the flattening

not to be confused with the Minecraft technical update

I'm moving about the pages to be have a more flat, less nested structure.
I feel like that'll improve URLs a lot, making them more readable than ever.

over the years I've learned that flatter is better, and that tagging is generally a much more effective way of organising things.
this doesn't get rid of categories entirely, as I think having the category makes the URL much a bit more readable in the end.
my current vision does include a concept of "major categories" either way.

+- one thing I realised while reading some code at work that worked with C strings: it's surprising how easy it is to match a prefix on a C string.
+
+```c
+if (s != NULL
+    && s[0] == 'h'
+    && s[1] == 'u'
+    && s[2] == 'g')
+{
+    // ...
+}
+```
+
+% id = "01JCGAM5537WYE3GEN6WGX8WD0"
+- this works because of the NUL terminator---if it appears at any point in the string, the `s[i] == c` comparison will return `false`, thus breaking the `&&` chain---so indices always stay in-bounds!
