We all use mobile devices every day. Well, at least most of us. All those smartphones, tablets, gadget-watches, etc. Most of us cannot imagine life without these things. Of course, these devices are used a lot to access the Internet. Howerver, not all websites will look the same on different screens. In fact, a lot of websites will look really bad on smaller screens. I'd even say most of web sites!

In the modern web design there is very common dilemma whether to create mobile standalone website, or create responsive design. As usual each option has its pros and cons. In this article I will look at both options and show a sort of comparison.

Wow! Such an interesting thing I just found.

I am quite sure that most of web developers know what the SQL injection is, and nowdays it seems that even junior developers know basics on how to protect web applications against this type of hacker attack. However, I often see web developers underestimate the level of potential threat. Some web developers think: "We are too small to be interesting for hackers", but they forget that security wholes in their applications can be used to attack other resources, systems and users.

In this post I am not going to show how to attack web applications using an SQL injection, but I'd like to show why SQL injection is dangerous and also how to protect against SQL injection.

If you are looking for a method to trim leading and trailing white spaces in all elements of a PHP array, you could use the following code:

<?php
// custom function to trim value
function _trim(&$value) 
{
    $value = trim($value);    
}

$data = array('  a  ',' b',' c   d ');
array_walk($data,"_trim");

var_dump($data);

/*
Output:
array (size=3)
  0 => string 'a' (length=1)
  1 => string 'b' (length=1)
  2 => string 'c   d' (length=5)

*/

This works, but might look a little long. If you want a shorter solution, here it is:

Just a few thoughts...

I cannot remember how many various job interviews I have passed in my professional career. Maybe fifteen, or twenty, or maybe more. Some of them were successful, some of them not. However, very rarely I have met a really good recruitment process. Whether in Eastern Europe or in Canada – I noticed that everywhere.

Sometimes it was just a waste of my time when, for example, the potential employer declared something like: "Actually, we are looking for a specialist with a slightly different skills set" or "Unfortunately, we are limited with our budget and cannot offer you the salary that you are seeking. How about a salary 20% less than you are making now?". Seriously?!! Guys, you were aware about my salary expectations before you asked me to come for the in-person interview!

Keep in mind that for every such interview candidate should make some time to prepare, leave early from the current job (or come in later), and maybe even take a day off. Also, potential employers are spending their time too! So, why should they both waste time if a short phone call may help to figure out whether it makes sense to meet or not?!
