ChatGPT allowed in International Baccalaureate essays

Posted on by

Schoolchildren are allowed to quote from content created by ChatGPT in their essays, the International Baccalaureate has said.

The IB, which offers an alternative qualification to A-Levels and Highers, said students can use the chatbot but must be clear when they are quoting its responses.

[…]

Matt Glanville, the IB’s head of assessment principles and practice, said the chatbot should be embraced as “an extraordinary opportunity”.

However, Glanville told the Times, the responses must be treated as any other source in essays.

“The clear line between using ChatGPT and providing original work is exactly the same as using ideas taken from other people or the internet. As with any quote or material adapted from another source, it must be credited in the body of the text and appropriately referenced in the bibliography,” he said.

[…]

He added: “When AI can essentially write an essay at the touch of a button, we need our pupils to master different skills, such as understanding if the essay is any good or if it has missed context, has used biased data or if it is lacking in creativity. These will be far more important skills than writing an essay, so the assessment tasks we set will need to reflect this.”

So many of these articles include fearmongering about ChatGPT, it’s good to see that the actual educators in charge are embracing the new technology and working with it – instead of ‘alarming teachers’ (which I doubt it really does)

Dow said it was recycling Singaporean shoes. Reuters found them in Indonesia

Posted on by

At a rundown market on the Indonesian island of Batam, a small location tracker was beeping from the back of a crumbling second-hand shoe store. A Reuters reporter followed the high-pitched ping to a mound of old sneakers and began digging through the pile.

There they were: a pair of blue Nike running shoes with a tracking device hidden in one of the soles.

These familiar shoes had traveled by land, then sea and crossed an international border to end up in this heap. They weren’t supposed to be here.

Five months earlier, in July 2022, Reuters had given the shoes to a recycling program spearheaded by the Singapore government and U.S. petrochemicals giant Dow Inc. In media releases and a promotional video posted online, that effort promised to harvest the rubberized soles and midsoles of donated shoes, then grind down the material for use in building new playgrounds and running tracks in Singapore.

[…]

None of the 11 pairs of footwear donated by Reuters were turned into exercise paths or kids’ parks in Singapore.

Instead, nearly all the tagged shoes ended up in the hands of Yok Impex Pte Ltd, a Singaporean second-hand goods exporter, according to the trackers and that exporter’s logistics manager. The manager said his firm had been hired by a waste management company involved in the recycling program to retrieve shoes from the donation bins for delivery to that company’s local warehouse.

But that’s not what happened to the shoes donated by Reuters. Ten pairs moved first from the donation bins to the exporter’s facility, then on to neighboring Indonesia, in some cases traveling hundreds of miles to different corners of the vast archipelago, the location trackers showed.

But I guess they are being recycled after all then? So that’s good, right?

Does the Earth’s core have an innermost core?

Posted on by

Geology textbooks almost inevitably include a cutaway diagram of the Earth showing four neatly delineated layers: a thin outer shell of rock that we live on known as the crust; the mantle, where rocks flow like an extremely viscous liquid, driving the movement of continents and the lifting of mountains; a liquid outer core of iron and nickel that generates the planet’s magnetic field; and a solid inner core. Analyzing the crisscrossing of seismic waves from large earthquakes, two Australian scientists say there is a distinctly different layer at the very center of the Earth. “We have now confirmed the existence of the innermost inner core,” said one of the scientists, Hrvoje Tkalcic, a professor of geophysics at the Australian National University in Canberra.

Dr. Tkalcic and Thanh-Son Pham, a postdoctoral researcher, estimate that the innermost inner core is about 800 miles wide; the entire inner core is about 1,500 miles wide. Their findings were published on Tuesday in the journal Nature Communications. While the cutaway diagram appears to depict clear-cut divisions, knowledge about the deep interior of Earth is unavoidably fuzzy. It is nearly 4,000 miles to the center of Earth, and it is impossible to drill more than a few miles into the crust. Most of what is known about what lies beneath comes from seismic waves — the vibrations of earthquakes traveling through and around the planet. Think of them as a giant sonogram of Earth.

Two Harvard seismologists, Miaki Ishii and Adam Dziewonski, first proposed the idea of the innermost inner core in 2002 based on peculiarities in the speed of seismic waves passing through the inner core. Scientists already knew that the speed of seismic waves traveling through this part of the Earth varied depending on the direction. The waves traveled fastest when going from pole to pole along the Earth’s axis and slowest when traveling perpendicular to the axis. The difference in speeds — a few percent faster along polar paths — arises from the alignment of iron crystals in the inner core, geophysicists believe. But in a small region at the center, the slowest waves were those traveling at a 45-degree angle to the axis instead of 90 degrees, the Harvard seismologists said. The data available then were too sparse to convince everyone.

Sneaky Clock Displays Wrong Time If It Catches You Looking at it

Posted on by

We have a soft spot for devices that subvert purpose and expectation, and that definitely sums up [Guy Dupont]’s Clock That Is Wrong. It knows the correct time, but whether or not it displays the correct time is another story. That’s because nestled just above the 7-segment display is a person sensor module, and when it detects that a person is looking towards it, the clock will display an incorrect time, therefore self-defeating both the purpose and primary use case of a clock in one stroke.

[…]

You can watch a brief video of it in action in this Twitter thread.

One interesting bit is that [Guy] uses an ESP32-based board to drive everything, but had some reservations about making a clock without an RTC. However, he found that simply syncing time over the network every 10 minutes or so using the board’s built-in WiFi was perfectly serviceable, at least for a device like this.

This reminds us a little of other clocks with subtly subversive elements, like the Vetinari Clock which keeps overall accurate time despite irregularly drifting in and out of sync. Intrigued by such ideas? You’re not alone, because there are even DIY hobby options for non-standard clock movements.

Stanford Faculty Say Anonymous Student Bias Reports Threaten Free Speech – who’d have thought that anonymous tipping off leads to abuse?!

Posted on by

“A group of Stanford University professors is pushing to end a system that allows students to anonymously report classmates for exhibiting discrimination or bias, saying it threatens free speech on campus (Warning: source paywalled; alternative source),” reports the Wall Street Journal. The Daily Beast reports: Last month, a screenshot of a student reading Hitler’s manifesto Mein Kampf was reported in the system, according to the Stanford Daily. Faculty members leading the charge to shut the system down say they didn’t know it even existed until they read the student newspaper, one comparing the system to “McCarthyism.”

Launched in 2021, students are encouraged to report incidents in which they felt harmed, which triggers a voluntary inquiry of both the student who filed the report and the alleged perpetrator. Seventy-seven faculty members have signed a petition calling on the school to investigate in hopes they toss the system out. This comes as a larger movement by Speech First, a group who claim colleges are rampant with censorship, has filed suit against several universities for their bias reporting systems.

Amazing that people at a place like Stanford didn’t get that this was going to be abused and used to scare the shit out of people – a bit like how these systems were scary in Nazi Germany, Communist Russia and China, North Korea, etc etc.

How I Broke Into a Bank Account With an AI-Generated Voice

Posted on by

On Wednesday, I phoned my bank’s automated service line. To start, the bank asked me to say in my own words why I was calling. Rather than speak out loud, I clicked a file on my nearby laptop to play a sound clip: “check my balance,” my voice said. But this wasn’t actually my voice. It was a synthetic clone I had made using readily available artificial intelligence technology.

“Okay,” the bank replied. It then asked me to enter or say my date of birth as the first piece of authentication. After typing that in, the bank said “please say, ‘my voice is my password.’”

Again, I played a sound file from my computer. “My voice is my password,” the voice said. The bank’s security system spent a few seconds authenticating the voice.

“Thank you,” the bank said. I was in.

I couldn’t believe it—it had worked. I had used an AI-powered replica of a voice to break into a bank account. After that, I had access to the account information, including balances and a list of recent transactions and transfers.

Banks across the U.S. and Europe use this sort of voice verification to let customers log into their account over the phone. Some banks tout voice identification as equivalent to a fingerprint, a secure and convenient way for users to interact with their bank. But this experiment shatters the idea that voice-based biometric security provides foolproof protection in a world where anyone can now generate synthetic voices for cheap or sometimes at no cost. I used a free voice creation service from ElevenLabs, an AI-voice company.

Now, abuse of AI-voices can extend to fraud and hacking. Some experts I spoke to after doing this experiment are now calling for banks to ditch voice authentication altogether, although real-world abuse at this time could be rare.

Signal says it will shut down in UK over Online Safety Bill, which wants to install spyware on all your devices

Posted on by

The Online Safety Bill contemplates bypassing encryption using device-side scanning to protect children from harmful material, and coincidentally breaking the security of end-to-end encryption at the same time. It’s currently being considered in Parliament and has been the subject of controversy for months.

[ something something saving children – that’s always a bad sign when they trot that one out ]

The legislation contains what critics have called “a spy clause.” [PDF] It requires companies to remove child sexual exploitation and abuse (CSEA) material or terrorist content from online platforms “whether communicated publicly or privately.” As applied to encrypted messaging, that means either encryption must be removed to allow content scanning or scanning must occur prior to encryption.

Signal draws the line

Such schemes have been condemned by technical experts and Signal is similarly unenthusiastic.

“Signal is a nonprofit whose sole mission is to provide a truly private means of digital communication to anyone, anywhere in the world,” said Meredith Whittaker, president of the Signal Foundation, in a statement provided to The Register.

“Many millions of people globally rely on us to provide a safe and secure messaging service to conduct journalism, express dissent, voice intimate or vulnerable thoughts, and otherwise speak to those they want to be heard by without surveillance from tech corporations and governments.”

“We have never, and will never, break our commitment to the people who use and trust Signal. And this means that we would absolutely choose to cease operating in a given region if the alternative meant undermining our privacy commitments to those who rely on us.”

Asked whether she was concerned that Signal could be banned under the Online Safety rules, Whittaker told The Register, “We were responding to a hypothetical, and we’re not going to speculate on probabilities. The language in the bill as it stands is deeply troubling, particularly the mandate for proactive surveillance of all images and texts. If we were given a choice between kneecapping our privacy guarantees by implementing such mass surveillance, or ceasing operations in the UK, we would cease operations.”

[…]

“If Signal withdraws its services from the UK, it will particularly harm journalists, campaigners and activists who rely on end-to-end encryption to communicate safely.”
