LWN.net Weekly Edition for August 21, 2003The Xouvert project[This article was contributed by Joe 'Zonker' Brockmeier]
After the much-publicized controversy earlier this year
The Xouvert project (pronounced "Zoo-vaire") is looking to allow developers to add driver support and new features to XFree86 in a modular fashion that should be easy to track and re-apply to the official XFree86 tree. One complaint raised by Keith Packard, and others, is that it has been difficult for developers outside the core team to contribute to XFree86. Xouvert project coordinator Jonathan Walther says that a main goal of the Xouvert project is to make it easier:
We want to lower the barrier to entry to contribute to X. That means not
only being completely open in our source, but also doing other things.
For instance, we use the arch revision control system instead of CVS,
because this significantly lowers the barrier to participating. Anyone
can come along, download our sources, then start committing their
changes locally, keeping the sources under revision control, then at
some later point knock on our door and say "hey, I've got this great new
feature, please merge it back upstream" and it will be a snap, no
history will get lost.
Xouvert is being hosted on Savannah, though it's not an official GNU project. The project is not officially connected to XFree86 either. Walther says that the only communication between the XFree86 team and the Xouvert team, thus far, was when David Dawes "asked us to capitalize XFree86 correctly" and indicate that XFree86 is a trademark. Walther says he'd like to work with the XFree86 team in the long run, however.
Over time as we prove ourselves, we hope to have more communication with
the XFree86 team, and hope to be able to work closely with
them...Xouvert is interested in accepting code from any of the XFree86
developers, whether current or former.
The project is designed so that it is both easier to contribute to, and easier to download and install. Walther mentioned that compiling XFree86 has "often been a source of frustration," so Xouvert's Cameron Berkenpas is working on a HOWTO to make it easier on users looking to compile their X server from source. Walther also says that the Xouvert lead developer, William Lahti, is working on a developer's handbook that will cover Xouvert's overall architecture and API's, though it may not be ready until the second stable release. Right now, there's no real difference between the XFree86 codebase and Xouvert's. Users eager to see the first release of Xouvert don't have too long to wait -- the first release is slated for October 1, and stable releases are expected every six months after that. According to Walther, the first release will only contain "small additions and changes" but the second release next April should contain more comprehensive changes like the DRI/DRM and Utah-glx projects. New projects often fizzle before they reach maturity, so it's too soon to say whether the Xouvert project will become a mainstay of the Linux and open source community. However, given the importance of a free X Server to the long-term (and short-term, for that matter) health and success of Linux, one hopes that the project will be successful.
No escape from SCOHere at LWN, we start each week in the hope that we'll be able to keep SCO off the front page. Each week, the company finds some way to make that impossible. This time around, there are two separate episodes which require attention, and thus two articles to look at them.First, we look at the interesting claim from SCO's lawyers that the GPL is not enforceable, since it is preempted by federal copyright law. This would appear to be a very difficult argument to back up, as has been established by a number of people. But a sinister agenda may yet lurk behind this goofy attack on the GPL; it bears watching. Then, of course, there is our article on SCO's disastrous (for them) demonstration of "stolen" code. This article is responsible for the busiest day LWN's server has ever experienced. As this Weekly Edition goes to "press," this situation is still developing. SCO has not, yet, managed a response beyond the one they sent to us:
Attendees at SCO's annual conference, SCOForum, were shown samples
of Linux code that were illegally copied from SCO intellectual
property. Some Linux proponents are suggesting that SCO has no
claim to this code.
Chris Sontag, GM and SVP of SCOsource, said that not only are their assertions incorrect, but the code is absolutely owned by SCO. In fact SCO knows exactly which version of UNIX System V the code came from and which licensee was responsible for illegally contributing it to Linux. Look for the inevitable "Chris and Darl" teleconference in the near future. It is worth noting that the inclusion of BSD-licensed code into the Linux kernel without the accompanying copyright notice is, indeed, a copyright violation. It is something that absolutely should not be done; in cases where it has happened, it needs to be fixed. We need to take greater care with the licensing of code that we use. But this has never been SCO's point. You don't hire brand-name lawyers over a missing attribution; a simple "please restore my copyright" email will do. A missing attribution does not justify billions of dollars in damages, or even a $699 license fee. There may well have been a copyright violation when BSD-licensed code was used without attribution. But SCO has managed to undermine its own case anyway. (For more information on SCO's Las Vegas slide show, see this article by Bruce Perens, who gained access to the full set of slides presented there).
Aiming at the GPL?It is time to have a look at some statements by Mark Heise of Boies, Schiller, & Flexner - SCO's outside law firm - which were initially reported in the Wall Street Journal and extensively repeated thereafter. According to Mr. Heise, the General Public License (GPL), under which the Linux kernel (and much other code) is licensed, is invalid because it is preempted by federal copyright law. The problem, it is said, is that the GPL allows unlimited copying of the software it covers (as long as its other terms are met) while federal law only allows the creation of a single copy for backup purposes.This is a breathtaking bit of legal reasoning. In one quick blow, Mr. Heise has blown away every free software license, every proprietary site license, and many other end user agreements that have been made over the years. We tried to discuss Mr. Heise's pathbreaking legal work with him, but he didn't feel the need to return our phone calls. So let's just have a quick look at the law he is talking about. The relevant bit of law is section 117 of the U.S. copyright law. It reads (in part):
§ 117. Limitations on exclusive rights: Computer Programs
(a) Making of Additional Copy or Adaptation by Owner of Copy. -- Notwithstanding the provisions of section 106, it is not an infringement for the owner of a copy of a computer program to make or authorize the making of another copy or adaptation of that computer program provided:
In other words, the "backup copy" language is an additional right granted to users of copyrighted material. Nothing in the GPL attempts to restrict this right. The biggest danger posed by Mr. Heise's argument would seem to be the potential for contempt of court findings against those who are unable to control their laughter. (See this article by Eben Moglen for a more complete demolition of the preemption argument). Bizarre statements out of the SCO camp are nothing new. But we should not let the clownish aspect of the SCO Group take attention away from what, increasingly, appears to be part of their real agenda: an attack on the GPL. Consider the latest from CEO Darl McBride, as reported in eWeek:
"In a nutshell, this litigation is essentially about the GNU
General Public License and all it stands for. That license has not
yet been challenged or tested in court, but it is now going to
be. We are also firmly and aggressively challenging the notion that
Linux is a free operating system," McBride said.
The "GPL and all it stands for" has made life difficult for SCO, and they want to take it out. The GPL stands for software which is free, software which is under the control of no company - not even SCO. It stands for a world where nobody can collect large taxes for the concept of "Unix-like systems on commodity hardware." The SCO Group evidently sees such taxes as its birthright. No wonder it wants to destroy "the GPL and all it stands for." This campaign is off to an amateurish start, but it may not stay that way. It bears watching. The GPL is strong, and so are its defenders; it is telling that, over the better part of twenty years, nobody has thought it worthwhile to challenge the GPL in court. The GPL will almost certainly prove far stronger than SCO. But every trip to court has its dangers, and the community cannot affort to be complacent with this one. If SCO follows through on its rhetoric, we have a big and important fight ahead of us.
Why SCO won't show the codeAt SCO's annual reseller show, the company's executives put up a couple of slides as a way of demonstrating how Unix code had been "stolen" and put into Linux. The two slides were photographed and have since appeared on Heise Online; see them here and here. The escape of these slides has allowed the Linux community to do something it has been craving since the beginning of the SCO case: track down the real origins of the code that SCO claims as its own. The results, in this case, came quick and clear. They do not bode well for SCO.The code in question is found in arch/ia64/sn/io/ate_utils.c in the 2.4 tree. It carries an SGI copyright. It seems that SGI was not entirely forthcoming in documenting the source of its source; some of the code in question was, indisputably, not written at SGI. So where does it really come from? This code is from sys/sys/malloc.c in V7 Unix. It has been widely published; among other things, it can be found in Lion's Commentary on Unix (if you can get a copy). It was featured in this 1984 Usenet posting. And, crucially, it has been circulated with the V7 Unix source, which was released by Caldera (now the SCO Group) under the BSD license. SCO would like the world to forget about that release now, but the Wayback Machine remembers. So...SCO's code demonstration, the one that it put up to convince its resellers of its case, comes from a version of Unix which first came out in 1979. The code was publicly circulated in the 1980's, and explicitly released under the BSD license by [the company now known as] SCO at the beginning of 2002. SCO might well have a complaint that SGI did not properly give credit for the code it used. But there is no possible way the company can argue that this code's presence in Linux is an infringement of its copyrights. And this, of course, is why SCO refuses to show the code that, it claims, is copied. These claims do not stand up to even a few hours' scrutiny on the net. SCO may yet have an interesting contract dispute with IBM, but, from what we have seen so far, its claims of direct copying of code are hollow. (Many thanks to those who commented on an earlier LWN posting on this subject - those comments are the source for just about everything that appears in this article. Many thanks are due to LWN's readers; you have shown the best of what the community can do. Update: see also: this analysis of SCO's code by Bruce Perens.)
Security Brief items On the value of virus notificationsMany readers will, by now, be familiar with the results of "SoBig," this week's worm afflicting Microsoft systems. This worm, by some estimates, is accounting for some 70% of all email traffic on the net as this article is being written. Even those of us smugly running Linux, and who are thus not directly susceptible to this worm, have been affected by the flood of incoming email.Interestingly, here at LWN we might have remained almost unaware of this worm. SpamAssassin does a perfectly fine job of filtering out SoBig mail; it never made it to our mailbox. The same cannot be said for the steady stream of "your email contained a virus" mail which continues to pour in. Finding our real mail among all of the virus notifications has become a bit of a challenge. The thing is, of course, that we have not sent infected mail to anybody. Honest. Neither have many of the other people who have gotten these notifications. The software sending these notifications is working on the assumption that email containing virulent malware will also be so polite as to contain a correct return address. SoBig is far from the first infestation which forges return addresses, and it will certainly not be the last. If virus notification email ever served a purpose, it has long since outlived it. Virus/worm scanning software has its place in organizations which are running vulnerable software, but as soon as it starts sending mail to addresses found in hostile mail, it becomes part of the problem. If you have anything to do with the development, deployment, or administration of such software, please consider turning the notification feature off.

Resources August CRYPTO-GRAM newsletterBruce Schneier's CRYPTO-GRAM newsletter for August is out. It looks at airline security silliness, hidden text in documents, and Bruce's new book. "If I can name one overarching goal of the book, it's to explain how we all can make ourselves safer by thinking of security not in absolutes, but in terms of trade-offs -- the inevitable expenses, inconveniences, and diminished freedoms we accept (or have forced on us) in the name of enhanced security."
CERT Advisory on GNU FTP server compromiseCERT has issued an advisory on the compromise of the GNU FTP server. "Because this system serves as a centralized archive of popular software, the insertion of malicious code into the distributed software is a serious threat. As the above announcement indicates, however, no source code distributions are believed to have been maliciously modified at this time"

Page editor: Jonathan Corbet Kernel development Brief items Kernel release statusThe current development kernel is 2.6.0-test3; no development kernels have been released over the last week.-test4 must be getting closer, however; Linus's BitKeeper tree includes several hundred patches, including numerous networking fixes, a new free_netdev() method for networking drivers, a new cpumask_t type for systems with more processors than bits in a long integer, a CONFIG_BROKEN option to control access to drivers known to be broken, a magic, fast new strncpy() implementation, the addition of wireless statistics to sysfs, Twofish and Serpent support for IPSec, the beginnings of Patrick Mochel's power management merge, new sysfs attributes to control scanning of SCSI devices, a number of IDE patches, a new sysfs "attribute group" mechanism which enables the addition of attributes in a safer way and with less boilerplate code, and a mind-numbing array of other fixes and updates. The current stable kernel is 2.4.21; Marcelo has not released any 2.4.22 release candidates since 2.4.22-rc2 on August 8.
Kernel development news Alan Cox goes on sabbaticalAlan Cox, a crucial figure in kernel development since, almost, the beginning, has announced his intention to take a one-year sabbatical from Red Hat and "vanish" from kernel development. He has, apparently, decided to don a tie and go back to school for an MBA. "A few years ago I'd have worried about doing this, the great thing is that with the kernel community we have today I know I'm not a critical cog in the machine. In fact I'm surrounded by people far better than I am and we even have Andrew Morton to keep Linus in check 8)" He'll be around until the end of September. Most of his current projects have been dropped or passed on, but there is an opportunity for somebody who would like to maintain the 2.2 kernel...
The end of /proc/kcore?Russell King recently posted a patch which makes Linus's kernel tree build properly for the ARM architecture. One of the remaining issues, it seems, was getting /proc/kcore to work. /proc/kcore, of course, is a virtual file which appears to be a core image of the running kernel. It can be used to run debuggers on a running kernel to dump out data structures and such.The problem with /proc/kcore is that it has to handle loadable modules, which are placed in address space that is separate from the rest of the kernel. Providing user-space access to that space is easier on some architectures than others. ARM, it seems, is one of the harder architectures to support. So, rather than put in large amounts of effort to produce an ugly solution, Russell simply threw in the towel and decreed that /proc/kcore would not be supported on ARM - at least, in the absence of a volunteer to take on the work. Linus responded by suggesting that /proc/kcore be removed for all architectures.
Does anybody actually _use_ /proc/kcore? It was one of those "cool
feature" things, but I certainly haven't ever used it myself except
for testing, and it's historically often been broken after various
kernel infrastructure updates, and people haven't complained..
There were a couple of followups from people who occasionally use it, but a notable lack of impassioned defenses for /proc/kcore. The biggest problem, perhaps, is that OProfile uses that file for some information, but there suggestions for small changes in how OProfile works to get around that problem. Unless somebody comes up with a stronger argument soon, /proc/kcore is likely to be history.
User-data replication on NUMA systemsNon-Uniform Memory Access (NUMA) systems have the interesting feature that access times to memory vary from one node (group of one or more processors) to another. Each node has local memory, which is relatively fast, but access to another node's memory will be slower. So performance work on NUMA systems tends to emphasize getting rid of cross-node memory traffic.The latest step in that direction is this patch from Dave Hansen. Dave notes that one source of cross-node traffic is shared user text - things like shared libraries and executible images. Once a particular page from, say, glibc has been faulted into memory, it will exist in a particular node's range. Every other node will have to reach across the system to run code out of that page (though processor caches also figure into this picture, of course). In some cases, such as with the C library, it may well make sense to make a local copy of each page as needed. To that end, Dave's patch makes some fundamental changes to the kernel's page cache. This change is required, since the cache can now contain more than one memory page for each corresponding file page. So the page cache now contains a set of page_cache_leaf structures, the main component of which is a per-node array of struct page pointers. A page cache lookup will preferentially return a node-local copy of the page if it exists; depending on the situation, it can return a page on a remote node if that's all that is available. When the kernel handles a page fault for a mapped text page, it insists on a local copy of the page. If no such copy exists, and memory is available, a local copy will be made and added to the page cache. The processor then continues with its work, using the local version of the shared page. The results, from a set of quick benchmarks posted with the patch, is a performance improvement of 109% to 143%. In other words, it may well be worth the trouble. This patch is not quite ready for prime time, however; Dave notes:
This is still pretty experimental, so don't give it to your bank or
anything. I've lightly corrupted data playing with it, although
not in at least a week :)
The current code punts on a couple of important issues. When a process tried to write to a file with replicated pages, for example, those pages must be collapsed down to a single copy before the write can be allowed - or inconsistent copies will result. Similarly, if the last writer closes a file, that file suddenly becomes a candidate for replication. The patch, as posted, detects these situations but does not fully implement their resolution. A production-ready patch would also certainly have a mechanism for freeing replicated pages when memory gets tight. Given that this patch is clearly not 2.6 material, however, Dave has a long time to work out those details.
Harping on ARPOne of the longer-running current discussions on linux-kernel (and linux-net, and netdev) was started on July 27, when Bas Bloemsaat pointed out a problem that he was having. The Linux implementation of ARP, it seems, it not working as he would like.ARP, the Address Resolution Protocol, is the means by which IP addresses are translated to physical layer MAC (usually ethernet) addresses. ARP makes local area networks work by enabling systems to find each other. When one system has a packet to transmit to another on the local network, it broadcasts an ARP request packet seeking a MAC address for a given IP address. Some machine (usually the intended recipient) hopefully responds with the corresponding MAC address, and the packet gets sent. If a Linux system (with a default configuration) receives an ARP request on one of its interfaces, and that request is looking for an IP address assigned to any of the systems interfaces, the system will respond to the ARP request through the interface that received it. This response happens even if the interface involved is not the one to which the requested address has been assigned. Mr. Bloemsaat's problems came about because his system has two interfaces plugged into the same network. Both interfaces receive - and respond to - ARP requests sent on that network. Depending on the order in which the responses are sent, traffic could be directed to the wrong interface. Mr. Bloemsaat included a patch which restricts ARP responses to the interface actually implementing the requested address. But, over almost a month of discussion, the networking hackers have made it clear that they do not intend to change the way Linux behaves. Their reasoning follows, more or less, these lines:
A lot of the confusion, it seems, comes down to a subtle difference in how systems handle IP addresses. Many (perhaps most) networking implementations treat addresses as "belonging" to the interfaces they are assigned to. With that view of the world, no network interface has any business responding to an ARP request for an address which is assigned elsewhere. Linux, instead, sees IP addresses as a property of the system as a whole. So it makes sense for an interface to respond to a request for one of the system's addresses, even if that address is normally associated with a different interface. The networking RFCs make it clear that either view of IP addresses is legitimate. Armed with that, and their sense of how things should work, the networking hackers are determined to keep Linux's ARP behavior as it is.

Page editor: Jonathan Corbet Distributions News and Editorials BRLSPEAK and Oralux - Distributions for Visually ImpairedBRLSPEAK and Oralux are two specialist Linux distributions catering for our less fortunate friends and colleagues who happen to be blind or otherwise visually impaired. But even if you have a perfect 20/20 vision, it is worth taking a closer look at these projects - they are not only enormously useful, they are great fun too!BRLSPEAK www.brlspeak.net is a project started by Osvaldo La Rosa some 3 years ago. The author is visually impaired and since he also happens to be a great fan of GNU/Linux and Free Software, he decided to create a mini Linux distribution for those who suffer from similar disabilities. From the author's web site: "Too many blind computer users believe that only Microsoft operating systems are accessible for them with braille or speech - this is not the case! There are alternatives, and one of them is GNU/Linux. If you are looking for a free, powerful, blind-friendly, stable, open source, network-enabled, multi-tasking, multi-user and command line-minded operating system, then you must absolutely learn about GNU/Linux!" BRLSPEAK is a mini Linux distribution (the size of the downloadable ISO image is only 36MB) with two objectives. Firstly, it has been designed in such a way that blind persons can install it without any outside assistance, and secondly, they should be able to pre-configure and compile the braille drivers all by themselves. These drivers will be immediately operational upon boot. All stated goals were achieved in November 2001 and BRLSPEAK version 7.0 was released later that month. It was based on Slackware's ZipSlack (hence the inflated version number), which can be installed in a directory on a DOS file system (no hard disk partitioning is necessary) or a ZIP drive. A new beta version, several related utilities, as well as a repository of pre-compiled braille terminal drivers are currently under development. Oralux www.oralux.org is a recently launched project, first announced in July 2003. The distribution's web site does not provide much information about the project origins or its authors, but it does have a fair amount of useful documentation in the form of FAQs. Its major advantage over BRLSPEAK is that it runs directly from a bootable CD and no installation is required. It is based on Knoppix, with the usual excellent hardware auto-detection and immediate availability after boot. The size of the downloadable ISO image is under 400MB. Booting Oralux is half the fun. After the obligatory hardware detection and configuration, the user is greeted with the sound of a cockerel, the distribution's official logo, which gives the user an opportunity to adjust speaker volume. The next step is the language selection with English as the only supported language in version 0.04 (courtesy of the Flite synthesis engine), although future releases might include Spanish and German, if there is sufficient demand and enthusiasm to contribute to the project. This is followed by a keyboard selection and a chance to install DECTalk, a popular commercial application with support for English and French, which some users might have available on their hard disks. All instructions are given in a surprisingly clear and crispy voice. As soon as the initial configuration is completed, the users find themselves in Emacspeak. Emacspeak is a complete audio desktop, a speech interface that allows visually impaired users to interact independently and efficiently with their computers. This is a very simple definition and it would be more accurate to say that Emacspeak is a massive suite of dozens of speech-enabled applications. The range is quite astonishing and it includes multimedia control tools, authoring and productivity applications, and even development tools and games. Fancy a speech-enabled front-end to ssh? Or editing support for Perl with aural highlighting and access to online help? Or a spreadsheet application with support for customizing spoken feedback on a per-sheet basis? Yes it's all there. Also included is a simple, but standards-compliant w3 web browser and vm mail reader with full mime support. It goes without saying that the usability of many of these applications depends on external factors. One of the more important ones is the skill of the user to navigate Emacspeak and those who are already familiar with Emacs and its commands will have a substantial advantage. But those who are not do not need to despair. A few essential commands are given right within the initial screen and further links to tutorials and online documentation are also provided. The complete Oralux web site with FAQs is available on the CD. Other notable features include the ability to save user preferences on a floppy disk, hard disk or USB pen drive and support for braille terminals. Besides providing visually handicapped persons with access to computers and technology, the above projects demonstrate the tremendous value of open source software and the GPL license. Thanks to these qualities, those most in need are able to modify software to better suit their own requirements and release the modifications for the benefit of those who find themselves in a similar situation. This in turn creates communities of users, developers and enthusiasts with one common goal - to create better software and, in case of BRLSPEAK and Oralux, to enhance the quality of lives of our less fortunate fellow citizens. Well done!
Distribution News Debian GNU/LinuxThe Debian Weekly News for August 19, 2003 is out. This week covers a review of LibraNet, GNU/LinEx distribution more free than Debian?, discussions on debian-legal on the definition of "software", new rescue CDs, and much more.August 16, 2003 was the tenth anniversary of the first release of the Debian distribution. Debian has come a long way; congratulations are due to the many hundreds of developers who have worked at making it better over the years. In commemoration of the event, "zwazo" has created 10 Years!, a wallpaper made with The GIMP for the 10 year anniversary of the Debian project with text from Ian Murdock's original announcement. In this lengthy Bits from the RM, Debian Release Manager Anthony Towns examines the possibility of a stable release (of Sarge) before the end of the year. To get there, the experimental branch needs to be more widely used. Also outlined is a new policy for NMUs. DebianPlanet covers a Netcraft article which says, "Debian is the second most popular Linux distribution we find on internet web sites, surpassed only by Red Hat, and leaving the likes of SuSE and Mandrake in its wake." Manoj Srivastava, Debian Project Secretary, has re-opened some pending issues. The issues are: Constitutional amendment: disambiguation of 4.1.5 and Constitutional amendment: alternate disambiguation of 4.1.5.

Page editor: Rebecca Sobol Development The Enterprise Volume Management SystemThe Enterprise Volume Management System (EVMS) is an open-source data storage system that has been developed at IBM, it has been released under the GNU General Public License, version 2.
The Enterprise Volume Management System (EVMS) Project has the goal of providing unparalleled flexibility and extensibility in managing storage. It represents a new approach to logical volume management for Linux. The architecture introduces a plug-in model that allows for easy expansion and customization of various levels of volume management.
EVMS provides a single, unified system for handling all of your storage management tasks. EVMS recognizes all of the disks on your system and allows for a variety of partitioning schemes. Software-RAID and logical volume groups can be managed in EVMS. Filesystems can be created and checked, and are automatically updated when changes are made to the underlying volumes. With EVMS, there is no longer a need for several individual utilities for performing each of these tasks.
EVMS has been designed to work with a large number of existing storage management systems on a number of different operating system platforms, it also supports all of the common Linux filesystem types. Management of EVMS can be performed with a gtk-based GUI, a curses-based terminal mode, and a command line mode. The EVMS User Guide has examples of the various interfaces, in addition to a lot of additional information. Further information on the inner workings of EVMS can be had from the EVMS 2.0 Architecture Overview and the EVMS Cluster Design Document. Version 2.1.1 of EVMS has been announced this week. It is a maintenance release that features a few bug fixes and support for the latest version of Device-Mapper. If you have a need for managing large amounts of data, EVMS is worth checking out.

XML Introducing Anobind (O'Reilly)Uche Ogbuji discusses his Python-XML binding software, Anobind. "My recent interest in Python-XML data bindings was sparked not only by discussion in the XML community of effective approaches to XML processing, but also by personal experience with large projects where data binding approaches might have been particularly suitable. These projects included processing both data and document-style XML instances, complex systems of processing rules connected to the XML format, and other characteristics requiring flexibility from a data binding system. As a result of these considerations, and of my study of existing Python-XML data binding systems, I decided to write a new data Python-XML binding, which I call Anobind."

Python & Java: a Side-by-Side ComparisonStephen Ferg compares programmer productivity between Java and Python. " A programmer can be significantly more productive in Python than in Java. How much more productive? The most widely accepted estimate is 5-10 times. On the basis of my own personal experience with the two languages, I agree with this estimate. Managers who are considering adding Python to their organization's list of approved development tools, however, cannot afford to accept such reports uncritically. They need evidence, and some understanding of why programmers are making such claims. This page is for those managers."

So the larger developer community has taken over and has done so very successfully."

The discussion includes many topics including SCO, GNU/Linux distribution choices, Digital Rights Management, dual licenses schemes, and more. "RMS: No wise person looks forward to a major battle, even if he expects to win it. Rather than being concerned that we have not yet tested the GPL in court, I'm encouraged by the fact that we have been successful for years in enforcing the GPL without needing to go to court. Many companies have looked at the odds and decided not to gamble on overturning the GPL. That's not the same as proof, but it is reassuring. "
SCO Turns Up the Heat on Linux Users (eWeek)eWeek had a conversation with SCO Group CEO Darl McBride. "'In a nutshell, this litigation is essentially about the GNU General Public License and all it stands for. That license has not yet been challenged or tested in court, but it is now going to be. We are also firmly and aggressively challenging the notion that Linux is a free operating system,' McBride said."
Resources Dispelling the Myth of Wireless Security (O'ReillyNet)Rob Flickenger, author of Wireless Hacks, circumvents security on a standard 802.11b network, on O'ReillyNet. "[Even] if all standard precautions are in place, how much "security" do wireless access points actually provide? Having heard all sorts of widely varying estimates and assumptions from people who should be able to make an educated guess, I finally decided to see for myself what it would take to circumvent the security of my own standard 802.11b network."
Winning the War on spam: Comparison of Bayesian spam filters (dataparity.no)A comparison of Bayesian spam filters by Kristian Eide is available on dataparity.no. "Fortunately, just as we seemed to be losing the war on spam, a new technique appeared on the scene after a paper by Paul Graham: Bayesian filters, our last, best hope for spam-free inboxes." Four spam filters are compared in the article.
An Introduction to perl-ldap (Linux Journal)Linux Journal has published a review of perl-ldap. "As systems get larger and the number of users they support increases, it becomes more difficult to manage systems using only the old-fashioned UNIX /etc/passwd file. A common solution to this problem is to use a Lightweight Directory Access Protocol (LDAP) server. The use of an LDAP server presents a problem to the system administrator, however, in that the contents of the database are no longer available in an easy to read or modify format. Hence, new tools must be written that allow standard, everyday tasks, such as adding or deleting users, to be performed. This is where perl-ldap comes in. perl-ldap provides the Net::LDAP perl module, which enables easy access to the data contained in LDAP directories from Perl scripts. This makes the module a useful tool for system administrators and Web developers alike."
Reviews Rapid Pace of Development for Mozilla Firebird (MozillaZine)MozillaZine looks at the rapid development pace of the Firebird browser project. "Mozilla Firebird has grown from its modest beginnings as an offshoot of the mainstream Mozilla project to become the centre of the Mozilla Foundation's future strategy. In the past, development has sometimes been tumultuous: weeks of furious activity have often been followed by periods of almost no change at all and at several points the project has come close to death. Fortunately, Firebird development has been rapid in recent weeks as the program makes the last remaining changes necessary for it to become the default Mozilla browser, which is likely to occur in the 1.6 timeframe."
An introduction to Thunderbird, part 5 (Nidelven-it)Kay Frode continues the introduction to Thunderbird series with part 5. "One of the best features about Thunderbird is the spam (junk) mail filter. Thunderbird has a built-in filter which can be adjusted and tuned in for your own pleasure. You may need to spend a week or two training it what's spam and what's not spam, but it will be worth it. :)"
Linux supercomputer rocks down under (Vnunet)Vnunet covers the Australian Computational Earth Systems Simulator (ACcESS) at the University of Queensland in Brisbane, Australia. "It is based around an SGI Altix 3000 supercomputer, powered by 208 Intel Itanium 2 processors. Built on SGI's NUMAflex non uniform memory access scalable architecture, it boasts a hefty 208GB of main memory and also uses the new Silicon Graphics Onyx4 UltimateVision graphics system."
Project searches for open-source niche (ZDNet)ZDNet covers a new open-source search engine. "Called Nutch, the project is developing open-source software for locating documents online. But unlike major search providers, it won't cloak its formulas for matching relevant results to visitors' queries. Rather, it will provide an open window into its calculations with links to explanations on how it determined each result, according to lead architect Doug Cutting."
Miscellaneous V8 racers get in-car Linux safety system (ZDNet)ZDNet Australia reports on a different Linux-based crash analysis application: video data collection in race cars. "For a trial run at Oran Park on the weekend, Opia Vision fitted each car with a camera linking back to a customised computer using Red Hat Linux. The computers measure 285 x 200 x 85 mm and use SOM (system on module) motherboards, essentially a full computer on a four-inch square board."
Page editor: Forrest Cook Announcements Non-Commercial announcements OSDL Response to SCO Lawsuit - No Reason to PayThe Open Source Development Labratory (OSDL) has released a Q&A paper on the SCO lawsuit, designed to help IT managers understand the risks of ignoring SCO's demands for Linux license fees. Here's the press release announcing the paper, in which OSDL CEO Stuart Cohen states, "we see no evidence that end users are slowing down their Linux implementation plans because of SCO's actions.. OSDL's position on this issue: .. there is real doubt as to whether end users should purchase a license from SCO." The paper, written by technology law expert Lawrence Rosen, can be found here (PDF format) and in HTML here.

"We intend to use this capital to continue our intellectual property protection and licensing initiative as well as for launching SCOx, our Web services strategy." SCO has also put out a press release on insider trading that, as far as we can tell, says almost nothing at all.
A report from SCO ForumA report from the first day at SCO Forum has been posted on the Yahoo investment boards; it is split up so you have to look separately at part 1, part 2, and part 3. It is an interesting look into what is happening there. "There was a strange disconnect between the morning sessions, putting down the GPL, and the afternoon sessions, where GPL'd software was used as a 'savior' of the OpenServer and UNIXWare products. It was mystifying to me how the participants could achieve this disconnect, but they seemed happy about the use of SAMBA 3 to achieve Active Directory compatibility and the announcements of other ports of GPL'd software from the Linux codebase to SCO products."
