The Wyden Siren Goes Off Again: We’ll Be “Stunned” By What the NSA Is Doing Under Section 702

Published

on

from the it’s-blaring dept

Senator Ron Wyden says that when a secret interpretation of Section 702 is eventually declassified, the American public “will be stunned” to learn what the NSA has been doing. If you’ve followed Wyden’s career, you know this is not a man prone to hyperbole — and you know his track record on these warnings is perfect.

Just last month, we wrote about the Wyden Siren — the pattern where Senator Ron Wyden sends a cryptic public signal that something terrible is happening behind the classification curtain, can’t say what it is, and then is eventually proven right. Every single time. The catalyst then was a two-sentence letter to CIA Director Ratcliffe expressing “deep concerns about CIA activities.”

Well, the siren is going off once again. This time, Wyden took to the Senate floor to deliver a lengthy speech, ostensibly about the since approved (with support of many Democrats) nomination of Joshua Rudd to lead the NSA. Wyden was protesting that nomination, but in the context of Rudd being unwilling to agree to basic constitutional limitations on NSA surveillance. But that’s just a jumping off point ahead of Section 702’s upcoming reauthorization deadline. Buried in the speech is a passage that should set off every alarm bell:

There’s another example of secret law related to Section 702, one that directly affects the privacy rights of Americans. For years, I have asked various administrations to declassify this matter. Thus far they have all refused, although I am still waiting for a response from DNI Gabbard. I strongly believe that this matter can and should be declassified and that Congress needs to debate it openly before Section 702 is reauthorized. In fact, when it is eventually declassified, the American people will be stunned that it took so long and that Congress has been debating this authority with insufficient information.

You can see the full video here if you want.

Here’s a sitting member of the Senate Intelligence Committee — someone with access to the classified details — is telling his colleagues and the public that there is a secret interpretation of Section 702 that “directly affects the privacy rights of Americans,” that he’s been asking multiple administrations to declassify it, that they’ve all refused, and that when it finally comes out, people will be stunned.

If you’ve followed Wyden for any amount of time, this all sounds very familiar. In 2011, Wyden warned that the government had secretly reinterpreted the PATRIOT Act to mean something entirely different from what Congress and the public understood. He couldn’t say what. Nobody believed it could be that bad. Then the Snowden revelations showed the NSA was engaged in bulk collection of essentially every American’s phone metadata. In 2017, he caught the Director of National Intelligence answering a different question than the one Wyden asked about Section 702 surveillance. The pattern repeats. The siren sounds. Years pass. And then, eventually, we find out it was worse than we imagined.

Now here he is, doing the exact same thing with Section 702 yet again, now that it’s up for renewal. Congress is weeks away from a reauthorization vote, and Wyden is explicitly telling his colleagues (not for the first time) they are preparing to vote on a law whose actual meaning is being kept secret from them as well as from the American public:

The past fifteen years have shown that, unless the Congress can have an open debate about surveillance authorities, the laws that are passed cannot be assumed to have the support of the American people. And that is fundamentally undemocratic. And, right now, the government is relying on secret law with regard to Section 702 of FISA. I’ve already mentioned the provision that was stuck into the last reauthorization bill, that could allow the government to force all sorts of people to spy on their fellow citizens. I have explained the details of how the Biden Administration chose to interpret it, and how the Trump Administration will interpret it, are a big secret. Americans have the right to be confused and angry that this is how the government and Congress choose to do business.

That’s a United States senator who has a long history of calling out secret interpretations that lead to surveillance of Americans — standing on the Senate floor and warning, once again, that there’s a secret interpretation of Section 702 authorities. One that almost certainly means mass surveillance.

And Wyden knows exactly how this plays out. He’s been through the reauthorization cycle enough times to know the playbook the intelligence community runs every time 702 is up for renewal:

I’ve been doing this a long time, so I know how this always goes. Opponents of reforming Section 702 don’t want a real debate where Members can decide for themselves which reform amendments to support. So what always happens is that a lousy reauthorization bill magically shows up a few days before the authorization expires and Members are told that there’s no time to do anything other than pass that bill and that if they vote for any amendments, the program will die and terrible things will happen and it will be all their fault.

Don’t buy into that.

He’s right. Every time reauthorization is on the table, no real debate happens, and then just before the authorization is about to run out, some loyal soldier of the surveillance brigade in Congress will scream “national security” at the top of their lungs, insist there’s no time to debate this or people will die, and then promises that we need to just re-authorize for a few more years, at which point we’ll be able to hold a debate on the surveillance.

A debate that never arrives.

But even setting aside the secret interpretation Wyden can’t discuss, his speech highlights something almost as damning: just how spectacularly the supposed “reforms” from the last reauthorization have failed. Remember, one of the big “concessions” to get the last reauthorization across the finish line was a requirement that “sensitive searches” — targeting elected officials, political candidates, journalists, and the like — would need the approval of the FBI’s Deputy Director.

This was in response to some GOP elected officials being on the receiving end of investigations during the Biden era, freaking out that the NSA appeared to be doing the very things plenty of civil society and privacy advocates had been telling them about for over a decade while they just yelled “national security” back at us.

So how are those small “reforms” working out? Here’s Wyden:

Advertisement

The so-called big reform was to require the approval of the Deputy FBI Director for these sensitive searches.

Until two months ago, the Deputy FBI Director was Dan Bongino. As most of my colleagues know, Mr. Bongino is a longtime conspiracy theorist who has frequently called for specious investigations of his political opponents. This is the man whom the President and the U.S. Senate put in charge of these incredibly sensitive searches. And Bongino’s replacement as Deputy Director, Andrew Bailey, is a highly partisan election denier who recently directed a raid on a Georgia election office in an effort to justify Donald Trump’s conspiracy theories. I don’t know about my colleagues, but this so-called reform makes me feel worse, not better.

So the grand reform that was supposed to provide meaningful oversight of the FBI’s most sensitive surveillance activities ended up placing that authority in the hands of a conspiracy theorist, followed by a partisan election denier. And just to make the whole thing even more farcical, Wyden notes that the FBI has refused to even keep a basic record of these searches:

But it’s even worse than it looks. The FBI has refused to even keep track of all of the sensitive searches the Deputy Director has considered. The Inspector General urged the FBI to just put this information into a simple spreadsheet and they refused to do it. That is how much the FBI does not want oversight.

They won’t maintain a spreadsheet. The Inspector General asked them to track their use of a sensitive surveillance power using what amounts to a basic Excel file, and the FBI said no. That’s the state of “reform” for Section 702 after the last re-auth.

Wyden has also been sounding the alarm about the expansion of who can be forced to spy on behalf of the government, thanks to a provision jammed into the last reauthorization that expanded the definition of “electronic communications service provider” to cover essentially anyone with access to communications equipment. As Wyden explained:

Advertisement

Two years ago, during the last reauthorization debacle, something really bad happened. Over in the House, existing surveillance law was changed so that the government could force anyone with “access” to communications to secretly collect those communications for the government. As I pointed out at the time, that could mean anyone installing or repairing a cable box, or anyone responsible for a wifi router. It was a jaw-dropping expansion of authorities that could end up forcing countless ordinary Americans to secretly help the government spy on their fellow citizens.

The Biden administration apparently promised to use this authority narrowly. But, of course, the Trump administration has made no such promise. As we say with every expansion of executive authority, just imagine how the worst possible president from the opposing party would use it. And now we don’t have to wonder any more.

Wyden correctly points out that secret promises from a prior administration are worth exactly nothing:

But here’s the other thing – whatever secret promise the Biden Administration made about using these vast, unchecked authorities with restraint, the current administration clearly isn’t going to feel bound by that promise. So whatever the previous administration intended to accomplish with that provision, there is absolutely nothing preventing the current administration from conscripting those cable repair and tech support men and women to secretly spy on Americans.

So to tally this up: Congress is about to vote on reauthorizing Section 702 with a secret legal interpretation that Wyden says will stun the public when it’s eventually revealed, with “reforms” that placed surveillance approval authority in the hands of conspiracy theorists who won’t even keep a spreadsheet, with a massively expanded definition of who can be forced to help the government spy, with secret promises about restraint that the current administration has no intention of honoring, and with a nominee to lead the NSA who won’t commit to following the Constitution.

The Wyden Siren is blaring. And if history is any guide — and it has been, without exception — whatever is behind the classification curtain is worse than what we can see from the outside.

OpenAI acquires TBPN, the buzzy founder-led business talk show

Published

on

OpenAI has acquired popular tech industry talk show TBPN — Technology Business Programming Network — making this the AI giant’s first acquisition of a media company. The show will report to OpenAI’s chief political operative, Chris Lehane.

TBPN, hosted by former tech founders John Coogan and Jordi Hays, is a daily live show that airs on YouTube and X for three hours, focusing on tech, business, AI, and defense.

The show has gained a cult following in Silicon Valley, a safe space where industry power players can speak candidly and be questioned by fellow insiders. The show has a reputation for being something of a Sports Center for the tech industry — a place where top tech CEOs like Mark Zuckerberg, Satya Nadella, Marc Benioff, and, yes, Sam Altman, come to chop it up, react to the news of the day, and occasionally make some of their own.

TBPN will continue to live on as its own brand, which OpenAI will help scale. Not that it necessarily needed help on that front; TBPN has grown into an empire that’s on track to pull in more than $30 million this year, according to The Wall Street Journal.

OpenAI already has its own podcast for long-form conversations with the people building tech at the company.

OpenAI will also tap the founders’ “amazing comms and marketing instincts” outside the show, according to OpenAI’s head of AGI deployment, Fidji Simo, who said TBPN will “bring AI to the world in a way that helps people understand the full impact of this technology on their daily lives.”

Simo went even further, noting that TBPN’s prowess is necessary for an atypical company like OpenAI where “the standard communications playbook just doesn’t apply.”

She said TBPN will have editorial independence and continue to “run their programming, choose their guests, and make their own editorial decisions.”

Still, the acquisition might give some pause. After all, OpenAI is a valuable AI lab on the brink of an IPO buying a buzzy talk show that often discusses the company and its competitors. And once the deal closes, TBPN will operate under OpenAI’s strategy team and report to Chris Lehane, the man who invented the phrase “vast right-wing conspiracy” as a tool to deflect press scrutiny of the Clinton White House.

Lehane, who has been described as a master of the “political dark arts,” is also behind the crypto industry super PAC Fairshake, which spent hundreds of millions to kneecap anti-crypto candidates in the 2024 election. He joined OpenAI that same year and has been in President Trump’s ear ever since, whispering recommendations for sweeping and controversial policies like preventing states from regulating AI and easing environmental restrictions that might slow data center construction.

OpenAI CEO Sam Altman, who said in a social media post that TBPN is his favorite tech show, seems to believe the acquisition won’t change TBPN’s commentary and even criticism of the company.

“I don’t expect them to go any easier on us, am sure I’ll do my part to help enable that with occasional stupid decisions,” he wrote.

TBPN, meanwhile, sees the acquisition as a means to do more than just commentary.

“While we’ve been critical of the industry at times, after getting to know Sam and the OpenAI team, what stood out most was their openness to feedback and commitment to getting this right,” Hays said in a statement. “Moving from commentary to real impact in how this technology is distributed and understood globally is incredibly important to us.”

Amazon is in talks to buy Globalstar for $9 billion

Published

on

A deal would give Amazon’s Leo satellite programme access to Globalstar’s L-band spectrum and operational infrastructure, a shortcut in its race to rival SpaceX’s Starlink. Apple’s stake, which powers Emergency SOS on iPhones, has made negotiations significantly more complex.


Amazon is in advanced talks to acquire satellite telecommunications group Globalstar in a deal that would value the company at approximately $9 billion, the Financial Times reported on Wednesday, citing people familiar with the matter. Reuters confirmed the report.

Both Amazon and Globalstar declined to comment, and the two sides are still negotiating the complexities of a potential deal after what the FT describes as lengthy talks. Nothing has been signed.

The strategic rationale is straightforward. Amazon is building Amazon Leo, formerly known as Project Kuiper,  a planned constellation of more than 3,200 low-earth-orbit satellites designed to rival SpaceX’s Starlink, the dominant player in satellite internet.

Advertisement

As of the time of the report, Amazon has launched more than 180 Leo satellites. Globalstar would accelerate that ambition considerably, bringing with it L-band and S-band spectrum licences, finite, strategically valuable radio frequencies that cannot simply be replicated by launching more satellites, along with decades of operational expertise and existing ground infrastructure serving enterprise, government, and consumer markets globally.

Globalstar turned profitable in 2025 and recorded $273 million in revenue.

The complication is Apple. In 2024, Apple invested $1.5 billion in Globalstar, acquiring a 20% stake in the company, in a deal that enabled Globalstar to order additional satellites and underpin Apple’s Emergency SOS via Satellite feature on iPhone 14 and later models and Apple Watch Ultra.

That stake has made Amazon’s negotiations considerably more complex, requiring Amazon to engage with Apple directly over the terms of any acquisition.

Apple’s reliance on Globalstar’s network for a core iPhone safety feature is not merely a financial stakeholder situation: it creates a genuine operational dependency that any acquirer would need to resolve.

Globalstar’s shares surged following the FT’s report, reaching an 18-year high in after-hours trading, driven in large part by investor recognition of the value of its spectrum holdings.

For Amazon, a successful acquisition would compress years of infrastructure development into a single transaction, providing a more immediate platform from which to challenge Starlink across individual consumers, businesses, and government customers, the same segments Starlink already serves, including US national security agencies through its Starshield variant.

Whether a deal can be structured that satisfies Apple’s operational requirements while serving Amazon’s competitive ambitions remains the central question.

EPA Flags Microplastics, Pharmaceuticals As Contaminants In Drinking Water

Published

on

An anonymous reader quotes a report from NPR: Responding to public health concerns about microplastics and pharmaceuticals in the nation’s drinking water, the Trump administration for the first time has placed them on a draft list of contaminants maintained by the Environmental Protection Agency. The EPA announced the move Thursday, touting it as a “historic step” for the Make America Healthy Again, or MAHA, movement, which often raises concerns about toxic chemicals and plastic pollution in our food and environment. Also Thursday, the Department of Health and Human Services announced a $144 million initiative, called STOMP, to develop tools to measure and monitor microplastics in drinking water and in a later stage, to remove them.

The Safe Drinking Water Act requires the EPA to publish an updated version of its Contaminant Candidate List every five years. This is the sixth iteration of the list. Microplastics and pharmaceuticals appear in the draft of the upcoming list, alongside per- and polyfluoroalkyl substances, or PFAS, and dozens of other chemicals and microbes. Their inclusion on the list gives local regulators a tool to evaluate risks in their water supply, the EPA says, and it can set the stage for more research and regulatory action — but doesn’t actually guarantee that will happen.

OpenAI brings ChatGPT’s Voice mode to CarPlay

Published

on

In a surprise release, OpenAI has made ChatGPT’s Voice mode available through Apple CarPlay. If you’re running the latest version of both iOS and the ChatGPT app, and own a CarPlay-compatible vehicle, you can check out the experience. To get started, download all the necessary software, connect your iPhone to CarPlay and select “New voice chat” from ChatGPT. When the in-app text indicates ChatGPT is “listening,” you can start a conversation.

There are some notable limitations to using ChatGPT Voice with CarPlay. For one, OpenAI’s chatbot can’t control car functions. If you want to adjust the cabin temperature or skip tracks, you’ll still need Siri for those tasks. Due to Apple’s restrictions, you also can’t start using ChatGPT through a wake word like you can Siri. For example, to resume a previous conversation, you need to open the ChatGPT app from CarPlay and tap a recent or pinned chat.

With those limitations in mind, OpenAI suggests you can use Voice mode to get how-to advice, brainstorm ideas and practice languages. Personally, I like to listen to podcasts and music when I’m driving, but if talking with ChatGPT is your thing, you do you.

Nintendo NES ACEMAGIC Retro X5 Mini PC
The ACEMAGIC Retro X5’s mere presence on a desk is enough to stop most people in their tracks and have them take a closer look. It’s a simple gray and black box that pays homage to the original NES console but is far smaller in size. It measures 5.5 inches wide, 5 inches deep, and is less than 2 inches tall, making it easy to fit into small areas or pack in a suitcase for travel.



Up front, there are a handful of USB connections, a USB C slot, and a normal audio jack next to the red power button. To be honest, it has an old-school feel. When you press that button, the machine boots up quickly thanks to the solid state drive inside. Ventilation slots on either side keep it looking sleek, and the back panel provides a variety of connection options.

The Threadless Ball Screw Never Took Off, But Don’t Write It Off

Published

on

If you’ve never heard of the threadless ball screw, which was invented over sixty years ago, [Angus] of Maker’s Muse has a video demonstrating the whole thing, covering its history and showcasing both its strengths and weaknesses. If you like seeing mechanical assemblies in action, give it a watch.

The device — consisting of little more than a smooth rod and three angled ball bearings — is a way to turn rotational motion into linear motion. Not a single belt, thread, or complex mechanical assembly in sight. While a simple nut on a threaded rod can turn rotation into linear motion, those come with their own issues. The threadless ball screw was one effort at finding a better way.

While it lacks precision, the threadless ball screw nevertheless offers quiet and smooth motion with adjustable tension in a very DIY-friendly design.

Threadless ball screws never really took off, although they were given some consideration for use in 3D printers back in the RepRap days. Today one can purchase quality CNC components without leaving one’s web browser, but back in the early 2000s things like lead screws and ball screws were rather more specialized, less accessible, and more expensive than they are today. RepRap folks had to make their own solutions. But while the threadless ball screw is a very DIY-friendly design, it was ultimately lacking in performance.

The main problem is they’re just not precise enough for anything like CNC work. [Angus] does some back-and-forth tests with a 3D printed unit that shows serious drift after only a few minutes. Now, he knows perfectly well that his 3D-printed test unit is far from ideal, but the rapidity at which it drifted was still a surprise. Making a carriage with two threadless ball screws — one at each end — performed a lot better, but was ultimately still flawed.

It’s not all bad. There’s zero backlash. They are mechanically simple, remarkably smooth, and utterly quiet. Also, [Angus] discovered that the maximum force this setup can be made to apply is surprisingly significant, and is directly related to the tension on the bearings. That means one can trivially adjust how easily the carriage slips  (or doesn’t) just by tightening or loosening the screw holding each bearing.

Advertisement

Sure, they’re not precise. But maybe you don’t need precision. Maybe you just need to move something back and forth in a strong & silent sort of way that can still slip gracefully (and quietly) if something goes awry, like bottoming out an axis. 3D printing makes it pretty easy to whip one up, so maybe there’s still a place for the threadless ball screw.

5G covers under 40% of landmass. This Whitepaper details how 3GPP Release 17 addresses six satellite challenges: delay, Doppler, path loss, polarization, spectrum, and architecture.

What Attendees will Learn

  1. Why non-terrestrial networks are now integral to the 5G roadmap — Understand how the Third Generation Partnership Project (3GPP) Release 17 incorporates satellite-based connectivity into the 5G system, targeting ubiquitous coverage across maritime, remote, and polar regions where terrestrial networks reach less than 40% of the world’s landmass. Learn the distinction between New Radio non-terrestrial networks for mobile broadband and Internet of Things non-terrestrial networks for low-power machine-type communications.
  2. How satellite constellation design shapes coverage, capacity, and latency — Examine how orbit altitude (low earth orbit, medium earth orbit, geostationary earth orbit), beam footprint geometry, elevation angle, and inclination determine coverage area, round-trip time, and differential delay across user equipment within a single beam. Explore the trade-offs between transparent bent-pipe and regenerative onboard-processing payload architectures.
  3. What radio frequency challenges distinguish satellite links from terrestrial propagation — Explore the six major technical challenges: high free-space path loss, time-variant Doppler, differential delay across large beam footprints, Faraday rotation of polarization through the ionosphere, and spectrum coexistence between terrestrial and non-terrestrial bands in the S-band and L-band.
  4. How 5G protocols must adapt to support non-terrestrial connectivity — Learn the specific amendments to hybrid automatic repeat request operation, timing advance control (split into common and user-equipment-specific components), random access procedure timing extensions, discontinuous reception power saving adaptations, earth-fixed tracking area management, conditional handover mechanisms, and feeder link switching for service continuity in a unique propagation environment.
