Software Supply Chain Attack

Joel Wallenberg interviewed me on 14^th February for his article in the 28^th February edition of Grant's Interest Rate Observer entitled Memo to the bitcoiners. Alas, it is paywalled, but among the many quotes from me Wallenberg used was that blockchain-based systems "are very vulnerable to supply-chain attacks".

Exactly a week after the interview and a week before the article went to press, we got an example, the biggest cryptocurrency heist in history. Below the fold I discuss the details.

Bitcoin's Fee Spikes

I've written several times, for example in Fixed Supply, Variable Demand, about the mechanism that causes the cost of transacting on a blockchain like Bitcoin's to suffer massive spikes at intervals. When no-one wants to transact, fees are low. When everyone does, they are high. Below the fold I look in detail at a typical Bitcoin fee spike.

Archival Storage

I gave a talk at the Berkeley I-school's Information Access Seminar entitled Archival Storage. Below the fold is the text of the talk with links to the sources and the slides (with yellow background).

The Oligopoly Publishers

Rupak Ghose's The $100 billion Bloomberg for academics and lawyers? is essential reading for anyone interested in academic publishing. He starts by charting the stock price of RELX, Thomson Reuters, and Wolters Kluwer, pointing out that in the past decade they have increased about ten-fold. He compares these publishers to Bloomberg, the financial news service. They are less profitable, but that's because their customers are less profitable. Follow me below the fold for more on this.
