What does it mean when the power up light just blinks

issue with the boot drive? I was going to start up from disk warrior but can't even get the cd drive to come out
no start up sound, monitor won't come on
someone brought this Mac pro 2 to me to get some files off of it. I have not worked with one of these
any help?

On a Mac laptop the flashes usually indicate a problem with RAM; the document linked to seems to agree. On the portables it can mean the RAM is not properly inserted. Try reseating the RAM on the RAM cards. Since the machine was brought in, maybe something came loose during transport.

What does it mean when the error code says:

what does it mean when it says: cannot get mail-connection to server failed?
I'm talking about my Ipad 2

It means that the iPad cannot connect to the company that serves your email to you.
This can be cause by incorrect settings on your iPad. But if you were able to get mail regularly iprior to this on your iPad it could be a problem with your email provider that is causing the problem.
We're you able to get your email previously with the same device?

Is the hold switch in the on position? Try resetting the iPod. To do this, press and hold both the Select/Center and menu buttons together long enough for the Apple logo to appear. The iPod may have simply locked up.

What does it mean when the usecounts of Parse Tree for a view is incrementing when a select query is issued against the view?

I'm using SQL Server 2008 R2 (10.50.4033) and I'm troubleshooting an issue that a select query against a specific view is taking more than 30 seconds consistently.   The issue just starts happening this week and there is no mass changes in data.
The problem only occur if the query is issued from an IIS application but not from SSMS. One thing I noticed is that sys.dm_exec_cached_plans is returning 2 Parse Tree rows for the view - one created when the select query is issued
1st time from the IIS application and another one created when the same select query is issued 1st time from SSMS.   The usecounts of the Parse Tree row for the view (the IIS one) is increasing whenever the select query is issued.  The
usecounts of the Parse Tree row for the view (the SSMS one) does not increase when the select query is issued again.
There seems to be a correlation between the slowness of the query and the increasing of the usecounts of the Parse Tree row for the view.
I don't know why there is 2 Parse Tree rows for the view. There is also 2 Compiled Plan rows for the select query.
What does the Parse Tree row mean especially the usecounts column?

>> The issue just starts happening this week and there is no mass changes in data.
There might be a mass changes in the execution plan for several reason without mass changes in data
If you have the old version and a way to check the old execution plan, and compare to the new one, that this should be your starting point. In most cases you don't have this option and we need to monitor from scratch.
>> The problem only occur if the query is issued from an IIS application but not from SSMS.
This mean that we know exactly what is the different and you can compare both execution plan. once you do it, you will find that they are no the same. But this is very common issue and we can know that it is a result of different SETting while connecting
from different application. SSMS is an external app like any app that you develop in Visual studio but the SSMS dose not use the Dot.Net default options.
Please check this link, to find the full explanation and solutions:
http://www.sommarskog.se/query-plan-mysteries.html
Take a look at sys.dm_exec_sessions for your ASP.Net application and for your SSMS session.
If you need more specific help, then we need more information and less stories :-)
We need to see the DDL+DML+Query and both execution plans
>> What does the Parse Tree row mean
I am not sure what you mean but the parse tree represents the logical steps necessary to execute the query that has been requested. you can check this tutorial about the execution plan: https://www.simple-talk.com/sql/performance/execution-plan-basics/ or
this one: http://www.developer.com/db/understanding-a-sql-server-query-execution-plan.html

What does it mean when the dialogue box that pops up when you want to bookmark a site says " Remove 3 bookmarks?"

Using Firefox 17.0. When I click on "Bookmark a Page" under the star in the dialogue box that appears it may say "Remove Bookmark" or "Remove 3 bookmarks." What does it mean - will it really remove three bookmarks?

'''Try the Firefox Safe Mode''' to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.''
''(If you're not using it, switch to the Default theme.)''
* You can open the Firefox 4.0+ Safe Mode by holding the '''Shift''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Don't select anything right now, just use "'Start in Safe Mode"''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.''
'''''If it is good in the Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one.

What does discard mean when the NewAsyncTimer functions count elapses?

I have a PXI system with a PXIe8101 controller running with a real-time OS. I am having trouble with the asynchronous timer. I have a question about the count parameter in the function NewAsyncTimer(). The documentation says " Specifies teh number of timer events to be generated before the timer is automatically discarded."
What does it mean by "discarded"?
Does this mean it is "discarded" like when you call the function DiscardAsyncTimer() and it removes it from the list of existing timers?
Another question?
I created my timer like this:
gRegCalMainLoopID = NewAsyncTimer (1e-03, -1, 0, RegCalProcessCntrlLoop, 0);
I belive this will set the priority to THREAD_PRIORITY_HIGHEST (2).
Since I set the initialState parameter to 0 it should not make call the call back function until I set teh ASYNC_ATTR_ENABLED to 1.
I send a command to do this and it makes this call:
  timerStatus = SetAsyncTimerAttribute( gRegCalMainLoopID,ASYNC_ATTR_ENABLED,1); // this starts the timer interrupt
My problem is the timer function is never called with teh event = to EVENT_TIMER_TICK.
Here is my timer callback function:
int CVICALLBACK RegCalProcessCntrlLoop (int reserved, int timerId, int event, void *callbackData, int eventData1, int eventData2)
switch(event)
  case EVENT_TIMER_TICK:
The only other timer I have running in my system is in RTmain(). But it should be at a lower priority so the higher priority timer callback should not get blocked.
Her is part of my RTmain()
void CVIFUNC_C RTmain (void)
if (InitCVIRTE (0, 0, 0) == 0)
  return;    /* out of memory */
/*************************** Initialization code. ****************************/
gDone=0; // when it is set to one the application is exited.
// create callback timers
CreateCallbackTimers(); // here is where I call the NewAsyncTimer() function above
// initialize DMM digital multi-meter
init_dmm();
init_pxi_gpib();
/*********************** END OF Initialization code. *************************/
while (!RTIsShuttingDown () && !gDone)
  /* Your code. */
  /* Sleep for some amount of time to give the desired loop rate */
  /* and to allow lower priority threads to run.                 */
  SleepUS (100);
  ProcessSystemEvents ();
Any ideas what might be going on?

Hi DPearce,
It does seem that the timer will be discarded in the same way as DiscardAsyncTimer meaning that the timer will no longer be registered or active after being called a specific number of times. Is there a specific aspect of the count parameter that you are curious about?
For Real Time systems a priority level of 2 is not necessarily the Highest Priority Thread and more information can be found in the help topic NewAsyncTimerWithPriority.
Have you seen if you are able to capture the Event Discard event as well?

What does it mean when the "time connected" disappears?

I am using a Time Capsule plus a couple of Airport Express devices to extend my wireless network. I have various MacBook models. On all my MacBooks, the "time connected" clock keeps on disappearing, sometimes 5 or 6 times a minute. The clock comes, then it goes, then it comes back... What does this mean? If it is bad, any suggestions how I fix it?

Something is wrong.
Open the airport utility and click on the yellow light in the summary page. it will take you to the errors.
Likely needs a firmware update.
Which maybe worth avoiding.
