    That's a Nintendo Switch. The general purpose docking OS was what Win8 was supposed to be but it was flubbed horribly.

    It's worth noting that this isn't new technology. This paper is specifically about how their new technique provides a small but statistically significant improvement on existing te…

    Decades ago there was a huge push to green up cities by planting trees everywhere possible. A couple of decades after that there was a huge push to remove trees because of infrastr…

    This is as good as when the engineer from the Claude team said they load their website in such a way as to protect against hostile actions such as scraping.

    Gotta love how they moved the "Create Email/meeting" buttons in Outlook mobile and stuck the Copilot button there so that you will hit it accidentally.

    We have some special cases I can't go too much into that lend themselves well to rolling our own and stripping things down as much as possible.

    It's an interesting case to me. The company I work for has been shipping systems on windows since the 90's despite pretty consistent requests from customers to ship hardware on Lin…

    Yup, a lot of scopes actually did this internally and some still do. It's part of why some scopes lose half their BW when you go from 2 ports to 4 ports (some go the other directio…

    If you are an absolute nutcase, you could characterize a set of line stretchers and a multiplexer on a high end VNA then offset the inputs of the 4 channels on that UXR with them, …

    Keysight at least, has a fab where they make their own ADCs. Those are something like ENOB 6, 10 bit raw up to 120GHz and are used in their oscilloscopes but can also be purchased …

    It's technically not a signal generator but an Arbitrary Waveform Generator. It provides a base-band modulated signal to the signal generator which the sig gen upconverts to the RF…

    In the simplest possible terms, EIRP is the equivalent of power density. It takes into account how narrow the beam from your antenna is.

    Yotta marketed itself as a "bank" where every time you deposited to savings you would get a free lotto ticket for the month based on how much you deposited. They did this by offeri…

    Force cannot transmit through the material faster than the speed of sound and because fundamentally at a subatomic level, mechanical force is the interaction of electromagnetic and…

    There used to be some pretty wild published advice on how to use a radial arm saw including ripping full sheets of plywood by walking the sheet across the cutting plane with the sa…

    Bosch did release an actuator-based solution. They got sued by SawStop for patent violations and lost and pulled it from the market. SawStop's main patent just covers the concept o…

    They offered to relinquish one important patent, but they have a huge portfolio of patents covering blade breaks specifically applied to table saws. If you go look at the actual te…

    This is coming out of Australia so it wouldn't be ITAR, but they do have their own export restrictions on this sort of technology.

    This is very similar to current military optics. It just uses a GaAs meta-material surface instead of a GaAs microbolometer array. Fundamentally they are both semi-conductor micros…

    Not a strictly new technology but an improvement on existing concepts. This is building an artificial non-linear optic using a metamaterial to make it more compact. It works by fre…

    Said another way, you're making a filter. Zeroing out FFT bins is a brickwall filter. Brickwall filters have poor frequency and amplitude accuracy if you are trying to preserve the…

    I was replying specifically to the "It doesn't matter if we just make enough" idea. For solar panels on a site scale you can use variable pitch panels focused on a solar collector …
