As Stanford staff I get a feel-good email every morning full of stuff about the wonderful things Stanford is doing. Last Thursday's linked to this article from the medical school about Stanford's annual Big Data in Biomedicine conference. It is full of gee-whiz speculation about how the human condition can be improved if massive amounts of data is collected about every human on the planet and shared freely among medical researchers. Below the fold, I give a taste of the speculation and, in my usual way, ask what could possibly go wrong?
I'm David Rosenthal, and this is a place to discuss the work I'm doing in Digital Preservation.

Time for another IoT rant
I haven't posted on the looming disaster that is the Internet of Things You Don't Own since last October, although I have been keeping track of developments in brief comments to that post. The great Charlie Stross just weighed in with a brilliant, must-read examination of the potential the IoT brings for innovations in rent-seeking, which convinced me that it was time for an update. Below the fold, I discuss the Stross business model and other developments in the last 8 months.

Bad incentives in peer-reviewed science
The inability of the peer-review process to detect fraud and error in scientific publications is getting some mainstream attention. Adam Marcus and Ivan Oransky, the founders of Retraction Watch, had an op-ed in the New York Times entitled What's Behind Big Science Frauds?, in which they neatly summed up the situation:
Economists like to say there are no bad people, just bad incentives. The incentives to publish today are corrupting the scientific literature and the media that covers it. Until those incentives change, we’ll all get fooled again.Earlier this year I saw Tom Stoppard's play The Hard Problem at the Royal National Theatre, which deals with the same issue. The tragedy is driven by the characters being entranced by the prospect of publishing an attention-grabbing result. Below the fold, more on the problem of bad incentives in science.

Unrecoverable read errors
Trevor Pott has a post at The Register entitled Flash banishes the spectre of the unrecoverable data error in which he points out that while disk manufacturers quoted Bit Error Rates (BER) for hard disks are typically 10-14 or 10-15, SSD BERs range from 10-16 for consumer drives to 10-18 for hardened enterprise drives. Below the fold, a look at his analysis of the impact of this difference of up to 4 orders of magnitude.

I started blogging about the transition the Web is undergoing from a document to a programming model, from static to dynamic content, some time ago. This transition has very fundamental implications for Web archiving; what exactly does it mean to preserve something that is different every time you look at it? Not to mention the vastly increased cost of ingest, because executing a program takes a lot more, a potentially unlimited amount of, computation than simply parsing a document.

A good op-ed on digital preservation
Bina Venkataraman was White House adviser on climate change innovation and is now at the Broad
Foundation Institute working on long-term vs. short-term issues. She has a good op-ed piece in Sunday's Boston Globe entitled The race to preserve disappearing data. She and I e-mailed to and fro as she worked on the op-ed, and I'm quoted in it.
Update: Bina's affiliation corrected - my bad.

Potemkin Open Access Policies
Last September Cameron Neylon had an important post entitled Policy Design and Implementation Monitoring for Open Access that started:
We know that those Open Access policies that work are the ones that have teeth. Both institutional and funder policies work better when tied to reporting requirements. The success of the University of Liege in filling its repository is in large part due to the fact that works not in the repository do not count for annual reviews. Both the NIH and Wellcome policies have seen substantial jumps in the proportion of articles reaching the repository when grantees final payments or ability to apply for new grants was withheld until issues were corrected.He points out that:
Monitoring Open Access policy implementation requires three main steps. The steps are:He makes three important recommendations:
Each of these steps are difficult or impossible in our current data environment. Each of them could be radically improved with some small steps in policy design and metadata provision, alongside the wider release of data on funded outputs.
- Identify the set of outputs are to be audited for compliance
- Identify accessible copies of the outputs at publisher and/or repository sites
- Check whether the accessible copies are compliant with the policy
- Identification of Relevant Outputs: Policy design should include mechanisms for identifying and publicly listing outputs that are subject to the policy. The use of community standard persistable and unique identifiers should be strongly recommended. Further work is needed on creating community mechanisms that identify author affiliations and funding sources across the scholarly literature.
- Discovery of Accessible Versions: Policy design should express compliance requirements for repositories and journals in terms of metadata standards that enable aggregation and consistent harvesting. The infrastructure to enable this harvesting should be seen as a core part of the public investment in scholarly communications.
- Auditing Policy Implementation: Policy requirements should be expressed in terms of metadata requirements that allow for automated implementation monitoring. RIOXX and ALI proposals represent a step towards enabling automated auditing but further work, testing and refinement will be required to make this work at scale.

Barry Ritholtz points me to Ben Thompson's post The AWS IPO, in which he examines Amazon's most recent financials. They're the first in which Amazon has broken out AWS as a separate line of business, so they are the first to reveal the margins Amazon is achieving on their cloud business. The answer is:
AWS is very profitable: $265 million in profit on $1.57 billion in sales last quarter alone, for an impressive (for Amazon!) 17% net margin.The post starts by supposing that Amazon spun out AWS via an IPO:
One of the technology industry’s biggest and most important IPOs occurred late last month, with a valuation of $25.6 billion dollars. That’s more than Google, which IPO’d at a valuation of $24.6 billion, and certainly a lot more than Amazon, which finished its first day on the public markets with a valuation of $438 million.It concludes:
The profitability of AWS is a big deal in-and-of itself, particularly given the sentiment that cloud computing will ultimately be a commodity won by the companies with the deepest pockets. It turns out that all the reasons to believe in AWS were spot on: Amazon is clearly reaping the benefits of scale from being the largest player, and their determination to have both the most complete and cheapest offering echoes their prior strategies in e-commerce.Thompson's post is a must-read; I've only given a small taste of it. But it clearly demonstrates that even AWS overall is very profitable, let alone the profitability of S3, its storage service, which I've been blogging about for more than three years.

Max Planck Digital Library on Open Access
Ralf Schimmer of the Max Planck Society's Digital Library gave a fascinating presentation (PPT) as part of a panel entitled What Price Open Access at the recent CNI meeting. He, and co-authors Kai Karin Geschuhn and Andreas Vogler have now posted the paper on which it was based, Disrupting the subscription journals' business model for the necessary large-scale transformation to open access. Their argument is:
Below the fold, I look at some of the details in the paper.
All the indications are that the money already invested in the research publishing system is sufficient to enable a transformation that will be sustainable for the future. There needs to be a shared understanding that the money currently locked in the journal subscription system must be withdrawn and re-purposed for open access publishing services. The current library acquisition budgets are the ultimate reservoir for enabling the transformation without financial or other risks.They present:
generic calculations we have made on the basis of available publication data and revenue values at global, national and institutional levels.These include detailed data as to their own spending on open access article processing charges (APCs), which they have made available on-line, and from many other sources including the Wellcome Trust and the Austrian Science Fund. They show that APCs are less than €2.0K/article while subscription costs are €3.8-5.0K/article, so the claim that sufficient funds are available is credible. It is important to note that they exclude hybrid APCs such as those resulting from the stupid double-dipping deals the UK made; these are "widely considered not to reflect a true market value". As an Englishman, I appreciate under-statement. Thus they support my and Andrew Odlyzko's contention that margins in the academic publishing business are extortionate.
Below the fold, I look at some of the details in the paper.

Talk at IIPC General Assembly
The International Internet Preservation Consortium's General Assembly brings together those involved in Web archiving from around the world. This year's was held at Stanford and the Internet Archive. I was asked to give a short talk outlining the LOCKSS Program, explaining how and why it differs from most Web archiving efforts, and how we plan to evolve it in the near future to align it more closely with the mainstream of Web archiving. Below the fold, an edited text with links to the sources.
