2015 CCC Videos — collected talks from the 32nd Chaos Computer Congress conference.
An Integrated Bayesian Approach for Effective Multi-Truth Discovery (PDF) — Integrating data from multiple sources has been increasingly becoming commonplace in both Web and the emerging Internet of Things (IoT) applications to support collective intelligence and collaborative decision-making. Unfortunately, it is not unusual that the information about a single item comes from different sources, which might be noisy, out-of-date, or even erroneous. It is therefore of paramount importance to resolve such conflicts among the data and to find out which piece of information is more reliable.
A Psychological Exploration of Engagement in Geek Culture — Seven studies (N = 2354) develop the Geek Culture Engagement Scale (GCES) to quantify geek engagement and assess its relationships to theoretically relevant personality and individual differences variables. These studies present evidence that individuals may engage in geek culture in order to maintain narcissistic self-views (the great fantasy migration hypothesis), to fulfill belongingness needs (the belongingness hypothesis), and to satisfy needs for creative expression (the need for engagement hypothesis). Geek engagement is found to be associated with elevated grandiose narcissism, extraversion, openness to experience, depression, and subjective well-being across multiple samples.
Visual Genome — a data set, a knowledge base, an ongoing effort to connect structured image concepts to language.
Google’s Software Defined Networking — [What was the biggest risk you faced rolling out the network? …] we were breaking the fate-sharing principle—which is to say we were putting ourselves in a situation where either the controller could fail without the switch failing, or the switch could fail without the controller failing. That generally leads to big problems in distributed computing, as many people learned the hard way once remote procedure calls became a dominant paradigm.
Philips Backtrack on Lightbulb DRM — In view of the sentiment expressed by our customers, we have decided to reverse the software upgrade so that lights from other brands continue to work as they did before with the Philips Hue system.
Pwning Tomorrow — EFF Publishes SF Anthology. You can expect liberties and freedoms to feature.
Face Director — Disney software to match faces between takes. We demonstrate that our method can synthesize visually believable performances with applications in emotion transition, performance correction, and timing control.
Move Fast and Fix Things — blow by blow of an engineering rewrite of some key functionality at GitHub, interesting from a “oh so that’s how they do it” point of view (if blow-by-blow engineering rewrites qualify as “interesting” to you).
Old Book Illustrations — public domain book illustrations, tagged and searchable. Yes, like Font Awesome of engraving.
Distributed Reactive Programming (A Paper a Day) — this week’s focus on reactive programming has been eye-opening for me. I find the implementation details less interesting than the simple notion that we can define different consistency models for reactive programs and reason about them.
Attacking HTTP/2 Implementations — Our talk focused on threats, attack vectors, and vulnerabilities found during the course of our research. Two Firefox, two Apache Traffic Server (ATS), and four Node-http2 vulnerabilities will be discussed alongside the release of the first public HTTP/2 fuzzer. We showed how these bugs were found, their root cause, why they occur, and how to trigger them.
The Autonomous Winter is Coming — The future of any given manufacturer will be determined by how successfully they manage their brands in a market split between Mobility customers and Driving customers.
If the Internet is Addictive, Why Don’t We Regulate It? — an excellent look at behaviourism, gambling machine flow, design-for-addiction, attention, regulation. As Schüll puts it: ‘It just seems very duplicitous to design with the goal of capturing attention, and then to put the whole burden onto the individual.’
Zipnish — using varnish as middleware for your microservices, with Zipnish to create Zipkin-style analysis of your API performance.
Behind the Hoverboard Craze (BoingBoing) — Bernstein is interested in this phenomenon as “memeufacturing” — a couple of social-media stars (or garden-variety celebs) post viral videos of themselves using an obscure gadget, and halfway around the world, factories shut down their e-cig lines and convert them, almost overnight, to hoverboard manufacturing lines. Bernstein cites a source who says that there are 1,000 hoverboard factories in South China.
neural-vqa — VIS+LSTM model for Visual Question Answering. Scroll to the end and see the questions it’s answering about photos.
Open Season in Editing Genes of Animals (NY Times) — “We’re going to see a stream of edited animals coming through because it’s so easy,” said Bruce Whitelaw, a professor of animal biotechnology at the Roslin Institute at the University of Edinburgh. “It’s going to change the societal question from, ‘If we could do it, would we want it?’ to, ‘Next year we will have it; will we allow it?’”
RTS AI (PDF) — standard techniques used for playing classic board games, such as game tree search, cannot be directly applied to solve RTS games without the definition of some level of abstraction, or some other simplification. Interestingly enough, humans seem to be able to deal with the complexity of RTS games, and are still vastly superior to computers in these types of games. Talks about the challenges in writing AIs for Real-Time Strategy games.
Algorithms for Affective Sensing — Results show that the system achieves a six-emotion decision-level correct classification rate of 80% for an acted dataset with clean speech. This PhD thesis is research into algorithm for determining emotion from speech samples, which does so more accurately than humans in a controlled test. (via New Scientist)
DeepDive — Stanford project to create structured data (SQL tables) from unstructured information (text documents) and integrate such data with an existing structured database. DeepDive is used to extract sophisticated relationships between entities and make inferences about facts involving those entities. Code is open source (Apache v2 license). (via Infoworld)
Visual Microphone (MIT) — turn everyday objects — a glass of water, a potted plant, a box of tissues, or a bag of chips — into visual microphones using high-speed photography to detect the small vibrations caused by sound. (via Infoworld)
