Ktor-panel is a lightweight admin interface generation library for Ktor servers, and is currently in its last stages of development before official release to the public for consumption. Its selling points are the customisability and security. At the moment, the library supports ORMs and ODMs such as Exposed, Hibernate and the official Kotlin MongoDB driver.

I’d appreciate any feedback, GitHub stars or collaborations as there’s still a lot to build :)

Original question by @Shatur@lemmy.ml

I'm considering buying a robot vacuum cleaner, but I'm not a fan of the idea that it would scan my apartment and send data to the cloud.

I came across the Valetudo project, and it looks promising. It doesn’t replace the firmware - just replaces the cloud connection with local automation systems instead. Has anyone here used it? Or are you using something else for local control? I'd love to hear your experience 🙂

I needed another corded mouse and this time around I thought of @PKL@mastodon.social and @pronk@mastodon.social instead of Logitech's shareholders. These guys make open source mice among other open source hardware under the brand Ploopy. You can order one from them, assembled or as a kit, or you could print and build it entirely by yourself.

The mouse itself is pretty great. Coming from a long line of Logitech (MX518/G5/G500/G502), it's a bit larger than what I'm used to but I think I'm getting accustomed to it.

Here's another shot of it:

im working on a webapp and im being creative on the approach. it might be considered over-complicated (because it is), but im just trying something out. its entirely possible this approach wont work long term. i see it as there is one-way-to-find-out. i dont reccomend this approach. just sharing what im trying/investigating.

how it will be architected: https://positive-intentions.com/blog/decentralised-architecture

some benefits of the approach: https://positive-intentions.com/blog/statics-as-a-chat-app-infrastructure

i find that module federation and microfronends to generally be discouraged when i see posts, but it i think it works for me in my approach. im optimisic about the approach and the benefits and so i wanted to share details.

when i serve the federated modules, i can also host the storybook statics so i think this could be a good way to document the modules in isolation.

cryptography modules - https://cryptography.positive-intentions.com/?path=%2Fdocs%2Fcryptography-introduction--docs

p2p framework - https://p2p.positive-intentions.com/?path=%2Fdocs%2Fe2e-tests-connectionstatus--docs

this way, i can create microfrontends that consume these modules. i can then share the functionality between apps. the following apps are using a different codebase from each other (there is a distinction between these apps in open and close source). sharing those dependencies could help make it easier to roll out updates to core mechanics.

p2p chat - https://chat.positive-intentions.com/

p2p file transfer - https://file.positive-intentions.com/

the functionality also works when i create an android build with Tauri. this could also lead to it being easier to create new apps that could use the modules created.

im sure there will be some distinct test/maintainance overhead, but depending on how its architected i think it could work and make it easier to improve on the current implementation.

everything about the project is far from finished. it could be see as this is a complicated way to do what npm does, but i think this approach allows for a greater flexibility by being able to separating open and close source code for the web. (of course as javascript, it will always be "source code available". especially in the age of AI, im sure its possible to reverse-engineer it like never before.)

But admit this boost is only seen in 'an obscure filter'.

I think bitmask VPN broke my VPN setting somehow. I cannot connect to internet in my secondary profile but no problem in other profile

• can not connect to anything in this profile
• bitmask initial config is unsuccessful
• there is a notification "Disconnected from always-on VPN" even though I have I removed all VPN from my settings.
• clicking on "Disconnected from always-on VPN" notification gives "Can't connect to always-on VPN / [Legacy VPN] is set up to stay connected all the time. but it can't connect at the moment, you won't have a connection until the VPN can reconnect, change VPN settings"
• nothing to change in "VPN settings" as i have deleted all the VPN
• I have tried reset wifi and bluetooth in owner profile but still no connection in secondary profile

thanks a lot for any help

The guys at Flow Battery Research Collective have been designing a Redox Flow Battery development kit that you can build yourself using a 3d printer and a few tools. It's a desktop size flow battery that you can use to either do your own research, e.g. on different electrolytes or just to replicate their experimental findings.

Redox Flow Batteries have the potential to become grid scale or home electric energy storage solutions that are way better for the environment than current lithium based batteries. They can often scale power and capacity independently and allow for repairs.

The FBRC project wants to spread the knowledge on RFBs and help kickstart a global community that develops sustainable energy storage technology in an ope source fashion.

Beware that the project is still in its infancy and sourcing the materials can be a bit of a challenge. Be sure to ask around in the forums for help!

I made this tool some time ago to respond quicker to reports which didn't federate to the instance of my main account (lemmy.world). Previously I would have to check from multiple instances daily, and now I get a notification on my phone when a report is made within a couple of minutes. I cleaned it up a little and added some documentation in case anyone else is dealing with this issue or needs something like this.

UnifiedMap roadmap & "old" maps deprecation notice

c:geo has an all-new map implementation called "UnifiedMap" since some time, which will ultimately replace the old implementations of Google Maps and Mapsforge (OpenStreetMap). This is a deprecation notice to inform you about the further roadmap.

UnifiedMap got published about a year ago. It still supports Google Maps and OpenStreetMap (online + offline), but in a completely reworked technical way, and with a lot of exciting new features that the "old" maps do not support, some of which are

• Map rotation for OpenStreetMap based maps (online + offline)
• Cluster popup for Google Maps
• Hide map sources you don't need
• Elevation chart for routes and tracks
• Switch between lists directly from map
• "Driving mode" for OpenStreetMap based maps

UnfiedMap has proven to be stable since quite some time, thus we will remove the old map implementations to reduce the efforts for maintaining c:geo.

Roadmap:

• "Old" maps are in deprecation mode now - we won't fix bugs for it anymore.
• UnifiedMap will be made default for all users in fall of 2025.
• "Old" map implementations will be removed in spring 2026.

Until then, you can switch between the different implementations in settings => map sources.

Best Router device for openwrt 2025

I am completely new to OpenWRT/Pi-hole and need a recommendation for a device that could run OpenWRT/Pi-hole on it to replace my current router. I'm not even sure if I used the correct wording in this sentence, lol.

I have checked:

• https://forums.whirlpool.net.au/archive/9xkk75w3
• https://openwrt.org/supported_devices
• https://reddit.com/r/openwrt/comments/1e3t29i/whats_your_favourite_openwrt_router_which_would/
• https://openwrt.org/docs/techref/hardware/list
• https://openwrt.org/toh/recommended_routers

I need recommendations for devices to get some hands-on experience. And please explain the advantages of the devices you recommend a bit. There are indeed a lot of options listed on the internet, but not enough reasons are provided.

• I need Pi-hole because I want local DNS, but I guess OpenWRT could do the job as well.
• My current router does not support changing the DNS server.
• I need a simple substitute.
• I need good performance because it might need to connect to about 15 devices (though I have no idea what good performance means in terms of a router).
• So I guess a device with at least 256MB of RAM is needed.
• No limitation on price as long as it is not excessively expensive.

• Users should consider multi-core, ARM-based (or x86_64/AMD64) devices for mid-range and higher applications. (From https://openwrt.org/toh/recommended/_routers)

Thanks for your help in advance!
