If you have Panasonic Toughbook laptop with no LTE/4G cellular modem and after you attach internal modem but it is still not visible in BIOS Setup nor in the Operating System, go to the Main / Optional Kit Configuration, use toughkit password, then set Wireless WAN ID = 15 (in case you use original Sierra Wireless EC7305 device). WWAN card should be now available both in BIOS Setup and Operating System USB port. Enjoy! πŸ™‚

If you encounter turtle slow Windows 10 boot time on a decent machine it may be caused by AMD/Radeon driver’s ULPS. Try the following:
1. Launch REGEDIT.
2. Search for “enableulps” key.
3. Set its value from 1 to 0.
4. Reboot and see if that helped πŸ™‚

If you need to perform a data recovery from an external ZFS [zfs] volume you may find those hinds helpful:

  1. Attach encrypted partition where ZFS pool resides with:
    geli attach /dev/your_device_partition
  2. Import ZFS pool at given mountpoint (/mnt/zfs):
    zpool import -af -R /mnt/zfs
  3. Modify mount point location for a given dataset that may have mountpoint set to none what marks it as no mount (note this mountpoint will append to parent mount point location):
    zfs set mountpoint=ROOT zroot/ROOT/default
  4. Mount and mount all pool datasets:
    zfs mount -a
    zfs umount -a
  5. Mount/umount given dataset:
    zfs mount zroot/ROOT/default
  6. You can verify if your ZFS pool is active with:
    zpool status
  7. You can see what ZFS datasets are available with mount points with:
    zfs list

If you encounter lots of CAM/CRC errors when using encrypted ZFS on some SSD drives on FreeBSD, that is caused by TRIM. You need to disable it in boot loader prompt or add below line to /boot/loader.conf:

vfs.zfs.trim.enabled=0

If you encounter a problem with running Python [python] scripts on a “bare” Blender Player [blender], make sure that both PYTHONHOME and PYTHONPATH are set correctly to match your needs. You can also use native Blender python with a simple shell script:

#!/bin/sh
export PYTHONHOME="/path/to/blender/python/"
export PYTHONPATH=$PYTHONHOME"/bin"
/path/to/your/blenderplayer $@

If you want to move a business from Microsoft Office365 to Google Suite, there is a nice migration utility in Google Suite Admin Console that helps you transfer all accounts data from Exchange Web Server or IMAP.

In case you encounter an error here goes a list of error codes and troubleshooting guide [1].

I did a full migration by granting my temporary user Global Administrator right by current Admin user, then in Exchange Admin Console I had to grant myself an ApplicationImpersonation Admin Role (to access other accounts for migration). After the migration was complete I have rolled back my permissions to a minimum level.
