Submission + - Alan Turing developed a portable voice encryption device (popularmechanics.com)

smooth wombat writes: Alan Turing, one of the more famous people who worked at Bletchley Park to decipher the German Enigma coding machine, was also working on a separate project. His private papers, known as the Bayley papers for his assistant Donald Bayley who held onto the papers until his death in 2020, reveal Turning had produced a working model of a portable voice encryption device. He even demonstrated it by using a Winston Churchill speech recording.

“Weighing just 39 kg, including its power pack,” Copeland summarizes, “Delilah would be at home in a truck, a trench, or a large backpack.”

Turing’s work at Bletchley Park actually informed the Delilah experimentation he was doing at Hanslope Park, and not just because he used Red Forms, the Army-issue sheets Hanslope staffers were meant to use to alert Bletchley staffers to enemy signals, as his personal scrap paper for Delilah experiments. He drew inspiration from one of the German cipher machines they had decoded at Bletchley; not the famed Enigma machine, but rather the SZ42. While the former relied on Morse Code, the latter utilized a 5-bit telegraph code, which Copeland notes “was a forerunner of ASCII and Unicode and is still used by some ham radio operators.”

The SZ42 produced an obscuring key of telegraph characters, with an identical key produced to both the sender and receiver. If it could be done for text, Turing reasoned it could be done for sound as well.

This is the part of the story where one might say “Well, I’ve never heard of Alan Turing’s voice encoder, so the experiments must have failed.” But remarkably, they didn’t. Turing and Bayley actually did create their Delilah, and even demonstrated it using a recording of a Winston Churchill speech, “successfully encrypting, transmitting, and decrypting it.”

Instead, the reason Delilah fell to the wayside of history isn’t because it was a failure, but rather because it simply wasn’t needed anymore. By the time Turing had built and demonstrated his device, the war was over. What good was a portable voice encryptor if you had no major enemies trying to intercept your calls, the government reasoned. So funding for the project stopped, and Turing’s two-year experiment ended with a whimper. Turing’s time as an electrical engineer at Hanslope Park became a footnote in his story, if even that.

Submission + - Trump's "Made in the USA" Phone is just a reskinned HTC U24 Pro 1

necro81 writes: The heavily promoted, $499 T1 "Trump Phone" was originally said to be "Made in the USA" and ship in September 2025. Later, that was downgraded to "Assembled in the USA". Given the Trump Organization's lack of engineering or supply chain expertise, many assumed the "T1" would just be a private-label phone made by someone else. After a number of delays, the first phones are finally shipping.

iFixit has performed a teardown and concluded that the T1 is a just gold-painted 2024 HTC U24 Pro — a device from a Taiwanese company, probably using mainland China design and supply chains. In collaboration with NBC News, the iFixit team examined both phones using CT scans, side-by-side teardowns, and even reassembled a working T1 using a U24 Pro main board. As for "assembled in the USA", that may be true, in the same sense that your phone's repairman can "assemble" a phone from a handful of subassemblies sourced from someone else. Or it may have been assembled in Guangdong, China like the other U24 Pros.

iFixit sums it up: "What you have is not an 'American-Proud Design', but a phone designed in China, made in China, with the vast majority of parts sourced from China. I’m failing to find any stirring of American pride within me. I’ve certainly felt it before, so I can confirm that it is absent at this time."

Comment Re:Flywheel storage buffer (Score 2) 105

The Texas grid which is separate from the rest of the US has a size issue with balancing and peaking that ha shown up from time to time. Their grid collapse a few winters ago would (probably) not have happened if they were connected to the big grid like everyone else is.

There are two other US grids, the Eastern and Western Interconnects. They are not frequency synchronized, and there are minimal AC-DC-AC interties connecting them.

The big collapse in Texas involved about 30GW of generation going off line. Even if Texas were connected to the Eastern grid, it is unlikely that there would have been 30GW of spare capacity and 30GW of available transmission to draw on.

Perhaps relevant, ERCOT and the Texas PUC have approved the Southern Spirit 3GW HVDC transmission line that would connect ERCOT and the western edge of the TVA's transmission network. The other states that would be affected have refused to approve the project because they believe Texas will screw them over and drive their electricity prices up.

Worth saying: In Texas, it's easy to find 3.75 square miles that's so desolate it's not useful for anything else. My local power authority here in Colorado has a power-purchase agreement with a solar farm about that size. The land it's on is so poor no one has ever trying either growing crops or running livestock on it. With the panels channeling rain water into narrow strips, it might now support enough grass for a small number of sheep, but probably not enough to justify the effort. Even more convenient, the land was adjacent to an existing transmission line, so the connection cost was a smallish substation. The authority's first battery farm is going in right next to the substation. There will probably be more.

Submission + - Wi-Fi Routers Can Scan Your Body to Identify Exactly Who You Are (futurism.com) 1

JoeyRox writes: New research out of Germany’s Karlsruhe Institute of Technology found that the types of Wi-Fi routers we all have in our homes come with a major privacy vulnerability that can be used to identify any human body that comes within their range.

The study, flagged by Gizmodo, used machine learning systems to identify individuals with an accuracy rate of 99.5 percent. To do so, the researchers exploited a vulnerability in a process known as beamforming feedback information (BFI), which was introduced to allow routers to focus Wi-Fi signals on connected devices, as opposed to the older approach, which is to blanket an entire area in coverage.

While BFI is great for network connectivity, it has a major downsides for privacy. For starters, devices connected to a router using beamforming need to send constant feedback in order to be found. As routers send out and receive network feedback, the signal is inevitably impacted by real world factors like pets, walls, and people.

Making matters worse is the fact that this data is basically wide open for anyone to grab — not only is that feedback data unencrypted, it can also be accessed without ever connecting directly to the router.

Submission + - I found a second vote.gov -- and it's registered to the White House

As_I_Please writes: The Drey Dossier reports that the National Design Studio, an office created by executive order and which reports only to the White House, has been building copies of federal agency websites like vote.gov, passports.gov, login.gov and others.

What [the National Design Studio] is doing is taking the parts of the federal government that touch you directly, your prescription, your voter registration, your passport, your federal login, out of the agencies that legally own them and rebuilding them on White House infrastructure. Vote.gov belongs to the Election Assistance Commission, and the studio built a copy. Passports belong to the State Department, and the studio is building a replacement this week. Login.gov belonged to GSA, and the studio’s guy runs it now.

Trump has said publicly that this infrastructure is for other presidents, and he is right about that. It is the one thing in this story I take him at his word on. The infrastructure outlasts him. Whoever wins in 2028 inherits the websites, the vendors, the data, and the hardware, sealed and waiting.

Submission + - AI finds signs of pancreatic cancer before tumors develop (nbcnews.com)

fjo3 writes: An AI model developed at the Mayo Clinic in Rochester, Minnesota, detected abnormalities on patients’ CT scans up to three years before they were diagnosed with pancreatic cancer, according to research published this week in the journal Gut.

The scientists behind the model, which is now being evaluated in a clinical trial, trained it by feeding it CT scans from patients who had been screened for other medical conditions then were later diagnosed with pancreatic cancer. The team then had radiologists review the scans and compared their ability to find early signs of cancer to that of the AI model. The model was found to be three times better at identifying the early signs.

Submission + - Copy Fail exploit lets 732 bytes hijack Linux systems and quietly grab root (nerds.xyz)

BrianFagioli writes: A newly disclosed Linux kernel vulnerability called Copy Fail (CVE-2026-31431) allows an unprivileged user to gain root access using a tiny 732-byte script, and it works with unsettling consistency across major distributions. Unlike older exploits that relied on race conditions or fragile timing, this one is a straight-line logic flaw in the kernelâ(TM)s crypto subsystem. It abuses AF_ALG sockets and splice to overwrite a few bytes in the page cache of a target file, such as /usr/bin/su. Because the kernel executes from the page cache, not directly from disk, the attacker can inject code into a setuid binary in memory and immediately escalate privileges.

What makes this especially concerning is how quiet it is. The file on disk remains unchanged, so standard integrity checks see nothing wrong, while the in-memory version has already been tampered with. The same primitive can also cross container boundaries since the page cache is shared, raising the stakes for multi-tenant environments and Kubernetes nodes. The underlying issue traces back to an in-place optimization added years ago, now being rolled back as part of the fix. Until patched kernels are widely deployed, this is one of those bugs that feels less like a theoretical risk and more like a practical, reliable path to full system compromise.
