fastcgi on godaddy gotcha

I'm a plain person and completely out of net epoch. But I'm a guy with curiosity. I want to know how fastcgi works. So I try it on godaddy.

First, I find this link
http://forums.hostingplayground.com/showthread.php?t=348
where a piece of test code is posted:

#!/usr/local/bin/ruby

require 'rubygems'
require 'fcgi'

counter = 0

FCGI.each_cgi('html3') do |cgi|
   counter += 1
   cgi.out {
     cgi.html {
       cgi.body {
         cgi.h1 { "Hello World!" } +
         cgi.p { "Counter: #{counter}" }
       }
     }
   }
end

And I put this piece in html/cgi directory. It works but works like regular cgi? What's wrong here? At least I trust godaddy's claim on supporting fastcgi.

Then, I come across a page that change the file name extension. It was a ruby file but with .cgi as the extension. I realized that I have to try some new extension. So I rename the file with .fcgi extension. And it works!

Luxury cookware

Luxury cookware

One day I came across copper cookware. And I just cannot forget it. Despair of its high price, It do remind me my old physical course that copper conduct the heat most efficiently. So I want to do a research on it to see where I can buy and how is the market looks like.

There is great thread on this. Here is the link:
http://www.cheftalk.com/t/53919/mauviel-vs-williams-sonoma-mauviel
If you search sonoma and e.dehillerin, you will find it.

There are a lot of other topics about the copper cookware.

In general, there are following top cookware brand in stats. All-Clad, Williams-Sonoma and mauvielusa. However, people tend to directly order the copper cookware from E.Dehillerin in France.

It’s said that it’s much cheaper to order them from France.

Regarding to the product, the thicker the better. The thick line from E.Dehillerin is 2.5mm thick copper. It’s either with stainless-steel or tin. And people like stainless-steel better it seems. And for the same capacity, ss is priced higher than tin. But personally, I prefer tin. Although tin looks odd, it’s used to cook for a long history and the copper with tin is looked more beautiful, more like hand made.

More on SS or tin is that for home use, SS is enough and convenient. And if I choose lined with tin. Then there is additional service. Once in awhile, you need to retinning, which is a process that apply tin to the cookware again.

You can download their catalog as it contains more information than the web page shown. Then you have to fill in the form to order and then they will send you a performa. Then you fax back your credit card number, signature and expiration date.

Enjoy cooking!

How to buy a car.

When I realize with my broken sedan, I start to think about if I want to buy a new car, what can I do?

Real experience:
One night in August, 2012, I am driving down I93 with my wife. It's raining heavily outside and I barely can see the lane. Crazy or brave people are everywhere and they are also driving along me and then pass me. Without any sign, a van turn right a little bit and then turn left sharply. His tail swings out and his light is staring at me. It should happen so quick. But my mind was so clear that the time seems slowing down. I even had a time to look at the dashboard. The speed before I pushed the brake was around 50m/h.

I'm a positive person, even after this fatal accident. Of course I won't buy a van unless I have a den of mini people. Then I ask myself the question:

• Should I buy a SUV/Cross-over?
• Should I buy AWD car?

From my point of view, no, I won't  buy a SUV/Cross-over. There are couple of reasons I don't want to (maybe I change my mind soon or later):

1. Center of gravity is higher. This is not only to say the car is more probably to fall over but also to say if you feel it's going to fall over it will do fall over. You don't have much alarm range compared to sedan.
2. SUV? They are all over the streets. I don't want to add one by myself.
3. Probably, probably SUV will cost more on gas.
4. Most importantly, I don't have the budget for this kind of luxury! Ok. I don't have budget for a full size SUV. And for mid-size SUV? Grrr, passage space is like a mid-size sedan...then why choose them.

However, SUV do offer a safety advantage over sedan:

SUV is taller than a sedan.

 This comes to the point that the mount point of front light of a SUV is higher than a sedan. When driving a SUV through thousand needle, you should be less affected by the second wave of needle by the front car. This helps a lot in that situation.

TBD

Buying a car is only half the homework. The other half goes to maintenance. I find a link which saves my time. I copy the table here:

From the table, it seems that the best option on warranty is from Hyundai and Mitsubishi. But I guess I need more info about adding price for the warranty.

1. Never use coordinate descent, use something like BFGS.
