a111: Logged on 2017-07-13 14:31 andreicon: just looking around, i was actually
thinking of switching from my current debian installation
to something more exciting
mircea_popescu: anyway, splendid article.
this is what articles should aim
to be.
mircea_popescu: "The
TCVCXO is good; but not quite up
to GPS standard when operating un-boxed in windy locations. Blowing on it displaces
the 10.000000 MHz crystal oscillator by around 1 part in 10 million or 1 Hz, which is magnified 150
times by
the synthesizer PLL.
This is enough
to momentarily unlock
the satellite
tracking loops, if done suddenly."
phf: that fpga receiver is also
technically an illegal device. i don't know if
that's in
the same article, but consumer gps is supposed
to cut off signal when
traveling above certain speeds or certain altitudes (i don't remember
the specifics
though)
mircea_popescu: "Mixing with
the same code in
the correct phase de-spreads
the wanted signal and further spreads everything else." << if
this isn't
technology i dunno what is.
mircea_popescu: actually great article, re
the whole "extract signal from below
thermal noise floor"
thing.
phf: no, he linked a discrete
ttl forth machine by
the same guy
mircea_popescu: and since we're
talking of fruit and here, let's
take a detour into pina colada.
the way
to say ass in a sexy-friendly way is cola, which is why
the sort of jeans
that put out
the girl's ass are called levantacola. so now... pina colada should
thereby be
translated "hourglass pineapple".
mircea_popescu: oh also : let it be said
that
there are few luxuries more luxurious
than
this
thing whereby you point out
the window, "see?
that one!" and half hourish later you're hacking up
the very fruit in question.
they do make iiiiincredible fucking pineapples here.
mircea_popescu: the finer points of forum scheduling still elude me. but nevertheless -- let it be said each dog wil lget his day in
the sun and nothing will remain buried in
the logs, forgotten. so.
mircea_popescu: phf sorry about
that. in retrospect i picked
the worst choice, not even on
the menu. should have just made a short hi and
then decided.
mircea_popescu: i have nfi what
to do now, continue conversation node way back, go
through
the logs, re-read
the short range here...
mircea_popescu: but, in correct
terminology, it is very directly v-for-thought, and nothing else, and no more. "i
thought i was writing code" "where's your press ?" "fuck. i understand now i was actually, and literally, and without remainder, just pouring sand on my dick for
the novelty of
the sensation, exactly like 3 yo first-time-at-black-sea does!"
a111: Logged on 2017-04-05 14:25 mircea_popescu: Framedragger so if it does not make
that statement, it imports, like any research paper EVER,
the following "the authors have conducted a full review of extant literature relevant
to
their
topic, and swear
that
the following list is complete and correct :"
phf: i
thought maybe you have one of
those '99 home pages by a electrical star
tracking aficionado
phf: asciilifeform: you have any links re "electrical star
tracking"?
phf: it's one of
the reasons i started looking in
this direction. obviously gps is inadequate for wasp stack
phf: i
think a good exercise is
to rewrite one of
the existing c machine subtrates from cmucl or sbcl in ada. but left for another lifetime
phf: right, motion planning also
the part
that's non existent in above code, so easier
to greenfield, where's avionics is
there in however poor form
phf: i'll use your device and claim
that
the comment was "for
the log readers" ;)
phf: note
that
the actual output of
the system is servo motor commands
phf: i won't
the
thing
to follow some pretty simple decision algorithm: here's a gps list of viable landing spots, here's a gps list of interesting
targets. given your positional knowns decide and execute a flight path
that'll
take
the aircraft
through highest number of interesting
targets before landing in any one of
the viable landing spots. surprisingly large number of moving parts in a situation like
that
☟︎ phf: well, if you can write me an avionics code
that will do all
the
things (figure out
the position of aircraft in space, both on micro i.e. in relation
to earth's surface and macro i.e. gps levels, knows how
to adjust
that position both in normal operational and critical situations, etc. etc.)
then i won't have
to study existing ones either
phf: you studied
them never
the less
a111: Logged on 2017-07-13 16:04 asciilifeform:
this is
the funny bit : i learned by studying from horrifying cruftsmen
a111: Logged on 2017-03-29 18:09 asciilifeform: but it remains,
to demonstrate experimentally.
phf: that's unrelated
to my point
a111: Logged on 2017-07-13 16:14 phf: but ffa also doesn't have
that many moving parts. it's a single stack mathematical code
that mostly operates on same, uniform memory regions. so my original issue was
that
there's no enough quality code, certainly plenty of shit code, which is not quite
the case in common lisp world
BingoBoingo: <asciilifeform> ( if you were switching on a genuine 51%tron, would you announce it in advance ?! ) << It's
the one where
they
talk derps into client
that forks by rejecting mined blocks
phf: but ffa also doesn't have
that many moving parts. it's a single stack mathematical code
that mostly operates on same, uniform memory regions. so my original issue was
that
there's no enough quality code, certainly plenty of shit code, which is not quite
the case in common lisp world
☟︎ phf: ~for me~ studying ffa is a faster method
to pick up good habits, shed bad habits, considerably more so
than say studying
that avionics code above.
phf: i
thought
that proper classical education is all about learning how
to discriminate? i mean western art has
this value of "this guy is good, but not quite.
this other guy is as good as
this first guy, and he also has
that not quite covered. he's
the
true master"
☟︎ phf: and
the habits
that i do pick up would be eliminated in
the next round of learning
phf: i can learn from
that avionics code and possibly not even pick up
too many bad habits, but i doubt i could've done
that 15 years ago
trinque: most important bits probably in youth, i.e. beatings for
the hint of lying shitbag.
phf: sure, but you can do
that if you ~learned
to discriminate~
phf: you improve your craft by studying from master craftsmen. if you've studied
too long in from poor craftsmen, never developed
the skill
to discriminate, etc.
then of course you're going
to be poor craftsman yourself (and possibly unteachable)
a111: Logged on 2017-07-13 15:58 mircea_popescu: i can
teach sanity
to rabid street urchin within months and
to rachel from jewish middle class home within years.
phf: i don't understand
the points
that you're both
trying
to make
☟︎ mircea_popescu: no, it's why i gave up on
the notion. djb is
too old
to be worth it, just like 35yo woman caught in wild.
mircea_popescu: speaking of which,
teh dungeon calls ; i shall be back in a coupla.

to rabid street urchin within months and
to rachel from jewish middle class home within years.
☟︎ mircea_popescu: you know
the joke about
the ny plumber who has a price for fixing a faucet
that broke, and a different one for fixing a faucet you
tried
to fix ?
phf: you gotta study
to get
to
the point where "it's a simple matter of".
that's
the kind of insight
that reading ffa can give you
mircea_popescu: who aren't nearly as well selected or invested into
their own mental life.
mircea_popescu: which is how you get
talented souls who evidently put
time into it, like say djb, or like say blum, being dumber
than
the l2.
mircea_popescu: and if he went
to an establishment supported by pantsuit money and dedicated
to
the encouragement of shit sloshing, he could spend any amount of
time and effort NOT IMPROVING
mircea_popescu: this is because he actually lacks
the capacity
to discern
thought from
the dumb shit he's doing ; not because he's not
thinking enough.
mircea_popescu: he
thinks, in
the portable latrine he carries above his shoulders,
that such nonsense is
the result of a
thought process,
that he's
thinking, you know, at me and etcetera.
