Download flash videos in Ubuntu without any application

Here is a simple trick that you can use to download your favourite flash videos from Youtube or metacafe without any application. You can stop your search for an apt application for downloading youtube videos... installing it on linux...Just leave everything...

Just login to the youtube and click on some videos to play it.


While the video is streaming, check the /tmp folder in the Ubuntu's file system. There you can see the same video file being updated with filename like Flash26YGf2.flv


You can copy this video file to some other place to make it viewed later. If you reload the the webpage or open some other video in the same tab/window of the web browser then the previous video file will be overwritten with the new one. So better is to copy the flash video file just after it is completely buffered in the web browser.


This tip has one another advantage too. If you want to see the end part of a flash video file which is about 1 hour length, you dont need to download the complete video from the beginning. You can seek the video into desired portion in the website. Then video file in the tmp directory will be starting from the new positon to which you seeked it.


So this technique is simple and cool where you need only a flash video player embedded in the web browser only to save the video. This methode can be used in situation where you  can play  video but blocked from downloading it since you have no account registered in those websites.

How to assign an IP address in Ubuntu using command line

Computers may be assiged a static IP address or assigned one dynamically. Typically servers and institutions will use a static IP which will not change each time u get connected. Workstation will use Dynamic Host Configuration Protocol (DHCP) for IP address assignment. It is more easily to find a system if the IP address does not change and is static.


Use the Command Line:

    /sbin/ifconfig eth0 192.168.10.12 netmask 255.255.255.0 broadcast 192.168.10.255                  

 
The ifconfig command does NOT store this information permanently. Upon reboot this information is lost. Manually add the network configuration to /etc/network/interfaces  as shown in my next post .

Things to care when you buy a laptop from Kerala

Probably laptop is a an avoidable tech think when you live in a todays professional technical life. The laptop market is making a noticable growth in a recent period.

The giants among the field are Sony, Apple etc.. Hp is also a good option at this range. U may get greatly appealing, light weight systems if you have enough money to pay  an amount for greater than 50k rupees.

Dell, Thoshiba makes the middle part of the laptop industry by providing computeras with reasonable configuration at nominal price range of 35k-45k. Lenovo was also there in this range till last year, but they are not a preferable option now if you are lookig to invest for a laptop in this range. U may get a professional system that compensates both multimedia experience as well as study purposes in this level.

But when it comes to the next layer you may get cheaper laptops  but with attractive configurations. But they try hard to compete with the quality of laptops that constitutes upper layers. Acer, Compaq falls in this category.

Let our discussion zoom into the middle layer. If you are looking to buy a laptop in kerala, contact as many shops as possible before messing up with head ache. Most of the brands have their own showrooms throughout Kerala. Please dont fall in illusions created  by the "offers" given by the shoppees. Probably they charge you for these offers.

In the middle level Dell is the favourite option for many of them. If you are going to buy a Dell, its better to avoid direct purchasing from some local shoppes here. You will get new dell at a price difference of 4,000 rupees if you select online purchase. Probably kerala people hesitate to perform an online money transfer becoz they are unware and unconvinced of the security of payement... 

So keep on with your manifestos... If you are not much courageous for a direct deal, make the deal with some direct vendors, they purchase the laptop online and transfer it to you. Visit the Dell's website for laptop models by clicking here. At the first they will give quotation for the model you have  specified, you can proceed by taking a DD payable to DELL INDIA (P) LTD at banglore. Transfer it to the online vendor along with your copy of DD and ID proof. They do the rest and you will get your brand new laptop at home (is it good enough???). The vendor will give warranty to you probably for one year with options of  extending it later.

Mozad Infoways is a good option if you are located near the Cochin city. (i have purchased). U get the system shipped (sorry!!!) from the dell factory at Sreeperumpathur. If you purchase the same from some local computer shoppees you may have to pay around 4k rupees additionally....

Similarly all the brands have direct dealors and vendors. Try to find out them to make the purchase without wasting money...
