Caching Pages, Node NLP, Digital Native are Clueless, and Wal-Mart Loves Your Calendar

  1. Cache Them If You Can (Steve Souders) — the percentage of resources that are cacheable has increased 4% during the past year. Over that same time the number of requests per page has increased 12% and total transfer size has increased 24%.
  2. Natural — MIT-licensed general natural language facility for nodejs. Tokenizing, stemming, classification, phonetics, tf-idf, WordNet, string similarity, and some inflection are currently supported. (via Javascript Weekly)
  3. How Millennials SearchStatistically significant findings suggest that millennial generation Web searchers proceed erratically through an information search process, make only a limited attempt to evaluate the quality or validity of information gathered, and may perform some level of ‘backfilling’ or adding sources to a research project before final submission of the work. Never let old people tell you that “digital natives” actually know what they’re doing.
  4. Walmart Buys A Facebook App for Calendar Access (Ars Technica) — The Social Calendar app and its file of 110 million birthdays and other events, acquired from Newput Corp., will give Walmart the ability to expand its efforts to dig deeper into the lives of customers. Interesting to think that by buying a well-loved app, a company could get access to your Facebook details whether you Like them or not.

Data Journalism, Fast Web Servers, Android App Inventor, and Daily Deal Dirt

  1. S0rce — gorgeous infographics. They purport to let you Think for Yourself which is bald-faced bullshit: the choice of which data to present, and the invisible collection and curation practices behind the data, is the choice of what story to tell and what it will say. That said, it’s wonderful to see the numbers (and they are attributed) behind the Republican Primary and Copyright and Piracy Legislation.
  2. Modern HTTP Servers are Fast — I remember when the best web engineering in the world would still fall over if a box got more than 10 hits/second. Yes, yes, I’m writing this on my grandpa box. Check out the hardware specs of the box these numbers are from.
  3. MIT App Inventor — web-based app designer. Does not appear to be open source. There is no long-term sustainability for this kind of development environment: when MIT decide “nah screw it, not going to run this any more” or “hmm, maybe we’ll charge for it”, you’re boned–you can download the “source” to your app in a zip file but AppInventor is the only dev environment which can consume it. I hope it’ll become the awesome and easy dev environment that Android needs, but I hope they prevent it from being a dead end.
  4. Daily Deals: Prediction, Social Diffusion, and Reputational Ramificationswe consider the effects of daily deals on the longer-term reputation of merchants, based on their Yelp reviews before and after they run a daily deal. Our analysis shows that while the number of reviews increases significantly due to daily deals, average rating scores from reviewers who mention daily deals are 10% lower than scores of their peers on average.
