An anonymous reader quotes a report from Ars Technica: After ditching the traditional Dell XPS laptop look in favor of the polarizing design of the XPS 13 Plus released in 2022, Dell is killing the XPS branding that has become a mainstay for people seeking a sleek, respectable, well-priced PC. This means that there won't be any more Dell XPS clamshell ultralight laptops, 2-in-1 laptops, or desktops. Dell is also killing its Latitude, Inspiron, and Precision branding, it announced today. Moving forward, Dell computers will have either just Dell branding, which Dell's announcement today described as "designed for play, school, and work," Dell Pro branding "for professional-grade productivity," or be Dell Pro Max products, which are "designed for maximum performance." Dell will release Dell and Dell Pro-branded displays, accessories, and "services," it said. The Pro Max line will feature laptops and desktop workstations with professional-grade GPU capabilities as well as a new thermal design. Dell claims its mid-tier Pro line emphasizes durability, "withstanding three times as many hinge cycles, drops, and bumps from regular use as competitor devices." The statement is based on "internal analysis of multiple durability tests performed" on the Dell Pro 14 Plus (released today) and HP EliteBook 640 G11 laptops conducted in November. Also based on internal testing conducted in November, Dell claims its Pro PCs boost "airflow by 20 percent, making these Dell's quietest commercial laptops ever." Within each line are base models, Plus models, and Premium models. In a blog post, Kevin Terwilliger, VP and GM of commercial, consumer, and gaming PCs at Dell, explained that Plus models offer "the most scalable performance" and Premium models offer "the ultimate in mobility and design." By those naming conventions, old-time Dell users could roughly equate XPS laptops with new Dell Premium products. [...] Dell will maintain its Alienware line of gaming PCs and peripherals (Dell acquired Alienware in 2006). The changes were made to create more "unified branding" that will make it "easier and faster to find the right PCs, accessories, and services," said Dell in a press release. It also serves to push the company's "AI PCs" onto consumers. Dell notes that it will maintain its Alienware line of gaming PCs and peripherals "that's been service PC gamers for nearly 30 years."

Ward Christensen, co-inventor of the computer bulletin board system (BBS), has died at age 78 in Rolling Meadows, Illinois. He was found deceased at his home on Friday after friends requested a wellness check. Christensen, along with Randy Suess, created the first BBS in Chicago in 1978, leading to an important cultural era of digital community-building that presaged much of our online world today.

In the 1980s and 1990s, BBSes introduced many home computer users to multiplayer online gaming, message boards, and online community building in an era before the Internet became widely available to people outside of science and academia. It also gave rise to the shareware gaming scene that led to companies like Epic Games today.

Friends and associates remember Christensen as humble and unassuming, a quiet innovator who never sought the spotlight for his groundbreaking work. Despite creating one of the foundational technologies of the digital age, Christensen maintained a low profile throughout his life, content with his long-standing career at IBM and showing no bitterness or sense of missed opportunity as the Internet age dawned.

After more than nine months in an unusual, highly elliptical orbit, the US military's X-37B spaceplane will soon begin dipping its wings into Earth's atmosphere to lower its altitude before eventually coming back to Earth for a runway landing, the Space Force said Thursday.

The aerobraking maneuvers will use a series of passes through the uppermost fringes of the atmosphere to gradually reduce its speed with aerodynamic drag while expending minimal fuel. In orbital mechanics, this reduction in velocity will bring the apogee, or high point, of the X-37B's orbit closer to Earth.

Bleeding energy

The Space Force called the aerobraking a "novel space maneuver" and said its purpose was to allow the X-37B to "safely dispose of its service module components in accordance with recognized standards for space debris mitigation."

Tesla has issued a recall for effectively every Cybertruck it’s delivered to customers due to a fault that’s causing the vehicle’s accelerator pedal to get stuck.

According to the National Highway Traffic Safety Administration (NHTSA) on Wednesday, the defect can result in the pedal pad dislodging and becoming trapped in the vehicle’s interior trim when “high force is applied.”

The fault was caused by an “unapproved change” that introduced “lubricant (soap)” during the assembly of the accelerator pedals, which reduced the retention of the pad, the recall notice states. The truck’s brakes will still function if the accelerator pedal becomes trapped, though this obviously isn’t an ideal workaround.

The recall impacts “all Model Year (‘MY’) 2024 Cybertruck vehicles manufactured from November 13, 2023, to April 4, 2024,” with the fault estimated to be present in 100 percent of the total 3,878 vehicles. This is essentially every Cybertruck delivered to customers since its launch event last year.

A recall seemed to be inevitable after Cybertruck customers were reportedly notified earlier this week that their deliveries were being delayed, with at least one owner being informed by their vehicle dealership that the truck was being recalled over its accelerator pedal. The issue was also highlighted by another Cybertruck owner on TikTok, showing how the fault “held the accelerator down 100 percent, full throttle.”

The timeline reported in the NHTSA filing says that Tesla was first notified of the defective accelerator pedals on March 31st, followed by a second report on April 3rd. The company completed internal assessments to find the cause on April 12th before voluntarily issuing a recall. As of Monday this week, Tesla said it isn’t aware of any “collisions, injuries, or deaths” attributed to the pedal fault.

Tesla is notifying its stores and service centers of the issue “on or around” April 19th and has committed to replacing or reworking the pedals on recalled vehicles at no charge to Cybertruck owners. Any trucks produced from April 17th onward will also be equipped with a new accelerator pedal component and part number.

This is actually the second of Tesla’s many recalls to affect the Cybertruck, but it is the most significant. The company issued a recall for 2 million Tesla vehicles in the US back in February due to the font on the warning lights panel being too small to comply with safety standards, though this was resolved with a software update.

Tesla fans have taken issue with the word “recall” in the past when the company has proven adept at fixing its problems through over-the-air software updates. But they likely will have to admit that, in this case, the terminology applies.

Keaton Peters reports via the Texas Tribune: Students sitting for their STAAR exams this week will be part of a new method of evaluating Texas schools: Their written answers on the state's standardized tests will be graded automatically by computers. The Texas Education Agency is rolling out an "automated scoring engine" for open-ended questions on the State of Texas Assessment of Academic Readiness for reading, writing, science and social studies. The technology, which uses natural language processing technology like artificial intelligence chatbots such as GPT-4, will save the state agency about $15-20 million per year that it would otherwise have spent on hiring human scorers through a third-party contractor. The change comes after the STAAR test, which measures students' understanding of state-mandated core curriculum, was redesigned in 2023. The test now includes fewer multiple choice questions and more open-ended questions -- known as constructed response items. After the redesign, there are six to seven times more constructed response items. "We wanted to keep as many constructed open ended responses as we can, but they take an incredible amount of time to score," said Jose Rios, director of student assessment at the Texas Education Agency. In 2023, Rios said TEA hired about 6,000 temporary scorers, but this year, it will need under 2,000. To develop the scoring system, the TEA gathered 3,000 responses that went through two rounds of human scoring. From this field sample, the automated scoring engine learns the characteristics of responses, and it is programmed to assign the same scores a human would have given. This spring, as students complete their tests, the computer will first grade all the constructed responses. Then, a quarter of the responses will be rescored by humans. When the computer has "low confidence" in the score it assigned, those responses will be automatically reassigned to a human. The same thing will happen when the computer encounters a type of response that its programming does not recognize, such as one using lots of slang or words in a language other than English. "In addition to 'low confidence' scores and responses that do not fit in the computer's programming, a random sample of responses will also be automatically handed off to humans to check the computer's work," notes Peters. While similar to ChatGPT, TEA officials have resisted the suggestion that the scoring engine is artificial intelligence. They note that the process doesn't "learn" from the responses and always defers to its original programming set up by the state.
