x264 is kinda absurdly good at compressing screencasts, even a nearly lossless 1440p screencast will only have about 1 Mbit/s on average. The only artifacts I can see are due to 4:…

> I used a Satechi USB-C power tester and measured an 8% peak power savings using UASP. That means you'd get 8% more runtime on a battery if you do a lot of file transfers. No no, …

The late 1990s called and want their Numalink back.

> DAB solves that minor issue at least. Enter Germany, where it was decided DAB is not a federal matter and basically you have 16 small states with entirely different stations avai…

CRTs are "dumb" devices, they literally just amplify the R/G/B analog signal while deflecting a beam using electromagnets according to some timing signals. As far as input lag goes…

> Animations and intentional delays. It can't be said, how much faster a machine feels when something like MenuShowDelay is decreased to 0, or the piles of animations are sped up. …

I disagree. What you describe is a problem of interaction design founded on bad assumptions; with good interaction design I don't have to show the user that the computer is doing s…

From a modern point of view it's not a challenge. Historically voice encryption was politically only meant for state use, with strict controls, and us plebs not getting any voice e…

Very clever to use the same pinout as the PCIe "flexible risers" that already use USB cables, so only the chip replacement is necessary.

> Meanwhile, pointing at memory latency as the flaw in Ryzen has been a popular misdirection for a while now. How is it a misdirection? The data is accurate and memory latency scal…

IIRC L3 is slightly slower on Zen 2, main memory as mentioned much slower. Clock speed advantage -- Most Zen 2 CPUs don't overclock to 4.5 GHz on any core, let alone all-core. The …

As a desktop user, my CPU tends to be mostly idle. So overall power efficiency is impacted a lot by idle power consumption; my AMD Ryzen CPU alone draws significantly more power in…

For what it's worth, Intel is still faster in most applications, simply by virtue of having a clock speed advantage that by far exceeds any IPC difference, and also by having much …

Which compiler that can compile modern C++ doesn't always inline a static single-caller function?

Correct, a CMOS sensor with a rolling shutter looks and handles a lot like a piece of DRAM. Pixels are arranged in rows and colums; capturing a frame works just like a sequential r…

Autochrome is pretty much just subpixels. You capture and view a greyscale image through the same dots-of-color filter plate, and thus you see color, just like an image sensor uses…

Sometimes I use a quad-core laptop with 2 GB of memory and no swap (because it doesn't have enough disk space for a meaningful amount of swap) and five tabs is practically a hard l…

I guess you upgraded the RAM to 8 GB? Because I don't see how the web is usable on a machine with 2 GB of RAM...
