You make HBM by stacking a whole bunch of dies on top of each other. The signals from the upper dies need to pass through vias in the lower dies to get out - taking up valuable die space in a way which simply isn't needed with regular

This is already happening, by the way. SK Hynix's new Cheongju M15x fab was originally intended to be for DDR, but mid-construction they shifted it to HBM. Similarly, the Icheon M10F packaging line has been retooled to HBM, allowing it

Rather the opposite, actually. With the rising living standards and a looming population cliff due to the one-child-policy wages in China have steadily been rising - and they'll get even higher in the future. Any Chinese industry relyi

It's a $1 MCU, which will get embedded into a $50 device. If you're a company selling a cloud-plus-device product, then that 250k tooling cost and not-exactly-trivial attack process will be quite effective at stopping Chinese clon

Most attackers aren't nation states, and your security shouldn't rely on obscurity anyways. Having to attack each individual device and having to get specialized equipment to do a highly-skilled attack breaks the vast majority o

Not really. The RP2350 just adds some bog-standard security features the ESP32 family and plenty of others have had for ages, that's all. The goal of the bounty is to demonstrate that they aren't just a company making toys for h

A Yubikey is basically a single chip and a bunch of plastic. At their $50 price point, there's plenty of room for some chip manufacturer to skim off a couple of dollars per chip to add an additional metal layer for a tamper protection

Yup, four cores. No crazy muxing needed because only one kind is ever active at a time and the other kind kept in reset, so there's no need to do any runtime arbitration - basically just a dumb switch on few dozen signals. The bonus RI

More specifically: it sounds like something which was supposed to be an atomic operation was split into two by the preempting task, with corruption happening because that task also interacted with the same piece of (now-temporarily-invali

Those are "reinvent the world" level of changes. We're talking about an industry where nothing is standardized, and you want to rely on highly formalized documentation!? I'm not exaggerating when I say that "which

Roundabouts don't need any expensive control electronics, and have very little upkeep. In the long run they are likely cheaper than traffic lights.

That's just traditional design failure. A well-designed road network has higher-speed through roads and lower-speed local roads - and a school (serving the local neighbourhood) has zero business being near a through road. And to make

Depends on the roundabout, actually. With a turbo roundabout[0] the lanes form a spiral rather than a circle, so you are automatically forced to the outside and doing multiple turns is physically impossible. [0]: https://nl.wikip

I live in The Netherlands and roundabouts work just fine. Other European countries seem to have very similar experiences. Is there something unique about American drivers or traffic engineers which makes them incapable of handling the conce

They are also better for cyclists. Take a look at [0], for example: the pedestrian crossing forces an early stop for cars entering, and there's a neat one-car-sized waiting area for cars leaving. They both reduce the sight angles betwe

Perfectly fine, actually. For example, the one at [0] regularly sees bendy buses[1] traverse it without any issues. The trick is that there's an outer ring of asphalt and an inner layer of paving stones: cars the asphalt as it is far

Counterpoint: all of the identity-verification flows I have experienced in the last few years used NFC to read the chip in my identity documents - from car rental apps to my bank doing KYC. If anything, verifying NFC is easier than imag

A similar hijack will soon(ish) become impossible, as the current train protection system will be replaced by ERTMS. Basically, the current system works by injecting a small current signal on one rail and trying to sense it on the other rai

Stopping traffic on railways isn't much different from stopping traffic on highways, is it?

Stop, not derail. The saboteurs aren't physically damaging the railways: they are shorting the rails together , causing a fake train to be detected. But indeed, XR is the least likely subject. They have stopped trains before, but th

Climate activists are definitely known for disliking fossil fuel plants - and there's one directly next to that. I could see an activist naïvely thinking that this would sever that one power plant from the grid, making a clear anti-f

Russia isn't the only group interested in doing terrorism in The Netherlands. Recently the Farmers Defense Force and Extinction Rebellion have caused far greater disruption. Could it be Russia? Obviously. But in my opinion the odds are

It is indeed possible Russia is behind it, but considering a domestic farmers' terror group has told its followers to cause disruption today (as it is a politically-significant day), and those are definitely disrupting highways, ch
