What the author is describing is the logical conclusion of the Bitter Lesson applied to software development. To quote the essay: "We have to learn the bitter lesson that building in how we think we think does not work in the long run.

I think the miserable state of cellular modems ultimately comes from the power dynamics of private spectrum. The 3GPP protocols are complex because they're not really beholden to the implementers, but rather to the network operators. T

Sure, but the probability would be low-ish of that happening, and the other system could either switch frequencies or beamform a null in the direction of the interferer if they were also a phased array. Maybe the EIRP shouldn't be unli

I feel like limits on EIRP are overly conservative and restrict the usefulness of phased arrays. If the limit were on total radiated power, then your 1 watt WiFi router could have the range of a kilowatt transceiver with a reasonable number

Good point. To my knowledge most of these radars are MIMO, which are more capable than phased arrays but it's a different architecture. Also these radar systems usually have on the order of 10 antenna elements (although this number is

Starlink doesn't get enough credit for their phased arrays terminals, I think. They've managed to make a performant antenna for 10 to 100 time less cost than the competition. Without that, the whole system wouldn't be such a

Having just skimmed the linked tutorial, it looks like GFlowNets could be useful for automated theorem proving. Anyone with more knowledge know if this is possible?

It's easy to see how this advice applies to a SaaS company, but what about a more capital-intensive startup? Like a startup with an innovation in manufacturing, energy, telecoms, how do they have leverage when approaching investors, es

Not only that, but the matrix scanning could be done via interrupts instead of via polling as is typically[0] done. An interrupt could fire on a level shift of any of the column GPIOs, then the MCU needs to search the rows to find the selec

Would this have been possible outside of the Bay area? Is it possible to raise this amount of money for just an idea (a good idea from a knowledgeable founder, but no POC or traction) elsewhere in the US or anywhere in Europe? From what I u

Both great points. Regarding your second paragraph, note that this isn't so bad for multi-core processors. For randomly scheduled processes, the (expected) maximum response time is the maximum time between yield points divided by the n

I've been wondering recently to what extent formal verification could be used to simplify CPU hardware and ISAs. For example, MMUs are unnecessary if the OS verifies that all programs only access memory that's been allocated to it

Ah good catch! The reason I thought the patent was assigned to the Smart company was because they list it in their Wefunder page[0] (under the heading "Key Accomplishments"). But actually all that's stated on that page is tha

So the article says the technology was developed at NASA and then licensed to Smart via the "Space Act Agreement". It looks like the company has three patents already, one of which[0] seems (to me, after a brief glance) to cover t

Can someone explain how block timing works in proof-of-stake systems? As I understand it, with proof-of-work the mining difficulty increases or decreases to maintain that each block is found in roughly the same amount of time. In proof-of-s

Exactly. I wrote this explanation, but you beat me to it, so I'll just post it here: The real reason we use I/Q sampling is because we want to frequency-shift a signal. Why do we want to frequency-shift a signal? In radio frequenc

Could you give some examples of such critiques? The idea seems interesting and I'd like to read a more long-form argument.

I'm in the same boat as well, and I'm also questioning whether this mindset is something that is best to fix (e.g. through therapy), deal with ("suck it up, work isn't meant to be enjoyable"), or work with (by findi

An open source WiFi chip would be super cool. I wonder how easy it would be to take the FPGA code from openwifi[0] and combine it with a radio on the same chip? [0] https://github.com/open-sdr/openwifi
