Android Malware Numbers, Open Networking Hardware, Winning with Data, and DIY Pollution Sensor

  1. Android Malware Numbers — (Quartz) less than an estimated 0.001% of app installations on Android are able to evade the system’s multi-layered defenses and cause harm to users, based on Google’s analysis of 1.5B downloads and installs.
  2. Facebook Operations Chief Reveals Open Networking Plan — long interview about OCP’s network project. The specification that we are working on is essentially a switch that behaves like compute. It starts up, it has a BIOS environment to do its diagnostics and testing, and then it will look for an executable and go find an operating system. You point it to an operating system and that tells it how it will behave and what it is going to run. In that model, you can run traditional network operating systems, or you can run Linux-style implementations, you can run OpenFlow if you want. And on top of that, you can build your protocol sets and applications.
  3. How Red Bull Dominates F1 (Quartz) — answer: data, and lots of it.
  4. Ground-Level Air Pollution Sensor (Make) — neat sensor project from Make.

DEFCON Doco, Global-Scale Networks, Media Goblin, and TCP/IP Legos

  1. DEFCON Documentary — free download, I’m looking forward to watching it on the flight back to NZ.
  2. Global-Scale Systems — botnets as example of the scale of networks and systems we’ll have to build but don’t have experience in.
  3. MediaGoblin — GNU project to build a decentralized alternative to Flickr, YouTube, SoundCloud, etc.
  4. Teaching TCP/IP Headers with Legos — genius. (via BoingBoing)

Transit and Peering, Quick Web Interfaces, Open Source Licensing, and RC Roach

  1. Why YouTube Buffers (ArsTechnica) — When asked if ISPs are degrading Netflix and YouTube traffic to steer users toward their own video services, Crawford told Ars that “the very powerful eyeball networks in the US (and particularly Comcast and Time Warner Cable) have ample incentive and ability to protect the IP services in which they have economic interests. Their real goal, however, is simpler and richer. They have enormous incentives to build a moat around their high-speed data networks and charge for entry because data is a very high-margin (north of 95 percent for the cable companies), addictive, utility product over which they have local monopoly control. They have told Wall Street they will do this. Yes, charging for entry serves the same purposes as discrimination in favor of their own VOD [video-on-demand], but it is a richer and blunter proposition for them.”
  2. Ink — MIT-licensed interface kit for quick development of web interfaces, simple to use and expand on.
  3. Licensing in a Post-Copyright WorldThis article is opening up a bit of the history of Open Source software licensing, how it seems to change and what we could do to improve it. Caught my eye: Oracle that relicensed Berkeley DB from BSD to APGLv3 [... effectively changing] the effective license for 106 other packages to AGPLv3 as well.

Driverless Intersections, Quantum Information, Low-Energy Wireless Networking, and Scammy Game Tactics

  1. Autonomous Intersection Management Projecta scalable, safe, and efficient multiagent framework for managing autonomous vehicles at intersections. (via How Driverless Cars Could Reshape Cities)
  2. Quantum Information (New Scientist) — a gentle romp through the possible and the actual for those who are new to the subject.
  3. Ambient Backscatter (PDF) — a new communication primitive where devices communicate by backscattering ambient RF signals. Our design avoids the expensive process of generating radio waves; backscatter communication is orders of magnitude more power-efficient than traditional radio communication. (via Hacker News)
  4. Top Free-to-Play Monetization Tricks (Gamasutra) — amazingly evil ways that free games lure you into paying. At this point the user must choose to either spend about $1 or lose their rewards, lose their stamina (which they could get back for another $1), and lose their progress. To the brain this is not just a loss of time. If I spend an hour writing a paper and then something happens and my writing gets erased, this is much more painful to me than the loss of an hour. The same type of achievement loss is in effect here. Note that in this model the player could be defeated multiple times in the boss battle and in getting to the boss battle, thus spending several dollars per dungeon.

Informed Citizenry, TCP Chaos Monkey, Photographic Forensics, Medical Trial Data

  1. Aaron’s Army — powerful words from Carl Malamud. Aaron was part of an army of citizens that believes democracy only works when the citizenry are informed, when we know about our rights—and our obligations. An army that believes we must make justice and knowledge available to all—not just the well born or those that have grabbed the reigns of power—so that we may govern ourselves more wisely.
  2. Vaurien the Chaos TCP Monkeya project at Netflix to enhance the infrastructure tolerance. The Chaos Monkey will randomly shut down some servers or block some network connections, and the system is supposed to survive to these events. It’s a way to verify the high availability and tolerance of the system. (via Pete Warden)
  3. Foto Forensics — tool which uses image processing algorithms to help you identify doctoring in images. The creator’s deconstruction of Victoria’s Secret catalogue model photos is impressive. (via Nelson Minar)
  4. All Trials Registered — Ben Goldacre steps up his campaign to ensure trial data is reported and used accurately. I’m astonished that there are people who would withhold data, obfuscate results, or opt out of the system entirely, let alone that those people would vigorously assert that they are, in fact, professional scientists.

Mark Twain on influence

A letter asking for an introduction meets a meditation on self-reliance.

In 1905 Mark Twain wrestled with the sort of request that many readers here have undoubtedly encountered: a new writer with the most tenuous of connections (her uncle was briefly a neighbor in a Nevada mining town) asks Twain to use his influence to get  her manuscript published. It never hurts to carry an introduction from a well-regarded intermediary, as…

Javascript Tips, Collections Metadata, Networking Toolkit, and Augmented Notebook

  1. Javascript Tips for Non-Specialists (OmniTI) — “hey kid, you’re going to have to write browser Javascript. Read this and you’ll avoid the obvious cowpats.”
  2. Museum Datasets (Seb Chan) — collections metadata aren’t generally in good quality (often materials are indexed at the “box level”, ie this item number is a BOX and it contains photos of these things), and aren’t all that useful. The story about the Parisian balcony grille is an excellent reminder that the institution’s collections aren’t a be-all and end-all for researchers.
  3. Hurricane Electric BGP Toolkit — open source tools for diagnosing network problems. (via Nelson Minar)
  4. Evernote Smart Notebook by Moleskine — computer vision to straighten up photographed pages of the notebook, and the app recognizes special stickers placed on the book as highlights and selections. Nifty micro-use of augmented reality.

Hologram Headliners, Javascript Stack, HTML to PDF, and Software Defined Networking

  1. Tupac Coachella Behind the Technology (CBS) — interesting to me is Dr. Dre and Snoop Dogg were considering taking Shakur with them on tour. Just as Hobbit, Tintin, etc. are CG-ing characters to look normal, is the future of “live” spectacle to be this kind of CG show? Will new acts be competing against the Rolling Stones forever?
  2. Javascript All The Way Down (Alex Russell) — points out that we’re fixing so much like compatibility, performance, accessibility, all this stuff with Javascript. We’re moving further and further from declarative programming and more and more back to the days of writing heaps of Xlib or Motif toolkit code to implement our UIs and apps.
  3. wkhtmltopdf (Google Code) — Simple shell utility to convert html to pdf using the webkit rendering engine, and qt. My first piece of “I wrote this, now you can use it too” open source was an HTML to PS converter (this was 1994 or so) via LaTeX. It’s a useful thing, no really.
  4. Nicira (Wired) — moving network management into software so the network hardware is as dumb as possible. Interesting continuation of the End-to-End principle, whereby smarts live at the edges of the network and the conduits are dumb.

Mobile Data, Startup Ideas, Sci Foo, and Instapaper

  1. The Coming Mobile Data Apocalypse (Redmonk) — it is clear that the appetite for mobile bandwidth will grow exponentially over the next twelve to eighteen months. With high volumes of smartphones shipping, more and larger form factors entering the market, and the accelerating build out of streaming services, bandwith consumption is set to spike. Equally apparent is that the carriers are ill provisioned to address this demand, both from a network capacity perspective as well as with their pricing structures.
  2. Hamster Burial Kit and 998 Other IdeasFor Seth Godin’s Alternative MBA program, this week the nine of us came up with 111 business ideas each. But ideas are only valuable when someone (like you) makes something happen. What follows are our 999 business ideas, free for the taking.
  3. Sci Foo Short Videos — questions posed to Sci Foo attendees with interesting answers. I liked “What Worries You?”
  4. Instapaper 3 Released — all the features are ones I’ve wanted, which tells me Marco is listening very closely to his customers. Again I say: Instapaper changes the way I use the web as much as RSS did.

Ethics, Regulation, TCP/IP, and Time Travel

  1. Ethics and EconomicsThis paper looks at the evidence that suggests that ethical behaviour is good for the economy.
  2. FCC to Regulate BroadbandTwo FCC officials, who spoke on the condition of anonymity, said FCC Chairman Julius Genachowski will announce Thursday that the commission considers broadband service a hybrid between an information service and a utility and that it has sufficient power to regulate Internet traffic under existing law.
  3. TCP/IP and IMS Sequence Diagrams — watch SYN, ACK, payload, etc. packets to and fro to understand what really happens each time you fetch mail or surf the web. This is what Velocity-type devops performance folks care about.
  4. How to Build a Time Machine (Daily Mail) — extremely readable article by Stephen Hawking about the possibilities of time travel.
