Installing Asterisk on CentOS

Installing CentOS for Asterisk this is Based on CentOS 4.1 for i386

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

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”***

Install prereqs:

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

#installing/upgrading asterisk
#clean modules - just in case this is an upgrade.
rm -f /usr/lib/asterisk/modules/*

Go fetch latest asterisk sources.

/usr/src

wget http://ftp.digium.com/pub/asterisk/asterisk-1.4.4.tar.gz
tar -zxvf asterisk-1.4.4.tar.gz
ln -s asterisk-1.4.4 asterisk

cd /usr/src/zaptel
./configure
# make menuselect

What are the different kinds of guitars?

An Introduction

The guitar is one of the most popular musical instruments today. There are different kinds of guitars that are available out there for different guitar players. Guitars are different in terms of playability, overall appearance and sound quality.

Here are some of the types of guitars that guitar players or aspiring guitar players can choose from:

Acoustic

If one wants go get into the guitar world, you can start learning with an acoustic guitar.

Acoustic guitars are dependent on their structures and body shapes in resonating sounds. Unlike the more modern electric guitars, they don’t rely on other external devices in making sounds. The natural vibrations of the strings are resonated by the body of the guitar.

Acoustic guitars are generally made out of wood. The neck is usually made from mahogany and the fret board is made out of maple or rosewood. There are many kinds of acoustic guitars, here are some of them:

1) Classical

Classical guitars are very popular. They are usually the choice guitar for beginners. The strings are usually made from nylon. These are usually played in a standard sitting position and used in playing classical music. Classical guitars produce think and whole sounds which are very warm to the ears.

Flamenco guitars are almost similar to the classical guitars; however, these guitars produce crisper and thinner sounds than the classical ones.

2) Steel-top

Steel-top guitars are much similar to the classical guitar. These, however, are constructed to be more resilient. The parts of the steel-top

guitar are reinforced and their bodies are significantly larger than the classical guitars. They produce a warmer tone than the classical guitar.

3) 12-String guitar

A normal guitar usually has 6 strings, but the 12-string guitar, as its name implies, has 12 strings. Each string is accompanied by another string with the same note but is usually tuned in a higher octave. This kind of guitar produces a semi-chorus effect which is very pleasant to the ears.

4) Resonator

This type of guitar is similar to the steel-top guitar, but the steel in the middle of the soundboard is used to resonate the sound from the vibration of the guitar strings. This produces a very thin and distinct sound. These guitars are usually used in playing the blues. There are also variations of the resonator guitar; the square-neck resonator guitar is played on the lap like a piano or organ. The round neck resonator guitar is played like a common guitar. Resonator guitars work very well with glass or metal slides.

5) Archtop

The archtop guitar is inspired by other instruments such as the violin and the cello. An archtop guitar usually has the f-hole design. Jazz players prefer archtop guitars. Some archtop guitars can reach prices of about $25,000 USD.

6) Acoustic Bass

Acoustic bass guitars are bass guitars without electronic pick-ups. The body of the guitar is used to produce the sounds. These are usually 4-stringed guitars but there are acoustic bass guitars which have 5 or 6 strings.

Electric

Electric guitars make use of electronic pick-ups to amplify the vibrations of the guitar strings. They are usually connected to electric amplifiers. Electric guitars usually have a solid or semi-solid body type. They don’t use the body for sound resonance and thus, they usually make very little or no sound when played without an amplifier. The concept used by electric guitars is- the energy of the strings are diverted into

electrical impulses are not directly into sound to be able to achieve an amplified sound.

Electric guitars usually have control knobs for changing the volume or the tone of the guitar. There are also pick-up selectors in electric guitars. Many electric guitars use multiple pick-ups to achieve the best guitar sounds. These pick-ups gather and produce different tones from the guitar. The tone knobs are usually used to shift from a bass-intensive sound to a treble-intensive sound or vice versa.

Some electric guitars also have whammy bars. These bars are attached to the guitar to shift notes without changing the finger positions in the fret board. Whammy bars are used to produce “crying” guitar sounds. This is a very useful tool in doing rock and roll songs or even ballads. The use of the whammy bar in less expensive guitars is not advised because it may cause the strings to go out of tune.

These are some of the basic types of guitars that are available out there for everyone. Guitars are made to fit into the preferences of the player in terms of playability and sound. Choose the guitar that best fit your preferences.

How to Kill a Dragon

Today I was appoint for a meeting in Sir Syed University with my Boss. This meeting was very food-full. And i got very useful points. We were also talked on this topic that why students are not involved in professional field and why they don’t do job related to their degree, Well it was a very big meeting, and I don’t have time to post all thing about the meeting, We also met with the Chairman of University, he is a very nice person, he told us a story, I just catch it and I liked it also. The title of that story was “How to kill a dragon” it was related to our topic.

A man wants to learn that how to kill a dragon and he spend his lots of money and lots of time to learn this, at-last he learned that how to kill a dragon.

Now he go to search a dragon for practical, and now he spend a lots of time again to search a dragon but he didn’t find :( . After that he also starts teaching that How to kill a dragon :D .

After listen this and so much thinking on this story i got just one point that if you can’t do anything just start teaching. Sorry to all teachers but it’s true now everyone is becoming a teacher and we students are unable to learn best. But I love my college TEC now the new teachers are so so but I can’t forget some of my teachers, Specially Miss Amber and Miss Sophia. In my life I have a great experience of learning and I am feeling myself very lucky that my teachers are Great.

But the reason of this posting is that I want to know your opinion about your teachers, and If you have good advice for me to change my thinking about that If you can’t to anything start teaching.
