Share: About Scam

Scammers often pretend to be contacting you from or on behalf of the government e.g. Police Department, Anti-Corruption Agency, etc as well as a business you know e.g. a bank, or even a charity. They might use technology to change the phone number that appears. They might say: * you have committed crimes, you owe money or your family member has an emergency * there is a problem with your account and you need to verify some information * you won a prize or money but have to pay a fee to get it * your computer is infected Scammers want you to act fast before you have time to think. They might ask for your personal or financial information, threaten to arrest you, depot you, or sue you, your computer is about to die, or your account is hacked by someone, etc. DON'T GIVE YOUR PERSONAL OR FINANCIAL INFORMATION TO ANYONE. LEGITIMATE ORGANISATIONS WON'T CALL, EMAIL, OR SMS TO ASK FOR YOUR PERSONAL OR FINANCIAL INFORMATION LIKE YOUR PASSWORD OR CARD NUMBERS. If you need to contact a bu

How-To: Shop With Confidence

Online shopping is very common nowadays. Here are some tips you may find useful: 1. Shop on trusted sites / apps - e.g. shop on Shopee, eBay, Amazon, etc which are established. Both buyers and sellers are protected and it is easy for you to make a report in case of being scammed. Avoid buying from forum, Facebook, etc. An authentic online store or seller will have information such as who is the owner, who manage the online store, who is the service provider, contact information, retail store physical location, etc. Evaluate sellers. As long as you don't feel confident, don't buy. Too good to be true? Don't buy. 2. Buy from trusted sellers - Always visit seller's page / profile, browse thru the store, read the terms & conditions, policies e.g. return policy, etc. The most important thing is to check feedback from buyers. You wouldn't buy anything from a seller who looks new and unknown, no review, no selling record, etc, would you? 3. Shop on websites that have S

How-To: Make Certificates Using Microsoft PowerPoint

It is actually very easy to make certificates using Microsoft PowerPoint. There are plenty of templates you can choose and modify. 1.

How-To: Be More Secure Online

1. Use unique passwords for your accounts - e.g. emails, Facebook, etc. Lets say your Facebook account has been hacked, at least your email account is still safe because you are using different passwords for your email and Facebook accounts, and you are able to try to recover your Facebook account. Unique password also means difficult for people to guess, e.g. G89?klz01?8955hjk instead of password123, qwerty, etc. 2. Turn on Two-Factor Authentication (2FA) - this adds another layer of security to access to your  accounts. 2FA verifies your identity by another factor: something you own, something you are or something you know, e.g. using your mobile phone number - get a SMS with a special code to enter. By enabling 2FA, you will get a text message every time you or someones try to log into your account. 3. Enable passcodes - this adds another step when you are about to perform something, e.g. you will need to unlock your banking app by keying in your passcode before you can do or view t

Share: Morse Code

Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes or dits and dahs. Morse code is named after Samuel Morse, an inventor of the telegraph. International Morse Code, also known as Continental Morse Code, encodes the 26 English letters A to Z, some non-English letters, the Arabic numerals and a small set of punctuation and procedural signals (prosigns). There is no distinction between upper and lower case letters. Morse code can be transmitted in a number of ways: as electrical pulses along a telegraph wire, as an audio tone, a radio signal with short and long tones, or as a mechanical, audible, or visual signal e.g. a flashing light  or even a car horn. Some mine rescues have used pulling on a rope, a short pull for a dot and a long pull for a dash. Morse code is transmitted using just two states - on and off. Historians have called it the first digital code. Morse code may be rep

Share: Phonetic Alphabet

The phonetic alphabet is a list of 26 words, for each letter of the alphabet. Each word represents the letter that it begins with. The phonetic alphabet is often used to clear up any misunderstanding over the pronunciation of letters, e.g. a “M” for a “N” or a “B” for a “P”. In certain countries, there is no standard phonetic alphabet. Instead, contact centres often use names and cities to identify letters, e.g. A - Adam, B - Boy, C - China, etc. Notes: * First introduced by NATO in 1955. * The NATO (North Atlantic Treaty Organization) Phonetic Alphabet is currently officially denoted as the International Radiotelephony Spelling Alphabet (IRSA) or the ICAO (International Civil Aviation Organization) phonetic alphabet or ITU (International Telecommunication Union) phonetic alphabet. * The NATO Phonetic Alphabet is also known as telephone alphabet, radio alphabet, word-spelling alphabet, or voice procedure alphabet.
