Benchmarking Gentoo and Ubuntu..."As previously discussed on Linux Magazine, Gentoo is a source based distribution which lets the end user decide what their system will be. "All binary distributions make these choices for you, but building from source, Gentoo users can decide for themselves. They are able to choose what CPU their binaries will be built for, as well as GCC optimizations." [Read More at Linux Magazine]... [more]

How to plug the recent gcc compiler hole in Linux..."Everything has security problems, even Linux. An old and obscure problem with the gcc compiler was recently discovered to have left a security hole in essentially every version of Linux that anyone is likely to be running. Here's what you need to know about fixing it.

A new open-source compiler is now available..."IBM today announced the public availability of Milepost GCC, the world's first open source machine learning compiler. The compiler intelligently optimizes applications, translating directly into shorter software development times and bigger performance gains.

As the world economy began tanking last fall, a small group of open source developers decided to get together to try to build a better mousetrap--in this case by using a more efficient compiler.Their idea was simple--if you create code that is compiled more efficiently, then the programs can execute and run faster, saving energy, conserving computing resources and giving more bang for the buck for cash-strapped businesses that rely on open source applications in their IT infrastructures....

It applies to a given file (the 'Runtime Library') that bears a notice placed by the copyright holder of the file stating that the file is governed by GPLv3 along with this Exception.

There are many applications where efficient handling of bitsets determines the overall responsiveness of the user experience. For example, programs providing an index and search interface are likely to rely on bitsets at one stage or another to resolve user queries. In this two-part series we'll take a look at a few ways to handle bitsets and the performance trade-off of some of them.

A look at the impact of the GPL..."What was Richard Stallman's greatest achievement? Some might say it's Emacs, one of the most powerful and adaptable pieces of software ever written. Others might plump for gcc, an indispensable tool used by probably millions of hackers to write yet more free software. And then there is the entire GNU project, astonishing in its ambition to create a Unix-like operating system from scratch. But for me, his single most important hack was the creation of th... [more]
