Throughout our Free and Open Source Software tutorials, we need to specify passwords for things. Creating random passwords is surprisingly hard, but we've found a method that's very serviceable and makes it easy to do as we all should: ensure every separate identity or service has a strong password that is unique to that identity and application (i.e. never use the same password in more than one place). We also strongly encourage you all to track your passwords using a password manager!
Just about any and every server needs to be able to send email - whether it's end-user-email, like password recovery services for a website to emails to system administrators reporting on the status of system backups and errors. The problem is that it's non trivial (understatement) to set up a mail server properly.
SkFor any website that requires anyone (users or even just a few admins) to transfer secrets to and from it, you want to ensure the data is end-to-end encrypted. Today various browsers (like Firefox) give warnings when you're sending secret data (like passwords) "in the clear", namely unencrypted.
For relatively lightweight applications that are either in development, or single user, or have limited requirements for concurrency and massive data sets, SQLite is a superb, full-function, but compact, almost ubiquitous database (it's used on every mobile device, for example).
I have previously provided an in-depth explanation about NextCloud with Collabora Office Online and how we've installed it on Ubuntu 16.04. This is an update both of the process, and of the technology.
With the recent release of Rocket.Chat 1.0.x (after a couple years undergoing development at a fairly blistering pace), it's time for many of us to upgrade!
Previously, I showed how to install Rocket.Chat via Docker Compose but that was a much earlier version of Rocket.Chat and version 3.4 of MongoDB, which is now quite old (by FOSS standards at least). And it turns out upgrading everything has a few gotchas, so here's how I managed to do it.
Dropbox is the best known of the end-user "cloud storage" services for documents, backups, and synchronising data among multiple devices, although now Google's Drive and Microsoft's OneDrive are functionally similar and are being heavily promoted and tied into all sorts of services.
