Of the many great technological leaps made in the middle of the 20th century, one of the ones with perhaps the greatest impact on our modern life takes a back seat behind the more glamorous worlds of electronics, aeronautics, or computing. But the ancestor of the modern tractor has arguably had more of an impact on the human condition in 2025 than that of the modern computer, and if you’d been down on the farm in the 1940s you might have seen one.
The Ferguson system refers to the three-point implement linkage you’ll find on all modern tractors, the brainchild of the Irish engineer Harry Ferguson. The film below the break is a marketing production for American farmers, and it features the Ford-built American version of the tractor known to Brits and Europeans as the Ferguson TE20.
As the four-wheeled machines grew in size and their implements moved beyond the size of their horse-drawn originals, they started to encounter a new set of problems which the film below demonstrates in detail. In short, a plough simply dragged by a tractor exerts a turning force on the machine, giving the front a tendency to lift and the rear a lack of traction. The farmers of the 1920s and 1930s attempted to counter this by loading their tractors with extra weights, at the expense of encumbering them and compromising their usefulness. Ferguson solved this problem by rigidly attaching the plough to the tractor through his three-point linkage while still allowing for flexibility in its height. The film demonstrates this in great detail, showing the hydraulic control and the feedback provided through a valve connected to the centre linkage spring.

Can you feel the nip of fall in the air? That can only mean one thing: Supercon is just around the corner. The next few weeks are going to bring a blitz of Supercon-related reveals, and we’re starting off with a big one: the workshops.
Supercon is the Ultimate Hardware Conference, and you need to be there to attend a workshop. Both workshop and general admission tickets are on sale now! Don’t wait — they sell out fast.

Remember AOL? For a lot of folks, America Online was their first ISP, the place where they got their first exposure to the Internet, or at least a highly curated version of it. Remembered by the cool kids mainly as the place that the normies used as their ISP and for the mark of shame an “@aol.com” email address bore, the company nevertheless became a media juggernaut, to the point that “AOL Time Warner” was a thing in the early 2000s. We’d have thought the company was long gone by now, but it turns out it’s still around and powerful enough of a brand that it’s being shopped around for $1.5 billion. We’d imagine a large part of that value comes from Yahoo!, which previous owner Verizon merged with AOL before selling most of the combined entity off in 2021, but either way, it’s not chump change.
For our part, the most memorable aspect of AOL was the endless number of CDs they stuffed into mailboxes in the 90s. There was barely a day that went by that one of those things didn’t cross your path, either through the mail or in free bins at store checkouts, or even inside magazines. They were everywhere, and unless you were tempted by the whole “You’ve got mail!” kitsch, they were utterly useless; they didn’t even make good coasters thanks to the hole in the middle. So most of the estimated 2 billion CDs just ended up in the trash, which got us thinking: How much plastic was that? A bit of poking around indicates that a CD contains about 15 grams of polycarbonate, so that’s something like 30,000 metric tonnes! To put that into perspective, the Great Pacific Garbage Patch is said to contain “only” around 80,000 metric tonnes of plastic. Clearly the patch isn’t 37% AOL CDs, but it still gives one pause to consider how many resources AOL put into marketing.
This week, Hackaday’s Elliot Williams and Kristina Panos met up over the tubes to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous seven days or so.
In Hackaday news, we’ve got a new contest running! Read all about the 2025 Component Abuse Challenge, sponsored by DigiKey, and check out the contest page for all the details. In sad news, American Science & Surplus are shuttering online sales, leaving just the brick and mortar stores in Wisconsin and Illinois.
On What’s That Sound, it’s a results show, which means Kristina gets to take a stab at it. She missed the mark, but that’s okay, because [Montana Mike] knew that it was the theme music for the show Beakman’s World, which was described by one contestant as “Bill Nye on crack”.
After that, it’s on to the hacks and such, beginning with a really cool way to smooth your 3D prints in situ. JWe take a much closer look at that talking robot’s typewriter-inspired mouth from about a month ago. Then we discuss several awesome technological feats such as running code on a PAX credit card payment machine, using the alphabet as joinery, and the invention of UTF-8 in general. Finally, we discuss the detection of spicy shrimp, and marvel at the history of email.

Hardly a week goes by that there isn’t a story to cover about malware getting published to a repository. Last week it was millions of downloads on NPM, but this week it’s something much more concerning. Malware published on NPM is now looking for NPM tokens, and propagating to other NPM packages when found. Yes, it’s a worm, jumping from one NPM package to another, via installs on developer machines.
It does other things too, like grabbing all the secrets it can find when installed on a machine. If the compromised machine has access to a Github account, a new repo is created named Shai-Hulud, borrowed from the name of the sandworms from Dune. The collected secrets and machine info gets uploaded here, and a workflow also uploads any available GitHub secrets to the webhook.site domain.
How many packages are we talking about? At least 187, with some reports of over 500 packages compromised. The immediate attack has been contained, as NPM has worked to remove the compromised packages, and apparently has added filtering code that blocks the upload of compromised packages.
So far there hasn’t been an official statement on the worm from NPM or its parent companies, GitHub or Microsoft. Malicious packages uploaded to NPM is definitely nothing new. But this is the first time we’ve seen a worm that specializes in NPM packages. It’s not a good step for the trustworthiness of NPM or the direct package distribution model.
For the most part, the Radio Apocalypse series has focused on the radio systems developed during the early days of the atomic age to ensure that Armageddon would be as orderly an affair as possible. From systems that provided backup methods to ensure that launch orders would reach the bombers and missiles, to providing hardened communications systems to allow survivors to coordinate relief and start rebuilding civilization from the ashes, a lot of effort went into getting messages sent.
Strangely, though, the architects of the end of the world put just as much thought into making sure messages didn’t get sent. The electronic village of mid-century America was abuzz with signals, any of which could be abused by enemy forces. CONELRAD, which aimed to prevent enemy bombers from using civilian broadcast signals as navigation aids, is a perfect example of this. But the growth of civil aviation through the period presented a unique challenge, particularly with the radio navigation system built specifically to make air travel as safe and reliable as possible.
Balancing the needs of civil aviation against the possibility that the very infrastructure making it possible could be used as a weapon against the U.S. homeland is the purpose of a plan called Security Control of Air Traffic and Air Navigation Aids, or SCATANA. It’s a plan that cuts across jurisdictions, bringing military, aviation, and communications authorities into the loop for decisions regarding when and how to shut down the entire air traffic system, to sort friend from foe, to give the military room to work, and, perhaps most importantly, to keep enemy aircraft as blind as possible.
