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 selective non stationary channel.
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 could hope to get. If he told you he’s an anti digital censorship expert he could just be lying to you. Anyone COULD be an agent, but at a certain point you have to choose to trust people, at some potential risk to yourself.
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 rogue employees.
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, finance quant devs might be stuck with Bloomberg terminals, iOS app devs are stuck with apple’s tooling etc… this isn’t just an LLM problem IMO.
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 all the time and there are no mixups. You’d probably find it quite difficult to even find vendors for keyed RJ45
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 thing to do.
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 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 electronic computing machines. Maybe one day we’ll conclusively declare creativity to be a human trait only, but in 2025 that is not a closed question - however it is measured.
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 large datasets. But also it might not be. I recommend not speaking in such absolutes about a technology that is improving every day.
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 for me to see how human input would be useful at all in engineering.
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 broadly than just salary negotiation - I’d just say that humans aren’t perfect machines. We care about solving problems but we also have desire for money, power, status and following random rules.
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 both countries, some just by one party. If the US discloses every vulnerability, we’re left with no offensive capability and our adversary will have all of the vulnerabilities not mutually discovered. Everyone disclosing and patching vulnerabilities sounds nice, but is an unrealistic scenario in a world with states that have competing strategic interests.
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 life rather than an advertisement.
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 data.
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.
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 chemistry metrics that are similar in concentration at other frequencies, but there’s a lot of blood tests, many of which would probably be impossible - like white blood cell count, anything enzymatic, something whose concentration is measured in ug/dL, or something that has no effect on dielectric properties of the blood. I wouldn’t expect to see a whole blood panel via wearable radar anytime soon, but we may get a few more tests from RF sensing.
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 environment, in this case gluclose in the blood. You can then transmit an RF signal to the antenna, then record the signal reflected from the antenna’s port to estimate the gluclose level.
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 pcb design software and get it fabricated on low tech PCB fabrication equipment. In this case, they used an array of a specific type of patch antennas (that’s a meta surface) called the complementary split ring resonator. In a sense, all split ring resonators are “micro radar” surfaces, because a split ring resonator is designed to be electrically small compared to the wavelength. The researchers here found that the change in glucose in the bloodstream changes the dielectric properties of the bloodstream, and the resonant characteristics of the complementary split ring resonator change depending on the surrounding dielectric (a dielectric just describes the electrical properties of a material - for instance, a higher electric dielectric constant will slow down the phase velocity of an EM wave, which leads to various measurable effects in an RF system). Looks like great engineering work here, but I’ve always thought the term “metasurface” was foo foo jargon since I first began studying antennas.
Noam Chomksy’s critique is that the advertising industry’s main goal is to ensure that uninformed consumers make irrational choices. Essentially it undermines the market, due to the fact that in theory markets are efficient when people make rational decisions. Subject to advertising, people may pay more for a lesser quality product.
One would be Karaul. It was partially evacuated but a group of locals was designated as group of Guinea pigs for testing. And remember, this dust traveled for many miles. This is the Steppe, so dust gets picked up and travels with little vegetation impeding it.
With all due respect, I think you should read more about this instead of acting like I’m spouting nonsense, when you clearly know little about this topic. I have been to Semipalatinsk and seen their exhibit on victims to nuclear testing and I’ve read the literature.
They had civilization. The Islamic golden age touched Central Asia, The Silk Road passed through Central Asia, bringing wealth and ideas to the region. The people of the Kazakh steppe were largely nomadic but they had civilization. The Russians came and forced them to live in cities and work largely non-arable land. The Russians certainly kick started their process of industrialization, but they had civilization.
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.
You’re mistaken. They purposefully didn’t evacuate villages so the doctors could study the health effects on unknowing citizens. The radioactive dust traveled for miles and miles. Semey, a medium sized town near the test site had skyrocketing cancer rates and birth defects. The number of people affected is measured in the hundreds of thousands. Read “The Atomic Steppe” if you want to learn more.
