I got this error when I upgrade a Java Installation in Windows 10. I got the error 1603, even I restarted the computers a number of times. Finally, according to the instructions from java, I uninstalled the whole Java runtime and downloaded the offline installer rather than using online upgrade. Then that works again!

After I upgraded Xamarin Forms 2.0, I got an error about missing class.jar under a local folder about AppCompat library. I tried to remove and add Xamarin Forms Library. The final solution is deleting the whole AppCompat library under the local folder

Last night, there was an apple event. Thus, this morning, I got up and checked their website, I am quite disappointed. Mainly, they are going to release two new products. Firstly, they will release a new version of iPhone, iPhone SE . That is a lower end product than iPhone 6s and looks like iPhone 4. Secondly, a new version of iPad Pro is coming, that has a smaller screen, 9-7 inch screen. I did not feel exciting for these two products. Also, I was looking forward to a hardware refresh for Mac Mini and Macbook Pro. They are not using the latest version of Intel CPU, skylake yet. But this event has not mentioned any plans about that at all.

I just built a website in Bootstrap, I fount the mobile menu won't be collapsing after I clicked menu button. I tested in a number of mobile platforms, all of them are not working. After I reviewed the code, actually, that caused by referencing the bootstrap js file two times. My theory is the mobile menu won't be collapsing if the js file references more than once in the html page.

This is another new toy I bought in Hong Kong. Actually, that is for work. This toy is very useful for work. This hard disk is using SSD rather than mobile hard disk, so this is more portable than a normal Mobile hard disk, this is a little heavier than a USB thumb disk. Moreover, the speed is much faster than the USB thumb disk. This hard disk have around 36 MB per second, which is a little bit faster than the Normal Hard Disk. Finally, I carried this hard disk to work every day as the extended data storage!
