List of free and open source software packages

List of free and open source software packages - Wikipedia, the free encyclopedia
From Wikipedia, the free encyclopedia
Jump to: navigation, search

This is a list of software free to be modified and distributed, for the software free in the monetary sense List of freeware.

This is a list of free and open source software packages: computer software licensed under free software licenses and open source licenses. Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open source. For more information about the philosophical background for open source software, see free software movement and Open Source Initiative. However, nearly all software meeting the Free Software Definition also meets the Open Source Definition and vice versa. A small fraction of the software that meets either definition is listed here.

Best of Open Source Software Awards 2009

InfoWorld's 2009 Bossies spotlight today's Top 40 open source products for business and IT pros

If you think you can easily whittle down the best open source software to a manageable number, you'll soon discover that you can't do it without a great deal of hair pulling, nail biting, and gnashing of teeth. There are just too many excellent tools. Even if you give up on a "manageable" number and go whole hog -- say, a top 100, which is certainly doable -- you'll still face too many hard decisions and too many arguments. You'll be looking for a way out.

To bring you this year's 40 top open source products -- our 2009 Bossie winners -- we pulled a couple of fast ones. Our first inspired dodge was to come up with the InfoWorld Open Source Hall of Fame. There's a certain number of obviously great open source solutions (we settled on 36) that deserve a hall of fame, and though our annual Bossies selection regularly passed over most of these because of their sheer obviousness, a few inevitably complicated the process. Erecting the hall of fame allowed us to honor these inconvenient legends -- the Linuxes, BSDs, Sendmails, and Snorts -- once and for all.

[ See the slideshows of the 2009 InfoWorld Bossie Award winners: The best of open source developer tools | The best of open source enterprise software | The best of open source networking software | The best of open source platforms and middleware. ]

Our second shortcut was to omit desktop productivity tools and focus strictly on enterprise software, application development tools, networking and network management software, and platforms and middleware. We covered some of the top desktop productivity tools in "The best free open source software for Windows" -- including Linux standards such as OpenOffice.org and Firefox -- but there's so much more to talk about. Once you start down this road, you have to walk a long way.

php中?(问号)和:(冒号)的作用--Ajax中国

C语言里的语法,条件表达式e1?e2:e3,就是一个if语句的缩写,若e1为真(非0),则此表达式的值为e2的值;若为假,则表达式的值为e3。等同于
  1. $e="";
  2. if(e1)
  3. {
  4. $e=e2;
  5. }
  6. else
  7. {
  8. $e=e3;

Free shipping at over 700 online stores today

CANOE Money - News: Free shipping at over 700 online stores today

If you're like many Canadians and haven't started holiday shopping yet, consider taking advantage of free shipping day today at more than 700 online retailers.

All of this year's 726 participants, such as the Apple Store, Lululemon Athletica and The Body Shop, promise delivery by Christmas Eve.

The event began last year to extend the cyber shopping season for merchants and give procrastinators one last chance to order gifts before Dec. 24.

And many Canadians are last minute shoppers. According to a TD First Class Visa Holiday Shopping Survey released today, 38% of us put off our shopping because we're busy while another 11% admit we're lazy when it comes to facing the crowds.

The online promotion has nearly tripled in popularity this year from the just 250 retailers that took part in 2008.

Canadians should read online fine print carefully since certain restrictions may apply to shipping addresses outside of the U.S.

SocksCap代理使用教程

SocksCap代理使用教程-月光博客

  很多使用SSH的用户都会遇到这样的问题,为什么我已经设置了socks代理,还设置了OpenDNS,怎么还是上不了Facebook,这就涉及到DNS污染技术,需要用户使用远程解析域名的方法才能访问目标网站。

  对于Firefox来说,远程解析域名的设置非常简单,只要在about:config修改network.proxy.socks_remote_dns=true就可以了。但对于IE和其他软件来说,就没有类似的修改方法,需要使用一个名为SocksCap的代理软件来解决这个问题。

  SocksCap是一个通过Socks代理连接网络的代理服务器第三方支持软件,拥有功能强大的Socks调度,所有Windows应用(如IE、Firefox、QQ、FTP等)都可以使用这个Socks代理工具通过Socks代理服务器上网,即使不支持Socks代理的应用也可以用Socks代理上网。

  首先下载安装SocksCap,安装结束后,运行SocksCap,出现如下图所示界面,这时候需要进行一些配置工作,选择菜单File - Settings。

SocksCap代理

  在Socks Server中填入Socks代理的IP地址:127.0.0.1,在Port项中填入代理端口:1080;Protocol选择Socks5项,选中Resolve all names remot,点击"确定"。

SocksCap代理

  接下来要做的便是把应用程序加入到SocksCap中。点File - New选项就可以出现如下图窗口。

SocksCap代理

  点Browse浏览选择应用程序,如IE等应用的EXE文件,其他选择默认,点"OK"就可以完成配置。

  更简便的操作方法是将应用程序的快捷图标拖入主窗口中既可,然后鼠标右键会显示"New application profile",给这个应用命名,然后给出要运行的程序和工作目录,点"OK"设置生效。

  这时候的SocksCap主界面会如下图所示,列出一系列应用程序的图标。

SocksCap代理

  双击SocksCap主界面的应用程序图标,即可通过SocksCap运行应用程序。若双击桌面上的应用程序,则为不使用代理运行程序。

  总体来说,SocksCap代理的目的是把一些不支持socks的代理的软件在进行网络通信的时候的数据全部转化成socks代理数据,然后再通过代理出去。对于IE来说,不需要在IE里面做任何配置,只要从SocksCap中运行IE就可以支持Socks代理。

Review: 3 top Linux distros go for different users

Review: 3 top Linux distros go for different users

Fedora, openSUSE and Ubuntu Linux desktops may look alike, but they've got some important distinctions.
Steven J. Vaughan-Nichols

December 16, 2009 (Computerworld) At first glance, there's little to differentiate between the latest releases of the top Linux distributions: Red Hat's Fedora 12, Novell's openSUSE 11.2 and Canonical's Ubuntu 9.10. They each use the latest releases of open-source applications and are based on recent Linux kernels. Each of the distros also includes open-source applications such as OpenOffice and Firefox. However, a closer look reveals real differences -- in fact, each is meant for a different audience.

Underneath the hood, each of the three uses the 2.6.31 Linux kernel, but above that, their differences begin to surface. Fedora and Ubuntu, for example, use GNOME 2.28 (the latest version) for their default desktop, while openSUSE uses KDE 4.3.1.

(略......)

Conclusions

If you're a Linux expert, Fedora is for you. If you just want a good, general-purpose desktop for home or work, then openSUSE is your best pick. And if you're new to Linux, and your computer gets along well with Ubuntu, Ubuntu is still a good choice.
