The Open Source Initiative still lives

Filed under
OSS

There was a time when the OSI (Open Source Initiative) was one of the hotbeds of open source activity. After the retirement of its co-founder and leader, Eric S. Raymond, in January 2005, the OSI lost much of its fire. That may be changing soon, though.

Small businesses are ripe for free software

Filed under
OSS

Once upon a time, in a career far, far away, I worked for a very small business. I was tasked with upgrading the OLD PC’s. The budget was so miniscule that literally every penny counted. In the effort to get the best bang for the buck, I stumbled across these programs called free software. “Whoo-hoo, they’re free” I thought. Little knowing how that introduction to free software applications would change my life.

There are plenty of misguided projects which people in the West undertake, under the mistaken impression that they are helping those in the underdeveloped regions of the world.

The One Laptop Per Child initiative, a brainwave of MIT's Nicholas Negroponte, is just the latest in a long line. When you throw in fancy phrases like "bridging the digital divide" the publicity is ensured.

Linux: Page Replacement Design

Filed under
Linux

A university student studying operating systems asked about why the Linux kernel uses two chained lists in its LRU (least recently used) page replacement algorithm. Andrea Arcangeli, whose virtual memory subsystem was merged into the 2.4.10 kernel, explained, "back then I designed it with two lru lists because by splitting the active from the inactive cache allows to detect the cache pollution before it starts discarding the working set."

Test of current RealPlayer/HelixPlayer nightly builds

Filed under
Software

After I wondered what the current state of the HelixPlayer/RealPlayer development is I asked the developers. The answer was that there is still no date given, but that I could help them by testing the players in my setup. And since that isn’t difficult at all I downloaded the rpms and gave them a try.

Leftovers: OSS and Sharing

  • 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

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.

  • 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.
