New iPhone auto-restart feature locks encrypted data after extended inactivity

Your iPhone data just got more secure, thanks to a new feature in iOS 18.1. This update includes an important security measure designed to protect your device and its encrypted data after long periods of inactivity.

What’s new? 

Apple has introduced an Inactivity Reboot feature in iOS 18.1, which automatically reboots your iPhone if it has been idle and unlocked for more than three days. This feature uses the Secure Enclave Processor (SEP) to monitor when your iPhone was last unlocked. 

If the device stays locked for an extended period, the SEP notifies the kernel, which triggers a reboot and kills the Springboard (the core of iOS).

HOW TO PROTECT YOUR IPHONE & IPAD FROM MALWARE

Why this matters 

The main benefit of the inactivity reboot is better data protection. By forcing a reboot after prolonged idle time, the iPhone essentially wipes encryption keys from memory. Once rebooted, the phone enters an “at rest” state. This makes it nearly impossible for cybercriminals to decrypt the data. Even if the device is left powered on for an extended period, the feature ensures that outdated forensic tools used by cybercriminals won’t be able to access sensitive information.

Impact on law enforcement

Although this new security measure is a big win for privacy, it has raised concerns with law enforcement. Specifically, they are facing more challenges when trying to unlock phones for forensic analysis. However, researcher Jiska Classen points out that three days is still enough time to coordinate steps with analysts to access the device.

More ways to keep your iPhone secure

While the inactivity reboot feature is a valuable security tool, it’s not a foolproof solution. To further protect your data, consider taking these additional steps:

1. Set a strong password: Create strong passwords for your accounts and devices and avoid using the same password for multiple online accounts. Using the same password across multiple platforms will always make you more vulnerable, because if one account gets hacked, they all get hacked. Consider using a password manager to generate and store complex passwords.

2. Have strong antivirus software: The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.

3. Back up your iPhone regularly: Backups prevent data loss caused by malicious attacks. It’s a crucial step to protect your personal information. Here’s how to do it: 

  • Go to Settings 
  • Tap iCloud
  • Click iCloud Backup
  • Tap Back Up Now

4. Turn on two-factor authentication (2FA): 2FA is an extra shield that will prevent a hacker from getting into your accounts on your iPhone. Here’s how to do it:

  • Go to Settings
  • Tap your name
  • Click Sign-In & Security
  • Tap Add a Trusted Phone Number
  • Click Continue

After adding a trusted phone number, for security, when you sign in to your account on a new device or on the web, you’ll need both your password and a section factor, such as a six-digit code sent to your devices or your phone numbers. 

5. Enable Stolen Device Protection: This feature adds an extra layer of security if your iPhone is stolen by requiring biometric authentication for sensitive actions when you’re not in a familiar location. To enable it, follow these steps:

  • Go to Settings
  • Tap on Face ID & Passcode (or Touch ID & Passcode)
  • Enter your passcode if prompted
  • Scroll down to the section for Stolen Device Protection and tap on Turn On Protection

The AI talent wars are just getting started

The AI talent wars are just getting started

For my last issue of the year, I’m focusing on the AI talent war, which is a theme I’ve been covering since this newsletter launched almost two years ago. And keep reading for the latest from inside Google and Meta this week.

But first, I need your questions for a mailbag issue I’m planning for my first issue of 2025. You can submit questions via this form or leave them in the comments.

“It’s like looking for LeBron James”

This week, Databricks announced the largest known funding round for any private tech company in history. The AI enterprise firm is in the final stretch of raising $10 billion, almost all of which is going to go to buying back vested employee stock.

How companies approach compensation is often undercovered in the tech industry, even though the strategies play a crucial role in determining which company gets ahead faster. Nowhere is this dynamic as intense as the war for AI talent, as I’ve covered before. 

Advertisement

To better understand what’s driving the state of play going into 2025, this week I spoke with Naveen Rao, VP of AI at Databricks. Rao is one of my favorite people to talk to about the AI industry. He’s deeply technical but also business-minded, having successfully sold multiple startups. His last company, MosaicML, sold to Databricks for $1.3 billion in 2023. Now, he oversees the AI products for Databricks and is closely involved with its recruiting efforts for top talent.

Our conversation below touches on the logic behind Databricks’s massive funding round, what specific AI talent remains scarce, why he thinks AGI is not imminent, and more.

The following conversation has been edited for length and clarity:

Why is this round mostly to help employees sell stock? Because $10 billion is a lot. You can do a lot with that.

The company is a little over 11 years old. There have been employees that have been here for a long time. This is a way to get them liquidity.

Most people don’t understand that this is not going into the balance sheet of Databricks. This is largely going to provide liquidity for past employees, [and] liquidity going forward for current and new employees. It ends up being neutral on dilution because they’re shares that already exist. They’ve been allocated to employees and this allows them to sell those to cover the tax associated with those shares.

How much of the rapid increases in AI company valuations have to do with the talent war?

It’s real. The key thing here is that it’s not just pure AI talent — people who come up with the next big thing, the next big paper. We are definitely trying to hire those people. There is an entire infrastructure of software and cloud that needs to be built to support those things. When you build a model and you want to scale it, that actually is not AI talent, per se. It’s infrastructure talent. 

The perceived bubble that we’re in around AI has created an environment where all of those talents are getting recruited heavily. We need to stay competitive. 

Who is being the most aggressive with setting market rates for AI talent?

Advertisement

OpenAI is certainly there. Anthropic. Amazon. Google. Meta. xAI. Microsoft. We’re in constant competition with all of these companies.

Would you put the number of researchers who can build a new frontier model under 1,000?

Yeah. That’s why the talent war is so hot. The leverage that a researcher has in an organization is unprecedented. One researcher’s ideas can completely change the product. That’s kind of new. In semiconductors, people who came up with a new transistor architecture had that kind of leverage. 

That’s why these researchers are so sought after. Somebody who comes up with the next big idea and the next big unlock can have a massive influence on the ability of a company to win.

Do you see that talent pool expanding in the near future or is it going to stay constrained? 

Advertisement

I see some aspects of the pool expanding. Being able to build the appropriate infrastructure and manage it, those roles are expanding. The top-tier researcher side is the hard part. It’s like looking for LeBron James. There are just not very many humans who are capable of that. 

I would say the Inflection-style acquisitions were largely driven by this kind of mentality. You have these concentrations of top-tier talent in these startups and it sounds ridiculous how much people pay. But it’s not ridiculous. I think that’s why you see Google hiring back Noam Shazeer. It’s very hard to find another Noam Shazeer

A guy we had at my previous company that I started, Nervana, is arguably the best GPU programmer in the world. He’s at OpenAI now. Every inference that happens on an OpenAI model is running through his code. You start computing the downstream cost and it’s like, “Holy shit, this one guy saved us $4 billion.”

“You start computing the downstream cost and it’s like, ‘Holy shit, this one guy saved us $4 billion.’”

What’s the edge you have when you’re trying to hire a researcher to Databricks?

Advertisement

You start to see some selection bias of different candidates. Some are AGI or bust, and that’s okay. It’s a great motivation for some of the smartest people out there. We think we’re going to get to AGI through building products. When people use technology, it gets better. That’s part of our pitch. 

AI is in a massive growth base but it’s also hit peak hype and is on the way down the Gartner hype curve. I think we’re on that downward slope right now, whereas Databricks has established a very strong business. That’s very attractive to some because I don’t think we’re so susceptible to the hype.

Do the researchers you talk to really believe that AGI is right around the corner? Is there any consensus of when it’s coming? 

Honestly, there’s not a great consensus. I’ve been in this field for a very long time and I’ve been pretty vocal in saying that it’s not right around the corner. The large language model is a great piece of technology. It has massive amounts of economic uplift and efficiencies that can be gained by building great products around it. But it’s not the spirit of what we used to call AGI, which was human or even animal-like intelligence.

These things are not creating magical intelligence. They’re able to slice up the space that we’re calling facts and patterns more easily. It’s not the same as building a causal learner. They don’t really understand how the world works.

You may have seen Ilya Sutskever’s talk. We’re all kind of groping in the dark. Scaling was a big unlock. It was natural for a lot of people to feel enthusiastic about that. It turns out that we weren’t solving the right problem.

Is the new idea that’s going to get to AGI the test-time compute or “reasoning” approach?

No. I think it’s going to be an important thing for performance. We can improve the quality of answers, probably reduce the probability of hallucinations, and increase the probability of having responses that are grounded in fact. It’s definitely a positive for the field. But is it going to solve the fundamental problem of the spirit of AGI? I don’t believe so. I’m happy to be wrong, too.

Do you agree with the sentiment that there’s a lot of room to build more good products with existing models, since they are so capable but still constrained by compute and access?

Yeah. Meta started years later than OpenAI and Anthropic and they basically caught up, and xAI caught up extremely fast. I think it’s because the rate of improvement has essentially stopped.

Nilay Patel compares the AI model race to early Bluetooth. Everyone keeps saying there’s a fancier Bluetooth but my phone still won’t connect.

You see this with every product cycle. The first few versions of the iPhone were drastically better than the previous versions. Now, I can’t tell the difference between a three-year-old phone and a new phone. 

I think that’s what we see here. How we utilize these LLMs and the distribution that has been built into them to solve business problems is the next frontier. 

Elsewhere

  • Google gets flatter. CEO Sundar Pichai told employees this week that the company’s drip-drip series of layoffs have reduced the number of managers, directors, and VPs by 10 percent, according to Business Insider and multiple employees I spoke with who also heard the remarks. Relatedly, Pichai also took the opportunity to add “being scrappy” as a character trait to the internal definition of “Googleyness.” (Yes, that’s a real thing.) He demurred on the most upvoted employee question about whether layoffs will continue, though I’m told he did note that there will be “overall” headcount growth next year. 
  • Meta cuts a perk. File this one under “sad violin”: I’m told that, starting in early January, Meta will stop offering free EV charging at its Bay Area campuses. Keep your heads held high, Metamates.

What else you should know about

  • OpenAI teased its next o3 “reasoning” model (yes, “o2” was skipped) with impressive evals.
  • TikTok convinced the Supreme Court to hear its case just before its US ban is set to take effect. Meanwhile, CEO Shou Chew met with Donald Trump at Mar-a-Lago to (I’m assuming) get a sense of what his other options are should TikTok lose its case.
  • More tech-meets-Mar-a-Lago news: Elon Musk inserted himself into the meeting between Jeff Bezos and Trump. Robinhood donated $2 million to Trump’s inauguration. And Softbank CEO Masayoshi Son pledged to invest $100 billion into AI tech in the US, which happens to be the same number he has floated for a chip venture to compete with Nvidia.
  • Apple complained about Meta pressuring the EU to make iOS more compatible with third-party hardware. Anyone who has synced photos from the Ray-Ban Meta glasses to an iPhone will understand why this is a battle that is very important for Meta to win, especially as it gears up to release its own pair of AR glasses with a controller wristband next year. 
  • Amazon is delaying its return-to-office mandate in some cities because it doesn’t have enough office space.
  • Perplexity, which is projected to make $127 million in revenue next year, recently raised $500 million at a valuation of $9 billion. It also acquired another AI startup called Carbon to help it hook into other services, like Notion and Google Docs.

Job board

A few notable moves this week:

  • Meta promoted John Hegeman to chief revenue officer, reporting to COO Javier Olivan. Another one of Olivan’s reports, Justin Osofsky, was also promoted to be head of partnerships for the whole company, including the company’s go-to-market strategy for Llama.
  • Alec Radford, an influential, veteran OpenAI researcher who authored its original GPT research paper, is leaving but will apparently continue working with the company in some capacity. And Shivakumar Venkataraman, who was recently brought in from Google to lead OpenAI’s search efforts, has also left.
  • Coda co-founder and CEO Shishir Mehrotra will also run Grammarly now that the two companies are merging, with Grammarly CEO Rahul Roy-Chowdhury staying on as a board member. 
  • Tencent removed two directors, David Wallerstein and Ben Feder, from the board of Epic Games after the Justice Department said their involvement violated antitrust law. 
  • Former Twitter CFO Ned Segal has been tapped to be chief of housing and economic development for the city of San Francisco.

Google Street View helped police solve a missing persons case

Google Street View helped police solve a missing persons case

A Google Street View image played in role in solving a missing person investigation in Spain, according to reports from the BBC and The New York Times. The image, which can still be seen on Street View, shows what appears to be a person loading a large object into the trunk of a car, as Gizmodo points out. Another image showed someone “transporting a large white bundle in a wheelbarrow,” the BBC reports.

Part of the human remains of the missing person have been found buried in a cemetery in a town in the province of Soria and advanced technical means had to be used to locate them.

One of the clues that investigators had to solve the crime, although it was not decisive, was some images that they detected during the investigations in a location search application.

This is the Google Street View image allegedly linked to the crime.
Screenshot: Google

Though the press release doesn’t explicitly name the location application it used, a spokesperson for the Spanish National Police confirmed to The New York Times that it was Google Maps while also saying, “The image was not the key to solving the case.”

Authorities were investigating the case of a 33-year-old man who disappeared last year while visiting a partner in Tajueco, Soria, according to the Spanish outlet El País. Police arrested a woman and her ex-partner in connection with the crime in November.

Never need an EV charging station again with these rooftop solar power panels

Have you ever wondered how we could make our cars even greener? 

Well, meet Omid Sadeghpour, a forward-thinking inventor with a brilliant idea. He’s designed rooftop solar panels specifically for his Tesla Model Y. 

His project, DartSolar, harnesses solar energy while the car is parked, potentially adding up to 20 extra miles of driving range each day without ever needing to plug in. As he gets ready to roll out the next iteration, Beta2, let’s explore what makes this innovation so groundbreaking.

The concept behind DartSolar

Electric vehicles (EVs) often spend significant time parked in open spaces, making them ideal candidates for solar energy collection. Sadeghpour’s vision is simple yet effective: why not utilize the sun’s energy to charge EVs while they are stationary? This concept forms the foundation of the DartSolar project.

DartSolar isn’t just about innovation; it’s also about practicality. Imagine a rooftop solar panel that’s aerodynamic, weatherproof, theft-resistant and easy to use. It opens in just 10 seconds with the same effort required to open your car door. These panels are tough, too, built to withstand wind, rain, sand and snow, ensuring reliable performance in all conditions.

YOU WON’T BELIEVE HOW FAR VOLVO’S NEW ELECTRIC SEMI-TRUCK GOES ON A SINGLE CHARGE

The beta 1 prototype

Omid Sadeghpour’s initial prototype, known as Beta 1, was built in collaboration with Jeran Bruce at California’s Forged Makerspace. This prototype is designed with nine flexible solar panels, each rated at 175 watts, which can be deployed when the vehicle is parked. The structure is made from wood and features telescoping carbon-fiber tubes that allow for easy expansion and retraction.

Weighing in at under 165 pounds, Beta 1 remains within the roof weight capacity of the Tesla Model Y and is designed to fit within a standard U.S. parking space when fully expanded.

TESLA SEMI’S IMPRESSIVE PERFORMANCE ON ICE MARKS ANOTHER MAJOR TRIUMPH

Advancements with beta 2

Now, let’s talk about the future. Beta 2, the fifth iteration of DartSolar, takes innovation to the next level. This version swaps the wood structure for carbon fiber, cutting its height in half for better aerodynamics. The wattage capacity has also been boosted to a potential 4,000 watts, providing up to 45 miles of range per day under optimal conditions.

Here’s where things get exciting: Beta 2 introduces dynamic charging capabilities. This means the panels can charge the car while driving or in different configurations, like partially opened for better airflow or fully closed during high-speed travel. With a reduced drag loss of just 1%-2%, it’s as efficient on the road as it is when parked.

Practical applications and future prospects

The DartSolar system has the potential to serve multiple practical applications. First, it provides a viable charging solution for those venturing into remote areas where charging stations are scarce. Additionally, it acts as a backup energy source during power outages, allowing electric vehicles to remain operational even when traditional charging methods are unavailable.

Although the project is currently a DIY initiative and not yet ready for commercial release, Sadeghpour plans to share blueprints and build files on the DartSolar website. This move aims to encourage others to explore similar innovations in solar technology.
