interesting - how would you do a hard currency, that is independent from emittends and trusted third parties, that is easy to store & move and is open to almost everyone?
But banks, at the very least, are heavily regulated to prevent all sorts of fraud and shell games - and these regulations are absent in much of the crypto trading business.
So if I _have_ to deal with currencies, who would I rather be doing business with - the huckster who has the Law standing with a big club behind them to ensure their good behavior, or the huckster who is totally unfettered?

A prominent computer scientist who has spent 20 years publishing academic papers on cryptography, privacy, and cybersecurity has gone incommunicado, had his professor profile, email account, and phone number removed by his employer Indiana University, and had his homes raided by the FBI. No one knows why.
The American Association of University Professors is reminding Indiana University's provost that as a tenured professor, XiaoFeng Wang is entitled to due process. The university, meanwhile, is maintaining radio silence, which isn't a good look to prospective students considering attending.
Here's the latest on XiaoFeng Wang, the distinguished computer scientist who was summarily fired on Friday from his tenured position at Indiana University, where he had spent 20 years racking up accolades for his research in cryptography, privacy and cybersecurity. It comes from Alexander Tanford, president of the Bloomington chapter of the AAUP, the organization representing IU professors, and colleagues of Wang's.
In February, an anonymous person filed a complaint alleging research misconduct against Wang. "The charge seemed trivial -- that he had failed to properly disclose who was principal investigator on a grant application and had not fully listed all his co-authors on an article," Tanford told me.
On March 13 or 14, IU temporarily suspended Wang, banned him from his office and denied access to his computer, research and data while the investigation continued. This is permitted under IU's research misconduct policy. The reasons, though, aren't publicly known.

On March 28, Provost Rahul Shrivastav informed Wang he was being terminated immediately. Shrivastav provided no reason (he mentioned Wang taking a job at a university in Singapore, but this is permitted and not grounds for dismissal). What's more, policy ACA-52, approved by the IU Board of Trustees, prohibits summarily firing a tenured professor.
Also on March 28, homes that Wang owns in Bloomington and Carmel, Indiana, were raided by the FBI. The FBI says the raids were court approved, but so far no one has seen a warrant. The US Attorney's Office for the Southern District of Indiana will neither confirm nor deny an investigation.
Indiana University has steadfastly refused to provide any reason for the termination or its failure to follow its own policy. Students and fellow faculty remain in the dark. His PhD students are frantically scrambling to find new advisors. One such student learned of Wang's firing only a few weeks before his PhD defense.
I reached out to Wang's attorneys 24 hours ago, and still haven't heard back.
We really need answers here. IU is tarnishing its reputation for academic independence. The lack of transparency here, both by IU and the FBI, truly sucks.

@SpaceLifeForm I can't imagine how. If you have enough access to a machine to add Calculater to a custom keymap (it's not in any of the keymaps shipped with xkb) and bind it to do arbitrary evil thing (it won't have a default binding in any desktop or application because nobody has ever intentionally used it), surely you can just, like, add `do-evil-thing.sh` as an autorun entry instead?

"Multiple regions of Russia have been struck by an unidentified virus that causes patients to exhibit persistent high fever and severe coughing - including throwing up blood."

@SpaceLifeForm Several employers ago, had to take a class about appropriate behavior w/other employees. Actions were split into broad groups; the worst group was called "swimming with the sharks." I had done a shedload of the worst behaviors with a coworker, like loaning money, but there was never any problem, nor were we fucking, which I can't remember if they directly called out. But I really miss her companionship, & it always gave us a good laugh to talk about swimming with the sharks.
The image depicts a figure standing in a dimly lit environment, wearing a long, dark blue and black gown with silver accents. The gown features a high collar, shoulder armor, and a wide belt with a decorative buckle. The sleeves are long and fitted, with silver cuffs. The figure's hair is dark and styled back, with a headpiece that includes a circular design. The background is a gradient of dark gray, with small white specks resembling stars, enhancing the mystical atmosphere. The figure's posture is upright, and they are looking directly at the viewer.

A post about where we are, and where we're going, in terms of #Reticulum performance and scalability, and some new experimental features.
Experimental Performance Features In the latest commits to master (version 0.9.3) of RNS, there's a few interesting (and pretty experimental) features that I think some people might want to play around with already, even though it hasn't been released yet.
First of all, a long-standing TODO has been implemented in AutoInterface, which will now sub-interface each discovered Ethernet/WiFi peer for much better performance and path discovery. AutoInterface now also supports dynamic link MTU discovery. These updates improve performance significantly.
Most "experimentally", and perhaps most interestingly, RNS now includes an optional shim for on-demand transpilation of the entire RNS implementation to C, and then compiling that to machine-local object code at run-time. If requested, this happens dynamically at daemon initialisation via Cython (and only once, of course, if no locally compiled version exists already).
The on-demand compilation step, by itself, provides an instant performance increase of around 2x in the Reticulum transport core, cutting per-packet processing time approximately in half, due to the much decreased need for context switches between the Python VM and C-based backend. Notably, this is without any of the many potential optimisations added yet, such as static typing of variables in the transport core, object property slotting, logic vectorisation and so on.
These optimisations, together with link MTU discovery now pushes the Reticulum transport core packet processing above 1.4 gigabits per second on my (relatively modest) test hardware, while still running on a single CPU core.
Faster Snake, Faster I've never really expanded much on how I envision the path to truly massive scalability for Reticulum before, and understandably most of the community has been focusing efforts in this regard on the tried-and-true approach of developing parallel implementations of Reticulum in compiled languages such as C, Rust or Go. That approach is something I very much support and value, and even a necessary one for wider availability and adoption, so please keep up the good work! But, it is not the area I will be focusing my own efforts on, and there's some interesting, but non-obvious reasons for that, so it's probably time to expand a bit on that.
One of the most critical components in the continued evolution of Reticulum right now, is keeping the reference implementation readable, understandable, accessible and auditable. Without those qualities present, creating alternative implementations - and systems on top of Reticulum - are just too tall an order to expect anyone to care about. At the same time, Reticulum targets very demanding requirements, both in terms of security, privacy and performance (both in the context of very fast links and very slow links). Actually resolving those requirements into a real, functional system is bizarrely complex, to say the least, and honestly I do occasionally wonder how I even got this far.
From the outside, it's understandably difficult to appreciate just how much design, testing, re-evaluation, validation and implementation work it has taken to get to the point we're at now. It's taken me ten years, and let's just say that it truly has been a complex journey. For solving tasks like this, a high-level language like Python is an absolutely excellent tool, and had I started out in C (even though that is my personal "favourite language"), I don't think I'd have succeeded.
Scaling, Massively Before discussing any further, I should clarify what massive scalability actually entails in regards to Reticulum. The current implementation is capable of handling throughputs in excess of 1 Gbps, which is definitely "good enough" for the foreseeable future. But down the line, and in the relatively near future, I think we need to start moving the target to transport capabilities of 100+ Gbps and network depths of millions (or even billions) of active endpoints.
There's a common misconception that Python is "slow", whatever is meant by that. From a more nuanced perspective, that assumption is incorrect. What can cause significant performance penalties in Python are the context switches between the Python byte-code VM and native machine code. But as I've already hinted at, those can be eliminated almost entirely by using the Python source code as a blueprint for deterministically generating machine-code, that run at native speeds. I'd estimate that simply implementing static typing, property slotting and locking the memory structures for various lookup tables will provide a further 30-50x increase in performance.
With the recent release of Python 3.13, we're also finally starting to be see the end of the notorious Global Interpreter Lock, allowing us true multi-core concurrency, and this along with the new Python JIT will speed up things even further.
But going beyond that, we're going to start needing to get a little creative. It's well-known that the TCP/IP stack is fast, but one of the primary reasons that this holds true in practical reality is a little less well-known.
On commercially available IP routers, be that consumer products or ISP-scale hardware, almost all of the packet processing doesn't actually occur on the CPU, but is hardware accelerated on custom ASICs, embedded in the router chipset. If you've ever tried bonding IP interfaces or inserting software based VPNs in your routing path on systems that provide no hardware acceleration for those operations, you will have seen your previous line-rates drop to significantly less impressive numbers.
There's not any real possibility of hardware vendors starting to design, fab and ship Reticulum-specific acceleration ASICs any time soon, so we can't rely on that approach. What we can rely on instead, is another type of general-purpose parallelisation solution, that has seen massive improvements in the recent years, and which is now more or less ubiquitous in all compute devices, the GPU. Even mobile chipsets and embedded SBCs include capable GPUs with quite ample memory and shader core counts.
By leveraging existing, general-purpose acceleration frameworks (such as OpenCL or Vulkan Compute), a truly general-purpose Reticulum packet-processing accelerator can be designed and deployed on more or less any existing system, essentially for free - at least in the sense that no new hardware has to be invented.
If active path tables and other transport-essential data structures are shipped off to GPU memory, and the internal states of the Reticulum transport core is made completely vectorisable, packet processing can truly be massively parallelised. The transport logic was already designed with such vectorisation in mind, but of course it will take some work to get there.
The beauty of this approach is that it will still work on any type of CPU as well, even if no acceleration hardware is present on the system. This allows for a single implementation that will dynamically adapt to whatever resources are available on the system, from a single-core SBC, to an accelerated core transport node capable of handling tens of millions of packets per second.
While all of this is immensely interesting, and something I'd love to sink myself into right now, realistically it's still something a ways off into the future, since there's plenty of other important work to do first. Still, I thought it would be good to share some of thoughts that form the basis of the current optimisation work, and where it is ultimately going.

Cool build! Thanks for sharing! Do you have it set up in transport/roaming mode as well, or is it uplinking to other RNode APs in the area? I have a similar setup in my own car, although not as neatly build ;)
@mark Thanks. Currently in transport mode. Not yet set to roaming because for now it is in only a few certain fixed locations in town. Acts as a testing station for now: allows others to see if they get an announce from it & for me to see if any messages received. I can test when walking/cycling if I can reach car from my mobile rnode. I reached it through Munich town from about 1 km. It is a 90% "unmonitored" rnode. I locate the car using a Meshtastic T-beam node with GPS in car & mobile T1000E
I’ve been meaning to get a Pixelblaze Nano, and separately bought a strand of small beads with (presumably) WS2812B in them to test a theory. If your board replaces the string’s USB-A controller and those holes provide strain relief, that’d save me the effort of figuring out the same. 😀
@vk2tty Oh cool! So the Pixelblaze Pico (don’t think there’s a Nano yet! 😆) itself would replace the USB-A controller, and one of the boards I’m making will either solder or connect to the Pico and break out its 4 pads into a USB-C connector and strand connector. The holes are a little more for sewing the board to something than strain-relieving the strand, I would have had to grow the board to do that and I was trying to keep it minimal. I’ll post more about the boards in a bit!

Minor technical error today. Realised we had some “fungus gnats” and I helped a sundew catch some.Taking a closer look, I realised it looked more like a wasp. No idea where they came from. Inconclusive iNat ID. Eventually realised the oak marble gall in a pot had a lot more holes in it than I remembered & put 2 & 2 together. More oak marble gall wasps had emerged & now lived in my oak-less house. Gall put outside & 10 mins of capture & release - balance returned. Leave the galls outside, kids.
