    The high-performance and featureful Quil simulator.

    and/or in-line assembly code, and still can't optimize specific matrix shapes and structures, or do algebraic simplifications to eliminate work altogether.

    The regex library FTA is a great, and clean, example of a long standing practice of compiling regexen, except it doesn't use any fancy VMs or any fancy JITs, just "when you see this regex, automatically turn it into this Common Lisp code, and let the Lisp compiler handle the rest."




  • RE2

    RE2 is a fast, safe, thread-friendly alternative to backtracking regular expression engines like those used in PCRE, Perl, and Python. It is a C++ library.

    As this is a regex->DFA implementation I wonder how it compares to Google RE2 [1]

    there are nice performance comparisons to backtracking engines (like pcre), but re2 was missing from that list. speaking of cl-pcre: are there common lisp bindings to re2?


  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.
