Not only dating apps, 20 more apps sending sensitive information to Facebook

Twitter has hinted that it is planning a paid subscription platform that can be reused by other teams in the future.

The news that the micro-blogging platform is building a subscription platform with a team codenamed "Gryphon" resulted in Twitter stock rising over 8% on Wednesday.

Twitter revealed its plan via a job listing that seeks a full-stack senior software engineer in New York to join "Gryphon".

Interestingly, Twitter "edited" the job listing once the news broke, removing the part about "Gryphon" and any mention of their internal team or their subscription feature. The listing said the company is looking for an Android engineer to "work on a bevy of backend engineering teams to build components that allow for experimentation to deliver the best experience possible to all of our users".

Later, Twitter users noticed that the company restored the earlier job listing that mentioned the upcoming subscription platform and "Gryphon".

A spokesperson for Twitter told CNN on Wednesday that it's only a job posting, not a product announcement.

This is not the first time Twitter has thought of a paid product. 

In 2017, it sent out a survey to users and a preview of what a premium offering of its TweetDeck app might look like, including breaking news alerts and more analytics, according to The Verge.

"We're conducting this survey to assess the interest in a new, more enhanced version of Tweetdeck. We regularly conduct user research to gather feedback about people's Twitter experience and to better inform our product investment decisions, and we're exploring several ways to make TweetDeck even more valuable for professionals," a Twitter spokesperson had said at that time.

Denser places, assumed by many to be more conducive to the spread of the coronavirus that causes COVID-19, are not linked to higher infection rates, say researchers.

The study, led by Johns Hopkins University, published in the Journal of the American Planning Association, also found that dense areas were associated with lower COVID-19 death rates.

"These findings suggest that urban planners should continue to practice and advocate for compact places rather than sprawling ones, due to the myriad well-established benefits of the former, including health benefits," says study lead author Shima Hamidi from Johns Hopkins Bloomberg School of Public Health in the US.

For their analysis, the researchers examined SARS-CoV-2 infection rates and COVID-19 death rates in 913 metropolitan counties in the US.

When other factors such as race and education were taken into account, the authors found that county density was not significantly associated with county infection rate.

The findings also showed that denser counties, as compared to more sprawling ones, tended to have lower death rates--possibly because they enjoyed a higher level of development including better health care systems.

On the other hand, the research found that higher coronavirus infection and COVID-19 mortality rates in counties are more related to the larger context of metropolitan size in which counties are located.

Large metropolitan areas with a higher number of counties tightly linked together through economic, social, and commuting relationships are the most vulnerable to the pandemic outbreaks.

According to the researchers, recent polls suggest that many US citizens now consider an exodus from big cities likely, possibly due to the belief that more density equals more infection risk.

Some government officials have posited that urban density is linked to the transmissibility of the virus.

"The fact that density is unrelated to confirmed virus infection rates and inversely related to confirmed COVID-19 death rates is important, unexpected, and profound," said Hamidi.

"It counters a narrative that, absent data and analysis, would challenge the foundation of modern cities and could lead to a population shift from urban centres to suburban and exurban areas," Hamidi added.

The analysis found that after controlling for factors such as metropolitan size, education, race, and age, doubling the activity density was associated with an 11.3 per cent lower death rate.

The authors said that this is possibly due to faster and more widespread adoption of social distancing practices and better quality of health care in areas of denser population.

The researchers concluded that a higher county population, a higher proportion of people age 60 and up, a lower proportion of college-educated people, and a higher proportion of African Americans were all associated with a greater infection rate and mortality rate.

New Delhi, Jan 25: The Patiala House court on Saturday started hearing a plea filed by the Nirbhaya convicts that alleged that the Tihar Jail administration have "not presented the papers on time".

The Public Prosecutor informed the court that Tihar Jail authorities have already supplied the relevant documents. He further informed that these are mere delaying tactics adopted by the convicts.

Advocate A.P. Singh, lawyer for three of the four death row convicts in the Nirbhaya gang-rape case had moved an application before the court seeking directions to the Tihar Jail authorities to supply him the relevant documents in order to exercise the remaining legal remedies available with the death row convicts -- Vinay Pawan and Akshay.

The Public Prosecutor also told the court that he spoke to the jail authorities over the phone and a report in this regard will be filed shortly as the jail officials were on their way to the court.

The judge demanded from the convicts lawyer to show what he has filed.

The convicts lawyer, A.P. Singh, said that he received some documents, but has still not been supplied with the personal diary of one of the convict -- Vinay Kumar Sharma and also the medical documents.

Judge then asked the lawyer to wait for until the report arrives form the Tihar Jail.

On this, the convicts lawyer said he was not questioning the intention of the jail. "I know the jail has been changed. It isn't there fault, too," he said.

The Public Prosecutor refuted the allegation saying that the defence counsel was trying to defeat the speed of law.

"We have supplied all the documents to the counsel. We have supplied all the documents except the painting and some other documents. We have nothing apart from that," public prosecutor said.

Singh, in his plea filed before the Patiala House Court sought urgent orders of the court in order to file a mercy petition of Vinay Sharma and in relation to requests for documents for convicts Vinay Sharma, Pawan Kumar Gupta and Akshay Kumar Singh.

He further said that the convicts undertook several steps to obtain relevant information necessary for filing the mercy petitions. In regular interval, the convicts requested the concerned authority to supply documents pertaining to their medical records from 2012 to 2015 and 2019-2020, records of cellular confinement, records of the amount earned in prison through labour, records of educational and reformative activities like Tihar Olympics and Painting, etc.

The Supreme court had recently dismissed the curative petition for the other two convicts -- Vinay Kumar Sharma (26) and Mukesh Singh (32).

The court had recently issued death warrant against the convicts and fixed 6 a.m. on February 1 as the date and time of execution of the death penalty.

The 23-year-old victim in the case was brutally gang raped and tortured on December 16, 2012, which later led to her death. All the six accused were arrested and charged with sexual assault and murder. One of the accused was a minor and appeared before a juvenile justice court, while another accused committed suicide in Tihar Jail.

Four of the convicts were sentenced to death by a trial court in September 2013, and the verdict was confirmed by the Delhi High Court in March 2014 and subsequently upheld by the Supreme Court in May 2017, which also dismissed their review petitions.

A Juvenile involved in the crime was convicted by a juvenile justice board and released from a reformation home after serving a three-year term.

Hearing in a different case, Chief Justice of India S.A. Bobde on Thursday said a condemned person cannot fight the death penalty endlessly and it was important for the capital punishment to reach its finality.

The death penalty, he noted, cannot be questioned at every turn by the convict.
