Avoid relying on compiled modules too much. Even if it is Free,
compiled code makes packages more expensive to audit, build,
distribute and verify. public-inbox itself will only be implemented
-in scripting languages (currently Perl 5).
+in scripting languages (currently Perl 5) and optional JIT-compiled C
+(via Inline::C)
+
+Do not recurse on user-supplied data. Neither Perl or C handle
+deep recursion gracefully. See lib/PublicInbox/SearchThread.pm
+and lib/PublicInbox/MsgIter.pm for examples of non-recursive
+alternatives to previously-recursive algorithms.
Performance should be reasonably good for server administrators, too,
and we will sacrifice features to achieve predictable performance.
See design_www.txt and design_notes.txt in the Documentation/
directory for design decisions made during development.
-For now, one may optionally subscribe to the mailing list by
-sending an email to: meta+subscribe@public-inbox.org
-(and confirming). However, reading over the mailing list is
-the least reliable method of reading a public-inbox.
+Perl notes
+----------
+
+* \w, \s, \d character classes all match Unicode characters;
+ so write out class ranges (e.g "[0-9]") if you only intend to
+ match ASCII. Do not use the "/a" (ASCII) modifier, that requires
+ Perl 5.14 and we're only depending on 5.10.1 at the moment.
