zumatic··on History of Lisp Editing
No, it requires precedence to distinguish between (2 f (3 g 4)) and ((2 f 3) g 4)

> which is arguably how most sane engineers would write it

I'm always wary of this sort of statement.

zumatic··on Despite money and effort, homelessness in SF as bad as ever
More like 3X the area and 15X the population (Tokyo metropolis vs SF city and county) or 1.5X the area and 8X the population (Tokyo metropolitan area versus SF metro) -- all figures gleaned from Wikipedia.

zumatic··on Switching to the Mutt Email Client
I suspect yes, because Lotus Notes was briefly very fashionable for corporate communication, and apparently supported NNTP, according to this article (PC Magazine, 24 Feb 1998):

(if the link doesn't work, search for NNTP Lotus Notes)

zumatic··on Windows93 SP2
IIRC for a while the Amiga calculator would crash the OS if you did that.
zumatic··on Chrome Won
This is what I came here to post, and you can see that, in the mobile chart, Chrome and Safari already seem to be levelling off. Maybe a better model would be like an ADSR (attack decay sustain release) envelope in sound synthesis where the logistic curve represents the attack / initial adoption phase, possibly followed by a mirror logistic curve representing mature saturation then eventual replacement by competitors. That said, some products do come back from the dead, like Mozilla itself; the Apple Mac is another example.

Saying "Chrome won" now feels like saying "IE won" in 2002 or so. Look at the chart here:

zumatic··on “A closure is a poor man’s object; an object is a poor man’s closure” (2003)
'Qc Na responded by hitting Anton with his stick, saying "When will you learn? Closures are a poor man's object." At that moment, Anton became enlightened.'

The cruel tutelage of Qc Na.

zumatic··on Umberto Eco's Anti-Library (2015)
A tip is essentially an LRU cache:

(I first heard about this concept ages ago, but that's the first article on Google; sorry if paywalled).

zumatic··on Brexit's Tech Brain Drain
Was anyone else reminded of John Harvey-Jones versus Morgan, where he bawled them out for pushing a car chassis up and down a hill several times as part of their production line?

Can't help thinking BMW might need to look at that anyway, regardless of Brexit.

zumatic··on Kristen Stewart co-authors AI paper
That was my initial reaction, but if you look at section 2, both paragraphs could plausibly have been written by Stewart and/or Shapiro; all the images are authored by Stewart as the director.
zumatic··on One Road Out of Depression
I am not a doctor, but I think if you have been clinically diagnosed as depressed, you can call yourself "Capital-D depressed" -- IMHO, obviously.
zumatic··on Electric Bikes Won Over China. Is the U.S. Next?
Interesting -- we could do with that in London. Is it all diesel cars? The article seems to say something about Euro IV -compliant maybe being OK?
zumatic··on Electric Bikes Won Over China. Is the U.S. Next?
Bans have been proposed in Holland from 2025 (http://www.dutchnews.nl/news/archives/2016/03/only-electric-...) and Norway (http://electrek.co/2016/06/03/norway-gasoline-powered-car-ba...), but it's very early days -- these are only kite-flying exercises, not serious attempts at legislation.
zumatic··on 78% of Reddit Threads with 1,000+ Comments Mention Nazis
...and what about words which contain the string "...nazi...", such as "Ashkenazim"? They don't seem to give the exact query, that I could see.
zumatic··on Bay Area Home Prices by Transit Stop
And here's one for London:

Note we tend to think of flats in terms of number of bedrooms. Hatton Cross is right next to Heathrow airport, if you're wondering why it is so cheap.

zumatic··on Why There Is No Hitchhiker’s Guide to Mathematics for Programmers
Agreed, but in your example 'xargs', 'curl' and 'print' are arguably meaningful.
zumatic··on Sort Faster with FPGAs
arguably it's O(N^2) in spacetime, because it's O(N) steps on O(N) hardware (N parallel units).

You can imagine different hardware architectures taking O(1) steps on O(N^2) parallel units or O(N^2) steps on O(1) unit(s), or anything in between.

""" The University of Manchester's Small-Scale Experimental Machine (SSEM)[15] is generally recognized as world's first electronic computer that ran a stored program—an event that occurred on 21 June 1948.[16][17] However the SSEM was not regarded as a full-fledged computer, but more a proof of concept predecessor to the Manchester Mark 1 computer, which was first put to research work in April 1949. On 6 May 1949 the EDSAC in Cambridge ran its first program, making it arguably "the first complete and fully operational regular electronic digital stored-program computer".[18] It is sometimes claimed that the IBM SSEC, operational in January 1948, was the first stored-program computer;[19] this claim is controversial, not least because of the hierarchical memory system of the SSEC, and because some aspects of its operations, like access to relays or tape drives, were determined by plugging.[20] """

zumatic··on Synth Secrets (1999–2004)
Worth dipping into even if you're not really into synths, because some of the anecdotes (like his quest for the GS1) are pretty funny.
zumatic··on APT tilting train: A laughing stock that changed the world
As well as the glitches, there's a story that the tilt was initially set to entirely cancel the lateral acceleration from the curve. The press on the demo train was well lubricated with free booze -- result: headlines about the new train making them sick.

A 6km radius would fit quite well with schemes like Community Radio in the UK:

...still need a licence, of course.

zumatic··on Writing an Operating System with Modula-3 (1995) [pdf]
It was very influential on Java (as the Java people acknowledged in their early documents) and C# (unsafe types).

[quote]And OMG the ridiculously verbose syntax.[/quote]

Not as bad as Ada, VHDL, Cobol etc.!

zumatic··on A Russian Family Was Isolated for 40 Years, Unaware of WWII (2013)
The climate varies greatly between different places on the same latitude. She seems to live near Abakan, Russia at about 53 deg. N; according to Wikipedia, this has average daily means ranging from -18.3 C to +20.0 C. Compare with Manchester, UK (53 deg 28'N): about +4.5 C to +16 C.
zumatic··on In J, functions have inverses (2012)
...and I should have said that you can replace the above by:

S \ R

zumatic··on In J, functions have inverses (2012)
This is also found in the Ruby hardware description language (not the same as the scripting language). A commonly-occurring pattern is:

R^~1 ; S ; R

where R and S are functions, ';' is composition ('.' in Haskell) and '^~1' is inverse. Usually this is for wiring (change order or grouping of wires to suit block S).

The wrinkle in Ruby is that R and S can be relations, not just functions, so data can flow both ways, just like actual hardware (can only flow from right to left in Haskell). Ruby won't try to guess the obverse function, unlike J.

zumatic··on Fred Dibnah – Steeplejack (1979) [video]
Yes! I'm glad someone else notices the similarities. Both suck-it-and-see northerners (though I think Martin comes from Grimsby, not Lancs.)
