claims a processor base speed of 3 600 000 000 GHz (= 3.6 Exa Hz)[/QUOTE]I'm sure the figure is completely accurate. Seems reasonable. Of course after running at that pace for a million cycles the thermal protection circuit engages and reduces it back to 3.6GHz to prevent the system from boiling itself away.

[quote]The FDA says that the products have been hard to scrub out because of claims on social media, where the drinks are promoted along with false health information. Most of the claims can be traced back to Jim Humble, founder and “archbishop” of the Genesis II Church of Health and Healing, aka “The Church of Bleach.”

Humble has been touting the solution for nearly two decades, referring to it as MMS—Miracle or Master Mineral Solution. (It’s also known as the Miracle Mineral Supplement, the Chlorine Dioxide (CD) Protocol, and Water Purification Solution (WPS).) Humble is a former Scientologist who reportedly claims to be a billion-year-old god from the Andromeda galaxy.[/quote]A [i]former[/i] Scientologist? Wonder whose decision [i]that[/i] was.

Perhaps it is his apprentices or acolytes that recommend applying bleach externally to dry up poison ivy rash. Bleach is about as good for your skin as it is for your innards...

"Vaping" has been touted as "less-bad" than inhaling the smoke from burning tobacco. [url=https://www.chicagotribune.com/lifestyles/ct-life-vaping-illness-death-illinois-tt-0823-20190823-s27xqukusfdi7edxjpt6k5e23e-story.html]Really? You sure about that?[/url][quote]The Illinois Department of Public Health announced Friday that an adult resident died earlier this month, but would provide no further identifying details, or circumstances surrounding the death. The patient was one of nearly 200 across the country hospitalized between late June and this week with symptoms including coughing, shortness of breath and fatigue, and who reported using e-cigarettes, health officials said. In Illinois, the health department is investigating 22 of these cases, and possibly 12 more. The patients are between 17- and 38-years-old, and some also experienced vomiting and diarrhea.[/quote]

[QUOTE=ewmayer;524454]Only if you can also get the Exahertz memory needed to keep the CPU fed. Does Office Depot carry that as well? If not, you might have to try Newegg. ;)[/QUOTE]The SYSTEM advertised by Office Depot includes ram. But one can find almost anything on eBay. And wouldn't an ExaHz processor include a multigigabyte 4th level cache? :]

One that Edison skipped?
 
On the way to finding an incandescent lamp construction that would last hours, he reportedly tried thousands of things. I'm guessing he skipped this one. [url]https://en.wikipedia.org/wiki/Glowing_pickle_demonstration[/url]

Edison tended to favor electrocution of larger objects, notably during his vicious [url=https://en.wikipedia.org/wiki/War_of_Currents]disinformation-PR campaign[/url] against Westinghouse Corp, which was licensing and developing his former - for a brief period - employee Nikola Tesla's AC-based technology.

AC. The executioner's current.

[QUOTE=kladner;524525]AC. The executioner's current.[/QUOTE]
30ma AC, or 300+ma DC to produce fibrillation. Edison had a point. [url]https://en.wikipedia.org/wiki/Electrical_injury#Pathophysiology[/url]
As I recall, 50-60 Hz is near the maximum physiological damage frequency.
Military gear uses 400 Hz for compactness.

True, but the disinformational aspect of Edison's pitch was the implication that "safer DC" was even a choice - it wasn't, it simply did not permit large-scale power transmission and distribution at a reasonable cost. Given that electrification was an unstoppable societal imperative at that point, the true issue at hand was how to make it as safe as possible, and it was obvious to anyone who had a basic understanding of the tech that virtually all the associated accidents and fatalities were due to improper wiring and installations made by unscrupulous operators. The current-wars Wikipage:
[quote]George Westinghouse was suddenly put in the role of a "villain" trying to defend pole-mounted AC installations that he knew were unsafe and fumbled at reporters' questions trying to point out all the other things in a large city that were more dangerous.[97][96] The next month he did better in his response printed in the North American Review, pointing out that his AC/transformer system actually used lower household voltages than the Edison DC system. He also pointed out 87 deaths in one year caused by street cars and gas lighting versus only 5 accidental electrocutions and no in-home deaths attributed to AC current.[96][/quote]
As with all new tech, there were dangers and something of a learning curve - the sensationalist press of the day of course only focused on the dangers. The number of lives saved simply from elimination of gas lighting was more than the accidental deaths already in those very early days. Not to mention the lives saved from having widespread electric refrigeration (i.e. safer food storage), electrically lighted and powered hospitals, etc.

I have ews or in one case heard that 240 vac is hard to turn loose of if you grab onto it. A brother of mine had such an experience, and was able to upset the ladder he was on. This broke the circuit, and may have broken ribs when he landed on stairs. He was moving bent and painful when I saw him shortly after.

He was rigging audio cable through the suspended ceiling over a night club. He was using a long metal rod with a clip on the end to drag cable through when he ran into something that someone had left exposed.
