Pray for me brother Album by A.R,Rehman

Lyrics:

Pray for me brother
Pray for me brother
Pray for me sister
Are you searchin’….
Pray for me brother

Lookin’ for the answers To all the questions In my life

Will I be alone Will you be there By my side
Is it something he said Is it something he did
I wonder why He is searchin’ For the answers
To stay alive

Could you ever listen Could you ever care

To speak your mind
Only for a minute For only one moment
In time

The joy is around us But show me the love

That we must find
Are you searchin’ For a reason to be kind, to be kind…
He said… Pray for me brother

Pray for me brother Pray for me sister

Pray for me brother Say
what you wanna say now
But keep your hearts open
Be what you wanna be now
Let’s heal the confusion
Pray for me brother

Don’t let me take When you don’t wanna give

Don’t be afraid Just let me live
Don’t let me take When you don’t wanna give
Don’t be afraid Say what you wanna say now
But keep your hearts open

Be what you wanna be now Let’s heal the confusion

Pray for me brother Pray for me brother
I’m ashamed ah, brother be dying of poverty
when he down on his knees its only then he prays
And it’s a shame ah, brother be dying of ignorance
cos the world is a trip and everybody’s a hypocrite
Need to stop ah , taking a look at the other
I’m not ashamed of poverty
need to be making his life better
So think about it, think about it once more
cos life is a blessing and it’s not justa show, ah
Round and round the world is spinning around

We need to be singing a prayer, we need to be singing it now

Round and round the world is turning around
We need to be singing a prayer, we need to be singing it now
Need to be feeling the power, need to be feeling the faith
We need to coming together just to win this race

Need to be feeling the power, need to be feeling the faith

We need to coming together just to win this race (twice)
Are you searching for a reason to be kind ?

Flexible Single Master Operation Roles (FSMO)

Active Directory has five special roles which are vital for the smooth running of AD as a multimaster system. Some functions of AD require there is an authoritative master to which all Domain Controllers can refer to. These roles are installed automatically and there is normally very little reason to move them, however if you de-commission a DC and DCPROMO fails to run correctly or have a catastrophic failure of a DC you will need to know about these roles to recover or transfer them to another DC.

The forest wide roles must appear once per forest, the domain wide roles must appear once per domain.

The Roles

There are five FSMO roles, two per forest, three in every Domain. A brief summary of the role is below.

Forest Wide Roles:

  • Schema Master

The schema is shared between every Tree and Domain in a forest and must be consistent between all objects. The schema master controls all updates and modifications to the schema.
  • Domain Naming

When a new Domain is added to a forest the name must be unique within the forest. The Domain naming master must be available when adding or removing a Domain in a forest.

Domain Wide Roles:

  • Relative ID (RID) Master

Allocates RIDs to DCs within a Domain. When an object such as a user, group or computer is created in AD it is given a SID. The SID consists of a Domain SID (which is the same for all SIDs created in the domain) and a RID which is unique to the Domain.
When moving objects between domains you must start the move on the DC which is the RID master of the domain that currently holds the object.
  • PDC Emulator

The PDC emulator acts as a Windows NT PDC for backwards compatibility, it can process updates to a BDC.
It is also responsible for time synchronising within a domain.
It is also the password master (for want of a better term) for a domain. Any password change is replicated to the PDC emulator as soon as is practical. If a logon request fails due to a bad password the logon request is passed to the PDC emulator to check the password before rejecting the login request.
  • Infrastructure Master

The infrastructure master is responsible for updating references from objects in its domain to objects in other domains. The global catalogue is used to compare data as it receives regular updates for all objects in all domains.
Any change to user-group references are updated by the infrastructure master. For example if you rename or move a group member and the member is in a different domain from the group the group will temporarily appear not to contain that member.

Important Note :

Unless there is only one DC in a domain the Infrastructure role should not be on the DC that is hosting the global catalogue. If they are on the same server the infrastructure master will not function, it will never find data that is out of date and so will never replicate changes to other DCs in a domain.
If all DCs in a domain also host a global catalogue then it does not matter which DC has the infrastructure master role as all DCs will be up to date due to the global catalogue.

Viewing and Transferring Roles

The roles can be viewed and transferred in the GUI or from the command line.

Gui View

Schema Master

To view the schema you must first register the schema master dll with Windows. To do this enter the following in the RUN dialog of the start menu.
regsvr32 schmmgmt.dll
Once you have done this the schema master mmc snap-in will be available.

Active Directory Domains and Trusts

The Domain naming master can be viewed and transferred from here.

Active Directory User and Computers

The RID, PDC emulator and Infrastructure master roles can be viewed and transferred from here.

NTDSUTIL

NTDSUTIL provides FSMO maintenance and the option to seize a role (covered in the FSMO Role Failure section below).
To transfer a role using ntdsutil use the example below as a template for all the roles.
  • Open a command prompt
  • Enter in ntdsutil
  • At the ntdsutil command prompt enter in roles
  • At the fsmo maintenance prompt enter in connection
  • At the server connections prompt enter in connect to domancontrollername
  • At the server connections prompt enter in quit
  • At the fsmo maintenance prompt enter in transfer schema master
  • Quit from the console

FSMO Role Failure

Some of the operations master roles are essential for AD functionality, others can be unavailable for a while before their absence will be noticed. Normally it is not the failure of the role, but rather the failure of the DC on which the role is running.
If a DC fails which is a role holder you can seize the role on another DC, but you should always try and transfer the role first.
Before seizing a role you need to asses the duration of the outage of the DC which is holding the role. If it is likely to be a short outage due to a temporary power or network issue then you would probably want to wait rather than seize the role.

Schema Master Failure

In most cases the loss of the schema master will not affect network users and only affect Admins if modifications to the schema are required. You should however only seize this role when the failure of the existing holder is considered permanent.
Note: A DC whose schema master role has been seized should never be brought back online

Domain Naming Master Failure

Temporary loss of this role holder will not be noticeable to network users. Domain Admins will only notice the loss if they try and add or remove a domain in the forest. You should however only seize this role when the failure of the existing holder is considered permanent.
Note: A DC whose schema master role has been seized should never be brought back online

RID Master Failure

Temporary loss of this role holder will not be noticeable to network users. Domain Admins will only notice the loss if a domain they are creating objects in runs out of relative IDS (RIDs). You should however only seize this role when the failure of the existing holder is considered permanent.
Note: A DC whose schema master role has been seized should never be brought back online

PDC Emulator Master Failure

Network users will notice the loss of the PDC emulator. If the DC with this role fails you may need to immediately seize this role. Only pre Windows 2000 clients and NT4 BDCs will be affected.
If you seize the role and return the original DC to the network you can transfer the role back.

Infrastructure Master Failure

Temporary loss of this role holder will not be noticeable to network users. Administrators will not notice the role loss unless they are or have recently moved or renamed large numbers of accounts.
If you are required to seize the role do not seize it to a DC which is a global catalogue server unless all DCs are global catalogue servers.
If you seize the role and return the original DC to the network you can transfer the role back.

Difference between Cache and Buffer

Key difference: A cache transparently stores data so that future requests for that data can be served faster. A buffer, on the other hand, temporarily stores data while the data is the process of moving from one place to another.

Both cache and buffer are types of temporary storage that are utilized in computer science. However, they differ in the methods and the capabilities in which they are used. A cache transparently stores data so that future requests for that data can be served faster. A buffer, on the other hand, temporarily stores data while the data is the process of moving from one place to another, i.e. the input device to the output device.

There are two main types of caches, memory caching and disk caching. Memory caching is when the cache is part of the main memory, whereas disk caching is when the cache is part of some other separate storage area, such as a hard disk. Caching is the process of storing data in a cache so that the data can be accessed faster in the future. The data that is stored within a cache might be values that have been computed earlier or duplicates of original values that are stored elsewhere. When some data is requested, the cache is first checked to see whether it contains that data. The data can be retrieved more quickly from the cache than from its source origin.

An easy example to understand caching is to look at web caching. A web cache is a mechanism for the temporary storage (caching) of web documents, such as HTML pages and images. This is mainly done to reduce bandwidth usage, server load, and perceived lag. When a web page is loaded, the data on the pages is cached; hence the next time the page is loaded it is quicker, as data is already present, and only the changes made to the page need to be loaded, which are in turn cached for next time. Google's cache link in its search results provides a way of retrieving information from websites that have recently gone down and a way of retrieving data more quickly than by clicking the direct link.

The buffer, on the other hand, is found mainly in the RAM and acts as an area where the CPU can store data temporarily. This area is used mainly when the computer and the other devices have different processing speeds. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a mouse) or just before it is sent to an output device (such as speakers). However, the buffer may also be used when moving data between processes within a computer.

So, the computer writes the data up into a buffer, from where the device can access the data, as its own speed. This allows the computer to be able to focus on other matters after it writes up the data in the buffer; as oppose to constantly focus on the data, until the device is done.

Buffers can be implemented in a fixed memory location in hardware or by using a virtual data buffer in software, which points to a data buffer are stored on a physical storage medium. Majority of the buffers are utilized in the software. These buffers typically use the faster RAM to store temporary data, as RAM has a much faster access time than hard disk drives. A buffer often adjusts timing by implementing a queue or FIFO algorithm in memory. Hence, it is often writing data into the queue at one rate and reading it at another rate.

A common example of this is streaming videos online, such as YouTube. While, watching a video on YouTube, one may notice that a gray bar tends to load before the red bar of the video stream can play. The gray bar is the buffer. It downloads the data of the video and saves it so that the video may play at an uninterrupted rate. As you might have noticed that when the red bar catches up to the gray bar, the video stops, in order to load the rest of the video.

Buffers are also often used with I/O to hardware, such as disk drives, sending or receiving data to or from a network, or playing sound on a speaker. Buffers are used for many purposes, such as interconnecting two digital circuits operating at different rates, holding data for use at a later time, allowing timing corrections to be made on a data stream, collecting binary data bits into groups that can then be operated on as a unit, and delaying the transit time of a signal in order to allow other operations to occur.

However, a buffer cannot be used to instantaneously move your location in the data stream, unless the new part has already been moved to the buffer. Similar to the YouTube video, which cannot be forwarded to a part that is not covered by the gray bar.  If you do, the buffer will relocate and restart from the new location.

Still, the functions of a cache and buffer are not mutually exclusive and are often combined for an ideal performance.

This registry trick works good in windows XP for not checking the low disk space.

Interview & Workplace Tips

You can never be sure exactly what will happen at an interview, but you can be prepared for common interview questions. Take time to think about your answers now. You might even write them down to clarify your thinking. The key to all interview questions is to be honest, and to be positive. Focus your answers on skills and abilities that apply to the job you are seeking. Practice answering the following questions with a friend.

"Tell me about yourself."
Sounds simple, doesn't it? On the other hand, where do you start? The interviewer is looking for a quick overview of your career and your academics. What the interviewer doesn't want to hear is about your family, pets, hobbies, boyfriend/girlfriend, or the funny thing that happened to you yesterday. What they're really asking is, "Tell me about your professional self." The best way to answer this is to give a brief summary of your career so far, focusing on specific accomplishments. Try something like this: "My first job was as a receptionist at XYZ Corporation, but I was promoted after just three months. I worked my way up to sales manager for the Northeast. I doubled sales in the Northeast, and brought in ten new clients in my first quarter."
Finally, explain why you're looking for a job. But don't bad-mouth your current job or your boss; it will reflect poorly on you. Say something like: "Now I'm looking for a new challenge." This is also a good time to throw in some of the information you've learned in your research about the company: "I'm looking for a company with a dedication to preserving the environment and I believe your company offers that."

"Why do you want to work at this company?"
This is where you get to show that you have researched the company and you are more than just an average applicant. Relate something you learned about the company and explain why this attracted you to them. If the company has a commitment to the community, you might say you appreciate their commitment and that is what draws you to them. Or you understand that they are in a competitive battle with another major company and you relish the challenge of helping them carve out a bigger market share. If you heard about the job from a friend of family member, you could mention that person. But don't forget to include something that shows that they should want to hire you. "My friend has worked here for years and says it's a great company to work for with great people to work with. I think I could really contribute to your team."

"What did you like/dislike about your last job?"
This is a tricky one, because you don't want to come off as overly critical, petty, or a problem employee. If you say you hated dealing with the general public, you can be assured you won't be hired in retail sales or customer service. If you say you hated your boss, the interviewer will worry about you hating them someday. Keep your answer positive. If you mention something you disliked about the company, pair it with something you liked. Let's say that you worked as a receptionist, and your boss was condescending to you and never gave you anything interesting to do. You could say, "I enjoyed greeting the public, and I liked knowing that I could make a difference by giving people a great first impression of the company, but I felt that there wasn't room for me to contribute my organizational and teamwork skills. I'm ready for a position that offers more responsibility and more challenge."

"What is your biggest accomplishment?"
Be specific. Tell about one thing that you did really well. Preferably, talk about something that was recognized and rewarded by your boss. You could say something like, "I created a system to organize my boss's projects and deadlines, which often overlapped. He was so impressed, he told other managers in the group, and I ended up training the other secretaries to create similar systems for their bosses." If you are applying for a position that involves being part of a team, recount something you did as a member of a team, and talk about the teamwork and cooperation that was required.

"What is your greatest strength?"
Even if your greatest strength isn't business-related, find a way to relate it to work. Your greatest strength may be your ability to memorize lyrics to pop songs, but if you're applying for a job as a sales trainee, they won't really care. They will care that you have a great memory and are good at keeping information organized. If you're a great basketball player, talk about how well you deal with pressure and work as part of a team.

"What is your greatest weakness?"
The interviewer who asks this question is looking to see how honest you are with yourself, and how well you deal with your own shortcomings. Don't pretend you don't have weaknesses, and don't avoid answering the question. This is your chance to show that you are honest and take responsibility for your actions. A good way to answer this question is to mention your weakness, then tell what you have done to overcome that weakness. If you have been disorganized in the past, you could say, "I used to be very disorganized, always forgetting assignments and birthdays. But I managed to work out a computerized system of to-do lists and reminders that keeps me on top of everything."

"Do you prefer to work with others or on your own?"
This is a question you should have asked yourself before you applied for the job. The interviewer wants to make sure that you are appropriate for the job for which you are applying. If you're going to be part of a team, you should enjoy working with others. On the other hand, if you're going to be doing data entry, it might be a good idea if you enjoy working on your own. Remember, however, that companies don't want to hire workers who need constant hand holding. A good answer might be, "I enjoy being part of a team and cooperating with others, but I also enjoy working on my own. At my last job, our team would meet to discuss our goals, then each work on our part of the project individually. There was a lot of communication and cooperation among the group, but I was responsible for completing part of the project on my own."

"What are your career goals?" or "Where do you see yourself in five years?"

The interviewer is wondering how dedicated you will be to the job and the company. If they are going to train you, they want to know that you aren't going to take the next job that comes along. On the other hand, most companies don't want to hire people who have no ambition at all. Even if you have no idea where you want to be in five years, don't say, "I don't know." Be positive. Say something like, "I hope to be in a position that continues to challenge me, and that allows me to use my skills and abilities to help the company reach its goals." Ideally, the job you're applying for is a step on your career ladder, so you can talk about the career ladder you've envisioned for yourself. Employers like to hear that you are interested in staying and growing with their company.


"Tell me about a time that you had a lot of work to do in a short time. How did you manage the situation?"
Here, the interviewer is looking for specific strategies that you use to manage pressure situations. Talk about prioritizing your work, cooperating with others, making to-do lists, breaking large projects into small batches, and taking care of your health so you could maintain your concentration.

"Have you ever had to work closely with a person you didn't get along with? How did you handle the situation?"
The interviewer wants to hear that you were able to put aside your differences and get the work done. They also want to hear that you are flexible, and can be sensitive to the needs and feelings of others. If you don't have a work-related example, talk about a school project, or about being part of a club and learning to get along with the various people in the club.
