Retina Scan for Diabetes Could Also Reduce Deaths During Pregnancy in Developing Countries

This week Bill Gates wrote a blog post about a special camera from medtech startup Remidio, which delivers high-resolution images of a patient's retina in seconds. The camera plugs into a phone running an AI system that watches for early signs of diabetes - all without needing a blood draw, eye dilation, or a dibetes specialist. It's already been used in 40 countries for more than 15 million patients. But that same hardware, with different software, can also flag the conditions that drive so many dangerous pregnancies. Gestational diabetes sharply increases the risk of pre-eclampsia [a spike in blood pressure during pregnancy responsible for half a million fetal deaths every year and 70,000 maternal deaths]... In most of rural sub-Saharan Africa or South Asia, it usually isn't screened for at all, because the standard test requires a lab. A retinal scan offers a different way in. Remidio's device is currently being used in India to screen pregnant women for conditions that drive stillbirth. And researchers are now adapting the same hardware to screen for anemia and hypertension, too... [S]mall, portable, affordable diagnostics in the hands of community health workers are exactly the kind of lever that can start to move a number that hasn't moved in a long time.

Linux Percentage of Steam Users Doubled in One Year

Steam on Linux use in March "had skyrocketed to 5.33%..." reports Phoronix, "easily the highest level we've seen Steam on Linux at since its inception more than a decade ago." So what happened in April? [April's results] point to Linux having a 4.52% marketshare on Steam, a drop of 0.81% compared to March. Year-over-year it's roughly double with Steam on Linux in April 2025 being at 2.27%. Or two years ago for April 2024, Steam on Linux was at 1.9%.

Marvel, DC, Game Publishers Launch Rival Events Saturday for Free Giveaways

The once-a-year free comic book giveaway "is splitting in two," according to a local news report. Launched in 2002 by Diamond Comic Distributor, comic book giants like Marvel and DC have historically participated together. But things changed after Diamond Comic Distributors went bankrupt in 2025, "leaving other companies to swoop in and pick up where Diamond left off." The rights to the "Free Comic Book Day" brand were sold to Universal Distribution, which plans to bring Free Comic Book Day back on Saturday. On the same day, Penguin Random House plans to launch a rival event called Comics Giveaway Day. This means you'll still get plenty of free comics, but this time they will be separated, with some coming under the Free Comic Book Day branding and others arriving under the Comics Giveaway Day branding. Free Comic Book Day will include publishers like DC, Image, Dynamite and Archie Comics. Comics Giveaway Day will include publishers such as Marvel, Dark Horse, Boom! Studios and Tokyopop... The other big change coming this year is the introduction of game publishers Wizards of the Coast and Upper Deck to the lineup, as part of Universal Distribution's Free Comic Book Day. Wizards of the Coast is known for its tabletop role-playing game Dungeons & Dragons, as well as its trading card game Magic: The Gathering. Upper Deck is best known for its sports trading cards and entertainment collectibles, along with deck-building games like the Legendary series... In addition to adding these game makers, Universal plans to expand Free Comic Book Day to include what are colloquially referred to as your friendly local game stores. Marvel's offerings this year include a special Alien, Predator & Planet of the Apes one-shot, while D.C. is offering the first chapter of their upcoming graphic novel Aquamanatee. Other comics include Avatar: The Last Airbender - Legends from Dark Horse Comics and Sonic the Hedgehog from IDW Publishing.

Email is crazy

Email is like those creaking old Terminators from the '70s which continue to function without complaining. Designed for a world that doesn't exist anymore, it has optional encryption, no built-in auth, three⁺ retrofitted security layers bolted on top, an unstandardized filtering layer and many more quirks. Yet billions of emails arrive correctly every single day. Email is not elegant but nonetheless it is Lindy. In the new age of agentic AI, we can only expect it to metamorphose into another dimension. ↫ Saurabh "Sam" Khawase The fact that email is as complicated as it is bad enough, but having it be so dominantly controlled by only a few large gatekeepers like Google and Microsoft surely isn't helping either. I feel like email is no longer really a technology individuals can actively partake in at every level; it feels much more like WhatsApp or iMessage or whatever in that we just get to send messages, and that's it. Running your own mail sever isn't only a complex endeavour, it's also a continuous cat-and-mouse game with companies like Google and Microsoft to ensure you don't end up on some shitlist and your emails stop arriving. I settled on Fastmail as my email service, and it works quite well. Still, I would love to be able to just run my own email server, or have some of my far more capable friends run one for a small group of us, but it's such a daunting and unpleasant effort few people seem to have the stomach and perseverance for it.

The day I logged 1 in every 2000 public IPv4: visualizing the AI scraper DDoS

What if you run a few online services for you and your friends, like a small git instance and a grocery list service, but you get absolutely hammered by "AI" scrapers? I cannot impress upon you, reader, that this is not only an attack that is coordinated, it is an attack that is distributed. I run a small set of services, basically only for me and my friends. I am not a hyperscaler, I am not a tech company, I am not even a small platform. I have a git forge where I put the shit I make, and a couple other services where me and my friends backup our files or write our grocery lists. I am not fucking Meta and I cannot scale the fuck up just because OpenAI or Anthropic or Meta or whoever is training a model that weeks wants to suck all the content out of my VPS ONCE MORE until it's dry. ↫ lux at VulpineCitrus So how much traffic did the author of this piece, lux, get from "AI" scraping bots? Within a time period of 24 hours, they were hammered by 2040670 unique IP addresses, 98% of which were IPv4 addresses, which means that 1 out of every 2000 publicly available IPv4 addresses were involved in the scraping. Together, they performed over 5 million requests. And just to reiterate: they were scraping a few very small, friends-only services run by some random person. This is absolutely insane. If, at this point in time, with everything that we know about just how deeply unethical every single aspect of "AI" is, you're still using and promoting it, what is wrong with you? If you're so addicted to your "AI" girlfriend's unending stream of useless, forgettable sycophantic slop, despite being aware of the damage you're doing to those around you, there's something seriously wrong with you, and you desperately need professional help. You don't need any of this. The world doesn't need any of this. Nobody likes the slop "AI" regurgitates, and nobody likes you for enabling it. Get help.

Earliest 86-DOS and PC-DOS code released as open source

Microsoft is continuing its efforts to release early versions of DOS as open source, and today we've got a special one. We're stoked today to showcase some newly available source code materials that provide an even earlier look into the development of PC-DOS 1.00, the first release of DOS for the IBM PC. A dedicated team of historians and preservationists led by Yufeng Gao and Rich Cini has worked to locate, scan, and transcribe the stack of DOS-era source listings from Tim Paterson, the author of DOS. The listings include sources to the 86-DOS 1.00 kernel, several development snapshots of the PC-DOS 1.00 kernel, and some well-known utilities such as CHKDSK. Not only were these assembler listings, but there were also listings of the assembler itself! This work offers rare insight into how MS-DOS/PC-DOS came to be, and how operating system development was done at the time, not as it was later reconstructed. ↫ Stacey Haffner and Scott Hanselman It's wild that the source code had to be transcribed from paper, including notes and changes. You can find more information about the process on Gao's website and Cini's website.
