Disk Over Ethernet, Inside Elite, Polar Charts, and R Videos
- Seagate Kinetic Storage — In the words of Geoff Arnold: The physical interconnect to the disk drive is now Ethernet. The interface is a simple key-value object oriented access scheme, implemented using Google Protocol Buffers. It supports key-based CRUD (create, read, update and delete); it also implements third-party transfers (“transfer the objects with keys X, Y and Z to the drive with IP address 220.127.116.11”). Configuration is based on DHCP, and everything can be authenticated and encrypted. The system supports a variety of key schemas to make it easy for various storage services to shard the data across multiple drives.
- Masters of Their Universe (Guardian) — well-written and fascinating story of the creation of the Elite game (one founder of which went on to make the Raspberry Pi). The classic action game of the early 1980s – Defender, Pac Man – was set in a perpetual present tense, a sort of arcade Eden in which there were always enemies to zap or gobble, but nothing ever changed apart from the score. By letting the player tool up with better guns, Bell and Braben were introducing a whole new dimension, the dimension of time.

Visual Arduino Coding, Hardware Iteration, Segmenting Images, and Client-Side Adjustable Data View
- Visually Programming Arduino — good for little minds.
- Rapid Hardware Iteration at Scale (Forbes) — It’s part of the unique way that Xiaomi operates, closely analyzing the user feedback it gets on its smartphones and following the suggestions it likes for the next batch of 100,000 phones. It releases them every Tuesday at noon Beijing time.
- Machine Learning of Hierarchical Clustering to Segment 2D and 3D Images (PLoS One) — We propose an active learning approach for performing hierarchical agglomerative segmentation from superpixels. Our method combines multiple features at all scales of the agglomerative process, works for data with an arbitrary number of dimensions, and scales to very large datasets.
- Kratu — an Open Source client-side analysis framework to create simple yet powerful renditions of data. It allows you to dynamically adjust your view of the data to highlight issues, opportunities and correlations in the data.

Google Code Analysis, Deep Learning, Front-End Workflow, and SICP in JS
- Steve Yegge on GROK (YouTube) — The Grok Project is an internal Google initiative to simplify the navigation and querying of very large program source repositories. We have designed and implemented a language-neutral, canonical representation for source code and compiler metadata. Our data production pipeline runs compiler clusters over all Google’s code and third-party code, extracting syntactic and semantic information. The data is then indexed and served to a wide variety of clients with specialized needs. The entire ecosystem is evolving into an extensible platform that permits languages, tools, clients and build systems to interoperate in well-defined, standardized protocols.
- Deep Learning for Semantic Analysis — When trained on the new treebank, this model outperforms all previous methods on several metrics. It pushes the state of the art in single sentence positive/negative classification from 80% up to 85.4%. The accuracy of predicting fine-grained sentiment labels for all phrases reaches 80.7%, an improvement of 9.7% over bag of features baselines. Lastly, it is the only model that can accurately capture the effect of contrastive conjunctions as well as negation and its scope at various tree levels for both positive and negative phrases.

- 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.

- 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.

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)
