Flashing yellow lights

By
So, earlier today i was going to a place for some work with my grandmother when i saw these peculiar traffic signals which had blinking lights. 

All of us had might noticed this but i am sure that we never decided to understand the purpose. I did quite a research and found out that they did not mean that the lights weren't working but they do serve a purpose. I have never seen flashing red lights but apparently they too exist. 
  •  A flashing red light means come to a complete stop, then proceed when you can.
  • A flashing yellow light means proceed with caution.
This is not a regular daily post but just something i wanted to share with all my readers for the welfare of the society.

Football crazy  Dev malhotra woke up once again on a fine and sunny Sunday ready for a football match which he has been waiting and practicing for more than a month now..........................the match was scheduled on 7:00p.m (sharp) at the close by deserted ground.He called his father again to practice for the last time before the match starts,  at the ground as he wanted to play like never before.Motivation for the entire effort  was an awesome phone his Dad would gift ,if they won.He was eagerly waiting for the phone e was wanting from long back.When he was small,he used to get denied of a cellular phone because his parents used to always advice him that "too much exposure to technology will get your concentration out of studies".He also called up his best friend,John for the football practice. They all started in dev's car to the ground.After reaching,they immediately started doing goal practice.john was an expert in goal keeping and dev's dad in his

The Flash- Run Iris, Run Review

By
What's new about this Flash episode? The Flash isn't the Flash for a major part of the episode. Barry allen loses his speed because of a Meta-Human who unwillingly touches Iris and Barry at the same time interchanging their molecular DNA connected to the SpeedForce. So, the episode was pretty. Agreed, it was hyped more than it needed because half the time Iris was lying down screaming for help. But it was fun seeing Barry sit down and relax for a change. This episode had a major change in Cisco's attitude towards Harry and it was nice to see them work together. Though, they can give Killer Frost / Caitlyn more screentime. This episode was a nice addition the already ongoing war between DeVoe and Team Flash. But not worthy enough for the 3 week break . Anyways, enjoy the break. Which is after the Winter Olympics break. Which was after the 2 week long break. P. S. Dont break your head.

Now, according to the Merriam-Webster dictionary, security is defined as: "    measures taken to guard against espionage or sabotage, crime, attack, or escape "  In this case, we are dealing with highly professional hackers who are powerful and knowledgeable enough to hack into the US power grid.  so, what do we do?  We are going to learn how and why they do it.  An average day on wordpress sees around 500,000 views new posts .

To get useful data from you  3.For fun, because who would not want to ruin competition?  4.To eliminate you, as in k
