@mattblaze AFAIK the only group to discover Ken’s hack was us in PWB/UNIX. One of the other guys noticed C prepreprocessor had gotten bigger, looked at binary namelist, found symbol not in source code. I got onto Ken’s system, found the code, very clever.
@mattblaze A bit latet, I was in Lab 127’s terminal room, talking to dmr or bwk, and overheard amusing conversation between ken and Robert Morris Sr, who sometimes consulted for NSA.
(RM Jr of worm fame was just a kid then.)
@mattblaze They were chortling away over cleverness of exploit. Then one (must have been ken) said “think we could put this over on NSA?” (which already had UNIX systems... we did favors now and then).
More chortling, then (must have been Bob): uhh, NSA really doesn’t have sense of humor.

CB0.1 Two fine books arrived Tuesday, the first recommended to me a few days earlier by @ProfPCDoherty, the other I’d pre-ordered months ago. I was amused to find on the first page of their Preface, @CT_Bergstrom and @jevinwest a quote Frankfurt's book, a classic I'd missed.
CB0.2 These will join the stack I sometimes use as examples of influential books on critical thinking.
As @CT_Bergstrom has noted, there are issues with Huff’s book for current use, but I included it for historical significance.
CB0.3 The following has substantial excerpts, Table of Contents is shown here:
penguinrandomhouse.com/books/563882/c…
The authors teach to (lucky) UW college students, but it could be good start for a high school course that *everyone* now needs.
I'd call it "Defense against the dark arts."

@Cloudflare SSV1/More to the SIGSEGV story.
UNIX 1970/71 was implemented on PDP-11/20s, which had no memory mapping of protection, although BTL research later got an 11/20 with the KS-11 mapping option:
bell-labs.com/usr/dmr/www/pi…
bell-labs.com/usr/dmr/www/od…
@Cloudflare SSV2/UNIX Third Edition apparently didn’t have signal(II)
bitsavers.org/pdf/att/unix/3… Unsurprisingly as few PDP-11/20s in Bell Labs would have had KS-11s.
@Cloudflare SSV3/Ken & Dennis got early PDP-11/45, which had real memory management, rewrote kernel in C, and signal was in 4th Edition, the one I started with in Fall 1973, ~same week as we got our 11/45 for PWB/UNIX. Sadly I’ve misplaced/lost that manual, but:

i1/ 04/09/20 @Bob_Wachter @UCSF Grand Rounds
(April 2 = typo), about 80 minutes.
He mentions past 2 Ground Rounds have gotten about 100K Views! Desire for good information.
This whole session is relatively low in medical jargon.

i2/ Update on COVID-19, at UCSF and around the Country
This is mostly status report, which change rapidly.
Image
i3/ What do we need to do to return to the “life we aspire to”
This is really important, and not often seen in status slides.
Watch this discussion if nothing else.

h1/ Trump needs COVID Conqueror PR scheme for reelection:
Hydroxychloroquine (HCQ) for masses, avoid controlled clinical trials.
Most people have mild cases or recover anyway, but many who take HCQ will swear Trump saved them,
although sugar pill might have worked as well. Image
h2/ Visual representation of COVID Conqueror scheme.
HCQ has side -effects, requires great care with dosage.
Real experts are very cautious, want trials.
Trump makes it harder:
Doctor: trial? We’ll randomly give you HCQ or placebo.
NO, I want Trump’s drug! (already occurred). Image
h3/ I’ve done follow-the-money exercises, with Trump always worth checking, don't think I discount that,
but getting reelected is worth FAR more than any possible $gimmickry with a few drug companies.

f1/ Trump keeps pushing people to (Hydroxy)Chloroquine.
I’ve been collecting & annotating credible information from @UCSF experts on COVID-19, as it appears, in the subthreads of
CV1-
This thread selects those relevant specifically to HCQ & CQ.
f2/ 03/19/20 @annieluet discussed potential treatments of COVID-19, in internal meeting primarily geared for doctors. I’ve annotated to help general public.
Take a quick look at the tweets, then watch video of her presentation.
a5-a10.2, a13
f3/ 03/24/20 This is part of a 28-minute interview @Bob_Wachter did with @annieluet, very useful as she had time to explain more, easily accessible to general audience. I learned from whole thing:
b1-12
but see especially b5-b6 on CQ/HCQ : NEED TRIALS.
