"A humanoid robot lost its head," reports Newsweek, "during the world's first free-combat tournament for full-sized humanoid robots." The Ultimate Robot Knock-out Legend competition began Thursday in Shenzhen, China, according to the article, with local robotics company EngineAI providing $40,000 of their "T800" robots (yes, named after The Terminator) to 32 participating teams from around the world: A video shared of the combat on YouTube by local news outlet Shenzhen Story, showed that even after one of the robots had its head practically knocked off its shoulders, it continued to fight, throwing punches at its opponent and kicking into the air... [White humanoid robot "White Eagle"] landed a high kick to the head of its black opponent, "Matador," which made the robot's head rock precariously in its socket before rolling completely out of place. The two continued to spar as Matador's head was swinging from its socket until eventually the robot fell, crushing its head underneath its body. Matador tried to scramble back to its feet, but its head flew off and the robot then collapsed back down. The White Eagle did a celebratory dance for the crowd as the fight concluded, and did a move that mimicked that of someone flexing their biceps. The White Eagle waited in the ring, fists still up, as Matador was carried away, occasionally doing a few more dance moves... Per a report by Global Times, the winning team will be awarded a gold championship belt worth $1.44 million (10 million yuan) by the event organizer. It's a strange fight. The robots sometimes seem unaware of where their opponent is, facing the wrong direction or throwing kicks and punches in the air. In the first round White Eagle just knocks over Matador, who then isn't able to stand back up. (And White Eagle again appears to do a victorious dance.) EngineAI's site says they aim to "promote the development of robot combat events toward greater professionalism, scale, and industrialization," while fostering innovation and global collaboration.

CNBC reports: The automotive industry's increasing use of over-the-air technology to update vehicle systems makes it more susceptible to cyberattacks, analysts say, urging more intervention in the sector... Its use represents "a unique national security concern," Gabriel Lim, senior analyst at the S. Rajaratnam School of International Studies in Singapore, told CNBC. "Aside from data privacy concerns, the potential of a foreign actor sabotaging the controls of a moving vehicle is a possibility that countries like Norway, Denmark, and Britain have expressed concerns about," Lim added. In May, the American Enterprise Institute warned that safeguarding the automotive sector was crucial to limit foreign governments' espionage capabilities. "To protect against foreign espionage threats, the US should consider additional security reviews, implement restrictions on certain foreign-made hardware and software in vehicles, and mandate increased data-collection disclosures," the report said. The concerns come as real-life tests reveal vulnerabilities. Late last year, Norwegian bus company Ruter conducted tests on two buses and found that one had potential risks linked to OTA technology. "There is access to the control system for battery and power supply via mobile network through a Romanian SIM card. In theory, therefore, this bus can be stopped or rendered inoperable by the manufacturer," the company said. The investigation by Ruter then sparked the U.K. and Denmark to conduct their own investigations... While these investigations were conducted on buses made by Chinese firm Yutong, [Siraj Ahmed Shaikh, systems security professor at the UK's Swansea University] said the issue goes beyond one manufacturer or country, as the technology becomes more pervasive. "Other sectors adopting OTA include other transport modes [such as] maritime and rail, aerospace (particularly drones), industrial machinery and robotics," he said.

"If tired or wasted passengers fall asleep in a traditional taxi or rideshare, the driver can shout or shake them awake," reports Bloomberg. "Not so in a robotaxi..." Ditto Kasendar remembers soft music drifting from the robotaxi's speakers as he rode home late at night from a friend's birthday party in 2025. The next moment, Los Angeles firefighters were opening the door and asking if he was OK. His six-minute trip had ended nearly an hour before. A remote Waymo assistant, dialling in through the car's speakers, repeatedly tried to rouse him and finally called 911 when he wouldn't stir... Kasendar's robocab nap was, unfortunately, not an isolated incident. As companies like Alphabet and Tesla bring self-driving taxis to more cities, the messier aspects of serving unpredictable humans are becoming harder to ignore. Passengers are falling asleep, spilling drinks, dropping food, vomiting, experiencing medical emergencies and, in at least two instances, giving birth in the cars. They stumble out of the vehicles and forget to close the doors, forcing the operators to pay nearby gig workers to do it. These seemingly minor nuisances are becoming a drain on municipal resources and complicating the roll-out of robotaxi service. So many robotaxi customers have nodded off in the midst of a ride that Austin police and firefighters even have a name for the incidents: "sleepers". The Texas capital recorded 99 such calls in Waymo's first nine months of service there, said Roger Patterson, a commander with Austin-Travis County Emergency Medical Services... Remote assistants monitoring the cars try talking through the speakers and checking on passengers with interior cameras. But if they get no response, company protocols often require them to call 911. And first responders have to assume the worst. Austin dispatchers treat an incident as a potential heart attack if the remote assistant can't tell whether the passenger is breathing, Patterson said. In the end, only about 3% of such calls require transporting the passenger to a hospital, he said. But the incidents tie up personnel who might be needed elsewhere.

How cheap can you build a hardware-based ad-blocking DNS filter? "Free," if you're willing to salvage some used hardware that's being thrown away. What if you aren't so lucky? In the era of the RAMageddon, even a Raspberry Pi will cost you a couple hundred bucks. But you know, you don't even need something that powerful. In fact, you can use a $5 microcontroller to build a fully functional ad-blocking filter with over 500,000 domains blocked and around 10ms latency.We know that's possible because Egyptian full-stack developer ZedAxis (@M-Abozaid on GitHub) has already built one. Using an ESP32-C3 "SuperMini" board, he's created a backup DNS for his home network that still provides ad blocking. His primary router is a Pi-hole, which is a Raspberry Pi running specialized software to manage DHCP addressing and DNS resolution with integrated ad-blocking. The SuperMini serves as a backup when the Pi-Hole is rebooting or otherwise unavailable.The specific ESP32-C3 SuperMini board that ZedAxis used. (Image credit: ZedAxis/YouTube)Strictly speaking, we haven't seen ZedAxis' creation in action, but there's no reason to believe it doesn't work. The ESP32 family of embedded Wi-Fi-enabled microcontrollers is a well-known quantity, and this functionality is by no means outside the realm of its capabilities. In fact, this specific trick allows the use of the ESP32-C3, which is a cost-reduced version of the chip that doesn't have the 8MB of PSRAM found on some higher-end models. (There are MANY variants of the ESP32.)Instead, the ESP32-C3 used by ZedAxis has just 400KB of RAM, and 4MB of flash memory. With these limited specifications, he wasn't able to store a plaintext blocklist of any real size; it's simply too much data. So, he did what any enterprising hacker would do: he started hashing the data to reduce its size. Using 40-bit FNV-1a hashes, because 32-bit would give too many collisions and 64-bit wastes too much space, he can store some 537,000 domains in the flash memory of the device.The project includes a rudimentary GUI where you can see some statistics and configure custom domains for blocking. (Image credit: ZedAxis/YouTube)The clever part isn't really the hashing, though. Rather than storing the domains themselves, the build process downloads one or more public blocklists, strips out duplicate entries and comments, hashes each remaining domain into a 40-bit value, sorts the resulting list, and writes the finished database into the ESP32's flash memory. When a DNS query arrives, the device hashes the requested hostname the same way and performs a binary search against the sorted hash table. If it finds a match, the request is blocked. Otherwise, the query is forwarded to an upstream resolver. According to ZedAxis, the finished firmware uses only around 50KB of RAM while answering blocked lookups in roughly 10 milliseconds.There's another neat compromise hiding in the design, too. The ESP32 normally reserves enough flash memory to hold two complete copies of its firmware, allowing over-the-air (OTA) updates without risking a failed flash leaving the device unbootable. If you don't care about wireless firmware updates, you can reclaim that second firmware partition for the blocklist database instead. With OTA support enabled, the project tops out at around 250,000 blocked domains. Give up OTA, and that jumps to roughly 537,000 domains on a microcontroller that you can usually buy for the price of a fast-food lunch. ZedAxis describes the price as $2; I wasn't able to find SuperMini boards any cheaper than about $5 US, but at that price there's not much need to quibble about the difference.Of course, this isn't meant to replace a proper Pi-hole or AdGuard Home installation. The ESP32 project has a rudimentary dashboard, but it doesn't provide detailed per-client statistics, historical query logs, or all the knobs and dials that make those platforms attractive. Instead, it's designed as a tiny insurance policy. It sits quietly on the network, sips only a few dozen milliamps of power, and if the primary DNS server disappears for a reboot or a power outage, clients still get filtered DNS responses instead of falling back to whatever resolver the router happens to have configured.The backup ad-blocker is barely noticeable plugged into the creator's home gateway. (Image credit: ZedAxis/YouTube)My favorite detail is that ZedAxis powers the whole thing from the USB port on the back of his ISP-provided fiber gateway, a Huawei OptiXstar home fiber gateway. The USB connection isn't carrying any data; the totality of the integration is the router saying "here's 5 volts" and the ESP32 replying "thanks." It's just that the port is a convenient power source for a device so small it practically disappears behind the router. All communications are carried out through the ESP32's integrated Wi-Fi adapter.I have no idea whether projects like this will ever become common. Probably not, because most people who want network-wide ad blocking will still buy a Raspberry Pi, a used mini PC, or run AdGuard Home in a virtual machine. Still, it's refreshing to see somebody look at a $5 microcontroller with 400KB of RAM and decide, "Sure, that'll do."
