       nuintari's rules of networking 0x2c:Never scrounge a cable out of the trash.  It's in there for a reason.1st Corollary:Always cut any cable you're throwing in the trash to prevent breaches of the aforementioned rule.2nd Corollary:If you replace ends on a trashed cable without also running it through a tester, you deserve any and all of the pain coming to you.3rd Corollary:The end connectors are not the only place cables break.

       Inherited a big bin of various cables. Found this monstrosity inside.This here is a fine example of exactly the kind of cable that belongs in the trash.You might be able to replace the broken ends and make a working cable, but it isn't worth the five minutes of time and 60 cents worth of ends to find out if the cable has been bent beyond repair.

       @nuintari My last Big Company job, I had to rewire the datacenter from "a collection of 100-foot cat5" to "patch panels." My predecessor had considered pulling unused cables out from under the floor to be high-risk, so there were 15 years of abandoned cables below.Step 1 was remove abandoned cable. I assumed these cables were abandoned for a reason.I dropped a box of dead cable by the trash and one of the engineers passing by said "are you throwing those out?""Yep. They're untrustworthy.""Can I have them?"<blink> "They're untrustworthy.""I can use them."I shrugged.From that moment on, the hundred or so automotive engineers in that office haunted the trash looking for free cables. I wound up labeling each box BAD CABLE. They took them anyway.Months later, in casual conversation, I asked one how his free cables had worked out. He shook his head and admitted he'd thrown it out.You tell them, and you TELL THEM, but noooo...

       @mwl @nuintari I've worked with tech (loads of it considered broken) for more than a decade now. My rules are:-) Don't use anything before testing it-) Don't throw out anything before testing it.But more generally:It's not working or broken before you confirmed it to be working or broken.And that's in isolation and out of the system. Had too many corroded or just simply disconnected connectors ....

       @cid_terron @nuintari A cable tester is essential. Someone sneezed? Test. New cable still in package? Test. Perfectly good cable that's never caused problems? Double test.

       @mwl @nuintari if you wire, cable manage and ship a system with a broken cable. That's sometimes weeks of trouble + reputation loss + angry sales guy + ....If you have a QM department and they do a system test. It is at least a day of work until you found out & ensure it was only the cable and fix it... For me, doing a quick check of the cable is a few seconds.But I'm an embedded systems guy, working in a safety critical environment.
