Redirecting standard output on the PocketLinux operating system

Linux provides any tools you need as a developer to operate a scalable, secure servers. When Corporations are happy with the used software they donate money to the communities in order to be able to continue their work and developing new versions. Instead, it focuses on user-space system-level programming, that …

The importance of psacct on the Rasberry Pi

When you boot a system that uses the GRUB Legacy bootloader, you'll see a menu that shows the boot options that you defined in the configuration file. In a very real sense Linux is a product of the Internet or World Wide Web (WWW). Device drivers have to be careful …

Getting up and running with Gnome Flashback

Its purpose is to provide a financial incentive for producing such works in order to benefit society as a whole. How does the kernel know which directory to look in to find a given filename? Any microprocessor that wishes to support an operating system must have a programmable interval timer …

A technical overview of mtr

Software running on the CPU must be able to read and write those controlling registers. Each process is in turn associated with exactly one uid, which identifies the user running the process, and is called the process's real uid. For many people, the next step will be to carefully read …

Create your own video streaming server with VectorLinux

Getting involved with kernel development is, paradoxically, both easier than it seems like it should be, and also ridiculously difficult. These unique addresses are built into each ethernet device when they are manufactured and it is usually kept in an SROM2 on the ethernet card. Different distributions have chosen varying …

Interesting apps based on ranlib

Users of closed source operating systems must report the bug to the manufacturer and wait for the manufacturer to develop, test, and release a solution to the problem, known as a hot fix. A regular file contains bytes of data, organized into a linear array called a byte stream. As …

Focus on the outcome when using ram

Every program that is running is called a process. A process's resources, along with data and statistics related to the process, are stored inside the kernel in the process's process descriptor. I use Linux for everything. Accepting Linux need not mean using it or even liking it.

Running swapper inside …

Understanding the fundamentals of xfsdump

Its one-time installation is sufficient and every time a new version is released (very early every month), you get an updated machine. Background processes are those whose process group ID differs from the terminal's; such processes are immune to keyboard-generated signals. There will always be at least two kinds of …

How to evaluate error messages with objcopy

Even your car has Linux running under the hood. For small contributions and bug fixes, it is unlikely that there will be any long-term maintenance expected. For example, when we add a user named "paul," Linux creates a directory /home/paul. The first, the old timer mechanism, has a static …

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 …

Running Gnome on CentOS

A thread is the unit of activity within a process. This is also the reason serious Linux users prefer the command line. However, such programs are typically also made available for free (usually as a free download from the Internet). lsmod simply reformats /proc/modules which is built from the …

Does it run under KDE on the Linux Mint distro?

If the kernel handles the signals, it will do the default actions required for this signal. The first method is most often the easiest, as long as your system UEFI boot manager allows you to disable the secure boot feature. The kernel allocates a new module data structure and enough …

Understanding the library linker game

Becoming familiar with Linux can result in a substantial financial savings because the software (both the operating system and the application programs) is available for free and because Linux can run on older and cheaper computers. In 1978, Kernighan and Ritchie wrote, "The C Programming Language," a book that is …

Its all about rdate

As such it is possible to have two or more files and directories with the same name but letters of different case. I say somewhat, because the use of sed in conjunction with pipes is somewhat more comfortable (at least to this author) for substitution of text in files. Software …

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 …

Getting up and running with Lumina

The read/write heads are moved across the surface of the platters by an actuator. The Linux kernel, supporting both preemptive multitasking and virtual memory, provides every process both a virtualized processor and a virtualized view of memory. Other common sections in ELF executables are the absolute section (which contains …

Configuration via the terminal

Workspaces is a feature I would never trade for anything else. Not only you earn more capabilities as a developer, you also learn (sometimes the hard way) how to solve issues, monitor your machine for potential problems, configure different components and more. Putting morals before convenience and ease may be …

Editing with vi and esdcat

Copyleft advocates also point out that although code released under the GLP cannot be incorporated directly into proprietary software that does not make its full source code freely available, it is still possible to use it effectively with proprietary code. If the substring matches more than one job, bash reports …

Principles of git-series under Linux

First of all the DMA controller knows nothing of virtual memory, it only has access to the physical memory in the system. If they will then it removes the sem_queue data structure from the operations pending list and applies the semaphore operations to the semaphore array. Institutions that rely solely …
