That is the reason:  i7 3610QM (4 cores + 4 HTs) and  i7 5500u (2 cores + 2 HTs).

Samsung S6 10 May 2015

Samsung Galaxy S6

I have just bought a new Samsung S6. I still keep my S3 and S4 because I can only get less than RM300 each if I want to trade-in my S3 and S4.

TSL Marketing & Enterprise (U-Mobile) at Ampang Point Mall, Kuala Lumpur.

In terms of speed, you won't see a lot of differences between S4 and S6 because both have 8 processors. However, S4 and S6 have 2GB and 3GB RAM, respectively.

Since my S4 still uses Android 4.4.2 Kit-Kit, I have noticed that S6 (Android 5.0.2 Lollipop) is more responsive and stable than S4. I really hope Samsung will release an update for S4 in the future.

Now, let us talk about the camera. Amazingly, S6 is able to focus in less than 0.5 second. Wow!!! The photos are as sharp as a DSLR camera.

How about the video? S6 supports VGA, HD, Full HD and 4K videos. Hmmmmm..

In other words, you can leave your DSLRs at home when travelling. Definitely, a DSLR camera can extend its zooming range depending on the lens that you use. You can't do that with S6 or any phones.

S6 also has a very special shooting mode known as Pro in which you adjust its setting similar to a DSLR camera. Totally awesome!!!

You can also uninstall Nvidia drivers (version 340.52 or later) from Control Panel\All Control Panel Items\Programs and Features. Restart your computer.

Then, go to Device Manager and disable

How to use Sony ADPMAA Sony DSLT A58

How to use Sony ADPMAA with Sony DSLT-A58?

You have to change settings of your camera and external flash unit according to your lens.

a) If you use kit lens (18-55mm) or prime lens (50mm) - just set your shutter speed from 1/100 to 1/160. You don't have to use HSS.

b) if you use zoom lenses like Sony SAL75300 (75-300mm) - just set your shutter speed starting from 1/250 (or higher). In order to do that, you have to use HSS in manual flash mode (Sony F43AM) and you can set the flash power according to your requirement. I love using Sony F43AM flash because the flash "tells" you the distance in meters  from you to the subject matter when you can change its power level.

Multi-Interface Shoe Adapter Sony ADPMAA  supports both TTL and manual modes.

Asus Zenfone 2 the fastest smartphone

Is Asus Zenfone 2 the cheapest and fastest smartphone in 2015?

(I don't make the review. I just share it)

Even though the review used the old model of Intel Atom processor, you can see that Intel Z2460 has defeated Samsung Exynos and Qualcomm Snapdragon. 

Intel Atom processors are also used by many computer manufacturers in their netbooks for so many years. Therefore, the processors are capable enough to handle a multitasking environment of Windows 7 Pro including heavy applications like MS Office 2013, Photoshop, SPSS and many more. (History of netbooks)

More review:

For your information, Samsung S6 uses the latest version of Exynos CPU and Samsung S4 uses Qualcomm Snapdragon.

How to protect facebook before being hacked

How to protect your Facebook before an intruder hacks it?

The first thing that you need to remember is to take these precautions into consideration before your Facebook is hacked by an intruder. If your Facebook has been hacked before seeing this blog, it is quite difficult to regain control of your account.

1) Password
Create a password for Facebook that cannot be guessed by other people. It is recommended that your password should contain at least 4 letters and 4 numbers (with/without 1 or 2 characters).  The most important thing is not to tell anyone your password even your girlfriend.

2) Add several email accounts and mobile numbers.
Make sure all passwords for your email and Facebook accounts are different.

Inside Philips DLP5200 power bank

What can you see inside a power bank?

Philips DLP5200/97

I have just opened my damaged power bank, hoping to replace the batteries. Unfortunately, the size of the battery is not the same like normal AA batteries.

You need to remove the sticker / label on the front cover of the power bank. Then, use a screwdriver to remove the screw. Use a thin ruler to open the casing. As you can see in the last picture that the batteries are larger than the Sanyo rechargeable AA battery.

Samsung Galaxy S4 versus S6

Samsung Galaxy S4 versus Samsung Galaxy S6

The speed of S4 is as (almost) fast as S6 because S4 has 8 cores with 2GB (total RAM), and S6 has 8 cores with 3GB (total RAM). I don't think you will see a lot of improvement in terms of speed unless you really  need the camera because Samsung has slightly improved  S6 camera and video capabilities.

Sony DSLT A58 with ND Variable Filter

Testing Sony DSLT A58  and SAL50f18 with Steinhesier MC UV Filter and Jlens ND Variable Filter (ND2-ND400). I didn't edit the photos. I only added my watermarks and resized from 20MP to 2MP. Just click the photos to view them at 2MP.

Note: I normally use 1/160 or 1/250 shutter speed because it is the highest sync speed for an add-on external flash. However, I didn't use flash in the following tests.

1/160, f/1.8, ISO100, MCUV + ND2 (Min)

1/160, f/1.8, ISO100, MCUV + unknown ND (adjusted)
