Anything RF
A website called energy-storage dot news should not be mixing up energy and power
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…
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…
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…
Come be a DSP engineer. I take FFTs of IQ data almost every single day
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…
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.…
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…
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…
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…
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…
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…
The title sounds whimsical, but animals cause a significant amount of outages. Around 5-10% are caused by animals. When I interned at a power company I saw them install “squirrel guard” insulating equipment terminals
This is a classic security dilemma that is not easily resolvable. Suppose we just look at the US and China. Each side will discover some number of vulnerabilities. Some of those vulnerabilities will be discovered by…
If the money went to a bad cause instead of a good cause, the incentive to go to the gym would be higher
I can’t relate to that. When I see a banner ad I find it obtrusive whether it’s from Bank of America or my favorite HAM radio company. If I’m in the market for a product I value hearing the testimonials of people in my…
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…
This also seems generational to me. I’m an American younger than 30 and the only people at my company who embody this are the senior people over the age of 40.
What does it mean for an op amp to outperform an ADC?
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…
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…
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…
