resize an image function
Posted on | July 2, 2009 | No Comments
I wrote this function long time ago and I have used it so many since then. I decided to publish it.
You can find plenty of similar functions but this one is a little bit different. As a parameter you specify new MAX dimensions so image will be scaled based on its height or width. I believe I have enough comments in the code.

“Cytrynowka” Polish Lemon Vodka
Posted on | May 18, 2009 | No Comments
I was supposed to write about web development but recently I found my old recipe on how to make your own ‘cytrynowka’. All you need is:
- 1L 190 proof alcohol (I use EVERCLEAR 190 PROOF GRAIN ALCOHOL)
- 8-10 lemons (depends on size)
- 1.5 glass of sugar
- little bit of salt
- 1L of water
- Ok so to start you have to wash lemons and cut off the ends (and throw them away). Cut all lemons into the pieces (about 1/4 - 1/2 inch in size).
- Put lemon pieces into the metal bowl or pot, add sugar, salt and one glass of water. Squeeze the lemons very well and leave like that for about 2 hours (don’t forget because it will become bitter if you keep it to long)
- soak and remove lemon pieces, filter everything (use gauze pads to filter out even the smallest pieces of lemon). Add 3 glasses of water
- in about 2-3 days filter everything again
- 5 days later it is ready to drink 
best served chilled in shot glasses
enjoy

“COMPETITIVE SALARY”
Most of our competitors don’t pay much either.
“JOIN OUR FAST-PACED COMPANY”
We have no time to train you.
“CASUAL WORK ATMOSPHERE”
You’ll be here very late, very often — might as well be comfortable.
“MUST BE DEADLINE-ORIENTED”
Your first four projects are already way overdue.
“SOME OVERTIME REQUIRED”
Did we mention that you’ll be here very late, very often? And most weekends.
“DUTIES WILL VARY”
Anyone in the office can boss you around.
“MUST HAVE AN EYE FOR DETAIL”
We have no quality control.
“CAREER-MINDED”
Female applicants must be childless.
“APPLY IN PERSON”
If you’re old, fat or ugly, that position has already been filled.
“NO PHONE CALLS PLEASE”
This job listing is just a legal formality. The position was filled by some executive’s nephew.
“SEEKING CANDIDATES WITH A WIDE VARIETY OF EXPERIENCE”
Due to consolidation, you’ll be replacing three people.
“PROBLEM-SOLVING SKILLS A MUST”
This company is a total mess.
“REQUIRES TEAM LEADERSHIP SKILLS”
You’ll have all the responsibilities of upper management, without the pay, title or respect.
“GOOD COMMUNICATION SKILLS”
Listen to management, figure out what they want, don’t ask too many questions and get the sh*t done.
Why should you use jQuery
Posted on | September 3, 2008 | No Comments
If you ask me one year ago “have you seen jQuery” my answer would be “have you seen what?”
If you ask me six months ago I would say “I heard about it but I don’t see any benefit in using it. I know javascript well enough to write my own code”.
And I was sooooo WRONG.
I just finished small project for my friend www.jardinsdesreves.pl and I decided to give it a try.
The benefit: my js file is only 170 lines long.
I just want to show you couple benefits of this wonderfull framework.
FORMS:
I have never seen a simpler way to submit forms via ajax.
Just look at the simple example:
1 2 3 4 5 6 7 | <form> <input type="hidden" name="id" value="2"> <input type="hidden" name="save" value="1"> Title: <input type="text" name="form_title"><br> Content: <textarea name="form_content" cols="25" rows="8"></textarea> <input type="button" value="Save changes" onclick="sendForm('text_save.php');"> </form> |
1 2 3 4 5 6 7 8 9 10 | function sendForm(post_url) { var request = $("form").serialize(); $.post(post_url, request, function(data) { formResponse(data); }); } function formResponse(resp_data) { $("#message").text(resp_data); } |
As you can see jQuery does all job for us.
There is only one requirement - each form element needs to have a name (not id).
serialize() function does great job and will post all form to ‘text_save.php’ where we can do processing and show response to the user.
In the next article I will show you how to use great jQuery plugin ‘ajaxfileupload.js’ to upload files.

This is just a beginning.
I hope to find enough time to write some articles about web development (PHP, Javascript, CSS, Flex …) and my hobby photography.
I spend a lot of time writing code and even more time googling around for help and solutions. I know how difficult it is to find something useful. That’s why on my blog I will post only useful information and I will try not to copy anything that is already posted on other blogs.
Don’t expect to find a new post every day but if you have any questions or comments to my articles I will respond ASAP
Lets get started
