Simple is not available in Canada, which is what the above poster is referring to. Few (no?) Canadian banks offer email notifications for debit (Interac) transactions.

Yep. This is going to be the next cold fusion - the device will soon be debunked, but we will still be hearing about it from conspiracy theorists for decades.

Avoid the new gTLDs. Most are mismanaged crap. The gTLD system was the greedist and worst decision ICANN ever made.

Stick with tried and true domains - ideally .com, but your country's ccTLD is another good choice.

The consensus standard for this sort of test is IEEE 1528, and you are absolutely correct. The test uses a gel phantom (the standard provides a few formulations for different frequencies but most are a mixture of water, salt, sugar, and a thickener) and it is poked at with a sensitive probe to measure local temperature rise.

Agreed! But that wasn't the message that Bay Street took from it.

There's no contradiction. Two things are happening here.

Foreigners in the US (H1B applicants) are heading up to Canada because the immigration policies are more lax.

Canadian citizens from Canada are heading down to the US because the salaries are higher, and under NAFTA Canadian engineers qualify for an easy-to-get instant visa (TN status).

That already happened, to a degree. Canada's dot-com darling was Nortel, which at peak accounted for 1/3 of the total valuation on the Toronto Stock Exchange.

Then the bubble burst and Nortel collapsed. A lot of institutional investors swore off tech after that, and it hasn't really rebounded.

It was not the Bay Area, he was working in Seattle.

I think it's more a case of VCs not being calibrated to the real cost of doing business. Canada is a first world country with a GDP per capita not much less than the states. There is plenty of wealth available that could be invested in tech. It's just Bay Street generally doesn't want to, because they don't understand the tech business.

Name one prominent Canadian VC firm - I can't think of any, and I'm Canadian. But ask me about US firms, and I can name firms like Sequioa, a16z, and BVP. We don't have that here.

If Canadian companies were willing to offer a competitive salary, maybe Canadian grads would stay. It doesn't even have to be 1:1 with the US, even 75% would be nice.

As it is, there is little incentive to stay here. I know a new grad who was faced with the choice of staying in Canada to earn $40-50k CAD per year starting, or heading to the US where he had a job offer with one of the big five for $120k USD plus signing bonus. Guess which option he chose?

Canadian tech companies love to complain about lack of talent, but they're not willing to pay for it, and they seem oblivious to the fact that we have a professional worker mobility agreement with our southern neighbors that makes it very easy to get a visa.

Something's gotta change.

> But USB-C isn't limited to 5V, power delivery is at 20V. That might explain what's going on here (since the user reports 20V on the output) - it thinks that the peripheral is a power hungry device and it's trying to charge it. That's a problem, but it could be that the peripheral is poorly designed and is mistakenly asking for power that it can't actually handle.

This was my interpretation, the host sets the output voltage to 20V incorrectly (due to a software bug or a hardware failure). Putting a crowbar circuit defensively on the peripheral side would save the peripheral.

As an electrical engineer - I think incidents like these are a pretty solid argument for incorporating overvoltage protection into 5V USB peripherals.

Even something as simple as a zener clamp with a polyfuse to make a dead-simple crowbar circuit will save a device and won't contribute a whole lot to BOM cost.

Ultrasound processing is actually pretty niche: you have a whole bunch of channels with a very high sample rate (tens of MHz). In the case of medical ultrasound, a typical handheld ultrasound probe can have range from 50 to 150 parallel channels.

Because you need fast, parallel DSP, FPGAs actually really shine for ultrasound. And because production volumes are relatively low, the NRE to jump to an ASIC generally isn't justified. Just about every modern ultrasound machine does signal processing on an FPGA.
