Project ideas

This is a selection of big / hard / interesting projects from my TODO list.

GCC

• GCC code injection on breakpoint conditions and action
• GCC as a library-based syntax highlight
• add identifier hyperlink capabilities to GitLab like lxr.free-electrons.com isaacs/github#292

QEMU

Use QEMU to test an OS with assertions, like Selenium for browsers

Small

• https://en.wikipedia.org/wiki/Poincar%C3%A9_disk_model in JavaScript

  Possibilities:

  • draw circles around the mouse
  • straight lines that cross two points: http://demonstrations.wolfram.com/TrianglesInThePoincareDisk/ Could also show distance.
  • really slow but great demo: http://jsxgraph.uni-bayreuth.de/wiki/index.php/Poincare_disc_model

  Maybe: https://github.com/cirosantilli/hyperbolic-canvas

• https://en.wikipedia.org/wiki/Real_projective_plane in JavaScript

  Show it on a flat circle.

GDB

• https://sourceware.org/bugzilla/show_bug.cgi?id=13984#add_comment

• GDB feature requests:

  • disassemble with binutils as a library

  • gdb up arrow history bug

  • gdb python continue until a breakpoint that prints only exactly what I tell it to.

  • rbreak full path, resolve path e.g. ./a.c

  • rbreak Regex for file to break in directory

  • List all symbols

  • Python get instruction memory from disassemble without an extra read

  • Python breakpoint without message. internal has other side effects like not being able to list it.

  patches:

  • add if to call
  • compiled break condition
  • compiled break action
  • http://www.gnu.org/prep/maintain/maintain.html#Legal-Matters in GDB contribute update link

Hardware

plug and play

Understand everything that happens between plugging in an USB and seeing /dev/sdb appear.

Stack Overflow statistics

How to do statistics on ratios:

• high reputation / total posts
• high profile views / reputation

But consider users who have say, one post with a ton of upvotes as not significative.
