Rsnapshot is a backup solution for Unix machines including Linux and OSX, it supports many great features including full backups with the size of only incremental backup, it also support backing up local and remote machines.

When I started producing backup worthy files (code, documents, projects, etc …), I realised the importance of backups after losing important files which happens to everybody. So I started my journey with backup solutions.

Backup generation 1: My first backup was simple directory copy operation, I copied my important directories to external floppy (then CD), and since it is manual operation I always forget about it and my backups was always old.

I love phpmyadmin, it is a web interface for MySQL DB server, I usually use the English interface, but the problem with English interface that it doesn’t show Arabic string, of course you can change the whole interface to Arabic, but I don’t understand anything from that interface.

So I played with PHPMyAdmin code so I can use English interface but using Arabic character set, here is how to do it:

# vi lang/english-iso-8859-1.inc.php
... change: $charset = 'iso-8859-1';
... to: $charset = 'windows-1256';


If you have a long running job that leaks few bytes of memory it will eventually will consume all of your memory with time.

Django is a web framework written in Python language, my favourite computer programming language.

Python a language is really great language, easy to read and understand, and very easy to learn, but for me I always found setting up Python for web development as a challenge, socially if compare it to PHP, which almost works out of the box, actually most people think PHP works only in the web server and can’t work as stand alone application, search for PHP CLI if you are interested.

I will try here to document an easy Django deployment for my future reference and hopefully it will help others:

لماذا لا تقوم بحجز اسم نطاق خاص بك مثل www.rr.sa ويكون عنوانك البريدي هو rayed@rr.sa، وبالمجان ايضاً.

I got a DNS failure when I tried to access my website yesterday, I didn’t suspect my ISP because I am using OpenDNS as my name server, so I switched back to SAUDI NET name servers and it worked fine. So I thought it was OpenDNS problem, until I read the news about large-scale DDoS attack on Network Solutions my DNS registrar, where I also host my DNS for rayed.com.

Setting up a Postgres replaication

If you to connect to PostgreSQL without typing a password, you can do it by having your password in the file “.pgpass”.

For each new project that need PostgreSQL you should create its own user and its own DB, the following are the steps need for that.

Installation

$ sudo aptitude install postgresql
$ sudo aptitude install python-psycopg2  # For Django access

Require a Password

$ sudo vi /etc/postgresql/9.1/main/pg_hba.conf
:
#local   all             all                      peer
local    all             all                      md5
:
$ sudo service postgresql restart    

Create Postgres User

$ sudo -u postgres createuser -P my_user
Enter password for new role: 
Enter it again: 
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) n
Shall the new role be allowed to create more new roles? (y/n) n

Create DB

$ sudo -u postgres createdb my_db -O my_user

Test It

$ psql -U my_user my_db   

After login you issue any SQL statement, you should also try the following commands:

Subject:	New Link Migration Plan
Date:	Wed, 10 Feb 1999 15:34:40 +0307

Salam Brothers,

As you all know KACST was connected through King Faisal Specializes
Hospital, and since KACST is now connected through ISU, we have to
replace our old IP addresses with the new ones from ISU.

Of course this will affect the leased-line link and E-Mail traffic with
all of you, and we tried to delay the migration as much as we can to
give you enough time to set up your own services through ISU link.

Our dead line to return the old IPs will end in less than a month, then
we have to return them to RIPE, we are going to start our plan to
migrate to the new IPs, and we have to stop the leased-line link and our
old mail relay that serve your domains when we return the old IPs.

I am sure that most of you are ready by now, but if you are facing any
problems we will be happy to help you with it.

NOTE:
Please send me the current state of your migration plan, and the
estimated time to finish.

One of the hosted projects is Quran project, they produced many XML files of Quran text, and they needed help with collecting data, both textual data, and audio data.
So I talked with Abdullah Aldosari about it, and it happened that he have MySQL table with this kind of data, so I processed the table and convert it UTF-8 to be complatible with ArabEyes and UNIX, my plan is to cleanup this data and contibue it back to ArabEyes.
Meanwhile I started playing with this data and created a web based Quran software, please try it out.

تحديث فبراير ٢٠٢٢ :

بعد تغيير سياسة Centos في التحديث، قررت التحويل الى ديبيان توزيعة ديبيان خفيفة ورشيقة مقارنة باوبنتو، ومجانية وتحديثاتها آمنة

تحديث ١٢ اكتوبر ٢٠١٨:

حولت بالكامل لسينوتس CentOS متوافق مع رد هات لكن مجاني.

تحديث ٢٩ اغسطس ٢٠١٣:

حاليا الخيار بالنسبة لي اوضح كثيرا، فهو ينحصر في اوبنتو Ubuntu خصوصا نسخة الخادمات، او سينتوس CentOS اذا احتجت توافقية مع RedHat.

الموضوع الاصلي

من اهم نقاط الضعف في نظام لينكس هي تعدد التوزيعات، مما يخلق حيرة في اختيار التوزيعة المناسبة حتى لدى خبرء يونكس، فعلى الرغم من اني مدمن انظمة يونكس منذ اكثر من عشر سنوات الا اني لا ازال احتار عند العمل مع لينكس، وهذه احد اهم الاسباب التي تجعلني افضل نظام فري بي اس دي (FreeBSD)، حيث لا يوجد سوى نظام تشغيل واحد فقط لا غير، واذا بحثت عن حل مشكلة في فري بي اس دي ستعرف انها سوف تعمل لانه لا يوجد سوى نظام واحد اسمه قري بي اس دي. طبعاً اذا اخترت توزيعة لينكس وبقيت عليها فانك تحصل على نفس الفائدة، لكن يبقى التشتيت مستمراً من قبل التوزيعات الثانية التي يظهر فيها مزايا جديدة من هنا وهناك.

The problem
In alriyadh.com most of the site administration take place inside the premises of Alriyadh Newspaper offices, and as you can image the bandwidth dedicated to the website team isn’t that big. This why we designed our system to have two parts, one inside Alriyadh Newspaper internal data center where the local access is very fast, and another part accessible to the public hosted in MeduNet, and we would have a database replication for the website data, and file system replication for the web site images and media.

IPv6 Technical Introduction

Getting IPv6 connectivity to your server isn’t very hard in fact if you have a decent provier you might already have it configured.

Do you have IPv6 already configured?

First try this command

$ ifconfig -a 

You will have result like this:

Mr. Latif Ladid, the president of IPv6 Forum, left a comment on a previous post on my blog with the latest update on IPv4 exhaustion, only 12% of IPv4 address are left, that is 2% in less than 3 months, the new estimate is 769 days.

This this insightful comment:

The IP address space is down to just 12% with 534 M IP addresses or 32 blocks left. see http://www.potaroo.net/tools/ipv4/index.html One of the most obvious and easily quantifiable incentives of the move to IPv6 is the growth and the continuity of the Internet and then the run to the bank for the remaining address space as it will be needed to have a secure dual stack transition which is the most secure transition and will be unfortunately the rich man’s transition. All others will tunnel which is not secure making it the poor man’s transition. Even the transition will aggravate the digital divide between the haves and have-nots in terms of security. The IPv6 Forum knew this problem 10 years ago and pushed ISPs to move earlier to manage a secure transition, but it takes patience and passion to make this happen.

I am currently preparing for Saudi Arabia IPv6 workshop, that we at CITC arranging at 8th of February 2009.

The workshop will have many high profile speakers in the IPv6 field.

You can find more information about the workshop at IPv6 website: www.ipv6.org.sa

Don’t forget to register for the workshop.

P.S. the website is built using Drupal

Only 14% of IP addresses are left, which is estimated to be used in 811 days which is around 2 years!!

Does that mean the Internet as we know it will stop growing? yes exactly, if we ran out of IP addresses you can not connect your new game console, phone, notebook, etc... to the Internet.

Scientists has found many solutions to delay this problem, including “classless network”, and NAT, which allowed us to use the IP address space more efficiently.

Just type:

sudo update-alternatives --config editor

So you managed to login to your Ubuntu Linux machine with a password by using the magic of ssh keys, and you installed “apticron” to email you whenever their is a system update, you login to the system and issue the update command “sudo aptitude update” and “sudo” asks you about your password! not only it is annoying, it also can’t be automated, imaging you manage 10 servers and you have to type the password to update each machine! or you want to automate using some remote execution application like Fabric or Salt (I am Python fan, so I won’t mention Chef or Puppet here).

Update: Django 1.6+ don’t need any of these steps! it will work out of the box.

The following is the shortest way to create DB backed Django project, it uses SQLite as a backend, which make the setup very easy and fast.

I usually use for testing new Django modules or apps.

**$ django-admin.py startproject mycms**
**$ cd mycms**
**mycms$ chmod +x manage.py **
**mycms$ vi mycms/settings.py **
import os

PROJECT_ROOT = os.path.abspath(os.path.dirname(__name__))

Last week my friend Osama Aldosary was cleaning his emails and found this 13 years old email from me back when I was working as a system admin at ISU KACST, and I was administrating the email servers that accept and forward all internet emails for Saudi universities, Osama was working for KSU back then.

Thank you Osama

Salam Brothers,

As you all know KACST was connected through King Faisal Specializes
Hospital, and since KACST is now connected through ISU, we have to
replace our old IP addresses with the new ones from ISU.

Of course this will affect the leased-line link and E-Mail traffic with
all of you, and we tried to delay the migration as much as we can to
give you enough time to set up your own services through ISU link.

Our dead line to return the old IPs will end in less than a month, then
we have to return them to RIPE, we are going to start our plan to
migrate to the new IPs, and we have to stop the leased-line link and our
old mail relay that serve your domains when we return the old IPs.

I am sure that most of you are ready by now, but if you are facing any
problems we will be happy to help you with it.

NOTE:
Please send me the current state of your migration plan, and the
estimated time to finish.

No surprise here. Life in the Saudi capital is not easy. “The possibility of a terrorist attack is an ongoing threat,” according to ORC, “while wide-ranging restrictions on dress, movement, conduct, food, alcohol, travel, and communications limit expatriate life.” The city is especially hard for foreign women. Finally, adds ORC, “violating the country’s strict moral religious codes is a particular danger in this conservative city.”

يوم امس دعاني جهاد العمار الى مؤتمر صحفي نظمة حول اطلاق النسخة الجديدة من موقع قيم، 50% من المؤتمر كان حول التطويرات الجديدة في الموقع والتي من اهمها اضافة خاصية الخرائط، فعلا رائعة!!! وكذلك اعلى مستخدمين (ترتيبي كان قليل 🙁 )

ما اثار اهتمامي اكثر هو الحضور، كان كثير ورائع، كمية الحماس والطاقة الموجودة كانت رائعة. لازم ابداء احضر مثل هذه الاجتماعات.

اذا كان لك اهتمام بالانترنت، والشبكات فيجب ان تحضر. هناك أكثر من عرض يجب على الجميع حضورها.

Mr. Latif Ladid, the president of IPv6 Forum, left a comment on a previous post on my blog with the latest update on IPv4 exhaustion, only 12% of IPv4 address are left, that is 2% in less than 3 months, the new estimate is 769 days.

This this insightful comment:

The IP address space is down to just 12% with 534 M IP addresses or 32 blocks left. see http://www.potaroo.net/tools/ipv4/index.html One of the most obvious and easily quantifiable incentives of the move to IPv6 is the growth and the continuity of the Internet and then the run to the bank for the remaining address space as it will be needed to have a secure dual stack transition which is the most secure transition and will be unfortunately the rich man’s transition. All others will tunnel which is not secure making it the poor man’s transition. Even the transition will aggravate the digital divide between the haves and have-nots in terms of security. The IPv6 Forum knew this problem 10 years ago and pushed ISPs to move earlier to manage a secure transition, but it takes patience and passion to make this happen.

احمد، جزاك الله خير، دائماً ما يثلج صدري بمقالتك.

Only 14% of IP addresses are left, which is estimated to be used in 811 days which is around 2 years!!

Does that mean the Internet as we know it will stop growing? yes exactly, if we ran out of IP addresses you can not connect your new game console, phone, notebook, etc... to the Internet.

Scientists has found many solutions to delay this problem, including “classless network”, and NAT, which allowed us to use the IP address space more efficiently.

In alriyadh.com most of the site administration take place inside the premises of Alriyadh Newspaper offices, and as you can image the bandwidth dedicated to the website team isn’t that big. This why we designed our system to have two parts, one inside Alriyadh Newspaper internal data center where the local access is very fast, and another part accessible to the public hosted in MeduNet, and we would have a database replication for the website data, and file system replication for the web site images and media.

If you are in the business of Internet operation, or have any interest in Internet at all, don’t miss the opportunity to attend.

This guide for my own reference please don’t rely on it, for a better introduction check out Git Reference website.

Basic concept and terminologies, Git have 3 logical places:

• Working Area: normal directory where you edit your project.
• Staging Area: Think of the staging as your project state before you start your coding session, after each coding session you add your changes to staging area using git add filename or git add .
• Snapshot Area: After multiple coding sessions you would finish a logical change, e.g. adding commenting system in web site, next you need to store a snapshot of your project after these changes, you would do that with git commit

Ericsson has successfully demonstrated data-transfer speeds of more than 500 megabits per second over copper, the communications company said Monday.

The data-transfer rates were achieved using a version of digital subscriber line (DSL) technology called “vectorized” VDSL2, Ericsson said in a statement. The technology, also called “crosstalk cancellation,” provides the high transmission rates through a twisted pair of copper cables by reducing the noise coming from other pairs in the same cable bundle. VDSL2 has traditionally offered speeds of around 100Mbps.

I got a DNS failure when I tried to access my website yesterday, I didn’t suspect my ISP because I am using OpenDNS as my name server, so I switched back to SAUDI NET name servers and it worked fine. So I thought it was OpenDNS problem, until I read the news about large-scale DDoS attack on Network Solutions my DNS registrar, where I also host my DNS for rayed.com.

Lately I am getting a lot of “Network Timeout” errors, is it my machine or does everybody get this error.

No surprise here. Life in the Saudi capital is not easy. “The possibility of a terrorist attack is an ongoing threat,” according to ORC, “while wide-ranging restrictions on dress, movement, conduct, food, alcohol, travel, and communications limit expatriate life.” The city is especially hard for foreign women. Finally, adds ORC, “violating the country’s strict moral religious codes is a particular danger in this conservative city.”

When Microsoft released Bing search engine, I was really impressed, it looks good and the search is good.

But unfortunately Microsoft have a very bad habits of ruining really good products.

When you try to search for Why is Windows so expensive?, the first result you will get is: “Why are Mac’s So Expensive?”
