Preserve Session IDs of Tomcat cluster behind Apache reverse proxy / Sticky sessions with mod_proxy and Tomcat

Wednesday, February 26th, 2014

apache_and_tomcat_merged_logo_prevent_sticky_sessions
Having a combination of Apache webservice Reverse Proxy to redirect invisibly traffic to a number of Tomcat server positioned in a DMZ is a classic task in big companies Corporate world.
Hence if you work for company like IBM or HP sooner or later you will need to configure Apache Webserver cluster with few running Jakarta Tomcat Application servers behind. Scenario with necessity to access a java based application via Tomcat which requires logging (authentication) relaying on establishing and keeping a session ID is probably one of the most common ones and if you do it for first time you will probably end up with Session ID issues.  Session ID issues are hard to capture at first as on first glimpse application will seem to be working but users will have to re-login all the time even though the programmers might have coded for a session to expiry in 30 minutes or so.

… I mean not having configured Session ID prevention to Tomcats will cause random authentication session expiries and users using the Tomcat app will be unable to normally access below application with authenticated credentials. The solution to these is known under term "Sticky sessions"
To configure Sticky sessions you need to already have configured Apache/s with following minimum configuration:

  • enabled mod_proxy, proxy_balancer_module, proxy_http_module and or mod_proxy_ajp (in Apache config)

  LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule proxy_http_module modules/mod_proxy_http.so

  • And configured and tested Tomcats running an Application reachable via AJP protocol

Below example assumes there is Reverse Proxy Load Balancer Apache which has to forward all traffic to 2 tomcats. The config can easily be extended for as many as necessary by adding more BalancerMembers.

In Apache webserver (apache2.conf / httpd.conf) you need to have JSESSIONID configured. These JSESSIONID is going to be appended to each client request from Reverse Proxy to each of Tomcat servers with value opened once on authentication to first Tomcat node to each of the other ones.

<Proxy balancer://mycluster>
BalancerMember ajp://10.16.166.53:11010/ route=delivery1
BalancerMember ajp://10.16.166.66:11010/ route=delivery2
</Proxy>

ProxyRequests Off
ProxyPass / balancer://mycluster/ stickysession=JSESSIONID
ProxyPassReverse / balancer://mycluster/

The two variables route=delivery1 and route=delivery2 are routed to hosts identificators that also has to be present in Tomcat server configurations
In Tomcat App server First Node (server.xml)

<Engine name="Catalina" defaultHost="localhost" jvmRoute="delivery1">
In Tomcat App server Second Node (server.xml)

<Engine name="Catalina" defaultHost="localhost" jvmRoute="delivery2">

Once Sticky Sessions are configured it is useful to be able to track they work fine this is possible through logging each of established JESSSIONIDs, to do so add in httpd.conf

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"\"%{JSESSIONID}C\"" combined

After modifications restart Apache and Tomcat to load new configs. In Apache access.log the proof should be the proof that sessions are preserved via JSESSIONID, there should be logs like:
 

127.0.0.1 - - [18/Sep/2013:10:02:02 +0800] "POST /examples/servlets/servlet/RequestParamExample HTTP/1.1" 200 662 "http://localhost/examples/servlets/servlet/RequestParamExample" "Mozilla/5.0 (X11; Linux x86_64; rv:17.0) Gecko/20130807 Firefox/17.0""B80557A1D9B48EC1D73CF8C7482B7D46.server2"

127.0.0.1 - - [18/Sep/2013:10:02:06 +0800] "GET /examples/servlets/servlet/RequestInfoExample HTTP/1.1" 200 693 "http://localhost/examples/servlets/" "Mozilla/5.0 (X11; Linux x86_64; rv:17.0) Gecko/20130807 Firefox/17.0""B80557A1D9B48EC1D73CF8C7482B7D46.server2"

That should solve problems with mysterious session expiries 🙂

Web Application Load Balancer types and when to use what kind of Load Balancer

Monday, February 3rd, 2014

General load balancer types description / active / passive / static / dynamic and additional
In this small article I will try to clear it up the general types of Web Server Load Balancers available. Whether one choose a Load Balancer he has the option to use a software LB or a hardware LB one there are plenty of software load balancer scripts out there. In this pos t I will mention just what choice is available in hardware load balancer interface BigIP LTM F5 standard. Generally BigIP LTM Load Balancers can be grouped in Static, Dynamic and Additional. One or more Load Balancers can be configured in front of group or farm of appplication servers. When more than one load balancer is used in front of application Load Balancer could be Active Load Balancer and Passive Load Balancer.
Below information will hopefully be useful to Web and Middleware working sys admins and anybody involved in frequent and large web systems integration.

Static Load Balancing

LB_RoundRobin_ type of load balancing example picture


Round Robin Load Balancing

This is the default load balancing method. Round Robin mode passes each new connection request to the next server in line, eventually distributing connections evenly across the array of machines being load balanced.
Round Robin mode works well in most configurations, especially if the equipment that you are load balancing is roughly equal in processing speed and memory.

ratio_member_load_balancer picture diagram

Ratio (member) / Ratio (node) Load Balancer

   
The Ratio (member) system distributes connections among pool members or nodes in a static rotation according to ratio weights that you define. In this case, the number of connections that each system receives over time is proportionate to the ratio weight you defined for each pool member or node. You set a ratio weight when you create each pool member or node.

These are static load balancing methods, basing distribution on user-specified ratio weights that are proportional to the capacity of the servers.

dynamic_ratio_member_load_balancer picture diagram

Dynamic Load Balancers

 

Dynamic Ratio (member) Dynamic Ratio (node) LB

The Dynamic Ratio load balancing select a server based on various aspects of real-time server performance analysis. These methods are similar to the Ratio methods, except that with Dynamic Ratio methods, the ratio weights are system-generated, and the values of the ratio weights are not static. These methods are based on continuous monitoring of the servers, and the ratio weights are therefore continually changing.
   
The Dynamic Ratio LBs are used specifically for load balancing traffic to RealNetworks® RealSystem® Server platforms, Windows® platforms equipped with Windows Management Instrumentation (WMI), or any server equipped with an SNMP agent such as the UC Davis SNMP agent or Windows 2000 Server SNMP agent.

dynamic_load_balancing load balancer diagram picture with circles

Fastest (node) /Fastest (application) LB

   
The Fastest methods select a server based on the least number of current sessions. The following rules apply to the Fastest load balancing methods:

These LB require that you assign both a Layer 7 and a TCP type of profile to the virtual server interface where LB IP is binded.
If a Layer 7 profile is not configured, the virtual server falls back to Least Connections load balancing mode.

Note: If the OneConnect feature is enabled, the Least Connections methods do not include idle connections in the calculations when selecting a pool member or node. The Least Connections balancing use only active connections in their calculations.
   
Fastest node load balancing is useful in environments where nodes are distributed across separate logical networks.

 

Least Connections (member) / Least Connections (node) LB    

The Least Connections method are relatively simple in that the system passes a new connection to the pool member or node that has the least number of active connections.

Note: If the OneConnect feature is enabled, the Least Connections methods do not include idle connections in the calculations when selecting a pool member or node. The Least Connections methods use only active connections in their calculations.
   
The Least Connections balancing function best in environments where the servers have similar capabilities. Otherwise, some amount of latency can occur.

For example, consider the case where a pool has two servers of differing capacities, A and B. Server A has 95 active connections with a connection limit of 100, while server B has 96 active connections with a much larger connection limit of 500. In this case, the Least Connections method selects server A, the server with the lowest number of active connections, even though the server is close to reaching capacity.

If you have servers with varying capacities, consider using the Weighted Least Connections load balancing instead.

 

Weighted Least Connections (member) / Weighted Least Connections (node)

Like  Least Connections, these load balancing methods select pool members or nodes based on the number of active connections. However, the Weighted Least Connections methods also base their selections on server capacity.

The Weighted Least Connections (member) method specifies that the system uses the value you specify in Connection Limit to establish a proportional algorithm for each pool member. The system bases the load balancing decision on that proportion and the number of current connections to that pool member. Example is member_a has 40 connections and its connection limit is 200, so it is at 20% of capacity. Similarly, member_b has 40 connections and its connection limit is 400, so it is at 10% of capacity. In this case, the system select selects member_b. This algorithm requires all pool members to have a non-zero connection limit specified.

The Weighted Least Connections (node) method specifies that the system uses the value you specify in the node's Connection Limit setting and the number of current connections to a node to establish a proportional algorithm. This algorithm requires all nodes used by pool members to have a non-zero connection limit specified.

If all servers have equal capacity, these load balancing  behave in the same way as the Least Connections methods.

Note: If the OneConnect feature is enabled, the Weighted Least Connections methods do not include idle connections in the calculations when selecting a pool member or node. The Weighted Least Connections  use only active connections in their calculations.
   

Weighted Least Connections methods work best in environments where the servers have differing capacities.
For example, if two servers have the same number of active connections but one server has more capacity than the other, the BIG-IP system calculates the percentage of capacity being used on each server and uses that percentage in its calculations.

 

Observed (member) / Observed (node)

With the Observed methods, nodes are ranked based on the number of connections. The Observed methods track the number of Layer 4 connections to each node over time and creates a ratio for load balancing.
   

The need for the Observered methods is rare, and they are not recommended for large pools.

Predictive (member) / Predictive (node)

The Predictive methods use the ranking methods used by the Observed methods, where servers are rated according to the number of current connections. However, with the Predictive methods, the BIG-IP system analyzes the trend of the ranking over time, determining whether a nodes performance is currently improving or declining. The servers with performance rankings that are currently improving, rather than declining, receive a higher proportion of the connections.
   

The need for the Predictive methods is rare, and they are not recommend for large pools.

Least Sessions LB type

The Least Sessions method selects the server that currently has the least number of entries in the persistence table. Use of this load balancing method requires that the virtual server reference a type of profile that tracks persistence connections, such as the Source Address Affinity or Universal profile type.

Note: The Least Sessions methods are incompatible with cookie persistence.
   
The Least Sessions method works best in environments where the servers or other equipment that you are load balancing have similar capabilities.

 

L3 Address

L3 Address is same LB type as Least Connections methods.

How to count how many files are in a directory with find on Linux

Tuesday, February 21st, 2012

how to count how many directories are on your linux server

Did you ever needed to count, how many files in a directory are there?
Having the concrete number of files in a directory is not a seldom task but still very useful especially for scripts or simply for the sake of learning

The quickest and maybe the easiest way to count all files in a directory in Linux is with a combination of find and wc commands:

Here is how;

linux:~# cd ascii
linux:~/ascii# find . -type f -iname '*' -print |wc -l
407

This will find and list all matched files in any directory and subdirectories, print them out and count them with wc command.
The -type f argument instructs find to look only for files.

Other helpful variance of finding and listing all files in a directory and subdirectories is to list and count all the files with a certain file extension under a directory. For example, lets list all text files (.txt) contained in a directory and all level sub-directories:

linux:~/ascii# find . -type f -iname '*.txt' -print |wc -l
401

If you need to check the number of files in a directory for multiple directories on a server and you're aiming at doing it efficienly, issung above find .. | wc code will definitely be not a good choice. If used it will generate heavy load for the system and along with that will complete the execution in ages if issued on a large number of files containing dirs.

Thanksfully if efficiency is targetted, there is a command written in C called tree which is more efficient than find.
To count the number of files in dir but using tree :

linux:~# cd ascii
linux:/ascii# tree | tail -n 1
32 directories, 407 files

By default tree prints info for both the number of found files and directories.
To print out only the files matched, awk comes handy, e.g.:

linux:/ascii# tree |tail -n 1| awk '{ print $3 }'407

To list only the number of files in a directory without its existing sub-directories ls + wc use is also possible:

linux:~/ascii# ls -l | grep ^- | wc -l68

This result the above command would produce is +1 more than the real number of files, as it counts the directory ".." as one file (in UNIX / LINUX everything is file).

A short one liner script that can calculate all files correctly by substracting 1 is and hence present correct result on number of files is like so:

linux:~/ascii# var=$(ls -l | grep ^- | wc -l); var=$(($var - 1)); echo $var

ls can be used to calculate the number of 1-st level sub-directories under certain directory for instance:

linux:~/ascii# ls -l |grep ^d|wc -l
25

You see the ascii directory has 25 subdirectories in its 1st level.

To check symlinks under a directory with ls the command would be:

linux:~/ascii# ls -l | grep ^l | wc -l
0

Note above 3 ls | grep … examples, will not work properly if the directory contains files with SUID or some special properties set.
Hence to get the same 3 results for active files, directories and symbolic links, a one liner similar to the one below can be used instead:

linux:~/ascii# for t in files links directories; do echo `find . -type ${t:0:1} | wc -l` $t; done 2> /dev/null
407 files
0 links
33 directories

This will show statistics about all files, links and directories for all directory sub-levels.
Just in case if there is need to only count files, links and directories without directory recursion enabled, use:

linux:~/ascii# for t in files links directories; do echo `find . -maxdepth 1 -type ${t:0:1} | wc -l` $t; done 2> /dev/null
68 files
0 links
26 directories

Anyways the above bash loop will be slow, for directories containing thousands of files. For better performance the equivallent of above bash loop rewritten in perl would be:

linux:~/ascii# ls -l |perl -e 'while(<>){$h{substr($_,0,1)}+=1;} END {foreach(keys %h) {print "$_ $h{$_}\n";}}'
- 68
d 25
t 1
linux:~/ascii#
 In any case the most preferrable and efficient way to count files en directories is by using tree command.
In my view using always tree command instead of code "hacks" is smart idea.

In Slackware tree command is part of the base install, on Debian and CentOS Linux, tree cmd is not part of the base system and requires install via apt / yum e.g.:

debian:~# apt-get --yes install tree
...

[root@centos:~ ]# yum --yes install tree

Happy counting 😉

Flight to Dubai via Istanbul, my Dubai first impressions and how it feels to be in Arab country

Tuesday, September 13th, 2011

Burj Al Arab and the 360 degree club

On Sunday I had a flight to Dubai – the the United Arab Emirates. The flight's goal is to do some business meetings with potential investors willing to invest in Cadia Holding 's Ofsshore Solutions
I'm employed as IT & Security Specialist and business consultant as well as doing the system administration for the company

The company has already scheduled a business meetings to look for new investors in order to finance the current company offered products and services as well as finance its entrance in the field of biometrics technology for the people to allow people to pay in stores with no need for plastic cards only using a finger partial imprint and a code.

The flight from Sofia to Istanbul was about 1 h and 15 minutes and it went quite smoothly thanks God. It seems Sofia's Airport has changed a lot since my last flight before more than a year and half to Dotmund Germany.
Now Sofia's airport looks way more modern than before, which means Bulgaria is slowly but surely developing it's infrastructure 😉
Sofia Airport long distance view

I used an electronic ticket for the flight which was pre-purchased by Cadia so what, all I had to do on the airport is show a copy of my e-ticket and immediately, they hand me in the fly ticket necessery to check in for the airplane

I should say the flight with Turksih airlines was really enjoyable and the plane we flight with felt much more secure compared to the WizzAir's airus.

It is true the last time I flight with with Wizzair's Airbus it was in January and the weather was quite bad as there was harsh winter with a lot of snow and this might be the reason, why my flight with them felt so shaky.

Anyways before entering the plane I had to go throught the regular security procedures, where I had to remove all kind of metals in bas, pockets etc. and go through a metal scanner, they sa an (anti terourisim) measure, besides that one of the airport security personnel checked me thoroughfully if I dont' bring any kind of objects hidden in m clothes. Generally during the check up with the metal scanner and the check up person I was treated like a criminal …
The Turkish airlines, stewardesses and the service was wonderful and we were given a not too bi but decent lunch (my first time I eat in airplane ;)).

Turkish Airlines Istanbul Airport

The flight as went smoothly and we were in Istanbul about 12:00 at midday, after coming down from the bus we were transferred with a bus from the plane like 1 or 1.5 km to Terminal 2 (the terminal of arrival scheduled).
I travelled with another colleague Krasimir, so we had to check our Tickets in the ticket office and let them issue us the flight ticket based on the e-ticket.
After a quick check of our International travelling passport, so called red passpower we were let to enter the duty free zone full of stores for food, beverages, clothes, parfumes suits cafeterias and everything, tech equipment stores, book stores, turkish ice-cream, duner kebaps and mostly any kind of shops and tings one can think of.

AtaTurk airport Istanbul picture
Ataturk Airport Istanbul

Something that catched my attention was that actually the model of how things are ordered and what they sell, the elevators the materials for building in the airport was very much like how things are in westerm country.
I thought it's a bit sad that everybody, everyone is following a modern design and a specific kind of order of things literally followed after the way things are in the western world. This somehow kills partially the uniqueiness of the country's culture and gives it a taste of the west, where the original culture and traditions the country possess somehow stay in the background.

What made me a bad impression on the airport is the too high prices of food and drinks. I just took one coffee (cappucino) and it costed me the solid sum 5 EUR!!
I was even fooled by the Turkish guy as if converted the coffee price from Turkish currency (Liras), when I calculated the price of the coffee was actually about 4 euro.

I've also spotted that in Turkey they're big nationalists. I've been told by Krasi the airport of Istanbul is called Ataturk and it appears this is the biggest airport in all Turkey. I've noticed in the bookstores we went through many many books even in English talking about the greatness of Turkey's first president Ataturk. There is no doubt that Ataturk has done a lot for internationalizing Turkey, it seems in Turkey they consider Ataturk as a national hero, but in my view it is a bit too much, somehow it looked like Ataturk's great respect in Turkey is comparable to the Chineese's love for Mao Dun ….

We had to spend some 4 hours with Krasi before the time for the second fly comes, so we had 4 hours to take a general look over everything offered in stores on the airport to kill some time

I was quite amazed to see so big variety products and goods on the same place, there was basicly everything one needs except furniture offered ont he airport.
The bookstores English books was reallya lot, where I should say it was quite good that about 40% of the books to be sold, were in English (quite odd especially if I take in consideration that most of the Turkish people I know couldn't speak too good English).

The flight to Dubai was scheduled for 16:45 in the afternoon, so 40 minutes earlier I and Krasi went again through the metal scanner again and thanksfully this time we were not searched for guns and bombs by airport police.
 

Emirates Company Logo

The airplane, we flied with was Boeing 777 – really a beatiful flying machine. We were lucky to travel with two other Bulgarians Nikolay and Gergana, who were flying to Chennai India for some kind of personnel training of some company personnel for the company http://Yazaki.com (an international company producing vehicles components) .

Emirates Boeing 777 nice airplane

Emirates airlines's organization service and convenience was really incredible! Emirates has done a great, job really. I had a lot of fun in the airplane in the flight, as they had every passenger sit with a touch screen display computer with a joystick similar to the ones with playstation.
< img src="https://www.pc-freak.net/images/emirates_passenger_personal_touchscreen_computer_Boening_777.jpg" alt="Emirates Boeng 777 Passenger personal computer touch screen device" />
A Boeng 777 Passenger seat view , the passenger touch screen device mounted on seats back

The little touch screen computer had a number of capabilities the passenger could watch a movie, get information about Dubai play his favourite old fashioned games like Pong, Asteroids, Galaga like, Checss, Arkanoid and like 10 outhers of classic games I know from my childhood.
Besides that the passenger's flight personal computer was equipped was even capable to make satellite phone calls chargable directly from VISA or Mastercard Debit or Credit card. The telephone was embedded with the joystick, so on the back of the control device joystick one has the satellite phone, the phone had the capability to call passengers who are inside the plane. To call another traveller inside the airplane you just need to have the passenger seat number.
As a computer security hobbyist, I've noticed one major problem with the phone calls in between airplane travelling passengers.
By default each sit's phone was sett upped to automatically answer phone calls from other passengers, Which means that if I'm a malicious abuser I can easily just call random people in the airplane and do social engineering pretending to be the plane Commander, stewardess or any other personal from the plane crew 😉
On the other hand calling random people, by getting advantage of how the system "hole", could easily give you the opportunity to make yourself random friends or share contacts with people from around the world 😉

Another handy thing about the onboard touch screen computer, I've noticed is the possibility to listen music from a list of a huge database with music. Also a huge database like (300+) movies ready to be seen was available, as well as some serials and some popular podcasts as well as the device even supported e-mail check and some basic internet functionalities (which unfortunately had to be used only after payment with a debit or credit card :|).

Emirates Passenger personal computer touch screen incredible device

In the middle of the 4 hours and 15 minutes flight, we were handed in a good portions of dinner meals, which obviously was properly selected to be suitable to be easily digestable and vitaminous food. Also alcohol arabian Coca-Cola, Coffe and tea was offered.

Before the meals was handed in by the few stewards in the airplane, each passenger was handed with a (hot) towel, to carefully clear his hand or face!

Many of the Arabs used the towels to wipe their face sweat, where europeans tended to clean up their hands (probably shows something about the each about arabian and european habits and culture?).

Dubai side view from the airplane before the landing was really amazing, I've never seen so much light concentrated on one place never ever in my life, landing went pretty smoothly thanks God, though it felt a bit more risky than the landing done by the Turkish airlines, pilots.
Maybe there is difference in the landing because it was done during night time and probably landings in night time a way difficult task for the pilot.

Just like in Istanbul, after going down from the plane, via the plane step-ladder we were transported to the Airport with Buses (I was told by Krasimir that, the bus transportation is used becuase, it's a way cheaper than using the equipment for "hot tie" to connect the plane with the terminal via "tuble".
Also maybe its difficult in terms of parking the airplane as the airplane has to drive like 1.5, 2km and park this is an astonishing amount of petrol plane fuel 😉

Anyways just to sum-up my first flight with Emirates/Skywards it was more than enjoyable and nice, everything from the plane take off through the overall airplane experience to landing felt like a veery well crafted, organized and stricktly managed process. It felt like verything happening is perfectly tuned, again really nice feeling 😉
Interestingly inside th airplaine they had a stewardesses which were either Malaysian or Indonesian. The reason for tat was probably because Arabs are crazy about chineese and the variations of yellow races as I've heard from Baky (an Egyptian) as well as from some few Egyptian colleagues I had.

After we went down from the bus transporting us to Dubai's terminal arrival terminal 3, which I think is the only terminal dedicated for visitors in Dubai, we couldn't freely anter Dubai, but we were supposed to go through a biometric security measure the airport here implemented few years ago an Eye Scan .

Dubai Airport Arrival in United Arab Emirates - Airport Terminal 3

The organization on the airport and the information that we were supposed to have the eye scan in order to enter Anyways after some questioning near few of the airport desks and offices, we found or way to the device place where the eye scans took place.

The eye scan process is quick and not that scary as it sounds, they ask you sit on a chair cover left eye, then cover right eye and open the eye widely to make a picture of the iris, then based on some algorthim for interpreting the data and through a complex IT develoepd system a check is done against a database of well known criminals and if no match is found you're given a seal which lets you in Dubai.

The only concern, I have is once they took your eyescan they have this information stored so basicly they have your biometric data and if the information is stolen or send to third parties you can never know, but that's how it goes you know it's life, if you don't do the eye scan you can't go in.
You don't have the option to just choose if you want to have the eye scan or not … My company boss tried to cheat them and walk through inside Dubai without ahe eye scan as he said he went through the eye scan so man times, but still he was obliged to go through the eye scan in order to be let in the city.

After the eye scan on the airport, we had to line up on a long line with arriving people waiting for being let in Dubai, show the copy of the visa with the eye scan seal to airport police officer. He checks the seal the visa, the international passport and then one is asked to stay in front of another camera snd they take a picture of him, once again a security measure …
This is just crazy, I understand that security is important but the measures implemented today on airports are inhuman and even abusive, not to mention they break any privacy one can have in today's world … I'm even scared to think about how a security check on an airport will look like 20 years from now.
Anyways after all the aforementioend checks we were FINALLY allowed to enter Dubai, what first striked me was the size of the buildings, its the first time in my life I've seen a buildings of this amazing size, just incredible!
Also all the buildings are all in color lights and are flashing like spaceships, probably requirement to make sure no airplane tries to land over some of the buildings at night time 😉

Roland, a part time tech consultant for Cadia Holding and a colleague, took us up from the airport and drove us to the hire apartment in Jumeirah Beach, Rimal 6 – ap. number 53, where we're currently settled.

Jumeirah Beach Residence Rimal
Jumeira Beach Rimal buildings

I'm very thankful Roland was there otherwise if we were supposed o pick up a taxi, they would have charged us at least 80, 90 EUR! for bringing us to the apartment.
The prices of transportation here and in general prices are a killing onse. I guess this is pretty normal especially if you consider the countless amount of money invested in Dubai.
Honestly Dubai looks like a paradise on earth, everything is amazingly well organized, as well the technology involved everywhere is on a perfect and a better level than almost everything, I've seen in Holland, Germany and probably almost every other of the Western Europe countries.

Something strange that took my attention here was that in every big mall or big store, they have a special prayer room, which are suited for pracicing muslims to do they're 5 times daily prayers 😉
Here in Dubai I was shocked to see many of the native arabic ladies to be completely wrapped up inside mostly black dresses, where the man were often dressed in a complete dress without a zipper called thobes as well as a sort of a hat like long veil very similar to our orthodox christian priest monks viels.

Dubai man with Thobes in order smiling ;) Dubai man with Thobes lined in order smiling

The veil like dresshing the man wears has a ring on top of the head which has some kind of muslim symbolism probably I'm not aware of. An interesting thing, I've found out here is that this veil for the hat has colors, if it's red this means it's Saudi Arabia a white one means usually the man is from Dubai and the nearby regions o something like that.

When we went out of the airport here the temperature difference was killing it was like 35 Celsium degrees at 21:00 o'clock night time!!

I'm actually lucky to come here in Autumn, temperatures on Autumn are acceptable at night it's like 20-25C and in day usually 35-40C.

The private apartment, where we're accommodated is amazing, it's big like a place, it has everything a flat TV, wireless internet, 2 bathrooms, 4 bedrooms etc.
To enter the buillding one needs to use his special ID card which is secured by a bar code, which has to be tagged on a bar code reader on the building entrance door.
Dubai itself seems more international at times, even than Western europe, you can see everything in Both English and Araabic, so you can understand basicly everything. Everyone speaks from the lowest employee to the office workers an acceptable English and thus communication is not a constraint like in Holland, where many people speak English which is too much influenced by German and german lingual structure.

I'm very thankful to God for blessing me to come to this nice place, now I'm laing over a nice coach and blogging.
By so far, I've seen two of the biggest Dubai Malls and some general architecture, all is collosal in size and reall amazingly built. I've heard from people quality of buildings is not that good as everything is being built in too short time and with cheap materials and by Indian labours who earn like 5 dollars a day. I'm not sure though how truthful is this as I think the quality of the apartment, we're accommodated is great.

Each room is equipped with a Clima, so the temperature inside is steady 22- 24C degrees. The body shock when you go out hence is really severe as usually there is like 10 or 15C degrees difference in temmperature.
Climas are, good but they create too much noise at night it's a bit noisy, but maybe with time one can get used to it.
The cars I saw here in Dubai are amazing, all the cards are really really expensive maybe the cheapeast car in Dubai worths no less than 10 000 o 20 000 EUR.
Euro, Dollars and the official UAE currency dirham are accepted everywhere in shopping malls and food stores and this is really nice.
The taxi drivers charge normal prices here, I was out with Jure and we took taxi few times and each time for like 5-7 km distance, the taxi charged approximately 30 AED per drive.
Random Taxi in Dubai

The Taxis are all luxurious cars with a (airconditioners) climas, it seems they have a metro already operating here as well as comperativfe cheap transportation with buses, but I'm not sure if something could be really cheap here 😉
Everywhere I went here I can notice something really beautiful in terms of either mostly modern design with arabic elemnts or technology. The elevators here are really quick. To go to the last stage of the 36 stages building here in Dubai it tooks the elevator no more than 1 minute 😉
The food here in Dubai seems decent, though its not that good like naturally grownned products or a chicken or cow who was rised in a private farm.
Anyways the food here in United Arab Emirates seems to be way better than the food in Holland and Germany, where it is a bit like plastic.
I don't know if its because of the Sun excessive warmth, God's grace to me or what but I should mark, here in Dubai and maybe in rest of UAE one feels warmer than in Western Europe.

People don't smile too much here especially the people who work on the lower levels of job, clear indicator that they don't earn good money.
I like that they don't smile too much as this reminds me in Bulgaria, where you can see sour faces a way more often than a smiled one.
Here people look a bit less soury than in Bulgaria.

I will be in Dubai 6 more days, so I'll have a clearer picture in my head about the place after some few days. Nevertheless from what I've seen so far, I'm really very amazed and very thankful to God to leeting me see all this new interesting things and culture.
I should take the time to find and take a look in the more traditional places here. Pitily globalization is seriously destroing the local people culture here, and you can't feel the real culture besides the arabic kind of dress, the mosques , prayer rooms and some entwisted muslim architecture with the modernistic buildings.
It will be very nice to see some real camels, elephants or some typically arabic kind of things 😉

Summing it up, the overall atmosphere here, the organzation of thingsm the business climate and infrastructure is something we europeans should learn from.

Disabling PHP system(); and exec(); functions to raise up Apache security on Debian GNU / Linux

Wednesday, July 18th, 2012

Disabling PHP system(); and exec(); functions to raise up Apache security on Debian Gnu / Linux

At security critical hosts running Apache + PHP based sites it is recommended functions like:

system();
exec();shell_exec();.....

to be disabled. The reason is to mainly harden against script kiddies who might exploit your site/s and upload some shitty SK tool like PHP WebShell, PHP Shell and the probably thousands of “hacker” variations that exist nowdays.

In latest Debian stable Squeeze, suhosin – advanced protection module for php5 is being installed and enabled in Apache (by default).
Simply disabling a number of functions using suhosin, could prevent multiple of future headaches and hours of pondering on who 0wn3d your server ….

Disabling the basic PHP system(); and other similar functions which allows shell spawn is not always possible, since some websites or CMS platforms depends on them for proper runnig, anyways whether it is possible disabling ’em is a must.
There are two ways to disable system(); functions; One is through using /etc/php5/apache2/conf.d/suhosin.ini and 2nd by adding a list of functions that has to be disabled directly in Website Virtualhost file or in apache2.conf (/etc/apache2/apache2.conf;
For people hosting multiple virtualhost websites on the same server using the custom domain Virtualhost method is probably better, since on a global scale the functions could be enabled if some of the websites hosted on the server requires exec(); to work OK. In any case using /etc/php5/apache2/conf.d/suhosin.ini to disable system(); functions in PHP is less messy …

1. Disabling PHP system(); fuctions through /etc/apache2/apache2.conf and custom site Vhosts

Place somewhere (I prefer near the end of config);;;


php_admin_flag safe_mode on
php_admin_value disable_functions "system, exec, shell_exec, passthru , ini_alter, dl, pfsockopen, openlog, syslog, readlink, symlink, link, leak, fsockopen, popen, escapeshellcmd, apache_child_terminate apache_get_modules, apache_get_version, apache_getenv, apache_note,apache_setenv,virtual"

Disabling it for custom virtualhost is done by simply adding above Apache directvies (before the closing tag in /etc/apache2/sites-enabled/custom-vhost.com

2. Disabling PHP system();, exec(); shell spawn with suhosin.ini

In /etc/php5/apache2/conf.d/suhosin.ini add;;

suhosin.executor.func.blacklist =system, exec, shell_exec, passthru, ini_alter, dl,
pfsockopen, openlog, syslog, readlink, symlink, link, leak, fsockopen, popen,
escapeshellcmd, apache_child_terminate apache_get_modules, apache_get_version,
apache_getenv, apache_note,apache_setenv,virtual

To do it directly via shell issue;;;

server: conf.d/# cd /etc/php5/apache2/conf.d/
server: conf.d# echo 'suhosin.executor.func.blacklist =system, exec, shell_exec, passthru, ini_alter, dl,' >> suhosin.ini
server: conf.d# echo 'pfsockopen, openlog, syslog, readlink, symlink, link, leak, fsockopen, popen,' >> suhosin.ini
server: conf.d# echo escapeshellcmd, apache_child_terminate apache_get_modules, apache_get_version,' >> suhosin.ini
server: conf.d# echo 'apache_getenv, apache_note,apache_setenv,virtual' >> suhosin.ini

Then to re-load the memory loaded Apache libphp library an Apache restart is necessary;

server: conf.d# /etc/init.d/apache2 restart
Restarting web server: apache2 ... waiting .
server: conf.d#

Tadam, this should be quite a good security against annoying automated script attacks. Cheers 😉

How to count lines of PHP source code in a directory (recursively)

Saturday, July 14th, 2012

Count PHP and other programming languages lines of source code (source code files count) recursively

Being able to count the number of PHP source code lines for a website is a major statistical information for timely auditting of projects and evaluating real Project Managment costs. It is inevitable process for any software project evaluation to count the number of source lines programmers has written.
In many small and middle sized software and website development companies, it is the system administrator task to provide information or script quickly something to give info on the exact total number of source lines for projects.

Even for personal use out of curiousity it is useful to know how many lines of PHP source code a wordpress or Joomla website (with the plugins) contains.
Anyone willing to count the number of PHP source code lines under one directory level, could do it with:::

serbver:~# cd /var/www/wordpress-website
server:/var/www/wordpress-website:# wc -l *.php
17 index.php
101 wp-activate.php
1612 wp-app.php
12 wp-atom.php
19 wp-blog-header.php
105 wp-comments-post.php
12 wp-commentsrss2.php
90 wp-config-sample.php
85 wp-config.php
104 wp-cron.php
12 wp-feed.php
58 wp-links-opml.php
59 wp-load.php
694 wp-login.php
236 wp-mail.php
17 wp-pass.php
12 wp-rdf.php
15 wp-register.php
12 wp-rss.php
12 wp-rss2.php
326 wp-settings.php
451 wp-signup.php
110 wp-trackback.php
109 xmlrpc.php
4280 total

This will count and show statistics, for each and every PHP source file within wordpress-website (non-recursively), to get only information about the total number of PHP source code lines within the directory, one could grep it, e.g.:::

server:/var/www/wordpress-website:# wc -l *.php |grep -i '\stotal$'
4280 total

The command grep -i '\stotal$' has \s in beginning and $ at the end of total keyword in order to omit erroneously matching PHP source code file names which contain total in file name; for example total.php …. total_blabla.php …. blabla_total_bla.php etc. etc.

The \s grep regular expression meaning is "put empty space", "$" is placed at the end of tital to indicate to regexp grep only for words ending in string total.

So far, so good … Now it is most common that instead of counting the PHP source code lines for a first directory level to count complete number of PHP, C, Python whatever source code lines recursively – i. e. (a source code of website or projects kept in multiple sub-directories). To count recursively lines of programming code for any existing filesystem directory use find in conjunction with xargs:::

server:/var/www/wp-website1# find . -name '*.php' | xargs wc -l
1079 ./wp-admin/includes/file.php
2105 ./wp-admin/includes/media.php
103 ./wp-admin/includes/list-table.php
1054 ./wp-admin/includes/class-wp-posts-list-table.php
105 ./wp-admin/index.php
109 ./wp-admin/network/user-new.php
100 ./wp-admin/link-manager.php
410 ./wp-admin/widgets.php
108 ./wp-content/plugins/akismet/widget.php
104 ./wp-content/plugins/google-analytics-for-wordpress/wp-gdata/wp-gdata.php
104 ./wp-content/plugins/cyr2lat-slugs/cyr2lat-slugs.php
,,,,
652239 total

As you see the cmd counts and displays the number of source code lines encountered in each and every file, for big directory structures the screen gets floated and passing | less is nice, e.g.:

find . -name '*.php' | xargs wc -l | less

Displaying lines of code for each file within the directories is sometimes unnecessery, whether just a total number of programming source code line is required, hence for scripting purposes it is useful to only get the source lines total num:::

server:/var/www/wp-website1# find . -name '*.php' | xargs wc -l | grep -i '\stotal$'

Another shorter and less CPU intensive one-liner to calculate the lines of codes is:::

server:/var/www/wp-website1# ( find ./ -name '*.php' -print0 | xargs -0 cat ) | wc -l

Here is one other shell script which displays all file names within a directory with the respective calculated lines of code

For more professional and bigger projects using pure Linux bash and command line scripting might not be the best approach. For counting huge number of programming source code and displaying various statistics concerning it, there are two other tools – SLOCCount
as well as clock (count lines of code)

Both tools, are written in Perl, so for IT managers concerned for speed of calculating projects source (if too frequent source audit is necessery) this tools might be a bit sluggish. However for most projects they should be of a great add on value, actually SLOCCount was already used for calculating the development costs of GNU / Linux and other projects of high importance for Free Software community and therefore it is proven it works well with ENORMOUS software source line code calculations written in programming languages of heterogenous origin.

sloccount and cloc packages are available in default Debian and Ubuntu Linux repositories, so if you're a Debilian user like me you're in luck:::

server:~# apt-cache search cloc$
cloc - statistics utility to count lines of code
server:~# apt-cache search sloccount$
sloccount - programs for counting physical source lines of code (SLOC)

Well that's all folks, Cheers en happy counting 😉

Richard Stallman explaining Why IPads and Cell Phones are bad for freedom

Wednesday, July 11th, 2012

It is a public secret that Mobile Phones which does us very good and generally makes our daily lifes way easier are also a big enemy to our natural ihnibited freedom. Life has become such that it is almost inevitable to do any business or do a daily simple jobs without using Mobile Phone. There is almost none practically today that has wilfully rejected to use the mobile phone on any basis, almost anyone except some strangers like Richard Stallman and probably few others security freaks.

I've been shocked to find out the Father of Free Software (Richard Mathew Stallman), well known in the hacker dome as RMS does not own and didn't use any mobiles. The concerns he pointed are very much logical and rightful. Owning a mobile is a great security hole in personal privacy (mobile phones can be easily sniffed by Mobile Operators) as well as anyone wearing a mobile can be tracked up to 5 to 2 meters to the exact location where he is based on the mobile phone cells to which the mobile is connected.

Many people are not aware actually of the severeness of the issue of constant tracking of people everywhere through this call "goodies". Many mobile operators are already running a software which is building place behaviour patterns of every user of their mobile network. In other words, as we're used to bring and use the mobile everywhere in automated program is creating a map for each number assigned in some of the mobile operators. The gathered data about our location going habits can then be easily used as a indicator for predicting our future behaviour, bying habits (how many times we go to super-market), how many times we go to cinema, what kind of interests we hold etc. etc.
This combined with Google, account monitoring could possibly create a system similar to the old movies Big Brother, where all people goods and even attitudes or desires is monitored, influenced and controlled ….

The severeness of the future implications of this constant "personal surveillance and tracking device" as Stallman use to call it is very dangerous for our freedoms.

I tried to live without a mobile phone, just like Stallman for about months, and to tell you the truth the world around seems completely different when you decide not to use 'em. The time I lived wihtout a mobile, clearly show me we have come to the point we cannot any more live without GSM. We fall the trap of dependanding the little "talk box" communication for absolutely everything, obviously sacrificing privacy and freedom for convenience.
Mobiles are just one side of the coin, as the non-free software which is ruling the software market and the use of computers puts another treat and takes away many foundamential freedoms we used to have in the less technological world.

Apple as a vendor of software and hardware also denies and breaks our freedom very badly, as the company tracks everyone who owns anything created by apple connected to the internet. Besides that non-free software producers, could change the user software with a press of a button giving them the opportunity to decide what is good and bad for us, leaving us at a state of a helpless dependable users.

The topic of technological little-by-little enslavement, we're going through nowdays and the denying freedoms, we experience while being convinced by companies that we became more free by each next mambo-jambo gadget or by owning the latest smart-phone is very huge and complex but unfortunately underseen in society. I don't understand why, is it due to the low technical skills of mass users is it due to a "not-care what will happen in future" attitude, but obviously people openly discussing or protesting the technologization taking away our freedom is almost zero ….

Here is the video I found in youtube in which Stallman is asked few, questions on Ipads (IBADS) and Mobile Phone use. I believe his short explanation synthesizes the problem quite well ;;;;

I just wonder after you check the video, Would you still accept an Ipad as a birthday gift ? 🙂
Do you still think cell-phones are "good" freedom safe and reliable ?

The lack of sharing in modern world – One more reason why sharing Movies and any data on the Internet should be always Legal

Saturday, July 7th, 2012

Importance of sharing in modern digital society, sharing should be legal, Sharing caring
 I've been thinking for a lot of time analyzing my already years ongoing passion for Free Software, trying to answer the question "What really made me be a keen user and follower of the ideology of the free software movement"?
I came to the conclusion it is the sharing part of free software that really made me a free software enthusiast. Let me explain ….

In our modern world sharing of personal goods (physical goods, love for fellows, money, resources etc.) has become critically low.The reason is probably the severely individualistic Western World modern culture model which seems to give good economic results.
Though western society might be successful in economic sense in man plan it is a big failure.
The high standard in social culture, the heavy social programming, high level of individualism and the collapsing spirituality in majority of people is probably the major key factors which influenced the modern society to turn into such a non-sharing culture that is almost ruling the whole world nations today.

If we go back a bit in time, one can easily see the idea and general philosophy of sharing is very ancient in nature. It was sharing that for years helped whole societies and culture grow and mature. Sharing is a fundamental part of Christian faith and many other religions as well and has been a people gathering point  for centuries.
However as modern man is more and more turning to the false fables of the materialistic origin of  man (Darwininsm), sharing is started seeing as unnecessary . Perhaps the decreased desire in people to share is also the reason why in large number people started being  self-interest oriented as most of us are nowadays.

As we share less and less of our physical and spiritual goods, our souls start being more and more empty day after day. Many people, especially in the western best developed societies; the masses attitude towards sharing is most evidently hostile.
Another factor which probably decreased our natural human desire to share is technocracy and changing of communication from physical as it used to be until few dacades to digital today.

The huge shift of communication from physical to digital, changes the whole essence of basic life, hence I believe at least the distorted sharing should be encouraged on the Internet (file movies and programs sharing) should be considered normal and not illegal..
I believe Using Free Software instead of non-free (proprietary) one is another thing through which we can stimulate sharing. If we as society appreciate our freedom at all  and  care for our children future, it is my firm conviction, we should do best to keep sharing as much as we can in both physical and digital sense.

Color Psychology – Color Mind Programming or how big companies boost their sales and make up your mind

Thursday, June 21st, 2012

Colors Programming Color mind Programming, how big companies boost their sales and make up your mind

As I've pointed earlier there is plenty of "secretly" kept and less known by public research on how colors influence us daily. The biggest companies are heavily taking advantage of what is found and known for colors impact on our minds (psyche). Actually there is a whole branch in psychology which deals with impact of colors perception on us.Besides companies, many modern governments are well aware of the many facts on how citizens percept colors and use this in color 'installment' in government offices and government institutions.

There is no universal knowledge on how colors completely affect us as every human on earth is very unique and saying this or that color has this or that impact on indivirual or group is not 100% accurate. However there are general traits nowdays formed especially with globalization and unification of TV ads and big companies corporate image, a unification started on how different nationality people perceive colors.

Nowdays in developed countries there are more and more people who perceive certain colors in similar fashion. Therefore every serious top marketer should carefully study colors and their relation with ancient time people believes and understanding on what each of the 'rainbow' colors symbolize. Most likely because there is no completely unified understanding of colors between various individuals may companies like Google and Microsoft started using all the rainbow colors in their basic company logos and branding for more on this topic please check my previous blog post Color trick Microsoft and Google use to keep their users loyal

Another large industry area, where color programming is very heavy is Computer and Video Games. You certainly still remember large portions of the games like Sega’s Sonic the HendgeHog or Mario Super Bros. or even the old arcade machines with games like Punisher or Cadillacs and Dinosaurs, Street Fighter etc.
All this old arcade games have a big portion of Color programming embedded in and this is one of the main reasons we remember them for a long time and playing them evoked such a strong feelings in youth.

This trend of using colors to make up our minds is being observed for many other physical goods as well as is starting to get more and more heavy adoption by websites branding on the internet.
Actually those with most succesful businesses on the internet have already integrated some kind of color programming scheme. An example for this would be the Internet top domain names seller GoDaddy. The have adopted a green scheme as a primary color combined with some other ones to create in the customer a feeling of ecology, naturality, peace and solitude.

The study of color programming is one major field to be known by anyone truly willing to understand why certain big store chainslike Carrefour, Lidl, Billa, MediaMarkt – in western europe or TechnoMarket, TechnoPolis (MediaMarkt copied tech equipment by shops here in Bulgaria) are decorated inside the way they are. I personally didn't like the concept of color programming since from Spiritual point of view it is a big evil. Trying to manipulate people perception to do something you would like to in general is very evil from spiritual point of view. A mixture of rainbow colors in a natural environment for example flowers in the wood or wild mountain place is one thing, but making it artificial and placing it in certain pre-desired order is totally another. Besides that the colors in the natural environment are natural and therefore the impact on us even if colorful is very much better than if it is done with a certain intention like in the big supermarkets stores, fast just food companies – McDonalds, Burger King etc.

The research on color mind influcence – Color mind programming is a controversial science. Nowdays many big businesses however use this as a granted science, even whole business sects with some mambo-jambo believes universities, children garden and schools in modern countries have employed the use of some type of color programming aiming to influence their pupils, students (organizational members – you call it).
Color mind programming and heavy use on advertisements on the TV, the Internet, Stores and mostly everywhere are however starting to took their tolls. The high increase in mental problems and dumbness in developed and some undeveloped countries as well as the increased number of people who go insane because of too much color programming is reality. The believe that mental programming is one of the ultimate tools to influence somebody and push him to do things you want like consome more of a product or generally consume (buy) more goods creates another severe issue it makes people to constantly over-consume (eat more than the body needs) and this increases the number of over-consumption evoked diseases …

But color programming doesn't stop with just the material (physical) surrounding world it is a concept highly employed in online based marketing. Online business is seen on so many top used websites, social networks like take for instance (facebook). It is so spread that even the software primary vendors like Microsoft, search engines Google Inc. have already heavily employed the color programming as a basis of their products.

There is another reason why most vendors nowdays issue their physical or 'virtual' products so colorful using all the colors of the rainbow. The reason is the fact that as a kids through animation, cartoons, toys and surrounding environment we have been exposed already even from our very youth age to a kind of color programming through kids toys we've been given by our parents). Hence the young years color programming became a basis for a future time color programming. The colorfulness of our kids years are already sub-consciously stored in our minds, so almost naturally there is a feeling of joy to pop-up once we see something childishly colorful.

Color Trick Microsoft and Google use to keep their users loyal and happy unwalfully

Tuesday, June 12th, 2012

Color mind influence has been longly researched. It is researched and there are some findingings on how we people react on colors. This researches are not much known and most of them are not put on the internet (??) One model claiming to have explained how colors influence is called HBDI – Herrmann Brain Dominance Instruments.

In the picture beginning of this post, I have presented a quick "Personal Profile" of HBDI on how one think in order to determine in "which colors" one tends to think more ___

In short HBDI model claims to explain how people think in another model.
My personal view of it is it is like most science nowdays more based on faith than on a clearly conducted scientific research and facts. We know pretty well many people tried to explain how brain operates and many people give models to explain it however none of the models could grasp in completeness the complexity of human brain. Hence Businessman people who use this model in their daily life and they push it to us has put the model in action not that they know it is working but rather they believe it does .., Saying this few words as introduction I will contninue onwards to explain you about HBDI as in the business world it is considered as a "Strategic Asset" for a company success. Hence the use of richest companies of the model has a serious impact on us the common people and unknowing (uninformed) computer users.

Some of the companies who integrated the HBDI to their models we all know are of course not strangely Microsoft and Google
;;;

Below I present you a picture showing the HBDI The Whole Brain Model |||

HBDI The whole brain model

Next I show you Microsoft Windows OS worldly "infamous" flag |||

Microsoft Windows OS Flag

You can see for yourself the basic color from HBDI WHOLE brain model are integrated in the Microsoft flag, only the order of colors present and the color gamma is different;;;;

The basic colors in HBDI model to explain how human brain works is separated in 4 segments as you can see from above screenshot. There are a number of tests one can do to determine what is his exact HBDI profile, and in abstract terms in which kind of colors he prefers to think.

There are a whole "army" of people involved into this sect like philosophy (I call it philosophy as surely every model that tries to explain everything is doomed to fail it is the nature in which God created the universe so complex and he put us be part of it and not controllers of it that any Universal model trying to explain it has never succeeded so far. The HBDI has some fruits for the only reason it is believed to work well by the people with money.

As you see in the colors HBDI claims there are 4 segments corresponding to four basic colors

  • BLUE
  • YELLOW
  • GREEN
  • RED

Each of the colors is an indicator on how the person tends to think the BLUE people as HBDI practicioners (believers) calls them are —

Analytical, Fact Based, Logal, Quantitative

The YELLOW oriented people are claimed to be —

Holistic, Intuitive, Integrating, Synthesizing

The GREEN ones in model terms are interested in —

Organizing, Sequentiality, Planning, Detailizing facts

Finally the RED Ones are said to be —

Interpersonal, Feeling based, Kinesthetic, Emotional

Now as you can understand this model though it looks like promising is based on a philosophy which rejects the existing of spirit realm God Angels or good or evil. It claims everything we're are or we want to be can be achieved following the HBDI to develop your own brain.

This model as every human made model however does reject the fact that besides internal factors and brains we're put into external environment most of which we cannot control and therefore even if we try our best to have certain goals and complete them the external uncontrolled facts can be a reason to stop us to complete our goals.

Now back to my point, that Google, Microsoft and probably many other products and physical goods are heavily using the HBDI color scheme ;;;
Here is the Google Inc. Logo the color trait of HBDI is there:

Google Search Engine Logo and HBDI 4 colors embedded

For those doubting that Google Inc. and Microsoft Inc. are along the false believers of HBDI color scheme brain ideology I present below the Logo of Google Web Browser =- Google Chrome

Google Web Chrome Browser Logo 4 colors HBDI microsoft flag

It is evident 4 colors used as a main ones in the HBDI tool are present in Google Chrome just like in Microsoft Windows logo flag, the only difference is in the order of colors.
Also it is interesting the name Chrome that Google Chrome took is most likely taken from Aldous Huxley's – Brave New World (A book depicting a short future highly conditioned society) , the book story line goes around a society programmed to do the things they do.

I assume it is very likely that Google's founders Sergey Brin or some of their subordinate working for Google are very much into the idea of conditioning people just like in the book and this is most likely the reason they choose the Chrome as a title for Google's browser ,,,

The 4 Colors from HBDI yellow, green, blue, red are embedded also in the google .ico file (the little icon showing in browser URL bar), below is a screenshot of a tab where google is opened showing the .ico image:

Google Icon 4 colors Linux Debian Epiphany Browser tab screenshot

Do you remember the good old Windows XP start button, have you noticed the Windows flag embedded in it, if not let me show you;;;

Microsoft Windows XP Start Button and HBDI 4 colors scheme

But wait the Windows flag placed on the left bottom of Ms Windows-es is not only on XP it is also on Windows 3.11 cover, Winblows 98, Vista, Windows 2003, Windows 2007 and actually all the M$ operating systems ever produced since the very early days M$ become a top OS producer :::

Windows 3.11 Operating system logo flag

Microsoft Windows 95 4 colors flag and blue sky

Here is also the 4 colored (a bit like Nazi like looking) flag on M$ Win-doze 7 |||

MS Windows 7 start Menu m$ windows well known flag

Also the Microsoft Flag is positioned on the bottom left screen on purpose. It is well known fact that most of the world (except Arabic) are used to read the text from Left to Right

, therefore it is natural for our eyesight to look for the text on the left side. I just wonder why they placed the START on the bottom and not on top. It is natural we read text and books from the most top to the most bottom ,,,.,

Even Apple Computers nowdays Macs has most likely used the HBDI as the main 4 colors and some gamma from rainbow colors are present on their Classical Apple Computer logo

Old Apple Computer/s logo colors of rainbow 4 hbdi colors are there

Makes me wonder if Jobs employed the HBDI model in his company. Well what is the reason for people loving so much this rainbow colors combination. If we think for a second outside of HBDI's brainwashing ideology for what each color would stand for. Well it is simple is comes from our young years most of the people between age 2 and 50 years has been more or less exposed to the so colorful Kids Cartoons, which are all so colorfully painted. Since our very early age we've placed in us a love for colorfulness outlook (well again not all of us for example I prefer less colors, I'm sure there are plenty of people who don't like the heavy colors we see in almost everywhere around us).

The problem with this 4 colors use on purpose and all this unnatural color placing everywhere is that it is unnatural and not in good synergy with our surrounding natural environment. Therefore I personally think using a colorful color paintings on everywhere in both computer programs and the physical world plays us a bad joke and is one of the reasons so many people are on the virge to get crazy nowdays and many have already had already cracked out.
