PhD in Comp Sci from Univ of Washington, designing and writing code for my own outfits since then. Currently back at alma mater writing code for pervasive computing research projects. I'm still interested in running OCaml on iOS. I also enjoy taking long walks on cloudy days.

jeffsco··on Lorinda Cherry, author of dc, bc, eqn has died
I use bc a hundred times a day, it's invaluable. Thank you; RIP
jeffsco··on The “high-level CPU” challenge (2008)
I loved this (paraphrased) quote:

To quote Ken Thompson (from memory) – "Lisp is not a special enough language to warrant a hardware implementation. The PDP-10 is a great Lisp machine. The PDP-11 is a great Lisp machine. I told these guys, you're crazy."

jeffsco··on Bloomberg/bucklescript: A back end for the OCaml compiler which emits JavaScript
What happens if you declare an external function of type 'a -> 'b? Obj.magic is trivial to implement, it's just the typing that is wonky. (Disclaimer: I have never looked at BuckleScript or js_of_ocaml.)
jeffsco··on How I Deal with Harassment, Abuse, and Crazies in General
(You noticed. It is a form of humor fwiw.)
jeffsco··on Generation Anthropocene: How humans have altered the planet for ever
This seems similar to saying to a drowning person, "I don't see how water is a bad thing."
jeffsco··on Doing Mathematics Differently
Obviously nobody is forcing you to read it. Perhaps it's written for an English speaking audience that doesn't mind skipping over some French here and there.
jeffsco··on Watson for President
Rather than simply asserting that the variable speed limits are a complete failure, it might be nice to cite some measurements. I live in Seattle, and I find the variable limits to be useful information.
jeffsco··on The strange non-transitivity of random variables (2014)
Imagine a tournament to choose the best tennis player. If you imagine these dice as a simple model of a tennis player, there can be no best tennis player. So tennis tournaments make no sense. This is paradoxical if you believe in tennis rankings.
jeffsco··on There are no rules in math
I was taught the "New Math" as a child and did not hate it. It was wonderful. When I look at math blogs today, they use notation and terminology I learned back then. This is a tremendous advantage (or so it seems to me).
jeffsco··on Some Musings on Mathematics
The thing you realized is also what the guy is arguing is not the case. There's no one right view, but that's the point of his argument.
jeffsco··on Feynman's concept of scientific integrity
Repute is what people think of you in the aggregate. It doesn't make sense (at least to me) to say "beyond repute." On the other hand to say that something is "beyond reproach" is a standard phrase indicating that no reasonable person can find anything to disapprove about the thing. Perhaps you're thinking of "beyond dispute."
jeffsco··on A Garbage Collector for C and C++
Please cite some evidence. As a GC fan, I'm interested in this question. (In my opinion, GC is more than worth the cost.)
jeffsco··on Caesars: A private equity gamble in Vegas gone wrong
From the article:

    By the time the deal was about to close, Loveman
    remembers that it was “a bit uncertain” as to whether
    every bank would honor its commitment. But they did.
jeffsco··on A wave of experiments is probing the root of quantum weirdness
I am biased as a Scott A. fan and as somebody who knows essentially nothing about QM. However I see no way to conclude that Anderson and Brady even know what they're talking about, much less that they win the debate on the linked Scott Aaronson page. I just read through it again to confirm my recollection (skipping the Motl and Sidles posts fwiw).
jeffsco··on I Hate the News (2006)
"I cannot help counting it a fault in him that he had no ambition. ...Instead of engineering for all America, he was the captain of a huckleberry party," Emerson lamented in his eulogy of Thoreau.
jeffsco··on Mac Apps That Use Garbage Collection Must Move to ARC
What Apple calls "automatic reference counting" is what is usually known as just "reference counting." They call it "automatic" to distinguish it from the previous, even cruder, system where counts were manipulated directly by the programmer. Obviously this is an improvement, but personally I am a supporter of GC. It is a myth that reference counting is not subject to arbitrary pauses: http://www.hboehm.info/gc/myths.ps
jeffsco··on What kind of funny is Kafka?
I find Rivka Galchen's essays enthralling. One intriguing thing she wrote a while back is that the game Minecraft has a Joycean quality. I don't know what she means by this, but I'm pretty sure she's correct.

jeffsco··on Why Golfers Buy Hole In One Insurance
The premise seems false. The insurance is against the cost, as is usual.
jeffsco··on Show HN: Unicode glitch art iOS app
http://eeemo.net is one.
jeffsco··on US immigration didn't allow us to build a team here, so we built one in Colombia
The title says a team, suggesting that you can't build any team at all in US. But the evidence presented shows that he couldn't build a specific team: there exists a team he couldn't build in US.
