I have struggled to find out on how to delete a WhatsApp group that I created mistakenly. Since there are no options available directly in the screen and it showed like below. So I did the below steps to delete it. 1. Remove all the participants from the Group. 2. After you remove all the participants, you have to exit yourself from the group, by clicking the button "Exit Group". 3. Now you will see the "Delete Group" button appear on the screen. 4. Delete the group happily and start talking to the next person. Save humanity.

This is happened on a school function, where our people's president was the chief guest. During his talk, he insisted the school students to ask any question. One student around 7 years old asked "Which achievement gave you great happiness?" He smiled and answered "I'm shocked to hear a deep question from you. Well, I was happy many times, during the successful satellite launch, during the Agni and Prithivi missile launches, and also i was happy when the nuclear test was successful. But during the missile research, i created a new composite, which is like a fiber, weightless yet very stable and hard to break. When my project director visited our laboratory which is located at Hyderabad, i showed him my creation can be used in our future missiles. He said, you are going to use this on a thing that causes tragedy (missile), also why don't remove the tragedy through this. I was confused. Then he took me to the orthopedics hospital near our place. I saw ...

HA-PROXY SETUP FOR OPENSTACK SERVICES INTRODUCTION: To obtain maximum uptime in openstack services we are in need of high availability (aka HA ) in this document we are using ha-proxy for openstack HA and keepalived for H a-proxy HA. Software topology As mentioned, we’ll use the following set of software: the services themselves; HAProxy for making the services HA; and Keepalived for making HAProxy HA. Getting hands-on Suppose we have two machines, from which we want to make an HA OpenStack controller pair, installing both the API services and Keepalived + HAProxy. Suppose machine 1 has address 192.168.56.200, machine 2 has address 192.168.56.201, and we want the services to be accessible through virtual IP 192.168.56.210. And suppose all these IPs are on eth1. Installing necessary packages $ sudo apt-get install haproxy keepalived Configuration of haproxy This configuration is identical on both nodes and resides in /et...

Introduction We used five machines for swift setup . In that, 3 machines will act as swift-proxy servers and all 5 machines will act as swift-storage nodes. Swift with HA proxy setup We have installed HA proxy service in all three proxy servers. The KeepAlived service will monitor the HA proxy health and assign the floating virtual IP address(192.168.1.xxx) to the high priority HA proxy server. (102 is master, 101 is slave1, 100 is slave2) The HA Proxy will check all three proxy servers and send the request in round robin method. If one proxy server fails, it will automatically sends the request to the other two proxy servers only, until the failed proxy server is back online. Swift Proxy Node setup We have configured three swift proxy nodes in the public network(192.168.1.xxx) and it is connected to all the storage nodes through a private network(172.0.0.xxx). Rings The ring builder has created an account ring, container ring and ob...
