What causes Terminal beep delay?

Sometimes in the Terminal, when I hit backspace when nothing is typed, it takes a second before it beeps. I know this is a weird question, but what determines when it does? Is there any pattern?

Hi-
I think it's just a matter of the Mac needing to load the beep sound and set up the audio hardware to make it beep. I bet if start paying attention, you'll find that the delay is the first time it beeps after you start Terminal, or after it's been sitting without activity for a long time.

For products produced after 1999:
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)

What causes sometimes long delay in getting thumbnails.

See attached screen capture. This tends to happen, the farther back in time I look for old photos. Entire pages of thumbnails are missing. They only get retrieved when I page down, but sometimes never. Sometimes I have to click on the blank thumbnail in order to force it to appear. This makes it difficult to look for old photos. I just assumed it saved all this information:
Doing an f5 reftresh has no effect. My catalog (about 5gb) and previews (30gb) are on a dedicated Crucial 256gb sata-3 SSD which benches very fast, so the drive should not be the cause. Moreover, the fact that they often never appear should rule out the drive speed. I don't see a lot of settings to control this sort of thing. What might be causing this failure to display thumbnails?
Thanks!

An image must be on screen for its thumbnail to be created. Scrolling through your library in Grid view and waiting for the image thumbnails to generate on screen should fix it. It's been that way from the gitgo.
Thanks for the reply. Are you saying that the thumbnails only create when they have to, for the first time? That would explain some of what I'm seeing, but not all. There were some mass imports from pre-LR days (that I've only glanced at) that this would explain. But on the other hand, there was a 2010 week long event shoot that had lost all its thumbnails and I know I had looked at them all.
Anyway, its really not that big of deal because most of them regenerate quickly. It's the ones that don't generate unless I zoom them that made me write this.

HT1270 Anyone have a MacBook Pro freeze with a beeping alarm sound. What caused this.

Just wondering what caused my MacBook Pro to freeze and have a loud alarm sound. I just installed new memory.

Reinstall the old memory and see if it goes away
If it does then the new memory is bad

What causes "Timed out server" in WL Cluster and a question about session in WL Cluster

          Hi.
          We are using Weblogic 5.1 with SP 8. We have been encountering a problem in our
          clustered environment. We setup our (clustered)environment to have 3 instances(WL1,
          WL2, WL3) of weblogic running in one box. When one instance, let say WL1, responds
          to a request(1st request for a session), the session is binded to that instance
          till the session is terminated/expired. Which means succeeding request for that
          session can only be served by WL1(we tried stopping WL1 but WL2 and WL3 wont accept
          the request--which only causes the page to time out). Shouldnt it behave in such
          a way that other instances can get serve the request(failover)?
          Also, occasionally we encounter "Time out server" in one of the instance of WL.
          When this happens, that instance no longer takes in requests. Would anyone know
          what causes "Time out server"? Does it only happen in clustered environment?
          Need some help ASAP.
          Tnx in adv.


          What do you have in front of WebLogic for Load Balancing?
          What are the IP addresses/hostnames of your three instances? What hostname are
          you using in your http requests? Is your DNS configured to do failover?
          Make sure that you have session replication turned on. See the edocs.bea.com.

How can I find out what causes a program to NOT RESPONDING status suddenly?

After a very long period of functioning without serious problems a program suddenly doesn't start anymore, showing this funny rotating ball and a message in the Activity Monitor that this program is not responding. I have searched the log files meticulously, hoping to find some clues what caused the stuck, but no chance of course. Is there a more or less "educated way" to find out, what happened and how to prevent it in the future?
Thanks a lot in advance

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.

Inconsistency in structure u0093KOMPu0094 - what caused this?

Hi All,
We had a problem where all users experienced an ABAP Dump 'DDIC_TYPE_INCONSISTENCY' when running transaction codes such as FB50.
To solve the problem SAP sent the following instructions:
The problem is due to Inconsistency in the Dictionary for the structure
KOMP. If you go to TCode SE11 : KOMP > Display : Utilities > Runtime
Object > Check -> Active runtime object for KOMP is inconsistent.
To solve this error, please activate the structure KOMP manually by
going to tcode SE11 : enter KOMP > Display : Structure Activate
I have asked SAP what exactly caused this problem and they mentioned that a user had changed underlying structure of KOMP named KOMPAKE.
Tcode SE11 is locked in Production to prevent stuff like this from happening and the only tcode the users ran before we experienced the first dump is KE30.
SAP insists that KE30 could not have changed structure. And the only changes made in production were transports imported 5 days before we experienced this problem.
Would anyone have ideas on how I can determine what caused this problem?
I would appreciate any help.
Thanks,
Kevin

I looked at the version management for this structure KOMPAKE and the only entry I see is from the same user ID with a data/time stamp right before we experienced the first ABAP Dump, and the entry in the version managements starts like this:
Version(s) in the development database:
activ          X 640
I also noticed the same structure KOMPAKE changed in our QA environment by a user that was testing KE30 a day after we had this problem in Production.
So maybe KOMPAKE was auto-generated by KE30 and somehow failed before it could complete, leaving it in an inactive state?
But if that is the case why were there no problems before, can a structure be auto-generated if its already active?
I also found this System log in SM21 where it shows the first ABAP Dump and the errors before it:

How do I delete terminal from my dock, it won't let me open a download. What is terminal and how did I get it on my dock?

Just drag it off the Dock and it will go "poof"
Look at the Options... when you click on it. Unless it got set to stay there, something you did or an app did caused it to be open.
Are there any windows open attached to it?
Is it set to "open on login"?
I use it but I do not have it or keep it on my Dock. It is found in /Applications/Utilities and installers may need to use it.

Thanks for the replies. I reviewed them shortly after they were submitted but I'm also working on other projects at the same time (hence the delayed reply).
Building a time table and doing a cross join to my original resultset gave me the desired resultset of the months assigned between dates. What I can't figure out now is how to filter months I don't want.
Doing a cross join between my original resultset that had two dates:
08/27/2010
10/24/2011
and a calendar table that has 24 rows (each month for a two year period)
my new resultset looks like this:
I need to filter the rows in yellow as the months assigned for stage 3 that started on 8/27/2010 should stop when the patient was assigned to stage 4 on 10/24/2011.
You'll notice that Jan - Sept 2011 isn't listed for Stage 4 assigned on 10/24/2011 as I included a filter in the WHERE clause that states
the Months Assigned value must be greater than or equal to the date assigned value.
Any advice would be appreciated.

What causes cellular data usage to decrease if last reset has not changed? I reset every pay period cuz I do not have unlimited and was showing 125 mb sent/1.2g received. Now showing 98mb sent/980mb received. Last reset still shows same

I reset my cellular data usage every month at the beginning of my billing period so that I can keep track of how much data I am using thru out the month. I do not have the unlimited data plan and have gone over a few times. It's usually the last couple days of my billing cycle and I am charged $10 for an extra gig which I barely use 10% of before my usage is restarted for new billing cycle. FYI, they do not carry the remainder of the unused gig that you purchase for $10 which I disagree with. But have accepted. Lol Moving on.
I have two questions. One possibly being answered by the other. 1. Is cellular data used when I sync to iTunes on my home computer to load songs onto my iPhone from my iTunes library(songs that already exist)? 2. What causes the cellular data usage readings in iPhone settings/general/usage/cellular usage to decrease if my last reset has not changed? It is close to end of my billing cycle and I have been keeping close eye. Earlier today it read around 180mb sent/1.2gb received. Now it reads 90mb sent/980 mb recieved. My last reset date reads the same as before. I don't know if my sync and music management had anything to do with the decrease but i didn't notice the decrease until after I had connected to iTunes and loaded music. I should also mention that a 700mb app automatically loaded itself to my phone during the sync process. Is cellular data used at all during any kind of sync /iPhone/iTunes management? Is the cellular data usage reading under iPhone settings a reliable source to keep track of monthly data usage? Guess turned out to be more than two questions but all related. Thanks in advance for any help you can offer me. It is information I find valuable. Sorry for the book long question.

Is cellular data used at all during any kind of sync /iPhone/iTunes management? Is the cellular data usage reading under iPhone settings a reliable source to keep track of monthly data usage?
1) No.
2) It does provide an estimated usage, but it's not accurate. For accurate determination, you should check the remaining/used MBs from the carrier (most of the carriers provide this service for free).

What causes a slow mouse/cursor response on a fast machine?

I have a system that has always displayed poor cursor redraw performance with certain adobe applications. All rendering and other effects are fast, but basic mouse selections and button knobs are extremely unresponsive. I have searched and searched and can not seem to find out what causes the mouse cursor speed issues. Does anyone have any ideas as to why my mouse would slow for such basic Interface interactions? Do I need to change my hardware, settings, displays, BIOS, etc?
Any insight into what the mouse redraw/refresh is called in terms of computing would help me search for a solution. And if you have a solution as to why my mouse cursor acts drunk and sluggish when interacting with the Adobe UI's in premiere and after effects and sometimes Photoshop I would greatly appreciate the help.
Thank You. I attached a screen shot of a very basic selection interaction that is dog slow. The selection box redraws like there is a lag in some process associated with the square box overlay.

Your answer is in this part of your specs:

It takes a long time to draw and redraw the pixels to the screen(s) with such large monitors.
We can mitigate this by making some changes in how our UI is drawn to the screen, and such changes are a rather high priority for use to work on for the near future.

HT201335 What causes the TV screen to freeze but sound continue on TV when using Air Play from I Phone?

What causes TV screen to freeze but sound continue on TV when using Air Play from I Phone 4?

First try rebooting ATV and router. Beyond that, it's probably something within the network, typically interference.
To get a report of the network go to istumbler (Mac) or netstumbler (PC). Look for signal strength and noise.
If on wifi try ethernet.

What caused the iBook problem?

I'm writing this for my wife, as she's unable to use her iBook for more than a few minutes before it locks up.
I'm serving in the military overseas. My wife and I both use Apple products to chat, email, etc. When I spoke to her yesterday, she was frantic. Her iBook G4 apparently started making a strange noise and then stopped working altogether.
I asked her what she had tried, and she explained that she spent over an hour on the phone with Apple support (I knew AppleCare might come in handy). The first support person she spoke with was, for lack of a better term, an idiot. This was confirmed by the third support person she spoke with. I'll explain later.
The problem was that when she tapped her spacebar to wake up the computer, it didn't wake up completely. She got a grey screen, Apple logo, and that was it. I told her to be patient, that maybe it was reseting after an update (that was before I knew about the 10.4.6 update being available).
Her computer auto-updates every Monday.
I had her turn off the computer by holding down the power button. I then had her disconnect the power cord and remove the battery. I did this on a hunch (just in case the computer had a heat problem). She reconnected the power cord, pressed the power button, and it was back up and running - for about 5 minutes.
Then the computer began making a not-so-funny noise again, and the spinning-beach-ball-of-death reared it's ugly head and wouldn't go away.
The first support person had her use the install/boot disk that came with the computer. That was Panther. We're using Tiger. Bad idea.
When the boot/install disk did not appear to be working, the first support person had her abort, and she was prompted with little phrases like "are you sure you want to quit, doing so now may damage your files" or something like that.
He just had her keep clicking "OK" and eventually got tired of talking to her and told her the hard drive was bad and that she was SOL.
The second support person was apparently too busy to troubleshoot any further and cut directly to "sorry, you're SOL".
The third support person was a little more helpful in that he talked her through connecting the iBook to her G5 PowerPC iMac to attempt pulling the files over to the iMac (she had already resigned herself to the fact that the iBook hard drive was on it's last leg).
She had asked the first support person about doing this and he said that if the files were corrupt on the iBook, they might corrupt the iMac, and that it was a bad idea. Not a very bright guy, considering the files would be copied to a folder, and wouldn't overwrite the iMac's system files.
She started to transfer files and the iBook froze again. She repeated the steps I had her do earlier, managed to get a CD in the the drive, copied a few folder successfully to the CD, checked the CD to see if the files were there (success!) but then the iBook died before she could get the CD out. She's working on holding down the track pad button while rebooting to see if it'll spit out the CD as I type this.
So, in addition to wanting to know how to resolve the problem, I'd like to know what caused it.
What caused so many people to have alleged hard-drive problems within a day or two of each other?
Is this Apple's first virus?
Is this the work of a disgruntled Apple employee working in the updates department?
Is this an evil Apple plot to force us to by MacBook Pro's that won't run Virtual PC?
Will running the 10.4.6 hurt or help the situation?
Why is there such inconsistency in Apple support and aren't they supposed to log their trouble-shooting steps performed thus far?
My wife has been using Mac's for over 9 years. I've only been using them for 2 years. Up until now, I've had a lot of confidence in Apple to be a solid platform, even if not the fastest platform. This experience is not inspiring me to purchase another Apple computer.

Do you have the Tiger Install Disc?
SOL?
Her files probably won't fit on a CD; unless she has less then 700Mb.
1."Is this Apple's first virus?"
Negative
2. "Is this the work of a disgruntled Apple employee working in the updates department?"
No, I don't think so. Apple tries these out to try and avoid problems with their updates. Things happen that are not expected. They wouldn't put anything out unless they thought it was ready.
3. "Is this an evil Apple plot to force us to by MacBook Pro's that won't run Virtual PC?"
First off, look at #1 and think about what platform is notorious for virus problems (Mac has had not had any virus out breaks so far). There have been some "malware/macro" software that was meant to mess with Apple Computers. The most recent that was was over exaggerated was nothing special; MacWorld worked pretty hard to get it to effect their machine. As long as you know what you are downloading and where you are getting it from, you should have no problem.
If you want VPC to work on a MacBook Pro; don't look to Apple. You should talk to Microsoft's Mac Department because Apple announced the Universal Binary switch a long time ago (with developer help) so that software companies could make the switch easier. If anyone is to blame; its Microsoft [they are busy working out their problems with Vista; I am guessing it will be awhile before you see VPC for MBP;) ]
"Will running the 10.4.6 hurt or help the situation?"
My opinion would to just reinstall Mac OS X after backing up the hard drive. That would probably fix your problem. Once OS X is installed; update the software.
"Why is there such inconsistency in Apple support and aren't they supposed to log their trouble-shooting steps performed thus far"
Once in a while Apple's personnel may make human errors. The second one you talked to may have seen her work-up and just reiterated what was said. They have resources we don't, but they can't really go beyond them because they can't see the product, and they are just call support. You may have to send it in.
So in 9 years, you have had this one problem. We can't really tell you what is wrong with the computer because we can't see it ourselves; we can only give suggestions/ideas. Tell them her story, explaining her situation (military etc) and then see if they can help. She may want to bring it into her local Apple Store/Reseller. She can make a reservation on the website or at the store. She can get better feedback in person.
Just some of my thoughts,
