Windows 7 audio devices not installed problem

This is a problem i faced with my Windows 7 where suddenly out of no where my audio stoppped playing and it showed “no audio devices installed” .

I tried many things and finally i was able to get it back. U can go for downloading Audio drivers and installing it or by going for recovery like System Restore but it did’nt helped me.

If you have a Laptop then I would recommend this one.

1. Open your control panel and then go to Hardware and Sound.
2. Then go for Device Manager and Open it.
3.  Then scroll down to Sound Video and Game Controller. Right Click on it and further click on ” Scan for Hardware Changes” this will correct your problem.

If  you have a PC then in the Device Manager ” Sound Video and Game Controller” usually does’nt shows.For this kind of problem their is another solutions.

1. Reboot your PC and go for System Setup by pressing F12 during boot process.
2. Then reset all settings to “Load Default Settings” or by pressing F9. Do these for all settings except Booting menu let it be the same.
3. Then Restart your PC audio will start working.

Facebook Video Calling Plugin

Finally Facebook launches its video calling facility with its collaboration with skype.

Its Installation is very simple.

1.First go for www.facebook.com/videocalling (make sure the browser you are using is an updated one otherwise it will not support)

2. Click on  “Get Started”

3. After that you will see a small camera icon on ur small chat window (if not then refresh the window) . The person who is Online just click on cam icon, well this is not it.

4. Then after few moments automatically a download starts for  “FacebookVideoCallSetup_v1.2.199.0.exe ” which is around 500 KB of size.

5. Finally when you install it, its autmatically starts downloading and installation of the actual “Facebook Video Chat Plug-In” directly. You don’t have to do anything.

Once the installation finishes u r ready to go.. i used it any its pretty impressive in Slow Connections also. I connected my mobile to lappy (which is hell slow) but i have to tell that picture with sound quality was really amazing which is not possible in Gmail videochat plugin.

Enjoy..

My Placement @ Infosys

In IIT Kgp placement season starts from December 1st  and continues till the companies are interested in what they call us “Cream of India”. For us (M.Tech ECE) it started a bit early ie. 30th November evening i was giving the written exam for Texas Instruments(TI). For us our 3rd sem final exams were delayed till 28th NOV enough to make a permanent unrepairable dent on our Placement dreams . Not having a clear idea of how exactly should i prepare myself, days and companies came and went.

But i had an interesting start to my placement season. DEC 2nd was the day when company named Brocade Comm.  called us for written test,  a good networking company was a dream but without preparation it was close to nightmares.

5.35am : I was awake..
5.45am: I kicked Abhishek to wake him up and reminded him about our first dream company written test starting at 6am.
6.05am: Impeccably dressed up in White shirt & Black pant, we reach V1(where test was held)… (without toothbrush or other chores.)
6.06am: All rest 500-600 students looking at us… we were the only ones ‘impeccably’ dressed! Others were in casuals/ sweaters. Felt embarassing!
6.30am-7.30am: The test. 3 sections- Apti, OS concept & C-prog. Little difficult. Attempted 35/50 questions. And then came back to room.
12 noon: waiting for result was too painful so i thought it would be better to have my own sweet little nap.
12.10pm: This time it was Abhishek’s turn to kick my ass. Results out! Abhishek, myself, Jacob & Prince selected for Tech interviews starting 12.15pm. Adding to the anxiety i got a call from Placement office that i was the first one to be interviewed. <HELL>
12.20pm: Wiping all the sleep from eyes, went inside the interview room.
1.05 pm: unlike others i had 2 different interviews.  Interview over.
8.00 pm: Interview results out. Only Prince selected.

Total 30 students were shortlisted for interview and finally 7 got selected.  In the first week when with good jobs and not forgetting to mention high packages came to our campus. Some of them were..

Brocade Comm, Intel, Alcatel Lucent, Goldman Sachs, Analog Devices, Mentor Graphics, Qualcomm,nVidia, Cisc0, Synopsys, Oracle, Ericsson, HP, Tejas Instrument and many more…

From 2nd Dec till 10th Dec i tried and was rejected in all of them.. reason being unable to qualify written tests, heavy competition( comeon  its IIT), big companies with small requirements, disaster interviews ( Oracle lasted for 10 mins   ).

But with time preparation improved and finally came the most hectic day of my placement season ie. 10th Dec. From morning 7 am we had written test for HP which started at 10 and performance was satisfactory. Again not qualified, but still i waited their and helped others as a moral booster for those who got through. afternoon i came back to  my room and the news was out that Infosys is coming for the placements same evening.

Preparation was ok but still did’nt wanted to loose again so went thru everything as fast as i could. we were called at 8pm. Reached Vikramshila and it was a mela kind of a scenario, It seemed that everyone was eligible for appearing. it was kind of a superslow process where we took our seats at 10pm and Infy guys finally came at 11:30pm, the wait was again painful. after that again they started a long process of filling up the form. its was around 00:15 morning when we had question papers in our hand and we started with the test. it went well and i submitted paper in a  positive frame of mind by 2 am morning.  but again adding to the overloaded tiredness came a colossal news from hell. Tejas Network guys were there wanting to take their written test from 2:30 in the morning ( r u serious ) . But still i went for it, i could’nt afford to loose a company just because of a silly reason of me dying due to tiredness.

Then i gave a tough really tough written exam that sucked everything out me, it ended about 4:30 in the morning. i reached my room by 5 and did’nt slept untill 6 checking all the notices and mails. then i don’t know when & what happened i got a knock at my door at  8am “abe saale jab tera written nikal hai tu ghoda bech k soya rehta hai” it was abhishek. could’nt abuse him for waking me up because he came with a good news, bas news was that i had to reach Takshashila by 8:30. Abhishek was already placed in Mentor Graphics (YO Abhi..) so this time it was his turn to help me out with my pre interview preparations. i would like to share with u all an incident when abhishek’s second interview call came from Mentor Graphics,  he forgot his updated CV(he has the habbit of getting into trouble when u least expect it) and called me for it. (i was asleeping ). then out of nowhere in just 10 mins i got a print out of his CV,  took someone’s cycle and raced t0 takshashila in my dirty boxer and Tshirt (high priority package was delivered with all the embarrassment in the world ).

So coming back to my placement, i waited for about half hour for my interview turn.. then finally moment of truth came. Question they askedwere technical as well as HR, my Mtech project was the main topic of discussion for my interview and some C question here and their. Some hardware question were also asked which i did’nt answer completely and one or two from social activities . Finally i came out confused and yet trying to figure out how eveything went. Interviewers asked me to wait outside.. so i was doing so, then finally HR(he was also from my hometown jamshedpur, sounds like an advantage ) called me and directly gave me the good news that i was selected. Job profile given to me was of  Technology Analyst and finally i got my most preferred job location Bangalore.

Shadow Dance

Direct dil se…

i look back into time and see howz my life has been its has been pretty satisfying and i never dissapointed myself.. still there are some voids to be filled and some wishes to come true.

i have seen people worrying of how it was and how it is. the fact is that whatever it was is your past and whatever it is is going to become ur past pretty soon. most of the times past are painful wether they are good or bad.. past is like a jail which steals your freedom of thinking something new and fresh. when we are alone in our free time we think about our past some dream about how it could have been. i myself has wasted a lot of time in that. and believe me it adds to the pain.

just think if instead of all this if we start thinking some thing new fresh something we always wanted to do. just write your wishlist(must be realistic) and believe you can achive them pursue them . whatever energy you were wasting in your past invest them in present to shape your future.. look at elder people around you talk to them ask them what they miss most in their life now and whatever answer you’ll get will be related to time. i have always heard them saying i never got time for myself otherwise things could have been different .. but we have our life in front of us ..  people remember its never too late. do something satisfying to yourself achive something .. do not survive this world create  your own world.

my library duty..

during this summer vacation i got a unique oppurtunity of doing  library duty.. nisarg saw this notice on dc  where interested students can get around 100 bugs per hr. this one seemed to be a good oppurtunity so nisarg, abhishek and I decided to apply  for it, as always …finally i was the only one who applied. i got 4 days of 2 hr slot each from 10 pm-12 midnight .i was ready for it and had a good $$ reason too.

i did’nt knew what actually i had to do in it and i never tried to think upon it ,well how much difficult it could get  its just a matter of 8 hrs. 1st day i went there and asked the security about it . first he took my name roll and signature in 3 different registers which was pretty irritating and then finally gave me an answer that just go and sit somewhere. i was happy to know that the job was just to sit and relax otherwise i had some wild guesses of me carrying loads of books from hall 1 to hall 6 .

i usually sit in the journal section where we have good air conditioning and nice comfortable chairs to sleep. i quickly went there and  mind it i do had my notebook with me to study. i heard someone saying that we had to switch off lights of each hall while leaving as the part of our job, from 10-11:30 i just waited with my concentration more on my watch rather on my notebook. as the clock hit 11:30 i went to hall no 4 and started switching off the lights at first it was fun trying  3 to4 swtiches at once but it went boring when i realised there were too many switches. finally after around some 200 switches this marathon came to an end. while i came to the ground floor the person incharge asked me wether i did the job or not i very proudly said yes “hall 4 poora band kar diya ” but he made some akward face and replied  ”aur annex building band kiya na ” ..

shit i said to myself annex building is like 4 floors of journal section where thousands of journals are kept like a safe. no body usually goes to that area. i was a little annoyed but was ok with me  n i said to myself ” paise bhi to de rahe hain chalo kar dete hain ”  , i started with ground floor it was haunting and silent all around . not a single soul was there to accompany me instead there were thousand of books may be lakh of them ,some like not touched from decades. i slowly went to every corner and swtiched off  lights and fans the more they went off more silent and darker things became. these safes were long and there was little spacing which made things difficult for me. it seemed as if i was inside a horror movie where a suspense scene was about to be broken by a ghost standing next corner.

finally ground floor was over but 3 more were there to go .. in my orientation day i was told that IIT KGP library had one of  the asia’s biggest jounal collection . i practically visited every corner of  its massiveness. finally about midnite i completed my job as i swiftly gained speed after some experience with switches .  while coming out to the enterence i saw the whole library in darkness as if all those books were left asleep. i was the last one coming out while hall 1 was totaly under darkness.

i left the the library prasing myself of doing a daring job and saying to myself “200 kamana utna aasaan bhi nahi tha ” . at the end it felt nice that first time in my life i physically earned something. i added a new and very challenging experience to my life..

I think i m lucky to have an xtra 2 yrs as my college life..

After completion of my Engineering i m very happy to say that all of my b tech frnds are setteled now. As far i know me and my close frnd Dhiraj are the only two guys doing Masters. Its very nostalgic to see all those close to me in different parts of India . Frankly speaking i don’t even know when am i going to meet them again.

Whenever i get time i share my feelings with them. Now they are working they have a scheduled life they have people above them who are trained to get work out of them. They must have realised it completely by now that rest of there life will be like this only. They have accepted it whether they like it or not. The urge to settle and be self dependent is much stronger than chasing any other desire or areas of interest.  As they say starting a software career is very challenging at the same time very interactive too. They say they get their job and they have do it their is always someone standing over your head explaining what basically deadline means(BOSS) .  Sometimes they enjoy their work sometime they just wait for the day to pass( basically mixed emotions).

And then i m here in IIT KGP doing my M tech in Embedded systems . I have seen people complaining about their job about their boss about their location ect ect, after listening to all this only one thing comes into my mind, i feel lucky to be here still enjoying my college life. I still have a free mind now ready to accept or decline things according to my choice. On the other hand this awesoome place makes everything happening and dynamic . When i started this course i missed my previous life and never thought of welcoming the new one. Now i realise that what all of my friends miss today is still with me. i have completed a year and have one in my hand. I want to make most of this 1 year.

My M.Tech Final Year Project..

Its been a long time after my last post..  finally i got a good and decent ( ) Topic to write on. It started long ( 4 months) ago when there was all the rush and axiety for selecting our Final  project. Loads of discussion and lots of options were there for us (24 students 25 projects). But from the word go i wanted to do something on networking.  My one and only choice was  Wireless Sensor Networks . It seemed interesting but had to do some research on it.  so i started with research paper dated 2005(introduction types) and read it to some extent. i liked it and read2-3 more(only introduction).now after doing this and talking about it everyday i could’nt think of anything else. But things are never that easy for me because just adjacent to my room’s balcony is Abhishek’s ( www.abhitak.wordpress.com ) balcony. everyday we had discussions from our balcony and all my academic suggestions came from that knowledge source only ( Nisarg is the Root of all this ) . this is what me and abhishek call it as “The Balcony Effect” . So due to all radiation and paranormal suggestion that came from that balcony changed my mind a little bit. We discussed about the pros and cons of a Sponsored Project( project given by some other company or organisations) and then generated a strong thought about taking that. I always want some thing big and impressive( as usual) for myself. so met the related prof. and gave that option as my first option and second one ofcourse ‘WSN’. now the wait started and after 1 month or so allocation were out. between this period abhishek and me did all the calculation and all types of permutation and combination for my chances of getting it  ( abhishek was quite sure of getting it 8.8 gpa ) . But what we saw was a disaster for abhishek  and much of a surprise for me. He did’nt get that sponsored project and i got Wireless sensor networks. how amazing was this “i had a ready mindset for sponsered project and me and abhishek discussed about how we will go through the yr ( coz calculation said i can get it) with it. This was because of a strange algorithm used by our prof called “Round Robin Algorithm” (plz google for understanding what it is) . Abhishek as he is did some thinking and said “bhendi isi mein jane k mere ko” . thats what i m talking about “i said”. but what about me what should i do now ?? now i had to resume everything and start all over again.  i lked something i had it but i preassumed something and i did’nt get it. should i fight for it or should i be happy with what i have. Now the balcony effect was a little low ahishek said to me that u  have a choice of selecting between good one and the better one. but conclusion beacame much clear after sometime ” i went for what i had becoz i liked it. now i have started my project on WSN precisely called as ” Fault Tolerance in Heterogeneous Wireless Sensor Network” and i love it.
