Practical Use of Open Source Code Software
Practical Use of Open Source Code Software By: Roberto Sedycias As we started the project of our web site, we knew that the proprietary software costs would be too high for our financial resources. Our only option then was to make use of Open Source Code softwares. However, within the Open Source Code there are lots of softwares to choose from, and it´s up to the system analyst/programmer to pick the ones that best suit the project goals. In our case, we picked Linux as our operating system. However we faced a big question: Which Linux distribution ? There are dozens of linux distributions, each one with specific advantages, sometimes with or without paid services. We chose linux Slackware because we thought that it would suit better our needs, in terms of stability and reliability. Slackware is a conservative distribution, meaning that it only offers in its distribution package kernel versions and third party libraries, once it´s been proved to be stable and reliable. As a result, Slackware is one the most stable Linux operating system on the market. If the user wishes the most recent Linux kernel and libraries, we recommend to look for a different distribution. Another reason for us picking Slackware, was because of its text interface, which at the beginning may become a bit difficult, in the long run however it offers a better understanding of the Linux environment. This way most of Slackware configurations are done thru text scripts. Once it was set the operating system, we picked Apache as our web server. Apache is one of the most popular web server in the internet. For server programming language, we chose PHP. Also, a very popular programming language. Our experience with Apache/PHP proves that this setup is very reliable, working extremely well in our production environment. For workstation programming language, we chose javascript, which besides of having a simple syntax, it offers lots of resources. Apache web server is really a complete web server. Also, it can become very complex with many configuration setups. For our database, we picked Postgresql. This database has been made available to the public for more than 15 years, and besides of being well debugged, it offers so many resources that it has become one of the best database options from Open Source Code softwares. Extremely reliable, Postgresql has reported cases where there have been databases in production with over 4 terabytes. Besides all of that, Postresql is not the most popular Open Source Code database. A matter of marketing ? Probably. As for the programming language PHP, we had to use an object oriented application structure. There are many PHP application structures being offered with Open Source Code license. Object oriented application is very important, because it makes programming very easy and scalable up to the point where the system may grow without many problems. Also, it helps to keep PHP code separated from HTML, with the help of some specific libraries, such as Smarty. We make use of Smarty library and we believe that it is a very important resource, which can even make web pages faster thru the use of its cache functions. Also a very important set of libraries worth mentioning for PHP systems, is the PEAR libraries. In PEAR web site, among the many libraries being offered, there are the database interface DB and the MAIL_QUEUE, which sends emails thru the use of database. As we came to the end of our project, we had to use some sort of real time database replication. For that we chose the DRBD and Heartbeat libraries. The use of database replication is very important and should not be postponed. Just after 3 months our system got into production, our server hard disk became bad. Thru the use of DRBD/Heartbeat we were able to put the system back into production within seconds, without loosing any data. DRBD/Heartbeat replication is done thru the use of a lan network between the server and slave nodes. Our project also makes use of ImageMagick (enlarge and reduce images), Iptables (firewall), Tsearch2(text search in portgresql) and Mon (linux monitoring tasks). Also a very important library worth mentioning is the pseudo APC compiler for PHP. Speed is always a critical factor for internet sites. Our web site is already in production and based upon our experience we can say that the Open Source Code softwares we picked, proved to be extremely reliable and stable. Open Source Code softwares can certainly be an excellent option for developing web sites.

Doors of the Mind
How does the Mind work?
Psychologists explain very beautifully and sometimes almost convincingly this bya concept of Doors of the Mind .Thry postulate that the bunch of keys to all these doors are entrusted to us at the time of our birth.This may be quite comforting to the human ego but is rather unconvincing
As we grow up we make voluntary choices about which doors to open and which not. However, it appears that the Mind is conditioned as we grow up The psychologists,however, admit almost in passing the restrictive role of genetics as also familial upbringing in conditioning our options. However, they do not refer to the inalienable character of such impressions. Actually by the time we grow up these influences form a part and parcel of our individuality and dictate our choice of keys, The complexes about untouchability, religion etc form a part and parcel of our makeup.
Not that such influences are always negative. What is significant is that they restrict our choice of keys. Like the marionette we are unaware of these invisible strings which modulate our movements. The Bible says there are many Mansions of Philosophy in the House of My Lord. But a non-believer restricts himself to the dark and dingy rooms. The overtly religious tone of the reference is unintended. Such adverse influences can be so negative that we consider the very idea of unlocking some door/s is blasphemy .Religious bigotry is a prime example of this. Could this inchoate complex be the birthplace of the ani-Christ?
While such ‘inborn’ impressions severelly restrict our choice of the keys some ongoing influences also tend to delimit it.The blasts by the terrorists all over India are instances in point.The general reaction to them is so hackneyed that it reveals the deep-rooted malaise within us. Despite strong evidence about the perpetrators of such blasts at Nanded, Malegaon and Kanpur we firmly keep the doors locked even throwing away the keys lest we are tempted to peep in,just in case. A free-lance writer from Delhi even received threats to his life for he expressed his doubts in the matter.
The biblical idea of Free Will does appear quite tempting and the Psychologist’s making us Keeper of the Keys is quite soothing indeed.But ,as it appears,we are only Keepers of the Keys subject to strict restrictions on their use.The unfortunate fact is that we have the capacity and power to access any and every door but are victims of a self-imposed paralysis.How does the Mind work?
