The fine researchers at Google have released the juicy details on EntrySign, the AMD Zen microcode issue we first covered about a month ago. And to give away the punchline: cryptography is hard. It’s hard in lots of ways, but the AMD problem here is all about keeping track of the guarantees provided by cryptographic primitives.

If you’re coming to Hackaday Europe 2025, you’ve got just over a week to get your bags packed and head on out to Berlin. Of course you have tickets already, right? And if you were still on the fence, let us tempt you with our keynote talk and some news about the Friday night meetup, sponsored by Crowd Supply.
This week, Jonathan Bennett and Aaron Newcomb talk with Joao Correia about TuxCare! What’s live patching, and why is it so hard? And how is this related to .NET 6? Watch to find out!

When it comes to the majority of sports broadcasting, it’s all about the visual. The commentators call the plays, of course, but everything you’re being shown at home is on a screen. Similarly, if you’re in the stadium, it’s all about getting the best possible view from the best seats in the house.
Ultimately, the action can be a little harder to follow for the vision impaired. However, one company is working hard to make sports more accessible to everyone. Enter OneCourt, and their haptic sports display technology.

The result is a nice adapter that allows them to be used with Kailh chocs — you can find the file on Thingiverse, and check out the video after the break to see how they sound on a set of clicky white chocs.
Those white chocs are attached to a ThumbsUp! v8 keyboard, a line that [Sasha K.] designed. His daily driver boards are on v9 and v10, but the caps were getting jammed up because of the spacing on those. So instead, he used v8 which has Cherry MX spacing but also supports chocs.
As you can see, there is not much to the adapter, which essentially plugs the Selectric keycap’s slot and splits the force into the electrical outlet-style pair of holes that chocs bear This feels like an easier problem to solve than making an adapter for MX-style switches. What do you think?

Join us on Wednesday, March 5 at noon Pacific for the Deep Space DX Hack Chat with David Prutchi!
In the past 70-odd years, the world’s space-faring nations have flung a considerable amount of hardware out into the Void. Most of it has fallen back into Earth’s gravity well, and a lot of what remains is long past its best-by date, systems silenced by time and the harsh conditions that rendered these jewels of engineering into little more than space flotsam.
Luckily, though, there are still a few spacecraft plying the lonely spaces between the planets and even beyond that still have active radios, and while their signals may be faint, we can still hear them. True, many of them are reachable only using immense dish antennas.
Not every deep-space probe needs the resources of a nation-state to be snooped on, though. David Prutchi has been listening to them for years using a relatively modest backyard antenna farm and a lot of hard-won experience. He’s been able to bag some serious DX, everything from rovers on Mars to probes orbiting Jupiter. If you’ve ever wanted to give deep space DX a try, here’s your chance to get off on the right foot.
Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, March 5 at 12:00 PM Pacific time. If time zones have you tied up, we have a handy time zone converter.
It’s been quite a week for asteroid 2024 YR4, which looked like it was going to live up to its “city killer” moniker only to be demoted to a fraction of a percent risk of hitting us when it swings by our neighborhood in 2032. After being discovered at the end of 2024, the 55-meter space rock first popped up on the (figurative) radar a few weeks back as a potential risk to our home planet, with estimates of a direct strike steadily increasing as more data was gathered by professional and amateur astronomers alike. The James Webb Space Telescope even got in on the action, with four precious hours of “director’s discretionary” observation time dedicated to characterizing the size and shape of the asteroid before it gets too far from Earth. The result of all this stargazing is that 2024 YR4 is now at a Level 1 on the Torino Scale of NEO collision risk, with a likely downgrade to 0 by the time the asteroid next swings through again in 2028. So, if like us you were into the whole “Fiery Space Rock 2032” thing, you’ll just have to find something else to look forward to.
