Four Short Links: 24 August 2009

Distributed Version Control Systems, Ideas Tracking, OO Survey Results, New Barcodes

  1. Making Sense of Revision Control Systems (ACM Queue) — good introduction to the subject from Bryan O’Sullivan, author of Mercurial: The Definitive Guide (aka Distributed Revision Control with Mercurial) that covers Subversion, Mercurial, and git. Under the distributed view of revision control, every commit is potentially a branch of its own. If Bob and Alice start from the exact same view of history, and each one makes a commit, they have already created a tiny anonymous fork in the history of the project. Neither will know about this until one pulls the other’s changes in, at which point they will have to merge with them. These tiny branches and merges are so frequent with Mercurial and Git that users of these tools look at branching and merging in a very different way from Subversion users. The parallel and branchy nature of a project’s development is clearly visible in its history, making it obvious who made which changes when, and exactly which other changes theirs were based upon.
  2. Ideas Are AwesomeIdeas Are Awesome is a web culture aggregator tracking emerging marketing, design, and technology memes. We are currently tracking: simplify, empower, give, inspire, connect, adapt. (via cheeky_geeky on Twitter)
  3. OO Concepts Survey ResultThere were 3785 people who completed the survey. These charts show the proportion who gave the different possible responses for each question. If you’re an OO programmer, use this to determine how aberrant your practices are (hint: most people are neither zealous nor consistent).
  4. Bokodea new camera based interaction solution where an ordinary camera can detect small optical tags from a relatively large distance. Current optical tags, such as barcodes, must be read within a short range and the codes occupy valuable physical space on products. We present a new low-cost optical design so that the tags can be shrunk to 3mm visible diameter, and unmodified ordinary cameras several meters away can be set up to decode the identity plus the relative distance and angle. The design exploits the bokeh effect of ordinary cameras lenses, which maps rays exiting from an out of focus scene point into a disk like blur on the camera sensor. (via waxy)

Trends, Graffiti, Games, and Streaming Video

  1. Trending Topics — full source code for trendingtopics.org, Wikipedia trend analysis. Rails app running on the Cloudera Hadoop Distribution on EC2. (via mattb on Delicious)
  2. Graffiti from Pompeii — I can’t help but read these as Tweets. Herculaneum (on the exterior wall of a house); 10619: Apollinaris, the doctor of the emperor Titus, defecated well here (see also olde style Twitter) (via OvidPerl on Twitter)
  3. Online Games Dominate Beijing Startonomics — presentations from sessions on Chinese game business at Startonomics conference. Though there are many differences between the US and China games market, the one that stands out most is China’s ability to massively monetize games. Tencent, a leading Chinese web portal, social network and game developer, famously announced revenue of over $1 billion earlier this year, much of it coming from their avatar service.

  4. Ustream’s Audience for Apple iPhone Announcement Greater Than Cable News — Ustream is amazing, you can take a consumer handycam and video broadcast live to a greater audience than many TV shows get.

Twitter Approval Matrix

Twitter Approval Matrix

This matrix shows four quadrants used to describe tastes found on Twitter, or related sites such as hashtag.org, tweestats.com, etc. The Y-axis is partly analytical and shows popularity (mostly through scraped numbers) or perceived popularity (in the future nominated by you). The other part of the grid is more curated and subjective. The X-axis has been plotted based on my personal opinion.

OFF=ON Trend and Ubiquitous Computing

The good folks at trendwatching.com have a new trend report up, called OFF=ON. In their words: More and more, the offline world (a.k.a. the real world, meatspace or atom-arena) is adjusting to and mirroring the increasingly dominant online world, from tone of voice to product development to business processes to customer relationships. They're absolutely right, the signs are right…

Radar Theme: Art and Technology

[This is part of a series of posts that briefly describe the trends that we're currently tracking here at O'Reilly] Art is emotion hacking, intended to provoke or illuminate rather than profit. Artists play on the boundaries of new materials, new modes of interaction, new technologies. Often what they build can inspire or inform useful and commercial hacking. Watchlist: Natalie…

Radar Theme: Materials Science

[This is part of a series of posts that briefly describe the trends that we're currently tracking here at O'Reilly] New materials follow a curve: initially expensive and so used by R&D only, but many eventually become mass-produced and cheap and so enable mainstream applications. By tracking new materials with interesting possibilities, we can be ahead of the mass-manufacturing curve….
