  • Creating an anonymous site in SharePoint 2010

    - by shehan
    Here’s how: Open up the Central Administration site and click on “Manage Web Applications” under the “Application Management” section From the ribbon click on “New” (Note: if its an existing web app, then click on “Extend”) Fill in the fields with appropriate values. Under “Security Configurations” make sure to select “Yes” for “Allow Anonymous” Click OK Once the web application has been created, a site collection would need to be created. Navigate to “Application Management” –> “Create Site Collection” Fill in the fields with the appropriate values and create the site collection Next sign into the newly created site collection as the Site Collection Administrator. From the “Site Actions” menu, select “Site Permissions” In the permissions page that loads, click on the Anonymous Access button appearing on the ribbon. A modal dialog would popup. Select the appropriate option and click OK. If you selected “Entire Web Site” its advisable to restart the browser to test anonymous access Technorati Tags: SharePoint 2010,anonymous,site collection,web application

  • Why does Google report a soft 404 when I redirect to the signup page?

    - by Hettomei
    In the last month, I've got an increased number of "soft 404" errors reported by Google webmaster tools which actually work well for users. Configuration (maybe useless): I have a website built with rails 3.1 Authentication is handled by the gem Devise Problem: On this page http://en.bemyboat.com/yacht-charter/9965-sailboat-beneteau-oceanis-43 Click on "Ask a Boat request" (a simple form, in GET to: http://en.bemyboat.com/boat_requests/new/9965) You are redirected with the HTTP status 302 to sign in You are then sent back to the new page if successfully sign in. Google tells me that the link on "ask a boat request" returns a soft 404. I can't make this form in "POST" (which will solve the problem) because we need to automatically redirect users back to the page after sign in. (the Gem Devise memorizes the "get" link.) To simplify, the question is: How to protect a private page with authentication, reached with a simple "GET" and not to be penalized by Google as a "soft 404".

  • Hyper-V for Developers - presentation from NxtGenUG Oxford (including link to more info on Dynamic M

    - by Liam Westley
    Many thanks to Richard Hopton and the NxtGenUG guys in Oxford for inviting me to talk on Hyper-V for Developers last night, and for Research Machines for providing the venue.  It was great to have developers not yet using Hyper-V who were really interested in some of the finer points to help them with specific requirements. For those wanting to follow up on the topics I covered, you can download the presentation deck as either PDF (with speaker notes included) or as the original PowerPoint slidedeck,   http://www.tigernews.co.uk/blog-twickers/nxtgenugoxford/HyperV4Devs.pdf   http://www.tigernews.co.uk/blog-twickers/nxtgenugoxford/HyperV4Devs.zip I also mentioned the new feature, Dynamic Memory, coming in Service Pack 1, had been presented in a session at TechEd 2010 by Ben Armstrong, and you can download his presentation from here,   http://blogs.msdn.com/b/virtual_pc_guy/archive/2010/06/08/talking-about-dynamic-memory.aspx

  • C# Tip - Rendering HTML in a Gridview cell

    - by BobPalmer
    Just a quick tip for working with the gridview in ASP.Net.  If your data column contains HTML text, you've probably seen something like this in your gridview after pulling the data: <font color="red">First Item</font><br/><font color="green">Second Item</font><br/><font color="blue">Third Item</font> To have the relevant column render in HTML, just go to your gridview property pages, find the column you need rendered in HTML, and click 'convert this Field into a TemplateField'.  The result is that as a template field, HTML within your bound data value will be rendered properly.  So our example above would transform into: First Item Second Item Third Item I primarily use this technique for enabling HTML content in comment fields, and to insert line breaks when building the data for these fields. Hope this helps out! -Bob

  • Dealing with blackhat SEO companies and low quality link building competitors [closed]

    - by Mikko Ohtamaa
    I have often faced a case where the competitors of my client use SEO blackhat tactics where they contact a SEO company to do link building for their websites and products. Here is an example of a typical case of a fake blog created only for link building purposes A very low content article http://marshallfab.com/fundus-camera-explained.html in obvious fake blog: no author information, partially machine generated text, all blog posts are solely about link building Following the link you get to the promoted company page http://www.patternless.com/ ... which, unsurprisingly, links the SEO company homepage in the footer text http://www.affordableseofl.com/ ... who are not shy to advertise their Extremely aggressive SEO plan Does Google have any feedback channel where one could submit cases like this, so that Google would punish the link builders? Are there any means to bring these blackhat companies to pushame to damage their reputation?

  • What is the use of Association, Aggregation and Composition (Encapsulation) in Classes

    - by SahilMahajanMj
    I have gone through lots of theories about what is encapsulation and the three techniques of implementing it, which are Association, Aggregation and Composition. What i found is, Encapsulation Encapsulation is the technique of making the fields in a class private and providing access to the fields via public methods. If a field is declared private, it cannot be accessed by anyone outside the class, thereby hiding the fields within the class. For this reason, encapsulation is also referred to as data hiding. Encapsulation can be described as a protective barrier that prevents the code and data being randomly accessed by other code defined outside the class. Access to the data and code is tightly controlled by an interface. The main benefit of encapsulation is the ability to modify our implemented code without breaking the code of others who use our code. With this feature Encapsulation gives maintainability, flexibility and extensibility to our code. Association Association is a relationship where all object have their own lifecycle and there is no owner. Let’s take an example of Teacher and Student. Multiple students can associate with single teacher and single student can associate with multiple teachers but there is no ownership between the objects and both have their own lifecycle. Both can create and delete independently. Aggregation Aggregation is a specialize form of Association where all object have their own lifecycle but there is ownership and child object can not belongs to another parent object. Let’s take an example of Department and teacher. A single teacher can not belongs to multiple departments, but if we delete the department teacher object will not destroy. We can think about “has-a” relationship. Composition Composition is again specialize form of Aggregation and we can call this as a “death” relationship. It is a strong type of Aggregation. Child object dose not have their lifecycle and if parent object deletes all child object will also be deleted. Let’s take again an example of relationship between House and rooms. House can contain multiple rooms there is no independent life of room and any room can not belongs to two different house if we delete the house room will automatically delete. The question is: Now these all are real world examples. I am looking for some description about how to use these techniques in actual class code. I mean what is the point for using three different techniques for encapsulation, How these techniques could be implemented and How to choose which technique is applicable at time.

  • What has Ubuntu contributed to the Linux Kernel?

    - by Luis Alvarado
    This question is similar to this one: What unique enhancements and features has Ubuntu brought to the Linux Community but in this case it is directed towards what has Ubuntu contributed to the official Linux Kernel. For example, many times I hear about Intel contributing to patches for the Linux Kernel like the RC6 latest patches and any other related to the recent Sandy/Ivy Bridges. In another group, Android did an upstream patch and a lot of ARM patches have also come to the Linux Kernel. I have seeing only a small percent of companies and groups that have contributed to the Linux Kernel (http://kernel.org) but I want to know, since the beginning of Ubuntu till now, what has Ubuntu contributed to the Linux Kernel in regards to any aspect of the kernel. For Kernel information I typically go to http://kernelnewbies.org and http://kernel.org

    - by Shiro
    I am looking in to Google Webmaster Tools - Crawl Error section. How should I handle for those URL due their system / application showed invalid URL. e.g http://www.example/images/products/s_=enlarge_16gb.jpg but, I dunno what happen to yahoo groups, it break the link into http://www.example/images/products/s_= enlarge_16gb.jpg and I only make the top part become hyperlink, which is http://www.example/images/products/s_= Because of the URL, Google show crawl error, I got few error because of this kind of result or because other people typo error. How do I prevent this. I am sure I don't have the right go and change other people post. What is the solution for this. Thanks!

  • Complete RESTful API debugging/testing tool

    - by vartec
    I'm looking for the most complete tool, preferably portable GUI or browser plugin to test RESTful API. What I need is: GET/POST/DELETE/PUT support multiple file uploads as fields (multipart/form-data) file uploads as body Extra points for: possibility to save multiple configurations and use them to pre-fill parameters OAuth support nice JSON response formatting Currently I'm using 3 tools: Chrome REST Console extension — My favorite, very nicely done. Has OAuth. However the functionality missing for me is sending file as a body of the request; Cannot send multiple files; Firefox Poster add-on — Quite nice, but the functionality it's missing for file as POST fields parameters; Also cannot send multiple files; cURL — can do anything, but it's quite tedious to use it from command line.

  • When to use identity comparison instead of equals?

    - by maaartinus
    I wonder why would anybody want to use identity comparison for fields in equals, like here (Java syntax): class C { private A a; public boolean equals(Object other) { // standard boring prelude if (other==this) return true; if (other==null) return false; if (other.getClass() != this.getClass()) return false; C c = (C) other; // the relevant part if (c.a != this.a) return false; // more tests... and then return true; } // getter, setters, hashCode, ... } Using == is a bit faster than equals and a bit shorter (due to no need for null tests), too, but in what cases (if any) you'd say it's really better to use == for fields inside equals?

  • Facebook Game database design

    - by facebook-100000781341887
    Hi, I'm currently develop a facebook mafia like PHP game(of course, a light weight version), here is a simplify database(MySQL) of the game id-a <int3> <for index> uid <chr15> <facebook uid> HP <int3> <health point> exp <int3> <experience> money <int3> <money> list_inventory <chr5> <the inventory user hold...some special here, talk next> ... and 20 other fields just like reputation, num of combat... *the number next to the type is the size(byte) of the type For the list_inventory, there have 40 inventorys in my game, (actually, I have 5 these kind of list in my database), and each user can only contain 1 qty of each inventory, therefore, I assign 5 char for this field and each bit of char as 1 item(5 char * 8 bit = 40 slot), and I will do some manipulation by PHP to extract the data from this 5 byte. OK, I was thinking on this, if this game contains 100,000 user, and only 10% are active, therefore, if use my method, for the space use, 5 byte * 100,000 = 500 KB if I use another method, create a table user_hold_inventory, if the user have the inventory, then insert a record into this table, so, for 10,000 active user, I assume they got all item, but for other, I assume they got no item, here is the fields of the new table id-b <int3> <for index> id-a <int3> <id of the user table> inv_no <int1> <inventory that user hold> for the space use, ([id] (3+3) byte + [inv_no] 1 byte ) * [active user] 10,000 * [all inventory] * 40 = 2.8 MB seems method 2 have use more space, but it consume less CPU power. Please comment these 2 method or please correct me if there have another better method rather than what I think. Another question is, my database contain 26 fields, but I counted 5 of them are not change frquently, should I need to separate it on the other table or not? So many words, thanks for reading :)

  • Sharing unique links on social media vs SEO

    - by MJWadmin
    We're currently implementing a voucher system on our site which will allow our users to obtain a 25+% discount on certain products, provided they donate 10% of the purchase price to charity. We will offer the ability to share the discounts via social media in return for larger discounts to the sharer for each person who clicks through the link and buys an item. I understand that social links have SEO benifits, but this appears to be based on lots of people sharing the same link. If our voucher users share a unique link i.e. http://ourdomain.com/sipsfesdf rather than a fixed link http://ourdomain.com/product-name will we still receive the same benifts? Should we instead share something like http://ourdomain.com/product-name/sipsfesdf Thanks in advance.

  • Remove Kernel 3.1

    - by chazdg
    Is there a way to remove kernel 3.1 from Oneiric? I downloaded and upgraded to 3.1 with these instructions: Open the terminal and run these two commands for both 32-bit and 64-bit versions of Ubuntu 11.10/11.04: wget http://kernel.ubuntu.com/~kernel-ppa...241006_all.deb sudo dpkg -i linux-headers-3.1.0-030100_3.1.0-030100.201110241006_all.deb Ubuntu (64-bit) For Ubuntu 11.10/11.04 (64-bit), issue these commands: wget http://kernel.ubuntu.com/~kernel-ppa...1006_amd64.deb sudo dpkg -i linux-headers-3.1.0-030100-generic_3.1.0-030100.201110241006_amd64.deb wget http://kernel.ubuntu.com/~kernel-ppa...1006_amd64.deb sudo dpkg -i linux-image-3.1.0-030100-generic_3.1.0-030100.201110241006_amd64.deb Everything went well. I was able to reboot quickly, but Firefox and Chrome constantly crash with Kernel 3.1. I am using Gnome 3.2 and saw improvement with 3.0.0.13 provided by ppa. Any help with 3.1 or just removing it would be helpful. Thanks to all that reply.

  • Subterranean IL: The ThreadLocal type

    - by Simon Cooper
    I came across ThreadLocal<T> while I was researching ConcurrentBag. To look at it, it doesn't really make much sense. What's all those extra Cn classes doing in there? Why is there a GenericHolder<T,U,V,W> class? What's going on? However, digging deeper, it's a rather ingenious solution to a tricky problem. Thread statics Declaring that a variable is thread static, that is, values assigned and read from the field is specific to the thread doing the reading, is quite easy in .NET: [ThreadStatic] private static string s_ThreadStaticField; ThreadStaticAttribute is not a pseudo-custom attribute; it is compiled as a normal attribute, but the CLR has in-built magic, activated by that attribute, to redirect accesses to the field based on the executing thread's identity. TheadStaticAttribute provides a simple solution when you want to use a single field as thread-static. What if you want to create an arbitary number of thread static variables at runtime? Thread-static fields can only be declared, and are fixed, at compile time. Prior to .NET 4, you only had one solution - thread local data slots. This is a lesser-known function of Thread that has existed since .NET 1.1: LocalDataStoreSlot threadSlot = Thread.AllocateNamedDataSlot("slot1"); string value = "foo"; Thread.SetData(threadSlot, value); string gettedValue = (string)Thread.GetData(threadSlot); Each instance of LocalStoreDataSlot mediates access to a single slot, and each slot acts like a separate thread-static field. As you can see, using thread data slots is quite cumbersome. You need to keep track of LocalDataStoreSlot objects, it's not obvious how instances of LocalDataStoreSlot correspond to individual thread-static variables, and it's not type safe. It's also relatively slow and complicated; the internal implementation consists of a whole series of classes hanging off a single thread-static field in Thread itself, using various arrays, lists, and locks for synchronization. ThreadLocal<T> is far simpler and easier to use. ThreadLocal ThreadLocal provides an abstraction around thread-static fields that allows it to be used just like any other class; it can be used as a replacement for a thread-static field, it can be used in a List<ThreadLocal<T>>, you can create as many as you need at runtime. So what does it do? It can't just have an instance-specific thread-static field, because thread-static fields have to be declared as static, and so shared between all instances of the declaring type. There's something else going on here. The values stored in instances of ThreadLocal<T> are stored in instantiations of the GenericHolder<T,U,V,W> class, which contains a single ThreadStatic field (s_value) to store the actual value. This class is then instantiated with various combinations of the Cn types for generic arguments. In .NET, each separate instantiation of a generic type has its own static state. For example, GenericHolder<int,C0,C1,C2> has a completely separate s_value field to GenericHolder<int,C1,C14,C1>. This feature is (ab)used by ThreadLocal to emulate instance thread-static fields. Every time an instance of ThreadLocal is constructed, it is assigned a unique number from the static s_currentTypeId field using Interlocked.Increment, in the FindNextTypeIndex method. The hexadecimal representation of that number then defines the specific Cn types that instantiates the GenericHolder class. That instantiation is therefore 'owned' by that instance of ThreadLocal. This gives each instance of ThreadLocal its own ThreadStatic field through a specific unique instantiation of the GenericHolder class. Although GenericHolder has four type variables, the first one is always instantiated to the type stored in the ThreadLocal<T>. This gives three free type variables, each of which can be instantiated to one of 16 types (C0 to C15). This puts an upper limit of 4096 (163) on the number of ThreadLocal<T> instances that can be created for each value of T. That is, there can be a maximum of 4096 instances of ThreadLocal<string>, and separately a maximum of 4096 instances of ThreadLocal<object>, etc. However, there is an upper limit of 16384 enforced on the total number of ThreadLocal instances in the AppDomain. This is to stop too much memory being used by thousands of instantiations of GenericHolder<T,U,V,W>, as once a type is loaded into an AppDomain it cannot be unloaded, and will continue to sit there taking up memory until the AppDomain is unloaded. The total number of ThreadLocal instances created is tracked by the ThreadLocalGlobalCounter class. So what happens when either limit is reached? Firstly, to try and stop this limit being reached, it recycles GenericHolder type indexes of ThreadLocal instances that get disposed using the s_availableIndices concurrent stack. This allows GenericHolder instantiations of disposed ThreadLocal instances to be re-used. But if there aren't any available instantiations, then ThreadLocal falls back on a standard thread local slot using TLSHolder. This makes it very important to dispose of your ThreadLocal instances if you'll be using lots of them, so the type instantiations can be recycled. The previous way of creating arbitary thread-static variables, thread data slots, was slow, clunky, and hard to use. In comparison, ThreadLocal can be used just like any other type, and each instance appears from the outside to be a non-static thread-static variable. It does this by using the CLR type system to assign each instance of ThreadLocal its own instantiated type containing a thread-static field, and so delegating a lot of the bookkeeping that thread data slots had to do to the CLR type system itself! That's a very clever use of the CLR type system.

  • JavaFX - the right way to use Properties with domain objects

    - by pjm56
    JavaFX has provided a bunch of new Property objects, such as javafx.beans.property.DoubleProperty which allow you to define fields which can be automatically observed and synchronised. In many JFX examples, the MVC model class has a number of these Property fields, which can then bind automatically to the view. However, this seems to be encouraging us to put JFX properties into our Domain objects (if you assume that the Model class is going to be a domain object), which strikes me as a poor separation of concerns (i.e. putting GUI code in the Domain). Has anyone seen this problem being solved in 'real life' and, if so, how was it done?

  • Finally found a replacement for my.live.com&hellip;

    - by eddraper
    As I had alluded to before, the transition of http://my.live.com/ to http://my.msn.com/ caused me serious grief. I've been an RSS addict for many, many years and I found the my.live.com UI to be the ultimate RSS reader and gateway to the web. It had been my home page for a long time.  My.msn has a LONG way to go before it matches the elegance and performance of my.live. The site I ended up going with is http://www.netvibes.com/ .   It’s the closest thing I could find that could do four column tiles with a reasonable amount of information density .  I’d still prefer a lot less “chrome” and better use of space, but it’s as close as I’m going to get… One feature I really do like about netvibes, is the pagination feature.  The built in feed reader is also quite nice… All-in-all, I’d recommend netvibes…

  • PanelGridLayout - A Layout Revolution

    - by Duncan Mills
    With the most recent 11.1.2 patchset (11.1.2.3) there has been a lot of excitement around ADF Essentials (and rightly so), however, in all the fuss I didn't want an even more significant change to get missed - yes you read that correctly, a more significant change! I'm talking about the new panelGridLayout component, I can confidently say that this one of the most revolutionary components that we've introduced in 11g, even though it sounds rather boring. To be totally accurate, panelGrid was introduced in 11.1.2.2 but without any presence in the component palette or other design time support, so it was largely missed unless you read the release notes. However in this latest patchset it's finally front and center. Its time to explore - we (really) need to talk about layout.  Let's face it,with ADF Faces rich client, layout is a rather arcane pursuit, once you are a layout master, all bow before you, but it's more of an art than a science, and it is often, in fact, way too difficult to achieve what should (apparently) be a pretty simple. Here's a great example, it's a homework assignment I set for folks I'm teaching this stuff to:  The requirements for this layout are: The header is 80px high, the footer is 30px. These are both fixed.  The first section of the header containing the logo is 180px wide The logo is centered within the top left hand corner of the header  The title text is start aligned in the center zone of the header and will wrap if the browser window is narrowed. It should be aligned in the center of the vertical space  The about link is anchored to the right hand side of the browser with a 20px gap and again is center aligned vertically. It will move as the browser window is reduced in width. The footer has a right aligned copyright statement, again middle aligned within a 30px high footer region and with a 20px buffer to the right hand edge. It will move as the browser window is reduced in width. All remaining space is given to a central zone, which, in this case contains a panelSplitter. Expect that at some point in time you'll need a separate messages line in the center of the footer.  In the homework assigment I set I also stipulate that no inlineStyles can be used to control alignment or margins and no use of other taglibs (e.g. JSF HTML or Trinidad HTML). So, if we take this purist approach, that basic page layout (in my stock solution) requires 3 panelStretchLayouts, 5 panelGroupLayouts and 4 spacers - not including the spacer I use for the logo and the contents of the central zone splitter - phew! The point is that even a seemingly simple layout needs a bit of thinking about, particulatly when you consider strechting and browser re-size behavior. In fact, this little sample actually teaches you much of what you need to know to become vaguely competant at layouts in the framework. The underlying result of "the way things are" is that most of us reach for panelStretchLayout before even finishing the first sip of coffee as we embark on a new page design. In fact most pages you will see in any moderately complex ADF page will basically be nested panelStretchLayouts and panelGroupLayouts, sometimes many, many levels deep. So this is a problem, we've known this for some time and now we have a good solution. (I should point out that the oft-used Trinidad trh tags are not a particularly good solution as you're tie-ing yourself to an HTML table based layout in that case with a host of attendent issues in resize and bi-di behavior, but I digress.) So, tadaaa, I give to you panelGridLayout. PanelGrid, as the name suggests takes a grid like (dare I say slightly gridbag-like) approach to layout, dividing your layout into rows and colums with margins, sizing, stretch behaviour, colspans and rowspans all rolled in, all without the use of inlineStyle. As such, it provides for a much more powerful and consise way of defining a layout such as the one above that is actually simpler and much more logical to design. The basic building blocks are the panelGridLayout itself, gridRow and gridCell. Your content sits inside the cells inside the rows, all helpfully allowing both streching, valign and halign definitions without the need to nest further panelGroupLayouts. So much simpler!  If I break down the homework example above my nested comglomorate of 12 containers and spacers can be condensed down into a single panelGrid with 3 rows and 5 cell definitions (39 lines of source reduced to 24 in the case of the sample). What's more, the actual runtime representation in the browser DOM is much, much simpler, and clean, with basically one DIV per cell (Note that just because the panelGridLayout semantics looks like an HTML table does not mean that it's rendered that way!) . Another hidden benefit is the runtime cost. Because we can use a single layout to achieve much more complex geometries the client side layout code inside the browser is having to work a lot less. This will be a real benefit if your application needs to run on lower powered clients such as netbooks or tablets. So, it's time, if you're on 11.1.2.2 or above, to smile warmly at your panelStretchLayouts, wrap the blanket around it's knees and wheel it off to the Sunset Retirement Home for a well deserved rest. There's a new kid on the block and it wants to be your friend.

  • How to install GIMP 2.7?

    - by Bucic
    Here I ask this question since Beta 2 is usable and this question would come up sooner then later ;) After issuing the standard sudo add-apt-repository ppa:matthaeus123/mrw-gimp-svn sudo apt-get update I get W: Failed to fetch http://ppa.launchpad.net/matthaeus123/mrw-gimp-svn/ubuntu/dists/precise/main/source/Sources 404 Not Found W: Failed to fetch http://ppa.launchpad.net/matthaeus123/mrw-gimp-svn/ubuntu/dists/precise/main/binary-amd64/Packages 404 Not Found W: Failed to fetch http://ppa.launchpad.net/matthaeus123/mrw-gimp-svn/ubuntu/dists /precise/main/binary-i386/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead. Is there any way to get around this. Excluding compiling from source as it usually introduces even more multilevel errors.
