The newest security camera from Eufy — Anker’s smart home company — can see clearly in the dark, uses radar motion sensing for fewer false alerts, and records 24/7 when wired. As with other Eufy cams, the new S3 Pro has free facial recognition, package, vehicle, and pet detection, plus locally stored recorded video with no monthly fees.

Y Combinator’s next Demo Day will include in-person seats for top VCs, Garry Tan says
Y Combinator CEO Garry Tan wants to bring the famed accelerator’s Demo Day presentations back as in-person events by the end of the year.
During Tan’s opening remarks during Wednesday’s YC summer cohort Demo Day, he said this week’s Demo Day presentations will, “knock on wood,” be the final ones held entirely online. Tan added that the accelerator’s first fall cohort Demo Day, which will take place on December 4, will include an in-person element.
Demo Days are like the graduation events for startups that complete its program, where they pitch their products to investors and others in the tech ecosystem. Tan said that in-person seats will be limited and reserved for decision-making investors who have invested at least $50,000 into YC companies within the last two years.
“Think about it this way, you all now have four must-be-at events per year in San Francisco where you can catch up with friends and see the future all at the same time,” Tan said of the planned in-person event to the VCs watching online.
This switch back to in-person Demo Days is a logical move. While both the accelerator program and its Demo Days went to an online, virtual format in 2020 due to the COVID-19 pandemic, the program itself returned to being an in-person event and has been so for two years now. Meanwhile, YC has been an instrumental part of encouraging more startups to locate themselves in the Bay Area generally, and San Francisco in particular. In addition to its accelerator program, it throws numerous other in-person events for its alumni and the startup community.
Y Combinator recently expanded the number of startup cohorts each year from two to four, adding both a fall and spring batch. The first fall cohort kicks off on September 29. YC’s first spring program will launch in 2025.

Unlike most other Eufy cameras, the S3 Pro will work with Apple Home and is compatible with Apple’s HomeKit Secure Video service.
The EufyCam S3 Pro launches this week as a two-camera bundle with one HomeBase S380 for $549.99. The HomeBase 3 enables smart alerts and local storage (16GB onboard storage, expandable up to 16 TB). It also connects the S3 Pro to Apple Home, making it the first Eufy camera to work with Apple’s smart home platform since the EufyCam 2 series from 2019.
Eufy spokesperson Brett White confirmed to The Verge that the S3 Pro will be compatible with HomeKit Secure Video. Apple’s end-to-end encrypted video storage service. “The plan is for all future devices to have Apple Home compatibility, and we’re looking into grandfathering older devices, too,” said White.
The S3 Pro has a new color night vision feature called MaxColor Vision that promises “daylike footage even in pitch-dark conditions, without the need for a spotlight.” I saw a demo of this technology at the IFA tech show in Berlin this month, and it was impressive.
A camera was positioned inside a completely dark room, sending video to a monitor outside, on which I could see everything in the room as if it were daytime. Eufy says a 1/1.8-inch CMOS sensor, F1.0 aperture, and an AI-powered image signal processor power the tech.
While the color night vision doesn’t use a spotlight, the S3 Pro does include a motion-activated spotlight that Eufy says can adapt based on real-time lighting to give you the best image. The light can also be manually adjusted using the app while viewing a live stream.
New dual motion detection uses radar sensing technology combined with passive infrared (PIR) technology. This should identify people more accurately and not send alerts that there’s a person in the yard when it’s a tree blowing in the wind. Eufy says it reduces false alerts by up to 99 percent.
The S3 Pro is battery-powered with a 13,000 mAh battery that provides up to a quoted 365 days of power. A built-in solar panel can power the camera power for longer. In my testing of the EufyCam S3, which also has a built-in solar panel, I’ve not had to recharge it in over a year.
The S3 Pro’s solar panel is 50 percent larger than the S3’s, and Eufy claims it can keep the camera fully charged with just an hour of sunlight a day. Eufy also includes an external solar panel with the camera, so you can install the camera under an eave and still get power.
Eufy says the S3 Pro records up to 4K resolution and is powered by a USB-C cable. When wired, it can record 24/7 — the first consumer-level battery-powered camera from Eufy with this capability.
- Full-duplex two-way audio
- Dual-mic array that can record human voices up to 26 feet away
- A 100dB siren and motion-activated voice warnings
- A 24/7 snapshot feature that can take a photo every minute
- Activity and privacy zones
- Integration with Google Home and Amazon Alexa
- IP67 weatherproofing
- 8x digital zoom
Following some serious security and privacy incidents in 2022, Eufy has published a new list of privacy commitments on its website. The company also worked with cybersecurity expert Ralph Echemendia following the issues, and last year, he completed an assessment that, the company claims, shows it has “met all proactive and reactive security benchmarks.”
Google has hailed Rust, a memory safe programming language, as a significant factor in its ability to cut down on vulnerabilities as part of its Safe Coding initiative.
Memory access vulnerabilities often occur in programming languages that are not memory safe. In 2019, memory safety issues accounted for 76% of all Android vulnerabilities.
In response, many developers and tech giants are moving towards using memory safe languages that help them produce secure-by-design software and technology.
Vulnerabilities Rusting away
In its blog, Google presented a simulation of the transition to memory safe languages through the gradual use of memory safe code in new projects and developments over a five year period. The results showed that despite a gradual rise in code being written in memory unsafe languages, memory safety vulnerabilities dropped significantly.
This, Google says, is because vulnerabilities decay exponentially. New code that is written in memory unsafe languages often contains bugs and vulnerabilities, but as the code is reviewed and refreshed vulnerabilities are gradually removed making the code safer over time. Ergo, the main source of vulnerabilities is new code, and by prioritizing the use of memory safe programming languages when starting new projects and developments, the number of vulnerabilities drops significantly.
In Google’s own shift towards using memory safe programming languages there has been a significant drop in the number of memory-related vulnerabilities, with memory safe vulnerabilities down to 24% in 2024 – a stark contrast from 2019 and well below the industry norm of 70%.
Using memory safe languages is not a silver bullet however, and Google acknowledges that “with the benefit of hindsight, it’s evident that we have yet to achieve a truly scalable and sustainable solution that achieves an acceptable level of risk.”
The strategies for approaching memory safety vulnerabilities began with reactive patching, where memory safe vulnerabilities are prioritized by software manufacturers, leaving other issues to be exploited more rapidly.
The second approach consisted of proactive mitigating, where developers were encouraged to include mitigations such as stack canaries and control-flow integrity at the cost of execution speed, battery life, tail latencies, and memory usage. Developers were also unable to keep up with attackers’ ability to exploit vulnerabilities in new and creative ways.
Third came proactive vulnerability discovery, where the focus was on detecting vulnerabilities through ‘fuzzing’, where vulnerabilities are tracked down through the symptoms of unsafe memory. However, as Google points out, these tools are inefficient and time-intensive for teams to use and often do not spot all vulnerabilities even with multiple passes.
Google’s fourth tactic is to therefore engage in high-assurance prevention and secure-by-design development. By using programming languages such as Rust, developers know and understand the properties of the code they have written and can infer vulnerabilities based on those properties. This reduces the cost on developers by reducing the number of vulnerabilities from the start, including vulnerabilities outside of memory safe issues. This cumulative cost reduction also has the added benefit of making developers more productive.
“The concept is simple:,” the Google blog notes, “once we turn off the tap of new vulnerabilities, they decrease exponentially, making all of our code safer, increasing the effectiveness of security design, and alleviating the scalability challenges associated with existing memory safety strategies such that they can be applied more effectively in a targeted manner.”

CoulombFly, a prototype miniature solar-powered drone
Wei Shen, Jinzhe Peng and Mingjing Qi
A drone weighing just 4 grams is the smallest solar-powered aerial vehicle to fly yet, thanks to its unusual electrostatic motor and tiny solar panels that produce extremely high voltages. Although the hummingbird-sized prototype only operated for an hour, its makers say their approach could result in insect-sized drones that can stay in the air indefinitely.
Tiny drones are an attractive solution to a range of communications, spying and search-and-rescue problems, but they are hampered by poor battery life, while solar-powered versions struggle to generate enough power to sustain themselves.
As you miniaturise solar-powered drones, their solar panels shrink, reducing the amount of energy available, says Mingjing Qi at Beihang University in China. The efficiency of electric motors also declines as more energy is lost to heat, he says.
To avoid this diminishing cycle, Qi and his colleagues developed a simple circuit that scales up the voltage produced by solar panels to between 6000 and 9000 volts. Rather than using an electromagnetic motor like those in electric cars, quadcopters and various robots, they used an electrostatic propulsion system to power a 10-centimetre rotor.
This motor works by attracting and repelling alternating components with electrical charges arranged in a ring, creating torque, which spins a single rotor blade like a helicopter. The lightweight components are made with wafer-thin slivers of carbon fibre covered in extremely delicate aluminium foil. Their high voltage demands are actually a bonus, as current is reduced, leading to very low losses to heat.
“The operating current is extremely low for the same power output, resulting in almost no heat being generated by the motor. The high efficiency and low power consumption of the motor allow us to power the vehicle with a very small solar panel,” says Qi. “We have managed to get a micro-aerial vehicle to fly using natural sunlight for the first time. Before this, only very large, ultralight aircraft could achieve this.”
The researchers’ machine, which they call CoulombFly, weighs just 4.21 grams and managed a 1-hour flight before it failed mechanically. Qi says these weak points can be designed out, and future versions will effectively be able to fly indefinitely by using solar panels in the daytime and harvesting radio signals, such as 4G and Wi-Fi, for energy at night.
CoulombFly is capable of carrying a payload of 1.59 grams, which could allow for small sensors, computers or cameras. But with refined designs, the researchers think this could be increased to 4 grams, and fixed-wing versions could even carry up to 30 grams. Work is also under way to create an even smaller version of CoulombFly that has a rotor less than 1 centimetre in diameter.
