- The Email Game — game mechanics to get you answering email more efficiently. Can’t wait to hear that conversation with corporate IT. “You want us to install what on the Exchange server?” (via Demo Day Wrapup)
- Stratified B-trees and versioning dictionaries — A classic versioned data structure in storage and computer science is the copy-on-write (CoW) B-tree — it underlies many of today’s file systems and databases, including WAFL, ZFS, Btrfs and more. Unfortunately, it doesn’t inherit the B-tree’s optimality properties; it has poor space utilization, cannot offer fast updates, and relies on random IO to scale. Yet, nothing better has been developed since. We describe the `stratified B-tree’, which beats all known semi-external memory versioned B-trees, including the CoW B-tree. In particular, it is the first versioned dictionary to achieve optimal tradeoffs between space, query and update performance. (via Bob Ippolito)
- DisplayCabinet (Ben Bashford) — We embedded a group of inanimate ornamental objects with RFID tags. Totems or avatars that represent either people, products or services. We also added RFID tags to a set of house keys and a wallet. Functional things that you carry with you. This group of objects combine with a set of shelves containing a hidden projector and RFID reader to become DisplayCabinet. (via Chris Heathcote)

ENTRIES TAGGED "email"
In light of recent security snafus, it's worth reviewing the basics of phish detection and prevention.
Major security breaches sometimes lead to an onslaught of phish emails. Here's a handful of simple ways to spot suspect correspondence and avoid traps.
Email Game, Faster B Trees, RFID+Projectors, and Airport Express Broken
An attempt at understanding the deeper meaning of an empty inbox.
I have more than 10,000 unread messages in my inbox, and I think I'm okay with that. But am I missing something by not pursuing "inbox zero"?
Mining implicit data trails makes CRM more effective
One of the richest sources of data exhaust, email logs contain valuable information. When added to data from a traditional CRM, email analytics can provide a much fuller picture of your company's relationships and activity.
Social Mining, Machine Learning, Traffic Patterns, and OpenOffice Autophoenixes
- Digital Mirror Demo (video) — demo of the Digital Mirror tool that analyses relationships. Some very cute visualizations of social proximity and presentation of the things you can learn from email, calendar, etc. (via kgreene on Twitter)
- Free Machine Learning Books — list of free online books from MetaOptimize readers. (via newsycombinator on Twitter)
- Chewie Stats — sweet chart of blog traffic after something went memetic. Interesting for the different qualities of traffic from each site: As one might expect, Reddit users go straight for the punchline and bail immediately. One might assume the the same behavior from Facebook users, but no, among the visitors that hang around, they rank third! Likewise I would have expected MetaFilter readers to hang around and Boing Boing users to quickly move along; but in fact, the opposite is the case. (via chrissmessina on Twitter)
- The Document Foundation — new home of OpenOffice, which has a name change to LibreOffice. I hope this is the start of a Mozilla-like rebirth, as does Matt Asay. (via migueldeicaza on Twitter)
Blue is the color, getting help with email overload.
In the latest edition of Strata Week: Google's introduction of a new search-indexing system highlights an important limitation of MapReduce and Hadoop. Can MapReduce adapt to real-time needs or will others follow Google in creating new architectures for real-time analytics?
notmuch Email, Mobile Processing, Realtime Mocap, and Making Money from Books
- notmuch — commandline tagging and fast search for a mailbox, regardless of which mail client you use.
- Processing for Android — pre-release versions of a Processing for Android devices. Mobile visual programming makes for interesting possibilities.
- Binary Body Double: Microsoft Reveals the Science Behind Project Natal for Xbox 360 — machine learning to recognize poses and render in the game at 30fps. It’s a basic real-time mocap and render.
- The Monetization Paradox — interesting post by Charlie Stross about the quandry of authors. he proposed $9.99 cap on ebooks replaces the high-end $24 hardcover. Not only does it mean less royalties for the authors, it means less money for the publishers — or, more importantly, their marketing divisions. Here’s a hint: if I wanted to spend my time marketing my books I’d have gone into marketing. I’m a writer. Every hour spent on marketing activities is an hour spent not writing. Ditto editing, proofreading, commissioning cover art, and so on. This is what I have publishers for.
Great Mail Feature, Speed Talks, Virtualisation History, Science Literacy
- GMail Labs: Got The Wrong Bob? — When’s the last time you got an email from a stranger asking, “Are you sure you meant to send this to me?” and promptly realized that you didn’t? Looks at the clusters of CCs you send and, if you normally send to Bob X but are trying to send it to Bob Y, asks you “did you mean Bob X?”. This might be the best thing to happen to email since webmail and full-text search–it’s ridiculous how little innovation is happening in email given how widely and heavily it is used.
- Speedgeeks LA at Shopzilla — eight talks about making websites faster. Latency Improvements for PicasaWeb – Gavin Doughtie (Google) – Great tips from a web guru about what makes PicasaWeb fast. Watch for when the slides to more talks become available.
- 10 Years of Virtual Machine Performance Semi-Demystified — fascinating history of virtualisation from someone who worked for VMware. Since 2005, VMware and Xen have gradually reduced the performance overheads of virtualization, aided by the Moore’s law doubling in transistor count, which inexorably shrinks overheads over time. AMD’s Rapid Virtualization Indexing (RVI – 2007) and Intel’s Extended Page Tables (EPT – 2009) substantially improved performance for a class of recalcitrant workloads by offloading the mapping of machine-level pages to Guest OS “physical” memory pages, from software to silicon. In the case of operations that stress the MMU—like an Apache compile with lots of short lived processes and intensive memory access—performance doubled with RVI/EPT. (Xen showed similar challenges prior to RVI/EPT on compilation benchmarks.)
