I got this error message. Magento Url "http://localhost:8080/magento/" is not accessible

A quick google on this one brought the answer in this link:

http://www.magentocommerce.com/boards/viewthread/8785/

The answer is to make a subtle change on line 139.

Hi, to install 1.0.19870.1, please edit app/code/core/Mage/Install/Model/Installer/Config.php on line 139, replace:

From
$client = new Varien_Http_Client($url. $prefix);
to

$client = new Varien_Http_Client($url.'index.php/' . $prefix)

More details at the link.

Here is what happened to me: I am trying to install magento on my local xampp, and I run into a screen that tells me that I must load curl and mcrypt. No biggie. I look for the php folder, locate the php.ini and uncomment the two lines. I restart apache. I start the installation process again, and guess what? Nothing. I ran into the same problem. I restart again. The same issue.

Time to google this one. I tried several tries until I hit this page:

http://www.zen-cart.com/forum/showthread.php?t=75924

In the thread I learned that the php.ini that xampp uses is not located in c:\xampp\php, but in C:\xampp\apache\bin

Of course it works right after that. :)

How to insert checkboxes into a Ruby on Rails(RoR) view form so that it properly checks the box if the record The solution:

<p><label for="rules_set_commerce_allowed">Commerce allowed</label><br/>
<%= check_box ("rules_set", "commerce_allowed") %>

Before I found this solution, I had figured out this other solution, following some hints found in some site which I can no longer find. It does it job, but it is not as easy as the one above, which is more correct.

< input type="checkbox" id="rules_set_commerce_allowed" name="rules_set[commerce_allowed]" value="2"
<%=  @rules_set.commerce_allowed  == true  ? ck = "checked" : ck = "" %> />

Have I said that, until further notice, they have all been compiled using the cygwin? I love the command line...

/* print Celsius - Fahrenheit table
  for celsius = 0, 20, ..., 300; floating-point version*/

main()
{
	float fahr, celsius;
	int lower, upper, step;

	lower = -10; 	/* lower limit of temperature table */
	upper = 150;  	/* upper limit */
	step = 10;   	/* step size */

	celsius = lower;
	printf("Cel   Fahr\n");
	printf("----------\n");
	while (celsius <= upper){
		fahr = (celsius * (9.0/5.0)) + 32.0;
		printf("%3.0f %6.1f\n", celsius, fahr);
		celsius = celsius + step;
	}
}

Exercise 1-3. Modify the temperature conversion program to print a heading above the table.

#include 

/* print Fahrenheit-Celsius table
  for fahr = 0, 20, ..., 300; floating-point version*/

main()
{
	float fahr, celsius;
	int lower, upper, step;

	lower = 0; 	/* lower limit of temperature table */
	upper = 300;  	/* upper limit */
	step = 20;   	/* step size */

	fahr = lower;
	printf("Fahr  Cel\n");
	printf("----------\n");
	while (fahr <= upper){
		celsius = (5.0/9.0) * (fahr-32.0);
		printf("%3.0f %6.1f\n", fahr, celsius);
		fahr = fahr + step;
	}
}

This is the first exercise of "The C Programming Language" by Kerningham and Ritchie. I will see how many of these I can do and record here. It is probably the most famous one.

Exercise 1-1 Run the "Hello World" program on your system. Experiment with leaving out parts of the program, to see what error messages you get.

#include 

main()
{
	printf("Hello, world\n");
}

Exercise 1-2 Experiment to find out what happens when printf's argument string contains \c, wher c is some character not listed above.

Answer: I get a warning on my compiler, telling me that there is an unknown escape sequence \c, where c is a character not listed above.
