Desktop: Your Desktop over ssh running inside of a Docker container Motivation I’ve worked for the last 4 years in the financial market and I’m a heavy Excel user. I also use the browser a lot and since I started my summer job as financial intern at dotCloud I’ve been playing with docker. So, why don’t we take advantage of the cloud and use these and other heavy applications (in terms of processing and memory usage) within a container (lighter than a normal VM). Let’s get started! Arch User Repository The Arch User Repository (AUR) is a community-driven repository for Arch users. It contains package descriptions (PKGBUILDs) that allow you to compile a package from source with makepkg and then install it via pacman. The AUR was created to organize and share new packages from the community and to help expedite popular packages' inclusion into the community repository.

How does disk defrag work The word "disk defrag" is typically used to refer to the Microsoft Windows utility called Disk Defragmenter. It is designed to solve a problem that occurs because of the way hard disks store data. If you have read the article How Hard Disks Work, then you know three key facts about hard disks: Hard disks store data in chunks called sectors. If you imagine the surface of the disk divided into rings (like the rings of a tree), and then imagine dividing each ring into pie-slices, a sector is one pie-slice on one ring. Each sector holds a fixed amount of data, like 512 bytes.The hard disk has a small arm that can move from ring to ring on the surface of the disk.
20 Linux Server Hardening Security Tips Securing your Linux server is important to protect your data, intellectual property, and time, from the hands of crackers (hackers). The system administrator is responsible for security Linux box. In this first part of a Linux server security series, I will provide 20 hardening tips for default installation of Linux system. Linux Server Hardening Checklist and Tips The following instructions assume that you are using CentOS/RHEL or Ubuntu/Debian based Linux distribution.
file - Docker Documentation Docker can build images automatically by reading the instructions from a Dockerfile. A Dockerfile is a text document that contains all the commands you would normally execute manually in order to build a Docker image. By calling docker build from your terminal, you can have Docker build your image step by step, executing the instructions successively. This page discusses the specifics of all the instructions you can use in your Dockerfile. To further help you write a clear, readable, maintainable Dockerfile, we've also written a Dockerfile Best Practices guide. Usage
Docky in ArchLinux does not launch anymore after a system upgrade If you, like me, use docky for managing your windows and launching your applications, you should have noted that recently an ArchLinux update broke docky because it installed a newer version of mono that docky doesn’t like. Anyways, here is how to fix it. This is the error when trying to launch docky: Introduction To DNS (Domain Name System) DNS, Domain Name System, is a hierarchical distributed naming system for computers, servers and every resource connected via internet.

Linux Mint vs. Ubuntu: the Best Option? For the last few years, there has been something of a popularity contest between two well-known Linux distros: Linux Mint and Ubuntu. Both of these distributions share the same code base, as Ubuntu is based on Debian and Linux Mint is based on Ubuntu. In both instances, the distributions took the foundation that Debian built, then added their own flavor to make it more user friendly. The similarities between the two distributions go even further, in that Ubuntu packages work flawlessly on Linux Mint, just as Ubuntu PPAs work well on Linux Mint. Managing Application Code in Linux Containers Many developers have heard of Linux containers and Docker. But how do you deploy your code to an application running in Linux containers? Let’s go over that in this article, using a very simple yet effective workflow. We’ll focus on WordPress, but these principles can be used with Ruby, Python, or even Go applications. I think most of the time, users need to manage WordPress for adding/updating plugins, themes etc. Although, the same can be achieved via the WordPress UI, we will use it as a simple use case to demonstrate propogating code changes to the WordPress application.
Install Yaourt on Arch Linux Yet AnOther User Repository Tool is a package helper similar to packer that allows user to easily install packages from Arch User Repository. Yaourt is not in the official repository so it needs to be installed manually like any other AUR package without a package helper. Create a temporary installation directory. Facebook to allow ad targeting by email, user ID and phone number Facebook to allow ad targeting by email, user ID and phone number Facebook appears to be preparing an option for advertisers to target users by email address, user ID or phone number, based on an option that was temporarily visible in the Power Editor tool. Sources familiar with Facebook’s ad plans previously told us that the company was working with some premium advertisers to target audiences by email address, though we had not heard about the UID and phone number options. These are powerful new opportunities for businesses to reach their existing customers and leads, who may be increasingly difficult to reach through traditional email and telemarketing campaigns. If this test rolls out to all Power Editor users and the Ads API, companies will be able to remarket to people through News Feed and other Facebook ad units. Some Power Editor users temporarily had access to a new “Custom Audiences” tab today.
Valve: Linux More Viable Than Windows 8 for Gaming In a presentation at Ubuntu Developer Summit currently going on in Denmark, Drew Bliss from Valve said that Linux is becoming more viable platform as an alternative to Windows 8. Windows 8 ships with its own app store and it is moving away from an open platform model. Some other points from the talk: Steam client is running nicely on Ubuntu and many developers have approached them with good game products.Cooperation with Canonical has been good.Ubuntu is preferred platform as it has a large user base and good community support with a strong company like Canonical behind it. Linux has everything they need: good OpenGL, pulseaudio, OpenAL and input support.New Source engine games will be available for Linux.No firm time frame for Steam Linux release, but soon.Copy protection is up to the game publishers.
