White House Silence Seems To Confirm $4 Billion 'Computer Science For All' K-12 Initiative Is No More

Tue, 06 Dec 2016 10:00:00

theodp writes: "2016 as a year of action builds on a decade of national, state, and grassroots activity to revitalize K-12 computer science education," reads the upbeat White House blog post kicking off Computer Science Education Week. But conspicuous by its absence in the accompanying fact sheet for A Year of Action Supporting Computer Science for All is any mention of the status of President Obama's proposed $4 billion Computer Science For All initiative, which enjoyed support from the likes of Microsoft, Facebook, and Google. On Friday, tech-backed Code.org posted An Update on Computer Science Education and Federal Funding, which explained that Congress's passage of a 'continuing resolution' extending the current budget into 2017 spelled curtains for federal funding for the program in 2016 and beyond. "We don't have any direct feedback yet about the next administration's support for K-12 CS," wrote CEO Hadi Partovi and Govt. Affairs VP Cameron Wilson, "other than a promise to expand 'vocational and technical education' as part of Trump's 100-day plan which was published in late October. I am hopeful that this language may translate into support for funding K-12 computer science at a federal level. However, we should assume that it will not."

Facebook Begins Asking Users To Rate Articles' Use of 'Misleading Language'

Tue, 06 Dec 2016 07:00:00

Facebook is finally cracking down on the fake news stories that run rampant on its site and many other social media sites across the web. The company is rolling out a new feature in the form of a survey that asks users to rate articles' use of "misleading language." The feedback received will likely help Facebook train its algorithms to better detect misleading headlines. TechCrunch reports: The "Facebook Survey," noticed by Chris Krewson of Philadelphia's Billy Penn, accompanied (for him) a Philadelphia Inquirer article about the firing of a well-known nut vendor for publicly espousing white nationalist views. "To what extent do you think that this link's title uses misleading language?" asks the "survey," which appears directly below the article. Response choices range from "Not at all" to "Completely," though users can also choose to dismiss it or just scroll past. Facebook confirmed to TechCrunch that this is an official effort, though it did not answer several probing questions about how it works, how the data is used and retained, and so on. The company uses surveys somewhat like this to test the general quality of the news feed, and it has used other metrics to attempt to define rules for finding clickbait and fake stories. This appears to be the first direct coupling of those two practices: old parts doing a new job.

California State Senator Introduces Bill That Would Mandate Reporting of 'Superbug' Infections, Deaths

Tue, 06 Dec 2016 03:30:00

An anonymous reader quotes a report from Reuters: A California state senator introduced a bill on Monday that would mandate reporting of antibiotic-resistant infections and deaths and require doctors to record the infections on death certificates when they are a cause of death. The legislation also aims to establish the nation's most comprehensive statewide surveillance system to track infections and deaths from drug-resistant pathogens. Data from death certificates would be used to help compile an annual state report on superbug infections and related deaths. In September, a Reuters investigation revealed that tens of thousands of superbug deaths nationwide go uncounted every year. The infections are often omitted from death certificates, and even when they are recorded, they aren't counted because of the lack of a unified national surveillance system. Because there is no federal surveillance system, monitoring of superbug infections and deaths falls to the states. A Reuters survey of all 50 state health departments and the District of Columbia found that reporting requirements vary widely. Hill's bill would require hospitals and clinical labs to submit an annual summary of antibiotic-resistant infections to the California Department of Health beginning July 1, 2018; amend a law governing death certificates by requiring that doctors specify on death certificates when a superbug was the leading or a contributing cause of death; and require the state Health Department to publish an annual report on resistant infections and deaths, including data culled from death certificates.

Windows 10 'Home Hub' Is Microsoft's Response To Amazon Echo and Google Home

Tue, 06 Dec 2016 01:05:00

Microsoft's response to the Amazon Echo and Google Home is Home Hub, a software update for Windows 10's Cortana personal assistant that turns any Windows PC into a smart speaker of sorts. Mashable reports: Microsoft's smart digital assistant Cortana can already answer your queries, even if the PC's screen is locked. The Home Hub is tied to Cortana and takes this a few steps further. It would add a special app with features such as calendar appointments, sticky notes and shopping lists. A Home Hub-enabled PC might have a Welcome Screen, a full-screen app that displays all these, like a virtual fridge door. Multiple users (i.e. family members) could use the Home Hub, either by authenticating through Windows Hello or by working in a family-shared account. Cortana would get more powerful on Home Hub; it could, for example, control smart home devices, such as lights and locks. And even though all of this will work on any Windows 10 device -- potentially making the PC the center of your smart home experience -- third-party manufacturers will be able to build devices that work with Home Hub. You can read Windows Central's massive report here. Do note that Home Hub is not official and individual features could change over time. The update is slated for 2017.

Fake News Prompts Gunman To 'Self-Investigate' Pizza Parlor

Tue, 06 Dec 2016 00:20:00

An anonymous reader quotes a report from Ars Technica: A rifle-wielding North Carolina man was arrested Sunday in Washington, DC for carrying his weapon into a pizzeria that sits at the center of the fake news conspiracy theory known as "Pizzagate," authorities said Monday. DC's Metropolitan Police Department said it had arrested 28-year-old Edgar Maddison Welch on allegations of assault with a dangerous weapon. "During a post arrest interview this evening, the suspect revealed that he came to the establishment to self-investigate 'Pizza Gate' (a fictitious online conspiracy theory," the agency said in a statement. "Pizzagate" concerns a baseless conspiracy theory about a secret pedophile group, the Comet Ping Pong restaurant, and Hillary Clinton's campaign chief, John Podesta. The Pizzagate conspiracy names Comet Ping Pong as the secret headquarters of a non-existent child sex-trafficking ring run by Clinton and members of her inner circle. James Alefantis, the restaurant's owner, said he has received hundreds of death threats. According to Buzzfeed, the Pizzagate theory is believed to have been fostered by a white supremacist's tweets, the 4chan message board, Reddit, Donald Trump supporters, and right-wing blogs. The day before Thanksgiving, Reddit banned a "Pizzagate" conspiracy board from the site because of a policy about posting personal information of others. Alefantis, the pizzeria's owner, told CNN, "What happened today demonstrates that promoting false and reckless conspiracy theories comes with consequences. I hope that those involved in fanning these flames will take a moment to contemplate what happened here today, and stop promoting these falsehoods right away."
