Deep dives
ARM and x86 Laptop Comparison
Laptops powered by ARM processors promise better performance per watt, longer battery life, and possibly more affordable pricing compared to x86 laptops. With recent improvements in software availability, users are increasingly comfortable running web apps or Electron apps in browser tabs. Learning about and exploring the ARM ecosystem can offer users a new perspective on computing possibilities.
Consideration to Buy an ARM Laptop
When considering the switch to an ARM laptop over an x86 one, factors like battery life, performance per watt ratio, and potential cost advantages can be compelling. Additionally, the opportunity to delve into a different computing environment and the potential for increased power efficiency and silent operation can be appealing reasons to make the shift.
Challenges of Adopting ARM Laptops
While ARM laptops offer enticing benefits such as improved battery life and performance per watt, there are also challenges users may face when considering a switch. Concerns about software compatibility, application performance, and the need to adapt to a new ecosystem are factors that users might need to navigate before fully embracing ARM laptops.
Continued Evolution of ARM Laptops
The ongoing development and improvements in ARM laptops hint at an evolving landscape for computing devices. With advancements in software support and increasing performance capabilities, ARM laptops are poised to offer users a unique experience that combines efficiency, power, and portability.

- Announcing systemd v256 — In the weeks leading up to this release I have posted a series of serieses of posts to Mastodon about key new features in this release.
- systemd changes with v2⁸:
- systemd 256 Released With run0, systemd-vpick, importctl & Other New Features
- Lennart on systemd-vpick — Basically, you can now place multiple versions of the same resource in some dir of your choice, suffix that dir's name with .v/ and the you get some basic version management in place: delete or add new versions by just removing/adding new files, and the tools will find the newest item dropped in automatically.
- Introduction to Portable Services — “Portable services” do not provide a fully isolated environment to the payload, like containers mostly intend to. Instead, they are more like regular system services, can be controlled with the same tools, are exposed the same way in all infrastructure, and so on. The main difference is that they use a different root directory than the rest of the system.
- Trying out systemd's Portable Services — All in all, the core pieces are already in place for a very promising new technology that should make it easier for 3rd parties to provide Linux system-level software in a safe and convenient way, well done to the systemd team for a well executed concept. All it lacks is some polish around the tooling and integration.
- systemd sleep — Putting a PC to sleep is complicated business and there are different mechanisms available to achieve this on Linux.
- Lennart on SSH and AF_VSOCK — This automatic ssh-via-AF_VSOCK logic is particularly useful
- DDIs and systemd-nspawn — Or in other words: there's now unprivileged systemd-npsawn containers. Yay!
- Lennart on systemd-vmspawn
- Lennart on sd_notify
- Lennart on dlopen
- Lennart on run0 — There's a new tool in systemd, called run0. Or actually, it's not a new tool, it's actually the long existing tool systemd-run, but when invoked under the run0 name (via a symlink) it behaves a lot like a sudo clone. But with one key difference: it's not in fact SUID.
