Hackaday Links: October 25, 2026

Some disappointing, but perhaps not entirely unsurprising news this week out of Denmark — after announcing last year that they would transition away from Microsoft’s proprietary software, the realities of making it work seem to have caught the government off guard. The word is that a trial program immediately ran into problems when government employees that had been given Collabora tried to collaborate with their peers running Office, and has since been quietly abandoned.

Although there’s probably a joke to be made about different parts of the government not knowing what the other ones are talking about, the reality is that if one group of staffers can’t reliably access the data being produced by another, that’s a pretty big problem. Of course, had they simply asked us nerds, we could have advised them that these sort of issues are inevitable if you don’t fully commit to the effort.

Had the entire government moved to the Open Document Format (ODF) at once they would have avoided the issue, at least when it came to newly created documents, but obviously that’s a considerably larger undertaking than installing Collabora or OpenOffice on a few dozen machines and calling it a day. There’s no word yet on how this stumble will impact Denmark’s larger effort to free themselves of proprietary software, but we’d hazard a guess it’s not a great sign. Hopefully things go better for the Dutch.

Japan Launches Mission To Study Martian Moon

Humanity has been sending robotic explorers to Mars since the 1970s, and for our efforts we’ve been rewarded with not only incredible imagery of the Red Planet’s magnificent desolation, but a wealth of information about the alien world and how it’s changed over the last several billion years. But comparatively, we know almost nothing about the planet’s two moons, Phobos and Deimos. In fact, as recently as the 1960s, there were some scientists that believed the unusual shape, mass, and orbit of Phobos hinted at the possibility that it was no moon at all, and was in actuality a derelict spacecraft of some type.

Martian Moons eXploration Spacecraft

Once the first Viking probes arrived at Mars, we had the photographic evidence and up-close measurements to prove that Phobos wasn’t artificial. But even today, we still don’t know exactly what it is. The data suggests that it’s not solid rock, and that large voids may be hiding under its surface. While we can be fairly sure there won’t be any mummified remains of Martian astronauts to be found within Phobos, vast deposits of ice are a tantalizing possibility.

With the launch of the Martian Moons eXploration (MMX) mission earlier this week, the Japan Aerospace Exploration Agency (JAXA) hopes to bring us one step closer to understanding the formation and structure of Phobos. Should everything go to plan, MMX will deploy a small rover to its tenuous surface in 2029, and by 2031, a sample return capsule will bring pieces of the mysterious moon back to Earth for further study.

The Age Of Altair

I recently got the Amazon Christmas toy book in the mail, and it is definitely the modern version of the Sears Christmas Wish Book for last century’s youth. Or at least the majority of last century’s youth. For the true hacker, we had a different set of wishes. Recently, I found something I’ve clung to for over 50 years: the 1975 “The Age of Altair” catalog from MITS. Now that was a wish book!

The poor thing has been dragged around for decades and, I’m sad to say, it looks it. It isn’t totally trash, but I decided I should scan it. Then I realized that Bitsavers has already done it for me and with a much nicer copy, too. The images in this post are from their scan instead.

About the Altair

The magazine that started it all (World Radio History).

If your first computer ran Windows, you might not get the significance of the Altair. Back in 1974, the idea of having your own computer was practically ludicrous. Sure, Radio Electronics had published plans for the Mark 8 in July of that year. But it used an anemic 8008 CPU, and it wasn’t easy to get all the parts you’d need to build one. Other limited computers, like the Kenbak-1 or the occasional surplus minicomputer, ended up in personal hands. But you couldn’t just decide you wanted a real computer, plunk down some money, and have one delivered unless you had extremely deep pockets.

To stay on magazine stands longer, old print mags would come out earlier than their cover date suggested. The January 1975 Popular Electronics arrived, actually, in December of 1974 — just in time for the holidays. It showed a computer you could buy as a kit or assembled: the Altair 8800. Many of us were mesmerized by the idea of owning an actual useful computer.

Hackaday Links: October 17, 2026

While Hackaday doesn’t maintain a crime blotter, we couldn’t help but start this week’s post off with a bit of civil disobedience — a retired professor from the University of Pennsylvania was arrested earlier this week for standing in front of a delivery robot.

Granted, she was standing there for long enough that the police were eventually called, but still. Previous reporting indicates that Carolyn Marvin has a history of blocking delivery robots as a form of protest, but this is the first time law enforcement got involved. We’re not lawyers here at Hackaday, so we can’t say for sure whether or not blocking the progress of a robot engaged in commercial operation actually violates any laws. But we do know that refusing a lawful request from a police officer will get you in trouble, and that seems to be what Marvin was actually charged with when she refused to move.

Discovering SDRs Everywhere

To quote commenter [douyarou], “It’s like our little version of a Precambrian explosion”. A bunch of hackers have discovered, independently and building on each other’s work, software-defined radio (SDR) capabilities in more places than you can shake a stick at.

It all started with [Espargos] and [h0m3us3r] apparently independently discovering that the ESP32 family of chips had a “secret” debug mode that allowed direct access to the radio that’s normally used for WiFi. While the 2.4 GHz radio signal is almost always immediately converted into data by the MAC hardware, here they found a way to listen in upstream, to the raw IQ data.

Seeing this, folks were immediately inspired to find out if they could transmit as well. [marble] not only got transmit functionality working, but integrated the part in with the standard osmosdr data flow, which meant that a whole bunch of existing tools were ready to go. We didn’t know about it at the time, but apparently [jochenhammes] and [z1000biker] concurrently had their TX-capable hacks up and running: here and here.

At this point, folks have already started to use the capabilities for broadcasting digital TV signals, voice signals, FM Hell, and other hijinks. This reminds us of the early days of the RTL-SDR project, when a competent, if receive-only, SDR functionality was found in a bunch of USB TV-tuner dongles. Once the hardware capabilities were sussed out, people started writing all sorts of useful software, and it gave rise to all manner of radio projects, from simply poking at domestic wireless devices to tracking all the airplanes in the world as they fly by.

[Tom] and I were discussing this on the podcast, and he remarked that of course there are SDRs hidden everywhere there is a radio unit these days, and the question is just whether or not we could hack them into usability. And before the podcast was even finally edited, [Samson1te] told us about his find in the LR2021 LoRa chip. This is a radio that’s designed to be a radio, with 16-bit resolution, and covering lower frequencies from 150 MHz to 960 MHz.

Compared to the RTL-SDR revolution, this is all happening at incredible speed. Each of these hacks will enable us to use different slices of radio spectrum with different degrees of ease, but it’s clear that the cost of entry into playing around with digital radio has just dropped precipitously. We will see hundreds of new signals hacks in the next few months – the floodgates have been opened.

Hackaday Podcast Episode 391: Tuned In To ESP32 SDR, New Old Pagers, And Bugs On Mars

Hackaday Editors Elliot Williams and Tom Nardi start this episode off with a discussion about Philadelphia’s budding hacker conference and the imminent retirement of the EZ80. After considering the parallels between the wide world of aviation headsets and our personal projects, talk moves on to the exciting developments in the world of software-defined radio on the ESP32, a Meshtastic pager from a bygone era, and how all the wild flying machines entered into DARPA’s Lift Challenge ended up losing to a simple helicopter.

You’ll also hear about turning plastic bottles into printer filament, pushing e-ink screens to their limits, and browsing the web on the PSP in 2026. To wrap things up they’ll marvel at all the modern abstraction sitting between software and the memory it’s running on, and revisit some RF concepts that might be particularly useful now that everyone is playing with a new SDR device.

This Week In Security: Critical DNS Keys Rotated, Hacking Freezers Isn’t Cool, OpenAI Spies On Itself, And Advanced Hardware Wallet Hacks

Critical Internet keys changed this week. Did you notice?  The keys behind DNSSEC, the system for cryptographically validating DNS responses, rolled over on October 11 2026. This is the second time the DNSSEC keys have rotated since the system was implemented, and the first time in 2018 didn’t exactly go entirely smoothly.

DNS is what resolves a host name and turns it into an IP address. It underpins web browsing, email, and just about every other connection. It’s also a very early Internet protocol, written in both a simpler, less paranoid era, and an era where encryption was computationally expensive and legally problematic. DNS offers little protection against malicious actors spoofing responses, and the impacts range from phishing to redirecting email to just about any other manipulation of connections you can image.

DNSSEC addresses this by creating a chain of trust between DNS resolvers — the servers that forward the DNS query into the DNS infrastructure and return the results — and the global DNS servers. Part of this chain of trust is the root key that each resolver must have and trust, and this key is what changed this week.  DNSSEC resolvers automatically watch for a new root of trust key, but the key must be signed by the previous root of trust, and is checked for at least 30 days before it is trusted.  If someone were able to issue a bogus certificate, they would have to maintain control of the infrastructure for over a month before DNS resolvers would trust it.

The process of distributing the new key actually began more than a year ago, on January 11, 2025, to give DNSSEC resolvers time to get the new key. DNSSEC services should have had plenty of time to obtain and trust the new key, and unless DNS stopped working for you this week, they did their job.

The next major change for DNSSEC will require more profound changes to deploy a new signing algorithm that will be post-quantum secure.
