How to find out what the latest update is for something from apple's site?

i've never been able to do this, and has been a recurring problem for many years:
how can you, using apple's web site -- presumably the support or downloads section -- find out what the latest update for/of a certain product is?
without going into the details, the software update app is of no use to me.
for example, i have a airport extreme base station 54 mbps. how do i go about finding out what it's latest software is? do such products not have a web page which has the latest update linked to from it?
why is it so hard, impossible i find, to find out what the latest software is?
any pointers much appreciated. (i'm not particularly looking for the answer to "what't the latest update for a airport extreme base station 54 mbps?" but a general method for finding out the latest update for anything using apple's web site)
thanks very much.

If you use the Advance Search function:
http://search.info.apple.com/
you can filter results to give downloads for the search words airport extreme base station. The return will be in date order from newest to oldest. Yo ucan also designate word pairs of groups to narrow the search.

How to find out what the authentication is for

This is a general info-sec-related question applicable to all recent OS X versions.
Occasionally when I'm doing things on my Macbookpro running Mavericks I get a dialog that I'm sure all of us have seen. It says something along the lines "[Some program] wants to make changes to the system. Enter admin password to authorize."
How do I find out what exactly I am giving permission for when entering admin password? How do I know which restricted resource [Some program] is trying to write to? Is there an advanced user view of that dialog?
It just doesn't seem fair to have the choose between failing the task I'm trying to accomplish by canceling and giving some shady program, basically, root access by giving it admin password.

Boooooo thumbs down for that answer: completely useless, counter productive, diverting discussion away from solving the problem towards pointless discussion of what I should've known and not known. Please refrain responding unless you have comments that are constructive. We can discuss the theory of UI design after this problem is solved.
Here is a specific example showing how diverse range of issues affected by the problem is. I just ported a copy of Ableton Live to another account my Mac. That includes several complex sample libraries and configuration folders. Since they used to belong to the other account, the ownership and permissions of all of the was super messed up. I fixed most of permission issues before firing up any big projects. A typical project references hundreds of files. At some point while working on one of the typical project the dialog saying "Live wants to change your system. Enter password if you authorize." Pops up. How do I find out which resource has broken permissions without the prohibitively expansive trial and error linear search of all possibilities?

Laptop's freezing: how to find out what the problem is?

Hi all,
First of, I realize that this is not the best forum to ask about hardware
issues, but that's not *exactly* what my question is, please read on!
So, my laptop started freezing at seemingly random times. I understand
that this could be a hardware issue, but I was wondering if there is any
way I can find out something. For instance, I tried to have htop running
constantly so when the laptop froze I checked if any stats where weird,
but there wasn't any problem that I could see.
Any other ideas on how I could possibly get an idea what's wrong?

When it freezes:
Do the keyboard lights flash?
Can you SSH into the box?
Can you ping the box?
Does it unfreeze? Or does it require you shutdown and reboot?
If it unfreezes, was the disk access light on during the freeze?
Is there anything interesting in the logs or journals after your reboot?
Other things you can try:
Blacklist kernel modules of all non-essential hardware and see if that improves stability.
If it does, turn them back on, one at a time.
Is it temperature related? Check both ambient and core temperatures.
Is it susceptible to mechanical shock?
Have you run a memory test?
Does it only freeze when on batteries?

How to find out what the latest version of IOS I can use?

I am using Cisco Switch 2950 with IOS 12.1(9)EA1. I want to download the latest IOS to upgrade it. How can I from the Cisco Website find out the latest IOS and download the software?

Hi,
The switch may be old one and out of support. first check the End-of-Sale/support information here:

How to find out what the underlying table/query of a form in Oracle Apps.

Hi
I am trying to find out who owns the underlying objects of a query when a user runs the Transactions > Line_Items form for Receivables .
I have selected Help > Record History but I get a message Record History not available here.
The query is running slow and I'd like to see if the objects have been analyzed lately.
Thanks
Andy

Hi
I should have said in the ticket that this is version 11.5.10
It was close to giving me the answer I need. It gives me the following details. Unfortunately it doesn't give me the underlying sql. I hhave tried using v$session and sys.v_$sql but the sql is over 1000 characters long so I dont get to see the table/object being referenced.
I appreciate the feedback.
Thanks
Andy

How do I find out what the correct tag information is for a TV series I purchased through the iTunes store?

Right now I have episodes that should be in their own grouping mixed up with others and I would like to get them seperated. It's the Doctor Who series if that makes a difference. Specifically the specials which don't quite fit into a season and were a seperate purchase from the series themselves.

I'm confused. Who told you that you need to deauthorize an Audible account to be able to play your music? Did you ever set up an account with Audible.com? What is happening when you try to play your music? And what exactly do you mean by "sync your iTunes account with your laptop"?
Please provide more details as to your situation and what it is you're trying to accomplish. I'm sure once we understand what it going on, someone can provide suggestions.
Regards.

How do I find out what the name of the reports server is?

Hi Everyone,
I am connecting to a remote machine using gotomypc.com and have started up Reports Builder 10g. I know very little about installation of Oracle on this machine. Just enough to log into Oracle 10g and run tools like the Report Builder, TOAD, etc. When I run a report from the Report Builder I get a web browser with a blank report. It works when I run a paper report. I am guessing that the Reports Server is not running or not configured properly.
Can you tell me how to find out what the name of this Reports Server is and/or how to start it up?
Thanks.
Emad

I realize this is old, but... You can find out your servers name by looking at the $ORACLE_HOME\reports\conf\rwservlet.properties file. It has a entry for SERVER. Should also have a corresponding conf file after starting up OC4J and activating the server for developer installs.
Next, you can also run rwdiag. It will show you all report servers available to your installation. This is interesting when Multicast is used by Reports (10g). Ran into issues with servers named the same not on the hardware I was expecting.... ;)
Good luck.
