Have you ever wanted to create an installer program on a Linux system, but didn’t want all the hassle of an actual install builder? I have. So I’m going to show you how you can create such an installer with very little hassle. I can’t actually claim credit for this method though; I actually got the idea from Sun’s JDK installer for the Linux platform. You download a “.bin” file, change the file mode so that it is executable and then run it. It displays the end user license agreement, gets some feedback and then goes about installing Java for you. Well, if you open that .bin file up in a text editor (say vi) you’ll see that it’s nothing more than a shell script with a binary chunked onto the end. Thus my plans for world domination were born…

Previously, we've interviewed the lead-developers of Arch and Gobo Linux. Two distributions for the more advanced users out there. This time, we're going in the complete opposite direction to understand more about a user friendly Linux-distribution: Ubuntu.

Quantum GIS 0.11.0, released last month, is a free geographic information system (GIS) application released under the GPL that runs on multiple platforms, including Linux. QGIS can read, edit, and export common GIS file formats. After installing it and using it to work with existing data layers available from official data repositories, performing common spatial analysis tasks, and sharing files and data with the commercial GIS products, I found QGIS has the potential to be a viable alternative to proprietary commercial GIS programs from the likes of ESRI and Intergraph/Geomedia.

Sun Microsystems has taken another step in its long journey towards greater support of open source by delivering the first beta of its next crop of NetBeans. The NetBeans 6.5 beta builds on the open source integrated development environment's earlier support for dynamic languages with support for PHP.

Students and linguists from Makerere University have translated the open source web browser, Mozilla Firefox, into Luganda at a Translate@thon held on the campus in Kampala, Uganda last week. The two-day gathering brought together almost 200 students and allowed them to make a practical contribution to their language’s presence in the digital age.

The key to IT security is secure software - software that is written with not only features, but also security, in mind, says David Jacobson, technical director at Linux services company Synaq. However, says Jacobson, software is seldom developed with an eye on back-end security requirements. Developers are usually under pressure to deliver on required features within tight deadlines which leave little time to check for vulnerabilities each step of the way. The result is that most software is inherently vulnerable.

Firewall Builder (fwbuilder) is a graphical application that can help you to configure IP traffic filtering. It can compile the filtering policy you define into many specifications, including iptables and various languages used by Cisco and Linksys routers. Separating the actual policy you define and the implementation in this way should let you change what hardware is running your firewall without having to redefine your policy for that platform.

OpenID sounds like a great idea - essentially single-sign on for multiple web sites or web applications, without participating sites having to see your credentials. But is it trustworthy and safe in the light of recent revelations concerning a flaw on the DNS system on which it relies?

In the past, data was structured, secure and tightly controlled. The bad news is that the data was limited by the firewall of personnel, technologies, and process rigidity. Today, however, the demand is for just-in-time and inclusive data, moving away from a monolithic data system mentality to multiple sources of data that provide real-time inferences on consumers, activities, events and transactions.

Community journalism encourages members of the community to participate in the news process, not just as passive readers, but as active producers of the news itself. This direct connection to the product is similar in many ways to the kind of community building that goes on in open source development.

Yes, Nortel Networks acquired Pingtel -- an open source VoIP firm. But the bigger story: Nortel may finally realize it needs to leverage open source communities to combat Cisco Systems. At least that's the spin from The VAR Guy.

We all know the term “FUD“, don’t we? If you haven’t heard of it, it means “Fear, Uncertainty and Doubt”, and it was created a big software monopoly, often headlined “Get the facts”. Some years ago, I got the real facts. And the real FUD.

Wired: Are you going to develop a version of Firefox for the iPhone? Lilly: No. Apple makes it too hard. They say it’s because of technical issues — they don’t want outsiders to disrupt the user experience. That’s a business argument masquerading as a technological argument. We’re focusing on more important stuff. The iPhone has been influential, but there’s not that many of them. We’re part of the LiMo Foundation — Linux on Mobile. The Razr V2 is a LiMo phone, and you’ll see more in the next year or so.

Hiring a well-known free software advocate to oversee efforts to work with the community is a good plan for any company, but for a company that has had rocky community relations, it may be essential. VIA Technologies has done just that, by contracting with Harald Welte to help guide its strategy to work more closely—and less contentiously—with the community. VIA announced a new effort aimed at cooperation with the free software world last April, but got off to a slow start that had people wondering about its commitment to fulfilling that promise. Welte will be well placed to ensure that community concerns are heard within VIA.

In a significant victory of free and open source licences the US Court of Appeals for the Federal Circuit - which deals with IP issues - has upheld an open source licence, in particular referencing the Artistic Licence from Creative Commons.

How to avoid alias recursion loops in any Linux or Unix shell.

youtube-dl is a small free opensource command-line program to download videos from YouTube.com. youtube-dl is a platform independent tool that works on UNIX, Linux, Mac OSX and Windows. The latest version of Youtube-dl is 2008.08.09 and requires the Python interpreter, version 2.4 or later. I’ll try to keep it updated if YouTube.com changes the way you access their videos. After all, it’s a simple and short program.

Ok, more specifically, troff using the mm macros to HTML. This is another from my "rusty scripts" collection which was written for a specific task long ago. In this case, we were converting some internal documentation from troff using the mm macros into HTML. troff is a very sophisticated system so doing this right would be a lot of work. But, writing something to get rid of 90% of the grunt work of conversion is pretty easy. Paul Dunne did one for the ms macro set which you can find here but mm is different.

The communications equipment maker has bought one of its software suppliers, Pingtel, in a deal Nortel claims will help promote open source communications.

Continuing our journey, it's time to take a trip up the OSI Reference Model, and learn what this mysterious thing is all about. The network stack is of great significance, but not so much that it's the first thing you should learn. We've waited to start the "layers" discussion for good reason: Many so-called networking classes will start by teaching you to memorize the name of every layer and every protocol contained within this model. Don't do that. Do realize that layers 5 and 6 can be completely ignored, though.
