In every copy of macOS that has shipped since 2018, Apple has included the original Bitcoin whitepaper by Satoshi Nakamoto, and no-one seems to know why. From a report: The baffling discovery (or rediscovery - see below) was recently made by developer and waxy.org writer Andy Baio, who stumbled upon the PDF document while trying to fix a problem with his printer. Anyone with a Mac running macOS Mojave or later can see the PDF for themselves by typing the following command into Terminal:

open /System/Library/Image\ Capture/Devices/VirtualScanner.app/Contents/Resources/simpledoc.pdf

If you're running macOS 10.14 or later, the 184 KB Bitcoin PDF should immediately open in Preview. The document can also be located via Finder: Navigate to Macintosh HD -> System -> Library -> Image Capture -> Devices, then open the Contents -> Resources folder. The whitepaper titled "simpledoc.pdf" should be in there.

Longtime Slashdot reader destinyland shares a report from Space.com: The Relativity Space rocket, called Terran 1, lifted off from Launch Complex 16 at Florida's Cape Canaveral Space Force Station at 8:25 p.m. EST (0025 GMT on March 23), kicking off a test flight called "Good Luck, Have Fun" (GLHF). Terran 1 performed well initially. For example, it survived Max-Q -- the part of flight during which the structural loads are highest on a rocket -- and its first and second stages separated successfully. But something went wrong shortly thereafter, at around three minutes into the flight, when the rocket failed to reach orbit.

"No one's ever attempted to launch a 3D-printed rocket into orbit, and, while we didn't make it all the way today, we gathered enough data to show that flying 3D-printed rockets is viable," Relativity Space's Arwa Tizani Kelly said during the company's launch webcast on Wednesday night. "We just completed a major step in proving to the world that 3D-printed rockets are structurally viable," she added.

In the 1970s, Bob Metcalfe helped develop the primary technology that lets you send email or connect with a printer over an office network. From a report: In June 1972, Bob Metcalfe, a 26-year-old engineer fresh out of graduate school, joined a new research lab in Palo Alto, Calif., as it set out to build something that few people could even imagine: a personal computer. After another engineer gave up the job, Dr. Metcalfe was asked to build a technology that could connect the desktop machines across an office and send information between them. The result was Ethernet, a computer networking technology that would one day become an industry standard. For decades, it has connected PCs to servers, printers and the internet in corporate offices and homes across the globe.

For his work on Ethernet, the Association for Computing Machinery, the world's largest society of computing professionals, announced on Wednesday that Dr. Metcalfe, 76, would receive this year's Turing Award. Given since 1966 and often called the Nobel Prize of computing, the Turing Award comes with a $1 million prize. When Dr. Metcalfe arrived at the Palo Alto Research Center -- a division of Xerox nicknamed PARC -- the first thing he did was connect the lab to the Arpanet, the wide-area network that later morphed into the modern internet. The Arpanet transmitted information among about 20 academic and corporate labs across the country. But as PARC researchers designed their personal computer, called the Alto, they realized they needed a network technology that could connect personal computers and other devices within an office, not over long distances.

sciencehabit shares a report from Science Magazine: Researchers have designed a robot that can create and cook a cake with up to seven ingredients, more than any other printed food to date. The scientists built their programmable patisserie by retrofitting a 3D printer with nozzles designed to squeeze out selected ingredients. They then programmed it to dispense those into layered cakes. Initial trials resulted in triangular gobs of sweet goo, so the researchers came up with a winning recipe that could hold its own. They nested softer ingredients, such as jelly and banana puree, inside of stiffer ingredients, such as peanut butter and Nutella, then reinforced those with hefty doses of graham cracker crust. Then, they broiled the crust with a laser and topped the cake with frosting and cherry glaze. The result? A cheesecake, of sorts.

Despite its novelty, the computer-guided cook may not be able to battle it out under the stern eye of a guest judge any time soon -- each slice took about 30 minutes to print. Further in the future, however, better printers could make some cooking automatic, freeing people from kitchen tasks they may find tiring or repetitive -- assuming you don't enjoy those things. A food printer could also be programmed to dispense meals with precision-controlled nutrient and calorie content, helping prepare food for those on strict diets. The study has been published in the journal npj Science of Food.

"Based on initial data review, vehicle is healthy," Relativity Space tweeted today. "More info to follow on cause of aborts today. Thanks for playing."

Remaining back on the launchpad is the largest 3D printed object ever to exist. And they're still hoping to launch it into space.

They'd planned a launch this morning from Cape Canaveral, Florida of a 110-foot rocket (33.5 meters) on a mission they're calling GLHF — "Good Luck, Have Fun".

The rocket's makers — California-based Relativity Space — call it "the world's first 3D printed rocket." A full 85% of the rocket's weight comes from 3D printed parts, explains Wired, and "only the computing system, electronics, and readily available parts like fasteners were not." Named Terran 1, the 7.5-foot-wide rocket (2.2 meters) inaugurates the company's ambitious plans for 3D printing in space: Relativity Space wants to use Terran 1 to (comparatively) cheaply lift satellites for other companies and NASA into Earth orbit. It also plans to construct Terran R, a larger, more powerful, fully reusable rocket that the company hopes will compete with SpaceX's Falcon 9, which has a smaller payload capacity and only reuses the rocket's first stage. In late 2024, Relativity plans to test using Terran R to launch payloads to Mars; another startup, Impulse Space, will provide the lander.
From the company's web site: Like its structure, all Relativity engines are 3D printed and use liquid oxygen and liquid natural gas, which are not only the best for rocket propulsion, but also for reusability, and the easiest to eventually transition to methane on Mars.
The tagline for the company's Twitter feed says they're "Building humanity's multiplanetary future." And excitement is running high, reports Spaceflight Now" "There are a number of firsts here potentially on this rocket," said Josh Brost, vice president of revenue operations at Relativity Space....

"Hard to believe the day is nearly here to launch Terran 1, our first rocket!" Tim Ellis, co-founder and CEO of Relativity Space tweeted Tuesday....

The company now boasts some 1,000 employees, a million-square-foot headquarters and factory in Long Beach, California, and $1.3 billion in venture capital and equity fundraising, including an early $500,000 investment from billionaire Mark Cuban. In 2021, the company reached a valuation of $4.2 billion before launching any rockets....

"No new company has ever had their liquid rocket make it to space on their first attempt," Brost, also a former engineer and manager at SpaceX, told Spaceflight Now in a pre-launch interview. "So if everything goes incredibly well, and we achieve orbit on our first launch ... that would be a remarkable milestone for us, which we would be, of course, over the moon excited about. But that doesn't define success for us."
Wired adds that they're not the only company working on space-related 3D printing: Australia's Fleet Space has already been producing lightweight, 3D-printed radio frequency antennas for satellites. Next year, using printers half the size of a bus, they plan to create a satellite constellation called Alpha that will be entirely 3D-printed.... Flavia Tata Nardini, the company's CEO, believes space-based 3D printing is coming next. "In my ideal future, in 10 to 15 years, I won't have to launch satellites from here; I can build them up there."

An anonymous reader quotes a report from Ars Technica: HP customers are showing frustration online as the vendor continues to use firmware updates to discourage or, as users report, outright block the use of non-HP-brand ink cartridges in HP printers. HP has already faced class-action lawsuits and bad publicity from "dynamic security," but that hasn't stopped the company from expanding the practice. Dynamic security is a feature used by HP printers to authenticate ink cartridges and prevent use of cartridges that aren't HP-approved. As the company explains: "Dynamic security relies on the printer's ability to communicate with the security chips or electronic circuitry on the cartridges. HP uses dynamic security measures to protect the quality of our customer experience, maintain the integrity of our printing systems, and protect our intellectual property. Dynamic security equipped printers are intended to work only with cartridges that have new or reused HP chips or electronic circuitry. The printers use the dynamic security measures to block cartridges using non-HP chips or modified or non-HP electronic circuitry. Reused, remanufactured, and refilled cartridges that reuse the HP chip or electronic circuitry are unaffected by dynamic security."

HP is set on continuing to use DRM to discourage its printer customers from spending ink and toner money outside of the HP family. "HP have updated their printers to outright ban 'non-HP' ink! They no longer shows the 'can't guarantee quality' message, but instead cancels your print completely until you inset a HP ink cartridge," Reddit user grhhull posted Tuesday. "After contacting HP, they advised 'this is due to the recent 'update' of all printers.'" It's unclear when HP issued updates for which model printers, but there are alleged customer complaints online stemming from late last year, showing plenty of customers surprised their printer no longer worked with non-HP ink cartridges after an update. Some pointed to third-party brands they had relied on for years.

HP community support threads include complaints about the OfficeJet 7740 and OfficeJet Pro 6970. HP lists both printers, as well as others, as able to circumnavigate dynamic security under specific conditions. However, HP's support page states this only applies to models manufactured before December 1, 2016. For more examples, there are comments on HP's support community suggesting that HP's OfficeJet 6978 and 6968 were recently affected. Both printers are discontinued, but HP's product pages make it clear that the fickle nature of dynamic security means that third-party ink could stop working at any time. And HP's dynamic security page also leaves the door open for the sudden bricking of functioning ink: "Firmware updates delivered periodically over the internet will maintain the effectiveness of the dynamic security measures," the page reads. "Updates can improve, enhance, or extend the printer's functionality and features, protect against security threats, and serve other purposes, but these updates can also block cartridges using a non-HP chip or modified or non-HP circuitry from working in the printer, including cartridges that work today."

An anonymous reader quotes a report from Ars Technica: Cheap, light, flexible, yet robust circuit boards are critical for wearable electronics, among other applications. In the future, those electronics might be printed on flexible circuits made out of bacterial cultures used to make the popular fermented black tea drink called kombucha, according to a recent paper posted to the arXiv preprint server. "Nowadays kombucha is emerging as a promising candidate to produce sustainable textiles to be used as eco-friendly bio wearables," co-author Andrew Adamatzky, of the University of the West of England in Bristol, old New Scientist. "We will see that dried -- and hopefully living -- kombucha mats will be incorporated in smart wearables that extend the functionality of clothes and gadgets. We propose to develop smart eco-wearables which are a convergence of dead and alive biological matter."

Adamatzky previously co-authored a 2021 paper demonstrating that living kombucha mats showed dynamic electrical activity and stimulating responses, as well as a paper last year describing the development of a bacterial reactive glove to serve as a living electronic sensing device. Inspired by the potential of kombucha mats for wearable electronics, he and his latest co-authors have now demonstrated that it's possible to print electronic circuits onto dried SCOBY mats. The team used commercially sourced kombucha bacteria to grow their mats, then air-dried the cultures on plastic or paper at room temperature. The mats don't tear easily and are not easily destroyed, even when immersed in water for several days. One of the test mats even survived oven temperatures up to 200 C (392 F), although the mats will burn when exposed to an open flame. Adamatzky et al. were able to print conductive polymer circuits onto the dried kombucha mats with an aerosol jet printer and also successfully tested an alternative method of 3D printing a circuit out of a conductive polyester/copper mix. They could even attach small LEDs to the circuits with an epoxy adhesive spiked with silver, which were still functioning after repeatedly being bent and stretched.

According to Adamatzky et al., unlike the living kombucha mats he worked with previously, the dried SCOBY mats are non-conductive, confining the electrical current to the printed circuit. The mats are also lighter, cheaper, and more flexible than the ceramic or plastic alternatives. Potential applications include wearable heart rate monitors, for instance, and other kombucha-based devices. "Future research will be concerned with printing advanced functional circuits, capable for detecting -- and maybe recognizing -- mechanical, optical, and chemical stimuli," the authors concluded.

An anonymous reader quotes a report from Gizmodo: Wilson has been working to redesign the basketball with a prototype that's covered in an intricate pattern of holes but never goes flat. Although calling the basketball "airless" is a bit of a misnomer given air is still able to pass right through it, it's the most common term that's been used to describe this technology that replaces the need for pressurized bladders in objects designed to bounce or absorb impacts. Wilson partnered with a company called EOS which specializes in the use of 3D printing for industrial uses including medical and aerospace applications, to manufacture the unorthodox basketball design that's covered in a pattern of open hexagons instead of sealed leather panels.

EOS relied on additive 3D printing technology which, instead of building up layers of extruded melted plastic, uses a powdered resin that's hardened by a laser to create ultra-thin stacked layers with even more detail. The result is a completely hollow basketball that nearly matches the "performance specifications of a regulation basketball, including its weight, size and rebound (bounce)." The 3D-printed ball can even be dyed in various colors, with the prototype being made all-black for its debut during the 2023 NBA All-Star Game festivities this past weekend. "The NBA currently doesn't have any plans to switch to Wilson's 3D-printed airless basketball design, but that doesn't mean it's a failure," notes Gizmodo. "[E]ven if it never finds its way into the NBA, it could still help make the game more accessible on playground courts across the country where pick-up games will never have to be canceled because no one can find a pump to fix a flat ball."

The company explains how the prototype basketball was made in a video on YouTube.

A writer for the Atlantic complains that their HP printer is shaking them down like a loan shark. I discovered an error message on my computer indicating that my HP OfficeJet Pro had been remotely disabled by the company. When I logged on to HP's website, I learned why: The credit card I had used to sign up for HP's Instant Ink cartridge-refill program had expired, and the company had effectively bricked my device in response....

Instant Ink is a monthly subscription program that purports to monitor one's printer usage and ink levels and automatically send new cartridges when they run low. The name is misleading, because the monthly fee is not for the ink itself but for the number of pages printed. (The recommended household plan is $5.99 a month for 100 pages). Like others, I signed up in haste during the printer-setup process, only slightly aware of what I was purchasing. Getting ink delivered when I need it sounded convenient enough to me....

The monthly fee is incurred whether you print or not, and the ink cartridges occupy some liminal ownership space. You possess them, but you are, in essence, renting both them and your machine while you're enrolled in the program.... Here was a piece of technology that I had paid more than $200 for, stocked with full ink cartridges. My printer, gently used, was sitting on my desk in perfect working order but rendered useless by Hewlett-Packard, a tech corporation with a $28 billion market cap at the time of writing, because I had failed to make a monthly payment for a service intended to deliver new printer cartridges that I did not yet need....

There are tales of woe across HP's customer-support site, in Reddit threads, and on Twitter. A pending class-action lawsuit in California alleges that the Instant Ink program has "significant catches" and does not deliver new cartridges on time or allow those enrolled to use cartridges purchased outside the subscription service, rendering the consumer frequently unable to print. Parker Truax, a spokesperson for HP, told me, "Instant Ink cartridges will continue working until the end of the current billing cycle in which [a customer cancels]. To continue printing after they discontinue their Instant Ink subscription and their billing cycle ends, they can purchase and use HP original Standard or XL cartridges."
"Nobody told me that if I canceled, then all those cartridges would stop working," complains another owner of an HP printer cited in the article. "I guess this is our future, where your printer ink spies on you."

But the article ultimately concludes that the printer's shakedown is "just one example of how digital subscriptions have permeated physical tech so thoroughly that they are blurring the lines of ownership. Even if I paid for it, can I really say that I own my printer if HP can flip a switch and make it inert?"

A startup founded by SpaceX veterans aims to realize the potential of a technology whose big promises have never quite come through. From a report: 3D printers -- which create objects by layering materials according to a plan sent by a computer -- have gained a reputation for being unwieldy, expensive and slow. There has been more progress on industrial uses, although there, too, major players have fallen into a multiyear funk. Venture capitalists continue to dedicate significant resources to startups promising innovations to fix the technology's underlying flaws. One particularly radical approach comes from Freeform Future, a five-year-old startup based in Los Angeles. The company has raised $45 million so far from investors including Founders Fund, Threshold Ventures and Valor Equity Partners. Instead of trying to build a single machine that can print three-dimensional objects, Freeform is looking to turn entire buildings into automated 3D-printing factories that would use dozens of lasers to create rocket engine chambers or car parts from metal powder.

The company, which has never before discussed its approach publicly, says the technique could allow it to make metal parts 25 to 50 times faster than is possible with current methods and at a fraction of the cost. Freeform's co-founder and chief executive officer, Erik Palitsch, spent a 10-year stint at SpaceX, Elon Musk's aerospace company. [...] Freeform, on the other hand, is creating machines that can fill a warehouse. Its current factory, in Hawthorne, California, used to serve as Keanu Reeves's motorcycle storage facility. (Freeform still ends up with some of the actor's mail.)

Inside, machines shuffle objects back and forth along rapidly moving conveyors, so the system can work on many things at once. Other companies have set up multiple printers in a single facility, but this strategy doesn't improve their speed, it just increases scale by having them work in parallel. Freeform, by contrast, is redesigning the process by which 3D printing can turn raw materials into finished products. In a sense, it's akin to the establishment of the assembly-line process pioneered by 20th century industrialists like Henry Ford. "We have to achieve a state of mass production to open this up to more industries," says Palitsch. "And you simply can't get there with a conventional machine."

An anonymous reader quotes a report from Motherboard, written by Katie Way: MILF Manor is a reality TV show made to be dissected on the internet. Everything, from its ripped-from-30-Rock title to the Oedipal set-up of mothers and their sons thrown into the same "dating pool," is so patently outrageous that it boomerangs back into normalcy -- of course these mothers need to participate in a blindfolded contest to identify their sons by their abs alone. But MILF Manor's most understated quirk is the one that sticks out to me: There's no tanned, vaguely handsome man with veneers and a dress shirt directing the festivities. Instead, contestants receive alerts and directions via text, on iPhones in magenta cases that seem to be provided by the producers. Like more and more reality TV competition shows, there's no actual host.

By my estimation, Netflix's The Circle kicked the trend off in 2020. Its contestants, who compete to create the most lovable social media presence in physical isolation, receive prompts and challenges from a big-screen TV in their living quarters. Pressure Cooker, a more recent offering from the streaming giant, is a cooking competition show where the host is replaced by a kitchen ticket printer: Competitions receive challenge instructions and the results of game-ending votes in the same way chefs take orders from their diners. The Button, a YouTube speed dating series by the production company Cut, goes a step further with the introduction of a large talking button that cracks jokes and prompts daters to ask each other cringe-worthy questions until one of them presses it, ending the date and sending in another option.

Why axe the role of host when it's been a staple of the formula for so long? It could be a sign of the recession. Reality TV competition shows are famously among the cheapest television to produce, but if I've learned anything about business, it's that executives have never met a corner they're not dying to cut. It could also be that the role of reality TV host is not attracting the same iconic cultural figures it once was, when the subgenre exploded in popularity in the early 2000s. [...] At the core, though, I believe there's something more insidious at play: Robots are once again stealing jobs from red-blooded human workers. Only this time, instead of factory linemen or fast food cashiers, these laborers are C-List comedians and guys who are incredibly symmetrical but not quite hot. (Again, Jeff Probst, I am not talking about you!) Sure, I know machine intelligence doesn't experience emotion -- yet! -- and I know that all of these robo-hosts are likely operated by producers -- for now! But isn't toying with people in a high-stress, high-stakes situation, the exact job description of a reality competition host, the absolute dream gig for a robot? Seems a little too perfect. "Experts already predict that AI and machine learning could replace people working as couriers, investment analysts, and customer service representatives," concludes Way. "Adding reality competition show hosts to that list means the creep into our cultural landscape has already started, which is a distinctly scary thought, in my book. Our flesh is weak, our MILFs are fragile, and we are so, so vulnerable to the clinical calculations of our machine overlords -- uh, I mean, hosts."

Long-time Slashdot reader wonkavader found a video on YouTube where, at the 2:50 mark, there's time-lapse footage of soldering paste magically melting into place. The secret? Many circuit boards include a grounded plane as a layer. This doesn't have to be a big unbroken expanse of copper — it can be a long snake to reduce the copper used. Well, if you run 9 volts through that long snake, it acts as a resistor and heats up the board enough to melt solder paste. Electronics engineer Carl Bugeja has made a board which controls the 9 volt input to keep the temperature on the desired curve for the solder.

This is an interesting home-brew project which seems like it might someday make a pleasant, expected feature in kits.
Hackaday is impressed by the possibilities too: Surface mount components have been a game changer for the electronics hobbyist, but doing reflow soldering right requires some way to evenly heat the board. You might need to buy a commercial reflow oven — you can cobble one together from an old toaster oven, after all — but you still need something, because it's not like a PCB is going to solder itself. Right?

Wrong. At least if you're Carl Bugeja, who came up with a clever way to make his PCBs self-soldering.... The quality of the soldering seems very similar to what you'd see from a reflow oven.... After soldering, the now-useless heating element is converted into a ground plane for the circuit by breaking off the terminals and soldering on a couple of zero ohm resistors to short the coil to ground.
It's an open source project, with all files available on GitHub. "This is really clever," tweeted Adrian Bowyer, inventor of the open source 3D printer the RepRap Project.

In the video Bugeja compares reflow soldering to pizza-making. (If the circuit board is the underlying dough, then the electronics on top are the toppings, with the solder paste representing the sauce that keeps them in place. "The oven's heat is what bonds these individual items together.")

But by that logic making a self-soldering circuit is "like putting the oven in the dough and making it edible."

"Most companies are trying to create lab-grown meat with little to no genetic engineering, which despite shifts in attitude is still frowned on," writes Fast Company. And other companies "think that modifications like this will complicate getting regulatory approval," especially in Europe, which considers CRISPR to be a form of genetic modfication.

But then there's the cultivated meat startup SciFi Foods (formerly Artemys Foods). Fast Company reports that its CEO/cofounder Joshua March became "obsessed" with cultivated meat "after reading about it in The Player of Games, a 1988 science fiction novel by Iain M. Banks that is beloved by techies." For a while, March sat on the sidelines running other startups. "I didn't think I had to do anything," he says, "that it would happen on its own." But years ticked by, and there was little advancement in what was then usually referred to as lab-grown meat. "I honestly became pretty disenchanted with the companies in the space and all the arm waving about how the costs would be solved." If he wanted it to be a real thing in the world, he'd have to do something. He'd have to play the game.

Unlike virtually every other startup in the space — and according to the Good Food Institute, there are 152 cultivated meat companies as of the end of 2022, operating in 29 countries — March and SciFi are using CRISPR (the technology that makes gene editing as easy as using a 3D printer) to hasten its advances. To Kasia Gora, SciFi's CTO, it's merely an engineering challenge. "We take a synthetic biology approach to figuring out how to make scalable beef cell lines," she tells me. The key is engineering cycles that enable rapid prototyping. The best cell lines will go on to create the next round of modifications....

SciFi is betting that the only way to economically scale cultivated meat is with CRISPR, and that by making iterative tweaks they can create dependable cell lines with rich, meat-y flavor. "We have an eventual target of $1 per burger at commercial scale," March says. Once harvested, beef cells will be formulated into a blended burger that is mostly like the plant-based burgers you may already know — soy protein and coconut oil. SciFi's secret sauce is adding a small percentage of SciFi cells (5% to 20%, according to March) to reward our taste buds with the beef-y notes we may think are missing from competitors like Impossible Foods and Beyond Meat.

A 3D printer is taking home building to a new level -- literally. From a report: The enormous printer weighing more than 12 tons is creating what is believed to be the first 3D-printed, two-story home in the United States. The machine steadily hums away as it extrudes layers of concrete to build the 4,000-square-foot home in Houston. Construction will take a total of 330 hours of printing, said architect Leslie Lok, co-founder of design studio Hannah and designer of the home. "You can actually find a lot of 3D-printed buildings in many states," Lok said. "One of the things about printing a second story is you require, you know, the machine... And of course, there are other challenges: structural challenges, logistic challenges when we print a second-story building." The three-bedroom home with wooden framing is about halfway finished and is being sold to a family, who wish to remain anonymous, she said.

"We are seeing, across the gamut, products that impact our privacy, products that create cybersecurity risks, that have overarchingly long-term environmental impacts, disposable products, and flat-out just things that maybe should not exist."

That's the CEO of the how-to repair site iFixit, introducing their third annual "Worst in Show" ceremony for the products displayed at this year's CES. But the show's slogan promises it's also "calling out the most troubling trends in tech." For example, the EFF's executive director started with two warnings. First, "If it's communicating with your phone, it's generally communicating to the cloud too." But more importantly, if a product is gathering data about you and communicating with the cloud, "you have to ask yourself: is this company selling something to me, or are they selling me to other people? And this year, as in many past years at CES, it's almost impossible to tell from the products and the advertising copy around them! They're just not telling you what their actual business model is, and because of that — you don't know what's going on with your privacy."

After warning about the specific privacy implications of a urine-analyzing add-on for smart toilets, they noted there was a close runner-up for the worst privacy: the increasing number of scam products that "are basically based on the digital version of phrenology, like trying to predict your emotions based upon reading your face or other things like that. There's a whole other category of things that claim to do things that they cannot remotely do."

To judge the worst in show by environmental impact, Consumer Reports sent the Associate Director for their Product Sustainability, Research and Testing team, who chose the 55-inch portable "Displace TV" for being powered only by four lithium-ion batteries (rather than, say, a traditional power cord).

And the "worst in show" award for repairability went to the Ember Mug 2+ — a $200 travel mug "with electronics and a battery inside...designed to keep your coffee hot." Kyle Wiens, iFixit's CEO, first noted it was a product which "does not need to exist" in a world which already has equally effective double-insulated, vaccuum-insulated mugs and Thermoses. But even worse: it's battery powered, and (at least in earlier versions) that battery can't be easily removed! (If you email the company asking for support on replacing the battery, Wiens claims that "they will give you a coupon on a new, disposable coffee mug. So this is the kind of product that should not exist, doesn't need to exist, and is doing active harm to the world.

"The interesting thing is people care so much about their $200 coffee mug, the new feature is 'Find My iPhone' support. So not only is it harming the environment, it's also spying on where you're located!"

The founder of SecuRepairs.org first warned about "the vast ecosystem of smart, connected products that are running really low-quality, vulnerable software that make our persons and our homes and businesses easy targets for hackers." But for the worst in show for cybersecurity award, they then chose Roku's new Smart TV, partly because smart TVs in general "are a problematic category when it comes to cybersecurity, because they're basically surveillance devices, and they're not created with security in mind." And partly because to this day it's hard to tell if Roku has fixed or even acknowledged its past vulnerabilities — and hasn't implemented a prominent bug bounty program. "They're not alone in this. This is a problem that affects electronics makers of all different shapes and sizes at CES, and it's something that as a society, we just need to start paying a lot more attention to."

And US Pirg's "Right to Repair" campaign director gave the "Who Asked For This" award to Neutrogena's "SkinStacks" 3D printer for edible skin-nutrient gummies — which are personalized after phone-based face scans. ("Why just sell vitamins when you could also add in proprietary refills and biometic data harvesting.")

An anonymous reader quotes a report from Hackaday: Stabilizing an inverted pendulum is a classic problem in control theory, and if you've ever taken a control systems class you might remember seeing pages full of differential equations and bode diagrams just to describe its basic operation. Although this might make such a system seem terribly complicated, actually implementing all of that theory doesn't have to be difficult at all, as [Limenitis Reducta] demonstrates in his latest project. All you need is a 3D printer, some basic electronic skills and knowledge of Python. The components needed are a body, two wheels, motors to drive those wheels and some electronics. [Limenitis] demonstrates the design process in the video [here] (in Turkish, with English subtitles available) in which he draws the entire system in Fusion 360 and then proceeds to manufacture it. The body and wheels are 3D-printed, with rubber bands providing some traction to the wheels which would otherwise have difficulty on slippery surfaces.

Two stepper motors drive the wheels, controlled by a DRV8825 motor driver, while an MPU-9250 accelerometer and gyroscope unit measures the angle and acceleration of the system. The loop is closed by a Raspberry Pi Pico that implements a PID controller: another control theory classic, in which the proportional, integral and derivative parameters are tuned to adapt the control loop to the physical system in question. External inputs can be provided through a Bluetooth connection, which makes it possible to control the robot from a PC or smartphone and guide it around your living room. All design files and software are available on Limenitis' GitHub page.

Raymond Chen, writing for Microsoft DevBlogs: In the mid-1980's, Microsoft produced an expansion card for the IBM PC and PC XT, known as the Mach 10. In addition to occupying an expansion slot, it also replaced your CPU: You unplugged your old and busted 4.77 MHz 8088 CPU and plugged into the now-empty socket a special adapter that led via a ribbon cable back to the Mach 10 card. On the Mach 10 card was the new hotness: A 9.54 MHz 8086 CPU. This gave you a 2x performance upgrade for a lot less money than an IBM PC AT. The Mach 10 also came with a mouse port, so you could add a mouse without having to burn an additional expansion slot. Sidebar: The product name was stylized as MACH [PDF] in some product literature. The Mach 10 was a flop.

Undaunted, Microsoft partnered with a company called Portable Computer Support Group to produce the Mach 20, released in 1987. You probably remember the Portable Computer Support Group for their disk cache software called Lightning. The Mach 20 took the same basic idea as the Mach 10, but to the next level: As before, you unplugged your old 4.77 MHz 8088 CPU and replaced it with an adapter that led via ribbon cable to the Mach 20 card, which you plugged into an expansion slot. This time, the Mach 20 had an 8 MHz 80286 CPU, so you were really cooking with gas now. And, like the Mach 10, it had a mouse port built in. According to a review in Info World, it retailed for $495. The Mach 20 itself had room for expansion: it had an empty socket for an 80287 floating point coprocessor. One daughterboard was the Mach 20 Memory Plus Expanded Memory Option, which gave you an astonishing 3.5 megabytes of RAM, and it was high-speed RAM since it wasn't bottlenecked by the ISA bus on the main motherboard. The other daughterboard was the Mach 20 Disk Plus, which lets you connect 5 1/4 or 3 1/2 floppy drives.

A key detail is that all these expansions connected directly to the main Mach 20 board, so that they didn't consume a precious expansion slot. The IBM PC came with five expansion slots, and they were in high demand. You needed one for the hard drive controller, one for the floppy drive controller, one for the video card, one for the printer parallel port, one for the mouse. Oh no, you ran out of slots, and you haven't even gotten to installing a network card or expansion RAM yet! You could try to do some consolidation by buying so-called multifunction cards, but still, the expansion card crunch was real. But why go to all this trouble to upgrade your IBM PC to something roughly equivalent to an IBM PC AT? Why not just buy an IBM PC AT in the first place? Who would be interested in this niche upgrade product?

The story of PostScript "is a story about profound changes in human literacy," argues Silicon Valley's Computer History Museum, "as well as a story of trade secrets within source code."

And 40 years after it's creation... The Computer History Museum is excited to publicly release, for the first time, the source code for the breakthrough printing technology, PostScript. We thank Adobe, Inc. for their permission and support, and John Warnock [Adobe's 82-year-old co-founder] for championing this release....

From the start of Adobe Systems Incorporated (now Adobe, Inc.) exactly forty years ago in December 1982, the firm's cofounders envisioned a new kind of printing press — one that was fundamentally digital, using the latest advances in computing. Initial discussions by cofounders Chuck Geschke and John Warnock with computer-makers such as Digital Equipment Corporation and Apple convinced them that software was the key to the new digital printing press. Their vision: Any computer could connect with printers and typesetters via a common language to print words and images at the highest fidelity. Led by Warnock, Adobe assembled a team of skillful and creative programmers to create this new language. In addition to the two cofounders, the team included Doug Brotz, Bill Paxton, and Ed Taft. The language they created was in fact a complete programming language, named PostScript, and was released by Adobe in 1984.

By treating everything to be printed the same, in a common mathematical description, PostScript granted abilities offered nowhere else. Text and images could be scaled, rotated, and moved at will, as in the opening image to this essay. Adobe licensed PostScript to computer-makers and printer manufacturers, and the business jumped into a period of hypergrowth....

Today, most printers rely on PostScript technology either directly or through a technology that grew out of it: PDF (Portable Document Format). John Warnock championed the development of PDF in the 1990s, transforming PostScript into a technology that was safer and easier to use as the basis for digital documents, but retaining all the benefits of interoperability, fidelity, and quality. Over the decades, Adobe had developed PDF tremendously, enhancing its features, and making it a crucial standard for digital documents, printing, and for displaying graphics of all kinds on the screens from laptops to smartphones and smartwatches.

An anonymous reader quotes a report from BuzzFeed News: Joe Bowser is a computer scientist based in Port Moody, British Columbia, who has long loved Raspberry Pis. He uses the low-cost, single-board computers, which were launched in February 2012 by a UK-based company of the same name, for many of his tech projects. Those include linking the Raspberry Pi up to a 3D printer, and using the Pi to run a machine-learning demo. There's one use case that Bowser described as "the most important": using a Raspberry Pi to identify the use of IMSI catchers -- telephone eavesdropping devices that snoop on phone calls and text messages -- by law enforcement. Protesters opposing new oil pipelines happen to pass by Bowser's house regularly. He thinks cops shouldn't spy on them. So he's trying to help out the protesters using his tech knowledge. To do that, he uses Raspberry Pis. Or more accurately, he did. Bowser has forsworn using the computers ever again. He and many others are expressing their displeasure with the company on social media.

The controversy began yesterday when Raspberry Pi posted an announcement on Twitter and Mastodon: "We hired a policeman and it's going really great." The company linked to a laudatory blog post on its website announcing it had hired an ex-police officer, Toby Roberts, as its maker-in-residence. "I was a Technical Surveillance Officer for 15 years, so I built stuff to hide video, audio, and other covert gear," Roberts is quoted as saying in the post. "You really don't want your sensitive police equipment discovered, so I'd disguise it as something else, like a piece of street furniture or a household item. The variety of tools and equipment I used then really shaped what I do today." A subsection of the Raspberry Pi community expressed concern about the blase way the company presented intrusive covert surveillance. (The news caused particular ire on Mastodon, leading some to describe Roberts as the burgeoning social media platform's first "main character.") [...]

Liz Upton, Raspberry Pi's cofounder and chief marketing officer, told BuzzFeed she believes that much of the issue stems not from the hiring of the former police officer who admitted to using Raspberry Pis for covert surveillance, but instead from a picture the account posted to Mastodon a day earlier showing pigs in blankets. "We didn't put a content warning on it, because we don't put a content warning on meat," Upton said. "There were quite a few people who tried to start dogpiling on that." She also claimed that part of the vitriolic response could be because Raspberry Pi is struggling with supply chain difficulties at present, and people "were already cross." "I think what we're looking at is a dogpile that's being organized somewhere," Upton said. "There's obviously a Discord or a forum somewhere." She did not provide evidence to support that claim. "I don't think this is organic, but it's very unpleasant, and extraordinarily unpleasant for the people involved," she said. Upton claimed both Roberts and Raspberry Pi's social media manager have been doxxed and received death threats. "I am disgusted that [Raspberry Pi's] official post on Toby Roberts' hiring promotes his use of their products to surveil individuals without their consent," Matt Lewis, a Denver-based site reliability engineer, wrote via Twitter DM. "In my eyes, this behavior is completely unethical and the work Toby has done for 15 years is indefensible. I'm also upset that they have chosen to double down on this position against the community outrage."

"I think this event will mark a turning point in the organization's reputation," added Wikipedia consultant Pete Forsyth in a Twitter DM. "It's hard to see how they can recover the trust they seem to have almost willfully dismantled today."

Not everyone is downbeat about the future of the company. University of Surrey cybersecurity professor Alan Woodward called Roberts an "interesting hire" for Raspberry Pi. "His previous uses of the Pi shows just what a versatile device it is: I'm sure he's not the only one using the smallest variants to make covert devices," Woodward said. "You find that you have to be very creative to build these types of covert devices, so hopefully he can now bring that to his new role, for a wider variety of applications."

"It's not as if he is going to corrupt any of the Pis -- like all technology, it has some uses some people will object to," he said. Rather, Woodward believes "the loudest objectors are taking it a bit far. Maybe they could look at it as a glass-half-full situation: Think of the unusual innovations he might bring."

Japanese electronics and printer maker Epson announced this month that it will end the sale and distribution of laser printer hardware by 2026, citing sustainability issues. From a report: According to the company, inkjets have a "greater potential" than laser printers to make "meaningful advances" when it comes to the environment. The company already halted laser printer sales in many markets, but continued in Asia and Europe. Even though new hardware would be unavailable everywhere, Epson said it would continue to support consumers with consumables and spare parts.

"As a company we're totally committed to sustainable innovation and action, and inkjets simply use less energy and fewer consumable parts," explained Epson sales and marketing manager Koichi Kubota in canned statement. "While laser printers work by heating and fusing toner to a page, Epson's Heat-Free inkjet technology consumes less electricity by using mechanical energy to fire ink onto the page."
