I would like to hire Jonathan Sieber for the
summer.
He is currently in his Junior year in high school.
In high school, he has taken two
formal programming courses; one in Fortran and one in 1620 SPS.
He has also taken a course entitled
'Advanced Computing' at Columbia through the
Columbia University Science Honors Program.
In the Columbia course, he
had compiler optimization techniques and some
practical 360 programming.

He is a member of the Explorer Scout Troop that meets
monday nights at the Labs.
After troop meetings, the scouts 'work' on various
computers around the Labs.
Last year Sieber worked on the Honeywell 516 using FOCAL,
a Basic-like language.
During the summer and this year,
he has worked on the UNIX PDP-11/45.
He knows PDP-11 machine language and he
knows how to use the UNIX subsystem software.
(Editor, Debugger, Assembler and various languages)

I have worked closely with him and believe that
the summer job will help him and also benefit the Labs.
He is capable of STA work with the added advantage that
he is already fleuent in the use of the PDP-11 and the UNIX
time sharing system.
If he is hired, he would work with Dennis Ritchie and
myself on UNIX
and its associated software.
The following is a list of pending projects that
he is capable of doing:

.ti 5
Subsystem conversion to C
.ti 5
UNIX Manual updating
.ti 5
Driver for photo typesetter
.ti 5
APL runtime
.ti 5
Finish new chess program

His previous work
includes a program to determine student
rank for Dayton's Guidance office;
modifications to IBM's 1620 DOS to allow
the addition of non disk oriented compilers;
a combinatorial program to find a
maximal solution to a cross word puzzle;
an FSNAP to Fortran sieve;
and an FSNAP compiler.
The latter three programs were written on
the PDP 11/45.
