bash parameter substitution quick reference

I can never remember the syntax for all the various substitution possibilities in bash. Though many places detail them all (e.g. man bash, Advanced Bash Scripting Guide), the syntax is threaded through paragraphs of text. Here is my distilled quick reference.

Many thanks to snipt for housing this and the many other miscellaneous code snippets I can never keep in my head but constantly need.

Candidacy!

This past Monday I finally made candidacy in my graduate program.

Announcing the ESIO library

I've just publicly released a scientific library called ESIO used to generate the results I've recently presented.  ESIO has been used broadly within my research group and I consider it production-ready. 

ESIO simplifies getting high throughput input and output of structured data sets using parallel HDF5. The library is written in C99 and may be used by C89 or C++ applications. A Fortran API built atop the F2003 standard ISO_C_BINDING is also available.  ESIO is LGPL software and is available from https://red.ices.utexas.edu/projects/esio/wiki.

In particular, ESIO provides:

• Distributed IO of 1D lines, 2D planes, and 3D fields of data
• Support for scalar-, complex-, and vector-valued data
• Single and double precision floating point storage
• A mechanism for storing both string and numeric metadata
• Support for contiguous and strided in-memory data
• Support to simplify writing restart file sequences
• A handy esio_bench utility for performance benchmarking
• A comprehensive regression suite

I am long, long overdue on creating a paper introducing ESIO.
