OK, this is completely useless but definitely a fun project.

Indeed, CPU prefetchers are really good nowadays. Now you know what to do to keep your code fast.

A good reminder that "push it to the GPU and it'll be faster" isn't true. If you move a workload to the GPU you likely have to rethink quite a bit how it's done.

Definitely a cool hardware hack. There are really many form factors and hardware options to explore for better XR experience.

The hardware is there, the software not so much. Now I'd argue that the author overestimate the availability of said hardware in households.

Nice trick for highly performance sensitive data structures. Making data CPU local instead of thread local you can make a mechanism which is especially cache friendly.

Nice post explaining the need of ACPI or Device Tree and how they are leveraged by kernels.

It looks like analog chips for neural network workloads are on the verge of finally becoming reality. This would reduce consumption by an order of magnitude and hopefully more later on. Very early days for this new attempt, let's see if it holds its promises.

A good question, it is somewhat of a grey area at times. We need to come up with better answers.

It's interesting to see such a reverse engineering of this infamous bug straight from the gates layout.

This is an excellent milestone reached for the OpenWrt project. Easily available hardware is a must. It's rather cheap too.

We always think about the energy consumption, but large data centers gobble billion liters of water too. This would need to be improved.

Nice to see open hardware for VR hitting such a price point.

Fascinating research about side-channel attacks. Learned a lot about them and website fingerprinting here. Also interesting the explanations of how the use of machine learning models can actually get in the way of proper understanding of the side-channel really used by an attack which can prevent developing actually useful counter-measures.

Nice graphic tricks when the hardware was harder to work with. It's amazing how much we could fit back then out of sheer motivation.

A reminder that Secure Boot is worth nothing if the device makers don't manage cryptographic keys properly...

We keep finding floppies in use at surprising places. There's clearly lot of inertia for technologies getting replaced.

As Moore's law fades away this question is indeed essential. Looks like there will be more pressure on software and algorithms than before (at last one might say, we had decades of waste there). Streamlining hardware architectures will have a role too, we might see simpler cores in greater numbers.

Nice reverse engineering of a NFC chip used in a disposable transportation ticket.

Very nice explanation and metaphors on how CPUs cache levels work.
