Boost productivity when working with code, using the syntax highlighting programming features automatic code completion and other features Eclipse. Eclipse is an excellent IDE (Integrated Development Environment - IDE), open source software, which has many useful features. Eclipse runs on any UNIX ®-platform, such as Linux ®, Solaris, AIX ® and HP-UX, with the Java ™ Runtime Environment (JRE) version 1.4 or higher, and a library of SWT. In Eclipse, easy enough to create a new project or import an existing Eclipse-project, but how to implement this in the IDE is written by a third-party code? And what if you need to compile the project without modifying its existing makefile or configure script - the most common ways of building software in UNIX? This article provides answers to these questions.

Virtual / proc filesystem offers a new approach to the interaction of the Linux ® kernel and user space. In this virtual file system contains files by reading and writing that you can manipulate the structure of the kernel. In contrast to ordinary files, their contents are dynamically generated by the kernel. This article tells you about the virtual / proc file system and shows it in action

Initially, the / proc filesystem was designed as a means of providing information about processes running on the system. But because of its convenience, many kernel subsystems have to use the file system as a means of providing information and dynamic configuration.

The / proc filesystem contains a directory (for structuring information) and virtual files. Virtual file, as has been said, can provide the user with information obtained from the nucleus and, furthermore, serve as a means of communicating the core user information. In fact, the virtual file is not necessarily performs both functions, but in this article I will talk about how to configure the file system for both input and output.

Install mpd.

MPD - a demon player - which can be run with the system and to infer media stream to different resources. Open the console (in my case - terminal poklyuchaemsya by ssh)

$ Sudo apt-get install mpd

After installation, - the right config for mpd. I will describe what to write - consistently.
Setting up mpd

$ Sudo nano / etc / motd.conf

Install grub2-splashimages

First install the package grub2-splashimages. Make sure you have exactly Grub2 rather than GRUB 0.97 before you start to do something! Note that in ubuntu 9.10 GRUB2 set only when finishing the installation, when upgrading from 9.04 GRUB is 0.97.

$ Sudo apt-get install grub2-splashimages

To set an image loader

After installation, you can find some images in the directory: / usr / share / images / grub / default GRUB works with 640 ? 480. Of course, that most modern video cards support to higher resolutions. You can find the highest resolution available that you entered on the command line Grub (press 'c' in the boot menu) and type

vbeinfo

Suppose you have to define the resolution 1024 ? 768 resolution and color depth 32-bit. Now, given permission, you can resize your chosen image and save it as TarGA (tga) image (Gimp to deal with it on cheers) to the directory / usr / share / images / grub /.

The PostgreSQL Global Development Group announces the beta release of PostgreSQL 9.2, which will include major increases in performance and both vertical and horizontal scalability. The PostgreSQL Project asks all users to download and begin testing 9.2 Beta as soon as possible.

Major performance and scalability advances in this version include:

• Index-only scans, allowing users to avoid inefficient scans of base tables
• Enhanced read-only workload scaling to 64 cores and over 300,000 queries per second
• Improvements to data write speeds, including group commit
• Reductions in CPU power consumption
• Cascading replication, supporting geographically distributed standby databases

Install and run

Ubuntu Enterprise Cloud product based on Eucalyptus, which allows you to run your personal Amazon-EC2-like cloud. It is much easier than you think. The latest beta release of Ubuntu Server 9.10, you can easily create a cloud computing infrastructure using the installer from the CD.

Requirements

To deploy a minimal infrastructure clouds, you'll need at least two dedicated systems. One of them will support the controller clouds (cloud controller - clc), the cluster controller (cluster controller - cc), walrus (S3-like service for data storage) and the data controller (storage controller - sc). For him the need to drive fast and powerful enough and fast processor. Other systems are controllers nodes (node ??controllers - nc) with the current state. For them to use processors with an extension VT, multinucleated, large amounts of RAM and fast disks. In both cases strongly suggest supporting 64-bit.
Installation of the cloud / cluster controller

While Linux is running our phones, friend requests, tweets, financial trades, ATMs and more, most of us don't know how it's actually built. This short video takes you inside the process by which the largest collaborative development project in the history of computing is organized. Based on the annual report "Who Writes Linux," this is a powerful and inspiring story of how Linux has become a community-driven phenomenon. More information about Linux and The Linux Foundation can be found at http://www.linuxfoundation.org/ and http://www.linux.com/

20 years have passed, and Linux is stronger than ever...

Linux Foundation celebrating 20 years of Linux

Today marks two years to the day since the first version of Dancer, micro web application framework for Perl hit CPAN!

Dancer has come a long way since then, thanks to the awesome community and user base built up around the project since then.

In these two years, Dancer had countless valuable contributions from a large list of contributing users, gathered over 300 watchers on GitHub, had 84 people fork the repository on GitHub, had 620 pull requests submitted... amazing stuff.

You are busy churning out code or managing the developers. You care about Perl but don't have time to go through tens and hundreds of articles and blog posts every day. You want to keep an eye on the development of perl without drowning in a sea of blog posts. You need someone to point out the most important news and articles in the Perl World.

Let me try to be your guide.
