Super Mario Bros. Level 4-2 - Deep Dive

This is fascinating. I knew people did speed runs, but I cannot believe the depths to which they've gone.

We are also thrilled to present a whole new way to connect with amplifiers, allowing you to use a handheld mic and built-in speaker - just as if it were a mobile or base radio (but at a significantly lower cost)."


Prices range from $88 to $105 based on the model.

Compromised Passwords

Troy's updated his site, Pwned Passwords. Read the details here to see if you want to trust it with testing your password.

I couldn't easily find it, but I thought I had shared his other service: Have I Been Pwned? You provide your e-mail address and it will let you know if it is found in any of several data breach databases dumps. You can also get alerts if your e-mail address shows up in a future breach.







Home Network - Part 2

So that change didn't go as smoothly as I had hoped... turns out the latest firmware for the ASUS RT-AC3200 has a 2.4 GHz bug. It took me a long time to figure out that was the problem.

I noticed the issue on some of my IoT devices and my wife's hand-me-down laptop. I assumed it was a problem with the devices. Basically, I kept getting a bad password error. I ended up trying a lot of different things - laptop driver update, deleting all the network settings, resetting the IoT devices to their default config, changing the SSID, etc.

It wasn't until I realized I was having the problem on my laptop and my iPhone 8 that I started thinking the router was the issue. Originally I had those devices configured to use 5 GHz only, so they never experienced the problem. After a short search, I found this thread: 2.4GHz band issues with RT-AC3200 firmware 3.0.0.4.382_50010. Bingo! That was exactly my problem. I rolled back to an older firmware version and everything has been working like a champ.

On a happier note, I returned my Comcast cable modem, since I had purchased the NETGEAR CM500-1AZNAS. I walked in the retail store, they scanned the label on the modem, and printed a receipt. It took less than 30 seconds. Perfect!

For an upcoming post, I may list all the devices I have connected and note which ones were easy to migrate to the new SSID. (Spoiler Alert - the inexpensive Smart Plugs I bought have some horribly written instructions.)

Disc 2: Blazing Saddles
Disc 3: Young Frankenstein
Disc 4: Silent Movie
Disc 5: High Anxiety
Disc 6: History of the World - Part 1
Disc 7: To Be or Not to Be
Disc 8: Spaceballs
Disc 9: Robin Hood: Men in Tights
