WWDC 2026 is shaping up to be all about on-device AI

Published

on

Apple’s big yearly software event looks set to focus a lot on on-device AI, with reports suggesting the company’s in-house chip architecture will give it a key advantage over rivals.

WWDC 2026 kicks off on 9 June, with iOS 27 for iPhone and software updates for iPad, Mac, Apple Watch, and Apple Vision Pro all expected to be previewed at the event, and AI is widely anticipated to be integrated into pretty much every new feature Apple introduces.

The shift toward on-device processing addresses a core limitation of most AI implementations, where queries travel to remote data centres and back before a result reaches the user, introducing latency that depends entirely on network quality and connection speed.

Apple’s silicon lineup, which powers everything from the iPhone through to the Mac, carries enough processing headroom to handle AI inference locally, cutting out that round trip entirely and keeping the workload on the device itself.

Privacy and cost implications

That architectural difference carries particular weight on the privacy front, since on-device processing means user data never leaves the hardware, removing the exposure point that cloud-based AI systems create when queries pass through third-party infrastructure.

Running AI on-device also removes the per-query cost of data centre processing, a significant consideration as Apple scales Apple Intelligence features across hundreds of millions of active devices worldwide.

According to The Information, Apple is working with a version of Google’s Gemini model as a reference point for training a smaller, locally-capable model, and the company is also reportedly evaluating acquisitions of firms with expertise in models optimised for on-device deployment.

Whatever Apple announces on 9 June, the features themselves will not reach users immediately; software updates across all platforms are expected to follow the standard testing cycle ahead of a likely September release.

An answer to the datacenter energy crisis

Published

on

Partner Content This
year, the global build-out of datacenters has become impossible to
ignore, with the debate spilling into national media, local
newspapers, and community council meetings alike. From Arkansas to
Southern California, Nevada, Pennsylvania, West Virginia, and most
recently Box Elder, Utah, communities are weighing the economic
promise of datacenter expansion against mounting concerns over
energy, infrastructure, and residential impact. The same dynamic is
playing out in the UK, where OpenAI’s “Stargate UK” project
has been partly shelved
amid energy consumption concerns and regulatory pressure.

Drop media element here …

A typical new hyperscale datacenter can face grid-connection
bottlenecks of up to seven
years
in certain markets, well before the necessary
transmission, substations, generation capacity, and transformers are
in place. McKinsey, meanwhile, estimates that global datacenter
spending could reach $7
trillion by 2030
– a figure comparable to the size of a
top-12 global economy.

AI intelligence at scale now dominates enterprise strategy and
global politics because the promise of the technology is matched only
by the infrastructure required to deliver it. Energy consumption is
unavoidable in this new world, and the bet enterprise leaders are
making is that the value AI creates will outstrip the cost of the
power feeding it. That trade-off has produced a new equation for
executives: intelligence
per watt
.

Is your agentic ambition constrained by energy?

AI-driven datacenters already account for
roughly 1.5 percent of global electricity consumption, and the IEA
expects that demand to more
than double
by 2030, approaching three percent of global
electricity use. That’s more than many major industrial sectors,
including agriculture.

The pressure will compound over the next three years, with IDC
projecting onebillion
agents running 217 billion daily actions
by 2029. From
Seattle to Barnsley in the UK, the race to build more datacenters
close to energy sources is now a daily occurrence.

If the right datacenter, grid, and power infrastructure for the
first billion agents takes up to seven years to build, supporting
two, three, or even eight billion agents implies timelines the
industry has yet to cost. The mismatch between enterprise intent and
energy capacity is widening.

For enterprise leaders, this is a defining moment of decision.
With 95
percent
of global enterprises intending to become their
own AI and data platforms in less than 780 days, AI, data, and energy
can no longer be treated as separate priorities; they are now
interconnected parts of a single platform strategy. The harder
question is how executives can pursue those AI ambitions while
managing energy efficiently at agentic scale.

BFSI might be showing us the way forward

Banking, financial services, and insurance
(BFSI) enterprises have traditionally invested more heavily in
technology than any other major sector. McKinsey estimates banking IT
spending typically runs at between
six and 12 percent of revenue
, compared with 3.75 percent
to five percent for the next-highest sector.

The pressure to deliver new technology value, particularly through
AI and agentic systems, is creating an operating language shared by
CIOs, CTOs, and business leaders alike. AI and data are increasingly
framed as the new competitive moat, yet the energy costs associated
with maintaining that moat introduce a fresh dynamic into technology
decision-making.

The 13
percent of global enterprises
winning with AI and agentic
systems are more likely to build their data strategies around
control, efficiency, and sustainability. The common pattern is
repatriation: pulling AI and data out of single-hyperscaler silos and
into their own control planes, where they can govern and manage
information across clouds, on-premises environments, and systems they
own.

The pattern recurs among agentic AI leaders across EMEA, North
America, Singapore, and Japan. The principle is straightforward:
bring AI to the data, because the two must work together across the
front lines and back offices of the business rather than operating as
separate concerns.

Advertisement

That logic explains why BFSI leaders such as Wells Fargo,
Mastercard, HSBC, JPMorgan Chase, Bank of America, Citigroup, Goldman
Sachs, BNP Paribas, ING, Crédit Agricole, UBS, and NatWest have made
public carbon-neutrality commitments alongside ambitious plans to
become their own sovereign AI and data platforms.

AI and data sovereignty in Postgres wins on OpEx, environment, and
ROI

Agents operate at the data layer, which
means energy must be managed at the same layer, since this is where
much of the work happens. The alternative is the equivalent of
turning on the heat while leaving every window open in the middle of
winter. Only by controlling the data layer, agents, and broader data
estate can enterprises build the foundation for managing energy
consumption.

Energy efficiency has to begin where enterprise operations already
run, which is why PostgreSQL®, the world’s most widely used database
among developers, is well suited to the challenge. EDB
Postgres AI
is built specifically to address the
energy-intensive nature of modern datacenters by improving database
and AI efficiency at the point where workloads execute.

By shrinking core usage requirements and tightening data-intensive
agentic operations such as search, retrieval, and vector indexing,
EDB Postgres AI can cut datacenter energy consumption by up to 81
percent and reduce emissions by as
much as 87 percent
.

Advertisement

The ambition to become an AI and data platform carries one
foundational requirement: AI and data sovereignty. Organizations that
adopt this model not only achieve 5x
ROI and deploy 2x more AI and agentic AI systems
; they
also gain more control, greater efficiency, and a smarter way to
design and operate datacenters for the agentic era.

The formula for success is sovereignty in Postgres — the most
practical path to achieving more intelligence per watt.

An Atic Atac Minimap For The ZX Spectrum

Published

on

The use of modern microcontrollers as add-on peripherals for 1980s home computers has delivered significant benefits and capabilities unimaginable in the days when those machines were new. A great example come from [Happy Little Diodes], who’s using a Pi Pico based peripheral for a Sinclair ZX Spectrum to provide something that looks far more modern, a hardware minimap for the iconic Spectrum game, Atic Atac.

The ZX expansion port provides all the bus signals from the Z80 microprocessor, and the peripheral uses a latch to capture Spectrum memory writes. Because the game’s operation is well known it can easily watch out for updates to the in-memory variable that contains the game room ID. It’s then a case of drawing the map with the player centered on the room the are in, for a much more 21st century game interface component.

Having been around when both the ZX and this game were new, we like this add-on, a lot. We can imagine it could relatively easily support other games, too.

Autodesk buys MaintainX for $3.6bn to push from design into operations

Published

on

Autodesk has spent four decades selling the software that engineers and architects use to design buildings, factories and machines. With its latest acquisition, it is buying its way into what happens after those things are built.

The company has agreed to acquire MaintainX, a maintenance and operations platform, for about $3.6 billion in cash.

The deal, announced on 28 May, is an all-cash transaction Autodesk plans to fund with cash on hand and new debt. Closing is targeted for as early as 3 August, subject to regulatory and customary conditions.

Alongside the headline price, Autodesk said it would issue $150 million in restricted stock to MaintainX employees, the standard retention sweetener that signals the buyer wants the team, not just the product.

Advertisement

MaintainX is the kind of company that is invisible until something breaks. Founded in San Francisco in 2018 and led by chief executive Chris Turlica, it makes mobile-first maintenance software, a modern take on the computerised maintenance management systems, or CMMS, that factories and facilities use to track work orders, assets and repairs.

Advertisement

More than 500,000 frontline workers use it, and the company was last valued at around $2.5 billion privately, on annual recurring revenue reported near $115 million.

At roughly $3.6 billion, Autodesk is paying a clear premium to that last private mark, which is the going rate when a strategic buyer wants a category leader rather than a turnaround.

The number also looks large against MaintainX’s revenue, the kind of multiple that only makes sense if the buyer is pricing the strategic fit rather than the current financials.

That fit is the whole rationale. Autodesk frames its strategy as converging “design, make and operate,” the idea that data should flow continuously from the moment something is designed to the years it spends in service. It has the design and the make; operations was the gap.

Advertisement

MaintainX slots into a new division Autodesk is calling Autodesk Operations Solutions, giving it a foothold in the daily work of the maintenance teams who keep its customers’ physical assets alive.

There is an AI logic underneath the org chart. Maintenance data, every work order, every breakdown, every part replaced, is exactly the kind of structured operational record that trains useful predictive models, and Autodesk has been pushing its own generative-AI design tools.

Owning the operate layer gives it a data stream it did not have, at a moment when every enterprise-software company is racing to turn its workflows into AI features.

For MaintainX, a $3.6bn cash exit is a clean outcome for its backers and a fast one for a company not yet a decade old.

Advertisement

For Autodesk, the harder work begins after August: integrating a mobile-first frontline product into a design-software giant, and proving that “design, make and operate” is a platform customers will buy as one thing rather than a slide that explains an acquisition.

PS4 and Xbox One players are getting booted from Call of Duty Warzone soon

Published

on

Call of Duty players on previous-generation consoles can’t seem to catch a break. First, Activision announced that the next Call of Duty, which we now know is Call of Duty: Modern Warfare 4, will not be released on PS4 and Xbox One. Now, the company is also taking Call of Duty: Warzone away from both older consoles.

The publisher has confirmed that Warzone support on PS4 and Xbox One will be reduced in stages before ending later this year. The first step begins on June 4, when Warzone will be removed from the PlayStation 4 and Xbox One digital storefronts. After that, new downloads will no longer be available on either platform.

Warzone’s last-gen exit starts in June

Players who already have Warzone in their library will still be able to install and play the game for a limited time. Activision says the game will remain playable on PS4 and Xbox One through the end of Season 06 for Call of Duty: Black Ops 7.

The next major change arrives on June 25, when the Warzone in-game store will be removed from both last-gen versions. COD Points can still be redeemed in the store until then, and gameplay will continue to count toward Battle Pass progression. Players without the paid Battle Pass can still unlock free-tier rewards, including new weapons, during the remaining Black Ops 7 seasons.

The final cutoff comes with Modern Warfare 4 Season 1. Once that season begins, Warzone will no longer be playable on PS4 or Xbox One.

Advertisement

Upgrading may sting for PS4 holdouts

For PlayStation players, the timing is awkward. Sony’s Days of Play 2026 sale is live, but the PS5 console itself does not appear to be getting a discount. The upside is that players who do upgrade can still pick up discounted PS5 games, accessories, and PlayStation Plus memberships while the sale runs through June 10.

Activision says players will not lose their Warzone progress if they move to PS5, Xbox Series X|S, or PC using the same linked Activision account. Items bought with COD Points will also carry over. However, unused COD Points stay tied to the same console family, so PS4 players can use them on PS5, and Xbox One players can use them on Xbox Series X|S.

Warzone gave PS4 and Xbox One players a long runway after the current-gen consoles arrived. That runway is now almost over, and anyone who wants to keep playing Call of Duty’s battle royale after this season will need to move to newer hardware soon.

This Week In Security: Ubiquiti Fixes, And FreeBSD Joins The Club You Don’t Want To Join

Published

on

Ubiquiti released a new security bulletin detailing fixes for six security issues, including one rated 9.1 (critical) and one scoring a perfect 10.0 on the CVE risk scale.

The vulnerabilities range from path traversal revealing configuration files (escaping from the web server by requesting a path like “../../../../../etc/passwd” for instance), to command injection (running arbitrary shell commands on the system), and actually changing device configurations. Some of the reported vulnerabilities require an account on the management server, but some only require network access .

Fortunately, all of the vulnerabilities require access to the network in the first place to exploit – but this could include access to open guest networks as well as trusted users. If you run Ubiquti or UniFi equipment, chances are the automatic update function has already integrated the fixes, but make sure to check the advisory to see if you’re impacted and update accordingly!

FreeBSD Root Exploit

FatGid lets FreeBSD join the fun of kernel exploits to gain root.

Advertisement

The FatGid vulnerability doesn’t require any manipulation of disk cache; instead it is a direct kernel stack overflow in a system call. The kernel miscalculates the size of a variable as 8 bytes instead of 4, which when used later interacting with a user buffer allows the stack overflow.

Like the recent spate of Linux local privilege escalation attacks, this requires the attacker to already have an account on the system or the ability to run arbitrary programs, but remember that any bug in network services which allows command execution gets you there, so if you run network exposed FreeBSD, it’s time to update!

Kali365 Phishing-as-a-Service

Phishing-as-a-service platforms have been gaining traction, allowing criminals to automate targeting users with crafted lures. The FBI has issued a warning about the Kali365 service in particular.

Kali365 targets credentials for Microsoft 365 accounts by directing users to the official Microsoft portal for linking additional devices to the account, attaching an attacker device directly to the user identity. Alternatively, the framework steals credentials by directing the user through a hostile service which presents a false login page which captures browser sessions along with authentication cookies and tokens once the user answers the fake multi-factor login prompts.

Advertisement

Automating the phishing process lowers the bar for the skill level needed to create authentic-looking lures and makes it simpler for criminal groups to attack large numbers of users; Phishing-as-a-service groups operate as companies offering customer support, tracking dashboards, and pre-made phishing templates.

Glassworm Botnet Takedown

CrowdStrike, Google, and the ShadowServer Foundation have done a coordinated takedown of the infrastructure used by the Glassworm supply-chain botnet.

Glassworm has been mentioned previously; it is one of several major worms infecting the open source package supply chain repositories like NPM and PyPi or the Visual Studio extension repository. Once a victim installs a compromised package or extension, the Glassworm trojan steals any saved authentication tokens for package repositories, GitHub accounts, AI services, and any SSH keys found, and begins the stage two infection. Using the stolen credentials, the worm infects any GitHub workflows, packages, and extensions the user has access to, and installs a remote-access trojan which waits for further commands.

Glassworm used a complex control server structure including blockchain memos, BitTorrent files, and public Google Calendar entries, but the coalition of companies was able to interrupt all control channels simultaneously. Hard-coded aspects of the worm will continue to function, but all behavior which requires downloading payloads from the control servers has been disrupted.

This isn’t the first time multiple Internet companies have coordinated to take down malware, but it’s always good to see action against threats which have been decimating the package repository infrastructure lately.

TechCrunch Spyware Avoidance

On the positive side of things, TechCrunch has an article about modern features to protect users against spyware. If this isn’t news to you, there’s still almost certainly someone in your life who will benefit from a user-friendly write up of best practices!

Both major commercial mobile platforms (iOS and Android) offer advanced protection features which are minimally invasive. For users who are likely to be higher targets of spyware like journalists, lawyers, and human rights activists, or simply those who are worried, these features offer real protection.

The features explained in the article include Apple’s Lockdown mode, Androids Advanced protection mode, and WhatsApp specific application settings, all of which work to reduce common attack surfaces for devices. The advanced security modes typically have minor impacts on performance and battery life due to disabling optimization features which introduce additional complexity and attack surfaces (such as just-in-time compilation of JavaScript code into native instructions.). When situations call for an abundance of caution, a few percent of battery life daily is a reasonable compromise.

Microsoft Bans NightmareEclipse

An exploit researcher known only as “NightmareEclipse” has been featured here several times in the past months already. Showing intense frustration with their experience with the administrators of the Microsoft security bug bounty program, they have taken to releasing zero-day exploits against Windows, often coinciding with Patch Tuesday (clearly no accident; by releasing a new exploit on the same day as the Microsoft patch set, it’s unlikely to be fixed before the next months Patch Tuesday at the earliest). Previous exploits released by NightmareEclipse include BlueSun and RedHammer (local user to Windows SYSTEM privilege escalation), UnDefend to disable Windows Defender, and YellowKey which unlocks BitLocker drives using a collection of nothing more than magically named files.

Toms Hardware reports that Microsoft has disabled the researchers GitHub accounts (GitHub being owned by Microsoft has long been a point of concern for security researchers who find vulnerabilities in Microsoft products), as well as the actual Microsoft account used by the researcher.

While it’s certainly within the terms of service of Microsoft and GitHub that accounts may be terminated, the optics are particularly poor in this case, given the confusion around the initial interactions which led the researchers original anger. NightmareEclipse has moved their example code repositories to GitLab in the mean time, and promises Microsoft that “I will make sure your bones are shattered on July 14”, implying there will be additional releases (on, you guessed it, what looks like another Patch Tuesday).

Further clouding the issue, an official Microsoft statement indicates they are attempting to bring criminal (not just civil) charges against researchers who do not cooperate with the Microsoft disclosure policies, a stance which will certainly in no way exacerbate the situation.

Fingerprinting Devices by SSD

Dan Goodin at Ars Technica highlights a new paper on fingerprinting users via SSD disk performance, using just standard JavaScript.

The modern web is a hellscape of user tracking, and this attack, dubbed FROST, highlights another technique for identifying unique devices and user patterns based entirely on hardware behavior. By generating a large file using local browser storage via OPFS (origin private file system, an API for JavaScript to create raw files inside the browser storage area) and continually reading and writing data while monitoring the performance, a web page is able to monitor the disk access performance of the device.

Using a neural network trained on timing data, researchers say they are able to determine what apps may be running on the computer alongside the browser – and sometimes even what other websites are being viewed, based solely on the delays in disk IO caused by other applications and websites accessing the SSD. The paper will be presented in July, with researchers saying that the neural network can be trained to recognize “any system which reliably generates SSD accesses”.

Advertisement

Likely, browser developers can mitigate FROST by decreasing the performance of file operations in the OPFS API so that the performance data lacks the fidelity needed to derive user behavior.

FROST is a “side channel attack”; by monitoring one set of characteristics, side channel attacks are able to infer other system behaviors. Side channel attacks can be incredibly subtle and difficult to predict: Another side channel attack method has been to use extremely fine-grained monitoring of the power consumption of a device to derive encryption keys, predicting the CPU instructions and values based on the amount of power used to set the internal registers.

Improving Memory Safety in C#

Programming languages have been moving towards stronger default memory models, making programs more secure by default by eliminating behaviors which are commonly exploitable. Using a memory-safe language does not prevent logic errors or other security issues, but can still help by eliminating common mistakes.

Microsoft has posted an extensive article about new enhancements for C# in .NET 11. Borrowing in many ways (that’s a programming joke) from the Rust memory model, C# 16 will add additional memory enforcement and object lifetime, detecting when memory is no longer available and preventing invalid memory accesses on expired objects, with the goal of eliminating use-after-free memory corruption and attacks.

Advertisement

C# 16 will also increase the meaning of the “unsafe” keyword, a mechanism introduced in C# 1.0 and since heavily adopted by newer languages such as Rust and Swift. Code marked as unsafe in C# 16 is able to bypass the stricter memory model, but all code referencing it must also be marked as unsafe. Making unsafe code more difficult to use increases the overall friction of doing things the dangerous way, while clearly marking code which is higher risk.

There are few magic bullets for secure programming, but reducing the ways a programmer can make simple mistakes can be a big win.

When Is An Apple Laptop Not A Macbook? When It’s An Apple II

Published

on

Do you remember, some years ago, when that brand-new 8086-based laptop hit the shelves? Great for PC lovers, but not so fun for those on the fruitier side of the street. Well, the same Chinese firm that brought us the Book8086 are back, this time with an ‘Apple’ Laptop that is decidedly not a MacBook– the Book II is a dual-processor Apple II clone in a laptop form factor.

… but just look at all those DIPs on the inside. Authentically retro!

Dual processor? On an Apple II? It wasn’t that uncommon, back in the day — that’s what the Z80 softcard was, after all: a second processor that let you run CP/M and associated business applications, and this one has it built-in. It also has the 80-column video card, a second floppy controller, a printer interface, and a 16 kB ROM card for languages. That leaves two of the Apple’s expansion slots available, one of which is broken out externally on the back of the laptop, along with the printer and floppy ports.

Useful? Probably no more so than the NEC V20-based PC version. Still, those did find buyers and we have no doubt that this new laptop will, too. Especially since with the right expansion card, you might get this machine running DOS as well. Of course if you don’t feel like shelling out the quid or running an emulator, you can always roll your own Apple II on an FPGA.

Thanks to [Stephen Walters] for the tip! We usually steer clear of product announcements like this, but [Stephen] figured we’d be interested in this one since we covered the then-new retro PC versions way back in 2023.

This Soft Clock Drives Its Display With Pneumatic Logic

Published

on

Electrons are great. We use them to move vehicles, illuminate cities, and, of course, compute. But computation is not confined to the world of electronics. And shifting to alternative nonelectronic realms can unlock unique advantages: Photonic chips, for instance, process information with light while generating little heat. Another compelling alternative is fluidics, which uses pressurized gases or liquids to build logic circuits. Pioneered in the 1960s but sidelined by microchips, the field reemerged in the 1990s as “microfluidics.” This approach aims to shrink laboratories onto a single chip by creating microscopic fluid channels with integrated micropneumatic control systems.

Today, there is a second fluidic revival, this time in the domain of soft robotics. Scaling microfluidic designs up to the millimeter-scale range (millifluidics) enables the higher flow rates necessary to drive robotic actuators. These robots exploit the nonlinear behaviors of soft materials to create lifelike motion and safer interactions, often utilizing pressurized air.

By building systems that “think” with the same air that powers them, we can drastically reduce the need for bulky electronic-to-pneumatic interfaces. This is the focus of my Soiboi Studio robotics lab. With millifluidic logic, I have steadily scaled the complexity of my designs. What began with a simple oscillator has most recently evolved into a clock featuring a soft, four-digit, seven-segment display.

What Is Millifluidics?

Building on microfluidics research from the early 2000s and recent developments from the Grover Lab at the University of California, Riverside, I’ve developed millifluidic devices using standard 3D printing and silicone casting. The basic architecture is simple: A flexible membrane is sandwiched between rigid layers embedded with networks of air channels.

Advertisement

Just as electronics rely on differing voltage potentials, these fluidic circuits operate on the pressure difference between atmospheric pressure (logical 0) and a near-vacuum at around −60 kilopascals of relative pressure (logical 1). Using negative pressure means the membrane is pulled into openings. This creates robust seals that allow me to replicate electronic building blocks.

Major components of the soft clock. A cast silicone membrane forms the face of the clock [top], while behind it sits 3D-printed millifluidic blocks [middle rows]. An Arduino Uno controls driver boards that operate solenoids, which are connected to valves that are attached to a vacuum pump [bottom row].James Provost

While fluidic resistors are easily realized by adjusting the channel geometry, the heart of the system is a valve that mimics a metal-oxide-semiconductor field-effect transistor, or MOSFET. This vacuum “transistor” features a flow layer with two chambers (the source and drain) divided by a central valve seat and a control layer containing a cavity (the gate). A membrane runs between the control and flow layers and normally prevents airflow between the source and drain chambers. To switch the transistor on, a vacuum is applied to the gate chamber, sucking the membrane into the cavity and lifting it off the seat. This opens a path for airflow, equivalent to closing an electric circuit. By adding a small aperture to the membrane, I created a check valve—the fluidic equivalent of a diode. By combining transistors and resistive “pull-down” channels, I can build a full suite of logic gates.

The original microfluidic designs that inspired me were fabricated from etched glass and milled acrylic. Adapting them for a standard 3D printer required reengineering the logic elements and mastering two critical fabrication techniques.

First, I need airtight prints, yet printed plastic is notoriously porous. By printing at elevated temperatures, slow speeds, and slight overextrusion, I was able to fill microscopic gaps. When you’re using transparent filament, there’s a handy visual indicator: The more transparent the plastic appears, the lower its porosity.

Advertisement

Second, I used glass for my print bed. By printing the upper and lower chambers directly against this bed, I got the interface surface to become mirror smooth. This finish is essential for creating reliable, airtight seals. A 0.3-millimeter silicone membrane is placed between the layers and secured with screws.

How Does the Soft Clock Work?

The clockface is a cast silicone membrane. Each digit segment is formed by a small underlying cavity. When air is evacuated from this cavity, the membrane is sucked inward to create a concave hollow; when atmospheric pressure is restored, the silicone pops back flush with the surface. The result is a mesmerizing, organic motion.

The “brain” of the clock is an Arduino Uno, while the fluidics significantly reduce the hardware footprint. A four-digit, seven-segment display with two separator dots would require 29 solenoid valves to control directly. My clock needs just 11 valves.

An illustration of the three chambers of a pneumatic transistor, with two lower chambers separated by a wall overlaid by a membrane, with an upper chamber straddling the wall. A pneumatic transistor is off when its upper control chamber is at atmospheric pressure [top]. When air is removed from the control chamber, it lifts a membrane, which allows air to flow between lower flow chambers and turns the transistor on [bottom]. James Provost

To understand how it works, consider a standard electronic four-digit, seven-segment LED display. This also uses 11 pins to drive its digits. (In clockface displays, an additional pin is required to drive the separator dots.) Every digit is connected to a shared data bus with seven lines, one per segment. The four control lines select individual digits. Only one digit is illuminated at time, and strobing the digits at least 50 times per second creates the illusion that all four are simultaneously illuminated.

Advertisement

Such high-speed switching is not possible with air. Instead, I rely on memory. Each segment acts like a capacitor: By evacuating its cavity (logic 1), you “charge” the segment; by restoring atmospheric pressure (logic 0), you discharge it. Hence, each digit acts as an independent 7-bit memory. If the system is sufficiently airtight, the segments maintain their state for several seconds.

Like the electronic display, the system utilizes a seven-line data bus. Each line connects to a solenoid valve that provides either vacuum or atmospheric pressure. To selectively address the individual digits, I placed a fluidic transistor between each segment and its data line. All the transistors’ control inputs for a given digit are combined into one “write enable” line connected to its own solenoid valve. Activating this valve allows me to write data into the corresponding digit’s memory.

The clock updates one digit per second, meaning a full cycle across the face takes 4 seconds. This cycle also drives the separator dots: A set of fluidic diodes connects the enable lines to the dots’ cavities. Consequently, as each digit is addressed, the dots pulse automatically.

This display is more than a clock; it is a soft robot that happens to tell time. By offloading computation to the same air that powers movement, the clock approaches a new class of machines that are simpler, lighter, and more integrated. I’m now developing a guide for getting started with vacuum-powered logic and may release a refined version of this clock in the future. Watching the silicone skin morph serves as a fascinating reminder that not all logic needs silicon; sometimes, all you need is flexible silicone and a flow of air.

Everything To Know Before Putting Your Car Key On An Android Phone

Published

on

Google’s approach to digital car keys is designed to be secure and shareable.

Smartphones are a common replacement for credit and debit cards thanks to features like Google Pay and Apple Pay. As more car makers update their tech, your smartphone might just be a replacement for your keys, too. Android’s support for digital car keys means that if your phone and car are compatible, you can use Google Wallet to unlock your vehicle, and, in some cases, even start it remotely. Knowing how the feature works and which smartphones support it will not only make the feature easier to set up, but it could keep you and your car safer in the long run.

What is Android’s digital car key feature?

Google added support for digital car keys with the release of Android 12 in 2021, one year after Apple brought its version of the same idea, CarKey, to iOS. Both let you store a digital copy of your car key in your default wallet app (Google Wallet, for Android devices) and control your car over a secure wireless connection. What extra functions are available to you depends on each vehicle’s maker, but the ability to unlock your car comes at a minimum. Because this smartphone key is entirely digital, and basically a representation of data associated with your car, it can also be shared with other phones via a simple text message. That’s even including iOS devices.

While digital car keys are a relatively recent addition in the grand scheme of smartphone features, the concept was in the works for several years before even Apple and Google hopped on board. The Car Connectivity Consortium, an industry group representing car and electronics companies, introduced its first “Digital Key” standard all the way back in 2018. The version of digital car keys available on smartphones today is built on an updated version of that same standard.

How do digital car keys work on Android?

On Android, once you’ve added your key to Google Wallet, your smartphone connects to your vehicle over Bluetooth and Ultra-wideband (UWB). The latter is the radio technology used in by things like Google’s Find Hub and Apple’s AirTags. Digital car keys can also fall back on an NFC (or Near Field Communication) connection if your Android device doesn’t have one of those other radios. Your car may also use NFC to authenticate your phone when you first add your key to Google Wallet.

These methods may actually be more secure than your car’s wireless fob. According to Google, “digital car keys offer enhanced security compared to key fobs, which are vulnerable to relay attacks.” Relay attacks amplify the signal from a key fob so that a car can be unlocked without you or the key needing to be nearby. 

Since one of the main features of UWB is the ability to determine something’s precise position relative to its radio, your digital car key won’t unlock anything unless your phone is physically near your car. Because the information associated with your car is stored securely on your phone, it also benefits from the same security methods that protect everything else you keep on your device, like photos or messages.

How do you add a digital car key to your Android phone?

How you actually go about adding your car key to Google Wallet will vary depending on your car. Some companies let you add the key directly through their app, while others send you an email with an “Add to Android” button. Some even let you set up the key through your in-car display. Whichever method your vehicle requires, you’ll need an up-to-date Android phone with the Google Wallet app installed and a Google Account to get started.

All three methods require logging in with your Google Account, agreeing to the terms of service and authenticating your smartphone, either over NFC through your car’s NFC reader (often housed in a built-in wireless charger), via an authentication code or both.

Which phones and cars support digital car keys?

Android’s digital car key feature requires you to have a smartphone running Android 12 or later to work. For example, that means you could use digital car keys on a Pixel 6 or later, a smartphone from Samsung’s Galaxy S26 series, a Motorola Razr or Razr Plus or a OnePlus 15. Google maintains a full list of compatible devices on its website, but any smartphone running the latest version of Android and that supports Bluetooth, UWB and NFC should fit the bill. To be clear, though, only Bluetooth and NFC are mandatory for the basic functions of digital car key to work. UWB enables additional features.

In terms of cars, support for digital car keys is mostly limited to premium and luxury brands and newer electric vehicles, but that could change over time. Kia’s EV3, EV4, EV5, EV6 Facelift and EV9 all support digital car keys. So does the Hyundai IONIQ 5 and IONIQ 5N. If you drive a Volvo EX90, a BMW X5 or a Rivian released after 2025, you’re also in luck.

If your car isn’t in that short list, your car brand might still support digital car keys on Android. Here are the main US and European brands that support the feature, according to Google’s website:

  • Audi

  • BMW

  • Genesis

  • Hyundai

  • Kia

  • LEXUS

  • Mercedes-Benz

  • MINI

  • Polestar

  • Porsche

  • RAM

  • Toyota

  • Volvo

Are there any risks to using digital car keys?

While UWB and NFC might make a digital car key on your phone more secure in some ways than a simple fob, that doesn’t mean using your smartphone as a key is free from risk. In fact, adding your car keys to your phone makes losing it even riskier. If you don’t have adequate security measures set up (like using a weak passcode, for example) it’s that much easier for someone to access your car if they steal your phone. Relying on your smartphone over physical keys might also cause problems if a software issue prevents you from using Google Wallet or, God forbid, you lose your phone.

The simple solution is to always carry your key as a backup in the same way you carry your wallet if you use Google Pay. You can always fall back on a physical key or card when your phone fails you. You might also consider enabling biometric authentication and disabling passive entry — Google’s method for automatically unlocking cars — to make sure you have to be intentionally unlocking your car to get inside it. If your phone is stolen, you can also delete or suspend your digital key from another device so it can’t be used until you get your phone back.

Fonoa raises $110M and buys PwC’s tax software to build a real-time compliance platform

Published

on

The Dublin-registered tax-tech firm paired a Series C led by Headline with the acquisition of PwC’s Indirect Tax Edge, a bet that periodic compliance is giving way to real-time.


Indirect tax is the kind of problem most people never think about until a government decides to watch every transaction in real time.

That is now happening across much of the world, and Fonoa has just raised $110 million and bought a piece of PwC on the strength of it.The company announced both moves together, framing them as one bet rather than two.

The funding is a Series C led by the venture firm Headline, with new investors Eurazeo and Forestay Capital joining existing backers including Index Ventures, OMERS, Coatue and Dawn Capital. Fonoa, registered in Dublin and run by co-founder and chief executive Davor Tremac, did not disclose a valuation.

The capital, the company said, will go toward building more autonomous, AI-driven intelligence into its compliance platform.

The acquisition is the more unusual half. Fonoa is taking over PwC’s Indirect Tax Edge, an enterprise compliance product used by some of the world’s largest organisations to handle VAT and GST filing, e-filing and transactional tax data.

The deal builds on an arrangement first announced in 2024, when Fonoa agreed to acquire the product from PwC; the latest step folds Edge into Fonoa’s platform while PwC continues to support its clients with consulting and reporting around it.

The logic Tremac set out is structural. Most enterprise tax functions, he argued, run on a patchwork of point solutions, a tool for one country, a system for one step, a spreadsheet for the gaps between, which worked when tax was slower and largely national.

It stops working once authorities demand real-time e-invoicing and transaction-level reporting across borders, which is increasingly the norm in markets representing the bulk of global trade.

Edge customers, in this framing, are running best-in-class periodic compliance but lack a connected path to real-time reporting from inside the same trusted system. Fonoa’s pitch is that it can give them that continuity, full lifecycle coverage on a single data model, without making them start over, and layer AI-driven monitoring on top of workflows that used to demand heavy manual effort.

That a Big Four firm chose to hand a live enterprise product to a scale-up, rather than build the real-time layer itself, is the part of the announcement that carries the most weight.

It is a vote of confidence in Fonoa’s infrastructure, and it slots into a broader European pattern of B2B fintech and regulatory-technology consolidating as compliance grows more demanding, the same shift that has lifted firms like the Dutch SME bank Finom.

The raise and the acquisition are, on Fonoa’s account, two expressions of the same wager: that indirect tax is bifurcating between firms that move to connected, real-time-ready systems and those left managing the gaps as regulators close in.

The unanswered questions are the usual ones for a company-issued announcement, the valuation, the price paid for Edge, the eventual headcount, none of which Fonoa disclosed. What it did disclose is direction, and a Big Four partner willing to stand behind it.
