Question #29: Is there an easy way to test whether router port forwarding is working correctly?
Asked by Jesse (10.0.0.x) on July 30 2022, 8:44 PM

Response: Yes, set up the port so that it forwards to your computer LAN IP address. Run the program "netcat" with arguments "-l [PC port]" so it listens on that port. (Netcat can be downloaded on Windows using Cygwin). Then run another instance of netcat and connect to the Internet IP address: "nc [your WAN IP] [your WAN port]". If port forwarding is working, you can type text into the client and see it on server.

Question #27: Is there a way to keep the rear wheel nuts in the correct position even after jumping off a ramp or a curb? Landing is hard on the rear wheel which makes it move forward and loosens the chain tension.
Asked by Jesse (10.0.0.x) on July 25 2022, 9:38 PM

Response: Yes, you can install rear axle tensioners on the rear bolts.

Cheap type: https://www.aliexpress.com/item/2251832780835077.html
Better type: https://www.amazon.com/Origin8-Chain-Tension-Adjuster-Black/dp/B001GPJY1O/

Take off the rear nuts, install the tensioners between the threads and the nuts. Tighten the tensioner so that the chain has reasonable tension. Then screw the rear axle nuts back on. The tensions hold the wheel against the frame so it can't slide forward.

Question #25: What's the fastest way to join a bunch of mp3s together? For example, you're converting a PDF or TXT to an audiobook using many text-to-speech threads.
Asked by Jesse (10.0.0.x) on June 02 2022, 9:09 PM

Response: You can just append the binary files together then use a program such as mp3val (free program) to fix the mistakes. You won't be able to hear the difference. This method is much faster than joining mp3 files in a standard way.

Question #24: What is your take on privacy? Google Drive and OneDrive or your own little home server? I think with the possibilities to make a NextCloudPi with nearly zero experience, everyone should at least consider having all the power over their data.
Asked by Albi (79.221.236.x) on May 25 2022, 9:09 PM

Response: I use Google Drive for Google Docs. My little home server hosts a lot of different types of files: video DVR for ATSC, FiOS, security cameras, etc.

Question #23: How hard is it to get a license to transmit amateur radio? How much does it cost?
Asked by Jesse (10.0.0.x) on May 21 2022, 9:49 PM

Response: It takes about 1-2 weeks to study the questions. There are three difficulty levels that determine your rank as an amateur radio operator. The passing score is forgiving so you can get some wrong. It's $15. It allows you to transmit over the radio pretty far away depending on your equipment and antenna. You don't need a license to receive radio signals. You can receive using a device such as the HackRF software-defined radio.

Asked by Jesse (10.0.0.x) on May 21 2022, 9:47 PM
