lharri73 / LLib

A collection of tools and libraries I've created to make life easier. Mostly, these binaries/libraries save me a few copy-paste actions, but those take time (arguably less time than it took to put these together).

Landon's Library of Things

This is a small collection of tools that I've written to make life easy. Mosltly, just to solve small problems or perform silly little tasks that are otherwise tedious.

Installation

This requires cmake...and that's it.

1. Run cmake .
2. Add the bin folder to PATH
3. Add lib to LD_LIBRARY_PATH

Libraries and Programs

• sping

  • Search through an ssh config and ping the hostname of the provided host

• libMOA

  • Sometimes the rand library isn't all that random...This provides a more random number generator that generates various random types.
  • Originally sourced from http://www.agner.org/random/

• calc

  • a command line calculator. Honors order of operations and parenthetical expressions.

• con

  • a command line conversion utility. Converts the input unit to the specified output unit. Units can be customized in units.txt. This works by building a graph of valid conversion, then performing dijkstras to find the path that requires the least number of conversions to reach the desired unit. The conversion path is printed as well as the converted value.

• mvdl

  • Moves the most recently modified file in your downloads folder to the currnet location of the shell. Takes no arguments. That is all.

• libCUDSafe

  • Provides a protected interface to the CUDA C++ host and device calls.
  • Implements the following Host functions (on failure, each prints the CUDA error string and which file and line the error occurred in.):
    • safeCudaMalloc: allocate memory and throws runtime error on failure
    • safeCudaMemcpy2Device: copy host memory to device memory.
    • safeCudaMemcpy2Host: copy device memory back to host. ""
    • safeCudaMemset: Memset, but for device memory.
    • safeCudaFree: Like Free, but throws a runtime error
  • Implements the following Device functions (on failure, each prints the value to test against, and the value provided). The assertions insert a bad assembly instruction to halt execution within the device kernel so you don't get thousands of lines of garbage from a single error.
    • CUDA_ASSERT_NEG: raise an exception if a value is not negative
    • CUDA_ASSERT_NEG_E: raise an exception if a value is not negative or equal to 0
    • CUDA_ASSERT_POS: raise an exception if a value is not positive
    • CUDA_ASSERT_POS_E: raise an exception if a value is not positive or equal to 0
    • CUDA_ASSERT_GT: raise an exception if the test value is not greater than set value
    • CUDA_ASSERT_GT_E: raise an exception if the test value is not greater or equal to the set value
    • CUDA_ASSERT_LT: raise an exception if the test value is not less than set value
    • CUDA_ASSERT_LT_E: raise an exception if the test value is not less or equal to the set value

TODO

- random word generator
- random number generator (program)
- python array to matlab (and back)
