How Twitter Is Moving To the Cassandra Database 157

MyNoSQL has up an interview with Ryan King on how Twitter is transitioning to the Cassandra database. Here's some detailed background on Cassandra, which aims to "bring together Dynamo's fully distributed design and Bigtable's ColumnFamily-based data model." Before settling on Cassandra, the Twitter team looked into: "...HBase, Voldemort, MongoDB, MemcacheDB, Redis, Cassandra, HyperTable, and probably some others I'm forgetting. ... We're currently moving our largest (and most painful to maintain) table — the statuses table, which contains all tweets and retweets. ... Some side notes here about importing. We were originally trying to use the BinaryMemtable interface, but we actually found it to be too fast — it would saturate the backplane of our network. We've switched back to using the Thrift interface for bulk loading (and we still have to throttle it). The whole process takes about a week now. With infinite network bandwidth we could do it in about 7 hours on our current cluster." Relatedly, an anonymous reader notes that the upcoming NoSQL Live conference, which will take place in Boston March 11th, has announced their lineup of speakers and panelists including Ryan King and folks from LinkedIn, StumbleUpon, and Rackspace.

ScummVM 0.13.0 Delivers New Adventure Games 69

KingofGnG writes "The classics, by definition, never go out of fashion, let alone if they are the graphic adventures of past decades. The preferred tool of true adventurers is ScummVM, software that works as an interpreter between data files of such adventures and modern operating systems. 6 months after the release of version 0.12.0, developers have now delivered a new main release of the virtual machine, which includes novelties both for the interface and supported games."

Comment Fair comparison considering the scenario (Score 4, Interesting) 240

He is comparing the usability of the two very different applications for a quite limited scenario, namely setting up very simple web sites with only a few static pages. For larger projects Wordpress simply won't do the job, but in that simple case, I agree that WordPress is a often much better choice. For my personal homepage I tried out lots of Open Source CMS, but finally got stuck with WordPress + some plugins. It does a surprisingly good job as CMS, but I would not recommend it for - say - my company's website.

Doing the Math On the New MacBook 783

Technologizer writes "Apple's new MacBook is a significantly different machine than its predecessor — a slicker laptop at a higher price point. But does it carry a large price premium over similar Windows PCs? I did a painstaking spec-by-spec comparison versus three roughly comparably-configured Windows machines, and came to the conclusion that the value it offers for price paid is not out of whack with the Windows world." The article uses the phrase "Mac tax," which one commenter points out is a recent Microsoft marketing canard.

Getting Away With a Cheap Graphics Card 290

theraindog writes "High-end graphics cards get all the glory, but most folks have a difficult time justifying $300 or more for a single PC component. But what if you could get reasonable performance in all the latest games from a budget card costing as little as $70? With game developers targeting the relatively modest hardware available in current consoles and trickle-down bringing cutting-edge features down to budget price points, today's low-end graphics cards are more capable than ever. To find out which one offers the best value proposition, The Tech Report has rounded up eight graphics cards between $70 and $170, comparing their game performance, Blu-ray playback acceleration, noise levels, and power consumption, with interesting results."

Office 2007 Fails OOXML Test With 122,000 Errors 430

I Don't Believe in Imaginary Property writes "Groklaw is reporting that some people have decided to compare the OOXML schema to actual Microsoft Office 2007 documents. It won't surprise you to know that Office 2007 failed miserably. If you go by the strict OOXML schema, you get a 17 MiB file containing approximately 122,000 errors, and 'somewhat less' with the transitional OOXML schema. Most of the problems reportedly relate to the serialization/deserialization code. How many other fast-tracked ISO standards have no conforming implementations?"
