Am i a Dreamer????

Am i a dreamer???, as the title of this post asks, i came across this questions many times, but i eventually supressed that thought upon doing the things and converting my self into a do-er, rather than dreamer.

Few days back, i been to read an article in Times of India, a survey that dwells about the qualities of planner / do-er/ dreamer. According to the survey, a Planner is one who like to have everything in order and spend hours before making decision. A Doer is one who takes the things as they come into and go ahead. But a Dreamer is one who do more planning than doing. The dreamer is one who spent much of his time planning, rather to fail (or lag) at implementation, and a bit idealist and want things to be done perfectly.

But my conception of Dreamer is one who can think of an idea, and plan it for implementation (i mean, a perfect plan), and go ahead with it. A dreamer can only lead the world!. A goal is a dream with a deadline, according to the author, An idea without at least some element of absurdity is not worth further consideration. Small businesses don't grow bigger without a dreamer, planner, risk taker, and doer. Enterprenuer is one who is more a dreamer in addition who can plan, take risks and implement. Today world is renovating more with dreamers, so the start-up boom. Without Dreams, you can not set a goal, without goal, you cannot plan, without plan, you cannot control, and without control you cannot manage either yourself or others. So i continue dreaming...!

temp2.exe (irc.momma worm) - How i got to remove it successfully

temp2.exe and/or temp1.exe, both these two viruses irritated me for some time yesterday. While i was copying some files using flash drive, my machine got to threaten of this virus. Some anti viruses treated it as worm, though it harms seriously. Mainly it deteriorates the data flow. So its related to network security. I clearly came to evidence that temp2.exe and temp1.exe are running on my system and until i ended them, i cant be able to detach the removable devices. In addition, when i tried to open other windows partitions, they are opened as new window, even though i havnt used that option. I addition it adds autorun option in the context menu explorer.

When i digg into the details, i came to know much about the virus, how its working, and all. If we are copying from infected machine, this virus puts three files along with the data into the disk.
They are: copy.exe, host.exe and autorun.inf
autorun.inf file contains only two lines.

[autorun]
open=copy.exe

when we open the infected disk, autorun will invokes and virus starts acting by running the copy.exe file. It creates a dump of above three files in root directory of each partition and make a copy of copy.exe in system32 directory. Also a copy of temp1.exe and temp2.exe wlould be kept in system32. Along with it corrupts the xcopy.exe and svchost.exe files in system32.exe. It also kept registry entry.

Steps to remove the virus:
So to remove the virus one has to be careful. First off the system restore monitoring. Then delete the three-files from root directory of each partition. Also remove copy.exe, xcopy.exe, temp1.exe, temp2.exe and svchost.exe from system32 directory. And the remaining is deleting the entries in registry. So to do that search in the registry for each of the file entries and manually delete them. After that restart your machine. So u will be out of that little dragon. a old copy of svchost.exe and xcopy.exe will be written back into your machine.

To check whether the virus got cleared or not, by observing the file properties of these two files. They must indicate the company info as 'Microsoft Corporation...'. If they are not from microsoft corporation, and anything which are residing in system32 directory must be from microsoft, else u can suspect of a malicious entry. After successful removal of the virus, u can continue by checking the system restore monitoring.

Dynamic Memory Allocation in C, C++ - my strange experiences with gcc and g++

Yesterday i learnt few strange things about malloc() in C and new, delete operators in C++.
Compiler referred is gcc for C, and g++ for C++ programs.

First one:
int *a=malloc(sizeof(int) *0); //i am trying to allocate 0 bytes of memory and pointing that location with pointer a.
==> What should happen, Segmentation fault( run time error) , since allocating 0 bytes of memory is absurd and then referencing it through a pointer a is too wrong. It went through compilation and run perfectly on 'dereferencing' as a[0]=5, a[1]=2,... .
==> But i get segfault when i am trying to allocate -ve bytes of memory.

Second one:
int *a= new int[0];
==> the same effect with 0 size memory allocation and runtime error when trying to allocate (-ve)size of memory.

Third one:
This one, i strongly beleive that it sould raise runtime error, as it is mentioned in C++ standards.
int* a=new int[10];
......
delete a; //Here it should be delete[] a;
==> When an array of objects are created with new operator, while deleting all objects, we should use delete[], instead of delete; since delete will only delete that object.

Fourth one:
Do you think that on freeing or deleting the dynamic memory, the contents/memory locations will be deleted permanantly? No, it shouldn't be. The compiler will just cut of those associated links and the memory locations still with the content that we have assigned. If u want to try, assign the locations to other pointer before freeing/deleting.
My experience is:
int *a=malloc(sizeof(int)*4);
a[0]=1;a[1]=2;a[2]=3;a[3]=4;
int *t;
t=a;
free(a);
printf("%d , %d , %d , %d ",t[0],t[1],t[2],t[3]);
//Answer is "0 , 2 , 3 , 4"

int *a=new int[4];
a[0]=1;a[1]=2;a[2]=3;a[3]=4;
int *t;
t=a;
delete(a);
printf("%d , %d , %d , %d ",t[0],t[1],t[2],t[3]);
//Answer is "0 , 2 , 3 , 4"

==> I am not able to figure out the logic behind making the value of base address to 0 upon deleting. If it is to make value of deleted location as '0', then it should be with all the locations that are dynamically created. But it isn't. And also one more thing is 'write' operation is more costly than delinking.

Your comments are appreciated, if you have proper reasons.

BhimaShankar - One of the 12 Jyotirlingas

Last Saturday i went to BhimaShankar, which is located in the Western Ghats mountain range near to Pune. The distance is 110 km from Pune, and we (me, my friend Sridhar and two of his roommates) went by a cab. The journey is thrilling and the place is located in the far end of the Sahyadri Mountain range. Our trip is just a Half Day only, as we just want to dharshan the Swayambhu Linga. Bhimashankar is also the origin of Bhima River which merges up with Krishna river at Raichur.

This jyothirlinga is one of the famous and ancient ones, which was associated with lord 'Shiva', and has formed upon destroying the demon 'Tripurasara'. If you want to know more about the story and, its formation, refer to this page.

It is believed that the ancient shrine was erected over a Swayambhu Linga or a Self Emanated Shiva Linga. Thus the Linga is exactly in the centre of the floor of the Garbagriha or the Sanctum.

This place gives a wonderful view of Mumbai (ofcourse, which we hav been able to view due to fog), and the hill stations around. Its not more than a pilgrim’s paradise, also a trekker’s delight and traveller’s sojourn. But the ghat road is not so good, and if you opted to go by bus, you will definitely face inconvenience.

This place is good for trekkers as one of the hill is almost 90-deg slope, in the Mumbai side, and i came to know that many trekkers love to climb it. And it is also an extremely dangerous place, if slipped, 100% chances of no survival.

In the near bottom the main hill, there is one point which is said that as origin of the Bhima River. But the disappointing thing is that the Linga was covered up by a silver coating. We came to know that the cover will be released daily twice, once in the early morning 4.30 , and midday 12.00-12.30 pm. The darshan time starts early from 5.30AM and Maha Puja went at 12.00-12.30pm.

Some of the pics that we have taken in the journey.

I am delighted (and a bit busy..)

ఈ రోజు నాకు చాల సంతోషంగా ఉంది. కావలసినంత తెలుగును చదివాను. కొన్ని రోజుల నుంచి నేను అనుకుంటున్నా నాకేమీ పని లేదు, లైఫ్ బోర్ కొడుతుందని. కాని నిన్నటి నుంచి నేను చాల బిజి. కారణం ఏంటో తెలుసా? చాల మంది తెలుగు బ్లగర్స్ వున్నారని తెలుసుకుని, వాళ్ళ బ్లాగులు చదవటం మొదలుపెట్టా. ఇంకా చదువుతూనే వున్నా.

అసలు నాకు తెలుగు ఎందుకు చదవాలని అనిపించింది అంటే, చాలా రోజుల తర్వాత నేను తెలుగులో ఉత్తరం వ్రాయల్సి వచ్చింది, మా మామయ్యకు. ఉత్తరమే ఎందుకు, ఫోన్ చెయ్యోచ్చుగా అనుకుంటున్నరా? ఒక చెక్కు పంపాల్సివచ్చింది. ఉత్త చెక్కును కవర్ లొ పెట్టి పంపలేముగా, దాంతో ఏవో కొన్ని మాటలు రాద్దామని పేపర్ తీసుకున్నా. అంతే! నాకు తెలుగు రాయటం రావట్లేదు. ఎంత ట్రై చేసినా ఇంగ్లీషులోనే పదాలు వస్తున్నాయి. చివరికి నాలుగు ముక్కలు రాసి పోస్ట్ చేసా. ఇంక అప్పుడు నిర్ణయింఛుకున్నా నేను నా తెలుగు ప్రతిభను తిరిగి తెచ్చుకోవాలని. (నా తెలుగు రైటింగ్ చాలా బాగుండేది, కాని ఈ ఇంజనీరింగ్ చదువులు చదివి అంతా మర్చిపోయా.)

వర్తమానంలోకి వస్తే, ఇప్పటి వరకు నేను కొన్ని తెలుగు బ్లాగులు మాత్రమే చదివాను. వాటిలో శోధన, చదువరి, గడ్డిపూలు, స్వాతి కుమారి, క్రిష్ణదేవరాయలు, స్నేహమా, మరి ముఖ్యంగా వీవెన్. ఇంకా నేను చదవ వలసిన బ్లాగులు చాలా వున్నై. వాటిని రేపటికి వాయిదా వేస్తూ....

**Casino Royale** - A Prequel , Reboot and Retcon

"Casino Royale" the name reflects the gambling game where gamblers earn more money fooling the players. Casino Royale is the latest Bond movie to be released on 17'Nov. Its being directed by Martin Campbell, who had directed the movies like "Golden Eye", "Vertical Limit", and "Mask of Zorro". Being a big fan of James Bond i am awaiting for this adventurous venture's release. This new venture is coming with lots of changes from the previous bond movies, and first of all new bond is introducing, Daniel Criag'. Looking at the posters im not able to digest Daniel Criag as James Bond. I still prefer to watch Peirce Brosnon as Bond even he is older.

My curiosity towards Bond movies thrown me to search for new information regarding the Casino Royale. I came to know many interesting points about this venture and may be it is the reason that Brosnon asked for more remuneration. The Casino Royale is the First ever novel of James Bond series written by Ian Flemming. Its going to show James bond differently from the previous sequel. Its a bit serious and non-comedic adaptation of Ian Flemings Story.

Title of this post reflects that its a prequel, reboot, and retcon of the Bond movies. Why it is a prequel is that the story will tell us the necissity of born of James Bond which was narrated by Ian Flemming. Its a Retcon (Retroactive Continuity), coz its going to show something different in JamesBond from the older sequel. And its a Reboot, since Pierce Brosnon was retired from Bond Character and New Bond, Daniel Criag, was adopted.

This movie is against terrorism and Criag is about to stop winning a bank in the Casino Royale game which supports the terrorist groups. Lets wait till Nov'17th to watch the new Bond and his (new)Bond girls.

Note: Eon Productions decided to take another Jame Bond venture with Daniel Criag. Could it be expected that Craig fits well into Bond character?

State of Mind, an experience!

After a long gap of more than two months, i am back to blogging. This post is abt my experience of Soft skills session in our training schedule. I enjoyed this session more and particularly the games which we played individually and as a team learnt us many things which we were not aware of. This is what is terms in behavioural science 'hiding due to blindedness'. Many of us feel that a typical puzzle or game can not be solved by myself, without any others help. But we did came to experience physically as its only our perception of being tough. We played games like 'BrainLock', 'Gammat-Jammat', 'Ring Toss', etc.. But all these games are not only involving analytical thinking, but also requires technical fundas which we might have learnt in school days. Particularly when it comes to the BrainLock game, its too difficult to crack it, without the technical clue, the centrifugal force.

While playing these games, my state of mind is sometimes puzzy and sometimes i forcedly kept it to peaceful to solve the puzzle. But its founded that to solve any kind of problem, our state of mind must be peaceful, for getting the better and productive results.

I want to dwell more into this behavioral science to deal with large number of people. Shd anyone help me out there any kind of books or practices u came across?
