Nope. The actual archeological community has called him out over the years. I’m assuming he’s in it for the money. https://ahotcupofjoe.net/2022/12/ancient-apocalypse-summary-of-the-series-from-a-professiona

Why is it that he dismisses the ability of each of the native cultures (Mesoamerica, Egypt, China, ...) to have developed their own technology? His fundamental thesis is that they couldn't . That thesis comes from pseudoscientific 19t

Well; except for the fact that the 1.5TFLOP quoted in the article is because of the AMX part. The actually useful throughput of the big-core is probably more like 35GFLOP peak . This compares to the 1–2TFLOP throughput of the GPU. The CP

That's how we felt when we were writing the software rasterizer for Larrabee! The issue is that that 1.5TFLOP is probably way more power than the M1 GPU's ~2.5TFLOP. The second issue is that a SW rasterizer is going to spend ~50%

The 7 day week is a fairly modern convention; I believe popularized by the Christianization of Europe. The classic Roman "week" is 8 days. The Mayans (and most of mesoamerica) used a pair of interlocking 13 & 20 day "week

I can't tell if you're serious? I'll take your comment at face-value: Graham Hancock is not a trustworthy source. His "inspiration" is based on thoroughly discredited, white supremacist garbage. The fundamental thes

I'm not so sure. The whole point of an exercise like this is to demonstrate power, or to acquire resources. Neither tactical nor strategic nuclear weapons would help with those objectives. Ukraine's army isn't isolated to a s

I was chatting with my Uncle (ex-USGS) about this a few years ago. You're going to need ~1m data to resolve a carrier's heading. You'll need something in geosynchronous orbit. If your CCD is 100mpx, then you need 10000 acquir

Walking off the lot got me into the craziest argument I ever had with another human: I went to Maxwell Ford, in Austin, (2018) and asked what the cash cost of the base model Explorer was. These are practically "no options" vehicle

The US foot has always been defined by the meter. Originally, Thomas Jefferson set the foot to be exactly .3 meter. The science of surveying and measurement weren't great in the late 18th and early 19th c, so the definition of the mete

Also, in practice, no one cares how "tall" the chip is — 100nm vs 200nm is ... unimportant. The result is that the volume of the poly hasn't changed much in the last ~10 years. Transistors are still biggish; just with tiny

It’d be nice if, when I logged in to a site, my browser would casually mention if the pw is reused, or not. Now-a-days, I just habitually check my pw on login to make sure it’s random. For the SO & kiddos, I manually reset all the finan

Compactness and timing. I don’t know why picosecond switching is a big deal, here? A 3Ghz part with a transistor depth of 40 would require a top end switching rate of 8 picoseconds — and that’s really going to make PD unhappy, as it’d lea

I think a "compiler" isn't too bad — certainly easier than an IDE by a long margin. An optimizing compiler OTOH, can be a bit of a beast. Because the optimization passes self-interact, on every line of code, repeatedly, any

Geometric algebra (GA) is a structure you add on top of a regular vector space. It was repopularized by David Hestenes in the 60s and 70s as a different method for describing spacetime (for physics). The basic observation of GA is this: in

Hopefully we'll get a drive by: is there a chart showing the relative distribution of elements on, say, a weakly logarithmic scale, overt time? Like: 0 — 98% H, 2% He, 10^6 ..., 10^7 ..., ..., now.

My understanding is that it's a Faustian deal: YT is indemnified by removing its own agency in this regards. If it just follows the rules , it gets a pass. If it interprets the rules it doesn't.
