Well everyone uses youtube and everytime we find a need to download a clip from there. Unfortunately google doesnt provide a download button for that, but still no need to be sad…there are a lot of ways to get it done. There are online methods, browzer plugins and applications doing the same. Each has its own advantages and disadvantages.Anyway I will be discussing a few options.

You are working always on ur home PC, then its better to use an application software since it provides a lot of features. The one I would recommend is the orbit downloader . Its a regular download manager that can even handle torrents. Use the grab ++ feature in it and it lists all the embedded videos whenever u open a page in ur browser. Now u can select which all do u want and then either download or schedule for download the same. It supports almost all the browsers available in the market.And it works for any webpage with embedded media and not just youtube.

Now comes the browzer plugin thing. Its best if u are moving around but still carrying ur browzer (portable browzer) along with u in a USB or something like that. The best one I’d suggest is a Firefox plugin called Video DownloadHelper 4.3 . This one will do the trick.

Now for the last option, and that will be to use an online downloader. Pretty unreliable compared to others but still when u are on the move and the other options are not available this one saves the day. Among the online downloaders I prefferhttp://youtubedownloader.org/ . The site alsp provides both the aforementioned options as well. Now u have options to directly convert them into avi,mp4,3gp, mov or mp3 formats. So good for those out there who hate the FLV format. Hmm, me too hate flv.

I think you got whatever you were looking for…see ya..

Is it a linux machine and you dont want your kids to be in some specific site,say facebook.com…well then you can put a list of those sites in the /etc/hosts file and add the following into it.

127.0.0.1        www.facebook.com

127.0.0.1        www.anysite.com

Yes its not a big deal but that would come handy for home use.

So happy spying.

PS: Needless to say I din invent any of these.I was just sharing something I read from some site while I was on blind surfing.

1. System beeps: Sick of those system beeps.Well then tell them to shut up.Here is the command. Type in the command setterm -blength 0 in the terminal.You will no longer hear a beep in that session. If you dont want to type it all the time, then add it to the system startup as mentioned in trivia#2. Have some peace of mind.

2.Command History: As you all know command history is a handy tool when using a terminal. But sometimes you will notice that the command u are looking for is already gone from the history.Well, to avoid it, you better set the size of the history archive by putting the following in the .bashrc file:

HISTSIZE=999

HISTFILESIZE=999

Oh,if that looks like a too big archive to search for a command,then u can always make use of grep. The command will be like:

history | grep -i str

where str is a part of the command u are looking for. So no more forgotten commands in your life.

PS: You can unset the value of HISTSIZE and HISTFILESIZE to permenantly keep a history of all commands ever used, but its not recommended for obvious reasons.
