This reminds me of a= couple of months ago at OpenHack Victoria someone was trying to convince= me that the kernel needed a JavaVM. (Sure we each had a few beers) but t= he similarity of this discussion doesn't escape me. Kernel modules and fu= nctions written in java^H^H^H^H rust: why? I don't think that's a fair comparison at all. Rust is a systems language built around zero-cost abstractions that is usable for developing real embedded code. Java is a completely different animal, and there is no reasonable case for a Java VM in the kernel/loader. I'm all for discussion and criticism of this, that's why I posted it, but I don't think these kinds of false equivalences are helpful. --40zQJvQINjrS8i7U0w9C4z0duC53dUJgc-- --tu7wwqLaLNvV59iK66RVuCN4u9LNuo2ra Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEARYIAB0WIQQPGL/SuSPN3pRzpwUI38IpFsHCbAUCXCuMRAAKCRAI38IpFsHC bHY3AQCDvPAHFbW1JT3DBWwCkudLd5Bntp3gY3ndp+1Teniu3wEA1A7EuCvvQHU5 7VijnVFjFc9awBL0qNGEtMTgIzGw+AM= =wwev -----END PGP SIGNATURE----- --tu7wwqLaLNvV59iK66RVuCN4u9LNuo2ra--
