The core ORB is written in C, and runs under Linux, UNIX (BSD, Solaris, HP-UX, ...), and Windows.
It is supported by Red Hat and Ximian as middleware of the GNOME project.
Enhancements:
- Fix GIOP timeouts and add unit tests (Jules Colding)
- Code cleanups (Kjartan)

X/OS Linux is derived from the Free/Open Source rpm packages of Red Hat Enterprise Linux 4 (RHEL4) under the requirements set forth by their trademark policy.

X/OS has spent considerable effort to avoid using Red Hats trademarks in any way that would imply an association with or sponsorship by Red Hat.

After some delay, the final release of X/OS Linux 4.0 is now available to the public.

The X/OS Linux team has spent considerable effort to assure the label enterprise-grade Linux for this milestone release. With the simultaneous availability of X/OS Linux 4.0 for x86 and x86_64 processor architectures, it delivers the latest “best-of-breed” Free and Open Source software for both 32- and 64-bit platforms.

Highlights include the 2.6 Linux kernel featuring numerous enhancements over the previous 2.4 version, Security Enhanced Linux (SELinux) to apply more granular security policies, improved storage capabilities supporting file systems of up to 8TB and more.

The Global File System (GFS) and Cluster Suite software is included in this release to ease the task of creating and managing advanced cluster configurations, and is available as an extra option during installation. This powerful set of tools provides seamless scalability of applications such as databases, web servers and high-performance computing clusters — with GFS enabling nodes to simultaneously read and write to a single shared filesystem.

Next to providing an advanced server platform, X/OS Linux 4.0 adds various enhancements to the desktop — increasing usability with greatly improved office productivity tools, plug-and-play USB device recognition and power management supporting the ACPI standard.

In addition to compatibility with the de facto distribution for deploying Linux in the enterprise, X/OS Linux strides to include various other useful packages and tools that conform to the standard for mature and robust “enterprise-grade” software. One example is Xfce, an extra option in addition to Gnome and KDE, offering a light-weight desktop environment suited for use on low-end or thin client systems.

D is a high-level language derived from C and C++ but is not backwards-compatible with either. GDC is a frontend for D written for GCC.
Supported Systems:
GCC 3.3.x, 3.4.x, 4.0.x
Linux (tested on Red Hat 7.2, 8)
Mac OS X 10.3.x, 10.4.x
FreeBSD 5.2.1
Cygwin
MinGW
AIX (tested on 5.1)
Similar versions should work and other Unix platforms may work. Although the compiler will probably work on most 32-bit architectures, the D runtime library will still need to be updated to support them.
Enhancements:
- Support for 64-bit targets was added.
- Multilib support was added.
- DMD was updated to 1.007.
- Minor bugs were fixed.

Spreadsheet::WriteExcelXML is a Perl module that can create an Excel file in XML format.

SYNOPSIS

To write a string, a formatted string, a number and a formula to the first worksheet in an Excel XML spreadsheet called perl.xls:

use Spreadsheet::WriteExcelXML;

# Create a new Excel workbook
my $workbook = Spreadsheet::WriteExcelXML->new("perl.xls");

# Add a worksheet
$worksheet = $workbook->add_worksheet();

# Add and define a format
$format = $workbook->add_format(); # Add a format
$format->set_bold();
$format->set_color(red);
$format->set_align(center);

# Write a formatted and unformatted string, row and column notation.
$col = $row = 0;
$worksheet->write($row, $col, "Hi Excel!", $format);
$worksheet->write(1, $col, "Hi Excel!");

# Write a number and a formula using A1 notation
$worksheet->write(A3, 1.2345);
$worksheet->write(A4, =SIN(PI()/4));

The Spreadsheet::WriteExcelXML module can be used to create an Excel file in XML format. The Excel XML format is supported in Excel 2002 and 2003.

Multiple worksheets can be added to a workbook and formatting can be applied to cells. Text, numbers, and formulas can be written to the cells. The module supports strings up to 32,767 characters and the strings can be in UTF8 format.

Spreadsheet::WriteExcelXML uses the same interface as Spreadsheet::WriteExcel.
This module cannot, as yet, be used to write to an existing Excel XML file.
