Gene and guest host Jeremiah Lott discuss various profiling tools to get the most efficiency out of your hardware. In this episode they focus on using profiling tools to optimize the kernel.

Maciej and guest host Scott Gilbertson discuss their experience at the Embedded World Conference in Nurnberg, Germany.

For this topic, Maciej invited Timesys engineers, Justin and Scott, to participate. Both engineers, having enjoyed using Nokia's software on the Neo phone and having experience with Qt/Embedded for Linux at Timesys, share their insight into the recently released graphics toolkit. The trio spends time introducing historical perspective on Qt and unsuccessfully tries to figure out the long list of names the package has had over the years. Scott talks about other open source graphics frameworks, such as GTK+ and Glade, and Justin introduces concepts around QtCreator.

For this episode, Maciej invited two Timesys engineers, Daniel and Jason (both of whom have been working with the Timesys desktop build system and a number of open source ones, including buildroot and LTIB), to participate. After introducing Timesys' approach to building complete Linux platform, the trio talks about the differences and similarities between buildroot, open embedded and LTIB, and also touch on mainstream distributions like Fedora and Ubuntu. Lastly, Daniel addresses a question received from a listener regarding tradeoffs in latency vs. throughput when migrating from a micro-kernel solution to Linux.

In this episode Maciej and Daniel, one of Timesys Linux gurus, talk about what's new in the 2.6.28 Linux kernel. The conversation focuses on several aspects of the 2.6.28 kernel that are particularly relevant to an embedded Linux engineer. The pair seems to enjoy in particular talking about the concept of the staging driver area in the kernel and the newly introduced Boot Tracer.

In this episode, our hosts talk about what's new in the 2.6.27 Linux kernel. Various new features are covered in detail, including support for UBIFS. The hosts discuss the benefits of UBIFS for developers and how UBIFS compares to JFFS2. Other topics touched on in this episode include valuable tidbits about embedded Linux features.
