I am trying to learn Rust. Not an easy task at all.

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.

As Italian, I really disagree. The only entities that pay all the taxes are employees because the taxes are collected directly from the salaries.

Big companies have the opportunity to make tax elusion (there is a reason why many Italian companies have legal HQ in Netherlands or Luxembourg), small companies, artisans and freelancers usually avoid to pajly VAT

> while a part is decided by the political side

Now, roughly one third of CSM members is nominated by the Parliament and the other one is elected by judges, according to the "correnti" (a sort of parties)

> The government is pushing for a constitutional amendment to help "fix" this feature. There is going to be a referendum on the change very soon.

Italian here. It's not like that: the referendum is about definitely enforcing the career separation about public persecutor and judges. Actually they are under the same authority and the member of this authority are elected according to a sort of political parties (unique case in the whole EU) and this creates some distortions in career growths and nominations. The new schema will create two different authorities and the members will be selected according to a ballot.

A similar proposal was made by the left wing parties few years ago, when they were at the government

In Italy, if you are charged of tax evasion, you need to demonstrate that you are not evading. It's called "inversion proof"

Please use an appropriate filter for the band that you are transmitting, otherwise you will pollute all the near frequencies with spurious.

Nothing against EV, but a full electric Ferrari is almost a profanity IMHO.

> And it's particularly funny that Borsellino is now in the "saints" category, when he was explicitly namechecked by Sciascia himself in the newspaper column that originated the term "anti-mafia professional".

If you read the original article from Sciascia [1], you can understand that he was complaining about the risk of judge appointments drived by anti-mafia positions, more than competence.

> Saviano, however, is just a specialized journalist.

If Saviano is only a specialized journalist, why is invited in many public talk-show where the topic is different from Mafia?

It's not about the year of birth, it's about the role. Saviano creates his own career with mafia and now is acting as opinionist to any other option (i.e. now about the constitutional referendum that "will enforce the mafia").

Falcone, Borsellino, Livatino, Don Puglisi (just to mention people that paid with their own life) fight heavily against mafia, but they never converted this fight in a career.

Saviano is exactly one of the "antimafia professionals" that Sciascia complained about.

Is there any info about the modulation/encoding/frequency? It would be great to have an open source decoder for RTL-SDR like we have for NOAA or METEOR.

Why not using MQTT? A Lambda that fetch new comments from HN, parse them into Markdown and push into MQTT; the ESP only needs to subscribes a topic on MQTT and render the messages.

I have been worked for a regional ISP 10 years ago and having an architecture like that one, would be a godsend. With centralized BNGs we were not able to apply upstream QoS policies for subscribers on the backhaulings and we had to apply policies on DSLAM access ports.

We ended using a couple of cheap Mikrotik as PPPoE concentrators for every access room, in a similar way as you did. But the reliability of Mikrotik routers was not the best

> In rural areas and using low frequencies, I believe they can even be larger than GSM.

In Europe GSM is going to be dismantled. And techniques like beamforming and radio resource management reduce the power consumption for 5G base station and phones.

> No, the last CDMA based cell standards were 3G/UMTS and the Qualcomm equivalent (CDMA2000 or what it was). From then on, it’s all been OFDM.

Even if 5G is using more advanced modulations like OFDMA or NONA, the concept is the same if you compare the with FM used by walkie talkie: those are modulations way more effective in term of energy and information effiency than a traditional FM transmission
