How to Use Google Search More Effectively [INFOGRAPHIC]

Among certain circles (my family, some of my coworkers, etc.) I’m known for my Googling skills. I can find anything, anywhere, in no time flat. My Google-fu is a helpful skill, but not one that’s shrouded in too much mystery — I’ve just mastered some very helpful search tricks and shortcuts and learned to quickly identify the best info in a list of results.
Sadly, though web searches have become and integral part of the academic research landscape, the art of the Google search is an increasingly lost one. A recent studyat Illinois Wesleyan University found that fewer than 25% of students could perform a “reasonably well-executed search.” Wrote researchers, “The majority of students — of all levels — exhibited significant difficulties that ranged across nearly every aspect of the search process.”
That search process also included determining when to rely on Google and when to utilize scholarly databases, but on a fundamental level, it appears that many people just don’t understand how to best find the information they seek using Google.
Thanks to the folks at HackCollege, a number of my “secrets” are out. The infographic below offers a helpful primer for how to best structure searches using advanced operators to more quickly and accurately drill down to the information you want. This is by no means an exhaustive list of search operators and advanced techniques, but it’s a good start that will help set you on the path to becoming a Google master.

10 Google Search Tricks You Might Not Know

1. Boolean Search Parameters
To really master the art of Google search, you can follow certain terms and tricks. For instance, rather than simply asking Google a question in the search box, include specific items such as type of file or title name.

2. Public Data

Google has an entire directory of public data, which you can also access to look up trends. Type keywords such as "population" or "unemployment," followed by a state or county.

3. Easter Eggs

Google's developers have a sense of humor -- just type in "do a barrel roll" or "let it snow" to see for yourself. There are a number of other hidden easter eggs as well.

4. Tracking a Package

If you have the tracking number for a FedEx, UPS or USPS package, type it into the search box and Google will provide you with quick updates on your package's status.

5. Calculator

Need a quick answer to a math problem? Enter the calculation into the search box.

6. Unit Conversions

Wondering how many milliliters are in one cup? Google has a built-in converter for different units of measurement, like height, weight and volume.
You can also do the same for currency conversions.

7. Sports Tracking

If you're on the go, but need a quick check on your favorite sports team, enter the team or league name into the search box.

8. Medication

Find brief summaries and descriptions for most generic and brand name prescription drugs in the U.S. by typing their names into the search box. 

9. Flight Schedule

Whether you need to check the status on a U.S. flight or book a trip, there are a couple terms that can help you plan accordingly.
Enter the name of the airline and the flight number to check its status. To see schedules to or from specific locations, type in "flights from" or "flights to" along with the city or airport.

10. Sunrise and Sunset

Wondering when to catch a sunrise or sunset? If you type "sunrise" or "sunset" followed by the name of the city, Google's built-in feature counts down to the next occurrence.

Google is used by millions of people every single day to resolve any query you could possibly imagine. That being said, it seems there’s a hidden trick or two that even the most skilled in “Google Fu” might not know exists.

Certain tools are built in to Google’s search mechanics to provide quick, reliable answers. For example, if you need to convert a measurement unit, you’ll receive a quick answer at the top of Google search.

To improve your search experience, utilize this list of features to help refine what you’re looking for.

How To Disable Auto Update for Android Market

--------------
Method 1:
--------------
Now the Simple solution that you all must have tried by now is simply go to Settings>Applications>Manage applications>Market and select “Uninstall updates”.
This would uninstall the latest update but the problem is this does not stop the process of market being auto updated in some time.

Here is the solution to this:
#You need to have a rooted android phone.
This can be done with the help of Terminal Emulator. We will have to gain root access and then disable the updater application:

1)Run Terminal Emulator
2)Write the following commands in inverted commas.

“su” [press Enter]

The superuser screen will pop out select Allow

“pm disable com.android.vending.updater” [press Enter]

That’s it,
You will see this on screen and you are done.

“package com.android.vending.updater new status: disabled”

And if by chance things go wrong, or whenever you want to enable updating you can do so by using same commands and using “Enable” in place of “Disable”

--------------
Method 2:
--------------
Here is a simple guide on how to disable Android Market from automatically updating Itself:

1. First root your Android device.
2. Download and install BusyBox from Android Market.
3. On your Android device, tap on Settings > Applications > Manage Applications > Market and on uninstall updates. This will restore your device’s Android Market to stock factory version that it was shipped with.
4. Download, install and launch a terminal app. Android Terminal Emulator is one and you can get it from Android Market.
5. Type in the following command in the terminal emulator app: su (This will give your privileged root access)
6. Type in the following command in the terminal emulator app : touch /data/app/com.android.vending-1.apk
7. Type in the following command in the terminal emulator app: chattr +i /data/app/com.android.vending-1.apk

If done correctly, the above steps will disable auto updates for Android Market.

What this process basically does is put a bogus APK file in the way of where Android wants to put the new version. The chattr command makes the file “immutable”, so that even root can’t remove it. Just setting it read only with chmod isn’t enough.

--------------
Method 3:
--------------
NOTE: Phone must be rooted and have super user rights.

1. Go into your system/app folder and rename MarketUpdater.apk to MarketUpdater.apk.bak. (I would suggest a rename instead of deleting the apk)
2. If the market has already updated, after doing step 1, go to Settings > Applications > Manage applications.
3. Scroll down to Market, click on it and choose Uninstall updates. 

Done. No more market update.

Fixing The "Couldn't Install On USB Storage Or SD Card" Problem On Android

Today, for the first time ever, my Android had an unexpected failure installing updates for some of my Android apps. All update attempts would inevitably end in an almost instant failure with the message that read:

Installation error
Couldn't install on USB storage or SD card
snap20110418_235450
The weird part was that some apps installed OK but some got stuck in a perma-fail mode and could no longer be updated. After mucking around for a bit, I dug into the logs and found the following relevant log line: 

Failed to create secure container smdl2tmp1
Aha! Now what the heck is smdl2tmp1?
After digging around the Internet some more, I found that the problem is caused by a temporary file called smdl2tmp1.asec that is used during some installations (I think of apps that are movable to SD) but does not get deleted for some reason, most notably when you run out of space. Because of this, the system can't create it and treats it as an error, rather than figuring out that it's stale and simply deleting it.
The solution? Go and delete smdl2tmp1.asec yourself. From what I can tell, it could reside in 2 locations:
1. /sdcard/.android_secure - this is an invisible folder on your SD card, which you can access with any file manager, like ASTRO
2. /mnt/secure/asec/ - access to this folder requires root and a program like Root Explorer
Look for smdl2tmp1.asec in these folders and delete any ones you see. Deleting it seems to be a safe enough operation - it's just a temporary file after all. Once you've done that, all the update problems should go away: 

I/logwrapper(  170): /system/bin/newfs_msdos terminated by exit(0)
I/PackageHelper(15175): Created secure container smdl2tmp1 at /mnt/asec/smdl2tmp1
I/DefContainer(15175): Created container for smdl2tmp1 at path : /mnt/asec/smdl2tmp1
I/DefContainer(15175): Copied /cache/32.apk to /mnt/asec/smdl2tmp1/pkg.apk
I/DefContainer(15175): Finalized container smdl2tmp1
I/DefContainer(15175): Unmounting smdl2tmp1 at path /mnt/asec/smdl2tmp1
Later on, I found this bug discussing the situation and slamming Google left and right for not fixing this problem and requiring users to look for random files on their phones, which I wholeheartedly agreed with.
Oh well, at least my phone is healthy again, and I hope yours is too, as you probably found this page while looking for a solution.
