Google Web Toolkit out of beta as of 1.4 release

Wednesday, August 29, 2007

By Dan Peterson, Google Web Toolkit teamGoogle Web Toolkit (GWT)Google Web Toolkit (GWT) version 1.4make GWT bettercheck out the storyspecifics about GWT 1.4
There's lots and lots of cool new stuff in GWT 1.4, so it's hard to know where to start. How about application performance?! This release includes several breakthroughs that make your compiled GWT code significantly smaller and faster. Many users are reporting that after a simple recompile with 1.4, their applications are up to 30% smaller and 20%-50% faster. And startup time in particular is now highly optimized thanks to a new bootstrapping technique and the availability of image bundles. To see the new hotness in action, try visiting the new-and-improved Mail sample a few times. It's darn fast the very first time you visit it, but subsequent visits are insanely fast. That's because, in addition to a fast initial startup, GWT code uses a clever caching technique to prevent applications from making unnecessary HTTP requests. As Joel Webber (Tech Lead of GWT Core Libraries) would say, "The fastest HTTP requests are those that do not, in fact, occur."

Optimisation data for HTML5 parser implementors

Tuesday, August 7, 2007

By Ian Hickson, editor of the HTML5 specificationLast month, just before I left on vacation, I posted three sets of data to help implementors of the HTML5 parser specification optimise their code. There are several implementations coming along, for example those that are part of the html5lib project and the one behind Validator.nu.The three sets of data that I posted are all derived from parsing several billion documents from Google's Web search index using a parser I wrote in Sawzall.The first set of data gives the relative aggregate distribution of invocations of the "in head", "in body", and "in table" insertion modes, for each of the insertion modes. This allows implementors to determine, for instance, that invoking the "in body" code while in a cell must be very efficient, while invoking the "in body" code from the "after frameset" code need not be as efficient, in case the implementor has a strategy that optimises one at the cost of another. See: documentation, data.The second set of data gives the relative aggregate distribution of tokens for each phase/insertion mode pair. This can help implementors that are using a cascade of if statements decide on the right order for their statements. For instance, the most common token type seen in the "in body" insertion mode is character data, and the second most token is the start tag token for an a element, but the isindex start tag was almost never seen. This tells implementors that they should check for characters and a start tags long before checking for isindex tags. See: documentation, data.The last set of data examines the number of attributes per element. It allows implementors to decide on the optimum memory allocation strategy for attributes. For example, since most elements have 9 or fewer attributes, the data structure that stores attributes can be optimised for simply having 9 attributes, using little memory, and if an element has more than this number of attributes, the implementation can switch to a separate implementation that is more memory-heaving but is optimised for large numbers of attributes. See: data.I hope this data is useful!

Hibernate Shards

What sharding is and what it means in the world of Hibernate

How the word "shards" is common at Google (the equivalent of "smurf" in The Smurfs)

Why you would want to shard your data to give you increased scalable performance

How the Hibernate Shards project doesn't mess with the core APIs, allowing you to add sharding unobtrusively

What you need to think about if you want to shard your data, and how you can design a schema that has a dimension that is easily sharded. This includes designing without complex relationships.

How you could create a crazy project that shards data across multiple databases (as in, one mysql, one Oracle), but that would be crazy

The various strategies to define how you retrieve your objects across the distributed data store

How this compares with horizontal partitioning at the database level itself (e.g. new features in MySQL, PostgreSQL, and others)

And much, much more.
