  • Will a rel=canonical link pointing to a 301 redirect pass less pagerank than one without a 301?

    - by tobek
    On this official Google page about canonical links it says: Can rel="canonical" be a redirect? Yes, you can specify a URL that redirects as a canonical URL. Google will then process the redirect as usual and try to index it. There is no mention that this might dilute the impact of the canonical link. However, Google has made clear elsewhere that 301 redirects do dilute PageRank - roughly as much as a link dilutes PageRank. Is that relevant here? I'm assuming the answer is "no" but I wanted to confirm. Relevant but not duplicate: Does Rel=Canonical Pass PR from Links or Just Fix Dup Content.

  • How and what setting do you use in order to create your customized application with database? [closed]

    - by FullmetalBoy
    I have a homemade project combining with application and database. Today I'm using architecture N-tier. Totally I have 4 project in my solution in VS2010. The fourth project is a transaction layer that connect all the 3 project (one for presentation, business logic and database layer) in order to retrieve data from the database and all the way to present the data in presentation layer. Transaction layer contains entity framework 4 + customized class to carry data to the presentation layer. I always use LINQ to retrieve data in database layer. From my experience, everytime I use LINQ in relation with entity framework it always take a lot of time to retrieve data because what I believe is that my entity framework always has to reload everytime when I want to retrieve any data from the database. My question for you guys is: When you create your application connecting to a database, what architecture do you use? How do you retrieve the data from you application? Is it entity framework etc?

  • Should I have link rel=next & prev on URLs which have query variables?

    - by user21100
    For example, I have link rel prev & next set up on these pages of products: site.com?page=2 site.com?page=3 (this is my preferred structure by the way and I'm trying to get all the ugly URLs which are littered with query variables deindexed as they are causing duplicate content). So the above URLs are fine but once a filter to narrow product results is selected, like "price", the URL shows like this: site.com?price[1000-1499]=on site.com?page=2&price[1000-1499]=on As of right now, I am having the link rel prev & next dynamically added to the header of these pages but since I am working on getting these query variable URLs pages deindexed, I am wondering if I should get rid of it on these pages? Any thoughts?

  • Does a code inherit GNU GPL if it just link to GPL librrary?

    - by user14284
    Sorry for bad English. Suppose there is a library xxx under GNU GPL, that provide a function yyy. Suppose my code links to the library and use this function. Does my code inherit GPL license? IANAL, but my thoughts are conflicting: On other hand, my code is derivative from the library, so it should inherit GPL. On other hand, my code just use link to the xxx. Maybe there are other libraries, that has the same interface (particularly, they provide yyy function with same functionality, but different implementation). My code may link to any. My code really doesn't directly derived from xxx, it just use its interface. So, my code shouldn't inherit GPL. I'm confused. ADDED. The question is absolutely abstract. I don't mean any concrete GPL library.

  • Link to pages on site without .html extension appearing in browser?

    - by Anime163
    I've modified my .htaccess file to allow access to html files without having to include the extension on the end, for example: www.mysite.com/document directs to www.mysite.com/document.html However, when I want to link to pages within my site using something like <a href="page.html"></a> I still get the .html appearing in the URL. So am I allowed to exclude the extension and leave a link as <a href="page"></a> so that the extension doesn't appear in the browser? Or is there a better way to do it?

  • Question between aggregations, compositions, references (arrow) and simple link (nothing) relations within UML2 ?

    - by Rushino
    Hello, I have some questions regarding relations between aggregations, compositions, references (arrow) and simple link (nothing) relations within UML2 ? If A - B - C each have composition relationship. Are the root responsable of creation and destruction of the object B and C ? What aggregations have that the simple link or references doesn't ? What make them different ? Thanks. Edit: The question was a bit unclear and not objective. I edited it.

    - by Dano007
    Using the following html, css,jquery, js, what would be the best approach to achieving this. A visitor hits the website. The website page is displaying html and a css3 animation. The visitor is given the option to enter text freely into a text box, they enter an email address and hit send. The person receiving the message gets an email with a link, when they click the link it takes them to the webpage with the animation and the custom message their friend entered. Is this easy to achieve, what would be the best approach? anyone know of existing code I could use? Thanks

  • Disabled FRS replication on a DFS link, but the targets still list the replica set in their FRS conf

    - by Graeme Donaldson
    It's been a while since I've had to deal with the wonders of FRS, so I'm doing some testing to refresh my memory. This is what I've done so far. I am stuck with FRS rather than DFS-R for the moment since not all of my link targets are running R2. Created a domain-based DFS root, hosted on 4 servers. Created a DFS link under the root, targeted at 2 servers. The shares on both servers were empty. Dropped about 500MB of data into the target folder on one server and waited for replication to complete. Added/removed/modified files on both targets and confirmed that changes are replicated within a few seconds. Deleted the contents of the target folder on 1 server and waited for the other server to replicate the deletion. All of this worked perfectly, so now I want to remove my DFS link since I only created it for testing purposes. This is where it gets weird. I'm pretty sure that in the past I've disabled replication on the DFS link and after a short amount of time each target would log an info event in the FRS event log, something along the lines of "this server is no longer a member of replica set X". I have waited about 3 hours and I haven't seen this happen. ntfrsutl ds tells me that the server is not a member of any set, which is expected because when I disable replication on the link, the AD attributes on the computer object are removed. The weird part is... ntfrsutl sets still shows me the replica set, with all the properties, etc. So it seems like the FRS-related attributes of the target server's AD object are gone, but the FRS service for some reason hasn't removed the replica set. Can anyone see what I have done wrong?

  • Is there a browser addon to redirect a link to another, modifying some address content automatically?

    - by kokbira
    Well, I'm looking for an addon that can redirect a link when I click on it in the following ways: Change from https to http Change from twitter.com/xxxxxxxxx to, for example, dabr.co.uk/xxxxxxxxx (added at 2010-02-15th, 20:30 GMT) Remove the "?utm_source=twitterfeed&utm_medium=twitter" from the end ou a URL Generally, replace a string with another (e.g. youtube->yt; so www.example.com/visitingyoutube would become www.example.com/visitingyt) PS: (added at 2010-02-15th, 20:30 GMT) @oKtosiTe, a clearer user case: Supposes that there is a link in Twitter that point to a URL X (URL X is http://www.newspapersite.com/2011-02-15_1304.html?utm_source=twitterfeed&utm_medium=twitter) In that case, I want to open that URL only until ".html", i.e., I want to open a URL Y, that is http://www.newspapersite.com/2011-02-15_1304.html What happens when I click normally in that link: 3.1. Browser goes to URL X What I want to happen when I click in that link: 4.1. The addon must transform URL X to URL Y (I must configure it before to change a piece of URL from "?utm_source=twitterfeed&utm_medium=twitter" to "" 4.2. The browser goes to URL Y

  • OWA (Outlook Web Access) won't give user a link to attached document. Gives "Open as Web Page"

    - by Jerry Mayers
    I have been testing OWA and have found that when there is an attached file on a message it shows the "Attachments:" then the file name (but no link) and then [Open as Web Page] link. The user has to click on that which opens a new window and previews the document, then the user gets "You are currently viewing:" followed by the file name. This time the file name is a link that they can open/download. This happens for Office documents and PDF file at least. How do I make it so users can get a direct link to the file on the original message window?

  • How is route automatic metric calculated on Windows 7?

    - by e-t172
    KB299540 explains how Windows XP automatically assign metrics to IP routes: The following table outlines the criteria that is used to assign metrics for routes that are bound to network interfaces of various speeds. Greater than 200 Mb: 10 Greater than 20 Mb, and less than or equal to 200 Mb: 20 Greater than 4 Mb, and less than or equal to 20 Mb: 30 Greater than 500 kilobits (Kb), and less than or equal to 4 Mb: 40 Less than or equal to 500 Kb: 50 However, they seem to have changed their algorithm in Windows 7, as my routing table looks like this: IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 192.168.0.1 192.168.0.3 10 0.0.0.0 0.0.0.0 10.202.254.254 10.202.1.2 286 10.202.0.0 255.255.0.0 On-link 10.202.1.2 286 10.202.1.2 255.255.255.255 On-link 10.202.1.2 286 10.202.255.255 255.255.255.255 On-link 10.202.1.2 286 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 192.168.0.0 255.255.255.0 On-link 192.168.0.3 266 192.168.0.3 255.255.255.255 On-link 192.168.0.3 266 192.168.0.255 255.255.255.255 On-link 192.168.0.3 266 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 192.168.0.3 266 224.0.0.0 240.0.0.0 On-link 10.202.1.2 286 255.255.255.255 255.255.255.255 On-link 10.202.1.2 40 =========================================================================== The only "correct" metric is the first one (Gigabit connection = 10).

  • Relative path incorrect in the view layer when hosting a rails3 app in a subdirectory using passenger and apache

    - by Saifis
    I want to host multiple Rails apps on a multiple server using sub-directories. And have encountered some relative path problems. I have made a symbolic link to the app's public directory and placed it in the /var/www/html directory, var/www/html/ /test_app (symbolic link to the public folder of test_app) and set apache as so LoadModule passenger_module /usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.12/ext/apache2/mod_passenger.so PassengerRoot /usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.12 PassengerRuby /usr/local/bin/ruby <VirtualHost *:80> ServerName test.com DocumentRoot /var/www/html Options Indexes FollowSymLinks -MultiViews RailsBaseURI /test_app </Location> </VirtualHost> The links in the app itself works just fine, all the links acknowledge the test_app/ directory and work, however, when it comes to showing images in the public directory in the view, the relative path goes wrong. Say I have /system/files/1/aaa.png it goes looking for it in /var/www/html/system/files/1/aaa.png rather than /var/www/html/test_app/system/files/1/aaa.png As far as I understand this is an Apache setting problem than something to be done in Rails, if its possible I would prefer to have it contained in the conf file of apache rather than having to alter the code.

  • How do I set FireFox 10.0.7 to always open link in new tab?

    - by johnnyknew
    I am wondering if there is a way in FireFox 10.0.7 to set the it so every time I click on a link it opens it in a new tab. I went to configuration mania and options and could not find it anywhere. I also checked on the about:config and found the browser.link.open_newwindow but was unsure what to change the value to to set it so new tabs are opened every time a link is clicked on. Thanks to whomever might help.

  • How to capture a click on a link on a temporary layer that is hidden when the focus changes

    - by hstoerr
    We have a layer that appears when a certain text input has the focus and that should dissappear when the input loses the focus. I tried to do it like this: <input type="text" onblur="document.getElementById('hideme').style.display='none'" /> <div id="hideme">Textextext <a href="http://disney.com/">disney</a> text</div> My problem is: when the user clicks on the link link, the browser does not follow this link. It seems the layer disappears before the browser checks where the click goes. What can I do here? One idea would be to watch whether the mouse enters the hideme div and not to close it when the mouse cursor is in there, but this seems way to complicated. Do you have a better idea? By the way: you can try it out very easy by pasting this into the Tryit Editor of w3schools. :-)

  • How do I find the JavaScript that is invoked when I click on a button or a link in a web-page (part of a data mining project)?

    - by aste123
    I tried to use the 'inspect element' of the firebug addon for Firefox but it doesn't give me any link to the javascript. For example I got this from the firebug addon: < a href="javascript:" text of the link < /a But there is no link to the actual javascript or anything that I can use to directly go to the said link. How do I accomplish this? I need this as part of a personal data mining project that I am doing.

  • Javascipt or jQuery "Are you sure?" dialog for <A> link?

    - by Andrew Tomazos - Fathomling
    I have a link in my HTML: <a href="/DoSomethingDangerous">do something dangerous</a> Visiting the DoSomethingDangerous link causes a not easily reversable action to occur. So after the link is clicked on I would like a dialog box (eg "Are you sure?" "OK" "Cancel") to be displayed and if the user clicks Cancel the link is not visited and the browser remains at the same page. What is the cleanest technique using either Javascript or jQuery to implement this?

  • html/javascript automaticly getting link from submit button (maybe automating with python?)

    - by user317955
    I have a website where I have to click a submit button on a form. This gives me a link. I know the link is made up with the paramter that is passed through a hidden value. I was wondering if I could make a python script or something else that would go to the website and click some buttons returning the link that the submit button generates, if so how could I pass the extra parameter that influences the creation of the link? thanks in advance.

  • Are there other application layer firewalls like Microfot TMG (ISA) that do advanced http rules?

    - by Bret Fisher
    Since the old days ISA and now TMG have had several great features that I often want to deploy to my customers because of the enhanced functionality and security, but often the cost of an additinal server HW, Windows Server, and TMG license is too much to justify when compaired to a $300-500 appliance. Are there other gateway firewalls that can perform one or more of these application layer features: pre-auth incoming http traffic against AD/LDAP before sending packets to internal server (forms auth or basic creds popup)? read host headers of incoming http traffic (even on https) to a single public IP and route packets to different internal servers based on that host header?

  • How to "paint" the data layer of a CD using a CD drive?

    - by Jens
    I am looking for software to "paint" geometric shapes, dots or lines on the data layer of a writable CD (or DVD) using a standard drive. These do not have to be visible to the naked eye; I'd try to abuse the small dot size on the CD for some scientific measurements. I am aware of the "LightScribe" feature of some drives and that is not what I am looking for. Most of the software available is of course limited to write music or data, on does not offer the low-level "place a dot at this radius, this angle"-functionality. Is there something out there for me?

  • DTO or Domain Model Object in the View Layer?

    - by smayers81
    I know this is probably an age-old question, but what is the better practice? Using a domain model object throughout all layers of your application, and even binding values directly to them on the JSP (I'm using JSF). Or convert a domain model object into a DTO in the DAO or Service layer and send a lightweight DTO to the presentation layer. I have been told it makes no sense to use DTOs because changes to the database will result in changes to all your DTOs whereas using Model Objects everywhere will just require changes to the affected model object. However, the ease of use and the lightweight nature of DTOs seems to outweigh that. I should note that my app uses Hibernate Model Objects AND uses its own custom-created model objects (meaning not bound to any DB session, always detached). Is either of the above scenarios more beneficial to a strict Model Object pattern? Using Hibernate has been a huge PITA with regards to things like Lazy Initialization Exceptions.

  • Using a "local" S3 emulation layer as a replacement for HDFS?

    - by user183394
    I have been testing out the most recent Cloudera CDH4 hadoop-conf-pseudo (i.e. MRv2 or YARN) on a notebook, which has 4 cores, 8GB RAM, an Intel X25MG2 SSD, and runs a S3 emulation layer my colleagues and I wrote in C++. The OS is Ubuntu 12.04LTS 64bit. So far so good. Looking at Setting up hadoop to use S3 as a replacement for HDFS, I would like to do it on my notebook. Nevertheless, I can't find where I can change the jets3t.properties for setting the end point to localhost. I downloaded the hadoop-2.0.1-alpha.tar.gz and searched the source without finding out a clue. There is a similar Q on SO Using s3 as fs.default.name or HDFS?, but I want to use our own lightweight and fast S3 emulation layer, instead of AWS S3, for our experiments. I would appreciate a hint as to how I can change the end point to a different hostname. Regards, --Zack

  • Flex: Can I assign propertiy of multi-layer object to Chart's xField or yField?

    Hi, I have a question about how to assign property of a multi-layer object to Chart's xField or yField. For example: var obj:Object = new Object(); var store:Object = new Object(); store.store1 = 300; store.store2 = 200; store.store3 = 250; obj.date = "2010/04/26"; obj.count = 2; obj.store = store; Because I have to draw multiple LineSeries, the yField on different series must be assigned to obj.store.store1~store3. How can I set yField in different layer of object?
