Investors in gun-detection tech tested at NYC City Hall donated to mayor’s PAC

Earlier this year, New York City started testing a gun detection system from Evolv Technologies at City Hall and Jacobi Medical Center in the Bronx. Mayor Eric Adams, who has said he came across the system on the internet, has been talking up the tech for months as a way to help combat gun violence. Now, it has emerged that two people who donated $1 million to support Adams’ mayoral run work at companies with investments in Evolv, as the New York Daily News first reported.

The CEO of the investment firm Citadel, Kenneth Griffin, last year donated $750,000 to Strong Leadership NYC, a political action committee (PAC) that supported Adams. Jane Street Financial Services founder Robert Granieri gave $250,000, according to records.

As of May 16th, Citadel held 12,975 shares in Evolv, a publicly traded company. It holds another 89,900 for other investors as call options. Jane Street held 76,570 shares as of May 17th. The stock held by all shareholders totals 143.4 million, so both firms own a relatively small chunk of Evolv.

A spokesperson for Adams told the Daily News that the mayor didn’t recognize the names of Griffin and Granieri and wasn’t sure whether he’d met with them. The spokesperson said that before a pilot of Evolv’s system started at Jacobi Medical Center in February, the tech was being used at other city hospitals.

NYC has considered using the AI weapon detection technology in transit systems, particularly following a mass shooting on a subway train in Brooklyn last month. As Fast Company notes, Evolv charges between $2,000 and $3,000 per scanner per month for a subscription. Installing one at every subway entrance and paying staff to operate them would cost hundreds of millions of dollars per year. Given the costs, it’s unlikely that the scanners would be ubiquitous. 

The effectiveness of Evolv’s system has been brought into question too. While the company has not publicly disclosed its false positive rates, it has acknowledged the issue in promotional materials. 

Screenshots in brochures obtained by New York Focus indicated that in one three-month stretch, the system scanned 2.2 million people and there were more than 190,000 alerts. The vast majority of those were for harmless objects like umbrellas, strollers, eyeglass cases and laptops. In that scenario, only 0.8 percent of the alerts were for actual weapons and just 0.1 percent were for non-law enforcement guns. However, Evolv has claimed that the data in the screenshots is “fictitious” and is “from a demonstration account.”

A report by surveillance tech trade publication IPVM earlier this year noted that Evolv’s full-body scanners were misidentifying other objects as potential weapons, such as Chromebooks. IPVM director of operations Donald Maye told the Daily News that Evolv’s system has a false alert rate of between five and ten percent at settings such as sports stadiums (which lines up with data shown in the disputed screenshot). Maye suggested that the false positive rate would actually be higher at subway system scanners and lead to “secondary screenings” with cops searching commuters.

Engadget has contacted Evolv for comment.

Amazon no longer offers in-app Kindle and Music purchases on Android

If you use Amazon’s Kindle app on Android, you may have noticed the software doesn’t offer the option to buy and rent ebooks or subscribe to the company’s Kindle Unlimited service anymore. Amazon announced the change last month and more recently began notifying customers of the move via email.

If you’re curious about what’s going on, the change puts Amazon in compliance with a policy Google will begin enforcing on June 1st. Starting next month, the company will require all developers to process payments involving “digital goods and services” through the Play Store billing system. Previously, Amazon was among a handful of developers Google allowed to use third-party alternatives to collect in-app payments. Rather than give Google a commission for every ebook it sells on Android, Amazon has decided to remove purchases altogether. It has done the same in its Music app. In Audible, meanwhile, you can still purchase credits through the app, but it’s no longer possible to buy audiobooks directly with your credit or debit card as of version 3.23 of the software. In the US, Amazon doesn’t offer Kindle in-app purchasing on iOS either.  

It’s worth noting Amazon isn’t the only company that has stopped sales on Android. In April, for instance, Barnes and Noble removed direct purchasing from the Android version of its Nook app. Some companies have legally challenged Google on the matter, with Tinder parent company Match Group filing a suit against the search giant in May.

There’s the possibility that direct purchasing could return to Amazon’s Android Kindle, Audible and Music apps at some point in the future. In March, Google partnered with Spotify to test third-party billing systems. However, how soon that pilot could expand to include other companies is unclear.

Update 3:40PM ET: Added clarification about how purchasing works in Audible following Amazon’s response to Google’s policy change. 

Microsoft Surface Laptop Go 2 leaks in retail listing

It appears Microsoft will soon reveal its next-gen Surface Laptop Go. The successor to the would-be Chromebook competitor popped up in a Korean retailer listing that appears to have gone live a little too early. It seems the page has since been taken down.

The listing, which was spotted by The Verge, indicates the Surface Laptop Go 2 will shift from a 10th-gen Intel Core CPU to an 11th-gen Intel processor. This specific configuration boasts the i5-1135G7 and Intel Iris Xe graphics.

As with the original Surface Laptop Go from 2020, this laptop will support up to 8GB of RAM and as much as 256GB of storage, according to the listing. The base model specs are unclear, however. Previous reports indicated the laptop will have a baseline of 4GB RAM and 128GB of storage. The base Surface Laptop Go has 64GB of storage.

As you might expect, the laptop is slated to ship with Windows 11. The listing promises a battery life of up to 13.5 hours as well. In addition, it suggests the system will have “improved HD camera performance,” even though, like its predecessor, it’s said to have a 720p webcam.

The Surface Laptop Go 2 seems to have a lot of other details in common with the original system. The listing suggests it still has a 12.4-inch display and 3:2 aspect ratio, the same ports (including a 3.5mm headphone jack and the proprietary Surface charging port) and a fingerprint sensor. There’s no sign of it having a backlit keyboard as yet, unfortunately.

It seems we may not have to wait much longer for Microsoft to formally announce the latest entry-level Surface laptop. The listing suggests preorders will open on June 2nd.

Blizzard won’t release ‘Diablo Immortal’ in countries with loot box laws

Don’t expect to play Diablo Immortal in the Low Countries when it launches this week. GamesIndustry.biz and Tweakers have learned Blizzard won’t release the free-to-play game in Belgium or the Netherlands due to their “gambling restrictions” — that is, their legislation banning loot boxes. It will also be illegal for people in those countries to download them from other regions, and Blizzard’s support team warned that it couldn’t guarantee that players in the affected countries would avoid bans.

Belgium and the Netherlands determined in 2018 that some loot boxes, particularly those you can buy or trade for real money, amounted to gambling. Diablo Immortal tucks access to its best stat-enhancing items, such as some legendary gems, behind legendary crests that are often easier to obtain with real-world currency. While the items you get are frequently good (to the point where some have argued they’re unfair), the attributes are random. That could theoretically pressure gamers to pay in hopes of scoring the ‘perfect’ crest, and might reel in people with addictive personalities.

Blizzard halted loot box sales for other games in Belgium after the country cracked down on the practice. The company also isn’t unique. EA, Konami, Nintendo and Epic’s Psyonix have all pulled games to avoid violating anti-loot box laws. Even so, it’s still notable that Blizzard would rather withdraw Diablo Immortal from those countries than change gameplay mechanics.

What we bought: My first tube amp… about 20 years late

I got my first guitar in the seventh grade. Had a couple of bands in high school and college. And I still play regularly. But, I’m somewhat embarrassed to admit that I only just bought my first tube amp in April of last year. That’s right, I played guitar somewhat seriously for around 25 years before I went and bought what is considered by many (mostly obnoxious purists) the only kind of amp worth playing.

Eventually, I set my sights on a Fender Blues Jr, a simple 15-watt, 1×12 amp. Specifically, I managed to snag a gorgeous Tweed model used for $400. It was too good of a deal to pass up (even if I did have to drive into New Jersey to pick it up).

Now, before you all freak out, it’s not that I’ve never played a tube amp before. My bands often rented a rehearsal space where I was usually playing through Marshall half stack. A JCM800 if I remember correctly, but I’d be lying if I said I cared about anything other than the fact that it was a Marshall half stack at the age of 18.

When it was time for me to go out and upgrade from my tiny Yamaha practice amp, I just got the loudest thing I could afford at the time: a 2×12 120-watt Crate solid state amp. I needed something that could be heard over a drummer in my basement or in a small club. It did exactly what I expected it to: It was delightfully crisp and clean, took pedals well and it was loud.

That was my only amp for many years. But, being 120w it didn’t really do “quiet.” Even with the volume at one it was enough to piss off the neighbors. So when I had my first child I knew I needed to get something else. Again, budget and volume were important (turns out kids are expensive). But instead of being loud, this time I needed something that would sound good at levels that wouldn’t disturb a sleeping baby. So I snagged a Yamaha THR10 on sale.

But over the last few years I’d started getting serious about music again. And, in particular over the last two years, I’d rekindled my love of guitar. Between that, and what I’m going to chalk up to pandemic restlessness, I started looking to upgrade to an actual tube amp. I ended up settling on the Blues Jr in part because I still needed something that didn’t get too loud. But I also didn’t need anything terribly fancy. I wanted tube warmth and crunch at a reasonable price and without too many bells and whistles.

While it took me a while to find the amp’s sweet spots, I’m a convert. I now primarily use my THR10 late at night or if I need to be mobile – say, shooting a review in my dining room. But otherwise, I’m firing up the Blues Jr everytime. It can do the jangly clean tones often associated with Fender at lower volumes, and get an almost Vox-ish crunch when cranked. I rarely use the “Fat” switch, which boosts the mids, but I could see it being handy if you’re relying entirely on the internal drive and need to take a solo.

The only real amenity you get is a spring reverb, which sounds pretty great. Cranking it introduces a decent amount of noise to your signal, but it really nails those drippy surf tones.

Importantly for me, it has a master volume knob (which not all amps do). That allows you to push the preamp until you start to get some delicious breakup, while keeping things at a level that won’t get the cops involved. But it gets loud enough for gigging too, in case I ever decide to play music in front of other humans again (highly unlikely).

The biggest selling point, though, was that it’s also a pretty solid pedal platform. As a guitarist with more effects than talent, I needed something that wasn’t going to get too muddy or noisy as I started stacking multiple delays and reverbs with fuzz.

The Fender Blues Jr has been around since about 1995. And, while it has undergone multiple revisions in that time, its core character remains largely unchanged. Honestly, I wish I had discovered it earlier. Because, while I’ve fallen in love with plenty of instruments and effects over the years, this is the first amp that I’ve been truly enamored with.

Watch NASA’s Mars helicopter complete a record-setting flight

NASA’s Ingenuity helicopter is still pushing boundaries long after its first Mars liftoff. As CNETnotes, the space agency has shared video of Ingenuity’s milestone 25th flight on April 8th, when it broke duration and speed records. The robotic helicopter flew at 12MPH for just over two minutes and 41 seconds, providing footage of the Red Planet’s rippling sands and rock fields as part of the 2,310-foot journey. The footage you see below was sped up to cut the viewing time to 35 seconds.

The video doesn’t include the very start and end of the trip, but for good reason. The navigation camera switches off whenever Ingenuity is within three feet of the Martian surface to prevent dust from interfering with the navigation system. The autonomous flier receives flight plans from JPL, but it uses a combination of the camera, a laser rangefinder and an inertial measurement unit to adapt to real-life conditions.

Ingenuity has flown three times since. It’s currently preparing for a 29th flight following a brief scare in early May, when the mission team lost communication after the helicopter switched to a low-power state. NASA isn’t easily deterred, then — expect the aircraft to keep flying for a while to come.
