Is defeating a 40-year-old copy protection mechanism still illegal under Section 1201 of the DMCA, or have they changed the law to make an exception for "very old" software?

BTW, in the European Union, reverse-engineering is perfectly legal, if it is done to ensure compatibility with the current tech.

I cannot cite the reliable sources for it, though.

It is interesting that the vendor adapts the hardware token and then makes it weak on the software side.

I recently did similar thing for the FineReader 6 using a hardware dongle [0]. It was surprisingly easy, no disassembly at all, just injecting srand(0) and a hardcoding the responses from the dongle. I had no prior reverse-engineering experience at all.

An animated logo is a bad idea.

About the site itself: why would some of these measurements be that high? Especially the really high value in France and the one in Britain stand out.

I guess it is some kind of problem with the home-made counter (e.g., picking up electrical noise), or perhaps the counter is placed in a building with a higher background level.

As far as I’m aware, buildings made of blocks containing coal power plant slag have a higher background, but I don’t know how pronounced the effect is.

The normal background should be like 15–25 counts per minute for majority of Geiger tubes.

I would suggest you to also use English together with local language just like Flightradar

This is not my project, I just submitted it as an interesting website.

Perhaps if the discussion catches on, I can send the link to the website's owner.

He's right. Strengthening of real human presence against in the internet is a noble goal.

When I do/create something I find useful for others, I usually publish it on my website too. I (and probably almost every other developer/tinkerer) benefited from the open-source and the wealth of information available on the Internet so much, that giving some small part back is only fair.

Recently, I started using Marginalia Search as a first choice when researching something technical. Surprisingly, almost always I find a real person writing about their experiences, not some content farm or corporate bland talk.

Poland has a high alertness status for like 5 years now. So there was time to be prepared.

There's some news about some psy-op or some damage every couple of days. We hear about "Russian trolls" and influencing the political discourse.

I wonder if there is any symmetrical response to this happening. How about unleashing psy-ops and "Western trolls" in Runet? Is Europe in purely defensive mode?

It’s crazy that you had access to these technologies during communist period.

Growing up in USSR I didn’t know anyone who would own a PC up until early 90s.

yesturi · 16 days ago
PC-s were only described in hobby magazines, like Bajtek or Młody Technik. Nobody had them, though, except maybe some institutions. The hobbyists used to own ZX Spectrum or Commondore 64, but even that was rare.

I know one programmer in his 50s. He had an access to the ZX Spectrum in his primary school, but that was by effort of his local physics teacher.

Old scanners were SCSI, which made me wonder if you could use them as boot devices, if you could stuff the scanner driver and OCR software into the BIOS. Might be easier now that we have uEFI.
yesturi · 16 days ago
That is ridiculously fantastic idea!

Shame I used to have an SCSI scanner but I already disassembled it for parts.

One can write a simple bootloader, which reads bytes printed on a paper sheet to memory then boots it. Something like: black (0), white (1) or long rectangle (1), short rectangle (0). Wonder about the storage capacity of the A4 paper.

And yet was an absolute marvel of engineering. I often used to wonder at the accuracy and reliability they got out of those stepper motors, trying to imagine the size of the tracks.

Fun thought experiment. The 128 GB SD card on my desk could store a 1-bit bitmap of 1,000,000 x 1,000,000 pixels. Imagine shrinking that down to the size of the die, and how small each (logical) cell is.

Maybe that's the charm of mechanical watches? Precise metal parts moving in harmony. You can entertain yourself with analyzing its workings by simply watching it (no pun intended).

Precise, but featureless digital clocks lack "soul" which you can actually see.
