Free Upgrade to Windows 10, Still

I recently purchased a second hand PC, that it came with Windows 7 preinstalled. I have already upgrade the OS in my laptop from Windows 8 to Windows 10 and I am quite used to Windows 10 features, especially the mouse scroll feature that doesn’t require the windows to be on focus. This feature is not available in Windows 7 which really bother me dealing with multi windows.

Microsoft did offer Windows 10 free upgrade for Windows 7 and Windows 8/8.1 user but I missed that window that ended on 29th July 2016. Searching for alternative way for Windows 10 free upgrade, it brought me to a few page saying that the free upgrade is still possible now (end Dec 2016) by accessing this page (link)

Bluetooth Keyboard on Dual Boot Windows and Ubuntu

I’ve recently started to use Apple Wireless (bluetooth) keyboard and it is really a very great keyboard (more info here). I felt like I can type faster and more accurate using this keyboard. The only downside of this keyboard is the lack of dedicated Delete key. To execute a Delete, I will need to press fn + delete key.


Other than that, the main problem of using Bluetooth keyboard and having dual boot Windows 7 and Ubuntu 14.04 is that I will need to re-pair the bluetooth keyboard everytime I switch from one OS to another. The reason behind this is that the device actually create a unique key (store in both the OS and the Keyboard) every time it pair with an OS, but when the OS is being switch to another one, the unique key doesn’t match because the stored unique key on the keyboard is meant for the previous OS.

CT-UNO Cytron Review

Finally there is a local version of Arduino UNO from Malaysia. It is from no other than Malaysia Cytron technologies.

First of all well done to Cytron R&D team.

Lets see what this variety of Arduino features.

From the first look it has a clean layout since it formed with white color. The board seems less congested or spacier.


1. SMD version of Atmega328 looks clean and small. Have better space for more components. Should have better power efficiency

2. Clear view of  TX,RX,LED and PWR LED locations.

3. FTDI USB chips makes fast and stable connection.

4. Features Optibootloader , faster transfer rate

5. Uses Micro B USB. Smaller space consumption. Less wire types to carry around since smart phones uses same type.

6. Has better regulator model for higher current draw.

7. Extra 2.54mm pitch holes at the edge for standard donut board support.

8. Full compatible with standard Arduino shields.


Well the best part , it costs RM56.00 only about $16 only. Good design and quality board for lower pricing.

Good to see Made in Malaysia at the bottom of board.
