The day of Victory over Nazism Russia and Belarus

Thursday, May 9th, 2013

Today 9th of May in Russia, Belarus, Ukraine and Kazakhstan still celebrate the day of Victory over Nazism in World War II. In relation to that in those country the day is official holiday. And everyone celebrates for great heroism of Soviet Soldiers who beat up Germany and Hitler's Nazism regime.
Unfortunately in Bulgaria and many of ex-countries part of Soviet Union does not celebrate it anymore. Today in Bulgaria we mark up the Artificial Holiday of Creation of European Union.

GPL Arcade Volleyball – DOS Volleyball oldschool game remake for GNU / Linux

Wednesday, December 21st, 2011

Do you remember that oldschool Arcade VolleyBall game which was so popular on 16 bit (8086 XT) computers.
I remember this game from the years I was 12 years old, back in the days where we the gamers distributed all the DOS games on 360 KB 5.25" diskettes

I was looking over the games available to install on my Debian GNU / Linux today just to be happily suprised to find GPL Arcade Volleyball an identical game remake of the old Arcade Volleyball 8086 classic freeware game.

I remember we spend many hours with friends playing on the old Manifactured in Bulgaria Pravetz 16! computers
During communism and post communism Pravetz was the only computer brand we could buy from the market, as there was limitations on the exported and imported tech equipment within the USSR union.
Pravetz computers are a literal remake of 16 bit IBM 8086 computers and the computer design and integrals was stolen from IBM 16 bit 8086 / 8088 PC architecture

Arcade Volleyball has set a mark on my generation and I believe many people will remember the times this game was a hit with a bit of Nostalgia 😉
In the Game GPL Arcade Volleyball Debian GNU / Linux

Besides being an identical remake of PC Arcade Volleyball , GPL Arcade Volleyball is even expanded as it includes extra features which the original game lacked. Game includes:

  • Network Volleyball client / server Game (up to 4 players)
  • 6 Game Themes which completely change the game look & feel to be modernistic

Here are few GAV screenshots of the different existing game Themes:

Screenshot GPL Arcade VolleyBall Yisus

Yisus GAV Theme gameplay screenshot

GPL Arcade Volleyball Unnamed Theme Screenshot

GPL Arcade Volleyball unnamed Gameplay Theme Debian
GAV – Unnamed Theme Gameplay

Screenshot GAV FABeach gameplay
GAV – FaBeach Theme Gameplay

GAV supports both Window and fullscreen modes. To enable Fullscreen mode, while inside the game use:

Extra -> Fullscreen (Yes)

Saving preferences is also something which I if I recall correctly the original game lacked. This is done by navigating to:

Extra -> Save Preferences

GAV is said to support Joystick in resemblance to the original DOS game, though I've never tested it with a joy.

One of the greatest GAV game (hacks) is the Inverted Theme. Selecting it inverts the order in the game, where the game player becomes the volleyball ball and the ball becomes the player 😉

GPL Arcade Volleyball Arcade Inverted Theme - remake of DOS Volleyball Arcade
GAV does not yet not have a Free / Open / Net BSD port as far as I currently see, anyways since the game is Free Software probably soon a port will be available for BSDs as well.
The default GAV game controls are a bit untraditional. By default the one player game starts you play Volleyball game player positioned on the left.

For left player the default control keys are:
 

  • z – move player left
  • c – move player right
  • left shift – jump

Right player controls are:
 

  • Left – left (arrow key)
  • right – right (arrow key)
  • jump – up cursor key

GAV supports also a shortcut key for switching between windowed and full screen game mode by pressing F10
Installing the game on Debian and Ubuntu Linuces is done with:

linux:~# apt-get --yes install gav

Unfortunately gav does not have a definition to be added to GNOME or KDE Applications menus, thus to start the game after installed one has to do it manually by typing either in gnome RUN (Alt+F2) or on command line:

linux:~$ gav

Happy playing 😉

The no-ego deadly body and soul (anti-christian) philosophy a trend in modern Business – think always positive be always positive

Modern day Business training Sect picture

These days it’s ultra modern in Business and Business Communities, that the way business is made or business possibilities are discussed are directly influenced by altered understanding of Buddhistic world views.

Today less and less people realize that the modern day Western and Eastern Christian countries are rapidly loosing their Christian mark.
It was Christianity and Christian philosophy, thanks to which Christian countries has advanced to the material goodness level, architectural greatness, science improvements and civilization achievements that we the Europeans and other Western societies like Americans enjoy today.

As time ticks on the world is constantly becoming more and more Anti-Christian. From the times when Christianity was officially wide-spread and accepted and being a Christian was a sign for personal qualities and goodness, it’s now considered to be almost a crime or being insane if you have faith in Jesus Christ as God’s Son and a Saviour of mankind.

Business ethics practices from the past, which were often based on Christian ethics has also seriously changed these days.

It was due to Christianity and the Christian civillization due to which we had a dozens of genuine musician like: J. S. Bach, Beethoven, Verdi, Brahms, Tschaikovsky etc. the list of great people and musicians goes innumerous here.

The Roman Catholic and Easter Orthodox Christians thanks to which works, science has advanced is also innumerous, just to name a few for instance:

Nicolaus Copernicus, Galileo Galilei, Max Planck, Marie Curie, Theodosius Dobzhansky, Isaac Newton, James Clerk Maxwell, Johannes Kepler

again this is just a small chunk of all the great Christian people who by their talents has revolutionized the world for good.

However nowdays education is changed seriously and as many people should have noticed Christianity and historic relation between science and Christianity is trying to be covered.
Moreover the historic importance of Christian faith and it’s surrounding philosophy is forgotten, not to mention that officially the history of the world until the 18 century is mostly, a history of Christianity and it’s influence on society.

In these days of Christian apostacy, many of the business people in their look up for ways to become superior and rule over the masses has turned into various long forgotten sects and heresies which were publicly announced by ancient Christian Church as body and soul destroying dangerous teachings.

It’s trendy today that the confucionism or hindu influenced beliefs about the world and the way stuff works, are preached and used in businesses and business organizations.
Dalai Lama Enemy of Christianity

It’s classics nowdays that people run a business, after building a group of people, over which hierarchical manipulation based leadership is exercised.

Most oftenly people who enter into a new business field, try build a groups of people who are introduced without having conscious idea to veiled alterated buddhistic philosophy to match certain people’s idea or beliefs about the world.

These groups usually consist of people ranging from hundereds to thousands. Usually each of these business groups created, has a leader who is both leader in terms of (being the group boss / executive) and also a spiritual leader.

Interaction between the group members are purely based on manipulation. People are teached they have some special sensitivity for the surrounding environment which they can develop.
They’re teached they must always be positive, the group leaders (teachers) does try to suggest to the group what the group members understanding of positive should be.

In those business groups, people are taught by the leaders to be positive, while the leaders themselves are not positive (one cannot be positive without God!). People are constantly told “be positive”, “be positive”, while the people who teach them this are not positive at all and evil often cruel!
In other words group members are being re-taught the basics of how they perceive themselves and how they should perceive the world around them in a light that fits well with the business organization they’re membering in.
Consequently people are taught to loose their ego.
Loose Ego surrealism picture

This is one of the most essential parts of this modern day business false teachings. In reality loosing the ego is loosing one’s standing ground and through that the person in the group becomes easily manipulated by other group members.

When people loose their ego basicly they loose their protection against being easily manipulated, they loose their idea about what is good and what is bad, what is right and what is wrong and who in reality they’re.

I believe also the no-ego philosophy has also a straight relation with the modern day society problem of NO IDENTITY issue , I have previously blogged about.

Being exposed to this “business” approaches in that poor state one start easily accepting suggestions from the group leaders or other group members and could end up in a state where he is totally manipulated (a spiritual slave of the group leader GURU).

After time passes and a person is involved in so many meetings, the group members gets so much bounded together that they have to constantly meet each other and discuss things, (often senseless things), nevertheless the pointlessness of the many discussions this meetings starts giving them the feeling of great importance or in other words reveals them the ultimate life meaning.

Consequently, when the new business group entity is tight enough, the group is instructed by the leaders about what kind of business moves will be best for each of the group individuals and the overall business the group belongs to.
At this state each of the members should obey wholeheartedly, if somebody tries to question the leadership decisions, the leader does incite the whole group members against the disobeying member and usually the members gets destroyed.

These business group building philophy is also influenced by antrophology and observence of animal behaviour’s let’s say coyottes or wolves.

In animal world usually each pack of wolves had their leader and the pack only attacks if the leader hits and if the whole group is together.
Same kind of thing comes to business built entities based on this loose your ego / no-ego philosophies.
modern business group building - a spiritual babylon

A lot of pseudo beliefs about para-psychology and experimental western psychology is also involved and preached to the group members.
Loosing the ego philosophy in Business is directly influenced by buddhistic idea about Nirvana and spilling the self in the ultimate worldly reality (e.g. becoming one with the whole nature).
This kind of belief is seriously anti-christian and against the spiritual goal in christianity which is not the emptiness like in buddhism and the other eastern religions, but the goal is fullness in God.

We the Christians are striving to fill ourselves with God’s Spirit – The Holy Spirit, whether buddhists are trying to empty themselves by everything that’s binding them to reality (obviously they also try to empty themselves by God who has initially created man as his vessel).

Also in business, I’ve noticed in my experience that it’s common people who are taught business in universities or are introduced to business are taught philosophies which are very typical for western buddhist teachings.
Just like in buddhism people are taught there is no absolute good or evil and there is no good and bad and everything one does is good, if he sees it as good (we’re the one who define our lifes and realities)!!

Think for a while and see for yourself how insane this kind of philosophy is, let’s say I kill a man who I hate, that’s fine according to this philo because I believe this man’s existence was not good in my view and his unexistence will make the world a better place, since I believe it’s that way then it’s that way DOT!!!As a Christian I must confess this is ULTIMATE INSANITY, AN ULTIMATE LIE obviously inspired by the evil which is an enemy to us the Christians as the Holy Bible teaches.

This kind of “no good and bad” philosophy is a hidden assault against our Christian roots society, faith and civillization. In Christianity we’re clearly taught there is ultimate good an ultimate evil and there is no in between!
We are also taught one can become part of the ultimate good or ultimate evil by his daily choice, e.g. (get closer to God and his Holy Angels or distance himself from God and come near the devil and his fallen angels).

Mixing spirituality and business concepts has become a sad reality of our age, I’ve seen many books being sold which were claiming to teach, “how to do business based on Zen Buddhism and other eastern religions and philosophies.

What’s even worse is that people who are involved into this kind of “innovative” taught business approaches guarantee themselves to get exposed to the ultimate evil spirituality (devilish spiritual influence), as they openly reject God’s dominion over one’s self and the world around them.

The good news is that they’re many Christian Business communities as I’ve checked online, there are many people yet who do their best to do business with other Christians or people who still keep the Christian faith and morale.

Why does Orthodox Christian priests and monks wears long beards and why Roman Catholics does not

Thursday, May 19th, 2011

A really Long bearded Orthodox Christian Priest

One might question why does Orthodox Christian priests wear beards? and why does the long beards of our Orthodox priests makes differences with the Roman Catholics?

Here are the few reasons:

1. Long beards wearing’s tradition among Orthodox Christian priests and monks comes after Christ

Christ himself had a beard as it was normal and considered proper for a man to wear long beard.

The fact that our Lord Jesus Christ had a long beard himself can clearly be observed on all our Orthodox Christian icons:
The Lord Jesus Christ Sinai monastery ancient icon Pantocrator from the 6th century

The Lord’s Pantecrator Icon (Pantocrator / Pantecrator ) from the 6th century

2. Long beards priest wearing comes as a natural tradition from the Old Testament’s times and the tradition of early Church

If one reads thoroughfully the old testament, he will find out that even from Moses and Aaron and onwards the tradition is the same.
All the Godly man and the priests had their long beards unshaved as a mark for their belongship and dedication to God.
To generalize the long beards wearing is according to ancient old testamential ancient tradition.
The long beards tradition as an ancient Jewish religion (Old testamental) tradition can still be clearly observed in Jewish rabbis (nowdays the jewish priests), who still wears their beards long, like for example you can see in the picture below:

Jewish Rabbi weiss picture
A modern day Jewish Rabbi notice the beard 🙂

The long beards tradition later was adopted by Muslims when Islam emerged as a religion and more specificly by the muslim priests the Hodjas:

Sait Muslim Hodja Picture

One very interesting historical source of information which proofs that the ancient Church’s priests had the tradition not to cut their beards is given by the historian Egezit who writes in his Chronicles that st. Apostle James, the head of the Church in Jerusalem, never cuts his hair.

A source of confirmation that the long hear and beards wearing was an established tradition that dates back to the old testament is found in the old testament in (Ezekiel 8:3)

Here is what exactly we read there:

He stretched out what looked like a hand and took me by the hair of my head.
The Spirit lifted me up between earth and heaven and in visions of God he took me to Jerusalem,
to the entrance to the north gate of the inner court, where the idol that provokes to jealousy stood.

3. Long hair and beards wearing by the Monks

An interesting fact is why does the Monks and novice neophyte lay brothers also stick to the ancient tradition.
It appears long hair and beards wearing traces back to the holy life of the ascetics of the deserts (e.g. the hermits).

The reason why ascetics did not shaved their hairs or bears as a way to avoid vanity and therefore this old hermitage practice has also had a spiritual reason.

4. The Nazarite old testament tradition

In the old testament in Numbers 6:1-21, we read about the term nazarite which means consecrated / separated

Each boy or man who was to become a Nazarine has been devoted to God for a certain period of time or in some cases for his all life, one of the many conditions for one to be a nazarite is not to shave his beard or hair.
One can read about this in the old testament in Leviticus 21:5

Leviticus 21:5
"They shall not make baldness upon their head,
neither shall they shave off the corner of their beard nor make any cuttings in their flesh."

There are some other prohibitions relating to Nazarite’s one of the most notable ones is found in Numbers 6:4:

All the days of his Naziriteship shall he eat nothing that is made of the grape-vine,
from the pressed grapes even to the grapestone.

One example for people who gaves vow to become temporary Nazarites is found in 1 Maccabees 3:49 (this book is only available in the Orthodox Holy Bible).
One of the most important figure in Christianity that used to be Nazarite is Samson, his life can be read in the old testament in Judges 13 – 16

As we read in Judges , Samson’s great God given power consituted in a prohibition to shave his hair and not to drink wine.

5. Reason why Roman Catholic Priests and monks abandoned the ancient tradition of wearing long hairs and beards

In the early Roman Empire it was a customfor a men to shave. The “enlightened” Romans believed that only the barbarians did not shaved themselves, and as you can imagine Jewish people and early Christians were of course considered to be barbarians, e.g. being unshaved was a sign for a cultural inferiorness in according to Romans comprehension.

The long hairs and beards tradition in the Western Church has started disappearing and consequentially completely lost with the Tyranny of Charlemagne at the end of the eight century.
With his massive ‘barbarian’ inferiority complex, it was his desire in all things to imitate pagan classical Rome.
It was therefore under him that Western clergy were ordered to shave regularly.
For example at the Council of Aachen (816), it was stipulated that priests and monks were to shave every two weeks.

By the beginning of the 11th century the tradition of wearing long beards was already completely torned apart and almost all the Roman Catholic clergy was regularly shaving.

In the sixteenth century beardlessness for Roman Catholic clergy was enforced by further canons,
which appear to have been dropped since the Second Vatican Council.

6. Why does protestants does not wear beards

As we all know protestant Church denominations has emerged as schismatics from Roman Catholic church and therefore mostly the influence they had was from Roman Catholics which already had the tradition within their clergy to regularly shave, thus pastors shaving was completely out of question and never come to an established reality among the Protestant Church pastors.

7. Is the Orthodox Christian layman obliged to wear beards

Absolutely not! The layman within the Orthodox Church can choose for themselves, if they want to wear their hair and beard and through that possess an image physically similar to Christ.
In my view it’s more righteous for us the layman to wear our hairs and beards as I personally believe long hair and beards demonstrates mans dignity and God’s dedication, but this is my own private opinion.
At many cases wearing beards or long hairs is an obstacle for a good integration in nowdays society, so if wearing a beard or hair as laymans does become an obstacle for our normal daily lifes then I believe cutting a long beard or hair is perfectly acceptable.
Moreover even the Orthodox Christian priests are not enforced to wear beards and in some cases where the priest’s wife is against the beardness the Orthodox priest is allowed to shave himself, though as a matter of fact having a completely shaved priests in our Orthodox Churches is rare and less common today.

In conclusion wearing of beard and long hair by Orthodox Christna clergy, has come from the desire to physically resemble Christ.
This physical resemblance is a symbol of the spiritual resemblance of Christ’s humility, which is the ultimate aim of our life.

During such attacks your /var/log/messages or /var/log/auth gets filled in with various failed password logs like for example:

This brute force dictionary attacks often succeed where there is a user with a weak a password, or some old forgotten test user account.
Just recently on one of the servers I administrate I have catched a malicious attacker originating from Romania, who was able to break with my system test account with the weak password tset .

Thanksfully the script kiddie was unable to get root access to my system, so what he did is he just started another ssh brute force scanner to crawl the net and look for some other vulnerable hosts.

As you read in my recent example being immune against SSH brute force attacks is a very essential security step, the administrator needs to take on a newly installed server.

The easiest way to get read of the brute force attacks without using some external brute force filtering software like fail2ban can be done by:

1. By using an iptables filtering rule to filter every IP which has failed in logging in more than 5 times

To use this brute force prevention method you need to use the following iptables rules:
linux-host:~# /sbin/iptables -I INPUT -p tcp --dport 22 -i eth0 -m state -state NEW -m recent -set
linux-host:~# /sbin/iptables -I INPUT -p tcp --dport 22 -i eth0 -m state -state NEW
-m recent -update -seconds 60 -hitcount 5 -j DROP

This iptables rules will filter out the SSH port to an every IP address with more than 5 invalid attempts to login to port 22

2. Getting rid of brute force attacks through use of hosts.deny blacklists

sshbl – The SSH blacklist, updated every few minutes, contains IP addresses of hosts which tried to bruteforce into any of currently 19 hosts (all running OpenBSD, FreeBSD or some Linux) using the SSH protocol. The hosts are located in Germany, the United States, United Kingdom, France, England, Ukraine, China, Australia, Czech Republic and setup to report and log those attempts to a central database. Very similar to all the spam blacklists out there.

To use sshbl you will have to set up in your root crontab the following line:

*/60 * * * * /usr/bin/wget -qO /etc/hosts.deny http://www.sshbl.org/lists/hosts.deny

To set it up from console issue:

linux-host:~# echo '*/60 * * * * /usr/bin/wget -qO /etc/hosts.deny http://www.sshbl.org/lists/hosts.deny' | crontab -u root -

These crontab will download and substitute your system default hosts with the one regularly updated on sshbl.org , thus next time a brute force attacker which has been a reported attacker will be filtered out as your Linux or Unix system finds out the IP matches an ip in /etc/hosts.deny

The /etc/hosts.deny filtering rules are written in a way that only publicly known brute forcer IPs will only be filtered for the SSH service, therefore other system services like Apache or a radio, tv streaming server will be still accessible for the brute forcer IP.

It’s a good practice actually to use both of the methods 😉

My Individual Strategic Human Resources Management (SHR) research paper for Arnhem Business School

Thursday, April 7th, 2011

The previous semester in Arnhem Business School, I’ve followed a module called Strategic Human Resources Management
as a part of the so called G-cluster (Grand Cluster) (the 3rd year second semester).

The Stragic HR subject (module) is a completely meaningless one and the best short way to describe it is with the word (an insanity!).
In reality there is no aim of this module, and it’s content is vague and irrelevant.

If you’re a student in Arnhem Business School (ABS) and you have as oligitory to follow this course you’re seriously in trouble.

The whole subject is a lot of bla, bla, the teachers attitude towards you is like they’re invincible and you’re a victim and you have to always obey the teacher or you’re out (fear based)

Anyways I would skip to describe how the Strategic HRM went through as it was a complete nightmare ..

As a part of the Strategic HRM course It was necessery to write the so called Strategic Paper, the paper was required as a proof to the teachers that the student has realized what Strategic HRM is.

I believe my paper became quite good and thus I decided to share it here on my blog in hope that some other students might benefit from my Strategic Human Resources and Management research paper.

Here is the strategic paper assignment document and the paper itself:

1. Assignment Strategic Paper for semester 2010-2011
2. Strategic Human Resources Research Paper in DOC format
3. Strategic Human Resources Research Paper in PDF format

As I passed the Strategic HRM and it was one of the weighting factors for the subject end mark, it appears my research paper was found to be a good one by the teachers and therefore I assume other students from HAN might like to read it as a sample if they have to write something similar.

Two successfully taken exams

Friday, May 16th, 2008

Blessed be God, for he heard my prayers. I asked to pass the German re-exam. And HalleluYah! 🙂 I did with 4.20. Also I have a mark of 3 on the other exam at Finance and Accounting II ! I was almost sure I would fail on that exam but still have prayed the night before the exam. Although I’ve most probably done from the Task given on the exam the same part as my collegues does I still got 3 ! HalleluYah! again two days passed from then but still the joy remains! :)END—–

The end of the work week :)

One more week passed without serious server problems. Yesterday after upgrade to debian 4.0rc2 with

apt-get dist-upgrade and reboot the pc-freak box became unbootable.

I wasn’t able to fix it until today because the machine’s box seemed not to read cds well.The problem was consisted of this that after the boot process of the linux kernel has started the machine the boot up was interrupted with a message saying
/sbin/init is missing

and I was dropped to a busybox without being able to read nothing from my filesystem.Thankfully nomen came to Dobrich for the weekend and today he bring me his cdrom-drive I booted with the debian.

Using Debian’s linux rescue I mounted the partition to check what’s wrong. I suspected something is terribly wrong with the lilo’s conf.

Looking closely to it I saw it’s the lilo conf file it was setupped to load a initrd for the older kernel. changing the line to thenew initrd in /etc/lilo.conf and rereading the lilo; /sbin/lilo -C; /sbin/lilo;

fixed the mess and pc-freak booted succesfully! 🙂

Yesterday I had to do something kinky. It was requested from a client to have access to a mysql service of one of the company servers,the problem was that the client didn’t have static IP so I didn’t have a good way to put into the current firewall.

Everytime the adsl they use got restarted a new absolutely random IP from all the BTC IP ranges was assigned.

The solution was to make a port redirect to a non-standard mysql port (XXXXX) which pointed to the standard 3306 service. I had to tell the firewall not to check the coming IPs on the non-standard port (XXXXX) against the 3306 service fwall rules.

Thanks to the help of a guy inirc.freenode.net #iptables jengelh I figured out the solution.

To complete the requested task it was needed to mark all packagescoming into port (XXXXX) using the iptables mangle option and to add a rule to ACCEPT all marked packages.

The rules looked like this

/sbin/iptables -t mangle -A PREROUTING -p tcp –dport XXXXX -j MARK –set-mark 123456/sbin/iptables -t nat -A PREROUTING -d EXTERNAL_IP -i eth0 -p tcp –dport XXXXX -j DNAT –to-destination EXTERNAL_IP:3306

/sbin/iptables -t filter -A INPUT -p tcp –dport 3306 -m mark –mark 123456 -j ACCEPT .

Something I wondered a bit was should /proc/sys/net/ipv4/ip_forward in order for the above redirect to be working, in case you’re wondering too well it doesn’t 🙂 The working week was a sort of quiteful no serious problems with servers and work no serious problems at school (although I see me and my collegues become more and more unserious) at studying. My grand parentsdecided to make me a gift and give me money to buy a laptop and I’m pretty happy for this 🙂 All that is left is to choose a good machine with hardware supported both by FreeBSD and Linux.
