 News and Editorials
 
    DirectFB.  Sven Neumann, one of the many wonderful GIMP developers
    I've met over the years, wrote recently to let me know that his
    company, [15]convergence integrated media had released a bit of code
    as open source. [16]DirectFB is a hardware abstraction layer for
    embedded systems that makes use of the Linux framebuffer to provide
    hardware graphics acceleration, support for various input devices and
    an integrated windowing environment with support for translucent
    windows.
    
    The need for such hardware abstraction may not be obvious - after all,
    what is the framebuffer but an [17]abstraction for the graphics
    hardware (according to the Framebuffer HOWTO). Both provide hardware
    independence (required by platforms like PowerPC and Sparc which gave
    rise to the original Linux framebuffer work). The real difference
    between the generic Linux framebuffer and DirectFB is that the latter
    provides graphics primitives not currently available to the former,
    not the least of which is alpha blending, otherwise known as
    transparent windows.
    
    DirectFB provides access to various media formats using external
    modules to allow applications to load images, video and fonts. At the
    moment, PNG, JPEG and GIF images are directly supported. AVI movies
    can be read using the avifile module and other video devices are
    supported using the Video4Linux (V4l) interface. FreeType2 is used to
    render all fonts and provides antialiased font rendering to DirectFB.
    
    While DirectFB provides its own [18]window layering functions, it also
    has a backend version of GDK, the platform specific layer of the GTK+
    library stack. That means that GTK+ programs can run on DirectFB
    ([19]screenshot), and thus embedded devices, without the overhead of
    X. At the moment, however, only one application can access the
    framebuffer at a time.
    
    Just recently the open-sourced version of DirectFB was added to the
    Debian unstable branch, meaning that it has found at least a potential
    home in the open source Linux distribution world. Whether or not this
    means DirectFB will find wide spread acceptance has yet to be seen. In
    the meantime, Sven and friends will continue their work, hoping for an
    embedded solution for graphics tools.
    
    Noted in passing.  The KDE team is planning on releasing
    [20]kdelibs-2.1.2 early next week after discovering that the
    just-released KOffice 1.1beta1 was having problems with the current
    libraries.
    
 Documentation
 
    LDP Weekly News for 2001-04-24. This weeks [21]Linux Documentation
    Project Weekly News includes two new documents: the MP3 Player Box
    HOWTO and the Connecting to MS SQL 6.x+ via Openlink/PHP/ODBC
    mini-HOWTO
    
 Electronics
 
    Simputer team interview (O.C. News). The [22]Simputer team, designers
    of a GPL hardware platform, took some time this week for an interview
    by Open Collector News. "Our design is very different to the Intel
    reference design. Where the two designs might look alike, as in how
    the Flash is connected to the SA1110 for example, there is only one
    way to do it and this is clearly indicated in the data sheets, apart
    from the reference design."
    
 Embedded Systems
 
    Embedded Linux Newsletter for Apr. 26, 2001 (LinuxDevices). The weekly
    [23]summary of the Embedded Linux world came this week by way of
    LinuxDevices.com. Features included a developers view of the new
    Agenda V3 Linux-based handheld system and an open camera server
    project.
    
    Embedded Linux Newsletter (LinuxDevices). Too late for last weeks
    Weekly Edition of LWN.net, the previous weeks summary of the
    [24]Embedded Linux marketplace was also posted at LinuxDevices.com.
    Topics that week included Inder Singh's view of the ELC Platform
    Specification and a sneak peek at Linux based cellphone/PDAs.
    
 Interoperability
 
    WINE Kernel Cousin returns. Brian Vincent wrote with news that he has
    taken over the [25]WINE Kernel Cousin production, with his first issue
    already out and another due soon.
    
    New Samba improves Windows mimicry (News.com). C|Net reports on
    [26]the latest release from the Samba team. "The software offers cost
    savings not only because customers don't have to pay for the server
    operating system, but also because they don't have to pay "client"
    license fees for all the computers that use the server." (Thanks to
    Cesar A. K. Grossmann)
    
    Samba 2.2: your way to Windows file/print services (ZDNet). Excited by
    the better integration with Windows, ZDNet reviewed [27]the latest
    release from the Samba team. "Samba has always done exceptionally well
    at enabling MS-DOS and Windows systems to use Unix file/print servers
    exactly as if they were NT servers. This new version enhances its
    basic abilities by enabling a Samba server to act as an authentication
    source for both W2K and NT clients."
    
 Network Management
 
    OpenNMS Update, Vol 2., Issue 17. The [28]OpenNMS Update for the week
    of April 24, 2001 includes a quick tip on process dependencies and
    SNMP threshold configuration.
    
    New EVMS released. The [29]Enterprise Volume Management System Project
    released a new snapshot of their project this past week.
    
 Science
 
    Biology Yearns to Be Free (Wired). Wired News compared [30]closed
    source and open source models in the world of molecular biology.
    "Applications in biology -- which include technologies from operating
    systems to gene databases -- in an open-source environment would give
    the best minds access to the information they need to invent new
    technologies and improve those that exist."
    
 Software Development
 
    Guikachu, resource editor for PalmOS files. A new release of
    [31]Guikachu, a GNOME application for graphical editing of resource
    files for PalmOS-based pocket computers, has been made available from
    the project web site.
    
 Standards
 
    Khronos Group Completes OpenML 1.0 Specification. The Khronos Group, a
    consortium of digital media and graphics companies consisting of
    3Dlabs, ATI, Discreet, Evans & Sutherland, Intel, NVIDIA, SGI and Sun
    Microsystems Inc., announced the delivery of [32]the OpenML 1.0
    specification. OpenML is a software environment that is complementary
    to the peer OpenGL API designed for digital content authoring across
    multiple operating systems and hardware platforms.
    
    Commercial implementations of OpenML 1.0 are expected on Linux and
    other OS environments with shipments starting later this year.
    
 System Administration
 
    Omni 0.1. Following in line with the past two weeks, a new release of
    the [33]Omni package was made available by the Omni Project this week.
    Omni is the package of printer drivers designed to work within the
    Ghostscript framework.

    Zope 2.3.2 beta 2 released. Zope.org released the second beta version
    of the [34]2.3.2 release this past week. [35]Changes for this release
    have also been posted. If no other serious problems are found they
    expect to make the final release on Friday, April 27th.
    
    A new dictionary interface, ZDictionary, has also been released. A
    [36]sample implementation has been placed online.
    
    Zope Newbies for Aprl 25th. A new issue of [37]Zope Newbies has been
    published at the Zope Newbies website. News of note include a fix for
    using Konqueror with Zope, a link to a Zope Talk of particularly good
    quality, and news on using Zope on OpenBSD.
    
    Zope and MySQL e-book. Beehive has announced the release of an English
    language version of its e-book titled [38]Zope and MySQL.
    
    Generic Sort External Method for Zope. Oleg Broytmann has written a
    [39]generic sort external method for Zope, as posted to their
    discussion site.
    
 Window Systems
 
    The Linux GFX project. A group of developers has decided that XFree86
    is never going to produce the graphics environment they want, so they
    have gone off and [40]announced the Linux GFX project. Its plan is to
    develop a new X server from scratch which is oriented around
    performance and have "a faster development cycle." People are already
    questioning whether it makes sense to start a new, competing project
    of this magnitude, but the Linux GFX folks seem to be determined. See
    the announcement if you would like to join their mailing list.

 Perl
 
    If You Don't Know Perl, You Don't Know Dick (Linux.com). Linux.com
    [60]talks with Dick Hardt, founder and CEO of ActiveState. "A great
    deal of our revenue so far has been around the 'bottled-water'
    business model, where we provide quality-assured versions of Perl for
    vendors that want us to have Perl work well or better with a
    particular technology of theirs. In this case we almost always
    invariably roll that out as open-source technology."
    
    Quick Start Guide With SOAP and SOAP::Lite Part Two (Perl.com). Paul
    Kulchenko takes a deeper look at [61]SOAP clients and servers in part
    2 of this article on perl.com. "Another lightweight solution might be
    to implement the SOAP service as an HTTP daemon; in that case, you
    don't need to use a separate Web server. This might be useful in a
    situation where a client application accepts SOAP calls, or for
    internal usage."
    
    This week on perl5-porters(Perl.com). This weeks [62]Perl5 Porters
    summary includes notes on quality control, placing modules in the
    core, regex debugger and ithreads.
