A new Blog on Technology, Art and Culture curated by Benjamin Schweizer.
Over time web technologies have evolved to give web developers the ability to create new generations of useful and immersive web experiences. Today's web is a result of the ongoing efforts of an open web community that helps define these web technologies, like HTML5, CSS3 and WebGL and ensure that they're supported in all web browsers.
The Large Hackerspace Convention Episode II should be exactly that. Hackerspaces and hackerspace-folks from all over Germany, Europe, the world, our galaxy, and the rest of the universe will meet for an informal exchange of knowledge. Together we'll talk about our experiences and ideas regarding the hackerspace movement.
As part of implementing the many products and services offered by Google, we have built a collection of systems and tools that simplify the storing and processing of large-scale data sets, and the construction of heavily-used public services based on these data sets. These systems are intended to work well in Google's computational environment, which consists of large numbers of commodity machines connected by commodity networking hardware. Our systems handle issues like storage reliability and availability in the face of machine failures, and our processing tools make it relatively easy to write robust computations that run reliably and efficiently on thousands of machines. In this talk I'll highlight some of the systems we have built, and discuss some challenges and future directions for new systems.
Is your browser configuration rare or unique? If so, web sites may be able to track you, even if you limit or disable cookies.
I think it's not standards conform, but sometimes it is desireable to cache remote errors like 404 etc. Below is a runtime patch that wraps _entry_disposition() so that it uses the Cache-Control header also for errnous responses.
Dag is "disappointed about the lack of best practices and standardization regarding KVM on GFS clustering. ... » Have you been setting up libvirt environments, share your best practices here ! If you found interesting links to information, let us know too. Let's fill this void."
Using MongoDB to implement tree structures has some advantages, but as it lacks features that traditional RDBMSes have (like table locking and transactions), it is easy to create race conditions during simultanous operations. This is a pretty generic problem and I hope we can emphasize common problems and best practices on the implementation of thread-safe tree tables here.
The first time I saw details about the Tigon2, I came up with the idea that it could be used to make a back door, remote gdb stub or remote sniffer in the firmware. In this paper, I will explain a way to develop such firmware programs and also the associated security risks.
