Fold conv package into fmt Both packages had nearly identical dependency requirements, so merging them should help reduce the complexity of the build graph.

Add x86_64-linux-gnu emulator I wanted a tiny scriptable meltdown proof way to run userspace programs and visualize how program execution impacts memory. It helps to explain how things like Actually Portable Executable works. It can show you how the GCC generated code is going about manipulating matrices and more. I didn't feel fully comfortable with Qemu and Bochs because I'm not smart enough to understand them. I wanted something like gVisor but with much stronger levels of assurances. I wanted a single binary that'll run, on all major operating systems with an embedded GPL barrier ZIP filesystem that is tiny enough to transpile to JavaScript and run in browsers too. https://justine.storage.googleapis.com/emulator625.mp4

Make terminal ui binaries work well everywhere Here's some screenshots of an emulator tui program that was compiled on Linux, then scp'd it to Windows, Mac, and FreeBSD. https://justine.storage.googleapis.com/blinkenlights-cmdexe.png https://justine.storage.googleapis.com/blinkenlights-imac.png https://justine.storage.googleapis.com/blinkenlights-freebsd.png https://justine.storage.googleapis.com/blinkenlights-lisp.png How is this even possible that we have a nontrivial ui binary that just works on Mac, Windows, Linux, and BSD? Surely a first ever achievement. Fixed many bugs. Bootstrapped John McCarthy's metacircular evaluator on bare metal in half the size of Altair BASIC (about 2.5kb) and ran it in emulator for fun and profit.

Add cpu / mem / fsz limits to build system Thanks to all the refactorings we now have the ability to enforce reasonable limitations on the amount of resources any individual compile or test can consume. Those limits are currently: - `-C 8` seconds of 3.1ghz CPU time - `-M 256mebibytes` of virtual memory - `-F 100megabyte` limit on file size Only one file currently needs to exceed these limits: o/$(MODE)/third_party/python/Objects/unicodeobject.o: \ QUOTA += -C16 # overrides cpu limit to 16 seconds This change introduces a new sizetol() function to LIBC_FMT for parsing byte or bit size strings with Si unit suffixes. Functions like atoi() have been rewritten too.

Add SNI support to redbean and improve SSL perf This change makes SSL virtual hosting possible. You can now load multiple certificates for multiple domains and redbean will just figure out which one to use, even if you only have 1 ip address. You can also use a jumbo certificate that lists all your domains in the the subject alternative names. This change also makes performance improvements to MbedTLS. Here are some benchmarks vs. cc1920749eb81f346badaf55fbf79620cb718a55 BEFORE AFTER (microsecs) suite_ssl.com 2512881 191738 13.11x faster suite_pkparse.com 36291 3295 11.01x faster suite_x509parse.com 854669 120293 7.10x faster suite_pkwrite.com 6549 1265 5.18x faster suite_ecdsa.com 53347 18778 2.84x faster suite_pk.com 49051 18717 2.62x faster suite_ecdh.com 19535 9502 2.06x faster suite_shax.com 15848 7965 1.99x faster suite_rsa.com 353257 184828 1.91x faster suite_x509write.com 162646 85733 1.90x faster suite_ecp.com 20503 11050 1.86x faster suite_hmac_drbg.no_reseed.com 19528 11417 1.71x faster suite_hmac_drbg.nopr.com 12460 8010 1.56x faster suite_mpi.com 687124 442661 1.55x faster suite_hmac_drbg.pr.com 11890 7752 1.53x faster There aren't any special tricks to the performance imporvements.

Add chibicc This program popped up on Hacker News recently. It's the only modern compiler I've ever seen that doesn't have dependencies and is easily modified. So I added all of the missing GNU extensions I like to use which means it might be possible soon to build on non-Linux and have third party not vendor gcc binaries.
