Mcdodo 2-in-1 USB type-c and micro USB fast charging data cable

If you bought a latest smartphone that uses USB type-c connector instead of the old style micro USB, you might probably want to search for some 3rd party fast charging and data sync cable for it.

If you still possess other smart mobile devices that use micro USB, a 2-in-1 cable that supports both USB type-c and micro USB will be very nice. If you also have Apple iPhone, perhaps a 3-in-1 cable that supports USB type-c, micro USB and lightning will be even better.

For this reason, I have recently bought some Mcdodo brand 2-in-1 USB cables. They have another 3-in-1 model as well with the Apple lightning connector.


This cable is 1 meter long, and supports fast charging with 2.1A current output. One end of it is normal USB connector, and the other end of it is a micro USB connector. What makes it special is it also comes together with an adapter that tied with it, which can be connected to its micro USB connector to convert it for USB type-c connection.


It also comes with a handy silicon belt that can be used to tie the cable up nicely in an organized manner for easy carriage.

Its cable is insulated with thermoplastic elastomer (TPE) material, which is robust, durable, anti-abrasion, anti-pull, anti-wrap and has high resistance to heat, oil, direct sunlight, flame, water, acid, alkali, alcohol, etc.

Top 10 database security threats

Databases are among the most valuable assets in the information system as they store valuable and vital data and records of the business. As such, they are also among the most interested place of intrusion for hackers, attempting to gain access to confidential and sensitive information from within.

California based cyber security solution provider Imperva has been consistently publishing the Top 10 Database Security Threats white paper every year.

From year 2013 until 2015, this top 10 database security threats remained as the same listing, with the same ranking, as below:

  • 1. Excessive and Unused Privileges
  • 2. Privilege Abuse
  • 3. Input Injection (SQL Injection)
  • 4. Malware
  • 5. Weak Audit Trail
  • 6. Storage Media Exposure
  • 7. Exploitation of Vulnerabilities and Misconfigured Databases
  • 8. Unmanaged Sensitive Data
  • 9. Denial of Service (DoS)
  • 10. Limited Security Expertise and Education
According to Imperva, the top 9 threats above can be addressed by using an automated Database Auditing and Protection (DAP) platform, which is an approach that improves security, simplifies compliance, and increases operational efficiency. The 10th threat is "human factor" by negligent employee or contractor.

The white paper outlined a multi-layered database security defence strategy encompassing:
  • Discovery and Assessment: to locate where database vulnerabilities and critical data reside.
  • User Rights Management: to identify excessive rights over sensitive data.
  • Monitoring and Blocking: to protect databases from attacks, unauthorized access, and theft of data.
  • Auditing: helps to demonstrate compliance with industry regulations.
  • Data Protection: to ensure data integrity and confidentiality.
  • Non-Technical Security: to instil and reinforce a culture of security awareness and preparedness.
"Failing to safeguard databases that store sensitive data can cripple your operations, result inregulatory violations, and destroy your brand. Understanding the top database threats and implementing the solutions outlined in this paper will enable you to recognize when you’re vulnerable or being attacked, maintain security best practices, and ensure that your most valuable assets are protected." -- Imperva, 2015

Pisen TS-D192 4-in-1 presentation laser pointer pen and power bank (2nd generation)

If you do a lot of public presentation or classroom lecturing, you will find a presentation laser pointer pen as a very useful gadget for you to remotely control the flow of your presentation which run from your laptop and projected on a screen, as well as using its laser pointer to draw the audients' focus onto a particular area in your presentation screen.

I am using the Pisen TS-D192 4-in-1 presentation laser pointer pen and power bank for that purpose. In fact, it is more than just a presenter pen, it is also a 2,500 mAh power bank. It cost around RM70.


The Pisen TS-D192 has 3 buttons and can serve 4 features:
  • Laser pointer
  • Presentation remote controller
  • Video remote controller
  • Power bank


When you press its middle button, it will shoot up a red laser beam, with a long shooting range of up to 100 meters.

This Pisen TS-D192 comes with a nano USB receiver, which you can plug into your computer's USB port. It is really plug-and-play and can function immediately in Windows XP and above, even without the need of installing driver.

Its wireless transmission is using 2.4 GHz frequency band, with effective transmission range of about 10 meters. Unlike those infrared presenters that you need to aim the pen to the receiver, this Pisen TS-D192 which use 2.4 GHz wireless technology can work well regardless of its angle and direction, as long as it is within the 10 meters transmission range.

When your computer is running PowerPoint or Adobe PDF Reader, its buttons function like this:
  • Press top button to Page Up (go to previous slide)
  • Press bottom button to Page Down (go to next slide)
  • Long press top button will toggle full screen presentation
  • Long press bottom button will toggle a black screen on the display
  • The middle button will trigger its laser beam
When your computer is running Windows Movie Player or VLC Media Player, its buttons function like this:
  • Double press middle button to toggle between Play and Pause
  • Press top button for Forward
  • Press bottom button for Reverse

Most of the presenter pens in the market are powered by either AA or AAA size normal battery. This Pisen TS-D192 is powered by an internal rechargeable 18650 Li-ion battery with capacity of 2,500 mAh.

It can be recharged using a normal USB charging cable connecting its micro USB charging port to either your computer or a USB charger. There is a USB charging cable included in its packaging.

It is said that you can use it as a presenter pen for about one year with just a single charge. With its abundant power, it can also serve as your emergency power bank with 5V 1A output to charge up your phone or gadgets.


This is an interesting USP for the product, as you can still making use of it as a power bank when you are not using it for presentation.

Docasa DCS-BS02W non-electric water bidet for toilet water closet

I have just installed some Docasa DCS-BS02W non-electric water bidets in my residence's toilets. Each set of them cost only RM175 (or RM185.50 after GST).


This type of water bidet spray is pretty simple in design, and does not need to use electric to function. Just affix it onto the toilet bowl and attach its pipe to the existing water inlet of the water tank, and it is ready to function.


Its nozzle is able to spray water at the pressure of 0.05 MPa to 0.8 MPa, and its spraying angle is adjustable.


This Docasa DCS-BS02W is very easy to use. It has a level to adjust the high/low angle of water spray, and a big knob which clockwise is to spray the water at different intensity, and anticlockwise is a self-cleaning function whereby water is flowing down instead of spraying out.


This kind of water bidet is very popular in Japan, Taiwan and some other places. Normally they are electrical which can heat up and supply warm water, and the price is quite expensive. Although this Docasa DCS-BS02W is not able to heat up water, it is non-electric and very easy to install, and its price is much more affordable.

If you are still using toilet papers or external spraying hose, you might probably also want to switch to this type of bidet. It is gentle, clean and environmental friendly. I also makes your toilet looks modern and classy to your guests.

The Johari Window

The Johari Window is a model developed back in 1955 by 2 psychologists Joseph Luft (Joe) and Harrington Ingham  (Harry), named after their combined first names.

It is a heuristic method originally used for self awareness, to examine your characters that you are aware of, and those that others are aware of. There is also a portion which so far nobody is aware of.

The Johari Window consists of 4 quadrants:

  • Open / Arena: represents traits of subject that both you and others are conciously aware of.
  • Hidden / Façade: represents traits of subject that you are aware of, but hidden from others.
  • Blindspot: represents your blindspot where others are aware of but not you.
  • Unknown: represents the mysterious area where nobody is aware of yet.
Nowadays the Johari Window is also commonly used in knowledge management, to examine the areas of knowledge between 2 parties (eg. superior and subordinate, supplier and customer, 2 different departments, 2 colleagues, 2 business partners, ...)

There are parts that known to both parties, and also parts that known to one party only, and also parts that unknown by both parties.

By sharing of information/knowledge with each other, i.e. ask for the parts in your blindspot, and tell about the parts in your hidden area, the open area can then be expanded.
At the same time, both parties will explore into the unknown area. The discovered parts will then be included into own hidden area, and if shared out, will further enlarge the open area. The parts discovered by the other party will initially fall into your bind area, and if shared out, will also become part of the open area.

Think of a person or a group in your mind, what is the Johari Window looks like? How you would like the Johari Window to look like? What action should you take to make that happen?

UniFi goodies: Switch to HyppTV Ruby Pack at no additional cost and get RM30 AEON Shopping Voucher

Today, I've received an email from TM Takeout with their HyppTV Mooncake Festival Ruby Pack Migration Campaign 2016 promotion as follow:


I have carefully checked the sender's email. It is not a scam and is really sent out from TM email server.

I clicked on the link and checked the URL of the webpage opened by the link. It is an HTTPS secured webpage, with valid SSL certificate issued by Entrust CA.


So, it is real!

I then checked on the Terms and Conditions that I need to agree in order to accept the offer.

The Terms and Conditions states that:
  • The Campaign starts from 1 September 2016 until 15 September 2016.
  • Only eligible to existing HyppTV subscribers of Aneka or Varnam Pack.
  • The migration to Ruby Pack is free of charge, and there will be no additional monthly charge as long as the migration was done within this campaign period.
  • Subscribers who have done the migration within this campaign period are eligible to receive a HyppTV Moon Cake Festival AEON shopping voucher worth RM30.

Its too good to be true as there is nothing to lose for the subscriber to accept the migration offer, and at the same time can get a RM30 voucher too.

Normally, the Ruby pack is RM10/month more expensive than the Aneka and Varnam pack for TM UniFi subscribers.

The Ruby pack consists of Chinese channels including tvN HD, Channel [V] Taiwan, now Baugu Movies, now Chinese Drama, now Jelli HD, Red by HBO, SCM, SCM Legend HD, SETI, Star Chinese Channel and TVB8.



So, if you also received this offer email from TM Takeout, think carefully first before trash it away. If you haven't received it, you might probably want to find it in your spam folder, or call 100 to find out from TM about your eligibility.

MEGA cloud storage with 50GB free quota and secured RSA-2048 encryption

Nowadays there are at least twenty over cloud storage service providers. Some of them provides free quota usage, such as the famous Dropbox (2GB), Google Drive (15GB), Microsoft OneDrive (15GB), pCloud (10GB), etc. while some other don't.

If you are looking for large amount of free storage, probably to store your precious videas, photos, disc images, etc., you should take a look at MEGA which generously provides 50GB free quota.


MEGA was founded in New Zealand by Kim DotCom in 2013, who was also the founder of the famous file-hosting website Megaupload. Megaupload was shut down by US government after being accused for copyright infringement. Anyhow, MEGA says Kim DotCom has already resigned as director since August 2013.

MEGA has on 23 August 2016 announced that they've reached a milestone of 50 million registered users with more than 20 billion files stored in their cloud service.

There is an article in Cloudwards posted in 18 September 2015 comparing MEGA with Google Drive, OneDrive, Dropbox, SugarSync and SpiderOak, and concluded with the following comparison table:

(Comparison table from Cloudwards website)

MEGA can be accessed with any one of the following medium:
  • MEGA Sync client for Windows, Mac or Linux
  • MEGA mobile app for Android, iOS, Windows Phone or Blackberry
  • MEGA web browser extension for Chrome or Firefox
Its usage experience is similar to Dropbox, Google Drive, OneDrive, etc. Its upload/download speed for free users is OK, I can get about 2 Mbps speed as shown below.


With its generous 50GB storage for free users, I find MEGA pretty attractive as a cloud storage for my videos, photos, disc images and other big files.

Note that users of Microsoft Office 365 are getting 1024GB bundled quota in OneDrive, which is much more larger than this 50GB. So, if you are genuine user of MS Office 365, you can make good use of your bundled 1TB space in OneDrive too.

HTC flagship smartphone users can also claim for 2 years usage of 100GB free additional storage in Google Drive through the pre-installed Google Drive app in the new phone. Beware that after 2 years, this 100GB additional storage quota will be revoked, unless you buy another new HTC flagship smartphone, and provided this offer is still available by then.



BC-01 multimedia bluetooth speaker with alarm clock and FM radio

I have purchased a BC-01 multimedia bluetooth speaker with alarm clock and FM radio for my kid. This made-in-China gadget is pretty cheap, with the price of around RM60 only, and its quality is not too bad.


The BC-01 has 2 colour options: white and black. It is pretty small, with surface about the size of the palm of an adult. This small footprint, together with its built-in 1,500 mAh Li-ion rechargeable battery, makes it very portable and easy to carry long, especially when travelling.

With a low power consumption of around 3W, the battery is good enough to support for many hours of continuous music playback. It can operate in clock display and alarm mode for a few days at a single charge cycle.


It has a pair of stereo speakers, which is pretty decent with sufficient loudness in volume. Do not unfairly compete it with Hi-Fi speakers, but its sound quality can really beat the speakers of most of the smartphones and tablets nowadays. However, probably due to the use of internal antenna, you'll probably be disturbed with some hissing sound when using it as a radio.

So, what can this small gadget do?

First of all, it is an alarm clock with pretty large LED time display, as you can see from its photo above.

Then, it is a Bluetooth wireless speaker for any multimedia devices that support Bluetooth pairing. It also has a built-in microphone and can act as Bluetooth hands free speaker for mobile phone, able to pick up calls and have phone conversation with it.

The phone recognizes it for phone audio (to handle phone calls) as well as media audio (to play music streaming from the phone).


It also has a micro SD slot that supports micro SD up to 32GB. You can store music files of MP3, WAV, APE or WMA format in a micro SD card, slot in the card into its slot, and use it as a music player.

It comes with a special USB cable with 2 split connectors. One of it is the USB connector used as external power source and for battery charging, another is an audio jack which you can plug into another music device, computer, handphone, etc. and use it as an external speaker for such device.

Lastly, it is also an FM radio with internal antenna. It is able to automatically search for radio stations and remember their frequency.

Despite its multiple functions and features, it only has 6 control buttons, as shown in its photo above. Therefore, it takes some time to figure out how to use it. It comes with a paper User Manual and I highly recommend you to RTFM before you start using it.

One thing I dislike about this device is that, it only uses a single button to sequentially rotate and switch among its functions as Bluetooth speaker, micro SD card multimedia player, FM radio, AUX line-in speaker, and alarm clock. So you need to keep on pressing its right button until you reach your desired function.

All in all, this is a pretty cool device for bedroom radio and alarm. It is a good candidate as Christmas or birthday present too.

GuardKey - your sensitive data protection solution for local storage, portable storage and also cloud storage (ie. Dropbox, Google Drive, OneDrive, etc.)

"A lot of people use Dropbox.

A lot of people put a lot of valuable, sensitive and personal data inside Dropbox.

A lot of people make the mistake of not encrypting their valuable, sensitive and personal data before they put it inside Dropbox.

Which all adds up to a whole heap of trouble if Dropbox suffers a data breach."

-- Quoted from Graham Cluley's article titled "The huge Dropbox password leak that wasn't".

Yes, your data in cloud storage such as Dropbox needs a second layer of protection despite being well encrypted and taken care by Dropbox.

This is because most of the time, the data in your cloud storage can be easily accessed once your password is obtained or hacked.

Worse still, most cloud services such as Dropbox provides the convenience for you to stay logon once you successfully signed in from their apps, be it from a computer or mobile device. This means that whoever obtained physical access to your computer or mobile device with an active logon session to your cloud service, can easily access to your data without even the need to know your password!

Nowadays, most cloud services like Dropbox do provide option for additional security through 2-step verification which requires second verification through SMS, USB key, etc. beside your password. However, novice users find it difficult to configure and activate, and there is limitation in the USB key method, such as, can only be used when accessing the cloud service with Google Chrome browser. In addition, this 2-step verification doesn't solve the open session loophole as described in the above paragraph.

I found a wonderful product called GuardKey which perfectly fills this gap of needs by offering data encryption and concealing solution to not only your cloud storages, but also your local storage (eg. harddisk, NAS storage, SAN storage, etc.) and portable storage (eg. USB drive, SD card, etc.).


GuardKey is a USB dongle with the following components:
  • A unique AES-256 encryption/decryption key.
  • A Windows software to be installed in your computer to perform seamless data encryption and decryption to your Safebox (an invisible folder in your storage device that everything in it will be protected by GuardKey).
  • 8 GB of free empty storage, for you to use the USB dongle as normal USB drive.
This metallic USB key has a solid and durable look and feel.

There is always a trade-off between security and convenience. The higher the security measure, the more inconvenience for the user it become, and vice-versa. The beauty of GuardKey is it provides a wide range of flexibility level to the user to determine between high security and high convenience.

If user opts for high security, the Safebox can only be opened with the USB dongle and a password. In a more convenient level, it only needs the USB dongle without the need of entering password. Plug in your GuardKey dongle, you have access to your Safebox; pull out your GuardKey dongle, your Safebox will be hidden, and even if found, all the data inside it is encrypted with AES-256 (Advanced Encryption Standard with 256 bits cryptographic key length) encryption, which is a military grade encryption method that recommended by NSA for US government to protect Top Secret grade of information.

Alternatively, you can also make it possible to unlock the Safebox without using the USB dongle, by using the GuardKey Viewer mobile app. The mobile device running GuardKey Viewer needs to be paired with the GuardKey application running in the computer before it can be used as Safebox mobile unlocker.

There are 2 levels of mobile unlock security: by using a six digit one-time-password (OTP) which changes every minute, or by using a combination of random sequence of images together with the six digit OTP.



GuardKey supports the creation and usage of Safebox in local disk (including portable storage) and also in Cloud storage.


Supported cloud storages including Dropbox, Google Drive, OneDrive, ASUS WebStorage, Box, SugarSync, and other cloud storages that sync with local disk, which the user needs to inform GuardKey about the location of the sync folder.


GuardKey supports one Safebox for each of the storage drive. The screenshot below shows I've created one Safebox for local drive D, and another for Dropbox.


The data inside these Safeboxes are encrypted and not accessible until they are unlocked by GuardKey. A virtual drive will be mounted with the Safeboxes now accessible as folders in the mounted drive. Once they are relocked, they will disappear from the virtual drive, and if all the Safeboxes are relocked, the GuardKey virtual drive will also be unmounted and disappear.


By using GuardKey, you can therefore ensure that all your AES-256 protected data in Safebox will remain be unreadable and inaccessible, even though your computer is stolen, seized or hacked. By encrypting your files and folders in cloud storage with GuardKey, you can also protect them from leaking and exposing through hacking or unauthorized access to your cloud storage account.

The same GuardKey USB dongle can be used in multiple computers to access the encrypted data in your cloud storage from different computer, so that you can access to your files from any one of the computers installed with GuardKey by using your dongle. In addition, you can also access your Safeboxes in cloud storages from within your smartphone by using the GuardKey Viewer mobile app.

GuardKey is a well thought product. In case you lost your USB dongle and you have not enabled mobile unlock option, you are still able to unlock your Safebox and rescue the data inside by using the backup AES-256 key residing in your local disk, which requires your password for its usage.

If you are concerned about this "backdoor" measure for emergency data retrieval, you can store your AES-256 key in another USB disk and lock it in a secured physical safe, then delete and wipe out the backup key in your local disk residing in data folder of GuardKey installed path.

Although the metallic GuardKey dongle is solid and looks durable, you might have the question of what if it is faulty and no longer usable. Without the key, how are you going to access to your valuable data protected by GuardKey? This situation has also been thought about, and there is a mechanism within the GuardKey software to allow you to duplicate the dongle to another USB disk.

As a conclusion, GuardKey is found to be very flexible between security and convenience, which you can adjust according to your need. In high security mode, I believe it is fit for commercial and industrial use. While in high convenience mode such as unlocking on the fly with USB dongle without the need of password, it can still protect your data, provided that your USB dongle does not fall into the hand of other people who at the same time also has your computer with them.

OCBC 360 Savings Account with up to 4.1% interest rate

I have opened an OCBC 360 savings account, which is statement based and without passbook.
ATM card can be applied at the cost of RM8 one time payment for convenience of account transaction using ATM machine.

This account has a fixed interest rate of 0.5% per annum. On top of that, there are 3 categories of additional interest of 1.2% per annum each to be earned for deposit amount up to RM100k.

The 3 categories are:

  • Deposit: to deposit a minimum of RM500 into the OCBC 360 account within the month.
  • Bill Payment: to perform at least 3 bill payments from OCBC 360 account using Internet banking or mobile banking within the month. This includes payment to OCBC credit card, payment to OCBC housing loan, and payment to any of the participating billing organizations available in OCBC Internet banking or mobile banking service.
  • Credit Card: to link an OCBC credit card to this 360 account, and to charge at least RM500 aggregated retail transactions to the credit card within the month. The calculated amount is excluding credit card fees and charges, balance transfer, instalment plan, cancelled transactions, etc.
Therefore, the maximum possible interest rate is 0.5% + (1.2% x 3) = 4.1%, for the first RM100k of deposit. The interest rate for additional amount above RM100k remains as 0.5% only.

This interest structure is pretty attractive and comparable to fixed deposit accounts.

OCBC 360 is an adult savings account for individual above 18 years old, and its 4.1% possible interest rate is even higher than most junior and/or teens savings account, which in turn higher than most normal savings account.

This account is insured with the Malaysian Deposit Insurance Corporation (PIDM) for deposit amount up to RM250k.

Apparently, this is a tactic for OCBC to attract working people to centralize their banking with them, which include monthly salary deposit, monthly bill payments, and credit card spending.

OCBC has been famous to give attractive offer with innovative products, such as their previous famous Titanium credit card. However, they also have the track record of making such attractive offer unattractive after a few years.

This OCBC 360 savings account was introduced somewhere in December 2015, which is considered still new. I think this attractive offer will stay around for quite some times, and if OCBC plays the trick to make it unattractive again, we can always pull out and deposit our money at other more attractive bank account.

The hacking of Telegram app and the vulnerability of relying on SMS as authentication method

Yesterday (2 August 2016) there was news about 15 million Iranian Telegram users mobile phone number exposed and more than dozen accounts compromised by hackers.

A chain is only as strong as its weakest link. This incident exposed that SMS, which is currently commonly used as authentication method in many online services including online banking systems, is vulnerable to security breach and could be the weakest link in the security measure.

Coincidently, Focus Malaysia Issue 191 dated 29 July 2016 has also just discussed about this vulnerability in its featured article titled "Overcoming The Two-Factor Vulnerability: When it comes to securing your web accounts, two-factor authentication using SMS is safer than just a standard password. But recent cases have shown that it might be time to move away from that."

Why is it not a good idea for online service providers to make use of SMS as security measure?

Firstly, the sending and receiving of SMS is depending on the telco service, which is totally out of control of the online service providers. Therefore, it is vulnerable to listening, hijacking, impersonating, replicating, and other kinds of security breaches along its sending and receiving process.

Secondly, technically speaking, personnel working in the telco can also easily manipulate the SMS as the control is with them. This is very likely the case as happened to Telegram users in Iran.

Thirdly, as mentioned in the article in Focus Malaysia, the code sent by SMS can be obtained using social engineering.

Fourthly, as SMS is sent to the phone, in the event the user lost his/her phone with the mobile apps of online banking, online stockbroking, etc., if the mobile apps are using SMS for authentication, whoever who got the phone can easily take control of the user's accounts, unless the SIM card in the phone is immediately barred, which then disables its SMS function.

As for the case of Telegram app, you can further secure your Telegram account by activating two-step verification, which will require your password to login beside your mobile phone number.

To activate two-step verification in Telegram app, go to Menu > Settings > Privacy and Security > Two-Step Verification and set your recovery email there. Your email can then be your last resort to safeguard your account from hijacking.

LED light bulb that fit in PLC downlight fixture

I have been wondering for a long time if the PLC downlights in my house that use CFL (compact fluorescence) bulbs can be replaced with LED light bulb without much modification. Today, I've finally found the answer.

One of my PLC downlights is faulty and I need to replace its 18W CFL bulb. While searching for its replacement at the shop, I found this...


Yes, it is the PLC light bulb with 2-pin leg that fit with the fixture of my downlight. Instead of CFL tubes, this product is using LED as its lighting source.

So, this is exactly the LED solution that I've been searching for years. Even better, this kind of LED light bulb fit exactly to the existing PLC fixture, and totally no modification is needed.

This LED light bulb is more environmental friendly than the CFL, as it contains no mercury. It also claims to have longer lifespan than CFL, and consume less electricity to obtain the same amount of lumen output. In addition, LED light generates much less heat than CFL. It is also said that LED light does not attract insects, which is a desirable feature. However, this LED bulb is a little bit more expensive than its CFL counterparts.

I have purchased one to replace the faulty CFL bulb. See it in action below:


Finally, I've found the solution to change my PLC based downlights at my house to LED type.

I have been gradually changing the CFL bulbs with E27 base to LED type, as LED light with E27 base has been around for a few years.

Eventually, most if not all the lamps at my house will be LED based, when the CFLs are gradually replaced after they have reached their end of life.

Changed my car battery with The Battery Shop

I've just changed my car battery today with the service from The Battery Shop.

My old battery was still able to crank up the car engine, after serving for about 2 years. I decided to make an appointment with The Battery Shop for a free onsite checking, after experienced 2 times of car clock reset itself to 12:00 and 1 time of all the radio station preset memory gone. Yesterday, the VST-706 voltmeter in my car has shown unstable voltage that kept on changing within the range of 13.0V to 14.8V when the car is running.

2 young men arrived at my home right on time of the appointment. They called me about 40 minutes earlier to conform the appointment before they came.

They checked my car electrical system and informed me the car alternator is working fine. They found greenish residue developed at the anode terminal of the old battery. Decision was then made to replace the old battery with a new Korean brand Atlas BX 75D23L sealed maintenance free (SMF) battery.

They kept my car engine running during the changing of battery. The whole process was less than 5 minutes. All the settings and memory of the car's clock and radio system are still remained after the battery swap.

Here is my car's new battery, up and running at its place. The voltage supplied is now stable at around 14.2V when engine is running with this new battery.


The Battery Shop's onsite service (delivery, inspection and installation) at Klang Valley area is free of charge. The 2 young technicians I met were polite and the job was professionally done. I was given a RM20 discount, and the new battery cost me RM310. This price is quite reasonable, as 75D23L battery is of higher spec than 55D23L and therefore carries a higher price tag.

The new battery comes with 12 months warranty with warranty card and a car sticker. The technicians informed me that if they see this sticker on my car's windscreen during their next service, they will provide RM20 discount for the next battery change.


I am aware that The Battery Shop is in direct competition with BateriKu. The brands that they carry are different, and the team is also different. If you prefer Atlas BX or GP, you can contact The Battery Shop; if you prefer Century, Yuasa or Astra, you can contact BateriKu.

Wireless-AD - the next generation WiFi (WiGig) with Gigabit per second speed

Perhaps many of you have just upgraded your WiFi network from Wireless-N to Wireless-AC just like me, the next generation of wireless network namely IEEE 802.11ad has already come to the market.

Instead of operating at the highly congested 2.4 GHz band or the less congested 5 GHz band, wireless-AD (a.k.a. WiGig) operates at a new 60 GHz band. The key selling point of this wireless-AD network technology is that it is able to provide an unprecedented  throughput as high as 7 Gbps, which is even much more faster than the wired Gigabit Ethernet network!

However, the wireless-AD network, operating at 60 GHz band, has even shorter range than the 5 GHz band WiFi, and it find itself more difficult to penetrate through walls and other physical obstacles. In addition, its performance is degraded by the amount of oxygen in the air!

With these limitation, wireless-AD might require an open space environment with less oxygen in the air (such as at high altitude places) to transmit data at high speed to nearby devices that support the technology.

Some possible uses of wireless-AD could be media server transferring super UHD movie to nearby TV, "wireless external SSD hard disk", "wireless thumb drive without USB need", etc.

TP-Link has already come out with the Talon AD7200 Multi-Band WiFi Router that supports wireless-AD technology. However, many wireless devices are yet to catch up with this new technology.

Anyhow, it is already supported in the Qualcomm Snapdragon 820 processor which is inside the Samsung Galaxy S7, Samsung Galaxy S7 Edge, LG G5, Moto Z, Sony Xperia X Performance, XiaoMi Mi 5, and the newly launched HTC 10.

It is expected to be also supported in the upcoming Samsung Galaxy Note 7. However, it is still unclear whether Apple iPhone 7 will support wireless-AD or not.

How to Boost Your Rainy Day Fund

A rainy day fund is important as it will serve as your back up plan if you lose your job or when unexpected expenses arise. Get started as soon as you can even if you only have a little to put in. What matters is that you are doing something now that will benefit you in the future!


1. Prevent Late Payment Fees

Late payment fees may not seem like much, but you will be surprised at how quickly they add up. Put the money supposedly for the payment of late fees into good use by putting it in your emergency fund instead.


2. Automate Your Savings

Stop making excuses for setting aside your savings by having automated deductions from your payroll account to your rainy day account. You can always control how much you put in, this is just a sure fire way that money is being added to your fund monthly.


3. Avoid Debt

Avoid spending money that you do not have to avoid debt. Although there are good and bad debts, it is still important to assess if you really need to borrow money or if you are thinking of unnecessary expenses. You will be able to save more money when you have less things to pay for.


4. Treat Your Monthly Savings like a Bill

Think of your savings as a bill that you cannot afford to miss paying, just like your rent, electricity,
or phone bill. Better yet, once you have finished paying for something costly, such as credit card debt, car payment, or student loan, shift that payment to your savings account instead.


5. Review Your Daily and Monthly Expenses

It is easy to overlook expenses such as your daily cup of coffee, weekly manicure, monthly TV/movie subscription .Going over your expenses will help you realize what is really worth spending on and what is not. This will help you cut off on your spending give your savings a boost.

My TP-Link AC2600 wireless dual band gigabit router Archer C2600 with TM UniFi and Maxis Home Fibre support

I have been using TP-Link TL-WDR3600 dual band wireless-N router for home Internet access for about 3 years, and have just changed it with a new TP-Link AC2600 dual band wireless-AC router.

The TL-WDR3600 router is still functioning well, and I changed it for better home network experience. The reason for the change includes:

  • The 5GHz WiFi band of TL-WDR3600 has a short coverage area. I can only connect to this 5GHz band when my mobile device is near to the router. Further away, the connection speed on 5GHz band dropped drastically, and I ended up only have the choice of using the 2.4GHz band.
  • The TL-WDR3600 is a wireless-N router and does not support wireless-AC connection. As more and more wireless devices at my home are supported with dual band and wireless-AC, I have to retire it and change to a newer router with wireless-AC support to enjoy the benefit of wireless-AC network and new features such as Beamforming and MU-MIMO. I have chosen the Archer C2600 as its successor.
  • The price I paid for the TL-WDR3600 3 years ago was RM17x. Depreciating this cost over a 3 years period, it cost me less than RM60 per year. I don't feel financially guilty to replace it with a better one after using it for over thousand days.
Other than the limitation on 5GHz band coverage and lacking of wireless-AC support, I would say the TL-WDR3600 is a great WiFi router with stable, consistence and quality performance.

Coming on stage is my new TP-Link Archer C2600 router, which I purchased online at the price of RM68x (RM64x +6% GST) with Hari Raya promotion. At the front cover of its packaging box, there is a red sticker about its 2 years warranty support, and a blue sticker stating its UniFi and Maxis Fibre support.


At the back of the box, there is a comparison table for Archer 2600, Archer C9 and Archer C5.


I have also made a comparison table for Archer C7, Archer C8 and Archer C9 in March 2016. (Yeah, I have been surveying and researching around for the router replacement for quite some times, before finalized to this Archer C2600.)

The size of this Archer C2600 is larger than I expected. It is 10.4" X 7.8" which is about the size of a 10-inch netbook.


It has a larger power adaptor than the WDR-3600 too, and is of the same type with the laptop power adaptor. The adaptor converts AC current from wall socket into 12V/4A DC supply to power up the router.

The Archer C2600 is a MU-MIMO router with 4 antennas, which mean it is able to individually serve up to 4 MU-MIMO supported devices at full bandwidth on the 2.4GHz band and another 4 MU-MIMO on the 5GHz band. If the connecting wireless device does not support MU-MIMO, or the amount of MU-MIMO connections at the router has reached the maximum, the connection will fall into SU-MIMO mode, which means its connection bandwidth will be shared with other SU-MIMO connected devices. (For MU-MIMO routers, the more antenna the merrier, so this type of wireless routers usually have more antennas than the older non-MU-MIMO routers)

The Archer C2600 also comes with a modern looking web user interface, which looks nicer than the traditional TP-Link web interface for router administration. Anyhow, there is not much different in features and functionalities between the newer and older interfaces.


Setting up for UniFi IPTV is much easier than before, just a 2-step action of select and save.


Special note on turning on the UniFi IPTV setting:
  • Do not access the router administration web interface by connecting your PC to LAN Port #1 of the router, you should connect your HyppTV STB to that port instead. If you connect your PC to that port, you will end up unable to access the administration web interface after you click on the Save button, because that port will be assigned to a separate VLAN.
  • There is an option for IGMP Version 2 and Version 3. If you choose IGMP V3, your Internet link will be down. Your Internet link can only work properly with IGMP V2.
  • Certain function of the router, such as QoS, will need to be disabled once you enable the IPTV setting. Probably because they are not compatible with each other.
This Archer C2600 also supports the TP-Link Tether mobile app for you to manage it with your smartphone.



My experience of using the Archer C2600:
  • The LED is less brighter than the WDR-3600, which is good after you turned off all your lights for sleeping at night. In fact, the LED of the Archer C2600 can be configured to turn off by itself during sleeping time too. There is also a button on it to manually turn the LED lights on/off.
  • The 5GHz band coverage improved a lot. Now my Samsung UHD 4K smart TV downstairs is able to connect with it using the 5GHz band. Previously it can only connect with my WDR-3600 using the 2.4GHz band.
  • The overall WiFi coverage (2.4GHz band and 5GHz band) is much larger than the WDR-3600 too. Previously I can only get a poor 2.4GHz connection with very low speed at my car poach area outside the building, which is a few walls and some distance away from the location of the router. Now my mobile devices still able to detect the 2.4GHz WiFi with moderate signal at the car poach, and able to connect to the router at speed of single digit Mbps only. The 5GHz WiFi is also detected but signal is much weaker than the 2.4GHz. 
  • The connection speed improved a lot too. My HTC One M8 smartphone used to get a 150Mbps connection at home, now can get a 433Mbps connection. My newer Samsung Galaxy Note 5 smartphone is able to get a 866Mbps connection, with its dual channel support.
  • My external harddisk connected to the router's USB 3.0 port has faster read/write speed too. Time taken to copy large file is shorter.

Therefore, I can say that the performance of this Archer C2600 wireless router is as advertised. At the price of RM68x, it really worth the upgrade from WDR-3600.

Understanding Wireless-AC bandwidth you can get from 802.11ac WiFi routers

Wireless-AC (IEEE 802.11ac), a.k.a. Very High Throughput (VHT) is the successor of the Wireless-N WiFi technology, and is the mainstream technology supported by today's WiFi routers and wireless networked devices including smartphones, tablets, laptops, PC wireless cards, smart TVs, smart CCTVs, etc.


As a layman, we always see the wireless-AC device rated with AC followed by a number, such as AC2600. What does that number tell us about the supported bandwidth of the device? Well, the number is actually a close figure to the total bandwidth of all its wireless bands added up together.

Bandwidth is the maximum available network connection speed of two connected devices. The actual connection speed (i.e. throughput) between the two connected devices is equal or lower than the supported bandwidth of the connection. The throughput is usually lower than the bandwidth due to shared connections, distance, surrounding interference, obstacle in-between, etc.

The wireless-AC network can operate in both the "traditional" 2.4GHz frequency band as well as the 5GHz frequency band. The 2.4GHz band is usually congested with the older wireless-b/g/n networks using the same band for wireless data transmission.

Wireless-AC routers or access points are dual band WiFi devices, supporting wireless connections with both the 2.4GHz and 5GHz frequency bands.

The newer AC3200 and AC5300 routers support two 5GHz bands instead of one, making them a triple band WiFi devices.

The table below shows the bandwidth of each of the bands for the common wireless-AC types.


Let's say your smartphone is connected to an AC600 router (the 1st one in above list) using the 2.4GHz band, the maximum connection speed the phone can obtain is 150Mbps. If it is connected to the same router using the 5GHz band, the maximum connection speed is 433Mbps.

If you are buying an AC2600 router (last 4th in above list), you can expect your wireless-AC supported devices connected with it using 2.4GHz band to have WiFi speed of up to 800Mbps, and if connected using 5GHz band, can reach a maximum speed to 1733Mbps, which is even much faster than the Cat-6 cable wired gigabit network (1000Mbps) connected to its gigabit network port.

Note that the maximum bandwidth in each of the bands in the table above is a combination of bandwidth delivered by one or multiple channels running in Channel Width of 20Mhz, 40Mhz, 80Mhz or 160Mhz. Connection of two linked WiFi devices must be established using the same channel number.

In wireless-AC network, each channel in 2.4GHz band supports a bandwidth of 150Mbps or 200Mbps; and each channel in 5GHz band supports a bandwidth of 433Mbps.

An AC2600 router such as the TP-Link Archer C2600 could support 4 channels in 2.4GHz band (4 x 200Mbps = 800Mbps) and 4 channels in 5GHz band (4 x 433Mbps = 1732Mbps). If your smartphone only support 2 channels in 5GHz band, then the maximum connection speed with the AC2600 router is only 2 x 433Mbps = 866Mbps instead of the full channel 1733Mbps. If your smartphone also support 4 channels in 5GHz band, then it is possible for you to achieve 1733Mbps connection speed.

Note that WiFi is a kind of local area network (LAN). The internet access speed you can get from the router is still restricted to the bandwidth you subscribed with your ISP, which is normally lower. Anyhow, a fast wireless-AC connection enables network data transfer between devices within the local network to be speedy. This will enable smooth ultra-high definition video streaming to your 4K smart TV from another device.

Rodger 7-point plan and Munro 5-fold grading system

Attention job interviewers and interviewees, the information below could be useful to you to successfully get the right person (for interviewers) or win your dream job (for interviewees).

Many HR adopts 2 important person specification models by Alec Rodger and John Munro Fraser respectively to match a job description with the ideal candidate to fill the job. Each of them gives certain headings under which the attributes of the ideal person can be classified.

Person specification is a profile of the personal skills and characteristics to look for in the recruitment and selection process.

Rodger's 7-point plan:

  • Physical make-up: health, appearance, bearing, speech and manner.
  • Attainments: education, qualifications, experience.
  • General intelligence: ability to define and solve problems.
  • Special aptitudes: skills, attributes or competencies relevant to the job.
  • Interests: work related or leisure pursuits that may have a bearing on the job.
  • Disposition: influence over others, steadiness, dependability, self-reliance.
  • Circumstances: any special demands of the job, such as ability to work unsocial hours, travel abroad, etc.

Munro's 5-fold grading system:
  • Impact on others people: similar to Rodger's "physical make-up" specification.
  • Qualifications and experience: similar to Rodger's "attainments" specification.
  • Innate abilities and aptitude: quickness of comprehension and aptitude for learning.
  • Motivation: individual goals, consistency and determination to succeed in the workplace.
  • Adjustment: emotional stability, ability to stand up to stress and ability to get on with people.

Scholarship2u website and Scholarship Fair 2016

Scholarships2u.com is an interesting website, acting as a one-stop gateway portal to scholarship information and application for Malaysian students of secondary school, college, or university up to Master degree, to study either locally or abroad.


The website aims to make finding the right college and scholarship faster than before with just a click of the button. Students can apply to scholarship offered by multiple institutions, and are required to sit for a scholarship test as assessment to the application.

The basic criteria to meet scholarship eligibility are school transcripts, achievements, family background and etc. The criteria, however, differs from country to country, state to state and even college to college.

The website is a good initiative for parents and students seeking for scholarship as financial aid to study. However, I find that improvement could be made for the website to list the scholarships offered in a better way, and to provide a better search function. Apparently, the website is using Wordpress as its platform, which has many limitation for its feature expansion and future growth.

The website is organizing Scholarship Fair 2016 with over RM10 million worth of scholarship to be offered for studying in  world class schools, colleges and universities from Australia, Malaysia, Switzerland, USA and United Kingdom.

Date: 23 July 2016 (Saturday)
Time: 1pm - 6pm
Venue: Eastin Hotel, Petaling Jaya
Admission: Free for first 1,000 registrations

For registration and more information about the Scholarship Fair 2016, click here to visit to Scholarships2u.com website.

Updated the firmware of my Samsung Xpress M2885FW printer to version 3.00.01.13

I have just updated the firmware of my Samsung Xpress M2885FW printer to version 3.00.01.13.

You can download the latest firmware from Samsung support webpage of this MFP here.

Firmware update can be done via the Samsung SyncThru Web Service, by accessing the printer's IP address using your web browser.

Note that you need to login as administrator user in order to perform the firmware update.

Here are the steps to perform the update:

  • Download the latest firmware, and unzip the file.
  • Locate the firmware file with extension .HD, such as M2885_V3.00.01.13.hd.
  • Open your web browser and access to the printer's SyncThru Web Service.
  • Login as administrator.
  • Go to Maintenance > Firmware Upgrade.
  • Click the Upgrade Wizard button.
  • Select the firmware file, e.g. M2885_V3.00.01.13.hd.
  • The file will be uploaded, and the firmware update process will begin.
  • The printer will restart, followed by the firmware reflash procedure.
  • Upon successful update, you can check the firmware information in Maintenance > Firmware Version screen.

And here is the changelog of the firmware for this printer for your reference.




Upgraded my home MFP to Samsung Xpress SL-M2885FW/XSS mono multifunction laser-class LED printer from Dell 1355cn colour multifunction LED printer

My Dell 1355cn colour multifunction laser-class LED printer has served me for more than 4 years before I hit with a paper jam problem that I'm unable to resolve by myself (probably due to faulty in either its sensor or paper feed roller alignment).

Considering its high toner price and I found difficulty to get a printer repair shop who are willing to repair this Dell printer, I decided to replace it with a new Samsung Xpress SL-M2885FW/XSS mono multifunction (print/scan/copy/fax) laser-class LED printer.

 


I have chosen a mono laser printer this time rather than a colour laser printer, as I found out that I seldom need to do colour printing. This BLI award-winning mono laser MFP which cost me RM698 (inclusive 6% GST) is much cheaper than the colour laser MFP available in the market. In addition, it only has black toner to replace instead of 4 toners which cost a lot when replaced at the same time.

One of the beauty of this Samsung M2885FW printer is that its imaging unit is separated from the toner, which helps to bring down the cost of the toner. The imaging drum unit MLT-R116 has a page yield of up to 9,000 pages and cost around RM175 for replacement, while its high-yield toner MLT-D116L  with page yield of up to 3,000 pages cost about the same price with the imaging unit. There is an alternative standard-yield toner MLT-D116S with page yield of up to 1,200 pages cost around RM100 only.

The easiest way to setup this Samsung M2885FW printer is to first connect it to the computer using USB cable, configure its TCP/IP settings so that it is accessible with network cable or WiFi LAN. The printer also supports WiFi setup using WPS method.

There are 2 ways to obtain and install its required drivers and software applications. One way is to install from its installation CD, another way is to install the Samsung Printer Software Installer and Samsung Printer Diagnostics which you can download from Samsung support website for SL-M2885FW/XSS.



You can make use of the Samsung Printer Diagnostics software to install and update the drivers and related applications to the latest version.


Other ways to setup the printer's TCP/IP network settings including using its control panel with 2-line LED display, which might not be convenient, and to connect to the printer using WiFi Direct, then continue with the configuration, which might need some technical know-how before the attempt succeed.

There are 2 important software that you need to install namely Samsung Easy Printer Manager and Samsung Easy Document Creator.

The Samsung Easy Printer Manager has 2 modes. The Basic Mode (or I call it end-user mode) is a clean and straightforward screen that tells you the printer's status, and provides quick button access to its scanner functions (which handled by the Samsung Easy Document Creator application), fax functions, user's guide (which is a comprehensive user manual) and some other basic functions.


The Advanced Mode (or I call it administrator mode) provides more detailed information about the printer, including its serial number. It also allows you to perform some settings configuration here.


There is a reason I said setting up TCP/IP for the printer is important. Apart from making the printer accessible via the network once the TCP/IP setting is done, it also enables you to have access to its powerful Samsung SyncThru Web Service which you access by connecting to port 80 of the printer's IP address using your web browser.


The number of information you can get in SyncThru Web Service is even more than Samsung Easy Printer Manager Advanced Mode. It also provides you much more control to the settings of the printer.

You can gain even more access by login as administrator in SyncThru Web Service. The default username is admin and its default password is sec00000. Once logged in, you can replace this username and password with your own.

You can also perform print, scan or fax function from your mobile device through the Android app called Samsung Mobile Print. If you are using iPhone or iPad, there is Samsung Mobile Print for iOS too.


What I like about this printer?
  • It prints and/or copies really fast, at speed of up to 28ppm. Much faster than the Dell 1355cn.
  • Its print output is of high quality. Resolution can be as high as 4800x600 dpi.
  • Its scanner support high resolution of up to 1200x1200 dpi optical, and 4800x4800 dpi maximum.
  • It has built-in support for automated double-sided printing, which is a feature normally available in printers of higher range.
  • It has built-in support for ID copy to easily copy double-sided cards (e.g. IC, driving license, business card, ...) onto the same page of A4 paper.
  • It has built-in support for Google Cloud Print, Samsung Cloud Print, and Apple AirPrint.
  • It is small in size, even slightly smaller than the Dell 1355cn.
  • It has low power consumption of 1.6W during power save mode, 2.4Wwhen sleeping with WiFi direct on, 50W during standby, and 400W when printing.
  • Its paper tray is of drawer type, not exposing the papers in front of the printer. The tray has input capacity of up to 250 sheets of papers.
  • It has easy to use Eco Mode which helps to save toner and/or paper usage.

What I dislike about this printer?
  • Its 2-line LCD display panel has limited display area. It is not practical to perform setting directly using its control panel.
  • When putting in A4 paper in its paper tray, there is still slight exposure of the paper at the back of the printer.
  • It supports NFC, which needs to function together with WiFi Direct. However, my phone's NFC contact with the printer most of the time not successful to bring up the Samsung Mobile Print app. It is not easy to make use of this function.
  • The Samsung Printer Installer unable to detect and download the latest firmware for the printer, and the Scanner Driver is always in "update needed" state even if the latest version already installed successfully.
