Better UIs, Dot Tricks, UAV Camera, and Writing Interactive Fiction

  1. Good UI — easily digested tips for improving UIs. (via BERG London)
  2. Mapping Millions of Dots — tips like The other thing that goes along with this brightness scaling is to draw fewer dots at lower zoom levels. By the time you get most of a continent on the screen, the dots are so much smaller than pixels and there are so many of them to draw, that it looks the same and is much faster if you draw half as many dots at twice the brightness apiece. (via Flowing Data)
  3. 118g 10x Zoom Camera for Drones — little less than 800×600 resolution. (via DIY Drones)
  4. Creating Interactive Fiction with Inform7 (Amazon) — all you need to write your own Zork, or even do better. With foreword by my hero (I squee like fanboy when I remember meeting him at the first Foo Camp) Don Woods. Yeah, Colossal Cave Adventure Don Woods. WIN. (via Marshall Tenner Winter)

Good Dev, User-Hostile Patterns, Patent Victories, and Drone History

  1. What to Look For in Software Dev (Pamela Fox) — It’s important to find a job where you get to work on a product you love or problems that challenge you, but it’s also important to find a job where you will be happy inside their codebase – where you won’t be afraid to make changes and where there’s a clear process for those changes.
  2. The Slippery Slope to Dark Patterns — demonstrates and deconstructs determinedly user-hostile pieces of software which deliberately break Nielsen’s usability heuristics to make users agree to things they rationally wouldn’t.
  3. Victory Lap for Ask Patents (Joel Spolsky) — story of how a StackExchange board on patents helped bust a bogus patent. It’s crowdsourcing the prior art, and Joel shows how easy it is.
  4. The World as Fire-Free Zone (MIT Technology Review) — data analysis to identify “signature” of terrorist behaviour, civilian deaths from strikes in territories the US has not declared war on, empty restrictions on use. Again, it’s a test that, by design, cannot be failed. Good history of UAVs in warfare and the blowback from their lax use. Quoting retired General Stanley McChrystal: The resentment caused by American use of unmanned strikes … is much greater than the average American appreciates. They are hated on a visceral level, even by people who’ve never seen one or seen the effects of one.

Security Sensor, Mobile Speed, Rate Limiting, and Self-Assembling Drone

  1. Canary (IndieGogo) — security sensor with video, motion, temperature, microphone, speaker, accelerometer, and smartphone remote control.
  2. Page Speed is Only The Beginning73% of mobile internet users say they’ve encountered Web pages that are too slow. A 1 second delay can result in a 7% reduction in conversions.
  3. Rate Limiting and Velocity Checking (Jeff Atwood) — I was shocked how little comprehensive information was out there on rate limiting and velocity checking for software developers, because they are your first and most important line of defense against a broad spectrum of possible attacks. It’s amazing how many attacks you can mitigate or even defeat by instituting basic rate limiting. (via Alex Dong)
  4. Self-Assembling Multicopter (DIY Drones) — The true accomplishment of this research is that there is not one robot in control – each unit in itself decides what actions to take to keep the group in the air in what’s known as Distributed Flight Array. (via Slashdot)

Spatial Verbs, Open Source Malaria, Surviving Management, and Paper-like UAV

  1. Operative Design — A catalogue of spatial verbs. (via Adafruit)
  2. Open Source Malaria — open science drug discovery.
  3. Surviving Being (Senior) Tech Management (Kellan Elliott-McCrea) — Perspective is the thin line between a challenging but manageable problem, and chittering balled up in the corner.
  4. Disposable UAVs Inspired by Paper Planes (DIY Drones) — The first design, modeled after a paper plane, is created from a cellulose sheet that has electronic circuits ink-jet printed directly onto its body. Once the circuits have been laid on the plane’s frame, the craft is exposed to a UV curing process, turning the planes body into a flexible circuit board. These circuits are then connected to the planes “avionics system”, two elevons attached to the rear of the craft, which give the UAV the ability to steer itself to its destination.

Binary Instrumentation, Drone-Laser Warfare, Rocking the Rewrite, and Quantified Inbox

  1. Pin: A Dynamic Binary Instrumentation Toola dynamic binary instrumentation framework for the IA-32 and x86-64 instruction-set architectures that enables the creation of dynamic program analysis tools. Some tools built with Pin are Intel Parallel Inspector, Intel Parallel Amplifier and Intel Parallel Advisor. The tools created using Pin, called Pintools, can be used to perform program analysis on user space applications in Linux and Windows. As a dynamic binary instrumentation tool, instrumentation is performed at run time on the compiled binary files. Thus, it requires no recompiling of source code and can support instrumenting programs that dynamically generate code.
  2. Lasers Bringing Down Drones (Wired) — I’ve sat on this for a while, but it is still hypnotic. Autonomous attack, autonomous defence. Pessimist: we’ll be slaves of the better machine learning algorithm. Optimist: we can make love while the AIs make war.
  3. Advice on Rewriting It From Scratch — every word is true. Over my career, I’ve come to place a really strong value on figuring out how to break big changes into small, safe, value-generating pieces. It’s a sort of meta-design — designing the process of gradual, safe change.
  4. Creating Gmail Inbox Statistics Reportsshows how to setup gmail to send you an email at the beginning of each month showing statistics for the previous month, such as the number of emails you received, the top 5 to whom you sent email, the top 5 from whom you received email, charts on your daily usage.

Social Science, YAKVS, Open Source Mail, and Tesla Coil and Quadrocopter Fun

  1. The Effect of Group Attachment and Social Position on Prosocial Behavior (PLoSone) — notable, in my mind, for We conducted lab-in-the-field experiments involving 2,597 members of producer organizations in rural Uganda. cf the recently reported “rich are more selfish than poor” findings, which (like a lot of behavioural economics research) studies Berkeley undergrads who weren’t smart enough to figure out what was being studied.
  2. elephanta HTTP key/value store with full-text search and fast queries. Still a work in progress.
  3. geary (IndieGoGo) — a beautiful modern open-source email client. Found this roughly the same time as elasticinbox open source, reliable, distributed, scalable email store. Open source email action starting?
  4. The Faraday Copter (YouTube) — Tesla coil and quadrocopter madness. (via Jeff Jonas)

Drone Journalism, DNS Sniffing, E-Book Lending, and Structured Data Server

  1. Drone Journalismtwo universities in the US have already incorporated drone use in their journalism programs. The Drone Journalism Lab at the University of Nebraska and the Missouri Drone Journalism Program at the University of Missouri both teach journalism students how to make the most of what drones have to offer when reporting a story. They also teach students how to fly drones, the Federal Aviation Administration (FAA) regulations and ethics.
  2. passivednsA network sniffer that logs all DNS server replies for use in a passive DNS setup.
  3. IFLA E-Lending Background Paper (PDF) — The global dominance of English language eBook title availability reinforced by eReader availability is starkly evident in the statistics on titles available by country: in the USA: 1,000,000; UK: 400,000; Germany/France: 80,000 each; Japan: 50,000; Australia: 35,000; Italy: 20,000; Spain: 15,000; Brazil: 6,000. Many more stats in this paper prepared as context for the International Federation of Library Associations.
  4. The god Architecturea scalable, performant, persistent, in-memory data structure server. It allows massively distributed applications to update and fetch common data in a structured and sorted format. Its main inspirations are Redis and Chord/DHash. Like Redis it focuses on performance, ease of use and a small, simple yet powerful feature set, while from the Chord/DHash projects it inherits scalability, redundancy, and transparent failover behaviour.

Equity of Access, Smartphone Rare Earths, Nanoquadrocopter, and Macmillan Expands in Open Science

  1. Myth of the Free Internet (The Atlantic) — equity of access is an important issue, but this good point is marred by hanging it off the problematic (beer? speech? downloads?) “free”. I’m on the council of InternetNZ whose mission is to protect and promote the open and uncaptureable Internet. (A concept so good we had to make up a word for it)
  2. Periodic Table of the SmartPhone (PDF, big) — from Scientific American article on Rare Earth Minerals in the Smartphone comes a link to this neat infographic showing where rare earth elements are used in the iPhone. (via Om Malik)
  3. CrazyFlie Nano Preorders19g, 9cm x 9cm, 20min charge time for 7m flight time on this nano-quadrocopter. (via Wired)
  4. Changing Scientific Publishing (The Economist) — Nature buys an alternative journal publisher (30 titles in 14 scientific fields), which comes with an 80k-member social network for scientists. Macmillan are a clever bunch. (O’Reilly runs Science Foo Camp with Macmillan’s Digital Sciences and Google)

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)

Cheap Attack Drones, Truth Filters, Where Musicians Make Money, and Dynamic Pricing From Digitized Analogue Signals

  1. Chinese Attack UAV (Alibaba) — Small attack UAV is characterized with small size, light weight, convenient carrying, rapid outfield expansion procedure, easy operation and maintenance; the system only needs 2-3 operators to operate, can be carried by surveillance personnel to complete the attack mission. (via BoingBoing)
  2. TruthTeller Prototype (Washington Post) — speech-to-text, then matches statements against known facts to identify truth/falsehoods. Still a prototype but I love that, in addition to the Real Time Coupon Specials From Hot Singles Near You mobile advertising lens, there might be a truth lens that technology helps us apply to the world around us.
  3. Money from Music: Survey Evidence on Musicians’ Revenue and Lessons About Copyright Incentives — 5,000 American musicians surveyed, For most musicians, copyright does not provide much of a direct financial reward for what they are producing currently. The survey findings are instead consistent with a winner-take-all or superstar model in which copyright motivates musicians through the promise of large rewards in the future in the rare event of wide popularity. This conclusion is not unfamiliar, but this article is the first to support it with empirical evidence on musicians’ revenue. (via TechDirt)
  4. Max Levchin’s DLD13 KeynoteI believe the next big wave of opportunities exists in centralized processing of data gathered from primarily analog systems. [...] There is also a neat symmetry to this analog-to-digtail transformation — enabling centralization of unique analog capacities. As soon as the general public is ready for it, many things handled by a human at the edge of consumption will be controlled by the best currently available human at the center of the system, real time sensors bringing the necessary data to them in real time.
