   @lispi314 @gentoobro @rheaplex there's usually a different layer of the onion that is supposed to perform the checksums. i don't recall what QUIC uses, but TCP is supposed to use CRC i think?

     @gentoobro @lispi314 @rheaplex a lot of reinventions of TCP came about because TCP is hopeless and they wouldn't allow us to have SCTP. SCTP has some really neat bennies but they just refuse to roll out any hardware with it.
     
     so we had to reinvent the world on UDP, which had lead to a lot of incompatible reinventions.
     
     even for things like streaming they'ev basically kept all of the effective multicast protocols locked away in to the private TV networks and refused to let the greater internet have them

     @gentoobro @lispi314 @rheaplex also isn't the only reason ecc ram isn't ubiquitous because intel is doing a retardo
     
     seem to recall its very similar to the 44khz vs 48khz nonsense audio went through. "because we could."

     Intel is the reason, though it wouldn't have been everywhere even without them. It's a tad more expensive (secret extra bits after all), and it was slower than non ECC ram in the past.

     @gentoobro @rheaplex @lispi314 i seem to recall attempts were made to push consumer level ECC. but intel basically said no. only for corpos.

     @lispi314 @icedquinn @gentoobro @rheaplex QUIC jumps straight to cryptographically authenticating each packet - it provides a rather stronger check than CRC32 :)

     @icedquinn @rheaplex @gentoobro Yeah, TCP uses CRC32s iirc. A specific variant.
     
     UDP meanwhile only uses checksums optionally, so QUIC needs to handle that itself.
     
     In IPv6 the default is that the field is mandatory (it wasn't in IPv4) *but* it's still allowed to use all-zero checksums to indicate the field is unused.
