Compiling Linux Kernel 3.8.x Vanilla Final - Ubuntu/Debian way

Here is my guide on Compiling 3.8.x Vanilla Final - Ubuntu/Debian using the Debian way

This article is about compiling a kernel on Ubuntu systems. It describes how to build a custom kernel using the latest unmodified kernel sources from www.kernel.org (vanilla kernel) so that you are independent from the kernels supplied by your distribution.
Install the Required packages for building it

 
apt-get install git-core kernel-package fakeroot build-essential ncurses-dev

Then download latest kernel version

cd /usr/src

sudo su 
wget --continue http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.8.x.tar.bz2
tar jxvf linux-3.8.*.tar.bz2
cd linux-3.8.*

$ cp /boot/config-`uname -r` ./.config
$ make menuconfig

Disable xen
Processor Type and Features -> Paravirtualized Guest Support -> Xen

support otherwise you will get this error

make-kpkg clean
fakeroot make-kpkg --initrd --append-to-version=-vanillaice kernel_image kernel_headers
cd ..
dpkg -i linux-image-3.8.*

dpkg -i linux-headers-3.8.*
sudo shutdown -r now

you can install the headers too from /usr/src/linux-headers-3.7.*-*
in my case i can show you how the packages are named

ls *.deb
linux-image-3.8.*-vanillaice_4.4.*-vanillaice-10.00.Custom_amd64.deb
linux-headers-3.8.*-vanillaice_4.4.*-vanillaice-10.00.Custom_amd64.deb

I also created a python script http://github.com/mariuz/kernelcompile

that can be used like this

git clone https://mariuz@github.com/mariuz/kernelcompile.git

cd kernelcompile
sudo ./kernel-compile.py

What to choose from fourth Firebird Architectures :SuperServer , Classic , SuperClassic or Embedded?

There are some papers around that explain what are the differences : SuperClassic Presentation from one of the main core developers http://www.slideshare.net/ibsurgeon/firebird-25-architecture-by-dmitry-yemanov-in-english
and the Classic vs SuperServer question in the Getting Started guide for Firebird 2.5.x

or another one that i like is this blog post with nice pictures of the three architectures: Super , Classic and SuperClassic http://www.sinatica.com/blog/en/index.php/articles/firebird-superserver-classicserver-or-superclassic

The fourth Architecture is Embedded and that is entire server contained into one dll on windows or so file on linux that can be used without a tcp/local connection and it will access your database file directly

Thomas created a compact architecture comparison sheet, which is available here

Adobe Photoshop 1.0 Source Code About 75% is in Pascal

You can read the full article on http://www.computerhistory.org/atchm/adobe-photoshop-source-code/

What i loved was the part about the Efficency and Productivity for Pascal Language , compare that with our days when you need large teams for large and ineficcient java EE projects







That first version of Photoshop was written primarily in Pascal for the Apple Macintosh, with some machine language for the underlying Motorola 68000 microprocessor where execution efficiency was important. It wasn’t the effort of a huge team. Thomas said, “For version 1, I was the only engineer, and for version 2, we had two engineers.”

With the permission of Adobe Systems Inc., the Computer History Museum is pleased to make available, for non-commercial use, the source code to the 1990 version 1.0.1 of Photoshop. All the code is here with the exception of the MacApp applications library that was licensed from Apple. There are 179 files in the zipped folder, comprising about 128,000 lines of mostly uncommented but well-structured code. By line count, about 75% of the code is in Pascal, about 15% is in 68000 assembler language, and the rest is data of various sorts. To download the code you must agree to the terms of the license.

Download Photoshop version 1.0.1 Source Code

Lazarus Free Pascal IDE 1.0.6 Final release is available for download , here is howto install it on #Ubuntu 12.04/12.10 or #Debian

The Lazarus Free Pascal IDE team is glad to announce that Lazarus 1.0.6 is available for download on sourceforge net download area

Check your cpu if is x86-64/32

open console and type

uname -m
x86_64

That means you need 64 bit version that means AMD64 (x86-64 instruction set was invented by AMD and this is why is called this way but all you need to know is AMD64=INTEL64=x64=x86_64 and even if is named that way it will work on all x64 cpus : INTEL, AMD, VIA)

Go to the sourceforge download page
Choose Lazarus Linux amd64 DEB then Lazarus 1.0.6

From that dir you need to install in order :fpc , fpc-src and lazarus


if

uname -m
i686

that means 32 bit version i386 again for all CPUS  INTEL, AMD, VIA


Choose Lazarus Linux i386 DEB then Lazarus 1.0.4

From that dir you need to install in order :fpc , fpc-src and lazarus

ps:why is called i386?

because i386 was the first x86-32 cpu  also this is how debian calls the 32bit port

If you are using fpc deb from lazarus download area on debian or ubuntu and want to pin it from upgrades here is how : 

echo fpc hold  | sudo dpkg --set-selections

One way to Scale UP Firebird :put you Database on memory virtual disk or ramfs

There is a new ec2 type of instance with huge memory option : 244G
http://aws.typepad.com/aws/2013/01/ec2-for-in-memory-computing-the-high-memory-cluster-eight-extra-large.html

How this can help you with scaling Firebird ?

There are the cache and memory settings For Firebird but is better to put the main full database on the fastest storage and that is RAM for the moment

On linux i can mount a partition in memory (Install ubuntu/debian)

sudo mkdir /mnt/ram
sudo mount -t ramfs -o size=200G ramfs /mnt/ram
mount to show you the partitions mounted

and then move your database into the ram partition

cp -rp /var/lib/firebird/2.5/data/slowdb.fdb /mnt/ram/fast.db


What about D from the ACID ?

In Firebird we have a nifty feature called Shadow that creates a life snapshots of the active database (Think of it as Replication in real time) so you can activate it and keep a safe database on the SSD/HDD

http://ibexpert.net/ibe/index.php?n=Doc.DatabaseShadow




That large instance could help you with the Firebird cache settings also the extra SSD could do wonders
Inspired by the stack overflow big fat server architecture for the SQL

Debian is used by 32.8% of all the websites who use Linux on January and growing

Debian is used by 32.8% of all the websites who use Linux on January w3techs stats report and growing . RedHat Linux is going bellow 10% ,I f you still deploy Redhat and CentOS on servers think twice they are on he death spiral on the server side usage

This is why recommend Debian instead of Ubuntu

Ubuntu provides specific repositories of nonfree software, and Canonical expressly promotes and recommends nonfree software under the Ubuntu name in some of their distribution channels. Ubuntu offers the option to install only free packages, which means it also offers the option to install nonfree packages too. In addition, the version of Linux, the kernel, included in Ubuntu contains firmware blobs.


Ubuntu's trademark policy prohibits commercial redistribution of exact copies of Ubuntu, denying an important freedom.


As of October 2012, Ubuntu sends personal data about users' searches to a server belonging to Canonical, which sends back ads to buy things from Amazon. This does not, strictly speaking, affect whether Ubuntu is free software, but it is a violation of users' privacy. It also encourages buying from Amazon, a company associated with DRM as well as mistreatment of workers, authors and publishers.


This adware is one of the rare occasions in which a free software developer persists in keeping a malicious feature in its version of a program.
