Can you recommend a Web browser for the Raspberry Pi?

The entire Linux kernel was written from scratch, without employing any code from proprietary sources. Instead of a simple binary check, capabilities allow the kernel to base access on much more fine-grained settings. The most popular include Perl, Python, PHP, and Tcl. If you can use a computer or other …

Can you get Gnome to work on your own distro?

Linux moving into the mainstream is a great thing. Background processes that attempt to read from (write to) the terminal are sent a SIGTTIN (SIGTTOU) signal by the terminal driver, which, unless caught, suspends the process. Another excellent source for assistance (and encouragement) is a local Linux Users Group (LUG …

Understanding the fundamentals of CUPS

The smallest addressable unit on a block device is the sector. With the connection established both ends are free to send and receive data. When it is started up, usually at system boot time, it opens up an Inter-Process Communication (IPC) channel to the kernel. At kernel initialization time, the …

Starting the portmap/rpcbind daemon at boot time

Like interrupts, some devices have a fixed DMA channel. Most processes consist of only a single thread; they are called single-threaded. The data is read by a head, which can detect whether a particular minute particle is magnetized. On GNU/Linux systems a file command can be used to identify …
