bitcoin 2018 highlights/ overview/ top links

hi all. bitcoin had a wild, rollercoaster year. it seems to have hit some massive threshhold/ tipping/ turning point last year. saw a bitcoin ATM briefly at a mall this year during the huge bubble in the 1st half. the ATMs spread all over the country, and theyre probably down to a fraction of what they were. a sign of the times.

it looks like its starting to level out/ stabilize by the end of the year.

a cohort at work told me that “bitcoin sounds like a science fiction novel at times”. have been telling others that. its really neat to have 1 thing in life that defies the status quo, expectations, groupthink/ conventional wisdom, the Establishment, “consensus reality” etc… do believe that in the 21st century cryptocurrencies will have an extraordinary far-reaching effect on human social systems eg govts, corporations etc… aka all The Powers That Be™.

there is some idea of a “Digital Autonomous Organization” emerging and its more than paradigm shifting, its revolutionary, a worldwide gamechanger.

am hoping it will involve building a more humane system. so-benignly/anodynely-called “late stage capitalism” capitalism is a house of horrors, increasingly nightmarish/ dystopian/ even verging on apocalyptic. adam smith would be horrified at the “invisible hand” turned to “iron fist”. and our political system has failed to reign it in, because its fundamentally compromised.

so actually a more humane system is increasingly no longer optional. the future of the human race depends on it.

one might think this is a “mere” emergent/ mindless accident or “unintended consequence”, but decades of study have revealed to me/ others there are hidden architects of our “neoliberal” system, and they seemed to know exactly what they were doing. it was designed to create maximal inequality because an equivalent synonym not well recognized is “power imbalance/ power seizure”.

bitcoin will force them out of the shadows (already happening to some degree) and a day of reckoning is coming. am foreseeing/ predicting some pain, possibly quite serious, but freedom and integrity will win out in the end.

bitcoin is one of the most extraordinary inventions of my lifetime. and have seen a lot by now, have been making some lists on this site. lived thru the dotcom era. bitcoin reminds me of the good old days. silicon valley bumper sticker: “please god just one more bubble!”

bitcoin is a foundation and many very dynamic innovations are being built on top of it, some of it can be seen at the moment but suspect there will be key advances that were not foreseeable by anyone.

collatz mod3

ok, this is a sort of shocking discovery at the new year. it is almost obvious to look at properties of iterates wrt remainder by division. there was a years-ago look into factorizing. also there are years-old looks at the bit (base2) diagrams, and this was adapted to do base3 diagrams, but didnt notice anything unusual and left them unwritten-up. did not notice this until just now, but it might have been in those visual diagrams. was looking at some older glides associated with mix30d. was curious about the mod3 behavior intra glide pre/ post peak, actually wondering about existence of repeated 3 factors. was quite surprised to find this major discrepancy/ differentiator. randomly sampling/ spot checking, these glide iterates were never divisible by 3! also, for the other two mod3 values, the distributions are different over the iterates pre and post peak. for climb the mod3=2 case is about 3x the mod3=1 case. for descent the ratio is closer to about 1.5. this is demonstrated in this simple code.

cybersecurity 2018 trends/ zeitgeist top headlines/ links

hi all. 2018 was a very intense year from a cybersecurity standpoint and cut very deep into US politics with the Mueller/ justice dept investigation of russian propaganda efforts during the 2016 election.[b] hard to believe its already 2yr ago. the phrase boiling cauldron comes to mind. still daily impact and still not fully played out yet. suspect that there will be major congressional action in the near future.
