I tried to build some TENS device, but lost in "safety maze".

I reverse engineered some existing device, there are TONS of safety measures.

At least: current limiting resistor, transformer, voltage/current feedback, GND isolation, MCU protection.

After replicate all of these, I still not brave enough to try it myself, I just find it too dangerous.

PS: TENS device is fun. article seems like a bait.

I have also tried to upgrade home lamps. But instead of "smart", I choose simplicity. Using MDNS (local network discovery protocol) and a minimal HTTP interface, I made lamps discoverable and controllable offline via a basic Android App. No central servers, subscriptions, or cloud dependencies.

The result is pure freedom. Setup: plug in and connect to Wifi, done. Control: install app, join home network, control lamps anywhere in the house. Automation: A lightweight, customizable app handles everything.

The app polls locally for available lamps, which works flawlessly for 5-10 devices.

Security might be a problem, but since everything lives behind a firewall, I’m comfortable with the tradeoff.

A funny insight about Platonism (if it's not funny, treat this as a bad joke)

I think aka "∅" therefore I know I thought aka "{∅}" therefore I know I knew I have thought aka "{{∅}}"

and ...

boom! The entire Math system is imported. (BTW, limitations known as "computation theory" is also introduced)

So maybe we are actually mathematical being on a manifold named as "real world". To me it is more concise and profound than "philosophy". As we are real, so do all mathematical objects.

Maybe some logic honeypot would be good, such as a infinite content paging list with some random trigger hidden at pages with non-sense titles. When one IP hits these triggers, it is automatically banned.

Bots will trigger it by walking through all pages, but real human would not click in since the paging is non-sense and titles are non-sense.

One solution could be:

If you volunteered to be acknowledged as a genius, you must open your status. You wear special shakles which is salient and observable to everyone paying the resources directly or indirectly. You shouldn't be allowed to physically protect yourself to your surroundings or you lose the genius status. (or under some absolute physical restraint or suffering verifiable by everyone). Everyone could challenge you at court with sound evidences, which is judged by random sampled jury group by laws well established in future.

With that I could trust to give them "life long resources" to give us "prophecy".

Works but not working through some proxy. A rare but interesting edge case

SQLite is good and open source. I've tried MariaDB on a Python project. The connector has bugs very hard to debug. I tried to download the python source, C++ source and failed to locate the bug. I tried to add issue but find nowhere to report. Finally I give up and use MySQL instead. It works like a charm. Open source adds value, but IMHO being good is first priority.

The creepiest is that whenever there is a discriminant network for judging/identifying sth, there is a generating method taking advantage of this network to make artificial one to fool the network. That means, one day we can take advantage of 3d-printing to make face masks to disguise as anyone, making anyone's voice, and making anyone's handwriting. The existing identity system will total break down. (I'm from China, here exists a kind of company which loans to you solely by ID card scan and webcam verification. Just imagine one getting lots of loan using stolen ID cards and artificial realtime face swapping videos and artificial voices) Apologies for bad English

There's no money in 3D printing, and also, no money in everything since everything can be made by this Universal Making Machine. This article's argument is nonsense. If the Universal Making Machine is made, not there's no money but money can be abandoned. One can use this machine to get anything he want, so why we need money anyway?
