Here is a more flexible functional representation of numerals, courtesy Steensgaard-Madsen [1989], but written in Fexl: \zero = (\zero\succ zero) \succ = (\n \zero\succ succ n) This delays the binding of the handler functions (zero

So let me see if I follow the definition of append there, using Fexl notation which doesn't use pattern matching (all data items such as lists are just functions applied normally). Here's the fold function: \fold = (\func\val\list list

One minor issue, I think. I noticed on page 7 it says: bcrypt(cost, salt, pwd) state <= EksBlowfishSetup(cost, salt, key) I guess the symbols "pwd" and "key" are synonyms there, right?

These are my favorite: http://bullion.nwtmint.com/gold_krugerrand.php Krugerrands have the lowest premiums and are resistant to scratching. That particular vendor is highly professional.

Asimov said it well: "violence is the last refuge of the incompetent." The people who stole that man's money are incapable of earning a living through voluntary means, so their first instinct is to reach for a gun. I steer clear of peop

MUCH faster, thanks. Now I'm piping that into Perl to convert the counts to percentages. If I figure out a one-liner for that I'll let you know. Next I'll be tempted to write a module for generating "realistic" (Benford-compliant) random n

Right Fred. Khan could have responded maturely, either answering your questions or acknowledging that he doesn't yet know the answers. Feynman probably would have said something like "good point Fred, those are exactly the kinds of questi

Heh, same thing happened to me when I downloaded Thunderbird 3.0 to my Linux machine. I didn't know what to do next, and I searched the web in a bewildered fashion. Then I sent a Pidgin message to a colleague and he said "you don't instal

I had to use a different stat command on my Linux system. This worked for me: find . -type f -exec stat -c %s {} \; | cut -c 1 | sort | uniq -c Note that I exclude directories to avoid the size 4096 bias. I ran it in my "project" directory

That is precisely why I criticize SSL. One of the primary goals of SSL is to authenticate a site so that Grandma can rest assured she is not being scammed. "Phishing" represents a catastrophically expensive failure to achieve that goal.

I welcome your suggestions on how browsers can help protect Grandma from the phishing on the computer she already uses. Using someone else's computer for secure access is always problematic, for reasons far deeper than we're discussing. I

Interesting observations. How then would you suggest improving security against phishing? For example Grandma gets an email saying "You have initiated a large wire transfer from your Building and Loan account. Please log in to confirm th

That's a great concept which I need to try. The challenge will be extending it to SSL and making it friendly to Grandma. That said, when Grandma first signed up at building-and-loan.com, she probably went to the correct site. Now that she

Yes, it's pretty close. However where SSH warns you whenever you encounter a new server, the SSL in your browser only warns you when you encounter a new CA (Certificate Authority). For the browser to behave more like SSH, it would have to

SSL is a messed up protocol, relying on trust in central authorities. SSH did it right: it only ensures that the server you connect with today is the same one you connected with yesterday, and it does not aim to do anything more. An SSL c

The disincentive to work is very real indeed, I can assure you. I am making the best money of my life and I aim to make less. That extra money is costing me time spent on more rewarding pursuits such as writing interesting code, or even j

However, when building functions with combinators it's clearer to use bound lambdas along the way: \I = (S C C) \U = (S I I) \R = (S (C S) C) \Q = (S R (C U)) \Y = (S Q Q)

I might prefer this: S S I (S (S (C S) C) (C (S I I))) But then I'd be tempted to abstract the I out and apply to (S C C).

It is true that script kiddies write ugly and unreadable Perl code. It is also true that professionals write highly disciplined and beautiful Perl code. Incidentally, on the subject of object orientation, I concur with Sriram Srinivasan's
