linuxtag-reporter writes "The first day of LinuxTag, Europe's biggest Free Software event (expecting 25,000 visitors) already has one big highlight. It seems that Fabian Franz from the Knoppix Project hacked up a 'FreeNX Server' based on NoMachine's NX technology (poor NoMachine might lose business now). Fabian Franz presented a first preview of the 'GPL Edition' in a live demo together with Kurt Pfeifle. The demo showed sessions going from Germany to Italy just based on a slow WLAN connectivity (shared with hundreds of visitors). A connection lost due to bad network conditions was easily re-connected to, and a deliberately suspended session was revitalized too -- it was just like 'screen' with a GUI! A report on the official LinuxTag webpage says FreeNX will be publically released for the first time as part of the upcoming Knoppix-3.6 release. The Kalyxo project is building and hosting Debian packages of FreeNX and NX/GPL for everyone to use."

norburym writes "This is not an intro Linux book for your mom. Well, actually it's an intro Linux book for the author's mom! Linux for Non-Geeks came about by virtue of Rickford Grant's desire to create an easy to follow guidebook to installing, configuring and using Linux for his mom who, at 72, was on a fixed income. Her erstwhile son suggested giving her an old box of his with Linux installed. Willing to go along, she asked for book suggestions to learn about Linux. Stumped by the meager offerings, Grant decided to write up a set of instructions on his own. Egged on by relatives and friends to subsequently publish his manuscript, Penguinistas the world over can now rejoice! A far cry from dumbed down editions of how-to comic book style manuals from other publishers, No Starch Press has adopted a smart series of books for the capable, no nonsense audience; those folks who are not afraid to try new things and who want a clear and (more importantly) practical approach to enhancing their skill set. This book is a stand out in that series." Read on for the rest of norburym's review.

An anonymous reader writes "In More Power To The Firmware Amit Singh talks about technical details of EFI, the next-gen BIOS replacement standard Intel, Microsoft and others are pushing. This is a very informative piece where he talks of issues with legacy BIOS, how it affects those who develop in the firmware environment and how EFI plans to solve these problems. EFI usage examples are included, including a programming example. He contrasts EFI with Open Firmware as well. IMO the second half of the article is even more interesting, where sample FORTH code is provided for displaying a window/mouse pointer GUI inside the Apple/Mac firmware! And of course, there's code for a new 'Towers of Hanoi' animation using the Mac firmware (remember Hanoimania?). Aspiring Mac Firmware Hackers could also check out the suggested projects ;-)"

Poizon writes "The guys from freehackers.org have begun developing yet another vi-like editor, called Yzis (speak: "Why this?"). Their primary goal is to seperate the text processing engine and the GUI, in order to be able to integrate it into window managers like KDE as a native component. They have previously worked on KVim, a Vim port to KDE, so chances are good that they will succeed with Yzis. Sounds interesting, doesn't it?"

Two strongly contrary claims describe the usability of Unix and Unix-like operating systems. Roughly, these claims go like this: 1) "Unix is easy! With a few simple commands you can navigate the filesystem and manipulate text; for the rest, just read the fine manual." That's the viewpoint (painting with a broad brush) of technically literate technojunkies. 2) "Unix is a pain. Cryptic commands, confusing explanations -- when I can get them -- from my smug cousin Jim. And where is this so-called manual?" That's the viewpoint (same broad brush) of a lot of people who -- let's say -- aren't the ones rushing to upgrade their heatsink and overclock their RAM, but have given things Unixy a spin. Linux for Dummies has been around long enough to reach its recently published 5th edition (written by Dee-Ann LeBlanc); it aims to bridge the 'Way too Hard!' and 'All Perfectly Easy' schools of thought. Read on for my review of the book.

baxissimo asks: "I've played around with Python a bit, and as a scripting language I quite like it. So I sat down the other day to see if I could use it to make a modest OpenGL/GUI application on Windows. The short story is I gave up. I couldn't get the Python IDE I had to run--but that didn't stop me. At first I just shrugged my shoulders and said to myself 'Ah, who needs it? I've got emacs,' and then proceeded to waste a few hours trying to cobble together an app that would run before it dawned on me that Python without a decent IDE is definitely not easier to use than C++ with an IDE. So is anyone out there actually using Python to make serious apps? What tools are you using?"

FTL writes "Tim Robinson has built a computer capable of solving polynomial equations -- using Meccano. His difference engine (mirror) uses a similar approach to Babbage's design. He's also created a differential analyzer (mirror) complete with a GUI. Both could be scaled up indefinitely to handle larger problems. 'Computing by steam' is possible."

ubiquitin writes "Existence of the Secure Architectures with OpenBSD text was first made public on the OpenBSD Journal in early April 2004. The OpenBSD Journal, also known as deadly.org and now undeadly.org, recently changed hands from James Phillips to Daniel Hartmeier amid several more or less obscure references to Pogues lyrics. The peaceful transfer of the site is a good thing, as it means that the several-hundred articles posted to the journal will remain in publicly-accessible archives for the foreseeable future and the occasion gave Hartmeier, known for his development of packet filtering (pf) and network DVD playing (kissd) software, a reason to try his hand at building a content management system. Jose Nazario is both an author of the book under review here and a contributor to the OpenBSD Journal web site, which seems to be a watering hole for unix hackers, having something of the flavor that Slashdot had in the late nineties." (Jose is also an occasional Slashdot book reviewer, and a good cook.) Read on for the rest of ubiquitin's review.

Eugenia writes "Many in the F/OSS community are raving about the Gimp, however pros who have actually used Photoshop think differently: This Mac professional designer goes through the steps of getting Gimp 2.0 up and running on his Mac, only to get baffled by the chaotic interface in general and its non-standard UI compared to other Mac apps, its slowness to open large files and to apply filters, the unintuitive tools that accompany it and its very visible bad quality of text and lines/shapes. That designer even bought a 'supported' version of MacGimp by an OSS-Mac company, Archei, but he never heard back for his support requests (free Gimp for Macs here). I think that's one of the best-written articles I've ever read about the reality of most open-source geek-driven projects vs their equivelant professional/proprietary ones. Personally, before I get persuaded to use Gimp again for my photography projects, I would need --in addition to the author's peeves -- full 16-bit per channel support, high-quality scanning/printing drivers with integrated GUI (a'la SilverFast), and a 'crop and rotate' feature (as seen in PS/PSE). Besides, both Paint Shop Pro and Photoshop Elements cost bellow $100 (with PS Elements getting bundled with most scanners/printers/digital cameras, albeit without the much needed 16bit support either)."

honestpuck (Tony Williams) writes "Many years ago I bought a second hand Ford Cortina in dubious condition. I kept it running with the assistance of a marvelous volume purchased at a specialist bookstore that was referred to as "the shop manual." It wasn't much help teaching you how to drive or how to park but if you needed to know how to perform an oil change, flush the radiator or bleed the brakes it told you all the details. Now James Duncan Davidson has given me a shop manual for Macintosh OS X Panther." Read on for Williams' review of the O'Reilly published Running Mac OS X Panther. (And for the curious, here's what google has to say about "Ford Cortina.")

Jaap Geurts asks: "With the 3D GUI desktop around the corner, nobody seems to use or think about text based user interfaces (TUI) anymore. I know that hardware comes cheap nowadays but can the use of TUIs still be justified? I've always found that GUIs are resource hungry, generally slower and more importantly they often allow multitasking and they are very unpleasant without a mouse! What do you think about developing a (well designed) TUI for DB software (e.g Point of sale, Warehouse manager, etc)? Most current GUI metaphors can be implemented so what are the pros and cons from a user perspective?" Are there any real reasons against deploying text-based applications, today?

Karma Sucks writes "In 'A Taste of Qt 4', Trolltech reveals that it is positioning Qt 4 directly against Java. Qt 4 promises to be smaller and faster than its predecessors and there will be a boatload of new features including support for non-GUI applications and accessibility under Linux using Sun's ATK. More controversial is the introduction of a new and elegant foreach construct. Incidentally, for those still opposed to Qt's moc preprocessor, Havoc has some interesting comments. It is possible the idea will be adapted to provide GObject introspection in the future."

Cypherus writes "I came across a link for a 3d desktop environment. "The SphereXP is a 3D desktop replacement for Microsoft Windows XP. Taking the known concept of three-dimensional desktops to its own level. It offers a new way to organize objects on the desktop such a icons and applications. Check the videos and screenshots to get the idea.""

nazarijo writes "I look at packets for a living. I generate them, I capture them and dissect them, and I try and make sense of them as quickly as possible. Sniffers and protocol analyzers are part of my bread and butter, and I'd be foolish to not use Ethereal. Tcpdump for a quick capture, but I use Ethereal when I need detailed information in a better, more navigable fashion. Because of that, I was pretty interested to see a book on Ethereal coming out." Read on for Jose's review of Ethereal Packet Sniffing from Syngress.

anomalie asks: "I am trying to sell IP telephony to my employer. The idea was shot down once already because of the cost (using a Cisco solution). I would like to find a cheap but reliable IP PBX because everyone liked the idea of IP telephony, just not the price associated with it. I need a system that could initially handle about 80 users at a single location, and eventually handle about 350 users at 7 locations. The two systems I have been looked at so far are Asterisk & Pingtel's SIPxchange IP PBX. I'm not looking here for a final solution, just some starting points for more research. Any feedback/tips/warnings from the Slashdot community?"

soblasted writes "With the recent 2.0 release of the Metasploit Framework, people are wondering if security tools like it do more good than harm. This article attempts to answer the question. The legitimate use of the framework is for security researchers to use in exploit testing and development.It will run on any OS with Perl, and includes a CLI and web GUI, along with many ready to run exploits and payload modules. With HP also developing systems to preemptively attack their own networks, has this become acceptable?" This issue reminds me of the first release of SATAN and the uproar it caused.

Several folks submitted the press release announcing the formation of the X.Org Foundation and the release of X11R6.7 of the X Window System. The XOrg Foundation is the successor to the X Consortium, formed by many of the most notworthy participants in the XFree86 Project. This code release is a tree forked from the last XFree86 release not troubled by that pesky license change. Since Mandrake, Gentoo, OpenBSD, and Debian have already rejected the new XFree86 license, this new code tree will likely become the default X11 for most Linux users. I've attached the press release that explains more details about the code release, as well as the X.Org foundation itself.

Kristian - Dreamless writes "Wanting to war drive with style? The other day I surfed the web to find a free dash pc solution to my car since the commercial ones cost around 2000-2500$ here in Denmark. I found DashPC.com and I must say this looks promising a very nice GUI and the features seems to be endless: Navigation with War driving, Multimedia and so on. Requirements? Low cost pc and a dash LCD display."

ImmO writes " The eXtreme Computing Research (XCR) group at Louisiana Tech University is pleased to announce the first public release of HA-OSCAR 1.0 beta. High Availability Open Source Cluster Application Resource (HA-OSCAR) is an open source project that aims toward non-stop services in the HPC environment through a combined power of High Availability and Performance Computing solutions. Our goal is to enhance a Beowulf cluster system for mission-critical applications and downtime-sensitive HPC infrastructures. To achieve high availability, component redundancy is adopted in HA-OSCAR cluster to eliminate single point of failures, especially at the head node. HA-OSCAR also incorporates a self-healing mechanism; failure detection & recovery, automatic failover and fail-back. The 1.0 beta release supports new high-availability capabilities for Linux Beowulf clusters based on OSCAR 3.0 It provides an installation wizard GUI and a web-based administration tool that allows a user to create and configure a multi-head Beowulf cluster. A default set of monitoring services are included to ensure that critical services, hardware components and important resources are always available at the control node. "
