The creators of the Kotlin programming language — the Czech software development company Jetbrains — announced results from their annual "State of the Developer Ecosystem" survey. This year's survey involved 19,696 developers in 18 countries, and found that:

• JavaScript is the most used overall programming language. Websites are the most common type of application developers work on.

• Python has overtaken Java in the list of programming languages used in the last 12 months. And it is also the most studied language. In the last 12 months 30% of respondents have started or continued to learn Python — even more than last year.

• Go, Kotlin, and Python are the top 3 languages developers are planning to adopt or migrate to.

JetBrains also gathered some statistics from programmers for a special section on Lifestyle and Fun:

• 65% said they preferred laptops, while 33% preferred desktops.
• 52% said they contributed to charity.
• 20% said they owned a cat; another 20% said they owned a dog.
• 16% said they owned cryptocurrency.

And when asked if they contributed to open-source projects:

• 44% said "No, but I would like to."
• 20% said "I have only contributed a few times."
• 16% said "Yes, from time to time (several times a year)."
• 11% said "Yes, regularly (at least once a month)."
• 4% said "No, and I would not like to."
• 3% said "I work full-time on open-source code and get paid for it."
• 2% said "I work full-time on open-source code but do not get paid for it."

Also interesting were the answers to the question: If your country's government replaced your courts with AI, would you trust it? The results were:

• Probably not (26%)
• Definitely not (24%)
• Maybe (26%)
• Probably yes (20%)
• Definitely yes (5%)

"An innocent man faced a torrent of online threats and abuse after being mistakenly identified in a viral video in which an angry cyclist hurt a child," reports the BBC: Mr. Weinberg was falsely identified when the wrong date was attached to the initial appeal made by the police in Bethesda, U.S. Mr. Weinberg used the popular fitness tracking app Strava, which showed him as having been on the Maryland bike trail on that day.

However on the correct date he was working at home...

Once his address had been shared by others — a practice known as doxxing — the police had to patrol the area for his safety, reported New York magazine... Mr. Weinberg has since received dozens of apologies from people who abused him online.
Weinberg mistakenly thought his app only shared his bike-ride routes with his network of friends, New York Magazine reports.

They add that Weinberg also discovered tweets wrongly accusing another man — a former police officer in Maryland — which had been retweeted and liked more than half a million times. And that the woman who'd posted Weinberg's home address later "deleted it and posted an apology, writing that in all of her eagerness to see justice served, she was swept up in the mob that so gleefully shared misinformation, depriving someone of their own right to justice.

"Her correction was shared by fewer than a dozen people."

NBC News reports that in various parts of America, "States that had committed to using contact tracing apps or expressed interest are now backing away from those claims." The few states that have rolled them out have seen only tepid responses. And there are no indications of any momentum for the apps at a national level... A survey of state health officials from Business Insider this week showed that only three states — Alabama, North Dakota and South Carolina — said they were going to use the software provided by Apple and Google. The number hasn't grown since the same three states reported interest last month, and none has launched an app with the Google-Apple software...

Even the World Health Organization has piled on. "Digital tools do not replace the human capacity needed to do contact tracing," WHO Director-General Tedros Adhanom Ghebreyesus said at a briefing this week, adding that more evidence was needed and that the WHO would convene experts to share information...

A handful of states — North Dakota, South Dakota and Utah — launched apps without the support of Apple and Google, but none saw widespread adoption. More states, including Washington, have considered doing so or have launched test versions, and it's possible that apps will gain momentum closer to the fall, when they might be taken up by more employers, schools and universities and at related football games.
Two months ago Google and Apple announced a joint project to build a contact-tracing app -- which was supported by the governor of America's most populous state, California. But now a spokesperson for California's public health department tells NBC News that the state isn't currently using any apps or cellphone tracking technology.

"Most of the contact tracing work (notifying people who have been in close contact with an infected person to prevent the disease from spreading to others) can be done by phone, text, email and chat."
