Month: March 2023

Nearly a year after Elon Musk first floated the idea of making Twitter’s recommendation algorithm public, the company has posted the source code for its recommendation algorithm on GitHub. In a Twitter Space discussing the move, Musk said he hoped users would be able to find potential “issues” in the code and help make it better.
“Our initial release of the so-called algorithm is going to be quite embarrassing and people are gonna find a lot of mistakes but we’re going to fix them very quickly,” Musk said.
Notably, the code released Friday only deals with how tweets are shown in Twitter’s “For You” feed. The company didn’t release the underlying code for its search algorithm or how content is displayed on other parts of Twitter, though Musk said the company would “for sure” open-source the search algorithm as well.
In a blog post outlining how Twitter’s recommendations work, the company explained the various steps of the algorithm, including ranking and filtering. But Twitter users have already been finding interesting details in the code itself. For example, Jane Manchun Wong noted that “Twitter’s algorithm specifically labels whether the Tweet author is Elon Musk.” That may offer yet another explanation for why Musk’s tweets appear so often. Wong also noted that the algorithm has labels indicating whether the tweet author is a “power user” as well as whether they are a Republican or Democrat.

When asked about that aspect of the algorithm in the Twitter Space, Musk said “I agree that shouldn’t be there … it definitely shouldn’t be dividing people into Republicans and Democrats, that makes no sense.” A Twitter engineer later followed up to clarify that the categories were only for “stat tracking purposes and it has nothing to do with the algorithm.” He said the labels are meant “to make sure we don’t bias towards one group versus another one” though he didn’t address why Musk had his own category.
“But isn’t it weird that you have four categories and one of them is Elon,” the questioner responded. “I think it’s weird,” Musk said. “This was the first time I’m learning this.” The Twitter engineer didn’t directly respond with an explanation. The Twitter Space ended less than a minute later. This article originally appeared on Engadget at https://www.engadget.com/twitters-recommendation-algorithm-is-now-on-github-200511112.html?src=rss

California will require more than half of all heavy trucks sold in the state to be electric by 2035. The rule received approval from the Biden administration today, allowing it to take effect next year, according toThe New York Times. California approved the mandate in 2020 but needed an Environmental Protection Agency (EPA) waiver because it exceeded federal standards.
The rule aims to reduce greenhouse gas emissions from the transportation sector. By 2035, it requires 55 percent of delivery vans and small trucks sold in California to be entirely electric-powered. Similarly, 40 percent of tractor-trailers and 75 percent of buses and larger trucks must be all-electric by the same deadline.
California Governor Gavin Newsom sees the mandate as a bellwether for the nation. “This is a moment to mark because it’s a preview of the order of magnitude of the change in the industry,” Newsom told The New York Times. “There’s a power in these waivers and that power is emulation. We adopt through these waivers the principles and policies that lead to innovation and investment.” Given the size and centrality of California’s economy (it would be the world’s fifth-biggest economy if it were a sovereign nation), the rule would, in practice, essentially apply nationwide — similar to the state’s ban on sales of gas-powered vehicles by 2035.
The trucking industry has criticized the move for its costs and infrastructure requirements. “Drivers don’t want to work in California anymore,” said Jay Grimes, director of federal affairs for the Owner-Operator Independent Drivers Association. “They’re skeptical of the rapid timeline on this transition to electric trucks. Can a trucker get a charge that will take them on a highway for two or three days? Is the technology ready for prime time?” He adds that batteries for electric trucks can weigh thousands of pounds more than combustion engines, potentially limiting hauls. Other truckers have questioned whether the charging station rollout will be adequate for long trips. Finally, electric trucks are more expensive, starting at around $100,000 and stretching into high six figures (although the pricing discrepancies compared to gas trucks could drop over time).
Unsurprisingly, attorneys general from 17 Republican-led states are suing to block the legislation. That list includes (among others) Texas AG Ken Paxton, who has received over $3.9 million in fossil fuel donations since 2002, and Louisiana AG Jeff Landry, who has raked in over $875,000 from oil and gas industries. Their lawsuit is scheduled for the US Court of Appeals for Washington, DC, later this year and could move to the conservative-dominated US Supreme Court afterward.
Clean energy groups acknowledge the mandate’s difficulties but strike an optimistic tone. “There’s a great deal of challenge with the electrification of heavy-duty vehicles,” said Drew Kodjak, executive director of the International Council on Clean Transportation. “But there are elements that lead to optimism.” For example, he points out that government tax incentives and savings from not having to buy gasoline will help with long-term costs. “Companies like FedEx look at the bottom line over the total life span of a vehicle. And when they look long-term, the calculations for this become more optimistic.”This article originally appeared on Engadget at https://www.engadget.com/california-will-require-half-of-heavy-truck-sales-to-be-electric-by-2035-200313559.html?src=rss
