My checklist to secure a VPS, enforced by an Ansible playbook.

* Disable SSH root login

* Disable password login and use only certificates

* Enable fail2ban

This have been worked for more than ten years and never been hacked.

I never understand the need for port knocking.

The area around Poggio a Caiano (west of Florence, between Campi Bisenzio and Signa, just for whom that know the area) was drained by the late Medici's and their successor, the Lorena's family.

After the first world war, they built a big area for blimps, with also a big hangar, but I am not sure if it happens during the Fascism or earlier.

I am living in Poggio a Caiano and I never expect it will be mentioned on HN. I know very well the history of Bianca Cappello and I am not surprised about the malaria. The area around Poggio a Caiano (Poggio means exactly "small hills") was a swamp and malaria was very common.

lormayna — Sat, 04 Jul 2026 14:13:24 +0000

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.

New comment by lormayna in "BYOMesh – New LoRa mesh radio offers 100x the bandwidth"

lormayna — Sun, 03 May 2026 19:45:56 +0000

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?
