 +10:19:42 From Barry Kort to Everyone:
 + QC3.0 stands for Quick Charge 3.0. It's a fast-charging technology developed by Qualcomm that allows for rapid charging of compatible devices. It works by intelligently adjusting the voltage and current levels during the charging process to optimize charging speed and efficiency.
 +10:20:14 From Barry Kort to Everyone:
 + Key features of QC3.0:
 + Faster charging: It can charge devices significantly faster than standard charging methods.
 + Intelligent charging: It adapts to the specific needs of the device being charged, ensuring optimal charging performance.
 + Improved efficiency: It reduces charging time while minimizing heat generation.
 + If your device supports QC3.0 and you use a compatible charger, you can expect faster charging times and a shorter wait between charges.
 +10:21:21 From Rich M to Everyone:
 + For what it's worth, USB-C PD has pretty much overtaken Qualcomm QC.
 +10:27:23 From Rich M to Everyone:
 + Maybe don't place a MagSafe phone on top of your old floppy disks :)

 +10:09:09 From Steve Isenberg to Everyone:
 + Secret questions work if answer is not related to the question
 +10:10:01 From Bob Primak to Everyone:
 + I think the point is, we don't want to be using the same communication channel for a login and the password reset process.
 +10:24:10 From Adam Broun to Everyone:
 + Replying to "Secret questions wor..."
 + ..and as long as you don’t reuse the answers
 +10:26:39 From Carl Lazarus to Everyone:
 + Replying to "Secret questions wor..."
 + A prime number has no factors.
 +10:37:28 From Barry Kort to Everyone:
 + For a while, LCC had an expired certificate, and the browser detected this and put up a warning message.
 +10:43:00 From Mitch Wolfe to Everyone:
 + Examples of bad certificates: https://badssl.com/
 +11:09:20 From Steve Isenberg to Everyone:
 + There is no mathematical difference between a “Public” key and a “Private” key.  Your system makes up two keys that work in a PKI system. Then it picks one as “Private” and the other as “Public” and shares the Public one.
 +11:20:23 From Dan Silber to Everyone:
 + I don't understand. If a password manager generates a different password for each application/server, how can compromising one password affect any other application/server?
 +11:25:03 From Steve Isenberg to Everyone:
 + In short, those password hint questions are also used as passwords (as they can bypass your secure password and reset it).  Best to use a random response to the password hint questions (or generate another secure password for the answers).

 +10:08:38 From Steve Isenberg to Everyone:
 + Why MKV and not other choices like MP4
 +10:11:47 From Bob Primak to Everyone:
 + MKV is known to support lossless video compression, which can result in larger file sizes but better video quality preservation.

 +10:17:22 From Adam Broun to Everyone:
 + Once you’ve recorded something can you edit it in here or would you use some other software?
 +10:40:34 From Barry Kort to Everyone:
 + LexMedia videos typically require a technical staff of three to six technicians on duty during a live session.
 +10:43:42 From Steve Isenberg to Everyone:
 + If anyone is interested in touring LexMedia let me know.
 +10:44:29 From Steve Isenberg to Everyone:
 + We can arrange a tour for a number of us to see the facility and discuss its technology.
