Doesn't Goomba fallacy require at least one opinion should be minority?

What you want is warning when certificate expiry in next 7 days, then everyone would update before the warning.

Yeah but my point is sometimes suboptimal parts can give better overall results. ( Considering also bad actors )

Because there will always be bad actors. You cannot design a system on all actors' full cooperation.

Ofc they share the blame, but it is not solving the problem.

You can say for example: loan sharks are bad for society; so government gives anyone 0 percent credit. You just removed one problem, created another.

Just and sustaining system with individual morality is destined to fail. Only option is social regulation. Which is at government level.

Yeah but this is a system problem; if we had this utopic system from the beginning we would not even have AI probably.

This was not my point at all. Maybe I could explained better, but main criticism I have is: you can bundle together objectives ( which are inherently good ) and create an utopia. But those cannot always be achievable.

Everything in life in trade-offs. Simple example is speed/quality/cost. I can tell easily:

- services should be cheap - services should be fast - services should be high quality

Now I created an utopia. Obviously this is amazing to listener. They agree. But is it achievable?

It is not saying greed is good or might makes right. But system means you need to construct from this ideals best outcome ( which comes at some trade offs)

The thing is why that this feels so good future is; it is a system with no constraints. A bit like Star Trek universe in Roddenberry's imagination. This kind of utopia can only be achieved with all honest actors, but in reality systems are usually designed around bad actors.

Even with all morally good actors locally, there is no guarantees for external forces. Thinking it hypothetically, even with global coordination ( all good actors ) there is not a proven path that would lead us to better place from any starting point from past.

I started with c64 but stuck there with basic ( extension port was broken unfortunately could not dive into assembly there )

Then I got from someone an old 286, ( hdd was not working ) spent most of my time on "debug" command. Then I got a book for x86 assembly and DOS (interrupts etc). ( Which was kind of hard on non-english speaking country ) I still somehow recall some pages from memory :)

Dived into cracking/cheats, made even money on password recovery. How long those x86 knowledge carried me was unbelievable when I look back.

Copyright itself is a complex subject, when you apply it to code it gets more complex.

ah sorry, when I was debugging I changed the endianness.

  0x9B530150 -> 0x5001539B ->
  01(year_1) 010000(flags) 00(hour_2) 000001(minute) 01010(day) 011(hour_1) 1001(year_2) 1011(month)
  month 1011 -> 11
  year  01 1001 -> 25
  day = 01010 -> 10
  hour = 011 00 -> 12
  minute = 000001 -> 1


 with no endianness change should be: 

 1001(year_2) 1011(month) 01010(day) 01100(hour) 000001(minute) 01(year_1) 010000(flags)

 with your data:

 1001(year_2) 1011(month) 01010(day) 01011 (hour) 000011(minute) 01(year_1) 010000(flags)
 
 16+9=25       11            10        11              3

I think this is the format, some parts are split ( maybe some obfuscation attempt )

0-4 month 4-7 year 8-10 hour 11-15 day 22-23 hour 24-29 flags 30-31 year

Isn't this same as Fortnite windows situation?; windows allows exe but Epic still forces the store.

I think it is more for overstays. Years ago when I asked about my stayed days ( I was traveling a lot ) , border guard took passport and tried to count then gave up

> From my point of view, the issue would be if the same phone worked with the same technology over the same mobile network when connected via a carrier A but the same phone on the same network refused to work with the same technology when connected via a carrier B.

But thats the whole point of carrier profiles ( If I didn't understand wrong. )

Eventually it is the carrier who decides what you can do. ( this can also may be related to deals they made with manufacturers )

I think in this case, it is just missing carrier profile. ( which is like a config file )

I think it depends; speculating but probably volte is a very complicated spec with many optional enhancements ( think ssl with cipher types )

So carrier can choose to whitelist/blacklist phones depending on extensions available

Yeah but those times were easy. Now drivers are binary blobs and firmwares basically.

I meant a bit like: Let's say you have 2 mobile phone operators in your country ( duopoly ) we are ok that for example using SMS for banking interaction ( second factor etc )

I think this is a process; and somehow slowly people accepting those levels, and in a society it becomes normal ( to have whatsapp for friend group, to have facebook for family photos etc etc ) and you are being left out eventually if you are outside of those norms.

So it is not so different for bank to require something like google provided software.

I think it is kind of levels:

"can't participate in society without a mobile phone" "can't participate in society without internet" "can't participate in society without google"

not sure where is the logical correct threshold making it wrong. because we all accept maybe people not participating without internet.

That is totally fair.
