Benefits of migrating Workgroup to Active Directory domain

During making decisions about company's infrastructure decision-makers face the problem of managing users and equipment located in various locations. Users possess different knowledge about IT things, mainly adapted to their workplace environment. Software, hardware, operating systems, sometimes means nothing for them. Employees are part of departments that can work together or on the contrary - they should not be part of the team. To prevail on this diversity and to ensure an adequate level of security, Microsoft introduced Active Directory, which catalogs users data, computers, peripherals and allows for easier and automated management.
There are many companies which started their work on one or few computers, grew slowly and suddenly bloomed to be businesses with hundreds of users. On the other hand the IT environment was not changed accordingly to company needs. Computers was still the part of working group, being really just a collection of independent units. This made it difficult to manage them as a resources. In this article, I will present the differences between the working group and the Active Directory domain and the advantages of the latter solution.

What the Workgroup is?

This is a group of computers, which are working independently in the company, but can share some elements, like documents. They could work in the same physical network or in the other company's location. They are not managed centrally.

Active Directory Certificate Services Overview

Applies To: Windows Server 2008, Windows Server 2008 R2
Active Directory Certificate Services (AD CS) provides customizable services for issuing and managing public key certificates used in software security systems that employ public key technologies.
In the following sections, learn more about AD CS, the required and optional features, and hardware and software used for running AD CS. At the end of this topic, learn how to open the management interface for AD CS and how to find more information.

Features in AD CS

By using Server Manager, you can install the following components of AD CS:
  • Certification authorities (CAs). Root and subordinate CAs are used to issue certificates to users, computers, and services, and to manage certificate validity.
  • CA Web enrollment. Web enrollment allows users to connect to a CA by means of a Web browser in order to request certificates and retrieve certificate revocation lists (CRLs).

7 exciting facts about boredom

If there are three words that can make reasonable adults bristle, balk or erupt, three words that most children and teenagers utter with frequency, three words that annoy and worry us and which immediately precede many conflicts, impulsive decisions and activities of distraction, it’s these: I am bored.
Why do we feel so irritated by the utterance of this phrase?
What is it about the thought of our children being bored that can prick our hearts, jumble our minds, send us either scrambling for solutions, reeling with rage or shrugging in disbelief and resignation?
Many adults take it personally. Boredom can trigger feelings of frustration in parents if they think their kids have a “million things to do,” as many parents say, and especially if they have invested energy, time and money keeping kids busy.
But, bored is not the opposite of busy. The antidote to boredom is not over-scheduling.
Documentary filmmaker Albert Nerenberg says, “The biggest misconception about boredom is that it is just a sleepy irritant.”
Nerenberg, whose movie “Boredom’’ explores the subject in education and life, is a social researcher and a “laughologist.”
Based in Montreal, Canada, he travels the world interviewing people for his projects, leading “Laughing Championships,” and helping people in crisis through the power of laughter and hypnotherapy.
“I would say the expression ‘boredom’, which was essentially coined by the English in the 19th century, is universal.”
We have vague notions about boredom, what it is, what to do in the face of it both in our children and in ourselves, in the workplace and in the classroom. In our age of high-speed everything, how do we preserve our curiosity, sow seeds of patience, cultivate wonder and hard work?
Sometimes, it’s not what we’re doing but where we are doing things. Context is always key.
“All of us get into habits in certain locations,” says Bernadette Hennessy May, owner of Rhinoceros Toys in Haddonfield. “We get comfortable playing computer or other electronic games at home, but when kids are out of the house, the change in environment creates an atmosphere that offers an opportunity to try something new.”
Something new.

The first known use of the word “computer” was in 1613 in a book called The Yong Mans Gleanings by English writer Richard Braithwaite. In it he said, “I haue read the truest computer of Times, and the best Arithmetician that euer breathed, and he reduceth thy dayes into a short number.” (The spelling mistakes were all deliberate BTW, it was a simpler time back then).
Braithwaite was referring to a person who carried out calculations, or computations. Today, most of that work is handed over to the metal and plastic slabs we have on our desk.
But how did a box of cables and circuits became so dang smart? Here we comb through the annals of history and the lesser known corners of computer programming to find 10 tidbits every computer programmer should know.
