Dɛn ne copy-and-patch compiler ma Python?

Copy-and-patch compiler yɛ ɔkwan a wɔfa so yɛ mfiri koodu denam binary templates (stencils) a wɔadi kan aboaboa ano a ɛyɛ copy ne patching wɔ runtime values mu, sen sɛ ɛbɛkyekye code fi mfiase denam atetesɛm compilation stages so. Wɔ Python fam no, saa kwan yi ma wotumi di ahoɔhare a ɛbɛn-native execution speed a compilation latency a ɛba fam koraa, na ɛma ɛyɛ yiye ma hard real-time systems a bere ho bɔhyɛ a wotumi hyɛ ho nkɔm no ho hia.

Ɔkwan bɛn so na eyi yɛ soronko wɔ Python JIT compilers a wɔtaa yɛ no ho?

Atetesɛm JIT compilers te sɛ nea ɛwɔ PyPy mu no fa optimization passes a ɛyɛ den a ɛde compilation pauses a wontumi nhyɛ da nkyerɛ — ɛyɛ ɔhaw ma bere ankasa mu adwumayɛ. Copy-and-patch compilation yɛ fapem ntɛmntɛm na ɛyɛ deterministic efisɛ ɛkwati heavyweight optimization. Anamɔn a wɔaboaboa ano no ankasa kɔ so wɔ bere a anohyeto wom mu, a ɛho hia bere a wuhia mmuae bere a wɔahyɛ ho bɔ wɔ nhyehyɛe a wɔde ahyɛ mu, robɔt, anaa ɔdio dwumadie nsuo afiri mu.

So wobetumi de Python adi dwuma ampa wɔ bere ankasa mu tebea horow a ɛyɛ den mu?

Standard CPython ntumi nni bere ankasa anohyeto a emu yɛ den ho dwuma esiane nwura a wɔboaboa ano a wɔde gyina hɔ ne nkyerɛasefo a ɛwɔ soro nti. Nanso, copy-and-patch compiler a ɔde ahwɛyiye hwɛ memory so betumi ama deterministic execution paths aba. Wei bue Python kɔ domains a kan no na wɔabara wɔ C anaa Rust so. Wɔ developers a wɔrehwehwɛ saa cutting-edge techniques, platforms te sɛ Mewayz aggregate 207 curated modules kata systems programming ne performance engineering — ne nyinaa yɛ nea wobetumi anya afi $19/mo.

Ɛhe na metumi asua pii afa compiler design ne real-time systems ho?

Hacker News nkɔmmɔbɔ a edi kan no de nkitahodi kɔ adwuma no fibea koodu ne mfiridwuma ho nkrataa so. Sɛ wopɛ adesua kwan a wɔahyehyɛ a ɛkata compiler internals, low-level optimization, ne systems programming fundamentals so a, Mewayz de modules 207 a animdefoɔ ahwɛ so a ɛfa saa nsɛmti yi ho ma $19/mo — ɛma wo fapem a ɛkɔ akyiri a wode bɛte aseɛ na woaboa ama nnwuma te sɛ yei.
