can probably help. However, if it's not powering up or you're losing files or some kind of operational issue with the hard drive after it's connected, they'll probably refer you to the manufacturer.
Usually Apple can't support other vendors' products. Someone here may be able to give you some more advice, since none of us work for Apple. There may be someone here who's already had the same issue with the Sims.

Question about operating system

Hello.
I just got lenovo T400. I have question about operating system. I choose OS (Windows XP Professional preinstalled through downgrade rights in Genuine Windows 7 Professional). When I get the laptop, Windows XP is preinstalled but I don’t know how to upgrade to Window 7. Please, tell me the way to upgrade.
Have a nice day

you'd need the disks, and would need to do a fresh install, i.e. you can't just upgrade it. everything will be gone

Don't pm me for help! That's what the forum is for. Also, Google's nicer than me. Ask him.

Question about source system copy for BW

Dear all,
I have a quick question about copying a source system for BW.
We have two clients in the source ERP:
100 Customizing
200 Testing
Our BW is only linked to client 200, so when we now delete client 200 and make a copy from 100 to 200, are we then still able to restore the source system connection so that our extraction will work, or will it fail, as in client 100 I have no BW related (except the cross-client-objects like datasource) information, that can be used for a possible restore of this connection.
What is the procedure in this case?
Thanks,
Andreas

Unfortunately, you will lose your source connection and need to create a new one in R/3. You can use the same source system name in BW, but check the source system connection after the copy (SM59). Also, I would "Restore" the source system (in BW, right-click on Source system in RSA1, and click "Restore") to insure the datasources get replicated from R/3 to BW.
Depending on how much you want your BW and R/3 systems to be in synch, you will need to rebuild all your data providers (cubes/ODS's) from your R/3 system. This means deleting all the data and running the initializations from scratch. At the very least, you will need to rebuild the delta queues.
Curious, if 100 is just for customizing, is there any data in it? Are you just creating a new blank client 200?

A question about item "type and release" of source system creation

Hello expert,
I have a question about item "type and release" of source system creation.
As we know,when we create a web servie source system,there will display a pop-up which includes three items as "logical system","source system"and "type and release".
About the item "type and release",when we push "F4" button,there will be three default selections as below:
"ORA 115     Oracle Applications 11i
TLF 205     Tealeaf 2.05B
XPD 020     SAP xPD".
Who can tell me when and how should I use the three selections.
And also I attempted to input the item by some optional letters except the default three selections and it seems that I can input it freely.
Thank you and Best Regards,
Maggie

Hello DMK,
Thank you very much for your answer.It is very helpful for me.
Can I ask you further about it?
I got that it is a semantic description item.
You said the default selections are set by our basis people.Would you like to tell me how should we creat a new value except the default ones for item "type and release"?Only by inputing the value in the item directly?But you see we canot see the new value item we created by ourself when we push "F4" button next time ,is that ok?Or do we have to ask basis people to define one new value item just like the default seletions before we use it.
Also if possible would you like to describe detail about "This becomes important when you are troubleshooting certain issues especially when RFC connection problems."
Thank you and Best Regards,
Maggie

Hi All, I have question about the iMac operating system. I have the last updated. The problem when I manage the place of the folder windows they are all mixing up. I mean they not on the place where I left them. how to set they stay on the same place? I know there are different possibilities to set.
I tried but it not helped for me. What I can do? How and where can set this they stay on their place?
Thanks.

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Question about Removing Permissions from the System Folder with chmod

Hi
I have a question about the removal of permissions from the System folder (and sub directories and files).
Background
Since installing a new HD, clean install of 10.6, application of updates and moving over backed up user directories I have had several issues with permissions.
I have read several threads on this and using disk warrior and other tools I have been able to fix most of the issues.
The Problem
The issue that remains is a permissions check using Disk Utility keeps reporting
ACL found but not expected on "System".
followed by an extensive list of sub directories and all.
Attempts to repair take hours and the same errors are reported.
Found Solutions
I have read about changing and/or completely removing the ACL from the permissions from the System using two different commands:
sudo chmod -R -N ./System/* ( to remove all ACLs)
or
sudo chmod -R -E ./System/* ( to replace all ACLs )
My Question is ( to the UNIX gurus):
What is the difference between the usage with -E and -R and which is the best approach for a Systems directory and (subordinates)?
Many thanks!!

OK
So I misread on the your instructions about the PW reset, did it, no harm in that. I did also select the options to reset all the permissions for all the accounts and the ACL issues were not resolved. My bad, I forgot to note that.
You do suggest getting and expert opinion but alas these are rather elusive. In most cases the Apple solutions is to do a complete reinstall... I have found that unless you completely wipe a drive and rebuild everything there are often artifacts left behind. Since I have full and redundant back-ups I would rather explore and hack a little instead of a dull old system reinstall. The irony is the system issue I had was it was the result a reinstall and combo update on a new drive. I recognize the risks of entering the realms of the System folders but I am willing to explore knowing full well that I have a path to recovery.
Thanks again for your insights. I come to the forums looking for insights and ideas but not a lecture...
