So I have been using the Vaio notebook for about a week now. I started to love it because of it being light and it is very convenient for me to bring it anywhere. The display is so much brighter and the razor thin LCD makes this notebook a plus. The carbon fiber outer casing is indeed eye catching. I also love the 2GB memory and a powerful Intel core 2 duo that this notebook has. Overall I think it is worth the buy for about 2700 usd.

In verilog, there are two types of reset, synchronous reset and asynchronous reset. In synchronous reset, reset is sampled with respect to clock, whereas in asynchronous reset, reset is not sampled with respect to clock. There are advantages and disadvanteges of using asynchronous reset and they are it requires less gates to implement, does not requires clock to be active always and it is fast. However it suffers from metastability problem.
An asynchronous D Flip Flop:
module dff_async_reset(data,clk,reset,q);
input data, clk, reset;
output q;
reg q;always @(posedge clk or negedge reset) //for asynchronous
if (~reset) begin
q = 1′b0;
end else begin
q = data;
endendmodule
A synchronous D Flip Flop:
module dff_sync_reset(data,clk,reset,q);
input data, clk, reset;
output q;
reg q;always @ (posedge clk)
if (~reset) begin
q = 1′b0;
end else begin
q = data;
end
endmodule
Notice the always block which distinguishes between asynchronous and synchronous reset.

I am planning to get a new notebook within this week. My current notebook is a Toshiba. When I bought the notebook, it was not the high-end. I have a couple of complains about it. The complains are that the notebook is too heavy for normal outdoor use, the computer got heated too fast and it has a noisy fan. Afterall, the price that I paid for the Toshiba makes me accept those disadvantages. I am always been a fan of sony products. So considering this is my third notebook upgrade, I am thinking of getting the Sony Vaio SZ series. I am looking for a notebook that is ultra-light and not noisy. The SZ series has all of those met. Therefore, the SZ 360 or 370 Premium Series is now at the top of my shopping list. I have done my research and I am now 80% sure that this is the notebook I am getting this week. Nevertheless I am always open for other brands and inputs from the readers.

So I got my wisdom tooth extracted 2 days ago. The procedure itself is not painful. Only a few pinches of needles to make my mouth numb. After that, no pain at all. Feel some pushing and cracking and in a few minutes my tooth are out. I was given a prescription and that was about it. Some pills to be taken as antibiotics and pain relief. A lot of bleeding in the first day but not after that. Now I am feeling a little discomfort while eating, a lot of things that I could not eat, otherwise everything is okay now. I have to go back for a follow up in seven days. It was not that bad afterall
