kb Handle files with very long names in Windows Yesterday I stumbled upon a problem that is quite unusual: a user has been able to download a file with a very long name, and since Windows can only handle path of 259 characters for files it was impossible to delete or rename the file. I tried in cmd to
kb Download a certificate from a web page via CLI I wanted to get the certificate from a Kubernetes API server, so I thought to download it from the https page, but then I had to use in a server without Desktop Environment and I didn't want to bother copying it with scp, so I searched a way
