Scripting languages

Scripting languages:
  • Which automate tasks
  • Usually interpreter is needed.
  • Created with using basic primitives(meaning given below).
  • Rather than their use for creating applications, they are used to control the applications. They can be in different language than language of source code of application.
  • Eg. Shell Scripting languages manipulate with the files,directories which were not created using scripts, so they are actually beyond the domain of scripts. Basically they just automate stuff.
Difference between interpreter and compiler:

Interpreter
Compiler
Analyzes one line at a timeAll program at once
Directly converts into binary code, which is executable by itself that is independentlyIt converts in object code. Then linker is expected to convert into executable code.
Memory requirements is lessMemory requirements is more
Takes single line, compiles it, executes it, then only moves to next lineFirst whole program compiled, then execution
No object code is created, so every time same thing
Once compiled and linked, can only run the program.

It basically needs dynamic and static libraries to run the code


What are primitives in computing?   The basic sub-elements upon which so-called developers develop a complex code.

 In this post I will try to explain as many scripting languages as I learn.
For now, following are the scripting languages I have learnt:
1. TCLSH

I will try to add more to the list as I learn.

What should you expect in an VLSI interview as a fresher

This post is for everybody who is or was ever interested in working in a electronics core industry, or developing a hardware system. Though my post will be on entering in VLSI industry, more specifically in Digital VLSI Systems. Well, to be honest it won't be easy. But then congratulations, most difficult tasks are the most rewarding, and I mean it not just in terms of money/salary, but in regards to a competent and challenging task as well. Well if you are one of the many who is preparing for an entry-level job in VLSI out of a Bachelor's or Master's degree, this post will definitely guide you on how you could keep your preparations more focused.The post is based on my and a few of my colleagues' experiences in VLSI interviews. You won't get a plethora of interview calls from the industries, so when you fetch one make sure you crack it. Having said that, there are many courses available, which can help you bridge the gap from your Fresher's status to an i

The struggle to enter VLSI industry is for real

   The best moment of your life is when you finally get to work on something you had hankered about, craved for, dreamed about. All the sacrifices you made by not attending those parties with your friends, all the weekends you toiled on with your work, all the head scratching moments you spent with the analytical problems you slogged on, become worth it, when you finally achieve your goal. Trust me, there is no better feeling. I was in a similar situation, and after all the hard work, I finally started my career in the VLSI industry. Well, you see so many experienced engineers in India working in the field of VLSI, though ever wondered how these folks might have got a kick-start towards their careers, then you would find this post relatable. Everybody out there is talking about the projects they participated in their career, years of experience in the field, though rarely people talk about the struggle they underwent towards their goal. In this post, I would be talking about my experi
