I have a Vespa PX 125 from 1984. It's a very robust motorbike, very less maintenance and really funny to drive with the gearshifter. The only problem is about brakes: there are basically useless and you should be really careful on using them, especially if you are driving on wet road. Bad brakes and small wheels is a terrible combination.

Probably the main regret to WFH is not using my Vespa anymore as I did when I was going everyday in the office.

Fiorentina, in Serie A. After 11 matches we have only 4 points and we won the first match only in December: in the past nobody got saved with a so bad performances in the first matches.

My favourite football team was really at risk of relegation, then I created for me and my friends an MCMC bayesian simulator to estimate the relegation match by match. It was an opportunity to get used in real life to some concepts (MCMC, Metropolis-Hastings, etc) that I always struggled to understand. And my team got saved from relegation with an amounts of points very close to the number of points that my model forecasted

I also wrote an honeypot that emulate an Ollama instance: beside the attackers, it's funny how many people are looking for free inference. Somebody from Brazil try to use my honeypot to write to chapters of a book about traditional magic rituals. My next step is to extract the data collected by this tool to extract IoC and malicious prompts and share them with the community.

In the same scope I wrote also an Ollama scanner: it fetch from Shodan the open Ollama instances, verify that they are reachable and check if they are real sending a dummy query.

Agree! And we need also to consider that a mesh protocol for Meshtatic/Meshcore should support mobility and have to run in a low power devices

I am an happy user of Meshstastic since more than one year (I have two active nodes and a third one is in the making). I am living in hilly countryside and the difficult that I have experienced is about reaching other nodes: with the standard antenna, I can barely connect with nodes in a 500 meters range, with a better antenna (coaxial collinear is the best IMHO) I can reach more than 10km.

I don't think the Meshstatic approach of "flooding" the network with all the messages can be scalable in the long run, they need to implement some sort of routing protocols (like BATMAN), but they are heavy and complex to implement

Italian here: as the first reading, I thought it was an usual decision against progress and technology. But reading the article it seems a good sense rule: Lombardy was one of the most industrialized zones of Europe and now is migrating to a post industrial model. This law should force reusing the old and unused industrial spaces instead that wasting space in agricultural areas.

My master thesis was about an application of SSS to mesh networks: even if one of the node of the mesh was captured by an attacker and the secret retrieved from the node, it was impossible to crack the whole encryption.

Only on the paper, the real power is around 3/3.5W

When I was a poor student, Zaurus was probably my biggest tech gadget dream. Unfortunately it was rare and expensive and I never had the opportunity to play with it.

6 miles seems a very optimistic estimation: 2.4Ghz propagation is very reduced by obstacles like buildings or trees and at that frequency the atmospheric water (fog, rain, humidity) have a big impact on propagation. And you need also to consider that 2.4Ghz is a very polluted band, then the noise floor is significatevly higher than in the 865/915 Mhz. Moreover at 2.4Ghz the Fresnel window is smaller and the risk of multipath fading is higher.

Propagation (FSPL) is a lot better at 868/915 Mhz than 2.4Ghz. What is the advantage to have a "super BLE", that can propagate for few hundred meters?

Also for a student: I was at university 20 years ago and there was no possibility to "hack" RF devices. Right now, with less than 200€ (a NanoVNA and a good SDR), you can do almost everything.

There is a waste area in the Italian society that is very prone to the conspiracy theory. Some famous journalists and some TV shows are very good in spreading this news. In the past, a party (M5S, now pivoting to a left wing, populistic, pro Putin movement) took 34% at the election, just taking advantage of those crazy ideas.

Not a medical professional, but inflammation is something different from cancer that they mentioned in their website. And we need to understand also the trial scenario: in the one about 5G they expose rats for more than 20 hours to a radio power more than 10 the law limits.

In Italy we have an "indipendent research lab" that become really famous for a study that demonstrates that aspartame may cause cancer. The same institute published few years later a study about 5G emissions that may cause cancer.

This is a very good point to start: https://www.rtl-sdr.com/tag/passive-radar/

If you have more than one receiver, the main issue is time sincronisation between the receivers.

Using the two transmitters will complicate things a lot

I did my master thesis working with that in 2006. It was fun but challenging to work with a so primitive OS (no memory dynamic allocation, etc.) and so many bugs.

Close where I am living (Tuscany) there is a small industrial district focused on adesive paper production. I had sent this link to a friend of mine that is working as plant manager for one of those.

In Italy, in the past people starts paying tickets that they think unfair completely in coins. The government had to introduce a maximum amount that you can pay in coins to protect the employees that otherwise will spend day on counting cents.
