AI Thread Summary
The discussion centers on a memory of a video showcasing an FPGA-based computer system's resilience, where it continued functioning despite being shot at. The original poster is seeking details about the video and the company or research group behind it, noting that it predates YouTube. A participant recalls a similar concept from the 1980s involving Tandem, which marketed a "bulletproof computer" that could recover from hardware failures by using redundant circuits. This historical reference highlights the longstanding interest in the robustness of computer systems. The conversation reflects a blend of nostalgia and curiosity about advancements in computer durability.

Haven't been logging on to the ol' PF as of late, but I'm hoping that one of you may remember more details about something I seem to recall.

Probably a good 5 to 8 years ago, I recall there being a video somewhere (this preceded YouTube!) demonstrating the robustness of an FPGA-based computer system (as I recall). The video had a picture of a guy taking potshots at a board with a rifle or a shotgun, and with the claim that the computer was continuing to chug along and (if I recall correctly) and with the display continuing completely uninterrupted.

Would anybody recall the name of the company or research group behind this, or better yet, the video itself? My Google-fu is too weak to come up with anything, so perhaps I'm merely re-imagining the printer scene from Office Space?

So this question is 5 years old, but here goes...

You may be remembering something rather a lot older. In the 1980s, the computer manufacturer Tandem used to advertise a "bullet proof computer" because litreally every circuit occurred twice, and the oprating system retained enough history on its I/O that it could restart all th e running processes from the "other" malfunctioning processor if it was damaged. They would actually shoot their computers at trade shows (apparently, I never witnessed it) but it wwas considered pretty cool stuff at the time. (I was working at a database software outfit at the time, and getting interprocess communication (for db synchronization) was particularly complex in that computer)

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
