3D Code, Malbuffering, p2p Hardware, and Crypto Challenges

  1. Meshlabopen source, portable, and extensible system for the processing and editing of unstructured 3D triangular meshes.
  2. HTML5 Video on iOS (Steve Souders) — While it’s true that Mobile Safari on iOS doesn’t buffer any video data as a result of the PRELOAD attribute, it does make other video requests that aren’t counted as “buffered” video. The number and size of the requests and responses depends on the video. For larger videos the total amount of data for these behind-the-scenes requests can be significant.
  3. Space Monkey (Kickstarter) — distributed encrypted peer-to-peer cloud service using custom hardware. Not open source, which would make me nervous that I was buying a botnet client with storage capability. (via BERG London)
  4. Matasano Crypto ChallengesCounting is not a hard problem. But cryptography is. There are just a few things you can screw up to get the size of a buffer wrong. There are tens, probably hundreds, of obscure little things you can do to take a cryptosystem that should be secure even against an adversary with more CPU cores than there are atoms in the solar system, and make it solveable with a Perl script and 15 seconds. Don’t take our word for it: do the challenges and you’ll see. People “know” this already, but they don’t really know it in their gut, and we think the reason for that is that very few people actually know how to implement the best-known attacks. So, mail us, and we’ll give you a tour of them.

Indiepocalypse Continued, Unblockable p2p Twitter, Disposable Satellites, and iOS to HTML5

  1. Indiepocalypse: Harlem Shake Edition (Andy Baio) — “After four weeks topping the Billboard Hot 100, Macklemore and Ryan Lewis’s “Thrift Shop” was replaced this week by Baauer’s “Harlem Shake,” the song that inspired the Internet meme.”
  2. SplinterNet — an Android app designed to create an unblockable Twitter like network that uses no cellular or Internet communications. All messages are transmitted over Bluetooth between users, creating a true peer-to-peer messaging system. All messages are anonymous to prevent retaliation by government authorities. (via Ushahidi)
  3. Disposable Satellites (Forbes) — “tiny, near-disposable satellites for use in getting battlefield surveillance quickly [...] launched from a jet into orbit, and within a few minutes [...] provide soldiers on the ground with a zoomed-in, birds-eye view of the battlefield. Those image would be transmitted to current communications devices, and the company is working to develop a way to transmit them to smartphones, as well.”
  4. Native iOS to HTML5 Porting Tool (Intel) — essentially a source-to-source translator that can handle a number of conversions from Objective-C into JavaScript/HTML5 including the translation of APIs calls. A number of open source projects are used as foundation for the conversion including a modified version of Clang front-end, LayerD framework and jQuery Mobile for widgets rendering in the translated source code. A porting aid, not a complete translator but a lot of the dog work is done. Requires one convert to Microsoft tools, however. (via Kevin Marks)

Future is Burked, P2P Currency, Stuff That Matters, and Avatar Widget

  1. James Burke at dConstruct — transcription of his talk. EPIC. I love this man and could listen to him all day long. (via Keith Bolland)
  2. Mechanism Design on Trust Networks (CiteSeerX) — academic paper behind the Ripple Bitcoin-esque open source peer-payment digital currency.
  3. What If Money Was No Object (YouTube) — about finding your way to stuff that matters, and worth it just for the last lines. (via Rowan Simpson)
  4. photobooth-js (GitHub) — BSD-licensed html5 widget that allows users to take their avatar pictures on your site.

Post in Translation, Comic Briefs, Fibre Optics, and Silk Road Financials

  1. Post Lingo — automatically transcribe incoming emails from foreign tongues. (via Brian McConnell)
  2. All Briefs Should Now Be in Comic Book Form — does wonders for mass audience acceptance of the arguments. (via Andy Lester)
  3. Magic Carpet Can Detect and Predict Falls (BBC) — Beneath the carpet is a mesh of optical fibres that detect and plot movement as pressure bends them, changing the light detected at the carpet’s edges. These deflected light patterns help electronics “learn” walking patterns and detect if they are deteriorating, for instance in the elderly. Neat use for fibre optics! (via Sara Winge)
  4. Travelling the Silk Road (PDF) — A measurement analysis of a large anonymous online marketplace [...] A relatively small “core” of about 60 sellers has been present throughout our measurement interval, while the majority of sellers leaves (or goes “underground”) within a couple of weeks of their first appearance. We evaluate the total revenue made by all sellers to approximately USD 1.9 million per month; this corresponds to about USD 143,000 per month in commissions perceived by the Silk Road operators.

Bogan Ipsum, Disassembled and Deconstructed, P2P Commerce, and Android Sensors

  1. Bogan Ipsum — the Australian version of Loren Ipsum. (via Seb Chan)
  2. Microsoft BASIC for 6502 — reverse-engineering magic, this person has RE’d the assembly language for various versions of the BASIC interpreter that shipped on microcomputers in the 80s. This page talks about the changes in each version, the easter eggs, and the hacks. This, kids, is how real programmers do it :)
  3. The Sudden Rise of Peer-to-Peer Commerce (Casey Research) — Today, business are sprouting up around the world based on the idea of connecting individuals directly to each other to trade products and services. While the idea is very much in its infancy still, like the music business at the dawn of Napster, we’re beginning to grasp the potential. Something we are tracking at O’Reilly as well.
  4. The Sensor/itive Side of Android (Luke Wroblewski) — lots of details about sensors in Android, from a Google I/O talk. Sampling rates change between devices. The data has variance and static because it comes from cost-effective components for mobile phones not robust and industry-grade sensors.

Getting your book in front of 160 million users is usually a good thing

"Pirate's Dilemma" author Matt Mason on BitTorrent.

Pirating your own book may seem like an odd promotion strategy, but that's just what Megan Lisa Jones did with her new novel. Matt Mason, author of "The Pirate's Dilemma," says P2P platforms like BitTorrent are a great way to reach audiences and distribute content.

Sensor Trojan, node.js IDE, Quantified Conference, and P2P Streaming

  1. Proof-of-Concept Android Trojan Captures Spoken Credit-Card NumbersSoundminer sits in the background and waits for a call to be placed [...] the application listens out for the user entering credit card information or a PIN and silently records the information, performing the necessary analysis to turn it from a sound recording into a number. Very clever use of sensors for evil! (via Slashdot)
  2. Cloud9 IDE — open source IDE for node.js. I’m using it as I learn node.js, and it’s sweet as, bro.
  3. The Quantified Self Conference — May 28-29 in Mountain View. (via Pete Warden)
  4. Bram Cohen Demos P2P Streaming — the creator of BitTorrent is winding up to release a streaming protocol that is also P2P. (via Hacker News)
