MapD: Massive Throughput Database Queries with LLVM and GPUs (nvidia) — The most powerful GPU currently available is the NVIDIA Tesla K80 Accelerator, with up to 8.74 teraflops of compute performance and nearly 500 GB/sec of memory bandwidth. By supporting up to eight of these cards per server, we see orders-of-magnitude better performance on standard data analytics tasks, enabling a user to visually filter and aggregate billions of rows in tens of milliseconds, all without indexing.
Why It’s Often Easier to Innovate in China than the US (Bunnie Huang) — We did some research into the legal frameworks and challenges around absorbing gongkai IP into the Western ecosystem, and we believe we’ve found a path to repatriate some of the IP from gongkai into proper open source.
Microservices in Go — tale of rewriting a Ruby monolith as Go microservices. Interesting, though being delivered at Gophercon India suggests the ending is probably not unhappy.
Watch & Wear (John Cross Neumann) — Android watch as predictor of the value and experience of an Apple Watch. I believe this is the true sweet spot for meaningful wearable experiences. Information that matters to you in the moment, but requires no intervention. Wear actually does this extremely well through Google Now. Traffic, Time to Home, Reminders, Friend’s Birthdays, and Travel Information all work beautifully. […] After some real experience with Wear, I think what is more important is to consider what Apple Watch is missing: Google Services. Google Services are a big component of what can make wearing a tiny screen on your wrist meaningful and personal. I wouldn’t be surprised after the initial wave of apps through the app store if Google Now ends up being the killer app for Apple Watch.
Solving 11 Likely Problems In Your Multithreaded Code (Joe Duffy) — a good breakdown of concurrency problems, including lower-level ones than high-level languages expose. But beware. If you try this [accessing variables with synchronisation] on a misaligned memory location, or a location that isn’t naturally sized, you can encounter a read or write tearing. Tearing occurs because reading or writing such locations actually involves multiple physical memory operations. Concurrent updates can happen in between these, potentially causing the resultant value to be some blend of the before and after values.
Obama Sharply Criticizes China’s Plans for New Technology Rules (Reuters) — In an interview with Reuters, Obama said he was concerned about Beijing’s plans for a far-reaching counterterrorism law that would require technology firms to hand over encryption keys, the passcodes that help protect data, and install security “backdoors” in their systems to give Chinese authorities surveillance access. Goose sauce is NOT gander sauce! NOT! Mmm, delicious spook sauce.
Bruce Sterling on Disruption — If more computation, and more networking, was going to make the world prosperous, we’d be living in a prosperous world. And we’re not. Obviously we’re living in a Depression. Slow first 25% but then it takes fire and burns with the heat of a thousand Sun Microsystems flaming out. You must read this now.
The Matasano Crypto Challenges (Maciej Ceglowski) — To my delight, though, I was able to get through the entire sequence. It took diligence, coffee, and a lot of graph paper, but the problems were tractable. And having completed them, I’ve become convinced that anyone whose job it is to run a production website should try them, particularly if you have no experience with application security. Since the challenges aren’t really documented anywhere, I wanted to describe what they’re like in the hopes of persuading busy people to take the plunge.
