How does Google know my city

Ok, I hope to god this is not a ******** question, with an obvious answer. How does google know to look for certain stores, lets say Barnes and Noble, only in my vicinity? I haven't set any preferences for it. Is it based on my registration with apple?

I don't know for sure, but I think that Google does some location awareness based on the rough location through which your IP address is routed.
There exist many geolocation maps on the internet that map your IP address to an approximate location for you. That plus Google's massive search engine, and the difference between Renton, VA and Renton, WA becomes apparent, at least to them.
I've seen limited forms of this even on other devices, where Google automatically routed me to a mobile version of their site, and localized to the approximate area it thought I was in.

How does Google know what I am searching Bing for?

How in the world do Google ads appear in Safari for items I searched Bing for?

There are some easy steps you can take to enhance your privacy on the Web.
From the Safari menu bar, select
Safari ▹ Preferences ▹ Extensions
Take an inventory of the extensions you've installed, if any. Some Safari extensions are adware or spyware. Read the privacy policies or terms of use carefully. Remove any that you don't really need or aren't sure about.
One extension that you may want to install is called "Ghostery." It blocks many tracking cookies. But there are reports that it sometimes causes Safari to crash. I use it and have had no problems.
If you've installed any ad-supported hacks such as "Glims" that modify Safari, uninstall them according to the developer's instructions. Doing so will enhance the stability of Safari, as well as your privacy.
In the Safari preferences dialog, select the Privacy tab. You have the option to remove data, such as cookies, stored on your computer by web servers. You can remove all such data, or remove only some of it by clicking the Details button. The other settings are pretty much self-explanatory.
On a more advanced level, you can change the DNS servers used by your computer, or your router, to look up the addresses of all Internet servers that you use. In general, the best choice from the standpoint of privacy is to use your ISP's DNS servers. Your Internet traffic goes through your ISP's network anyway, so in theory there's no loss of privacy in using its DNS servers. Avoid third-party DNS services such as "OpenDNS," which is in the business of selling information about you to marketers.
Consider using ad-blocking software such as "GlimmerBlocker," which also blocks some forms of JavaScript abuse that can be used to track you. It's only suitable for advanced users, and it may block some web content that you want to see.
When using a public network such as a Wi-Fi hotspot, keep in mind that others connected to the same network may be able to eavesdrop on your network traffic. They won't be able to read the contents of that traffic if you connect to secure websites such as this one, but they will know the addresses of the sites. The same goes for email and messaging. Some public VPN services market themselves as a solution to this problem, but using those services may have serious security and privacy implications.

How does oracle know which AO Framework page or process to execute.

Hi,
How does oracle know which AO Framework page or process to execute. I use to think this was defined in the Function definition. But looking through some Function definition in HRMS setup I noticed some of them simply calling the same first page, such as the one below used in many managers menus. This initial page is the page that allows managers to choose the employee they want to work on.
OA.jsp?akRegionCode=HR_PERSON_TREE_TOP_SS&akRegionApplicationId=800.
My question is, after executing this initial page, how does Oracle then varies the OA page by the diffferent functions?

Hi;
Thanks for sharing
Please dont forget to change thread status to answered if it possible when u belive your thread has been answered, it pretend to lose time of other forums user while they are searching open question which is not answered,thanks for understanding*

How does Siri know where my office is

Ok I just got my iPhone 4s and I can't work out how to get Siri to remind me to do something when I get to the office.
How does Siri know when I'm at the office
How does Siri know I'm at home
How does Siri know I am at a particular place.
I know how to get Siri to do a reminder by using time, but the adverts say "office" so how does it know
Any help appreciated for a new 4s user :-)

Put your office location in your contacts by itself with a label of office or work. Or associate it as office or work like you do with wife and kids and such.

How does j_security_check know which page to redirect to?

Hi All,
I have implemented j_security_check in our weblogic web app successfully.
What I would like to know is following the authentication and authorization via the container, how does it know to redirect the user to index.jsp?
For example, we have login.jsp which contains the j_username and j_password fields, and the action is j_security_check. After the user hits submit and the container authenticates them, how does it know to then direct them to index.jsp? Is it because the welcome tag in web.xml is set up to direct them to index.jsp?
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
Thats the only thing i can think of!
Thanks in advance.

That's correct.
You are specifying a login page, which will ONLY be accessed when the user attempts to view a secured resource.
After logging in, they will see the page they were originally trying to get to.
They will only be forced to go to the login page if you secure the page they are trying to get to:
<security-constraint>
     <web-resource-collection>
          <web-resource-name>Resources</web-resource-name>
          <description>Require users to authenticate</description>
          <url-pattern>/upload/filelist.jsf</url-pattern>
</web-resource-collection>
<auth-constraint>
<description>Define who can access this url-pattern</description>
<role-name>NTSB Users</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>FORM</auth-method>
<realm-name>dot-ad</realm-name>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/loginError.jsp</form-error-page>
</form-login-config>
</login-config>
<security-role>

How does WebLogic know it needs XA transaction?

I've been informed that Weblogic 8.1 "knows" whether it needs to start a global XA transaction or not when it starts a transaction...sparing the overhead of an XA transaction if it is not needed.
          Is this a true statement?...and if so...how does it know that distributed resources will be used in the transaction when it is starting the transaction?
          The main reason I ask is that we are wondering if there is any way to avoid using the XA driver for "every" transaction, when we only need it less than 1% of the time. We would like to avoid the overhead that is introduced with XA.

WebLogic always performs XA operations, it looks at the resource and checks if it implements the XAResource interface, if it does it uses the XA operations with that resource otherwise the operations will just be a null op.
          So it depends on what resources you use in the tx. If you mix, XA and Non-XA resources in the tx, you may hit heuristic exceptions and inconsistentcies in your data which you will have to manually correct. Also you loose the ability to recover any transactions.

How does apple know what the fault is with my iphone?

How does apple know what the fault is with my iphone when sending it to them on apple care. My sleep/ wake button seems to be stuck so I sent in for a repair on the website and they sent me a apple care box and said send it back but I Carnt remember if I told them the fault or do they know by the repair ID number? Please help as I'm sending it off in a couple of day.

Include a note in the shipping box describing in detail the issue you have with the phone. Include your name, address, phone number, email, iPhone model and serial number, and a detailed explanation of the problem.

How does pacman know how to remove packages?

I've been looking at the 'Creating Packages' page, and it says to create a pkgbuild I only need to specify the build function. My question is... how does pacman know which files to remove when you do pacman -R? Does it keep track of all the files that were installed via build()?
Second question: How do you guys keep track of packages that weren't installed via the AUR? For example, if you want to hack on a project and use that hacked copy instead of the one available in the repos, what do you usually do? I'm guessing that I should let pacman keep track of those by creating pkgbuilds for them, naming them something like [packagename]-[version]-myown, and noting that it conflicts with the package in the Arch repos... is this correct?

When you build a package with makepkg, the build function is responsible for installing the files that will be contained in the package under ${BUILD_DIR}/pkg. That directory will be tar'ed and compacted to make your final package. When you install it with pacman, will be created the file /var/lib/pacman/local/<name of your package>/files which will list all the files owned by your package. So pacman can know how to remove them when you ask it to be deleted.
About your 2nd. question, you are quite right. The only correction is that the name of your new package should be something like "package-myown-version". You should put the old name in the conflicts and provides directive of the PKGBUILD. You should read the wiki about ABS. With it, you can get a copy of all PKGBUILDS for your current repositories, so you can change what pleases you more.

How does oracle know the databse is inconsistent and needs recovery?

Hello,
How does Oracle know that the datafiles are inconsistent and db needs recovery when rebuilding the db off of the online/hot backups? Whereas, it doesn’t ask for recovery when rebuilding the database from cold backup (I understand that, for cold backup, database is shutdown immediate and hence the db is consistent). In both scenarios, a new control file is created (that means it won’t have SCN) and only datafile header will have the SCN. What’s that piece of info that oracle check to know if the database is consistent or inconsistent during the backup restore and recovery and where that info resides?
Thank you for any hints and answers.
Jay

Oracle uses the datafiles to identify if they are consistent. If the datafiles backup was taken when the database was OPEN, they are marked as "fuzzy" in the header. Also, likely, the Checkpoint SCNs may be different if tablespace checkpoints (e.g. by ALTER TABLESPACE BEGIN BACKUP) are at different points in time.
If the backup was a cold backup with the database shutdown normal/immediate, the headers are marked appropriately.
When you run CREATE CONTROLFILE, it has to read the datafiles because the controlfile, itself, has no SCN and LogSequenceNumbers information.

How does one know whether or not they use "Java applets"?

The support doc for the recent Java update (Update 8, for Snow Leopard), entitled "About Java for Mac OS X 10.6 Update 8," advises the following:
If you do not use Java applets, it is recommended that you disable the Java web plug-in in your web browser.

Sometimes you have to dig to find out: http://earthnow.usgs.gov/earthnow_app.html
doesn't tell you directly, but it is mentioned in the FAQ that Java is required. If the content is appropriate, you can always ask here.
Thanks. According to that webpage, my "Java is out of date." When an error message like that is returned, I guess it's clear that "it's a Java problem." Presumably, one would then just go to java.com and download the applet if he/she wanted to view the webpage.
I was wondering more about situation when unexplained problems that involved missing Java applets weren't noted in error messages.
But maybe I'm worrying about something that doesn't really need to be worried about.

How does he know ? (pacman and package names)

i take a package from pacman cache on box 1
i rename it from say xorg-1.4.0.pkg.tar.gz to xorg14-1.4.0.pkg.tar.gz
i pacman -U it on box 2
pacman on box 2 : upgrading xorg ###############33
how does he know its xorg and not xorg14 ? (there seem to be only the actual files of the application inside)
how do i rename the package so that pacman really understands its xorg14 and not xorg ?

several reasons
i hate ignorepkgs (and the trouble they can make if some dependency escapes out of what you ignorepkg'd)
i have multiple (varying between 5 - 9) boxes that run arch + 3 family / friends boxes with arch that i am the support guy for. when a bad or unexpected update was out (dhcpcd kde4 xorg lib/include/asm etc) it was bad for most or all of the boxes - so i want a solution for all at once
i install from scratch a lot (i naturally have skill of breaking my system to irrecoverable state and with the recent updates of arch its even more cause i swap hard drives). i prefer to have a custom mirror on my usb flash drive
i want to be able to give this mirror easily to others too - like that guy that made the kde 3 mirror

How does one know if they use "java applets"? What do they do? How will I know if I need to 'disable the java web plug-in browser' if I do not use them? (Obviously I'm not very literate in computer-speak.)

Well, when you go to a web page a section of the web page will have a coffee cup picture where the java applet will run. The applet loads then runs. If you are not seeing this behavior then you are not using java. If it make you feel more comfortable then disable the browser java plugin. On my machine I have not disable java- but you
may what to.
