Here are some of the reasons the iPad Pro has failed to live up to expectations.
1. No 1080p or 4k video support on YouTube. Due to licensing issues Safari, nor any other browser can display even a 1080p video on YouTube. For a device that costs as much as this, this is unacceptable.
2. Uninstalling pre-installed apps. This may be a complaint towards the operating system more so than the device, but once again Apple suprises us all. Apps uninstall themselves! Magically. With no warning, Apple started uninstalling apps to make room for new content and never have to warn the user of disk space. Sounds like a great idea until you are offline somwhere and go to use an app you believed was on your device when in fact it was removed!
The easy way to unmount sshfs goes as follows
sudo umount -l directory
Use -l “lazy” which is required for unmounting sshfs
-l, --lazy detach the filesystem now, clean up things later
Speed up rsync over lan or wan with this simple addition to your command.
-e "ssh -T -c aes128-ctr -o Compression=no -x"
Her we use the new command in a safe (dry run) example
rsync -avn --progress -e "ssh -T -c aes128-ctr -o Compression=no -x" source/ user@x.x.x.x:/destination

It is easy to use Python with forever.js:
[raw]
forever start -c python python_script.py
[/raw]
To use it with virtualenv is a little bit more complicated, I did it using a bash script (call it python_virtualenv):
[raw]
#!/bin/bash
# Script to run a Python file using the local virtualenv
source bin/activate
bin/python $@
[/raw]
Now use that script with forever:
[raw]
forever start -c ./python_virtualenv python_script.py
[/raw]
Easy one liner to install nodejs and forever on Ubuntu 18.04
