In case of development (QA) systems, where developers deploy new untested code, exposing Apache or related Apache modules to unexpected bugs often it is necessery to increase Apache loglevel to log everything, this is done with:
LogLevel warn is common logging option for Apache production webservers.
in httpd.conf is the default Apache setting for Log. For some servers that produce too many logs this setting could be changed to LogLevel crit which will make the web-server log only errors of critical importance to webserver. Using LogLevel debug setting is very useful whether you have to debug issues with unworking (failing) SSL certificates. It will give you whole dump with SSL handshake and reason for it failing.
You should be careful before deciding to increasing server log level, especially on production servers. Increased logging level puts higher load on Apache webserver, as well as produces a lot of gigabytes of mostly useless logs that could lead quickly to filling all free disk space.
If you would like to increase logged data in access.log / error.log, because you would like to perform versatile statistical analisys on daily hits, unique visits, top landing pages etc. with Webalizer, Analog or Awstats.
Change LogFormat and CustomLog variables from common to combined.
By default Apache is logging with following LogFormat and Customlog
LogFormat "%h %l %u %t "%r" %>s %b" common CustomLog logs/access_log common
Using Combined Log Format produces all logged information from CustomLog … common, and also logs the Referrer and User-Agentheaders, which indicate where users were before visiting your Web site page and which browsers they used. You can read rore on custom Apache logging tailoring theme on Apache's website
I've personally always hated super markets from the very early days I entered one. Here in Bulgaria we've been somehow partly lucky not to have supermarket due to the different philosophy of the communistic regime in which we lived until 1991. The philosophy of then governing communist back then was to distribute food in local middle size or small stores owned by the government. The food has to be approved by governmental body and heavily checked if it matches the governmental set standards. The variety of food we were offered in the stores was very little. Most of the small stores (which were owned by the government) only contained basic products like;;;
bread, youghurt, milk, meat, butter, lemonade, beer and few more,
This was done probably intentionally and was a result probably of our long years Orthodox Christian faith which (has saved us and preserved over the centuries). Orthodox Christianity has always teached for simplicity. Even though the communist party rejected the faith and even did severe persecution against the Bulgarian Orthodox Church. The people on the top elite who were planning the communism had been a descent of an orthodox christian raised up living and therefore the philosophy of simplicity was inherited (even genetically) so the way the COM party behaved based on its leaders and the governing decisions about the nations belonging to communism (Russia, (Yugoslavia) – Serbia Koso , Bulgaria, Greece, Egypt etc.) were in a material expression in conjunction with the Christian tradition of simplicity (i say material because Orthodox Christian Church even visiting back then in the countries was usually prohibited and the Com. party did their best to ruin up the believe in Christ in people).
In communism the local suburb grocery stores, were the only "points" of distribution of food. Since buying and owning a car took at least few years of waiting and big money for it. Not more than 10 to 20% of families owned car and owning a car was considered to be granted mostly to people belonging to the then governing communistic elite or the Communist Party.
The public transportation was encouraged because according to communism so called "geometry" which was a main drive for how the systems in communistic countries should work it was estimated public transportation is cheaper and more environmental friendly than if a car is given to anyone, also public transportation (trains, bus-es) etc. did a good thing in the aim of the party to exersice higher control and surveilance over the population.
Because of that existence of big super-market was scarce and the culture to go and buy from a shop with your own family car was not existing.
The equivalent of nowdays mall shops (big retail stores) was usually located on the city center and the size of this shop was much smaller and the variety of products one can find there was only few. Hence the customer didn't have so much options to choose between, neither had to spend too much of time on choosing, the com party wanted the people to work more and buy less, so spending time in stores was not encouraged.
With the entrance of democracy and the moving up of large super-market food and good retails shops like Metro was among the first ones which entered the "freed" market. It was really a bizarre experience for us the ex U.S.S.R belonging people to enter such a large sized stores and to face such a big variety of choice.
Before that in communism we never saw such stores even on the TV, since the TV was governed by communistic party and only information which was useful for the establishment and protection of the regime was projected on the only available National TV channel.
Sorry to distract a bit from the major topic of this post, but I thought this is necessery to explain before continuing because it is important to understand that unintentinonally the communist gave us an advantage to have a different view on things than Western free world, a view which is in many things contrary and more correct (in terms of hard logic) than to Western Europe.
My first encounter with a super-market was only about 8 or 10 years ago and I believe many people who lived in the province of Bulgaria and other ex-communist countries did for a first time experience super-markets approximate 10y. ago. Though all looked so nice inside the shop and the shop emploees were so nice I always felt something very cold dead inside this big stores. Ptonsnlu my intuition (spirit) if you want has always pointed me out that there is something very wrong with this super markets.
With the increase of products on the market for us people who lived up to our 8 to 12 years (young age) in communism it was a great shock, since we were raised in a society based on some communist false ideology and suddenly the markets were opened and the products variety to choose between become extremely high. All previously said to be good and true in communism time was said to be anti-freedom and many people did their best to destroy as much as possible mostly everything somehow connected with previous communistic time. My homeland Bulgaria as a result of this become a very hard to live place and we were forced to adapt in fast paces and learn things on how we have to live like democrats for a very little short of time. One severe "damage" most of the growing people in Bulgaria in communism had was the hardness and inability to make choices. For many people between the age of 25 to 35 it is very hard to make choices even for small things. This was a direct consequence of a long years (45 years) of communist propaganda, and few generations who lived in a non-freedom respecting regime which conditioned and prepared a specific plan and place for every individual living in the country.
Seeing communism as the ultimate evil and manipulation to make us dependent we didn't know that in the free democratic world the manipulation and conditioning in society was heavy too.
"The Programming" of western society through institutions, stores and order in society was a fact and in a sense the only difference between the Democratic world and communistic world was one of the worlds seemed to have a larger frame in which the individual can work and live, whether the communistic regime seem to be more restrictive. One main thing used to condition people choices and buying behavior and make them over-consume to make the democratic economy constantly growth was big super-markets. Though they were privately owned and not like in communist country, the only drive behind each shop was PROFIT, PROFIT and agian PROFIT.
Higher profits would mean higher consumptions, higher consumptions means higher production and more work places opened as well as more expenses for working individuals would mean bigger necessity to work more and earn more, because though the sallaries incomes were high in the free world. The individual necessities there were even increasing too.
Since the about 1950s 1960s the super-markets started entering the "free" democrat countries world. As a result the small shops which were prior a main food and beverage distribution source started closing, because they couldn't be a concurrence to the big "brothers" super-markets which were able to buy higher quantities of goods in lesser price and therefore sell many of the goods in much lower prices than the little grocery stores.
The result with the years was a huge shift in people buying behavior from local groce and open markets to buy everything from the big super-markets. The big store chains had to be in a fight for customers all the time, so businesses involved started customer wars and tried their best to "steal" customers from each other. In this financial wars a main thing that most super-market chains and malls did was constant optimization of efficiency of both buying and reselling to the end customer. This is a 3 step business process actually.
1;;; They buy from the commodity producer 2;;; They prepare the food for the store (packaging, cleaning up whatever) 3;;; They put it in a certain way in the store and organize the store in a way to always sell more and more
As a result a huge number of tricks were employed by each and every super-market aiming to deceive the customer to ever buy more The deception of the client in store is very tricky and smart organized so it cannot really be called a lie but its rather a tricky smartness.
Since the super-markets entered in my country too and the tiny grocery stores are mostly closing unable to compete with the large super-market 'money making machines'. Even I am sometimes forced to buy stuff from super markets. Since here in Bulgaria the culture of purchasing from super-markets is not so strong yet. In order to be able to consume the little grocery stores. Many large super-markets started investing in making the little groceries their retail shops with their brand or (sometimes a new make up brand). By doing so the little grocery stores loose their authoritarity and independance and become dependant on the big super-market on the type of products they will sell, this obviously means this strategy of the big super-market in the long run will lead the little grocery stores we still have to ruin up. This is obvious because if the small grocery stores start selling the exact same products (brands) of the big super-markets, there will be nothing left to make the little grocery unique. Neither the variety of products choice inside or pricing will be any different from super-market. This will mean the tiny grocer will be no different from the big super-markets in terms of product and prices and therefore. The clients which now are loyal to small grocery stores like me will then have not such big motivation to buy from small super-markets, since everything inside is somehow similar (not to say) the same as with big supermarket the only difference would be the lesser variety which is obviously a good reason why the customer would definitely prefer to buy from the large supermarket …
On the videos you're about to see below, they explain some of the probably thousands of tricks nowdays existing the super-market chains employs to trick us to exponentiolly consume their goods.
Old Tricks of the SuperMarket Trade
As you can see the video is presenting a reality of the tricks which was used in the 1960 and now technology and knowledge in the field has largely increased and since they there are surely many new trick 'developments' which are working for the masses of customers daily. There is even a whole science centered on buying behaviour already existent called buyology!
Here is a short introduction to buyology to give you an idea what its purpose is:
Short introduction video on buyology – The Science of buying part 1 of 2
Short introduction video on buyology – The Science of buying part 2 of 2
Seeing all this is very precious information, since being informed one can escape the bad "tricks and traps" pawn in the markets.
All the information about the communistic regime and the 'shopping system' there was mentioned priorly because I wanted to explain a bit of the difference of then and now to point you to my opinion that the Western buying model and expectation to sell more based on the tricks are probably not working very well here in the ex-communistic countries, especially with the older generations and the one like me which somehow grow a small part of their youth in communism.
The reason is we have a different 'social programming' than westerners. Also the different spirituality (The orthodox Christian faith) plays another role. Also there is a difference in the type of buying behaviour. In Bulgaria there is no culture to buy once or twice per week. People have culture to buy daily, though this is starting to change slowly these days.
The topic is actually very huge and I'm sure what I'm saying is just the 'tip of the iceberg'. As I'm a firm opponent of big industries and large business I'm firmly against the buying from big stores any goods. The reason is that simply by doing so one makes the already RICH people even more RICHER. By increasing the richness of a certain small group of people daily, we as society are un-consciously somehow involuntarily letting them increase the financial control that is already there in some degree to the society. As democracy's main drive is money this means that by helping the large business-es marge and become even BIGGER, we're doing something against ourselves and our interests as society. I don't think that any ordinary citizen in the free world want to live in a fully controlled one World State (one world country), similar to the ex-communism I lived through, so I think people concerned about our freedoms should oppose the big businesses according to the society level they're in. Even if we're not in position to change things with money, we as society are in a position to change ourselves and our understanding of world, our desires and our behaviour. If we change our value system in a way, where money are not a top priority and the highest value the outcome will be positive in both spiritual terms and overall world state.
The modern day however wants us to falsely believe that we're divided, helpless and money dependent. This is a big delusion which we're constanty repeated. Just like with the super-market this big super-market company owners were able to convince us through time that super-market is better than the grocery stores, because of the less money spending advantage. Even if in the past there were possibility to spend less via supermarket nowdays spending less by using the supermarket instead of the small groce-store is a BIG LIE. Even if one spends less in super-market on certain products, the amount of related products he is cheated* to buy in store highly exceed the simply money one would spend on even higher priced products in the small groce. The outcome results from the super-market is also a big waste, as I lived in the west I've seen most of the households are buying more than they need, spending more than they need, cooking more food and more frequently than necessery and throughing large portions of food in the garbage (e.g. a huge amount of food waster).
If it was possible that people were aware they are buying all this non-sense food because of deception, they would have bought less, the super-markets would bought less and distribute less and the food (waster) remaining could be distributed to poor-er countries to help the starving kids and suffering people in Africa. Helping the suffering and starving, we would have helped each other as it is a nowdays well known that even on molecular level the whole world is connected, therefore helping our poorer brothers and sisters is actually helping ourselves ***
This post will be short as I'm starting to think long posts are mostly non-sense. Have you people all wondered of barcoding? All world stores around the world have now barcoding. Barcode numbers regulations are being orchestrated by certain bodies, we people have no control over. Barcoding makes us dependent on technology as only technology can be used to read and store barcodes. It is technology that issues the barcodes. We have come to a point, where we humans trust more technology than our physical fellows. Trusting technology more than the close people to us is very dangerous. What if technology is not working as we expect it to? What if there are hidden ways to control technology that we're not aware of?
Technology concepts are getting more and more crazy and abstract. Thinks about the virtualization for a while. Virtualuzation is being praised loudly these days and everyone is turnning to it thinking it is cheap and realiable? The facts I've seen and the little of experience I had with it were way less than convicable. Who came with this stupid idea, oh yes I remember IBM came with this insane idea some about 40 years ago … We had sanity for a while not massively adopting IBM's virtualization bulk ideas and now people got crazy again to use a number of virtualization technologies. If you think for a while Virtualization is unreality (unexistence) of matter over another unreality. The programs that makes computers "runs" are not existent in practice, they only exist in some electricity form. Its just a sort of electric field if you think on it on a conceptual level … As we trust all our lives nowdays on technology, how do we know this technological stored information is not altered by other fields, how we can be sure it always acts as we think it does and should? Was it tested for at least 40 years before adoption as any new advancement should be. Well Of course not! Everything new is just placed in our society without too much thinking. Someone gives the money for production, someone else buys it and installs it and its ready to go. Or at least that's how the consumers thinks and we have become all consumers. This is a big LIE we're constantly being convinced in! It is not ready to work, it is not tested and we don't know what the consequence of it will be! Technology and Genetically Modified Food are not so different in this that they both can produce unexpected results in our lives. And they're already producing the bad fruits as you should have surely seen. You can see more and more people are getting sick, more people go to doctor more people have to live daily with medication to live a miserable dishealthy I wouldn't say live but "poor" existence … Next time they tell you new technology is good for you and will make your life better, Don't believe them! This is not necessery true. Though todays technology can do you good, In my view the harm seriously exceeds the good.
Are you a Debian System Administrator and you recently run apt-get upgrade && apt-get upgrade finding out there are plenty of new packagesfor upgrade? Do you need only a pre-selected number of packages to upgrade with apt? I run apt-get update && apt-get upgrade on one of our company Debian servers, just to see there are a number of packages to be upgraded among which there was some I didn't wanted to upgrade. Here is a little paste output from apt-get upgrade:
debian:~# apt-get update && apt-get upgrade Hit http://security.debian.org squeeze/updates Release.gpg ... Hit http://security.debian.org squeeze/updates/main amd64 Packages Fetched 128 kB in 0s (441 kB/s) Reading package lists... Done Reading package lists...

From first sight it seems logical to issue apt-get upgrade packagename to upgrade only single package with its package dependencies, instead of the whole group the above packs. However doing: apt-get upgrade imagemagick will still try to upgrade all the packages instead of just imagemagick and its dependency package deb libmagickcore3
debian:~# apt-get upgrade imagemagick Reading package lists... Done Building dependency tree Reading state information... Done The following packages will be upgraded: at imagemagick libdbd-pg-perl libfreetype6 libmagickcore3 libmagickcore3-extra libmagickwand3 libmysqlclient16 mysql-client mysql-client-5.1 mysql-common mysql-server mysql-server-5.1 mysql-server-core-5.1 14 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. Do you want to continue [Y/n]
Doing all package,upgrade is not a good idea in my case, since upgrading mysql-server will require a MySQL server restart (something which we cannot afford to do right now) on this production server. MySQL server restart during upgrade is never a good idea especially on productive busy (heavy loaded) SQL servers. A restart of the MySQL server serving thousands of requests per second could lead often to crashed tables and hence temporary server downtime etc.
Still it is a good idea to upgrade the rest of packages with their newer versions. For exmpl. to upgrade; imagemagick, at , libfreetype6 and so on.
In order to upgrade only this 3 ones and their respective package dependencies, issue:
debian:~# apt-get --yes install imagemagick at libfreetype6
Repeat the apt-get install command with passing all the single package name you want to be upgraded and voila you're done :). Be sure the apt-get install packagename upgrade doesn't require also upgrade of myssql-server, mysql-client, mysql-common or mysql-server-core-5.1 or any of the package name you want to preserve from upgrading.
I've recently had to make a copy of one /usr/local/nginx directory under /usr/local/nginx-bak, in order to have a working copy of nginx, just in case if during my nginx update to new version from source mess ups.
I did not check the size of /usr/local/nginx , so just run the usual:
Execution took more than 20 seconds, so I check the size and figured out /usr/local/nginx/logs has grown to 120 gigabytes.
I didn't wanted to extra load the production server with copying thousands of gigabytes so I asked myself if this is possible with normal Linux copy (cp) command?. I checked cp manual e.g. man cp, but there is no argument like –exclude or something.
Even though the cp command exclude feature is not implemented by default there are a couple of ways to copy a directory with exclusion of subdirectories of files on G / Linux.
Here are the 3 major ones:
1. Copy directory recursively and exclude sub-directories or files with GNU tar
Maybe the quickest way to copy and exclude directories is through a littke 'hack' with GNU tarnginx:~# mkdir /usr/local/nginx-new; nginx:~# cd /usr/local/nginx# nginx:/usr/local/nginx# tar cvf - \. --exclude=/usr/local/nginx/logs/* \ | (cd /usr/local/nginx-new; tar -xvf - )
Copying that way however is slow, in my case it fits me perfectly but for copying large chunks of data it is better not to use pipe and instead use regular tar operation + mv
# cd /source_directory # tar cvf test.tar --exclude=dir_to_exclude/*\--exclude=dir_to_exclude1/* . \ # mv test.tar /destination_directory # cd /destination# tar xvf test.tar
2. Copy folder recursively excluding some directories with rsync
P>eople who has experience with rsync , already know how invaluable this tool is. Rsync can completely be used as for substitute=de.a# rsync -av –exclude='path1/to/exclude' –exclude='path2/to/exclude' source destination
This example, can also be used as a solution to my copy nginx and exclude logs directory casus like so:
As you can see for yourself, this is a way more readable for the tar, however it will not work on servers, where rsync is not installed and it is unusable if you have to do operations as a regular users on such for that case surely the GNU tar hack is more 'portable' across systems. rsync has also Windows version and therefore, the same methodology should be working on MS Windows and good for batch scripting. I've not tested it myself, yet as I've never used rsync on Windows, if someone has tried and it works pls drop me a short msg in comments. 3. Copy directory and exclude sub directories and files with find
Find in collaboration with cp can also be used to exclude certain directories while copying. Actually this method is better than the GNU tar hack and surely more efficient. For machines, where rsync is not installed it is just a perfect way to copy files from location to location, while excluding some directories, here is an example use of find and cp, for the above nginx case:
This will find all directories inside /usr/local/nginx with find command print them on the screen, then execute recursive copy over each found directory and copy to /usr/local/nginx-bak
This example will work fine in the nginx case because /usr/local/nginx does not contain any files but only sub-directories. In other occwhere the directory does contain some files besides sub-directories the files had to also be copied e.g.:
# for i in $(ls -l | egrep -v '^d'); do\ cp -rpf $i /destination/directory
This will copy the files from source directory (for instance /usr/local/nginx/my_file.txt, /usr/local/nginx/my_file1.txt etc.), which doesn't belong to a subdirectory.
The cmd expression:
# ls -l | egrep -v '^d'
Lists only the files while excluding all the directories and in a for loop each of the files is copied to /destination/directory
If someone has better ideas, please share with me 🙂
I’m watching iGenius – How Steve Jobs changed the World movie. I heard about a movie from Alex a friend of mine who said this movie sheds some light on history of Apple Computers Inc, Macintosh and the great significance of Steve Jobs work as a manager and visionary to change the world for good. The world has suddenly been astonished by Steve Jobs sudden death so surely the interest about him is tremendously up.
I do respect Jobs as under his leading the computer industry has received some innovations, still I don’t agree with many of the movie aspects which turn Apple and the consequent company products IPhone, Ipad, Ipod etc. into a mega hype products. I’m being honest to myself and I should say many of the innovations they did are not something too much, but just a product which popularized or minituarized some older invented technology.
The product quality of Apple in the past is a fact so one cannot argue with this however with recent years I wouldn’t say the company quality is so much supreme as presented in the movie. What I don’t understand why is Jobs receiving so much praise and recognition but rarely somebody could show his bad sides as well. We’ve been again manipulatively mislead that he is a mega genius or like an angel on earth. However the achievements of Apple and the mass production and involvement of the field of marketing which lies basicly and makes profits based on great deceptions of Jobs doesn’t make Jobs to a super hero. As an enterpreneur and businessman his achievements are unquestionable but for many years now the reality of business is sad and a honest man could rarely be found to be dealing with business. Usually the people who like dirt, lies and fame are into business. Most of the times these are people who are ready to kill in the name of Public Recognition and Success. Jobs has been said to be a Buddhist according to what I’ve red in Wikipedia. If that is true its rather strange to me on fruits his buddhist faith produced. I don’t believe that any rational man who observes nowdays technology and how it is used doesn’t see the great harm technology did us and is continuously pushing us down. Buddhist teachings in my view teach on helping the neighbor educating and giving up things for free. Apple products however are not giving anything for free, yes some of them do education. Therefore in my view the philosophy of apple and its application is not really fitting up to helping the neigbor as they don’t come free of charge like the free software does. Apple products actually enslaved their users, all of apple products are nowdays connected to Apple’s Inc. Mega Corporation IStore or they report somehow to apple during updates or purchases more or less about users likings or behaviours. This obviously doesn’t respect users freedom and makes Apple an example of a company that doesn’t respect completely the user natural right of freedom and privacy.
To sum it up iGenius – Or How Steve Jobs changed the World is a highly manipulative movie just like most of the movies or books dedicated to super heroes are. Steve Jobs was lucky to get this recognition and status in life, however this doesn’t make him too much different from all of us. He just used to be in the right time in the right place and achieved what he did explicitly by God’s mercy. As a known fact Jobs was an Orphan and as we can see from many life examples God helps and has helped many orphans to have a good lives eventually.
Also I’m quite curious if Steve Jobs success was just a fruit of his good fortune or there were just too many circles of people behind him (Jewish or Masonry) possessing big fortunes who found it practical to sponsor his (??) products and ideas seeing a lot of potential to keep the world under siege through technology. Nomatter what the complete true behind Jobs and his achievements are, he is still an inspirational person and an “icon” in the field of IT. Even I’m a bit Jealous on his overall achievements. Anyways for people who want to loose some approximately 42:00 minutes on a hype Jobs praise movie and see some of apple’s products and pictures of Jobs and Apple / Macintosh products the movie is a good choice 😉
If you’re experiencing problems with maximising flash (let’s say youtube) videos on your Debian or Ubuntu or any other debian derivative. You’re not the only one! I myself has often experienced the same annoying issue.
The flash fullscreen failures or slownesses are caused by flash player’s attempts to use directly your machine hardware, as Linux kernel is rather different than Windows and the guys from Macromedia are creating always a way more buggy port of flash for unix than it’s windows versions, it’s quite normal that the flash player is unable to properly address the computer hardware on Linux.
As i’m not programmer and I couldn’t exactly explain the cause for the fullscreen flash player mishaps, I’ll skip this and right give you the two command lines solution:
This should fix it for, you now just restart your Icedove (Firefox), Epiphany Opera or whatever browser you’re used to and launch some random video in youtube to test the solution, hopefully it should be okay 😉 But you never know with flash let’s just hope that very soon the open flash alternative gnash will be production ready and at last we the free software users will be freed from the evil “slavery” of adobe’s non-free flash player! Though this tip is tested on Debian based Linux distributions it should most likely work same in all kind of other Linuxes.
The tip should also probably have effect in FreeBSD, though the location of the adobe directory and mms.cfg should probably be /usr/local/etc/adobe, I’ll be glad to hear from some FreeBSD user if including the OverrideGPUValidation = 1 flash option to mms.cfg like below: # mkdir /usr/local/etc/adobe # echo "OverrideGPUValidation = 1" >> /usr/local/etc/adobe/mms.cfg
would have an impact on any flash player fullscreen issues on FreeBSD and other BSD direvative OSes that run the linux-flash port.
