Early of this year, I went to Hong Kong. During this trip, I bought a new toy, xiaomi miBrand. This is a fitiness tracker. It can track my steps and sleep m pattern. I love it. That is very light, a bit little lighter than my old watch. Moreover, its battery can last for a month. In addition, it supports all Bluetooth phones, you do not require to use xiaomi phones. All you need to download their fitness app, miFitness. Lastly, it only costed around HKD$150.
Well, there still are some drawbacks. Firstly, it cannot track heart bit. Besides, you has to use their fitness app. This is using a chinese map provider, it cannot track my running track in Australia. However, it only cost HKD$150, I still think that is a good entry point to try this kind of fitness armbrand.

I bought stream 13 in Hong Kong for only HKD$2100. Well, that is not good enough to be a develop box. However, that is very lightweight(around 1.5kg), long battery life and inexpensive. That is very suitable to carry around. Although that is not very powerful, it is still good enough to remote desktop to my pc at our office for work and a server in a data center. I used it to do a few times for restarting servers. It already saved me a number of times to drive back to home. The fuel and time has already paid the cost to buy this laptop!

Whatsapp started to roll out their VOIP feature to a group of selected users for a trial. I and my wife are one of them. We tried that today. the voice are quite clear, I think that is better than Facebook VOIP. We started to use less phone calls, more VOIP calls.
Note that, we are still using 3G, I think if we are using 4G networks, that will be much better.

Yesterday, I setup a new Core i3 PC with 4GB RAM for a client. That is not a good specification for a developer use. However, I found it is faster than the most of Core i5 PCs in my office, they are just one generation older.

I tried WhatsApp, Web version, that is very easy to use. Firstly, go to https://web.whatsapp.com/. Then open WhatsApp in my phone, click Menu->WhatsApp. Finally, Scanning QR code by using phone. Then it will works.
Now, I can send and receive messages in my computer. Using a bigger screen and a full-size keyboard, that is more comfortable to read and reply message. Also, you only need to drag and drop the files to the images into the message window, then the images will be sent out.
