Firefox to get massive JavaScript performance boost

Mozilla is leveraging an impressive new optimization technique to bring a big performance boost to the Firefox JavaScript engine. The code was merged today (but is not yet ready to be enabled by default in the nightly builds) and is planned for inclusion in Firefox 3.1, the next incremental update of the open-source web browser.

They are "getting ready to take JavaScript performance into the next tier" with a radically innovative optimization tactic called tracing that has already produced performance improvements ranging between 20 and 40 times faster in some cases. They believe that this is just the beginning of what can be accomplished with tracing, and they expect to be able to achieve even better speed as the work continues.

The Only Thing We Have To Fear Is Premature Standardization

The web is made of open standards. This was a significant factor in the web’s displacement of proprietary application platforms. Openness is hugely attractive, so much so that the web dominates over competitors with better technologies. The difficult tradeoff that comes with a standards-based approach is that it is difficult to innovate. As a result, the basic technologies of the browser have been stalled for a decade. What innovation we’ve enjoyed, such as the Ajax revolution, has come by mining all of the latent, accidental potential of the existing standards. That potential has been used up.

Court: violating copyleft = copyright infringement

A federal appeals court has overruled a lower court ruling that, if sustained, would have severely hampered the enforceability of free software licenses. The lower court had found that redistributing software in violation of the terms of a free software license could constitute a breach of contract, but was not copyright infringement. The difference matters because copyright law affords much stronger remedies against infringement than does contract law. If allowed to stand, the decision could have neutered popular copyleft licenses such as the GPL and Creative Commons licenses. The district court decision was overturned on Wednesday by the United States Court of Appeals for the Federal Circuit.
