Facebook Took Action to Block Developer Tools - Know Why

If you recently tried accessing the developer tools in your browser on Facebook you might have noticed a large notification in the console highlighted in red. Well, that's for a reason, if you haven seen that scam/spam yet let's tell you more about it.

Developer Tools are great for debugging websites and running scripts manually on a web page, it could be done on any website including Facebook. By writing a script, the author can make anything do with the site on Facebook they can use it for sending friend requests, making comments etc. anything that is possible. Because all that functions are controlled by JavaScript onsite.



Taking advantage of these awesome feature of a browser, some notorious spammers have wrote a script which auto-tags people and like pages associated with them on their statuses where they post instruction to use their code they wrote by claiming that the user will get a new theme for their Facebook, which would seem to work but what it does in the background will terrify you.

The code would send unwanted likes to the pages the spammers wants, it will auto-tag your friends in 100s of status automated by the script and much more as they might even get access to your account. The spam have got amazingly viral as people do really think it's going to work and try it without giving it a thought.

How does it actually look ?

This is an example of well planned viral spam by some script kiddies originating probably from Indonesia.

The link they tell you to open contains the code which they ask you to run in the browser's console which then do what it is supposed to - screw you.

If you see any such things in the future don't let it make you look like a fool! Just block that person and you are good and safe.

Facebook Took An Action to Control it

By disabling developer tools temporarily. Developer Tools is a great tool for developers so they didn't disabled it permanently on their site, but it let's you choose what you want to do. And will also show you what could be the consequences of running scripts from Unknown sources.

Not all scripts are dangerous, for example see my "How to Select All Friends at Once on FB" script, it just automatically selects your friends for inviting them in events etc. But you can clearly understand from this that code can do things that you don't expect to be automated.

Beware before you run scripts from third-party sources especially from these so-called lucrative offers. And even though the script seems fine to you make sure to see what others say about it, what's their opinion to get an idea about it.

It's all, be safe online :) 

Making Images Fit in Post Body on Blogger

If you are working on a responsive design for your Blogger blog, or you are just tired of resizing your images in post editor to fit in the post container then this tutorial will show you an easy way to make images fit with it's surrounding.

This problem occurs often when you try to post images of the dimension larger than your content area or you are just using a responsive layout and when it down-sizes, the images overflows the content area.

Before you continue with the tutorial, check the demo:
Demo: Without the CSS Demo: With the CSS

In the first demo, the image in the container overflows because the width of the image is larger than that of the image, but in the second demo, if the image width is greater than the container's, it will fit itself to the container.

The Code!

All this can be achieved with a small block of CSS code. Before I start giving you lectures on how this works, here's the code for you to use (can be used in most Blogger Templates, but you might need to change the selectors if you are using a custom designed template):

.post-body img {
    max-width:100%;
    max-height:auto;
}

Now you just need to apply this code to your blog, check this tutorial to learn how add CSS in Blogger.

How does it work?

If you are not a web designer or coder, then this might all seem like a magical charm to you, but it's just code, code that's made to make your life easier. Well, so if you are ready to get bored then I am starting my chapter on CSS.

What actually does the magic is the max-width CSS property which gives any element a maximum width limit. So if you specify an element the the maximum width of 200px, it wouldn't exceed it. The 100% value tells the browser that the element(s) must not exceed the full content width of the container.

The max-height property helps in keeping the original proportion of the image intact. To know more about what would happen if you specify a value in percentage then try and check the results ;)

Changes to Files not Immediately Applied on WordPress Blog

A few days ago I got a project to setup a WordPress blog on the client's website. Most of my work included editing and adding codes to re-design the look of the blog, so editing, saving and viewing is a normal process. But I found a issue of changes not updating on site immediately after I updated the files.

I have worked on WordPress many times, but this project required me to work in a different environment, by different environment I mean editing theme and other PHP files only through the WordPress interface and the Web Host was Yahoo which still provides a quite older version of WordPress for their customers.

As the primary job was designing the blog I had to edit and reload the blog page to see the changes on the live blog. Many times the changes didn't appear immediately on the blog, especially the header.php and other page template files.

While I was working on it, I didn't had much problem because of this issue but when the client tried checking the changes I made they complained about the blog not updating. I thought it was a problem with the web host but the actually cause of the problem turned out to be something else.

WP-Cache is what causing the problem

I didn't even think about it. I knew there were cache plugins for WordPress but my mind never focused on it. After exchanging messages with the client he sent me a link to a forum where the cause of the problem was mentioned and it was WP-Cache plugin.

Fixing it is easier than you may expect, just login to your WordPress Dashboard -> Settings -> WP-Cache

When you are in the settings page for WP-Cache plugin, click the "Disable it" button to disable the plugin.

Once you disable the plugin, any changes you make to your WordPress files will be immediately applied to the live site. That's a good idea when you are working on a re-design and you need to preview your changes again and again.

If it's not WP-cache..

If you don't have WP-cache plugin for your site then something else or other cache plugin is causing the problem. Look for other cache plugin for your WordPress blog, you will find all your plugins in the Plugins tab. If you find one then just disable it to solve the problem.

If it's not even a plugin then you might need more help with your blog's technical details, so it's a good idea to try WordPress Support Forum.

Hiding Newer - Older Post Links Below Posts in Blogger

The older - new post links or blog pager links are one of the most basic part of a blog. It provides an easy access to other blog posts on the blog. If you want to remove it then continue reading the tutorial.

In this short tutorial you will learn how to control the display of the three links below each posts called Blog pager (Newer - Older Post and Home link).

There can be many reasons you want the the Newer - Older post links to be removed from your blog. One can be that you are using your blog for just a single paged blog and in that case any blog pager links are not necessary.

Hiding it with CSS

The blog pager has three links Newer Post, Home and Older Post, if you want to remove only a specific link(s) I have provided the code for that too. Let's start with the code to hide the all the three links.

To learn how to add the CSS codes in your template, see this tutorial:
How to add CSS to Blogger

Hiding All Three Links

Hiding elements on web pages is not a rocket science, all you need is a small snippet of code. To hide the pager links we need this a one line CSS code

#blog-pager {display:none;}

Hide the 'Newer Post' link

To hide just the "Newer Post" link in the blog pager use the following CSS code

#blog-pager-newer-link {display:none;}

Hide the 'Home' link

Using this code will hide the Home link in the blog pager

#blog-pager .home-link {display:none;}

Hide the 'Old Post' link

And use this for hiding the "Older Post" link

#blog-pager-older-link {display:none;}

A little note..

Using CSS to hide these links wouldn't remove the links from the HTML document but it will simply hide it from view, this is easier than and safer than removing it from the root. But if you still want to entirely remove it then try this

Encrypt Your Personal Details with JavaScript

When you have a lot of online accounts to handle and don't have enough time to memorize all the passwords it becomes an annoying problem. What if you could save your passwords and other details in a simple text file on your PC ?

That makes sense but if your PC is accessible to others it is not a good idea to explicitly save your personal account details in a text file available to every user on your PC.

There are many other ways to keep your account credentials safe on your computer but they are often a folder password software or something like that, but it is a waste of time and most of the times those software are malware itself.

Another option is using an encryption/decryption software on your PC but you won't be able to decrypt your details if you don't have that particular software on the other PC too. Say you downloaded the encrypted file from your Dropbox on a public PC, now to decrypt it you need to install an extra software on it, and it's not a good idea though.  

Let's Start Encrypting/Decrypting

There's an inbuilt encode and decode function in JavaScript that takes in an string and output the result. The function we are talking about are btoa and atob, in JavaScript these functions are generally used for transmission of data that may cause communication problems.

But I found another use of these functions and when I found myself saving my account details on my PC accessible to anyone. I then used those function to encode the details, save it in a text file and when I needed it I used the decode function.

Open the JavaScript Console

First we need to open the Developer Tools with JS Console in the browser. If you want to learn how to open developer tools in different browser check this tutorial.
http://www.stramaxon.com/2013/10/developer-tools-in-browser.html

If you don't want to read that tutorial then just use these keyboard shortcuts to open JavaScript console on your browser :
Chrome - CTRL+SHIFT+J (CMD+SHIFT+J on Mac)
Mozilla Firefox - CTRL+SHIFT+K

Encode it first

Finally when we have the Console open, we are ready to use it for encoding any text we like. The function that encodes any text is btoa("Text you want to encode") if you run this in your Console it will output this VGV4dCB5b3Ugd2FudCB0byBlbmNvZGU= .

We now know what the function does now see how can you use it

btoa("Something here");

The text between the parentheses and double quotes is the text you are encoding so replace it with your personal details you want to encode and once you run it the console will return the encoded version of it, now you can save that text in your file and no one be able to read it (if you don't have any geek or programmer kind of people near you, can be worry free).

Here's a screenshot

Time to Decode

Encoding is of no use if you can't decode it for later use. As btoa() encodes a string similarly atob() decodes the encoded text.

Try running this code in your open JavaScript Console

atob("VGV4dCB5b3Ugd2FudCB0byBlbmNvZGU=");

This will output "Text you want to encode". You use this function in the same way but you just need to pass encoded data in the parentheses.

Tip: If you want extra protection, you can encoded the encoded data too but you also need to decode it the times you encoded it.

Bonus Tool!

Even before writing this article I had written a small JavaScript tool you can use to encode/decode data without worrying about the Console and function codes. Click the link below and start using it.

Sometimes it's fun to to a work in the difficult way ;)
