  • category title and affect on SEO and ranking [closed]

    - by Mark
    We are working on a jobs and skills website (similiar to Skill Pages) and are deciding on the names of categories. Rather than having loads of categories and sub-categories like, for example, Builder, Electrician, Carpenter etc, we would like to have more general and easier on the eye category names. So for example we have House, Computer, Education, Art etc. So a builder would be in category House and a few others. Will this style negatively effect our SEO and ranking? And if so, should we abandon and go back to traditional categories and sub-categories?

  • Book Review (Book 10) - The Information: A History, a Theory, a Flood

    - by BuckWoody
    This is a continuation of the books I challenged myself to read to help my career - one a month, for year. You can read my first book review here, and the entire list is here. The book I chose for March 2012 was: The Information: A History, a Theory, a Flood by James Gleick. I was traveling at the end of last month so I’m a bit late posting this review here. Why I chose this book: My personal belief about computing is this: All computing technology is simply re-arranging data. We take data in, we manipulate it, and we send it back out. That’s computing. I had heard from some folks about this book and it’s treatment of data. I heard that it dealt with the basics of data - and the semantics of data, information and so on. It also deals with the earliest forms of history of information, which fascinates me. It’s similar I was told, to GEB which a favorite book of mine as well, so that was a bonus. Some folks I talked to liked it, some didn’t - so I thought I would check it out. What I learned: I liked the book. It was longer than I thought - took quite a while to read, even though I tend to read quickly. This is the kind of book you take your time with. It does in fact deal with the earliest forms of human interaction and the basics of data. I learned, for instance, that the genesis of the binary communication system is based in the invention of telegraph (far-writing) codes, and that the earliest forms of communication were expensive. In fact, many ciphers were invented not to hide military secrets, but to compress information. A sort of early “lol-speak” to keep the cost of transmitting data low! I think the comparison with GEB is a bit over-reaching. GEB is far more specific, fanciful and so on. In fact, this book felt more like something fro Richard Dawkins, and tended to wander around the subject quite a bit. I imagine the author doing his research and writing each chapter as a book that followed on from the last one. This is what possibly bothered those who tended not to like it, I think. Towards the middle of the book, I think the author tended to be a bit too fragmented even for me. He began to delve into memes, biology and more - I think he might have been better off breaking that off into another work. The existentialism just seemed jarring. All in all, I liked the book. I recommend it to any technical professional, specifically ones involved with data technology in specific. And isn’t that all of us? :)

  • Prove that the set of regular languages is a proper subset of the set of the context-free languages

    - by David Relihan
    I was brushing up (not homework)on some computation-theory and came accross this problem: How can you prove that the set of regular languages is a proper subset of the set of the context-free languages. Now I know a language is regular iff it is accepted by a finite automaton. And I know a language is context-free iff it is accepted by a pushdown automaton. But I'm not sure of what solution is.

  • Can a website become popular in a "category" (ie, not just a single page)

    - by Earlz
    I have a few keywords where my website is high ranking(2nd and 3rd result). For instance, I have 3 blog posts covering a certain kind of modem. Is it common for search engines to consider a website popular in a "category"? For instance, if I was the first result for "foobar" with one page, and then added another separate page which mentioned "foobar"(and maybe a link from the original page), would a search engine prioritize this separate page when compared to a completely separate website with a page with the same content?

  • problem in counting children category

    - by moustafa
    I have this table: fourn_category (id , sub) I am using this code to count: function CountSub($id){ $root = array($id); $query = mysql_query("SELECT id FROM fourn_category WHERE sub = '$id'"); while( $row = mysql_fetch_array( $query, MYSQL_ASSOC ) ){ array_push($root,$row['id']); CountSub($row['id']); } return implode(",",$root); } It returns the category id as 1,2,3,4,5 to using it to count the sub by IN() But the problem is that it counts this: category 1 category 2 category 3 category 4 category 5 Category 1 has 1 child not 4. Why? How can I get all children's trees?

  • The Grand Unified Framework Theory

    Tom Janssens left a comment: What still bugs me is that we do not have a unified pattern for all .net dev (using modelbinders and icommand for example...) But, Tom we are pretty close. At least as close as we should be, I think. With .NET there are plenty of low level patterns we can reuse regardless of the application platform or architecture. Stuff like: Asynchronous programming with events or the TPL. Object queries with LINQ. Resource management with IDispose. At a higher...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • PageRank is the Best Indicator of Competition Strength For a Keyword in SEO - New Verifiable Theory

    The major argument against PageRank in SEO is that pages with zero PageRank can be in the top positions even for highly competitive keywords. However, we are left with requiring an explanation as to why "PageRank is Google's view of the importance of this page." It becomes apparent that either Google is misleading us or we have all been misinterpreting Google's statement. From extensive evaluation of the top Google search engine results pages for hundreds of keywords, the author observed that those high positioned web pages with PageRanks of zero have a home page with higher PageRanks, usually three or more.

  • SEO: Joomla Category Page Optimization + Canonical Linking

    - by Huberis
    I'm wondering how best to optimize my Joomla site's SEO. I have pages with multiple articles on each page. Either via category-type pages, or via modules. In each case, I'm not wanting users to access the articles separately from the forward facing, menu-linked pages. I understand however that Joomla still generates a url for those articles, and Google can still crawl and display these articles separate from the pages. My question is what is the best way to control this so that my users get directed only to the front-facing pages? By using the canonical element for each article to point to the front-facing page it's on? Or is there a better method? Thanks for your help!

  • 2-D Lighting Theory

    - by Richard
    I am writing a rogue-like 'zombie' management game. The game map will be similar to Prison Architect. A top-down 50 X 50 grid. I want to implemented a day night cycle and during the night I would like the player to be able to position lights. I would like to be able to lighten and dark to whole map to display the day and night cycle. Then lights would be a circle of light blocked by game entities such as walls, players, trees etc. How would I achieve and what is the standard way of achieving this?

  • Rails 3 - Category Filter Using Select - Load Partial Via Ajax

    - by fourfour
    Hey. I am trying to filter Client Comments by using a select and rendering it in a partial. Right now the partial loads @client.comments. I have a Category model with a Categorizations join. This all works, just need to know how to get the select to call the filter action and load the partial with ajax. Thanks for you help. Categories controller: def filter_category @categories = Category.all respond_to do |format| format.js # filter.rjs end end filter.js.erb: page.replace_html 'client-not-inner', :partial => 'comments', :locals => { :com => Category.first.comments } show.html.erb (clients) <% form_tag(filter_category_path(:id), :method => :put, :class => 'categories', :remote => true, :controller => 'categoires', :action => 'filter') do %> <label>Categories</label> <%= select_tag(:category, options_for_select(Category.all.map {|category| [category.name, category.id]}, @category_id)) %> <% end %> <div class="client-note-inner"> <%= render :partial => 'comments', :locals => { :com => @comments } %> </div><!--end client-note-inner--> Hope that makes sense. Cheers.

  • Retrieve 2 last posts for each category.

    - by Savageman
    Hello, Lets say I have 2 tables: blog_posts and categories. Each blog post belongs to only ONE category, so there is basically a foreign key between the 2 tables here. I would like to retrieve the 2 lasts posts from each category, is it possible to achieve this in a single request? GROUP BY would group everything and leave me with only one row in each category. But I want 2 of them. It would be easy to perform 1 + N query (N = number of category). First retrieve the categories. And then retrieve 2 posts from each category. I believe it would also be quite easy to perform M queries (M = number of posts I want from each category). First query selects the first post for each category (with a group by). Second query retrieves the second post for each category. etc. I'm just wondering if someone has a better solution for this. I don't really mind doing 1+N queries for that, but for curiosity and general SQL knowledge, it would be appreciated! Thanks in advance to whom can help me with this.

  • assign, not toggle, category

    - by Hemal Pandya
    The Home/Categorize option in ribbon on Outlook 2010 toggles categories. If a group of mails is selected where some of the mails already have the selected category assigned then the action removes the category from those mails and assigns to the rest. I view mails grouped by conversation and would like to repeatedly assign a category to all mails in the group. I can clear all categories before assigning, but that would work only if the mails have only one category assigned. Ideally, I would like to change the behavior of the existing button. If not, a different menu option or shortcut. Is there a way to do either of this?

  • Wordpress > Custom wp-archives list by year and category with post count in sidebar

    - by David
    So I have been trying to add a custom sidebar archives section to this Wordpress Theme. I am trying to get two separate yearly archive sections, one for category A and one for category B. I need to get a post count and display it as well, to the left of "articles". This is the format I have been trying to get in the sidebar: Category 1 2010 - 5 articles 2009 - 4 articles 2008 - 6 articles 2007 - 5 articles Category 2 2010 - 8 articles 2009 - 3 articles 2008 - 7 articles 2007 - 5 articles This code is pulling the yearly archive, but the links to the yearly archives do not filter by category. However, if Category 1 does not have posts in 2008, 2008 would not show. So I feel like I am really close, but there is something wrong here in the code. I have also been unsuccessful in pulling the post count for the year/category either. Here is what I get: Category 1 2010 - articles (these links all take you to the general yearly archive page, not category specific) 2009 - articles 2007 - articles Category 2 2010 - articles 2009 - articles 2008 - articles 2007 - articles Here is are the functions I am using in my functions.php file, any idea what I am doing wrong? <?php function company_below_sidebar() { global $cat; ?> <div id="press"> <h2>Press</h2> <ul><?php $cat = '1'; wp_get_archives('type=yearly') ?></ul> </div> <div id="news"> <h2>News</h2> <ul><?php $cat = '4'; wp_get_archives('type=yearly') ?></ul> </div> <?php } add_action('thematic_betweenmainasides', 'company_below_sidebar'); function customarchives_join( $x ) { global $wpdb; return $x . " INNER JOIN $wpdb->term_relationships ON ($wpdb->posts.ID = $wpdb- >term_relationships.object_id) INNER JOIN $wpdb->term_taxonomy ON ($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)"; } function customarchives_where( $x ) { global $wpdb; global $cat; return $x . " AND $wpdb->term_taxonomy.taxonomy = 'category' AND $wpdb->term_taxonomy.term_id IN ($cat)"; } add_filter( 'getarchives_where', 'customarchives_where' ); add_filter( 'getarchives_join', 'customarchives_join' ); function company_monthly_archive_flexible($input) { // Get URL from $input preg_match('(((f|ht){1}tp://)[-a-zA-Z0-9@:%_\+.~#?&;//=]+)', $input, $matches); $url = $matches[0]; // Get content from $input (without the tags) $content = trim(strip_tags($input)); // Seperate each date element and put it in an array $dates = explode(" ", $content); // Get year $year = $dates[0]; // Customize output format $format = "<li><a href='$url'><b>$year -</b> articles</a></li>\n"; echo $format; } add_filter('get_archives_link','company_monthly_archive_flexible'); ?>

  • How do I join these queries?

    - by GregoryD
    query1: SELECT category.id, category.name, category.level, category.description, category.cat1, category.cat2, category.cat3, category.cat4, category.pri_color, category.sec_color, category.last_report AS report_id FROM category, reports_category_layout WHERE category.id = reports_category_layout.catID AND reports_category_layout.site_code = 'las' query2: SELECT DISTINCT category.id, COUNT(forum.id) AS posts, SUM(forum.view) AS views FROM category, forum WHERE category.id = forum.catID AND forum.approved = 'yes' AND forum.site_code = 'las' GROUP BY category.id query3: SELECT forum.catID, forum.title, forum.paragraph, forum.created, users.alias, forum.userID FROM forum, users, forum_cache WHERE forum.catID = forum_cache.catID AND forum.id = forum_cache.last_report AND users.id = forum.userID AND forum.approved = 'yes' Essentially, I am unsure about the syntax to join these properly. I have written a query that simply joins them, but in the case that the forum cache table contains an unapproved forum id, it will simply not return the entire row. what I really need is for query1 and query2 to be left joined on the category id, and for query 3 to be left outer joined on id = catID.

  • Context Free Language Question (Pumping Lemma)

What do you think?

  • Convert a post-order binary tree traversal index to an level-order (breadth-first) index

    - by strfry
    Assuming a complete binary tree, each node can be adressed with the position it appears in a given tree traversal algorithm. For example, the node indices of a simple complete tree with height 3 would look like this: breadth first (aka level-order): 0 / \ 1 2 / \ / \ 3 4 5 6 post-order dept first: 6 / \ 2 5 / \ / \ 0 1 3 4 The height of the tree and an index in the post-order traversal is given. How can i calculate the breadth first index from this information?

  • Get Category in Wordpress Post

    - by Adam Beaumont
    OK I have a standard post here: http://www.ticketyoda.co.uk/concerts/rihanna-tickets/rihanna-tickets-manchester-2013-06-12-united-kingdom/970 I am trying to make each post unique and contain the category information for both the city (Manchester) and the Artist (Rihanna). At the moment the box underneath the venue contains the information taken from the category (see breadcrumb). So I have 1 out of 2. What I need now is for an extra box below to show the category information for the Artist. I use : <?php $category = get_the_category(); echo $category[0]->category_description; ?> to get the first category. You can see the rihanna description under the posts here: http://www.ticketyoda.co.uk/concerts/rihanna-tickets/ Any help appreciated.

  • What is the most efficient approach to fetch category tree, products, brands, counts by subcategory

    - by alex227
    Symfony 1.4 + Doctrine 1.2. What is the best way to minimize the number of queries to retrieve products, subcategories of current category, product counts by subcategory and brand for the result set of the query below? Categories are a nested set. Here is my query: $q = Doctrine_Query::create() ->select('c.*, p.product,p.price, b.brand') ->from('Category c') ->leftJoin('c.Product p') ->leftJoin('p.Brand b') ->where ('c.root_id = ?', $this->category->getRootId()) ->andWhere('c.lft >= ?', $this->category->getLft()) ->andWhere('c.rgt <= ?', $this->category->getRgt()) ->setHydrationMode(Doctrine_Core::HYDRATE_ARRAY); $treeObject = Doctrine::getTable('Category')->getTree(); $treeObject->setBaseQuery($q); $this->treeObject = $treeObject; $treeObject->resetBaseQuery(); $this->products = $q->execute();
