cyber 2017, milo yiannopoulos, pewdiepie, online content, other zeitgeist

hi all, two recent high profile events caught my eye, #1 the meltdown of Milo Yiannopoulos and #2 piediepie losing a lucrative contract with Disney for his controversial youtube content. these seem to me to be strongly reflecting current cyber zeitgeist in various ways. so, a release of another/ the latest huge batch/ selection of items/ headlines.

in case #1 its “live by the sword, die by the sword”.[a] yiannopoulos reminds me of british commentator piers morgan who made a big splash years ago with his biting/ acerbic analysis of america, but seemed to burn out from his high profile/ near-trollery. did not track milo much at all but his downfall splattered very heavily across sites regularly browsed. it seems like a case of “troll culture”. theres also connections to the video game area. and of course, intense connections to current politics/ Trumpism which is still impacting cyberspace with roiling waves.[i]

collatz, tightening screws on general invariant

this tightens the screws some )( on the prior findings and show they generalize nicely. prior analysis seems very solid but there is always the shadow of question of bias in the generation algorithms which start from small seed sizes and build larger ones out of smaller ones. an entirely different strategy for generating sample seeds is used here based on a genetic algorithm. the idea is to start with a fixed bit width and alter the bits in it just like “genes”. fitness is based on glide length (or equivalently ‘h2’ for a constant seed width). it starts with 20 random parents of given length. there is 1 mutation operator and 2 crossover operators. 1 crossover operator selects adjacent/ contiguous bits from parents at a random cutoff/ crossover point (left to right) and the other just selects bits randomly from parents not wrt adjacent/ contiguous position. fit24 is again used for the linear regression fit. these runs are for 50, 80, 100 bit sizes and ~200 points generated for each. 50K iterations.

because of declining # of points for higher widths, this is circumstantial evidence that as widths increase long glides (relative to width, ie ‘h2’) are (1) increasingly hard to find and/ or (2) rare. these two aspects interrelate but are not nec exactly equivalent. hardness of finding seeds with certain qualities ie computational expense does not nec mean theyre rare. an example might be RSA algorithm. finding twin primes is somewhat computationally expensive (although still in P) but theyre not so rare. technically/ theoretically rareness and computational expense are related through probabilistic search aka “randomized algorithms”.

russia election hacking, trump+obama+putin, fake news

hi all, what a blur its been since the last cybersec post here. US obama admin announced sanctions against russia in response to intelligence agency consensus that Russia hacked US election as part of state govt efforts, and intended to get Trump elected. wild info! the repercussions continue to fall out, it looks like congress will be all over this issue for months to come at least, and maybe years.

the trump admin hostility toward the intelligence agency apparatus is remarkable/ extraordinary/ unprecedented. when the mainstream media starts to talk about the “deep state” you know that its a new world we’re living in.

the actual evidence that russian govt was involved in the hacking does not seem all that strong to me, it appears to be more assertion by widespread consensus, which is questionable to say the least.

this stuff hit the Full Trifecta over Obama,[d] Trump,[c] Putin[e] / Russia.[b]

theres a lot of continuing headlines on fake news, and it looks like maybe the concept is not going to go away with the election and is a new concept in the collective consciousness.[f] apparently a permanent gamechanger.

apparently as stated earlier, the age of cybersecurity/ infowarfare is on us in full force. dizzying times we live in at times so to speak.

bitcoin 2017 starts with a bang

bitcoin_wraphi all. havent written on bitcoin in awhile. its surging in value at the beginning of the year. this isnt the first year that happened. a set of favorable circumstances is propelling it. it is known that china regulation has a lot to do with its value and that there are a lot of chinese holders. it appears that chinese regulatory climate looks newly favorable.

another pattern is that whereever there is economic crisis in a currency, bitcoin surges.[f18] it seems that theres always some kind of monetary crisis somewhere in the world, and bitcoin capitalizes on it. there is that old saying by rahm emanuel, “never let a good crisis go to waste”. a bit machiavellian sounding, yet bitcoin seems to embody some of this. another way to see it is as a sort of ambulance that shows up at bloody scenes.

it looks like the media has gotten past the wild alarm and surprise over bitcoin. maybe part of the hype has subsided for the moment. theres less feverish reporting on it. but that does not fully capture its steady pace of innovation.

collatz radial basis function back to basics

hi all. some extended wallowing in self appraisal/ reflection to begin with in this installment. last months installment of collatz had a big highlight, at least wrt this blogs history.  as has been stated in various places, & trying not to state the obvious here, part of the idea of this blog was to try to build up an audience… aka communication which (to nearly state the almost-canard) is well known to be a “two way street!” there are all kinds of audiences on the spectrum of passive to active, and in cyberspace those in the former camp are also long known semi-(un?)-affectionately as lurkers.

must admit do have some “blog envy” of some other bloggers and how active their audiences are wrt commenting. one that comes to mind is scott aaronson. wow! thought something like a fraction of that level would be achievable for this blog but now in its 5th year, and candidly/ honestly, it just aint really happening. have lots of very good rationalizations/ justifications/ excuses for that too. ofc it would help to have some breakthrough to post on the blog and drive traffic here through a viral media frenzy… as the beautiful women sometimes say, dream on… ah, so that just aint really happening either. 😐

however, there was a highlight from last month, for this blog something like a breakthrough, but also, as you might realize the subtext on reading further, with some major leeway on where the bar is set (cyber lambada anyone?). got an anonymous, openminded, even almost/ verging )( on encouraging comment from someone who wrote perceptively and clearly had a pretty good rough idea of what was going on in that significantly complicated collatz analysis blog post as if reading substantial part of it and comprehending it, and getting to some of the crux/ gist of ideas/ approach here. nice! 😎

(alas, full “open kimono”/ self-esteem challenging disclosure… admittedly that is a very rare event on this blog, and despite immediate encouragement and my marginal/ long gradually increasing desperation now verging on resignation acceptance, anonymous has so far not returned. this overall predicament is something of a nagging failure gap/ regret/ ongoing challenge wrt the original idealism/ enthusiasm/ conception of this blog. which reminds me, also, long ago there was an incisive/ discouraging/ naysaying/ cutting/ near-hostile/ unforgettable comment, and may get to “highlighting” that one too eventually as part of the overall yin/ yang balance etc after changing circumstances and/ or building up enough courage wrt my cyber-ego, long keeping in mind that other quirky aphorism, success is the best revenge…) 😈

anyway here is the comment again, suitably highlighted/ framed/ treasured forever at the top of this blog:

What is a “glide” and how is it related to the trajectory length? Have you defined it somewhere earlier? What are your input variables for the model? What’s the reason to believe that even if you have a good predictor for your “glide” it helps to prove the conjecture?
