Maybe what is even worse in a way, is the state of many developed countries where all the coruption is well documented in media, everyone knows what is going on and yet it does not really move people. I guess until you are in "good enough" state you are not forced to really fight.

Would be great to have this kind of internet in box but for 90s or 00s internet.

Hi All, author here. I'm little bit surprised to find my blog here. If you have any question feel free to ask!
drmacak··on A.I. imagery may destroy history as we know it
Yes, exactly I remeber when I was younger and experimenting with lucid dreaming, when I spotted something weird I checked my hands and told myself "ten fingers, not a dream" every time. And trully when I was dreaming my hand was deformed, so if I paid attention to it I could start lucid dreaming. So maybe we are not that much off with NN
drmacak··on What “work” looks like
It actually does not matter what work looks like the important part are the results. I think that's generaly one of the worst problem at job. People being "busy" without any results and people that seems to calmly delivere. Usually management favors the first kind as it feels like no struggle no work is being done.
drmacak··on The Wendelstein 7-X concept proves its efficiency
As I see it the problem is also in approach to big new projects. Usually you have long careful preparation to build something about what you have no clear idea how to do it, since it was not build before. But investors, in this case usually government, wants to see some classical project, with schedule / waterfall but in reality it should be more, as what mentioned SpaceX is doing. Which as I understand is fast iteration on unclear solution with clear goal. But I can understand that investors prefer to have ordinary projects as it is more classic approach. The issue is the way it works every time is the same. Project starts everything is fine. Some small delays on milestones but OK, then someone finds out that state of project is actually much worse than expected. Director is fired and the cycle starts again. On the end there is somehow working somehow done project.

Hi, thats amazing! I was trying if it would be possible to find the software or the cables somewhere hidden on web. But it's looks like there is nothing. This was actually the motivation for the blogpost in case someone want to the same thing, so he can get the informations.

I still feel that only EV is not the answer. You have also get the electricity somewhere so some investment in modern nucler power plants and fusion would be even better then just blindly pushing EVs.
