APT Packaging Management Tool In Detail; Linux
January 07, 2015, 01:23:26 pm by MohdSohail
A package is a 'Software'. Examples of the package can be the browsers (Google chrome, Mozilla, Safari etc.), utilities package (ccleaner, ASC, BleachBit etc.), designing program (Photoshop, Gimp etc.) and Games (Need for Speed, Call of Duty etc.). The packages/software are compiled and set altogether so that when someone executes them, all the files or scripts start and install the programs on the system. Sometimes the compiled code is provided in which everything is setup, all the files and scripts, only thing user do is execute them. Mostly programs are packaged so that user can easily install it.
That packaged code need to be unpackaged or execute through 'Package Management Tools'. That's where newbies have problem/confusion in Linux.
While turning from Windows/Mac to Linux, one of the biggest problems is to understand the packaging management tools in Linux. The first confusion understanding software installation is different types of packaging tools for different Linux distributions and second is in Windows we've simply a setup.exe file clicking on which starts the installation. In Linux also we've such files to install programs but they get changed in other Linux Distributions.
Although Windows packaging setup.exe has also some problems, like, they are larger in size and some others but I am discussing here about packaging In Linux, APT. So let's get started.
In this Article I am only heading to APT. To see other packaging Management tools, just see my article How To Install Software In Linux : An Introduction
Introduction to APT
As I mentioned above for different distributions we've different packaging management tools and so APT is for the Linux Debian based distributions. APT stands for Advanced Package Tool. In the beginning the .tar.gz (source code) was given that users had to compile them before they install on their GNU/Linux system. When the debian was created then they thought to make change and they designed a packaging management/system called dpkg. Then Red Hat after a while created rpm system. Then there was another challenge to install those packages easily and efficiently on systems with configuring perfectly and manage dependencies automatically. Then Debian created APT, Advanced Packaging Tool, since then has been being used in several other Linux distributions.
It was all needed to know for understanding the basics of the packaging and packaging management tools. Keep in mind the packaging management tools are the tools to execute programs in different ways. Here I'm going to tell you that how you can install/Unpack/configure any software (i.e package) through a widely used tool APT. It's all done in terminal, don't get scared it is super easy! And yeh! It can also remove/uninstall, update and upgrade any packages from the system as well. So It's very featured.
How to use APT to install software : Commands
Each command needs user to be in root or using sudo.
APT commands have been better described on the website in article APT Packaging Management Tool In Detail; Linux

How To Install Software In Linux : An Introduction
In any operating system we need to install applications to complete our day to day tasks. In the world of Windows, every program has a simple Setup.exe or a program.zip file. On a Mac a package is a program.dmg or a program.sit file. In both the operating system you can simply click it and it will ask you some very basic configuration questions like, do you accept the licence agreement or the directory you want to install the software to. Although in Linux, It seems tough to install the programs/softwares but It's not true.
It's as simple as in the two OS I mentioned above. There are sometimes problems with some type of files that you have to fight tooth and nail, here I'll not cover those specifically, but will cover them giving basics of installing software that will help finding rough spots easy.
Software Package in Linux
As I mentioned above Windows has setup.exe or program.zip file and Mac has program.dmg or program.sit file, they are actually packages. Every software comes in “packages”. In the same way in Linux, there are several types of packages, and every distribution has its own preferred package format. It means there are more packages in Linux than any other OS.
According to the Linux Standerd Base the standerd Linux package is RPM. RPM stands for Red-hat Package Manager, orginally devoloped by Red Hat and widely used by the Linux community. Red Hat, Fedora, Mandriva and SUSE use the RPM. The RPM file looks like this program-version-other.rpm
The second package manager format is DEB, stands for Debian. Debian packages and the APT (Advanced Packagin Tool) has made advanced features that are now commonly used, like, automatic dependency resolution and signed packages. Debian packages are used by Debian/Linux, and some of the most used Linux distributions, like, Ubuntu, Linux Mint, Mepis etc. The .deb/Debian files look like this program-version-other.deb
APT For Debian based distributions, like, Ubuntu, Linux Mint etc.
The APT is the tool, commonly used to install packages, remotely from the software repository. In short it's a simple command based tool that you use to install files/softwares. Complete command is apt-get and it's the easiest way to install files/Softwares packages. This easy tools informs you about packages that are currently being installed and also it informs you about the packages that are available in repositories.

How To Install/Upgrade To Linux Kernel 3.18.1 In Ubuntu/Linux Mint or other distributions
Recently in December Linux Kernel version 3.18.1 has been released and announced by Linus Torvalds. If you are using Ubuntu 14.04/14.10 or Linux Mint or any other debian/Ubuntu based then you can update to the latest kernel 3.18.1 to fix bugs, increase performance and security of the system.
What Is Linux Kernel?
Those who don't know what is the Linux Kernel they should know it because Linux kernel is the essential part of any Linux operating system. It is responsible for resource allocation, low-level hardware interfaces, security, simple communications, basic file system management, and more. Written from scratch by Linus Torvalds (with help from various developers), Linux is a clone of the UNIX operating system. It is geared towards POSIX and Single UNIX Specification compliances.
Install Linux Kernel 3.18.1
Because it is not available via PPA, the needed deb packages of Kernel 3.18.1 are available via kernel.ubuntu.com. Follow the instructions for your system’s architecture exactly, in order to get a successful installation. Read more How To Install/Upgrade To Linux Kernel 3.18.1 In Ubuntu/Linux Mintntu/Linux Mint

Computer geek jokes
August 20, 2013, 12:31:14 am by Melissa
Have a laugh and see if you can add your own.
A doctor, a civil engineer and a programmer are discussing whose profession is the oldest.
“Surely medicine is the oldest profession,” says the doctor. “God took a rib from Adam and created Eve and if this isn’t medicine I’ll be…”
The civil engineer breaks in:
“But before that He created the heavens and the earth from chaos. Now that’s civil engineering to me.”
The programmer thinks a bit and then says:
“And who do you think created chaos?”
In the beginning, God created the bit. And the bit was a zero; nothing.
On the first day, He toggled the 0 to 1, and the Universe was. (In those days, bootstrap loaders were simple, and "active low" signals didn't yet exist.)
On the second day, God's boss wanted a demo, and tried to read the bit. This being volatile memory, the bit reverted to a 0. And the universe wasn't. God learned the importance of backups and memory refresh, and spent the rest of the day ( and his first all-nighter ) reconstructing the universe.
On the third day, the bit cried "Oh, Lord! If you exist, give me a sign!" And God created rev 2.0 of the bit, even better than the original prototype. Those in Universe Marketing immediately realized the the "new and improved" wouldn't do justice to such a grand and glorious creation. And so it was dubbed the Most Significant Bit, or the Sign bit. Many bits followed, but only one was so honored.
On the fourth day, God created a simple ALU with 'add' and 'logical shift' instructions. And the original bit discovered that by performing a single shift instruction, it could become the Most Significant Bit. And God realized the importance of computer security.
On the fifth day, God created the first mid-life kicker, rev 2.0 of the ALU, with wonderful features, and said "Screw that add and shift stuff. Go forth and multiply." And God saw that it was good.
On the sixth day, God got a bit overconfident, and invented pipelines, register hazards, optimizing compilers, crosstalk, restartable instructions, microinterrupts, race conditions, and propagation delays. Historians have used this to convincingly argue that the sixth day must have been a Monday.
On the seventh day, an engineering change introduced UNIX into the Universe, and it hasn't worked right since.
Obviously a heathen or Microsh**t worshipper.
