About Twitter Profile Labels

Twitter uses visual identity signals like labels and badges on account profiles to help distinguish between various account types and to give more context about them. While some of these labels are generated by Twitter, others are the result of user activity. Here is a list of the labels and badges that are frequently seen on account profiles. Applied Profile labels by Twitter Checkmark in Blue The blue checkmark can indicate one of two things: either that a user's account has been verified according to Twitter's previous verification standards (active, notable, and authentic), or that the user has an active subscription to Twitter Blue, the company's new subscription service that launched on iOS on November 9, 2022. The active, notable, and authentic criteria that were applied in the previous process will not be reviewed for accounts that receive the blue checkmark as part of a Twitter Blue subscription.

Electric planes are now flying!

More airlines are purchasing battery-powered aeroplanes to lessen their impact on the environment.

Even if flying is handy, it's not great for the environment; according to some estimates, just commercial flights alone are to blame for 3 to 4% of all greenhouse gas emissions in the US.


However, one approach to lessen the sector's climate impact is by electrifying air travel. Battery-powered aircraft are also beginning to acquire more traction, despite the fact that experts believe substantial commercial use is still in the future.

By acquiring 30 battery-powered passenger planes from Heart Aerospace, a Swedish company, this week, Air Canada became the most recent airline to make the commitment to test the cutting-edge, zero-emission technology. In the summer of 2016, 100 of the company's aircraft were ordered by United Airlines and regional carrier Mesa Airlines, respectively.

These still-in-development electric aircraft are currently modest, holding no more than 30 passengers. The plane built by Heart Aerospace, which is propelled by more than 5 tonnes of lithium-ion batteries, can only travel 124 miles on a single charge. However, Pranshu Verma of the Washington Post reports that it may increase its range to nearly 500 miles with the aid of a fuel-powered generator. Even so, the so-called "hybrid mode" would still generate 50% fewer emissions than regular aircraft. The executives of Heart Aerospace claim that this electric aircraft would also be substantially quieter.

The Swedish business claims that its aircraft might be ready as early as 2028, but before they can fly, a number of regulatory obstacles must be overcome.

The environmental effects of airlines and the travel sector as a whole have drawn criticism. They're responding by setting high goals and objectives. By utilising a combination of cleaner fuel and carbon offsets, United, for instance, has promised to reduce emissions by 100% by the year 2050, while nations like Sweden and Denmark have set objectives to eliminate using fossil fuels for domestic flights by the end of this decade. Additionally, cruise lines have committed to address climate change, with organisations like Hurtigruten Norway promising to introduce the first passenger ship with zero emissions by 2030. The German state of Lower Saxony recently introduced its first fleet of passenger trains that are totally powered by hydrogen. Trains are also becoming greener.

Cinderella Was Not Invented by Disney!

Century-long narratives from numerous cultures are woven together to create the real Cinderella.   You're familiar with Cinderella. You do, of course. She is a character we learn about through osmosis because she is a part of the cultural ether. Princess that she is. She is decked out in a lovely dress, glass shoes, long white gloves, and a shiny headband. To meet and dance with a very handsome prince and get home before the clock strikes midnight and her carriage turns back into a pumpkin, she overcomes the hardship of her evil stepmother and stepsisters, who treat her like their maid.  However, that isn't the true Cinderella. That is the Cinderella from the 1950 animated film and the recent remake that is currently playing in theatres. Not everyone can agree on who the real Cinderella is. She is a figure who connects the majority of human cultures and centuries of storytelling. And occasionally, her lost slipper isn't even made of glass. Greeks were the first Cinderellas....

How Google was born?

At Stanford University in 1995, the Google story first begins. Sergey Brin, a current student at Stanford, was chosen to give Larry Page a tour while he was considering the university for graduate study. According to some accounts, they didn't agree on much during that initial meeting, but by the following year they had formed a partnership. They developed a search engine from their dorm rooms that used links to gauge the significance of particular Web pages. This search engine was given the name Backrub. Backrub was renamed Google shortly after that (phew). The name, which was a pun on the mathematical formula for 1 followed by 100 zeros, perfectly encapsulated Larry and Sergey's goal of "organising the world's information and making it broadly accessible and useful."  Over the following few years, Google attracted the interest of Silicon Valley investors in addition to the academic community. Google Inc. was founded when Andy Bechtolsheim, a co-founder of Sun, g...
