My assumption is it's referring to mathematical tables and the historical makers of them. https://en.wikipedia.org/wiki/Mathematical_table

As a quick and dirty rule of thumb measuring parts per million in anything except time or frequency will get expensive. Temperature drifts will cause expansions and contractions on…

Yes fun story, Jack was an assistant signalman and got paid for the job, partially in beer! https://en.m.wikipedia.org/wiki/Jack_(baboon)

By 1870 pi was known to several hundred decimal digits, for something like this calculation where you have other large sources of error Archimedes approximation from 2 millennia ea…

Oxide makes a rack-scale computer called the Oxide Computer, here's the intro page: https://docs.oxide.computer/guides/introduction

That phrase distinguishes the internal group responsible for that part of the architecture, don’t think it’s a marketing term.

Could have been Earl Muntz, who was in the TV manufacturing business, learned about this from one of Bob Pease’ columns. https://www.electronicdesign.com/technologies/industrial/bo…

The explanation is really well done, it captures the essence of the Pauli exclusion principle without delving too deeply into the weeds. In my opinion the best part of the video is…

NREL has a great visualization for the research cell (as opposed to module) side of things here: https://www.nrel.gov/pv/cell-efficiency.html

Funny story, that demo only exists because the designer was mis-categorized as a software engineer after an acquisition by Apple. After nearly getting the person in question fired …

Was it this one perhaps? https://news.ycombinator.com/item?id=7261003

From the paper it looks like most of the interesting work with the laser and optical train use an external board to recreate the feedback and control circuitry already present and …

Neat hack, but why would you want a fan on the internet?

There's an episode of James Burke's Connections that explores this idea with a bit of depth, I recommend watching the whole series if you have the time. James Burke Connections, Ep…

With regards to how you locate it, the paper proposes looking at existing data from FERMILAT, a gamma ray telescope which could possibly pick up anihilations from a dark matter clo…

Arecibo is and has been used for radar astronomy as well https://en.m.wikipedia.org/wiki/Radar_astronomy

You can use the phenomenon of negative differential resistance to improve the design of some very common circuit elements. For example you can move from a classic six transistor SR…

This is a pretty thorough description of generation, not just the classification problem that is the usual introduction to machine learning. I just loved the map of the generated p…

Link to the other HN thread on this topic: https://news.ycombinator.com/item?id=5391667 If the comments are to be believed someone's already lost their job over this.

Unless the planets happen to orbit very stable stars in the plane that sometimes puts them between earth and their star. With Kepler and some earth-bound telescopes you can discern…

I use Better Touch Tool [1] which is mostly about expanding defaults for multitouch gestures. I haven't gotten around to using the Better Snap tool which focuses on window manageme…

That's exactly the application they're after. When these discussions happen I like to calculate some hard systems numbers since they're rarely in either the literature or the popul…

Trace amounts perhaps. Generally speaking radiative heat scales as T^4 where your temperature is measured on an absolute scale like Kelvin. In addition most of the heat flux being …

If you want to implement it in a general way you still need to know how javascript supports closures though.
