Sun Microsystems is contributing Project Looking Glass, based on Java™ technology, to the open source community.

Project Looking Glass is an exploratory project to bring innovative 3D features to the desktop environment. The desktop interface will offer an intuitive, new 3D environment to interact with desktop applications featuring window transparency, rotation, zoom, multiple desktop workspaces, and miniaturization. Project Looking Glass offers a platform to realize a far richer and more entertaining user experience for existing and new applications in 2D or 3D. The technology enables developers to build highly visual 3D desktops and applications that will run on Linux systems such as Sun’s Java Desktop System. The Solaris™ environment will be supported in the near future.

If your vim have auto indent enabled, you may facing this problem. Vim are too smart to help you indent copied source code, and the comment line will kill your pasting very much. I usually do copy and paste source code from ebook or web page to a file so that I can compile and run for test. In this case vim is not helping. I use cat instead.

Let me tell you, I’m a busy man. I’m always on the go and my trusty laptop is the only thing to keep me company much of the time. Despite being here, there and everywhere I still need access to my files and folders at home. But how can I access my files, securely, from anywhere on the planet? It is simple with SSH.

If you’re not familiar with SSH you’ll definitely want to check it out. SSH stands for Secure SHell and is probably one of the most used programs on the internet with its long list of uses. It is always encrypted, always secure and easy to use. I have long used it on a daily basis and here is how you can do the same.

The zip program is a useful tool for archiving or transferring a set of files. A simple command like "zip archive dir" can quickly package a whole directory into a single compressed archive file (often called "zip file"). Depending on the type of files being packaged, the size of the archive often gets compressed to a fraction of the size of the original files.

Archiving With The zip And unzip Commands

While not perfect, support for scanners on Linux is constantly improving; just check the list of devices supported by SANE (Scanner Access Now Easy -- the scanning suite for Linux and other Unix-like systems). One thing that's still missing though is a way to make a scanner's buttons work on Linux. That's what this tutorial is about.

I run Ubuntu 6.10 (Egdy Eft) on my desktop system, but all required programs are available on most Linux distributions and, possibly, BSD variants. The actual programs you will need for this setup are:

I'm sure everyone reading here has used "-exec" with "find"; for example:

find . -name core -exec rm {} \;

When I want to do something more complex to each found file, I usually pass the name to another script:

find . -exec my shellscript {} \;

The most interesting and dangerous phase of this learning experience is when the start mucking about in the Command Line Interface (CLI). It’s exciting for them to suddenly feel powerful on their own computer. They can make sweeping changes with the tap of a few keys.

Sadly, they do this. A lot.

Before they really know what they’re doing. So I’ve implemented a few quick changes to their machines to always prompt before removing, copying or moving files.

I have switched to Xubuntu a few months ago coming from Kubuntu. In Kubuntu I liked the (already available) option of setting up a list of image files and have them randomly displayed as background image on the desktop. This was one of the things I have missed so far in Xfce. This small howto shows you how you can randomly display background wallpapers in XFCE.

  • Open Source NFV Part Four: Open Source MANO
    Defined in ETSI ISG NFV architecture, MANO (Management and Network Orchestration) is a layer — a combination of multiple functional entities — that manages and orchestrates the cloud infrastructure, resources and services. It is comprised of, mainly, three different entities — NFV Orchestrator, VNF Manager and Virtual Infrastructure Manager (VIM). The figure below highlights the MANO part of the ETSI NFV architecture.
  • After the hype: Where containers make sense for IT organizations
    Container software and its related technologies are on fire, winning the hearts and minds of thousands of developers and catching the attention of hundreds of enterprises, as evidenced by the huge number of attendees at this week’s DockerCon 2016 event. The big tech companies are going all in. Google, IBM, Microsoft and many others were out in full force at DockerCon, scrambling to demonstrate how they’re investing in and supporting containers. Recent surveys indicate that container adoption is surging, with legions of users reporting they’re ready to take the next step and move from testing to production. Such is the popularity of containers that SiliconANGLE founder and theCUBE host John Furrier was prompted to proclaim that, thanks to containers, “DevOps is now mainstream.” That will change the game for those who invest in containers while causing “a world of hurt” for those who have yet to adapt, Furrier said.
  • Is Apstra SDN? Same idea, different angle
    The company’s product, called Apstra Operating System (AOS), takes policies based on the enterprise’s intent and automatically translates them into settings on network devices from multiple vendors. When the IT department wants to add a new component to the data center, AOS is designed to figure out what needed changes would flow from that addition and carry them out. The distributed OS is vendor-agnostic. It will work with devices from Cisco Systems, Hewlett Packard Enterprise, Juniper Networks, Cumulus Networks, the Open Compute Project and others.
  • MapR Launches New Partner Program for Open Source Data Analytics
    Converged data vendor MapR has launched a new global partner program for resellers and distributors to leverage the company's integrated data storage, processing and analytics platform.
  • A Seamless Monitoring System for Apache Mesos Clusters
  • All Marathons Need a Runner. Introducing Pheidippides
    Activision Publishing, a computer games publisher, uses a Mesos-based platform to manage vast quantities of data collected from players to automate much of the gameplay behavior. To address a critical configuration management problem, James Humphrey and John Dennison built a rather elegant solution that puts all configurations in a single place, and named it Pheidippides.
  • New Tools and Techniques for Managing and Monitoring Mesos
    The platform includes a large number of tools including Logstash, Elasticsearch, InfluxDB, and Kibana.
  • BlueData Can Run Hadoop on AWS, Leave Data on Premises
    We've been watching the Big Data space pick up momentum this year, and Big Data as a Service is one of the most interesting new branches of this trend to follow. In a new development in this space, BlueData, provider of a leading Big-Data-as-a-Service software platform, has announced that the enterprise edition of its BlueData EPIC software will run on Amazon Web Services (AWS) and other public clouds. Essentially, users can now run their cloud and computing applications and services in an Amazon Web Services (AWS) instance while keeping data on-premises, which is required for some companies in the European Union.

Industrial SBC builds on Raspberry Pi Compute Module

On Kickstarter, a “MyPi” industrial SBC using the RPi Compute Module offers a mini-PCIe slot, serial port, wide-range power, and modular expansion. You might wonder why in 2016 someone would introduce a sandwich-style single board computer built around the aging, ARM11 based COM version of the original Raspberry Pi, the Raspberry Pi Compute Module. First off, there are still plenty of industrial applications that don’t need much CPU horsepower, and second, the Compute Module is still the only COM based on Raspberry Pi hardware, although the cheaper, somewhat COM-like Raspberry Pi Zero, which has the same 700MHz processor, comes close.
