ASTERISK DATASHEET

Download Base Files of Asterisk:

http://downloads.digium.com/pub/asterisk/

Required packages

• Minimal install
• kernel-devel / kernel-smp-devel
• bison
• openssl-devel

or mysql support

• mysql
• mysq-server
• mysql-devel

Installation process

Select minimal from the Package Group selector option (on Centos 4.1 this required just disk1 for my hardware - HP DL360 - G4)
When the installation completes, install the YUM GPG Key

• rpm–import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-4

Now simply install the required packages using yum

• yum -y install kernel-devel bison openssl-devel

or to include mysql:

• yum -y install kernel-devel bison openssl-devel mysql mysql-server mysql-devel

If you run an SMP kernel, you need kernel-smp-devel instead of kernel-devel above.

Now go make yourself a cup of tea/coffee as this will take a while, depending on your connection speed (it will download and install all dependencies and packages required)

Then:

• yum -y update

Another cup of coffee, and a reboot to ensure that you compile against the correct kernel.

Once installed, standard asterisk installation procedure applies.

Installing Asterisk on to CentOS 4.x

Quick and Easy Install Guide, continuing from above section.

*** If you are running an SMP kernel, then instead of “kernel-devel” use “kernel-smp-devel”***
*** MySQL is optional, MenuSelect requires ‘ncurses-devel’ if you want to set extra options. ***

Install prereqs:

yum -y update
yum -y install gcc gcc-c++ libtermcap-devel kernel-devel bison openssl-devel mysql mysql-server mysql-devel

Everyone wants programmers to be productive. Managers of programmers want maximum productivity — it gets the work done faster and makes the managers look good. All other things being equal, programmers like being productive. They can get home earlier, reduce stress during the workday, and feel better about their finished products. Unfortunately, the standard definitions of software productivity are incorrect. They miss the essence of software development. What are the usual definitions for programmer productivity? Why are they wrong? Read below.

Usual definitions for programmer productivity

Lines of code per day — This is the classic definition of software productivity for individual programmers. Unfortunately, as other authors have noted as well, the definition makes little sense. Imagine a programmer named Fred Fastfinger who writes 5000 lines of code, on average, each workday. Now assume Fred’s code is of such poor quality that, for each day of work he does, someone else must spend five days debugging the code. Is Fred highly productive? Certainly not. What we want is many lines of good code.

Lines of correct code per day — This definition adjusts for the problem of a programmer producing lousy code. In the above example, using the new definition, Fred’s productivity becomes 833 lines/day (5000 lines, divided by one person-day to write the code plus five person-days to fix it). But even this definition is lacking. Suppose Fred cleans up his act and begins to produce 1000 lines of correct code per day by himself. Imagine his code is completely bug-free, but contains no comments at all. Is Fred productive now? Probably not. The code may be correct based on the current specification, but we know software requirements always change. The next programmer to take over Fred’s code will find it impenetrable, and possibly will be forced to rewrite the code in order to add any new features. (Even Fred will likely find his code opaque in a few months.)

Lines of clean, simple, correct, well-documented code per day — This is a pretty good definition of productivity, and one many experienced, savvy technical managers would accept. There is still something about this definition though that misses what software engineers ultimately are trying to do. Imagine Fred, Danny, and a third programmer, Ingrid Insightful, are given similar assignments. Fred and Danny head right to their desks and begin writing good code. Something about the assignment bothers Ingrid however, so she decides to go outside for a walk. After a lap around the park, she buys a decaf mochaccino, sips a little, and lies down under a tree. Soon she falls asleep. A half-hour later, Ingrid wakes up with a start and realizes what bothers her about the programming assignment: this new feature is suspiciously like an existing feature. She strolls back to her desk, nods to Fred and Danny, and looks over the code base. Sure enough, the new feature she was asked to create is actually a generalization of another special-case feature.

Ingrid opens up the source code for the existing feature and begins deleting large sections of it. Before long, she has generalized the existing feature so it is simpler, more intuitive, and includes the new capabilities she was asked to add. In the process, she has reduced the code base by 2000 lines. Around 3:00, Ingrid says goodbye to Fred and Danny, and heads to her health club to work off the mochaccino.

Who was more productive on this day? Certainly Ingrid. Fred and Danny are not even finished creating their features yet. Ingrid’s feature works completely, she has simplified the entire program, and the user interface is improved by reducing the apparent feature count. But note Ingrid’s productivity included writing negative 2000 lines of code and spending little time in the office. While this example may seem fanciful, it is actually quite realistic. Getting away from a problem sometimes is a good way to solve it. And programmers who understand the big picture make smarter decisions, because they are able to reuse code and combine features effectively.

Ability to solve customer problems quickly — This is the true definition of programmer productivity, and is what Ingrid accomplished in the example. I use the term customer very loosely. The customer may be a group of users in the same organization, a fighter pilot whose aircraft depends on the software, the world at large (for open source programmers), or yourself when writing a software tool. What software engineering really is about is solving problems for the people who will use the software. Any other definition of programmer productivity misses the mark.

This definition raises a difficult question though: If a programmer can be highly productive by writing a negative amount of code, how do we measure productivity for software engineers? There is no easy answer to this question, but the answer surely is not a rigid formula related to lines of code, bug counts, or face time in the office. Each of these measures has some value for some purposes, but managers should not lose site of what software engineers are doing. They are creating machines to solve human problems.

For the small teams; its understandable; you usually don’t have enough resources (human, time, finance) and to cover this; here are few suggestions

Requirement Gathering & Analysis
Create a mailing list or forum for the project and make your team part of it. Discuss your requirement over emails/threads; and assign one person to send a periodic email/post summarizing the discussions. The last such email/post will lead you to requirement specifications.

Project Plan
Ask your team to divide the project into components and give estimated dead line. Do this again on the email list. Once done; write the summary for every commitment; discuss it in a thread. The last such email/post will be your project plan. Rewrite this in a new post/email; and then keep posting the replies to this whenever there is any change in the plan. Each reply should contain up to date commitments.

Design / Implementation
I strongly recommend using WIKI, Sharepoint or other such web enabled collaboration platform. Write your design/implementation documents there. On each deadline/milestone; take a snapshot of current versions of documents/artifacts; mentioned below

Database
Use diagramming support of modern database engines; SQL Server supports this. Your diagram will be up to date always.

Design
Encourage your team to use contract driven development; use interfaces (interface IFunctinoality {}). Your design artifacts can then easily be created using some round-trip modeling tools like Borland’s Together or Rational’s XDE

Implementation
Encourage your team to at least mention WIKI/Sharepoint URLs in the comments. Modern IDEs (like Visual Studio) has built in browser and you can easily correlate code with the documentation.

Data Layer
Use approach of least access; in database access layer; keep separate logins for developer’s access (SQL Server’s Enterprise Manager / Query Analyzer) and your application access. The developer login can have full access to the database but the login being used for the application should have least access. This way seeing which objects the application login has access will leads you to dependency information. It’s also suggested to write auditing code in stored procedures; so that you can pin point “dormant objects” easily.

Middle Layer
Encourage your team to log method names, parameters being passed and backend (sql query or web service name/url) being used in each method. Such log file will lead you to the dependency information. Audit these log files; and to check bottle necks.

User Interface Layer
Use patterns like Model view presentation; the view interfaces will help you to keep things in control and reflect changes across user interface and middle layer easily. Counts of such interfaces will also help you estimate the size of your application.

Etc Etc
Use emails/forums; encourage your team, not to leave the office/workplace unless a status of what has been done and what you will do the next day is informed to the project email list / forum. The team lead should write periodic emails for “To Dos” and “Status” such emails/posts will help you write status summaries for the management.

Also encourage your team to write postmortems on each milestones or on periodic basis. Let them write what they feel and wish. Keep such email/forum threads separate; they will help you to improve your processes for the next project.

Don’t forget to post your comments and suggestions. Cheers

Tethyan Copper of Australia has taken the contract to develop this mine. Barrick Gold Corporation of Canada and Antofagasta of Chile have a joint-ownership of the copper-gold deposit at Reko Diq.
The Reko Diq deposit is being explored by Tethyan Copper Company Pty Ltd (75%) and the (BDA)Balochistan Development Authority (25%). Tethyan Copper Company is held jointly (50:50) by Barrick Gold Corporation and Antofagasta Minerals.

Currently the deposit is at scoping / pre feasibility stage.. It is a world class copper / gold porphyry style deposit, typical of the tethyan belt.

It has been sold to the Zionist controlled regimes by the Pakistani Government under the dictator at a price of $21 billion. Rough estimates suggest that the gold and copper at the surface accounts for $65 billion worth of deposits.
Tell me how many of us know about it …remember the total debt on Pakistani Nation is $38b.

Now the question is why Pakistani media and Govt is silent about it? why it is kept secret from Pakistani Nation?

Then I saw their ad these people was asking to sign something, I just caught their website name. Then I visit their website, and I found their service (social service) great, to bring the real face of Islam to all over the world. Some people spreading terror using the name of Islam but they are not Muslim, they are just shit, they don’t know the name of Islam. Islam word came from “Salam” which mean Peace. And Islam mean Religion of Peace. I proud that I’m Muslim Alhamdullilah.

When asked to explain the price of eggs the store owner says, “The price has
gone up and I have to raise my price accordingly”. This store buys 100 dozen
eggs a day. He checked around for a better price and all the distributors
have raised their prices. The distributors have begun to buy from the huge
egg farms. The small egg farms have been driven out of business. The huge
egg farms sell 100,000 dozen eggs a day to distributors. With no
competition, they can set the price as they see fit. The distributors then
have to raise their prices to t he grocery stores. And on and on and on.

As the man kept buying eggs the price kept going up. He saw the big egg
trucks delivering 100 dozen eggs each day. Nothing changed there. He
checked out the huge egg farms and found they were selling 100,000 dozen
eggs to the distributors daily. Nothing had changed but the price of eggs.

Then week before Thanksgiving the price of eggs shot up to $1.00 a dozen.
Again he asked the grocery owner why and was told, “Cakes and baking for the
holiday”. The huge egg farmers know there will be a lot of baking going on
and more eggs will be used. Hence, the price of eggs goes up. Expect the
same thing at Christmas and other times when family cooking, baking, etc.
happen.

This pattern continues until the price of eggs is 2.00 a dozen. The man
says, “There must be something we can do about the price of eggs”.

He starts talking to all the people in his town and they decide to stop
buying eggs. This didn’t work because everyone needed eggs.

Finally, the man suggested only buying what you need. He ate 2 eggs a day.
On the way home from work he would stop at the grocery and buy two eggs.
Everyone in town Started buying 2 or 3 eggs a day.

The grocery store owner began complaining that he had too many eggs in his
cooler. He told the distributor that he didn’t need any eggs. Maybe
wouldn’t need any all week.

The distributor had eggs filing up at his warehouse. He told the huge egg
farms that he

Didn’t have any room for eggs would not need any for at least two weeks.

At the egg farm, the chickens just kept on laying eggs. To relieve the
pressure, the huge egg farm told the distributor that they could buy the
eggs at a lower price.

The distributor said, “I don’t have the room for the eggs even if they were
free”. The distributor told the grocery store owner that he would lower
the price of the eggs if the store would start buying again. The grocery
store owner said, “I don’t have room for more eggs. The customers are only
buying 2 or 3 eggs at a time. Now if you were to drop the price of eggs
back down to the original price, the customers would start buying by the
dozen again”.

The distributors sent that proposal to the huge egg farmers but the egg
farmers liked the price they were getting for their eggs but, those chickens
just kept on laying. Finally, the egg farmers lowered the price of their
eggs. But only a few cents.

The customers still bought 2 or 3 eggs at a time. They said, “When the price
of eggs gets down to where it was before, we will start buying by the
dozen.”

Slowly the price of eggs started dropping. The distributors had to slash
their prices to make room for the eggs coming from the egg farmers.

The egg farmers cut their prices because the distributors wouldn’t buy at a
higher price than they were selling eggs for. Anyway, they had full
warehouses and wouldn’t need eggs for quite a while.

And those chickens kept on laying.

Eventually, the egg farmers cut their prices because they were throwing away
eggs they couldn’t sell.

The distributors started buying again because the eggs were priced to where
the stores could afford to sell them at the lower price.

And the customers starting buying by the dozen again.

Now, transpose this analogy to the gasoline industry.

What if everyone only bought $10.00 worth of gas each time they pulled to
the pump? The dealer’s tanks would stay semi full all the time. The
dealers wouldn’t have room for the gas coming from the huge tank farms. The
tank farms wouldn’t have room for the gas coming from the refining plants.
And the refining plants wouldn’t have room for the oil being off loaded from
the huge tankers coming from the oil fields.

Just $10.00 each time you buy gas. Don’t fill it up. You may have to stop
for gas twice a week but, the price should come down.

Think about it.

As an added note…When I buy $10.00 worth of gas that leaves my tank a
little under quarter full. The way prices are jumping around, you can buy
gas for $2.65 a gallon and then the next morning it can be $2.15. If you
have your tank full of $2.65 gas you don’t have room for the $2.15 gas. You
might not understand the economics of only buying two eggs at a time but,
you can’t buy cheaper gas if your tank is full of the high priced stuff.

Also, don’t buy anything else at the gas station; don’t give them any more
of your hard earned money than what you spend on gas, until the prices come
down…” just think of this concept for a while.
