Problems of public toilet in karachi

Note :As the public toilet issue in Karachi is very huge and too difficult to study, it may contain several places like public places, bus stops, van stands, cinema houses, theatre halls, markets, school, colleges, universities, railway stations, airports and so on. But in this report  the Government Hospitals & Bus Stops will be discussed and only few part of public places will be considered. The information in this report will be of 11% from internet & 89% of my own research and meeting with different people who faced this problem...


INTRODUCTION
Public toilets are toilets open to anybody, in public places or in residential areas: typically there will be a charge for each use. Sometimes charging will be monthly: each users pays for a monthly ticket. Mostly users prefer to pay per time use. Users of public toilets will generally feel less ownership other user’s toilets. In
Karachi: 42% of the city’s population is without proper toilet drainage.


NEED FOR AN ACCESSIBILITY OF PUBLIC TOILETS
As Karachi is the highly dense populated city. The city has an estimated population is 13 to 15 million, while the total metropolitan areas has a population over 18 million. Large number of people daily travels through bus from on corner to the other corner of city. In this regard many people travel with staying at different stations or point. So at different stations of bus stops or lateral traveling point of common people which are usually traveled through bus or by walk, sometimes people needs toilet for their ease. In Karachi many bus stops needed toilets or a place where the human consumption rate is rarely high.
In the same manner Government Hospitals also required a lot of care of toilets in their respective departments, in order to facilitate the doctors, patient and the people who care their patients.


Public Places is also another main factor where the need of public toilets is usually high, like amusement parks, gardens, museums, towers, shopping malls, spiritual places etc. The description of the above topics will be given below with several reference context, in which it will be discussed there lack ness in the e city, importance, rehabilitation and suggestions.

IMPORTANCE
People commuting different areas of city & staying at different points, visiting & circulates to their desire places need restrooms. For the sake of people easiness, toilet must be available at different to facilitate the peoples.
The following places needed immediately action from the concerned government departments for having public toilets.
These places will be discussed in this report are as follows:

Gul bahao organization and its Chandni ghar

Gul bahao Organization :
Gul bahao Launched in 1994 .The concept of Gul Bahao stems from two incidents in Ms Nargis Latif’s life. Following the birth of her third child, Nargis suffered immense trauma and illness and she vowed that if God relieved her of her misery, she would take a keener interest in social work. A few years later, when Ms Nargis had fully recovered and resumed normal life, she got into an argument with a garbage cleaner beneath her apartment who insisted on burning trash in a dumpsite outside her flat. Livid at why the trash had to be burned instead of disposed off in a more appropriate manner, Nargis was determined to find alternate solutions for the pestilent problem. Learning that the cost of clearing up a single garbage site was pretty steep (Rs 4,000 back then), the young Nargis took to scouring libraries for better options and eventually came to the realization that facilitating garbage disposal was not just a day’s work; it entailed a lifetime of commitment. According to Ms. Nargis : “ I realised I would have to sacrifice a cosy, comfortable family life for it “

Who is Nargis Latif ?
Born and raised in a lower middle class family, Nargis initially pursued a career in journalism. During ten years of work in that field, however, she became increasingly convinced that waste disposal problems in Karachi were assuming critical proportions and not receiving the attention that they deserved. Accordingly, in spite of resistance from her family, she decided to abandon her journalistic pursuits and devote her full energies to the search for creative and effective ways of addressing waste disposal needs. Now in her mid-forties and married with three children, Nargis has pursued her work in the waste disposal and environmental awareness fields with very limited financial support. Apart from the proceeds of commercial advertising banners in her dry trash stalls, she has developed the ventures described above as a labor of love. She regards herself, in fact, as an independent researcher engaged in a continuing search for new and better ways to convert waste and garbage into useful economic commodities. And Now She is the head of Karachi based NGO Gul Bahao for over a decade now Nargis Latif has developed a campaign to help solve the staggering waste disposal problems of the city of Karachi and to encourage broad adoption of environmentally and socially responsible waste disposal practices. The core of her initiative is an imaginative recycling program that is carefully attuned to the city's economic and social conditions.

Linux basic commands

LINUX BASIC COMMANDS:

Following are some basic commands use in linux system

Terminal:

The terminal is often called the command prompt or the shell. In days gone by, this was the way the user interacted with the computer, however Linux users have found that the use of the shell can be quicker than a graphical method and still holds some merit today.

cd       Change Directory

ls       List information about file(s)

make     Recompile a group of programs

gzip     Compress or decompress named file(s)

install  Copy files and set attributes

kill     Stop a process from running

killall  Kill processes by name

sudo     Execute a command as another user

Wget     Retrieve web pages or files via HTTP, HTTPS or FTP

Apt-get  Search for and install software packages (Debian/Ubuntu):

APT (Advanced Packaging Tool) is a powerful package management
system.APT automatically handles
dependencies and performs other operations on system packages to allow the
installation of the desired package/s.

Some common commands that can be used with APT:

Install packages:

# sudo apt-get install packagename

Remove packages:

# sudo apt-get remove packagename

Retrieve new lists of packages:

# sudo apt-get update

Upgrade system with available updates:

# sudo apt-get upgrade

Directories and file system of linux

Linux and Unix file systems are organised in a hierarchical, tree-like structure. The highest level of the file system is the / or root directory. In the Unix and Linux design philosophy, everything is considered a file - including hard disks, partitions and removable media. This means that all other files and directories (including other disks and partitions) exist under the root directory.

Underneath the root (/) directory, there is a set of important system directories that are common across most Linux distributions that are used.

The following is a listing of common directories that are directly under the root (/) directory

•         /bin - important binary applications
•          /boot - boot configuration files
•          /dev - the device files
•          /etc - configuration files, startup scripts, etc...
•          /home - local users' home directories
•        /lib - system libraries
•         /lost+found - provides a lost+found system for files that exist under the root (/) directory
•          /media - mounted (loaded) removable media such as CDs, digital cameras, etc...
•          /mnt - mounted filesystems
•          /opt - provides a location for optional applications to be installed
•          /proc - special dynamic directory that maintains information about the state of the system, including currently running processes
•          /root - root user home directory, pronounced 'slash-root'
•         /sbin - important system binaries
•         /sys - system files
•          /tmp - temporary files
•          /usr - applications and files that are mostly available for all users to access
•          /var - variable files such as logs and databases

All of the files on a Linux system have permissions that allow or prevent others from viewing, modifying or executing. The super user "root" has the ability to access any file on the system. Each file has access restrictions, user restrictions and have an owner/group association.

/bin:
The first directory we get to is /bin. Its name is derived from the word "binary." Often, the word "binary" is used to refer to executable programs or other files that contains non-readable characters. The /bin directory is where many of the system-related binaries are kept, hence the name. 

Introduction to unix and linux

INTRODUCTION TO UNIX:

UNIX is an operating system which was first developed in the 1960s, and has been under constant development ever since. By operating system, we mean the suite of programs which make the computer work. Knowledge of UNIX is required for operations which aren't covered by a graphical program, or for when there is no windows interface available, for example, in a telnet session. Unix was primarily oriented towards the command line interface, and that legacy is carried on in Linux. Thus, the graphical user interface with its windows, icons and menus are built on top of a basic command line interface. Furthermore, this means that the Linux file system is structured to be easily manageable and accessible from the command line. Many of the design conventions behind Unix also exist in Linux and are central to understanding the basics of the system

The UNIX operating system is made up of three parts:

·         The kernel

·         The shell

·         Programs

Kernel:

The kernel of UNIX is the hub of the operating system: it allocates time and memory to programs and handles the filestore and communications in response to system calls.

Shell:

The shell acts as an interface between the user and the kernel. When a user logs in, the login program checks the username and password, and then starts another program called the shell. The shell is a command line interpreter (CLI). It interprets the commands the user types in and arranges for them to be carried out.

INTRODUCTION TO LINUX:

Linux is a free multitasking, multi-user network operating system that behaves like Unix. That means Linux is not UNIX. It is a UNIX-based operating system. It was designed specifically for the 386(x86 Intel CPU) platform and released under GNU General Public License. Linux is technically only the kernel,

Quakelive vs Counter-strike 1.6

Quakelive and counter strike 1.6 both are the FPS (first person shooter) multiplayer games. Both of them has a very long history. Talking about the Quakelive first, it is one of the game that can be played directly from your browser. When you signup on quakelive, it allow you to play free but if you want to enhance your abilities and skill level you can go for premium and pro level. The premium subscriptions can be purchase for €1.99 per month and pro for €3.99 per month. Quakelive is not a game with real guns like in counter strike it has something futuristic maps and guns like rockets, rails, lightning gus with teleports and jumping pads etc. There are twelve types of guns and around forty plus maps on this game, though not all of these maps are available to normal players you must have to go for premium/pro service for all maps.There are two teams red and blue team and five game modes are available for normal players.

• Duel: for 1o1 match
• Free for all: where all players fight for themselves. In a given time interval one must have to reach to its frag limit for win
• CTF (capture the flag): there are two teams with flags on their bases. in order to win one team must have to bring other team flags to their base.
• TDM (team death match): Same like Free for all, but they are divided into two teams
• Clan area: where two teams fight like as in counter strike
• Freezetag: for premium/pro users only, similar to clan area but instead of frag they become frozen

On the other hand Counter strike is a world's number one tactical first person shooter team based game, in which two teams terrorist and counter-terrorist equipped with different guns and gadgets, like Maverick M4A1 Carbine, Magnum Sniper Rifle (AWP), AK-47, Night-vision, bomb diffuser etc, engaged in a terrorist warfare. Counter-terrorist can win by either defusing the bomb and eliminating all terrorist or killing oor terrorist before they plant the bomb otherwise if bomb blown the terrorist will win the round. On some map there are some hostages or VIPs, by rescuing them the counter-terrorist can win the round.

Problems of U-turns in karachi

INTRODUCTION

What is u-turn and why they are provided?

A U-turn in driving refers to performing a 180 degree rotation to reverse the direction of travel or the turning of a vehicle in a U-shaped course so as to face in the opposite direction. It is called a "U-turn" because the maneuver looks like the letter U.  In some areas, the maneuver is illegal, while in others it is treated as a more ordinary turn, merely extended. In still other areas lanes are occasionally marked "U-Turn only”.

In Karachi u-turns of different designs can be seen mostly on every road. The construction of these u turns on many roads of the city was aimed at providing convenience to motorists and citizens while traveling on long corridor but many people are facing problems due to u-turns. 

Advantages of u-turns:

The purpose of the construction of u-turns was to provide convenience for the drivers and for the smooth flow of traffic so that people reach their destination easily while traveling on signal free corridors. Some of the advantages of modern u-turns (separated lane u-turns) are as below:

·          1.  Easy travelling for the motorists and citizens without any interruption which was present  before the construction of separate lane u-turns.

·           2.  Increases queuing space for left-turning vehicles.

·           3. Save travel time

·          4. Free flow of the traffic (if there is no blockage)

       

        

       PROBLEMS DUE TO U-TURNS

There are many problems we are facing in our daily life during travelling from one place to another due to bad design and unplanned u-turns. For example effect of u-turn on the flow of traffic, traffic congestion and wrong way driving
