This post is a continuation of the “WordPress Hacks” posts that I wrote earlier.

10 WordPress Hacks to Make your Life Easy
10 WordPress Hacks to Make your Life even Easier

If you liked those, you will love this one. Here goes :-

1. FIGHT CROSS BROWSER COMPATIBILITY THE WORDPRESS WAY

While designing a theme, there are numerous cross browser compatibility issues that raise their head, and most of the times we are left with no choice but revert to using conditional hacks. The following WordPress hacks can really save a lot of headache :-

Open your functions.php file in the theme folder and add the following code :-

1

`2`	`add_filter('body_class','browser_body_class');`

`3`	`function` `browser_body_class($classes) {`

`4`	`global` `$is_lynx,` `$is_gecko,` `$is_IE,` `$is_opera,` `$is_NS4,` `$is_safari,` `$is_chrome,$is_iphone;`

5

`6`	`if($is_lynx)` `$classes[] =` `'lynx';`

`7`	`elseif($is_gecko)` `$classes[] =` `'gecko';`

`8`	`elseif($is_opera)` `$classes[] =` `'opera';`

`9`	`elseif($is_NS4)` `$classes[] =` `'ns4';`

`10`	`elseif($is_safari)` `$classes[] =` `'safari';`

`11`	`elseif($is_chrome)` `$classes[] =` `'chrome';`

`12`	`elseif($is_IE)` `$classes[] =` `'ie';`

`13`	`else` `$classes[] =` `'unknown';`

14

`15`	`if($is_iphone)` `$classes[] =` `'iphone';`

`16`	`return` `$classes;`

17 }

18 ?>

The above function adds the name of the browser (e.g, opera, safari etc.) to your tag like this :-

`1`	`class="home blog logged-in safari">`

Now you being a theme designer can take help of this custom class and write your CSS accordingly if you are facing any compatibility issues with any browser. This can be called as “planning in advance“!

2. SCHEDULE AN EVENT USING WORDPRESS

Many of us already know that posts on a WordPress blog can be scheduled to be posted on future dates. But did you know that this alarm kind of function can be used for different other things too! Here is a practicle usage that lets your WordPress blog shoot out an e-mail to you every hour (A very handy function in case you want to know the uptime of your website – Just make a folder in your e-mail for such e-mails and read them later as log details). Add the following code into the functions.php file of your theme.

`1`	`if` `(!wp_next_scheduled('my_task_hook')) {`

`2`	`wp_schedule_event( time(),` `'hourly',` `'my_task_hook'` `);`

3 }

`4`	`add_action(` `'my_task_hook',` `'my_task_function'` `);`

5

`6`	`function` `my_task_function() {`

`7`	`wp_mail('you@yoursite.com',` `'Automatic email',` `'Hello, this is an automatically scheduled email from WordPress.');`

8 }

You can define your e-mail and subject in the above code yourself.

3. REMOVING UNWANTED LINKS FROM YOUR COMMENTS

Here is a neat function that lets you remove unwanted links from your comments. As before, place the following code in the functions.php file of the theme folder :-

`1`	`function` `plc_comment_post(` `$incoming_comment` `) {`

`2`	`$incoming_comment['comment_content'] = htmlspecialchars($incoming_comment['comment_content']);`

`3`	`$incoming_comment['comment_content'] =` `str_replace(` `"'", ''', $incoming_comment['comment_content'] );`

`4`	`return(` `$incoming_comment` `);`

5 }

6

`7`	`function` `plc_comment_display(` `$comment_to_display` `) {`

`8`	`$comment_to_display` `=` `str_replace(` `''',` `"'",` `$comment_to_display` `);`

`9`	`return` `$comment_to_display;`

10 }

11

`12`	`add_filter('preprocess_comment',` `'plc_comment_post',` `'', 1);`

`13`	`add_filter('comment_text',` `'plc_comment_display',` `'', 1);`

`14`	`add_filter('comment_text_rss',` `'plc_comment_display',` `'', 1);`

`15`	`add_filter('comment_excerpt',` `'plc_comment_display',` `'', 1);`

Spammers Die! Yay!

4. RETRIEVING POSTS WITHIN A DATE RANGE

Sometimes you will need to pull posts between two specific dates from your blog. The code below allows you to do just that :-

1

`2`	`function` `filter_where($where` `=` `'') {`

`3`	`$where` `.=` `" AND post_date >= '2009-03-17' AND post_date <= '2009-05-03'";`

`4`	`return` `$where;`

5 }

`6`	`add_filter('posts_where',` `'filter_where');`

`7`	`query_posts($query_string);`

`8`	`while` `(have_posts()) :`

`9`	`the_post();`

`10`	`the_content();`

`11`	`endwhile;`

12

13 ?>

You can copy and paste the above code anywhere within your template files. Just don’t forget to change the dates.

5. USING MULTIPLE LOOPS WITHOUT DUPLICATION

If you need to break display your posts in different sections (like in Magazine themes), where you want to display a fixed number of posts first, and the remaining later, you can use this code to make multiple loops (with offsetting the fixed posts in the later loop).

The first loop that will pull and display 5 recent posts :-

1

`2`	`query_posts('showposts=5');`

`3`	`$ids` `=` `array();`

`4`	`while` `(have_posts()) : the_post();`

`5`	`$ids[] = get_the_ID();`

`6`	`the_title();`

`7`	`the_content();`

`8`	`endwhile;`

9 ?>

And, the second loop that will exclude the above posts and show the remaining ones :-

1

`2`	`query_posts(array('post__not_in'` `=>` `$ids));`

`3`	`while` `(have_posts()) : the_post();`

`4`	`the_title();`

`5`	`the_content();`

`6`	`endwhile;`

7 ?>

This code basically pulls the post IDs that are not contained in the array $ids[].

6. HIGHLIGHTING SEARCHED KEYWORDS IN SEARCH RESULTS

If you need to highlight the searched text in your search results (which is not an option by default in WordPress), here is the solution that accomplishes this feat :-

Open up your search.php file from the theme folder.
Find the_title() function and replace it with :-

1 mytitle();
Add this code to your functions.php file

1

2 function mytitle() {

3 $mytitle = get_the_title();

4 $keys= explode(" ",$s);

5 $mytitle = preg_replace('/('.implode('|', $keys) .')/iu',

6 '',

7 $mytitle);

8 echo $mytitle;

9 }

10 ?>
Open style.css file and add the following code:-

1 .searched { background: yellow; font-weight:bold; }

We are done. Try searching some text on your blog now!

7. DISPLAY RELATED POSTS WITHOUT A PLUGIN

This is a good hack if you want to show “related posts” below the single post view on your blog without the use of a plugin. Just open the single.php file and paste the following code within the WordPress loop :-

1

`2`	`//for use in the loop, list 5 post titles related to first tag on current post`

`3`	`$backup` `=` `$post;` `// backup the current object`

`4`	`$tags` `= wp_get_post_tags($post->ID);`

`5`	`echo` `"` `Related Posts ";`

`6`	`$tagIDs` `=` `array();`

`7`	`if` `($tags)`

8 {

`9`	`$tagcount` `=` `count($tags);`

`10`	`for` `($i` `= 0;` `$i` `<` `$tagcount;` `$i++) {`

`11`	`$tagIDs[$i] =` `$tags[$i]->term_id;`

12 }

`13`	`$args=array(`

`14`	`'tag__in'` `=>` `$tagIDs,`

`15`	`'post__not_in'` `=>` `array($post->ID),`

`16`	`'showposts'=>5,`

`17`	`'caller_get_posts'=>1`

18 );

`19`	`$my_query` `=` `new` `WP_Query($args);`

`20`	`if(` `$my_query->have_posts() )`

21 {

`22`	`echo` `"` `";`

`23`	`while` `($my_query->have_posts()) :` `$my_query->the_post(); ?>`

`24`	`"" rel="bookmark" title="">`

`25`	`endwhile;`

`26`	`echo` `"";`

27 }

`28`	`}` `else` `echo` `"No related posts were found!";`

`29`	`$post` `=` `$backup;` `// copy it back`

`30`	`wp_reset_query();` `// to use the original query again`

`31`	`echo` `"";`

32 ?>

The above code uses post “Tags” (that you have made in your posts) to relate the posts. So use them wisely!

8. ADD YOUR POSTS TO FACEBOOK

The following hack will add a link within your posts that will allow users to share the post with their friends on Facebook. This can help in bringing extra traffic to your blog. Open the single.php file from your theme folder and paste this code within the loop where you want the link to show up :-

`1`	`"http://www.facebook.com/sharer.php?u= the_permalink();?>&t=" target="blank">Share on Facebook`

Now the users will be able to share your posts!

9. INSERTING ADVERTISEMENTS AFTER EVERY FIRST POST

Open up your index.php file and find the loop. Replace your loop with the following :-

`1`	`if (have_posts()) : ?>`

`2`	`$count = 0; ?>`

`3`	`while (have_posts()) : the_post(); ?>`

`4`	`$count++; ?>`

`5`	`if ($count == 2) : ?>`

`6`	`//Paste your ad code here`

7

"">

8

`9`	`else : ?>`

10

"">

11

`12`	`endif; ?>`

`13`	`endwhile; ?>`

`14`	`endif; ?>`

You can paste your ad code where it says “//Paste your ad code here”. Your loop might not be exactly replaceable so you can take hints from the above code and modify your loop accordingly.

10. AUTOMATIC CONTENT AFTER EACH POST

Many times, you want to add custom content/text after every post (e.g, subscribe to our blog link). Open up your functions.php file and add the following code to it :-

`1`	`function` `insertFootNote($content) {`

`2`	`if(!is_feed() && !is_home()) {`

`3`	`$content.=` `"` `";`

`4`	`$content.=` `"Enjoyed this article? ";`

`5`	`$content.=` `"Subscribe to our RSS feed and never miss a recipe! ";`

`6`	`$content.=` `"";`

7 }

`8`	`return` `$content;`

9 }

`10`	`add_filter ('the_content',` `'insertFootNote');`

I hope you enjoyed the above hacks and will make use of them. Please comment and let me know.

विन्डोज सेभेन नेपालीमा

nirajlimbu — Sun, 03 Jan 2010 04:52:00 +0000

नेपाली भाषामा कम्प्युटर चलाउन चाहनेका लागि आगामी वैशाख महिना विशेष रहनेछ। माइक्रोसफ्टले वैशाख महिनालाई विशेष बनाउन लागेको हो। वैशाखबाट कम्प्युटर सञ्चालन प्रणाली (ओएस) विन्डोज सेभेन अब प्रयोगकर्ताले नेपाली भाषामा चलाउन पाउनेछन्, त्यो पनि निशुल्क। विन्डोज सेभेनको अंग्रेजी संस्करणसम्म पहुँच नभएका एक्सपी र भिस्टाका उपभोक्तालाई समेत यसबाट थप राहत मिल्नेछ।

नेपाली विन्डोज सेभेनको विकास कार्य अन्तिम चरणमा पुगेको छ। ‘वैशाख महिनामा प्रयोगकर्तामाझ ल्याउनेगरी हामी तयारी गर्दैछौं,’ माइक्रोसफ्ट नेपालका प्रमुख एलन वैलोचन तुलाधर भन्छन्। माइक्रोसफ्टले यसअघि बजारमा ल्याएको ओएस भिस्टाको पनि नेपाली संस्करण बनाएको थियो।

विन्डोज सेभेन केही महिनाअगाडि मात्र बजारमा आएको हो। ओएस भिस्टाबाट ठक्कर खाएको माइक्रोसफ्टको विन्डोज सेभेन (अंग्रेजी संस्करण) सोचेभन्दा बढी विश्वबजारमा बिक्री भैरहेको छ। माइक्रोसफ्ट नेपालमार्फत विन्डोज सेभेन १० हजारभन्दा बढी नेपाली कलेज विद्यार्थीले निशुल्क आफ्ना पर्सनल कम्प्युटरमा राखिसकेका छन्। अब यो संख्या २० हजार पुर्‍याउन माइक्रोसफ्ट नेपाल लागेको छ। यसैबाट हौसिएको माइक्रोसफ्टले यसको नेपाली संस्करण नयाँ वर्ष २०६७ को उपहारस्वरुप निशुल्क नेपालीमाझ उपलब्ध गराउने तयारी गरेको छ।

// //

विन्डोज सेभेन (नेपाली संस्करण)

विन्डोज सेभेनको नेपाली र अंग्रेजी संस्करणमा खासै फरक छैन। मात्र भाषा फरक हुनेछ। ओएसमा प्रयोग गरिएका सम्पूर्ण फिचर्स हुबहु छन्। भाषासम्बन्धी फिचर्समा भने केही भिन्नता भेटिन्छ। माइक्रोसफट्को प्रावधान नै यस्तै छ – स्थानीयकरण गर्दा भाषाबाहेक अन्य फिचर्समा फेरबदल गर्न पाइने छैन। अर्थात, अंग्रजी संस्करणमा भन्दा नेपाली संस्करणका उपभोक्ताले बढी सुविधा पाउनेछन्।

अधिकांश प्रयोगकर्ताले विन्डोज एक्सपी ओस प्रयोग गरेका छन्। ज्यादै थोरैकोमा विन्डोज भिस्टा छ। भिस्टाभन्दा एक्सपी पुरानो ओएस भएपनि प्रयोगकर्ता भिस्टामा रहेका प्राविधिक कठिनाइका कारण एक्सपीमा अडिग रहे। यसैकारण माइक्रोसफ्टले भिस्टा ल्याएको तीन वर्ष बित्न नपाउँदै विन्डोज सेभेन ल्याउन बाध्य भयो।

नेपाली विन्डोज सेभेनमा अक्षरको आकार (फन्ट साइज) केही सानो पारिएको छ। साना ल्यापटप, नोट बुक र मोबाइलमा समेत स्क्रिन पूरा अटोस् भनेर अक्षरको आकार घटाइएको हो।

एक्सपी र भिस्टामा समावेश गरिएका सेवालगायत विन्डोज सेभेनमा थुप्रै नयाँ फिचर्स समावेश गरिएको छ। विन्डोज सेभेन बढी सुरक्षा केन्द्रित बनाइएको छ। र, यसको अर्को विशेषता भनेको अघिल्ला ओएसभन्दा यो बढी छिटोछरितो छ। धेरै नयाँ फिचर्स समेटिए पनि यसमा खास ७ वटा फिचर्स छन्, जसले प्रयोगकर्ताको ध्यान बढी खिच्नेछ। माइक्रोसफ्टले यसलाई ‘सेभेन वन्डर्स अफ विन्डोज सेभेन’ नाम दिएको छ।

१) बिट लकर

कम्प्युटर वा ल्यापटपको हार्डडिस्क चोरी भए अब डराउनु पर्दैन। हार्डडिस्कमा भएका डाटा कसैले पढ्न सक्ने छैनन्। हार्डडिस्कमा रहेका डाटाको सुरक्षा गर्नेछ ‘बिट लकर’ ले।

एक दसकयता बोकेर हिँड्ने प्रविधिको प्रयोग ह्वात्तै बढेको छ। मोबाइल, ल्यापटप, नोटबुक आदि हराउने वा चोरी हुने सम्भावन पनि उत्तिकै। पहिला हार्डडिस्क हराए वा चोरी भए अन्य कम्पयुटरमा राखेर पढ्न सकिन्थ्यो। डाटाको मिसयुज हुने सम्भावन उत्तिकै थियो। तर, विन्डोज सेभेनमा रहेको बिट लकरले कम्प्युटरको हार्डडिस्क लक गर्न सकिनेछ। लक गर्दा राखिएको पासवर्ड नमिलेसम्म हार्डडिस्कमा रहेका डाटा हेर्न सकिने छैन।

बिट लकर सेवा सजह रूपमा प्रयोग गर्न सकिन्छ। विन्डोज सेभेन इन्स्टल गरिसकेपछि ‘नियन्त्रण कक्ष’ (कन्ट्रोल प्यानल) मा गएर ‘सुरक्षा’ (सेक्युरिटी) आइकन क्लिक गर्नुपर्छ। त्यसपछि ‘बिट लकर’ मा डबल क्लिक गरी कुन ड्राइभलाई विट लक गर्ने छनौटगरी ‘ओके’ गरेपछि त्यहाँ रहेका डाटा सुरक्षित हुनेछन्। पाँच सय जिबी डाटालाई विट लक गर्न झन्डै सात घन्टा लाग्छ। तर एकपटक विट लक गरेपछि त्यो सदाका लागि हुनेछ।

बिट लकरले हराएको हार्डडिस्कबाट डाटा पुनः उपलब्ध भने गराउँदैन। यसले मात्र अरूले प्रयोग गर्न नसक्ने बनाउँछ। हार्डडिस्क चोरी गर्नेले तीन वर्षसम्म निरन्तर पासवर्ड परीक्षण गर्‍यो भनेचाहिँ हार्डडिस्क खुल्न सक्छ। तर तीन वर्ष निरन्तर पासवर्ड परीक्षण गरेर बस्ने फुर्सद नै कसलाई?

विन्डोज सेभेन सपोर्ट गर्ने मोबाइल प्रयोगकर्ताले समेत यो सुविधा पाउनेछन्। मोबाइल हराएमा एक एसएमएस पठाएको भरमा मोबाइलमा रहेका सम्पूर्ण डाटा मेटाउन सक्नेछन्।

बिट लकर सेवा उपभोग गर्दा अलि बढी नै होसियार रहनुपर्छ। यदि लगातार तीन पटकसम्म पासवर्ड गलत हानिएमा त्यसपछि कम्प्युटर नखुल्ने मात्र होइन हार्डडिस्कमा रहेका सम्पूर्ण डाटा मेटिनेछन्। जसलाई पुनः पाउन असम्भव छ।

२) युजर इन्टरफेस

विन्डोज सेभेनले प्रयोगकर्तालाई कम्प्युटर चलाउन निकै सहज बनाउने देखिन्छ। धेरैजसो कमान्ड एक क्लिकका भरमा उपलब्ध हुने बनाइएको छ। बढी प्रयोग गरिएका कमान्ड टुलबारमै रहनेछन्। टुलबारमा रहेका कमान्डमा माउस राइट क्लिक गरे सम्बन्धित कमान्डमा पछिल्लो समय काम गरिएका फाइल पनि उपलब्ध गराउनेछ।

जस्तो एक्सपी र भिस्टामा माइक्रोसफ्ट वर्ड खोल्न परे माउस तीन-चार पटक क्लिक गरेपछि मात्र सम्भव हुन्थ्यो। विन्डोज सेभेनले यस्ता सुविधा एक क्लिकमा उपलब्ध गराउँछ। कमान्ड खोजेर बस्नुपर्ने झन्झटबाट विन्डोज सेभेनले उपभोक्तालाई मुक्ति दिनेछ।

३) डेस्कटप सर्च

डेस्कटप सर्चलाई पहिलेका ओएसमा भन्दा निकै सशक्त पारिएको छ। सर्चमा गएर कुनै पनि शब्द टाइप गर्न थालेपछि पहिला त टाइप गरिएका अक्षरसँग मिल्नसक्ने शब्द सुझावका रूपमा प्रस्तुत गर्नेछ। शब्द पूरा टाइप गरिसकेपछि इन्टर नहान्दै सम्बन्धित शब्दसँग मेल खाने सम्पूर्ण फाइल देखाउनेछ। यसअघिका ओएसले यति छिटो र सुक्ष्म तरिकाले फाइल खोज्न सक्दैनथे।

४) इन्टरनेट एक्सप्लोरर एट

माइक्रोसफ्टले नयाँ ओएसमा इन्टरनेट एक्सप्लोररलाई उच्च प्राथमिकतासाथ डिजाइन गरेको छ। ‘इन्टरनेट एक्सप्लोरर एट’ विन्डोज सेभेनमा समावेश गरिएको नयाँ सुविधा हो। यसमा नयाँ फिचर्स ‘ट्याब’ राखिएको छ। सधैं खोलिरहनुपर्ने वेबसाइट ट्याबमा भेटिनेछन्।

इन्टरनेट एक्सप्लोरर एटको विशेषता भनेको यसले सपोर्ट नगर्ने वेबसाइट पनि पुरानै एक्सप्लोररमा गएर खोलिदिन्छ। जसका कारण वेबसाइटको स्वरुप बिग्रन पाउँदैन र आफूलाई चाहिने सूचना पढ्न तथा डाउनलोड गर्न सघाउनेछ। यदि कुनै वेबसाइटलाई इन्टरनेट एक्सप्लोरर एटले सपोर्ट गरेन भने ‘एड बार’ को दायाँपट्टी रहेको ‘मिल्दोजुल्दो दृश्य’ आइकनमा क्लिक गरेपछि पुरानो शैलीको एक्सप्लोररमा वेबसाइट खुल्नेछ।

यसमा सुरक्षा अनुप्रयोग (सेफ्टी फिचर्स) मजबुत छ। सुरक्षा टुलबारमा रहेको ‘इनप्राइभेट ब्राउजिङ’ क्लिक गरी इन्टरनेट चलाए हेरिएका कुराहरू लोकल हार्डडिस्कमा गएर बस्दैन। यो सुविधा पुराना ओएसमा थिएन। ‘फ्यामेली सेफ्टी’ (पारिवारिक सुरक्षा) यसमा पाइने अर्को राम्रो फिचर्स हो। यो फिचर्स अन गरिदिए बच्चाले नचाहिने कुरा इन्टरनेटमा हेर्न सक्ने छैनन्। यसका लागि बच्चाको छुट्टै लगइन चाहिन्छ।

इन्टरनेट एक्सप्लोरर एटको अर्को राम्रो पक्ष – यसले खोलिएका वेबसाइटका ठेगानालाई हाइलाइट गरेर देखाउँछ। हाइज्याक गरिएका वेबसाइट हेरिएको छ वा वास्तविक यही हाइलाइट हेर्नेबित्तिकै थाहा पाउन सकिन्छ। कहिलेकाहीँ एउटा वेबठेगाना हान्यो तर अर्कै साइट खुल्छ, जुन सामान्य प्रयोगकर्ताले थाहा पाउन गाह्रो थियो। तर अब यसको समाधान ल्याएको छ नयाँ एक्सप्लोररले।

५) क्यालकुलेटर

३० वर्षपछि माइक्रोसफ्टले क्यालकुलेटरमा फेरबदल गरेको छ। नेपाली विन्डोज सेभेनमा समावेश गरिएको क्यालकुलेटरबाट अब माना, पाथी, धार्नीमा समेत हिसाबकिताब गर्न सकिनेछ। कति मानाको पाथी, कति किलोको धार्नी सबै क्यालकुलेटरले सिकाउनेछ। केजीलाई धार्नी, माना, पाथीमा लैजानसमेत क्यालकुलेटर सक्षम छ। क्यालकुलेटरमा फिट, मिटर, रोपनी, बिगा, हात सबैमा हिसाब गर्न सकिनेछ। वैज्ञानिक र प्रोगामर दुईथरी क्यालकुलेटरलाई मर्ज गरी एउटा बनाइएको हो।

क्यालकुलेटरले पुराना क्यालेन्डर खोज्न नपर्ने पनि बनाएको छ। किनकी क्यालकुलेटरबाटै विक्रम सम्बतलाई इस्वी सम्बतमा लान सकिनेछ। अझ स्पष्ट भन्नुपर्दा एक्सएलका धेरै सुविधा क्यालकुलेटरमा समावेश गरिएको छ।

कति अंकको बीचमा कमा राख्ने हो त्यो क्यालकुलेटरमा आफै मिलाउन सकिनेछ। यसमा क्यालकुलेसन इतिहाससमेत हेर्न सकिन्छ। क्यालकुलेटरमा गरिएका हिसाब मेमोरीमा गएर बस्छ। त्यहीबाट पुराना जोडघटाउ हेर्न सकिनेछ।

६) वाचन पहिचान (स्पिच रिकग्नाइजेसन)

विन्डोज सेभेनको अर्को आकर्षक अनुप्रयोग ‘वाचन पहिचान’ हो। विन्डोज सेभेनमा मौखिक आदेशका भरमा कम्प्युटर सञ्चालन गर्न सकिन्छ। बिनाकिबोर्ड र माउस यसमा काम गर्न सकिन्छ। जे बोल्यो त्यो कम्प्युटरले आफै टाइप गर्छ। यति मात्र होइन, यसले ह्रस्वदिर्घसमेत मिलाउन सक्छ। आवाजबाट पाठ (स्पिच टु टेक्स्ट) र पाठबाट आवाज (टेक्स्ट टु स्पिच) दुवै सुविधा यसमा छन्। अर्थात यसले पाठलाई पढेर सुनाउन र आवाजलाई पाठमा लैजान सक्छ।

नेपाली विन्डोज सेभेनको शब्दावलीमा ५८ हजार नेपाली मूल शब्द समावेश गरिएको छ। जसबाट दुई करोड नेपाली शब्द बनेका छन्। जसमध्ये ५ हजारभन्दा बढी त प्राविधिक शब्द नै छन्। गालीगलौज, मानहानी, विभेद जनाउने तीनसय भन्दा बढी शब्द यसमा ब्लक गरिएको छ।

७) मल्टिटच फिचर्स

विन्डोज सेभेन माउस, किबोर्ड, मौखिक आदेशको भरमा मात्र होइन औंलाले छोएर पनि चलाउन सकिन्छ। टच स्क्रिन मोबाइल निर्मातालाई चुनौती दिने गरी वन्डोज सेभेन विकास गरिएको छ। आइफोनमा जस्तै यसमा पनि औंलाले छोएर सबै काम गर्न सकिन्छ। तर, यसका लागि टच स्क्रिन मनिटर हुन अनिवार्य छ।

भिस्टामा सिंगल टच मात्र सम्भव थियो। विन्डोज सेभेनमा मल्टिटच सम्भव छ। विन्डोज सेभेन राखिएको ल्यापटपको स्क्रिनमात्र होइन ‘टच प्याड’ बाट पनि मल्टिटच सुविधा प्रयोग गर्न सकिनेछ। स्क्रिनमा औंला चलाएको भरमा तस्बिर सानोठूलो, पाठ टाइप गर्न सकिनेछ।

अन्य महत्त्‍वपूर्ण सुविधा

विन्डोज सेभेनमा अन्य यस्ता सुविधा पनि छन् जुन पहिलाका ओएसमा समावेश गरिएको थिएन। यी सुविधा प्रयोग गर्न पाउँदा साँच्चै नै प्रयोगकर्ता एकछिन चकित पर्नेछन्। ‘पावर सेल’ यिनैमध्ये एउटा सुविधा हो। यसमा डस, लिनक्स र म्याकका कमान्ड चलाउन सकिन्छ। माउस र किबोर्डले गर्न नसक्ने कम्प्युटर नियन्त्रण पावर सेलबाट गर्न सकिन्छ। खासगरी यो प्राविधिक प्रयोगकर्ताको लागि बनाइएको हो।

विन्डेज सेभेनभित्र रहेर पुरानो ओएस एक्सपी पनि चलाउन सकिन्छ। यो यसको अर्को विशेषता हो। एक्सपीका प्रयोगकर्ता बढी भएका कारण माइक्रोसफ्टले यसलाई चलाउन मिल्ने गराएको हो। अर्थात नयाँ र पुरानो प्रविधि एकसाथ चलाउन सकिनेछ। ‘विन्डोज एक्सपी मोड’ डाउनलोड गरेपछि मात्र विन्डोज सेभेनभित्र रहेर एक्सपी चलाउन सकिनेछ। विन्डोज एक्सपी मोड इन्टरनेटबाट निशुल्क डाउनलोड गर्न पाइन्छ।

‘एरो सेक’ अर्को महत्त्‍वपूर्ण सेवा यसमा समावेश गरिएको छ। खोलिएकोमध्ये अगाडिको विन्डोमा गएर माउसको एरो हल्लाउने हो भने पछाडिका सबै विन्डो मिनिमाइज हुन्छन्। माउसको एरो पुनः हल्लाए मिनिमाइज भएका सबै विन्डो खुल्छ।

अर्को महत्त्‍वपूर्ण सुविधा भनेको नेपाली विन्डोज सेभेन राखिएको कम्प्युटरमा यसको अंग्रेजी संस्करण पनि एकसाथ चलाउन सकिनेछ। यो सुविधा पहिलेको ओएसमा थिएन। पहिला नेपालीबाट अंग्रेजी संस्करणमा जानुपरे कम्प्युटर ‘रिबुट’ गर्नुपर्थ्यो। विन्डोज सेभेनमा बहुबुट गर्ने सुविधा राखिएको छ। एकसाथ नेपाली र अंग्रेजी संस्करण इन्स्टल गर्न सकिनेछ।

इन्स्टल कसरी गर्ने

विन्डोज सेभेनको नेपाली र अंग्रेजी संस्करण इन्स्टल गर्ने प्रक्रिया, यसको लागि चाहिने आवश्यक न्यूनतम हार्डवेयर सबै एउटै हो। अंग्रेजीजस्तै नेपाली संस्करण पनि ३२ बिट र ६४ बिट कम्प्युटरमा चल्नेछ। यी दुवै कम्प्युटरका लागि भिन्दाभिन्दै ओएस तयार पारिएको छ। तर, सुविधामा भने खासै भिन्नता छैन।

विन्डोज सेभेनको लागि सिपियु एक गिगा हर्ज वा योभन्दा द्रुत गतिको चाहिन्छ। र्‍याम भने ३२ बिट कम्प्युटरमा एक गिगा बाइट्स (जिबी) र ६४ बिट कम्प्युटरमा दुई जिबी हुन जरुरी छ। ग्राफिक्स प्रोसेसिङ युनिट ‘एरो क्यापेबल’ छ। भिडियो र्‍याम १२८ मेगाबाइट्स (सेयर्ड) आवश्यक पर्छ। हार्डडिस्क ३२ बिट कम्प्युटरको लागि १६ जिबी र ६४ बिट कम्प्युटरको लागि २० जिबी अनिवार्य छ। अप्टिकल ड्राइभमा डिभिडी वा युएसबीमध्ये एक भए हुन्छ।

विन्डोज सेभेन इन्स्टल गर्ने सोच छ भने पहिला आफ्नो कम्प्युटर तथा ल्यापटपमा माथि उल्लेख गरिएका न्यूनतम हार्डवेयर आवश्यकता मेल खान्छ कि खाँदैन चेक गर्नुपर्छ। यो थाहा पाउन गाह्रो छैन।
१) पहिला कम्प्युटरको ‘स्टार्ट’ बटन क्लिक गर्नोस्
२) त्यसपछि ‘माई कम्प्युटर’ मा राइट क्लिक गर्नोस्, अनि ‘प्रोपर्टिज’ मा
यति गरेपछि ‘सिस्टम प्रोपर्टिज’ स्क्रिनमा खुल्छ। त्यहीँ सबै जानकारी राखिएको हन्छ – कम्प्युटरमा कुन ओएस छ, कति जिबी हार्डडिस्क, र्‍याम कति छ, कति बिटको कम्प्युटर आदि। सिस्टम प्रोपर्टिजमा यदि ‘एक्स ६४ एडिसन’ देखिएन भने बुझ्नुपर्नेछ कम्प्युटर ३२ बिटमा चलिरहेको छ।

यदि तपार्इंको कम्प्युटरमा एक्सपी र भिस्टामध्ये एक ओएस छ भने बुझ्नुपर्नेछ त्यसमा विन्डोज सेभेन चल्नेछ। सम्भवतः विन्डोज सेभेन ३२ बिट कम्प्युटरमा चल्ने माइक्रोसफ्टको अन्तिम ओएस हुनेछ। धेरै प्रयोगकर्ता एक्सपीमै अडिग रहेका कारण विन्डोज सेभेनलाई ३२ बिट कम्प्युटरमा समेत चल्नेगरी विकास गरिएको हो।

एक्सपी ओएस रहेको कम्प्युटरमा केवल ‘सी’ ड्राइभ मात्र फरम्याट गरे हुन्छ। पहिला सी ड्राइभमा रहेका आवश्यक फाइललाई सुरक्षित राख्नुपर्छ। यसको लागि माइक्रोसफ्टको आधिकारिक साइटमा गएर ‘विन्डोज इजी ट्रान्फर’ (बेट) टुल डाउनलोड गर्नुपर्छ। यो डाउनलोड गर्नेबित्तिकै सी ड्राइभमा रहेका फाइल ब्याकअप गर्नेछ। अनि सुरु गर्नुपर्छ विन्डोज सेभेन इन्स्टल गर्न। इन्स्टल भैसकेपछि कम्प्युटरमा रहेको बेट टुलमा गएर क्लिक गरेपछि सी ड्राइभका फाइल पुनः प्राप्त गर्न सकिन्छ।

Top Search Engine Optimization Tips

nirajlimbu — Wed, 30 Dec 2009 15:21:51 +0000

Getting a high rank on search engines through user keyword searches can be difficult, but with proper focus on writing your blog posts for search engine optimization (SEO), you can boost your rank for specific keyword searches and your blog’s traffic. Follow these tips to get the biggest results.

1. Check the Popularity of Keywords

In order to obtain traffic from keyword searches on the major search engines like Google and Yahoo!, you need to be writing about a topic that people want to read about and are actively looking for information about. One of the easiest ways to get a basic idea of what people are looking for online is to check the popularity of keyword searches on websites like Wordtracker, Google AdWords, Google Trends or the Yahoo! Buzz Index. Each of these sites provides a snapshot of keyword popularity at any given time.

2. Select Specific and Relevant Keywords

A good rule to go by is to select one keyword phrase per page then optimize that page to that keyword phrase. Keywords should be relevant to the overall content of your page. Furthermore, choose specific keywords that are more likely to give you a better search results ranking than a broad term would. For example, consider how many sites use the keyword phrase of “punk music.” The competition for ranking using that keyword is likely to be tough. If you choose a more specific keyword like “Green Day concert,” the competition is a lot easier.

3. Select a Keyword Phrase of 2 or 3 Words

Statistics show that nearly 60% of keyword searches include 2 or 3 keywords. With that in mind, try to optimize your pages for searches on keyword phrases of 2 or 3 words to drive the biggest results.

4. Use Your Keyword Phrase in Your Title

Once you select the keyword phrase you plan to optimize your page for, make sure you use that phrase in the title of your blog post (or page).

5. Use Your Keyword Phrase in Your Subtitle and Headlines

Breaking blog posts up using subtitles and section headlines not only makes them more visually appealing on a text heavy computer screen, but it also gives you additional opportunities to use your keyword phrase.

6. Use Your Keyword Phrase in the Body of Your Content

It’s important that you use your keyword phrase in the body of your blog post. A good goal to try to achieve is to use your keyword phrase at least twice in the first paragraph of your post and as many times as you can (without keyword stuffing – see #10 below) within the first 200 (alternatively, the first 1,000) words of your post.

7. Use Your Keyword Phrase in and Around Your Links

Search engines count links higher than plain text in their search algorithms, so try to create links that use your keyword phrase. Avoid using links that simply say, “click here” or “more information” as these links will do nothing to help you with your search engine optimization. Leverage the power of links in SEO by including your keyword phrase in them whenever possible. The text surrounding links is typically weighted more heavily by search engines than other text on your page as well. If you can’t include your keyword phrase in your link text, try to include it around your link text.

8. Use Your Keyword Phrase in Images

Many bloggers see a large amount of traffic sent to their blogs from image searches on search engines. Make the images you use in your blog work for you in terms of SEO. Make sure your image filenames and captions include your keyword phrase.

9. Avoid Block Quotes

There are differing opinions on this issue with one group of people saying that Google and other search engines ignore the text included in the HTML block quote tag when crawling a web page. Therefore, the text within the block quote tag won’t be included in terms of SEO. Until a more definitive answer can be determined to this issue, it’s a good idea to keep it in mind and use the block quote tag cautiously.

10. Don’t Keyword Stuff

Search engines penalize sites that stuff pages full of keywords simply to increase their rankings through keyword searches. Some sites are even banned from inclusion in search engine results because of keyword stuffing. Keyword stuffing is considered a form of spamming, and search engines have zero tolerance for it. Keep this in mind as you optimize your blog posts for search engines using your specific keyword phrase.

The blogosphere is a big and busy world with over 100 million blogs and growing. How do you attract visitors to your blog? Follow these simple tips to drive traffic to your blog.

1. Write Well and Write Often

Frequently updating your blog with useful content is the first step to building your blog’s audience. The content you write is what will keep readers coming back for more. Make sure you have something meaningful to say to them and say it often to maintain their interest and keep them loyal.

Furthermore, post frequently to increase the number of chances you have for your blog’s content to be noticed by search engines such as Google or Technorati.

2. Submit Your Blog to Search Engines

Get on the radar screen for the popular search engines such as Google and Yahoo! by submitting your blog’s URL to them. Most search engines provide a ‘Submit’ link (or something similar) to notify the search engine of your new blog, so those search engines will crawl it and include your pages in their results.

It’s important to understand that simply submitting your blog to search engines doesn’t mean your pages will appear at the top of a Google search results screen, but at least your blog will be included and will have the chance of being picked up by a search engine.

3. Use and Update Your Blogroll

By adding links to sites you like in your blogroll, the owners of those blogs will find your blog and will be likely to add a reciprocal link in their blogrolls. It’s an easy way to get the link to your blog in front of many readers on other blogs. The hope is that some of those readers will click on the link to your blog on the other blogs’ blogrolls and find your content interesting and enjoyable turning them into loyal readers.

4. Harness the Power of Comments

Commenting is a simple and essential tool to increase your blog’s traffic. First, respond to comments left on your blog to show your readers that you value their opinions and draw them into a two-way conversation. This will increase reader loyalty.

Second, leave comments on other blogs to drive new traffic. Make sure you leave your blog’s URL in your comment, so you create a link back to your own blog. Many people will read the comments left on a blog post. If they read a particularly interesting comment, they are highly likely to click on the link to visit the commentor’s website. It’s important to make sure you leave meaningful comments that are likely to invite people to click on your link to read more.

5. Syndicate Your Blog’s Content with an RSS Feed

Setting up an RSS feed button on your blog makes it easy for your loyal readers to not just read your blog but also know when you publish new content.

6. Use Links and Trackbacks

Links are one of the most powerful parts of your blog. Not only are links noticed by search engines, but they also act as a tap on the shoulder to other bloggers who can easily identify who is linking to their sites. Linking helps to get you noticed by other bloggers who are likely to investigate the sites that are linking to them. This may lead them to become new readers of your blog or to add links to your blog from theirs.

You can take links to other blogs a step further by leaving a trackback on the other blog to let them know you’ve linked to them. Blogs that allow trackbacks will include a link back to your blog in the comments section of the post that you originally linked to. People do click on trackback links!

7. Tag Your Posts

It takes a few extra seconds to add tags to each of your blog posts, but it’s worth the time in terms of the additional traffic tags can drive to your blog. Tags (like links) are easily noticed by search engines. They’re also key to helping readers find your blog when they perform searches on popular blog search engines such as Technorati.

8. Submit Your Posts to Social Bookmarking Sites

Taking the time to submit your best posts to social bookmarking sites such as Digg, StumbleUpon, Reddit and more can be a simple way to quickly boost traffic to your blog.

9. Remember Search Engine Optimization

When you write your blog posts and pages, remember to optimize your pages for search engines to find them. Include relevant keywords and links but don’t overload your posts with too many relevant keywords or completely irrelevant keywords. Doing so can be considered spamming and could have negative results such as your blog being removed from Google’s search entirely.

10. Don’t Forget Images

Images don’t just make your blog look pretty, they also help people find you in search engine listings. People often use the image search options offered by Google, Yahoo! and other search engines, and naming your images with search engine optimization in mind can easily boost your traffic.

ईन्टरनेटको ४० औ जन्म दिन

nirajlimbu — Mon, 02 Nov 2009 09:59:29 +0000

इन्टरनेटविनाको कम्प्युटरको सास विनाको शरिर समान बनिसकेको छ । अहिलेको समयमा इन्टरनेट हरेकको अत्यावश्यक बनिसकेको छ चाहे ति गृहणी हुन या विद्यार्थी, प्राध्यापक हुन या अन्य केही पेशाकर्मी । सबैको दैनिकीमा अनिवार्य बनिसकेको छ । यो जादुमय प्रविधिले एक क्लीकमा विश्वलाई कैद गरिसकेको छ । यही जादुमयी प्रविधि विहिवारवाट ४० वर्ष टेकेको छ ।

इन्टरनेटवाट फैलिएको बौद्धिक जाल र यसको बढ्दो महत्व हेर्ने हो भने यसका प्रणेता लेन क्लिनरांकले फेसबुक, ट्विटर या आरकुट जस्ता सोसियल नेटवर्किगं साइटको सायदै कल्पना गरेका थिए होला , जो अहिलेका इन्टरनेट प्रयोगकर्ताहरुका लागि यसको प्रयोग अनिवार्य दिनचर्या बनिसकेको छ ।

अमेरिकाको लसएन्जलसमा रहेको क्यालीफोर्निया विश्वविद्यालयका प्रोफेसरहरुले २ सेप्टेम्बर १९६९ मा पहिलोपटक दुई कम्प्युटरलाई १५ मिटर तारले जोडेर एक आपसको डाटाहरु साटफेर गर्न सफल भएका थिए । इन्टरनेटको पहिलो डमी यसैलाई मानिन्छ । २९ अक्टोवर १९६९ मा लेन क्लिनरांकले परिक्षण मार्फत यसलाई इन्टरनेट प्रविधिको रुपमा विकास गर्न सफल भएका थिए ।

सन १९७१ म पहिलो पटक इमेलको सुत्रपात भएको रहेछ । रेय टेम्लीसनले पहिलोपटक पहिलो पटक ईमेल पठाएका थिए । इमेलमा प्रयोग गरिने २ को प्रारम्भ उनैले गरेका हुन । अहिले प्रयोगमा आएको डट कम, डट नेट जस्ता डोमेनको स्वरुप १९८५ मा सुत्रपात्र भएको थियो ।

नोभेम्बर २ १९८८ मा इन्टरनेटको व्यापक रुपमा पहिलो पटक प्रयोग भएको थियो । १९९० मा आएर टिन वनर्सले इन्टरनेट मार्फत सुचना आदान प्रदान गर्ने प्रविधि बल्डवाइड वेभ अर्थात डब्लुडब्लुडब्लुको प्रारम्भ गरेका थिए ।

इन्टरनेट प्रविधिको आकार प्रकार आइसकेपनि अमेरिकी सरकारले सर्वसाधारणको प्रयोगका लागि भने प्रतिबन्ध लगाएको थियो । सन १९९५ मा आएर जव अमेरिकी सरकारले सर्वसाधारणले इन्टरनेटको प्रयोग गर्न नपाउने कानुन खारेज ग¥यो तव यो सबैको भयो । आईसिएएनएनका अनुसार अहिले विश्वभर करिव एक अर्ब ५० करोड ब्यक्ति इन्टरनेट चलाउछन । इन्टरनेट प्रयोगकर्ताको हिसावमा चीन सबैभन्दा अगाडि रहेको छ भने भारत चौथो नम्बरमा रहेको छ ।

Blank page while working in Drupal

nirajlimbu — Mon, 02 Nov 2009 07:49:14 +0000

If you are using Drupal Theme for your blog or website then one of the most to be careful thing is blank page while updating some new blocks or modules from Admin menu.

if really irritates while getting such blank page and while not seeing any reverse options to get back in previous stage.

but no panic.

if you are using Wamp sever then you need to increase memory size of PHP.

how to to it?

go to your installed PHP directory or go through Icon which you see in system try bar.

if you are going through Icon then click on it >Configure Files>PHP.ini

once it’s opened then fine following things:

o post_max_size=8M o upload_max_filesize=2M o max_execution_time=60 o max_input_time=30

then you just need to change those as you like and restart all services.

that's it.

XP,Vista Vs Windows 7

nirajlimbu — Sun, 25 Oct 2009 12:27:46 +0000

Microsoft, the undisputed leader in business productivity software, has almost enjoyed a monopoly in the market of operating systems for personal computers. This week, on October 22nd, Microsoft launched its latest version of operating system called Windows 7. According to many, Microsoft’s last venture, Windows Vista, was a failure thanks to the reasons like poor marketing, faster battery drain in the laptops, higher system requirements, missing drivers, poor overall performance, missing file system like winFS and so on. Windows Vista could get a share of less than 10% installation on the corporate computers. Microsoft itself did admit that Vista was not a success after all. Now we are entering into the age of Windows 7 but the question is “Will Windows 7 Replace XP and Vista?” I am going to share my opinions with you all with the help of this post.

After a great success of Windows XP, Vista came up. Unfortunately Vista was unable to replace XP and couldn’t come even close to XP if we talk about its share in terms of use. Still 60% of the businesses are using XP environment because they believe that it works best for their working needs. There are quite a few companies still using Windows 2000 that’s because there are some particular applications which may not be compatible with XP but other than that most companies use Windows XP. Besides this, the world seems to be in love with Windows XP. People want to keep it in market especially after their experience with Windows Vista, and this makes Vista look even worse. There are some reports about people reverting back to XP after finding the drawbacks of Vista.

Windows Vista is out for quite some time now. Vista originally came carrying a goal to replace XP but failed to leave even its own footprint. I have encountered very few instances of a company using it in their work environment. To many, Vista is nothing better than a piece of junk. Vista is being used mainly by either home users or those who use the computer for their home/ personal use because they do not have a choice other than using it. Here in the United States, most of the outlets like Best Buy, CompUSA, Circuit City, Wal-Mart, Sams Club, Costco etc. were selling computers with only Vista preloaded (before Windows 7 was launched). When People ask to uninstall Vista, they charge some additional money ($99.00) to remove Vista and put XP back on (except for some Vista ultimate users who had an option to get their operating system down- graded for free). The percentage of people who don’t know anything about an operating system despite of using computer for a long time is fairly high even now. For people who fall under this category may not have any issues either by with XP or with Vista. So basically Microsoft is forcing people to buy the computers with Vista pre-loaded. This way, Microsoft still making profit whether you take the computer as it is or even if you ask them replaces Vista with XP at additional $99.00. Let’s forget the Vista here but do keep the XP in mind and let’s move towards the new innovation, Windows 7.

Windows XP has been the best operating system for almost a decade now but is it the turn for Windows 7? Many People say that Windows 7 seems to be nothing more than some polish applied liberally to the Vista Aero theme. I would say, please do not jump into this conclusion so early, because windows 7 seems to be a complete replacement of Vista and much better than Vista in terms of performance. Windows 7 is more than just spin. It’s stable, smooth, and highly polished operating system introducing new graphical features, a new taskbar that can compete handily with the Mac OS X dock, and device management and security enhancements that make it both easier to use and safer. Importantly, it won’t require the hardware upgrades that Vista demanded (at least Microsoft claims it). The reason behind this is partially because the hardware has caught up, and partially because Microsoft is eager to make Windows 7 accessible to as many people as possible.

Microsoft is offering six versions of Windows 7: Starter, Home Premium, Professional, Ultimate, OEM, and Enterprise. The three versions that Redmond will be promoting most heavily are Home Premium, Professional, and Ultimate, although Starter will also be available to consumers. Windows 7 will support both 32-bit and 64-bit systems. The bare minimum requirements for the 32-bit include a 1GHz processor, 1GB RAM, 16GB available hard-disk space, and a DirectX 9 graphics device with WDDM 1.0 or higher driver. 64-bit systems will require at least a 1 GHz processor, 2GB RAM, 20GB of free space on your hard drive, and a DirectX 9 graphics device with WDDM 1.0 or higher driver. A touch-screen monitor is required to take advantage of the native touch features. Do note that some users have claimed to have limited success running the Windows 7 beta with less than 1GB of RAM, but that’s not recommended.

The good: Strong design and Microsoft don’t always go together, but they do in Windows 7. Users might take a while to get used to the new taskbar and Aero Peek, but they’re a pleasure to use.

The bad: Performance is still hit-or-miss in Windows 7. At the ripe age of seven, Windows XP still performs better in some categories.

The bottom line: Windows 7 is more than what Vista should have been, it’s where Microsoft needed to go. How much damage Vista did and whether Windows 7 is enough for people to finally abandon Windows XP are questions that nobody has the answers to right now. (source: CNET)

I have recently installed the Windows 7 on my computer. The first impression of this looks okay to me and I would encourage users to install it. It looks like the operating system consumers have been waiting for. Microsoft claims to have fixed most of the problems that were in Vista and believes that Windows 7 is the future of Windows brand of operating systems
