‘It’s quite a bit more than we expected’: satellite reveals immense scale of GPS signal tampering • Space
Tereza Pultarova:
»
An experimental satellite has mapped the scale of GPS jamming across Europe and the Middle East from space for the first time.
The data surprised the team behind the project and indicated that satellites orbiting far from Earth aren’t the only ones that experience degradation of their positioning, navigation and timing (PNT) signals, which could affect their performance and the safety of their operations.
The new measurements were made by Pulsar-0, the first satellite of the novel Pulsar navigation constellation developed by California-based Xona Space Systems. The experimental satellite orbits 310 miles (500 kilometers) above Earth, testing Xona’s technology before the company begins deploying its navigation constellation of 300 spacecraft in low Earth orbit (LEO) later this year.
The purpose of the Pulsar constellation is to provide a more resilient PNT service compared to the United State’s GPS network and other global navigation satellite systems (GNSS), such as Europe’s Galileo or China’s Beidou. The PNT signals distributed by GNSS satellites underpin many systems that our civilization relies on in everyday life, including the operation of power grids, finance operations and oil drilling.
But because GNSS satellites orbit quite far from Earth — at altitudes abve 12,000 miles (19,000 km) — the signal that ground-based receivers detect is weak and can be easily jammed.
…Russian jammers have been disrupting GNSS signals along Russia’s western borders, officially to protect the country from Ukrainian drone attacks. Every month, this interference affects tens of thousands of flights that cruise over the region. The warring parties in the Middle East, too, use jamming and spoofing to deflect drone attacks and hide the positions of illegal ships at sea.
…In the hardest-hit areas, the strength of the GPS signals at the satellite’s altitude dropped from the regular 40 decibels to as little as 10 decibels. [Decibels are logarithmic, so that’s a thousand-fold reduction in power.]
…Satellite constellations such as SpaceX Starlink also rely on GPS to avoid collisions with other spacecraft.

Elon Musk and the plot to hijack America’s broadband • The Verge
Karl Bode:
»
Bezos — along with newly minted trillionaire Elon Musk — has become one of the biggest beneficiaries of Broadband Equity, Access, and Deployment (BEAD), a $42.45bn broadband expansion program passed as part of President Joe Biden’s 2021 “Build Back Better” initiative. BEAD was intended to give long-underserved communities billions of dollars for high-quality, future-proof fiber networks.
But under President Donald Trump and a coalition of MAGA-allied tech moguls, Build Back Better has been transformed into “tear down quickly,” leaving states mired in bureaucracy and delays. Five years later, only a handful of the millions of Americans slated for an internet access upgrade actually got one, and there’s little accountability in sight.
Established in November 2021, BEAD was the flagship program addressing a rare bipartisan congressional goal: Identify broadband coverage gaps, then deploy affordable, next-generation internet access across the US by 2030.
…the election-season campaigning against BEAD succeeded in painting Biden-era broadband expansion efforts as wasteful government bureaucracy. A Trump presidency, the public was told, would fix everything.
…The infrastructure law’s text didn’t mandate construction of specific network technologies, but it explicitly called for BEAD to prioritize terrestrial fiber networks over wireless or cable broadband. Congress recognized that it would be foolish to spend thousands of dollars per home every five to 10 years to deliver obsolete connections like coaxial cable-based broadband or settle for congested “good enough” satellite networks.
[Trump’s MAGA billionaire commerce secretary Howard]] Lutnick, however, demanded state proposals be “technology neutral.” He insisted the changes would “turbocharge speed and savings,” dubbing them “the benefit of the bargain.” In reality, the changes turned BEAD’s focus toward nascent satellite internet companies run by tech moguls. It redirected $738.8m into the already deeply subsidized pockets of Elon Musk, President Trump’s biggest campaign donor, with another $311m for Bezos’ Amazon Leo.

US AI stock sell-off shakes markets from Wall Street to Asia • The Guardian
Lauren Aratani:
»
A tech sell-off shook global markets on Tuesday as attention turned away from developments in the US war with Iran and toward the future of AI companies and chipmakers that have driven stock markets to record highs.
The tech-heavy Nasdaq index closed 2.2% lower on Tuesday. The S&P 500 was also down by Tuesday afternoon, dropping 1.43% while the Dow remained steady.
All three major US indices have hit record highs this year, riding off a rush of funding to support AI technology and infrastructure. Nasdaq is up 10% for the year, while the Dow jumped 6% so far this year, breaching past 51,000 points, and the S&P 500 is up 7.3%.
But some economists have warned that the influx of AI spending is a bubble reminiscent of the dot-com bubble that burst in the early 2000s. Seven tech companies make up 30% of the S&P 500’s value.
The heavy reliance on a single industry and a few key companies has some investors wondering if it’s a matter of when, not if, there will be a burst. Those concerns have been heightened by signals from the Federal Reserve last week that it may increase interest rates, and therefore the cost of borrowing, in order to tackle rising inflation.
Those looking for signs of stumbling may have found confirmation after a series of developments on Monday. The stock market drop started when Google-parent, Alphabet, had its worst day on the market in over a year. A pair of high-profile AI researchers left the company last week, worrying investors. Alphabet’s share price had dropped 5% by closing Monday.
Elon Musk’s SpaceX, which debuted on the market on 12 June to much fanfare, dropped 16% on Monday as the company’s post-initial public offering (IPO) boost continued to ebb. On Monday, the company announced it is looking to raise $20bn in a bond sale, even after the company gained more than $85bn through its IPO, sparking concerns over the massive cost of the company’s projects.

A business model that works for creators • Substack CEO blog
Chris Best is co-founder and CEO of Substack:
»
Today we’re introducing the next phase of Substack’s native sponsorships program, with an inaugural cohort of flagship partners who are collectively investing millions of dollars into creators on Substack. If you are a Substack bestseller who is interested in participating and shaping the program, you can publish your Creator Kit now.
The deal most of the internet offers creators goes something like this: we’ll give you reach if you give us your audience. Perform for the algorithm. Hope for a minority share of a platform’s own revenue, or figure out the money part yourself. Build your following on our platform, under our rules, subject to our priorities—and if any of that changes, good luck.
Most creators accept this deal because they feel like they have no choice. The platforms are where the audiences are. And over time, the system shapes you. You learn to make things the algorithm rewards instead of things you believe in.
Substack is built on a different theory: Give publishers a direct connection to the people who believe in them. Let people pay for the work they value.
«
Wow! What is this “native sponsorship” stuff of which you speak, Mr Best?
»
Substack’s native sponsorships program makes great partnerships simple. We’re excited to work with our flagship partners, including Yahoo Scout, Whatnot, Granola, Balenciaga, T-Mobile, Polymarket, and Uber. These forward-thinking brands recognize that some of the most interesting conversations happening on the internet are driven by writers and creators on Substack. They’ll be building with, and investing millions of dollars in, the creators who choose to participate
These are not arbitrarily inserted ads. They are direct partnerships between brands and publishers who have already built robust audience-first businesses.
Creators choose who they work with. They set the creative direction. They keep full editorial independence. Our job is to take care of what they shouldn’t have to—the matchmaking, the infrastructure, the logistics—so they can stay focused on the work.

Oh, it’s advertising. And you’ll stick ads in. Maybe the E.coli of the internet, infecting anywhere that reaches a critical size, isn’t spam; it’s advertising.

The deadly rise of giant trucks and SUVs • The New York Times
Michael Keller, Eli Murray, Danielle Ivory and Irineo Cabreros:
»
For decades, American roads were steadily getting safer for pedestrians. But around 2009, the trend reversed. Since then, the number of pedestrians killed each year has risen by about 75%.
The surge in pedestrian deaths has baffled researchers. Most other wealthy countries haven’t seen similar increases, suggesting that possible culprits like smartphones don’t tell the whole story.
Other likely causes of deadly crashes, such as drunken and distracted driving, have attracted immense attention from the public and policymakers. But the trend toward ever-larger vehicles has received much less scrutiny, even after federal researchers in 2022 cautioned regulators that it was endangering pedestrians.
After analyzing federal and industry records, including never-before-examined data on vehicle dimensions, we found that the rise of large pickups and SUVs is an important factor.
Our estimate is that about 200 to 400 pedestrians a year would not have died if vehicles had remained approximately the same size over the past quarter-century. That represents about 10% of the recent increase in pedestrian deaths.
There are two reasons bigger vehicles are deadlier: they have taller hoods, and they tend to have larger blind zones.

In the UK cars had their “bull bars” – chrome rails fitted across the radiator grille, which served no purpose for anyone not constantly herding cattle – removed. But in the US there’s a strange form of Jevon’s paradox where even as fuel gets more expensive, people want bigger cars that will consume more of it as long as they can do it in a bigger car.

Was it Trump? Eli Lilly gives powerful obesity drug for mystery 79-year-old patient • Times Now Digital via MSN
»
A 79-year-old patient has received rare early access to Eli Lilly’s experimental obesity drug retatrutide through the FDA’s compassionate use program, raising questions about the identity of the recipient and prompting speculation about whether the patient could be President Donald Trump.
According to a report by STAT, the FDA program is intended to provide access to investigational treatments for patients with serious or life-threatening medical conditions when other options may not be sufficient.
The request for access to retatrutide was submitted in April by Ranganath Muniyappa, a senior clinician at the National Institutes of Health. Muniyappa cited a diagnosis of refractory obesity along with obstructive sleep apnea and pulmonary hypertension, a potentially life-threatening condition involving high blood pressure in the lungs.
STAT reported that the application attracted attention from senior health officials, a detail that suggested the patient may be particularly influential or well connected.
The patient’s identity has not been disclosed. However, based on the limited information available, STAT contacted the White House to ask whether the recipient could be President Donald Trump, who has obesity and has publicly discussed weight-loss medications.
White House spokesperson Kush Desai did not explicitly deny that Trump was the patient and instead referred questions to the Department of Health and Human Services. When asked whether Trump had obstructive sleep apnea and pulmonary hypertension, Desai pointed to Trump’s latest medical evaluation, which STAT noted did not mention either condition.
«
“Did not explicitly deny” is one of those “admitting by not refuting” circumlocutions. Which is unusual for the Trump administration; usually they would just lie. Retratrutide is currently in phase 3 (human effectiveness) trials for “obesity, type 2 diabetes, knee osteoarthritis pain, moderate-to-severe obstructive sleep apnea (OSA), chronic low back pain, cardiovascular and renal outcomes, and metabolic dysfunction-associated steatotic liver disease (MASLD).”

Newsletter writers are the next generation of media moguls • The Washington Post
Scott Nover:
»
As media organizations shed staff and audiences grow more skeptical of institutions, a growing number of journalists are finding an unlikely refuge in the newsletter.
In recent years, prominent writers and media personalities have migrated from traditional newsrooms toward newsletters: former MSNBC anchor Mehdi Hasan now runs Zeteo on Substack; tech journalist Casey Newton, formerly of the Verge, has Platformer on Ghost; former CNN reporter Oliver Darcy runs Status on beehiv, and former BuzzFeed culture writer Anne Helen Petersen authors Culture Study on Patreon.
Newsletters are built on a tried and true delivery method — email, which [Ryan] Broderick [who has his own newsletter, employing staff, called Garbage Day] calls a “50-year-old technology that breaks down on a good day.” But, he said, it’s the best we’ve got: “In a world of algorithms, email is kind of last man standing.”
In a digital landscape increasingly crowded with artificial intelligence-generated content, many readers appear willing to pay for something harder to automate: a trusted voice delivered straight to their inbox.
“The writers who will last are the ones offering what AI can’t fake,” said Jeremy Caplan, director of teaching and learning at of CUNY’s Craig Newmark Graduate School of Journalism and the founder of the tech newsletter Wonder Tools. “They have visible curiosity, expertise based on years of work or lived experience, and some fire behind their reporting, or their point of view.”
Substack, the most prominent newsletter platform, said the top 10 of its 50,000 publishers collectively earn more than $40m a year. In politics and news, more than 30 publications clear $1m annually.
Beehiiv, which launched in 2021 billing itself as a scrappier alternative to Substack, grew its revenue 80% in 2025 to $27.5m.
Email is “the last place on the web that you get to decide who you let into your space,” said Dan Oshinsky, former director of newsletters at BuzzFeed and the New Yorker who runs a consultancy called Inbox Collective.
«
Email suffers from the challenge of spam filters and overload – it’s easy to ignore – but that’s still better than life under the algorithm. If these are the future moguls, they’re as accountable as the previous ones; that is, not very. (Thanks Gregory B for the link.)

Loupe: a privacy-focused iOS app that raises awareness about what native apps can see · GitHub
Mysk Research:
»
Loupe is an iOS and iPadOS app that gives you a hands-on tour of the device fingerprinting surface. It reads real values from public iOS APIs, the same ones any third-party app can call, and shows them to you raw. The point is simple: see what your iPhone quietly exposes, and why each reading helps an app recognize you again.
Trackers don’t need your name, email, or location to recognize you online. Each reading isn’t necessarily unique on its own, but together they form a fingerprint that follows you across apps and websites.
How signals are organized.
Loupe groups every reading into three tiers, reflecting the cost of access:
• Passive — visible to any app with no prompt at all (locale, time zone, screen, battery, and more).
• Needs Permission — readings that trigger an iOS prompt (contacts, photos, location, calendars).
• Advanced — clever side-channel uses of public APIs, such as URL-scheme probing via canOpenURL and Keychain persistence across reinstalls.

This is a developer product at present which needs to be built on Xcode. But you could expect that a built version might become public in a while.
