Thank you for clarifying, working great here!

Re: Perlin noise generator in PHP

Aquila. I fixed your generator! It had two problems that I addressed.

1. Negative values, when fractional, were backwards (but only fractions were backwards) - when you get the integer value at the very beginning of the noise, floor it - for both x and y. This way, -.75 doesn't have 0 as its 'integer' nearest it, it instead has -1, so it doesn't become a repeat of .75.

2. The problem some have been talking about running out of perlin is due to the noise() function - when the combination $x * $y * 57 gets over about an absolute value of 4360 or so (-4360 in the other direction) the noise stops. What I did is send $n back the other direction like this:

while(abs($n)>4360) $n = $n - (($n-(4360*($n/abs($n))))*2);

Right after $n is calculated in the noise function. This creates on a large scale a 'reflection'. Perlin himself said that repeating on a large scale is something that the Perlin Noise doesn't care much about, but I'd imagine if you'd want it to be super-solid, you would need 9 sets of random values; Whenever $n is greater than ~4360 (don't know the exact value) depending on your $x and $y values, you choose different sets of r1,r2,r3. This way, you can eliminate the repeat.

I'm at work now and don't have much time. You have to implement the other actions.

Did you setup the database properly, I don't see the username in the error. Check this example config: http://code.google.com/p/kohan...

Hi Lucas. Unfortunately, I've abandoned the tutorial a long time ago. If you have any particular question about the code you can ask it here or on the blog itself. I'll do my best to help.

Hello AquilaX!
I'm from Poland. I didn't know how to find you but I did. Do you remember your blog http://kohana-tutorial.blogspo... ?
I started to make your Kohana Hacker News but I have problem. I don't know where put below this code because you didn't type exactly. "Let's also add a method to get all the news for the home page: " Do you have maybe FB or ICQ ? I wanted to talk if I have problems.

Regards from Poland Lucas

Yep, same here, only the two top rows are getting random data. After that, it evens out to a solid color.

wow, great solution. This saved me a lot of time. thanks alot

Re: MySQL UNION DISTINCT with result priority

AquilaX — Wed, 17 Nov 2010 08:02:59 -0000

Yes there is just enclose everything in one select:

SELECT(
SELECT... whatever
) as outer LIMIT 10;

Re: MySQL UNION DISTINCT with result priority

Sunny — Wed, 17 Nov 2010 07:24:14 -0000

Actually, I tested it:
By default first query in union has top priority and so on.

The problem I am facing now is:
I want 12 results on every page.
So, Is there a method by which I can give Limit to whole query not just in every union query.
