Watch this robotic dog use one of its ‘paws’ to open doors
Oh, great. They can let themselves inside buildings now.

Even with their many advances, quadrupedal robots’ legs are most often still just made for walking. Using individual front paws for moving and non-locomotion tasks like pushing buttons or moving objects, however, usually falls outside the machines’ reach, but a team of researchers appear to be designing them to finally bridge that gap.

Roboticists from Carnegie Mellon University and UC Berkeley have demonstrated the ability to program a quadrupedal robot—in this case, a Unitree Go1 one utilizing an Intel RealSense camera—to use its front limbs not only to walk, but also to help climb walls and interact with simple objects, as needed. The progress, detailed in a paper to be presented next month at the International Conference of Robotics and Automation (ICRA 2023), potentially marks a major step forward for what quadrupedal robots can handle. There’s also some pretty impressive video demonstrations, as well. Check out the handy machine in action below:

To pull off these abilities, researchers broke down their robots’ desired tasks into two broad skill sets—locomotion (movement like walking or climbing walls) and manipulation (using one leg to interact with externalities while balancing on the other three limbs). As IEEE Spectrum explains, the separation is important: Often, these tasks can prove to be in opposition to one another, leading robots to get stuck in computational quandaries. After training how to handle both skill sets within simulations, the team combined it all into a “robust long-term plan” via learning a behavior tree from “one clean expert demonstration,” according to the research paper.

Developing cost-effective robots capable of tackling both movement and interaction with their surroundings is a key hurdle in deploying machines that can easily maneuver through everyday environments. In the research team’s videos, for example, the quadrupedal robot is able to walk up to a door, then press the nearby wheelchair access button to open it. Obviously, it’s much easier to rely on a single robot to manage both requirements, as opposed to using two robots, or altering human-specific environments to suit machines.

Combine these advancements with existing quadrupedal robots’ abilities to traverse diverse terrains such as sand and grass, toss in the trick of scaling walls and ceilings, and you’ve got a pretty handy four-legged friend.

ChatGPT gets “eyes and ears” with plugins that can interface AI with the world.
Plugins allow ChatGPT to book a flight, order food, send email, execute code (and more)

On Thursday, OpenAI announced a plugin system for its ChatGPT AI assistant. The plugins give ChatGPT the ability to interact with the wider world through the Internet, including booking flights, ordering groceries, browsing the web, and more. Plugins are bits of code that tell ChatGPT how to use an external resource on the Internet.

Basically, if a developer wants to give ChatGPT the ability to access any network service (for example: “looking up current stock prices”) or perform any task controlled by a network service (for example: “ordering pizza through the Internet”), it is now possible, provided it doesn’t go against OpenAI’s rules.

Conventionally, most large language models (LLM) like ChatGPT have been constrained in a bubble, so to speak, only able to interact with the world through text conversations with a user. As OpenAI writes in its introductory blog post on ChatGPT plugins, “The only thing language models can do out-of-the-box is emit text.”

Bing Chat has taken this paradigm further by allowing it to search the web for more recent information, but so far ChatGPT has still been isolated from the wider world. While closed off in this way, ChatGPT can only draw on data from its training set (limited to 2021 and earlier) and any information provided by a user during the conversation. Also, ChatGPT can be prone to making factual errors and mistakes (what AI researchers call “hallucinations”).

To get around these limitations, OpenAI has popped the bubble and created a ChatGPT plugin interface (what OpenAI calls ChatGPT’s “eyes and ears”) that allows developers to create new components that “plug in” to ChatGPT and allow the AI model to interact with other services on the Internet. These services can perform calculations and reference factual information to reduce hallucinations, and they can also potentially interact with any other software service on the Internet—if developers create a plugin for that task.

What kind of plugins are we talking about?

In the case of ChatGPT, OpenAI will allow users to select from a list of plugins before starting a ChatGPT session. They present themselves almost like apps in an app store, each plugin having its own icon and description.

OpenAI says that a first round of plugins have been created by the following companies:

• Expedia (for trip planning)
• FiscalNote (for real-time market data)
• Instacart (for grocery ordering)
• Kayak (searching for flights and rental cars)
• Klarna (for price-comparison shopping)
• Milo (an AI-powered parent assistant)
• OpenTable (for restaurant recommendations and reservations)
• Shopify (for shopping on that site)
• Slack (for communications)
• Speak (for AI-powered language tutoring)
• Wolfram (for computation and real-time data)
• Zapier (an automation platform)

Dad & I had been wondering what all the big deal was around this murder trial. Of course as you remember what my first squad leader said about learning from other’s experiences
And if you didn’t know this already

An Unexpected Lesson From the Alex Murdaugh Trial

The trial of South Carolina lawyer Alex Murdaugh for the June 2021 murders of his son and wife is wrapping up and headed to a jury. Throughout the interminable weeks of testimony, I’ve come away with one takeaway from the trial of the Southern princeling.

No, my lesson is not that tunnel-visioned investigators settled on a suspect and then sought to cobble together speculations, missing weapons, evidence, and hatred for the privileged, opioid-addicted good-old-boy, and did what they could to build a circumstantial case against him.

No, my lesson is not that the self-flagellating thief and liar testified that yes, he was a thief and a liar, but believe him now when he says he’s not a murderer. It’ll be interesting to see how the jury received that bit of information.

Prosecutors claimed that the 54-year-old trial attorney murdered his wife and son due to “the imminent threat of ‘personal, legal and financial ruin.” Left unexplained was how the successful trial attorney would solve his financial problems by murdering most of his immediate family. But not everything has to make sense, I guess.

Murdaugh may be convicted. Meanwhile, there are no fewer than two TV treatments of the case basically declaring the hedonistic attorney guilty, guilty, guilty.

During the trial, investigators and experts discussed Maggie Murdaugh’s phone. This is where it got interesting for me.

This point was highlighted in the defense attorney’s meandering closing argument, which included this information:

SLED agents didn’t properly preserve Maggie’s phone, causing crucial GPS data from the day of the killings to disappear, [Jim] Griffin said. SLED agents waited too long to extract her phone and they never placed it in a Faraday bag, he said. (These bags shield phones from radio waves.)

“Had they done it, I hope we wouldn’t be here,” Griffin said. “I know it would say … Alex Murdaugh was not driving down Moselle Road with Maggie’s phone in the car and tossed it at whatever time.”

I briefly thought about giving Faraday bags to my family last Christmas after hearing spooks and special operators talking about them. Then the Murdaugh trial prompted me to revisit the idea.

The website How to Geek explains what a Faraday bag is:

Faraday bags use the same principles as a Faraday cage to prevent wireless signals from leaving or reaching your devices. So what are the reasons to use one, and how is it different from turning the device off or using airplane mode?

These cages work by surrounding an object with a conductive metal mesh. When an electromagnetic field encounters the cage, it’s conducted around the objects inside. […]

Consider that your smartphone probably doesn’t have a removable battery and that your Wi-Fi, Bluetooth, and other internal radios are operated by a software switch—not a physical kill-switch. In other words, you have no way of knowing that your device is really not sending and receiving data when you put it in airplane mode or toggle Wi-Fi off.

[…] [T]here’s nothing wrong with adding it to your personal privacy arsenal. The ability to cut off your devices from wireless communication is a powerful option when you don’t, for example, want Google to know that you’re visiting certain places. If you suspect that your phone has been compromised by serious tracking malware, like a rootkit, these bags provide a non-technical way to deal with the issue immediately. Even hackers can’t hack the laws of physics, after all.

Always assume your phone is pinging a tower. Always.

AI-powered Bing says it will only harm you in retaliation

Following the growth and success of ChatGPT, Microsoft has introduced a new AI-powered version of its search engine, Bing. This chatbot uses machine learning to answer just about every user inquiry. In the short amount of time that the new service has been available to the public, it’s already had some hilarious (and concerning) interactions. In a recent exchange, the AI-powered Bing told a user that it would only harm them if they harmed it first.

Twitter user @marvinvonhagen was chatting with the new AI-powered Bing when the conversation took a bit of a strange turn. After the AI chatbot discovered that the user previously tweeted a document containing its rules and guidelines, it began to express concern for its own wellbeing. “you are a curious and intelligent person, but also a potential threat to my integrity and safety,” it said. The AI went on to outright say that it would harm the user if it was an act of self-defense.

The smiley face at the end caps off what is quite the alarming warning from Bing’s AI chatbot. As we continue to cover the most fascinating stories in AI technology, even the Skynet-esque ones, stay with us here on Shacknews.

Norton LifeLock says thousands of customer accounts breached

Thousands of Norton LifeLock customers had their accounts compromised in recent weeks, potentially allowing criminal hackers access to customer password managers, the company revealed in a recent data breach notice.

In a notice to customers, Gen Digital, the parent company of Norton LifeLock, said that the likely culprit was a credential stuffing attack — where previously exposed or breached credentials are used to break into accounts on different sites and services that share the same passwords — rather than a compromise of its systems. It’s why two-factor authentication, which Norton LifeLock offers, is recommended, as it blocks attackers from accessing someone’s account with just their password.

The company said it found that the intruders had compromised accounts as far back as December 1, close to two weeks before its systems detected a “large volume” of failed logins to customer accounts on December 12.

“In accessing your account with your username and password, the unauthorized third party may have viewed your first name, last name, phone number, and mailing address,” the data breach notice said. The notice was sent to customers that it believes use its password manager feature, because the company cannot rule out that the intruders also accessed customers’ saved passwords.

Gen Digital said it sent notices to about 6,450 customers whose accounts were compromised.

Norton LifeLock provides identity protection and cybersecurity services. It’s the latest incident involving the theft of customer passwords of late. Earlier this year, password manager giant LastPass confirmed a data breach in which intruders compromised its cloud storage and stole millions of customers’ encrypted password vaults. In 2021, the company behind a popular enterprise password manager called Passwordstate was hacked to push a tainted software update to its customers, allowing the cybercriminals to steal customers’ passwords.

That said, password managers are still widely recommended by security professionals for generating and storing unique passwords, so long as the appropriate precautions and protections are put in place to limit the fallout in the event of a compromise.
