The U.S. saw its highest level of layoffs in a first quarter since 2009, data from staffing firm Challenger, Gray & Christmas released this week showed. From a report: Employers cut 190,410 jobs in the first 3 months of the year -- 10.3% higher than the number of layoffs announced in the fourth quarter of 2018 and 35.6% higher than job cuts announced in the same quarter of 2018. It's the highest number of job cuts in a quarter since 2015. The financial industry saw the third highest number of layoffs and the year-to-date total was 239% higher than it was in 2018.

An anonymous reader shares a report: If it's been a few years since you shopped for a lightbulb, you might find yourself confused. Those controversial curly-cue ones that were cutting edge not that long ago? Gone. (Or harder to find.) Thanks to a 2007 law signed by President George W. Bush, shelves these days are largely stocked with LED bulbs that look more like the traditional pear-shaped incandescent version but use just one-fifth the energy. A second wave of lightbulb changes was set to happen. But now the Trump administration wants to undo an Obama-era regulation designed to make a wide array of specialty lightbulbs more energy efficient.

At issue here are bulbs such as decorative globes used in bathrooms, reflectors in recessed lighting, candle-shaped lights and three-way lightbulbs. The Natural Resources Defense Council says that, collectively, these account for about 2.7 billion light sockets, nearly half the conventional sockets in use in the U.S. At the very end of the Obama administration, the Department of Energy decided these specialty bulbs should also be subject to efficiency requirements under the 2007 law. The lighting industry objected and sued to overturn the decision. [...] NEMA argued that Congress never intended for the law to apply to all these other lightbulbs. After President Trump took office the Energy Department agreed and proposed to reverse the agency's previous decision. Critics say if the reversal is finalized it will mean higher energy bills for consumers and more pollution.

EU lawmakers today endorsed an overhaul of the bloc's two-decade old copyright rules, which will force Google and Facebook to pay publishers for use of news snippets and make them filter out protected content. From a report: The set of copyright rules known as the Directive on Copyright in the Digital Single Market, but more succinctly as the EU Copyright Directive, has been debated and discussed for several years. While it is broadly uncontroversial in many regards, there are two facets to the directive that has caused the internet to freak out. Article 11, which has been dubbed the "link tax," stipulates that websites pay publishers a fee if they display excerpts of copyrighted content -- or even link to it. This obviously could have big ramifications for services such as Google News. Then there is Article 13, dubbed the "upload filter," which would effectively make digital platforms legally liable for any copyright infringements on their platform, which has stoked fears that it would stop people from sharing content -- such as GIF-infused memes -- on social networks. In a statement, EFF said, "In a stunning rejection of the will five million online petitioners, and over 100,000 protestors this weekend, the European Parliament has abandoned common-sense and the advice of academics, technologists, and UN human rights experts, and approved the Copyright in the Digital Single Market Directive in its entirety."

The Wall Street Journal is reporting that the United States has told Germany to drop Huawei from its future plans or risk losing access to some U.S. intelligence. The U.S. says the Chinese company's equipment could be used for espionage -- a concern that Huawei says is unfounded. "The Trump administration has been pressing allies to end their relationships with Huawei, but Germany, moving ahead with its plans, has not moved to ban the company from its networks," reports The Verge. From the report: According to the Journal, a letter sent from the U.S. Ambassador to Germany warns the country that the U.S. will stop sharing some secrets if it allows Huawei to work on its next-generation 5G infrastructure. The letter, according to the Journal, argues that network security can't be effectively managed by audits of equipment or software. While the U.S. plans to continue sharing intelligence with Germany regardless, the Journal reports, officials plan to curtail the scope of that information if Huawei equipment is used in German infrastructure.

It's now easier than ever in France to act out Star Wars fantasies. The country's fencing federation has officially recognized lightsaber dueling as a competitive sport, granting the weapon from George Lucas's space saga the same status as the foil, epee and sabre, the traditional blades used at the Olympics. From a report: Of course, the LED-lit, rigid polycarbonate replicas can't slice an opponent in half. But they look and sound remarkably like the blades that Yoda and other characters wield in the blockbuster movies. The physicality of lightsaber combat is part of the reason why the French Fencing Federation is now equipping fencing clubs with lightsabers and training would-be lightsaber instructors. Like virtuous Jedi knights, the federation sees itself as combatting a Dark Side: the sedentary habits of 21st-century life.

"With young people today, it's a real public health issue. They don't do any sport and only exercise with their thumbs," says Serge Aubailly, the federation's secretary general. "That is why we are trying to create a bond between our discipline and modern technologies, so participating in a sport feels natural." In the past, Zorro, Robin Hood and The Three Musketeers helped lure new practitioners to fencing. Now, Luke Skywalker, Obi-Wan Kenobi and Darth Vader are joining them. "Cape-and-sword movies have always had a big impact on our federation and its growth," Aubailly says. "Lightsaber films have the same impact. Young people want to give it a try."

The Federal Communications Commission will consider "regulatory intervention" if the major telecommunications carriers don't set up a system this year to stop spoofed robocalls, FCC chairman Ajit Pai said Wednesday. "It's time for carriers to implement robust caller ID authentication," Pai said in a statement, noting that some companies have already committed to carrying out protocols, known as the SHAKEN/STIR framework, in 2019. A report adds: Pai sent letters to major wireless carriers in November demanding that they adopt industry-wide frameworks to crackdown on the practice of "spoofing," where robocallers mask a call's origin with a fraudulent number on their caller ID. On Wednesday, the FCC chair followed up with another demand that they implement caller authentication systems this year and a threat over the repercussions if they don't comply. You can read responses from carriers FCC's website.

A federal appeals court has overturned Ajit Pai's attempt to take broadband subsidies away from tribal residents. From a report: The Pai-led Federal Communications Commission voted 3-2 in November 2017 to make it much harder for tribal residents to obtain a $25-per-month Lifeline subsidy that reduces the cost of Internet or phone service. The change didn't take effect because in August 2018, the US Court of Appeals for the District of Columbia Circuit stayed the FCC decision pending appeal. The same court followed that up on Friday last week with a ruling that reversed the FCC decision and remanded the matter back to the commission for a new rule-making proceeding. [...] The Pai FCC's 2017 decision would have limited the $25 subsidy to "facilities-based" carriers -- those that build their own networks -- making it impossible for tribal residents to use the $25 subsidy to buy telecom service from resellers. The move would have dramatically limited tribal residents' options for purchasing subsidized service, but the FCC claimed it was necessary in order to encourage carriers to build their own networks.

This week HackerRank reported Java is now only the second most popular programming language, finally dropping behind JavaScript in the year 2018.

Now long-time Slashdot reader shanen asks about the rumors that Java is dead -- or is it?

Can you convince me that Java isn't as dead as it seems? It's just playing dead and will spring to life?
This week one Java news site argued that Java-based Minecraft has in fact "spawned a new generation of Java developers," citing an interview with Red Hat's JBoss Middleware CTO. (And he adds that "It's still the dominant programming language in the enterprise, so whether you're building enterprise clients, services or something in between, Java likely features in there somewhere.") Yet the original submission drew some interesting comments:

• "The licensing scheme for Java kills it..."

• "Java programs still are 'the alien on your desktop'. They suck in many ways. Users have learned to avoid them and install 'real programs' instead..."

But what do Slashdot's readers think? Leave your own answers in the comments.

How dead is Java?

Canonical today announced the release of Ubuntu Core 18 "for secure, reliable IoT devices." The Canonical blog notes that "Immutable, digitally signed snaps ensure that devices built with Ubuntu Core are resistant to corruption or tampering. Any component can be verified at any time." In addition, "The attack surface of Ubuntu Core has been minimized, with very few packages installed in the base OS, reducing the size and frequency of security updates and providing more storage for applications and data." Ubuntu Core also "enables a new class of app-centric things, which can inherit apps from the broader Ubuntu and Snapcraft ecosystems or build unique and exclusive applications that are specific to a brand or model."

An anonymous reader quotes a report from CNET: LG's next smartphone may have you seeing double. And no, it's not because of a foldable display. The company will launch a smartphone, whose name hasn't been finalized, that will have an option for a second-screen attachment, according to a person familiar with the situation. The attachment, which the person describes as a sort of case with a screen, could potentially double the total screen size of the device. It's one of multiple phones launching at the Mobile World Congress trade show next month, the person said. While the company is mulling the G8 name, it's unclear whether the multiple-screen phone will carry the name of its flagship line. There was some confusion over LG launching a foldable smartphone thanks to a report by Korean-language outlet Naver. But this phone won't fold.

Engineers at the University of California, Berkeley, have developed a new neurostimulator that can listen to and stimulate electric current in the brain at the same time, potentially delivering fine-tuned treatments for patients with diseases like epilepsy and Parkinson's. Science Daily reports: The device, named the WAND, works like a "pacemaker for the brain," monitoring the brain's electrical activity and delivering electrical stimulation if it detects something amiss. These devices can be extremely effective at preventing debilitating tremors or seizures in patients with a variety of neurological conditions. But the electrical signatures that precede a seizure or tremor can be extremely subtle, and the frequency and strength of electrical stimulation required to prevent them is equally touchy. It can take years of small adjustments by doctors before the devices provide optimal treatment.

WAND, which stands for wireless artifact-free neuromodulation device, is both wireless and autonomous, meaning that once it learns to recognize the signs of tremor or seizure, it can adjust the stimulation parameters on its own to prevent the unwanted movements. And because it is closed-loop -- meaning it can stimulate and record simultaneously -- it can adjust these parameters in real-time. WAND can record electrical activity over 128 channels, or from 128 points in the brain, compared to eight channels in other closed-loop systems. To demonstrate the device, the team used WAND to recognize and delay specific arm movements in rhesus macaques. The device is described in a study that appeared in Nature Biomedical Engineering.

A gene editing technique has been used to produce asexual rice, which could carry traits such as high yields and drought resistance. From a report: After more than 20 years of theorizing about it, scientists have tweaked a hybrid variety of rice so that some of the plants produce cloned seeds. No plant sex necessary. The feat, described earlier this month in Nature, is encouraging for efforts to feed an increasingly crowded world. Crossing two good varieties of grain can make one fabulous one, combining the best versions of genes to give crops desirable traits such as higher yields. But such hybrid grain marvels often don't pass along those coveted genetic qualities to all seeds during reproduction. So farmers who want consistently higher yields have to pay for new hybrid seeds every year.

This new lab version of hybrid rice would preserve those qualities through self-cloning, says study coauthor Venkatesan Sundaresan, a plant geneticist at the University of California, Davis. Though 400 kinds of plants, including some blackberries and citruses, have developed self-cloning seeds naturally, re-creating those pathways in crop plants has "been harder than anyone expected," Sundaresan says. He and his colleagues got the idea for the new research while studying "how a fertilized egg becomes a zygote, this magical cell that regenerates an entire organism," as Sundaresan puts it. The researchers discovered that modifying two sets of genes caused the japonica rice hybrid called Kitaake to clone its own seeds. First the team found that in a fertilized plant egg, only the male version of a gene called BABY BOOM1 found in sperm triggered the development of a seed embryo. So the scientists inserted a genetic starter switch, called a promoter, that let the female version of the same gene do the same job. No male would be necessary to trigger an embryo's development.

President Donald Trump on Monday rejected a central conclusion of a dire report on the economic costs of climate change released by his own administration. Associated Press reports: But economists said the National Climate Assessment's warning of hundreds of billions of dollars a year in global warming costs is pretty much on the money. Just look at last year with Hurricanes Harvey, Maria and Irma, they said. Those three 2017 storms caused at least $265 billion in damage, according to the National Oceanic and Atmospheric Administration. The climate report, quietly unveiled Friday, warned that natural disasters are worsening in the United States because of global warming. It said warming-charged extremes "have already become more frequent, intense, widespread or of long duration." The report noted the last few years have smashed U.S. records for damaging weather, costing nearly $400 billion since 2015.

"The potential for losses in some sectors could reach hundreds of billions of dollars per year by the end of this century," the report said. It added that if emissions of heat-trapping gases continue at current levels, labor costs in outdoor industries during heat waves could cost $155 billion in lost wages per year by 2090. The president said he read some of the report and "it's fine" but not the part about the devastating economic impact. "I don't believe it," Trump said, adding that if "every other place on Earth is dirty, that's not so good."

President Donald Trump has accused Twitter of targeting his followers for removal from the social media platform, amid complaints by conservatives that social media companies have been discriminating against right-wing voices. From a report: "Twitter has removed many people from my account and, more importantly, they have seemingly done something that makes it much harder to join -- they have stifled growth to a point where it is obvious to all," Trump said in a tweet Friday. "A few weeks ago it was a Rocket Ship, now it is a Blimp! Total Bias?" Trump and some other Republicans have complained that Facebook, Alphabet's Google and Twitter have censored or suppressed conservative voices. Democrats have called that a diversion from concern over Russia's use of social-media platforms to influence the 2016 presidential election and over the proliferation of offensive content. In his opening remarks during a meeting with state attorneys general in September, Attorney General Jeff Sessions raised concerns that social media companies have a political agenda and have the power to manipulate public opinion, according to Maryland Attorney General Brian Frosh.
