• Why Does the Same Site in Different SERPs Contain and Not Contain Google Sitelinks

  - by frank13

  Is there a way to get sitelinks on a Google SERP when searching on a site's name vs. the sites' web address? Example, if you search "twin city kings", the first result is the website for Twin City Kings without sitelinks. But if you search "twincitykings.com", the first result is the website for Twin City Kings with sitelinks. Is it possible to get sitelinks on both SERPs? Thanks for helping or clarifying. Note: this question does not pertain to "how to get a sitelink". It pertains to why does the same site come up in different SERPs with and without Sitelinks.

• Trouble recovering MySQL InnoDB database after server crash

  - by Andy Shinn

  I had a server crash due to a broken iSCSI link (the filesystem went into read-only mode). After repairing the link and rebooting the machine (CentOS 5 / MySQL 5.1), the MySQL server would not start and gave the following error: 100603 19:11:46 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql InnoDB: The log sequence number in ibdata files does not match InnoDB: the log sequence number in the ib_logfiles! 100603 19:11:46 InnoDB: Database was not shut down normally!

If I try to access the data using the PHP application it crashes MySQL: `100603 19:19:19 - mysqld got signal 11 ; This could be because you hit a bug.

• Where to draw the line between development-led security and administration-led security?

  - by haylem

  There are cases where you have the opportunity, as a developer, to enforce stricter security features and protections on a software, though they could very well be managed at an environmental level (ie, the operating system would take care of it). Where would you say you draw the line, and what elements do you factor in your decision? Concrete Examples User Management is the OS's responsibility Not exactly meant as a security feature, but in a similar case Google Chrome used to not allow separate profiles. The invoked reason (though it now supports multiple profiles for a same OS user) used to be that user management was the operating system's responsibility. Disabling Web-Form Fields A recurrent request I see addressed online is to have auto-completion be disabled on form fields. Auto-completion didn't exist in old browsers, and was a welcome feature at the time it was introduced for people who needed to fill in forms often. But it also brought in some security concerns, and so some browsers started to implement, on top of the (obviously needed) setting in their own preference/customization panel, an autocomplete attribute for form or input fields. And this has now been introduced into the upcoming HTML5 standard. For browsers who do not listen to this attribute, strange hacks *\ are offered, like generating unique IDs and names for fields to avoid them from being suggested in future forms (which comes with another herd of issues, like polluting your local auto-fill cache and not preventing a password from being stored in it, but instead probably duplicating its occurences). In this particular case, and others, I'd argue that this is a user setting and that it's the user's desire and the user's responsibility to enable or disable auto-fill (by disabling the feature altogether). And if it is based on an internal policy and security requirement in a corporate environment, then substitute the user for the administrator in the above. I assume it could be counter-argued that the user may want to access non-critical applications (or sites) with this handy feature enabled, and critical applications with this feature disabled. But then I'd think that's what security zones are for (in some browsers), or the sign that you need a more secure (and dedicated) environment / account to use these applications. * I obviously don't deny the ingenuity of the people who were forced to find workarounds, just the necessity of said workarounds. Questions That was a tad long-winded, so I guess my questions are: Would you in general consider it to be the application's (hence, the developer's) responsiblity? Where do you draw the line, if not in the "general" case?

• How should I structure my urls for both SEO and localization?

  - by artlung

  When I set up a site in multiple languages, how should I set up my urls for search engines and usability? Let's say my site is www.example.com, and I'm translating into French and Spanish. What is best for usability and SEO? Directory option: http://www.example.com/sample.html http://www.example.com/fr/sample.html http://www.example.com/es/sample.html Subdomain option: http://www.example.com/sample.html http://fr.example.com/sample.html http://es.example.com/sample.html Filename option: http://www.example.com/sample.html http://www.example.com/sample.fr.html http://www.example.com/sample.es.html Accept-Language header: Or should I simply parse the Accept-Language header and generate content server-side to suit that header? Is there another way to do this? If the different language versions don't have different urls, what do I do about the search engines?

• Where and how to reference composite MVP components?

  - by Lea Hayes

  I am learning about the MVP (Model-View-Presenter) Passive View flavour of MVC. I intend to expose events from view interfaces rather than using the observer pattern to remove explicit coupling with presenter. Context: Windows Forms / Client-Side JavaScript. I am led to believe that the MVP (or indeed MVC in general) pattern can be applied at various levels of a user interface ranging from the main "Window" to an embedded "Text Field". For instance, the model to the text field is probably just a string whereas the model to the "Window" contains application specific view state (like a persons name which resides within the contained text field). Given a more complex scenario: Documentation viewer which contains: TOC navigation pane Document view Search pane Since each of these 4 user interface items are complex and can be reused elsewhere it makes sense to design these using MVP. Given that each of these user interface items comprises of 3 components; which component should be nested? where? who instantiates them? Idea #1 - Embed View inside View from Parent View public class DocumentationViewer : Form, IDocumentationViewerView { public DocumentationViewer() { ... // Unclear as to how model and presenter are injected... TocPane = new TocPaneView(); } protected ITocPaneView TocPane { get; private set; } } Idea #2 - Embed Presenter inside View from Parent View public class DocumentationViewer : Form, IDocumentationViewerView { public DocumentationViewer() { ... // This doesn't seem like view logic... var tocPaneModel = new TocPaneModel(); var tocPaneView = new TocPaneView(); TocPane = new TocPanePresenter(tocPaneModel, tocPaneView); } protected TocPanePresenter TocPane { get; private set; } } Idea #3 - Embed View inside View from Parent Presenter public class DocumentationViewer : Form, IDocumentationViewerView { ... // Part of IDocumentationViewerView: public ITocPaneView TocPane { get; set; } } public class DocumentationViewerPresenter { public DocumentationViewerPresenter(DocumentationViewerModel model, IDocumentationViewerView view) { ... var tocPaneView = new TocPaneView(); var tocPaneModel = new TocPaneModel(model.Toc); var tocPanePresenter = new TocPanePresenter(tocPaneModel, tocPaneView); view.TocPane = tocPaneView; } } Some better idea...

• Stack vs queue -based programming language efficiency [closed]

  - by Core Xii

  Suppose there are two programming languages; one where the only form of storage is one (preferred) or two (may be required for Turing-completeness) stacks, and another where the only form of storage is a single queue, with appropriate instructions in each to manipulate their respective storage to achieve Turing-completeness. Which one can more efficiently encode complex algorithms? Such that most given algorithms take less code to implement, less time to compute and less memory to do so. Also, how do they compare to a language with a traditional array (or unbounded tape, if you will) as storage?

• Getting started with Document Set in SharePoint2010

  - by ybbest

  Folders are widely used in traditional file based system, in SharePoint world you can create folder in the document library as well. However, there is a new improved feature in SharePoint called Document Set; you can attach metadata to the document set. To get start with Document set, you can perforce the following steps. 1. Go to Site Settings >>Site collection features >>Activate the Document Sets feature. 2. After the Document Sets feature is activated, you will get a new content type called Document Set. 3. Next, we can create a custom content type called Loan Application Document Set that inherited from Document Set Content Type. 4. Then I create a new column called Application Number. 5. Add this field to the loan application content type 6. Create a new Content Type called Loan Contract form that inherited from Document content type. 7. Add the Application Number to the Loan Contract form content type. 8. Create a new Content Type called Loan Application form that inherited from Document content type and add Application Number to it.(The same step as above.) 9.Go to the Loan Application Document Set content type and go to the Document Set Settings. 10. You can define which content type you would like this Document set contains and you can also define the default document for each content type. When you create a new document set, those default documents will get automatically created in the document set. You can also define the Shared field that shared across content types; in my case I define the Application number and description as my shared fields. Finally, you can define the fields that you’d like to show in the document set welcome page. 11. Now create a new document library and attach those content types to the document library and create a new loan application document set. 12. You will see the default document created in the document set.If you updated Application Number on the document set , the field will get updated in the documents inside the document set as well.

• AJAX event, prevents other page actions

  - by cobaltduck

  Here's a fairly average scenario, using JSF as an example, but this same concept I have observed in ASP.NET, Apache Wicket, and other frameworks with ajax capabilities. <h:inputText id="text1" value="#{myBacker.myBean.myStringVar}" styleClass="goodCSS"> <f:ajax event="change" listener="#{myBacker.text1ChangeEventMethod}" update="someOtherField" /> </h:inputText> <h:selectBooleanCheckbox id="check1" value="#{myBacker.myBean.myBoolVar}" /> Let's suppose that the 'text1ChangeEventListener' is essential to 'someOtherField' and perhaps toggles its disabled attribute, or changes its available options, based on the value of 'myStringVar.' The particulars aren't important, let's just accept that for some reason we need an ajax call when the 'text1' value is changed. So Jane User is working her way down the form. She arrives at the 'text1' field and types some value. The cursor focus is still in the text field, as she moves her mouse to the 'check1' box and clicks. It appears to her that nothing has happened. She clicks again, and this time the checkbox highlights and the icon indicating a selection appears in the box. Jane has to do several entries in the form today, and sees this happen every time, and it becomes very frustrating for her. Likewise, Jeff Admin is also perusing this form, and begins to type in 'text1.' He then realizes he doesn't really want to enter this data, and so moves his mouse to the "cancel" button elsewhere on the page, and clicks. Nothing seems to happen. Jeff clicks again, and after confirming he really does want to cancel, is returned to the home page. Jeff scratches his head. The problem is simply that the first thing the system does after 'text1' looses focus is run the listener and perform the ajax operation. It may only take a fraction of a second, but still, you can click other buttons all you want, but until that ajax has finished, everything else is ignored. I've spent the morning searching and reading, and it seems no one else has even noticed this. I could find not one article, blog, past question here or at SO, or anyting that addresses this obvious and glaring deficiency in ajax. So first of all, am I truly alone in thinking this is a big problem? Second, does anyone have a solution?

• are keywords in URLs good SEO or needlessly redundant?

  - by Blazemonger

  A coworker and I are locked in a debate over the value of SEO keywords in the URL of a page. She wants to change all the filenames of the HTML pages of a fencing company so they look like residential-home-chicago.html, contact-chicago-contractor.html, and so on. She is convinced that because Google highlights keywords in URLS in search results, that means that putting keywords here is more valuable. My position is that these do not improve SEO, since Google doesn't seem to give keywords in the URL any more weight than keywords in the body of the page, and might even give them less weight. In the meantime, they make it harder for me to find the pages I want when its time to edit them, and the site as a whole looks cheap and spammy. Google's own SEO guide suggests to me that yes, keywords in URLs are useful, but not superior, and that they are more useful for human readability than search engine rankings. I'm looking for authoritative sources that support either position, not blog articles from SEO optimization companies trying to promote themselves.

• Is there an RSS feed of Ubuntu Release torrent files

  - by Valorin

  A lot of torrent search engines have the ability to provide an RSS feed of matches, allowing you to set up torrent programs to download items which are published on the feed. This is useful for watching releases of things. The problem with doing this through a random search engine for Ubuntu is that you usually get too many torrents as it picks up different custom versions, and other software with the name in the title/description. See: http://www.mininova.org/rss/ubuntu So I was wondering if there was an RSS feed somewhere that only loads up the official torrent files for releases?

  It seems to me that there are a ton of <meta> tags for all sorts of different purposes out there... Though they all follow a similar format of <meta name="" content="" /> they seem to serve a vast variety of different purposes from controlling the crawling of search engine bots, providing search engine bots with descriptions of pages, to making sure a page display correctly on a mobile device. These tags fall into so many different categories I was wondering if anyone had a wiki or master list of possible meta tags and their content.

• Wordpress Installation (on IIS and SQL Server)

  - by Davide Mauri

  To proceed with the installation of Wordpress on SQL Server and IIS, first of all, you need to do the following steps Create a database on SQL Server that will be used by Wordpress Create login that can access to the just created database and put the user into ddladmin, db_datareader, db_datawriter roles Download and unpack Wordpress 3.3.2 (latest version as of 27 May 2012) zip file into a directory of your choice Download the wp-db-abstraction 1.1.4 (latest version as of 27 May 2012) plugin from wordpress.org website Now that the basic action has been done, you can start to setup and configure your Wordpress installation. Unpack and follow the instructions in the README.TXT file to install the Database Abstraction Layer. Mainly you have to: Upload wp-db-abstraction.php and the wp-db-abstraction directory to wp-content/mu-plugins.  This should be parallel to your regular plugins directory.  If the mu-plugins directory does not exist, you must create it. Put the db.php file from inside the wp-db-abstraction.php directory to wp-content/db.php Now you can create an application pool in IIS like the following one Create a website, using the above Application Pool, that points to the folder where you unpacked Wordpress files. Be sure to give the “Write” permission to the IIS account, as pointed out in this (old, but still quite valid) installation manual: http://wordpress.visitmix.com/development/installing-wordpress-on-sql-server#iis Now you’re ready to go. Point your browser to the configured website and the Wordpress installation screen will be there for you. When you’re requested to enter information to connect to MySQL database, simply skip that page, leaving the default values. If you have installed the Database Abstraction Layer, another database installation screen will appear after the one used by MySQL, and here you can enter the configuration information needed to connect to SQL Server. After having finished the installation steps, you should be able to access and navigate your wordpress site.  A final touch, and it’s done: just add the needed rewrite rules http://wordpress.visitmix.com/development/installing-wordpress-on-sql-server#urlrewrite and that’s it! Well. Not really. Unfortunately the current (as of 27 May 2012) version of the Database Abstraction Layer (1.1.4) has some bugs. Luckily they can be quickly fixed: Backslash Fix http://wordpress.org/support/topic/plugin-wp-db-abstraction-fix-problems-with-backslash-usage Select Top 0 Fix Make the change to the file “.\wp-content\mu-plugins\wp-db-abstraction\translations\sqlsrv\translations.php” suggested by “debettap”   http://sourceforge.net/tracker/?func=detail&aid=3485384&group_id=315685&atid=1328061 And now you have a 100% working Wordpress installation on SQL Server! Since I also wanted to take advantage of SQL Server Full Text Search, I’ve created a very simple wordpress plugin to setup full-text search and to use it as website search engine: http://wpfts.codeplex.com/ Enjoy!

• APT wedged by kernel version mismatch

  - by Leopd

  Apt is seemingly unable to do anything useful for me, repeatedly giving messages of this form: dpkg: dependency problems prevent configuration of linux-server: linux-server depends on linux-image-server (= 3.2.0.37.44); however: Version of linux-image-server on system is 3.2.0.37.45. linux-server depends on linux-headers-server (= 3.2.0.37.44); however: Version of linux-headers-server on system is 3.2.0.37.45. dpkg: error processing linux-server (--configure): dependency problems - leaving unconfigured This is basically the same problem as I cannot install any package (linux-image-server, linux-server dependencies errors) which got closed Duplicate to an answer that is totally useless for this situation. None of the advice in that very generic answer about dependencies helps. Explicitly: sudo apt-get clean sudo apt-get autoclean sudo apt-get update all have no not effect. While sudo apt-get -f install sudo dpkg --configure -a sudo apt-get -u dist-upgrade sudo apt-get -o Debug::pkgProblemResolver=yes dist-upgrade all give some form of the error message above.

• Keyboard "type ahead" in CRUD web apps?

  - by user61852

  In some data entry contexts, I've seen data typists, type really fast and know so well the app they use, and have a mechanic quality in their work so that they can "type ahead", ie continue typing and "tab-bing" and "enter-ing" faster than the display updates, so that in many occasions they are typing in the data for the next form before it draws itself. Then when this next entry form appears, their keystrokes fill the text boxes and they continue typing, selecting etc. In contexts like this, this speed is desirable, since this persons are really productive. I think this "type ahead of time" is only possible in desktop apps, but I may be wrong. My question is whether this way of handling the keyboard buffer (which in desktop apps require no extra programming) is achievable in web apps, or is this impossible because of the way web apps work, handle sessions, etc (network latency and the overhead of generating new web pages ) ?

• Country specific SEO

  - by John

  I have a wordpress site which is located at a .com address. The site is a simple 4 page personal site with my academic credentials, publications and a health blog that I started. I have done quite a bit of seo and I rank pretty high for the keywords i want on google.co.uk. However, I do not rank at all on google.com.mt which is the Malta specific search. I have therefore just bought the .com.mt domain and pointed the DNS nameservers to my current host provider and redirected it to the .com address. My goal is to make sure I don't screw up my google.co.uk search ranking, while starting to rank on google.com.mt I'm I doing the right thing or do you have any suggestions??

• Detecting controls of a winform

  - by Ayush Saxena

  I have a circular area cursor which is a circular winform(translucent) hooked to a cursor. On click, I want to get hold of the controls in the region of the parent winform just below the area of the cursor/form. These controls have to be arranged in circular layout on a different form. I am working on C#.NET. Please tell how to access the controls of a winform and change their positions in context with my application described above. Like what classes, procedure , resources i need. I am a newbie but desperate to complete this task.thanks in advance.

• Strategies to Defeat Memory Editors for Cheating - Desktop Games

  - by ashes999

  I'm assuming we're talking about desktop games -- something the player downloads and runs on their local computer. Many are the memory editors that allow you to detect and freeze values, like your player's health. How do you prevent cheating via memory-modifiation? What strategies are effective to combat this kind of cheating? For reference, I know that players can: - Search for something by value or range - Search for something that changed value - Set memory values - Freeze memory values I'm looking for some good ones. Two I use that are mediocre are: Displaying values as a percentage instead of the number (eg. 46/50 = 92% health) A low-level class that holds values in an array and moves them with each change. (For example, instead of an int, I have a class that's an array of ints, and whenever the value changes, I use a different, randomly-chosen array item to hold the value)

• Adding a Role to a Responsibility for Use with the Oracle E-Business Suite SDK for Java JAAS Implementation

  - by Juan Camilo Ruiz

  This new post on the series of ADF integration with Oracle E-Business Suite, was written by Sara Woodhull, Principal Product Manager on the Oracle E-Business Suite Applications Technology team. Based on a previous post of the series, a reader asked what to do if you have an existing responsibility assigned to lots of users, instead of the UMX role that the Oracle E-Business Suite SDK for Java JAAS Implementation requires.  It would be tedious to assign a new role directly to hundreds or thousands of users, so naturally we’d like to avoid that if possible. Most people don’t know this, but it’s possible to assign a UMX role to a responsibility in Oracle User Management. Once you do that, users with your responsibility will all inherit your UMX role automatically. You can then proceed with using your UMX role with JAAS for ADF. Here is how to assign a UMX role to a responsibility in Oracle E-Business Suite: In the User Management responsibility, go to the Roles & Role Inheritance page. Search for the responsibility you want. In the search results table, click the “View In Hierarchy” icon for your responsibility. Note that the codes for responsibilities start with FND_RESP, while the codes for roles start with UMX. In the Role Inheritance Hierarchy, click on the Add Node icon (green plus + ) for your responsibility. Now you will see what appears to be the same page again but it is a little different (note the text at the top telling you the role you select will be inherited…).  This time, either search or expand nodes until you find your custom UMX role.  Use the Quick Select to choose that role. You will be sent back to the first screen, where you should see a confirmation message at the top. On the same page you can verify that the custom UMX role is underneath the responsibility.  You may need to expand one or more nodes to see the UMX role under the responsibility. You might see some other roles that have been inherited as well. Now that your users have the UMX role, you can test that the UMX role is being passed through to your ADF application through the Oracle E-Business Suite SDK for Java JAAS feature. Happy coding!
