This was an interesting problem to work on (back in 2017): A visualization of a path planner for 3D printing (FDM) a single layer/mesh structure of a multi-layer textile. Two setups of the same path strategy which optimized for longest continuous sub-paths and minimum rapids (distance without filament extrusion) between sub-paths. The planner supported six strategies in total, incl. optimizing for straight sub-paths and minimum amounts of "recent" crossings (to allow filament to co…
As OpenAI commits to spending $1.4T, creating a mesh of complicated deals, the startup does not disclose its auditor, and there is little information online (Louis Ashworth/Financial Times)

Oh hey, if you like mesh networking and hidden networks, you might want to keep an eye on https://reticulum.network/
It still has some issues, but it's getting off to a good start. It's kind of amazing how easy it is to embed it in other things for steganographic purposes. I definitely see room for improvement, but it's already exciting.
Nomadnet (built on top of it) is already really exciting. It feels very much like the 90's internet. Enjoy!
Verstehe ich das richtig, dass bei #ZigBee die Geräte ein Mesh-Netzwerk aufbauen und dadurch größere Distanzen überbrückt werden können als mit normalem Funk (z.B. WiFi) möglich wäre?
I used to use this "Mesh on demand" website to find articles relevant to a specific abstract - but it doesn't seem to work anymore, or maybe it's just me? Anyone else has been using it recently?

Mrs Losttourist just asked me "what's a Davy lamp?" and I was able to immediately explain it was a mining lamp consisting of a naked flame enclosed in a mesh structure so that it didn't explode, because I was taught that at school.
And now all I can think of is why the hell did they teach that to a London schoolkid in the 1980s?

My ZigBee mesh is now mesh due to IKEA bu^Wsmartplugs >> random Tuya from Ali. They do know how to route!
Random Ali sensors are more or less OK. #zigbee #homeassistant
India is rolling out millions of smart meters that are doing more than tracking energy use—they're fundamentally reshaping the grid.
As rooftop solar and EVs spread, decentralized RF mesh networks connect devices affordably while multiple vendors collaborate to keep the system resilient. The focus: financial sustainability and renewable energy ambitions.
It looks like #Bitchat might be gathering some traction in Gaza?
As a reminder, bitchat is a mesh network using your phone's bluetooth. So even without internet, you could have private messages sent from phone to phones.
Gaza having such a high population density and because Israel is known to have penetrated WhatsApp, this might be a good off-the-grid solution
I spent quite a few evening hours this past week modeling the production Morserino M32 Pocket case in FreeCAD. The original had basically been forked in a mesh editor, which made it hard to work from. Hans (of QRP Labs) kindly released his STLs, which made this work easier and the resulting objects better.
If you want a different color, or different plastic, or to make a modification to the design, you…
Hey @… I'm going to try to come to Mesh Night, tonight, but I don't think I can get there exactly for 7pm; is it weird if I show up a little later?

I really like Yggdrasil mesh VPN but I finally found a need to use it on my phone and its options for Android aren't really there. 🙁
I have set up WireGuard (as well) but now my naming scheme is all in question.
Register ANOTHER domain name for internal-but-behind-WireGuard?
Use a subdomain of the existing Yggdrasil domain?
Give up on Yggdrasil and switch everything to just WireGuard?
I guess I wait to see if I have any more use cases. The existing one is k…
Weekend #Plankton Factoid 🦠🦐
Many aquatic animals are described as "filter feeders" but this is not functionally correct since it would require water forced through a mesh. Instead, most zooplankton, including copepods, are suspension feeders. They create feeding current gyres using appendages, and use spiny modified ones (maxillae) to intercept individual algal particles and move …

Abstract: Light carrying transverse orbital angular momentum (T-OAM) in the form of spatiotemporal optical vortices (STOVs) is opening new degrees of freedom for structured light manipulation. Such spatiotemporal wavepackets hold significant potential for optical trapping, analog optical computing, studying photonic symmetry and topology, among others. Up to now, synthesizing of such vortices is limited in one dimension, either in temporal or spatial domain. In this work, we propose and experimentally demonstrate a two-dimensional flexible mesh of spatiotemporal optical vortices (M-STOV) with programmable intensity nulls, and analyze their diffraction patterns for detection. Furthermore, we extend the spectral range of M-STOV via second-harmonic generation while examining the transfer of OAM in this nonlinear process. This study establishes a foundational framework for designing higher dimensional spatiotemporal vortex fields and promises a high-capacity information carrier based on ST optical vortices.

What I really do like about the #Meshcore app is the ability to tell whether my messages are making it to the mesh. There are multiple ways to tell.
First is the display of heard repeats. That indicate that x number of repeaters have received and repeated the message.
The second is the explicit delivery confirmation in private message chats.
Thirds is the new way to di…
