[Jack]s design for a 3D-printable foaming nozzle works by mixing air with a fluid like liquid soap or hand sanitizer. This mixture gets forced through what looks like layers of fine-mesh sieve and eventually out the end by squeezing the bottle. The nozzle has no moving parts but does have an interesting structure to make this possible.

One evening, some 40 years ago, I got lost in time. I was at a performance of Schuberts String Quintet in C major. During the second movement I had the unnerving feeling that time was literally grinding to a halt. The sensation was powerful, visceral, overwhelming. It was a life-changing moment, or, as it felt at the time, a life-changing eon.

It has been my goal ever since to compose music that usurps the perceived flow of time and commandeers the sense of how time passes. Although Ive learned to manipulate subjective time, I still stand in awe of Schuberts unparalleled power. Nearly two centuries ago, the composer anticipated the neurological underpinnings of time perception that science has underscored in the past few decades.

The human brain, we have learned, adjusts and recalibrates temporal perception. Our ability to encode and decode sequential information, to integrate and segregate simultaneous signals, is fundamental to human survival. It allows us to find our place in, and navigate, our physical world. But music also demonstrates that time perception is inherently subjectiveand an integral part of our lives. For the time element in music is single, wrote Thomas Mann in his novel, The Magic Mountain. Into a section of mortal time music pours itself, thereby inexpressibly enhancing and ennobling what it fills.

Robots are not ready for the real world. Its still an achievement for autonomous robots to merely survive in the real world, which is a long way from any kind of useful generalized autonomy. Under some fairly specific constraints, autonomous robots are starting to find a few valuable niches in semistructured environments, like offices and hospitals and warehouses. But when it comes to the unstructured nature of disaster areas or human interaction, or really any situation that requires innovation and creativity, autonomous robots are often at a loss.

For the foreseeable future, this means that humans are still necessary. It doesnt mean that humans must be physically present, howeverjust that a human is in the loop somewhere. And this creates an opportunity.

In 2018, the XPrize Foundation announced a competition (sponsored by the Japanese airline ANA) to create an avatar system that can transport human presence to a remote location in real time, with the goal of developing robotic systems that could be used by humans to interact with the world anywhere with a decent Internet connection. The final event took place last November in Long Beach, Calif., where 17 teams from around the world competed for US $8 million in prize money.

While avatar systems are all able to move and interact with their environment, the Avatar XPrize competition showcased a variety of different hardware and software approaches to creating the most effective system.XPrize Foundation

NCR was the victim of the BlackCat/ALPHV ransomware gang, the attack caused an outage on the companys Aloha PoS platform.

NCR Corporation, previously known as National Cash Register, is an American software, consulting and technology company providing several professional services and electronic products. It manufactures self-service kiosks, point-of-sale terminals, automated teller machines, check processing systems, and barcode scanners.

NCR is suffering an outage on its Aloha point of sale platform since Wednesday after it was hit by a ransomware attack conducted by the BlackCat/ALPHV ransomware group.

NCR Aloha POS is a comprehensive restaurant point-of-sale and management software, the company claims it is used by more cashiers and servers than any other POS in the industry.

The company has started notifying its customers, confirming the ransomware attack:

As a valued customer of NCR Corporation, we are reaching out with additional information about a single data center outage that is impacting a limited number of ancillary Aloha applications for a subset of our hospitality customers. On April 13, we confirmed that the outage was the result of a ransomware incident. reads the notice sent by the company to the customers via email.

NCR notified law enforcement and engaged third-party cybersecurity experts to investigate the incident and determine the scope of the attack.

The company pointed out that restaurants impacted are still able to serve their customers and that the incident only impacted a specific functionality.

Only specific functionality is impaired. There is no impact to payment applications or on-premises systems. continues the notice.

Usually, the problem comes before the solution, but for [Stavros], the opposite happened. A 4.7 E-Ink screen with integrated battery management and ESP32 caught his eye, and he bought it and started thinking about what he wanted to do with it. The Timeframe (hackaday.io link as well) is a sleek desk calendar based around the integrated e-ink screen.

[Stavros] found the devices MicroPython support was a little lackluster, and often failed to draw. He found a Platform.io project that used an older but modified library for driving the e-ink display which worked quite well. However, the older library didnt support portrait orientation or other niceties. Rather than try and create something complex in C, he moved the complexity to a server environment he knew more about. With the help of CoPilot, he got some code that would wake up the ESP32 every half hour, download an image from a server, and then display it. A Python script uses a headless browser to visit Google Calendar, resize the window, take a screenshot, and then upload it.

The hardest part of the exercise was getting authentication with Google working reliably. A white sleek 3d printed case wraps the whole affair in an...

The lithium-ion battery isnt going anywhere soon. Thats what M. Stanley Whittingham, the Nobel laureate who created the first rechargeable lithium-ion battery some 50 years ago, told attendees of the SLAC-Stanford Battery Research Center Launch Symposium on Thursday. The new organization aims to bridge gaps between organizations that research, manufacture, and deploy large-scale energy storage systems.

M. Stanley Whittingham

Its going to be at least five-to-ten years before any alternative technologies can compete on cost with lithium-ion technology, Whittingham predicted.

Granted that this technology remains the incumbent for some time to come, Whittingham has concernsbig concernsabout how the world makes and uses these energy storage devices. Here are the big issues he worries about:

Manufacturing

Its ridiculous that manufacturing technologies havent changed in 30 years, Whittingham says. We need to reduce the 60 to 80 kilowatt hours) of electricity it takes to produce a one kWh battery, he says. Weve got to find new manufacturing technologies.

Recycling

Whittingham is also worried about recycling technologies. Hes encouraged that facilities to recycle lithium-ion batteries are being built around the world, but he adds, We need to make sure they are clean.

Mining

The supply chain for the minerals used in battery manufacturing in the first place also need work. We need regional supply chains, Whittingham says. And we need to look at clean mining with clean energy.

Heavy Metals

Given that some components of a lithium-ion batterys traditional chemistry are inherently toxic, they must be engineered out of the device as soon as possible, Whittingham says. He put it bluntly: Co...

Do you know why humanity still doesnt have colonies on the Moon or Mars? Because the big companies that mightve invested their money in building the said colonies are not sure when theyll get their investments back and start making a solid profit. Well, at least thats one of the reasons.

But the cheaper space flights will get and further the technologies that can help cost-efficiently settle on other planets will develop, the more countries, billionaires, tech giants, startups and institutions will get into the space race, whose finish line is right on the Red Planet. Why are they reluctant to do this? Are they afraid of future cataclysms? Do they know something we dont? Are they dreaming of claiming the title of pioneers?

Ivan Sutherland has blazed a truly unique trail through computing over the past six decades. One of the most influential figures in the story of computing, he helped to open new pathways for others to explore and dramatically extend: interactive computer graphics, virtual reality, 3D computer graphics, and asynchronous systems, to name but a few.

The Computer History Museum recently made public its two-part oral history with Sutherland. These interviews present a wonderful opportunity to learn more about Sutherlands life in computing, in his own words. The interview transcripts can be downloaded here and here. And the two-part video of the interview is available here and here.

Bob Sproull, a lifelong colleague of Sutherland and himself a major figure in computing, served as instigator, interviewer, and editor for these oral histories, and he involved me, Marc Weber, and Jim Waldo in the effort. The Museum is making this oral history interview public during the 60th anniversary year of Sutherlands breakthrough in interactive computer graphics, the program Sketchpad, for which he earned his Ph.D. from MIT in 1963.

Ivan Sutherlands Unique Perspective

There is a phrase, popular in 17th and 18th century England, that occurs to me when thinking about Ivan Sutherland: A man of many parts. The phrase refers to an individual who had made serious contributions to a domain, while also possessing multiple, and often diverse, talents and pursuits. The description fits Sutherland well, although it also misses something important: There is a commonality in his many accomplishments, a shared wellspring for his many parts.

To get at this wellspring, start with geometry. From his youth, Sutherland possessed an unusually keen spatial, geometric intuition. In his mind and at his hands, he experienced an immediacy in perceiving how things fit and worked together. Perspective drawing involves a set of techniques to represent a three-dimensional scene on the two-dimensional plane of a sheet of paper or a stretch of canvas. These renderings can proceed in different ways, determined by the number of vanishing points employed. Together the v...

Machine learning has boosted the resolution of an image produced by Event Horizon Telescope data captured six years ago:

Using machine learning, a team of researchers has enhanced the first image ever taken of a distant black hole. Importantly, the newly updated image shows the full resolution of the telescope array for the very first time.

[...] The machine learning model has sharpened the otherwise blurry image of black hole M87, showcasing the utility of machine learning models in improving radio telescope images. The team's research was published today in the Astrophysical Journal Letters.

"Approximately four years after the first horizon-scale image of a black hole was unveiled by EHT in 2019, we have marked another milestone, producing an image that utilizes the full resolution of the array for the first time," said Dimitrios Psaltis, a researcher at Georgia Tech and a member of the EHT collaboration, in an Institute for Advanced Study release. "The new machine learning techniques that we have developed provide a golden opportunity for our collective work to understand black hole physics."

[...] But even using radio telescopes around the world doesn't give astronomers a complete view of the black hole; by incorporating a machine learning technique called PRIMO, the collaboration was able to improve the array's resolution. What appeared a bulbous, orange doughnut in a 2019 image has now taken on the delicate, thin circle of The One Ring.

Microsoft warns of a new Remcos RAT campaign targeting US accounting and tax return preparation firms ahead of Tax Day.

Ahead of the U.S. Tax Day, Microsoft has observed a new Remcos RAT campaign targeting US accounting and tax return preparation firms. The phishing attacks began in February 2023, the IT giant reported.

Remcos is a legitimate remote monitoring and surveillance software developed by the company BreakingSecurity.

In 2021, CISA added Remcos to the list of top malware strains due to its use in mass phishing attacks using COVID-19 pandemic themes targeting businesses and individuals.

The recent campaign exclusively aims at organizations that deal with tax preparation, financial services, CPA and accounting firms, and professional service firms dealing in bookkeeping and tax.

Crooks use lures masquerading as tax documentation sent by a client. The message contains a link that points to a legitimate file hosting site where the cybercriminals have uploaded Windows shortcut (.LNK) files.

Upon clicking on the file, a malicious file is fetched from a domain under the control of the attacker which leads to the installation of the Remcos RAT.

What we have observed is that the link in the phishing email points to Amazon Web Services click tracking service at awstrack[.]me. The initial link then redirects the target to a ZIP file hosted on legitimate file-sharing service spaces[.]hightail[.]com. The ZIP file contains LNK files that act as Windows shortcuts to other files. reads the report published by Microsoft. The LNK files make web requests to actor-controlled domains...

Although neutrinos are exceedingly common, their near-massless configuration means that their presence is rather ephemeral. Despite billions of them radiating every second towards Earth from sources like our Sun, most of them zip through our bodies and this very planet without ever interacting with either. This property is also what makes studying these particles that are so fundamental to our understanding so complicated. Fortunately recently published results by researchers behind the SNO+ neutrino detector project shows that we may see a significant bump in our neutrino detection sensitivity.

[CuriousMarc] has a pile of 8-inch drives, all marked bad. You cant just pop over to the computer store and buy a new one these days, so it was off to the repair bench. Although the target drive would do a quick seek,  once it was in use, it just kind of shut down. So [Marc] started sending low-level commands to the device to see if he could isolate the fault. You can watch the whole adventure in the video below.

Using a breakout board, he was able to monitor and exercise all the pins going into the floppy. A quick study of the schematics, and connection to the scope were all [Marc] needed to build some theories of what was happening.

One of the theories was that the head amplifier was disabled, but it turned out to be fine. After several other dead ends, he finally found a broken spring and came up with a creative repair for it. But there was still no clear reason why the drive wouldnt work. By process of elimination, he started to suspect an array of diodes used for switching, but again, it was another dead end.

Luckily, he had one working drive, so he could compare things between them. He found a strange voltage difference. Turns out the old advice of checking power first might have paid off here. One of the voltage regulator ICs was dead. In all fairness, there are two 12V power supplies and he had checked one of them but had missed the second supply.  This supply is only used for head bias which switches the diodes he h...

Writers and publishers face an existential threat from AI: time to embrace the true fans model:

Walled Culture has written several times about the major impact that generative AI will have on the copyright landscape. More specifically, these systems, which can create quickly and cheaply written material on any topic and in any style, are likely to threaten the publishing industry in profound ways. Exactly how is spelled out in this great post by Suw Charman-Anderson on her Word Count blog. The key point is that large language models (LLMs) are able to generate huge quantities of material. The fact that much of it is poorly written makes things worse, because it becomes harder to find the good stuff[.]

[...] One obvious approach is to try to use AI against AI. That is, to employ automated vetting systems to weed out the obvious rubbish. That will lead to an expensive arms race between competing AI software, with unsatisfactory results for publishers and creators. If anything, it will only cause LLMs to become better and to produce material even faster in an attempt to fool or simply overwhelm the vetting AIs.

The real solution is to move to an entirely different business model, which is based on the unique connection between human creators and their fans. The true fans approach has been discussed here many times in other contexts, and once more reveals itself as resilient in the face of change brought about by rapidly-advancing digital technologies.

U.S. DARPAs Robotic Autonomy in Complex Environments with Resiliency (RACER) program recently conducted its third experiment to assess the performance of off-road unmanned vehicles. These test runs, conducted March 1227, included the first with completely uninhabited RACER Fleet Vehicles (RFVs), with a safety operator overseeing in a supporting chase vehicle. The goal of the RACER program is to demonstrate autonomous movement of combat-scale vehicles in complex, mission-relevant off-road environments that are significantly more unpredictable than on-road conditions. The multiple courses were in the challenging and unforgiving terrain of the Mojave Desert at the U.S. Armys National Training Center (NTC) in Ft. Irwin, California. As at the previous events, teams from Carnegie Mellon University, NASAs Jet Propulsion Laboratory, and the University of Washington participated. This completed the projects first phase.

We provided the performers RACER fleet vehicles with common performance, sensing, and compute. This enables us to evaluate the performance of the performer team autonomy software in similar environments and compare it to human performance, said Young. During this latest experiment, we continued to push vehicle limits in perceiving the environments to greater distances, enabling further increase in speeds and better adaptation to newly encountered environmental conditions that will continue into RACERs next phase.

At Experiment Three, we successfully demonstrated significant improvements in our off-road speeds while simultaneously reducing any interaction with the vehicle during test runs. We were also honored to have representatives from the Army and Marine Corps at the experiment to facilitate transition of technologies developed in RACER to future service unmanned initiatives and concepts, said Stuart Young, RACER program manager in DARPAs Tactical Technology Office.

Vrgineers and Advanced Realtime Tracking demonstrate the combination of XTAL 3 headset and SMARTTRACK3/M in a mixed reality pilot trainer. The partnership between these two technological companies started in 2018. At IT2EC 2023 in Rotterdam, the integrated SMARTTRACK3/M into an F-35-like Classroom Trainer manufactured and delivered to USAF and RAF will be for display. This unique combination of the latest ART infrared all-in-one hardware and Vrgineers algorithms for cockpit motion compensation creates an unseen immersion for every mixed reality training. One of the challenges in next-generation pilot training using virtual technology and motion platforms is the alignment of the pilots position in the cockpit. By overcoming this issue, the simulator industry is moving forward to eliminate the disadvantages of simulated training.

We are continuously working on removing the technological challenges of modern simulators, one of which is caused by front-facing camera position distance from users eyes. We are developing advanced algorithms for motion compensation to minimize the shift between virtual and physical scene, making experience realistic. The durability and compact size of SMARTTRACK3/M, which was optimized for using in cockpits, allows us as training device integrator to make it a comprehensive part of a simulation, says Marek Polcak, CEO of Vrgineers.

This is the application SMARTTRACK3/M was designed for., We have taken the proven hardware from the SMARTTRACK3 and adapted it to the limited space available. As a result, we have the precision and the reliability of a seasoned system in a form factor fitting to simulator cockpits says Andreas Werner, business development manager for simulations at ART.

GPT-5 isnt being developed, but who cares when GPT-4 isnt yet understood.

Despite the availability of imaging-based and mass-spectrometry-based methods for spatial proteomics, a key challenge remains connecting images with single-cell-resolution protein abundance measurements. Deep Visual Proteomics (DVP), a recently introduced method, combines artificial-intelligence-driven image analysis of cellular phenotypes with automated single-cell or single-nucleus laser microdissection and ultra-high-sensitivity mass spectrometry. DVP links protein abundance to complex cellular or subcellular phenotypes while preserving spatial context.

Real-time flight data used to be something that was only available to air traffic controllers, hunched over radar scopes in darkened rooms watching the comings and goings of flights as glowing phosphor traces on their screens. But that was then; now, flight tracking is as simple as pulling up a web page. But wheres the fun in that?

To bring some of that old-school feel to his flight tracking, [Jarrett Cigainero] has been working on this ADS-B scope that uses a real radar CRT. As you can imagine, this project is pretty complex, starting with driving the 5FP7 CRT, a 5 round-face tube with a long-persistence P7-type phosphor. The tube needs about 7 kV for the anode, which is delivered via a homebrew power supply complete with a custom flyback transformer. Theres also a lot going on with the X-Y deflection amps and beam intensity control.

You don't need alien asteroids, you just need a hydrogen-rich atmosphere and liquid hot magma:

A new research model shows that Earth's oceans could have formed from interactions between a hydrogen-rich early atmosphere and oxygen within the planet's magma.

The study from the multi-institution AETHER project also demonstrates why Earth's core is lighter than it should be, owing to the presence of gaseous hydrogen.

Edward Young, professor at the University of California Los Angeles, and colleagues propose that one of the protoplanets involved in the formation of Earth was heavier than thought. By maximizing its size to more than a fifth or third of Earth, the researchers show there would have been enough gravity to make the hydrogen-rich atmosphere hang around long enough to interact with the magma ocean, according to a paper published in Nature this week.

Prevailing theories explaining the abundance of water on Earth oceans make up around 70 percent of the planet's surface depend on the impacts of water-carrying asteroids.

[...] In a statement coinciding with the publication, co-author Anat Shahar, staff scientist and deputy for Research Advancement Earth and Planets Laboratory at Carnegie Science, said the inspiration for the new model came from studies of planets forming outside the solar system.

When the IBM PC first came out, it was little more than a toy. The serious people had Sun or Apollo workstations. These ran Unix, and had nice (for the day) displays and network connections. They were also expensive, especially considering what you got. But now, QEMU can let you relive the glory days of the old Sun workstations by booting SunOS 4 (AKA Solaris 1.1.2) on your PC today. [John Millikin] shows you how in step-by-step detail.

Theres little doubt your PC has enough power to pull it off. The SUN-3 introduced in 1985 might have 8MB or 16MB of RAM and a 16.67 MHz CPU. In 1985, an 3/75 (which, admittedly, had a Motorola CPU and not a SPARC CPU) with 4MB of RAM and a monochrome monitor cost almost $16,000, and that didnt include software or the network adapter. Youd need that network adapter to boot off the network, too, unless you sprung another $6,000 for a 71 MB disk.  The SPARCstation 1 showed up around 1989 and ran from $9,000 to $20,000, depending on what you needed.

[John] points out that, unlike a modern PC, SunOS ran on very tightly-controlled hardware, so it is pretty fussy about some things being just right. Apparently, QEMU could not boot the OS without some workarounds until recently, but the setup [John] outlines seems straightforward.

In its heyday, the machine would get network configuration from a RARP and NIS server, but those have long given way to more modern standards like DHCP. Not...
