## embalmed ones

Something I miss from some mid-90's HTTP servers is autolink functionality: when selecting text as an anchor for a hyperlink, a query would be run on what would now be called a CMS, suggesting possible targets. Not only was this convenient for the author, but also for the reader, as it encouraged more informative anchor text than the frequent-at-the-time "this" or "here".

## Linguistics

Lambek's "From word to sentence" notes (pp.79-80) the difficulty of shoehorning languages which use parallel constructions (resp. the mathematician's respectively) to place objects and modifiers, not in a nested order, but in parallel sequence (resp. not order-inverting). Maybe linguists need an equivalent of the zip function?

The 80's cartoon "Mother for a little mammoth" (~8 min) is deeper than it first appears: not only were the ancestors of Mammuthus primigenius to be found in eastern Africa (Mammuthus subplanifrons), but there's a very similar relation (both geographic and familial) between Australopithecus afarensis and Homo sapiens.

... also, despite being equally unsure of what Cheburashka may be, I'd still offer a paw were we to cross in the street!

A 1980's Latvian song contest finalist:

## Rivers and Sunsets

The Новые Самоцветы aren't the only ones doing retro themed videos; Кобзон (who we've previously seen demonstrating willingness to play with intergenerational arrangements) has a current-and-retro-video, "dress":

(can anyone comment on the accuracy of the setting? I'm guessing the flashbacks are supposed to be late 60's~early 70's, a time when Kobzon was certainly active, but as far as I can tell, this particular song was a "song of the year" finalist in 1991 [cf "don't cry"], and hence [however touching] would be a bit anachronistic for either period depicted in this video)

## о русской музыки и кино 3

just ran across the party band Volga-Volga; most of their repertoire is a pastiche of russian pop, but some of it shades into western standards as well, eg:

the lyrics may be Maxime's « Знаешь ли ты », the style balkanized, but the music is clearly a western "classic", or

(a well celebrated "Hava Nagila"), or their punked out extended dance version of "Titanic":

OK, that last was pretty weak. They do much better when covering eastern european party tunes such as "American Boy" ... but that's unlikely to mean much unless one is familiar with both the early 90's original (by a group we've seen here before, Комбинатция) and its various extant pastiches...

## PMRC v CCCP

St. Petersburg recently celebrated the opening of the Rock Club and 35 years of official acceptance of their local scene*, and coincidentally I ran across some official soviet censorship lists from the summer of 1984:

https://pp.vk.me/c604417/v604417769/20099/9An0pVA4zuA.jpg

https://pp.vk.me/c604417/v604417769/200a1/NAAEyfTUS3E.jpg

(one notes that кино, despite having being on the list, now merits a symphonic interpretation ... tempora mutantur)

It's apparently a soviet attempt to "reassess the contracts of musicians who performed violently or sexually in concert, and creating a panel to set industry standards.", but I'm not sure any of the censors (similar to how their US counterparts seemed to have forgotten Elvis' pelvis?) actually listened to the censees.

For example, I can understand how the soviets (who seem to have been even more obsessed than the LDS with squeaky-clean?) would have had problems with the Ramones and Acca/dacca.

And maybe the B-52s got the boot for their name, not their songs. But the Talking Heads? Yes? Asia?

Was there something amazingly subversive about new wave or prog that my white suburban teenage friends of the time completely failed to appreciate?

• not to be confused with the 80th of the traffic police, which ended appropriately enough with a group interpretation of Time Machine's ca. 1979 "Curve Ahead":

Going the other direction is a bit more difficult. So far the best US cover of an RU song I've run across has been Chet Atkins:

Atkins - Очи чёрные

I'm sure you all are much more color-blind, and it's just my old-fashioned XX upbringing that caused me some cognitive dissonance in the previous card's collection of pale guys singing "go down moses", but judging by the parodies, russian radio also tends to segment by audience ethnicity:

БОНЯ И КУЗЬМИЧ - ЗА МОЛОКОМ

on the other hand, although russians definitely have fewer integrated acts than western europe, in certain cases it seems to be due to lack of opportunity rather than lack of inclination:

Валенки.Марина Девятова и Пьер Нарцисс.

Either vampire Jacques Vaucanson or vampire Pierre Jaquet-Droz, however, would be the perfect age, and both of them already demonstrated

• an unhealthy fascination with animating the the non-quick

Jaquet-Droz's choice of writing, art, and music were not haphazard; these were the ways in which aristocrats of the XVIII distinguished themselves from the public.

another question for those of you who actually "made the scene" during the seventies:

Here's ONJ doing a disco cover of Dolly's Jolene.

All that shimmying (during, as well as in between, the verses) reminds me strongly of the 1980's soviet pop I've been watching lately. Is it just that (like Grandpa Simpson's belt onions?) everyone did the song-and-dance thing back then? Or was this limited to Ms Newton-John's interpretation?

## exoteric vs esoteric in computer languages

On a different topic: back in the early days of compilers —when they were just starting to be practically useful, and it was yet unclear if they were even theoretically possible— there was a fair amount of work done with homomorphic compilation, with the idea that to be a homomorphism was sufficiently constraining that there couldn't be more than one, and hence if one succeeded in constructing such a compiler, it would necessarily be the one sought.

(anyone know how to express the above para in a less esoteric language?)

It just occurred to me that a homomorphic compiler is a reasonable counter to Thompson's "trusting trust" attack, on at least two levels:

• as per the reasoning above, a properly constructed homomorphic compiler shouldn't be able to insert trojans (to what degree would this extend to a Scott-continuous compiler?), as that involves a bit more latitude of action than simply composing meanings to determining the meaning of a composition.

• even if one were not convinced that the compiler was fully homomorphic (and that programs were initial, etc.), as long as it was sufficiently homomorphic, one could effectively use "homomorphic encryption": by compiling a conjugated login program, and unconjugating the compiled object, it could be made arbitrarily unlikely that the trojan insertion would be triggered.

(of course, at this point one would still have to trust the loader, the h/w, etc. etc.)

is from "On the cruelty..." and while unicode fonts now give us the opportunity to easily play the syntactic games of the immediately prior paragraph, replacing {True,False} with the less-interpreted {◉,◎}, I have to admit that, some two decades after having first encountered this passage, I am increasingly convinced of Dijkstra's approach, in this paragraph, to semantics.

(the distinction between functional and imperative is largely [cf Hehner] moot at such a low level; his description of the procedure call as a matter of taste is correct insofar as it "merely" provides a shorthand for formulae; and I'd even be tempted to more austerity: booleans are to integers as characters are to strings, while skip is a derived notion, as the identity for the semicolon.

Then again, I am an unregenerate purist: while I can understand that the modern applications programmer might be happy to call libraries, finding bit-twiddling and finite-state machines to be things of a musty past, I don't see how anyone can claim to be a hacker without a fundamental grounding in bits and machines sufficient to abstract to information and automata.)

lambda *x: f(y(y,f))(*x)]
for f   in [Y0(Y0,lambda fac:
lambda n: 1 if n<2 else

The chance that an arbitrary permutation doesn't have any fixed points tends to 1/e.

(is this any relation to the 1/e that shows up in optimal stopping heuristics?)

In the XIX, FMACs were done with springs (and clocked via handcrank):

From when "spaghetti code" was meant literally: how adders could multiply (w/out logs):

Cayley not only introduced the term "tree" (in the CS sense) to the english language in 1857, he did so as a computer scientist:

• his motivation was abstract parses of concrete syntax
• his investigation distinguishes between commutative and associative operations, and
• his trees have their roots at the top, and their branches opening downwards!

Programming Language Theory papers, insofar as they tend to consist of a Grammar (to produce the terms), a Logic (to produce the typing), and some Rhetoric (to explain the previous two), are highly trivial (in the medieval sense of the trivium)

The sequence:

0 → algebra scenes → hollywood movies → profit → 0

I agree that isolation is most important but exercise helps when learning new material. My wife suggested the increased oxygen uptake might have something to do with it; I'm guessing it's more (as in recitation or a lecture) that the exercise demands enough attention that one must concentrate somewhat to actively go over the material, but not so much attention that one's mind can't wander and find new connections.

Believers in Conway's Law would say that spending time at other groups' water coolers may not have tangible immediate payoff; but it may well enlarge the feasible design space.

On a somewhat related point:

Excerpts from How Not to Network a Nation: The Uneasy History of the Soviet Internet

Figure 1: The OGAS Project was developed by scientists in 1960s Kiev that also formed a group that pretended to be an independent country called “Cybertonia”: on the left of this passport is a map of its capital city, Cybergrad. On the right is their mascot and supreme leader: a saxophone-playing robot.

Chapter 5 chronicles the slow undoing of the OGAS between 1970 and 1989. Neither formally approved nor fully rejected, the OGAS Project found itself ... stalemated in a morass of bureaucratic barriers, mutinous ministries, and institutional infighting among a state that imagined itself as centralized but under civilian administration proved to be anything but. ... This chapter frames how hidden social networks unraveled computer networks.

Today anglophones will say "it's greek to me" to indicate something is incomprehensible.

Back in the days when people studied greek, they might have been able to make the same statement, but indicate "this might appear incomprehensible at first glance, but if we concentrate a bit, we can likely puzzle it out..."

if speaking in terms of Principal Ideals is inconsistent, we could always press the cosmological background-cone into service.

Consider the interval between, eg cosmology, and any other concept: we can classify these intervals according to the following schema:

• consequential: one background cone contains the other.

• inconsequential: the background cones fail to intersect, or do so only partially.

• tangential: one concept occurs on the boundary of the other's background cone.

I hope a trichotomous classification of intervals is consequential with regard to cosmology? :-)

## skater 9chka

and, yeah, so far it looks like the early 80's were pretty much sk8er boi's, but (as with anything else soviet?) we also find the skater grrls of this card's title: (that last competition was in Saratov, which, judging by some bibliographies I've read, was known not only for its skaters, but also for its computer geeks)

continuing the retro quotation habit, compare this camera work (starting at 1:26) from 2016's "The Very Best Day":

with a sequence (from 2:10) in 1964's "I'm Cuba":

A late soviet boy band:

On its own not so remarkable, but my band played Misirlou (Μισιρλού) regularly, so it was cool to see Shatunov's friend (first appears at 1:48) wearing a Dick Dale & The Del Tones t-shirt.

The 80's cartoon "Mother for a little mammoth" (~8 min) is deeper than it first appears: not only were the ancestors of Mammuthus primigenius to be found in eastern Africa (Mammuthus subplanifrons), but there's a very similar relation (both geographic and familial) between Australopithecus afarensis and Homo sapiens.

... also, despite being equally unsure of what Cheburashka may be, I'd still offer a paw were we to cross in the street!

Some cognates in the super video "Top" are obvious in the printed lyrics; for others you'll have to listen.

Vorobiev keeps on cranking them out. Not only is this another frame-story clip, but Chekhov's rifle is lampshaded.
