What is ANT HAL Service and why does it have such insanely many permissions?

What the subject says. What does it do? Why is it there?

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 ...

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?

Why does Java have such a large footprint?

I've been curious about this topic for a while, but I haven't ever looked into this to any depth. I also posted this to stackoverflow but haven't gotten any solid responses so far:
http://stackoverflow.com/questions/1107991/why-does-java-have-such-a-large-footprint
Java - or at least Sun's Hotspot JVM - has long had a reputation for having a very large memory footprint. What exactly is it about the JVM that gives it this reputation? I'd be interested in a detailed breakdown: how much memory goes to the runtime? (The JIT? The GC/memory management? The classloader?) Anything related to "auxiliary" APIs like JNI/JVMTI? The standard libraries? (Which parts get how much?) Any other major components?
I realize that this may not be straightforward to answer without a concrete application plus VM configuration, so just to narrow things down at least somewhat: I'm primarily interested in default/typical VM configurations, and in a baseline console "Hello world" app as well as any real-world desktop or server app. (I'm suspecting that a substantial part of the JVM's footprint is largely independent of the app itself, and it is in this part that I'd like to zoom in, ideally.)
I have a couple of other closely related questions:
Other similar technology, such as .NET/mono, don't exhibit nearly the same footprint. Why is this the case?
I've read somewhere on the intarwebs that a large portion of the footprint is due simply to the size of the standard libraries. If this is the case, then why is so much of the standard libraries being loaded up front?
Are there any efforts (JSRs, whatever) to tame the memory footprint? The closest thing I've come across is a project to reduce the on-disk footprint of the JVM [1] and to modularize the standard library [2].
I'm sure that the footprint has varied over the past decade or so with every new version of Java. Are there any specific numbers/charts chronicling precisely how the JVM's footprint has changed?

Presumably versus some other VM. I would suppose the fact that much of the VM is written in java has something to do with it.

Not sure I agree with that. What size do you see with a .Net app that uses 3.0/3.5?
I've read somewhere on the intarwebs that a large portion of the footprint is due simply to the size of the standard libraries. If this is the case, then why is so much of the standard libraries being loaded up front?
Good question. There is a feature that allows multiple VMs to use the same memory footprint version of the loaded libraries. That is a new feature and it isn't clear to me if it covers the entire API. I do not know if that is dynamically built.

What is a PRAM reset and why did I have to do it ?

My very new (4 days) 20" Aluminium iMac was getting quite noisy, so much so that I called for support today.
The Apple tech explained how to do a 'P.RAM' reset, which in fairness does seem to have resolved the issue. (something to do with a FAN, I think).
I would like to know more about the causes of this, and why would I have to do it a such a new machine ?
Is there something wrong with my machine ? What are the chances I wil have to do this again ?
Thanks....

All, thank you for your time and valuable information. I am relieved that nothing is wrong with my system, but I must say that I find it is a little odd that a user has to do take these steps after making hardware or software changes to the system. I would expect this to be done as part of the install routines. Perhaps that is why other (you know who) systems need rebooting after most hardware or software changes.
I know Apple like to be seen as the machines where such things are not required, but clearly they are !
Thanks again.

Photoshop CC banding issue, what is the fix? And why does Adobe not address this?

I am having a issue with banding. I paint in my backgrounds but instead of a nice smooth graduation I get banding. This occurs in 8 bit and 16bit. I have changed the drawing mode to basic. I have even photographed a graduated background and it still has banding. Here is my computer info. Thanks.

There have been several others who have tried to illustrate a problem like what you describe, and it's been traditionally very difficult to distinguish between what we expect to see and something that's abnormal. There is not just a single identified problem that fits your description.
The best you can do is be very, very thorough in your descriptions, including exactly what you're doing in order to create an image where you see the problem. Include as many screen grabs as you can, concentrating on showing what you consider a good result vs. bad.
Good luck.

What is DNS Services and why does it use so much data?

I have 300MB to use a month on my iPhone 4S (most recent iOS) and I'm normally pretty good with it because I'm connected to WiFi a lot. All of a sudden, my data usage spikes and my DNS services usage has gone up to 40MB. What is this and how do I keep it from spiking like this? It's incredibly annoying.
Also, any other tips on saving data while connected with the 3G? As mentioned before, I only have 300MB so I like to stretch it for the month.

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 a Profile Mismatch and why does it always show up?

b Question
Every time I open a file I get a prompt which reads: Embedded Profile Mismatch.
Embedded: Camera RGB Profile
Working: Adobe RGB (1998)
I always choose the default, which is the "embedded profile (instead of working space).
I have no idea what any of this means. I know that it started doing this after I chose something recommended in a Photoshop book.
Can someone please show me how to get rid of this prompt and point me in the direction of information that will help me choose the best profile?
b Answer supplied by Richard Rose
First the good news - your work flow is Color Managed.
Now the bad news - You have no idea what that means, nor how you are achieving that desirable situation.
You really need to start at the beginning and learn what color management is all about. For some reason lots of people get very confused and mislead trying to wrap their brains around the subject. It's really quite simple.
There are many named "color spaces" in which to work in Photoshop. you have chosen Adobe RGB (1998). You chose that color space in Photoshop CS under "Color Settings."
That's a good "general purpose" color space to use. It's very useful for workers preparing images intended for color reproduction in print (on a printing press). But it'll do for almost any use you have for your images. If your images are destined mostly for the Web, working in sRGB might be good. (I recommend just staying in Adobe RGB 1998)
The "short answer" as to why Photoshop needs to work in some particular "color space" is that the program must "translate" colors from their source (a digital camera, a scanner, a a graphics program) into a destination (display on a computer monitor screen, a particular printer, output for printing press reproduction, etc).
There are many compromises that take place in that translation process, and the requirements for all the possible conditions that must be satisfied (hue, saturation, how light or dark the image appears) cannot always be met. Something has to give somewhere.
Named color spaces (Adobe RGB, sRGB, Color Match RGB, Ekta Space, etc) make a number of assumptions and decisions about how color translations (conversions) should be carried out before Photoshop ever gets its hands on the image, and makes it much easier for Photoshop to carry out the conversions and maintain accuracy in converting (for instance) from a digital camera's idea of an image to the needs of your computer monitor (so you can see an accurate resemblance of the image) to the needs of a printing press, so that the image looks correct in a magazine.
The conversion process is carried out with the aid of "profiles." A profile is a set of data that is embedded in an image file that describes to any program that wants to read it, what the image data means in terms of color.
Without the profile, your digital camera's RGB file simply contains arbitrary RGB values. Yes, a particular pixel with high R values will be reddish, and another pixel with high B values will be blue, but the actual red or blue of those pixels as they relate to the original scene is unknown. The camera profile embedded in your file lets Photoshop know, to a high level of accuracy, just what hue of red, and just how much saturation is present, and how light or dark the red was in the scene. The profile's coding of this information is based on a color measurement system called CIE which uses several different mathematical models to carry out some VERY complicated computations. There are CIE Lab models, CIE XYZ, and others. These models are as close to an "absolute" color reference system as we have.
Thank God you are using camera files that actually have profiles! When you open such a file, Photoshop is "warning" you that the image information is in a color space other than the default Adobe RGB space. You told Photoshop to warn you about such "mismatch" when you set Color Management Policies in the Color Settings section.
Photoshop is telling you that "something" needs to be done. It can honor the camera's color space, from it's own frame of reference (Adobe RGB 1998) and work on the image, accurately handling the color information for screen display and eventual output. That's what you tell it to do when you "accept" the embedded profile. That's not bad, everything will work correctly, because Photoshop will have made internal conversions that remain active as long as the file is open, but there is something you have to keep in mind - when you save the file, Photoshop will save the original camera profile with it. Then if you open the file again, the same "warning" will occur.
That camera profile is as valid and useful as any other profile, but because it is not a commonly recognized color space may cause a problem in some other workflow. (Notice I said MAY. ICC color profiles SHOULD be ok in any program)
It is probably better to choose "Convert to working profile" on opening the file. From that point on, nothing will appear different to you, because nothing has really changed. Photoshop will handle the file as it did before, internally converting the color information as necessary with regard to its working space. But when you save the file, the Adobe RGB 1998 profile will be embedded in it. If you re-open it, you will get no mismatch warning, and the file will be recognized by most other image handling programs as having a "standard" color space.

Thanks! I still don't understand the concept of "saving power" in this context. Does that relate to a laptop running on battery, and some popups consume more battery power? Or does this refer to CPU capacity? I have never had any issue that I know of in these areas. I would understand the warning if it cautioned me about insufficient bandwidth, but that doesn't seem to apply here. In any case, am glad to find that this is a feature and not a bug.

I get notifications of changes for radiowmpcoregecko7.dll. It is indicated that it is from Firefox. What is this file for and why does it keep changing.

About once a week to two weeks I receive notification through my anti-virus that this file has been changed. It appears to be part of Firefox. What is it and what does it do?
Thank you.

What is Safari Power Saver and why does it keep popping up?

On many sites I get a popup asking me to activate or install Safari Power Saver. I sometimes close the popup, more often just leave the site. Is there any danger to clicking ok? Is there any reason to do this? Is there any way to avoid this without turning off popups everywhere?
Thanks!

What is a restore report and why do I have two of them in two days time?

When I try to open these reports all I have on the screen is yb in the upper left hand corner of the screen. The first has a date of 11-26-10 at 10:41:33 AM and the second is 11-27-10 at 4:44PM. These are showing up as icons on my desktop. If anyone can explain, please do so in simple terms, am not very computer literate.

cor-el, your interpretation appears to be correct, but as I said I am not computer literate. I went to wikipedia but the explanation may as well have been in Greek for all that I understood. And now half of my desktop shortcuts have disappeared. I am baffled here and really don't know what to do. Am concerned as to whether I have a serious problem or not.

What is the "protected_media" folder and why can't I access it?

I was going through File Manager and saw a folder called "protected_media". Trying to open it gives me a "Folder Unavailable: You don't have permission to access this folder" message. Why do I have this folder and why can't I access it?
Also, what is the "misc" folder? Why does it have a folder inside it called "android"? Why can I go Device/misc/android/DCIM/Camera and find copies of everything that is in the Device/camera folder? Can I delete "misc" without messing anything-up?

the misc folder is for android apps and are virtual links to the files.
Do not delete the files in there or they will be gone from both places.

What is better to use and why?

Hi,
What is better to use and why?
We have written follwing statements to check the existence of interested record in table.
1).
select count(*) from emp where deptno = 20;
2).
select 'X'
from dual
where exists (
select 'X' from emp
where deptno = 20);
Thanks and Regards,
Rushang Kansara

Assuming a large table, number two would be the fastest. If empno in unique, you can leave out the where exists part and just select x from emp where empno = 20. If empno is not unique, then using where exists can be faster. Assuming that empno is not unique, query 1 may elect to scan the whole table looking for that empno. Number 2 can use the index and return your result in, typically, three LIOs.
Again, it all depends on your indexing, size of tables, and uniqueness of key upon which you are searching.

Android.process.acore? What is this and why does it keep not working?

Help: I've had my Lucid 3 phone since May and this phone has been the most confusing thing to operate. I'm currently having three (3) issues:
The Wi-Fi is not working...I keep getting the symbol refreshing. I can't turn the Wi-Fi on or off. I read "Turning Wi-Fi on..." when I go to the setting for Wi-Fi but this has been going on for 3 hours. C'mon! My Wi-Fi at home is working great; that's how I'm writing this post. Help!
To add to the misery: I keep getting a pop-up notification that reads: "Unfortunately, the android.process.acore has stopped." What is this and why does it not work. The phone's been getting this message for a week now...help!
Last concern: I'm still not getting multimedia texts (particularly pictures). The data and Wi-Fi were on...well, that's when the Wi-Fi was working (please refer to complaint #1 above). What the heck?
This phone is terrible news and I can't wait to replace it. In the meantime, the phone needs to work. Help.
-Salo

We certainly want to clear up all the confusion and have a working phone in your hands, srodezno. Let's take this one issue at a time:
1. How long ago did this trouble with WiFi start? Are you able to connect to any alternate WiFi signals other than the one at home?
2. Do you get that notification when you access anything in particular? Did it begin when you updated or installed any application?
3. Are you still able to access other data services (web, apps, Play Store, etc) while the WiFi is off/not working? Are you able to send the MMS messages?

What are mapping services and why they use so much cellular data?

I previously had an iphone 5 and my monthly cellular data consumption was about 250MB.
I recently switched to an iphone 5S and the cellular data usage is about 250MB per week!
I try to monitor and reduce the usage but the mapping services in system services is always very high!
What is this? Can I reduce it?

Mapping Services ( story ) :
In April 2011, iPhone and iPad users were surprised to discover that, not only was their device keeping track of where they’d been, it also was storing very detailed location information in a plain-text file on the phone. The data was derived by the cell towers and Wi-Fi hotspots the devices encountered, and was added anonymously to a crowdsourced database.
Apple later said the devices were keeping more information than intended due to a bug, and issued a patch that reduced the amount of data. But, because it was used to improve and speed up location services, the practice continued.
And now, in iOS 7, Apple has added a tool that lets you see what your iPhone knows about where you go.
If you’ve got an iPhone 4S or later running iOS 7, follow these steps:
1. Go to Settings, then Privacy > Location Services.
2. Scroll to the bottom of the list of apps that use Location Services (and feel free to marvel at how many apps do!). Tap System Services.
3. Tap on Frequent Locations, then scroll down and look at History. You’ll see at least one city there, more if you travel.
4. Tap a city. You’ll see a list of locations you’ve visited in the city.
5. Tap a location. You’ll see a list of the dates and times you visited that location.
Why in the world would Apple collect this kind of detail about your movements? It does so to enable features like Next Destination, found in the Notification Center, which is the screen you see when you swipe down from the top of the iOS display. Next Destination looks at your travel patterns and offers information about how long it will take to get to the next place you typically visit during the day.
If having all this location data collected by your iPhone makes you nervous, you can turn it off at Settings > Privacy > Location Services > System Services > Frequent Locations. Note that it is turned on by default, so if you don’t want your phone logging your whereabouts, you’ll need to turn it off.
The Next Destination feature is similar to one found in Google Now, which uses location and your habits to offer up useful information without your asking for it. Google Now is found in the Google Search app on both Android and iOS. On Android, you can add a Google Now widget to your home screen to make the feature more accessible.
In fact, Google collects similar information about you – and in greater detail - if you use its location-based products. Google stores your location data on the Internet, and you can see it on any Web browser.
Make sure you’re logged into your Google account – say, through Gmail – and then go to google.com/locationhistory. You’ll see a map showing location visits for today, but click the Dashboard link at the top of the page and you’ll see this:
To turn this off, click the gear icon in the upper right corner of the Location History page and choose History Settings. Then, click Disable and Save. There’s also a History Management link that lets you delete history items that have already been collected.
Location services are really an integral part of a ton of iOS apps, using the internal GPS system to add Instagram photos to a map, checkin with FourSquare or Facebook, or let your friends know where you are with one of many “on my way” apps, like Glympse or Twist.
If you’re battery is dying, however, the location services are the first thing you should turn off, as they suck up a lot of your iPhone, iPad, or iPod touch’s power needs, what with their background data sending and receiving and such.
Here’s how to turn them off.
Tap your Settings app to launch it, and then tap on Privacy. You’ll be able to turn the toggles OFF for any specific app that has privileges to access your GPS location by scrolling through the list and tapping them all. I do this on a fairly regular basis for both privacy and battery savings. I figure that with less apps accessing my location, the less battery power in total is being used for that function.
If you want to turn off Location Services completely, then simply tap the main toggle at the top to OFF, and you’ll stop using them. This will keep your apps that need it, like Maps or Compass, from knowing where you are, but the battery will thank you.
Follow the above steps to turn off Location Services :
