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.

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:

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.

  • Minijail: Running Untrusted Programs Safely by Jorge Lucangeli Obes, Google
  • Minijail: Google’s Tool To Safely Run Untrusted Programs
    Google’s Minijail sandboxing tool could be used by developers and sysadmins to run untrusted programs safely for debugging and security checks, according to Google Software Engineer Jorge Lucangeli Obes, who spoke last month at the Linux Security Summit. Obes is the platform security lead for Brillo, Google's Android-based operating system for Internet-connected devices. Minijail was designed for sandboxing on Chrome OS and Android, to handle “anything that the Linux kernels grew.” Obes shared that Google teams use it on the server side, for build farms, for fuzzing, and pretty much everywhere. Since “essentially one bug separates you and any random attacker,” Google wanted to create a reliable means to swiftly identify problems with privileges and exploits in app development and easily enable developers to “do the right thing.” The tool is designed to assist admins who struggle with deciding what permissions their software actually needs, and developers who are vexed with trying to second guess which environment the software is going to run in. In both cases, sandboxing and privilege dropping tends to be a hit or miss affair. Even when developers use the privilege dropping mechanisms provided by the Linux kernel, sometimes things go awry due to numerous pitfalls along that path. One common example Obes cited was trying to ride a switch user function that will drop-root and then forgetting to check the result of the situation relief, or setuid function, afterwards.
  • Intel and Cloudera Give Apache an Open Source Data/Security Tool
    For the past year, we've taken note of the many Big Data projects that the Apache Software Foundation has been elevating to Top-Level Status. The organization incubates more than 350 open source projects and initiatives, and has squarely turned its focus to Big Data and developer-focused tools in recent months. As Apache moves Big Data projects to Top-Level Status, they gain valuable community support. Recently, the foundation announced that Apache Kudu has graduated from the Apache Incubator to become a Top-Level Project (TLP). Kudu is an open source columnar storage engine built for the Apache Hadoop ecosystem designed to enable flexible, high-performance analytic pipelines. And, Apache Twill has graduated as well. Twill is an abstraction over Apache Hadoop YARN that reduces the complexity of developing distributed Hadoop applications, allowing developers to focus more on their application logic. In another Apache-related Big Data move, Cloudera and Intel have announced that they've contributed a new open-source project to the Apache Software Foundation targeted at using Big Data analytics and machine learning for cybersecurity.
  • Twitter Open Sources Stream Processing Engine Heron
    Twitter announced the open sourcing of Heron, a stream-processing engine that is a successor to Apache Storm. Heron is backwards compatible with Apache Storm, which eases its adoption amongst developers. Heron has replaced Apache Storm as the stream data processing engine inside Twitter due to its scalability, debug-ability, ability to work in a shared cluster infrastructure and better performance. A comprehensive list of features is listed in the documentation.
  • Tencent: Transforming Networks with SDN
    “SDN can really transform the way we do networks,” said Tom Bie, VP of Technology & Operation of Data Center, Networking and Server, Tencent, during his Wednesday keynote address at the Open Daylight Summit. The China telecom giant should know about the issues of massive scale networks: they have more than 200 million users for QQ instant messaging, 300 million users of their payment service, and more than 800 million users of their VChat service. Bie noted that Tencent also operates one of the largest gaming networks in the world, along with video services, audio services, online literature services, news portals, and a range other digital content services.
  • The Second Wave of Platforms, an Interview with Cloud Foundry’s Sam Ramji
    In today’s world of platforms, services are increasingly connected. In the past, PaaS offerings were pretty much isolated. It’s that new connected infrastructure that is driving the growth of Cloud Foundry, the open source, service-oriented platform technology. Sam Ramji is CEO of Cloud Foundry, which is holding its European event in Frankfurt this week. At the conference, we spoke with Ramji to discuss, among other topics:

With the Mercurial repository, Sam Lantinga bumped the version in preparation for the SDL 2.0.5 release. The SDL 2.0.5 release hasn't officially happened yet, but it should be here soon.
  • Open standards default at Slovenia supreme court
    The use of open ICT standards is an IT requirement at Slovenia’s Supreme Court, responsible for the IT support of the entire court system in the country. The Supreme Court’s IT department has a strong preference for the development of modular, reusable software solutions. This strategy provides agility and flexibility, says Bojan Muršec, director of IT. The focus on open standards frees up the IT department to concentrate on the business, Muršec says. The IT department takes the modular approach serious: the first reusable module ever developed by the court - a court documents dispatch and delivery system - is re-used by all IT systems across the courts. “Making everything reusable prevents creation of silos in the organisation”, the IT director says. A positive side effect of the IT strategy is that the court uses mostly open source software solutions. This in turn helps to keep IT costs down, says the IT director, who estimates that the court saves EUR 400 to 500 thousand per year on licence fees: “The cost of proprietary licences always goes up.”
  • Why there is no CSS4 - explaining CSS Levels
    We had CSS1, and CSS2. We even had CSS2.1 and we then moved onto CSS3 – or did we? This post is a quick explanation of how CSS is versioned today. CSS versions 1 and 2 were monolithic specifications. All of CSS was included in one massive document. Selectors, positioning, colour – it was all in there. The problem with monolithic specifications is that in order to finish the spec, every component part also has to be finished. As CSS has grown in complexity, and new features are added, it doesn’t make sense to draw a line at which all work is stopped on all parts of CSS in order to declare that CSS version finished. Therefore, after CSS2.1 all the things that had been part of the 2.1 specification were broken down into modules. As the new CSS modules included all that had gone before plus any new features, they all came into being at Level 3. Hence CSS3, and people like me who understood CSS as a single specification referred to the group of Level 3 modules as “CSS3”.

  • Don't Hide DRM in a Security Update
    Over 10,000 of you have joined EFF in calling on HP to make amends for its self-destructing printers in the past few days. Looks like we got the company’s attention: today, HP posted a response on its blog. Apparently recognizing that its customers are more likely to see an update that limits interoperability as a bug than as a feature, HP says that it will issue an optional firmware update rolling back the changes that it had made. We’re very glad to see HP making this step. But a number of questions remain. First, we’d like to know what HP’s plans are for informing users about the optional firmware update. Right now, the vast majority of people who use the affected printers likely do not know why their printers lost functionality, nor do they know that it’s possible to restore it. All of those customers should be able to use their printers free of artificial restrictions, not just the relatively few who have been closely following this story.
  • 6 Ways Driverless Cars Are Going To Kill Lots Of People
    You've probably read a few articles about driverless cars over the past couple of years. The technology is coming along quickly, with fleets of test cars already on the roads in some states. It seems like soon we'll achieve the American dream of stuffing our faces and texting all we want while still managing to avoid public transportation. But the reality is quite different. We're diving into this technology a little too quickly and ignoring all the warning signs about how we are going to screw up on the way to Driverless Car Utopia.
