If you want to sell real estate while still retaining rights to visit a grave sited thereupon, the legal instrument is called an "easement". Sometimes the access grant is associated with ownership of another property (e.g. shared

My point was meant purely as an intellectual exercise, not a critique of engineering choices made in the face of adverse practical realities. My apologies if it came across otherwise. With the luxury of hindsight, allowing an admixture of 3

The hopes were for a converged software stack, but the candidates were all parallel protocols competing with IPv4. A full transition would end with the extinction of IPv4. Upgrading IPv4, quite apart from the brass tacks of the wire format,

I only read up on CLNP based on a fascination with counterfactuals. I will say there is a fair bit to IS-IS and ES-IS that's directly relevant to the original articles points on the circuits-to-bus-to-circuits physical evolution. There

CLNP had existing implementations and was fundamentally sound. On its technical merits, RFC1347 TCP and UDP with Bigger Addresses (TUBA) wins hands-down. But it took too long for the ISO to agree to a hand-off (the IETF wanted to be able _f

IPv4 was designed with extension headers: it boggles my mind that simply using the headers to extend the address was never seriously considered. It was proposed: https://www.rfc-editor.org/rfc/rfc1365.html It still wou

IPv4 will be with us for a long, long time. My point is that we're stuck with the combination in some form or another and it didn't have to be that way . Embedding the address extension using the extension mechanism built into IP

There's no viable alternative to dual stack with NAT now. We're stuck with it. But when IPv6 was standardized, a pure upgrade to IPv4 was still feasible. IPv4 allows for extensions headers and middleboxes hadn't yet imposed p

There was no upside for an ISP to operate a 6to4 relay, so the anycast address was worse than a blackhole route. It would occasionally permit a connection, but mostly just caused timeouts. Without that poison pill, it could have been a nice

As I recall, 6to4 worked beautifully between 6to4 nodes in the absence of middlebox interference. The fatal flaw was the anycast address for accessing the "real" IPv6 network. The rosy outcome imagined in the article doesn't

Dotnet's GC has a real latency problem. Miguel de Icaza gave a nice talk on why noticeable pauses are inevitable in a stop-the-world tracing GC, proposing Swift's reference-counting GC as the viable alternative [1]. Still, there a

The sentence "a 32-bit CPU register can address up to 4 gigabyte of memory" is sloppy, the sentence "a 32-bit CPU register can address up to 4 GiB of memory" is not.

Oh that's fun. I imagined a distressed elephant walking through the office and pulling down ceiling tiles, the wood floor splintering under the weight. Didn't think about ears. Attitude, mass, height, and building materials: yes.

Same here: it reduces to a logic problem. I can imagine the transformation, the space, the cube, the rotation individually as concepts, but all of it is more memory than visualization and carrying through the shape and orientation of the nu

Lately I've taken to avoiding that fine point. I find it easier to internalize `foo/bar/.`. Using the self-referential dot this way doesn't carry the same semantics, but the effect is the same and it's a pattern tha

Wow. I had a CS professor insist on exactly that style. I couldn't stand it at first, but making accommodations was the whole point. Unfortunately it got me thinking about what I would want. Now I'm the weirdo and I rarely get t

I don't know why back-to-back SSL proxies were never afforded an officially sanctioned mechanism for explicitly delegating trust. The alternative is this "I know you're lying, but I love you too much to leave you" mental

I've gone down that rabbit hole, repeatedly. It's just too fascinating. Likewise, I feel obligated to bring up the Voter Satisfaction Efficiency (or index) metric that seems to be favored by the approval/range voting crowd: b
