If you believe something on this site has infringed your intellectual property rights, please contact us. What's Sublime Text Sublime Text is a cross-platform text and source code editor, with a Python application programming interface (API). Sublime Text is proprietary software. Its functionality is extendable with plugins. Most of the extending packages have free-software licenses and are community-built and maintained. Sublime Text lacks graphical setting dialogues and is entirely configured by editing text files. How to Get Sublime Text You can get the Sublime Text from http://www.sublimetext.com/.I recommend you to download Sublime Text 2, because Sublime Text…
Introduction Nginx is one of the most popular web servers in the world and is responsible for hosting some of the largest and highest-traffic sites on the internet. Tengine is a branch of Nginx which is created by Alibaba Inc. MariaDB is a database server developed by some of the original authors of MySQL and offers drop-in replacement functionality. Prerequisites Before you begin this guide, you should have a regular, non-root user with sudo privileges configured on your server. We will build all components from the source code. Of course, it's OK for you to install them using the apt-get command. All steps have been tested on Ubuntu 14.04. Install Tengine Install Required Packages Download and Compile the Source Code…
Clover is a new and exciting open source EFI bootloader. Developed over the past 3 years by a group of developers at Project OS X led by Slice, Clover aims to solve problems inherent in existing OS X installation methods and legacy bootloaders: Boots troublesome desktop and laptop BIOS/UEFI Uses native OS X installation media Ability to patch DSDT/kernel/kexts at boot time Creates OS X Recovery partition No boot0 error with 4K Advanced Format drives Solves multi-boot issues with Linux and Windows 7/8 Solves traditional bootloader NVRAM issues related to iMessage/FaceTime Clover has a completely different system of configuration with a decidedly steep learning curve. It can be confusing for those who have only ever used the more traditional Chameleon or…
Consistent hashing is a special kind of hashing such that when a hash table is resized and consistent hashing is used, only K/n keys need to be remapped on average, where K is the number of keys, and n is the number of slots. In contrast, in most traditional hash tables, a change in the number of array slots causes nearly all keys to be remapped. Consistent hashing achieves the same goals as Rendezvous hashing (also called HRW Hashing). The two techniques use different algorithms and were devised independently and contemporaneously. Problem with Distributed Cache The need for consistent hashing arose from limitations experienced while running collections of caching machines - web caches, for example. If you have a collection…
Design patterns represent the best practices used by experienced object-oriented software developers. Design patterns are solutions to general problems that software developers faced during software development. These solutions were obtained by trial and error by numerous software developers over quite a substantial period of time. This tutorial will take you through step by step approach and examples using Java while learning Design Pattern concepts. Three Types of Design Patterns Design patterns are divided into three fundamental groups: Behavioral Patterns, Creational Patterns, and Structural Patterns. Behavioral Patterns: Abstract Factory, Builder, Factory Method, Prototype, and Singleton. Creational Patterns: Adapter, Bridge, Composite, Decorator, Facade, Flyweight, and Proxy Structural Patterns: Chain of Resp., Command, Interpreter, Iterator, Mediator, Memento, Observer, State, Strategy, Template, and Visitor Seven Principles of Design Patterns Open Close Principle Software entities like…
Process What's Process? In computing, a process is an instance of a computer program that is being executed. It contains the program code and its current activity. Depending on the operating system (OS), a process may be made up of multiple threads of execution that execute instructions concurrently. Process states An operating system kernel that allows multi-tasking needs processes to have certain states. Names for these states are not standardized, but they have similar functionality. Orphan Process and Zombie Process Orphan process An orphan process is a computer process whose parent process has finished or terminated, though it remains running itself. In a Unix-like operating system, any orphaned process will be immediately adopted by the special init system process. This operation…
