  • I just tried it, sadly it doesn’t have a camera sensor option to detect and translate flashing Morse Code from another source, but it does have a Morse to Text translator that you can manually enter the incoming dots and dashes and it’ll translate back to text.

    The send feature converts plain text to the appropriate dots and dashes, with options to flash the screen, the flashlight, beep over the speaker and also vibrate. Dunno why they chose red as the screen flashing color with no option to change color though…

    For it to be version 1.0.1, its actually alright, it does work, although slightly clunky (but simple) UI right now. Everything, even the custom text you enter, has to be accessed in the Settings menu.

    Its worth a try, I’ll be keeping it on my devices to go alongside the Survival Manual app (different developer), and hope to see some improvements and new features down the road…





  • I hear ya there, but…

    I be getting really confused when one config boots from /dev/sda, but when I have my backup drive attached (not the boot device), it boots from /dev/sdb

    Hell I dunno, I probably confused the hell out of my laptop plus myself with my cutout mod reconfiguration, but it’s happy to boot from almost anything now.

    Almost…

    Hey, at least I know how to restore to my previous state from backup via dd 👍




  • My 128GB is meant as an integrated NVME drive.

    Meant to be. I literally cut a service panel hole under the laptop to remove or reinstall it whenever I feel like, or maybe eventually upgrade it.

    I’ve been booting off of other devices, like my 8GB USB flash, 100GB USB HDD, and even Live Boot USB DVD drive. It’s actually been very convenient, as I can boot off of whatever the hell I want from USB.

    My backup is on a 4TB, so really no worries to me, I can more or less freely experiment around with whatever OS I want, and if it doesn’t work right, I can just dd my backup over whatever again, and it just works.

    But why doesn’t the dd 100GB>128GB work as I’d expect?

    Obviously that’s not the exact dd command I used, for privacy reasons.

    🤷


  • The goal was to migrate the 100GB to the 128GB, hopefully expand it, and format the 100GB for future temporary/experimental use.

    I never planned on having both drives actively running at the same time, so I don’t think there should have been any UUID issues, nor did I run across any errors suggesting such an issue.

    But even without expanding the partition, the dd command should have 1:1 copied the 100GB, with space to spare, and be bootable, right? Or so I thought…

    I had no problem dd restoring the original 128GB contents though, so at least I didn’t bork everything. Also the 100GB external USB is still fine. 👍

    🤷


  • You sound like you know some things that perhaps I don’t know.

    Slightly different question…

    I have a 128GB SSD with Linux Mint MATE 20.3, and I did a full and successful dd backup to my 4TB backup drive.

    I have a 100GB external USB hard drive as a test medium for Mint MATE 22.1. I am happy with my test setup, and tried to dd that over to the 128GB SSD. But it wouldn’t boot.

    I restored the original 128GB SSD image and all is good right now, but why the hell didn’t the 100GB>128GB even boot?

    Edit: Secure Boot has been disabled all along, screw that headache.

    Tapes can have long term issues in storage, as the tape reel winds will eventually start to bleed over magnetic signals from one wind to the next.

    In analog world, they call it tape hiss. In digital world, with good error correction, it can last a long time, but is still ultimately prone to data corruption, eventually…

    I recommend a video surveillance rated multi terabyte hard drive, they’re designed to run 24/7. I have two 4TB Seagate Skyhawks.



  • Well shit, I figured out what the real issue was.

    I’m on a laptop with only 3 USB ports, and I’m running a physical laptop hard drive on an adapter on one USB port, and a laptop CD/DVD drive on another adapter on another port.

    Obviously that’s probably pushing the power limits of the USB power, but it’s worked before, so I didn’t see why it wasn’t quite working right now.

    But this time I was trying a different DVD drive, an HP TS-T633P slot loader drive. Apparently that drive is extra power hungry compared to a conventional laptop drive, so I dug out my old tray loader drive.

    Apparently the slot loader drive was competing with the hard drive for power, and they were apparently taking turns robbing power from each other. The system is perfectly happy with the tray loader drive though, no reconfiguration necessary!

    🤦‍♂️😂🤣👍
