Interesting Facts

I got placed today. Yesterday to be accurate. Only five hours and ten minutes have passed since my placement in Cognizant. But appears like it has been ages!



I wanted to share my interview experience with you. December 3 was announced long back as the first round date. My semester exams were over on November 24. And I relaxed for a couple of days. Then downloaded Vidathu Karuppu (Marma Desam) series and watched it. It was Saturday, November 28, 2009 and I was watching Vidathu Karuppu still. Sunday morning I woke up at 9. I planned to start with aptitude. I was trying out the cube sums and syllogism rules. And I watched the film departed once again(I have so far watched it 4 times). I have developed a strong liking towards that film! The day was over. I received a mail from the placement cell that there was a pre-placement talk from Cognizant on December 2(2:00-6:00 PM).

November 30, 2009

The next day I planned to go to hostel and prepare the technical stuff along with my classmate John(he is THE technical wizard of my class). Karthi was to join me as well. There was an interesting question in the model question paper that the placement cell had mailed us.

Why result is different for:

1)
int x=5;
int y;
y=++x + ++x + ++x;

2)
int x=5;
int y=++x + ++x + ++x;

In Type 1: Line 3 is treated as an expression, and based on the “Operator Precedence” the increment [ ++ ] operator takes precedence over summation [ + ] operator. Hence in the expression, the increment operation is done first, and then the summation operation is done, thus the output of the expression will be "24".

In Type 2: Line 2 is treated as an assignment statement, and is hence evaluated from left to right. Thus the value of ' y ' in this case will be "21".

We started by discussing this question. Then we moved to data structures. When we were half way through data structures me and Karthi left for lunch. And though we retuned to the hostel by 1:15 itself, it took us another one hour to start again. We finished Data Structures and then moved to Computer Networks. In CN we brushed up the concepts like OSI layer, Topology, and other important concepts from Wikipedia. Then we started Operating system by 6:00 and finished it by 7:30. I was feeling very tired. But was glad that I learnt lot of stuff that day.

December 1, 2009

Then on Tuesday, I was just maundering over Database management system concepts. And resumed with aptitude.

I was searching for different formula and successfully stumbled upon this,
If a cube has n sides and all sides are painted and if it is cut into (n*n*n) identical cubes, then it has:
cubes painted on 3 sides: 8 ((n-2) power 0)
cubes painted on 2 sides: 12 ((n-2) power 1)
cubes painted on 1 side: 6 ((n-2) power 2)
cubes painted on 0 sides: 1 ((n-2) power 3)

Probably this was the only new thing I learnt that day.

December 2, 2009

The next day, I spent on my projects. Browsed through the code of all my projects. Fine tuned my resume and left to college. I reached at 12:30 in my college. Had lunch and was chit-chatting with Karthikeyan, Sathish alias(Sathish alias is his nickname) and Arun. The pre-placement talk was scheduled to begin at 2 'O' clock. But it never really began until it was 3:15.

There was a video display about Cognizant and Mr. Vishnu, the Vice President and Head of Coimbatore division of Coimbatore gave his speech. He was speaking about Cognizant, their policies and stuff like that. I don't know if it was the acoustics of the hall or the time. I was feeling damn sleepy. But tried with all my concentration power to focus on what he was speaking. After he finished his speech, there was a Q and A session.

I felt that my college mates posed senseless questions. Few like...
1. Is there a rejection panel during interview?
2. What do you provide for recreation to your employees?
3. Do you really recruit non-technical(OMG!) students?
and many more....

But Mr. Vishnu answered them patiently! This man has amazing patience.

Then there was quiz session, where there were questions about Cognizant and people got caps when they answered it right. I knew the answers for couple of questions. But never bothered to stand up and give the answer. A munch or perk would have motivated me. A cap? no way! Finally there was a passion video, shown about Lance Armstrong, a gymnast and Kapil Dev.

It was 4:45 when the program was over. I reached home and started preparing the aptitude question from TIME book. I really prepared well. I prepared 4 books of TIME. It was really easy.

December 3, 2009

The next day morning, I woke up, brushed through different coding problems and binary problems. Went to Arumugam Student's centre(in my college), that's where the exam was scheduled.

I had to fill out a form(much similar to my resume, except for the projects section). It had questions like what would be the qualities of a good software engineer? How do you think you would be a good software professional? etc.,

The test began at 10:00 and ended at 11:10.

There were three sections. Quantitative aptitude(25), Verbal(25) and Logical reasoning(20).

The test was very easy and there was no single question from what I had prepared!

I performed well in the first and the last sections. English was always a doubt. It depended on the cut-off. I knew I can make it if the cut- off was around 10 to 12.

I heard from Arun that the cut-off was 7. I was quite confident of clearing the round but never admitted it to anyone!

The results were announced in mic. and it was quite a long wait before my name came up. It was second in panel 7. Panel 7... Ah! May be luck is in my side, I was born on 25, my lucky number is 7 and my panel number was 7. Coincidence may be...

I came home. Watched the highlights of Indian innings where Sehwag was rocking with a double century. And then slept off by 8:00 PM itself.

December 4, 2009

Woke up early in the morning(4:00 AM) and prepared Object oriented Programing, revised operating system, networks, data structures, database management system, checked out my project codes and modules, and finally studied C.

I left to college. Interview began at 10:10 for me.

My interviewer was a very warm person. He greeted me by standing up from his chair, walking towards me and giving a firm handshake. And the little nervousness I had while entering the hall had vanished completely. I was feeling very comfortable. He resembled my friend Vikram's(thenga) brother and was a left hander.

Interviewer: Introduce about yourself.
Me: I am Deepak. blah.... blah... I have developed 9 Projects.
Interviewer: We'll go into projects later. Tell me about your family, hobbies.
Me: I am the only son to my parents. Hobbies...hmmm... I write short stories, novels and poems.
Interviewer: Novels... Tamil?
Me: No sir, in English.
Interviewer: Oh! Have you published.
Me: Should search for a publisher. But one novel is ready for publish. Planning to publish soon.
Interivewer: Whats the name of the novel? What's it about?
Me: Spoke about Mystic Murder
Interviewer: Why Cognizant?
Me: Mainly due to a senior, a super senior actually... She gave very positive feedback about the work culture in Cognizant and her experiences. And ofcourse the growth curve that I saw in wikipedia and during the pre-placement talk. Where it moved from 1 billion to 2 billion and so on exponentially. Other than this the enormous customer-base that Cognizant has is amazing sir.
Interviewer: That's cool Deepak. What's the name of that senior?
Me: Sowmya.
Interviewer: Where does she work?
Me: Chennai.
(All the while the interviewer was looking at my resume. Thank God! He read through all my projects)
Interviewer: Seems like you have done a pay roll software.
Me: It started off as a pay roll software sir. But with 6 iterations and 6 versions it has now become more of a HR software.
Interviewer: HR?
Me: Employees joining, leaving, attendance management, Performance appraisal, salary, leave, rating of employee...
Interviewer: Oh! Thats great! What language did you choose for this application?
Me: VB .NET.
Interviewer: Ok! Then tell me the difference between VB.NET and VB.
Me: Spoke about CLR for sometime. Then suddenly realized that I needed to give the simple answer- VB---> Component oriented, VB.NET---->Object oriented. When I was about to start with exception handling....
Interviewer: Fine Deepak. What do you know in DBMS? Just write down in this sheet of paper, he said, handing a sheet of paper.
Me: Started with files, tables.
Interviewer: Fine Deepak. Just write two tables, fill it with data and show a primary key and foreign key in those tables.
I started explaining as I was filling.
Interviewer: You fill and explain Deepak. Meanwhile can I have a look into your file?

I understood that he wanted to occupy me with some work while he was skimming through my file.

I started explaining the tables I had written. He said, just tell me the primary key and foreign key. I replied.

Interviewer: Deepak. You say a good software professional must be innovative. Can you give an example where you have been innovative?
Me: Explained about my paper called Graphentication of passwords, where i had proposed Google earth to be the password!

Interviewer: What do you think about recession? How it affects student community?
Me: Spoke everything I knew about it from banks, companies to Anna university Counselling!
Interviewer: Deepak do you know what SDLC is?
Me: Yes sir, SDLC means Software Development Life Cycle Process.
Interviewer: What are the SDLC's you know?
Me: Waterfall, win-win spiral, Spiral, Iterative, Prototype
Interviewer: What SDLC do you think Microsoft would have used to develop .NET?
Me: Iterative.
Interviewer: Reason?
Me: Explained the logic behind versions, bugs, problem with sun and such stuff.
Interviewer: Would Microsoft be tempted to use waterfall model for .NET development?
Me: I don't think so. Waterfall model is not for complex projects. It is for simple projects.
Interviewer: Where can you use Waterfall model?
Me: I had developed a project called ICAL(of course with Karthi and Arun). Which is a simple internal mark calculator with a relative booster like if the top mark is 15 then it gets boosted to 20. 10 gets boosted to 15. In that, the requirements were 3:

1. Collection of the internal assessment marks
2. Calculation of the total internal marks
3. Relative boosting

And I submitted it to a Microsoft contest called S2B. Where I had to develop it using Waterfall model. And all the phases were finished at one stretch.

But when I was developing a project called Pearl (Payroll management and Employee ARchivaL), I collected requirements from a particular person, who had given me the requirements but resigned when I next went there. Then explained certain nuances of the project where I was unable to implement waterfall model and instead I had to work on Win-Win Spiral model and it wasn't a true Win-Win Spiral model either. I had to mix it with Prototype model. For faster delivery of the software.
Interviewer: You say that you are the only son to your parents. I cannot guarantee you a job in Coimbatore. Would you shift your base?
Me: Definitely sir. That wouldn't be a problem at all.
Interviewer: Ok Deepak. I am done with you. Do you know whether Sehwag scored a triple hundred?
Me: No sir. Yesterday evening he was 284 not out. That's all I know.
Interviewer: Thought you would be knowing it. Didn't your friends message you?
Me: I had my cell phone switched off sir. I hope Sehwag scores another triple hundred and adds a really expensive dish in the menu card of his hotel :-)
Interviewer smiled.
Interviewer: Do you have any question for me?
Me: Sir? If I join Cognizant? How would you like me to spend the next six months? Should I learn something? Like I have heard that Cognizant works on mainframe?
Interviewer: Just continue your routine activities and enjoy your college life. Eh Deepak! I have the form that you filled yesterday. That's enough for me. You can take back the resume you had given me. I will place it in your file. It was nice talking to you Deepak.
Me: I had a very pleasant experience too sir.

After a firm handshake I started to walk back. I turned back and asked him.

Me:May I know your good name sir?
Interviewer: Shyam.
Me: Thank you sir.

My interviewer was the kind of dream interviewer I could ever imagine off. He was very friendly always smiling at me making me very comfortable.

I left the hall. I was confident of getting placed except for the one incident of him returning my resume. It was sowing some doubts in my mind.

Interview was finished in 22 minutes for me. I came out at 10:32 and nearly after a nine hour wait, I heard that I was selected.

My friends Karthikeyan and Johnson were selected too.

Narrator: Everywhere I travel, tiny life. Single-serving sugar, single-serving cream, single pat of butter. The microwave Cordon Bleu hobby kit. Shampoo-conditioner combos, sample-packaged mouthwash, tiny bars of soap. The people I meet on each flight? They're single-serving friends.

Narrator: I'll tell you: we'll split up the week, okay? You take lymphoma, and tuberculosis...
Marla Singer: You take tuberculosis. My smoking doesn't go over at all.
Narrator: Okay, good, fine. Testicular cancer should be no contest, I think.
Marla Singer: Well, technically, I have more of a right to be there than you. You still have your balls.
Narrator: You're kidding.

[Poem on Narrator's computer]
Narrator: Worker bees can leave. Even drones can fly away. The Queen is their slave.

Skin Deep

Dr Westford: A scorpion who couldn't swim asked the frog to carry him across the river on his back. The frog said, "Do you think I'm crazy? Halfway across the river, you'll sting me and I'll drown." "That's not reasonable," said the scorpion. "If I sting you and you drown, I'll drown too." Frog thought about it, he said, "Climb on." Halfway across the river, the scorpion stung the frog, and as the frog was drowning, he said to the scorpion, "But now you'll drown too." The scorpion said, "Yes. I know." "That's not reasonable," said the frog, and the scorpion replied, "Reason has nothing to do with it. I'm a scorpion. It's my character."
Zach: "What the fuck does that mean?"

Angels and Demons

Camerlengo Patrick McKenna: Do you believe in God, sir?
Robert Langdon: Father, I simply believe that religion...
Camerlengo Patrick McKenna: I did not ask if you believe what man says about God. I asked if you believe in God.
Robert Langdon: I'm an academic. My mind tells me I will never understand God.
Camerlengo Patrick McKenna: And your heart?
Robert Langdon: Tells me I'm not meant to. Faith is a gift that I have yet to receive.

The Davinci Code

Robert Langdon: Why is it divine or human? Can't human be divine?

If your name is not there in the list then don't get disappointed. The inner satisfaction that you get after completing any version of Klueless is unparalleled. So, start playing!!!

This is what the klueless team says in their hall of fame. Infact, I was very happy too, though I didn't make it to the klueless 4 Hall of fame, last year, finishing it gave me an inner satisfaction. But this year, I wanted to make an entry into hall of fame. I was often googling about klueless 5 from August. Then in October, the klueless guys started the count down for Klueless 5.

Klueless 5 started on November 5,2009 9:00:00 AM IST. I had my semester exam(UID) on November 6 :(

Knowing that I was playing Klueless 5 aka K5 took me past that level.

There was a picture from which I was slowly removing the tangles, Arun came up with the solution.

There was a word Will. So, Arun said that it must denote William Shakespeare and we were exploring on The Tempest story, about Prospero and the Angel. It was all waste of time. My intuition said we were wrong. And I remembered reading an Island story during my childhood. And the solution became evident.

Aah! This was the level which took lot of our time. Karthikeyan joined us here. There were numerous options. Arun came up with a way of reading between the images. Then it seems he found the wiki page which contained the answer. But he didn't try the answer :-(. I was taking a little break at that time. When I came back, Arun had left due to power shutdown in his home. I found the wiki page and the solution too.

It was a very simple level. Needed just a couple of minutes. Just checked out on the ROFL part.

There was a button, click me. But when I tried to click it, it moved. So I tried using tab. A message box appeared saying "You cheated! Use the mouse." I checked the source code. The Klueless team had played prank on us. In the source code, they moved the button on mouse over. So it is impossible to click the button with the mouse. I ignored it and concentrated on the picture. Oh! There was a box. I thought may be Pandora's box? Then I googled the source code. Answer was available immediately!

Since I used to make lot of mistakes while typing messages in my mobile. Like, "Has the cup come?" instead of "Has the bus come?", this level was a cakewalk for me. The answer was spot on! The level's name was Texting on the sly! It was apt.

Leytonstone is a place which I knew for only one thing. And that was the answer too!

Here too the klueless team had played a prank. The :P from horse was well thought out. But it wasn't that tough.

I was searching about the passage everywhere. But couldn't find anything :( I was discussing in the blog of klueless 5 for the first time. Then suddenly I remembered that this was lvl 10 and not level 10! There was the solution!

Level 10. Didn't seem to leave me. There was a detective story over there. It was 2:00 PM. So I went for lunch. Coming back I could see Karthikeyan online. He was good in detective stories. He gave me the idea of who it could be and since it was an extension of the last lvl,solving this level was not tough anymore.

It was very simple. The poem in that level meant an incident, reading Digital Fortress really helped me. And what can one ask more than the picture present there.

This was a level that was very hard for me. I am not a master of vocabulary! There was an India-Australia match running and the Indian bowlers were thrashed to all parts of the ground :-(. And it was really tough for me because I was watching match, I could not focus my attention completely to klueless. I was trying strange methods, I went to the extent of trying all the words ending with 'ly' :-O. Thats when a guy called Aditya, sent me friend request in yahoo. I must thank him for telling me the answer to be an adjective!

It was 5:30 PM. Arun and Karthi were sending message to me, close Klueless and goto study, which . Last year I nearly flunked(somehow escaped) in a subject called Theory of Computation because of playing Klueless 4 without studying! This year was no exception. I had my semester exam(UID) and I was focussed more on klueless 5! Then I had to go out. I returned home and the Indian innings had began. Sehwag was rocking as usual and Tendulkar was playing sedately. But after crossing 17000 runs, Sachin played a pull shot. When Sachin plays pull shots, he is in mode-ATTACK. I love to watch Sachin when he is playing the pull shots. He is one of the best. But he doesn't play them often :(. Sachin played one of his best knocks, 175, while chasing was a great innings. But he couldn't finish off the match which he did so well in the CB series final! He played a crazy shot and got out. Match was lost by just 3 runs. It was Jadeja who surprisingly gets run out because he runs like a mad hare when his partner shouts "NO!NO!NO!" who lost the match single handedly! Pathan would have handled pressure situation well. It was 11:00 PM when the presentation of the match was over.

OMG! I hadn't studied a word for my exam :-(

Slept at once and woke up at 3:30 AM next morning. Was studying, till 9:59 AM, with my pals Arun and Karthi. Exam began at 10:00 AM lol :) But exam was quite easy. So it was not a problem. After this exam on Novemeber 6. I had one week leave for my next exam. I knew I could pull klueless 5! Came back to home had lunch and started playing klueless once again!

It was 3:00 PM...

Ah! You know how I solved the level, i saw an image map. Saved the web page in my system. Opened it in Microsoft expression web, then found the exact location of the image map. Clicked it to find a superb clue which directed me towards the answer! I don't watch Jeff Dunham shows and it actually cost me some time.

I knew the answer immediately after reading the word verbose. I wasted time on typing the answer in the wrong place. Then remembered how I chat. It helped me solve this level. Karthi was with me in this level. But he had some problem with his net connection. Arun called me up and we were discussing on this!

It was nearly 4 in the evening. I loved this level. I would rate it as my most favorite level in klueless 5 for the sheer brilliance of the level. I was blind over what the solution could possibly be. Then when I saw what the dice meant, I was blind-folded. One clue that really helped me was from the forum. It said, 'Find the rhyme!'

It was 6:00 PM. Arun and Karthi joined me. But now my net had some problems. Found that it was related to a comic. And by the time the wiki page loaded for me, they had found the answer.

Oh! This level was brilliant. We thought too much actually because of the clues in the blog stating that we needed to be tekhie buff and movie buff. It was actually misleading. Then I took a break from those guys and went to watch tv. Resumed klueless at 11:30 PM. And I was able to solve it immediately. Taking break between the levels definitely help. After all, I am playing Klueless and not Clueless!

It didn't take more than 30 seconds. Boom! Playing games do help!

There was a poem in that level. And I immediately decoded what it meant. After that it was just simple googling.

Change the perspective or expand your horizon. The level says.I tried lot of things read lot about a game called BINGO. Which was not necessary at all. It was November 7, 1:00 AM. I thought of taking a break from klueless and was watching Lord of the Rings. it was 4:00 AM in the morning. So slept off.

When I woke up, I found the time to be 2:00 PM. Oh! I had slept for 10 hours while playing klueless. The biggest crime in my life... lol :).

I decoded the poem. But I was making mistake on a line reading them as two numbers instead of a single number.

Aditya pointed out my mistake. Then it was simple march to the answer.

The powerpuff girl was easy. But the other part, I would not have solved if Aditya did not tell me about recession.

There was power shut down and my UPS had drained out. So I forced to shut down my computer :(

I again slept off. From 4:15 to 6:30 PM!

Woke up. Then this time I had to connect the dots and find company! It was easy!

I was thinking on a method to solve it. Aditya said, he can't help me because he himself didn't know the method. Some guy had posted a spoiler which made Aditya''s life really easy. But the moderators had deleted it! Then having so many doors reminded me of a Tamil film, 'Kaasey thaan kadavulada' Manorama uses a method to enter into her safety vault! I tried that method and it actually worked out :)

It was 8:00 PM. Arun joined me. He actually thought too much. Found that in medieval period, S, N etc., were roman numerals. He left for dinner and never turned up. (For the rest of Klueless :-(...Sob...Sob...). I too left, was watching tv and resumed klueless at 10:30 PM.

I read about Cleopatra, how she died, all that coupled with the rules of klueless 5 helped me to solve this level. But I was having a small problem. If I was in north pole, how could I travel north. I posted in the blog and got a reply that, the journey from start should carry on. And I was able to solve this level. I liked this level!

This could be compared with the 15th level. It was too good too! But being a Computer Science student, I was able to solve the RGB stuff in real quick time. Writing down the colors in a sheet of paper really helped me ;-)

Here again, I was thinking too much. Thats when Hema had posted her email-id on the page. I sent her request in gtalk. And she told I should think less. I understood what is to be done. All I can say is it was an A-1 level!

Posting anything on how I solved would be a spoiler. But all I can say is, I solved it really fast because I had been watching lot of movies for the past two years!

It was Novemeber 8 12:30 AM. Hema left. I lost my net connection. Watched Angels and Demons once again. It was 3:00 AM.

Found the song required and used photoshop. I didn't spot any difference. Then I remembered the rules page once again. It helped me to solve this level.

I knew what the image meant. Wikipedia provided the solution!

Ah! I focussed on one single line. It was the last line. Then connected it with clue. Tried trial and error method to connect to the answer :)

It was 7:00 AM in the morning. I had breakfast. It was raining and I was enjoying the rain. India Australia Match started at 8:30 AM :O. And wickets were falling like 9 pins. I knew no miracle would happen with the stupid Jadeja batting! Surprisingly Jadeja made a fifty. And Praveen saved the day with a good knock (ofcourse with lot of luck). I resumed klueless 5 at 11:30 AM. I interpreted the notes. I fought hard for 3 hours in interpreting and then left out. The rain and winds had made banana plant in my backyard fall. I never knew banana plants were so so heavy :-O. It was 5:30 PM when I resumed after lunch, rest,tv. Hema joined me at 6:00 PM. She had no clue on 31 what so ever. She gave me a different set of notes. Thats when I realized, I could have read the notes wrong. I read again slowly. Found that both our interpretations were wrong. After getting the right notes, it was just 2 mins to solve the remaining. Because I had spent lot of time already on devising it!

The Greek sculptor was the obvious one!

Hmmm. I liked this level and its connection with level 32. A number helped me solving this. But its simple even if random tries are made from the source code hints!

It was 8:30 PM and I went for dinner, returned by 9:30 PM. Hema had marched to 36th level, in that one hour! 34 was easy once I found the bearded man and MIT was a reasonable clue.

It was 10:00 PM my net connection was totally out! ADSL light did not glow at all :(

I had an alarm for every one hour and slept off.

It was November 9. Till 6:00 AM in the morning, the net did not work. There were offline messages from Hema, like 'Are you there?' 'Damn with your internet connection!'

The net connection was highly unstable. The first thing I did was checking the hall of fame. I had a heart attack when I saw the Hall of fame. 90 people had finished and Hema was there too! I was cursing BSNL, my ISP.

I figured out what was meant of the tables. Then it was really easy. But I should have remembered that people call me Deepak and not Deepak Senthilkumar. Somehow managed to solve the level. Wiki really helped me.

Ah! this was the level for which I troubled the moderators too much. I must really thank klueklutz for patiently replying to me! I thought too much and connected Rafael Nadal to the level when even Roger Federer was not needed :-( But its a simple level of googling the right stuff.

Net connection was still unstable. I got as much information as possible in the short span of time when my net works.

It was 1:00 PM.

When I saw tintin in this level, I remembered a level and figured out on what had to be done. I was making a simple mistake with my logic which was spot on! Klueklutz and Curses, the moderators of Klueless 5 clarified me and suggested a break. I had lunch, returned by 2:00 PM and found the solution immediately!

And only the final frontier had to be conquered!

I was feeling exhausted because of my damn internet connection and working alone. Was trying some fishing from the forum & relaxing, Curses detected it. He suggested me to play the game than hanging in the forum. I started the last level and figured out a way to solve the final level. It was pretty odd but it worked out. The final level belongs to the Lord! It was 4:00 PM and Klueless 5 was conquered.

Actually it was finished in 4.4 days. But 0.6 of that was dedicated towards my semster exam and the cricket match. So 3.8 days ;-)

And on my quest of reaching Hall of fame, yes! I did make it... 115 is my position. Could have reached a far better position had it not been BSNL's fist of fury on me.

Had a lot of trouble posting this here too :-(

It did help me actually on not working with Arun and Karthikeyan. Because, I had a unidirectional thought, which helped me actually.

Had a great time playing it! Hope you have a great time too!

One summer day in France in 1826, Joseph Niepce took the world's first photograph. It's a photo of some farm buildings and the sky. It took an exposure time of 8 hours. Voila! It had to feel pretty incredible, like magic.

No one's exactly sure how he did this or what chemicals were used. All that's known for sure is that the photo is on an 8"x 6.5" pewter plate. It's so faint it has to be tilted in order for the light to catch it just right, to see it. The Getty Museum in California did two weeks of tests in 2003 in a joint project involving the Rochester Institute of Technology and France's Centre de Recherches sur la Conservation des Documents Graphiques (try saying thatthree times fast). Then it went back on display at the University of Texas in a new air tight case, where it's been on display since 1964. I'm not sure why we have it and the French don't, but "hah".

The current theory about how the photograph was taken is that Niepce coated the pewter plate with bitumen, a petroleum derivative sensitive to light. After it spent those 8 hours hardening, he washed the plate with a mixture of oil of lavender and white petroleum. This dissolved the portions of the bitumen that didn't 'see' direct light, so didn't harden. Pretty damn clever. Niepce called his work a "heliograph," in a tribute to the power of the sun.

Article Source:World’s First Photo. Really?!!!!

A software bug is the common term used to describe an error, flaw, mistake, failure, or fault in a computer program or system that produces an incorrect or unexpected result, or causes it to behave in unintended ways. Most bugs arise from mistakes and errors made by people in either a program's source code or its design, and a few are caused by compilers producing incorrect code. A program that contains a large number of bugs, and/or bugs that seriously interfere with its functionality, is said to be buggy.

Common types of computer bugs

Conceptual error (code is syntactically correct, but the programmer or designer intended it to do something else)

Maths bugs

Syntax bugs

Use of the wrong operator, such as performing assignment instead of equality test. In simple cases often warned by the compiler; in many languages, deliberately guarded against by language syntax

Resource bugs

How about some bugs for snacks?
