Nvidia and AMD both plan to launch more affordable GPUs in February and March

Will the GeForce RTX 5070 and Radeon RX 9070 achieve the dream of affordable 4K?

The GeForce RTX 5090 and 5080 are both very fast graphics cards—if you can look past the possibility that we may have yet another power-connector-related overheating problem on our hands. But the vast majority of people (including you, discerning and tech-savvy Ars Technica reader) won't be spending $1,000 or $2,000 (or $2,750 or whatever) on a new graphics card this generation.

No, statistically, you (like most people) will probably end up buying one of the more affordable midrange Nvidia or AMD cards, GPUs that are all slated to begin shipping later this month or early in March.

There has been a spate of announcements on that front this week. Nvidia announced yesterday that the GeForce RTX 5070 Ti, which the company previously introduced at CES, would be available starting on February 20th for $749 and up. The new GPU, like the RTX 5080, looks like a relatively modest upgrade from last year's RTX 4070 Ti Super. But it ought to at least flirt with affordability for people who are looking to get natively rendered 4K without automatically needing to enable DLSS upscaling to get playable frame rates.

AI used to design a multi-step enzyme that can digest some plastics

Enzyme mechanisms can be complex, and getting them to work is tricky.

Enzymes are amazing catalysts. These proteins are made of nothing more than a handful of Earth-abundant elements, and they promote a vast array of reactions, convert chemical energy to physical motion, and act with remarkable specificity. In many cases, we have struggled to find non-enzymatic catalysts that can drive some of the same chemical reactions.

Unfortunately, there isn't an enzyme for many reactions we would sorely like to catalyze—things like digesting plastics or incorporating carbon dioxide into more complex molecules. We've had a few successes using directed evolution to create useful variations of existing enzymes, but efforts to broaden the scope of what enzymes can do have been limited.

With the advent of AI-driven protein design, however, we can now potentially design things that are unlike anything found in nature. A new paper today describes a success in making a brand-new enzyme with the potential to digest plastics. But it also shows how even a simple enzyme may have an extremely complex mechanism—and one that's hard to tackle, even with the latest AI tools.

DOGE’s .gov site lampooned as coders quickly realize it can be edited by anyone

DOGE site is apparently not running on government servers.

"An official website of the United States government," reads small text atop the Department of Government Efficiency (DOGE) website that Elon Musk's team started populating this week with information on agency cuts.

But you apparently don't have to work in government to push updates to the site. A couple of prankster web developers told 404 Media that they separately discovered how "insecure" the DOGE site was, seemingly pulling from a "database that can be edited by anyone."

One coder couldn't resist and pushed two updates that, as of this writing, remained on the DOGE site. "This is a joke of a .gov site," one read. "THESE 'EXPERTS' LEFT THEIR DATABASE OPEN," read another.

Reddit plans to lock some content behind a paywall this year, CEO says

How will Reddit generate content for paid-for subreddits?

Reddit is planning to introduce a paywall this year, CEO Steve Huffman said during a videotaped Ask Me Anything (AMA) session on Thursday.

Huffman previously showed interest in potentially introducing a new type of subreddit with "exclusive content or private areas" that Reddit users would pay to access.

When asked this week about plans for some Redditors to create "content that only paid members can see," Huffman said:

After 20% range reduction, I’m waiting for Jaguar to buy my car back

Every MY2019 Jaguar I-Pace in the US is being bought back due to a battery defect.

In November 2019, I was overjoyed to drive a new Jaguar I-Pace off the dealer's lot. Five years later, I'm waiting for Jaguar to drive the car away.

After two recalls for software updates, the car's range is now permanently restricted to 80 percent of what it was new. And along with owners of over 2,700 2019 I-Paces, I'm waiting for Jaguar to buy the car back. That's because the company has decided that purchasing the cars is cheaper—and likely easier—than identifying and replacing defective battery packs. It's a frustrating situation to be in, and not just because I can no longer drive a car I have grown to like.

Why did I buy an I-Pace? Good question—after all, Jaguars are not renowned for being paragons of reliability. 2019 was also the first year for the I-Pace, and buying a car in its first model can be a risky move as unanticipated manufacturing and parts problems rear their heads. One example: The original wiring harness in the I-Pace was poorly designed, so Jaguar ended up replacing many of them (including mine), which the mechanic told me took 11 hours and involved disassembling the front of the car.
