Getting Started Listening to Podcasts

July 6, 2005

This article was contributed by Dan York

Last week, I discussed creating podcasts and offered some pointers to how you could get started along with reviews of a couple of books that can help. This week I want to back up a bit and talk about how you can get started listening to podcasts.

The Basics

First, though, I do need to address the question of what makes a podcast different from a regular audio file posted on a website. On a purely technical level, nothing is really different about the audio file. In fact, if you just want to listen to a podcast to see if it is something you would like to listen to on a regular basis, the best bet is often to go to the podcast website and simply download a recent episode and play it in your media player.

What is different is the way in which the audio file is normally retrieved. Rather than being something you click on, download, and play, you subscribe to the podcast RSS feed. This works by virtue of the fact that Dave Winer added an element called an Enclosure to RSS 2.0. Note that the enclosure element is actually not specific to audio: it can be used for pretty much any media element including video or images.

The beauty of this solution is that you simply need to subscribe to whichever podcasts interest you and then listen to them whenever new shows arrive - and whenever you feel like playing them. No need to check web sites for updates. No need to be online to listen to a streaming feed. Many people have referred to podcasting as "TiVo for audio" or "timeshifting radio" and indeed it very much works that way.

So in order to subscribe to podcasts, you need some software tool that can: a) handle RSS feeds; and b) interpret the RSS enclosure tag to download the media automatically for you. At a base level, that is pretty much all you need and the software that does this is often called either a "podcatcher" or "podcast aggregator". Of course, the programs out there don't simply do the base. They add the ability to easily manage your subscriptions, schedule the interval to check (ex. setup an appropriate cron job), manage the downloaded files, etc.

The Software

Linux users have the choice, of course, of podcatcher software in pretty much any language and with or without a GUI. A search on "podcast" at sites such as SourceForge or freshmeat will turn up a variety of choices in various states of development. Some of the prime contenders are:

iPodder - For someone just getting started who wants a GUI, my personal recommendation would be to start out with iPodder (also called the "iPodder Lemon" because of its logo). Being python-based, iPodder is cross-platform and is heavily-used within the Windows and Mac worlds. Linux users receive the benefit of all that usage/testing and have a robust program to use. Screenshots are available if you would like to see what it is all about.

BashPodder - For the text-inclined, BashPodder provides the functionality you need via a basic shell script. Simple, easy, and a breeze to extend. In fact, the site contains a wide range of user-contributed extensions and customizations. Additionally, for those who want the power of the shell but still with a GUI, there is BPConf that allows you to easily configure BashPodder.

jpodder - Another interesting choice is jpodder, a Java-based cross-platform podcatcher. Like iPodder, it is GUI-based and has a range of features.

Other choices - There are a range of other options (and readers are encouraged to leave their recommendations as comments), including:

A reader last week also commented that they were able to have Apple's iTunes program running on their Linux system using CrossOver Office. In any event, you need to have one of these programs installed to have the simplicity of subscribing to podcasts.

The Next Step

Once you have the software installed, you need to find podcasts to which you can subscribe. Some of the podcatchers, such as iPodder, include a built-in directory. Even with such a directory, though, you'll probably want to check out some of the directory sites. More keep appearing on a daily basis, but some of the major sites include:

Typically all you need to do is find the URL for the show's RSS feed and then enter it into your podcatcher software. Some programs allow drag-and-drop... but in any event that's it... you are now subscribed and will start to receive new shows. (Some podcatcher software will download the most recent show and then all new shows - some software will download all shows available in the feed.)

Happy listening! And please do feel free to leave comments to this article about your favorite podcasts - or feedback about various podcatcher software.

A look at the Bizgres Project

July 6, 2005

This article was contributed by Joe 'Zonker' Brockmeier.

There are a lot of PostgreSQL-derivative projects in the news lately. In May we looked at the EnterpriseDB project. The Bizgres Project released their 0.6 release last week, with a few new features of interest to organizations using PostgreSQL for data warehousing and business intelligence.

The Bizgres project was launched in April of this year. It is based on the PostgreSQL project, with development sponsored by Greenplum, which also uses the Bizgres source code in its DeepGreen offering. Josh Berkus, who works for Greenplum and is a member of the PostgreSQL core team, talked to us about the Bizgres release and the plans for the project.

The 0.6 release has two features of interest that are not currently found in PostgreSQL. The first is a patch that speeds up bulk loading of text data. Berkus said that the patch "speeds up bulk loading of text data by refactoring some of the bulk loader code".

The other feature is an improvement in temporary table creation. When tables are created using the "CREATE TABLE AS SELECT" statement, transaction logging is bypassed which can provide major benefits in performance -- in effect, a kind of "scratch" table that can be used to hold a copy of data that is being worked with without logging transactions. Berkus said that the Bizgres team is planning on expanding the capability to include the ability to bulk load into a "scratch table" but the current feature does not allow that.

With so many PostgreSQL-derived projects available, some may wonder if the project is forking. He said that Greenplum plans to contribute its features back to the PostgreSQL project, but that the timing of PostgreSQL releases made it hard to get the features that interest Greenplum and its customers into mainstream PostgreSQL in a timely fashion:

Feature freeze for 8.1 was July 1st, that was the last day for consideration of patches for 8.1, and for that matter, if you introduced a major patch on July 1 that hadn't been discussed, there's very little chance it'd be introduced [in the 8.1 release of PostgreSQL]. Much of the stuff [in Bizgres] has bad timing, and would have waited for 8.2.

Since PostgreSQL 8.2 is currently slated for summer of 2006, there is a distinct advantage in creating a derivative distribution of PostgreSQL to allow Greenplum and the Bizgres Project to push its features out to its users earlier. Berkus compared this to Linux vendors like Red Hat backporting features from the 2.5/2.6 kernel series to the 2.4 series while 2.6 was still in development. He also compared Bizgres to embedded Linux or Real Time Linux, "in that we're focusing on a distribution of PostgreSQL entirely focused on needs of people running data warehouses or doing business intelligence". Users outside those profiles, said Berkus, probably don't want to consider Bizgres or DeepGreen at all.

He also said that the Bizgres project is focused only on Linux, Solaris and Windows, as opposed to all of the platforms that are supported by the PostgreSQL project, which produces fewer platform compatibility issues for Bizgres.

Berkus allowed for the possibility that Bizgres could have features that do not make it into mainstream PostgreSQL, if they were of benefit to data warehouse applications without providing a benefit to general performance, but that he wasn't aware of any features under consideration that would fit that category.

As for licensing, Berkus said that anything developed by Greenplum for Bizgres would be available under a "BSD or analogous license".

We want to permit commercialization. Our goal, overall is to make it the standard in data warehousing and the BSD license is the best to choose. It eliminates any legal concerns that someone might have about adopting your software.

He also said that he wasn't concerned about other companies snapping up Bizgres' technology. According to Berkus, the major vendors like Microsoft, IBM and Oracle, "already have technology of their own that they have investment in, and they're unlikely to abandon theirs... and if they did [take Bizgres features and make them proprietary] it would be enough of a moral victory that it would be worth it".

Given the number of companies working on PostgreSQL distributions, it should be interesting to see how many of the improvements flow back into the main project, and whether the various companies can avoid straying too far from the main project. It should also be interesting to see whether the Bizgres project gains much steam as an independent project. The mailing list traffic isn't particularly heavy yet, but the project is still very new.

For users who are interested in trying out Bizgres, the 0.6 release is available as source code or binaries for Solaris 10 or Red Hat Linux.

First Look at Knoppix 4.0

July 6, 2005

This article was contributed by Ladislav Bodnar

The much awaited "maxi" DVD edition of Knoppix 4.0 was presented at the Linux Tag conference in Karlsruhe, Germany last week. As usual, this was a special edition and not a public release, but it didn't take long before the ISO image hit some of the popular BitTorrent download sites and it was even spotted on a few FTP servers a few days later. The reason for the high demand is not hard to understand - Knoppix 4.0 is the largest live Linux DVD ever produced, with a great collection of "the best open source software" available today.

First, some numbers. The size of the single-layer compressed DVD image is 4,122 MB. It contains over 9 GB of software in the form of 2,663 Debian packages providing more than 5,300 individual programs. Most of them come from the recently released Debian 3.1 "sarge", but there are several noteworthy upgrades, such as KDE 3.4.1. KDE is still the default desktop, but Knoppix 4.0 now contains ten other desktop environments and window managers, including the complete GNOME (2.8.1) and XFce (3.8.16 and 4.0.6), and even some exotic ones, such as LarsWM, Openbox, and RatPoison. Booting this DVD on a 4-year old 1.4 GHz Pentium 4 system with 384 MB of RAM took just under 8 minutes (from the GRUB boot prompt to KDE); for comparison, booting the Knoppix 3.9 CD on the same system took only about 3.5 minutes.

It needs to be mentioned that, starting from version 4.0, Knoppix will be split into two editions - "maxi" DVD and "light" CD. The light edition will essentially be the same Knoppix live CD that we have come to love and appreciate over the last couple of years, except that all development software will be removed and replaced with more general desktop applications. The public release of Knoppix 4.0 is expected within the next few weeks, with the "maxi" DVD and "light" CD editions appearing simultaneously.

The Knoppix 4.0 DVD contains many of the most popular open source software packages for the desktop, server, office, graphics, multimedia, and development. Compared to the live CD edition, users now have a choice of KOffice (1.3.5) and GNOME Office (AbiWord + Gnumeric), in addition to OpenOffice.org (a recent beta of the 2.0 series). On the server side of things, both Apache 1.3 and 2.0 are present, and, unlike the CD edition, the DVD also includes PostgreSQL 8. Some other interesting packages that have been missing from all recent Knoppix CD releases include Blender, Eclipse, GnuCash, Mozilla, LyX and teTeX. One downside of the DVD is that, with so many applications included, the standard Debian menus tend to be badly cluttered and poorly organized; as an example, the "Internet" submenu contains a total of 76 items, while the "System" submenu contains 88 items!

Besides adding new packages, what else is new in Knoppix 4.0? In the absence of any changelog we had to dig around the menus and file system to see what exciting things are hiding under the bonnet. The DVD has retained the Unionfs file system so extra packages can be installed on the fly - either from Debian repositories with apt-get or the newly included Synaptic, or via the web-based Klik installer, which also includes some non-free packages. A new feature is the ability to switch between the 11 desktop environments through a "Restart KNOPPIX Desktop" utility. Also, the DVD now contains a lot more documentation in HTML and PDF formats, including the excellent 133-page Knowing Knoppix and m23 Software Distribution guides.

There seems to be an increasing level of collaboration between the developers of Knoppix and other Knoppix-derived live CD and DVD projects. The Kanotix developers contributed some DSL network configuration and hard disk installation code (due to data decompression, a partition of at least 12 GB in size is required for installing the DVD edition of Knoppix 4.0 on the hard disk). Much of the newly included scientific and statistical software was accepted from the Quantian and Paipix live DVD projects, while a lot of educational software found its way into Knoppix from Freeduc, a distribution designed for schools.

Although providing a large number of applications on the DVD should please those users who missed some important pieces of software on the earlier CD editions, the size of the DVD presents its own set of problems. We have already mentioned the unsightly and difficult-to-navigate menus, but a potentially more annoying problem is the general sluggishness of the system while it runs from the DVD. Maybe a more modern DVD drive would be able to launch software packages in a speedier manner, but we were not impressed with a delay lasting several minutes after clicking on a PDF file in Konqueror. Likewise, OpenOffice.org Writer took 150 seconds to launch. Even navigating the menus was painfully slow, much slower than any of the CD editions. Of course, once an application is cached in the memory it starts a lot faster, but the first run of any large software package will likely test your patience.

This brings in the question about how useful a 4 GB Knoppix live DVD really is. Although it is easy to get excited over all the goodies available at a mouse click, many people will undoubtedly be put off by the long boot times, poor system responsiveness and cluttered menus. After having played with the system for a few minutes, we found ourselves craving for the much leaner and faster Knoppix CD - although not nearly as full-featured as the DVD edition, it contains enough applications to satisfy the majority of users. Whether you use Knoppix as a rescue CD, carry it around to boot computers in Internet cafes, or employ it to demonstrate Linux and open source software to interested parties, the CD edition of Knoppix will probably remain a more practical tool than the more complete, but also more sluggish DVD edition.

PEAR XML_RPC remote code execution vulnerability

July 6, 2005

This article was contributed by Joe 'Zonker' Brockmeier.

A serious vulnerability in the PEAR XML_RPC library and the XML-RPC for PHP package has been disclosed. The vulnerability allows unsanitized data to be passed to the eval() call, which would allow execution of arbitrary PHP code.

The vulnerability was reported by James Bercegay of the GulfTech Security Research Team. Bercegay reports that the parseRequest() function passes data to eval() without sanitizing the input first. As a result, a properly-crafted XML file can be used to execute PHP code on the targeted server. Bercegay's advisory gives an example that could be used to execute the relatively harmless phpinfo() function to be executed on a target server: 

<?xml version="1.0"?>
<methodCall>
<methodName>test.method</methodName>
  <params>
    <param>
      <value><name>','')); phpinfo(); exit;/*</name></value>
    </param>
  </params>
</methodCall>

PEAR's library or the XML-RPC for PHP package are used in a number of PHP-based projects, including WordPress, Drupal, PostNuke, Xaraya, phpGroupWare, Tikiwiki, and many others, which means that there are a lot of vulnerable servers out there. Users of PHP-based blogging applications and other packages that use XML_RPC should check to see if the software is vulnerable and update the package as soon as a new release is available. Some projects, like PostNuke, are advising users to remove the offending code altogether.

PEAR's XML_RPC library is also distributed with many Linux distributions. Most of the vulnerable projects and distributions have announced updated packages, and the PHP project has bundled the new PEAR XML_RPC package in PHP 4.4.0RC2, and a separate release is available on the PEAR site. The final PHP 4.4.0 release is scheduled for July 11. Users can also update the PEAR library by running "pear upgrade XML_RPC" as root or using sudo. An update of XML-RPC for PHP is also available.

Users should upgrade or take steps to remove the library as soon as possible, as it seems likely that exploits of this vulnerability will begin appearing in the wild soon, if they have not already.

Kernel release status

The 2.6.13-rc1 kernel was released on Jun 28. It contained over 2000 different patches, showing that there was a lot of pent-up development during the end of the 2.6.12 release cycle. It contains changes in almost all areas of the kernel, such as: USB, SCSI, driver core, ALSA, static cleanups, IDE, network drivers, network core, audit, input, pcmcia, I2C, W1, V4L, NFS, IB and ARM arch. It also contains some new features such as kexec/kdump, execute-in-place and a new architecture called xtensa. Also, devfs has been disabled from the build (but the code is still present). In all, over 3000 files were changed, with over 190000 lines added and over 84000 lines removed.

Since then, the 2.6.13-rc2 kernel was released on July 5. It had a much more manageable set of around 180 patches. The patches were mostly bug fixes for various things that were merged in the 2.6.13-rc1 release: driver core, PCI, ARM, TCP, pcmcia and serial, along with a few new options: driver binding and unbinding from userspace through sysfs.

The current stable 2.6 kernel is 2.6.12.2, it was released on July 1.

Linux 2.4.32-pre1 was released on July 4, it contains x86_64 security updates and other fixes.

Kernel development news

A couple of graphical git front ends

The development of git is a classic free software success story, even at this early stage. When Linus Torvalds needed a new tool for managing source code revisions, he sat down for a week and bashed out something which was enough for other people to play with. It didn't do much, but it contained enough in the way of good ideas and functionality that a group of developers quickly gathered around it and started making it better. Git may still have a number of rough edges, but, to a great extent, it has taken BitKeeper's place in the development process.

One of those rough edges has been the lack of graphical tools for working with the repository. Things are happening in this area as well, however, and there are now two tools available which warrant a look. These tools (being gitk and qgit) both function as patch browsers; neither, currently, can actually make any changes to a git repository. In other words, capabilities like three-way patch conflict resolution are still missing. But you have to start somewhere; either of these tools will be helpful for anybody who wishes to look at the path the kernel took to get to the current point.

gitk is a Tk-based utility written by Paul Mackerras; the current release is version 1.1. The build [gitk screenshot] process for gitk is about the easiest your editor has ever encountered; since it is written in Tcl, installation is simply a matter of putting the gitk script somewhere in your path.

Running gitk yields a three-paned window. At the top is a reverse-time list of committed patches, along with a graphical trace showing which tree each patch was merged from. Tags in the repository are indicated by a cute little yellow tag in this pane. The bottom left shows the selected patch in a fairly gaudy, colorful form. The commit text and the patch itself are run together, just as they would appear in an emailed patch. On the lower right is a list of files touched by the current patch; clicking on the name of a file narrows the view to the corresponding portion of the patch.

There is a simple "find" function which can search for patches whose description or author information match a given string; searching with regular expressions is possible. If you know the SHA tag for a given commit, you can type (or paste, presumably) it into a blank and view the corresponding patch. gitk also stores the SHA ID of the current commit in the X selection, allowing it to be pasted into git commands if need be.

The alternative to gitk is qgit, a Qt-based application currently at version 0.6. The initial experience with qgit is a little rougher; the application uses SCons for building instead of make. Since most systems tend not to have SCons [qgit screenshot] installed, the qgit tarball includes a prebuilt version of SCons and a script to hack up the build file to use it. One thinks that, for a relatively simple application, it might have been easier to just toss in a makefile.

The initial qgit window looks very similar to gitk. The lower left pane shows only the commit text, however; the actual patch is nowhere to be seen. A single click on the filenames on the right appears to do nothing; a double click will pop up a separate window with the full text of the file. It turns out that one has to double-click on the appropriate line in the top pane to get a separate window with the patch itself. Once the window is up, it will be updated with the body of any patch selected in the main window. The presentation of the patches is a bit nicer than in gitk; the use of color is a bit more restrained, and patches are shown in the diff -up format that developers are used to reading. The patch window, however, has the obnoxious feature that it is permanently on top of any other window on the screen, regardless of the user's desires.

Nicely, in version 0.6, the qgit file browser window includes line-by-line annotation which makes it easy to figure out which commit modified a specific piece of code. This feature is enough to make one wish that the kernel.org git repository contained more than a few months of history.

qgit also makes it possible to search for specific patches; entering a string in the blank and clicking "filter" will narrow the patch view to the patches containing the string. It is not obvious, but the way back to the full listing is to hit "filter" again.

Once upon a time, your editor asked the BitKeeper folks how to determine which tree was the source of any particular changeset in the mainline. The answer that came back was that this information was not available - BitKeeper did not store it. So it is pleasing to see this information so readily in evidence in either git front end. We really do have a better handle on the development history than we did even a few months ago.

Both tools can be a bit rough to use at times, and their features are limited. When one considers that, back at the beginning of March, none of this software existed at all, it is hard not to be impressed. There is a lot happening around git, and, chances are, we've just barely seen the beginning of it.

Looking at inotify again

July 6, 2005

This article was contributed by Greg Kroah-Hartman.

In September, 2004, LWN.net took a look at the inotify patch. This patch has been reworked a number of times by its primary developers, and has been living in the -mm kernel tree for a few months. With the recent What to merge for 2.6.13? discussion, inotify was mentioned as something that might be considered for merging into the main kernel tree. One thing that few kernel developers had paid attention to in the inotify patch was the userspace interface to the feature. So, let's take a look at how a programmer is supposed to interact with inotify.

From the documentation included in the kernel patch, inotify communicates to userspace through a character device, /dev/inotify. This is a misc character device (it uses the misc_register() kernel interface to create its character device), and if you use udev to manage /dev, the device node is automatically created. If not, the character node needs to be created by hand: 

	mknod /dev/inotify c 10 63
Inotify works with something called "watches". A "watch" is an object and a mask that describe an event that the user wants to receive notification events from. The object is either a file or a directory, as represented by an open file descriptor, and the mask is a bitmask of events. The different types of events that can be monitored are: 
	IN_ACCESS		The file was accessed
	IN_MODIFY		The file was modified
	IN_ATTRIB		The metadata changed
	IN_CLOSE_WRITE		The writtable file was closed
	IN_CLOSE_NOWRITE	The unwrittable file closed
	IN_OPEN			The file was opened
	IN_MOVED_FROM		The file was moved from location X
	IN_MOVED_TO		The file was moved to location Y
	IN_CREATE		A subfile was created
	IN_DELETE		A subfile was deleted
	IN_DELETE_SELF		self was deleted
If the user wants to monitor all events, a handy IN_ALL_EVENTS macro is defined which includes all of the above event flags combined together. To create a watch and register it with the kernel, an ioctl is called on the /dev/inotify node: 

	struct inotify_request request = { fd, mask };
	int watch_desc = ioctl(dev_fd, INOTIFY_WATCH, &request);
where fd is the open file descriptor of the file or directory you wish to watch, and mask is the type of event to monitor. To remove a watch that is already in place, another ioctl should be sent: 

	ioctl(dev_fd, INOTIFY_IGNORE, watch_desc);

Once a watch has been registered with the kernel, a simple read() call to the device node is used to retrieve events based on that watch (and all other watches that have been registered for this process.) The structure of the data that read from the kernel is described in the following C struct: 


struct inotify_event {
	__s32	wd;		/* watch descriptor */
	__u32	mask;		/* watch mask */
	__u32	cookie;		/* cookie to synchronize two events */
	__u32	len;		/* length (including nulls) of name */
	char	name[0];	/* stub for possible name */
};
All of the fields are pretty self explanatory, with the exception of "cookie". If this field is not set to 0, then it is used to tell userspace that multiple events happened at the same time on the same object. An example of this is renaming a file. If a directory is being watched and the following file rename happens in it: 

	mv foo baz
there would be 2 events generated, an IN_MOVE_FROM and an IN_MOVE_TO event. They would both have the same cookie value, which allows userspace to coordinate the events. The /dev/inotify node allows select() and poll() to be called on it, so a blocking read() is not necessary, which would tie up a program's thread.

The FIONREAD ioctl is also supported by inotify, and returns the size of the current pending event queue, if userspace wishes to do dynamic buffer allocation to place the events into. When the userspace program that had the /dev/inotify node open exits, or when the node is closed, all watches that were registered with the kernel are destroyed and cleaned up properly.

For a very simple example program that shows how to register for events, and read events as they happen, see the inotify-utils package that can be found here.

For more details on the kernel design decisions that the inotify developers went through in creating this system, please see the inotify documentation in the kernel patch. It describes why a character node was used instead of signals, and other details.

Yellow Dog Linux 4.0.1 and Y-HPC

July 6, 2005

This article was contributed by Ryan Paul

A conspicuous banner at the Terra Soft Solutions web site informs viewers that "PowerPC is not dead". This resonant affirmation of PPC's capacity to endure is meant to address the concerns of consumers that doubt the value PowerPC software in the wake of Apple's stunning x86 about-face.

Those that follow the issue know that the perpetuation of the PowerPC architecture is not really in dispute. With robust POWER processors in all the next generation gaming systems, it is likely that the architecture will be around for years to come. While we will soon see PowerPC consoles on top of our televisions, Apple's migration to x86 creates some questions about the relevance of PowerPC on the desktop.

With POWER supercomputers topping the list and IBM aggressively promoting Linux on POWER, it looks like the Linux PPC server market is starting to heat up. Kai Staats, CEO of Terra Soft Solutions (TSS) and a familiar face in the PPC Linux community believes that there is more than enough demand for PPC server solutions to keep him in business despite Apple's hasty retreat from the market.

TSS is an Apple reseller, best known for Yellow Dog Linux (YDL), it's popular GNU/Linux distribution for the PowerPC platform. Based on Fedora, YDL 4.0.1 is a flexible and intuitive distribution that supports a wide variety of hardware from Apple and IBM.

While broader package selection and community driven development models make non-commercial alternatives like Debian and Gentoo a superior choice for many developers and home consumers, availability of quality services and support as well as pre-installation make YDL a popular pick for schools, government agencies and corporations that utilize PowerPC technology.

The 4.0.1 release features a number of important updates and adds support for the iMac G5 and the Mac mini. I put it to the test to see how it compares to some of my favorite non-commercial distributions. Aside from the excellent hardware support and virtually flawless automated configuration, YDL is relatively unremarkable. Those who are comfortable with Fedora and RPM package management will feel right at home with it. It performs relatively well and it is relatively stable.

The limited availability of YDL RPMs is probably the most prodigious defect. While four CDs may seem like a lot, there are a lot of holes. Firefox is only available via the 'Extras' repository, and libglade for Ruby (which I use heavily for rapid application development) doesn't appear to be available at all. Developers who don't use mainstream languages are out of luck: YDL doesn't come with compilers for Eiffel, C#, Ocaml or Haskell. If you want to use GHC or Mono, for instance, you are probably better of with Debian or Gentoo. While my esoteric development needs may not be indicative of general user needs, it is likely that the needs of most users will not be adequately met by what is available within the limited YDL package ecosystem.You can use TSS's web-based repository interface to find out if YDL has the packages you need.

The boxed set comes with four installation CDs, four source CDs, a 10 page installation quickstart, a cute frisbee-esque thing bearing the YDL logo, and a comprehensive 180 page guide that contains a thorough introduction to KDE, a relatively effective introduction to the command line, and a concise introduction to Linux administration. The guide contains expository comparisons to OS X and Windows that will help users of other operating systems understand the significance of various KDE/Linux features. The most notable deficiency of the user guide is the severe KDE bias and the absence of Gnome documentation. Aside from that, the guide provides good coverage of relevant features.

The distribution comes with YUM for package management. Though YUM has become a standard part of the RedHat Linux distribution, it was originally designed by TSS (and then modified by Duke University) specifically for YDL. YUM has a smaller code base than apt4rpm and features superior dependency handling.

YDL 4.0.1 comes with a few intriguing PowerPC extras, including Mac-On-Linux (MOL), which allows users to run an entire mac environment at near-native speed inside of a window. I was looking forward to trying out MOL with OS X. Unfortunately, MOL doesn't support OS X 10.4, so I was unable to see it in action. Apparently, it doesn't support macs with G5 processors either. It's still worth looking at, and probably quite impressive when it works. Check out this spooky screenshot from the MOL web site. With any luck, MOL support for Tiger will be added soon.

TSS provides a number of services for customers. YDL.net Enhanced members get a pop/imap accessible e-mail account, early access to YDL ISOs and web hosting. Updates appear to be free via YUM.

Also of interest is Terra Soft's Y-HPC, a 64-bit PowerPC GNU/Linux distribution and "cluster construction-management suite" compatible with a wide variety of PowerPC systems, including Apple's Xserve and IBM's JS20. Y-HPC provides users with a complete 64-bit development environment that features IBM's XLF and XLC compilers. Y-HPC natively supports double-precision as well as up to 16GB of RAM and contains complete 32 and 64-bit development tool chains.

Y-HPC comes with a PowerPC port of SystemImager and TSS's unique, user-friendly image management interface called Y-Imager that facilitates visual, node-based cluster construction. Y-HPC also features PPC-64 builds of many popular open source applications.

I still prefer Debian on my desktop, but YDL presents a few compelling benefits, particularly for those who already have extensive experience with RedHat or Fedora. There are also definitely contexts in which Terra Soft's high performance computing solutions are optimal. TSS designed a YDL-based Xserve imaging cluster for deployment on US Navy submarines and provided Boeing with specialized G5 computers for Weapons Systems Officers training programs. Despite the imminent extinction of Apple PPC hardware, we may see renewed interest in TSS as demand for Linux on POWER escalates.

Track eBay bids with JBidwatcher

The JBidWatcher project is:

A Java-based application allowing you to monitor auctions you're not part of, submit bids, snipe (bid at the last moment), and otherwise track your auction-site experience. It includes adult-auction management, MANY currencies (yen, pound, dollar (US, Canada, Australian, and New Taiwanese), Swiss Francs, and euro, presently), drag-and-drop of auction URLs, a unique and powerful 'multisniping' feature, a relatively nice UI, and is known to work cleanly under Linux, Windows, Solaris, and MacOSX from the same binary.

[jbidwatcher] The project has been around since 2002, the project news shows an interesting history that involves tracking breakages caused by frequent eBay site changes.

The feature list includes:

  • General design for future compatibility with sites other than eBay.
  • Multisniping support cancels other bids after one bid has been won.
  • Designed and developed in a cross-platform environment.
  • Support for launching a web browser directly to an item that is being bid on.
  • A built-in search mechanism.
  • Support for user-customizable tabs.
  • Support for multiple languages and currencies.

Newly added features include:

  • User customizable column displays.
  • A Buy It Now feature for purchasing at a fixed price.
  • The ability to subtract shipping prices from snipe purchases.
  • An RSS feed for watching bids.
The screenshots show the user interface of an older version of JBidWatcher.

Version 0.9.7 of JBidWatcher was released this week. "This version is a major overhaul, with several major new features and dozens of bugfixes. The top four features are Customizable Columns, Buy It Now support, automatically Subtract Shipping from Snipes, and RSS Feeds." See the changelog file for more information on this release.

JBidWatcher has been released under the Lesser General Public License (LGPL). The software is available for download here.

If you are a frequent eBay auction bidder, JBidWatcher is a handy tool that can give you an advantage over other bidders. All that you need to worry about is where to store all of that new stuff you just bought.

Debuggers

An introduction to Delta Debugging (NewsForge)

NewsForge examines the Delta Debugging technique. "Every developer knows that debugging -- the process of finding and fixing defects in program code -- is an important process. Often, the effort devoted to it outweighs the cost of all the other software development phases. Debugging is unpredictable, since a single bug can hold clueless developers hostage for long time. And unfortunately, debugging has always been a mostly manual affair -- but that's about to change, with the advent of Delta Debugging."

ESR: 'We Don't Need the GPL Anymore' (O'ReillyNet)

Federico Biancuzzi talks to Eric Raymond about license issues. "Q:Why did you say we don't need the GPL anymore? A:It's 2005, not 1985. We've learned a lot in the last 20 years. The fears that originally led to the reciprocity stuff in GPL are nowadays, at least in my opinion, baseless. People who do what the GPL tries to prevent (e.g., closed source forks of open source projects) wind up injuring only themselves. They trap themselves unto competing with a small in-house development group against the much larger one in the parent open source project, and failing."

Changes loom for patent process in US, EU (NewsForge)

NewsForge looks at patent reform in the U.S. "Non-obviousness is supposed to be the foundation of the patent system. No invention should be granted a patent if it doesn't contain the "aha" factor - the element of surprise that grabs experts in the technology, causing them to exclaim, "wow! I never thought of that!" Yet, over and over again, the United States Patent and Trademark Office (USPTO) grants patents for algorithms that leave software developers scratching their heads and saying, "that one, we already knew.""

There are hints that the next chapter will be an attempt to pass the so-called "Community" patent. Talk about Orwellian-newspeak. Here's the plan: Lawmakers including Kauppi said the rejection of the legislation should give fresh impetus to the creation of a single European system, known as the ``Community'' patent."

Keeping email under lock and (public) key (NewsForge)

Marcelo Rinesi explains how to encrypt mail archives in a NewsForge article. "With governments and law enforcement organizations pushing for increasingly intrusive monitoring and logging of business email messages, network administrators are put in an uncomfortable situation. Even disregarding privacy implications, such systems pose security problems at least as serious as those they attempt to solve. A "master archive" of emails is after all an extremely tempting target to external hackers, but it also has staggering potential for internal abuse. Ideally, we would want no centralized mail logs, but legal and corporate requirements mandate suitable record-keeping in the case of an internal or external audit. One way to meet both goals is by encrypting the archive using public key cryptography."
