Stop WordPress From Compressing JPEG Images

According to some blogs, WordPress automatically compress your JPEG images to 90% quality, but this information is false.

This only happens on the resized images WordPress creates. The original uploaded image is saved unaltered, as the "full" size.

Anyways, you can stop compressing of JPEG images by putting following code into your functions.php file:

add_filter('jpeg_quality', function($arg){return 100;});
add_filter( 'wp_editor_set_quality', function($arg){return 100;} );

Google: How Fast Is Our Hummingbird


15 years have past since Google Search first appeared on the stage. Back in 1998 the searching process was far from perfection:  the huge machine called computer is on, the user type in keywords into the search system and the system manages to find several websites with the required information. Now it sounds funny, but at that time it was a miracle!

The whole process and the devices have changed since 1998. It is so easy to find billions of websites with one click on a tiny device in your pocket. Search systems are powerful, quick and very convenient. You can even ask the question in a loud voice and your inquiry will be satisfied. What else can be done here? Are there possible improvements? Google proves that there is always space for making changes and striving for better result.

New search algorithm from Google has got a beautiful name of a small but smart bird – the Hummingbird. It was presented on the press-conference dedicated to the 15th anniversary of Google.   The name for the new offspring was chosen in order to emphasize the accuracy and high speed of its work. The company said that changes in the search engine had been made a month ago and covered 90% of search queries, but the notification on the transition to the new search algorithm Hummingbird was decided to give on the 15th anniversary of Google. The press conference took place in the garage, where 15 years ago Sergey Brin and Larry Page had started a glorious history of  the search giant.

Amit Singhal, the head of Google's core ranking team, says that the current updated search algorithm is perhaps the most radical since 2001, the year he began to work in the company. Last major update search engine Caffeine was aimed primarily at increasing the speed of information indexing rather than the processing of the collected information. Hummingbird handles requests not only for keywords, but also according to their meaning. Thanks to this function, the inquiries made by users can be longer and more complex.

As the nature of inquiries has changed recently, the need to improve search algorithm appears. Earlier search inquiries were made in the form of short phrases with a large number of keywords. Today a user can make up search inquiries with the help of colloquial phrases, sometimes quite long and complex. The second reason, which made ​​it necessary to use a new search algorithm is the development of voice search. The time offers new standards, gadgets and approaches for search systems, that is why now is the right time for changes.

Tamar Yehoshua, vice president of the research department, demonstrated the abilities of new search algorithm to understand the associated inquiries. She offers Google to open photos of the Eiffel Tower, and immediately afterwards, without specifying what exactly she is talking about, asks questions: "What is its height?", "When was it built?", "Show me the photos of the building process". Next she presented the way voice search Google works offering to find information about the Impressionist painters.

Unfortunately, there is no way to compare the results of search system efficiency "before" and "after" the introduction of the new search algorithm. However, Google gives a few examples. For instance, request «acid reflux prescription» (acid reflux recipe) used to offer a list of medications that may be useless for users who sought for general information on the treatment and general information about the necessity to take medicine. The new algorithm offers the article containing this exact information.

Is it possible that the new search algorithm from Google made the search system worse? Hummingbird creators are sure that is unlikely, saying that they can’t approve that search system is better now, still, there are no evidences of dissatisfaction on the part of users. As everybody knows, people complain when they notice errors but they rarely see improvements.

Time will show how fast and smart Hummingbird is. A month after its start new algorithm justifies our hopes.

    $authors = $wpdb->get_results("SELECT user_nicename AS nicename from $wpdb->users");   
    foreach($authors as $author) {
        $author_rewrite["({$author->nicename})/page/?([0-9]+)/?$"] = 'index.php?author_name=$matches[1]&paged=$matches[2]';
        $author_rewrite["({$author->nicename})/?$"] = 'index.php?author_name=$matches[1]';
    }  
    return $author_rewrite;
}

// The second part //
add_filter('author_link', 'no_author_base', 1000, 2);
function no_author_base($link, $author_id) {
    $link_base = trailingslashit(get_option('home'));

How To Login To WordPress Using Your Username Or Email Address

By default, WordPress only allows us to login to WordPress powered sites only with our username. But most of us prefer to enter our email address to login because remembering your email is more simple than usernames.

Add Short URL Below Posts In WordPress Without Plugins


Previously I shared a post on this blog about adding a Short Link Widget Below Posts In Blogger, which is a great tutorial for Blogger admins. But I never shared anything like that for WordPress blogs. There are a lot of plugins to add this short link widget below your posts, but we're going to do this without any crappy plugin.

Plus, instead of going with one short link service, you can choose between two short links services. Both services are well known, and easy to use. These two short links services are tr.im and TinyURL.

Add Short URL Below Posts In WordPress:

Add one of the following two codes to your functions.php file:

For tr.im:

function getTrimUrl($url) { $tinyurl = file_get_contents("http://api.tr.im/api/trim_simple?url=".$url); return $tinyurl; }

For TinyURL:

function getTinyUrl($url) { $tinyurl = file_get_contents("http://tinyurl.com/api-create.php?url=".$url); return $tinyurl; }

After adding one of the above codes to your functions.php file, add following code in your single.php file, within the loop:

<?php $turl = getTinyUrl(get_permalink($post->ID)); echo 'Tiny Url for this post: <a href="'.$turl.'">'.$turl.'</a>' ?>

Above code is for a hyperlink style short link. You can also add a text box style widget with the following code:

<?php $turl = getTinyUrl(get_permalink($post->ID)); echo 'Tiny Url for this post: <input readonly="true" type="text" value="'.$turl.'"/>' ?>

Save your files, and That's IT!

5 Professions For Being A Good Blogger


Before moving to very specific nuances of blogging every new person in this field of Internet acting should consider certain basic things. We are talking about that skills which are greatly required for a successful blogging career. These five professions are truly advised to master for a proficient blogger.

Profession #1 A Writer:

The ability to compose a text is the most important skil for any blogger. Even if you have a photo blog, you still have to write a title and subheadings in a correct way.

Advice: There is no need to know how to write compositions on a certain topic. to know how to write advertising texts is a more important skill!

How to become a skillful writer? There is only one possible answer! You simply need to write. Yes, it will be extremely difficult at the beginning but in time you will learn how to express thoughts and feeling “on the paper.” Classic book on how to write advertising texts can be rather helpful for a new writer. For example, it will help you with an advice on how to pick headings for articles. You can also read heading of teaser advertisings to see the way genius copywriters work.  

Profession #2 A Proofreader:

Of course, you need to write without any sort of mistakes. Sometimes misprints happen with everyone, still if you are the author of a misprint it’s you who will feel embarrassed for it! It’s of vital importance not to make mistakes. 

How to become a good proofreader? The only way out here is to read without stopping. Reading classic literature works helps a lot. Why should you choose classic literature for reading? Anyone will agree that literature of the past is reach with beautiful expressions and good grammar. At the same time not every novel by modern writer is of the same literature quality as classic work.  At the moment we themselves are working on our writing quality.

Profession #3 Marketing Specialist:

To be more specific you need to become a professional Internet marketer. It’s highly recommended to have at least basic knowledge on SEO and SMM. You can use another ways of blog advertising, like writing the website on the pavements, why not? However if you choose more traditional ways of website promotion you’d better get to know more about SEO and SMM.

Profession #4 A Programmer

To make a blog using Blog hosting services doesn’t require specific skills except of browsing. In case you have a desire to create your own blog you will have to learn how to use HTML and PHP as both of them are to be useful rather frequently.  

Profession #5 You Choose:

If you are not going to write posts on such topics as “I woke up. Today is a nice weather” you need to decide on a topic of your blog. Obviously, you have to be a professional in everything concerning the topic you choose. In other words another profession is to be mastered!

How To Change WordPress From Name And Email Address

In many actions, such as registration, password request, plugins and more, WordPress sends email to your users and readers. The default sender name is "WordPress" and the default sender email address is wordpress@yoursite.com.

If you're working on a client site, then I guess he wouldn't like WordPress' default sender name and address. However, it's extremely easy to change the default values to your custom ones. Most of us tries to look for the settings in WordPress' wp-mail.php file, but it's not there.

There settings are written in WordPress' pluggable.php file (wp-includes / pluggable.php). Find following code in line #317- #337 of your pluggable.php file:

// From email and name
// If we don't have a name from the input headers
if ( !isset( $from_name ) )
    $from_name = 'WordPress';

/* If we don't have an email from the input headers default to wordpress@$sitename
 * Some hosts will block outgoing mail from this address if it doesn't exist but
 * there's no easy alternative. Defaulting to admin_email might appear to be another
 * option but some hosts may refuse to relay mail from an unknown domain. See
 * http://trac.wordpress.org/ticket/5007.
 */

if ( !isset( $from_email ) ) {
    // Get the site domain and get rid of www.
    $sitename = strtolower( $_SERVER['SERVER_NAME'] );
    if ( substr( $sitename, 0, 4 ) == 'www.' ) {
        $sitename = substr( $sitename, 4 );
    }

    $from_email = 'wordpress@' . $sitename;
}

First red colored WordPress in above php code is your "sender name", while second red colored wordpress is the username of your email address. Just change there values with your custom ones and save the file.

How To Disable HTML In WordPress Comments



I really hate spammers. They make me sick with their spam comments with all the bold text and hyperlinks. I know that I'm not the only one with this crappy problem, since spammers are everywhere these days. Some of them should write a book about "The life of a Spammer."

You can easily disable HTML in WordPress Comments.So if someone uses the strong code, it will not bold the text etc. It's really important for a WordPresser to disable HTML comments to prevent spammers from commenting with HTML formatted comments.

Just add following code in your functions.php file:

// This will occur when the comment is posted
function plc_comment_post( $incoming_comment ) {

// convert everything in a comment to display literally
$incoming_comment['comment_content'] = htmlspecialchars($incoming_comment['comment_content']);

// the one exception is single quotes, which cannot be #039; because WordPress marks it as spam
$incoming_comment['comment_content'] = str_replace( "'", '&apos;', $incoming_comment['comment_content'] );

return( $incoming_comment );
}

// This will occur before a comment is displayed
function plc_comment_display( $comment_to_display ) {

// Put the single quotes back in
$comment_to_display = str_replace( '&apos;', "'", $comment_to_display );

return $comment_to_display;


That's IT!

Prevent Image Hotlinking With .htaccess

Image courtesy of markinns.com
Ever wonder how someone stealing your images, directly taking the URL and display on their own website can effect your bandwidths? This is what we call image hotlinking. With every single view of our images on their site cost us bandwidths. Because it's called directly from our server.

Not sure about you, but I paid for this bandwidths (not for this site). Just like almost everything, there is a way to stop thieves  from stealing our bandwidths without our permission. For those who are wondering, this tutorial is also for WordPressers.

Visit your FTP/File Manager and add following to your .htaccess file:

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yourdomain.com [NC]

Hide Dashboard Login Errors In WordPress

In this tutorial, I'm going to show how you can easily hide login errors in WordPress. It's a great way to protect from WordPress from hackers. Whenever you login with the correct username but with the wrong password, a message appears saying "Error: Incorrect Password." WordPress has now given a clue to hacker that the username entered is in the system, and that they simply need to crack its password.

Similarly, an "Error: Invalid username" also appears when you enter an unavailable username. It's better for you to prevent hacking by hiding this error message. In order to keep this from happening, you need to add this code to your functions.php file:

add_filter('login_errors', create_function('$a', "return null;"));

This filter code will remove error message from the login page. The error box will still appear, but without any text.

How To Automatically Empty Trash In WordPress

The Trash feature was introduced in WordPress 2.7, and since then, if you click "Trash" for any item, it will be sent to the trash. It works similar to the Recycling Bin feature on Windows. By default, the content you trash remains there for 30 days before being permanently deleted. However, you can also delete items from the Trash at any time.

You can also modify the 30 day period with some simple codes. Just add this line to wp-config.php and you’re done:

define('EMPTY_TRASH_DAYS', 5 ); // Empty trash every 5 days
