Interesting research: “Guillotine: Hypervisors for Isolating Malicious AIs.”

Abstract:As AI models become more embedded in critical sectors like finance, healthcare, and the military, their inscrutable behavior poses ever-greater risks to society. To mitigate this risk, we propose Guillotine, a hypervisor architecture for sandboxing powerful AI models—models that, by accident or malice, can generate existential threats to humanity. Although Guillotine borrows some well-known virtualization techniques, Guillotine must also introduce fundamentally new isolation mechanisms to handle the unique threat model posed by existential-risk AIs. For example, a rogue AI may try to introspect upon hypervisor software or the underlying hardware substrate to enable later subversion of that control plane; thus, a Guillotine hypervisor requires careful co-design of the hypervisor software and the CPUs, RAM, NIC, and storage devices that support the hypervisor software, to thwart side channel leakage and more generally eliminate mechanisms for AI to exploit reflection-based vulnerabilities. Beyond such isolation at the software, network, and microarchitectural layers, a Guillotine hypervisor must also provide physical fail-safes more commonly associated with nuclear power plants, avionic platforms, and other types of mission critical systems. Physical fail-safes, e.g., involving electromechanical disconnection of network cables, or the flooding of a datacenter which holds a rogue AI, provide defense in depth if software, network, and microarchitectural isolation is compromised and a rogue AI must be temporarily shut down or permanently destroyed.

The basic idea is that many of the AI safety policies proposed by the AI community lack robust technical enforcement mechanisms. The worry is that, as models get smarter, they will be able to avoid those safety policies. The paper proposes a set technical enforcement mechanisms that could work against these malicious AIs.

Kalley Huang and Erin Woo, reporting for The Information (via Ed Zitron, who summarized it on Bluesky):

Meta Platforms over the past year asked Microsoft, Amazon and others to help pay the costs of training Meta’s flagship large language model, Llama, according to four people briefed on the discussions. Meta’s overtures reflected worries about the growing costs of its artificial intelligence development, according to two of the people. [...]

Meta in particular has faced questions about the business logic behind its AI development, given that Llama is open-source software, freely available for anyone’s use. That makes it difficult to turn into a business. And Meta makes money primarily from advertising and has little experience in selling business software.

While Meta held its most serious discussions with Amazon and Microsoft, it has also discussed the idea with Databricks, IBM and Oracle, as well as representatives from at least one Middle Eastern investor, according to two of the people briefed on the discussions. Meta was still in discussions with companies about the Llama Consortium as recently as the start of this year, the two people said.

Would you consider throwing a few sacks full of your cash on this bonfire of our cash that we’ve been burning?” is a hell of a pitch.

In its discussions with other companies, Meta primarily asked for money. It also sought servers or other resources that would offset the cost of training its models, according to two of the people briefed on the discussions. In return for their assistance, Meta discussed offering other companies promotion of their services alongside Llama — for example, a Meta executive might appear at a conference hosted by a consortium partner — or providing more insight into the training process for the model, one of those people said.

Pay a little and a Meta representative will show up at your developer conference. Pay more and a Meta rep won’t show up at your developer conference.

Larry David: ‘My Dinner With Adolf’

Larry David, in a column for The New York Times:

He loved that story, especially the part where Hitler shot the dog before it got back into the car. Then a beaming Hitler said, “Hey, if I can kill Jews, Gypsies and homosexuals, I can certainly kill a dog!” That perhaps got the biggest laugh of the night — and believe me, there were plenty.

I have been reliably informed that, having linked approvingly to Bill Maher’s “book report” on his dinner with Trump, I must also link to David’s report of dinner with Adolf.

Radek Sienkiewicz:

If you pay attention to AI company branding, you’ll notice a pattern:

  1. Circular shape (often with a gradient)
  2. Central opening or focal point
  3. Radiating elements from the center
  4. Soft, organic curves

Sound familiar? It should, because it’s also an apt description of ... well, you know.

A butthole.

Jeff Stein, Elizabeth Dwoskin, and Cat Zakrzewski, reporting for The Washington Post:

As President Donald Trump’s enormous new tariffs on China rippled through global supply chains, Apple CEO Tim Cook went to work behind the scenes.

Cook spoke to Commerce Secretary Howard Lutnick last week about the potential impact of the tariffs on iPhone prices, two people familiar with the phone call said, speaking on the condition of anonymity to reflect private conversations that were previously unreported. Cook spoke with other senior officials in the White House, the people said. And he refrained from publicly criticizing the president or his policies on national television, as many other executives have over the past several weeks.

By the end of the week, the Trump administration agreed to exempt from import duties electronic products that Apple produces in China, an action that also granted a reprieve to other large U.S. firms, including HP and Dell. Trump did so despite the recommendations of senior White House aide Peter Navarro, who had wanted the taxes to remain in place, the people said.

Three points:

  1. Tim Cook manages this dance with aplomb. This is not a “good system”. But given the way Trump operates, what Cook managed here is not merely good for Apple but better policy, period.

  2. Howard Lutnick is a lickspittle moron with the demeanor of a used car salesman who knowingly sells overpriced lemons to suckers. Here he is on Meet the Press a few weeks ago bragging that “The army of millions and millions of human beings screwing in little screws to make iPhones — that kind of thing is going to come to America.” Keith Olbermann mentioned in a recent episode of his podcast that Lutnick is a dead ringer for Morrie Kessler, the bookmaker of “Morrie’s Wigs” fame from Goodfellas, and I can’t un-see it.

  3. Peter Navarro is such a profound dope and abject fraud — seriously, he’s not even good at making up phony names — that he makes Lutnick seem like a credible, responsible official.

Dekáf Coffee Roasters

My thanks to Dekáf Coffee Roasters for sponsoring last week at DF. Dekáf started with a simple question over a late-night cup of decaf: why do coffee lovers who skip the caffeine have to skip the craft too?

Dekáf believes those who drink coffee purely for its flavor are the true connoisseurs. While other roasters treat decaf as a side project, they’ve made it their entire mission. They’re dedicated to creating exceptional decaffeinated coffee that stands toe-to-toe with the world’s finest caffeinated beans.

I drink coffee every single day. I literally can’t remember the last day I didn’t have coffee in the morning. A few years ago, though, age started catching up to me and I stopped drinking coffee after lunch or so, lest it screw with my sleep. I really missed my afternoon coffee though. Why I didn’t think to try decaf I don’t know, but Dekáf sent me a few samples earlier this month and it’s been a revelation. In addition to fully decaffeinated roasts, they also have some half-decaffeinated roasts, and they’re absolutely delicious — my style of roast, for sure — and they don’t leave me jolted into the evening. Maybe you like tea, but I don’t. I like coffee, and I love being able to have a cup or two late in the afternoon again. It’s so good.

Also, I’m a big believer that you can judge a book by its cover. Just look at the Dekáf brand. It’s perfect. Color, typography, artwork — so cool, so spot-on for what they do.

Dekáf offers 9 single origins, and 6 signature blends. You won’t believe it’s decaf. That’s the point. Even better, get 30% off with code: DF.

A Few DF Sponsorship Openings

Weekly sponsorships have been the top source of revenue for Daring Fireball ever since I started selling them back in 2007. They’ve succeeded, I think, because they make everyone happy. They generate good money. There’s only one sponsor per week and the sponsors are always relevant to at least some sizable portion of the DF audience, so you, the reader, are never annoyed and hopefully often intrigued by them. And, from the sponsors’ perspective, they work. My favorite thing about them is how many sponsors return for subsequent weeks after seeing the results.

I’ve got three openings left through the end of June:

  • April 21–27 (next week)
  • May 12–18
  • May 26–June 1

If you’ve got a product or service you think would be of interest to DF’s audience of people obsessed with high quality and good design, get in touch.

CNN:

A federal appeals court rejected the Trump administration’s request that it halt the next steps Judge Paula Xinis is seeking to take in the case concerning a migrant who was wrongly deported to El Salvador, with a strident warning about the rule of law and the possibility the dispute presented an “incipient crisis.”

The 4th US Circuit Court of Appeals said in its seven-page ruling Thursday that the Trump administration’s assertions in the case “should be shocking not only to judges, but to the intuitive sense of liberty that Americans far removed from courthouses still hold dear.”

The unanimous ruling was written by Judge Harvie Wilkinson, an appointee of former President Ronald Reagan. In it, he was extremely critical of the administration’s effort to undo some of Xinis’ recent orders in the case, sounding alarm bells about how its maneuverings in the matter have resulted in the two branches “grinding irrevocably against one another in a conflict that promises to diminish both.”

Quoting from Wilkinson’s order:

It is difficult in some cases to get to the very heart of the matter. But in this case, it is not hard at all. The government is asserting a right to stash away residents of this country in foreign prisons without the semblance of due process that is the foundation of our constitutional order. Further, it claims in essence that because it has rid itself of custody that there is nothing that can be done.

This should be shocking not only to judges, but to the intuitive sense of liberty that Americans far removed from courthouses still hold dear.

The government asserts that Abrego Garcia is a terrorist and a member of MS-13. Perhaps, but perhaps not. Regardless, he is still entitled to due process. If the government is confident of its position, it should be assured that position will prevail in proceedings to terminate the withholding of removal order.

No minced words. No equivocation. No histrionics either. Just calling it like it is. More like this, please. This needs to be faced head-on, with plain language.

Kim Mackrael and Sam Schechner, reporting for The Wall Street Journal (News+ link):

The European Commission, the EU’s executive body, had initially planned to announce cease-and-desist orders targeting the tech giants on Tuesday and had informed at least one of the companies of that timing, people familiar with the matter said. Both companies could have also been slapped with fines.

The decision to postpone the announcement was made shortly before EU Trade Commissioner Maroš Šefčovič met with U.S. officials in Washington on Monday, for his first in-person talks since President Trump announced a 90-day pause on some tariffs. In addition, this week Italian Prime Minister Giorgia Meloni met with Trump, who said he would have “very little problem” making a trade deal with the EU.

The rulings are still expected to go ahead, and it isn’t immediately clear how long the delay might last.

Pretty much what I thought happened to these fines.

The best new products are light, ungreasy – and leave no white cast

I never thought I’d write so uncritically about a mineral sunscreen, but what follows is an unequivocal rave. Sunscreens that use zinc oxide or titanium dioxide (rather than synthetic chemical filters) can be useful, even essential, for those with highly sensitive and reactive skin. They tend not to cause the stinging or streaming eyes common with synthetics, and some studies show they’re a more helpful option for those with melasma and other pigmentation issues. They also play well with makeup, while some synthetics can ball up and peel off when applying foundation.

But all this goodness comes with a short but significant cons list: minerals are heavier, greasier and leave a trace, ranging from a fine, chalky veil to a ghostly white cast. It isn’t pleasant for anyone, but is particularly intolerable on deeper skin tones.

Age Verification Using Facial Scans

Discord is testing the feature:

“We’re currently running tests in select regions to age-gate access to certain spaces or user settings,” a spokesperson for Discord said in a statement. “The information shared to power the age verification method is only used for the one-time age verification process and is not stored by Discord or our vendor. For Face Scan, the solution our vendor uses operates on-device, which means there is no collection of any biometric information when you scan your face. For ID verification, the scan of your ID is deleted upon verification.”

I look forward to all the videos of people hacking this system using various disguises.

Spending More to Get Less Is Good?

Brian X. Chen, in a column at The New York Times headlined “Why a Tariff-Inflated $2,000 iPhone Is Nothing to Fear”:

Don’t panic. Even if tariffs did cause the iPhone’s price to surge, we would have plenty of cheaper options, like buying last year’s phone model instead of the latest and greatest.

The most important lesson we can learn from the turmoil: The only consistent way to save money on tech is to use devices for as long as possible, which requires maintaining them as you would a car, and upgrading only when you must.

This whole angle is no surprise coming from the tech columnist whose advice to readers who think their aging phone cameras don’t perform well in low light is “Just use flash.” If phone prices go up because of Trump’s tariffs, all phone prices are going to go up, including those for older models, whether you’re buying new or used. There is no silver lining here. Spending more to get a years-old phone sucks too.

Take the iPhone 16 as an example. Its $800 price tag can easily inflate to $1,080, since you may also buy:

  • An iPhone case for $50
  • AirPods for $130
  • 256 gigabytes of storage for $100

So if you buy things that aren’t an iPhone — like AirPods — the price of an iPhone goes up. Got it.

The anti-“big tech” bias here is so obvious. Don’t hold your breath waiting for a similar article in the Times about how it’s no big deal, nothing to worry about, if the price of cars doubles under these tariffs.
