There’s not one, but two side-channel attacks to talk about this week. Up first is Pacman, a bypass for ARM’s Pointer Authentication Code. PAC is a protection built into certain ARM Processors, where a cryptographic hash value must be set correctly when pointers are updated. If the hash is not set correctly, the program simply…

We’re not in the habit of recommending Kickstarter projects here at Hackaday, but when prototype hardware shows up on our desk, we just can’t help but play with it and write it up for the readers. And that is exactly where we find ourselves with the Turing Pi 2. You may be familiar with the…
Ding, dong; the office is dead. The real office is in your head. This is what I tell myself when working from home gets too weird, too stale, too impossible. By now, many of you know some version what I’m talking about. Our circumstances may vary wildly, but the outcome is the same: working from…

With a seemingly endless list of shortages of basic items trotted across newsfeeds on a daily basis, you’d be pardoned for not noticing any one shortage in particular. But in among the shortages of everything from eggs to fertilizers to sriracha sauce has been a growing realization that we may actually be running out of…
When it comes to high-performance desktop PCs, particularly in the world of gaming, water cooling is popular and effective. However, in the world of datacenters, servers rely on traditional air cooling more often than not, in combination with huge AC systems that keep server rooms at the appropriate temperature. However, datacenters can use water cooling,…

The tech news channels were recently abuzz with stories about strange signals coming back from Voyager 1. While the usual suspects jumped to the usual conclusions – aliens !! – in the absence of a firm explanation for the anomaly, some of us looked at this event as an opportunity to marvel at the fact…

Generally when we consider the many plants around us, we imagine them efficiently using the electromagnetic radiation from the Sun via photosynthesis in their leaves – pulling carbon-dioxide from the air, as well as water from the soil via their roots, and grow as quickly. as they reasonably can. In reality, the efficiency of this…

Recently, I stumbled upon a cool write-up by [DHowett], about reprogramming a Framework laptop’s Embedded Controller (EC). He shows us how to reuse the Caps Lock LED, instead making it indicate the F1-F12 key layer state – also known as “Fn lock”, AKA, “Does your F1 key currently work as F1, or does it regulate…
There are many wonderful places we’d like to visit in the universe, and probably untold numbers more that we haven’t even seen or heard of yet. Unfortunately they’re all so far away. A best-case-scenario trip to Mars takes around six months with present technology, meanwhile, if you want to visit Alpha Centauri it’s a whole…

Here’s a scenario. You have a microcontroller that reads a number of items – temperatures, pressures, whatever – and you want to have a display for your Linux desktop that sits on the panel and shows you the status. If you click on it, you get expanded status and can even issue some commands. Most…
