Removing www from your URL

I finally decided to shut down my home based server for HTTP use for good. Why? With all the school work, I don’t have time to fix issues with the system. It comes with an added benefit of having a site that will be up 99.99%(according to the hosting provider’s uptime guarantee.) unless I make a coding error.

Anyway, while I was transferring data from self hosted server to the new hosting provider, I ran into few issues. One would be the transfer of data from the wordpress self host system to the paid professional service. I am still working on database issues such as my massive collection of multiple choice questions database for University of Calgary courses. Continue reading Removing www from your URL

Website migration and future of the site

Last week was super busy because I got the flu on top of exams and papers as usual. Each year around February to March I get the seasonal flu. I also had to write the Geochemistry midterm II, which is crucial for my success in the geology program. In the midst of my anxiety over the exams and the upcoming draft paper on the analysis paper for the Science 311, I decided to migrate all my data, exception to the Science site, from general PHP database with no CMS (Content Management System) to completely WordPress(WP) based system. I didn’t have to do much other than copying and pasting the data from old files since WP module has been installed and running on my server for the last few months. The old pages are still slowly being phased out. I will keep the old pages until Google decided to take them down from their indexed pages. With this migration, as the site admin my work load has been cut down significantly. The process of adding new information, pages, data, media, modifying existing data, layout, etc is much easier and faster with WP CMS. Since I am still working my degree, I may not update the site often, but I will do my best to come up with new information for the readers. Continue reading Website migration and future of the site

PHP based password protected access point

I found a PHP based script that will protect data from the general public. This is done using a simple PHP script that will terminate the page data from processing in HTTP request if a correct credential is not entered. The key part of this script is that it can be saved in any folder on the server regardless of the folder access is public or private. The script can be used to protect any web page using the PHP’s native data loading mechanism. I have no idea how secure the PHP script now protecting the secure science area. That’s where detailed user records comes in handy because in an event of a hack or a flooding, I can monitor the situation and close down all lose ends of the system.

Science section of the main site was updated

Today I add my geology lab final exam cheat sheet information in the Science section of the main site. Feel free to read it at the Science site. It takes time to update all the area of the website, but I do my best to keep up with it.

Anyway, let’s talk about some interesting things I learned in Mineralogy class…

Did you know that there are minerals that you cannot have together no matter what? For example, it is impossible to have Olivine with Quart together because they are formed in two different opposite conditions, where it is scientifically impossible to form both minerals at same temperature and pressure.

RAID explained…

I did write about my sever structure with a bit of explanation on Redundant Array of Independent Disks (RAID) before. But today I came across an email I sent out to one of my friends explaining how RAID works and what each type of RAID benefit each situation. Today I will post the email as it is and after the final exams, I will rewrite this article to include more specific details.

RAID(redundant array of independent disks) protection technology is developed to safe guard data in an event of a hardware failure. I found that it is easy to use online info than to type all the explanations. You can read about RAID and watch the following movies to learn the technical information:
