• How To Use Letsencrypt SSL/TLS Encryption to Create Certificates without installing on the target machine

  • Samsung Galaxy Note Ubuntu Linux USB Connection Error


    This pops up when connecting the phone and it doesn't seem to charge. The phone keeps showing a status message every few seconds "Connected as a media device". It's ridiculous why this phone doesn't just default as a simple USB Mass storage device.

This happened when Iwas rsyncing a dying hard drive, a lot of people seem to report this as an error with rsync itself but I don't think rsync is the issue at all. I know the source hard drive was bad, it was having all kinds of timeout, seek, hardware ECC recovered and reset errors. The only time something else could be the problem is if the data is being corrupted in transit, perhaps through........
