        Adding letters from name as avatar in buddypress site 

        letters-from-name-as-avatar-in-buddypressHi everyone in my previous post i wrote bout how to show letters from the users name as thier avatars in your wordpress sites the method was feasible for bbpress sites as well but not for buddypress sites so this is the carry over post describing how you can  add letters from name as avatar in your buddypress site as well.

        Plugin to install BuddyPress First Letter Avatar

        BuddyPress First Letter Avatar is based on other plugin  WP First Letter Avatar. BuddyPress First Letter avatar is basically the same thing, but programmed to work with BuddyPress

        BuddyPress First Letter Avatar sets custom avatars for users without profile picture or Gravatar. The avatar will be a first letter of the users’s name. You can also configure plugin to use any other letter to set custom avatar.

        BuddyPress First Letter Avatar includes a set of beautiful, colorful letter avatars in many sizes. Optimal size will be chosen by the plugin in order to display high quality avatar and not download, for example, big 512px avatars when only 48px is needed… PSD template for avatar is also included.

         

        By default, custom avatar will be set only to users without profile pictures and Gravatars, but you can change that in settings and not use Gravatar/profile pictures at all.

        BuddyPress First Letter Avatar helps you bring more colors into your BuddyPress site. Plus, your users will be more willing to actively participate in your site since they can actually relate to these avatars much better than to Mystery Man.

        Few questions and their answers:

        Can I change custom avatars?

        You can create your own avatar set by creating new directory next to ‘default’ folder and following the naming convention from ‘default’.
        Absolutely! Just create new directory in ‘images’ directory, call it, for example ‘my_avatar_set’ and change the avatar set in settings. Make sure to follow the directory and filename convention.
        NOTE: Your custom avatars WILL BE DELETED after updating the plugin! Make backup!

        Can I set custom avatars based on last (or any other) character in user’s name?

        Of course! This can be done in plugin settings.

        I don’t want to use Gravatar at all. Can I disable it?

        Yes! By default, BuddyPress First Letter Avatar sets custom avatar only to users without Gravatar and profile avatar, but in plugin settings you can disable it and use custom avatar for everybody.

        Can avatars be round, like in Google+?

        Yes – just go to plugin settings and click Round avatars.

        Will users still be able to use their own avatars?

        Absolutely. The default priority is: first look for user’s profile avatar, then try to get Gravatar. If these options fail, use BuddyPress First Letter Avatar and assign custom first letter avatar. You can disable using users’ profile avatars and/or Gravatars in BuddyPress First Letter Avatar settings.

          Adding letters from name as avatar in wordpress site 

          Hi this is a small post showing how you can easily add custom avatars displaying the first alphabet from the name of your site members as there avatar if they don’t already have one,that means

          if (they have uploaded some picture as there avatar)
          {
          it will show that picture
          else
          it will display the first letter from there name as there avatar
          }

          You can also configure plugin to use any other letter to set custom avatar.
          letters-from-name-as-avatar-in-wordpressWP First Letter Avatar includes a set of beautiful, colorful letter avatars in many sizes. Optimal size will be chosen by the plugin in order to display high quality avatar and not download, for example, big 512px avatars when only 48px is needed… PSD template for avatar is also included.

          Trust me it looks cooler and more logical then that mystery man which appears other wise.
          So here is the procedure:

          1. Install the plugin named as WP First Letter Avatar , learn how to install a wordpress plugin.
          2. Goto Dashboard >>settings>>WP First Letter Avatar
          3. Adjust settings as per your need and click on save button.
          4. Clear your browser and site cache now visit your site to notice the changes.
          5. The First letter avatars will only show up for people who don’t already have an avatar.

          WP First Letter Avatar helps you bring more colors into your blog. Plus, your readers will be more willing to comment on your posts, since they can actually relate to these avatars much better than to Monsters or Mystery Man.

          Settings Fields description:

          Letter index
          0: To use first letter for the avatar
          1: To use second letter
          -1: To use last letter, etc.

          File format
          File format of your avatars, for example png or jpg,if you want quality use ong if speed then jpg.

          Unknown image name
          Name of the file used for unknown usernames (without extension).

          Avatar set
          Directory where your avatars are stored.

          Use Gravatar
          Check: use Gravatar when available
          Uncheck: always use custom avatars.

          Round avatars
          Check: If you want to use rounded avatars
          Uncheck:use standard avatars.

          Note that the plugin is fully compatible with wordpress and as well as bbpress.

          All images were compressed using the fantastic TinyPNG, so avatars are incredibly light and ultra-high quality.

          You can also create your own avatar set by creating new directory next to ‘default’ folder and following the naming convention from ‘default’. Keep in mind that your avatar set will be deleted after updating plugin!

          By default, custom avatar will be set only to users without Gravatars, but you can change that in settings and not use Gravatar at all.

            MITM : Man In The Middle Attack Explained 

             MITM-BRAINLUBRICATOR-MAN-IN-THE-MIDDLE-ATTACK.Note:Before reading the post please see and read the info in the above picture once so that you get better understanding of what is explained below,the example used is just a test case.
            So recently a new vulnerability FREAK was discovered which allows hackers to launch man in the middle attack even on the connections which uses ssl/tsl for encryption.
            This is a supplementary post to explain what Mitm or man in the middle attack is.
            So here is one of the test scenario explaining the flow of the attack:
            Some legit user like you or me is browsing the web and found a very good gadget or goodies which we cant refuse to buy from some online store due to a very good and limited time offer.
            So we select the color, no of items we want to buy and other attributes etc and add them to our cart cool after doing all this we are headed to the payment page,now this is the moment the attacker is waiting for.
            Let us assume that the total cost of all the items that we added to our cart comes out to be 1000 rupees so we enter the price to be paid as 1000 rupees and then add our account or card details and hit the Make payment or submit button thinking that the details are being sent to the online store(bank payment gateway system) well that is what happens in normal case but if you have been affected by Mitm attack the information is actually first received by some hacker before it is received by the original website who edits it as per his/her needs changing the meaning or information passed completely and then forward it to the server or the original website,now to stay hidden for longer time the hacker may also edit the message which is received in response to the payment request
            for example if the payment of 1000 rs was made the server would respond as thank you we just received the payment of 1000rs but as the hacker may have edited the amount to 5000Rs the response message which will be received will be thank you payment of 5000 rs has been received which is again manipulated by the hacker to say 1000Rs instead of 5000 rs so that user only comes to know about the actual price once he/she receive his/her bank statement.

            So in short MITM or man in the middle attack is sniffing some information or message from original source before it reaches the intended receiver>>editing it for some own malicious or illegal purpose or to completely change the meaning>>forwarding it to the destination or intended receiver.
            Bob(Sender)->Hi friends class test at 2 pm.
            Hacker(Man in middle)->Hi friends class test at 5 pm.
            Alice(Receiver)->Missed her test as the message she received was test at 5 pm although the test was planned for 2 pm.
