• Will uploading our .docx files on scribd and embedding the files on our website affect search engine rankings?

  - by user1439968

  We have prepared notes for university students which are on .docx format. And we want it to put on our website for viewing. We tried one option. Uploading the files on scribd and embedding it on our website for viewing on scribd viewer. Will making documents available on srcibd viewer on our website affect search engine rankings ? Will search engines treat it as duplicate content as those are already uploaded on scribd and we are embedding it on our website ? On scribd we have set the uploaded documents as 'private' though. And if it affects, can you suggest any suitable way to make .docx files to be viewed on our website that doesn't affect search engine rankings ?

• What Are the Best Ways to Get Traffic From Search Engine Optimization Consultant?

  Every internet based business needs to go through a well planned and thought out process before it actually gets established and achieving its purpose. Obviously, the process is totally different from how a brick-and-mortar business is started and established but the basics remain the same. One of the key ingredients of the process of establishing an Internet based business is getting your website search engine optimized. Depending upon the size and complexity of business, search engine optimization may turn out to be a very detailed process if you really want it to be effective and useful.

• Eval IronPython Scripts during ASP.NET Web Request; Static Engine or Not

  - by Josh Pearce

  I would like to create an ASP.NET MVC web application which has extensible logic that does not require a re-build. I was thinking of creating a filter which had an instance of the IronPython engine. What I would like to know is: how much overhead is there in creating a new engine during each web request, and would it be a better idea to keep a static engine around? However, if I were to keep a single static engine around, what are the issues I might run into as far as locking and script scope? Is it possible to have multiple scopes in the same IropPython engine so I don't get variable collision and security issues between web requests?

• Is it possible to redirect/bounce TCP traffic to external destination, base on rules?

  - by xfx

  I'm not even sure if this is possible... Also, please forgive my ignorance on the subject. What I'm looking for is for "something" that would allow me to redirect all TCP traffic arriving to host A to host B, but based on some rules. Say host A (the intermediary) receives a request (say a simple HTTP request) from a host with domain X. In that case, it lets it pass through and it's handled by host A itself. Now, let's suppose that host A receives another HTTP request from a host with domain Y, but this time, due to some customizable rules, host A redirects all the traffic to host B, and host B is able to handle it as if came directly from domain Y. And, at this point, both host B and the host with domain Y are able to freely communicate (of course, thought host A). NOTE: All these hosts are on the Internet, not inside a LAN. Please, let me know if the explanation is not clear enough.

• How to exclude one subfolder from my RewriteRule Htaccess rules?

  - by tomaszs

  I have a .htaccess in my root of website that looks like this: RewriteEngine On RewriteCond %{HTTP_HOST} !^www\.mydomain\.pl [NC] RewriteCond %{HTTP_HOST} ^(?:www\.)?([a-z0-9_-]+)\.mydomain\.pl [NC] RewriteRule ^/?$ /index.php?run=places/%1 [L,QSA] RewriteCond %{REQUEST_URI} !^/index.php$ RewriteCond %{REQUEST_URI} !^/images/ RewriteCond %{REQUEST_URI} !^/upload/ RewriteCond %{REQUEST_URI} !^/javascript/ RewriteRule ^(.*)$ /index.php?runit=$1 [L,QSA] I've installed custom guest book in folder guests and now I would like to disable rules above for this one specific folder. So that when I type: mydomain.pl/guests I would like to go normally to actual folder guests. I understand that I need to somehow disable rules above for guests subfolder, but how do I do this?

• Is there a way to disable specific Spybot Immunization rules?

  - by Iszi

  I've been having problems using a desktop sharing application, which I've traced to the Immunization protections applied via Spybot S&D. Specifically, the problem has been narrowed down to the rules in the \SOFTWARE (Plugins) categories under the Internet Explorer groups. Once I disable these Immunization categories, everything in the application works fine. Each of these categories appears to include ~900 protections on the system. I suspect that the root cause of my problems could be narrowed down to just one, or perhaps a handful, of the settings that get applied in these categories. However, I can't find any options in Spybot S&D which would allow me to drill down to the individual protection rules and choose which to enable or disable. Is there something I'm missing, or is this not a feature available via the GUI? If it's not strictly supported in the application, is there a way to work around it by manually editing some of its files or registry settings? Spybot S&D version: 2.2.21.0 Spybot Start Center version: 2.2.21.129 Windows Ultimate x64

• How to apply Outlook Junk Mail rules using Hotmail Connector?

  - by Bobb

  I use Outlook 2010 with Hotmail connector. MS says that you can sync your Outlook rules with your Hotmail but I cant see how. My actual problem is - I add a guy to my Junk blocked senders list (and I check it visually - it is in the list). But I keep receiving emails from this guy. It doesnt go to the Junk folder in Outlook. I need my Outlook to honor the rules locally at least. Is it possible?

• How can I set deadline as the I/O scheduler for USB Flash devices by using udev rules?

  - by ????

  I have set CFQ as the default I/O scheduler. I often get bad performance when I write data into a Flash device. This is resolved if I use deadline as the I/O scheduler for USB Flash devices. I can't always change the scheduler manually, right? I think writing udev rules is a good idea. Can someone please write rules for me? I want: When I plug in a USB device, detect the type of the device. If it is a portable USB hard disk, do nothing (I think if a device has more than one partitions, it always a portable hard disk. If it is a USB Flash device, set deadline as it's scheduler.

• What kind of proxy acl rules should be applied?

  - by user42891

  I try to block sites in squid based on this article. Assuming you would want to block access to Yahoo (e.g http://www.yahoo.co.jp, http://www.yahoo.com, http://www.yahoo.co.in), you would ideally want to block all of the above URLs, if I use a regular expression and try to search something called yahoo it seems to get blocked. We are just interested in applying rules which would be most commonly used across all companies (e.g. social networking sites like facebook, orkut), porn sites (e.g. sex), gaming sites (games), movie & song download sites, and sites where they can upload data (e.g. rapidshare) What would be the common set of effective rules in achieving the above?

• Why can't email clients create rules for moving dates like "yesterday"?

  - by Morgan

  I've never seen an email client that I could easily create a rule to do something like "Move messages from yesterday to a folder?" Is there some esoteric reason why this would be difficult? I know I can easily create rules around specific dates, but that isn't the same thing by a long shot; am I missing something? In Outlook 2010 I can create search folders that do sort of this type of thing, but you can't create rules around a search folder... seems like either I am missing something major, or this is terribly short-sided.

• Why are Rules not applied to additional mailboxes when using Outlook 2007 and Exchange?

  - by Clean

  Hi, I've set up a few rules in Microsoft Outlook 2007. Outlook 2007 is configured to use my Microsoft Exchange account. In the Microsoft Exchange settings, I've set up two additional mailboxes, Inbox1 and Inbox2. Thus, using Microsoft Exchange I now have three mailboxes: Inbox, Inbox1 and Inbox2. The rules I've set up all work fine for mails arriving in the Inbox. However, they do not work at all for mails arriving in either Inbox1 or Inbox2. Do anyone perhaps know why this is, and perhaps what I could to to solve this? Thanx in advance!

• Dynamic Code for type casting Generic Types 'generically' in C#

  - by Rick Strahl

  C# is a strongly typed language and while that's a fundamental feature of the language there are more and more situations where dynamic types make a lot of sense. I've written quite a bit about how I use dynamic for creating new type extensions: Dynamic Types and DynamicObject References in C# Creating a dynamic, extensible C# Expando Object Creating a dynamic DataReader for dynamic Property Access Today I want to point out an example of a much simpler usage for dynamic that I use occasionally to get around potential static typing issues in C# code especially those concerning generic types. TypeCasting Generics Generic types have been around since .NET 2.0 I've run into a number of situations in the past - especially with generic types that don't implement specific interfaces that can be cast to - where I've been unable to properly cast an object when it's passed to a method or assigned to a property. Granted often this can be a sign of bad design, but in at least some situations the code that needs to be integrated is not under my control so I have to make due with what's available or the parent object is too complex or intermingled to be easily refactored to a new usage scenario. Here's an example that I ran into in my own RazorHosting library - so I have really no excuse, but I also don't see another clean way around it in this case. A Generic Example Imagine I've implemented a generic type like this: public class RazorEngine<TBaseTemplateType> where TBaseTemplateType : RazorTemplateBase, new() You can now happily instantiate new generic versions of this type with custom template bases or even a non-generic version which is implemented like this: public class RazorEngine : RazorEngine<RazorTemplateBase> { public RazorEngine() : base() { } } To instantiate one: var engine = new RazorEngine<MyCustomRazorTemplate>(); Now imagine that the template class receives a reference to the engine when it's instantiated. This code is fired as part of the Engine pipeline when it gets ready to execute the template. It instantiates the template and assigns itself to the template: var template = new TBaseTemplateType() { Engine = this } The problem here is that possibly many variations of RazorEngine<T> can be passed. I can have RazorTemplateBase, RazorFolderHostTemplateBase, CustomRazorTemplateBase etc. as generic parameters and the Engine property has to reflect that somehow. So, how would I cast that? My first inclination was to use an interface on the engine class and then cast to the interface.  Generally that works, but unfortunately here the engine class is generic and has a few members that require the template type in the member signatures. So while I certainly can implement an interface: public interface IRazorEngine<TBaseTemplateType> it doesn't really help for passing this generically templated object to the template class - I still can't cast it if multiple differently typed versions of the generic type could be passed. I have the exact same issue in that I can't specify a 'generic' generic parameter, since there's no underlying base type that's common. In light of this I decided on using object and the following syntax for the property (and the same would be true for a method parameter): public class RazorTemplateBase :MarshalByRefObject,IDisposable { public object Engine {get;set; } } Now because the Engine property is a non-typed object, when I need to do something with this value, I still have no way to cast it explicitly. What I really would need is: public RazorEngine<> Engine { get; set; } but that's not possible. Dynamic to the Rescue Luckily with the dynamic type this sort of thing can be mitigated fairly easily. For example here's a method that uses the Engine property and uses the well known class interface by simply casting the plain object reference to dynamic and then firing away on the properties and methods of the base template class that are common to all templates:/// <summary> /// Allows rendering a dynamic template from a string template /// passing in a model. This is like rendering a partial /// but providing the input as a /// </summary> public virtual string RenderTemplate(string template,object model) { if (template == null) return string.Empty; // if there's no template markup if(!template.Contains("@")) return template; // use dynamic to get around generic type casting dynamic engine = Engine; string result = engine.RenderTemplate(template, model); if (result == null) throw new ApplicationException("RenderTemplate failed: " + engine.ErrorMessage); return result; } Prior to .NET 4.0  I would have had to use Reflection for this sort of thing which would have a been a heck of a lot more verbose, but dynamic makes this so much easier and cleaner and in this case at least the overhead is negliable since it's a single dynamic operation on an otherwise very complex operation call. Dynamic as  a Bailout Sometimes this sort of thing often reeks of a design flaw, and I agree that in hindsight this could have been designed differently. But as is often the case this particular scenario wasn't planned for originally and removing the generic signatures from the base type would break a ton of other code in the framework. Given the existing fairly complex engine design, refactoring an interface to remove generic types just to make this particular code work would have been overkill. Instead dynamic provides a nice and simple and relatively clean solution. Now if there were many other places where this occurs I would probably consider reworking the code to make this cleaner but given this isolated instance and relatively low profile operation use of dynamic seems a valid choice for me. This solution really works anywhere where you might end up with an inheritance structure that doesn't have a common base or interface that is sufficient. In the example above I know what I'm getting but there's no common base type that I can cast to. All that said, it's a good idea to think about use of dynamic before you rush in. In many situations there are alternatives that can still work with static typing. Dynamic definitely has some overhead compared to direct static access of objects, so if possible we should definitely stick to static typing. In the example above the application already uses dynamics extensively for dynamic page page templating and passing models around so introducing dynamics here has very little additional overhead. The operation itself also fires of a fairly resource heavy operation where the overhead of a couple of dynamic member accesses are not a performance issue. So, what's your experience with dynamic as a bailout mechanism? © Rick Strahl, West Wind Technologies, 2005-2012Posted in CSharp   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Spring Security - Interactive login attempt was unsuccessful

  - by Taylor L

  I've been trying to track down why Spring Security isn't creating the SPRING_SECURITY_REMEMBER_ME_COOKIE so I turned on logging for org.springframework.security.web.authentication.rememberme. At first glance, the logs make it seem like the login is failing but the login is actually successful in the sense that if I navigate to a page that requires authentication I am not redirected back to the login page. However, the logs appear to be saying the login credentials are invalid. Any ideas as to what is going on?

• Retrieve GWT radiobutton value in servlet

  Hi, I'm having a headache figuring how to retrieve the gwt Radio Buttons values in the server side. Here is my UiBinder form: <g:FormPanel ui:field="form"><g:VerticalPanel ui:field="fruitPanel"> <g:RadioButton name="fruit">apple</g:RadioButton> <g:RadioButton name="fruit">banana</g:RadioButton> <g:SubmitButton>Submit</g:SubmitButton> ... Here is how i initialize the form: form.setAction("/submit"); form.setMethod(FormPanel.METHOD_POST); So i though i would have to do this on the servlet: fruit = req.getParameter("fruit") But of course this doesn't work, parameter fruit doesn't exist :/ Edit: Ok i get parameter fruit but it's always "on" I also did try to add the radio button in java with: RadioButton rb0 = new RadioButton("fruit", "apple"); RadioButton rb1 = new RadioButton("fruit", "banana"); fruitPanel.add(rb0); fruitPanel.add(rb1); So how should i do?

• Google Datastore w/ JDO: Access Times?

• SphinxSearch or a spider - which one to choose?

  - by r2b2

  Hello, here is my problem: We own SiteA and SiteB and they share the same server and database where we have full control. SiteC , siteD and siteE are some of the sites we own as well but reside on a different web hosts. The goal is to create a unified search functionality for all of the sites mentioned above. That is if somebody search for a term in SiteA, the search result will automatically come up with results from SiteB,SiteC,SiteD and Site E too. The search results should be shown under the website they were found in. All these websites content are stored in their own databases. If I use SphinxSearch to index the above sites,I would then require those sites that we dont have complete control with to setup a web service where i can download a database dump or csv file for indexing. Im not quite sure about how a sphider will come into play here so need your opinion. Sphinx or a spider? THanks!

• GAE/Django Templates (0.96) filters to get LENGTH of GqlQuery and filter it

  - by Halst

  I pass the query with comments to my template: COMM = CommentModel.gql("ORDER BY created") doRender(self,CP.template,{'CP':CP,'COMM':COMM, 'authorize':authorize()}) And I want to output the number of comments as a result, and I try to do things like that: <a href="...">{{ COMM|length }} comments</a> Thats does not work (yeah, since COMM is GqlQuery, not a list). What can I do with that? Is there a way to convert GqlQuery to list or is there another solution? (first question) Second question is, how to filter this list in template? Is there a construct like this: <a href="...">{{ COMM|where(reference=smth)|length }} comments</a> so that I can get not only the number of all comments, but only comments with certain db.ReferenceProperty() property, for example. Last question: is it weird to do such things using templates?

• Improving CSS With .LESS

  Cascading Style Sheets, or CSS, is a syntax used to describe the look and feel of the elements in a web page. CSS allows a web developer to separate the document content - the HTML, text, and images - from the presentation of that content. Such separation makes the markup in a page easier to read, understand, and update; it can result in reduced bandwidth as the style information can be specified in a separate file and cached by the browser; and makes site-wide changes easier to apply. For a great example of the flexibility and power of CSS, check out CSS Zen Garden. This website has a single page with fixed markup, but allows web developers from around the world to submit CSS rules to define alternate presentation information. Unfortunately, certain aspects of CSS's syntax leave a bit to be desired. Many style sheets include repeated styling information because CSS does not allow the use of variables. Such repetition makes the resulting style sheet lengthier and harder to read; it results in more rules that need to be changed when the website is redesigned to use a new primary color. Specifying inherited CSS rules, such as indicating that a elements (i.e., hyperlinks) in h1 elements should not be underlined, requires creating a single selector name, like h1 a. Ideally, CSS would allow for nested rules, enabling you to define the a rules directly within the h1 rules. .LESS is a free, open-source port of Ruby's LESS library. LESS (and .LESS, by extension) is a parser that allows web developers to create style sheets using new and improved language features, including variables, operations, mixins, and nested rules. Behind the scenes, .LESS converts the enhanced CSS rules into standard CSS rules. This conversion can happen automatically and on-demand through the use of an HTTP Handler, or done manually as part of the build process.
