Private shared memory support for snaps

At first glance, the title of this article may sound like an oxymoron. However, what it highlights is the introduction of a rather useful feature that will enable a far more robust and elegant handling of the /dev/shm implementation inside the snap sandbox. This will make snap development easier, more secure, and reduce potential bugs

KDE snaps performance revving up

Speed, or rather, responsiveness is an essential part of the software usage experience. This applies to every technology and domain, snaps included. Indeed, when it comes to snaps, the equation is a bit more complicated and slightly less straightforward because snaps are packaged as compressed, standalone applications and wrapped in a num

Three ways to package your Electron apps as snaps

Software comes in many shapes and forms. One of the popular cross-platform, cross-architecture frameworks for building and distributing applications in Electron, which combines the Chromium rendering engine and the Node.js runtime. This makes Electron-based applications relatively easy to create. If you want to deploy Electron apps in Lin

How Snapcraft helps developers map out their application dependencies and efficiently build snaps

One of the core concepts of snaps is cross-distro compatibility. Developers can build their snaps once, and they should run well on more than 40 different Linux distros. But how does one take care of all the required runtime dependencies? By providing them inside the snap, as part of the bundle. In the snap ecosystem,

Let’s build a snap together – a complex snapcraft.yaml walkthrough

It has been a while since we talked about how to build snaps. In the past, we went through a number of detailed examples, focused on different programming languages and the use of various useful components that can be declared in snapcraft.yaml, like extensions, stage packages, layouts, and more. Today, we want to give you

The Future of Snapcraft

System hysteresis, when applied to software, can roughly be defined as an overall lag between desired implementation of code and actual implementation of said code. Ideally, this delay should be minimal, and programmers would be able to make instantaneous changes and improvements to their applications. In reality, things are more complex

Snapcrafters – One for all, all for one

In mid-2017, a small group of techies banded together and formed a team that would specialize in creating community-supported snaps of applications for which there was or would be no upstream support. This team called itself: Snapcrafters. Over time, it slowly, gradually grew, attracting more people and bringing yet more snaps under its u

Ubuntu Frame – A picture is worth a thousand snaps

The development of graphical applications intended for use on IoT devices isn’t trivial. The complexity goes beyond the usual challenges that exist in the classic desktop and server domains. One, the IoT world is much less mature. Two, developers need to take into consideration various edge cases that do not apply to hands-on devices like

Craft Parts – Reusable code, Snapcraft style

Throughout the ages, humans have always used simpler tools and materials to create more complex ones. Wood and stone for smelting bronze and iron; iron to create steel; vacuum tubes to create logical gates; logical gates to create advanced arithmetic engines, and so on. Modern software is no different. With Snapcraft in particular, the sn

Snapcraft offline mode – Build snaps while saving data

As part of the snap creation cycle, the Snapcraft tool creates isolated build instances inside which all of the necessary work – download of sources, compilation, packaging, etc. – is done in a safe manner, without touching the host system. While there are many advantages to the use of the virtual machines (via Multipass) or

Snapcraft experimental login – new, secure Web-based authentication method

Some Snapcraft operations mandate that users identify themselves. For example, if you want to push your snap to the Snap Store, you need to login on the command line. The process relies on the internal login mechanism built into Snapcraft. A preview functionality for a new Web-based authentication flow is available as an experimental feat

How to make snaps faster

A great user experience is (or at least, should be) an integral part of any software that involves user interaction. On the desktop, this starts with the application launch, and continues through the session. The overall time to completion of tasks as well as interactive responsiveness are a core element in this journey. If you’re

Snap Performance Skunk Works – Ensuring speed and consistency for snaps

Snaps are used on desktop machines, servers and IoT devices. However, it’s the first group that draws the most attention and scrutiny. Due to the graphic nature of desktop applications, users are often more attuned to potential problems and issues that may arise in the desktop space than with command-line tools or software running in

Snapcraft 6.0 is around the corner

A good sign of maturity and confidence in software is when said software utilizes its own components for future development and enablement. Snapcraft is a command-line utility that allows developers to package and distribute their applications as snaps. But Snapcraft itself is also distributed as a snap, and built in the same manner! Toda

Snap usage metrics now available on the command line

For years now, developers and publishers could view how well their snaps are performing in terms of usage and popularity through the Snap Store Web interface, using the metrics tab. This functionality allows people to examine the cause and effect of their work, like software updates, marketing campaigns, or other events. But it requires m

Snapcraft for Windows – Preview

Two weeks ago, Snapcraft reached its fifth milestone release, 5.0. This version brings in a number of significant changes, including the removal of the base (core) snap, which has been relegated to the 4.X channel track. For snap developers, especially those working in mixed environments, the availability of the first preview release of S
