There should be Artificial Intelligence / Computer Vision techniques and software to decide whether a photo needs to be rotated portrait instead of landscape. It would be easy to come up with training data.

Also, instruct the browser to rotate a source image via <IMG ROTATE="...">, and point and click.
Imagine a highly ruggedized portable computer sitting in gel mounted in a crystal ball. Input is not via keyboard, but one or more cameras inside the ball which measure movement; that is, you "type" into the ball by waving your hands around it (the traditional way of communicating with a crystal ball, right?). The internal display need not be rectangular: it could be spherical or a bunch or displays on some of the faces of a polyhedron (try truncated cube). Power can be via induction (like an electric toothbruch), photovolatic, or vibration (magic 8 ball!).

Much havoc could be wrought by factoring this number. As expected, gp repeats ellfact for a long time. Let's try to find a smooth factorization of a number in the neighborhood, or vicinity of a multiple.
? nextprime(m)-m %6 = 1032 ? precprime(m)-m %7 = -398 ? for(i=m-100,m+100,print(i-m," ",factorint(i,15)))

The unix crypt function takes a mysterious salt parameter, used to thwart giant precomputed dictionaries translating from common words to straight hashes.
In default mode, only the first two characters of the salt are significant, and they are chosen from the 64-character set [A-Za-z0-9/.] (or "slashdot"). Only the first 8 characters are significant in the DES based password generator.
However, if the first three characters are "$1$" then the next eight characters (all bits significant, except the salt gets truncated before the first dollar sign) are the salt to a MD5 hash, which allows passwords of unlimited length.
Here is some messy perl code from within a shell script. Perhaps though the salt should be chosen through rand() as suggested in perldoc -f crypt.
read -s password
secr=`perl -we "print crypt(q($password), qq(\x24) . q(1) .
qq(\x24) . q($salt)), qq(\n);"`;
Hopefully a SHA-256 (etc) based hash can be standardized soon.
If you are downloading a file, e.g. openoffice, it is easier to use bittorrent rather than try to figure out to which mirror you will have the highest bandwidth (essentially, use all of them, assuming a bt client runs on each mirror).
jj2000 is partially included in JDK 1.5 (jai_imageio.jar) but not the CmdLnEncoder or CmdLnDecoder. When using the downloaded jar file:
Exception in thread "main" java.lang.SecurityException: sealing violation: package jj2000.j2k.util is sealed
because of collisions in the namespace. (And also weird stuff like substituting java.awt.Point for jj2000.j2k.image.Coord)
To change the namespace:
find . -type f -name '*.java' -exec perl -plwi"" -e 's/jj2000\./jjsipboutland2000./g' '{}' \;
(need to rename the in the jj2000 directory in src/ as well)
Here is a patch to get rid of the enum keyword/identifier problem.
Finally, to compile:
javac -g -encoding ISO8859-1 -cp `pwd` JJ2KEncoder.java
and JJ2KDecoder
Or leach off of AFS:

for what combinations of mass and rotational speed is gravity sufficient to hold a neutron star together? On the other extreme, can high rotational speed prevent collapse into a black hole, or is is only a function of mass?

How near would a major event such as two black holes coalescing need to be for the gravitational waves to cause harm to Earth? What would the damage be? Could long-term exposure cause climatic change?
Both AFS volume location servers (dig -t afsdb csail.mit.edu) and Kerberos KDC's (dig -t srv _kerberos._udp.csail.mit.edu) are available through DNS; however you may need to supply your client software with the domain-realm mapping csail.mit.edu = CSAIL.MIT.EDU (needed for modified knoppix and windows leash)
There are at least three versions of xemacs out there for windows: xemacs "cygwin" and xemacs "native" from xemacs.org (I think they differ on how pathnames are represented in C-x C-f and what shell is invoked in M-x shell). Despite it's name xemacs.org "cygwin" appears to use windows native windows.
The thrid is xemacs "cyg-X" from cygwin, which uses cygwin's X to draw the windows, and therefore cannot be straightforwardly launched from the windows start menu (though there probably is a way).
xemacs for windows is stuck at 21.4.13 "rational fortran" 2.5 years old
Let each node have only a finite amount of storage and connections to other nodes. What model of computation satisfies this? There is a boundary: whether a node has enough space to even address any other node.
VAX/VMS could grant a user READALL privilege, allowing the ability to read anything on the filesystem, but not write. As the Un*x root user, you get cannot decouple read and write.

CD's can spin only so fast before they distort or shatter. However, the reader head can spin the other direction, and since it doesn't have to be made of plastic, it's not limited in speed that way.
What is the gravitational binding energy of the earth? Other binding energies? How large would a Death Star have to be to destroy the earth in one second, using chemical energy? fusion energy? antimatter?
What is the volume of neutronium antimatter equal to the binding energy?
Would Russia be a happier place now if they had allowed personal liberties (e.g., speech, jury trial, press) but kept a centrally planned economy? Is it possible?
