I’m not familiar with any HF comms channels other than military or broadcasting that get 20 kHz of bandwidth. Most HF modes get 3 kHz. You might be able to get 5 kbps at 3 kHz BW with some modern modes that can adapt to the frequency select

He’s giving advice about generic protocols - you could learn about them and make your own decision. The tools he mentioned are open source - you could read the source code or trust in the community. I don’t know what other guarantee you cou

Spacex rocketry tech is subject to ITAR regulations. That restricts who they’re allowed to contract with, data encryption and handling, but altogether those regulations are quite bare. It likely wouldn’t be enough to stop a state actor or r

Do you mind sharing what industry you’re in where you can fully rely on FOSS? In my industry we’re dependent on MATLAB, Xilinx tools, closed source embedded software and more. To name a few industries: game devs might be stuck with unity, f

If a contract requires RJ45 terminated Ethernet patch cables and the contractor delivers keyed RJ45, they have not delivered because RJ45 doesn’t even have the correct conductor layout to act as an Ethernet cable. Contracts call for RJ45 al

Well you definitely SHOULD say RJ45. We do a lot of networking at my job and if I asked for an 8P8C connector, I would get confused stares. Say Ethernet cable, Cat 6 cable (or whatever cat), or RJ45. Sometimes being correct isn’t the right

They can make advanced chips in Arizona, but the bleeding edge is in Taiwan. Arizona can make TSMC’s 4nm process, but in Taiwan they’re doing 3nm and ramping up 2nm.

I imagine many people in 1970 were incredulous that we’d have transistors with 20 nm pitch width.

I agree, and I think most people would say the current models would rank low on creativity metrics however we define them. But to the main point, I don’t see how the quality we call creativity is unique to biological computing machines vs e

To the extent it’s measurable, LLMs are becoming more creative as the models improve. I think it’s a bold statement to say they’ll NEVER be creative. Once again, we’ll have to see. Creativity very well could be emergent from training on lar

AI can’t do our jobs today, but we’re only 2.5 years from the release of chatGPT. The performance of these models might plateau today, but we simply don’t know. If they continue to improve at the current rate for 3-5 more years, it’s hard f

We’re talking about spending a couple of hours learning the basics of negotiation for a likely 10-20% increase in salary/equity. That’s certainly not making the difference in solving the world’s problems. If you’re speaking more broadl

It sounded anecdotal because I shared an anecdote. I don’t have a research study on the topic. Still anecdotally, I’d say the same thing about my 3 internships, so I’ll say n = 4. Happy to hear your anecdotal experience or non anecdotal da

According to the paper, this worked because the dielectric change from all other blood diagnostics was negligible, allowing glucose to be measured. Gluclose in blood is around 80 mg/dL. It may be possible to measure other blood chemist

Yes, it is sub optical RF sensing. The important factor here is that the gluclose blood capacitively couples to small sensing antennas. The sensing antennas are resonant elements, whose exact resonance changes depending on the surrounding e

It sounds more complicated than it is. A metasurface is almost always just a fancy patch antenna. If you reduce some parameters down, you can really just view it as a resonant circuit. You could design a meta surface in a few minutes in any

During the Soviet Union the ethnic Russians came from Russia, lived in the large cities, had most of the high paying jobs and then left when Kazakhstan had their independence. They were colonized and now they have their own country.
