Từ hộp Mẹo: Trích xuất âm thanh từ bất kỳ video nào bằng VLC, lén lút xung quanh thanh toán và trì hoãn Windows Live Mesh trong khi khởi động.

VLC is not just a Media Player, it is a whole software in itself.This is just an experiment which I did to try and get an MP3 file from a video I downloaded from YouTube.

VLC has a very easy way to convert the FLV (or any other video file for that sake) to MP3

All you need to do is:

1. Open VLC.
2. Go to Media –> Convert/Save.
3. When you click Convert/Save, it opens a dialog box where in you can select the file which you need to convert(i.e. the video/FLV file which you wish to convert to MP3).
4. After selecting the file click on Convert/Save button located in the lower right hand side of the dialog box.
5. After this,there would be a dialog box for Stream Output. Check the option ‘File’, and go to ‘Browse’ to locally save the file with the filename of your choosing. Whenever you enter the new file name and click Save, a “.ps” is appended at the end of the file name. Substitute the “.ps” extension with a “.mp3” extension.
6. In the Settings section of the Convert dialog box there is Profile drop down menu. Within the Profile section pull the menu down and select MP3 (for MP3encoding).
7. Click SAVE and let the data Stream. Once finished, open the MP3 file and enjoy.

I’m an admitted news junkie. I use the Google Alert feature in G-mail to hone in on the subjects I’m interested in. Most sites offer free content and some request a sign in… usually free.

But, there is a few sites that want you to pay for the privilege of reading their articles. Two I can remember off hand is the “Wall Street Journal” and “Financial Times”. Why they insist on paying customers while everyone else does not… I have no idea. Generally the first paragraph is seen and that’s all. A tease.

There is a work around. At the bottom of each article Google has a link saying, “See all stories on this topic”. By clicking that link you get all the related articles available. You also get a new link to the site that was previously partially blocked. This link however is the full article with no requirements!

I have an easy fix to prevent Windows Live Mesh (WLM) from starting at logon (Windows 7) but still being able to sign-in automatically when started manually. I needed this fix as I wanted to sync encrypted volumes that required a password after logon. WLM would fail at login as it couldn’t find the volume specified to sync.

WLM cannot be disabled to start at login if the option “sign-in automatically” is checked. I found that with this option checked WLM would write the startup run registry key (as below) whenever it was executed. I found steps 2-5 here, to give credit where it’s due. Key written by WLM whenever it is executed (with option “sign-in automatically” checked):

[HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun]

“WLSync”=””C:\Program Files (x86)\Windows Live\Mesh\WLSync.exe” /background”

Anyhow, fix is as follows.

1. To delete the registry key, create a batch file that executes the command:

Reg Delete “HKCUSoftwareMicrosoftWindowsCurrentVersionRun” /v WLSync /f

2. To run this script at Windows 7 Logoff:

Type “Gpedit.msc” in the Start Button Run box and press “Enter. This opens the Group Policy Editor.

3. Navigate to “User ConfigurationWindows SettingsScripts (Logon/Logoff)” on the left pane. Double-click “Logoff” on the right-pane to bring up the properties.

4. Click “Add.” This loads an Add a Script dialog. Click “Browse” and select the script you made. This places it in the “Script Name” field.

5.Click “OK” at the bottom of the Add a Script dialog to confirm. This takes you back to the properties window. Click “Apply” at the bottom and close your policy editor. The script will run when the user logs off.
