It’s been almost 200 years since Charles Babbage first started work on his difference engine, and programmable computation is fast approaching 100 years old. Over this time there has been a lot of change in software development and in this article we look at the evolutionary pressure that has shaped that.

The Firefox browser is built using XUL, and the upcoming Firefox 3.0 release will provide a XUL runtime allowing any Firefox user to run any XUL application. In this tutorial, you'll start to program in XUL. You'll see how to leverage your Web development skills to build a XUL-based blog editor. The editor will provide some basic rich text editing, and allow you to save drafts locally that you can reload later for editing.

This week's release of Ubuntu 7.10 "Gutsy Gibbon" is a significant win for the free software community. Not only does this release incorporate an updated package set -- most notably with the Linux 2.6.22 kernel and GNOME 2.20, but it also delivers on new desktop innovations from BulletProofX and displayconfig-gtk to Compiz Fusion being enabled by default on supported systems. However, for those business professionals and gamers that remain dependent on some Windows-only binary applications, the WINE (WINE Is Not An Emulator) project has been making some excellent headway into supporting Windows applications on the Linux desktop. With Ubuntu 7.10 and WINE 0.9.46 in hand, we had set out to compare the performance between Windows XP and Gutsy Gibbon with WINE on two popular DirectX benchmarks.

Java heap areas define objects, arrays, and classes, and Java heap dumps are snap shots of Java heaps at specific times. HeapAnalyzer is a graphical tool that can find possible Java heap leak areas through its heuristic search engine and analysis of the Java heap dump. This technology works on Linux, UNIX, and Windows platforms, and version 2.1 fixes Solaris/HP hprof parser defects.

Fred Trotter has an article in which he discusses Electronic Health Records, the Iroquois Nation's notion of considering the impact of the current generation decision 7 generations from now and Microsoft's HealthVault as well as Google's announced Personal Health Records:

All of the various clients and servers for Enemy Territory: Quake Wars (Community Site) are now available! Thanks TTimo for a job well done as always. You can find all the info you need on the ETQW GNU/Linux FAQ page.

Jaroslav Sykora posted a series of five patches to handle the kernel portion of what he described as "shadow directories", providing an example which utilized FUSE to access the contents of a compressed file from the command line.

Gutsy is running fine -- at times -- on the $0 Laptop (Gateway Solo 1450, 256 MB RAM, 1.3 GHz Celeron). I say "at times" because sometimes power management works, sometimes it doesn't. That part is a bit troubling. It was going fine for awhile, but then I ran a couple of live CDs, some successful, some not (Mepis 6.5, Ubuntu 6.06, DSL 3.3). None of the live CDs ran as well as Ubuntu 7.10, given the latter's superior hardware detection and handling. But after running Mepis (and the live CD probably has nothing to do with it), I rebooted into Ubuntu 7.10 and the fan kept on running. I put the laptop into suspend mode, and when I came out of it, the fan stopped.

Exchanging business cards is a rudimentary form of networking (the people, not the server kind). However, to get the most out of the exchange, you need a card that attracts attention and reflects the image or values you want to project.read more

We often take the ability to choose our default Firefox search engine for granted. By default, it's set to Google, and for most people, this is just fine. But what about queries where a typical search engine is not cutting it?

Thanks to Canonical's System Builder Program, pre-installed Ubuntu Linux PCs are available throughout the world and not just from Dell. Everyone in the Linux desktop world knows that Dell now offers Ubuntu Linux 7.04 on some of its laptops and desktops. Some also know that Dell will soon be offering the latest Ubuntu, 7.10, on its systems. Dell, however, is far from the only PC builder that offers Ubuntu to its customers.

Although Perl-based Web interfaces have limitations, Perl is one of the most commonly used Web development languages. UNIX users who have a programming background in shell scripting, Perl, or another language can breathe new life into Perl-based Web interfaces by using the Perl/Tk module.

Last month I was threatened with police intervention after taking pictures of my two-year-old. Why? We were in what you might think of as analogous to an outdoor mall. It’s a former industrial complex that’s listed in the National Register of Historic Places. Today the area has been revitalized with restaurants and office space, a large greenspace in the middle, and an attractive manmade river and waterfall.

This HowTo will describe the setup of an efficient http server and mail server for small or medium configurations (as low as 96 mb). Why LEMP instead of LAMP? NGINX is a great replacement for Apache with very low memory footprint and great stability.

In the wee hours of the morning, while I was sleeping soundly, all snuggled up next to my wife...

Just how cheap can a fully functioning Linux PC get?

By some ironic fortune, proprietary vendors like Apple and Microsoft will likely always suffer this damnation that their consumer-control inspired proprietary nature always brings with itself: security problems - exactly the thing they claim to prevent by being so control obsessed. You can stay damned with them or you can break free.

How is the third version of the GNU General Public License (GPLv3) being received four months after its official release? Not well, if you believe the Evans Data survey released on September 25. However, those who concern themselves with licensing issues at the Free Software Foundation (FSF) and at Palamida, a company that advises customers on issues that surround free and open software (FOSS), paint a different picture. According to these FOSS experts, adoption of GPLv3 is going as expected, and, while reasons for caution exist, the new version is likely to replace GPLv2 some time in the next few years. As for the Evans Data survey, they suggest that the information released overgeneralizes a complex situation.

OpenOffice.org Base is undoubtedly a powerful database application, but when it comes to its built-in reporting engine, words like "underpowered" and "outdated" come to mind. Fortunately, you don't have to put up with this situation any longer: with the Sun Report Builder (SRB) extension, you can add nifty reporting features based on Pentaho reporting engine -- assuming you can figure out how to use it without any help.
