The privacy of EU persons coming in from a non-EU IP address still need to be protected under GDPR. This solution is a start but it's not bulletproof. Edit: I don't want anyone to think I believe it's a good start but it is

It's used that way on highway signs in England, where it's very confusing.

The effect they're measuring, in this case, is the weaker gravity field at the top of a mountain, less than the field intensity at the Earth's surface. So the clock ticks faster in the weaker gravity field.

Hi Nick! I'm still working on certification and guards, but in a very early stage company now. Do you know I can predict and (sometimes) control the progress of certification testing of cross domain solutions? That was my PhD. Now I&#x

In the early 1990s when we did this research, it was mostly RS-232 devices; the designers did in fact often connect LEDs directly to the serial TXD and RXD lines, which are relatively high voltage and have plenty of drive capability. Garden

I have first-hand experience: Around 1999, I wrote a paper about information leakage from blinking LEDs on devices (one DES link encryption box, used by banks, for example, was sending out plaintext on the LEDs). I was working for a defense

It's pronounced like "cock". It's named after the animal, and that's how you say it in French. It's how people who use the tool say it.

I didn't know that. Thanks! Also: Second, thermal radiation, as usually defined, also disappears. There is no longer any air for the blast wave to heat and much higher frequency radiation is emitted from the weapon itself
