criu VS Electron

Checkpoint/Restore I feel is a bigger concept than just saving state. At the zeroth level it's a system that can correctly stop and serialize a running process (as criu https://github.com/checkpoint-restore/criu has shown is a huge pain in the ass to still not be perfect) in a way that can initiated from within the process itself.

The 1st level more-work-but-easier way to do this is to build or use a heavily constrained VM/language you run from within your main application that doesn't allow for most of the hard problems to even exist.

I can't find any ready-made tools to do this that I wouldn't consider an endeavor.

That being said the Checkpoint Restore In Userspace project has been around for a number of years and is the closest thing to what you are talking about: taking a linux process on one machine and moving it to another. It is messy but can be done in some cases. There are folks looking at how to integrate CRIU with k8s but it’s all research at this point.

I would love to make more use of CRIU. E.g. I considered to use CRIU for my Python preloaded logic (https://github.com/albertz/python-preloaded). Unfortunately, at that point in time, CRIU must be used with root access, which was not an option. However, I see that the PR was merged now, so maybe it works now? (https://github.com/checkpoint-restore/criu/pull/1930)

There is also DMTCP (https://github.com/dmtcp/dmtcp/) but this might have other problems for my use case.

My solution was to use a fork server instead, which works almost equally well. There are not really much downsides with this approach. And this is actually quite simple, and also quite cross-platform (except Windows).

CRIU currently needs root access for dump/restore. However, there is ongoing work to support a non-root option in https://github.com/checkpoint-restore/criu/pull/1930.

There have been multiple checkpointing attempts over the years. Criu is the only one I know of that's still kicking. That's probably your best and only bet.

The team at Electron have been faithfully shipping new releases almost every single month. I think they had Christmas off 🤔. This popular framework has developers writing cross-platform desktop applications using JavaScript, HTML and CSS. The latest update depreciates some process events, and added new modules, APIs, methods, and more. Read into all the changes in the Electron release notes. This month, Electron also introduced a new formal RFC process.

VS Code has been crashing at launch in Wayland since more than eight months ago:

So we talked a lot about the Atomic Design Principle, but you could just use that in any system and start creating. You could have Angular components, React Components, and Vue Components. But if you notice these don't easily work Everwhere. So the solution is to use Web Components because the modern browser can already understand these, and any Front-End framework can then utilize these components. You can use Electron for desktop (Slack, VSCode), PWA for both Android and iOS, and across all browsers Can I Use.

I'm noticing a significant boost in performance, crisper text, and better power savings. The only shortcoming is that the window which Figma will run on will lose its shadow. This is due to a technical limitation with frameless windows on Linux.

For the longest time, building desktop apps was a daunting task to web developers. That is, until technologies like Electron made creating these apps more approachable to a wider audience. Today, we’ve got a wide array of native applications built with solutions like Electron, Tauri, Capacitor, and many more. While these are great solutions, sometimes configuration can be tricky and the applications we create can become somewhat bloated in terms of memory usage.

It does, see [0]. Fun fact: Signal desktop, which uses Electron under the hood, is running without sandbox on Linux [1][2].

Turns out, there is an issue with the electron window not returning focus correctly on mac - https://github.com/electron/electron/issues/5495. The trick to solving is to treat quick capture as a screensaver. When closing, you hide it by setting the opacity to 0 and sending hide: command to the first responder.
