I bought a CD-ROM, The World of Patterns<\/a>. It\u2019s supposed to work on \u2018Any computer with an Internet browser and a CD-ROM drive\u2019<\/i>. Guess I don\u2019t just have any computer, then \u2026<\/p>\n

The disk \u2014 an interesting mathematical\/artistic study of patterns \u2014 is arranged as a tree of HTML files, with internal links and images. This is how the folders appear on my computer:<\/p>\n

All neatly lower case, as one might expect. Unfortunately, the internal links are hard-coded to access links such as \/art\/I<\/span>slam\/over.htm<\/em>, and Linux, being good and literal, can’t find the upper case ones.<\/p>\n
Unfortunately, the majority of computers quietly ignore the case of letters on removable media. Linux’s insistence on being correct is at odds with what is generally considered useful. But there’s a way around this. You can give the mount command options to tell it to be more chill about case:<\/p>\n
sudo mount -t iso9660 -o loop,check=relaxed,map=normal,norock,nojoliet disk.iso \/mnt\/scratch\/<\/pre>\n
This works for me quite well:<\/p>\n

The CD-ROM is interesting, if a little dated. The author has gone on to produce the website tilingsearch.org<\/a>, a huge database of historical tile patterns.<\/p>\n","protected":false},"excerpt":{"rendered":"
