- Web Design: The First 100 Years (Maciej Ceglowski) — There’s a William Gibson quote that Tim O’Reilly likes to repeat: “the future is here; it’s just not evenly distributed yet.” O’Reilly takes this to mean that if we surround ourselves with the right people, it can give us a sneak peek at coming attractions. I like to interpret this quote differently, as a call to action. Rather than waiting passively for technology to change the world, let’s see how much we can do with what we already have. Let’s reclaim the Web from technologists who tell us that the future they’ve imagined is inevitable, and that our role in it is as consumers.
- Comparing Cassandra Write Performance on Google Compute Engine and AWS — tl;dr – We achieved better Cassandra performance on GCE vs. Amazon, at close to half the cost. Also interesting for how they built the benchmark.
- The Scammy Underground World of Kindle eBooks — The biggest issue here isn’t that scammers are raking in cash from low-quality content; it’s that Amazon is allowing this to happen. Publisher brand value is the reliable expectation that buyers have of the book quality. Amazon’s publishing arm is spending the good brand value built by its distribution arm.
- Empire — a 12-factor-compatible, Docker-based container cluster built on top of Amazon’s robust EC2 Container Service (ECS), complete with a full-featured command line interface. Open source.
"open source" entries
From Pluto flybys to open source in the enterprise to engineering the future, here are key highlights from OSCON 2015.
Experts and advocates from across the open source world assembled in Portland, Ore., this week for OSCON 2015. Below you’ll find a handful of keynotes and interviews from the event that we found particularly notable.
Cracking open the IoT
In an interview at OSCON, Alasdair Allan, director at Babilim Light Industries, talked about the data coming out of the New Horizons Pluto flyby, the future of “personal space programs,” and the significance of Bluetooth LE to the Internet of Things:
Now that all the smartphones have Bluetooth LE — or at least the modern ones, there is a very easy way to produce low-power devices (wearables, embedded sensors) that anyone can access with a smartphone. … It’s a real lever to drive the Internet of Things forward, and you’re seeing a lot of the progress in the Internet of Things, a lot of the innovation, is happening — especially in Kickstarter — around BLE devices.
Finding new ways to shrink disk space for storing partitionable data.
Register for the free webcast, “Extending Cassandra with Doradus OLAP for High Performance Analytics,” which will be held July 29 at 9 a.m. PT.
Engineers at Dell were developing customer apps when they found that the query response times their customers were demanding — something on the order of seconds (in other words, the need to scan millions of objects/second) — required a new type of query engine. This led them on a four-year journey to create Doradus, one of Dell Software Group’s first open-source projects.
Doradus is a server framework that runs on top of Cassandra. To build Doradus, the team borrowed from several well-accepted paradigms. They used traditional OLAP techniques to allow data to be arranged into static, multidimensional cubes. They leveraged the vertical orientation and efficient compression of columnar databases. And, from the NoSQL world, they employed sharding. The result: a storage and query engine called Doradus OLAP that stores data up to 1M objects/second/node, providing nearly real-time data warehousing. This architecture also allows for extreme compression of the data, sometimes producing up to a 99% reduction in space usage.
This extremely dense storage means that data that once took multiple nodes can now be stored on a single node, allowing for fast queries without the expense of a large cluster. Because Doradus is built on top of Cassandra, the option to scale out is still there. This allows for sharding and replication, and also takes advantage of Cassandra’s failover features. Read more…
