What kind of bug would make machine learning suddenly 40% worse at NetHack?

One day, a roguelike-playing system just kept biffing it, for celestial reasons.

Members of the Legendary Computer Bugs Tribunal, honored guests, if I may have your attention? I would, humbly, submit a new contender for your esteemed judgment. You may or may not find it novel, you may even deign to call it a "bug," but I assure you, you will find it entertaining.

Consider NetHack. It is one of the all-time roguelike games, and I mean that in the more strict sense of that term. The content is procedurally generated, deaths are permanent, and the only thing you keep from game to game is your skill and knowledge. I do understand that the only thing two roguelike fans can agree on is how wrong the third roguelike fan is in their definition of roguelike, but, please, let us move on.

NetHack is great for machine learning…

Being a difficult game full of consequential choices and random challenges, as well as a "single-agent" game that can be generated and played at lightning speed on modern computers, NetHack is great for those working in machine learning—or imitation learning, actually, as detailed in Jens Tuyls' paper on how compute scaling affects single-agent game learning. Using Tuyls' model of expert NetHack behavior, Bartłomiej Cupiał and Maciej Wołczyk trained a neural network to play and improve itself using reinforcement learning.

New trailer for Alien: Romulus just wants to give us a big, warm face-hug

Beware abandoned space stations “haunted” by xenomorphs.

Director Fede Alvarez promises to bring the sci-fi franchise back to its horror roots with Alien: Romulus.

We got our first look at Alien: Romulus, the ninth installment in the sci-fi franchise, in March with a brief teaser. That footage showed promise that horror director Fede Alvarez (Don't Breathe, Evil Dead) could fulfill his intention to bring this standalone film back to the franchise's stripped-down space horror roots. Now we have the full trailer, and we're pretty confident he's kept that promise. It looks as gory, intense, and delightfully terrifying as the seminal first two films in the franchise.

(Spoilers for Alien and Aliens below.)

As previously reported, Alien: Romulus is set between the events of Alien and Aliens (and is not related to FX/Hulu's Alien prequel series slated to premiere next year). That is, after Ellen Ripley, the sole survivor of the Nostromo, destroyed the killer xenomorph and launched herself into space in the ship's lifeboat—along with the ginger cat, Jonesy—and before she woke up after 57 years in hypersleep and battled more xenomorphs while protecting the young orphan, Newt (Carrie Henn). Per the short-and-sweet official premise: "While scavenging the deep ends of a derelict space station, a group of young space colonizers come face to face with the most terrifying life form in the universe."

GameStop stock influencer Roaring Kitty may lose access to E-Trade, report says

E-Trade fears restricting influencer’s trading may trigger boycott, sources say.

E-Trade is apparently struggling to balance the risks and rewards of allowing Keith Gill to continue trading volatile meme stocks on its platform, The Wall Street Journal reported.

The meme-stock influencer known as "Roaring Kitty" and "DeepF—Value" is considered legendary for instantly skyrocketing the price of stocks, notably GameStop, most recently with a single tweet.

E-Trade is concerned, according to The Journal's insider sources, that on the one hand, Gill's social media posts are potentially illegally manipulating the market—and possibly putting others' investments at risk. But on the other, the platform worries that restricting Gill's trading could incite a boycott fueled by his "meme army" closing their accounts "in solidarity." That could also sharply impact trading on the platform, sources said.

The 2024 Subaru Solterra is nimble but sorely lacks range, personality

Slow charging and inefficient driving, Solterra is no electric WRX or Forester.

Over the years, Subaru has generated a cult following in the US, making its name with all-wheel drive powertrains and a go-anywhere attitude. Cars like the rally-bred WRXes and STIs did a lot of work here, but lately, Subaru has seemed to go in the opposite direction, phasing out fun drives like the STI lineup in favor of volume-movers like the Ascent and bloated versions of existing models such as the Subaru Wilderness editions.

Its first electric vehicle is perhaps even less in character. The $44,995 Solterra is the result of an ongoing partnership with Toyota and was developed together with the bZ4X. Unlike the Toyota, there's no single-motor option for the Solterra. It's all-wheel-drive only, with a pair of identical 107 hp (80 kW) permanent magnet electric motors, one for each axle. That means you can do some, but not all, of the off-road things you'd expect to do with a Subaru.

Looks are deceiving

At first glance, the Solterra looks like the edgy, tech-leaning offspring of a Crosstrek and an Impreza wagon. The 8.3 inches of ground clearance is slightly less than the Outback or Forester, while the Solterra comes in at 184.6 inches (4,689 mm) in length, placing it squarely in the middle of the brand's stable. It's a rather compact SUV, even more so when you try to get comfortable in the cockpit. My short frame was cramped, and anyone taller than me won't feel welcome on long drives.

ISPs seek halt of net neutrality rules before they take effect next month

Fate of net neutrality may hinge on Supreme Court’s “major questions” doctrine.

As expected, broadband industry lobby groups have sued the Federal Communications Commission in an attempt to nullify net neutrality rules that prohibit blocking, throttling, and paid prioritization.

Lobby groups representing cable, telecom, and mobile Internet service providers sued the FCC in several US appeals courts last week. Industry groups also filed a petition with the FCC on Friday asking for a stay of the rules, claiming the regulations shouldn't take effect while litigation is pending because the industry is likely to prevail in court.

The FCC is highly likely to reject the petition for a stay, but the groups can then ask appeals court judges to impose an injunction that would prevent enforcement. The industry lost a similar case during the Obama era, but is hoping to win this time because of the Supreme Court's evolving approach on whether federal agencies can decide "major questions" without explicit instructions from Congress.

Google’s AI Overviews misunderstand why people use Google

Answers that are factually “wrong” are only part of the problem.

Last month, we looked into some of the most incorrect, dangerous, and downright weird answers generated by Google's new AI Overviews feature. Since then, Google has offered a partial apology/explanation for generating those kinds of results and has reportedly rolled back the feature's rollout for at least some types of queries.

But the more I've thought about that rollout, the more I've begun to question the wisdom of Google's AI-powered search results in the first place. Even when the system doesn't give obviously wrong results, condensing search results into a neat, compact, AI-generated summary seems like a fundamental misunderstanding of the way people use Google in the first place.

Reliability and relevance

When people type a question into the Google search bar, they only sometimes want the kind of basic reference information that can be found on a Wikipedia page or corporate website (or even a Google information snippet). Often, they're looking for subjective information where there is no one "right" answer: "What are the best Mexican restaurants in Santa Fe?" or "What should I do with my kids on a rainy day?" or "How can I prevent cheese from sliding off my pizza?"

Windows Recall demands an extraordinary level of trust that Microsoft hasn’t earned

Op-ed: The risks to Recall are way too high for security to be secondary.

Microsoft’s Windows 11 Copilot+ PCs come with quite a few new AI and machine learning-driven features, but the tentpole is Recall. Described by Microsoft as a comprehensive record of everything you do on your PC, the feature is pitched as a way to help users remember where they’ve been and to provide Windows extra contextual information that can help it better understand requests from and meet the needs of individual users.

This, as many users in infosec communities on social media immediately pointed out, sounds like a potential security nightmare. That’s doubly true because Microsoft says that by default, Recall’s screenshots take no pains to redact sensitive information, from usernames and passwords to health care information to NSFW site visits. By default, on a PC with 256GB of storage, Recall can store a couple dozen gigabytes of data across three months of PC usage, a huge amount of personal data.

The line between “potential security nightmare” and “actual security nightmare” is at least partly about the implementation, and Microsoft has been saying things that are at least superficially reassuring. Copilot+ PCs are required to have a fast neural processing unit (NPU) so that processing can be performed locally rather than sending data to the cloud; local snapshots are protected at rest by Windows’ disk encryption technologies, which are generally on by default if you’ve signed into a Microsoft account; neither Microsoft nor other users on the PC are supposed to be able to access any particular user’s Recall snapshots; and users can choose to exclude apps or (in most browsers) individual websites to exclude from Recall’s snapshots.
