Jesus is Risen – Truly he is Risen / Hristos Voskrese paschal greeting and why Orthodox Christians don’t celebrate with Roman Catholics and Jewish

Jesus Glorious Resurrection from the grave in the third day Orthodox Christian Icon

It is the first week after Orthodox Christian Easter. This year 2012, the Orthodox Christians Easter date was on fifteen of April.
We've not just had a feast of an Eastern, but we actually celebrated the greatest day in all human history that happened 2012 years ago – The Glories Resurrection of our Lord Jesus Christ from the Death in the Third day!

Some Roman Catholic Christians, might be wondering, why the Orthodox Church is celebrating one week after Jewish Pascha, so in short I will explain in the reason.We orthodox christians do not celebrate with Roman Catholics Easter because Roman Catholics use the gregorian calendar to calculate and decided the day in which the Eastern celebrations should occur, where we the Orthodox Christians use still the old moon calendar (which the jews used too), when Jesus was crucified.
The gregorian calendar is very precise from a scientific point of view, however from a Church stand point it is completely wrong because, plainly taking the gregorian calendar math model doesn't take in consideration, that the jews are still celebrating their pascha following the old moon calendar.

The consequence is this year Roman Catholics, celebrated with Jewish. This from our Orthodox Christian point of view is incorrect, because Christ's Cross suffering is the pascha for us christians.
We Christians consider that the old God ordained jewish pascha was a prophecy feast, simply to remind jewish people before Christ's coming that Messiah (Christ) will come to say his people.
As Jewish rejected their true Messiah and Crucified him on the Cross, they have rejected to accept Christ as being the true pascha lamb slained for our sins.

Hence the Orthodox Christian Church teaches even to this day, that it is not righteous to celebrate Christ's Glorious Resurrection with Jewish Pascha.
Prohibition to celebrate Easter and Jewish Pascha on the same day is an Orthodox Church rule, since the early church days.
The Holy Fathers in their Church councils Council of Nicaea etc. has established as unchangable Church rule that, Jesus's Resurrection day feath, should never-ever coincide with the Jewish Pascha Celebrations.

The reasons the Church fathers ordered the Church Easter day to be always 1 week after Jewish Pascha is our saviour Jesus Christ ate pascha with his desciples as we can read in the 4 gospels in Holy Bible. After Jesus ate pascha, he was caught mocked, tortured and crucified (killed on a cross shaped trees).

Jesus is Risen! Truly He is Risen!

The Slavonic Paschal Greeting, translated words, we use across the Slavonic dome: ( Bulgaria / Russia / Ukraine, Serbia) is:

Христос Воскресе ! Воистину Воскресе!

According to our Church Tradition, Christians should great each other with the Paschal greeting Hristos Voskrese during the whole "bright week" instead of the usual Hi / Hello phrase.

The current Bulgarian version of Христос Възкресе ! Воистину Воскресе! is

Христос Възкръсна! Наистина Възкръсна!


One great miracle that testifies about the Christ's resurrection each and every year happens on each Orthodox Christian Eastern in Jerusalem in the Temple of Holy Sepulchre (where the saviour's grave cave, before the resurrection used to be). Last year, I've written to great all Christians for the Resurrection with the joyful Paschal Greeting Jesus is Risen and the Miracle of the Holy Fire
Pitily, the number of Roman Catholics who heard or know about this amazing miracle are mostly within the clergy. Its very rare a layman Christian in Roman Catholic realm heard of the miracle. Once again as a closure I want to great everyone with the joyful paschal greeting in the manners of Russians which say it three times during the paschal period.

Христос Воскресе! Воистину Воскресе !
Христос Воскресе! Воистину Воскресе !
Христос Воскресе! Воистину Воскресе !

How to get rid of “PHP Warning: PHP Startup: Unable to load dynamic library ‘/usr/lib/php5/20090626/'” on Debian GNU / Linux

Tuesday, October 25th, 2011

Reading Time: 2minutes


After a recent new Debian Squeeze Apache+PHP server install and moving a website from another server host running on CentOS 5.7 Linux server, some of the PHP scripts running via crontab started displaying the following annoying PHP Warnings :

debian:~# php /home/website/www/cron/update.php

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626/' – /usr/lib/php5/20090626/ cannot open shared object file: No such file or directory in Unknown on line 0

Obviously the error revealed that PHP cli is not happy that, I've previously removes the suhosin php5-suhosin module from the system.
I wouldn't have removed php5-suhosin if sometimes it doesn't produced some odd experiences with the Apache webserver.
To fix the PHP Warning, I used first grep to see, where exactly the suhosin module gets included in debian's php.ini config files. debian:~# cd /etc/php5
debian:/etc/php5# grep -rli suhosin *

Yeah that's right Debian has three php.ini php config files. One for the php cli/usr/bin/php, another for the Apache webserver loaded php library/usr/lib/apache2/modules/ and one for Apache's cgi module/usr/lib/apache2/modules/ .

I was too lazy to edit all the above found declarations trying to include the suhosin module in PHP, hence I remembered that probably all this obsolete suhosin module declaration are still present because probably the php5-suhosin package is still not purged from the system.

A quick check with dpkg , further strenthened my assumption as the php5-suhosin module was still hanging around as an (rc – remove candidate);

debian:~# dpkg -l |grep -i suhosin
rc php5-suhosin advanced protection module for php5

Hence to remove the obsolete package config and directories completely out of the system and hence solve the PHP Warning I used dpkg –purge, like so:

debian:~# dpkg --purge php5-suhosin
(Reading database ... 76048 files and directories currently installed.)
Removing php5-suhosin ...
Purging configuration files for php5-suhosin ...
Processing triggers for libapache2-mod-php5 ...
Reloading web server config: apache2.

Further on to make sure the PHP Warning is solved I did the cron php script another go and it produced no longer errors:

debian:~# php /home/website/www/cron/update.php

A Hunting Accident is another one of those many Classic Soviet Movies. It is produced in 1978. As most Russian movies you have to be russian to understand it 🙂 The movie doesn't have a too special plot but has unique scenes very much reminding me of Gothism. Its really worthy to see the movie just for the sake of getting to know better Soviet Culture. White Horses beautiful ladies, elegant gentleman in white carrets this is the accident of the movie. The main actress is stunningly beautiful just like most Russian ladies 🙂
Movie is a great one for people who value Art movies.

12 Lessons Steve Jobs Taught Guy Kawasaki – SEO Summit Guy Kawasaki speech

Monday, July 30th, 2012

Reading Time: 2minutes

I'm not a big fan of Steve Jobs, neither I like the cult that is nowdays to his personality. After his recent death the cult to Jobs and his works has bloomed once again. From philosophical point of view I don't like Jobs ideas that there is no good and bad but only success matters. However I should admit as a SEO and as a business enterpreneur his achievements are significant. Hence I decided to share with you a video of SEO Summit ex-employee Guy Kawasaki, who "worked for jobs twice and survived". Jobs is famous for not being loved too much by his employees. Also it is not a secret historically he screw up, Steve Wozniak and a number of other people who were either employeed or worked in any way with him.

The points his ex-employee KAWASAKI shares on this SEO Summit presentation are quite interesting and are things, beginning business enterpreneurs like me could learn tremendously from. One key point that is hardly underlined in the presentation is the importance of simplicity.

* Simplicity in everything is essential for the success. It was quite curious to me Steve Jobs presentations were consisting often with a slides of just one word. Obviously this means Jobs was a simplicity freak.

Some of other concepts of Jobs was:

Either it works or it doesn't work.

You see again his trend to be simplifying things. In business we all know the SMART (Keep it Simple And Stupid). It seems Jobs SMART was only SAS (Simple and Stupid) 🙂 ….

Some other things Kawasaki learned from Jobs was:

Never believe Experts

– If someone tells you he is an expert in something he is definitely not ….

Another belief (understanding) of Jobs and probably many other succesful enterpreneurs is that DESIGN COUNTS. Design is one of the most crucial points in any product, so one has to be extra-careful here. A fail in design is a fail in product line ….

There is plenty of other interesting stuff in the video but the key point is SIMPLICITY. Enjoy Kawasaki Speech …

Drawing GANTT Charts and Project Management on Linux, (Microsoft Project substitute for Unix)

Tuesday, October 12th, 2010

Reading Time: 3minutes

I'm studying Project Management, right now. In that spirit of thoughts I and a couple of other guys are building a Project Plan.
As it Project Plan it's necessary to put a GANTT Chart in it to show visually the project timeline (the phases), the duration and the inter-relation between the different tasks which leads the project to an actual completion.

After a bit of thorough research online on available software to deal with project management and particularly, ones that are capable to build a GANTT charts on Linux / BSD.

I've come with the following list of software capable to be a substitute for the Microsoft Project software.
Redmine GANTT Chart

GANTT chart Redmine

1. Gantt Project
GANTTProject chartGANTTProject Chart

2. Gnome Planner
Planner GANTT Gnome ChartPlanner GANTT Chone Chart

3. Task Juggler Project Manager with GANTT Capability for (KDE)
Task Juggler

4. JxProject – This software is not free, though it can be considered almost free
Take a look also at:
5. Trac , though it doesn't really support GANTT charts it's a lovely software to be used for PM.
Trac Project Management

Another option you have is to try out:
6. PHProjekt

Update 20.09.2016 – PHPProject Old download link is no longer active

It is this link, but the page doesn’t seem to be active any more. I thought you might want to update.

If you are looking for an alternative please check out, it may make a suitable replacement.

Kind Regards,
Tom Wilcox

That piece of softwre really looks promising, especially if we consider that it's web based and how much essential is today to have an anline tools for doing the ordinary desktop jobs.

You can even check an online demo of the PHPProjekt software here

If you're a type of KDE user you definitely has to try out Kplato

As I've tested the software the software is easy to be used, however it still is missing some essential parts that Microsoft Project includes so it's not 100% substitute.
Also it's not able to open Microsoft Project (MPP) files, neither able to save the charts in the .mpp format.

Moving ahead I've came across DotProjectDotProject Gantt Chart
DottProject Gantt Chart

I haven't took the time to test it myself but however, as I go through the software website the project looked quite good.
Lastly you can take a look at: 7. PStricks as a mean of project management, however I think it doesn't support GANTT chart building.

Windows XP multicore not detected after CPU update – XP Enable multicore after singlecore install

Friday, April 8th, 2016

Reading Time: 3minutes

These days it is not common to install Windows XP however for some old unsupproted applications that still work on XP in many countries  in Africa, Asia, Europe and even America. Custom patched Windows XP is still heaveily used for some corporate businesses in accounting and on airports and other government institutions even to these day, I'm aware of Windows still heavily used especially in  Russia, Belarus,Ukraine, Kazakhstan, Armenia, Bulgaria etc.

Hence still there is plenty of softwares designed to work XP the good old Win XP and thus often XP needs to be emulated on VMs though officially not supported any longer  by Microsoft (its Support lifecycle End was for a last time on April 14, 2009).

Now I guess these days I guess nobody doesn't install and use Windows XP on a normal hardware PC Desktop / laptop but XP is continually installed on Virtual machine servers VMWare / VirtualBox.

Hence if you happen to have already migrated or installed some old Windows XP operating systems under VMWare for a corporate clients single core machine (no matter virtual or physical) and the client requires an update of hardware of the Virtual Machine you will be surprised that even though you add a second / third etc. core (new CPUs) the virtual machine hardware and restart the Windows XP installation.

It seems XP is designed to remember the install time CPU model hardware so once the VM and doesn't have a way to update its HAL (Hardware Abstraction Layer) definitions if you install it in Virtualbox thus to make XP recognize the extra added CPU cores it is necessery to do a small hack with a devcon.exe utility downloadable from Microsoft site to do the trick

1. Download the command line devicemanager utility (devcon.exe) from Microsoft Development Network MSDN here.

Note that it will work only if you use the correct version depending whether XP is  (x86/x64) bit install so check it out from My Computer -> Properties.


2  Next. Execute the following 2 commands:

    devcon sethwid @ROOT\ACPI_HAL\0000 := +acpiapic_mp !acpiapic_up
    devcon update c:\windows\inf\hal.inf acpiapic_mp

devcon.exe will  let the automatic hardware detection find out the extra CPU (multicores) added.
Wait 'till you get prompted for a reboot.
Be brave Reboot! 🙂

There is pretty much more fun useful things you can do with devcon.exe such as disabling USBs from command line,


listing your PCI devices and so on:


You should now see all cores, hooray cores will appear in Task Manager / System Information.

How to check Apache Webserver and MySQL server uptime – Check uptime of a running daemon with PS (process) command

Tuesday, March 10th, 2015

Reading Time: 2minutes


Something very useful that most Apache LAMP (Linux Apache MySQL PHP) admins should know is how to check Apache Webserver uptime and MySQL server running (uptime).
Checking Apache / MySQL uptime is primary useful for scripting purposes – creating auto Apache / MySQL service restart scripts, or just as a quick console way to check what is the status and uptime of Webserver / SQL.

My experience as a sysadmin shows that lack of Periodic Apache and MySQL restart every week or every month often creates sys-admin a lot of a headaches cause (Apache / NGINX / SQL  server) starts eating too much memory or under some circumstances leads to service or system crashes. Periodic system main services restart is especially helpful in case if Website's backend programming code is writetn in a bad and buggy uneffient way by unprofessional (novice) programmers.
While I was still working as Senior SysAdmin in Design.BG, I've encountered many such Crappy Web applications developed by dozen of different programmers (because company's programmers changed too frequently and many of the hired Web Developers ,were still learning to program, I guess same is true also for other Start-UP Web / IT Company where crappy programming code is developed you will certainly need to keep an eye on Apache / MYSQL uptime.  If that's the case below 2 quick one liners with PS command will help you keep an eye on Apache / MYSQL uptime


ps -eo "%U %c %t"| grep apache2 | grep -v grep|grep root
root     apache2            02:30:05

Note that above example is Debian specific on RPM based distributions you will have to grep for httpd instead of apache2

ps -eo "%U %c %t"| grep http| grep -v grep|grep root

root     apache2            10:30:05

To check MySQL uptine:

ps -eo "%U %c %t"| grep mysqld
root     mysqld_safe        20:42:53
mysql    mysqld             20:42:53

Though example is for mysql and Apache you can easily use ps cmd in same way to check any other Linux service uptime such as Java / Qmail / PostgreSQL / Postfix etc.

ps -eo "%U %c %t"|grep qmail
qmails   qmail-send      19-01:10:48
qmaill   multilog        19-01:10:48
qmaill   multilog        19-01:10:48
qmaill   multilog        19-01:10:48
root     qmail-lspawn    19-01:10:48
qmailr   qmail-rspawn    19-01:10:48
qmailq   qmail-clean     19-01:10:48
qmails   qmail-todo      19-01:10:48
qmailq   qmail-clean     19-01:10:48
qmaill   multilog        40-18:02:53


 ps -eo "%U %c %t"|grep -i nginx|grep -v root|uniq
nobody   nginx           55-01:22:44


ps -eo "%U %c %t"|grep -i java|grep -v root |uniq

Ditaa convert ASCII diagrams into bitmap graphic (pictures)

Monday, May 12th, 2014

Reading Time: 2minutes

As part of my passion for ASCII art, I've found another interesting tool useful to ASCII art maniacs like me, the tool is called ditta and is able to convert manually drawn ASCII art diagrams to graphics, below is tool description from my debian apt-cache as well as a screenshot:

 apt-cache show ditaa|grep -i ditaa -A 4

Package: ditaa
Priority: optional
Section: graphics
Installed-Size: 164
Maintainer: David Paleino <>

Filename: pool/main/d/ditaa/ditaa_0.9+ds1-2_all.deb
Size: 107270
MD5sum: 05ec52d9274b954b053f1835ca5d7a7f
SHA1: 792d91d05fff2a2a19c0ebce317351d138436c18
SHA256: c4319d32e7918aab782e2f38cdad745bc9023f9f09a999033d983095ee4f70d5

 DiTAA is a small command-line utility that can convert diagrams drawn using
 ASCII art ("drawings" that contain characters that resemble lines, like | /
 and -), into proper bitmap graphics.
 DiTAA also uses special markup syntax to increase the possibilities of shapes
 and symbols that can be rendered.


To install ditaa on Debian and Ubuntu Linux:

debian:~# apt-get install --yes ditaa

Ditaa text diagram to Graphics converter is also available in Fedora Linux and in Source RPMs to be used on Redhat Based RPM distributions.
To install in most of RPM based Linuxes:

[root@fedora:~]# yum install -y ditaa

For most people probably Ditta will not be of any value except as a PoC and of a Hack value just like Ditaa's home page suggests. Nomatter that Ditta is cool but has just 2 drawback it doesn't understand non-latin characters i.e. Cyrillic and requires Java Virtual Machine .. but if you're a real geek you will do  the sacrifice to install a whole bunch of the heavy java for the sake of some oldschool fun 🙂 Being written in Java makes Ditta multi-platform, but you will need a Java VM version of at least 1.6 (it doesn't work with Java 1.5).

The format Ditta understands is close to HTML

<ditaa [optional parameters]>
... (some ditaa-code) ...

There are also special tags understood by Ditta which are automatically turned into shaped graphical buttons and forms.

Possible tags

Not all shape selector tags are documented on the ditaa site. A quick source scan revealed:

tag Description
{c} decision(Choice)
{d} document
{io} input/output, parallelogram
{mo} manual operation
{o} ellipse, circle
{s} storage
{tr} trapezoid (looks like an inverted {mo} )

Here is an example Ditta code

<ditaa round noedgesep right>
    +--------+   +-------+    +-------+
    |        | --+ ditaa +--> |       |
    |  Text  |   +-------+    |diagram|
    |Document|   |!magic!|    |       |
    |     {d}|   |  c478 |    |       |
    +---+----+   +-------+    +-------+
        :                         ^
        |       Lots of work      :

This Ditta code will generate following picture:

Create local network between virtual machines in Virtualbox VM – Add local LAN between Linux Virtual Machines

Wednesday, June 11th, 2014

Reading Time: 3minutes


I want to do test MySQL Cluster following MySQL Cluster Install Guide for that purpose, I've installed 2 version of CentOS 6.5 inside Virtualbox and I wanted to make the 2 Linux hosts reachable inside a local LAN network, I consulted some colleagues who adviced me to configure two Linux hosts to use Bridget Adapter Virtualbox networking (Network configuration in Virtualbox is done on a Virtual Machine basis from):

Devices -> Network Settings

(Attached to: Bridged Adapter)

Note!: that by default Cable Connected (tick) is not selected so when imposing changes on Network – tick should be set)
After Specifying Attached to be Bridged Adapter to make CentOS linux refresh network settings run in gnome-terminal:

[root@centos ~]# dhclient eth0

However CentOS failed to grab itself DHCP IP address.
Thus I tried to assign manually IP addresseswith ifconfig, hoping that at least this would work, e.g.:

on CentOS VM 1:

/sbin/ifconfig eth0 netmask

on CentOS VM 2:

/sbin/ifconfig eth1 netmask

To test whether there is connection between the 2 VM hosts tried ping-ing (from and tested with telnet if I can access remotely SSH (protocol), from CentOS VM2 1 to CentOS VM2 and vice versa, i.e.:

[root@centos ~]# telnet 22


telnet: connect to address No route to host

Then after checking other options and already knowing by using VBox NAT network option I had access to the internet, I tried to attach a standard local IP addresses to both Linux-es as Virtual interfaces (e.g eth0:1), .e.g:

On Linux VM 1:

/sbin/ifconfig eth0:0 netmask

On Linux VM 2:

/sbin/ifconfig eth1:0 netmask

Then to test again used telnet

[root@centos ~]# telnet 22

Then I found Virtualbox has a special Internal Networking support

to choose in Attached todrop down menu. According to Internal Networking Virtualbox instructions toput two Virtual Machine hosts inside an Internal network they should be both set in Internal network with identical name.
P. S. It is explicitly stated that using Internal Network will enable access between Guest Virtual Machines OS, but hosts will not have access to the Internet (which in my case doesn't really mattered as I needed the two Linux VMs just as a testbed)


I tried this option but it doesn't work for me for some reason, after some time of research online on how to create local LAN network between 2 Virtual Machines luckily I decided to test all available Virtualbox Networking choices and noticed Host-only adapter.

Selecting Host-only Adapter and using terminal to re-fetch IP address over dhcp:


On CentOS VM1

dhclient eht0

On CentOS VM2

dhclient eth1

assigned me two adjoining IPs – ( and

Connection between the 2 IPs and on TCP and UDP and ICMP protocol works, now all left is to install MySQL cluster on both nodes.
