- Khan exercises
- Khan Academy has created a generic framework for building exercises. This framework, together with the exercises themselves, can be used completely independently of the Khan Academy application.
The framework exists in two components:
- An HTML markup for specifying exercises.
- A jQuery plugin for generating a usable, interactive, exercise from the HTML markup.
Using the Framework Locally
You need to serve the files from some sort of a server. You can't just open the files directly in a browser. For example:
cd khan-exercises python -m SimpleHTTPServer
or
cd khan-exercises python3 -m http.server
Now if you open your browser to `http://localhost:8000` (or `http://127.0.0.1:8000/`) you should see the contents of the `khan-exercises` directory. Navigate to the `exercises` subfolder, and an HTML file under there to see an exercise.
Writing Exercises
The process for writing exercises is rather well documented. More information about this process can be found in the Khan Exercises wiki. Specifically:
- KidsRuby
- Have fun and make games, or hack your homework using Ruby! Just tell your parents or teachers you're learning Ruby programming... ;)
- Learning Perl the Hard Way
- a book for people who already know how to program in another language, but don't know Perl.
- Libcsdbg
- Libcsdbg is a C++ exception stack tracer. When an exception is thrown, caught and handled, libcsdbg offers the tools to create and process the exception stack trace, the path the exception has propagated up the call stack, unwinding it, up to the section were it was handled. The traces are detailed with demangled function signatures and additional addr2line info (the source code file and line that each function was called). Libcsdbg will perform flawlessly with single and multi-threaded (or multi-process) programs, with any dynamically linked shared object (DSO - Dynamic Shared Object) and with any statically linked library. Additionally, libcsdbg helps the developer/tester create sophisticated stack traces of any thread, at any given moment during a process execution, as a snapshot of the runtime call graph. This is very useful in cases of fatal errors, reception of terminating signals or process abortion/termination (such as segmentation faults). libcsdbg can use all the well-known objective code file formats (a.out, elf, coff, ecoff, etc.) and can easily be used as the base for your own instrumentation code. libcsdbg transparently loads the symbol tables of the chosen dynamic libraries and of the executable, demangles function symbols to complete signatures, and binds function names to runtime addresses (even for the DSO symbols).
- Librsb
- librsb is a library for sparse matrix computations featuring the Recursive Sparse Blocks (RSB) matrix format. This format allows cache efficient and multi-threaded (that is, shared memory parallel) operations on large sparse matrices. The most common operations necessary to iterative solvers are available, e.g.: matrix-vector multiplication, triangular solution, rows/columns scaling, diagonal extraction / setting, blocks extraction, norm computation, formats conversion. The RSB format is especially well suited for symmetric and transposed multiplication variants. On these variants, librsb has been found to be faster than Intel MKL's implementation for CSR. Most numerical kernels code is auto generated, and the supported numerical types can be chosen by the user at build time. librsb implements the Sparse BLAS standard, as specified in the BLAS Forum documents.
- Little Wizard
- Little Wizard is a development environment for children. It is intended to be used by primary school children to learn about the main elements of real computer languages.

MDK includes a MIXAL assembler (mixasm) and a MIX virtual machine (mixvm) with a command line interface. In addition, a GTK+ GUI to mixvm, called gmixvm, and a Guile interpreter with an embedded MIX virtual machine called mixguile, are provided. It also contains an Emacs major mode for MIXAL programming and an elisp program allowing to run the MIX virtual machine in one buffer while viewing the MIXAL source code in another.

- Oxref
- Oxref generates a cross reference listing of symbols defined in non-stripped object files and/or libraries. A cross reference listing shows the functions using certain symbols (functions, data). This is useful information during program develop- ment and debugging phases. E.g., assuming that the signature; the pre-conditions or the post-conditions of a function must be changed it is important to know from what function(s) the function-to-modify is called to verify that the changes to the modified function do not break its calling functions. The generated cross reference listing starts with a header showing information about the program, a time stamp and the arguments passed to oxref. E.g., To create the program from its sources, either descend into the oxref directory, or unpack a created archive, cd into its top-level directory and follow the instructions provided in the INSTALL file found there. Alternatively, binary ready-to-install versions of oxref are available in verious GNU/Linux distributions, in particular Debian. See, e.g., https://packages.debian.org/search?keywords=oxref&searchon=names&suite=all§ion=all Github's web-pages for oxref are here: https://fbb-git.gitlab.io/oxref/

SNAP! is presented by the University of California at Berkeley. It was developed by Jens Mönig at MioSoft Corporation, with design input and documentation by Brian Harvey at Berkeley, and contributions by students at Berkeley and elsewhere.

The TinyCNC-II unit helps with the monotonous repetitive operations found in using a lathe or milling machine with accuracies of 0.001 inches to a distance of 99.999 inches for any single move for Imperial units and 0.01 mm to a distance of 999.99 mm for any single move for Metric units. The X, Y and Z axis’s are user selectable as one of the three types of Imperial or Metric selections. The fourth Axis (A) is dedicated as a degrees axis with accuracies of 0.01 degrees for up to 999.99 degrees of rotation for any single move. The TinyCNC-II provides the user with several useful control types. These are Simple for ease of use, Advanced for complex moves, Remote for control from another unit and Hole modes for creation of hole patterns.

- ZerSol
- The purpose of the ZerSol C++ library is the finding all the zeros of an analytic function that are contained in a given rectangular region of a complex plane. It is based on the argument principle and recursive subdivisions of the region coupled with the Newton's iterations at the final stage of the search. The ZerSol library assumes that evaluation of the function is expensive and tries to minimize the number of the function calls by using efficient algorithms and special data structures. Although easy to use, the library provides an extensive set of interface functions for the search customization and detailed diagnostic messages in case of failures. It is supplied with a set of test cases and bindings for C and Fortran users. The library is thoroughly tested on many hard problems and demonstrates a good performance.
