How to disable UAC in Windows Vista

Basic method: Control Panel

1. Turn it off in User accounts.
• Now, Microsoft highly recommends that you do not do this.  After you ignore them and do it anyway, a scary little red X shield icon plants itself in your Taskbar, visually screaming at you about the security risk.
2. In Security Center, choose "Change the way Security Center alerts me" and then "Don't notify me and don't display the icon (not recommended)"

Health-index formulas

Body Mass Index (BMI)

The formulae universally used in medicine produce a unit of measure of kg/m².

HP calculator's solver equation:

BMI = KG÷SQ(CM÷100)

• KG = kilograms
• CM = centimeters 

Calculator technique

ส่วนใหญ่มักจะคำนวณค่าส่วนสูงยกกำลังสองก่อน แล้วค่อยมาตั้งค่าน้ำหนักหารด้วยค่ากำลังสอง

วิธีที่ง่ายกว่าคือ

1. ตั้งค่าน้ำหน้ก (kg)
2. หารส่วนสูง (m: ปกติบอกเป็น cm ก็ทดทศนิยม 2 ตำแหน่งไปเลย)
3. หารส่วนสูงซ้ำอีกที

Cholesterol-HDL-LDL-Triglyceride equation
HP-calculator solver:
CHOL = HDL+LDL+TGCR/5

How to add multiple contacts to a group in Google Contacts

Current generally-known practice:

1. Add contact into my/all contacts, if it has never been in yet -- one by one.
2. Select contact(s) from my/all contacts or existing groups, and add to desired group.

Solution: use "Import" function

1. Create CSV file (see: "Creating or editing CSV files").  Just single-column list with header (first line) "Email address" also works. 
2. From GMail or Google-apps, go to Contacts.
3. Click function (at right-end of action bar).
4. Input the CSV file.
5. Enable "Also add these imported contacts to:" and choose (or create new) desired group.
6. Done.  The process will also merged contacts with ones already in Google address book properly.
