What is the underlying issue? Here are the symptoms...
I have a combination of issues here, and they all seemed to be linked but I cannot wrap my head around it. Here goes:
(1) System Preferences freezes when I try to alter trackpad settings
(2) Mac Software Updates will not install and cites an "input/output error"
(3) Google Voice & Video Plug-In will download but doesn't link properly to Gmail, and I continue to be prompted ot download plug-in
(4) Skype downloads without a problem, but freezes upon first launch
I have rebooted many times, deleted downloads and repeated them dozens of times, and tinkered with a few smaller elements. But what is my underlying issue here? Any thoughts?
Thanks!
Nate

You installed a variant of the "VSearch" trojan. Remove it as follows.
This malware has many variants. Anyone else finding this comment should not expect it to be applicable.
Back up all data before proceeding.
Triple-click anywhere in the line below on this page to select it:
/Library/LaunchAgents/com.laser.agent.plist
Right-click or control-click the line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
Repeat with each of these lines:
/Library/LaunchDaemons/com.laser.daemon.plist
/Library/LaunchDaemons/com.laser.helper.plist
Restart the computer and empty the Trash. Then delete the following items in the same way:
/Library/Application Support/laser
/System/Library/Frameworks/v.framework
The trouble may have started when you downloaded and ran an application called "MPlayerX." That's the name of a legitimate free movie player, but the name is also used fraudulently to distribute VSearch. If there is an item with that name in the Applications folder, delete it, and if you wish, replace it with the genuine article from mplayerx.org.
This trojan is often found on illegal websites that traffic in pirated content such as movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Then, still in System Preferences, open the App Store or Software Update pane and check the box marked
Install system data files and security updates (OS X 10.10 or later)
or
Download updates automatically (OS X 10.9 or earlier)
if it's not already checked.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

"ZipCloud" is some sort of cloud-storage service with a doubtful reputation. The OS X client is sometimes distributed along with malware. Although ZipCloud may not be malicious itself, it should be deemed suspect by virtue of the company it keeps.
To remove ZipCloud, start by backing up all data (not with ZipCloud itself, of course.)
Quit the application, if it's running, and drag it from the Applications folder to the Trash.
Triple-click anywhere in the line below on this page to select it:
~/Library/LaunchAgents/com.jdibackup.ZipCloud.autostart.plist
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with a file selected. Move the selected file to the Trash.
In the same folder, there may also be a file named
com.jdibackup.ZipCloud.notify.plist
Move that to the Trash as well.
Log out or restart the computer and empty the Trash.
C
The following Safari extensions are malicious and should be removed in the Extensions pane of the Safari preferences window:
Searchme
Do the equivalent in the Chrome and Firefox browsers, if you use those. Never install any extension with the words "Spigot," "Conduit," "Genieo," or "Trovi" in the description.
D
Some of your user files (not system files) have incorrect permissions or are locked. This procedure will unlock those files and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
Back up all data before proceeding.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):
sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
Start up in Recovery mode. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
resetp
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
▹ Restart
from the menu bar. -
My system.log shows numerous errors such as: "kernel[0]: ... dyld_shared_cache_x86_64': owned by uid=89 instead of 0" ...
What is the underlying problem here?Are you trying to install anything by any chance??
update_dyld_shared_cache ensures that dyld's shared cache is up-to-date. This tool is normally only run by Apple's Installer and Software Update, as they are the only official ways for OS dylibs to be updated. But if for some reason you used another mechanism to alter an OS dylib, you should manually run update_dyld_shared_cache. -
This is to sum up the problem. Here are facts :
This is to sum up the problem. Here are facts :
1. Java process size grows to ~ 3G and eventually exhaust native memory. Only
data segment of the process grows in size.
2. Java heap size remains stable, way under the max size. Perm generation
size is stable, way under the max size.

Exception in thread "CompilerThread1" java.lang.OutOfMemoryError: requested 612052 bytes for Chunk::new. Out of swap space?100M doesn't seem too extreme ... I ran a test program that created 100 sleeping threads, and ps -l reported the process size as 77M. I don't know Linux well enough to know the threading model (I suspect it's LWP-per-thread, which means that ps -m will give correct output).
However, given what you've shown (heap doesn't grow, process map does, failure occurs in code that starts a new thread), it really seems that your problem has something to do with too many threads.
My first thought, since I've seen it before is that there may be fragmentation of the memory map, such that there's no available segment when the JVM tries to allocate the stack for a new thread. When I saw this problem, the JVM (1.3 Solaris) was using a pretty naive approach to mapping those blocks, such that a few long-lived threads would cause it to run out of space. This information is available in the /proc/maps directory (man proc for more info).
There could also be some limit to the number of threads you can create. I know that Solaris returns ENOMEM when it's unable to create a thread; not sure what Linux returns.
Finally, I'm going to suggest again that you put logging messages in the thread factory that you're giving to the pool. Since you control that code, it's an excellent way to watch what's really happening at the time you run out of memory. -

Please Please Help with Projectile Project Here are the Codes
I've got three(3) classes a Model, a view, and a controller.
This is a project about projectiles.it is an animation of a cannonball being fired from a cannon and travelling under the effect of gravity.A cannon fired at angle 'a' to the horizontal and with an initial speed 's', will have an initial velocity given by:
vx := s * cos(a);//velocity x equals the speed multiply by the cosine of angle a.
vy := s * sin(a);//velocity y equals the speed multiply by the sine of angle a.
Here are the code.

if the cannon ball land in the bucket it should stop and the animation should indicate a 'hit' in some way. maybe by displaying a message.
if the cannonball hits the outside of the bucket it should bounce off.
Extra Notes.
1) The acceleration due to gravity is 9.8m/s to the (power of (2) eg s2.
2) The distance travelled in time t by a body with initial velocity v under constant acceleration a is:
v * t + a * t.pow(2) div 2;
The velocity at the end of time t will be v + a * t.
Distance is measure in pixels rather than meter so for simplicity we use 1 pixel per meter

Please Help with Physics Project Here are the codings
I've got three(3) classes a Model, a view, and a controller.
This is a project about projectiles.it is an animation of a cannonball being fired from a cannon and travelling under the effect of gravity.A cannon fired at angle 'a' to the horizontal and with an initial speed 's', will have an initial velocity given by:
vx := s * cos(a);//velocity x equals the speed multiply by the cosine of angle a.
vy := s * sin(a);//velocity y equals the speed multiply by the sine of angle a.
Here are the code.

When i pressed the fire button nothings happens. I'm going crazy. Please please help!Hi,
U put something on forum and keeping silence.If it is not necessary dont put in forum.I moved your cannon ball.If u want continous movement I need some more information.

If I scroll to bottom of screen in *App Store/Featured, I can see that the Apple ID is my new email.
Upon “updating” Apple ID reflects OLD email.
Deleted accounts, re-added accounts.
Signed out and signed in with new UN/Email
Issue remains the same.To migrate your data to a new iCloud account go to Settings>iCloud and turn off all synced data (contacts, calendars, etc.), when prompted choose to keep the data on your phone. After everything is set to off, scroll to the bottom and tap Delete Account. Next, create the new iCloud account on your phone and turn on syncing for contacts, calendars, etc again. If prompted, choose Merge. This will upload your data to the new iCloud account.

That way you still have the benefit from hardware acceleration, but may not suffer from rendering issues.
You can also try to uninstall Windows update KB2670838 if you have this update.

I have attempted to sync my new iPod touch 4th gen. with my current PC running Windows XP and everytime I attempt it I get the dreaded blue screen, here are the error codes- 0x0000007E; 0XC00000005; 0X00000000; 0XBA51B7C8; 0XBA51B4C4 any suggestions?
In the course of your troubleshooting to date, have you worked through the following document?
iPhone, iPad, or iPod touch: Windows displays a blue screen message or restarts when connecting your device -
The song “If We Are the Body” could not be used because the original file could not be found. Would you like to locate it? This notice keeps coming up even though I have iTunes Match. What do I do?
This usually means the original music file has been been deleted from the HDD. If you feel it has not then click "locate" and navigate to where the song file is on the HDD and choose it. You can use Spotlight to locate it if necessary.

What is stored under "other" category on the iPad?
The long and short of it is that you will probably have to restore your iPad. That giant "other" space is a sign of a corrupt file from a sync, I am pretty sure, but I am quite sure that the way to resolve it is to restore the iPad.
You can search the discussion site for similar threads but I think you will find that a restore is the way to correct it. Read this one.

The only thing showing are the titles, but the full audio track is playing. What did I do? How do I fix it?
Apple TV 1st generation or 2nd?
I would try plugging in the HDMI from the ATV to a different HDMI port on your TV and even trying the ATV on a different TV altogether...sounds like the HDMI port on your TV might be bad or a bad connection. Keep in mind you'll need to switch the TV input to the new HDMI port -
I dropped my iphone 4 into the water and then i tried the rice method. The rice solved the water issue but now the screen won't work. what should i do?
I guess your definition of "solved" is different from most...
Make an appointment at the genius bar of your local Apple Store and get an out of warranty replacement. -

does anyone have any other ideas to try or observations on compatibility between iPhone, Samsung, and HTC for international SMS?
International texting can be a crap shoot. It's not a question of phone compatibility but of carrier interoperability. I regularly text from my iPhone to my (domestic) colleagues (who all have Samsungs) and to a friend with and HTC (an old one, too) without difficulty.
One last question - I've never deleted my SMS from my friend, and would prefer not to. But it's pretty much the only thing I haven't tried. Does anyone think this might solve the problem eg if there are orphan texts somewhere on the network?
I'm not sure there really is such thing as an orphan text. If a text isn't deliverable, the carrier deletes it from it's system. SMS is quite a robust system.
There is no general incompatibility between iPhones and other phones as far as texting is concerned. I suspect what you may be seeing is a combination of an old phone and/or an issue with one or both of your carriers. Intermittent technical problems are some of the most difficult to solve.
I have vague memories of people saying that a trailing space at the end of the text made a difference when they had similar problems. It was a couple of years ago. (Honestly, this problem doesn't come up that often!). I don't recall if putting in the traling space helped, or removing it helped. It may also just have been magical thinkning.
Best of luck.
