I have a theory about electric vehicles, and with a few notable exceptions, it's this: The cheaper, less powerful version is usually the one to get. Big power outputs and short 0–60 times have been the industry's go-to, but always with the trade-off being less range and a bigger sticker price. Today's EV is a good example. It's the BMW i4 eDrive40, a single-motor version of BMW's smaller electric fastback sedan. It has taken a while to get some seat time in one, but the wait was worth it, because this is one of the best electric sedans we've tested so far.

I've driven the BMW i4 a few times now since its launch in 2021, but always the very fast, very powerful, rather expensive i4 M50. Which is fine, but not exciting like the M3. The i4 eDrive40 undercuts the twin-motor, all-wheel drive M50 by more than $10,000—it starts at a more reasonable $57,300 and goes more than 30 miles (48 km) farther on a single charge of the same capacity 84.3 kWh (net) battery pack, with an EPA range of 301 miles (484 km).

BMW made its name on the back of a string of driver-focused, rear-wheel drive sedans, and I had high expectations for the eDrive40 to live up to. With no front motor, there's less weight on the front axle, and the front wheels just have to worry about steering and braking, not laying down power as well. Less power to put down means smaller wheels, which translates into a better ride and more range, although our test car was equipped with 19-inch wheels (a $600 option), which reduced its range to 283 miles (455 km) compared to the 18-inch option.

For more than four days, a server at the very core of the Internet’s domain name system was out of sync with its 12 root server peers due to an unexplained glitch that could have caused stability and security problems worldwide. This server, maintained by Internet carrier Cogent Communications, is one of the 13 root servers that provision the Internet’s root zone, which sits at the top of the hierarchical distributed database known as the domain name system, or DNS.

Here's a simplified recap of the way the domain name system works and how root servers fit in:

When someone enters wikipedia.org in their browser, the servers handling the request first must translate the human-friendly domain name into an IP address. This is where the domain name system comes in. The first step in the DNS process is the browser queries the local stub resolver in the local operating system. The stub resolver forwards the query to a recursive resolver, which may be provided by the user's ISP or a service such as 1.1.1.1 or 8.8.8.8 from Cloudflare and Google, respectively.

CAMBRIDGE, Massachusetts—On Wednesday, AI enthusiasts and experts gathered to hear a series of presentations about the state of AI at EmTech Digital 2024 on the Massachusetts Institute of Technology's campus. The event was hosted by the publication MIT Technology Review. The overall consensus is that generative AI is still in its very early stages—with policy, regulations, and social norms still being established—and its growth is likely to continue into the future.

I was there to check the event out. MIT is the birthplace of many tech innovations—including the first action-oriented computer video game—among others, so it felt fitting to hear talks about the latest tech craze in the same building that hosts MIT's Media Lab on its sprawling and lush campus.

EmTech's speakers included AI researchers, policy experts, critics, and company spokespeople. A corporate feel pervaded the event due to strategic sponsorships, but it was handled in a low-key way that matches the level-headed tech coverage coming out of MIT Technology Review. After each presentation, MIT Technology Review staff—such as Editor-in-Chief Mat Honan and Senior Reporter Melissa Heikkilä—did a brief sit-down interview with the speaker, pushing back on some points and emphasizing others. Then the speaker took a few audience questions if time allowed.

The US government today sued Live Nation and its Ticketmaster subsidiary in a complaint that seeks a breakup of the company that dominates the live music and events market.

The US Department of Justice is seeking "structural relief," including a breakup, "to stop the anticompetitive conduct arising from Live Nation's monopoly power." The DOJ complaint asked a federal court to "order the divestiture of, at minimum, Ticketmaster, along with any additional relief as needed to cure any anticompetitive harm."

The District of Columbia and 29 states joined the DOJ in the lawsuit filed in US District Court for the Southern District of New York. "One monopolist serves as the gatekeeper for the delivery of nearly all live music in America today: Live Nation, including its wholly owned subsidiary Ticketmaster," the complaint said.

The latest addition to Chevrolet's growing family of Ultium electric vehicles recently began shipping to dealers in the form of the Silverado EV's early RST First Edition package. Silverado's top spec level now joins the lineup's previous fleet-only WT trim, meaning the general public can now purchase an enormous electric pickup that strongly resembles the Avalanche of 2001 to 2013. But despite any other similarities to the Hummer EV, which shares a related chassis, or ICE trucks of old, the 2024 Silverado aims to change the game for GM's market positioning despite arriving a full 24 months after Ford's F-150 Lightning.

With a large crew cab, a longer truck bed, and angular sail panels, the Silverado EV looks less boxy than GMC's Hummer EV. Aero gains thanks to the smoother design pair with lower rolling-resistance tires, allowing the Silverado to achieve an EPA range estimate of up to 450 miles (724 km), though the RST First Edition I recently drove over the course of a long day in Michigan earns a rating of 440 miles (708 km).

On the highway, judging by wind noise around the cabin alone, the aerodynamic gains of the Silverado's styling seem to make a noticeable difference versus the Hummer. On the other hand, tire hum might cover up any aero deficiencies because the RST's single weirdest detail constantly occupies center stage here: a set of 24-inch wheels, the largest ever equipped to a car, truck, or SUV straight from the factory.
