到了20世纪20年代,在宜昌三峡西陵峡口,一位英国植物爱好者发现了3000多亩天然野生蜡梅。他将蜡梅制作成标本,向国际传播,宜昌蜡梅被世界所知,我国是蜡梅原产地也得到证实。
The performance characteristics are attractive with incredibly fast cold starts and minimal memory overhead. But the practical limitation is language support. You cannot run arbitrary Python scripts in WASM today without compiling the Python interpreter itself to WASM along with all its C extensions. For sandboxing arbitrary code in arbitrary languages, WASM is not yet viable. For sandboxing code you control the toolchain for, it is excellent. I am, however, quite curious if there is a future for WASM in general-purpose sandboxing. Browsers have spent decades solving a similar problem of executing untrusted code safely, and porting those architectural learnings to backend infrastructure feels like a natural evolution.
