Neural Memory Allocation, DoD Synthbio, Sierra Leone Makers, and Complex Humanities Networks
- Memory Allocation in Brains (PDF) — The results reviewed here suggest that there are competitive mechanisms that affect memory allocation. For example, new dentate gyrus neurons, amygdala cells with higher excitability, and synapses near previously potentiated synapses seem to have the competitive edge over other cells and synapses and thus affect memory allocation with time scales of weeks, hours, and minutes. Are all memory allocation mechanisms competitive, or are there mechanisms of memory allocation that do not involve competition? Even though it is difficult to resolve this question at the current time, it is important to note that most mechanisms of memory allocation in computers do not involve competition. Does the dissector use a slab allocator? Tip your waiter, try the veal.
- Living Foundries (DARPA) — one motivating, widespread and currently intractable problem is that of corrosion/materials degradation. The DoD must operate in all environments, including some of the most corrosively aggressive on Earth, and do so with increasingly complex heterogeneous materials systems. This multifaceted and ubiquitous problem costs the DoD approximately $23 Billion per year. The ability to truly program and engineer biology, would enable the capability to design and engineer systems to rapidly and dynamically prevent, seek out, identify and repair corrosion/materials degradation.

- Innovate Salone — finalists from a Sierra Leone maker/innovation contest. Part of David Sengeh‘s excellent work.
- Arts, Humanities, and Complex Networks — ebook series, conferences, talks, on network analysis in the humanities. Everything from Protestant letter networks in the reign of Mary, to the repertory of 16th century polyphony, to a data-driven update to Alfred Barr’s diagram of cubism and abstract art (original here).
Inside Anonymous, Kanban Board, Extending Objective C, and Football Graphs
- How Anonymous Works (Wired) — Quinn Norton explains how the decentralized Anonymous operates, and how the transition to political activism happened. Required reading to understand post-state post-structure organisations, and to make sense of this chaotic unpredictable entity.
- Kanban For 1 — very nice progress board for tasks, for the lifehackers who want to apply agile software tools to the rest of their life.
- libextobj (GitHub) — library of extensions to Objective C to support patterns from other languages. (via Ian Kallen)
- Graph Theory to Understood Football (Tech Review) — players are nodes, passes build edges, and you can see strengths and strategies of teams in the resulting graphs.
On Anonymous, Graph Database, Leap Second, and Debugging Creativity
- In Flawed, Epic Anonymous Book, the Abyss Gazes Back (Wired) — Quinn Norton’s review of a book about Anonymous is an excellent introduction to Anonymous. Anonymous made us, its mediafags, masters of hedging language. The bombastic claims and hyperbolic declarations must be reported from their mouths, not from our publications. And yet still we make mistakes and publish lies and assumptions that slip through. There is some of this in all of journalism, but in a world where nothing is true and everything is permitted, it’s a constant existential slog. It’s why there’s not many of us on this beat.
- Titan (GitHub) — Apache2-licensed distributed graph database optimized for storing and processing large-scale graphs within a multi-machine cluster. Cassandra and HBase backends, implements the Blueprints graph API. (via Hacker News)
- Extra Second This June — we’re getting a leap second this year: there’ll be 2012 June 30, 23h 59m 60s. Calendars are fun.
- On Creativity (Beta Knowledge) — I wanted to create a game where even the developers couldn’t see what was coming. Of course I wasn’t thinking about debugging at this point. The people who did the debugging asked me what was a bug. I could not answer that. — Keita Takahashi, game designer (Katamari Damacy, Noby Noby Boy). Awesome quote.
- Interview: Hanno Sander on Robotics (Circuit Cellar) — this is what Mindstorms wants to be when it grows up. AAA++ for teaching kids. Hanno is a Kiwi Foo Camper.
- Context Needed: Benchmarks — Benchmarks fall into a few common traps because of under-reporting in context and lack of detail in results. The typical benchmark report doesn’t reveal the benchmark’s goal, full details of the hardware and software used, how the results were edited if at all, how to reproduce the results, detailed reporting on the system’s performance during the test, and an interpretation and explanation of the results.

- Morris.js (GitHub) — a lightweight library that uses jQuery and Raphaël to make drawing time-series graphs easy.
- Bret Victor: Inventing on Principle (Vimeo) — the first 20m has amazing demos of a coding environment with realtime feedback. Must see this! (via Sacha Judd)
