The dilemma of choice : 8051 or AVR?

When someone starts learning microcontroller, a simple question arises. 8051 or AVR?
Which is better ?
1>Well, at our level, whatever you can imagine, can be done by 8051 and AVR. The thing is, how far you can think and actually implement it.
2>Secondly, someone might say 8051 is very old and obsolete. Old is gold is true in case of 8051. 8051 is used widely in industries because of very much robust architecture and reliable operation which is not the case of AVR. Why? Is AVR bad? no, it’s new.
3>On board ADC of AVR makes it better? Nopes! because there are 8051 variants which has on board peripherals same as AVR and PIC has. Atmel itself makes USB 8051!
4>It is recommended to learn 8051 first because everything about 8051 is pretty simple.Hardware, software,programmer etc. So, one can focus on learning rather than debugging of unnecessary things. Plus, 8051 is cheaper but that is not the major point.
5>Once you learn 8051, you can go for anything you want. Important thing is not to learn microcontroller but to learn the process of learning a microcontroller.
6>”My neighbor has a merc so I must have it.Similarly, my friend is learning AVR so I must.” Stop there fella. Your friend might be doing it before you even thought of thinking about microcontroller.
7>It is not that one can’t start with AVR, but you know, 8051 is easy peasy which will keep your interest alive in this field.
8> DO NOT EVER START WITH ARDUINO. Yes, it’s a killer and suicidal for engineering student community.

This topic is open for discussion.

An interview with myself

Rikil: Hi, thanks for giving your invaluable time.

Me: Baah! ok ok. Let’s not waste time and continue with the thing.

Rikil: Oh sorry sir, ok first question. Who are you?

Me: I am an Electronics engineer with little knowledge in it.

Rikil: Oh little? haha we thought it as zero!

Me: I am not comfortable with this interview.Can I go?

Rikil: Oh so so sorry! Ok second question. Sir, what are you doing after your graduation?

Me: Ok.I was placed,let’s not laugh, in TCS and IBM. But I don’t have any aptitude in IT jobs as such. So I decided to stay in Surat. I got job at Lexus Softmac because I’ve completed my internship over there. There are some nice people out there who taught me a lot.

Rikil: Oh that is nice. So, can you just tell us about Lexus Softmac?

Me: Lexus SoftMac is a company engaged in making Diamond manufacturing machines. They have global presence in this field. Even though they are smaller then their competitor, their technology is better then any one else. Innovation with quality is their USP.

Rikil: Nice to see a Indian company doing such great thing. What was your role out there?

Me: Haha, I was involved in almost all the departments. But my major task was to handle the manufacturing of special thing which I can’t mention here.

Rikil: Oh,was it secret?

Me; Yup,it is. Only 2 companies have this technology. Lexus is 3rd. Even Indian Military needs this technology.

Rikil: Yay, it must exciting,right?

Me: Yeah, but it was routine for us.

Rikil: Ok ok. Next question.Why did you left Lexus?

Me: Surprising thing it was, for all. There was no problem at Lexus but the thing is, I wanted do something on my own.My interest was in embedded system and electronics even though i have little knowledge in it.

Rikil: Little? Haha!

Me: Why the hell…ok thats it I am going.

Rikil: No no please sir.I will loose my job if don’t complete this.

Me: Than behave yourself.

Rikil: Yes sir, sorry sir. So what are you doing right now?

Me: I have founded a company names Robosis. It is involved in field of Robotics,Automation and electronics. We give consultancy,design and manufacturing services. Also robotics training is also one of the major area of interest. We are in process of product development so pretty soon, you will hear about it.

Rikil; Awesome! What is the meaning of Robosis?

Me:Haha, its just wordplay of genesis merged with Robot. So ROBOSIS!

Rikil:You’ve got cool logo.

Me: Yup,I designed it.

Rikil: Great. So, sir We thank you again for your time. We wish you best of luck for future.,

Me: Thank you.

Rikil: Sir one, off the record question if you don’t mind.

Me: Yeah,sure.

Rikil: Is it really little or is it zero?

Me: Tari ma**, *%$&#*

Install multimedia codecs in Ubuntu

Due to copyright problems ubuntu doesn’t have MP3 plug-in in built.We need to install restricted drivers manually.Also some other basic things like Java,Flash Player and other plug-ins are needed to be installed.Now,it is surely a cumbersome process to install each of them manually.So,after ubuntu provides a package for such restricted drivers.You just need to download them and you are done!

Type: sudo apt-get install ubuntu-restricted-extras

First it will download 87 MB of packages and will install them.installation takes while due to no. of libraries installed.Also it will install windows fonts.

We’re one but we’re not the same

Did I ask too much? More than a lot
You gave me nothing
Now it’s all I got
We’re one But we’re not the same
Well we hurt each other
Then we do it again

One.A wonderful song by the great U2.I don’t know what was in writer’s(again the great Bono) mind when he wrote this song but it clearly shows there are people who can write something so powerful which can cut your heart in two and make you think about you and people around you.The most powerful line is “We’re one but we’re not the same”.I mean what the hell!All the theories of equality and secularism dies here.This is what we need to end all hustle.All grudges,which are based on race,religion,region,language and a lot many parameters.Just one thing.You keep your identity but respect others’ too.So simple.There is no room for any kind of quarrel ¬†or fight.But when people starts bragging about which is not also a real problem until it includes “we are better than them”. Good lord give¬†merciful heart to them!

Hope this song reaches in every heart and it can end all the riots and world can be a good place  to live.
