I also switched to an Ergodox EZ (about 2 years ago), and the switch was very painful. At first, my speed was divided by 2. Using some typing practice, I managed to get to my usual speed on a normal keyboard and then thought: good, now I ca

This "nothing to hide" discussions always remind me of this great essay "We should all have something to hide": https://moxie.org/blog/we-should-all-have-something-to-hide/

Even if the rich were paying more taxes, that does not automatically mean that they are bearing the tax burden, because of "tax incidence" [0]. A rich person has usually much more bargaining power and can more easily shift the bur

It was FM radio, and I think the studio sends its data to the antenna using some internet link, which was down.

Agreed about privacy, but the "Mobile phones continue to work during a disaster" is a very optimistic view. It was no a disaster, far from it. In Belgium, few years ago, a fire under a bridge broke an bunch of fibers from the main

It is not only what the data is currently used for (mainly ads), but what it could be used for in the future: once collected, any data will be kept forever. And that is much more frightening.

As a kid, I remember playing a racing game where you could just wait for the AI to cover one complete lap (on the three to go). Since you were so much behing, the AI would become very slow. After being overtaken, you could start racing and

Good question. Jumping around the memory is clearly not good for throughput. Before the change, the mixing of requests between processes was already detrimental for performance anyway. All I can say is that we needed a fixed bandwidth and

It was very simple, I kept all the "logical" addresses the same, but swapped some low address bits with high address bits at the memory controller interface. With this, the slowly moving indexes became big jumps. This avoids readi

When I read about rowhammer, I did analyse carefully the memory request pattern and found many similarities to a rowhammer attack on PC. It was several processes issuing small requests on alternating rows, with slowly moving indexes. After

FPGA developer here. In a former project (with a custom board and FPGA, no processor), we encountered random bugs. We put many checks and finally came to the conclusion that our DDR modules were flipping bits randomly, but only on normal lo

Maybe, but I struggle to find a way to express preferences without information about price. And it will add a few hundred million more variables into the optimization problem.

I have an Ergodox EZ, with many customizations, and I love it too. I wanted to use dual function keys, but as soon as there is one such key on the keyboard, I feel a delay for all the key presses. It is ok for the dual function key (the fir

Unrolling the computation of the series, it is possible to compute f(n) using only f(n-4) and f(n-8): f(n) = 7*f(n-4)-f(n-8) So, using 4-vector operations, you can compute 4 numbers in one step.
