An anonymous reader quotes a report from TechCrunch: Twitter retains direct messages for years, including messages you and others have deleted, but also data sent to and from accounts that have been deactivated and suspended, according to security researcher Karan Saini. Saini found years-old messages in a file from an archive of his data obtained through the website from accounts that were no longer on Twitter. He also reported a similar bug, found a year earlier but not disclosed until now, that allowed him to use a since-deprecated API to retrieve direct messages even after a message was deleted from both the sender and the recipient -- though, the bug wasn't able to retrieve messages from suspended accounts.

A huge study at Indiana University, led by Elizabeth Canning, finds that the attitudes of instructors affect the grades their students earned in classes. The researchers conducted their study by sending out a simple survey to all the instructors of STEM courses at Indiana University, asking whether professors felt that a student's intelligence is fixed and unchanging or whether they thought it could be developed. Then, the researchers were given access to two years' worth of students' grades in those instructors' classes, covering a total of 15,000 students. Ars Technica reports: The results showed a surprising difference between the professors who agreed that intelligence is fixed and those who disagreed (referred to as "fixed mindset" and "growth mindset" professors). In classes taught by fixed mindset instructors, Latino, African-American, and Native American students averaged grades 0.19 grade points (out of four) lower than white and Asian-American students. But in classes taught by "growth mindset" instructors, the gap dropped to just 0.10 grade points. No other factor the researchers analyzed showed a statistically significant difference among classes -- not the instructors' experience, tenure status, gender, specific department, or even ethnicity. Yet their belief about whether a students' intelligence is fixed seems to have had a sizable effect.

An anonymous reader quotes a report from Gamasutra: In the wake of Activision Blizzard's massive layoff wave, a move that was announced in the same call as the company's record quarter, the union federation AFL-CIO has published an open letter to game developers urging members of the industry to organize. The AFL-CIO itself is the largest labor organization in the United States and counts 55 individual unions (and more than 12.5 million workers) among its affiliates. The letter, readable in full on Kotaku, calls out many of the issues that have prompted conversations about unionization in just recent years like excessive crunch, toxic work conditions, inadequate pay, and job instability. The industry, points out AFL-CIO's secretary-treasurer Liz Shuler, boasted sales 3.6 times greater than those of the film industry in 2018, yet much of that financial success isn't felt by the developers working on the games that generate those billions. "Executives are always quick to brag about your work. It's the talk of every industry corner office and boardroom. They pay tribute to the games that capture our imaginations and seem to defy economic gravity. They talk up the latest innovations in virtual reality and celebrate record-smashing releases, as your creations reach unparalleled new heights," says Shuler.
"My question is this: what have you gotten in return? They get rich. They get notoriety. They get to be crowned visionaries and regarded as pioneers. What do you get? Outrageous hours and inadequate paychecks. Stressful, toxic work conditions that push you to your physical and mental limits. The fear that asking for better means risking your dream job. [...] Change will happen when you gain leverage by joining together in a strong union. And, it will happen when you use your collective voice to bargain for a fair share of the wealth you create every day. No matter where you work, bosses will only offer fair treatment when you stand together and demand it."Read Replies (0)

From a report: A new robot can navigate without GPS, using the same light-sensing abilities as desert ants. Desert ants survive in searingly hot conditions in the Sahara. They sometimes have just a few minutes to forage for food before they risk burning to death. As a result, they are very efficient navigators, using bands of polarized light, invisible to humans, to get around. They also carefully count their steps. These two tactics help to keep them alive. AntBot: The bot, described this week in Science Robotics, is fitted with UV light sensors that can detect polarized light from the sun. This is known as a "celestial compass" and is designed to mimic the way desert ants see the sun's light. This helps it work out the direction it's going in. The robot also counts its steps, much like its desert muse. In tests, it successfully managed to complete an outdoor homing task, where it was required to go to several checkpoints and then return to a fixed location within a range of 14 meters.Read Replies (0)

Hackers allegedly working for the embattled Venezuelan government tried to trick activists into giving away their passwords to popular services such as Gmail, Facebook, Twitter, and others, according to security researchers. From a report: Last week, the Venezuelan opposition leader Juan Guaido called for citizens to volunteer with the goal of helping international humanitarian organizations deliver aid into the country. President Nicolas Maduro is refusing to accept aid and has erected blocks across a border bridge with Colombia with the military's help. The volunteer efforts were organized around the website voluntariosxvenezuela.com. A week later, on February 11 someone registered an almost identical domain, voluntariosvenezuela[.]com. And on Wednesday, users in Venezuela who were trying to visit the original and official VoluntariosxVenezuela website were redirected to the newer one, according to security firm Kaspersky Lab, as well as Venezuelan users on Twitter.Read Replies (0)

As you may have noticed, Facebook is not cool anymore. The social juggernaut has been mired in controversies -- infamous privacy scandals or company's ruthless "grow fast and break things" approach to gain users, to name a few. Luckily enough, some people are trying to build new social networks and are coming up with interesting original ideas. Minds.com is one such social network.
The open source social network, which has been operational since 2012, works on a point-earning/exchange system to give users full control over the reach of their posts. One of the complaints people have with Facebook and Twitter is that they feel their posts are not being seen by all of their friends. Minds.com lets users earn points and then trade those points to boost their posts on the platform. Users earn tokens by being active on the platform and engaging in uploading, voting, commenting and other similar activities. They can then use these tokens, which can be exchanged within the platform, to boost the reach of their posts. The company last year launched a cryptocurrency reward program based on the ethereum blockchain for all users on the platform. Minds says it does not determine what should be censored. Users are free to post whatever they want. (You can follow us on Minds.)
We are excited to announced that Minds founder and chief executive Bill Ottman has agreed to do an interview with us. If you have a question about Minds.com for him or his take on the current social networking space, feel free to ask it in the comments section below.Read Replies (0)

Slashdot reader Drakster writes: Hollywood producer and writer James Cameron, who is best known for his first two Terminator films, Titanic, Avatar, and Aliens, has released his most recent film this week, Alita: Battle Angel, to mostly mixed to positive reviews. First announced in 2003, based on Yukito Kishiro's Gunnm manga series, it was stuck in development for several years, finally starting production in 2008. Slashdot last discussed this fifteen years ago, so now that it's finally here. For those who have seen it, what did you think? Met or surpassed your expectations, or not worth the wait?Read Replies (0)

An anonymous reader quotes a report from CNBC: In a not-too-distant future, renewable energy becomes the world's biggest source of power generation. A quarter of the distances that humans travel by vehicle will be in electric cars. U.S. dominance in the oil market begins to wane, and OPEC's influence is resurgent, as crude demand finally peaks. That is the vision laid out by British oil and gas giant BP on Thursday in its latest Annual Energy Outlook. The closely followed report lays out a vision through 2040 for Earth's energy future, provided government policy, technology and consumer preferences evolve in line with recent trends. BP forecasts that the world's energy demand will grow by a third through 2040, driven by rising consumption in China, India and other parts of Asia. About 75 percent of that increase will come from the need to power industry and buildings. At the same time, energy demand will continue to grow in the transportation sector, but that growth will slow sharply as vehicles become more efficient and more consumers opt for electric cars. But despite the increase in supply, BP thinks two-thirds of the world's population will still live in places with relatively low energy consumption per head. The takeaway: The world will need to generate more energy. The report says natural gas consumption will grow by 50 percent over the next 20 years, increasing in virtually every corner of the globe. "Throughout most of that time, the world will continue to consume more oil year after year, until demand ultimately peaks around 108 million barrels per day in the 2030s," reports CNBC. "This year, OPEC expects global oil demand to reach 100 million bpd."
