The Kernel Hacker's Guide to Source Code Control
BitKeeper also allows you to see easily all of the changes that have happened to a specific file over time. You can see if the file was modified by one of the main kernel patches or by yourself. An example of the changes that have happened to the drivers/usb/serial/usbserial.c file over time in my repository can be seen in Figure 3. With this tool, you can see what other changes happened at the same time and even what line of code was modified in which version.
One of the strongest benefits of using BitKeeper for your kernel development is that it is a very powerful version control system, and it allows you to work with other developers on the same sections of code at the same time. You can allow other people to pull from your working tree, or you can set up a local server to store your working tree. See the BitKeeper tutorial and documentation for some good examples of how this can be set up and how the development life cycle can be used.
I have shown two different ways of doing Linux kernel development, one with only patch and diff and one using BitKeeper. Personally, BitKeeper has enabled me to spend more time actually doing development work and less time messing with merges. It has also kept me sane in trying to track the 2.2, 2.4 and 2.5 kernel trees for the Linux USB and Linux Hot Plug PCI drivers.

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
