LWN.net Weekly Edition for October 30, 2003
Happenings on the DMCA front
It has been a busy week for those who watch the Digital Millennium Copyright Act and its effects. Here's a quick summary of what has been happening.Every three years, the Librarian of Congress must consider applications for exemptions to the DMCA's anti-circumvention provisions. The decisions for this cycle have just been posted; they may be downloaded in PDF format. Four applications were granted this time:
- Compilations consisting of lists of Internet locations blocked
by commercially marketed filtering software applications...
Interestingly, the exemption explicitly does not extend to anti-spam
blacklists.
- Computer programs protected by dongles that prevent access due to
malfunction or damage and which are obsolete.
- Computer programs and video games distributed in formats that have
become obsolete and which require the original media or hardware as a
condition of access.
- Literary works distributed in ebook format when all existing ebook editions of the work ... contain access controls that prevent the enabling of the ebook's read-aloud function and that prevent the enabling of screen readers to render the text into a specialized format.
Many other proposals were turned down. As Ed Felten notes,
"My own exemption request, asking for exemptions for information
security researchers, was denied as expected.
" Blanket exemptions
for (otherwise) non-infringing uses, or for fair use were turned down as
not properly specifying which works should be exempted. A requested
exemption for making backup copies of DVDs went down because it did not
show, to the Librarian's satisfaction, that DVDs are fragile or that making
a backup copy is a noninfringing use.
Static Control Components has been engaged in a DMCA fight with Lexmark over printer cartridges. SCC makes toner cartridges which work in Lexmark's printers; Lexmark has made the claim that SCC's products, by circumventing a printer "feature" that causes it to not function with cartridges manufactured by others, violate the DMCA. As part of its fight, SCC asked for an exemption specific to printers that would make its products unambiguously legal. The proposed exemption was turned down because, according to the Librarian, the existing interoperability exemption covers this case. Thus, in losing its exemption, SCC appears to have won its case with Lexmark; the company lost no time in issuing a press release to that effect.
Speaking of press releases, 321 Studios, a company which sells a DVD-copying program, has announced that it will be appealing the ruling on the making of backup copies of DVDs.
Finally, there is a growing case involving numerous people - mostly college students in the U.S. - who are fighting DMCA takedown notices from Diebold Election Systems. Diebold is a manufacturer of computerized voting machines. These students came into possession of some internal Diebold correspondence which shows a distressingly cavalier attitude toward the accuracy of election votes and the integrity of the election process in general. Diebold, rather than facing up to its problems, is simply trying to suppress the incriminating memos. For those who understand the net, the results of this effort have been entirely predictable: copies of the correspondence have now been distributed worldwide. The organizers of this effort are calling for help, however, in the form of additional mirrors and publicity. This effort deserves support; transparent and accurate management of elections is too important to be pushed aside by the DMCA.
A look at Fedora Core 1
With the first stable release of the Fedora Core scheduled for early next week, we thought we'd take a look at the final test release to see what users could expect from Fedora.This release ("Severn") looks and feels like recent Red Hat releases, which is not entirely surprising. The default desktop is still GNOME with Metacity as the window manager. For the most part, if you're familiar with the Red Hat 9 release, Fedora will contain few surprises. The installation procedure is mostly the same as Red Hat 9, though users now have a few additional install options. Fedora 0.95 includes the ability to perform a graphical install via FTP, HTTP and the ability to perform an install via VNC.
We installed the Severn release on two machines to see how well it fared. On one machine we installed the "Server" package set, and performed a "Custom" install on the second machine. The entire install took less than thirty minutes on an Athlon 2600+ XP machine with 1 GB of RAM, and about forty-five minutes on an Athlon 1GHz machine with 1 GB of RAM.
The only real glitch we encountered was that Severn had a little trouble setting up the Matrox G450 dual-head video card. Though it offered the option of performing a dual-head setup that spanned both monitors, it kept producing a cloned display. A quick hand-edit of our XF86Config file solved the problem.
The firewall configuration during installation is somewhat simpler than the configuration that was present in Red Hat 9. Red Hat 9 offered "High," "Medium," and "No Firewall." The option with Fedora is to turn the firewall on or off. The user is also able to specify specific ports that should be passed through the firewall. The installer offers the options of passing through SSH, HTTP, FTP, Telnet, SMTP or specifying their own protocol that can be passed through.
Though it's a small thing, one also notices a difference in attitude during the installation. Instead of seeing Red Hat promotions during the install, the user is told that Fedora has a new graphical boot feature ("Who understood all that text scrolling by anyway?") and is encouraged to sign up for Fedora user and developer lists ("Hey! It's better than spam!").
There is a full list of packages for Severn test 3 release here. It may change slightly for the final release. Most of the packages have been updated since Red Hat 9, of course, but the package list hasn't changed that much.
One new inclusion in Fedora is Yum, an APT-like package installer/updater. Yum is not installed by default, but it is included on the Severn CDs. Yum has a command set similar to apt-get. One striking difference, however, is when using "yum check-update" to retrieve information on changed packages. The apt-get update command simply retrieves an index file for each package repository, which is fairly fast. Yum, on the other hand, retrieves RPM header information for every installed RPM, which can be very time-consuming.
Some packages have not made the cut from Red Hat 9 to Fedora. The LPRng print system is no longer supported or included with Fedora. CUPS is now the official, and only, print spooler for Red Hat/Fedora systems. According to the Fedora 0.95 release notes, LPRng will be replaced by CUPS even if the user decides to upgrade an existing Red Hat system with Fedora. Galeon is out, replaced by Epiphany. Users no longer have the option of using the LILO bootloader. Pine has been kicked due to licensing issues and "long-term maintenance concerns." Zebra has been replaced by the Quagga Routing Suite, and Tripwire has been removed as well.
Another interesting change is the inclusion of the Native POSIX Thread Library (NPTL). The Severn release ships with a 2.4.22 kernel with NPTL replacing the user-space LinuxThreads implementation. This means that some applications, notably Sun's Java Runtime Environment (JRE) prior to 1.4.1 and IBM's JRE will have issues. For applications that need the old implementation, there is a workaround described in the release notes.
The Fedora kernel also includes "exec shield," a kernel patch that we covered last May. By default exec shield is turned on for programs that are "marked" for this functionality. For the Fedora release, this pretty much means that the program needs to have been built with the Fedora toolchain.
Fedora Core 1 is still very much a Red Hat product, even if the "Red Hat Linux" name has been filed off. There has not, as yet, been time for a true development community to form; traffic on the Fedora mailing lists is tiny relative to those of, say, Debian or Mandrake's Cooker. So it is hard to guess what Fedora will look like in the future. But, if Fedora 0.95 is any indication, the first "stable" release looks to be shaping up well. If all goes as planned, Fedora Core 1.0 will be released on Monday, November 3.
SCO responds to IBM's counterclaims
The SCO Group has filed its response to IBM's counterclaims; the full text may be found in PDF format. Since this document is structured as a set of direct responses to the claims made by IBM, much of what's there must be read in the context of IBM's amended filing to make sense. SCO's responses come down to a relatively small set of points, however, which we will examine here.One area of dispute has to do with exactly what rights were bought from Novell in 1995. Novell claims the right to veto some of SCO's actions, such as the yanking of IBM's AIX license. SCO disputes that claim. Without access to the actual agreement between the two companies, it is impossible to come to any conclusion here; this will be a job for the court.
IBM's claim #16 reads:
This would seem like a relatively uncontroversial thing for IBM to say. Even SCO, in the end, has embarked on all this litigation because Linux has become "the operating system of choice" for many of its former customers. Here's SCO's response, however:
This is, of course, the company that made a go at developing and selling Linux for years, even after it obtained its rights, whatever they may be to the Unix code base.
Much of SCO's response, however, is aimed in a different direction: SCO is, once again, claiming that the GPL is not an enforceable license. Thus, for example, when IBM claims:
SCO responds with:
In other words, according to SCO, those who write code are not entitled to attach a license to it, and even if they were, the GPL is not a valid license. This anti-GPL rhetoric reaches its peak in the "affirmative defenses" at the end of the filing:
- The General Public License ("GPL") is unenforceable, void
and/or voidable, and IBM's claims based thereon or related thereto
are barred.
- The GPL is selectively enforced by the Free Software
Foundation such that the enforcement of the GPL by IBM or others is
waived, estopped, or otherwise barred as a matter of equity.
- The GPL violates the U.S. Constitution, together with copyright, antitrust, and export control laws, and IBM's claims based thereon, or related thereto, are barred.
The counterclaims offer no evidence for any of the above claims; they are simply put out there to stand on their own. The first claim will, eventually, depend on what a court finds, but many are confident that the GPL will hold up just fine. The second is ridiculous; whether or not the FSF is selective in its enforcement of the GPL has no relevance to how IBM enforces its own copyright rights. Bringing the Constitution and antitrust law into it (with the third claim) is new, but SCO's previous reasoning on the GPL and copyright law has been humorous at best.
In other details, SCO denies that its "letter to Linux users" threatened any sort of litigation. Strangely enough, SCO has removed that letter from its web site, making it harder for anybody who might want to check for themselves. Happily, this SCO v. IBM site has kept a copy handy.
SCO also goes to some lengths to try to fight off IBM's patent claims. The response even alleges that IBM might not own the patents at all.
Most of the defenses seem like a sideshow, however, compared to SCO's sustained attacks on the GPL. Clearly, the company sees the GPL as an obstacle that must be overcome. Just why SCO is so eager to see the GPL defeated is still not entirely clear, however. Perhaps the company simply wishes to destroy the Linux ecology outright so that there might yet be room for its outmoded, failing proprietary offerings. Or perhaps SCO is trying to find a way that it can apply a tax to all Linux shipments. Or maybe it is all a simply set of delay and FUD tactics while the real goal is pursued elsewhere. Given that we are facing a concerted attack on one of the pillars of the free software community - an attack now funded with another $50 million in investment money - it is proper to be concerned. Unless the attackers can come up with some better arguments, however, the GPL looks set to stand for a long time yet.

Weblog Comments - A New Frontier for Spam
The war over spam has erupted recently in a new arena: weblog comments. The parallels to the battles that have been fought on the email spam front are considerable, but unlike email spam, weblog spam is targeted at Google (and other search engines that use number of links to derive page rankings) to increase the visibility of the sites that are being advertised via spam. Comment spam seems to be on the rise with weblog owners noticing a large increase in the number of incidents over the last month or two.Weblogs are sites that allow the owner to post articles and essays of whatever happens to strike their fancy that day and most weblog software enables readers to post comments on the stories. LWN's comment system provides the same feature for this site but, unlike LWN comments, many weblogs allow (and even encourage) anonymous comments. That openness, like the lack of sender authentication for email, provides an avenue for abuse. Requiring registration before allowing comments does not eliminate the problem entirely (LWN has had a small amount of comment spam), but it does increase the amount of work the spammer must do.
The basic mode of attack uses a program to automatically post comments on multiple articles throughout the weblog. These unwanted messages include the URL of a website that will give you the opportunity to buy one or more of the usual items: diplomas, prescription drugs, porn, etc. The program then moves on to other sites using the same software, aided, no doubt, by the various directories of weblogs using a particular software package that are available. Eventually, Google and other search engines visit the weblog sites; thereafter, the spammer's site gains a high ranking due to all of the links to it that are found.
One of the more popular (though not entirely free) packages for running a weblog is Movable Type; its user community has been the most active so far in combating comment spam. For example, one set of tips (described by Yoz Grahame) attempts to thwart the way the current spam programs work by changing the default behavior of the software. Something as simple as changing the "post a comment" link can be sufficient to confuse most automated comment posting scripts. These techniques will only help until enough people implement them and it makes it worth the effort for a spammer to write more adaptable code to circumvent them.
Many of the other comment spam handling techniques will seem very familiar to anyone who has been dealing with the deluge of email spam: bayesian filtering and blacklisting based on the URLs in the comment and/or user profile are two of the more popular techniques. Bayesian filtering uses the frequency of words in a message and a database of word counts from previous messages that have been categorized as spam or non-spam (often called "ham") to determine a probability that the new message is spam. If the probability is too high, the message is rejected. The blacklisting patch collects the URLs that are advertised in the offending messages and rejects any comments that refer to any of those URLs. Both of these techniques can be worked around by a spammer with enough incentive, but it does make it much more difficult.
Another technique that is becoming more popular is email and web-based challenge-response systems which generate a blurry graphic that is (presumably) only readable by humans. Such systems require that the text in the graphic be typed into a form to ensure that a human, and not a program, is initiating the action. This technique, too, has made its way into the arsenal of webloggers via this plug-in for Movable Type. This scheme does have a number of downsides because it requires a graphical browser to post messages and may be unusable by the visually impaired.
Other weblogging software developers may have run into this problem and come up with their own sets of fixes, but the Movable Type community appears to be the at the forefront of this particular battle. Perhaps the spammers have yet to target other systems in an automated way. If (or more likely when) they do, newly targeted weblogging software can use one or more of the techniques above to combat the spam.
Both weblog comment and email spam fighters are running into the same issues and producing similar solutions in many cases and cooperation between the two groups will lead to better spam fighting. One of the future plans for Jay Allen's blacklist (above) is to create a distributed list of URLs that are being advertised via spam and with proper controls one can imagine that list being useful to the email spam fighting crowd. A filter using the rules for email message bodies in SpamAssassin might be useful for folks confronting spam in their weblog comments as well.

Interview: Brian Hatch (LinuxQuestions)
LinuxQuestions.org interviews Brian Hatch, author of Hacking Linux Exposed. "So true, not everyone can read and understand the code that they end up running, and not anyone can read all of the code that they end up running. There's a level of trust, and that's no different than when you run proprietary software. The big difference is the number of individuals who do view that code."

Kernel development
Brief items
Kernel release status
The current development kernel is 2.6.0-test9, released by Linus on October 25. It consists almost entirely of important fixes, of course, but Linus also threw in Jeff Garzik's "libata" driver. As always, the long-format changlog has the details.It seems a real 2.6.0 release could be getting close:
Linus's approach of restricting patches to the most important fixes should help to stabilize the kernel. It also is likely to mean, however, that there will be a substantial pile of patches waiting to go in after the 2.6.0 release.
2.6.0-test9 is, perhaps, unique in having its own press release, something that is not normally done for development kernels. OSDL, it seems, wants to be sure that the world knows where Linus and Andrew work these days.
Linus's BitKeeper tree, as of this writing, contains a relatively small number of fixes.
The current stable kernel is 2.4.22; Marcelo released 2.4.23-pre8 on October 22. Along with the usual fixes, this patch also includes an ACPI update, some driver updates, and a set of tmpfs fixes.
The Wonderful World of Linux 2.6
Joe Pranevich has updated the Wonderful World of Linux 2.6 to cover the -test9 release. This is likely to be the last update until the official 2.6 release. A rough list of changes to the document is also available.
Kernel development news
Mandrake Linux 9.2 and self-destructing CD-ROM drives
Upgrading to a new version of an operating system is always a bit of a mixed experience. The promise of new features, new applications, and better performance (one hopes) contends with the fear that the upgrade will break something that used to work. Even the most worried among us, however, do not normally worry about an upgrade causing hardware to self destruct. Those who have recent attempted to install Mandrake Linux 9.2 on a system containing an LG CD drive (shipped by Dell and numerous others) have gotten just that sort of surprise, however. An unpatched 9.2 system, it seems, can cause those drives to wipe out their firmware and cease to function.This problem has been the centerpiece of a small flood of complaints about the stability of the 9.2 release - over 250MB of updates have already been issued by MandrakeSoft. The simple fact of the matter, however, is that it is hard to blame MandrakeSoft for this problem.
The code which toasts LG drives was added to the Mandrake Linux kernel back in August, as part of a general packet writing support patch. It issues a standard ATAPI FLUSH_CACHE command to the drive at times, in order to ensure that all outbound data reaches its intended destination. A CD-ROM is a read-only device, so the FLUSH_CACHE command does not make any particular sense in this context. But, for the purpose of the packet-writing code, it was easier to simply issue that command unconditionally.
The ATAPI specification is clear on what should happen in this situation; the drive should either simply ignore the command, or it should fail it with an error code. The designer of the LG drive firmware, however, had a different idea. Since FLUSH_CACHE is not a command that is applicable in this situation, why not reuse it to overwrite the firmware in some (undocumented) way? It must have, in some twisted way, seemed like a good idea at the time. But standard commands should never be re-purposed in this way; and they especially should not be turned into a self-destruct operation. The LG drives are non-compliant and mis-designed, and nobody can blame MandrakeSoft for having been the first distributor to get burned by this poor product.
Some people have tried to lay the blame there anyway, of course. According to the critics, if MandrakeSoft would only test its releases more thoroughly and avoid including non-standard kernel patches, this sort of episode would not occur. These charges do not hold water, however. Mandrake Linux has, arguably, the most open development process of any commercial distributor; anybody who is interested can follow the evolution of each release from one day to the next and, yes, test those releases. The code in question was included in two 9.2 release candidates, but nobody pointed out the problem. It is hard to see how much better MandrakeSoft could do on the testing front.
With regard to patches: for better or worse, shipping patched kernels is standard practice for distributors. Some distributors ship kernels which are hard to recognize as being derived from any mainline release; Red Hat's kernels are called 2.4.x, but, at the moment, are packed with 2.6 code and features. Even Debian has just been through a lengthy (and somewhat inconclusive) debate on just how heavily its kernels should be patched. For many patches, use in distributor kernels is a prerequisite to inclusion in the mainline. The use of patched kernels in distributions is not only standard practice, but it's a part of the wider development process.
New code will bring surprises, though, hopefully, not often of this magnitude. The only real way to be sure of the stability of code is to see it in wide use, in many different situations. Unfortunately, in the software world, the only way to achieve that degree of testing is to have the end users do it. This is true for both free and proprietary software. Such is life in this industry. MandrakeSoft got unlucky this time; the next such incident could just as easily happen to anybody else.
(Mandrake users may want to see the errata page for the LG drive problem).
User-space device enumeration
Mark Bellon recently announced the first release of a tool called "User-Space Device Enumeration," or "uSDE". uSDE maintains a directory full of device nodes based on hotplug events and information found in sysfs. It is thus intended to be a user-space replacement for the devfs filesystem.Few doubt that the objectives for uSDE make sense. But quite a few developers have asked why the uSDE developers went off and created their own system, rather than working on udev (which recently released version 005). Given that the two projects appear to be trying to do exactly the same thing, it seems strange that the work is being done twice.
According to Mr. Bellon, uSDE was developed because udev wasn't up to the
needs of Carrier Grade Linux. What needs they were trying to meet are not
entirely clear; his posting is full
of language like "Aggressive device enumeration. Multiple concurrent
policy execution and management.
" In fact, the actual requirements
imposed by the CGL specification are minimal; as posted by Greg Kroah-Hartman:
Meeting this requirement with existing tools is not that hard to do.
uSDE appears to be the result of a different design approach. It uses a complicated plugin architecture to implement different device naming policies. As a whole, it is rather larger and more complex than udev. It does provide some functionality that udev is still lacking, including a devfs emulation module. In general, it shows the signs of having had more developer time put into it than udev.
But, while uSDE may be a little further developed than udev, it looks set to lose the fight for developer support and mindshare. The development of udev has followed the informal rules of kernel hacking: it has been done in the open, with feedback received along the way. It also doesn't hurt that udev is the project of a core kernel developer. uSDE, instead, has been developed in isolation, in competition to an established project, and was late to enter the public arena. Whether or not uSDE is, in fact, a better solution, the way in which it has been developed has put it at a disadvantage relative to its competition.
Driver porting
Examining a kobject hierarchy
| This article is part of the LWN Porting Drivers to 2.5 series. |
![[Kobject symbol]](https://static.lwn.net/images/ns/dp/kobject.png){kind=small}
The core data structure in this investigation is the kobject. In the
diagrams that follow, kobjects will be represented by the small symbol you
see to the right. The upper rectangle represents the kobject's parent
field, while the other two are its entries in the doubly-linked list that
implements a kset. Not all kobjects belong to a kset, so those links will
often be empty.
At the root of the block subsystem hierarchy is a subsystem called
block_subsys; it is defined in drivers/block/genhd.c. As
you'll recall from The Zen of Kobjects, a
![[Block subsystem]](https://static.lwn.net/images/ns/dp/block-subsys.png)
subsystem is a very simple structure, consisting of a semaphore and a
kset. The kset will define, in its ktype field, what type of
kobjects it will contain; for block_subsys, this field is set to
ktype_block. Pictorially, we can show this structure as seen on
the right.
Each kset contains its own kobject, and block_subsys is no exception. In this case, the kobject's parent field is explicitly set to NULL (indicated by the ground symbol in the picture). As a result, this kobject will be represented in the top level of the sysfs hierarchy; it is the kobject which lurks behind /sys/block.
![[Disk symbol]](https://static.lwn.net/images/ns/dp/disk-box.png)
A block subsystem is not very interesting without disks. In the block
hierarchy, disks are defined by a struct gendisk, which can be
found in <include/linux/genhd.h>. The gendisk interface is
described in this article. For our
purposes, we will represent a gendisk as seen on the left; note that it has
the inevitable embedded kobject inside it. A gendisk's kobject does not
have an explicit type pointer; its membership in the block_subsys
kset takes care of that. But its parent and kset
pointers both point to the kobject within block_subsys, and the
kset pointers are there too. The result, for a system with two disks,
would be a structure that looks like this:
![[Subsystem and disks]](https://static.lwn.net/images/ns/dp/disks-only.png)
Things do not end there, however; a gendisk structure is a complicated
thing. It contains, among other things, an array of partition entries (of
type struct hd_struct),
each of which has embedded within it, yes, a kobject. The parent of each
![[Partitions]](https://static.lwn.net/images/ns/dp/partitions.png)
partition is the disk which contains it. It would have been possible to
implement the list of partitions as a kset, but things weren't done that
way. Partitions are a relatively static item, and their ordering matters,
so they were done as a simple array. We depict that array as seen on the
right.
As you can see, the kobject type of a partition is ktype_part. This type implements the attributes you will see in the sysfs entries for each partition, including the starting block number and size.
![[I/O request queue]](https://static.lwn.net/images/ns/dp/iorq.png)
Another item associated with each gendisk is its I/O request queue. The
queue, too, contains a kobject (of type queue_ktype) whose parent
is the associated gendisk. The I/O scheduler ("elevator") in use with an
I/O request queue is also represented in the hierarchy. The scheduler's
kobject's type depends on which scheduler is being used; the (default)
anticipatory scheduler uses as_ktype. The resulting piece of the
puzzle looks as portrayed on the left.
The request queue and I/O scheduler information in sysfs is currently
read-only. There is no reason, however, why sysfs attributes could not be
used to change I/O scheduling parameters on the fly. The selectable I/O scheduler patch uses sysfs
attributes to change I/O schedulers completely, for example.
Putting it all together
![[The full diagram]](https://static.lwn.net/images/ns/dp/block-kobj-sm.png)
So far, we have seen a number of disconnected pieces. The full diagram can
be found on this page; it
is a bit wide to be placed inline with the text (a small, illegible
version appears to the right). Also on that page, you'll
find a corresponding diagram showing the sysfs names the correspond to each
kobject.
The data structure as described is the full implementation of the /sys/block subtree of sysfs. The full sysfs tree contains rather more than this, of course. For each gendisk which shows up under /sys/block, there will be a separate entry under /sys/devices which describes the underlying hardware. Internally, the link between the two is contained in the driverfs_dev field of the gendisk structure. In sysfs, that link is represented as a symbolic link between the two sub-trees.
Hopefully this series of pictures helps in the visualization of a portion of the sysfs tree and the device model data structure that implements it. The device model brings a great deal of apparent complexity, but, once the underlying concepts are grasped, the whole thing is approachable.

A First Look at Turbolinux 10 Desktop
Turbolinux, established in Japan in 1992 under the name of Pacific HiTech, is one of the oldest surviving Linux companies. Like many others, it started by publishing a monthly CD-ROM containing the latest Linux software, before creating its own RPM-based Linux distribution in 1996. The company moved its headquarters to the United States in 1999, but returned to Japan some two years later when it was sold to a Japanese software firm called Software Research Associates. Turbolinux is a founding member of the United Linux consortium.Turbolinux 10 Desktop is the company's first desktop-oriented release in over a year. Although the product is currently only available in Japan, Turbolinux also plans to introduce its "Basic" edition to the English-language audience next month. Those readers familiar with the distribution might be surprised at the complete change of focus in this release - instead of continuing to develop a general purpose distribution for Linux enthusiasts, Turbolinux 10 Desktop is designed for complete novices to Linux. Its target market is the average Windows user who is interested in migrating to Linux with as little pain and learning curve as possible. It attempts to compete with products such as LindowsOS, Lycoris Desktop/LX or Xandros Desktop.
The most controversial aspect of Turbolinux 10 Desktop is the fact that it is the first Linux distribution to ship with a 2.6 kernel (2.6.0-test5 development kernel, to be precise). Some might question the wisdom of this decision, which seems to have been based on the desire to increase the product's marketability, rather than on solid technical reasons. Nevertheless, Turbolinux 10 had undergone two months of beta testing prior to its release and the company promises to supply a new stable kernel as soon as it becomes available. But while there are many nice new features in the 2.6 kernel series, not everyone will be happy using it at this time. As an example, NVIDIA has yet to produce a graphics driver that would compile cleanly under it. A wiser option would have been to give users a choice between a stable and a development kernel, rather than forcing everyone to the bleeding edge.
Installing Turbolinux is one of the more pleasant aspects of the product. The distribution's "Mongoose" installer is not only extremely functional, it is also aesthetically well-designed. It is loosely modeled on Red Hat's Anaconda, except that the choice of languages is limited to English, Japanese, simplified and traditional Chinese (Korean is gone from this release), while the selection of journaled file systems include ext3, JFS, ReiserFS and XFS. Raid arrays and logical volume management can also be set up during installation. The installer is able to configure Samba-based networks automatically, so that all networked computers are immediately browseable after first boot. This, together with flawless hardware detection and configuration contributed most to the overall positive experience with the installation program.
Turbolinux 10 comes with KDE 3.1.3 (default), GNOME 2.4.0 and XFce 3.8.18 as choices of desktop environments. The menus are greatly simplified and made to resemble Windows menus wherever possible, while hiding more advanced options and more obscure packages deeply inside menu structures. Some other aspects designed to make Windows converts feel right at home include the "My Documents" folder and the My Networks-style "Windows Network" icon on the desktop. The distribution also comes with CD and floppy automount support, as well as Turbolinux-specific "Dynaplug" tool for accessing USB flash memory and IEEE-1394 removable devices. 802.11b wireless network cards and advanced power management for notebooks are also supported.
What does Turbolinux supply in terms of configuration tools? A new "Turbo Update" is a graphical utility for security, bug fix and product updates directly from a remote FTP server or local file system. Other tools include package administration, language selection, daemon configuration, window manager selection and some Turbolinux-specific hardware configuration utilities. All of them are integrated into the KDE control panel, although they can also be launched independently.
It is important to note the differences between the Turbolinux 10 Desktop edition ($143) and Desktop Basic edition ($29). In terms of value, there is little comparison as the Basic edition lacks some proprietary applications as well as an office suite. On the other hand, the more expensive edition includes Sun's Star Suite 7 (the Asian equivalent of Star Office) and Acronis Partition Manager, as well as printed documentation and 3 years of free Turbo Update service (1 year for the Basic edition). It also comes with a proprietary ATOK Japanese input method.
While all of the above sounds fairly impressive, no distribution is perfect and Turbolinux 10 is no exception. The Turbo Update service came with misconfigured defaults and, while entering the correct path to system updates fixed the problem, the new configuration did not stick between sessions. Worse, the program kept reporting available package updates even after they had been updated. All errata information is only given in Japanese, and don't expect perfect English in system dialogs either. But possibly the worst aspect of Turbolinux is lack of any online documentation as well as an absence of English language support services, such as community web sites, user forums or mailing lists. Unless the company makes an effort to create a solid English documentation and support infrastructure, the product will only be really useful to those users who can read Japanese and who need good Japanese functionality in a Linux distribution.

Debian GNU/Linux
The Debian Weekly News for October 28, 2003 is available. This issue looks at a discussion by the XPde team on the legal implications of emulating aspects of proprietary desktop environments; Andreas Steinel announced a set of pictures that he took at OpenSaar and Linux-Kongress; an upcoming SPI Board election coming up; and more.A Debian bug-squashing party is planned for Sunday November 9th 2003, in Ecublens, Switzerland. The GULL (Groupe romand des Utilisateurs de Linux et de Logiciels Libres) is organizing the effort that will be open to members and non-members.
Ian Murdock has posted this note to the
debian-devel mailing list, with a status report from Progeny. Among other
things, Progeny has ported Red Hat's Anaconda installer to Debian.
"It is our hope that a distribution-independent Anaconda and a
distribution-independent APT (plus, eventually, a distribution- independent
configuration framework) will, along with a stronger LSB, help unify
further the various Linux distributions.

Distribution reviews
Vector Linux 4.0 (PCBurn.com)
PCBurn.com has this review of Vector Linux 4.0. "Vector Linux (download edition) bills itself as a pre-configured Slackware derivative with updated packages and all the programs you'll need for a generic desktop or file server. Basing their OS's underpinnings off of Slackware allows Vector Linux to retain the old school Unix feel of Slack while loosing some of the non essential bits accumulated up over that venerable distribution's history. Think quick Slackware installation with only the essentials."
Learning to Walk: A Linux User Migrates to FreeBSD (OfB.biz)
Open for Business continues a review of FreeBSD. "It's still about freedom, but it's freedom for a reason. It's no good being free to do a million things I don't want if I can't do the one thing I do want. FreeBSD 5.0 is just a test release: Don't try this at home, kids. It was broken in many places and I wasn't getting much work done. So I accepted someone's offer to provide me with 4.8."
Libranet 2.8.1 (NeoLink)
Neolink Computers reviews Libranet 2.8.1. "One thing I noticed about Libranet is that it's not flashy at all like a SuSE or Lycoris. It's strictly a well-built Linux distro that has an extremely useful tool set at your fingertips. It's a "get down to business" distro that does exactly that -- let's the user get down to business. It eliminates all of the learning that a newbie will have to painstakingly discover through "googling", posting to and scouring message boards, and reading an endless stream of documentation."
Enterprise Linux Server Distributions (TechNewsWorld)
TechNewsWorld compares Red Hat Enterprise Linux against several flavors of UnitedLinux. "While neither SuSE UnitedLinux nor Red Hat's distribution strayed from its Linux Standards Base (a reference platform that ensures that all applications can run across Linux distributions), hardware support favored Red Hat, if only for a larger driver base and advanced hardware detection. But we found that all hardware items were discovered and configured correctly, with few mistakes made by each distribution vendor. All UnitedLinux distributions behaved identically."
Review: SUSE 9 Professional (UnixReview.com)
UnixReview has a review of the preview release of SUSE Linux 9 Professional. "Because SUSE 9 is a major version jump (from 8.2 to 9.0), I expected the release to be significantly different from its predecessor. It definitely has some improvements, but it seems like more of a point release than a major jump. SUSE 9.0 is a modest upgrade from SUSE 8.2. There are a number of improvements, but it's not the major leap that many Linux users may be used to. The additional YaST modules may be the best reason for upgrading."

Analyze Your Classes (O'ReillyNet)
Vikram Goyal introduces the Byte Code Engineering Library on O'Reilly. "Most of us never need to go beyond the basics of coding and compiling our classes. The Java Virtual Machine (JVM) is a highly efficient engine that executes our classes and for the most part, we are happy with the way it runs. However, to extend and enhance the JVM to improve runtime performance, among other things, we need to take a deeper look inside this engine and the structure of the class files that it loads and executes. The Byte Code Engineering Library (BCEL) from the Apache-Jakarta stable helps the average developers by analyzing and manipulating the structure of class files."
Eye on performance: A load of stress (IBM developerWorks)
Jack Shirazi and Kirk Pepperdine write about Java performance on IBM's developerWorks. "TheServerSide.com discussion boards are usually quite active, so we stopped there this month to see what was happening in the world of performance. Given its name, it should come as no surprise that performance discussions at TheServerSide tend to focus on J2EE systems. Of course, that's a pretty wide-ranging subject, as it encompasses almost everything in the Java platform -- even J2ME systems are often clients to J2EE systems, so you can even get an occasional question about optimizing J2ME systems."
The easy way to non-blocked sockets (IBM developerWorks)
Kenneth Ballard covers the issue of SSL blocking in Java on IBM's developerWorks. "Although SSL blocking operations -- in which the socket is blocked from access while data is being read from or written to -- provide better I/O-error notification than the non-blocking counterpart, non-blocking operations allow the calling thread to continue. In this article, the author will cover both the client and server side as he describes how to create non-blocking secure connections using the Java Secure Socket Extensions (JSSE) and the Java NIO (new I/O) library, and he will explain the traditional approach to creating a non-blocking socket, as well as an alternative (and necessary) method if you want to use JSSE with NIO."

The language issues with constant subroutines were discussed. Bugs were found, some of which were fixed ; some others were dismissed as features. Quite an usual week for the Perl 5 porters."
This week on Perl 6 (O'Reilly)
The October 19, 2003 edition of This week on Perl 6 is out with another wrap-up of Perl 6 development news.Cultured Perl: Inversion lists with Perl (IBM developerWorks)
Teodor Zlatanov explains inversion lists as applied to Unicode, on IBM's developerWorks. "So what are inversion lists? Inversion lists are best described as a condensed summary of a bit string. They are similar to a simple run-length encoding of data, though there are some differences. Let's look at an illustrative example. Suppose you want to encode the bit string "1110011." An inversion list would store a list of three numbers: 0, 3, 5. All we store is the start position of the 1s, then the start position of the 0s, then the position of 1s again, and so on until the bit string is over."
Gtk2-Perl supports Gtk+ 2.3.0 (GnomeDesktop)
GnomeDesktop.org mentions the recent efforts of the Gtk2-Perl project team. "Only a few hours after Gtk+ 2.3.0 was released, the Gtk2-Perl team has added support for the new version to the existing Gtk2-Perl libraries."

Shells
Developer's notebook (IBM developerWorks)
John Papageorge looks at some shell programming tricks from Spence Murray. "For a Linux developer, Murray believes the shell is a powerful software development tool whose utility is hard to overestimate. 'Shell scripting is an integral part of just about everything I do, whether quickly perusing and editing plain text or writing code," he says. "It's small and quick, and its short commands make moving code around a quick and painless process. As an editor, it quickly becomes second nature.'"

XML
Using Embedded XML Databases to Process Large Documents (O'Reilly)
Mark Wilcox covers embedded XML databases on O'Reilly. "However, when you are processing a large XML document (for example one that is several megabytes in size), you often have to drop out of DOM due to memory constraints, in which you probably use a SAX processor which allows you greater control over memory consumption. But you pay a price for this control. SAX programming can be quite a bit more complex if you need to do a lot of processing based on parent-children element relations. I propose as an alternative the use of an embedded XML database so that you can continue to utilize DOM for processing but without eating all of your memory."
Profilers
OProfile 0.7 released
Version 0.7 of OProfile, a code profiler, is available. "OProfile is still in alpha, but has been proven stable for many users."

Call for Open Source Voting Hardware/Software (OpenSector)
OpenSector has published a call for open source voting machines. "I am currently seeking funding to start up a non-profit 501 c3 charitable organization to provide unique hardware and software solutions for the public good. Specifically, I would like to start by building free software and open source backed voting machines with specialized authentication and verification that would allow for ease in auditing and verifying the usage of such machines by the public. I believe it is a social imperative that we provide trustworthy and open systems that are not proprietary, nor so obscure that they cannot be widely adopted."
SCO: IBM cannot enforce GPL (InfoWorld)
InfoWorld reports on SCO's response to IBM's counterclaims in Utah District Court. "'The Free Software Foundation is the only entity that can enforce the GPL so, in effect, IBM is barred from trying to enforce the GPL with SCO,' wrote Blake Stowell, a SCO spokesman, in an e-mail response to questions. SCO's filings also assert that 'the GPL violates the U.S. Constitution, together with copyright, antitrust and export control laws.'"
Suing Your Customers: A Winning Business Strategy? (Wharton)
This Wharton "Strategic Management" article requires registration, but it is a worthwhile read on the pitfalls of the "sue your customers" business strategy, as seen 100 years ago when auto manufacturers tried to use patents to keep cheap cars out of the market. The article is mostly concerned with attacks on music traders, but it could be seen as equally applicable to the SCO case. "The litigation lasted from 1903 until 1911 and along the way, the association launched hundreds of lawsuits against Ford's customers to scare them away from his showrooms for buying 'unlicensed vehicles.' Most ordinary people of Ford's era had been content to stand by and watch the automobile makers slug it out over the Selden Patent. It was just an industry cat fight. But when the big 'money men' started suing ordinary people who were just trying to buy a cheap car, public sympathy shifted against the incumbents."
Trade Shows and Conferences
Red Hat CTO says Fedora lets company 'Concentrate on the enterprise' (NewsForge)
NewsForge covers a keynote speech by Red Hat CTO Michael Tiemann at the Enterprise Linux Forum. "Fedora, said Tiemann, will provide "the stimulus and the R&D" behind many future Red Hat innovations. And while Fedora explores the leading edge of Linux, Red Hat will concentrate on producing stable, mature enterprise products -- and, obviously, on marketing those products."
Kapor: Why the old development model is history (IT Manager's Journal)
IT Manager's Journal covers Mitch Kapor's talk at the Software Development Forum. ""Open source software, like flowing water, will go everywhere it can go," said Kapor. And that's not a bad thing; it may be harder to get ultra-rich developing software, he said, but it's easier to start a software company, thanks to the rich base of existing open source projects."
Enterprise Linux Forum: Small but important event (NewsForge)
Here's a NewsForge report from Enterprise Linux Forum. "Sometimes it's not the size of the audience that matters, but the quality. It may seem wasteful to have a high-end speaker such as Ximian's Nat Friedman talking about desktop Linux advances to a room with only 30 or 40 people in it, but when half of those people are highly-placed IT executives or government agency CIOs, and many of them are taking notes and asking cogent questions, Nat is probably doing more good in a "Let's spread the Linux word" sense than he'd do in front of 200 LUG members who already run Linux all day."
The SCO Problem
SCO attacks open-source foundation (News.com)
News.com reports on SCO's attacks on the GPL - and the fact that SCO continues to ship GPL-licensed software. "SCO spokesman Blake Stowell said SCO doesn't offer indemnification, or legal protection, for use of Samba. As a hypothetical example, if Microsoft were to decide Samba violated its file system intellectual property and start suing companies that use the software, SCO would stop including Samba but wouldn't offer customers using the software legal protection, Stowell said."
Linux Adoption
Linux Is the Enterprise Operating System (eWeek)
eWeek has decided that Linux will succeed. "Amazon.com runs its shopping carts off Oracle on Linux. You want to talk mission-critical? What could be more business mission-critical? If Amazon's shopping carts stop working, not only are thousands of customers inconvenienced but the entire world knows that the biggest Internet retailer of all has had a major foul-up."

Senate Votes for Tough Limits on Spam (eWeek)
eWeek reports that the US Senate has approved the "Can Spam" bill, by a 97-0 vote. ""The odds of us defeating spam by legislation alone are extremely low, but that does not mean we should stand idly by and do nothing about it," said Sen. John McCain, R-Ariz., chairman of the Senate Commerce, Science and Transportation Committee."
Interviews
The C++ Style Sweet Spot (artima.com)
Artima.com is running part 1 of an interview with C++ creator Bjarne Stroustrup. "A lot of people see C++ as C with a few bits and pieces added. They write code with a lot of arrays and pointers. They tend to use new the way they used malloc. Basically, the abstraction level is low. Writing C-style code is one way to get into C++, but it's not using C++ really well. I think a better way of approaching C++ is to use some of the standard library facilities. For example, use a vector rather than an array."

Reviews
System recovery with Knoppix (IBM developerWorks)
IBM developerWorks looks at Knoppix as a system recovery tool. "This is the most common scenario. Something goes haywire, and boom, no boot. No problem: boot up Knoppix and find all your local partitions nicely iconicized on the KDE desktop. (Or cruise the file tree to /mnt.) Click on the correct icon, and there are all your files. But they are wisely mounted read-only. Again, no problem: right-click the desktop icon to bring up a nice menu with a "Change read/write mode" option. This mounts the filesystem on the partition as read/write. Now you can edit any file."
A Comparison of Snort Books (Linux Journal)
Linux Journal compares Intrusion Detection with Snort: Advanced IDS Techniques with Snort, Apache, MySQL, PHP, and ACID by Rafeed Ur Rehman and Intrusion Detection with Snort by Jack Koziol. "One indication that an idea's time has come is when two publications on the topic arrive at the same time. Based on the two titles reviewed here, it's apparent that Snort is going mainstream. These two books plus Snort 2.0 Intrusion Detection and Snort: The Complete Guide to Intrusion Detection all have been released this year."
Looking into Zend Studio 3.0 (O'ReillyNet)
John Coggeshall reviews Zend Studio 3.0 on O'ReillyNet. "I've been a PHP developer for a long time, using many different development environments in my PHP projects. When I was asked to do a review of the new Zend Studio, I decided that the best way to really judge it was to actually use it in my day-to-day development. So for a week, I set aside my trusted ActiveState Komodo 2.5 and sat down with Zend Studio 3.0. Here is what I found, what I liked, and how it compared to what I was expecting."
Miscellaneous
IBM should take care of software risks (ZDNet)
ZDNet is running an impressive piece of indemnification FUD from Forrester Research. "IBM is giving its customers the blues by asking them to assume financial and legal risk with its open-source software--that's after those same customers have already shelled out hundreds of thousands of dollars for the code."
A Web of Rules (O'Reilly)
Kendall Grant Clark predicts the development process of the Semantic Web on O'Reilly. "My view, sustained by an admittedly simplistic analogy to the way the Web itself developed, is that if the Semantic Web is to happen, it will be because of a loosely coupled collaboration between three communities: the academics, the industrialists, and the hackers. This view gives me some pain, however, since the hacker community (by which I mean people who develop open source software for fun and for profit) is perhaps the one least engaged in the Semantic Web effort."
If I could re-write Linux (NewsForge)
In this NewsForge article the author speculates on building a next-generation operating system aimed at 64-bit hardware. "Linux is a pure 32-bit operating system written from scratch for 32-bit processors. It doesn't suffer from any 16-bit baggage code. Now Linux is being ported to various 64-bit processors. It will be a while before all the code is compiled and optimised to take advantage of 64-bit platforms."

Letters to the editor
Stop making products for Linux
| From: | bryanh-AT-giraffe-data.com (Bryan Henderson) | |
| To: | letters-AT-lwn.net | |
| Subject: | Stop making products for Linux | |
| Date: | Sat, 25 Oct 2003 20:19:45 +0000 |
I've just been through the exercise of buying hardware, trying to be sure I will be able to use whatever I select with my Linux system. And I have a message for the computer industry. I'm tired of companies making products for Linux. I don't want to see hardware that comes with a Linux device driver. I don't want to see a Linux version of a software package. I don't want technical support for Linux users. All this makes sense for Windows, but is contrary to the concept of Linux. What we Linux users want is products with robust and published interfaces, preferably conforming to some public standard. We want technical support at the level of those interfaces (so I can call and say, "I issued a F2 command and got back D1 status, and the spec says it should be D3"). We appreciate sample driver code, but that's just gravy. If we had that, we'd write our own drivers, test our own configurations, and package our own software. We'd even provide technical support among ourselves for the higher-level Linux users. I bought a UPS that advertised "works with Linux." Turns out that means you can download a binary RPM for Red Hat Linux 6.0 and control the product with a Windows-style GUI interface. I don't have Red Hat 6.0 or anything like it, and if I wanted to control the UPS windows-style, I'd hook it up to my Windows system. Sometimes, "works with Linux" means that the product was tested and found to work on some Linux system. But unlike Windows systems, Linux systems are, by design, not all alike. I believe the only way to truthfully claim "works with Linux" is to provide and support an OS-agnostic interface. I understand the kind of product I'm talking about is not cost-effective. That's why Windows is what it is. I'm just saying that when a product "supports" Linux in the same way it "supports" Windows, the company is just wasting its time and insulting the Linux community. -- Bryan Henderson Phone 408-621-2000 San Jose, California
