Hackaday Links: March 8, 2026

As pointed out by Tom’s Hardware, it’s been 26 years since the introduction of the gigahertz desktop CPU. AMD beat Intel to the punch by dropping the 1 GHz Athlon chip on March 6th of 2000, and partnered with Compaq and Gateway (remember them?) to deliver pre-built machines featuring the speedy silicon just a week later. The archived press release announcing the availability of the chip makes for some interesting reading: AMD compares the accomplishment with Chuck Yeager breaking the sound barrier, and mentions a retail price of $1,299 for the CPU when purchased in 1,000 unit quantities. In response Intel “launched” their 1 GHz Pentium III chip two days later for $990, but supply problems kept it out of customer’s hands for most of the year.

Speaking of breaking a barrier, Mobile World Congress took place this week in Barcelona, where TechCrunch reports there was considerable interest in developing a sub-$50 smartphone. The GSM Association’s Handset Affordability Coalition is working with major telecom carriers in Africa and as of yet unnamed hardware partners to develop the low-cost 4G device with the hopes of bringing an additional 20 million people online. While the goal is worthy enough, industry insiders have pointed out that the skyrocketing cost of memory will make it particularly challenging to meet the group’s aspirational price point.

New Artemis Plan Returns To Apollo Playbook

March 4, 2026 by Tom Nardi 54 Comments

In their recent announcement, NASA has made official what pretty much anyone following the Artemis lunar program could have told you years ago — humans won’t be landing on the Moon in 2028.

It was always an ambitious timeline, especially given the scope of the mission. It wouldn’t be enough to revisit the Moon in a spidery lander that could only hold two crew members and a few hundred kilograms of gear like in the 60s. This time, NASA wants to return to the lunar surface with hardware capable of setting up a sustained human presence. That means a new breed of lander that dwarfs anything the agency, or humanity for that matter, has ever tried to place on another celestial body.

Unsurprisingly, developing such vehicles and making sure they’re safe for crewed missions takes time and requires extensive testing. The simple fact is that the landers, being built by SpaceX and Blue Origin, won’t be ready in time to support the original Artemis III landing in 2028. Additionally, development of the new lunar extravehicular activity (EVA) suits by Axiom Space has fallen behind schedule. So even if one of the landers would have been ready to fly in 2028, the crew wouldn’t have the suits they need to actually leave the vehicle and work on the surface.

But while the Artemis spacecraft and EVA suits might be state of the art, NASA’s revised timeline for the program is taking a clear step back in time, hewing closer to the phased approach used during Apollo. This not only provides their various commercial partners with more time to work on their respective contributions, but critically, provides an opportunity to test them in space before committing to a crewed landing.

We’ll start this week off with a bit of controversy from Linux Land. Anyone who’s ever used the sudo command knows that you don’t see any kind of visual feedback while entering your password. This was intended as a security feature, as it was believed that an on-screen indicator of how many characters had been entered would allow somebody snooping over your shoulder to figure out the length of your password. But in Ubuntu 26.04, that’s no longer the case. The traditional sudo binary has been replaced with a one written in Rust, which Canonical has recently patched to follow the modern convention of showing asterisks on the password prompt.

As you might expect, this prompted an immediate reaction from Linux greybeards. A bug report was filed just a few days ago demanding that the change be reverted, arguing that breaking a decades-old expectation with no warning could be confusing for users. The official response from a Canonical dev was that they see it the other way around, and that the change was made to improve the user experience. It was also pointed out that those who want to revert to the old style of prompt can do so with a config change. The issue was immediately marked as “Won’t Fix”, but the discussion is ongoing.

Speaking of unexpected changes, multiple reports are coming in that the February security update for Samsung Galaxy devices, which is currently rolling out, removes several functions from the Android recovery menu. After the update is applied to phones such as the S25 and Fold 7, long-standing features, such as the ability to wipe the device’s cache partition or install updates via Android Debug Bridge (ADB), disappear.

Hackaday Links: February 22, 2026

We’ll start things off this week with some breaking news from NASA: just days after the space agency announced the Artemis II crew was preparing to blast off towards the Moon as soon as March 6th, a new problem with the Space Launch System rocket has pushed the launch back indefinitely. According to NASA Administrator Jared Isaacman, problems encountered while loading helium into the Interim Cryogenic Propulsion Stage (ICPS) necessitate rolling the massive rocket back to the Vehicle Assembly Building (VAB) for diagnosis and repair.

The logistics of shuffling the vehicle 6.8 kilometers (4.2 miles) from the pad to the VAB is going to eat up at least a week, and sending it back the other way is naturally just as much of a production. Add in the time they’ll need to actually figure out what’s wrong with the ICPS and make the necessary repairs, and it’s easy to see why a March launch is almost certainly off the table. It’s frustrating to see the Artemis II mission get delayed this close to launch, but sending humans into space isn’t the sort of thing you can cut corners on.

Ask Hackaday: Do You Have A Dead Man’s Switch?

February 20, 2026 by Tom Nardi 72 Comments

During the Cold War, the specter of a nuclear “dead man’s switch” was central to the concept of Mutually Assured Destruction (MAD). In the event that one side was annihilated by the other, an automated system would be triggered to deliver a revenge strike that would ultimately destroy the attacker. It was the ultimate defense, as your enemy will never attack if they know doing so will inevitably lead to their own destruction.

The same idea has occasionally been employed by whistleblowers and journalists as well. Should the individual fail to check in regularly, a series of predetermined events will be set into motion. Again, the idea is defensive in nature. If somebody is in possession of information so damning that they could be abducted or even killed to keep it quiet, making arrangements to have that information be released to the public in the event anything should happen to them is a great way to stay safe.

A nuclear dead man’s switch is a key plot point in *Dr. Strangelove*.

But what about for the average person? In the past, there was no need for most people to think about something as elaborate as a dead man’s switch. But we live in interesting times, to say the least. In an information society such as ours, whistleblowers have never been more common, and the Internet has significantly blurred the definition of what it means to be a journalist.

For those living under a repressive regime or in a war zone, simply posting to social media can provide the outside world with an unfiltered look at what’s actually happening on the ground. A teenager with a cell phone has the potential to reach a wider audience than the legacy media — a powerful, but dangerous, proposition.

Even if you’re not in the middle of political upheaval, there are still reasons you might want to have previously secret information made available in the event of your death or incapacitation. Perhaps you’d like to send your loved ones a final personal message, or make sure the passwords for all your accounts get in the hands of whoever will be handling your estate.

Of course, one could argue that could be accomplished with little more than a notebook hidden in your sock drawer. But this is Hackaday, and over-engineering is the name of the game. So do you have a dead man’s switch? How is it implemented? Or is the whole idea just a bit too out there for you?

The Complicated Legacy Of Mind Controlled Toys

February 17, 2026 by Tom Nardi 15 Comments

Imagine a line of affordable toys controlled by the player’s brainwaves. By interpreting biosignals picked up by the dry electroencephalogram (EEG) electrodes in an included headset, the game could infer the wearer’s level of concentration, through which it would be possible to move physical objects or interact with virtual characters. You might naturally assume such devices would be on the cutting-edge of modern technology, perhaps even a spin-off from one of the startups currently investigating brain-computer interfaces (BCIs).

But the toys in question weren’t the talk of 2025’s Consumer Electronics Show, nor 2024, or even 2020. In actual fact, the earliest model is now nearly as old as the original iPhone. Such is the fascinating story of a line of high-tech toys based on the neural sensor technology developed by a company called Neurosky, the first of which was released all the way back in 2009.

Yet despite considerable interest leading up to their release — fueled at least in part by the fact that one of the models featured Star Wars branding and gave players the illusion of Force powers — the devices failed to make any lasting impact, and have today largely fallen into obscurity. The last toy based on Neurosky’s technology was released in 2015, and disappeared from the market only a few years later.

I had all but forgotten about them myself, until I recently came across a complete Mattel Mindflex at a thrift store for $8.99. It seemed a perfect opportunity to not only examine the nearly 20 year old toy, but to take a look at the origins of the product, and find out what ultimately became of Neurosky’s EEG technology. Was the concept simply ahead of its time? In an era when most people still had flip phones, perhaps consumers simply weren’t ready for this type of BCI. Or was the real problem that the technology simply didn’t work as advertised?

It probably won’t come as much of a surprise to find that most of the Hackaday staff aren’t exactly what you’d call sports fanatics, so we won’t judge if you didn’t tune in for the Super Bowl last week. But if you did, perhaps you noticed Ring’s Orwellian “Search Party” spot — the company was hoping to get customers excited about a new feature that allows them to upload a picture of their missing pet and have Ring cameras all over the neighborhood search for a visual match. Unfortunately for Ring, the response on social media wasn’t quite what they expected.

One commenter on YouTube summed it up nicely: “This is like the commercial they show at the beginning of a dystopian sci-fi film to quickly show people how bad things have gotten.” You don’t have to be some privacy expert to see how this sort of mass surveillance is a slippery slope. Many were left wondering just who or what the new system would be searching for when it wasn’t busy sniffing out lost pups.

The folks at Wyze were quick to capitalize on the misstep, releasing their own parody ad a few days later that showed various three-letter agencies leaving rave reviews for the new feature. By Thursday, Ring announced they would be canceling a planned expansion that would have given the divisive Flock Safety access to their network of cameras. We’re sure it was just a coincidence.

Speaking of three-letter agencies, the Environmental Protection Agency has announced this week that they will no longer incentivize the inclusion of stop-start systems on new automobiles. The feature, which shuts off the engine when the vehicle comes to a stop, was never actually required by federal law; rather, the EPA previously awarded credits to automakers that added the feature, which would help them meet overall emission standards. Manufacturers are free to continue offering stop-start systems on their cars if they wish, but without the EPA credits, there’s little benefit in doing so. Especially since, as Car and Driver notes, it seems like most manufacturers are happy to be rid of it. The feature has long been controversial with drivers as well, to the point that we’ve seen DIY methods to shut it off.
