175 million people in Brazil now use its instant-payment system "Pix", developed by the country's central bank for real-time payments using QR codes or keys, and American Banker notes that the central banks of Argentina and Costa Rica also have developed their own widely used digital systems for instant payments. Latin America has been able to build up sleek and effective payment systems in record time because it is not held back by legacy payment technology that isn't built for instant money movement. In the likes of the U.K., U.S. and Europe, payment systems are built on infrastructure that is often decades old. The process of building new systems is therefore incredibly operationally complex. Money must continue moving, so these systems can't just be "switched off." Emerging markets, such as those in Latin America, did not have to contend with legacy technology on the same scale. Many of these communities were cash dominant until recently, due to the high fees associated with card usage and the lack of banking infrastructure in rural regions. However, while many people didn't have a local bank on their corner, they did have mobile phones... Through these digital channels, money moves instantly, via account-to-account transfers, QR codes and mobile wallets... Beyond this, real-time and traceable digital payments generate valuable cash-flow data that can transform credit underwriting for small and medium-size businesses, or SMEs. Historically, many SMEs in emerging and cash-reliant markets have struggled to access credit due to a lack of documented transaction histories, audited accounts or formal credit records... Mexico is now poised to be the next success story. In Mexico, a third of people are unbanked, but 96% of the population owns a mobile phone. This creates the perfect launchpad for a digital-first payment system that can reach those historically excluded from traditional banking systems. In fact, something already changed in 2025. Bloomberg reports that for the first time, digital payment transfers in the U.S.-to-Mexico remittance corridor exceeded cash transfers (with physical pickup locations like Western Union), according to Mexico's central bank. It's part of a Latin American market "worth more than $160 billion a year, roughly $62 billion of which goes to Mexico." And Mexico's digitalization efforts will continue, according to the country's president, who said at a March banking conference that digital payments will now be encouraged for gasoline and tolls.

Arizona state prosecutors allege Kalshi is running an illegal gambling operation, charging the prediction market with 20 "wagering" misdemeanors. But Friday a federal judge "temporarily barred Arizona from enforcing its gambling laws against predictive market operators," reports the Associated Press, "and put the brakes on a criminal wagering case that the state has filed against Kalshi. "U.S. District Judge Michael Liburdi's ruling means a Monday arraignment hearing for Kalshi has been called off." The order was issued in a lawsuit filed by the Trump administration. The judge's order said the federal Commodity Futures Trading Commission had sufficiently shown that "event contracts" fall within the Commodity Exchange Act's definition of "swaps," and that it had demonstrated a reasonable chance of success in showing that the act preempts Arizona law... The commission had sued Arizona in response to cease-and-desist letters sent to Kalshi from state gambling regulators and the criminal charges filed against the prediction market operator. The commission argued Arizona is intruding on its exclusive federal power to regulate national swaps markets... Earlier this month, the federal government filed lawsuits against Connecticut, Arizona and Illinois challenging their efforts to regulate prediction market operators. The Trump administration has so far backed the platforms. President Donald Trump's eldest son is an adviser for both Kalshi and Polymarket and an investor in the latter. Trump's social media platform Truth Social is also launching its own cryptocurrency-based prediction market called Truth Predict. Federal and state judges in Nevada and Massachusetts have now issued early rulings in favor of states looking to ban Kalshi and its competitor Polymarket from offering sports being in their states, according to the article, "while federal judges in New Jersey and Tennessee have ruled in favor of Kalshi." And Arizona's attorney general's office said it disagrees with the court's ruling and "will evaluate our next steps."

"Breathable oxygen has been created from Moon dust," reports the Telegraph, "in a world first that paves the way for a lunar base." Jeff Bezos's Blue Origin ""announced this week that it had developed a reactor that could successfully release oxygen from lunar soil by using an electric current." Almost half of Moon dust - the thin layer of rock that blankets the lunar surface - is oxygen, but it is bound to metals such as iron and titanium... Previous work to isolate oxygen has been lab-based, and the unwieldy equipment needed has been too difficult to send to the Moon. In contrast, Blue Origin said its small-scale reactor, named Air Pioneer, could be made flight-ready to "provide the first breath of life for a sustainable Moon base"... As well as breathable air, Blue Origin said the reactor produces other critical elements for planetary infrastructure, such as iron, aluminium and silicon for construction and electronics, as well as glass for windows and solar panel covers. The company has previously said it wants to turn the Moon, and eventually Mars, into "self-sustaining worlds where robots and humans can go beyond visiting and truly explore, grow, live, and thrive".... Blue Origin said it would need to generate around one megawatt of power to drive the reactors - about the energy it would require to power around 400 to 1,000 homes simultaneously. It envisages that each lunar settlement would have an array of nearby solar panels, generating the power needed for one reactor. Besides breathable air for astronauts, the oxygen could also be used in propellant for refuelling landers and fuel cells, Blue Origin points out - and "produced right where they're needed, and at much lower cost than being brought from Earth." Thanks to Slashdot reader fjo3 for sharing the article.

It shouldn't be a surprise that companies - and for our field, technology companies specifically - working with the defense industry tends to raise eyebrows. With things like the genocide in Gaza, the threats of genocide and war crimes against Iran, the mass murder in Lebanon, it's no surprise that western companies working with the militaries and defense companies involved in these atrocities are receiving some serious backlash. With that in mind, it seems Red Hat, owned by IBM, is desperately trying to scrub a certain white paper from the internet. Titled "Compress the kill cycle with Red Hat Device Edge", the 2024 white paper details how Red Hat's products and technologies can make it easier and faster to, well, kill people. Links to the white paper throw up 404s now, but it can still easily be found on the Wayback Machine and other places. It's got some disturbingly euphemistic content. The find, fix, track, target, engage, assess (F2T2EA) process requires ubiquitous access to data at the strategic, operational and tactical levels. Red Hat Device Edge embeds captured, analyzed, and federated data sets in a manner that positions the warfighter to use artificial intelligence and machine learning (AI/ML) to increase the accuracy of airborne targeting and mission-guidance systems. Delivering near real-time data from sensor pods directly to airmen, accelerating the sensor-to-shooter cycle. Sharing near real-time sensor fusion data with joint and multinational forces to increase awareness, survivability, and lethality. The new software enabled the Stalker to deploy updated, AI-based automated target recognition capabilities. If the target is an adversary tracked vehicle on the far side of a ridge, a UAS carrying a server running Red Hat Device Edge could transmit video and metadata directly to shooters. ↫ Red Hat white paper titled "Compress the kill cycle with Red Hat Device Edge" I don't think there's something inherently wrong with working together with your nation's military or defense companies, but that all hinges on what, exactly, said military is doing and how those defense companies' products are being used. The focus should be on national defense, aid during disasters, and responding to the legitimate requests of sovereign, democratic nations to come to their defense (e.g. helping Ukraine fight off the Russian invasion). There's always going to be difficult grey areas, but any military or defense company supporting the genocide in Gaza or supplying weapons to kill women and children in Iran is unequivocally wrong, morally reprehensible, and downright illegal on both an international and national level. It clearly seems someone at Red Hat feels the same way, as the company has been trying really hard to memory-hole this particular white paper, and considering its word choices and the state of the world today, it's easy to see why. Of course, the internet never forgets, and I certainly don't intend to let something like this slide. We all know companies like Microsoft, Oracle, and Google have no qualms about making a few bucks from a genocide or two, but it always feels a bit more traitorous to the cause when it's an open source company doing the profiting. It feels like Red Hat is trying to have its cake and eat it too, by, as an IBM subsidiary, trying to both profit from the vast sums of money sloshing around in the US military industrial complex as well as maintain its image as a scrappy open source business success story shitting bunnies and rainbows. It's a long time ago now that Red Hat felt like a genuine part of the open source community. Most of us - both outside and inside of Red Hat, I'm sure - have been well aware for a long time now that those days are well behind us, and I guess Red Hat doesn't like seeing its kill cycle this compressed.

If you want to run FreeBSD on a laptop, you're often yanked back to the Linux world of 20 years ago, with many components and parts not working and other issues such as sleep and wake problems. FreeBSD has been hard at work improving the experience of using FreeBSD on laptops, and now this has resulted in a list of laptops which work effortlessly with the venerable operating system. There's only about 10 laptops on the list so far, but they do span a range of affordability and age, with some of them surely being quite decent bargains on eBay or whatever other used stuff marketplace you use. If you want to use FreeBSD on a laptop, but don't want to face any surprises or do any difficult setup, get one of the laptops on this list - a list which will surely expand over time.

It may sound unbelievable to some, but not everyone has a datacenter beast with 128GB of VRAM shoved in their desktop PCs. Around the world people tell the tale of a particularly fierce group of Linux gamers: Those who dare attempt to play games with only 8 gigabytes of VRAM, or even less. Truly, it takes exceedingly strong resilience and determination to face the stutters and slowdowns bound to occur when the system starts running low on free VRAM. Carnage erupts inside the kernel driver as every application fights for as much GPU memory as it can hold on to. Any game caught up in this battle for resources will surely not leave unscathed. That is, until now. Because I fixed it. ↫ Natalie Vock The solution is to use cgroups to control the kernel's memory eviction policies, so that applications that should get priority when it comes to VRAM allocation - like games - don't get their memory evicted from VRAM to system RAM. Basically, evict everything else from VRAM before touching the protected application. This way, something like a game will have much more consistent access to more VRAM, thereby reducing needless memory evictions that harm performance. It's a clever solution that makes use of a ton of existing Linux tools, meaning it's also much easier to upstream, implement, and support. Excellent work.
