I received the bound copies of my dissertation yesterday. They look nice, but they’re kind of thin, for so much work. Including front matter, there are 157 pages.
Some more numbers: The source code for my dissertation project has 35,979 lines with 136,951 words. At 30 lines per page, that would be 1,200 pages; but source code lines rarely fill the whole width of the page. At 250 words per page, that would be 548 pages; but wordsInProgramsAreOftenVeryLong.
It’s somewhere in between. But it’s also been written over the course of seven years.
