Inadvertently Proving the Opposite by Knocking Down a Strawman

In How Far Behind is Linux?, WSJ writer Lee Gomes sets up a beautiful strawman about the security of GNU/Linux versus Windows and knocks it down with its own answer.

Where does Linux go from here?

Linux is now mainstream -- so mainstream, in fact, that two of the top three Linux distributions are commercially successful operations, and the third aims to be. Every day, more and more old-school IT firms shake off their initial doubts, get in line behind their customers, and try Linux and other free software projects. In the face of such success, will Linux remain true to its free software ideals and to the community which created it? Or will it morph into a corporate byproduct, driven by the bottom line, and complacent with all forms of predatory intellectual property (IP), including software patents and closed, proprietary standards which are standard fare in the IT industry.

This week at LWN: Memory part 3: Virtual Memory

The virtual memory subsystem of a processor implements the virtual address spaces provided to each process. This makes each process think it is alone in the system. The list of advantages of virtual memory are described in detail elsewhere so they will not be repeated here. Instead this section concentrates on the actual implementation details of the virtual memory subsystem and the associated costs.

Of opposable thumbs and software engineering

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.

Build an XUL-based Blog Editor

  • IBM/developerWorks; By Michael Galpin (Posted by IdaAshley on Oct 20, 2007 7:51 AM EDT)
  • Story Type: News Story; Groups: IBM
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.

Ubuntu 7.10 + WINE vs. Windows XP

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.

Find Java Heap Leaks with HeapAnalyzer

  • IBM/alphaWorks (Posted by IdaAshley on Oct 20, 2007 4:00 AM EDT)
  • Story Type: Tutorial
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.

The Trotter Test: EHR/PHR Lasting Seven Generations

Shadow Directories

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.

Ubuntu 7.10 Gutsy -- first impressions on the $0 Laptop

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.

Creating business cards with Writer

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 more

Open Source, Firefox and New Search Options Emerge

  •; By Matt Hartley (Posted by gsh on Oct 19, 2007 10:17 PM EDT)
  • Story Type: Editorial; Groups: Linux
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?

The wide world of pre-installed Ubuntu

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.

Learn the basics of the Perl/Tk module

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.

(Mis)understandings of the words “intellectual property”

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.

How To Install A Complete LEMP (Linux - EngineX (Nginx HTTP SERVER) - Mysql - PHP) Server On Ubuntu/Debian
