A live test would be quite dangerous if the microwave does leak EM.

Actually, this is not as stupid as it seems. I was first baffled by the idea that a website can read the RSSI of the device I'm on, then I realized its probably just measuring the latency by pinging every second.

This is why if you want complete determinism, use VHDL. Unlike verilog, VHDL was developped specifically for describing hardware behavior.

Before the 2000s or the Agilent spin-off, HP was the undisputed king in electronics test equipments. Their flagship multimeter HP3458a, launched more than 30 years ago, is still the standard in metrology. And Keysight (spin-off from Agilent) is still making them with little to no significant modifications over the years.

They also made some great RPN calculators.

More importantly, because of the low-power requirement, LPDDR typically have better binned dies than DDR.

Be careful, this isn't something you should talk about/admit in public at all. Feds really don't like it when people mess around licensed bands.

Okay, but its not very useful is it? Sure, you can propagate the state vectors directly, but even tiny amount of noise may be amplified and can make the results useless. Also, read up on why Euler Method is bad for solving ODEs numericaly.

This is exactly why we use Kalman filters.

The actual power of Kalman filter lies in its ability to estimate states/variables that can't be measured directly, not just filtering time-series data.

With Kalman filter, you not only get your output filtered, but along with the state of the system at each step as well. No amount of low pass filtering can achieve that.

Should add "Moskowitz" to title. Right now it looks like UC Berkeley's official statement.

Emphasis on bias. Though factual, the words used by the website are heavily loaded and clearly serve a purpose.

Just because its an industry front doesn't mean it treats (take money from) all companies equally.

And the fact it calls Tylenol out rather than its generic name acetaminophen just adds to this.

If you just want to know if a usb cable can safely delivery a certain current, then a cheap multimeter might do.

If you want to test whether a cable will work with a certain protocol at a certain data rate, just plug it in and see if it works. Because the alternative method[1] costs hundreds of thousands of dollars.

Be careful though, ATX power supplies don't have a crucial feature that bench supplies do: setable current limits. They will pump out as much power as they can to maintain the output voltages until they saturates.

Which can result from releasing some magic smoke if you are lucky, to a call with your insurance company.

I am pretty sure M.2 uses 3.3V exclusively, and depending on the implementation, RAM sometimes gets its power from down regulated 3.3V as well.

Though you do have a good point, nobody misses -12V and -5V.

Probably non-existent since the thickness of insulation layer isn't controlled.

Surprisingly, silicone rubber has a dielectric constant between 2 and 4 [1], which is pretty close to FR-4's 4.4. So maybe it isn't impossible?

...which puts all the DC conversion on the motherboard.

Honestly, I can't tell if this is a good thing or a bad thing.

On the plus side, power supplies will be much simpler to design and test, with potentially better efficiencies. On the other hand, all those additional DC-DC converters will take up quite a bit of space on the already crammed boards, and now you got more heat to manage.

Forever sitting in your wallet, because its an "investment" and cannot be spent normally?

Just positive feedback loop. The term "positive" or "negative" refers to the effects of the feedback path on the overall system, a negative feedback loop attempts to negate any changes in the outputs, while a positive feedback amplifies any changes.

I believe that is highly illegal in many countries. Here's what FCC has to say about jammers: https://www.fcc.gov/general/cell-phone-and-gps-jamming

From my very limited knowledge of physics, time crystals can theoretically oscillate forever without any excitation at their ground state, though laws of theromodynamics are not broken and energy cannot be extracted from their oscillations. In a normal crystal oscillater, power is needed to keep the crystal oscillating.

The amount of astroturfing in the reddit thread is just awful. VPN hosters market in the most aggressive ways possible, probably due to the fact that its usually impossible to verify a VPN hoster's claims (without a breach), so assuming they did most of the VPN stuff right, any new users they lured in are gonna stick, at least for a while.

Yes. In addition, wafer size is another important metric of fab capabilities aside from process node, since it roughly translates into production rate.

Chinese here. A good place to start would be 知乎，zhihu.com, or chinese quora. I'm by no means skilled in mathematics(still an undergraduate after all), so there could be some more specialized websites/forums I'm missing here.
