Eliminated the need for the `.tar.tstamp` files. It became intractable
to produce a tarball that was byte-for-byte identical to a tarball
on another platform. We further simplified the process used by the
`bin/tar-year.sh` tool to no longer need `.tar.tstamp` files.
Removed `.tar.tstamp` files and updated the manifest.
Sorry (tm Canada 🇨🇦) for the "flip-flop".
The `bin/tar-year.sh` tool now uses a similar algorithm to how
`bin/tar-entry.sh` determines if a compressed tarball needs to be
rebuilt.
Changed `bin/tar-entry.sh` VERSION from "1.3.3 2024-03-27"
to "1.3.4 2024-03-27".
Changed `bin/tar-year.sh` VERSION from "1.1.3 2024-03-27"
to "1.2 2024-03-27".
Performed `make www` and `make form_entry_tarball`
and `make form_year_tarball` to complete the above
actions and test these changes under macOS.
TODO: Test the `bin/tar-year.sh` tool under Linux.
TODO: Address issues with building the top level `ioccc.tar.bz2`
and the `bin/tar-all.sh` tool and the `make form_all_tarball` rule.
NOTE: The `bin/tar-all.sh` tool and the `make form_all_tarball` rule
and the `make tar` should **NOT** be used at this time.
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.
