I loved to re-build some old computer with Kubuntu. Kubuntu got an UI will be very similar with Windows 10. That is very suitable for Windows Switcher and the performance is much better for Windows 10 in the older specitications. One of the problem is lack of Chinese IME in Kubuntu. I found the solution, if you only require to input chinese for Web Search or you use web app to do the wordprocessing. You can install Google IME in the Chrome as the extension. It has a lot of Chinese IME, such as Cangjie and Pinyin. Moreover, you use mouse to write Chinese character for input too. That is very useful

I finally upgraded to Windows 11 from Windows 10. Generally, no performance is downgraded, and no applications are crashed after the upgrade. The UI looks fresher. But I still feel uncomfortable having the start button and menu in the center of the task bar.

We got Angular, React, Vue.js. Those typescript UI frameworks can provide a rich user experience to the user in a mobile web interface. Do we need to build Mobile App?
Yes! In some situations, that is the truth. For example, if you do not have any native functions from a mobile phone, such as GPS and notifications, you do not need to build any mobile app. Moreover, you spend the time to publish your app in the app store or play store. The users do not need to download the app. You only need to give the URL to your users.
However, if your app is required to access the native features a lot, such as GPS, camera, and notification, I suggest you build a mobile app. The mobile app is better to handle those functions. If you want to have some background tasks in your app, the native app is better in this area too!
Thus, whether you should build a mobile app, that depends on what you want.

Yesterday. Windows 11 is released. The major changes are in the UI. The star button is in the middle, that is more like to MacOS. Moreover, this version comes with Microsoft Teams. I think that is the new normal, work form home trend. Lastly, that is good for us the developers. This version store accpet the traditional windows app! The store got the new design too.

This apple event is mainly about Hardware. new iPhone, iPad and iPad mini. Mainly, there is a new CPU for for iPhone and iPad mini. iPhone does not impressed me a lot. However, the iPad mini, that is quite attractive. It has not any refresh for a while. This times, it has a new CPU A15 with some AI feature. Moreover, the touchID is back! Also, it has USB-C port too, no lighting port anymore. I love it. For iPad, it has a A13 CPU. Moreover, it has iPadOS which are targeting the user to support multitasking, that is very productive!
