   Depends on your needs, but having your data & database multi-az to ensure durability can avoid you having to restart from backups. I'm thinking about an old AWS incident were they actually lost EBS data: https://www.blee

   I also love OCSP stapling but there are some limitations: - webserver need to implement it - admin need to enable it - webserver need internet access Maybe they saw with some telemetry that very few website actually enable OCSP stampling an

   A fantastic thing about HyperLogLog is that it can be merged, so you can split your data between multiple server, precompute HLL for all IPs every minute, and then ask "how many unique IPs was there yesterday". Discovered HLL beca

   HPE had the same issue on some of their SSDs. We received an advisory months before it would have been a problem, and had time to upgrade all our customers ... except 2 servers that we missed. Luckily when I saw all disk in error in the iLO

    MetalLB is the best baremetal LB (for k8s) but far from perfect indeed. For the IP conflicts, there are other private IPv4 range that you can use, just pick something in the CGNAT range (100.64.0.0/10) or in 198.18.0.0/15 ("U

    Why are we adjusting when after 100 years clock would be less than 1 min off. We should deprecate UTC and just use TAI, ~40s difference right now.

    Our energy usage will definitely decrease and I'm all for it, I just hope it's in a controlled way and not a brutal collapse. I'm talking "short" term, if you shutdown nuclear plant for political reasons, you just b

    Presidential election is next year and some candidates want to completely get rid of nuclear as fast as possible, so this can change. Not sure these candidates understand this means more CO2, bigger dependency on Russia for gaz and more exp

    PSA: AllowedCPUs only works with systemd.unified_cgroup_hierarchy=1. Until Docker 20.10 you needed unified_cgroup_hierarchy=0, and Ubuntu just switched in 21.10.

    OpenWrt doesn't use proprietary drivers and instead try to ships really recent kernel (21.02 ships 5.4, master has 5.10), so that might be why your particular model will never be supported. dd-wrt seems to be maintaining some eol kerne

    Many distro default to iptables-nft, RHEL 8 went further and is not providing iptables-legacy binary at all. RHEL 8 still has iptables in the kernel, I think to allow container sidecars to still work with iptables-legacy.
