Micromanagement and Macromanagement



Micromanagers

In business management, micromanagement is a management style where a manager closely observes or controls the work of their employees, generally used as a pejorative term. In contrast to giving general instructions on smaller tasks while supervising larger concerns, the micromanager monitors and assesses every step.

Micromanagement may arise from internal sources, such as concern for details, increased performance pressure, or insecurity. It can also be seen as a tactic used by managers to eliminate unwanted employees, either by creating standards employees cannot meet leading to termination, or by creating a stressful workplace causing the employee to leave.

Regardless of the motivation the effect can de-motivate employees, create resentment, and damage trust. Micromanagement can also be distinguished from management by worker to boss ratio. When a boss can do a worker's job with more efficiency than giving the order to do the same job, this is micromanagement.

Micromanagers are managers that oversee their workers too closely. They are constantly looking over your shoulder, commenting positively or negatively. They tend to look at the details of an employees job many times during the work day, usually making unwarranted remarks.
The worker who is micromanaged will reason, "Why can't my boss just let me do my job and leave me alone? What mistakes are they looking for now?"

Micromanages will do compulsive overseeing with both good employees as well as those who are not performing well.

They engage the lowest frequency emotion, FEAR, in the workplace. Fear ----> frustration -----> Depression ---->Sabotage ----> Accidents ----->or Lack of Productivity. Too much micromanagement can cost a company its best and brightest.
This often taps into childhood issues for workers who had dictatorial parents and are now reliving that pain.

Remember that adulthood is often about moving past childhood traumas created in the first 20 years of one's life. In the 21st century we recognize issues, and hopefully deal with them, or else dwell in dysfunctional behavioral patterns, using them as a crutch to not function.
Micromanaging is a compulsive, behavioral disorder similar to other addictive patterns. People who micromanage generally do so because they feel unsure and self-doubting. Sometimes they are pressured by a supervisor above them.

Employees may see them as controlling, dictatorial, judgmental, critical, bureaucratic, snooping, and more.

Do you micromanage? If the answer is Yes and you wonder why no one has brought this to your attention, the obvious answer is that they are afraid of repercussions. Micromanager do not see the 'big picture' because they are too busy dictating font size and controlling everyone else's moves that it totally escapes you and your workers. They are probably not getting your job completed because they are doing everyone else's. They lose the respect of co-workers and fellow employees.

Micromanagers should seek out professional help, perhaps offered by their company. Seek out other fellow managers and discuss how they operate. Have group discussions with your employees to resolve issues.

Macromanagers

On the flip side, we have the Macromanagers.

For the most part they leave their employees with a lack of decision making, especially when the details of the job change and they need immediate assistance.

Employees need guidelines and someone to talk to if they have a problem. Macromanagers leave their employees too much on their own. As a result the lack of direction and input is so lacking that an employee wonders if they are doing the job correctly.

Macromanaging can lead to inefficiency on the part of employees in regards to time spend on the job, work completed, and who they seek out for answers.

A boss who takes on too many projects, moving from one to another, and is therefore not easy to reach for guidance by anyone as he have overextended his time, will never get any of the jobs done properly, will always consider his employees incompetent, and will have to waste company time and money correcting mistakes.

For the best efficiency, there must exist an ongoing communication between employer and employee, that is not dictatorial, but gets the job done in the most efficient way.

There are souls who are very efficient, who do not micromanage, but cannot tolerate the inefficiency of those they work with. Yet they often have to work with people who are not equipped to get the job done, or they just goof off all day playing on the computer, coming in late, leaving early, talking on the phone, gossiping in the office, flirting or having sex with co-workers, etc. Often the efficient employees has to complete or correct the work of the other person. That must be very frustrating.

This takes us to another archived article about firing employees who do not do their job efficiently.
Behavioral scientists propose the presence of three psychological states that could result in a highly motivated and productive worker. The worker must experience:

1. Meaningfulness or significance of their job
2. Responsibility for outcomes
3. Feedback on the work performed

Wise management never underestimates people's pride and dignity for work. Recognition goes a long way. When the environment is happy, work translates to play. Money matters but that's not all there is.

At the end of the day we have to wonder whose fault is it if things go wrong, an inefficient employer who micromanages or macromanages, or an efficient employee who is wrong for the job?

This is almost like balancing a marriage or friendship!

What is HTTP




- HTTP stands for HyperText Transfer Protocol. It is the system for transmitting and receiving information across server and the client. The Server is the machine where your website code is placed and client is nothing but your browser. HTTP manages the mutual understanding between server and the client to exchange information or data successfully. The first HTTP had only one method called as GET, which would request a page from server and the response was a HTML page. The latest version of HTTP defines nine request methods.

- If you visit any website you may see the address gets prefixed with HTTP:// this means your browser is now connected to the server using HTTP. Now the HTTP isn’t the safest way to establish a connection, the problem with http though is that it is vulnerable to people who might want to eavesdrop or see what your activity is all about.


- HTTPS or Secure HTTP some may call it is a combination of Hypertext Transfer Protocol (HTTP) with SSL/TLS protocol. Now everything you communicate over HTTPS will be sent and received in encrypted form, which adds the element of safety.

- As when a client makes a request to the server, the server responds by offering a list of encryption methods. When the client connects to a website via HTTPS, the website encrypts the session with a digital certificate. Secure Sockets Layer or SSL uses a cryptographic system that encrypts data with two keys that is browser and server send each other unique codes which are used for encryption for rest of the talk.

- Https is used in many situations, such as log-in pages for banking, forms, corporate logins, and other applications in which data needs to be secured. It is always advised to never enter credit card details on websites that run on HTTP.


**The Differences between HTTP & HTTPS**

1) In case of HTTP URL begins with “HTTP://” and for HTTPS connection it is “HTTPS://”

2) HTTP is unsecured on other hand HTTPS is secured.

3) HTTP uses port 80 for communication unlike HTTPS which uses port 443

4) No certificates required for validation in case of HTTP. HTTPS requires SSL Digital Certificate

5) No encryption in HTTP; Data encrypted before sending and receiving in HTTPS.

What is SQL Injection?


Is a technique in which an attacker inserts malicious code into strings that are later passed to a database for execution.

It exploits applications that formulate SQL statements from user input. Why would someone attempt SQL Injection?

-Obtain and Delete/Change information you have in your database.

-Cause denial of service (DoS) by injecting SQL that takes a long time to run and perhaps lock rows in your database.

Defending Against SQL Injection Attacks:
-Comprehensive data sanitization. 

Web sites must filter all user input.
Example: e-mail addresses should be filtered to allow only the characters allowed in an e-mail address and so on.

-Use a web application firewall. Example ModSecurity that provides a
filter to potentially dangerous web requests. Its SQL injection defenses
can catch most attempts to sneak SQL through web channels.

-Limit database privileges by context. Example, the code behind a login
page should query the database using an account limited only.

-Avoid Disclosing Error Information. Use structured exception handling to catch errors and prevent them from propagating back to the client. Log detailed error information locally, & return limited error to client.

Any one of these defenses significantly reduces the chances of a successful SQL injection attack. Although there is no such thing as a 100% guarantee in network security, formidable obstacles can be placed in the path of SQL injection attempts.

Windows vs. Mac vs. Linux

Let's start with the most popular: Windows
With almost 90% of the operating system market share, you can't miss Windows. It's in commercial buildings, industrial facilities, as well as home computers. 
Windows, having been introduced in 1985, is a very mature and complete piece of software. Yet, it has it's flaws... 

Pros: 
Compatibility: Almost every application, driver or game will work on Windows.

Cons:
Viruses: You may need to buy an antivirus program, although free ones exist.
Slow: Windows, especially Vista and 7, requires a lot of computer resources (memory, processor, disk space), and thus, runs slower.


Another big player: Macintosh
Apple's Macintosh OS is even older than Windows. It is the first ever successful graphical-based operating system, being released one year before it's Microsoft counterpart. 

Pros:
Viruses: Apple Macs get almost no viruses. This is mostly due to Window's superior market share.
Reliability: Macs only run on Apple computers, and are thus less prone to hardware and software crashing.


Cons: 
Expensive: Mac costs even more than Windows.
Only available on Apple computers: If you already have a computer, you cannot install MAC on it unless it's an Apple. Otherwise, you must buy a new computer.
Compatibility: Only a few programs will run on Mac, and almost no games.


Smaller but growing: Linux
Linux is GNU's answer to Mac and Windows. Yes, this means that Linux is FREE! By free, you can download, modify and redistribute it without spending a dime! . Linux is a younger player in the OS world, having been written in 1991, and is optimized for modern use (well, more than Windows and Mac). Unfortunately, it has some disadvantages also...

Pros:
Price: Linux is F-R-E-E. You can download it, install it, use it, modify it... All for a whooping 0$.
Variety: Linux is not a full operating system. It is just a kernel. To use the kernel, additional software needs to be bundled with Linux. Several hundreds of these bundles (called "distributions" or simply "distros") exist. The most popular ones include Ubuntu, Mint and Fedora. The good thing is, with so many different flavours of Linux, there is always one to suit your needs!

Cons:
Complicated: Although some distros are quite easy to use, most of them will required a good deal of computer knowledge in order to get them to work. 
Compatibility: Like Mac, representing only a few percents of the market share, Linux does not have as many programs and games as Windows.

Bottom line
In conclusion, no operating system is really better, the choice is up to you. If you're a gamer, then you have no choice, go for Windows. Programmers might prefer Linux and video/graphics producers will probably tend towards Mac. The best thing to do is probably to try each OS and see which is best for you!
