Why is the MPE so much better when using Vista?

I get more realtime playback using Windows Vista than When using Windows 7 with HDV. I can get better GPU and CPU playback both when using Vista for HDV. Why is that? Im using a GT 240 and it kicks *** with Vista. I use a second LCD TV monitor as an NTSC monitor for the realtime previews. I do get some realtime with Windows 7 but only about half as much as with Vista. Something is better about Vista for HDV clips but Idon't know what. I have done several fresh installs and updates. What gives? Any thoughts.

I have done fresh OS installs and Windows updates. The GT 240 was added the same way. For HDV the Vista OS is better. For AVCHD they are about the same. I think it is a bug. It works better using Windows 7 if I don't output to the LCD TV monitor. Do any of you use HDV and preview on a NTSC monitor?

HT204384 The Sd chip is downloaded onto a desk computer. Then forwarded to my laptop. Why is the sound so much quieter when I play it.

We direct down load our Messages to SD chip in church, it is then downloaded onto a deskcomputer. From there it is sent to my laptop computer. Why is the volume so low? Seemed to be no problem when we used the USB.

Three things you can try:
1. Clean the superdrive with a proprietory CD/DVD lens cleaner that uses tiny brushes.
2. Perform an SMC reset:

Why is the Tick Count function slow when used with a .dll but fine with normal lab view code?

when using the Tick Count millisecond timer with a .dll I've written in C, I'm getting some odd timing issues.
When I code the function I want (I'll explain it below in case it helps) in LV and run it as a subVI, feeding it the Tick count as an argument, the function runs quickly, but not quite as quickly as I would like. When I feed this same subVI just an integer constant rather than the Tick Count, it takes about the same amount of time, maybe a tiny bit more on average.
When I bring in my function from a .dll, however, I start to run into problems. When I feed my function an integer constant, it is much faster than my subVI written in LV. When I feel my .dll the Tick Count, however, it slows down tremendously. I'm including a table with the times below:
             | Clock   |   Constant   |
SubVi:   | 450ms | 465ms       |
.dll         | 4900ms| 75ms         |
This is running the function 100,000 times. The function basically shifts the contents of a 2-dimensional array one place. For this function, it probably won't be a huge deal for me, but I plan on moving some of my other code out of LV and into C to speed it up, so I'd really like to figure this out.
Thanks,

Hi Aaron,
Thanks for posting the code -- that made things a lot clearer for me. I believe I know what's going on here, and the good news is that it's easy to correct! (You shouldn't apologize for this though, as even an experienced LabVIEW programmer could run into a similar situation.) Let me explain...
When you set your Call Library Function Node to run in the UI Thread you're telling LabVIEW that your DLL is not Thread-safe -- this means that under no circumstances should the DLL be called from more than one place at a time. Since LabVIEW itself is inherently multithreaded the way to work with a "thread-unsafe" DLL is to run it in a dedicated thread -- in this case, the UI thread. This safety comes at a price, however, as your program will have to constantly thread-swap to call the DLL and then execute block diagram code. This thread-swapping can come with a performance hit, which is what you're seeing in your application.
The reason your "MSTick fine behavior.vi" works is that it isn't swapping threads with each iteration of the for loop -- same with the "MSTick bad behavior.vi" without the Tick Count function. When you introduce the Tick Count Function in the for loop, LabVIEW now has to swap threads every single iteration -- this is where your performance issues originate. In fact, you could reproduce the same behavior with any function (not just TIck Count) or any DLL. You could even make your "MSTick fine behavior.vi" misbehave by placing a control property node in the for loop. (Property nodes are also executed in the UI thread).
So what's the solution? If your DLL is thread-safe, configure the call library function node to be "reentrant." You should see a pretty drastic reduction in the amount of time it takes your code to execute. In general, you can tell if your DLL is thread-safe when:
The code is thread safe when it does not store any global data, such as global variables, files on disk, and so on.
The code is thread safe when it does not access any hardware. In other words, the code does not contain register-level programming.
The code is thread safe when it does not make any calls to any functions, shared libraries, or drivers that are not thread safe.
The code is thread safe when it uses semaphores or mutexes to protect access to global resources.
The code is thread safe when it is called by only one non-reentrant VI.
There are also a few documents on the website that you may want to take a look at, if you want some more details on this:
Configuring the Call Library Function Node
An Overview of Accessing DLLs or Shared Libraries from LabVIEW
VI Execution Speed
I hope this helps clear-up some confusion -- best of luck with your application!

Using OSX 10.9.4. Why does the Finder Menu bar disappear when using Chrome?

I've used Chrome for a couple years, and all of a sudden the Dock and the Finder Menu bar are not accessible when using Chrome. They are present in every other app, as usual. Please help me to get the Finder Menu and Dock active when using Chrome. Thank you.

Chrome may somehow be set to run in full-screen mode. I don't use Chrome so can't check its settings options, but try hitting ESC when Chrome is doing this and see if you get the menubar and Dock to reappear.

Why cant the controlfile be in sync, when using backup controlfile

hi all,
i understand a few point ...from a dba friend of mine..
you need a resetlog to sync the datafile headers and the controlfiles
1) you need a resetlog when doing incomplete recovery
2) you can recovery completely using a backup controlfile provided you have all the necessary archived logs and online redo logs.
3) but in order not to do resetlog after 2) , you must re-create the controlfile
my questions are
q1) are the following point above true ?
*q2) why cant oracle update the controlfile when recovering using the backup controlfile ? in that case, i do not need to recreate a controlfile , isnt it ?
Rgds,
Noob

hi hermant,

Yes. i am using a backup controlfile, but i have all the archived and online redologs till point of failure ?
The purpose of a resetlog is to sync the controlfile and datafile headers , isnt it ? but i do not need to sync, as i have all the latest applied
am i right ?
If you use RECOVER DATABASE USING BACKUP CONTROLFILE in this case control file type is *"BACKUP"* but not *"CURRENT"* due to even you have all archivelogs and online logs you have to open database RESETLOGS statement.Actually after applying all archive and online redo logs ALTER DATABASE OPEN RESETLOGS internally sync and "Say" to control files "RECOVER FINISHED".Because CF type is BACKUP.
q2) You need to OPEN RESETLOGS. You can choose to create controlfile OR not create controlfile (i.e. open with the backup controlfile that was used for the RECOVER).
If you do a CREATE CONTROLFILE it has to be CREATE CONTROLFILE RESETLOGS, followed by ALTER DATABASE OPEN RESETLOGS.
in what circumstances, would i need to re-create the controlfile when i can still use the backup controlfile ? as in any case, i would still need to resetlog.
Rgds,
NoobIf you have backup controlfile then do not need recreate control files.And you need use backup control file.If you lost all backup of control files and copies then or you want change database name then you can use RECREATE CONTROL FILE again.

Is the macbook pro much better than any other laptop?

I am currently wanting to buy a laptop, I am deciding whether to buy a macbook pro or just a regular laptop. Is it really worth it to spend so much more?
Thank you! ~ mtumbler

Don't forget where you're asking that question.
Since nearly all people here have Macs, we obviously felt they were worth the price. "Much better than any other laptop" is a fairly subjective statement. All the major manufacturers have excellent high-end options. When comparing prices, you need to compare similar specifications and quality. You can certainly get cheaper PC computers, but similarly spec'd machines with similar build quality are generally around the same price (and actually sometimes somewhat higher).
The areas that most of us would agree puts Apple at the top are OS X, quality/design, and customer service. Only Macs can run OS X. For those of us that use OS X, we typically prefer it over Windows (by quite a bit). However, this isn't always a positive for someone moving over from Windows. There is a little bit of a learning curve. If you are going to need to be able to do everything you want, you need to understand that it might take a little time to figure everything out. You can install Windows alongside the Mac OS to help make the transition a little easier, but that requires that you purchase a copy of Windows. So far as quality and design... Apple has always been a leader in this area. However, as I had mentioned earlier, most major manufacturers have caught up in this area... at least with respect to their high-end offerings. It's really a matter of preference in terms of which you like more. No one offers the same level of customer service that you'll get from Apple. No other manufacturer has retail stores like Apple where you can go in with your machine and have someone (who knows about Apple products) check out your machine on the spot. Their phone support is also excellent and their user support community (where you're at now) is second to none.
So... most of us would agree that we feel Apple products are "better". But if you were to go to a typica PC forum and ask the same question, you'll find people who would argue fanatically that they're not. The reality is that there isn't that much of a difference in the hardware. You need to decide if something like the OS (which you probably don't have much experience using), design, and support are important to you.

The spinning beach ball of death (SBBOD) can be caused by many things. Common causes are not enough RAM, insufficient HD space or another process using a lot of the CPU's power. You can open Activity Monitor (Applications - Utilities - Activity Monitor) for many things including the %CPU column to see if there is an app using a large %CPU. Also click the System Memory tab and see how much FREE RAM it shows. As a general rule your system should have 500MB or more available.
Finally I'd recommend reading and using the Spinning Beach Ball of Death article for additonal troubleshooting steps.

Why does the elements 13 change resolution when going into the editor -- it is huge and unusable

why does the elements 13 change resolution when going into the editor? -- it is huge and unusable

Many mysteries...
Which is your OS version ?
Your screen is 1920 by 1080 pixels.
The problem appeared after having worked normally.
When we select a picture from the organizer (album) and click on the edit button. The editor software changes the entire computer resolution from 1920 x 1080 to 640 x 480 (very unusable).
That's not clear for me: did you click on the 'Edit' button on the bottom right part of the organizer, or did you use the menu or the right click popup menu to open the editor? In the second case, you are in the editor workspace.
We tried right clicking on the Elements 13 icon, select properties and under compatibility we made sure that "run in 640 x 480 screen resolution" was de-selected, and it was. Cannot find any properties window for the editor?
The editor has its properties in the 'Edit/preferences' menu, but there is nothing about resolution there.
Just to be sure : when you are in the organizer with the left 'Folders' panel shown, you highlight one of those pictures to edit. Then you right click and choose to "go to folder". Do the images are shown as 'offline' ? If that is the case, the original are on an external drive which is not connected, and what you are seeing is a 'preview' copy on your computer with 640 x 480 resolution.

Creating a real instrument track is a very silent matter normally. Once you start recording, you can indeed pick up noise - but that depends on what you're recording, how you're recording etc. - you didn't tell us anything about it.

Why does the Yosemite Finder become unresponsive when moving a file within my USB Flash stick?

Why does the Yosemite Finder become unresponsive when moving a file within my USB Flash stick? I have to Relaunch the Finder to get it working again.
Background / other symptoms:
The Flash drive in question has been formatted HFS.
I get no error messages, including on the Console, and no sound indicators.
I can copy files, using the Finder, from a hard-drive to the usb flash drive with no problem.
Finder copying on this stick works just fine on my other Mac.
I can move files within another (FAT32-formatted) USB flash drive.
The quirky USB HFS Flash drive works fine on my other Mac.
Outside of the Finder, I can use mv just fine to move the files on the HFS flash drive.
If the HFS-formatted Flash drive were faulty, I would at least expect some sort of error in the Console app, but perhaps not from the Finder.

Why does the Date Created metadata change when images are exported?How do I stop it from changing?

why does the Date Created metadata change when images are exported? How do I stop it from changing? I must have a prefernce set up wrong.

I don't know what OS you are using, or what application you are using to view the data about your exported files, but on Windows and using Windows Explorer the "Date Created" field relates only to the date that the exported file was created, i.e. if viewed immediately after export it will show the date created as being the same date. In order to view "Capture Date" in something like Explorer, you first have to ensure you have included the Metadata as Conrad outlined above, then you have to adjust the display properties of Explorer to show the "Date Taken" field. Here is an example, part of a folder I exported back on March 3rd, note the difference between that last two dates:
