While Sharing the url via social fb , twitter , linkedin etc , sometime we face the issue of old version of image/content. This mostly happens with LinkedIn ;) If you share an older post or page it will grab the Open Graph tags to display the image and meta information. The problem is LinkedIn probably has your old tags cached on its system. So you need a way to refresh it. To fix this you simply need to add a query string to the end of the URL. For example, I changed the following: https://svikramjeet.blogspot.in to https://svikramjeet.blogspot.in/?ref=home It doesn’t matter what it is, and in fact the URL above will still work. This will then update the post information as LinkedIn can’t cache query strings. You can in fact then actually remove the query string, leaving your original URL, as LinkedIn will then have the up to date Open Graph tags. You can see below the new information that was now pulled from the same URL. And that’s it! You have now cleared LinkedIn cach...

World Cup 2014 Brazil Group G Match Thomas Müuler’s goal in the 55th minute gave the Germans a 1-0 victory, but that result, coupled with Portugal’s 2-1 win over Ghana, left the Americans in second place in Group G, the so-called Group of Death . That is good enough for Team USA to qualify for the round of 16, where they will probably meet Belgium. “It’s huge for us, getting out of this group,” Coach Jurgen Klinsmann said. “Everybody said you have no chance. We took that chance, and we move on and now we really want to prove a point.” “Today was a tough game, tough conditions,” goalkeeper Tim Howard said. “Hats off to Germany. I think they have a chance to win the World Cup -- that’s how good I think they are. But we get to the round of 16. It shows how far we’ve come that we’re not happy, that we want to progress.” The heavy-legged Americans rarely tested Germany, who finished with 68 percent ball possession for the match and 7 points as champions of the group. Th...

Always looking for new opportunities to turn its mammoth search engine and associated features into interactive and exceedingly distracting Easter eggs, Google has put on another show in honor of the 37th birthday of Atari's classic video game "Breakout." Just try typing "Atari Breakout" into Google's image search. Instead of getting the usual cluster of high- and low-resolution images of the retro paddle-based game, the screen then transforms all the images into tiny bricks for you to destroy in a game Google is calling "Image Breakout." Occasionally and for whatever reason, Google image search will redirect to another search entirely before activating the game. I got "Parmigiana" and "Chicago" in that order, so I was destroying tiny little bricks made out of Italian Parm sandwiches and Windy City landmarks. Originally created by Nolan Bushnell and Steve Bristow, "Breakout" debuted in 1976. It was based on a simil...
