- Salesforce Architecture — Our search tier runs on commodity Linux hosts, each of which is augmented with a 640 GiB PCI-E flash drive which serves as a caching layer for search requests. These hosts get their data from a shared SAN array via an NFS file system. Search indexes are stored on the flash drive to enable greater performance for search throughput. Architecture porn.

- Users vs Apps (Tim Bray) — the wrong thing being shared with the wrong people, even once, can ruin a trust relationship forever. Personally, I’m pretty hard-line about this one. I’m currently refusing to update the Android app from my bank, CIBC, because it wants access to my contacts. You know what the right amount of “social” content is in my relationship with my bank? Zero, that’s what.
- MegaPWN (GitHub) — Your MEGA master key is supposed to be a secret, but MEGA or anyone else with access to your computer can easily find it without you noticing. Browser crypto is only as secure as the browser and the code it runs.
- When Smart Homes Get Hacked (Forbes) — Insteon’s flaw was worse in that it allowed access to any one via the Internet. The researchers could see the exposed systems online but weren’t comfortable poking around further. I was — but I was definitely nervous about it and made sure I had Insteon users’ permission before flickering their lights.

- FC4: Persona (Tim Bray) — Mozilla Persona, reminds us just because you’re using a protocol that allows tracking avoidance, that doesn’t mean you’ll get it.
Flexible Layouts, Web Components, Distributed SQL Database, and Reverse-Engineering Dropbox Client
- intention.js — manipulates the DOM via HTML attributes. The methods for manipulation are placed with the elements themselves, so flexible layouts don’t seem so abstract and messy.
- F1: A Distributed SQL Database That Scales — a distributed relational database system built at Google to support the AdWords business. F1 is a hybrid database that combines high availability, the scalability of NoSQL systems like Bigtable, and the consistency and usability of traditional SQL databases. F1 is built on Spanner, which provides synchronous cross-datacenter replication and strong consistency. Synchronous replication implies higher commit latency, but we mitigate that latency by using a hierarchical schema model with structured data types and through smart application design. F1 also includes a fully functional distributed SQL query engine and automatic change tracking and publishing.
- Looking Inside The (Drop)Box (PDF) — This paper presents new and generic techniques, to reverse engineer frozen Python applications, which are not limited to just the Dropbox world. We describe a method to bypass Dropbox’s two factor authentication and hijack Dropbox accounts. Additionally, generic techniques to intercept SSL data using code injection techniques and monkey patching are presented. (via Tech Republic)

- Peruvian Archaeologists Use Drones (Guardian) — Small drones have been helping a growing number of researchers produce three-dimensional models of Peruvian sites instead of the usual flat maps – and in days and weeks instead of months and years.

Approximate Queries, Spreadsheet as Database, China Robot Plans, and Open Source Google App Engine
- blinkdb — The current version of BlinkDB supports a slightly constrained set of SQL-style declarative queries and provides approximate results for standard SQL aggregate queries, specifically queries involving COUNT, AVG, SUM and PERCENTILE and is being extended to support any User-Defined Functions (UDFs). Queries involving these operations can be annotated with either an error bound, or a time constraint, based on which the system selects an appropriate sample to operate on.
- China Plans to Become a Leader in Robotics (Quartz) — The ODCCC too funds high risk research initiatives through the Thousand Talent Project (TTP), a three-year term project with possible extension. The goal of the TTP is to recruit thousands of foreign researchers with strong expertise in hardware and software to help develop innovation in China. There are already more than 100 foreign researchers working in China since 2008, the year TTP started.
- AppScale (GitHub) — open source implementation of Google App Engine.

Backbone Stack, Automating Card Games, Ozzie on PRISM, and Stuff that Matters
- Our Backbone Stack (Pamela Fox) — fascinating glimpse into the tech used and why.
- Automating Card Games Using OpenCV and Python — My vision for an automated version of the game was simple. Players sit across a table on which the cards are laid out. My program would take a picture of the cards and recognize them. It would then generate valid expression that yielded 24, and then project the answer on to the table.
- Ray Ozzie on PRISM — posted on Hacker News (!). In particular, in this world where “SaaS” and “software eats everything” and “cloud computing” and “big data” are inevitable and already pervasive, it pains me to see how 3rd Party Doctrine may now already be being leveraged to effectively gut the intent of U.S. citizens’ Fourth Amendment rights. Don’t we need a common-sense refresh to the wording of our laws and potentially our constitution as it pertains to how we now rely upon 3rd parties? It makes zero sense in a “services age” where granting third parties limited rights to our private information is so basic and fundamental to how we think, work, conduct and enjoy life.

- Larry Brilliant’s Commencement Speech (HufPo) — speaking to med grads, he’s full of purpose and vision and meaning for their lives. His story is amazing. I wish more CS grads were inspired to work on stuff that matters, and cautioned about adding their great minds to the legion trying to solve the problem of connecting you with brands you love.

- Media for Thinking the Unthinkable (Bret Victor) — “Right now, today, we can’t see the thing, at all, that’s going to be the most important 100 years from now.” We cannot see the thing. At all. But whatever that thing is — people will have to think it. And we can, right now, today, prepare powerful ways of thinking for these people. We can build the tools that make it possible to think that thing. (via Matt Jones)
- McKinsey Report on Disruptive Technologies (McKinsey) — the list: Mobile Internet; Automation of knowledge work; Internet of Things; Cloud technology; Advanced Robotics; Autonomous and near-autonomous vehicles; Next-generation genomics; Energy storage; 3D Printing; Advanced Materials; Advanced Oil and Gas exploration and recovery; Renewable energy.
- The Only Public Transcript of the Bradley Manning Trial Will be Produced on a Crowd-Funded Typewriter — [t]he fact that a volunteer stenographer is providing the only comprehensive source of information about such a monumental event is pretty absurd.
