Once upon a time, the world wide web was cool. More importantly it was useful. You’d hop onto Google and search for something like “apache installation HOW-to”, “vector spaces”, or “how to build a compiler” and find well written informative documents and essays written by individual authors. Now the web feels like the intersection of the set of all top 10 lists.

Thus, this page will be a collection of links that I find interesting and/or useful.

Individual Person Sites

  • Markus Wandel - He’s an engineer with other hobbies. The website hasn’t been updated since 2009, but it’s still worth looking at. I found this guy’s site over 10 years ago. The first page I read was about his homemade PBX (which I recommend reading).
  • Geoff Wozniak - A small but interesting programmer’s blog.
  • null program: Chris Wellons - This blog belongs to a programmer and is all about programming. His posts are technical and interesting with C being a favorite topic of his.
  • Paul Hsieh - This is an older site that’s no longer updated but still worth looking at; especially if you’re interested in assembly programming.
  • Viktor T. Toth - A career programmer who’s life passion is physics.

  • Advice for amateur mathematicians on writing and publishing papers - From the source: There’s no reason why amateurs can’t make worthwhile research contributions in mathematics. It has happened many times in the past, and I know of several cases today. I don’t have time to offer a lot of personal advice and guidance, but I figured I’d post some general advice here. I’ve aimed it at people who think they’ve already solved famous problems, since those are the sort that typically write, but it should be equally useful for people with more modest aspirations. I focus on the mechanics of how to do literature searches, write papers, and publish them, because I have less to say about the deeper issue of how to do research. None of this advice is specific to amateurs, but professionals already learn all these things from their advisors.
  • Open Problem Garden - A collection of open (unsolved) problems in mathematics.
  • Purdue’s Problem of the Week - Weekly math problems to solve.


  • SuRuSu - A flash card replacement similar to Anki.
  • UPC Database - A crowd sourced database of UPC (and more) barcodes.

World Affairs
