Invisible Data Economy, Hacked Value, Open Algorithms Textbook, and Mobile Testing

  1. Beyond Goods and Services: The Unmeasured Rise of the Data-Driven Economy — excellent points about data as neither good nor service, and how data use goes unmeasured by economists and thus doesn’t influence policy. According to statistics from the Bureau of Economic Analysis, real consumption of ‘internet access’ has been falling since the second quarter of 2011. In other words, according to official U.S. government figures, consumer access to the Internet—including mobile—has been a drag on economic growth for the past year and a half. (via Mike Loukides)
  2. How Crooks Turn Even Crappy Hacked PCs Into Money (Brian Krebs) — show to your corporate IT overlords, or your parents, to explain why you want them to get rid of the Windows XP machines. (via BoingBoing)
  3. Open Data Structures — an open content textbook (Java and C++ editions; CC-BY licensed) on data structures. (via Hacker News)
  4. Mobiforge — test what gets sent back to mobile browsers. This site sends the HTTP headers that a mobile browser would. cf yesterday’s Responsivator. (via Ronan Cremin)

News App, Data Wrangler, Responsive Previews, and Accountable Algorithms

  1. cir.ca — news app for iPhone, which lets you track updates and further news on a given story. (via Andy Baio)
  2. DataWrangler (Stanford) — an interactive tool for data cleaning and transformation. Spend less time formatting and more time analyzing your data. From the Stanford Visualization Group.
  3. Responsivator — see how websites look at different screen sizes.
  4. Accountable Algorithms (Ed Felten) — When we talk about making an algorithmic public process open, we mean two separate things. First, we want transparency: the public knows what the algorithm is. Second, we want the execution of the algorithm to be accountable: the public can check to make sure that the algorithm was executed correctly in a particular case. Transparency is addressed by traditional open government principles; but accountability is different.

Drone Conflict, 3D Scanning Booths, Bitcoin Consensus, and Moar Coders

  1. Beware the Drones (Washington Times) — the temptation to send difficult to detect, unmanned aircraft into foreign airspace with perceived impunity means policymakers will naturally incline towards aggressive use of drones and hyperactive interventionism, leading us to a future that is ultimately plagued by more, not less warfare and conflict. This. Also, what I haven’t seen commented on with the Israeli air force shooting down a (presumably Hezbollah) drone: low cost of drones vs high cost of maintaining an air force to intercept, means this is asymmetric unmanned warfare.
  2. Scanbooth (github) — a collection of software for running a 3D scanning booth. Greg Borenstein said to me, “we need tools to scan and modify before 3D printing can take off.” (via Jeremy Herrman)
  3. Bitcoin’s Value is Decentralization (Paul Bohm) — Bitcoin isn’t just a currency but an elegant universal solution to the Byzantine Generals’ Problem, one of the core problems of reaching consensus in Distributed Systems. Until recently it was thought to not be practically solvable at all, much less on a global scale. Irrespective of its currency aspects, many experts believe Bitcoin is brilliant in that it technically made possible what was previously thought impossible. (via Mike Loukides)
  4. Blue Collar Coder (Anil Dash) — I am proud of, and impressed by, Craigslist’s ability to serve hundreds of millions of users with a few dozen employees. But I want the next Craigslist to optimize for providing dozens of jobs in each of the towns it serves, and I want educators in those cities to prepare young people to step into those jobs. Time for a Massively Multiplayer Online Economy, as opposed to today’s fun economic games of Shave The Have-Nots and Race To The Oligarchy.

Wall Street’s robots are not out to get you

Putting high-frequency trading into perspective.

Technology is critical to today’s financial markets. It’s also surprisingly controversial. In most industries, increasing technological involvement is progress, not a problem. And yet, people who believe that computers should drive cars suddenly become Luddites when…

Objectivist C, Robotrading, Meme Culture, and Mobile-controlled Peripherals

  1. Objectivist C — very clever. In Objectivist-C, each program is free to acquire as many resources as it can, without interference from the operating system. (via Tim O’Reilly)
  2. Zynga and Facebook Stock Oddities (The Atlantic) — signs of robotrading, a reminder that we’re surrounded by algorithms and only notice them when they go awry.
  3. The Final ROFLcon and Mobile’s Impact on Internet Culture (Andy Baio) — These days, memes spread faster and wider than ever, with social networks acting as the fuel for mass distribution. But it’s possible we may see less mutation and remixing in the near future. As Internet usage shifts from desktops and laptops to mobile devices and tablets, the ability to mutate memes in a meaningful way becomes harder.
  4. Oh Mi Bod — I was impressed to learn that one can buy vibrators that can be controlled from an iPhone. Insert iBone joke here. (via Cary Gibson)

Elective Dickery, Probabilistic Data Analysis, Data Cleaning, and SSL Security

  1. Punting on SxSW (Brad Feld) — I came across this old post and thought: if you can make money by being a dick, or make money by being a caring family person, why would you choose to be a dick? As far as I can tell, being a dick is optional. Brogrammers, take note. Be more like Brad Feld, who prioritises his family and acts accordingly.
  2. Probabilistic Structures for Data Mining — readable introduction to useful algorithms and datastructures showing their performance, reliability, and resources trade-off. (via Hacker News)
  3. Dataset — a Javascript library for transforming, querying, manipulating data from different sources.
  4. Many HTTPS Servers are Insecure — 75% still vulnerable to the BEAST attack.

Maximum MySQL, Digital News, Unbiased Mining, and Congressional Clue

  1. How Twitter Stores 250M Tweets a Day Using MySQL (High Scalability) — notes from a talk at the MySQL conference on how Twitter built a high-volume MySQL store.
  2. How The Atlantic Got Profitable With Digital First (Mashable) — Lauf says his team has focused on putting together premium advertising experiences that span print, digital, events and (increasingly) mobile.
  3. Data Mining Without Prejudice — an attempt to measure fit without pre-favouring one type of curve over another.
  4. It Is No Longer OK Not To Know How Congress Works (Clay Johnson) — looking for a specific innovation to try and change the way Washington works by the time Congress votes on SOPA is about as foolish as Steve Jobs trying to diet his way out of having pancreatic cancer.

Bitcoin Banks, Journo Ethics, Android and iOS, and Clever Algorithms

  1. Dan Kaminsky on Bitcoin (Slideshare) — short version: banks are an emergent property as it scales.
  2. Unethical Ventures (All Things D) — astonishing slam on the new venture fund that Michael Arrington (founder of TechCrunch) will be running while still writing for TechCrunch. This could have been a lot cleaner, of course, by Arrington simply resigning from TechCrunch, becoming a VC and perhaps starting a new blog where his agenda is much clearer, from which he could huff and puff away as he does with much entertaining gusto at real and (mostly) imagined slights. There is certainly precedent for VCs blogging, including Fred Wilson, Brad Feld and Ben Horowitz. And, despite my criticisms about ethics, it is clear that Arrington is a talented writer whose unique voice would be even stronger if it was truly seen as separate from what has become a news organization. But because of his obvious need to be the center of attention — requiring the ermine kingmaker mantle and foisting his patented I’m-here-to-tell-it-like-it-is attitude on us all — that appears to be impossible.
  3. An iOS Developer Takes on Android — a very easy to follow comparison of the two platforms from a developer who worked on both and who is carefully not partisan. I hadn’t realized before what an advantage OpenGL confers to the iOS devices. It’s not just for 3D games any more (he says, catching up with 2008).
  4. Clever Algorithms — book of 45 nature-inspired algorithms, code in Ruby.
