While Flock announced changes for its AI-powered traffic cameras, "Several of the proposed changes Flock is touting are merely retreads of previous ," complains the American Civil Liberties Union. "Flock's latest announcement still appears more focused on addressing a perceived PR problem than the significant harms its products create... [T]his is hardly the step forward Flock wants us to think it is " The ACLU continues to urge that default retention periods be shortened to 48 hours — not one week. And they warn Flock allows longer retention to any police department that asks for it, or when police officers activate "Evidence Mode" (the scope of which is not yet clear): Even if "Evidence Mode's" data retention hold only applies to hits returned on a given search, it would still retain significant amounts of location data on persons and vehicles who law enforcement do not suspect have engaged in any wrongdoing... Flock claims that its changes will provide "more local control," meaning local police can decide what types of offenses other Flock customers can search their data for... This is not new. Flock has attempted this before, and the security measure failed because users were easily able to circumvent the system's requirement that police input the purpose of their search. For example, on June 12, 2025 Flock started claiming its new "Proactive Search Term Tool" would block any "impermissible" searches, such as abortion-related searches in states like Illinois that prohibit sharing reproductive healthcare data. But police officers quickly realized they could just input "investigation" or even "hehehe" as a search reason and it would be approved. Flock later switched from an open text box to a drop-down menu of reasons, but that just offered police a list of acceptable purposes they could choose from, whether it was accurate or not. Until Flock demonstrates they can develop a reliable, workable system to prevent improper searches, this promise of local control provides nothing more than a false sense of security... While providing "Audit Assistance" to all departments makes sense, there is no evidence that the tool works consistently to address what the Washington Post observed is a growing pattern of police officers turning Flock into a personal stalking tool. While dozens of officers have recently been arrested, fired, or otherwise disciplined for misusing Flock for personal reasons, Flock claims these arrests are proof its auditing tool works. However, unless we know the number of officers misusing the system, we cannot conclude if Flock and its auditing tools are catching 95 percent of violators or 5 percent. Flock needs to have its auditing tool analyzed by an independent evaluator to determine its actual effectiveness. Until then, we don't know if the tool is a real security measure or just window dressing. Perhaps the oddest part of Flock's announcement is its claims that "now every search will require" police to input a case code... While claiming that a "search without a reason is a search that shouldn't happen in the first place," Flock's announcement fails to note how easily users have circumvented "search reason" security measures in the past... This leaves the public wondering how making an ineffective voluntary security measure mandatory will improve its functionality. Flock's "nearly $1 billion in venture capitalist funding has locked it into an operational model that seeks to trade our privacy for massive profits," concludes the ACLU's statement, as they promise to continue "The ACLU is fighting alongside communities to cancel local ALPR contracts and push lawmakers to protect our rights from this surveillance nightmare..."

"As Sony soldiers ahead with their plans to end hard copies for new PlayStation games, players are fearing a future which will force them to pay more and own less," writes Kotaku. What will prices do in a world with no physical copies to share or sell? One former Square Enix executive speculates this could actually drive down the price of games: "Digital on the PS store will likely get cheaper," posted Jacob Navok, former Square Enix business strategist. "Current prices are tied to retail. Without physical discs holding digital hostage we'll see a larger spectrum of pricing similar to steam." Navok says that the digital-only landscape will pit major publishers in constant, dynamic competition with each other... "The more the Playstation store becomes digital only, the greater this trend will accelerate," Navok follows up. "You will see more sales and dynamic pricing similar to Steam because publishers will compete among themselves to a greater extent." [O]n the other end newer games are getting increasingly expensive, even on digital platforms. The fact that Grand Theft Auto VI will be a purely digital release has not caused its price point to budge.

An anonymous reader shared this report from TechCrunch: According to data from digital intelligence provider Similarweb, Bluesky's mobile app had 10.4 million monthly active users worldwide in June 2026, down 27.2% year-over-year. In addition, mobile daily active users continued to decline, falling 25.6% year-over-year in July to around 3 million... Bluesky's app has lost more than half its monthly active users from its late-2024 high... Its quarterly average was around 22.1 million monthly active users in the fourth quarter of 2024, Similarweb's data indicates, and it declined to 10.7 million in the second quarter of 2026. That's a decline of around 52%. While Bluesky's numbers are down, those who stuck around are committed. Its smaller community remains relatively active, with a stickiness rate (the ratio of daily to monthly active users) of roughly 29% in June, about the same as Threads. For Bluesky's new CEO, Toni Schneider, these numbers may not be as concerning. The company is not entirely focused on making Bluesky (the app) succeed, but on making it possible for the underlying protocol (AT Proto) to power a growing number of social apps, services, and communities. That's something that is now taking place, as projects like BlackSky and Eurosky are growing, while some AT Proto apps like the video-focused Skylight have found early traction, too. In addition, the company has launched new products, like the AI-powered research tool Attie, and is now working on adding support for private data to Bluesky. The latter could generate new interest in Bluesky from a different type of user — those less interested in the public square, and more interested in private networking and communities. But on Threads in July of 2026, daily active users were up 21.3% year-over-year to 147 million, the article points out, and website visits were up 112% year-over-year to 471.6 million. And Threads now appears to have roughly 66% more monthly active users than X.

Saturday Disneyland announced a special Star Wars-themed collaboration with third-person shooter game Fortnite — including a slick new trailer for its Star Wars: Smuggler's Gambit quest. Visitors to Disneyland's Smuggler's Run attraction at Disney's theme parks in Orlando and in Anaheim can accept a special mission while waiting in line for the ride, according to The Hollywood Reporter. And "If they succeed, they will get a unique Forsworn Trooper Outfit in a newly-created Fortnite adventure called Smugglers Gambit set in that same universe." "Millennium Falcon: Smugglers Run | Fortnite marks the first time this attraction has reached beyond its physical walls into a connected game world — a story that starts in a queue in Orlando or Anaheim can now continue on a screen almost anywhere," said Sean Shoptaw, executive VP of Disney Games and Digital Entertainment.... "Together these experiences reflect our ambition to connect stories and worlds across formats into one converged entertainment ecosystem...." The cockpit technology in the ride was actually created using Epic's Unreal Engine, which allows for many assets from the ride to appear in Smugglers Gambit.... "Whether you're at a Disney Park or playing Fortnite with your friends, fans have new ways to keep their Star Wars adventures going," [said Adam Sussman, president of Epic Games]. "This is only the beginning of what's possible when world-class storytellers bring their creativity into Fortnite." Disney, of course, is an investor in Epic Games, and the two companies have been at work building a new world that will connect to Fortnite with all of the Disney's beloved characters... This new collaboration, however, extends to the real world for the first time, bringing some video game magic to Disney's parks, and some of that theme park magic to the video game. Disneyland will also launch a new area based on James Cameron's Avatar: The Way of Water, reports The Orange County Register — which even has a picture of the Avatar Destination ride's model, showing an enormous (and very colorful) waterfall. The model was part of Saturday's Disney fan expo "D23", showing the Disneyland Monorail traveling around the edge of the attraction (which reportedly involves a 30-person vehicle). Saturday's event also included details on the long-awaited "reimagining" of the park's Tomorrowland area, with their official blog promising "Yesterday's tomorrow, today!" Tomorrowland has some history, explains the Orange County Register: The land's first update in 1967 was dubbed the New Tomorrowland with the 1998 makeover jokingly referred to as the New, New Tomorrowland. The latest iteration is already being called the New, New, New Tomorrowland. Disneyland's Land of Tomorrow has plenty of empty spaces in need of some Imagineering magic with the Tomorrowland Theater, Star Wars Launch Bay and PeopleMover track all sitting underused. Or, as The Wrap puts it, "The problem with Tomorrowland, of course, has been keeping up with tomorrow." 1967 introduced New Tomorrowland, with Adventures Thru Inner Space, Carousel of Progress and the PeopleMover giving it the "World on the Move" theme. In 1975 Space Mountain opened and in the 1980's the Tomorrowland stage was enclosed to become a 3D theater, where "Magic Journeys" and "Captain EO" played. Star Tours also opened in the 1980's, giving the area some additional adrenaline. But an elaborate redo of the area, planned for the 1990's, was cut short due to financial woes following the opening of Disneyland Paris and were largely shuttered. (In Florida, a new Tomorrowland was approximated in the mid-1990's but not really followed through on, adopting some of the timelessness of the Jules Verne-inspired Discoveryland from Paris.) Since the 1990's, Tomorrowland in Disneyland has become largely defunct or outright abandoned... In the late 1990's, Disney tried to use the [PeopleMover] track for a high-speed attraction called Rocket Rods. The attraction never worked properly and was shuttered after just a few years. Rumor has it that the intensity of the ride vehicles actually weakened the PeopleMover track and removing the track would be time consuming and costly. So since the turn of the millennium, there has just been track above and all around Tomorrowland that sits, untouched.

Science Daily reports: Researchers showed that unencrypted signals routinely exchanged between WiFi devices and routers can be used to create radio-based images of people and recognize them within seconds. In tests involving 197 participants, the system identified individuals with nearly 100% accuracy, even from different angles and regardless of how they walked. "By observing the propagation of radio waves, we can create an image of the surroundings and of persons who are present," says Professor Thorsten Strufe from KASTEL, KIT's Institute of Information Security and Dependability. "This works similar to a normal camera, the difference being that in our case, radio waves instead of light waves are used for the recognition," explains the cybersecurity expert. Because the technique analyzes radio waves moving through a space, a person does not need to have a phone, smartwatch, or other WiFi enabled device with them. "Thus, it does not matter whether you carry a WiFi device on you or not." Even turning off your own device would not necessarily prevent the system from working. "It's sufficient that other WiFi devices in your surroundings are active...." Connected devices routinely send information back to the router to help optimize wireless communication. These signals, known as beamforming feedback information (BFI), are transmitted without encryption, meaning that anyone within range can potentially read them. By analyzing that information, the system can generate images of people from multiple viewpoints. Those images can then be used to determine a person's identity. Once the machine learning model has already been trained to recognize individuals, the identification process takes only a few seconds.
