Telepresent Axeman, Toxic Workers, Analysis Code, and Cryptocurrency Attacks

  1. Axe-Wielding Robot w/Telepresence (YouTube) — graphic robot-on-wall action at 2m30s. (via IEEE)
  2. Toxic Workers (PDF) — In comparing the two costs, even if a firm could replace an average worker with one who performs in the top 1%, it would still be better off by replacing a toxic worker with an average worker by more than two-to-one. Harvard Business School research. (via Fortune)
  3. Replacing Sawzall (Google) — At Google, most Sawzall analysis has been replaced by Go […] we’ve developed a set of Go libraries that we call Lingo (for Logs in Go). Lingo includes a table aggregation library that brings the powerful features of Sawzall aggregation tables to Go, using reflection to support user-defined types for table keys and values. It also provides default behavior for setting up and running a MapReduce that reads data from the logs proxy. The result is that Lingo analysis code is often as concise and simple as (and sometimes simpler than) the Sawzall equivalent.
  4. Attacks in the World of Cryptocurrency — a review of some of the discussed weakness, attacks, or oddities in cryptocurrency (esp. bitcoin).
