ISRO launches GSLV Mark III with GSAT-19 communication satellite

Twitter has joined efforts to do away with racially loaded terms such as master, slave and blacklist from its coding language in the wake of the death of African-American George Floyd and ensuing Black Lives Matter protests.

The project started even before the current movement for racial justice escalated following the death of 46-year-old George Floyd in police custody in May.

The use of terms such as "master" and "slave" in programming language originated decades ago. While "master" is used to refer to the primary version of a code, "slave" refers to the replicas. Similarly, the term "Blacklist" is used to refer to items which are meant to be automatically denied.

The efforts to change these terms in favour of more inclusive language at Twitter were initiated by Regynald Augustin and Kevin Oliver and the microblogging platform is now backing their efforts.

"Inclusive language plays a critical role in fostering an environment where everyone belongs. At Twitter, the language we have been using in our code does not reflect our values as a company or represent the people we serve. We want to change that. #WordsMatter," Twitter's engineering team said in a post on Thursday.

As per the recommendations from the team, the term "whitelist" could be replaced by "allowlist" and "blacklist" by "denylist".

Similarly, "master/slave" could be replaced by "leader/follower", "primary/replica" or "primary/standby".

Twitter, however, is not the first to start a project to bring inclusivity in programming language.

According to a report in CNET, the team behind the Drupal online publishing software started using "primary/replica" in place of "master/slave" as early as in 2014.

The use of the terms "master/slave" was also dropped by developers of the Python programming language in 2018.

Now similar efforts are underway at Microsoft's Github and LinkedIn divisions as well, said the report.

Amid the rapid spread of the novel coronavirus (COVID-19), which has infected 73 people in India and killed more than 4,500 individuals globally, doctors have advised that in addition to regularly washing hands, one should also disinfect their smartphone every 90 minutes with alcohol-based hand sanitizer.

Ravi Shekhar Jha, Head of Department at Fortis Escorts Hospital in Faridabad said the best method to disinfect your smartphone is to use regular doctor spirit or the alcohol-based hand sanitizer at least every 90 minutes.

"Avoid touching your eyes, mouth, or nose. The best option is to use a phone cover or a Bluetooth device and try to touch your phone as less as possible. We would also recommend cleaning your phone at least twice a day," Jha told IANS.

According to research, published in 2018 by Insurance2Go, a gadget insurance provider, revealed that smartphone screens have three times more germs than a toilet seat.

One in 20 smartphone users was found to clean their phones less than every six months, said the study.

"In the time of fear of coronavirus, smartphones should also be disinfected with alcohol-based sanitizer rub. Pour few drops of sanitizer on a tiny clean cotton pad and rub it safely on your entire phone," said Jyoti Mutta, Senior Consultant, Microbiology, Sri Balaji Action Medical Institute in New Delhi.

"You can repeat this process every evening coming back home after an entire day out at work and once in the morning before going out," Mutta added.

"Maintain basic cleanliness, and try to avoid using other's phones especially if suffering from respiratory illness or flu-like symptoms as there is no other way to disinfect these regular gadgets," she stressed.

Another study from the University of Surrey in the UK, also found that the home button on your smartphone may be harbouring millions of bacteria - some even harmful.

The World Health Organisation (WHO) declared the novel coronavirus as a global pandemic on Wednesday. The death toll of COVID-19 has crossed the 4,500 marks and confirmed cases globally have touched one lakh as per the reports.

According to Suranjeet Chatterjee, Senior Consultant in Internal Medicine Department of Indraprastha Apollo Hospitals in New Delhi, "We should frequently wash our hands, cover our coughs and it is important to adapt to other good hygiene habits that are most important in such a situation."

"Coronavirus and other germs can live on surfaces like glass, metal or plastics and phones are bacteria-ridden. It is necessary that we sanitize our hands frequently and make sure that our hands are clean all the time," Chatterjee told IANS.

"The emphasis should be laid on sanitising our hands rather than sanitizing the phone - once in a while the phone can be sanitized under the guidance of the makers of the phone," Chatterjee stressed.

According to the global health agency, the most effective way to protect yourself against coronavirus is by frequently cleaning of your hands with alcohol-based hand rub or washing them with soap and water.

The WHO's report showed the virus infects people of all ages, among which older people and those with underlying medical conditions are at a higher risk of getting infected.

People should eat only well-cooked food, avoid spitting in public, and avoid close contact, the WHO said, adding that it is important for people to seek medical care at the earliest if they become sick.

Cape Canaveral, May 31: SpaceX, the private rocket company of billionaire entrepreneur Elon Musk, launched two Americans into orbit from Florida on Saturday in a landmark mission marking the first spaceflight of NASA astronauts from U.S. soil in nine years.

A SpaceX Falcon 9 rocket lifted off from the Kennedy Space Center at 3:22 p.m. EDT (19:22 GMT), launching Doug Hurley and Bob Behnken on a 19-hour ride aboard the company’s newly designed Crew Dragon capsule bound for the International Space Station.

Just before liftoff, Hurley said, “SpaceX, we’re go for launch. Let’s light this candle,” paraphrasing the famous comment uttered on the launch pad in 1961 by Alan Shepard, the first American flown into space.

Minutes after launch, the first-stage booster rocket of the Falcon 9 separated from the upper second-stage rocket and flew itself back to Earth to descend safely onto a landing platform floating in the Atlantic.

High above the Earth, the Crew Dragon jettisoned moments later from the second-stage rocket, sending the capsule on its way to the space station.

The exhilarating spectacle of the rocket soaring flawlessly into the heavens came as a welcome triumph for a nation gripped by racially-charged civil unrest as well as ongoing fear and economic upheaval from the coronavirus pandemic.

The Falcon 9 took off from the same launch pad used by NASA’s final space shuttle flight, piloted by Hurley, in 2011. Since then, NASA astronauts have had to hitch rides into orbit aboard Russia’s Soyuz spacecraft.

“It’s incredible, the power, the technology,” said U.S. President Donald Trump, who was at Kennedy Space Center at Cape Canaveral in Florida for the launch. “That was a beautiful sight to see.”

The mission’s first launch attempt on Wednesday was called off with less than 17 minutes remaining on the countdown clock. Weather again threatened Saturday’s launch, but cleared in time to proceed with the mission.

SPACEFLIGHT MILESTONES

NASA chief Jim Bridenstine has said resuming launches of American astronauts on American-made rockets from U.S. soil is the space agency’s top priority.

“I’m breathing a sigh of relief, but I will also tell you I’m not gonna celebrate until Bob and Doug are home safely.” Bridenstine said.

For Musk, the launch represents another milestone for the reusable rockets his company pioneered to make spaceflight less costly and more frequent. And it marks the first time commercially developed space vehicles - owned and operated by a private entity rather than NASA - have carried Americans into orbit.

The last time NASA launched astronauts into space aboard a brand new vehicle was 40 years ago at the start of the space shuttle program.

Musk, the South African-born high-tech entrepreneur who made his fortune in Silicon Valley, is also chief executive of electric carmaker and battery manufacturer Tesla Inc. He founded Hawthorne, California-based SpaceX, formally known as Space Exploration Technologies, in 2002.

Hurley, 53, and Behnken, 49, NASA employees under contract to fly with SpaceX, are expected to remain at the space station for several weeks, assisting a short-handed crew aboard the orbital laboratory.

Boeing Co, producing its own launch system in competition with SpaceX, is expected to fly its CST-100 Starliner vehicle with astronauts aboard for the first time next year. NASA has awarded nearly $8 billion combined to SpaceX and Boeing for development of their rival rockets.

Trump also hailed the launch as a major advance toward the goal of eventually sending humans to Mars.

He was joined at the viewing by Musk, as well as Vice President Mike Pence, Commerce Secretary Wilbur Ross, Education Secretary Betsy DeVos, Florida congressman Matt Gaetz and Senator Rick Scott.

Earlier on Saturday, the crew bid goodbye to their families. Prior to climbing into a specially designed Tesla automobile for the ride to the launch site, Behnken told his young son, “Be good for mom. Make her life easy.”

During the drive, Behnken and Hurley passed former astronaut Garrett Reisman who held a sign saying, “Take me with you.”
