Mirroring a website using wget

Every time I have to restore from my memory and man the same line of making a local copy of a website (or a part of it). But enough of that! I'll just post the line here and will never forget as long as this blog is not taken down (which may happen at some point, but who knows when and why?)

wget -N -np -r -l0 -k -p <URL>

wget -N -r -l0 -k -p -D website.edu,img.website.edu http://website.edu/stuffdir/ -I stuffdir  -H

Also, this fine man explains how to fix the tilde character converted to a hex value: http://www.kozubik.com/docs/wget_hack.txt (tldr: urlchr_table:url.c). Weird that the source Ubuntu version has it fixed while the binary package doesn't.

LoL

Finding a working version of LoL (the only sane keyboard navigation plugin for Firefox to my knowledge) is getting more and more difficult every time I have to install a new instance of Firefox, so here is the link:

Fixing the "stack overflow in regexp matcher" error in Emacs.

I'm using a relatively large ctags file (~20 Mb) built for a C project I'm working on and I ran into the problem recently that the complete-symbol command (Ctrl-Alt-i) that auto-completes function and variable names in C files fails with the "stack overflow in regexp matcher" error.
Long story short, you need to increase the re_max_failures variable located in regex.c to fix this. Is this the right way? I don't know, but it works for me and the comments were not very clear to elaborate. There is also some "smart" logic related to re_max_failures in emacs.c that apparently tries to tweak it to the best value possible, but it turns out to be not smart enough for my use case.

    best_roll = ()
    best_avg = getPrize(before)

    for roll in (range(1,9), range(4,8)):
        avg = 0.
        for i in roll:
            avg += getRoll(before + i)[1]
        avg /= float(len(roll))
        if avg > best_avg:
            best_avg = avg
            best_roll = roll
    return (best_roll, best_avg)

for before in range(20):
    roll=getRoll(before)
    print("%d: %s(%f)" % (before, str(roll[0]), roll[1]))

Which leaves us with the following table of the best bets:

current sum: best choice option (average money won)

Adjusting console column width number in R.

options(width=Sys.getenv("COLUMNS"))

(as seen on http://www.mail-archive.com/r-help@r-project.org/msg78788.html)

It may be put in ~/.Rprofile to initialize during startup, but the Squeeze version (2.11.1) seems to be bugged out and does not work. My attempt in being a smartass

options(width = system("echo $COLUMNS", intern = TRUE))

does not work either.

Finding kanji I haven't studied yet in my main deck
