Submission + - 40,000 Chromebooks and 9,600 iPads Go Missing at Chicago Public Schools

theodp writes: "When the school system [Chicago Public Schools] shifted to having students learn remotely in the spring of 2020 near the beginning of the pandemic, it lent students iPads, MacBooks and Windows computer devices so they could do school work and attend virtual classes from home," reports Frank Main in the Chicago Sun-Times. "CPS then spent about $165 million to buy Chromebook desktop computers so that every student from kindergarten through senior year in high school who needed a computer could have one. Students borrowed 161,100 Chromebooks in September 2020. By June 2021, more than 210,000 of those devices had been given out. Of them, nearly 40,000 Chromebooks have been reported lost — nearly a fifth of those that were lent. 'Schools have made repeated efforts to recover the lost devices from families without success,' according to a written statement from CPS officials in response to questions about the missing school property. Also missing are more than 9,600 iPads, 114 televisions, 1,680 printers and 1,127 audiovisual projectors, among many other items. Officials say CPS has bought new computer devices to replace the missing ones."

There were 340,658 students enrolled in the Chicago Public Schools (CPS) at the start of the 2020-2021 school year.

schwit1 writes: “A nitrogen doped carbon-coated nickel anode can catalyze an essential reaction in hydrogen fuel cells at a fraction of the cost of the precious metals currently used, Cornell University researchers have found. The new discovery could accelerate the widespread use of hydrogen fuel cells, which hold great promise as efficient, clean energy sources for vehicles and other applications.”

When I first seriously started thinking of smart grid applications back in 2002... this is what I thought they would be using...

Why implement a step back in tech when they could do BPL? Seems like it is drastically more realistic(see cheaper) in implementation than a wireless network.

The Twitter Book 88

stoolpigeon writes "Microblogging service Twitter has undeniably been a hit, with growth rates that were at times in excess of 1400%. The growth was rapid enough that the site became well known for its periodic, and, at times, extensive downtime. Even with these issues, the service continued to grow rapidly, and with celebrities getting into the mix Twitter was quickly on the radar of mainstream media. The ubiquity of Twitter and ever-increasing coverage of 'tweets' has also brought the inevitable backlash. As with anything that gains high-profile popularity, there are plenty of Twitter haters out there, though the role Twitter has played in the recent Iranian elections seems to have brought more legitimacy to Twitter in the eyes of many. With popularity come books, and quite a few are already out there about and for Twitter, but my favorite so far is The Twitter Book by Tim O'Reilly and Sarah Milstein."
