I had a teacher in the early '90s that said the Japanese were the best at reinventing things. They would take something, study it, and remake them better.
> However, in reality, not only does the carrier not mind if the phone keeps being used (as long as it’s on the carrier’s network) but the lock doesn’t expire once the customer pays off their plan.
I recently paid off my AT&T iPhone X and the process to unlock it couldn't have been easier.
I buy my honey locally in south Louisiana, they're usually in generic Mason jars and can be found in places like hardware stores and barber shops, from local bee keepers.
What the heck is "fancy" honey? Did not read the article.
We did this in the Navy to check circular wave guides to the ECM antennas in the leading edge of our bombers wings. We had to do this once every 6 months (I think) with a sweep generator to see if the cables needed to be replaced. Also, installing these were a complete PITA! Nothing was a straight run to where it needed to go, so you had to bend them as gently as possible as you fed the new line into the wing. Then you had to test it again.
These were very expensive and I've seen more than a few screwup's while installing them.
A coworker's cat-5 tester also has a TDR function that shows you where an issue is on the line.
There was several different programs the ECM would use and this is the only one I can remember at the moment.
When I went to the ECM school on the system, the first part of the class was listening to pilots being chased by surface to air missiles. The class was in a little building and it was Top Secret classified at the time. We could take notes, but they were locked up in a safe and we couldn't take them back to the squadron.
When I was in the Navy (1977 ~ 1981), our A-6E was equipped with an ECM suite that was designed to intercept and process pulse signals, automatically select the optimum countermeasures technique, and then apply the technique. One of these countermeasures was to send a return signal back to the radar, "telling the radar that the aircraft had accelerated (beyond the speed of light) and was now on the opposite horizon. The effect of this was reported to be a snapping off of the radar mast or tipping over of the mobile trailer the radar was in due to the torque of the radar dish moving to the new location.
