Take Full Page Screenshot in FireFox with No Addons like a Boss

by

I just discovered this awesome technique of taking full page screenshot of any webpage of any Width and Height (regardless of your display screen size) using Firefox in Mobile View or Responsive Design Mode (official name).

Here is how to do it:

  1. Open the URL of the webpage you want take screenshot
  2. Turn on Mobile View or Responsive Design Mode (by pressing Ctrl + Shift + M)
  3. Edit the Width and Heights to your desired dimensions , just double click the area (highlighted and numbered-1 in screenshot below) where it lists current width and height and enter your own, and then click somewhere on the page to let it take effect.
  4. You are ready, hit the Screenshot/Camera Button (highlighted as #2 in screenshot below) and you will have your screenshot ready to be downloaded or automatically downloaded to your downloads.

My Calculator is Now NodeJs instead of Google or Excel

by

Wow funny thing I noticed today that I have been using NodeJS, in terminal for doing my calculations and arithmetic operations. Then I realized how I have always been using different methods and tools on my laptop to perform quick arithmetic calculations.

NodeJs is My Handy Calculator

At start it was usual system calculator. Then I started to use Spreadsheet most of the time for performing calculations when I learned basic maths operations and functions available in spreadsheets. After sometime Google, became my favorite calculator for fast arithmetic operations.

Just recently on my Ubuntu system I caught NodeJs fever and have been playing with any NMP package I could find and play with on Javascript. And wow the new use case which I found today was that, I have been using Node in my terminal for performing quick calculations. I am posting it to share with the world so if you find doing your calculations using something other than conventional or system calculator, don’t panic, it is normal 😀

SASS & SCSS to Super Charge CSS Skills

by

CSS is becoming complex day by day and as projects become bigger so gets the stylesheet and its CSS styles. To manage and keep track of your CSS stylesheets is not that easy as it used to be in the early days.

CSS preprocessors are here to rescue and SASS (with new syntax SCSS called Sassy CSS easy to follow for CSS users). I have tried many times to go with CSS preprocessors like LESS or SASS but have not been able to stick to it as my projects were not that complex or I did not need to add more tools into my workflow. But recent weeks I have been using SASS and I am finding it so useful and it is here to rescue me for bigger and long term projects to help me manage and keep track of CSS stuff.

Here is good tutorial to follow if you are new to SASS and want to give it a try:

http://code.tutsplus.com/tutorials/a-wordpress-development-process-using-sass-and-compass–cms-21861

On Ubuntu it was easy to get started by just adding RUBY with RVM. Following tutorial by Ryan Bigg at his blog at this blog post: http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/

Enjoy your adventure with Ruby installation challenges , and SASSing your CSS 🙂

Bluefish Editor – Text Editor for Programmers

by

I am loving the Bluefish Editor, it is like just a Lightweight IDE. I am learning about it and will keep this post to keep track of interesting things I learn about it and add to my WorkFlow. Currently I am using Ubuntu 14.04 with Bluefish Editor and Firefox autoreload extenstion. It is really helpful work flow for faster development.

Most useful thing of Bluefish editor is shortcut:Ctrl+Shift+Enter after Entering some html element tag first letter like e.g. p (then hit above shortcut key, and you will have

 

with cursor at right position to get started to write in it.)

It can even extend p.myclass to <p class=”myclass”></p> and p#myid to related syntax. For quick great tutorial about this. Check out this URL:

http://www.troubleshooters.com/linux/bluefish/

Short cuts to browse files in Bluefish Editor:

  1. Alt + 1 to first tab, and so on
  2. To move between multiple windows Unity shortcut for Ubuntu is : Alt + ` (just the key above your TAB key)
  3. more to come

Other Bluefish Editor Settings:

  • Changed Dir Base to www folder in sidebar panel.. by right clicking on any (www folder in my case) and then selecting “Set as Base Dir”

FireFox Responsive Web Design View RWD

by

My younger brother, also a programmer 🙂 , shared with me this little nifty keyboard short-cut  and introduced to Mozilla Firefox’s awesome Responsive Design View. I am happy to share it with my readers and for my future reference.

In the past I had to use plug-ins, or resize window manually. But Firefox has made it so simple and so great.

1. Keyboard shortcut is : Ctrl + Shift + M  (when you are on FireFox)

2. And Your Firefox will tranform itself to awesome responsive design viewer, you can check different views and enjoy.

Also it really helps to test bigger screens sizes even on smaller screens. It really helps the developer to create responsive web design from their own laptop and quickly check the different screen views without needing any manual window resizing or third party sluggish plugins.

See my site in different views in below screenshots:

Keep Height of Second Div column same as First Div

by

Hi,

In responsive web design, I often encounter this issue, and solve it with jQuery. However this time, it was little different took much time to get it right.. So i am posting here for future reference:

<code>

<script>
jQuery(document).ready(function($){
var currentHeight = 0;

$(window).load(function() {
currentHeight = $('#slider').outerHeight();
$('#slider-right').css({'height':currentHeight});
});

$(window).resize(function() {
currentHeight = $('#slider').outerHeight();
$('#slider-right').css({'height':currentHeight});
$(window).trigger('resize');
});

});
</script>
</code>

I had two column layout, with responsive slider at the left, and a div in the right.

As slider keeps changing its height, right div looked bad. So using above code, we can use Jquery which does:

1. Take size of slider (on load as real property in css is not set, and you need to let the page rendered to get the rendered height)

2. Now we have two functions, one changes the height of right div on first page load. And second does the same thing but on every time when window resizes… to keep the height same on every window resize/reload.

Using PTCL & WordPress – Two Unusual Issues I Faced Today

by

Now I would say GOOGLE & GoTrusted VPN rescued me.

Issue #1: Client Site will not Open at PTCL My ISP
A very loyal client of mine, who outsources all programming of her business to me, was having issues with order checkouts. I needed to look into this and fix it asap.

I could see that site was working fine as using proxy I could see it working fine. Problem was that I could not login to it and do the job as public proxies are unsafe…

I skyped my younger brother, Ismail, that can he open this site in his pc in office. He replied that site was not opening there too as they too were using PTCL. I told him my situation… he said why not use VPN and get rid of PTCL stuff. WOW, even I have paid membership with VPN for clients’ youtube work (as Youtube is banned in Pakistan). I fired VPN and there I was able to access the site and figure the issues.

Issue #2: WordPress Gives 404 Error to 1ShoppingCart Thankyou Page return
Buyers of my client reported that after successful payment and order they are being redirected to NOT FOUND 404 page. My client was really upset that what could be the issue…

I double checked all the links, thank you page urls, and settings. Everything looked fine.

Then I did a test purchase and got same error as others 404 on actual URL. I could see the issue,
as there were GET POST data variables being sent by 1ShoppingCart which had conflicting variable name with WordPress’s builtin reserved names.

Next job was to compare all the reserved variables by WordPress and POST variables sent by 1SC, I was able to find both lists, quite long lists. Next goal was to compare and find exact matches.. I used my newly learned Linux ninja skills of text processing through bash. And was able to find the three possible matches and one of them was exact and that was ‘name’ variable!!!

Job was almost done, as next task was to ask WordPress let 1SC send ‘name’ variable and please do not mess with it. Simple solution was to unset the variable which I did by adding simple php unset code in WP-config file. And it solved the problem instantly!!!

For future reference, I will be posting the code and varaibles of both WP & 1SC in the PS of this post.

Thank you,
Mohsin

Giving Access to Specific Bucket in AWS using IAM

by

Hi,

If you are using Amazon S3 for storage, I recommend using IAM to create users with specific access to S3 only or to some specific bucket only. It is great way to give to your developer or client or partner access to specific bucket in your S3 without allowing access to whole Amazon or AWS or S3 account.

Using IAM service in AWS, you can create groups and users with specific permissions. In my case:

  1. I created a group called: test
  2. then added: testuser as a user in the group
  3. Used following policy for the group to give access to only ‘test’ bucket

Policy Code for Specific Bucket View/Download/Upload/Delete Access:
Enable AWS Management Console access to an Amazon S3 bucket:
[code language=”css”]{
"Statement": [
{
"Effect": "Allow",
"Action": ["s3:GetBucketLocation", "s3:ListAllMyBuckets"],
"Resource": "arn:aws:s3:::*"
},
{
"Effect": "Allow",
"Action": ["s3:ListBucket" ],
"Resource": [ "arn:aws:s3:::test"]
},
{
"Effect": "Allow",
"Action": [ "s3:PutObject", "s3:GetObject", "s3:DeleteObject"],
"Resource": [ "arn:aws:s3:::test/*"]
}
]
}[/code]

For Programmatic Access, following IAM policy grants programmatic read-write access to the test bucket:

[code language=”css”] {
"Statement": [
{
"Effect": "Allow",
"Action": ["s3:ListBucket" ],
"Resource": [ "arn:aws:s3:::test"]
},
{
"Effect": "Allow",
"Action": [ "s3:PutObject", "s3:GetObject", "s3:DeleteObject"],
"Resource": [ "arn:aws:s3:::test/*"]
}
]
}[/code]
