Merry Christmas from Pomorie Monastery and a small monastic fire that ended well

Thursday, December 26th, 2013

chestito-rojdestvo-hristovo-merry-Christmas-a-monastery-fire-stopped-by-Gods-grace

I spend the Christmas eve for a first time in Monastery with the brotherhood in Pomorie monastery. The night on 24-th against 25-th when Christmas is celebrated in Bulgaria was marked by the usual morning service and a Holy Liturgy. Silent Night Holy Night song was sung in the Church near the end of the Holy Liturgy.

All went well except small fire incident, out of a suddenr right after the end of the Church service a fire ignited  in one of the monastery store rooms. Actually it was a huge miracle that the fire didn't spread in whole monastic cell buildings as the fire used to be active without anyone noticing it for about 6 hours or so. The restult of fire was that  just one room full of sheets and sanitary equipment burn out completely. The fire happened in a room nearby my room on second stage one stage lower (on first floor). The fire brigade come quickly and stashed the fireplace without serious troubles.

The fire would have quickly spread if in the burning room if only one of the water tubes didn't break up pouring water inside on the burning stuff. The fire emerged around 12:40 and was already еxtinguished for less than hour. Thanks God there was no one in the burning room and no victims  Another sure miracle is that today weather is very calm no wind blowing so fire didn't ignited in a quick pace and was easily extinguished.  

Below are the immersly beautiful Christmas Church Troparion, Kontaktion and Feast singings as translated to English

Thy nativity, O Christ our God,
has shown to the world the light of wisdom;
for by it, those who worshipped the stars
were taught by a star to adore Thee
the Sun of Righteousness,
and to know Thee, the Orient from on high.
O Lord, glory to Thee."

Today the virgin, gives birth to the incomprehensible One;
and the earth offers a cave to the unapproachable One;
Angels and shepherds glorify Him;
the Wisemen journey with a star;
since for our sakes is born the ETERNAL GOD, as a little Child.

Christ is born, glorify him.
Christ is from heaven, go to meet him.
Christ is an earth, be ye lifted up.
Sing to the Lord, all the earth.
Sing out with gladness, all ye people.
For he is glorified.

To the Son begotten of the Father
without change before the ages,
and in these last times without seed made flesh from a Virgin,
to Christ God let us cry aloud:
Thou hast exalted our horn. Holy are Thou, O Lord!'

Rod of the root of Jesse,  and flower that blossomed from his stem, O Christ,
Thou hast sprung from the Virgin.
From the Mountain overshadowed by the forest
Thou hast come, made flesh from her that knew not wedlock,
O God who art not formed from matter.
Glory to Thy power, O Lord.

As Thou art God of peace and Father of mercies,
Thou hast sent us Thy Angel of great counsel,
Who grants us peace;
so we are guided by the knowledge of God,
watching before dawn we glorify Thee, only Lover of mankind'.

The monster from the deep
spat Jonas from its bowels like a new born babe,
just as it had received him;
while the Word having dwelt in the Virgin and taken flesh,
came forth, yet kept her incorrupt,
for being himself not subject to decay,
he preserved his mother free from harm'.

The Youths brought up together in godliness,
scorning the impious decree,
feared not the threat of fire,
but standing in the midst of the flame they sang:
God of our Fathers, blessed are Thou!

The furnace moist with dew was the image and the figure of a wonder past nature;
for it did not burn those it had received;
even as the fire of the Godhead
did not consume the Virgin's womb into which it has descended.
Therefore in praise let us sing:
Let all creation bless the Lord,
and highly exalt Him to all the ages.

Magnify, O my soul, the most glorious Theotokos,
more honourable and more glorious than the hosts on high.
'I behold a strange and wonderful mystery,
heaven is the Cave, the Cherubim thrown — Virgin,
the Manger the Place in which Christ lay,
the God whom nothing can contain. Whom we praise and magnify.

I wish to my dear readers have a great and blessed Christmas Holiday time, let Christ's love, peace and mercies are abundant in your hearts!

Saint Elijah Monastery a Nun monastery in the heart of Sofia suburb Mladost 2 (Dyrvenica)

sveti Eliah monastery Church in mladost 2 suburb monastery near heart of Sofia

Sofia (Bulgaria) is a notable city for those looking for spirituality. There are several monasteries situated inside the city. I'm living in Sofia since only 3 months and still I didn't found the time nor had a car to ride in them. So far I was only in one of the monasteries nun Monastery saint Elijah (svet Iliq) 3 years ago when I was guest of  a dear friend one Sunday evening he bring me there. St. Elijah monastery is situated in Mladost 2 city suburb (at the end of Dyrvenica suburb).
Today I rided to the monastery with my girlfriend Svetlana for the Night evening service. We was there about 17:00 but unfortunately the evening service was just over in this monastery evening service begins in 16:00. The serving priest was still there and we had a small chat with them, just to find out he used to be the old Abbot of Shipchenski Monastery. I was earlier in Shipchenki Monastery and I know personally current Abbot there father Ianuarij and was curious to know the priest just met is the spiritual father of fr. Ianuarij (name meaning January). The monastery is very little and I could see only one of the nuns who was very hospitable with us. Before approaching the monastery there is a tiny pine tree forest.

St. Elijah Monastery started its existence during the old period when Bulgaria was under a turkish Slavery in year 1595 on a place where Turkish army slaughtered a number of Bulgarian Orthodox Christians refusing to accept Muslim faith.Slaughtered martyr Christians were thought to be part of the small revolt organized by Bulgarian revolutionaries trying to free Bulgarian land from the yoke of Turkish Empire. Short after on place of monastic Church a cross in remembrance of the martyrs was set. Since martyrdom of Bulgarian Christians the place was believed to be sacred and many people went there to pray to God to help them in the various troubles of their daily lives.

Later on a small chapel was built on place of martyrdom and other small buildings were build soon to become a fully functional monastery. Current Monastery Church and monk cells buildings were re-build next to the remains of the old monastery in y. 1924. In Sofia's st. Elijah monastery are kept many middle aged 15th century Church slavonic books, unique ancient icons present from Russia to Bulgaria at the end of Turkish-Russian Bulgarian liberation war.
Most valuable monastic sanctuary is a big tapestry – The Mother of God with the infant.
As of time of writting the Abbes is mother Matriona which by amazing Gods providence is also Russian.

Bulgaria Top outsource destination – 5th in the World and 2nd in Europe in list of best countries to outsource business to

why outsource in bulgaria bulgaria 5th in world and second in europe in outsourcing1

I was stunned today to find out my countryland Bulgaria is 2nd in Europe and 5th in the world in terms of most attractive outsourcing destination according to BTA (Bulgarian News Agency).
Bulgaria is ordering 5th after, India, Indonesia, Estonia and Singapore. The ranking of most attractive destination is based on factors;

  • General Competitiveness of Labor cost Worldwide
  • Eligibility of Workhand
  • Multilingual English speaking population (mainly young people)
  • Expertised highly educated people
  • Very Low Taxes (if compared to "developed" European countries)
  • Decreased transportation costs (produc transportation to Europe is generally cheap)
  • Internet bandwidth speed and high bandwidth connectiveness to worldwide Trade Markets

All this opens a big opportunity for economy development and inflush of fresh-money from outsourced jobs. Due to higher and European standard level of education in Bulgaria, the workhand pool in Bulgaria is usually more knowledgeable and better in quality if compared to rest of 3rd world countries India, Indonesia, Sinagopore etc. Bulgaria has generally good infrastructure and offers easy transportation of people and resources, something not so well developed yet in lets say India or Indonesia. Therefore opportunities for further development in Bulgaria as a leading outsource center in Europe are immerse in the coming 10 years. So far big companies who already realized the great Bulgaria potential like Comverse, HP, IBM etc. started actively hire people in Bulgaria and outsource their businesses but this mainly happens in Sofia.

bulgaria top business destionation for outsourcing 5th in world and 2nd in europe for outsourcing

The trend in long run however is that European leading companies start outsource in smaller cities and towns as well. Right now most prepared personal ready for outsourcing in Bulgaria is in field of Information Technologies, Electronics, Marketing, Transportation Equipment, Business Management, Chemical Industry, Food & Bevarage and Logistics. General outsourcing trend is more and more people working in not high qualitified labor to enter the market of out-sourcing. There are plenty of companies already in Bulgaria involved in textile (clothes) industry offering their cheap and high quality workhand to large external multinational companies like Zara, H & M , Versace etc.

Currently Bulgaria is considered the poorest countries in the European Union with the shocking minimal wage of 310 leva about (155 EUR) and avarage monthly sallary of 812 leva (406 EUR) monthly. The cheapness of Bulgaria is still unidentified gold field ignored by many Western Multinational companies. Outsourcing in Bulgaria has great advantages for European Countries based companies in terms of product logistics as product transportation cost and taxation within the European Union are very cheap if compared to rest of top non-EU outsourcing countries. Due to оbviously advantegous conditions in Bulgaria there are plenty of companies in Bulgaria already specialised in auditing outsourcing business risks and planning steps a company could partake to outsource its business in BG. Current Bulgarian government is making further attempts to relieve country's conditions to attract new business investors by 'Simplifying country's business registration and operations administration requirements and fostering better business environment' as said recently by second minister of economics Krasin Dimitrov in recent business forum "Opportunities and Challanges in Business Process Outsourcing (BPO) and Shared Service Centers (SSC) in Bulgaria"

Torus Trooper linux tunnel 3d fast pace speed up game screenshot

Whether you're looking for a game to kill some time and enjoy the old "spaceship shoot and run games" check out Torus Trooper.
Originally game was developed for MS Windows and is remake of an old Atari Arcade Game Tempest.

Those who played Tempest know well that this game was revolution for its time and probably remember also a similar world famous Space Duel game.

Arcade atari old scool tunnel game tempest one of atari pre 3d game classics

Atari's Tempest Arcade game

The objective of Torus Trooper is mega simple as in most arcade games. You're speeding up through a tunnel all time with a spaceship with the only goal to kill as many enemies  as you can and survive as longer as possible. Playing the game you can get some memories of demoscene tracked music, future crew Second Reality / Unreal demos. Game was created by ABA GAMES company, authors Tumiki Fighters and GunRoar another 2 nice 2D Linux arcade games.

TUMIKI Fighters the boss level 1, 2d linux arcade game classic

Tumiki Fighters

Gunroar another cool linux arcade 2d game

GunRoar

Probably best thing of Torus Trooper is its nice graphics and superb demoscene like soundtrack.
I truely love the pace of the game, raising up the player adrenaline in minutes.
To install in a bundle Torus-Trooper Tumiki Fighters and Gunroar on Debian / Ubuntu Linux run the usual:

debian:~# apt-get install --yes torus-trooper tumiki-fighters gunroar
...

There is also a variation of torus-trooper called Torus Trooper, install and give it a try as well;

debian:~# apt-get install -yes torus-trooper-pure
...

In my humble opinion Torus-trooper is among golden games every Linux gamer should have installed on his Desktop.
Enjoy 🙂
 

Httpwatch a must have web developer and web hosting sysadmin Firefox / Internet Explorer / IPad / IPhone add-on

Monday, December 16th, 2013


Today a colleague of mine referred me to a wonderful Mozilla Firefox (Windows / Mac) plugin called HttpWatch.

HttpWatch is an HTTP sniffer for IE, Firefox, iPhone & iPad
that provides new insights into how your website loads and performs.
The plugin is quite simple it shows you all requests from your Browser to remote server with plenty of Debug information (on the fly). You can see exactly the Commands sent over the HTTP protocol as well as returned request status responce from Web Server (i.e. 200, 300, 400). By knowing the status returned by webserver you can debug odd problems with website authentication as well as oddities caused by proxies you don't know about. Besides showing responce returned on web requests HttpWatch shows also hand-shake of session ID variables. This makes the plugin  precious for Web developers and System Administrators working in Web & Middleware (Linux / Windows based Web Hosting companies)  etc.

HttpWatch is also a must have plugin for anyone looking to optimize a website for speed or for fixingwebsite responce time bottleneck issues. The size of plugin is quite big as of time of writting about 18.2 Megabytes. HttpWatch comes with separate app installer like any other stand alone Windows application.  Unfortunately Httpwatch does not have a version for GNU / Linux. Linux users could use HTTPFox, Google Chrome Developer tools or
Firebug.

Once you have plugin installed to check what's happening with a website access in (Firefox) select Tools -> HttpWatch. You will get a bottom screen new window with deug info.

httpwatch debugging accessed website information - web browser tool to optimize your website

Here is list of some of the many things for which plugin is useful;

  • Records HTTP
  • Decrypts HTTPS Traffic
  • Integrates with Internet Explorer & Firefox
  • Supports the SPDY Protocol in Firefox
  • Standalone Log File Viewer
  • Summary of Recorded Traffic
  • Grouping of Requests by Page
  • Collect Log Files From Your Customers
  • Request Level Time Charts
  • Real-Time Page Level Time Charts
  • Page Events
  • Detects Potential Problems
  • Customizable Data Columns
  • Data Tips
  • Automation Support
  • Advanced Filtering
  • Millisecond Level Timing
  • HTTP Compression
  • Network Level Performance Data
  • Extended Cookie Information
  • Shows Interaction with Browser Cache
  • Raw HTTP Streams
  • Export Data to CSV, HAR and XML
  • Import HAR files
  • Customizable CSV Export
  • Keyboard Accelerators
  • Access to Cached and Downloaded Content
  • Accurately Records Requests and Responses
  • Automatic Recording and Saving

Finally HttpWatch is a plugin to have next to Yahoo's YSlow, FasterfoxFireBug and Firefox's Web Developer plugin

How to fix problem with Skype No Video on MacBook Air with Mac OS X 10.8.6 / Mac OS X Repair OS file permissions with Disk Utility

Monday, December 9th, 2013

mac os x utilities disk utility reset Mac OSX file permissions to default
My girlfriend Svetlana has MacBook Air and just recently her skype Video calls stopped working once again after Mac OS X offered her to apply some update. Her notebook as of time of writting this post is running Mac OS X version 10.8.6. About 1 month and a halfago she was facing same Skype No VIdeo on Mac BookAri issues for how I fixed her No Video Skype issues back then check here. Initially I thought again the problem will be identical and to test if Web Camera hardware is detected on a hardware level by OS, I tried to check if it is displaying videoi FaceTime application. Last time there was no Video in Skype on her Mac Book Air  I remember clearly camera was detected on OS level and displaying well in Facetime, however this time even in facetime I couldn't see a capture of myself … As obviously problem was not in Skype Mac OS previous time fix of substituting AppleCamera.plugin with older version would not fix it. After some evaluation on problem and reading large number of posts on Apple support forums, I've came to the conclusion that it is possible the whole issues are faced by improper permissions applied by latest applied Mac OS update. In such cases people were recommending to Repair Mac OS Standard OS Files Permissions using an OS embedded tool called Disk Utility.
Disk Utility is an application that's built into OS X that can perform lots of useful and even scary actions.Sysadmins and advanced users seem to find frequent need of this handy tool but those newer to the Mac OS it is better to only use it after reading the docs and well realizing what exactly doing.

To Find / Open Disk Utility on Mac OS;

Launch Applications folder -> Utilities (folder), click the name of your startup disk, and select Repair Disk Permissions.

Mac OS X 10.8.6 Disk Utility Repair Disk Permissions screenshot
As I can understand from other ports reverting Mac OS File permissions to their default can solve a number of strange issues with Mac OS.
After repairing Mac OS X basis OS file permissions and testing in FaceTime and Skype, Camera god detected and Video was working fine 🙂
Hope this little article helps someone to fix same issues, if so please drop a thank you comment 😉

Adding Listing and Deleting SSL Certificates in keystore Tomcat Application server / What is keystore

Thursday, December 5th, 2013

Apache Tomcat keystore delete import list logo

 I work on ongoing project where Tomtat Application servers configured to run Clustered located behind Apache with mod_proxy configured to use ReverseProxy are used. One of customers which required a java application deployment experienced issues with application's capability to connect to SAP database.

After some investigation I figured out, the application is unable to connect to the SAP db server becuse remote host webserver running some SAP related stuff was not connecting due to expired certificate in Tomcat Keystore known also as JKS / Java Keystore– (.keystore) – which is a file containing multiple remote hosts imported certificates.

The best and shortest definition of keystore is:

Keystore entry = private + public key pair = identified by an alias

The keystore protects each private key with its individual password, and also protects the integrity of the entire keystore with a (possibly different) password.

Managing Java imported certificates later used by Tomcat is done with a command line tool part of JDK (Java Development Kit) called keystore. Keystore is usually located under /opt/java/jdk/bin/keytool. My Java VM is installed in /opt/ anyways usual location of keytool is $JAVA_HOME/bin/

Keytool has capabilities to create / modify / delete or import new SSL certificates and then Java applications can access remote applications which requires Secure Socket Layer handshake . Each certificate kept in .keystore file (usually located somewhere under Tomcat web app server directory tree), lets say – /opt/tomcat/current/conf/.keystore

1. List current existing imported SSL certificates into Java's Virtual Machine

tomcat-server:~# /opt/java/jdk/bin/keytool -list -keystore /opt/tomcat/current/conf/.keystore
password:
Command returns output similar to;

Entry type: trustedCertEntry

]

Note that password that will be promtped has is by default changeit (in case if you don't have explicitly changed it from Tomcat's default config server.xml).

2. Delete Old expired SSL host Certificate from Java Keystore
It is good practice to always make backup of old .keystore before modifying, so I ran:

tomcat-server:~# cp -rpf /opt/tomcat/current/conf/.keystore /opt/tomcat/current/conf/.keystore-05-12-2013

In my case first I had to delete old expired SSL certificate with:

tomcat-server:~# /opt/java/jdk/bin/keytool -delete -alias "your-hostname" -v -keystore /opt/tomcat/current/conf/.keystore

Then to check certificate is no longer existent in keystore chain;
tomcat-server:~# /opt/java/jdk/bin/keytool -list -keystore /opt/tomcat/current/conf/.keystore

-keystore – option is obligitory it does specify where keystore file is located
-list – does list the certificate
-v – stands for verbose

 

3. Finally to import new SSL from already expored via a browser url in keystore

tomcat-server:~# /opt/java/jdk/bin/keytool -importcert -file /tmp/your-hostname.cer -alias your-hostname.com -keystore /opt/tomcat/current/conf/.keystore

More complete information on how to deal with keystore is available from Apache Tomcat's SSL Howto – a must read documentation for anyone managing Tomcat.

Total Commander or Free Commander a must have Windows file Explorer alternatives

Total Commander must have windows file explorer alternative logo

Whether coming from Linux background and you're forced to work with MS Windows or even if you're born as a Windows user  and you hold a strong dislike for Windows File Explorer. You will certainly appreacite some Windows Explorer alternative like Total Commander.
 

1. Total Commander –  Windows Advanced File Manager

Total Commander was widely spread and still is mostly used by advanced Windows users since the distant 1996 when it came to exist.
Total Commander is highly spread among programmers and computer professionals. It is well known in Russia and the ex-Soviet Union block countries Total Commander is strongly preferred over Windows Explorer by anyone who ever had to work in Old command line MS-DOS, Unix consoles / Midnight Commander etc. Total Commander has just one downside it is not free as in freedom but shareware, so you either have to find a crack for it or everytime you run it press a number before you can proceed with it, this however is not such a big issue as usually you work with computer whole day and even if you should press a number once to continue run as Shareware, you have to do it just once or twice a day.

Total Commander windows internet explorer hackers alternative not registered screenshot

So why use Total Commander or Free Commander preferred choice over Windows Explorer and why it is better for one to use it:

1. Security

Big part of viruses have hidden attribute. Of course we can’t see it’s presence in Windows Explorer, this is so common with USB Drive Viruses. While MS Explorer has limited capability in showing system file, Total Commander is different, once it is specified to show hidden files, all kind of hidden files are to be shown.

2. Support for multiple upload protocols like FTP and SFTP

Through Total Commander plugins you can enjoy simplified way to do every operation from one interface. Once plugin for SFTP / Webdav … plugins you will not have to install separate clients like WinSCP / CarotWebDav etc.

4. Better file copying internal program

Total Commander's copier is much better than Windows Explorer default one. Lets say you have a power outage during copying a large file. What Windows Explorer will offer is overwrite the file loosing you time, whether Total Commander will continue copying from file byte size it stopped due to outage. Another advantage is it will be able to copy damaged files much better than Windows default copier program. TT's internal copy is not so quick as TerraCopy but faster than Windows Explorer default one..

5. More powerful search than Explorer's

TT has capabilities to search inside archives, set search encoding type. Search only by directories or files, set a range of dates from which files has to be found, search only hidden directories, search by directory file attribute, file size, look for duplicate files etc. etc.
