In hardware engineering this is called critical path.

Amdahl's law is common sense, but also the one of the reasons premature optimization is the root of all evil. A small speedup on the longest (by time) part of the program is usuall…

It seems the limit does not apply to Quotes and Liked tab on users profiles.

The bottleneck is bandwidth and storage not computer power. Data from sensor and to display are usually (but not always) raw and uncompressed. To go beyond 8k 120fps we will need f…

Flow instability is one of the biggest challenges to get them to operate for long time without blowing up. Of course, there are others. Any progress on the control of chaotic flow …

Also detonation. It Could make Rotation Detonation Engines possible.

“[Balloons] have extremely small radar and thermal cross sections, making them relatively invulnerable to most traditional tracking and targeting method". https://www.thedrive.com/…

They have smaller cross section than many stealth jets: https://www.thedrive.com/the-war-zone/why-shooting-down-chin...

Alder Lake and Raptor Lake workstation (W680 Chipset) doesn't have AVX512 enabled.

Now we only need a consumer CPU from Intel with AVX-512 enabled.

I don't think Apple has interest in small markets. They are really good at making stuff at huge volumes.

Silicon on lunar regolith is mostly plagioclase, pyroxene, and olivine. Quartz (SiO2) is Not exactly comparable.

The aviation industry is averse to change. Most planes are still being updated with floppy disk. But I agree. High end commercial solid storage, such Optane, would likely exceeds t…

I wish the Sony protocol was open source. It is impossible for a hobbyist to work with SLVS-EC.

*avoid branches The blog post I mentioned: Paper: Parsing Gigabytes of JSON per Second https://branchfree.org/2019/02/25/paper-parsing-gigabytes-of... Another related post from Lem…

This is true on a few streaming application (such as parsing). And most of the speedup is because of tricks to avoid doing beaches. There is a great blog post from one of the autho…

CPUs with high power and high performance gets binned into mobile and iot sku. But those i9 ks sku can achieve a couple hundred extra MHz. But have a much higher base clock speed.

From a quick search, it seems to be due the Radon gas. Exposure to Radon is the #1 cause of lung cancer on non-smoker. Canada ranks third on indoor radon concentration worldwide.

Astronomical cameras and microscope cameras are affordable. Some of them mm support sensors that uses them even supports Sony's proprietary protocol. A lot of sbc boards support MI…

They can gather this data through other means...

It is hard to find yerba mate that doesn't taste stale outside of south of South America. Friends that drink it ask for people traveling to SA to bring them some. They are also ver…

Something I realized is that the dark patterns change from country for country. Brazilian websites uses patterns that aren't that common on American sites. All news organizations a…

This is probably intended for encoding webcam chat between Intel devices. They can hash the video "frames" to detect interception.

This is not new. It is news because it's from Intel. I looked into that a year or two ago and there were papers on the this. Anyone who is familiar with Euler Video Magnification a…
