ALL ABOUT ME
As you’ve probably noticed, I’m an IT geek. I have a BSc in Computer Science (IT). I’ve also completed a diploma in TEFL. Check-out my online CV here or download my latest creative CV here and my timeline here.
WHAT I LIKE WORKING ON
I’ve worked on a range of technologies, from Lotus Notes, Mainframe, Oracle to PHP (Web development). My vast exposure to different technologies has empowered me to adapt and evolve quickly. Currently I enjoy working on cloud and mobile application development.
I love teaching – its a new found passion for me since 2010. It’s an amazing profession and one of the most rewarding I’ve ever experienced. I’ve been teaching full-time/part-time since 2010 at Berlitz Al Ahsa. I’ve taught English to kids from ages 6 to an adult in his 60s – truly an amazing journey that has really defined my character.
DIY / PHOTOGRAPHY / CRAFTS
As a human, I like to question everything. I like to understand how things work, why they are how they are, and how it affects what I do. I love working with my hands and converting my crazy ideas into art. From wooden art, painting, and general DIY around the home/office I love to play. Still a very junior photographer with a Nikon 3100 I’ve recently been clicking galore.
Skills // Senior Business Analyst with a passion for technology. With over 15 years experience in IT, and 4 years instructional experience (ESL). I have a creative mind comfortable with working with graphics and web technologies and the ability to adapt and learn quickly are my strengths.

This is a nifty little device: a credit card with an onboard one-time password generator. The idea is that the user enters his PIN every time he makes an online purchase, and enters the one-time code on the screen into the webform. The article doesn’t say if the code is time-based or just sequence-based, but in either case the credit card company will be able to verify it remotely.
The idea is that this cuts down on card-not-present credit card fraud.
The efficacy of this countermeasure depends a lot on how much these new credit cards cost versus the amount of this type of fraud that happens, but in general it seems like a really good idea. Certainly better than that three-digit code printed on the back of cards these days.
The credit card generator generates credit card numbers in a random manner, which guarantees that the generation is valid, based on a numerical pattern and digit verification. These fake cards obtained by a credit card generator are not used to make any purchase, because although they are valid the numbers are fictitious, so they are used only by those people who need to generate a transaction, usually online and They should check to have a credit card, but do not count on it.
Valid generation of a credit card
A credit card is an instrument that is used as identification material for a credit user of a bank, this is usually made of plastic, has a magnetic stripe, has a microchip, and a number that identifies the card, which is marked in relief. Credit cards are issued by a bank or financial institution, which authorizes the cardholder to use it as a form of payment in businesses that are affiliated with the system, through their written or electronic signature, in addition to the display of the credit card. A credit card is a form of financing, so the owner assumes the obligation to pay the amount he or she had, in addition to the interest generated by its use, including bank fees and expenses previously agreed upon.
Why did my credit card payment fail?
We’re sorry to hear you’re having issues with your credit card payment.
To solve the issue, try:
using a credit card – we accept Visa, American Express, and Mastercard.
double-checking that you have entered your card information correctly – there should be no spaces between characters.
confirming with your bank that your credit card is valid for international purchases.
completing the purchase in a different browser.
using a different credit card.
In most cases, the payment fails because your credit card issuer has blocked it to protect you from fraud when an international purchase is made. To resolve this issue, you will need to contact your bank.

To merge Word documents, you can merge those documents within Microsoft Word itself. To do this, open the first file in Microsoft Word, and follow the steps for your version of Word. The steps are different because of the changes between the file menu and the Office ribbon.
In the Word ribbon, click the Insert tab, click the down arrow next to Object, and select the Text from File option, as shown below.
Select the file you want to merge into the current document and click Insert. Once completed, the text and other information from the document will be merged into the current document. These steps can be completed as many times as you want if you want to merge multiple files.
Tip: If there are multiple files you want to merge at the same time, you can select multiple files by holding down the Ctrl key and selecting each file you want to merge.
Microsoft Word 2003 or earlier (file menu)
In Word, click on Tools in the top menu and select the Compare and Merge Documents option, as shown below.
Find the document you want to merge. You have the option of merging the selected document into the currently open document or merging the two documents into a new document. To choose the merge option, click the arrow next to the Merge button and select the desired merge option. The files will then be merged.
Tip: If there are multiple files you want to merge at once, you can select multiple files by holding down the Ctrl key and selecting each file you want to merge.
Merging Microsoft Excel files
To merge Microsoft Excel files together, it is best to save them as CSV files first. Open the Excel files and in the menu bar, click File, then Save As. In the Save as type drop-down list, select CSV (comma delimited) (*.csv) from the list.
Type in the following command to merge all CSV files in the folder into a new CSV file titled “newfile.csv” (any name could be used).
copy *.csv newfile.csv
After the new file has been created, open the new CSV file in Microsoft Excel and save it as an Excel file.
Merge a text (.txt) file in the Windows command line
Place each of the text files you want to merge in the same folder. For ease, place them in a folder in the root of the C: drive (e.g., c:\textfiles) and make sure the folder only contains text files you want to merge.
Tip: Before merging text files, you may want to make sure there is a blank line or at least one carriage return (pressing the Enter key) to help separate each file.
PDF documents can also be merged. You can use a full version of Adobe Acrobat to do this, but this program is a bit pricy (several hundred dollars).
Another option is to find a free utility on the Internet to merge your PDF files. One of the better free utilities is PDF Split and Merge. It is an online tool that lets you merge two or more PDF files into one PDF file with a few clicks of your mouse button. You can also download and install a version of the Batch PDF Merger program, which costs about $30.
There are other free utilities online that offer this service. However, if there is any confidential information contained in the PDF files, use caution when merging them online. It is recommended that you use a utility on your computer for these types of PDF file mergers, to ensure the confidential data is kept confidential.
MergePDF – Online utility to merge PDF files up to 30 MB.
PDFMerge – Another great free utility to merge PDF documents.
Sej-da – An additional utility to merge PDF files up to 50 MB.
Oh, occasionally you’ll be asked to go detective and solve a mystery:
“A windowless room has three light bulbs. You are outside the room with three switches, each controlling one of the light bulbs. If you can only enter the room one time, how can you determine which switch controls which light bulb?” (source)
Too easy? Here’s another:
“Four investment bankers need to cross a bridge at night to get to a meeting. They have only one flashlight and 17 minutes to get there. The bridge must be crossed with the flashlight and can only support two bankers at a time. The Analyst can cross in one minute, the Associate can cross in two minutes, the VP can cross in five minutes, and the MD takes 10 minutes to cross. How can they all make it to the meeting in time?” (source)
7. The “How Would You Do Something Ridiculous” Question
And this last category is all about putting your creativity (and I guess, sometimes violence?) to the test:
