I can’t add a product to my wishlist – Magento

Rick — Fri, 13 Jan 2012 08:15:39 +0000

One of our clients at the office had a store and the “wishlist” button in the product view wasn’t working.

The products he was trying to add weren’t in the root category.

You must add your products at least to the root category.

Drop the -moz prefix for border-radius

Rick — Thu, 05 Jan 2012 07:48:51 +0000

Like the -webkit prefix we can now drop the -moz prefix for the border-radius CSS3 style.

The last versions of Mozilla Firefox supports the standard border-radius style.

Before

div{

-moz-border-radius: 5px;
border-radius: 5px;

}

Now

div{

border-radius: 5px;

}

Enjoy!

English and Christmas 2011

Rick — Tue, 20 Dec 2011 09:00:28 +0000

Yesterday I had the last English class of the year.

The teacher handed out the grades and talked to each one of us individually.

Long story short I got a B+ I’m quite happy because I improved a lot since the last grade back in July.

So now I can go to the next level (Advanced 2), which starts in January. I just need to keep on working

With that said the only thing left is to wish you a Happy Christmas. I know I haven’t been blogging lately, hopefully 2012 will bring interesting stuff to share.

Anyways, enjoy the holidays with friends or family.

All best,

Rick

How to change opacity with jQuery fadeTo

Rick — Wed, 23 Nov 2011 09:00:31 +0000

I already showed you How to change opacity with jQuery.

In my previous post I used the attribute opacity.

Today we will do the same with the jQuery function fadeTo.

$(document).ready(function(){
$("img").hover(function(){
$(this).fadeTo("slow", 1.0);
},function(){
$(this).fadeTo("slow", 0.6);
});
});

Smooth Scroll Effect to anchor – jQuery

Rick — Tue, 22 Nov 2011 07:39:21 +0000

Add a smooth scroll effect to an anchor with this simple jQuery snippet.

You need to define a link and then an item with the anchor ID.

In the example below it uses a class to identify the link. You could remove it or change it to your needs.

<h1 id="anchor">Lorem Ipsum</h1>

<a href="#anchor" class="topLink">Back to Top</a>

$(document).ready(function() {

$("a.topLink").click(function() {
$("html, body").animate({
scrollTop: $($(this).attr("href")).offset().top + "px"
}, {
duration: 500,
easing: "swing"
});
return false;
});

});

Found it here.

Optimize MySQL turning Off InnoDB

Rick — Wed, 26 Oct 2011 07:40:26 +0000

If your MySQL databases uses MyISAM instead of InnoDB you should turn the last one Off.

It should free memory and optimize your MySQL performance.

I just did it on my VPS after that the mysql process (using top command) uses less memory.

Edit my.cnf

pico /etc/mysql/my.cnf

Add the following line

skip-innodb

Restart MySQL

/etc/init.d/mysql restart

How to Delete all E-mails from SSH

Rick — Tue, 25 Oct 2011 21:17:40 +0000

I’ve been struggling with the e-mails in the new VPS for the past few days. I’m not done yet but I’ve learned a couple of things…

Delete E-mails

Where my_user is the name of the user.

> /var/mail/my_user

Read those e-mails

A nice way of reading the e-mails is using the less command.

less /var/mail/my_user

if(is_array($user->roles)){

if(in_array('administrator', $user->roles)) return home_url('/wp-admin/');

Boost your server performance with APC for PHP.

The default settings are usually fine but you might want to look at advanced configuration (here).

Pro Tip: if you have WordPress and W3 Total Cache installed you can setup the cache plugin to work with APC. It will indeed improve your caching

Playing around, my first VPS

Rick — Fri, 14 Oct 2011 07:44:54 +0000

Yesterday I purchased a VPS Hosting at Linode.com

So far so good. This VPS is an unmanaged service so you have to do it all by your own.

I never set up a server before but I used the super basic linux commands.

I already installed PHP, Mysql, phpMyAdmin and even a WordPress is running there.

My plan is to move everything from my actual hosting (Siteground) to this cool Linde.

Siteground it’s been a great hosting but I was having some CPU and memory issues in my main blog (quicoto.com). Not enough power I guess

So, if you have any tutorials / blog that can help me with the server administration I’d appreciate it.

Expect to see some linux weird posts around here from now on
