How do I find out my monitor's resolution?

I want to make a wallpaper for my mac connected to a Dell monitor. How can I figure out what size to make it?
Thanks

Open the Displays pane of System Preferences. If you can't get it from there, take a screenshot, select the png in the Finder, choose Get Info from the File menu, and look at the More Info section.

How do I find out what applications are running in the background

I have a 2008 iMac with 2GB memory. How do I find out what programs are running in the background? I am going to buy a new iMac before the end of the year to replace this one. When I looked at Activity Monitor it shows 1.8Gb used but doesn't tell all the programs running.

open activity monitor [if it doesnt launch click winders>Activity Monitor]. then it'll show all proceses

My MacBook Pro is running very slow. How do I find out what is causing this?

How do I find out why my MacBook Pro is running so slow? Then how do I fix it?

Suggestions of Things You Can Do To Help A Slow Computer
If your computer seems to be running slower here are some things you can do:
Start with visits to:     OS X Maintenance - MacAttorney;
                                  The X Lab: The X-FAQs;
                                  The Safe Mac » Mac Performance Guide;
                                  The Safe Mac » The myth of the dirty Mac;
                                  Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
          Mac OS X Snow Leopard and malware detection
          OS X Lion- Protect your Mac from malware
          OS X Mountain Lion- Protect your Mac from malware
          About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
    used to manage backups and to restore backups. Time Machine
    requires a backup drive that is at least twice the capacity of the
    drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

How do i find out the speed of file transfers

Hi all, first i have to admit i dont actually have a Time Capsule, i have a Western Digital MyBookLive with which i backup my MacBookPro using Time Machine.
I have also upgraded my Router to one with Gigabit LAN, my MacBookPro is gigabit and so is my WD MyBookLive gigabit !!!.
I already realise that file tranfers can in NO WAY can get anywhere near gigabit speeds, but, neverthless how do i find out how fast my gear does transfer files ?.
I am currently backing up using TimeMachine using a wire, i would like to see the actual difference between Wired and Wireless transfers.
Any suggestions would be very much appreciated !. thanks for looking.

woweee, thanks for that buddy, i should have thought of that, thanks.
I bet you guessed it already ?.
Can someone explain all the information shown in the Activity Monitor
I have the Network Tab selected: i have Data recieved at anywhere between 100 and sometimes as high as 400
whereas data sent is always under 10 !
peak is about 8 so does Data sent refer to to My Time Machine Backup GOING TO my Network Hard Drive ?
if so where is the Data recieved stuff, going to or coming from ?. it is all a bit confusing for me, i think i better go back to bed and lay down LOL.

How can I find out what port number my DB is using

How would one find out what port number a database is using? Is there a SQL command that will allow us to do this?
Thanks,
oracle_newbie

newbie
Oracle databse assigns a dynamic port number for each established session. Usually, the common port is 1521 which is defined in you tnsnames.ora, however, this is used for requesting a dynamic port. Dynamic ports are within a ragne of 1000+. That's why it is hard to tell which port you are using at a certain time. You should have a network monitoring tool to check this accurately.

i'm not entirely sure about the new tab page - in principle it will use an algorithm which populates the slots based on the frequency & the recency of visits. however i think that sites removed from the history should also disappear from the new tab page (when i tried it it was at least true after i've restarted the browser once) - if this isn't happening for you then it might be some bug...
in any case firefox won't have the proper features to reliably monitor your kids' browsing behaviour - they always can use private browsing mode where no traces will be left on the pc or manually "clean up" the history.

ADS problem: How can I find out the SP of ADS?!

Hi,
when i try to run the Dynamic Form tutorial i get the following exception:
java.net.SocketTimeoutException: Read timed out
The execution of "Test" under http://<host>:<port>/AdobeDocumentServices/Config
was successfull.
I have SAP Developer Studio SP 11, J2EE SP11, but I am not sure what ADS SP I have.
So my question:
Is it important that the ADS has the same SP than the J2EE and the Developer Studio?
And how can I find out what ADS version I have currently installed?
Kind regards,
Tobi

Hi Tobias,
This can be due to lot of reasons.
Please have a look at the following SAP Notes:
826419 Setting socket timeout for WS Clients in SP10 and SP11
849851 Importing a Web Dynpro patch for Support Package 12
867502 Read Timeout using AdobeDocumentService in Web Dynpro
Also there are few more notes, that you should check.
To check the version of all the components in your J2EE Engine, goto
http://<server>:<port>/sap/monitoring/ComponentInfo
You can see the version of Software Components.
For ADS check ADS_SAP and ADS_SAPOFF components version. It will be like 1.00 SPXX.
Let me know if you still got this problem.
Regards,
Shubham

How can we find out data in an editable ALV grid has been changed or not?

Hi Experts,
How can we find out whether a data in an editable ALV grid has been changed or not.
I am using the
FM -> REUSE_ALV_GRID_DISPLAY_LVC
for ALV display.
I have to chekc whther data has been changed or not befor saving. if changed then only i want to
SAVE
. I cannot use the internal table comparison method for this purpose also i am not using OOP ALV.
So kindly sugest me an alternative.
Thanks and Regards,
Shahana

Hi,
Thanks for your answer. I already saw this post.
See this method.
CALL METHOD reuse_alv_grid->check_changed_data
IMPORTING
e_valid = lv_check.
This will update the internal table with the edited values. Then we can go for internal table comparison.
But my scenario will not allow me for itab comparisons.I just want to know the ALV data has been changed or not.
Regards,
Shahana

I want to update my phone, but i purchased many apps and music on the phone. it won't let me authorize my computer so i cannot update. i don't want to deauthorize all my computers. how can i find out which 5 computers i have authorized?

i want to update my phone, but i purchased many apps and music on the phone. it won't let me authorize my computer so i cannot update. i don't want to deauthorize all my computers. how can i find out which 5 computers i have authorized? also how can i update the software?

This is a tedious solution, which is stupid! And some users report an inability to reauthorize a computer after an "en masse” deauthorization. I can’t believe Apple doesn’t provide a list or menu to find out which computers you’ve authorized! Obviously, APPLE knows (or else they couldn’t tell us how many computers we have authorized)--so why can’t they give us access to that information about our own computers??!!!
And for an already-authorized computer with a hard drive that’s since been replaced and upgraded from Mavericks to Yosemite, would it be recognized as a “new computer” and require authorization? Would its previous incarnation (i.e., with the old hard drive and OS) be considered a separate computer? Some users report they can’t authorize a computer after an OS upgrade because of that. Can’t believe we have to do such a bass-ackwards kludge!
