Yaesu FT-450D ft8 setup

 My ft8 laptop died recently so I had to setup a replacement from scratch.

I did not remember my wsjtx settings so I spend quite a bit of time to figure them out.

What works for my rig is the following 

For future reference.

Working with hours minutes and seconds in HP Prime

 HP Prime has a button that can be used to express degrees minutes and seconds or, hours minutes and seconds it is the a b/c fraction button and it is a shifted operation.

Type the number of hours, press the key, then the number of minutes press the key and then the number of seconds and press the key.

This way we can perform calculations that are time based

Unmounting stuck nfs mounts

 

This usually happens when the nfs server is down, you cannot umount the nfs mount, because the system will say "not found or server not reachable"

$ sudo umount /opt/logs/production

umount.nfs: nfs.local:/var/lib/backup: not found / mounted or server not reachable

umount.nfs: nfs.local:/var/lib/backup: not found / mounted or server not reachable

To fix this, you need to force mount it with lazy flag:

$ sudo umount -f -l /opt/logs/production

where -f is to do force unmount, and -l is for lazy unmounting. From man:
"Lazy  unmount.  Detach  the  filesystem from the filesystem hierarchy now, and cleanup all references to the filesystem as soon as it is not busy anymore."

Fuzzy finder

 I learned recently about the fzf linux cli command. This is a text finder similar to grep but a lot more powerful. It can be used not only to find text but files as well in an interaftive mode.

It exists as a package for debian and its github page is: https://github.com/junegunn/fzf
