Starting today, Warner Bros. Games is taking the formal veil off its worst-kept video game secret in years: Multiversus. When we saw the leaks about this upcoming free-to-play PC and console game, which stars various WB and Time Warner intellectual property in a cartoony, Smash Bros.-style arena fighter, we had our reservations. Was WB seriously trying to compete with Nintendo's biggest fighting game by pitting Arya Stark against... Shaggy from Scooby-Doo? Whose dream cartoon face-off is that?

A few days ago, WB invited us to go hands-on to see for ourselves what the game is like ahead of today's launch of a closed alpha test to address those kinds of questions and more. So far, we've come away impressed and surprised. In a world that didn't necessarily need another Smash Bros. clone, the devs at Player First Games have seemingly cracked the code—and made something that could neatly coexist with Nintendo's massive hit, if not surpass it. (Even better, at first blush, the F2P stuff seems tolerable!)

Most of the "arena fighter" genre basics, as established by Smash Bros., are accounted for in WB's latest fighting game. Instead of wearing down an energy bar à la Street Fighter, Multiversus players try to "ring out" their foes by racking up damage and setting up knockout blows. Movement is pretty Super Mario-like in terms of dashing and jumping between floating platforms, and players have a range of basic and special attacks that don't require complex joystick and button combos.

Since the financial crisis, corporate lawyers have aspired to build the ultimate ironclad merger contract that keeps buyers with cold feet from backing out.

The “bulletproof” modern deal agreement now faces one of its biggest tests, as Elon Musk, the Tesla boss and richest person in the world, openly entertains the possibility of ditching his $44 billion deal for Twitter.

Musk said in a tweet this week that the “deal cannot move forward” until the social media platform provides detailed data about fake accounts, a request that Twitter seems unlikely to meet. Twitter’s board, meanwhile, has stated its commitment “to completing the transaction on the agreed price and terms as promptly as practicable."

Amazon has updated the 7-inch Fire Tablet—it's now the "2022, 12th gen" version. The big news this year is that Amazon is finally upgrading to USB-C, which is tough to come by in this bargain-basement pricing tier. About that price: The Fire 7 is $74.99 without lockscreen ads or $59.99 if you want to put up with the ads.

For the SoC, we have a MediaTek MT8168V. This is a 12 nm chip with four ARM Cortex A53 cores running at 2 GHz and an ARM Mali G52. There's a 7-inch, 1024×600 LCD, 2GB of RAM, 16GB of storage (or $20 more for 32GB), and a "10-hour" battery. (We'll update this article if Amazon gets back to us about the battery size.) There's a microSD slot, a headphone jack, and Wi-Fi 5 (that's 802.11ac) support. There are technically front and back cameras on the Fire 7, but at 2 MP each and "no autofocus," they might not be useful for much. There's no GPS and no NFC, but the tablet comes with a 5 W USB-C charger.

The 2022 Fire 7 also marks the launch of Amazon's "Fire OS 8." This is a fork of Android 11 that doesn't seem to stray far from the normal codebase, but it doesn't have any Google apps or services. Amazon is promising four years of security updates, even at this ultra-low price point.

One of the best things about electric cars, other than their power trains, immediate torque, and relaxing quiet, is the fact that as the electrical grid becomes cleaner, so too does every EV that uses that grid to charge. That process took a step forward this week with the news that by next year, the Electrify America (EA) charging network will be entirely offset by solar energy.

On Wednesday, EA signed a 15-year agreement with Terra-Gen to purchase electricity from a 75 MW solar farm being built by the latter in San Bernardino County, California. In the past, Tesla CEO Elon Musk has made various promises about making Tesla’s Supercharger network entirely solar-powered, and the automaker has installed solar arrays at some of its charging locations. It does not appear that the network is fully solar-powered yet, though.

The Electrify America Solar Glow 1 project will break ground later this year, and when it's fully operational in 2023, it should have an annual energy production of 225,000 MWh. That’s more than enough to account for the annual energy use of the EA charging network.

Dr. Sephus discusses breaking down barriers to machine learning at Ars Frontiers 2022. Click here for transcript. (video link)

Welcome to the week after Ars Frontiers! This article is the first in a short series of pieces that will recap each of the day's talks for the benefit of those who weren't able to travel to DC for our first conference. We'll be running one of these every few days for the next couple of weeks, and each one will include an embedded video of the talk (along with a transcript).

For today's recap, we're going over our talk with Amazon Web Services tech evangelist Dr. Nashlie Sephus. Our discussion was titled "Breaking Barriers to Machine Learning."
