Google’s Philosopher — interesting take on privacy. Now that the mining and manipulation of personal information has spread to almost all aspects of life, for instance, one of the most common such questions is, “Who owns your data?” According to Floridi, it’s a misguided query. Your personal information, he argues, should be considered as much a part of you as, say, your left arm. “Anything done to your information,” he has written, “is done to you, not to your belongings.” Identity theft and invasions of privacy thus become more akin to kidnapping than stealing or trespassing. Informational privacy is “a fundamental and inalienable right,” he argues, one that can’t be overridden by concerns about national security, say, or public safety. “Any society (even a utopian one) in which no informational privacy is possible,” he has written, “is one in which no personal identity can be maintained.”
S-1 for a Bitcoin Trust (SEC) — always interesting to read through the risks list to see what’s there and what’s not.
Computationally Modelling Human Emotion (ACM) — our work seeks to create true synergies between computational and psychological approaches to understanding emotion. We are not satisfied simply to show our models “fit” human data but rather seek to show they are generative in the sense of producing new insights or novel predictions that can inform understanding. From this perspective, computational models are simply theories, albeit more concrete ones that afford a level of hypothesis generation and experimentation difficult to achieve through traditional theories.
Opinion Formation Models on a Gradient (PLoSONE) — Many opinion formation models embedded in two-dimensional space have only one stable solution, namely complete consensus, in particular when they implement deterministic rules. In reality, however, deterministic social behavior and perfect agreement are rare – at least one small village of indomitable Gauls always holds out against the Romans. […] In this article we tackle the open question: can opinion dynamics, with or without a stochastic element, fundamentally alter percolation properties such as the clusters’ fractal dimensions or the cluster size distribution? We show that in many cases we retrieve the scaling laws of independent percolation. Moreover, we also give one example where a slight change of the dynamic rules leads to a radically different scaling behavior.
Governance for the New Class of Worker (Matt Webb) — there is a new class of worker. They’re not inside the company – not benefiting from job security or healthcare – but their livelihoods in large part dependent on it, the transaction cost of moving to a competitor deliberately kept high. Or the worker is, without seeing any of the upside of success, taking on the risk or bearing the cost of the company’s expansion and operation.
Hidden Code in Your Chipset (Slideshare) — there’s a processor that supervises your processor, and it’s astonishingly fully-featured (to the point of having privileged access to the network and being able to run Java code).
On Nerd Entitlement — Privilege doesn’t mean you don’t suffer. The best part of 2014 was the tech/net feminist consciousness-raising/uprising. That’s probably the wrong label for it, but bullshit is being called that was ignored years ago. I think we’ve collectively found the next thing we fix that future generations will look back on us and wonder why it went unremarked-upon for so long.
Understanding Paxos — a simple introduction, with animations, to one of the key algorithms in distributed systems.
From Gongkai to Open Source (Bunnie Huang) — The West has a “broadcast” view of IP and ownership: good ideas and innovation are credited to a clearly specified set of authors or inventors, and society pays them a royalty for their initiative and good works. China has a “network” view of IP and ownership: the far-sight necessary to create good ideas and innovations is attained by standing on the shoulders of others, and as such there is a network of people who trade these ideas as favors among each other. In a system with such a loose attitude toward IP, sharing with the network is necessary as tomorrow it could be your friend standing on your shoulders, and you’ll be looking to them for favors. This is unlike the West, where rule of law enables IP to be amassed over a long period of time, creating impenetrable monopoly positions. It’s good for the guys on top, but tough for the upstarts.
Ramble About Bitcoin (Matt Webb) — the meta I’m trying to figure out is: when you spot that one of these deep value chains is at the beginning of a big reconfiguration, what do you do? How do you enter it as a small business? How, as a national economy, do you help it along and make sure the transition happens healthily?
Clustering Bitcoin Accounts Using Heuristics (O’Reilly Radar) — In theory, a user can go by many different pseudonyms. If that user is careful and keeps the activity of those different pseudonyms separate, completely distinct from one another, then they can really maintain a level of, maybe not anonymity, but again, cryptographically it’s called pseudo-anonymity. […] It turns out in reality, though, the way most users and services are using bitcoin, was really not following any of the guidelines that you would need to follow in order to achieve this notion of pseudo-anonymity. So, basically, what we were able to do is develop certain heuristics for clustering together different public keys, or different pseudonyms.
A Primer on Hardware Security: Models, Methods, and Metrics (PDF) — Camouflaging: This is a layout-level technique to hamper image-processing-based extraction of gate-level netlist. In one embodiment of camouflaging, the layouts of standard cells are designed to look alike, resulting in incorrect extraction of the netlist. The layout of nand cell and the layout of nor cell look different and hence their functionality can be extracted. However, the layout of a camouflaged nand cell and the layout of camouflaged nor cell can be made to look identical and hence an attacker cannot unambiguously extract their functionality.
Prompter: A Domain-Specific Language for Versu (PDF) — literally a scripting language (you write theatrical-style scripts, characters, dialogues, and events) for an inference engine that lets you talk to characters and have a different story play out each time.
Popular Chinese Android Smartphone Backdoored By Manufacturer — Coolpad is the third largest smartphone builder in China, and ranks sixth worldwide with 3.7 percent global market share. It trails only Lenovo and Xiaomi in China and is the leader of China’s 4G market with 16 percent market share. Coolpad outsells Samsung and Apple in China, and has said it plans to expand globally with a goal of 60 million phones worldwide. For now, its high-end Halo Dazen phones are the only ones containing the backdoor, Palo Alto said. Backdoor enabled installation of other apps, dial numbers, send messages, and report back to the mothership. The manufacturer even ran the command-and-control nodes for the malware.
USB Driveby — dongle that plugs into USB, and tries to root the box. Specifically, when you normally plug in a mouse or keyboard into a machine, no authorization is required to begin using them. The devices can simply begin typing and clicking. We exploit this fact by sending arbitrary keystrokes meant to launch specific applications (via Spotlight/Alfred/Quicksilver), permanently evade a local firewall (Little Snitch), install a reverse shell in crontab, and even modify DNS settings without any additional permissions.
Dissent — an anonymous communication substrate intended primarily for applications built on a broadcast communication model: for example, bulletin boards, wikis, auctions, or voting. Users of an online group obtain cryptographic guarantees of sender and receiver anonymity, message integrity, disruption resistance, proportionality, and location hiding. And a pony.
USB Armory — another Linux-on-a-stick, but this one has some nifty dimensions and security applications in mind.
Who’s the Boss? — The Elf on the Shelf essentially teaches the child to accept an external form of non-familial surveillance in the home when the elf becomes the source of power and judgment, based on a set of rules attributable to Santa Claus. Excellent deconstruction of ludic malware. (via Washington Post)
Bezos on Time (Business Insider) — Where you are going to spend your time and your energy is one of the most important decisions you get to make in life. We all have a limited amount of time, and where you spend it and how you spend it is just an incredibly levered way to think about the world. This (he says at 9 p.m. in the office, in a different city from his family!).
The Many Facades of DRM (PDF) — Modular software systems are designed to be broken into independent pieces. Each piece has a clear boundary and well-defined interface for ‘hooking’ into other pieces. Progress in most technologies accelerates once systems have achieved this state. But clear boundaries and well-defined interfaces also make a technology easier to attack, break, and reverse-engineer. Well-designed DRMs have very fuzzy boundaries and are designed to have very non-standard interfaces. The examples of the uglified DRM code are inspiring.
DPDK — a set of libraries and drivers for fast packet processing […] to: receive and send packets within the minimum number of CPU cycles (usually less than 80 cycles); develop fast packet capture algorithms (tcpdump-like); run third-party fast path stacks.
Clearing the Air Around Tor (Quinn Norton) — Occasionally the stars align between spooks and activists and governments and anarchists. Tor, like a road system or a telephone network or many pieces of public infrastructure, is useful to all of these people and more (hence the debate on child pornographers and drug markets) because it’s just such a general architecture of encryption. The FBI may want Tor to be broken, but I promise any spies who are counting on it for mission and life don’t.
Offline Cookbook — how Chrome intends to solve the offline problem in general. I hope it works and takes off because offline is the bane of this webapp-user’s life.
The Pirate Bay, Down Forever? — As a big fan of the KLF I once learned that it’s great to burn great things up. At least then you can quit while you’re on top.
Luigi (Github) — a Python module that helps you build complex pipelines of batch jobs. It handles dependency resolution, workflow management, visualization, etc. It also comes with Hadoop support built in. (via Asana engineering blog)
