Electrical Current Might Be the Key To a Better Cup of Coffee

An anonymous reader quotes a report from Ars Technica: University of Oregon chemist Christopher Hendon loves his coffee -- so much so that studying all the factors that go into creating the perfect cuppa constitutes a significant area of research for him. His latest project: discovering a novel means of measuring the flavor profile of coffee simply by sending an electrical current through a sample beverage. The results appear in a new paper published in the journal Nature Communications.

[...] The coffee industry typically uses a method for measuring the refractive index of coffee -- i.e., how light bends as it travels through the liquid -- to determine strength, but it doesn't capture the contribution of roast color to the overall flavor profile. So for this latest study, Hendon decided to focus on roast color and beverage strength, the two variables most likely to affect the sensory profile of the final cuppa. His solution turned out to be quite simple. Hendon repurposed an electrochemical tool called a potentiostat, typically used to test battery and fuel cell performance. Hendon used the tool to measure how electricity interacted with the liquid. He found that this provided a better measurement of the flavor profile. He even tested it on four different samples of coffee beans and successfully identified the distinctive signature of a batch that had failed the roaster's quality-control process.

Granted, one's taste in coffee is fairly subjective, so Hendon's goal was not to achieve a "perfect" cup but to give baristas a simple tool to consistently reproduce flavor profiles more tailored to a given customer's taste. "It's an objective way to make a statement about what people like in a cup of coffee," said Hendon. "The reason you have an enjoyable cup of coffee is almost certainly that you have selected a coffee of a particular roast color and extracted it to a desired strength. Until now, we haven't been able to separate those variables. Now we can diagnose what gives rise to that delicious cup." Outside of his latest electrical-current experiment, Christopher Hendon's coffee research has shown that espresso can be made more consistently by modeling extraction yield -- how much coffee dissolves into the final drink -- and controlling water flow and pressure.

He also found that static electricity from grinding causes fine coffee particles to clump, which disrupts brewing. The solution: adding a small squirt of water to beans before grinding (known as the Ross droplet technique) to reduce that static, cut clumping and waste, and lead to a stronger, more consistent espresso.

Apple Vision Pro Used In World-First Cataract Surgery

Apple's Vision Pro has been used in what's described as the world's first cataract surgery performed with the headset. MacRumors reports: [New York opthalmologist] Dr. Eric Rosenberg of SightMD completed the initial procedure in October 2025 and has since performed hundreds of additional cases using ScopeXR, a surgical platform he co-developed for Apple's mixed reality device. ScopeXR streams live feeds from 3D digital surgical microscopes directly into the Vision Pro, which lets the surgeon view the operative field in stereoscopic 3D while overlaying preoperative diagnostic data. The platform also supports real-time remote collaboration, allowing surgeons to virtually join procedures and see exactly what the operating surgeon sees. "We are now able to bring the world's best surgeon into any operating room, at any hour, from anywhere on the planet," said Dr. Rosenberg in a company press release. "From residents performing their first cases to surgeons facing unexpected complications, this technology democratizes access to expertise and that will save vision."

Sony Rolls Out 30-Day Online DRM Check-In For PlayStation Digital Games

Sony is reportedly rolling out a 30-day online check-in requirement for some digital PS4 and PS5 games, meaning players could temporarily lose access if their console does not reconnect to renew the license. Tom's Hardware reports: In the info page of an affected game, you'd see a new validity period and a "remaining time" deadline. At first, this seemed like a software bug, but now PlayStation Support has confirmed its authenticity to multiple users. PlayStation owners are furious about the change.

From what we've seen, this DRM is intended for digital game copies. It works by instating a mandatory online check-in where you have to connect to the internet within a rolling 30-day window or risk losing access to the game. Afterward, you can still restore access, but you'll need an internet connection to renew the game's license first. So far, it seems like only games installed after the recent March firmware update are affected.

Affected customers report that setting your PS4 or PS5 as the primary console doesn't alleviate this check-in policy either. No matter what, any game you download from now on will feature this new requirement, effectively eliminating the concept of offline play for even single-player titles.

Apple Introduces a Cheaper Option For App Store Subscriptions

Apple is adding a new App Store subscription option that lets developers offer lower monthly prices in exchange for a 12-month commitment. "This model will allow developers to offer discounted rates to customers in exchange for more predictable long-term revenue," reports TechCrunch. "This also caters to how many developers have already been marketing their annual subscriptions in their apps." From the report: Often, app developers will display the lower monthly price to highlight the discount the customer would receive if they purchase the annual subscription instead of the monthly option. If the user is on the fence about a longer-term commitment, the notion that they're getting a better deal can help to push them toward the annual option.

Now, Apple is essentially formalizing what these developers were already doing, which allows it to also craft a set of policies around how these subscription offers are to be displayed so as not to mislead customers about the true cost of the deals.

However, the option will not be available to developers in the United States or Singapore at launch. While Apple didn't offer an explanation for this, it's still in App Store litigation in the U.S. around the specifics of the court's ruling in its case with Epic Games around how Apple can charge for subscriptions. Apple likely doesn't want to complicate the matter further until that matter is finalized. Singapore, meanwhile, also has a sophisticated payments market with strong consumer rules, which is why it may have been left out of the initial release.

The Bloomberg Terminal Is Getting an AI Makeover

An anonymous reader quotes a report from Wired: For its famous intractability, the Bloomberg Terminal has long inspired devotion, bordering on obsession. Among traders, the ability to chart a path through the software's dizzying scrolls of numbers and text to isolate far-flung information is the mark of a seasoned professional. But as a greater mass of data is fed into the Terminal -- not only earnings and asset prices, but weather forecasts, shipping logs, factory locations, consumer spending patterns, private loans, and so on -- valuable information is being lost. "It has become more and more untenable," says Shawn Edwards, chief technology officer at Bloomberg. "You miss things, or it takes too long."

To try to remedy the problem, Bloomberg is testing a chatbot-style interface for the Terminal, ASKB (pronounced ask-bee), built atop a basket of different language models. The broad idea is to help finance professionals to condense labor-intensive tasks, and make it possible to test abstract investment theses against the data through natural language prompts. As of publication, the ASKB beta is open to roughly a third of the software's 375,000 users; Bloomberg has not specified a date for a full release. Wired spoke with Edwards at Bloomberg's palatial London headquarters in early April, where he shared several examples of what ASKB can do. "With ASKB, I can create workflow templates. I can write a long query, and say, 'Hey, here's all the data I'm going to need. Give me a synopsis of the bull and bear cases, what the Street is saying, what the guidance is.' Now, I want to schedule [the workflows] or trigger them when I see this or that condition in the world."

As for what separates mediocre traders from the best, assuming both have access to the same data, Edwards said: "These tools are not magical. They don't make an average [employee] all of a sudden great. The difference will be your ideas. In the hands of experts, it allows them to do better analysis, deeper research -- to sift through 10 great ideas when they might have only had time for one. If you're a mediocre analyst, they'll be 10 mediocre ideas."

Google and Pentagon Reportedly Agree On Deal For 'Any Lawful' Use of AI

Google has reportedly signed a classified agreement allowing the Pentagon to use its AI models for "any lawful government purpose." While the deal is said to discourage domestic mass surveillance and autonomous weapons without human oversight, it apparently does not give Google the power to block how the government actually uses its models. The Verge reports: The agreement was reported less than a day after Google employees demanded CEO Sundar Pichai block the Pentagon from using its AI amid concerns that it would be used in "inhumane or extremely harmful ways." If the agreement is confirmed, it would place Google alongside OpenAI and xAI, which have also made classified AI deals with the US government. Anthropic was also among that list until it was blacklisted by the Pentagon for refusing the Department of Defense's demands to remove weapon and surveillance-related guardrails from its AI models.

Citing a single anonymous source "with knowledge of the situation," The Information reports that the deal states that both parties have agreed that the search giant's AI systems shouldn't be used for domestic mass surveillance or autonomous weapons "without appropriate human oversight and control." But the contract also says it doesn't give Google "any right to control or veto lawful government operational decision-making," which would suggest the agreed restrictions are more of a pinky promise than legally binding obligations.

(One) Good AI Is Here

The cultural battles over AI have broken down over predictable lines in the past few years, with critics rightfully calling out the big AI platforms for training on content without consent, recklessly building without considering environmental impact, and designing platforms that are unaccountable because their code and weights (the parameters that describe how an AI model works) aren’t open for third-parties to evaluate. The AI zealots have done themselves no favors, by not only dismissing all of these valid criticisms, but by also making increasingly outlandish and extreme claims about the capabilities of the Big AI platforms, while simultaneously scaremongering about the brutal effect they’ll have on people’s lives and careers. It’s no wonder the public sentiment about AI has become so negative.

But a small cohort of us who are curious about LLMs as a technology, yet deeply critical of Big AI companies for their impact on society, have been asking what would “good” AI look like? Is it possible to make versions of these technologies that provide real benefits, and actually help people, without all of the attendant harms? We’ve had prior eras of machine learning tools that were useful technologies without being massively destructive — are the negative externalities intrinsic to LLMs in general?

We might have just gotten our first glimpse at an AI that’s actually good.

This is just one small example that I saw recently, in a very unexpected place, but I can’t get it out of my mind. It’s not a tool that every person in the world is going to use, but it feels a bit like the famous William Gibson quote, “The future is already here — it's just not very evenly distributed.” This might be a little tiny bit of a good AI future, and now we just need to distribute the same kind of thing to a lot more people.

What’s good? Something that checks every box I can think of for our most immediately positive goals: it’s trained entirely with data that were consensually gathered; it’s completely open source and open weights, so anybody can examine it to know exactly how it works and what biases or flaws it might have; it’s designed to run on ordinary computers that normal people have access to — including those that can run entirely on renewable and responsible energy sources. And it is controlled by creators, not extractors, people who are inarguably on the side of artists and creatives and those who make art and culture in the world, designed to support and enable and empower their expression. No billionaires or guests of Epstein’s island were involved in the creation of this technology.

Going Green

Let’s back up a little bit. Corridor Digital is a video production shop and content studio that have been popular on YouTube since the earliest days of its independent filmmaking community. They’ve stayed relevant through many changing trends and format shifts, most recently becoming wildly popular for their ongoing series of video reactions to the visual effects and stunt sequences in popular films and TV shows. Over time, the series has earned a ton of respect from many of the top practitioners in the industry from areas like VFX, stunt work, animation, and more. They even went direct to their fans with a nice subscription service, helping support their work directly.

But still, this was basically a bunch of (mostly) guys making videos. Until something interesting happened recently.

Niko Pueringer, one of the cofounders of Corridor Digital, and one of the more prominent on-screen characters in their filmed content, is not a software developer. Then, a few weeks ago, he decided he had reached a breaking point in one of the challenges that effects artists regularly have to deal with: green screen keying. (That’s the process in which an artist extracts a foreground image from the green background when they’re creating a clip that will be composited together for an effects shot.) Basically, the current tools were crude enough that it felt like an almost manual process, requiring artists to painstakingly cut out images like they were snipping out pictures from a magazine with a dull pair of scissors.

So, Niko created a set of his own videos using CGI to simulate a green screen, and began training an AI model — in this case, a neural network — to learn how to key the footage that he'd generated for this purpose. (He was able to build the tools that carried out this training by asking one of the current popular commercial AI tools to help.) After a good bit of time, trial and error, and heavy computation, the end result was a system that was extremely effective at green screen keying. He even sent an early version of the system to other professionals in the industry to compare its results to their own commercial-grade tools, and they confirmed that it often performed comparably to some of the best tools on the market.

Niko made a video explaining the project — and released the code that would enable others to run the same tool for themselves. (Do check out the clip — the team have become very gifted storytellers, and the narrative does a wonderful job of bringing you along on the journey of the highs and lows of discovering how to try to invent something new.)

Opening up

Once the new tool, now called CorridorKey was out in the wild, a community rapidly formed, and instantly adopted the software into a full-fledged open source project — even though Niko had never led an open source project before. As is typical for such an enthusiast community, they were able to teach their leader about all the arcane processes involved in accepting code improvements from strangers around the world.

Within days, the community had made the tool significantly easier to use — especially for non-expert video editors who would struggle with the complexities of configuring conventional (super-nerdy) open source software. Other community members massively reduced the hardware requirements needed to perform the advanced video processing that the tool enables, moving from needing some of the most powerful workstations available to running on ordinary consumer desktop computers that many home filmmakers might have access to. And all of this for free. Many comparable tools would cost thousands, or even tens of thousands of dollars for video editing teams to use. As Niko said in his original video, he didn’t “want to pay rent for his paintbrush”.

In the follow-up video just two weeks later, it was clear that there had been an extraordinary response to the release of CorridorKey. And an even more extraordinary next milestone was achieved, with the announcement that Niko would be releasing all of the original training data for the creation of the tool — all of the videos and content used to create the model, so that others could replicate the work, or even create their own models if they wanted to improve upon the work itself.

For the technically-minded, CorridorKey is licensed under a modified Creative Commons license, with the intention of preventing commercial exploitation without consent. I’m sure this will prompt some hand-wringing about whether it fits everyone’s definitions of “open source”, but given that someone could certainly reimplement this approach from scratch, given all of the material that Niko and his community have shared, I think that’s a distinction without a difference. The larger point here about a turning point in the AI and LLM ecosystem is what is transformative for creators who’ve been beleaguered by the AI cheerleading for the last few years.

Importantly, using CorridorKey doesn’t impose any restrictions or obligations on people making videos. There’s no phoning home, no scraping of videos to be used for training models, not even collecting an email address for marketing purposes. It’s a stark contrast to what people are used to in the commercial software world, let alone the hyper-surveillance world of most Big AI companies.

Where does this lead?

Okay, so that’s one tool. But what if you’re not a video creator who does things with green screens? How does this help anybody else? There are a few really important breakthroughs here that start to help more people realize what’s possible.

  • The bad behaviors are a choice. The Big AI companies that take content without consent, or who refuse to let people see their code, or who insist they can’t give people control over how their models run and whether they are responsible about their environmental impact can now be definitively refuted. If this small team of creators who aren’t even a tech company can make an AI that does the right thing, how come the biggest companies in the world can’t?
  • It’s about purpose, not one-size-fits-all. There’s no risk that CorridorKey is going to tell kids to self-harm in the way that ChatGPT does. Because CorridorKey has a specific job to do. And that’s the way AI should work — solving a specific problem for a particular community, instead of trying to be all things to all people, which is when these platforms start becoming unaccountable and start harming massive numbers of people.
  • It’s under-hyped, not over-hyped. If anything, the launch of CorridorKey was buried towards the end of a longer video that was about the creative process; the launch video doesn’t even mention the name of the product! The creator doesn’t make any claims about how great it is, or say it’s better than anything else, or say it’s going to change the world. Instead, he’s humble and hopeful that it’s of use to a specific community, and they respond with enthusiasm and connection and collaboration to that sincerity. This isn’t a tool that needs to be shoved in anybody’s face.

All of these traits are things that can be replicated in many more fields, by many more passionate people who don’t have to necessarily be experts, but who care about displacing the tech tycoons’ one-size-fits-all platforms with something that is human-scale and accountable.

For years, I’ve had this conviction that a better AI is possible, and I understand why many people have felt I was being naive, or that the way tech is today makes it impossible for such a thing to survive. But I think the tide is turning, and people are so fed up with the software-brained CEOs forcing things on them that they don’t want. That doesn’t mean that people hate technology! It just means that they hate what these dudes have made technology in to.

It’s nice to be reminded of what tech can be at its best. Sometimes it’s a thing that extracts exactly what we want to see from the background we’re trying to leave behind.

After what felt like a never ending summer with little rain towards the end, all of a sudden, the autumn was upon us. But it just wasn't a sudden drop from unseasonably high temps, we also finally got a bit of wet weather. Not over done, but showers drifting through in what seemed a bit more like Melbourne weather, blue skies one minute then clouds and brief rain, the next.

You can see some of the effect here looking north from Scarborough to the Glasshouse Mountains north of Brisbane. The larger of the two mountains is Mt. Beerburrum, I think!

Goddamn, it's Donut

If you know two things about the Dungeon Crawler Carl book series, one is that it has impressive audiobook adaptations. Listeners are frequently surprised to learn that one man, Jeff Hays, is responsible for all the voices (aside from a couple guest spots.) The eighth book in the series, A Parade of Horribles, is due in a couple weeks, but you can get a peek behind the curtain and watch Hays record the first few chapters of the audiobook (spoilers, obv.)

While the audiobooks proper are under a ten year exclusive contract with Audible, Hays' production company, Soundbooth Theater, has been recording an audio drama version—dubbed an "Audio Immersion Tunnel"—that they distribute themselves. These are slightly re-worked versions with author Matt Dinniman's input and/or approval, added sound effects, music, and an expanded cast (Hays still voices the main characters.) You can watch him recording Season One, Episode One (Part 2, Part 3.) The finished episode is free on Soundbooth's app.

King Charles III addresses a joint session of Congress

AP report King Charles III addressed a joint session of the U.S. Congress today, only the second British monarch to do so after Queen Elizabeth II in 1991. Speaking during the 250th year of American independence, he invoked Magna Carta, Oscar Wilde's line about being "divided by a common language," and framed the relationship as "A Tale of Two Georges" — Washington and George III. An interesting blend of speechwriting, symbolism, diplomacy, and royal theatre. Curious what others made of the speech.
