Ubuntu 17.04 Uses Swap File Instead of Partition

Traditionally, when you install Linux, one or more partitions are created for data, and another partition is created for the swap. This is generally more secure because programs can’t directly access the data that’s kept in the swap partition.

Starting with Ubuntu 17.04, fresh installs will use a swap file instead of a swap partition by default. While this technically might not be as secure as using a swap partition, swap files aren’t really a security concern, and it will also make a number of things easier.

Using a swap file will make partitioning much easier as no swap partition needs to be created, and it will also allow the swap to grow as necessary. Swap partitions are created with a fixed size and always remain at that size, while swap files can grow as needed.

Overall, I think this is a good path for Ubuntu to take. Often, keeping things simple is a better answer.

Thoughts and Concerns about the Ubuntu Mir Server

As much as I enjoy Linux and technology in general, I also do a lot with games and gaming. I have a gaming channel on YouTube and enjoy creating game videos. That means I need to be able to record game footage using as few system resources as possible. Certainly an external recording box is an option, but for a variety of reasons I prefer to use a software solution.

On Windows this is easy. Because I have an nVidia graphics card Shadowplay is often the best option for recording games. It’s quick and uses almost no resources.

On Linux my options are currently SimpleScreenRecorder and OBS Studio. Both recording solutions rely on the X Window system, the current graphical server used by most Linux distributions. However soon some Linux distributions will begin to ship with the Wayland server… in fact Fedora 25 already does… and Ubuntu, which is both the most popular Linux distribution and the one I primarily use… will ship with Mir, its own graphical server.

While nVidia has said they’ll write graphics drivers that work with Mir, there still aren’t any screen recording solutions for Mir. It all makes me wonder how long before screen recording solutions for Mir will be created, especially ones that work with games, and once they are, how many resources they’ll use and quick they’ll be.
