ENTRIES TAGGED "crypto"
Android Crypto, Behaviour Trees, Complexity Cheatsheet, and Open Source Game Theory
- An Empirical Study of Cryptographic Misuse in Android Applications (PDF) We develop program analysis techniques to automatically check programs on the Google Play marketplace, that 10,327 out of 11,748 applications that use cryptographic APIs (88% overall) make at least one mistake.
- Introduction to Behaviour Trees — DAGs with codey nodes. Behavior trees replace the often intangible growing mess of state transitions of finite state machines (FSMs) with a more restrictive but also more structured traversal defining approach.
- P vs NP Cheat Sheet — the space and time Big-O complexities of common algorithms used in Computer Science.
- Game Theory and Network Effects in Open Source — delicate balance of incentives go into the decision for companies to Open Source or close source their software in the midst of discussions of Nash Equilibria. Enjoy.
NSA Crypto, Web Traps, Learn by Doing, and Distributed Testing
- On the NSA — intelligent unpacking of what the NSA crypto-weakening allegations mean.
- Overview of the 2013 OWASP Top 10 — rundown of web evil to avoid. (via Ecryption)
- Easy 6502 — teaches 6502 assembler, with an emulator built into the book. This is what programming non-fiction books will look like in the future.
- Kochiku — distributing automated test suites for faster validation in continuous integration.
Google Play Services, Self-Signed Kernels, Visualising Scientific Papers, and New Microcontroller
- How Google’s Defragging Android (Ars Technica) — Android’s becoming a pudgy microkernel for the Google Play Services layer that’s in userland, closed source, and a way to bypass carriers’ lag for upgrades.
- Booting a Self-Signed Linux Kernel (Greg Kroah-Hartman) — procedures for how to boot a self-signed Linux kernel on a platform so that you do not have to rely on any external signing authority.
- Paperscape — A map of scientific papers from the arXiv.
- Trinket — Adafruit’s latest microcontroller board. Small but perfectly formed.
Big Diner, Fab Future, Browser Crypto, and STEM Crisis Questioned
- In Search of the Optimal Cheeseburger (Hilary Mason) — playing with NYC menu data. There are 5,247 cheeseburgers you can order in Manhattan. Her Ignite talk from Ignite NYC15.
- James Burke Predicting the Future — spoiler: massive disruption from nano-scale personal fabbing.
- The STEM Crisis is a Myth (IEEE Spectrum) — Every year U.S. schools grant more STEM degrees than there are available jobs. When you factor in H-1B visa holders, existing STEM degree holders, and the like, it’s hard to make a case that there’s a STEM labor shortage.
- MegaPWN (GitHub) — Your MEGA master key is supposed to be a secret, but MEGA or anyone else with access to your computer can easily find it without you noticing. Browser crypto is only as secure as the browser and the code it runs.
- When Smart Homes Get Hacked (Forbes) — Insteon’s flaw was worse in that it allowed access to any one via the Internet. The researchers could see the exposed systems online but weren’t comfortable poking around further. I was — but I was definitely nervous about it and made sure I had Insteon users’ permission before flickering their lights.
- A Stick Figure Guide to Advanced Encryption Standard (AES) — exactly what it says.
Cryptanalysis Tools, Renaissance Hackers, MakerCamp Review, and Visual Regressions
- bletchley (Google Code) — Bletchley is currently in the early stages of development and consists of tools which provide: Automated token encoding detection (36 encoding variants); Passive ciphertext block length and repetition analysis; Script generator for efficient automation of HTTP requests; A flexible, multithreaded padding oracle attack library with CBC-R support.
- Hackers of the Renaissance — Four centuries ago, information was as tightly guarded by intellectuals and their wealthy patrons as it is today. But a few episodes around 1600 confirm that the Hacker Ethic and its attendant emphasis on open-source information and a “hands-on imperative” was around long before computers hit the scene. (via BoingBoing)
- Maker Camp 2013: A Look Back (YouTube) — This summer, over 1 million campers made 30 cool projects, took 6 epic field trips, and met a bunch of awesome makers.
- huxley (Github) — Watches you browse, takes screenshots, tells you when they change. Huxley is a test-like system for catching visual regressions in Web applications. (via Alex Dong)
Toxic Behaviour, Encryption Deception, Foursquare Strategy, and Problem-First Learning
- Toxic Behaviour — only 5% of toxic behavior comes from toxic people; 77% of it comes from people who are usually good.
- More Encryption Is Not The Solution (Poul-Henning Kamp) — To an intelligence agency, a well-thought-out weakness can easily be worth a cover identity and five years of salary to a top-notch programmer. Anybody who puts in five good years on an open source project can get away with inserting a patch that “on further inspection might not be optimal.”
- On Location With Foursquare (Anil Dash) — Foursquare switched from primarily being concerned with the game-based rewards around engagement and the recording of people’s whereabouts to a broader mission that builds on that base to be about location as a core capability of the Internet.
- The Flipped Flipped Classroom — the “exploration first” model is a better way to learn. You cannot have the answers before you think of the questions. (via Karl Fisch)
Startups Class, Container Deployment, Cryptopocalypse, and Program Design
- EP245 Downloads — class materials from the Udacity “How to Build a Startup” course.
- scrz.io — easy container deployment.
- The Factoring Dead: Preparing for the Cryptopocalypse — how RSA and Diffie-Helman crypto might be useless in the next few years.
- How to Design Programs — 2ed text is a work-in-progress.
Better Crypto, NukeViz, Weed Economics, and Ethics of Prediction
- Applied Practical Cryptography — technical but readable article with lots of delicious lines. They’re a little magical, in the same sense that ABS brakes were magical in the 1970s and Cloud applications share metal with strangers, and thus attackers, who will gladly spend $40 to co-host themselves with a target and The conservative approach is again counterintuitive to developers, to whom hardcoding anything is like simony.
- Nukemap — interactive visualization of the fallout damage from a nuclear weapon. Now we can all be the scary 1970s “this is what it would look like if [big town] were nuked” documentaries that I remember growing up with. I love interactives for learning the contours of a problem, and making it real and personal in a way that a static visualization cannot. WIN. See also the creator’s writeup.
- Legalising Weed — Chuck, a dealer who switched from selling weed in California to New York and quadrupled his income, told WNYC, “There’s plenty of weed in New York. There’s just an illusion of scarcity, which is part of what I’m capitalizing on. Because this is a black market business, there’s insufficient information for customers.” Invisible economies are frequently inefficient, disrupted by moving online and made market-sense efficient.
- Can Software That Predicts Crime Pass Constitutional Muster? (NPR) — “I think most people are gonna defer to the black box,” he says. “Which means we need to focus on what’s going into that black box, how accurate it is, and what transparency and accountability measures we have [for] it.”
