Divisibility Rules

Hello guys! It has been a long time since my last blog!

Today I’m going to share some interesting rules in Mathematics that is about “How to determine whether a given integer is divisible by a fixed divisor without actually performing the division”.

Windows PC SSD Upgrade 硬碟升級

I have a 6 years old desktop Windows PC in my home that is mainly used by my wife. However, as my little boy is getting older and needed to use the computer as well, it became quite inconvenient to have them sitting in front of the desktop. I ended up buying notebook computers for them subsequently.

Despite that desktop PC is a little bit old, it still got the works perfectly done if just for daily home use or web surfing. The only downside is the slow PC startup time and that’s why I decided to replace the hard disk with a SSD.

家中一台已購置六年多的桌面 Windows PC 主要是給太太使用,但隨著兒子長大並開始接觸電腦,要他們安坐書枱前便有點不太方便,於是便轉用了筆記簿電腦。

雖然這台電腦有點舊,但如只用作日常的資料處理及上網,它還是升任有餘。唯一不足處是開機時間稍長,最近便決定為它的硬碟升級至 SSD。
