AI Thread Summary
A broken fax machine issue was resolved after replacing a 20 ft cord with a 5 ft cord, as indicated in a manual that recommended not exceeding a 6 ft length. The discussion centers on the limitations of RJ-11 (phone jack) cords, with one participant questioning the maximum effective length for these cables. While some suggest that longer cords can still function, they note that performance may degrade with increased length, particularly affecting internet speed and fax transmission. Overall, the consensus highlights the importance of adhering to recommended cord lengths for optimal device performance.

I had a broken fax machine, and we finally found the book, after a month of looking. It said not to use a longer than 6 ft cord... Why? We replaced our 20 ft. with a 5 ft., now it works... hmmm :confused:

Which "cord" are you referring to? If it's the RJ-11 (phonejack) one, the cord can only be so long, a maxiumum distance. I don't know the maxiumum distance of an RJ-11 cable, but I imagine it's rather low.

From experience I don't think it is anything as small as 5ft. I used to have a cable going around the house (about 70ft long if not longer) so I could use the internet from my room and it did a pretty good job and it worked sending faxes through my fax modem too.

Although the internet connection speed you get is actually lower the longer the cable you use, it doesn't stop you completely from having a connection.
 
Sorry if 'Profile Badge' is not the correct term. I have an MS 365 subscription and I've noticed on my Word documents the small circle with my initials in it is sometimes different in colour document to document (it's the circle at the top right of the doc, that, when you hover over it it tells you you're signed in; if you click on it you get a bit more info). Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...
Thread 'ChatGPT Examples, Good and Bad'
I've been experimenting with ChatGPT. Some results are good, some very very bad. I think examples can help expose the properties of this AI. Maybe you can post some of your favorite examples and tell us what they reveal about the properties of this AI. (I had problems with copy/paste of text and formatting, so I'm posting my examples as screen shots. That is a promising start. :smile: But then I provided values V=1, R1=1, R2=2, R3=3 and asked for the value of I. At first, it said...
