Software Liability: US vs. EU
I have written before about the double-edged sword of software vendors' ability to disclaim liability for the performance of their products. Six years ago I wrote The Internet of Torts about software embedded in the physical objects of the Internet of Things. Four years ago I wrote about
Liability In The Software Supply Chain.
Last October, Tom Uren wrote The EU Throws a Hand Grenade on Software Liability:

The EU and U.S. are taking very different approaches to the introduction of liability for software products. While the U.S. kicks the can down the road, the EU is rolling a hand grenade down it to see what happens.It is past time to catch up on this issue, so follow me below the fold.

On Not Being Immutable

Economist 2/1/25 |
Back in November of 2022 I added an entry to this blog's list of Impossibilities for The Compliance-Innovation Trade-off from the team at ChainArgos. It started:
tl;dr: DeFi cannot be permissionless, allow arbitrary innovation and comply with any meaningful regulations. You can only choose two of those properties. If you accept a limited form of innovation you can have two-and-a-half of them.Two years later, the "more formal work" has finally been published in a peer-reviewed Nature Publishing journal, Scientific Reports, which claims to be the 5th most cited journal in the world. Jonathan Reiter tells me that, although the publishing process took two years, it did make the result better.
Fundamental results in logic and computer science impose a trade-off on any permissionless system’s ability to both permit innovation and achieve compliance with non-trivial regulations. This result depends only on long-settled concepts and the assumption a financial system must provide a logically consistent view of payments and balances to users.
This is a semi-technical treatment, with more formal work proceeding elsewhere.
Below the fold I discuss Tradeoffs in automated financial regulation of decentralized finance due to limits on mutable turing machines by Ben Charoenwong, Robert M. Kirby & Jonathan Reiter.

Vicky and I are honored and astonished by this award. Honored because it is the premiere award in the field, and astonished because we left the field more than seven years ago to take up our new full-time career as grandparents. We are all the more astonished because we are not even eligible for the award; the rules clearly state that the "award will be granted to an individual".
You can tell this is an extraordinary honor from the list of previous awardees, and the fact that it is the first time it has been awarded in successive years. Vicky and I are extremely grateful to the Association of Research Libraries, CNI and EDUCAUSE, who sponsor the award.

The work that the award recognizes was not ours alone, but the result of a decades-long effort by the entire LOCKSS team. It was made possible by support from the LOCKSS community and many others, including Michael Lesk then at NSF, Donald Waters then at the Mellon Foundation, the late Karen Hunter at Elsevier, Stanford's Michael Keller and CNI's Cliff Lynch.

A Prophet Of The Web

To give you some idea of the context in which it was written, unless you are over 70, it was more than half your life ago when in November 1989 Tim Berners-Lee's browser first accessed a page from his Web server. It was only about the same time that the first commercial, as opposed to research, Internet Service Providers started with the ARPANET being decommissioned the next year. Two years later, in December of 1991, the Stanford Linear Accelerator Center put up the first US Web page. In 1992 Tim Berners-Lee codified and extended the HTTP protocol he had earlier implemented. It would be another two years before Netscape became the first browser to support HTTPS. It would be two years after that before the ITEF approved HTTP/1.0 in RFC 1945. As you can see, Lynch was writing among the birth-pangs of the Web.
Although Lynch was insufficiently pessimistic, he got a lot of things exactly right. Below the fold I provide four out of many examples.

a rude word meaning to try to persuade someone or make them admire you by saying things that are not trueThe essence of successful bullshit is that it should be both plausible and presented authoritatively. Bullshitters are always tempted to buttress the appearance of authority by including actual evidence rather than just their interpretation of the evidence, but this is often a fatal mistake. Below the fold I discuss a classic example from MAGA's campaign to demonize immigrants.
