(Not who you are replying to) Not sure if it’s specifically related to DBSP but checkout incremental DataFun (slide ~55 of https://www.rntz.net/files/stl2017-datafun-slides.pdf) and the paper cited there: A Theory of Changes for Higher Order Languages: Incrementalizing Lambda-calculi by Static Differentiation (Cai et. al, PLDI 2014).

I'm surprised no one has yet done React SSR in Rails using Graal (using the polyglot bridge between Rails running on Truffleruby and React on Graal.js).

How does Tilt compare to Skaffold? (I just got skaffold set up)

Came here to mention these two books.

What are the advantages of Lulu over Little Snitch?

Thanks for writing this up. I saw your original comment a while back was intrigued, and I got it working last weekend on a 2-vm vagrant private network setup, but only by constructing the network prefix by using a 32 bit ULA prefix concatenated on the full 32 bit ipv4. I think it worked (hooked up wireshark to a tcpdump of the vm's interface to the private network and saw the 6-in-4 packets) but I didn't need to use the `6rd-relay_prefix` argument to ip tunnel, do you have any idea why that might be? I suspect 32+32 is the default (vs. your 40+24), and if you want to only use the lower 24 bits of the ipv4, you need to indicate to the kernel what netmask you are using on your ipv4 network ("6rd relay prefix"). I guess that would buy you either more randomness in your ULA prefix, or some more ipv6 subnets per ipv4 vm.

You can explore this a bit further and set up some net namespaces, connect them to the host vm via a bridge device, assign them ipv6 addresses from the vm host /64 network, and then set up a default route inside each container to the /32 or /40 you're using via the vm host's address on the host local /64. It's cool to see one container on host 1 talk to another on host 2. You're basically subnetting the /40 for each host; each host is analogous to a household in 6rd, and the containers are like your devices on your lan with globally routable ipv6 addresses (except we're using a ULA prefix instead of a globally routable ipv6 prefix assigned to an ISP, so our containers are not globally addressable - whatever). I'd guess this is what the CNI thing you mention does under the hood. For others who are interested in this, it's basically combining OP's article with https://iximiuz.com/en/posts/container-networking-is-simple/ from a couple months ago.

The Teredo part was very interesting as well, I had not thought to worry about non-udp/tcp compatible intermediate systems.

No RSS feed for this blog?

Tailscale looks awesome but I would love a tier between “free single user with gmail” and “$10/user/month + GSuite/etc” (GSuite itself is $5/user/month I think?). Something like 1Password’s family plan, with the ability to use gmail accounts.

Then I would use it for my family, e.g. I could replace DynDNS + port forwarding I set up so my dad can control his home automation software (Hass.io) from his iPhone app, even off the WiFi. I’m unfortunately just not willing to set up/shell out for GSuite/Active Directory/Office365 for my family.

What really hooked me was your story about the medical practice a little while back.

Why would I get a new numpad when I can do this with vi/emacs/etc. macros?

This title is extremely misleading. Makes it sounds like there has been a nuclear accident, and subtly stokes fears of nuclear technology.
