Google+有一个秘密武器(译)

Are you on Google Plus? If you are, are you actually using it?

You should be – because Google Plus offers users an amazing secret weapon.

A little more than a year ago, Google launched its version of a social network. But the network did not gain quick acceptance, and now it seems like it might be going the way of other failed social media ventures like iTunes’ Ping, the long-abandoned MySpace, and the long-forgotten Friendster.

But we should all hope Google Plus sticks around, because it offers perhaps the best feature of any social network – the Hangout.

If you’re not familiar, the Hangout is Google Plus’s tool for video chatting. It’s a unique feature that more prominent social networks like Facebook and Twitter don’t offer.
I’ve found that a Hangout is just as easy to use as Skype or Facetime, with comparable video quality.

But the Hangout is an even better tool than those services, because it offers the additional benefit of easily adding multiple people to a call. In the past, that kind of video-conferencing is something you could only get through pay services.

This is a huge benefit to businesses that work from a distance and need to use video conferencing services, but don’t have a budget to pay for them. Plus, a recent update made the Hangout feature  easier to use through Google Plus’s iPhone app. The app shows you video of who’s talking (as well as of you), while allowing you to toggle to see other users.

Because the app is only showing one video stream at a time, I’ve found that it provides better video quality than the desktop version. In fact, I’ve gotten to the point where I use the app for Hangouts even when my desktop is sitting right beside me.

Plus, you can use the Hangout feature on data networks, not just on WiFi. A couple of times, when I’ve been running late for a meeting by Hangout, I’ve used the app in the car to listen in while driving. (Of course, I didn’t watch the screen while behind the wheel – but the video was available had I had a chauffeur.)

Google Plus offers even more Hangout functionality in its iPad app and in its Android app by showing additional users. I haven’t tried these but would be interested to hear how well the video quality holds up.

All versions of the app are free.

Google Plus is using Hangouts to promote the network by offering hangouts with celebrities, athletes, bands, and more. Plus, the NFL’s website offered fantasy football drafts by hangout this year. Events like these are a great way to try out the Hangout feature to see just how much you’ll like it.

As easy as it is to set up Google Plus – if you have a Gmail address, it takes just a click or two – there’s no reason not to join up, if only to have access to the Hangouts.
Then you can make Google Plus’s secret weapon your own.

Perl语言介绍-动态语言程序设计1

1. 解释型语言,需要解析器和虚拟机
2. 动态数据,不需要数据类型的声明
3. 不需要编译
4. 调用库往往是源码

1. 功能强大
2. 容易学习
3. 容易使用
4. 开放源代码
5. 跨平台

open(F, $filename);
 $m = join(“”, );
 @m = split(/\s+/, $m);

F = open(filename, ‘r’)
n = F.read().split()

open(File,"");
while($Line=){
 chomp($Line);
 ($Word,$Trans)=split("=>",$Line);
 $hashDict{$Word}=$Trans; 
}
close(File);
print "Pls Input word:\n";
$ForSearch=);
if ( defined $hashDict{$ForSearch} ){
  print "$hashDict{$ForSearch}\n";
}else{
  print "$ForSearch is not in the dict!\n";
}

1. Larry Wall于1987年，为文本处理编写。
2. 结合了C，sh， awk和sed的有点。
3. 开放源代码，免费下载安装程序。
4. 解释性的脚本语言
5. Perl不是GUI程序。

1. 出色卓越的处理文本能力。
2. 特别适合于CGI编程
3. 跨平台的编程语言，window，linux…
4. 自主内存管理，没有内存泄漏问题。
5. 强大便捷的模块化功能。
