FOSDEM
Free and Open source Software Developers' European Meeting (FOSDEM) is an annual software engineering conference. It is non-commercial and volunteer-organized with a focus on free and open-source software. Initiated in 2000, it is usually held during the first weekend of February, at the of the Université Libre de Bruxelles (ULB) in the southeast of Brussels, Brussels, Belgium. History FOSDEM was started in 2000 under the name Open Source Developers of Europe Meeting (OSDEM) by Raphael Bauduin. Bauduin said that since he felt he lacked the brains to properly contribute to the open-source community, he wanted to contribute by launching a European event in Brussels. Bauduin teamed up with Damien Sandras. The team repeated the event. The F (of FOSDEM) was added at the request of Richard Stallman. The Free Software Foundation's ceremony for the Award for the Advancement of Free Software was held at FOSDEM from 2002 to 2006 (for the awards for 2001 to 2005). The event has be ...

Klibc
In computing, klibc is a minimalistic subset of the standard C library developed by H. Peter Anvin. It was developed mainly to be used during the Linux startup process, and it is part of the early user space, i.e. components used during kernel startup, but which do not run in kernel mode.https://www.kernel.org/doc/Documentation/early-userspace/README These components do not have access to the standard library (usually glibc or musl) used by normal userspace programs. The development of klibc library was part of the 2002 effort to move some Linux initialization code out of the kernel. According to its documentation, the klibc library is optimized for correctness and small size. Because of its design, klibc is also technically suitable for embedded software in general on a variety of platforms, and is used even by full-featured programs such as the MirBSD Korn Shell. During the Linux startup process, klibc is loaded from within a temporary RAM file system, initramfs. It is inco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X32 ABI
The x32 ABI is an application binary interface (ABI) and one of the interfaces of the Linux kernel. The x32 ABI provides 32-bit integers, long and pointers ( ILP32) on Intel and AMD 64-bit hardware. The ABI allows programs to take advantage of the benefits of x86-64 instruction set (larger number of CPU registers, better floating-point performance, faster position-independent code, shared libraries, function parameters passed via registers, faster syscall instruction) while using 32-bit pointers and thus avoiding the overhead of 64-bit pointers. Details Though the x32 ABI limits the program to a virtual address space of 4 GiB, it also decreases the memory footprint of the program by making pointers smaller. This can allow it to run faster by fitting more code ''and'' more data into cache. The best results during testing were with the 181.mcf SPEC CPU 2000 benchmark, in which the x32 ABI version was 40% faster than the x86-64 version. On average, x32 is 5–8% faster on the SPEC C ...

RAID 6
In computer storage, the standard RAID levels comprise a basic set of RAID ("redundant array of independent disks" or "redundant array of inexpensive disks") configurations that employ the techniques of striping, mirroring, or parity to create large reliable data stores from multiple general-purpose computer hard disk drives (HDDs). The most common types are RAID 0 (striping), RAID 1 (mirroring) and its variants, RAID 5 (distributed parity), and RAID 6 (dual parity). Multiple RAID levels can also be combined or '' nested'', for instance RAID 10 (striping of mirrors) or RAID 01 (mirroring stripe sets). RAID levels and their associated data formats are standardized by the Storage Networking Industry Association (SNIA) in the Common RAID Disk Drive Format (DDF) standard. The numerical values only serve as identifiers and do not signify performance, reliability, generation, hierarchy, or any other metric. While most RAID levels can provide good protection ...

Automounter
An automounter is any program or software facility which automatically mount (computing), mounts filesystems in response to access operations by user programs. An automounter system utility (Daemon (computer software), daemon under Unix), when notified of file and directory access attempts under selectively monitored subdirectory trees, dynamically and transparently makes local or remote devices accessible. The automounter has the purpose of conserving local system resources and of reducing the coupling between systems which share filesystems with a number of servers. For example, a large to mid-sized organization might have hundreds of file servers and thousands of workstations or other Node (networking), nodes accessing files from any number of those servers at any time. Usually, only a relatively small number of remote filesystems (''exports'') will be active on any given node at any given time. Deferring the mounting of such a filesystem until a process actually needs to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CPUID
In the x86 architecture, the CPUID instruction (identified by a CPUID opcode) is a processor supplementary instruction (its name derived from " CPU Identification") allowing software to discover details of the processor. It was introduced by Intel in 1993 with the launch of the Pentium and SL-enhanced 486 processors. A program can use the CPUID to determine processor type and whether features such as MMX/ SSE are implemented. History Prior to the general availability of the CPUID instruction, programmers would write esoteric machine code which exploited minor differences in CPU behavior in order to determine the processor make and model. With the introduction of the 80386 processor, EDX on reset indicated the revision but this was only readable after reset and there was no standard way for applications to read the value. Outside the x86 family, developers are mostly still required to use esoteric processes (involving instruction timing or CPU fault triggers) to determine th ...

Pseudo Terminal
In some operating systems, including Unix-like systems, a pseudoterminal, pseudotty, or PTY is a pair of pseudo-device endpoints (files) which establish an asynchronous, Duplex (telecommunications), bidirectional communication (IPC socket, IPC) channel (with two ports) between two or more processes. One pseudo-device in the pair, the ''master'', provides means by which a terminal emulator or remote login server (e.g. a Telnet, Berkeley r-commands, rlogin, or Secure Shell server) computer process, process controls the slave. The other pseudo-device, the ''slave'', emulates a hardware serial port device, and is used by terminal-oriented programs such as shells (e.g. Bash (Unix shell), bash) as a processes to read/write data back from/to ''master'' endpoint. PTYs are similar to bidirectional pipes. Devpts is a Linux kernel virtual file system containing pseudoterminal devices. Linux implementation is based on UNIX System V, System V-style terminals (commonly referred as UNIX 98 pse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RPath
In computer science, rpath designates the run-time search path hard-coded in an executable file or library. Dynamic linking loaders use the rpath to find required libraries. Specifically, it encodes a path to shared libraries into the header of an executable (or another shared library). This RPATH header value (so named in the Executable and Linkable Format header standards) may either override or supplement the system default dynamic linking search paths. The rpath of an executable or shared library is an optional entry in the .dynamic section of the ELF executable or shared libraries, with the type DT_RPATH, called the DT_RPATH attribute. It can be stored there at link time by the linker. Tools such as chrpath and patchelf can create or modify the entry later. Use of the DT_RPATH entry by the dynamic linker The different dynamic linkers for ELF implement the use of the DT_RPATH attribute in different ways. GNU ld.so The dynamic linker of the GNU C Library searches f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmeta
Transmeta Corporation was an American fabless semiconductor company based in Santa Clara, California. It developed low power x86 compatible microprocessors based on a VLIW core and a software layer called Code Morphing Software. Code Morphing Software (CMS) consisted of an interpreter, a runtime system and a dynamic binary translator. x86 instructions were first interpreted one instruction at a time and profiled, then depending upon the frequency of execution of a code block, CMS would progressively generate more optimized translations. The VLIW core implemented features specifically designed to accelerate CMS and translations. Among the features were support for general speculation, detection of memory aliasing and detection of self modifying x86 code. The combination of CMS and the VLIW core allowed for the achievement of full x86 compatibility while maintaining performance and reducing power consumption. Transmeta was founded in 1995 by Bob Cmelik, Dave Ditzel, Colin Hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Netwide Assembler
The Netwide Assembler (NASM) is an assembler and disassembler for the Intel x86 architecture. It can be used to write 16-bit, 32-bit (IA-32) and 64-bit In computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, a ... (x86-64) programs. It is considered one of the most popular assemblers for Linux and X86, x86 chips. It was originally written by Simon Tatham with assistance from Julian Hall. , it is maintained by a small team led by H. Peter Anvin. It is open-source software released under the terms of a simplified (2-clause) BSD licenses, BSD license. Features NASM can output several binary formats, including COFF, OMF, a.out (file format), a.out, Executable and Linkable Format (ELF), Mach-O and binary file (.bin, binary disk image, used to compile operating systems), though position-indep ...
