Show HN: I made an open source desktop magnifier for demo and presentations I wanted a cool magnifier for my presentations, but couldn't find one (the default windows one was not really usable for my case) So I built one using Vue and Tauri (weird stack for such a tool, huh?). It was a pretty fun little project, hope you guys can have some use. Here's how it works: - When you press the shortcut, it takes a screenshot and store it in a temp folder - It then displays an HTML window and passes the screenshot URL to it - The HTML window has no "decorations" (top bar) and only contains an empty div - This div uses the screenshot as a background and updates the background position based on the cursor location - The window location is also updated according to the cursor location using a requestAnimationFrame (so that it does not get triggered too often) - The wheel event impacts the size of the window, as well as a transform:scale on the background. https://ift.tt/ahRqymp May 6, 2023 at 04:44PM
Show HN: Launch VM workloads securely and instantaneously, without VMs Hello HN! We've been working on a new hypervisor https://kwarantine.xyz that can run strongly isolated containers. This is still a WIP, but we wanted to give the community an idea about our approach, its benefits, and various use cases it unlocks. Today, VMs are used to host containers, and make up for the lack of strong security as well as kernel isolation in containers. This work adds this missing security piece in containers. We plan on launching a free private beta soon. Meanwhile, we'd deeply appreciate any feedback, and happy to answer any questions here or on our slack channel. Thanks! April 29, 2021 at 07:50AM
