in spite of my age, I'm one of first digital native. I never used it and nobody explained me how to use. At same time I avoid most of analog instruments: multimeters, scope meters, calipers.

I agree that the ceiling of 4h is correct for high intense cognitive activities and that morning, after few hours after woke up, is the best time for these activities. And I would add that trying to do more the same day will affect the next day.
Meetings, phone calls are distractions, especially in the morning, they could also bring different thoughts far from current task.
To have the best result we must reorganize the company according to this, because most organizations prioritize visibility over results, but compensation, promotion and trust structures reward deep work instead of meeting attendance.

I've carefully read this interesting discussion: some political, mostly about full cloud services (AWS) vs partial EU providers, or lock-in vs indipendence.
I think the problem is elsewhere. The real advantage of big cloud players isn't their individual services. It's seamless integration and simplicity. We need a service integration standard for infrastructure that enables:
- Service discovery
- Networking
- Observability
- Configuration
This benefits everyone: EU companies, US startups, enterprises anywhere avoiding vendor lock-in. A standard letting services integrate regardless of who provides them.
Not just container orchestration (Kubernetes), but something working across bare metal, VPS, containers, and remote machines.

Having used both worlds: a lot of the provided features come with strong vendor lock-in, and in most cases that not, with slightly stronger “local” engineering you can reach the same targets and needs locally.
The more I work (started coding 40 years ago, and data engineering 25 years ago), the more I favor designs that are less coupled to cloud features.
If you do so, the offering in the EU just as it is now is well enough to scale.
In short: more computer science, less delegating to cloud operators, stronger designs.
The irony is that EU education is still broader and more grounded in fundamentals, compared to US one that has become increasingly skills-oriented.
I also prefer to design solutions that are portable and platform independent, cloud providers simplify and hide something to you, it has a cost (not just money) that you cannot quantify on long term and that's clear for who has experience in both worlds.
If we review the history we can notice that there was always an influence from politics/religion to science, literature, arts, philosophy and the use of them by politics, maybe to justify some decision and state of facts.
It helps to empower control over population and fits perfectly in the social and historical context: the emperor blessed by God, the evolution theory, the epic poems, theory of race, the industrial revolution, and modern times don't escape these patterns too, we just suppose to be neutral.

I think that during ice age it was more easy to travel from Sicily to Malta, maybe they'll be able to find traces of humans even earlier than 8500 years ago.
Anyway I think we have a lot to learn from our ancestors, how were they able to move such heavy megaliths?
Security teams don’t fail by missing bugs. They fail by fixing the wrong ones.
Gartner’s EAP category shifts focus from CVE volume to real attack paths across cloud and identity. Most alerts never reach critical assets. EAPs show what actually matters.
> For instance, many chipsets have an integrated FM receiver that is essentially a high-sensitivity VHF radio. By taking the raw audio output and applying a Software Modem (AFSK/FSK) in the user-space, you bypass the kernel/firmware complexity entirely. You don’t need to sideload a modem driver if you treat the audio jack or the internal FM bus as your physical layer.
This is fascinating. Happy to do the research myself, but do you have any recommended reading/sources to learn more about this?
I'm glad you find it interesting. I developed the theory at university, studying how ASK and FSK modems work. To build this, you’ll need to understand the Shannon-Hartley theorem, band-pass filtering, Fourier transforms, and convolution.
For the practical 'how-to,' I recommend studying GNU Radio and SDR++; they show how to process IQ data or raw audio streams directly, and for sure there are other libraries. On the 'ancestor' side, look at the AX.25 Packet Radio protocol and AFSK (Audio Frequency Shift Keying). These are the same 'softmodem' principles used in FidoNet nodes decades ago.
GSM Arena can help you find phones with integrated FM receivers. You'll notice that many features are market-dependent, meaning: the receiver is often physically present but simply disabled by software.
Thanks for posting - this is really interesting. An idea perhaps whose time may have come. Out of interest (no criticism implied) but do/have you use this tech? and if so what was your experience?
I never actually used Fidonet. I started on BBS systems just as the internet was becoming affordable, and I made the switch early.
However, I apply the concepts of FidoNet almost every day. I often design offline-first devices, where store-and-forward logic is a necessity, not an option. Many are deployed in remote areas where signals are never optimal, there a High-Gain Antenna is the only solution.
I also prioritize binary protocols over structured JSON; you have a much higher probability of delivering a few hundred bytes of binary data than a bloated text object when the link budget is tight. Finally, I never expect Wi-Fi to work beyond 5-10m when the router is placed inside the metal structure (that's why my skepticism about BT on cruise ship).
