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.

New delhi, Jun 22: As consumer sentiment runs high amid growing chorus for boycotting Chinese goods in the country, the fluid market situation offers new opportunities for various smartphone makers, especially the non-Chinese ones like Samsung, Apple, Nokia, Asus and others, to realign their strategies and regain the lost market share in the face of fierce Chinese competition.

The challenge here would be not to look "opportunistic" and leverage the current explosive situation on just riding on the anti-Chinese sentiment but to offer real challenges in the form of top-end devices with solid internals at affordable price points, feel industry experts.

"The current market conditions in India are fluid and open up new opportunities for smartphone original equipment manufacturers (OEMs) to focus and leverage," Prabhu Ram, Head-Industry Intelligence Group, CyberMedia Research (CMR), told IANS.

In the first quarter (January-March) this year, Samsung's shipments were driven by its upgraded A and M series (A51, A20s, A30s, and M30s).

According to Counterpoint Research, Samsung managed to hold third position in Q1 2020 due to launches across several price tiers, especially in the affordable premium segment (S10 Lite, Note 10 Lite).

The South Korean smartphone maker last week announced a Rs 4,000 price drop on its popular Galaxy Note10 Lite smartphone that will now cost Rs 37,999 (6GB variant).

Earlier this month, Samsung launched two new smartphones, Galaxy M11 and Galaxy M01, with powerful batteries under Rs 15,000 in India.

Galaxy M11 comes in two variants. The 3GB+32GB will be priced at Rs 10,999 while the higher 4GB+64GB variant will be available for Rs 12,999.

Samsung has also launched an affordable Galaxy A21s smartphone with quad-camera system and 5,000mAh battery at a starting price of Rs 16,499.

On the other hand, Apple grew a strong 78 per cent YoY driven by strong shipments of iPhone 11 and multiple discounts on platforms like Flipkart and Amazon in Q1, according to Counterpoint.

Apple has also brought its cheapest yet powerful new iPhone SE that costs Rs 38,900 (64GB) in India with a special offer from HDFC Bank. The new iPhone SE is powered by the Apple-designed A13 Bionic, the fastest chip in a smartphone and features the best single-camera system ever in an iPhone.

According to Tarun Pathak, Associate Director, Counterpoint Research, consumer sentiments are running high and a section of users will look for alternatives, benefitting global and Indian brands.

"However, we do not think non-Chinese brands will run aggressive campaigns based on the situation as it might look like being opportunistic," Pathak told media.

It may actually let brands of Chinese origin try to run aggressive campaigns on their presence and scale.

"Some of these Chinese brands have been active in scaling up local value addition, creating jobs and investing in research and development," Pathak noted.

On Saturday, market leader Xiaomi said that it is "more Indian" than any other smartphone brand.

The company's India head Manu Kumar Jain said that the company's mobile phone R&D centre and product team is in India, it employs 50,000 people in the country, the entire leadership team is Indian and that the company pays its taxes in India.

Earlier, Realme India CEO Madhav Sheth who is also very active on social media said that Realme is an Indian startup.

In his latest episode of Ask Madhav' series on YouTube, Sheth said: "I can proudly say Realme is an Indian startup, which is now a global MNC (multinational corporation)".

Melbourne, Jul 24: Home-made cloth face masks may need a minimum of two layers, and preferably three, to prevent the dispersal of viral droplets associated with Covid-19, according to a study.

Researchers, including those from the University of New South Wales in Australia, noted that viral droplets are generated by those infected with the novel coronavirus when they cough, sneeze, or speak.

As face masks have been proven to protect healthy people from inhaling infectious droplets as well as reducing the spread from those who are already infected, several types of material have been suggested for these, but based on little or no evidence of how well they work, the scientists said.

In the current study, published in the journal Thorax, the researchers compared the effectiveness of single and double-layer cloth face coverings with a surgical face mask (Bao Thach) at reducing droplet spread.

They said the single layer covering was made from a folded piece of cotton T shirt and hair ties, and the double layer covering was made using the sew method described by the US Centers for Disease Control and Prevention (CDC).

The scientists used a tailored LED lighting system and a high-speed camera to film the dispersal of airborne droplets produced by a healthy person with no respiratory infection, during speaking, coughing, and sneezing while wearing each type of mask.

Their analysis showed that the surgical face mask was the most effective at reducing airborne droplet dispersal, although even a single layer cloth face covering reduced the droplet spread from speaking.

But the study noted that a double layer covering was better than a single layer in reducing the droplet spread from coughing and sneezing.

According to the researchers, the effectiveness of cloth face masks is dependent on the number of layers of the covering, the type of material used, design, fit as well as the frequency of washing.

Based on their observations, they said a home made cloth mask with at least two layers is preferable to a single layer mask.

"Guidelines on home-made cloth masks should stipulate multiple layers," the scientists said, adding that there is a need for more research to inform safer cloth mask design.
