I came to the decision to write such an editor after getting completely sick of vi, both from a feature and user interface point of view. I needed an editor that I could use through a telnet connection or a phone line and that wouldn’t fire off a full-blown LITHP1 operating system just to do some editing. A concise overview of the main features follows: • three user interfaces: control keystrokes, command line, and menus; keystrokes and menus are completely configurable; • syntax highlighting; • full support for UTF-8 files, including multiple-column characters; • 64-bit -
CNTR: Lightweight OS Containers

Moreover, standard for deploying applications in data centers. containers significantly reduce operational costs through However, deployed containers frequently include a higher consolidation density and power minimization, wide-range of tools (e.g., debuggers) that are not required especially in multi-tenant environments. Because of all for applications in the common use-case, but they these advantages, it is no surprise that containers have seen are included for rare occasions such as in-production wide-spread adoption by industry, in many cases replacing debugging. As a consequence, containers are significantly altogether traditional virtualization solutions [17]. larger than necessary for the common case, thus increasing the build and deployment time. Despite being lightweight, deployed containers often include a wide-range of tools such as shells, editors, CNTR1 provides the performance benefits of lightweight coreutils, and package managers. These additional tools containers and the functionality of large containers by are usually not required for the application’s core function splitting the traditional container image into two parts: the — the common operational use-case — but they are “fat” image — containing the tools, and the “slim” image included for management, manual inspection, profiling, — containing the main application.

In practice, this significantly allows the user to efficiently deploy the “slim” image and increases container size and, in turn, translates into then expand it with additional tools, when and if necessary, slower container deployment and inefficient datacenter by dynamically attaching the “fat” image. -
UKUI: a Lightweight Desktop Environment Based on Pluggable
2016 International Conference on Artificial Intelligence and Computer Science (AICS 2016) ISBN: 978-1-60595-411-0 UKUI: A Lightweight Desktop Environment Based on Pluggable Framework for Linux Distribution Jie YU1, Lu SI1,*, Jun MA1, Lei LUO1, Xiao-dong LIU1, Ya-ting KUANG2, Huan PENG2, Rui LI1, Jin-zhu KONG2 and Qing-bo WU1 1College of Computer, National University of Defense Technology, Changsha, China 2Tianjin KYLIN Information Technology Co., Ltd, Tianjin, China *[email protected] *Corresponding author Keywords: Desktop environment, Ubuntu, User interface. Abstract. Ubuntu is an operating system with Linux kernel based on Debian and distributed as free and open-source software. It uses Unity as its default desktop environment, which results in more difficulties of usage for Microsoft Windows users. In this paper, we present a lightweight desktop environment named UKUI based on UbuntuKylin, the official Chinese version of Ubuntu, for Linux distribution. It is designed as a pluggable framework and provides better user experience during human-computer interaction. In order to evaluate the performance of UKUI, a set of testing bench suits were performed on a personal computer. Overall, the results showed that UKUI has better performance compared with Unity. Introduction Linux is a freely available operating system (OS) originated by Linux Torvalds and further developed by thousands of others. Typically, Linux is packaged in a form known as a Linux distribution for both desktop and server use. Some of the most popular mainstream Linux distributions are Red Hat [1], Ubuntu [2], Arch [3], openSUSY [4], Gentoo [5], etc. There are several desktop environments available for nowadays modern Linux distributions, such as XFCE [6], GNOME [7], KDE [8] and LXDE [9]. -

An Introduction to the X Window System Introduction to X's Anatomy
An Introduction to the X Window System Robert Lupton This is a limited and partisan introduction to ‘The X Window System’, which is widely but improperly known as X-windows, specifically to version 11 (‘X11’). The intention of the X-project has been to provide ‘tools not rules’, which allows their basic system to appear in a very large number of confusing guises. This document assumes that you are using the configuration that I set up at Peyton Hall † There are helpful manual entries under X and Xserver, as well as for individual utilities such as xterm. You may need to add /usr/princeton/X11/man to your MANPATH to read the X manpages. This is the first draft of this document, so I’d be very grateful for any comments or criticisms. Introduction to X’s Anatomy X consists of three parts: The server The part that knows about the hardware and how to draw lines and write characters. The Clients Such things as terminal emulators, dvi previewers, and clocks and The Window Manager A programme which handles negotiations between the different clients as they fight for screen space, colours, and sunlight. Another fundamental X-concept is that of resources, which is how X describes any- thing that a client might want to specify; common examples would be fonts, colours (both foreground and background), and position on the screen. Keys X can, and usually does, use a number of special keys. You are familiar with the way that <shift>a and <ctrl>a are different from a; in X this sensitivity extends to things like mouse buttons that you might not normally think of as case-sensitive. -
Pipe and Filter Architectural Style Group Number: 5 Group Members: Fan Zhao 20571694 Yu Gan 20563500 Yuxiao Yu 20594369
Pipe and Filter Architectural Style Group Number: 5 Group Members: Fan Zhao 20571694 Yu Gan 20563500 Yuxiao Yu 20594369 1. Have its own vocabulary for its components and connectors? (define) The Pipe and Filter is an architectural pattern for stream processing. It consists of one or more components called filters. These filters will transform or filter data and then pass it on via connectors called pipes. These filters, which merely consume and produce data, can be seen as functions like sorting and counting. All of these filters can work at the same time. Also, every pipe connected to a filter has its own role in the function of the filter. When data is sent from the producer (pump), it goes through the pipes and filters, and arrives the destination (sink). The pump can be a static text file or a keyboard input. The sink can be a file, a database or a computer screen. 2. Impose specific topological constraints? (diagram) Figure 1 shows a basic structure of Pipe and Filter architecture style. In this example, there are five filters and eight pipes. Each filter will get input from one or more pipes and pass it via pipes. The combination of several filters and pipes can be regarded as a “big” filter. Figure 2 is an specific example using Pipe and Filter architecture style. This example demonstrates a simple process of making sandwiches. To begin with, the first 4 filters can work simultaneously for preparation. Once they are done, the 5th filter can get the output and combine them together. Next, a following filter will add sauce to it and pass it to customer through a pipe. -

A shell script is a PC system intended to be controlled by the UNIX shell which is a charge line translator. The different tongues of shell scripts are thought to be scripting dialects. Regular operations performed by shell scripts incorporate document control, program execution, and printing content. A shell script can give an advantageous variety ofa framework order where unique environment settings, charge alternatives, or post-transforming apply naturally, yet in a manner that permits the new script to still go about as a completely typical UNIX summon. The real ideas like Programming in the Borne and C-shell, in which it would be clarified that how shell programming could be possible in Borne and C-shell. -
