在JavaScript文件中使用Google Analytics谷歌分析的统计代码

在JS文件使用Google Analytics谷歌分析的统计代码-月光博客

　　Google Analytics（谷歌分析）是一个企业级的网络分析解决方案，可以让网站主了解详细的网站流量，不过在使用过程中，很多人碰到这样一个问题，就是不想批量修改原来的静态HTML页面，而是使用外部Javascript文件的方式进行修改，而Google Analytics的代码是无法直接加到JS文件中的。

　　这里介绍一个方法，使用这个方法，就可以直接将Google Analytics（谷歌分析）的代码放到外部JS文件中了。

　　具体方法是，将下面的代码修改为你的ID，然后加入外部JS文件，即可实现在JavaScript文件中使用Google Analytics（谷歌分析）。

document.write('<script src="http://www.google-analytics.com/urchin.js" type="text/javascript"></script>');
function analytics()
{
_uacct = "UA-*******-*";//你的ID
urchinTracker();
}
if (document.all){
window.attachEvent('onload',analytics);
}
else{
window.addEventListener('load',analytics,false);
}

Batch Convert FLV to MP3

Four Loves Four: Batch Convert FLV to MP3

Many times on youtube I find concert videos or acoustic shows that I want to keep for later. Using the Firefox plugin VideoDownloader, I can download these videos as flv files but these flv's are not as portable as mp3. So I searched for a way to convert flv to mp3 and found help on the Ubuntu forums.

After looking at the script and looking at my flv files, I noticed that it would be very inefficient to do each file individually. Therefore, I modified the script to convert a whole folder of flv's. I will show the whole script itself and how to run it, but first lets install some programs that we need in order to convert the flv's.

sudo apt-get install ecasound mpg123 lame ffmpeg

The script itself is the following:

#!/bin/bash
# FLV to MP3
#flv2mp3.sh

FLV_FILE=/home/ditto/Videos/
cd $FLV_FILE

for vid in *.flv
do
ffmpeg -i $vid -f mp3 -vn -acodec copy /tmp/temp.mp3
ecasound -i /tmp/temp.mp3 -etf:8 -o ${vid/.flv}.mp3
rm -f /tmp/temp.mp3
done

exit 0

I save my scripts in a ~/scripts and don't forget to make the script executable.

chmod u+x flv2mp3.sh

Run as follows:

user@home:/scripts~$ ./flv2mp3

Let's take a closer look at the code.

FLV_FILE=/home/ditto/Videos/
cd $FLV_FILE

FLV_FILE is the location of the flv video files that we want to be converted. In the next line, the directory is changed to the location of the videos.

Next, we will look through the files in that directory, only using the .flv files. Notice:

for vid in *.flv

Next we will convert the video to mono audio and create a temporary mp3 called temp.mp3

ffmpeg -i $vid -f mp3 -vn -acodec copy /tmp/temp.mp3

Since the audio by default is mono, we will then convert it to stereo, output it into the current directory, and save it as an mp3, while keeping the basename. The file is renamed by ${vid/.flv}.mp3

ecasound -i /tmp/temp.mp3 -etf:8 -o ${vid/.flv}.mp3
rm -f /tmp/temp.mp3

That is pretty much it. Any comments or ways to make it better, please let me know.

Download YouTube Videos on Linux and Convert FLV to MPG Movies and rip MP3 Audio

Download YouTube Videos on Linux and Convert FLV to MPG Movies and rip MP3 Audio | Webmaster Tips

This tutorial shows how to bulk download YouTube videos on Linux and then convert the FLV files to MPG video and MP3 audio files.

Required Software

I am using Ubuntu Linux, but the concept should be the same for other distros. Make sure you already have all of the multimedia codecs including ffmpeg and mplayer. You will also need to install youtube-dl:

sudo apt-get install youtube-dl

Downloading YouTube Videos on Linux

To download YouTube videos on Linux, use youtube-dl in the terminal like this:

youtube-dl [options] video_url

To see available options type man youtube-dl in a terminal.

Converting YouTube Videos to MPG on Linux

To convert YouTube movies from FLV to MPG on Linux use ffmpeg like this in the terminal:

ffmpeg -i old-file.flv new-file.mpg

Ripping MP3s from YouTube Videos on Linux

It is easy to extract MP3 audio from a YouTube movie on Linux with mplayer.

The method to rip MP3 audio from FLV files with ffmpeg from this site doesn't work on my computer so I use mplayer to do it:

mplayer -dumpaudio old-file.flv -dumpfile new-file.mp3

Automating the Process with a Shell Script

If you want to download a set of YouTube movies and convert them to MP3 audio, or save them as MPG movies on your hard drive, you can automate the process with a shell script.

This is just a quick script showing how it might be done. Use the following code at your own risk, and make sure you understand what it does before doing it. It will delete all the FLV files in the current directory after it processes them.

#!/bin/sh  # This script downloads YouTube videos and converts them # You will end up with an MPG video and MP3 audio of each YouTube movie # You need to install the following three programs: # youtube_dl, ffmpeg, and mplayer  # Use this script at your own risk! # Make sure that you understand how it works before you use it!  # USAGE: # Make a file called videos.txt with the URL of 1 YouTube video on each line. # Don't leave any blank lines in the file # Put the videos.txt file in an empty folder along with this script # run this script with the following commands: # $ ./youtube_downloader.sh # It will take a long time to run, depending on # how many videos you have in your videos.txt file.  while read inputline do   youtube_url="$(echo $inputline)"   youtube-dl $youtube_url done < videos.txt  # Convert the flv files to mpg and mp3 files for i in *.flv do   ffmpeg -i $i $i.mpg   # comment out the next line if you don't want MP3's extracted   mplayer -dumpaudio $i -dumpfile $i.mp3   # The next line deletes all FLV files in the current directory to cleanup   rm $i done

Want To Impress Your Friends? Run Chrome OS

Want To Impress Your Friends? Run Chrome OS

We have all read the news that Google is planning to enter the operating system market with their soon to be released Google Chrome OS which is initially targeting the netbook market. Google Chrome OS is based on Google's web browser Google Chrome and a Linux kernel. Little information are know as of yet. The ones that are available state that Google Chrome OS will be released as Open Source, that it will use a minimalistic design and that it will likely be released in the second half of 2010.

Fake videos showcasing the new Google Chrome OS have been making their rounds on the Internet in the last months. There have not been on the other hand lots of attempts to turn an existing Linux distribution into something that resembles the Google Chrome OS.

Chrome OS is one of the first attempts. It is offered as a Live CD and virtual image currently. Chrome OS uses a GNOME 2.24 desktop environment with the Google Chrome 4.0.207 web browser integrated. Several other programs like Open Office or Flash Player have also been integrated into the distribution.

To be 100% clear here. This is a custom Linux distribution and not the official Google Chrome OS. It still resembles the operating system and can be used as a Live CD to run the Google Chrome web browser on Linux. Interested users can download the Live CD or the virtual image from the Chrome OS Linux website.

Download Youtube Videos

Download Youtube Videos

Many Internet users want to download Youtube videos. Downloading the videos can be beneficial in several ways including the option to play the video at any time without having to access the Youtube website on the Internet. It can also save bandwidth and be used to transfer the Youtube videos to devices like cell phones, media players or gaming systems that are usually not connected to the Internet or that do not offer the speed needed to enjoy the videos.

There are basically three ways of downloading Youtube videos: Using a web service, a web browser add-on or a standalone software program. All methods have their distinct advantages and disadvantages. Web services for example are usually independent of operating systems and can be used instantly without having to install software.They do usually lack the ability to download multiple Youtube videos at once.

Web browser plugins require installation. They have the advantage that they work directly on the site which is very comfortable for the user. They also usually do not provide the means to add multiple videos at once to a download queue.

Software programs to download Youtube videos usually come with the option to add multiple video links to the queue before starting the download. They do need to be installed on the other hand and lack a solid Youtube browser sometimes.

Online services to download Youtube videos:

Web services are websites that provide the means to download Youtube videos to a local computer system. Some offer advanced features like converting the video to another format. The list has been limited to ten free services that provide options to download Youtube videos.

1. Keepvid: A straightforward service. The user needs to paste the url of the Youtube video in the form provided on the website. Keepvid will then offer low quality and high quality downloads of the video. Works with other video portals like MySpace video or Dailymotion as well. Offers a bookmarklet which works more comfortably than copying pasting Youtube urls.
