Filter Tweets In Twitter Web Interface

is a place for everyone to communicate their feelings with no one in particular. However, at times some people you follow could go on a tweet rampage or there could be a barrage of tweets for some #hashtag which can get annoying. Unfollowing those people is an easy option to stop seeing their tweets, but what if you could just temporarily not view those tweets from a person or for a #hashtag on your timeline?


Desktop software like already provide you with an option to filter tweets, however, it you cannot do it on the web though. Twitter Filter is a handy for which allows you to temporarily filter out tweets from certain users in the web interface. 

As you can see from the screenshot above, this extension will allow you to exclude tweets that contain a certain #hashtag, as well as tweets from one or more people. This is a great way to temporarily hide tweets instead of using the Unfollow button.


users can make use of some scripts to filter out tweets from your Twitter web timeline. You can install the Filter Tweets script for Greasemonkey and use it to filter out keywords or people’s tweets from your timeline temporarily. One benefit of using this script is that you can also filter out all tweets which contain links.

This script can also be used on Chrome, and Internet Explorer. You might want to read our earlier tutorial on installing Greasemonkey scripts in Opera, IE and Safari.

P.S. I have only tested these scripts with the #newTwitter interface. I am not 100% sure about it working with the older one.

View Google AdSense Earnings for Different Geo-locations/Countries

is no doubt one of the biggest ad networks which is used by millions of websites. Google AdSense’s reports are real-time and provide a comprehensive view of the impressions and number of clicks a website generates. However, one important thing missing in Google AdSense is geo-location based reporting which will help a webmaster to know how AdSense performs in different countries.

Don’t Miss: Useful Tips and Tricks To Grow Your AdSense Income

In my experience, knowing country wise performance of advertising networks has helped me to replace certain ads in certain countries with higher performing ones, thus helping me increase my revenues. I do that using Google DFP, for which I am writing a guide, you might want to know the benefits of using Google DFP too.

Coming back to the topic, is there a way to find AdSense performance based on geo-location? Yes, there is, using Google Analytics. Before you use this trick, there are two requisites:

  1. You have to use Google Analytics for your site. If you don’t sign up here.
  2. You have to link your Google Analytics and Google AdSense accounts. If you don’t know how, read this help forum topic.

If you fulfill both of these requirements, dive straight into knowing the performance of Google AdSense based on geo-location below. If not, you will have to wait a few days before you can start seeing this data.

Google Analytics Map Overlay

To see how AdSense is performing in any country, head over to your analytics account and view the analytics for the site you want to get this data for. Click on the “Visitors” link in the right hand side and then click on the “Map Overlay” link.

Google Analytics Country Breakup

On the Map Overlay page, scroll down till you see links for the countries and click on the country you want to see the AdSense performance for. Once you do that, you will see a city/region wise breakup for that particular country.


In the country view, click on the “None” dimension link and select any of the dimensions from the available list. You can click on any one of them. Once you do that a new report will load based on that dimension.

On this page, you will now see an additional tab which displays the AdSense revenue for that particular geo-location or country to you. This data might be an estimate but it does provide you with a way to check on how AdSense is performing in a particular country, city or region.

Google Analytics Country AdSense Revenue

With this data in hand, you can easily replace Google AdSense units with higher performing ones in those countries. Of course, everything is trial and error so you have to make your own judgments here. However, hopefully this guide should help you target your ads better and maximize your revenues.

Fix Chrome 9.0.597.0 dev Channel Crashes, GPU Acceleration Crashes

If you upgraded to version 9.0.597.0 dev this morning and are seeing frequent crashing of the browser, you are not alone. The problem is that the latest version of Chrome has a problem with the GPU Acceleration.

Thanks to How-to-Geek there are several solutions to fix the GPU Acceleration crashes on dev channel. The one that worked for me is adding "–disable-accelerated-compositing" switch to the command line and start it again.

This problem occurs for only those users who have turned on GPU acceleration in about:flags (previously about:labs), so you might want to go there and disable "GPU Accelerated Canvas 2D" feature for the time being and then try starting the browser without the above switch.

If the command line switch does not fix your problem, you will find more solutions at the how-to-geek’s post linked above.

How To Verify If An Email Address Exists

There are times when you will receive an email from someone you were not anticipating communications from and then jump out of your seat because you received a good news. However, it could be that someone is playing a prank with you and the email address for that user might not even exist.

Of course there are ways to determine whether an email is fake or not by looking at the email headers, but what if you want to verify whether an email address exists or not? Turns out there is a way to do it, albeit a bit geeky.

Amit Agarwal has posted an interesting post where he details determining whether or not an email address exists using a clever trick with telnet. The trick requires you to connect to an email server using telnet and then pinging to see if that email address exists.

If you are interested in knowing more, go ahead and visit the post by Amit at Digital Inspiration. For a quick how-to check out the embedded video below.

Please note that this may not work always as email servers block such queries so that spammers cannot fish legitimate email addresses from their databases.
