RAD Studio 2010, Delphi 2010 and C++Builder 2010 enable developers to build touch based GUI, tablet, touchpad, and kiosk applications.

本周出现的2010版本的Delphi或RAD Studio已经可以支持用户开发支持触摸的程序了。

The flexible touch enabled framework that seamlessly supports multiple versions of Windows including Windows 2000, XP, Vista and Windows 7; and works with a variety of inputs including single and multi touch screens, pen, and mouse.

See how to::

  • Create gesture and touch enabled applications in just a few easy steps
  • Get a quick start with more than 30 included gestures like left, right, up, down, scratch-out, and interactive multi-touch gestures like pan, zoom, and rotate
  • Use the Gesture Designer to visually add your own custom gestures
  • Use the virtual touch, multi-locale, and multi-language keyboard for on-screen input
  • Upgrade existing Delphi and C++Builder applications to add support for touch and gesture input with little or no additional coding


FreeBSD Xen 3.0 配置指南



FreeBSD Xen 3.0 配置指南

这个是从一个老外的站点上弄来的,希望能对想在FreeBSD下使用Xen 3.0的朋友起到点帮助。
This file is extremely dated at this point.

One should be able to build by running the setup script and then running the build
script on a machine running freebsd.

Also be aware that I have done nothing to fix bugs here in over 8 months. Currently
my efforts are going towards getting FreeBSD -CURRENT up and running on xen 3.0.

This assumes that you are running Xen 2.0 testing

Running the current image:
1) download kernel, mdroot-5.3-small.gz, freebsd.sample, and xenargs.sample
2) uncompress the kernel and mdroot (the mdroot requires 406MB uncompressed)
3) export the mdroot as a loopback device:
> /sbin/losetup /dev/loopa /var/mdroot
(This may not work if you have an older losetup – FC2 is known to work)
4) localize the freebsd.sample to your environment
5) run the xenargs.sample script
6) There is no root password
— If you have problems you can boot into single user mode (look at the options in
freebsd.sample) and edit /etc/rc.conf to reflect your environment

Building the current image:
1) on a machine running FreeBSD 5.3 download i386-xeno.tgz
# cd /sys
# tar xzf ~/i386-xeno.tgz
# cd conf
(assumes csh)
# foreach file ( ../i386-xeno/sys/conf/*.i386-xeno )
foreach? ln -s $file
# cd ../i386-xeno/conf/
—– # create compile directory ——-
# config XENCONF
Kernel build directory is ../compile/XENCONF
Don’t forget to do a “make depend”
# cd ../../include/
—– # link in xen interface headers ——-
# ln -s /t/niners/users/xen/xen-2.0-testing.bk/xen/include/public hypervisor-ifs
# cd ../compile/XENCONF
# make kernel-depend
—– # build kernel ——-
# make -j4 kernel

我们已经比较了32位和64位Ubuntu的性能, 而且现在已经开始撰写Ubuntu/Kubuntu/Xubuntu的性能比较(已发布第一部分), 那么即将发布的Feisty Fawn和Fedora 7的性能比较将会如何呢? 本文主要介绍了Fedora Core 6, Ubuntu 6.10 Edgy Eft, Fedora 7 Test 2和Ubuntu Feisty Fawn Herd 5的性能评测. 在游戏和桌面方面, 哪一个Linux发行版表现的更出色呢? 今天我将回答这些问题.
