@RUSHIFA Bach. "But what piece of Bach?" I hear you cry, "there are so many?" Yes, and they are all good.

@augustus wireguard users be like "lol trust the plan? I don't even trust the LAN" #networkingmemes

@protoneutype I realise this might not work for everyone but I find making music is a fairly reliable way to get the endorphins flowing again in that situation. Combination of motor activation, structured sensory experience & sense of accomplishment when you get to the end of a tricky piece/passage. (If you're unmusical, there're probably other things with the same features... I dunno, handicrafts? Woodwork?)

@amir Isn't that AU he describes basically HPMOR? (Which is, indeed, the Best Thing.)

@iamnoah yeah, shoulda used ed

@Counsel in a debate, it's a fallacy to accuse your opponent of being a white rapper. Argumentum ad eminem.

@StevenFan Probably the best thing to learn about is #XDP & #eBPF.
XDP: start here https://www.iovisor.org/technology/xdp
eBPF is the enabling technology for XDP (and much more besides), https://ebpf.io/

With XDP, the network becomes programmable at the kernel layer. E.g. Facebook's load-balancer uses XDP for the fast path https://engineering.fb.com/2018/05/22/open-source/open-sourcing-katran-a-scalable-network-load-balancer/ — easy to see how this kind of multiple point-of-presence could be useful to a self-hosted DC network facing political attacks on its edge connectivity…

@duponin I think you also need to enable the sysctl net.ipv4.ip_forward. Equivalent for ipv6 is way more complicated (like everything) — https://unix.stackexchange.com/questions/348533/

@StevenFan oh, I'm already doing _that_ (e.g. in #Linuxgate I spoke out against the new CoC). I was asking more about _technical_ measures: what kinds of features in the networking subsystem would be useful to a RW datacentre fending off such attacks? Better support for multihoming? MPTCP? A 'reverse load balancer' (maybe XDP based) to shunt flows around between different ISP uplinks?

The future belongs to those who show up to build it, so what should I _build_ to get the future we want?

Intuitive way to understand the intermediate axis theorem: angular momentum is Iω but K.E. is ½Iω²; momentum is conserved but K.E. can dissipate; thus only max & min I are in equilibrium, and only max I (i.e. min K.E.) is long-term stable.

(This is not really rigorous, as it doesn't prove there aren't other stationary points of Iω̂, but it's close enough & helps to remember which axis is the stable one.)

@StevenFan Anything a freedom-loving developer involved in the Linux kernel network stack could do to help increase robustness against such attacks? Asking for a friend...

@danzaburou I realised a couple of years back that I already had no opsec — I'd said enough in public to paint a target on me — so now I just let my real name stand behind my words, even unto anarchist rants. It's oddly liberating.
