PHP Online quiz fail

We had a php test last week and as I am quite good at PHP so I didn’t revise for this test, a few minute before test start, one of my classmates asked me a php question: php-wrong  What can you use to replace like with hate in I like Eminem? I answered preg_replace("/like/", "hate", "I like Eminem") He showed me this website and said you are wrong, I couldn’t believe that I am wrong. Anyway test started surprise! This was one of the questions and I answered the way this website told which later when I checked, it was wrong. I became upset because I didn’t trust my knowledge, if I never knew the answer I wouldn’t be upset because I didn’t have the knowledge. Hope they fix this mistake soon. I made a php quiz online, please report any error you may find.

I solved GCHQ puzzle and this is how I did it

Today, I was reading the BBC news and I stumbled upon this GCHQ puzzle:
Take the digits 1,2,3 up to 9 in numerical order and put either a plus sign or a minus sign or neither between the digits to make a sum that adds up to 100. For example, one way of achieving this is:
1 + 2 + 34 - 5 + 67 - 8 + 9 = 100, which uses six plusses and minuses. What is the fewest number of plusses and minuses you need to do this? I love to challenge myself with these kind of puzzles, so I solved this and here is how:
We have 9 numbers [1 to 9] and also we have three possible separators [+, - and nothing] which to fill the gap between numbers we have 8 combinations of separators, e.g. we have 1+2+3+4+5+6+7-89 which in this case we have six times plus, one minus and one time nothing. 
So, I need to find all possibilities of combination which total is: 6561

Then, hook the possible combinations into numbers and check the total, easy enough. Now print the solution.
I have written this algorithm in PHP but ea…

Why Prestashop needs improvement for large application?

I have worked with Prestashop 1.6 long enough to know inside/outside of the application and even I developed few modules myself, all is simple and great but in small scale. My application is big, I am talking about millions rows in database. Two databases weight almost 18G (see the picture).

One day at 2AM I received a notification that my website/application is down. I looked at the server the application seems OK but the databases gone crazy big, (see the picture) it has gone from 18G to over 90G less than 6 hours. 
Since there was almost none free space left on the server, all server running really slow even I could not restart NGINX. All was frozen. All my websites/applications run on dedicated server on UKFast, so none of websites would work because all is glued together. 
There are many issues here, e.g. the server infrastructure is wrong (I know that already), there should be monitoring service in place which there was no such thing (I know that too) etc. but why this happened,…
