The Most Copied StackOverflow Java Code Snippet Contains a Bug
The admission comes from the author of the snippet itself, Andreas Lundblad, a Java developer at Palantir, and one of the highest-ranked contributors to StackOverflow, a Q&A website for programming-related topics. From a report: An academic paper [PDF] published in 2018 identified a code snippet Lundblad posted on the site as the most copied Java code taken from StackOverflow and then re-used in open source projects. The code snippet was provided as an answer to a StackOverflow question posted in September 2010. The code snippet printed byte counts (123,456,789 bytes) in a human-readable format, like 123.5 MB. Academics found that this code had been copied and embedded in more than 6,000 GitHub Java projects, more than any other StackOverflow Java snippet. In a blog post published last week, Lundblad said that the code had a flaw as it incorrectly converted byte counts into human-readable formats. Lundblad said he revisited the code after learning of the academic paper and its results. He looked at the code again and published a corrected version on his blog.

US Shows a 'Concerning Lack of Regard For the Privacy of People's Biometrics'
Mark Wilson shares a report from BetaNews: When it comes to the extensive and invasive use of biometric data, the USA is one of the worst offenders in the world, faring only slightly better than China. According to research conducted by Comparitech, which rated 50 countries according to how, where and why biometrics were taken and how they are stored, the U.S. ranked as the fourth worst country. Topping the list is China, followed by Malaysia and Pakistan. While Comparitech did not look at every country in the world, its study did compare 50 of them. To give a country a rating out of 25, each was rated out of five in four categories (storage, CCTV, workplace, and visas) according to how invasive and pervasive and the collection and use of biometrics is. Five questions were also applied to them, with each answer in the affirmative resulting in one point. [The five questions are available in the report.] The U.S. was assigned a score of 20/25 for its heavy use of biometrics, including growing use of facial recognition, without there being specific laws to protect citizens' data. There was concern at the growing use of biometrics in the workplace. At the other end of the league are Ireland and Portugal, both praised for their small or non-existent biometric databases. Both scored 11 points.

Ford Will Turn McDonald's Used Coffee Bean Husks Into Car Parts
Ford will soon start using coffee chaff from McDonald's to manufacture auto parts like headlamp housings and other interior and exterior components. "In addition to making Ford vehicles a little bit 'greener,' the coffee chaff -- or the waste produced by coffee during the roasting process -- will apparently also help the company make parts that are 20 percent lighter," reports Engadget. From the report: Ford already uses various sustainable materials like soy and tree cellulose in an effort to only use recycled and renewable plastics in its vehicles. It has added coffee chaff to the list after its research team discovered that it can be turned into a durable product by heating it to high temperatures under low oxygen and mixing it with additives like plastic. The material will then be turned into pellets that can be formed into various shapes. During the team's tests, they found that the chaff-based material has "significantly better" heat properties than the current material Ford is using. They also discovered that it'll allow the company to enjoy 25 percent energy savings during the molding process. McDonald's is expected to earmark a significant portion of the coffee chaff its North American operations produce for this project. While it's not entirely clear how much chaff that is, McD's generates 62 million pounds of chaff a year in the continent alone, which is currently just used to make coal and garden mulch.
