Blue Screen of Death

For a long time, I did not get Blue Screen of Death (BSOD) on my computer. I got one last week. As I recounted, I did not install any thing on my laptop. The last software installed on my laptop was Google Chrome about two weeks ago. Now, BSOD appeared twice yesterday and one this morning.

stop 0x0000008e (0xc0000005, 0xBF952937, 0xa854cc00, 0x00000000)

win32k.sys - address BF952937 base at BF800000 DateStamp 48ce513a

Hit F12 on restart to diagnostic. Nothing wrong. I guessed it could be the memory card. Time to shopping for a new memory DRAM.

Update 01/04/2009: After I uninstalled Google Chrome, BSOD went away.

Netbook vs. laptop vs. smart phone

From BusinessWeek "Netbook Sales May Be Cutting Demand For Laptop PCs"

Netbooks typically cost $300 to $500, but prices may slide. Wireless companies such as AT&T (T) and Verizon Wireless may subsidize netbooks if customers sign up for service contracts, just as they do with mobile phones. That could drop netbook prices to as little as $100. AT&T says it's "looking at" making such offers; Verizon Wireless declined to comment.

Yes, the netbooks may cut the demand for laptop for small screen size 14 inches or a desktop but not with the large screen size laptop. If I have a smart phone like iphone with me, why bother to carry with additional devices such as netbook, ipod and digital camera?

Theo trang "CDG: CDMA Worldwide" có ba công ty hiện đang xử dụng kỷ thuật CDMA ở Việt Nam: S-Fone (đầu số 095) và EVN Telecom (đầu số 096) và Hanoi Telecom. Thực ra, Hanoi Telecom (hay HT Mobile) đã chuyển từ kỷ thuật CDMA sang GSM (Ericsson to take over HT Mobile) từ năm 2009. S-Phone hoạt động trên tần số 800Mhz (như Verizon, Alltel). EVN Telecom hoạt động trên tần số 450MHz (theo CDG).

Các kênh phân phối của S-Phone
Mở mạng dùng mạng Sfone các máy xách tay

Các công ty điện thoại di động hàng đầu tại Việt Nam:

Viettel Mobile chiếm 41% thị trường với 5 đầu số: 097, 098, 0168, 0169, 0166
Mobifone chiếm 29% thị trường với 5 đầu số 090, 093, 0122, 0126, 0121
Vinaphone chiếm 24% thị trường có 4 đầu số: 091, 094, 0123 và 0125
S-Fone chiếm 5% thị trường có đầu số: 095

GSM:
Điện thoại di động dùng kỷ thuật GSM có 4 tần số: 850Mhz (USA), 900Mhz (Internationally), 1800Mhz (Internationally) và 1900Mhz (USA)

Trích từ Dual, Tri, or Quad Band GSM Phone?

Two frequencies are 'must have' frequencies - 900 and 1900 MHz. The other two bands are nice to also have, with 1800 MHz typically opening up more of foreign countries than 850 MHz would open up in the US.
Ideally the best solution is to get a quad-band phone with all four bands.

Nếu bạn dùng phone của AT&T hay T-Mobile có cả bốn băng tần (quad-band) 850, 900, 1800, 1900Mhz qua kỷ thuật GSM, bạn có thể dùng tại VN. Cứ việc mua SIM của Viettel, Mobilfone, hay Vinaphone ở Việt Nam gắn vào là alo, alo :)
