SCADA Security, Graph Clustering, Facebook Flipbook, and Projections Illustrated

  1. Hackers Gain ‘Full Control’ of Critical SCADA Systems (IT News) — The vulnerabilities were discovered by Russian researchers who over the last year probed popular and high-end ICS and supervisory control and data acquisition (SCADA) systems used to control everything from home solar panel installations to critical national infrastructure. More on the Botnet of Things.
  2. mclMarkov Cluster Algorithm, a fast and scalable unsupervised cluster algorithm for graphs (also known as networks) based on simulation of (stochastic) flow in graphs.
  3. Facebook to Launch Flipboard-like Reader (Recode) — what I’d actually like to see is Facebook join the open web by producing and consuming RSS/Atom/anything feeds, but that’s a long shot. I fear it’ll either limit you to whatever circle-jerk-of-prosperity paywall-penetrating content-for-advertising-eyeballs trades the Facebook execs have made, or else it’ll be a leech on the scrotum of the open web by consuming RSS without producing it. I’m all out of respect for empire-builders who think you’re a fool if you value the open web. AOL might have died, but its vision of content kings running the network is alive and well in the hands of Facebook and Google. I’ll gladly post about the actual product launch if it is neither partnership eyeball-abuse nor parasitism.
  4. Map Projections Illustrated with a Face (Flowing Data) — really neat, wish I’d had these when I was getting my head around map projections.

Dinosaur Tries to Suckle, Dashboard Design, Massive Visualizations, Massive Machine Learning

  1. Intel XDKIf you can write code in HTML5, CSS3 and JavaScript*, you can use the Intel® XDK to build an HTML5 web app or a hybrid app for all of the major app stores. It’s a .exe. What more do I need to say? FFS.
  2. Behind the Scenes of a Dashboard Design — the design decisions that go into displaying complex info.
  3. Superconductora web framework for creating data visualizations that scale to real-time interactions with up to 1,000,000 data points. It compiles to WebCL, WebGL, and web workers. (via Ben Lorica)
  4. BIDMach: Large-scale Learning with Zero Memory Allocation (PDF) — GPU-accelerated machine learning. In this paper we describe a caching approach that allows code with complex matrix (graph) expressions at massive scale, i.e. multi-terabyte data, with zero memory allocation after the initial setup.

Engineering Virality, App Store Numbers, App Store Data, and FPGA OS

  1. How To Make That One Thing Go Viral (Slideshare) — excellent points about headline writing (takes 25 to find the one that works), shareability (your audience has to click and share, then it’s whether THEIR audience clicks on it), and A/B testing (they talk about what they learned doing it ruthlessly).
  2. A More Complete Picture of the iTunes Economy — $12B/yr gross revenue through it, costs about $3.5B/yr to operate, revenue has grown at a ~35% compounded rate over last four years, non-app media 2/3 sales but growing slower than app sales. Lots of graphs!
  3. Visualizing the iOS App Store — interactive exploration of app store sales data.
  4. BORPHan Operating System designed for FPGA-based reconfigurable computers. It is an extended version of the Linux kernel that handles FPGAs as if they were CPUs. BORPH introduces the concept of a ‘hardware process’, which is a hardware design that runs on an FPGA but behaves just like a normal user program. The BORPH kernel provides standard system services, such as file system access to hardware processes, allowing them to communicate with the rest of the system easily and systematically. The name is an acronym for “Berkeley Operating system for ReProgrammable Hardware”.

Visualization Papers, Immersive Learning, Readability, and Quora's Technology

  1. Seven Foundational Visualization Papers — seven classics in the field that are cited and useful again and again.
  2. Git Immersion — a “walking tour” of Git inspired by the premise that to know a thing is to do it. Cf Learn Python the Hard Way or even NASA’s Planet Makeover. We’ll see more and more tutorials that require participation because you don’t get muscle memory by reading. (NASA link via BoingBoing
  3. Readability — strips out ads and sends money to the publishers you like. I’d never thought of a business model as something that’s imposed from the outside quite like this, but there you go.
  4. Quora’s Technology Examined (Phil Whelan) — In this blog post I will delve into the snippets of information available on Quora and look at Quora from a technical perspective. What technical decisions have they made? What does their architecture look like? What languages and frameworks do they use? How do they make that search bar respond so quickly? Lots of Python.

New Browser, Google APIs, NFC Checkin, and XSS Prevention

  1. Mozilla Home Dash — love this experiment in rethinking the browser from Mozilla. They call it a “browse-based browser” as opposed to “search-based browser” (hello, Chrome). Made me realize that, with Chrome, Google’s achieved a 0-click interface to search–you search without meaning to as you type in URLs, you see advertising results without ever having visited a web site.
  2. Periodic Table of Google APIs — cute graphic, part of a large push from Google to hire more outreach engineers to do evangelism, etc. The first visible signs of Google’s hiring binge.
  3. NFC in the Real World (Dan Hill) — smooth airline checkin with fobs mailed to frequent fliers.
  4. XSS Prevention Cheat Sheet (OWASP) — HTML entity encoding doesn’t work if you’re putting untrusted data inside a script tag anywhere, or an event handler attribute like onmouseover, or inside CSS, or in a URL. So even if you use an HTML entity encoding method everywhere, you are still most likely vulnerable to XSS. You MUST use the escape syntax for the part of the HTML document you’re putting untrusted data into. That’s what the rules below are all about. (via Hacker News)
