Xah"s Edu Corner: Under the spell of Leibniz"s dream

Dear computing comrades,

Today, i'd like to show you a piece of literature written by a eminent
mathematician Edsger W Dijkstra.

Here's 2 interesting quote from his letter:

â€=9CThe prevaling attitude was reflected in the creation of two litera=
ry
figures â€=94 admittedly of rather poor literature, but nevertheless of
great paralyzing power â€=94, viz. â€=9Cthe average programmer=E2=
€ and â€=9Cthe
casual userâ€=9D. Up to these days, academic research in programming
methodology has been supposed to respect the severe intellectual
limitations of these fictitious morons: consequently any proposal that
required any further education of the programming person was out.â€=9D

â€=9C... On the other hand we should be glad that the gospel of design =
by
derivation rather by trial and error is still preached.â€=9D

I happened to read it today. And, i think in your busy schedule of
checking out slashdot and blogging and driveling with your excitement
and concerns about current fashions and trends with your fellow peers
and factions; It is good once in a while to read something
unfashionable and not for-dummies.

This letter of EWD is about 16 pages.

Is somewhat a quaint rant. The first half i find interesting but
without much sympathy, perhaps because the author is mostly talking
about the situation in the mid 1990s, of which, i'm unfamiliar and too
early a period to touch me personally. But the latter part of the
letter, i find much empathy and concurrence. In particular, his
remarks related to the formal methods.

(for you math illiterates out there: the â€=9Cformalâ€=9D here does=
not mean
the opposite of â€=9Cinformalâ€=9D, as in â€=9Cformal dress=E2=
€ vs â€=9Cinformal dressâ€=9D.
Rather, â€=9Cformalâ€=9D here means â€=9Cmathematical reasoning=
by symbol
manipulation; the â€=98FORMâ€=99 in math FORMulasâ€=9D. (for yo=
u mathematicians
out there: the root of the word â€=9Cformalâ€=9D as in â€=9Cfor=
mal dressâ€=9D and
â€=9Cformalismâ€=9D, actually are the same. They both refers to =E2=
€œformâ€=9D as in a
empty shell, appearance.)) (So, when you â€=9Cdress up formallyâ€=
=9D to attend
your friend's wedding or death ceremony, it literally means you are
putting on a appearance.)

Now, without further ado, the article is at:

Oh dear God, please *don't* remind me.

A link to a copy in a non-toxic format would be nice.

Well, the fact of the matter is that the bulk of Dijkstra's
"EWD" papers were written *long* before the web existed, typed
on a favorite manual typewriter which he continued using for the
remainder of his professional life.
has more details on the more than one thousand "EWD"s he wrote.
Until very recently, the *only* source for these documents was
either in hardback technical books (for the few that were published)
or in the PDF bitmaps of scans of the original manually-typed pages,
which the University of Texas at Austin has generously made [and
even after Dijkstra's death continues to make] available on-line.

However, a *few* but "growing number of the PDF bitmap documents
have been transcribed to make them searchable and accessible to
visitors who are visually impaired." If you would care to volunteer
[as over sixty others have done] to contribute to the transcriptions,
see .

Otherwise, just count your blessings that these gems are available
at all...

Please, Xah Lee, could you possibly stop to "explain" things that are
absolutely trivial? If somebody has doubts about the etymology of a
word, he may use the dictionary, or he could ask.

I used usenet years ago then stopped for couple of years. I remember
seeing him/her on c.l.perl I believe doing the same thing he/she is
doing atm. I'd say the ultimate usenet superstar. Wow!

I think it's some (probably mild) form of autism.
No offense intended, Xah.

Yeah, yeah, that's what they all say, especially when they do that
most-common of usenet things -- insult your mental health and tone it
as if it were a very compassionate and understanding suggestion to
seek medical treatment rather than the flame that it is. :P
