What is XUL runner AND why does it state couldn't run XRE functions

When I tried to update either 6.2 or now 7.0 on my xp laptop I get the XUL runner popup and it states the above about XRE function. Since I don't know what either means. How can I do a sucessful update.

What is application memory and why does my macbook pro keep running out of it?

what is application memory and why does my macbook pro keep running out of it?

There is excessive swapping of data between physical memory (that is, the memory chips on the logic board) and virtual memory (one or more files on the startup volume.) That activity is relatively slow and causes the whole system to be less responsive. It can happen for two reasons:
          A long-running process with a memory leak (a kind of bug)
          Not enough memory for your usage pattern
Please note that if the cause is a memory leak, installing more memory will not help. That's likely if you already have more than 4 GB of memory. Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
These instructions are for OS X 10.9 and later. Some details may be slightly different for earlier versions of OS X.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the View menu, if it's not already selected. Select the Memory tab. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
          View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The processes named "Safari Web Content" render web pages for Safari. They use a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider them prime suspects.
Another process often implicated in memory leaks is "inkjet4" or "inkjet8," which is a component of the HP printing software. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. Empty the print queues in the Printers & Scanners preference pane (which has a slightly different name in each recent version of OS X.) If you don't use an HP printer, reset the printing system. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
"Wired" memory should be a small part of the total. That memory is not swapped, but it makes less physical memory available which may then result in swapping. If you have a lot of wired memory, that's usually an indication of a memory leak in a third-party program that modifies the operating system at a low level. Ask for guidance in that case.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.

AVG reports these sqlite cookies each time firefox starts. they usually belong to tribalfusion or some other tracker. How do I block them in the first place. I thought firefox is a safe browser. Did not have this problem until I upgraded to 3.6.

Check your Applications folder. If you don't want the app, just drag it to the Trash.

What is "Directory Service" and why does it "use up 194%" ?

What is "Directory Service" and why does it "use up 194%" on my istat CPU app monitor?
Ever since I installed Leopard I've noticed this happening more and more - especially when I install an external hard drive or unplug my ethernet line - this is plainly weird and never happened under Tiger - the temperature shoots up to 84° also - I always to a restart to get rid of it but it's kind of worrying....anybody have any ideas?

Had this happen myself.
It does have something to do with Spotlight/searching. Should go away after a while, or so I have heard from other users, 'cause it hasn't stopped driving me and my fan mad yet.
Am going to have my MacBook index and follow-up on indexing and whatever else it feels is necessary to finally allow me to search in peace over the weekend while locking it away where I can't hear it.
Hopefully that does the trick.
If it wasn't for things working better/faster and most things looking better I might actually consider taking Leopard off again ...

".alias" file in LV 8.2 DSC - What is in there and why does it change?

Why does the alias file get updated every time I open and close the associated project WITHOUT SAVING ANYTHING ?
Repeat:
I did not save anything.
What is being saved if I did not change anything?

Hi all,
I can give you some reasoning behind the 'why.' The aliases file
lets the project know the location (IP) of each of the targets in the
project to facilitate communication between them. This is very
useful in Real-Time and FPGA applications containing multiple
independent targets. If you create a new RT cRIO Controller in
your project, for example, you'd find your aliases file now looks like
this:
[My Computer]
My Computer = "10.0.31.147"
[RT CompactRIO Target]
RT CompactRIO Target = "10.0.35.254"
The reason why the aliases file is updated just by opening the project
(even without saving the project) is that the project file may have
been moved to a different computer, or your IP address may have changed
since the last time it was opened. LabVIEW needs the current
address of each of the targets to be able to, among other things, send
and receive FTP files, set up front-panel communication with the
target, and properly configure shared variables. This behavior
should be present in all flavors of LabVIEW 8.2, and not just with the
DSC Module.

What is 'Backing up' and why does it take so long even if my library is identical to my ipod?

I've just plugged by ipod touch into the computer to sync it and it keeps telling me the ipod contains stuff that isnt in my library (eventhough my library is identical to the content on the ipod) and that if i dont back up i will lose this stuff, i clicked back up and now it has been backing up for over 2 hours! what is it doing and why is it taking so long?

TC has to check to see which files need to be backed up. So its going thru the file directory and looking for any changes since the last backup. Do you have a lot of files on your Mac to check? Or are they just a small number but very large. If its the former, then that might be the culprit.

What is kernel_task? And why does it use so much memory?

I have an iMac 27 inch late 2009 purchased new in July 2010. It has a 3.08 Ghz Intel Core 2 Duo Processor and 4 GB of Memory. I recently upgraded to Yosemite and just now was unable to save an Excel document to an external hard drive with plenty of space with the warning I did not have enough memory. I went to my activity monitor and indeed there is very little memory and at the top of the usages of memory is kernel_task? I don't know what that is and why it requires so much system memory.
Also, there is an installation I aborted for an app I realized I didnt need and for some reason something it out there still taking system memory and I get a message when I shut down that it can't install. How do I delete that.

DNS (Domain Name Service) is the Internet "address book" of web sites. Whenever you go to a site such as http://apple.com your browser must make calls to the DNS server specified in your Network Settings to translate "apple.com" into Apple's IP (Internet Protocol) address of 17.178.96.59. Any time you access any Internet resource (such as sending or receiving email, playing multi-player games, using a browser, Using any app that accesses data on the Internet such as news, weather, stocks, etc) one or more DNS lookups must be made. Many web sites have content from several different sites. Each site referenced on the page must also be looked up. Each query is small (~100 bytes), but they can add up.

What is .rar? and why does it spawn a .exe file on my computer?

I download things often, and have recently gone through some old discs that were burned by a pc, and downloaded them onto my new macbook pro.
Just curious what this 34544.rar thing is and why it expands, but doesnt' open.
In laymens terms, could someone fill me in?
It looks complicated. When I clicked on it, it made 2 new files there in my folder. dddd.1.exe, followed by ddd.exe-
Id like to know what that is.
Thanks for your time as well.

A .rar file is a form of archive developed by Eugene Roshal, and called Roshal ARchive format (RAR.)
The contents of the archive you have is obviously a .exe file which is a DOS or Windows executable binary (hence, exe.) They do not run on Macs.

Leave the phone connected to iTunes and let it boot the phone up again. iTunes should then try and update the firmware again once it detects the phone.

The type of file the name is associated with is in use for web browsers, and some content online, in both Mac and PC.
But your computer should not need it installed, so refuse it and check your browser security and privacy settings...
You should look into the security settings for web pages, and choose to not allow cookies from other pages, or images from other sites, and see what kinds of things you can screen or filter, that way. And privacy, you can be more anonymous when visiting pages and still see their content.
re: ASPX pages are also called ".NET Web forms." They can be identified in a Web browser when the URL in the address field ends in ".aspx". Or in a hidden or download file. There are warnings, found in searching the ASPX topic, and as executable files, you should not bother opening them... *example:
Warning: Take great care when opening executable file formats received via email or downloaded from websites you're not familiar with.

What is Solver? And why does it quit on launch?

When I click on Launch Pad, one of the icons that comes up is "Solver". I've tried launching it, but all it does is open Excel and then quit. It offers me a box to submit a report to Apple and relaunch. It quits every time.
What is it and what is it supposed to do? Anyone know?
Thanks in advance!

What is "date created" and why does it change?

I have Photoshop Elements 10 that I am using with Windows XP Service Pack 3, a Pentium 4 CPU with 3 GHz, 2 GB of RAM and 48.6 GB of free disk space.
None of the "dates created" in Properties match the date the picture was taken. What does "Date Created" represent? Is it the date that the images are pulled into a catalog in Organizer?
I have multiple catalogs that show creation dates that are later than the date modified, (example: date created of June 2012 and a date modified of March 2012). How is it possible that the date created is later than the date modified? Shouldn't the date created be earlier than the date modified?
Also, I have had several instances in which the date created was changed again, making the system think it was a "new" image in my watched folders. Shouldn't the Date Created remain constant? How can I keep the date created from being changed?

What is nipalk.sys and why does it give me the Blue Screen of Death?

Recently I purchased a 6211 USB data acquistion unit. Everything worked fine until one day Windows Explorer crashed (we all know how rare that kind of event is...). When I re-booted, I got the Blue Screen of Death, with a message about nipalk.sys being the culprit. I booted in Safe Mode and re-named this file, and then was able to boot normally and re-install the driver software for the 6211, and everything was fine...for about a week, when Windows Explorer did it again (Oops!).
Does anyone know:
    1. Which exact part of the install supplies nipalk.sys? It is a huge install with multiple parts accross 2 CDs. I could save a lot of time if I could restrict the install to just repairing the damage.
    2. Can I just make a copy of nipalk.sys and tuck it away in some corner of my hard drive to use as a replacement when this happens?
    3. I'm guessing that nipalk.sys is used by the little system tray icon that watches out for DAQ devices to be plugged into my USB. Is this guess correct? Can I turn this feature off for the 99% of the time I'm not using my laptop for data acquisition? Will that protect me against the gorking of nipalk.sys when Explorer goes down?
    4. What is this driver doing that its file disk becomes corrupted during a Windows Explorer crash?

Paul-
OK. When I can afford the time, I will try removing all NI software and re-installing. I have LabVIEW 8.0, DAQmx (of course), NI Vision development, and IMAQ.
I also had LabVIEW 7.1 on my machine because it was too much trouble to
remove it when I upgraded to 8.0 I have since removed 7.1, but I think there are still a lot of older versions of the "extras" that came along with it still lurking on my hard drive....
I was hoping for some guidance for a short-term "work around:"
1. If I just re-install DAQmx, can I make a copy of nipalk.sys and store it somewhere as a back-up to avoid the painfully long 2 CD re-install of DAQmx?
2. If the answer to 1 is "no", then exactly what part of DAQmx installs nipalk.sys? It is a multi-part install, and if I know which part is responsible for nipalk.sys, I can repair just that and save a lot of time.
To answer your questions about version: I'm not sure. I don't have convenient access to the disks at the moment, but they came with my 6211, which I ordered in May of 2007. I would be tempted to call it "the latest", but DAQmx seems to get updated quite frequently, so let's just call it a "recent" version.
Thanks,
-Geoff
