How I Invented Linux
12 Jul 2004: Ask anyone that follows technology and operating system currents events who created Linux and Inevitably they would say Linus Torvalds, but if you've read the headlines as of late, there is supposedly reason to believe that Linus was not the true creator. It started with one or two 'real' original developers, then a handful of others and then finally there was a whole herd of 'em. Well you can chalk one more up on the list. osOpinion/osViews editorial contributor, Preston St. Pierre says
Cedega Review: Play Games on Linux
12 Jul 2004: 'Nowadays, the -only- game installed on the XP partition is City of Heroes. I have some games in Linux, but mostly first person shooters (thanks iD and Epic). The XP install is a bare, firewalled install with a City of Heroes icon in the center of the desktop. It's basically an impossibility to do anything long term (torrents, other downloads, maintain conversations via AIM, IRC, play music) if I want to play this (incredibly addicting) game. So I reboot, then reboot back. I'm sure many of
Multi-Layer Intrusion Detection Systems
12 Jul 2004: 'More often than not, single security solutions merely scratch the surface of an entire security event. This surface of information can be equated to the crust of the earth, which only makes up barely one percent of the earth's total mass. Analyzing just this small surface area of event information is not a sustainable approach to protecting networks. One must dig deeper, into the mantle, and even further into the core in order to truly begin to monitor and understand security events within
Zen and the Art of Aspect-Oriented Programming
11 Jul 2004: 'AOP is a new programming methodology that captures and implements crosscutting concerns as modules. Where object-oriented programming (OOP) encapsulates core concerns into a class, AOP encapsulates crosscutting concerns into aspects. An AOP system allows you to implement crosscutting concerns and express weaving, or composition, rules. Another AOP system component, the weaving processing model, realizes the implementation.' Story
SSH Users beware: The hazards of X11 forwarding
11 Jul 2004: 'Enter SSH, a wonderful encrypted remote login/file transfer/port forwarding/you name it protocol. You probably use it when you log into to other Linux machines, such as your shell server, email account, etc. SSH has the ability to tunnel X11 connections through it - this feature is called X11 Forwarding. In brief, if you are on your desktop attached to an X11 display (you can run xclock for example) then when you SSH to a different machine, it can tunnel X11 over the connection. You can r
Embracing strong passwords
10 Jul 2004: 'Strong passwords require eight to 14 characters, minimum, and a mix of case, numbers and symbols. But to a user, strong means more complicated. Users either simplify the password itself or help themselves remember it - often with a Post-It note on the monitor bezel or under the mouse pad. This issue requires human interaction to resolve.'

Bossa, a Framework for Scheduler Development
10 Jul 2004: The recent activity in Linux kernel development caused by the introduction of a new scheduler by Ingo Molnar has emphasized for ordinary Linux users the importance of schedulers in modern operating systems. This article gives you a glimpse of what scheduling development is like by letting you implement your own Linux scheduler thanks to Bossa, a framework for scheduler development.
It's Numbering, but Not as We Know It
9 Jul 2004: 'Like any word processor, OpenOffice.org's Writer automatically adds numbers and bullets to paragraphs for you. Unlike typical word processors, however, Writer does not make lists a part of paragraph styles. Instead, lists have styles of their own. These styles are called numbering styles. It's a rather misleading term, though, because it refers to both numbered and bulleted lists, but never mind.' Story
Novell outlines open-source transition
9 Jul 2004: 'The company will make only minimal investments in its BorderManager VPN and other products in favor of open-source alternatives, as it tries to create a profitable blend of open- and closed-source products, said Alan Nugent, Novell's chief technology officer. Speaking in Boston before an audience of technology experts, systems administrators and open-source enthusiasts, Nugent voiced strong support for his company's decision to bundle its proprietary networking software with open-source p
Blog-City Java garbage collection fix
9 Jul 2004: If you're part of the current blogging craze, then you've likely heard of Blog-City, a blogging site owned and operated by Blog-City Ltd. When some unexpected performance issues cropped up, Java performance experts Jack Shirazi and Kirk Pepperdine(from JavaPerformanceTuning.com) were asked to assist in a technical tuning of Blog-City. Here's what they found out and did to fix the problems.
Beginning C
8 Jul 2004: 'While the introduction to programming material is more common in the early chapters of the book, it doesn't disappear in the later chapters. However, as the book proceeds the emphasis moves much more to the core of the C language. The coverage is very thorough, particularly when compared to a lighter introduction such as C Programming In Easy Steps. Horton doesn't shy away from looking at material often considered tricky, particularly when it comes to pointers. Unlike a number of introduct
Linux helps make weather forecasts more accurate
8 Jul 2004: 'Referring to the humongous simulations that are used in climate research, Zacharia said scientists are benefiting from a good balance of increased processing power and memory, better interconnect technology, a sturdier OS -- Linux -- and advances in mathematical algorithms. 'Without a doubt, we're in a wonderful era with a number of purposeful systems and machines that are entirely focused on the scientific and technical market,' he said. 'I believe computing is going to be the great enabl
Fedora Core 2: Making it work
8 Jul 2004: 'Getting FC2 to a state of desktop readiness is a task that requires a medium amount of skill and will probably take close to a full day for the first workstation (assuming that you have a high-speed Internet connection). Subsequent installs should go more quickly; indeed, I intend for my students to get most of it done during their first three-hour class.' Story
Getting Information From Here to There and Back
8 Jul 2004: An information grid, as defined by this article, is the structure that allows end users and applications to share information, no matter where it is stored. The article shows system architects how to think through the information infrastructure when setting up a grid computing environment.
Whither USENIX?
13 Jul 2004: 'This leads to the more general question: how do we keep the 'practical bias' in academic systems research? Before I try to answer that directly, it's worth looking at the way research is conducted by other engineering disciplines. (After all, one of the things that separates systems from the rest of computer science is its relative proximity to engineering.) To me, it's very interesting to look at the history of mechanical engineering at MIT. In particular, note the programs that no longer
OpenBSD - For Your Eyes Only
13 Jul 2004: 'Given this admirable record, why doesn't everybody immediately run out and install OpenBSD? After all, you can hardly beat the price (free download). Unfortunately, though OpenBSD is free, it does come with a cost. Running an ultra-secure operating system can be a bit of work, and OpenBSD doesn't expend much effort at being user-friendly. In other words, don't expect a point-and-click paradise - OpenBSD will exercise your Unix geek skills more than the typical Linux distro. Indeed, even Fr
How to migrate your company to Linux clusters
13 Jul 2004: 'Anyone following the high performance computing industry has probably noticed the growing popularity of Linux cluster systems. The 23rd Top 500 list, a ranking of the world's most powerful supercomputers, reported that clusters make up more than 50 percent of the list. The appeal is easy to understand; Linux clusters are a fraction of the cost of traditional supercomputers while providing blazingly fast performance numbers. Many organizations from national labs to Hollywood special effects
Safely delete Linux files with libtrash
14 Jul 2004: 'Libtrash is more than a simple utility. It's a shared library that overrides the default actions Linux uses to delete files. Once libtrash is installed, deleted files will be moved into a subdirectory of the user's home directory named Trash. Libtrash allows users to use the normal Linux commands for deleting files, and libtrash will work with any files on the system. ' Story
InstallShield X and Linux
14 Jul 2004: 'It just becomes another way of deploying software, and the secret isn't so much in the package it's how you get to create that package and the quality and consistency of the creation process. So we see RPM and other native delivery mechanisms as just the payload. The secret sauce is in creating that payload, and creating all the logic and dependencies and exception checking around it, to make sure that it does exactly what you want to do. I guess to summarize a short answer to what was pr
The Epson CX5400 All-in-one printer and SUSE
14 Jul 2004: 'It was a simple twist of fate: my HP Scanjet 5200C scanner gave up the ghost at the same time my HP Deskjet 842C ink cartridges went dry. I set off to do some comparison shopping for new cartridges at Office Depot and Best Buy. I decided to check the prices on new scanners as well. Instead of coming home with the best deal on the cartridges, and pricing info on scanners, I came back with an Epson Stylus CX5400. It's a multi-function device that replaces both the HP scanner and the printer,
