Major news out of @Google's security blog: Android 13 is the first Android release where a majority of new code added to the release is in a memory safe language. This is a great step forward for memory safety! security.googleblog.com/2022…

@letsencrypt are really quite lucky they only issue 90 day certs, as a serial number would only ever need to be in the CRL for 90 days (revoked and non-expired), so, coupled with the 128 shards, their CRLs will mostly be really quite small at all times!
