Prestashop + Symfony

I have not been blogging for quite long time (three years ) and now again started to blog and share my thought and experience with like minded people.

I am happy to write my first post after long time about Symfony and Prestashop. When I heard that Prestashop introduced Symfony into their application I was really happy to hear that because it definitely boost Prestashop. I know this because I have many years experience with Symfony as well as Prestashop, even these days on daily basis I work with Prestashop and Magento.

Here I don’t want to compare Prestashop with Magneto (I will do in another post) but I can tell you from my experience that Prestashop is lacking from good robust infrastructure such as Symfony.

Why Prestashop is good with Symfony? I will answer in coming post but before this just to let you know that for now, Prestashop used Symfony in some parts of application not 100%, only in back-office although there is a plan to slowly use in front-office too.

I know some developers will disagree with this Prestashop’s move but trust me it worth it. These developers who are not familiar with Symfony they must learn a bit, so my advice to these developer is, wait, just learn what’s Symfony.

Since this is my first post after long time, I will keep it short. I will explain the benefit of Symfony in Prestashop later. Feel free to comment, always happy to hear from you.

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…

Laptop touchpad issue on Linux

I installed Linux (Ubuntu 16.4 LTS) on my new laptop, Fujitsu E series, all went well apart from touchpad which did not work at all. I spend few hours searching (AKA Googling) but could not find any hope. That was embarrassing for me who called himself professional Linux user but cannot fix touchpad issue, what about typical Linux user? there must be way, so I kept searching and reading until finally I found the fix and all is working now. Here is the fix if anyone has similar issue:

In cammed line, run:
sudo modprobe -r psmouse

It should work fine for now but only for current session, it may not work after restarting your laptop, so to add permanent fix, do:sudo vim /etc/modprobe.d/psmouse.conf

And add following, then save and exit.

options psmouse proto=imps


I used vim, you can use your favourite text editor such as gedit, vi etc. I hope this helps someone and save their time. Read more on modprobe.


Thank you for reading this, as always happy to hear from you.
