fossil core dumped error – home directory must be writable

I got this fossil error during the latest server setup on Ubuntu. Earlier, it was just the question of adding fossil to the path.

But for some weird reason, I got this error this time –

home directory "" must be writeable
Aborted (core dumped)

After trying to search for the error, I finally got a clue at this fossil check-in, which shows the check for write access to the home directory to create a .fossil file.

Checking all accesses, everything seemed absolutely correct, so the only thing left to do was to create the file manually –

touch ~/.fossil

This solved the problem correctly.

ruby – update default bundler

Whenever I get this error, I have to again do a google search. So, this post is for me not to do that again!

Could not find 'bundler' (2.1.4) required by your .Gemfile.lock.
To update to the latest version installed on your system,
run `bundle update --bundler`.
To install the missing version, run `gem install bundler:2.1.4`

Unfortunately, the suggestions don’t quite work.

The correct way to fix this is to run these three commands:

gem install --default bundler
gem update --system
bundler update --bundler

Use Wake-On-LAN to wake up another computer when your PC resumes

Starting up another computer on a network itself is such a fascinating idea! For me, it literally feels like magic!

There are so many things involved. The computer which needs to be started (or woken up) has to have the capability, both at the hardware and the software level.

Also the computer doing the waking needs to send a magic packet!

When I initially heard this, I honestly thought this was a joke of some kind. A magic packet? Really?
