What is TCP MULTIPATH and how does MULTIPATH in TCP work

Multipath TCP

Every day we read some or the other technical stuff online that we feel like will be a boom in the coming days. Most of the times the stuff we stumble upon will only be a modified version of an already existing thing, or say a re-engineered version of an already existing one.

 

But in recent days I stumbled upon a major improvement in the networking field, that will surely become a major leap in the way communication systems are designed today.

Installing Ubuntu Inside Windows as an Application

ubuntu inside windows

Recently one of our Facebook friend asked us about a way to install Linux inside windows like an application. People who are very much used to windows for their day to day usage are a bit hesitant installing Linux on their machine.

The major advantage of windows over Linux is the fact that many of the application vendors choose their default platform as windows operating system. Although there are some vendors who make applications for both the platforms, still there is substantial difference in the amount of applications that are made for Linux than the applications made for windows.

how to use wkhtmltopdf to convert URL to PDF

convert html to pdf

wkhtmltopdf is a superb tool that can be used to convert a given url or local html page, to pdf format. This tool after installing can be embeded inside php code,inside shell script or any other scripting language.

there are several web based online tools available wherein you can specify the URL you need to convert to pdf as input and download the converted pdf file as output.

But those tools cannot be used while working in a console terminal, or is not a viable option when you need that functionality in a script.
wkhtml to pdf uses webkit engine and qt for converting html to pdf. this package is available for downloaded from googlecode.com
We tested this on an ubuntu machine...(works well with Red hat based machines also).
