Updated 1337 hacker rulz to version 7. Added `1337.mk` to contain the updated 1337 hacker rulz (v7). We use an optional include of `1337.mk` (or `../1337.mk`, or `../../1337.mk`) to include the 1337 hacker rulz. Changed `make deep_magic` to `make more_magic`. Changed `bin/tar-entry.sh` VERSION from "1.3.7 2024-07-22" to "1.3.8 2024-07-23". Changed `bin/tar-year.sh` VERSION from "1.2.5 2024-07-22" to "1.2.6 2024-07-23". Add `make new_entry` to `YYYY/Makefile` and `template/Makefile.year`. Change `make new_year` to use `sort -n -u`. Made minor debug message fixes to `bin/new-year.sh`. Changed `bin/new-year.sh` VERSION from "1.3 2024-07-23" to "1.3.1 2024-07-23". Improved `bin/add-dir.sh` to update `YYYY/Makefile` with the new entry directory name. Changed `bin/add-dir.sh` VERSION from "1.0 2024-07-21" to "1.1 2024-07-23". Performed `make www` to accomplish the above and to test under macOS.
To build:
make
To use:
./hoyle point ...
Try:
./try.sh
Judges' remarks:
The obfuscation functions at several levels. Note the clever
use of use of #defines. The #define do(if,else), for example,
is delightful. The code itself contains a bunch of curves
designed to throw you off axis. :-)
Author's remarks:
This application graphs polynomials on a standard Cartesian coordinate system.
Polynomials of the form ax^0 + bx^1 + cx^2 + ... are graphed by passing the
coefficients a, b, c, etc. as double precision arguments. It allows up to
8 parameters (thus up to x^7).
Points of interest:
- the x axis goes from
-32to+31. - the y axis auto scales!
- up to 8 coefficients may be passed in.
- the graph will determine direction and use slashes and
dashes rather than a simple block of
Xs.
For example, to graph y = x^2:
./hoyle 0 0 1
Note that:
./hoyle 0 0 2
will produce the same graph, since the y-axis is auto scaling.
