Apple cofounder Steve Wozniak has formally deactivated his Facebook account. In an email interview with USA Today, Wozniak wrote that he was no longer satisfied with Facebook, knowing that it makes money off of user data. "The profits are all based on the user's info, but the users get none of the profits back," he wrote. "Apple makes its money off of good products, not off of you. As they say, with Facebook, you are the product." Ars Technica reports: His Sunday announcement to his Facebook followers came just ahead of Facebook CEO Mark Zuckerberg's scheduled testimony before Congress on Tuesday. The CEO is also reportedly set to meet with members of Congress privately on Monday. Wozniak wrote that Facebook had "brought me more negatives than positives." Still, when Wozniak tried to change some of his privacy settings in the aftermath of Cambridge Analytica, he said he was "surprised" to find out how many categories for ads he had to remove. "I did not feel that this is what people want done to them," added Wozniak. "Ads and spam are bad things these days and there are no controls over them. Or transparency."

An anonymous reader quotes a report from The Verge: Microsoft is releasing the source code for its original Windows File Manager from nearly 28 years ago. Originally released for Windows 3.0, the File Manager was a replacement for managing files through MS-DOS, and allowed Windows users to copy, move, delete, and search for files. While it's a relic from the past, you can still compile the source code Microsoft has released and run the app on Windows 10 today. The source code is available on GitHub, and is maintained by Microsoft veteran Craig Wittenberg under the MIT license. Wittenberg copied the File Manager code from Windows NT 4 back in 2007, and has been maintaining it before open sourcing it recently. It's a testament to the backward compatibility of Windows itself, especially that this was originally included in Windows more than 20 years ago.

Nearly two-dozen privacy and children's advocacy groups have filed a Federal Trade Commission complaint against YouTube, alleging the platform of illegally collecting data from children. From a report: The groups, led by the Campaign for a Commercial-Free Childhood (CCFC), allege YouTube is violating the Children's Online Privacy Protection Act (COPPA) by collecting data from children under 13 without parents' permission.

"It's just fundamentally unfair," Josh Golin, executive director of the CCFC, told Gizmodo, "to use Google's powerful behavioral targeting on a child that doesn't yet understand what's going on." COPPA requires platforms "give parents notice of its data collection practices, and obtain verifiable parental consent before collecting the data." But, as Golin argues, YouTube violates COPPA because it doesn't differentiate between videos marketed to children and the rest of the site.

Amazon powered its prolific 2017, which saw the release of a cavalcade of new products and services, with $22.6 billion in spending on research and development, tops among U.S. companies. From a report: According to data from FactSet, Google parent Alphabet came in second in R&D spending in 2017 at $16.6 billion, followed by Intel at $13.1 billion, Microsoft at $12.3 billion and Apple at $11.6 billion. Facebook jumped into the top 10, spending $7.8 billion in 2017. One of Amazon's biggest R&D efforts in recent years has been the cashier-less grocery store concept Amazon Go. The company spent 2017 getting the technology, first announced in December 2016, ready for prime time before opening the first location in January. Amazon has invested heavily in its market-leading cloud computing arm, Amazon Web Services. AWS juiced Amazon.

A trade group representing top technology companies on Monday told U.S. Treasury Secretary Steven Mnuchin that it opposes the Trump administration's focus on tariffs to try to change China's unfair trade practices. From a report: The Information Technology Industry Council said in a letter to Mnuchin that it supports the Trump administration's "Section 301" investigation into China's abuses of intellectual property, but instead of tariffs, it advocates a U.S.-led international coalition to put pressure on Beijing. "Our opposition to tariffs is pragmatic. Tariffs do not work," wrote ITIC President and CEO Dean Garfield. "Instead of tariffs, we strongly encourage the administration to build an international coalition that can challenge China at the World Trade Organization and beyond," Garfield added. "Numerous countries share the United States' concerns about China and its unfair trade practices. The United States is uniquely well-situated to lead that coalition."

The West African nation of Mauritania lost all internet access for 48 hours due to an undersea cable break, according to infrastructure analysts. From a report: The break, which took place a couple weeks ago, provides a reminder of how much internet users rely on the cables that connect their countries. According to Dyn, the Oracle-owned internet performance firm, the African Coast to Europe (ACE) cable was cut near Noukachott in Mauritania on March 30. It's not clear what caused the break, but six countries entirely rely on that one cable for their connectivity, and all -- Sierra Leone, Mauritania, Liberia, Guinea-Bissau, Guinea and the Gambia -- saw a big impact. The impact in Mauritania was the worst, with its two-day outage, while Sierra Leone also had big problems. The latter country also had a big outage on April 1, but that may well have been down to government action -- African governments are notorious for interfering with citizens' internet access, particularly around election time or during periods of unrest.

We already know bots have a significant presence on Twitter. But a report published Monday by the Pew Research Center suggests automated accounts are more prevalent than we may previously have thought. From a report: Pew estimates that two-thirds, or about 66 percent, of the links shared on Twitter come from bots rather than people. The research specifically focused on the 2,315 most popular websites and over 1 million tweets sent between July 27 and Sept. 11, 2017.

An anonymous reader writes: It goes without saying that no tech CEO ever wants to make the trek down to Washington D.C. and appear before congress. And Zuckerberg -- at a surface level -- seems particularly ill-suited for the task. Though clearly an incredible mind, remember that Zuckerberg is a tech-minded programmer and far from a savvy and political operator. That being the case, many people are curious as to how the Facebook founder, who it's worth noting is just 33 years old, will fare when confronted with hard hitting questions from politicians.

In an effort to ensure that everything runs smoothly and that Zuckerberg's appearance goes off without a hitch, The New York Times is reporting that Facebook recently hired a team of experts and coaches tasked with ensuring that Zuckerberg has the tools to deftly navigate the potentially deep waters of Congress. Of particular interest is that Zuckerberg has been learning how to be charming and exhibit humility in the face of heavy-handed and probing questions. The report says, "It [ Facebook] has also hired a team of experts, including a former special assistant to President George W. Bush, to put Mr. Zuckerberg, 33, a cerebral coder who is uncomfortable speaking in public, through a crash course in humility and charm. The plan is that when he sits down before the Senate Commerce and Judiciary committees on Tuesday, Mr. Zuckerberg will have concrete changes to talk about, and no questions he can't handle."

Facebook suspended a company from its site over the weekend while it investigates claims it harvested user information under the guise of academic research, in a case with echoes of the Cambridge Analytica scandal. From a report: Facebook is suspending a data analytics firm called CubeYou from the platform after CNBC notified the company that CubeYou was collecting information about users through quizzes. CubeYou misleadingly labeled its quizzes "for non-profit academic research," then shared user information with marketers. The scenario is eerily similar to how Cambridge Analytica received unauthorized access to data from as many as 87 million Facebook user accounts to target political marketing. CubeYou, whose CEO denies any deception, sold data that had been collected by researchers working with the Psychometrics Lab at Cambridge University, similar to how Cambridge Analytica used information it obtained from other professors at the school for political marketing.

Blake Ellis and Melanie Hicken, writing for CNN: Two years ago, Brendan Tyne pleaded with the Food and Drug Administration to approve a drug that he was hopeful could finally bring his mother some peace. She could no longer move without assistance and had fallen victim to the debilitating and frightening psychosis that haunts many people with Parkinson's disease. "She thinks there are people in the house and animals are trying to get her," he told an FDA advisory committee. He believed that a new medication called Nuplazid, made by San Diego-based Acadia Pharmaceuticals, was the answer.

Nuplazid's review was being expedited because it had been designated a "breakthrough therapy" -- meaning that it demonstrated "substantial improvement" in patients with serious or life-threatening diseases compared to treatments already on the market. Congress created this designation in 2012 in an effort to speed up the FDA's approval process, which has long been criticized for being too slow. Around 200 drugs have been granted this designation since its creation. [...] The committee voted 12-2 and recommended that the FDA approve Nuplazid for the treatment of Parkinson's disease psychosis based on a six-week study of about 200 patients. It hit the market in June 2016. As caregivers and family members rushed to get their loved ones on it, sales climbed to roughly $125 million in 2017

[...] In November, an analysis released by a nonprofit health care organization, the Institute for Safe Medication Practices, warned that 244 deaths had been reported to the FDA between the drug's launch and March 2017. [...] Since the institute released its analysis, FDA data shows that the number of reported deaths has risen to more than 700. As of last June, Nuplazid was the only medication listed as "suspect" in at least 500 of the death reports.

john of sparta shares a report from Business Insider (Warning: source may be paywalled; alternative source): Reports of a crackdown on cryptocurrency advertisements by tech giants such as Google and Facebook as well as regulatory uncertainty in Asia and the U.S. have weighed on the coin for much of March and April. The coin is down 50% since the beginning of the year. But investors appeared to be more bullish during Sunday's trade following reports that two Wall Street icons were looking to get into the market for cryptos. More notably, the investment fund founded by billionaire George Soros is preparing to dive into cryptocurrency trading, even though Soros himself previously described them as a "bubble." Adam Fisher, who oversees global macroeconomic investing for Soros Fund Management, has gained internal approval to invest in and trade cryptocurrencies, according to a Bloomberg News report. Also, Venrock -- a venture capital firm founded by descendants of famed capitalist John D. Rockefeller -- announced it was partnering with a cryptocurrency investment firm based in Brooklyn. Fortune first reported on the partnership.

Fast Company's harrymcc writes: When technological goods are no longer of use to anyone in Silicon Valley, they end up in the WeirdStuff Warehouse -- where, it turns out, there often is someone willing to pay for them. Sadly, the 32-year-old Sunnyvale store is closing forever on Sunday. I paid a final visit and, as usual, felt like I could rummage through this vast storehouse of obsolete gadgets and software forever. WeirdStuff first made an appearance on Slashdot in 2003 when editor chrisd asked Slashdotters about their favorite surplus stores. Also mentioned was Skycraft.

PolygamousRanchKid shares a report from CNN: Cambridge Analytica whistleblower Christopher Wylie says the data the firm gathered from Facebook could have come from more than 87 million users and could be stored in Russia. Wylie added that his lawyer has been contacted by U.S. authorities, including congressional investigators and the Department of Justice, and says he plans to cooperate with them. Aleksander Kogan, a Russian data scientist who gave lectures at St. Petersburg State University, gathered Facebook data from millions of Americans. He then sold it to Cambridge Analytica, which worked with President Donald Trump's 2016 presidential campaign. "I know that Facebook is now starting to take steps to rectify that and start to find out who had access to it and where it could have gone, but ultimately it's not watertight to say that, you know, we can ensure that all the data is gone forever," he said.

British electrical engineer John Barstead created a sonar alarm system that will warn parents or nearby sunbathers if a small child has accidentally fallen into a pool. The Dolphin Alarm, as it is called, is currently raising production funds on Kickstarter. New Atlas explains how it works: When small children who have no business going into the pool on their own are out playing near it, they wear a special wristband. If they should fall in, the wristband will generate a three-tone sonar signal as soon as it's immersed in the water. That signal will be detected by a hydrophone contained within a receiver unit that floats in the pool. When that happens, the unit will emit a 131-decibel alarm. It will also transmit an alert to an indoor remote unit located up to 150 m away (170 ft), which will likewise sound an alarm of its own. While there are other child-in-the-pool alarms, most of them are wave-activated and have to be shut off when other people are using the pool.
