• How do I add 'www' before a subdomain, like www.subdomain.domain.com?

  - by Snehal Masne

  I want to add 'www' in front of a subdomain e.g. www.subdomain.domain.com My blogs are hosted on Blogger and am using GoDaddy for having custom domains. I have HOST @ entries for 'domain' pointing specified by blogger. The following subsdomains are configured by adding CNAME alias as follows : subdomain -> ghs.google.com www -> ghs.google.com For domain (including www.domain) I have one blog. For subdomain, I am pointing it to seperate blog using above entries and 'subdomain.domain.com' works fine. I read articles on this issue and tried adding following CNAME entry but no luck : www.subdomain -> subdomain.domain.com How do I make 'www.subdomain.domain.com' work ?

• On which crowdsourced design site have you the best experience? (ie, crowdspring, mycroburst, etc)

  - by Darryl Hein

  I wasn't sure which site to ask this on (as Graphic Design hasn't reached beta yet), so I thought I would try here. I'm looking to have a couple logos and website designs done. I've had some great local designers, but each one has moved or gone else where so I keep having to look for new designers. My thought and realization in the last couple days is to go to a crowdsourced design site like crowdspring.com or mycroburst.com. Both of these sites look good, but I'm wondering what else is out there? Are there better ones and how have your experiences been them?

• User generated articles, how to do meta description?

  - by Tom Gullen

  If users submit a lot of good quality articles on the site, what is the best way to approach the meta description tag? I see two options: Have a description box and rely on them to fill it sensibly and in a good quality way Just exclude the meta description Method 1 is bad initially, but I'm willing to put time in going through and editing/checking all of them on a permanent basis. Method 2 is employed by the stack exchange site, and lets the search bots extract the best part of the page in the SERP. Thoughts? Ideas? I'm thinking a badly formed description tag is more damaging than not having one at all at the end of the day. I don't expect content to ever become unwieldy and too much to manage.

• Foundation CSS Framework, how to change triangle on accodion [migrated]

  - by CreateSean

  I'm using foundation framework for the first time and for the most part everything is going smoothly. I am however having some trouble with the accordion in that I need to change the open/close indicator triangle that is in use. You can see it in the docs here. I've looked through the css and found the section with the accordion on foundation.css at lines 709-719 but there is no image to change or adjust. I would like to change this icon to the one in my psd, but just can't figure out where. See attached screenshot for what needs to be changed. I know how to make changes, in this case I just can't find where to make the change.

• How do you organize your projects?

  - by Sergio Tapia

  Do you have any particular style of organizing projects? For example, currently I'm creating a project for a couple of schools here in Bolivia, this is how I organized it: TutoMentor (Solution) TutoMentor.UI (Winforms project) TutoMentor.Data (Class library project) How exactly do you organize your project? Do you have an example of something you organized and are proud of? Can you share a screenshot of the Solution pane? In the UI area of my application, I'm having trouble deciding on a good schema to organize different forms and where they belong. Edit: What about organizing different forms in the .UI project? Where/how should I group different form? Putting them all in root level of the project is a bad idea.

• Console keyboard input OOP

  - by Alexandre P. Levasseur

  I am trying to build a very simple console-based game with a focus on using OOP instead of procedural programming because I intend to build up on that code for more complex projects. I am wondering if there is a design pattern that nicely handles this use case: There is a Player class with a MakeMove() method interacting with the board game. The MakeMove() method has to somehow get the user input yet I do not want to code it into the Player class as this would reduce cohesion and augment coupling. I was thinking of maybe having some controller class handle the sequence of events and thus the calls to keyboard input. However, that controller class would need to be able to handle differently the subclasses of Player (e.g. the AI class does not require keyboard input). Thoughts ?

• Troubleshooting Application Timeouts in SQL Server

  - by Tara Kizer

  I recently received the following email from a blog reader: "We are having an OLTP database instance, using SQL Server 2005 with little to moderate traffic (10-20 requests/min). There are also bulk imports that occur at regular intervals in this DB and the import duration ranges between 10secs to 1 min, depending on the data size. Intermittently (2-3 times in a week), we face an issue, where queries get timed out (default of 30 secs set in application). On analyzing, we found two stored procedures, having queries with multiple table joins inside them of taking a long time (5-10 mins) in getting executed, when ideally the execution duration ranges between 5-10 secs. Execution plan of the same displayed Clustered Index Scan happening instead of Clustered Index Seek. All required Indexes are found to be present and Index fragmentation is also minimal as we Rebuild Indexes regularly alongwith Updating Statistics. With no other alternate options occuring to us, we restarted SQL server and thereafter the performance was back on track. But sometimes it was still giving timeout errors for some hits and so we also restarted IIS and that stopped the problem as of now." Rather than respond directly to the blog reader, I thought it would be more interesting to share my thoughts on this issue in a blog. There are a few things that I can think of that could cause abnormal timeouts: Blocking Bad plan in cache Outdated statistics Hardware bottleneck To determine if blocking is the issue, we can easily run sp_who/sp_who2 or a query directly on sysprocesses (select * from master..sysprocesses where blocking <> 0).  If blocking is present and consistent, then you'll need to determine whether or not to kill the parent blocking process.  Killing a process will cause the transaction to rollback, so you need to proceed with caution.  Killing the parent blocking process is only a temporary solution, so you'll need to do more thorough analysis to figure out why the blocking was present.  You should look into missing indexes and perhaps consider changing the database's isolation level to READ_COMMITTED_SNAPSHOT. The blog reader mentions that the execution plan shows a clustered index scan when a clustered index seek is normal for the stored procedure.  A clustered index scan might have been chosen either because that is what is in cache already or because of out of date statistics.  The blog reader mentions that bulk imports occur at regular intervals, so outdated statistics is definitely something that could cause this issue.  The blog reader may need to update statistics after imports are done if the imports are changing a lot of data (greater than 10%).  If the statistics are good, then the query optimizer might have chosen to scan rather than seek in a previous execution because the scan was determined to be less costly due to the value of an input parameter.  If this parameter value is rare, then its execution plan in cache is what we call a bad plan.  You want the best plan in cache for the most frequent parameter values.  If a bad plan is a recurring problem on your system, then you should consider rewriting the stored procedure.  You might want to break up the code into multiple stored procedures so that each can have a different execution plan in cache. To remove a bad plan from cache, you can recompile the stored procedure.  An alternative method is to run DBCC FREEPROCACHE which drops the procedure cache.  It is better to recompile stored procedures rather than dropping the procedure cache as dropping the procedure cache affects all plans in cache rather than just the ones that were bad, so there will be a temporary performance penalty until the plans are loaded into cache again. To determine if there is a hardware bottleneck occurring such as slow I/O or high CPU utilization, you will need to run Performance Monitor on the database server.  Hopefully you already have a baseline of the server so you know what is normal and what is not.  Be on the lookout for I/O requests taking longer than 12 milliseconds and CPU utilization over 90%.  The servers that I support typically are under 30% CPU utilization, but your baseline could be higher and be within a normal range. If restarting the SQL Server service fixes the problem, then the problem was most likely due to blocking or a bad plan in the procedure cache.  Rather than restarting the SQL Server service, which causes downtime, the blog reader should instead analyze the above mentioned things.  Proceed with caution when restarting the SQL Server service as all transactions that have not completed will be rolled back at startup.  This crash recovery process could take longer than normal if there was a long-running transaction running when the service was stopped.  Until the crash recovery process is completed on the database, it is unavailable to your applications. If restarting IIS fixes the problem, then the problem might not have been inside SQL Server.  Prior to taking this step, you should do analysis of the above mentioned things. If you can think of other reasons why the blog reader is facing this issue a few times a week, I'd love to hear your thoughts via a blog comment.

• Cannot update grub with paramters on live USB

  - by Nanne

  I have booted from a live USB ("Try Ubuntu"), that also has a persistent option set (I used LiLi to create one) to do some tests for this pcie hotplug issue I'm having. I'm trying to test some boot paramaters (like in this question) by doing this sudo nano /etc/default/grub sudo update-grub The problem is that that last command gives me this: /usr/sbin/grub-probe: error: failed to get canonical path of /cow. It looks like /cow is the file-system that is mounted on /, according to: :~# df Filesystem 1K-blocks Used Available Use% Mounted on /cow 4056896 2840204 1007284 74% / udev 1525912 4 1525908 1% /dev tmpfs 613768 844 612924 1% /run .... Is there a way for me to run update-grub?

• Protecting offline IRM rights and the error "Unable to Connect to Offline database"

  - by Simon Thorpe

  One of the most common problems I get asked about Oracle IRM is in relation to the error message "Unable to Connect to Offline database". This error message is a result of how Oracle IRM is protecting the cached rights on the local machine and if that cache has become invalid in anyway, this error is thrown. Offline rights and security First we need to understand how Oracle IRM handles offline use. The way it is implemented is one of the main reasons why Oracle IRM is the leading document security solution and demonstrates our methodology to ensure that solutions address both security and usability and puts the balance of these two in your control. Each classification has a set of predefined roles that the manager of the classification can assign to users. Each role has an offline period which determines the amount of time a user can access content without having to communicate with the IRM server. By default for the context model, which is the classification system that ships out of the box with Oracle IRM, the offline period for each role is 3 days. This is easily changed however and can be as low as under an hour to as long as years. It is also possible to switch off the ability to access content offline which can be useful when content is very sensitive and requires a tight leash. So when a user is online, transparently in the background, the Oracle IRM Desktop communicates with the server and updates the users rights and offline periods. This transparent synchronization period is determined by the server and communicated to all IRM Desktops and allows for users rights to be kept up to date without their intervention. This allows us to support some very important scenarios which are key to a successful IRM solution. A user doesn't have to make any decision when going offline, they simply unplug their laptop and they already have their offline periods synchronized to the maximum values. Any solution that requires a user to make a decision at the point of going offline isn't going to work because people forget to do this and will therefore be unable to legitimately access their content offline. If your rights change to REMOVE your access to content, this also happens in the background. This is very useful when someone has an offline duration of a week and they happen to make a connection to the internet 3 days into that offline period, the Oracle IRM Desktop detects this online state and automatically updates all rights for the user. This means the business risk is reduced when setting long offline periods, because of the daily transparent sync, you can reflect changes as soon as the user is online. Of course, if they choose not to come online at all during that week offline period, you cannot effect change, but you take that risk in giving the 7 day offline period in the first place. If you are added to a NEW classification during the day, this will automatically be synchronized without the user even having to open a piece of content secured against that classification. This is very important, consider the scenario where a senior executive downloads all their email but doesn't open any of it. Disconnects the laptop and then gets on a plane. During the flight they attempt to open a document attached to a downloaded email which has been secured against an IRM classification the user was not even aware they had access to. Because their new role in this classification was automatically synchronized their experience is a good one and the document opens. More information on how the Oracle IRM classification model works can be found in this article by Martin Abrahams. So what about problems accessing the offline rights database? So onto the core issue... when these rights are cached to your machine they are stored in an encrypted database. The encryption of this offline database is keyed to the instance of the installation of the IRM Desktop and the Windows user account. Why? Well what you do not want to happen is for someone to get their rights for content and then copy these files across hundreds of other machines, therefore getting access to sensitive content across many environments. The IRM server has a setting which controls how many times you can cache these rights on unique machines. This is because people typically access IRM content on more than one computer. Their work desktop, a laptop and often a home computer. So Oracle IRM allows for the usability of caching rights on more than one computer whilst retaining strong security over this cache. So what happens if these files are corrupted in someway? That's when you will see the error, Unable to Connect to Offline database. The most common instance of seeing this is when you are using virtual machines and copy them from one computer to the next. The virtual machine software, VMWare Workstation for example, makes changes to the unique information of that virtual machine and as such invalidates the offline database. How do you solve the problem? Resolution is however simple. You just delete all of the offline database files on the machine and they will be recreated with working encryption when the Oracle IRM Desktop next starts. However this does mean that the IRM server will think you have your rights cached to more than one computer and you will need to rerequest your rights, even though you are only going to be accessing them on one. Because it still thinks the old cache is valid. So be aware, it is good practice to increase the server limit from the default of 1 to say 3 or 4. This is done using the Enterprise Manager instance of IRM. So to delete these offline files I have a simple .bat file you can use; Download DeleteOfflineDBs.bat Note that this uses pskillto stop the irmBackground.exe from running. This is part of the IRM Desktop and holds open a lock to the offline database. Either kill this from task manager or use pskillas part of the script.

• How can I sync with an iPod Nano 6G?

  - by Martin

  I'm having no luck at all with this iPod Nano. I've tried the following software: Banshee - The iPod shows up and files seem to be copied, but they don't show up on the iPod. Rhythmbox - Same as Banshee. Claims to sync but no files available on the iPod gPodder - At first it wouldn't even recognize the device even though I set the mount point and device type. After syncing one file to the iPod from iTunes on my mac it now behaves as Banshee and Rythmbox. gtkpod - Again: Copies the files but they are inacessible on the iPod. Hipo - Doesn't even recognize the iPod Amarok - What is this, I don't even... So to summarize: After some fiddling I can get most of these apps to recognize the iPod and copy files to it, but they are not accessible on the iPod which sort of defeats the whole purpose. Help me out here. My continued harmonic love life depends on it. (Yes, it's the girlfriends iPod and laptop)

• The Presentation Secrets of Steve Jobs

  A few years go, I got interested in presentation styles after reading Cliff Atkinsons Beyond Bullet Points book.  At that time, it was obvious that the Microsoft presentation culture was kind of missing the point by having far too many bullet points. I recently picked up Carmine Gallos The Presentation Secrets of Steve Jobs.  I enjoyed this short read (238 pages) book full of presentation tips.  The best advise that I got from reading this book is that you must have an antagonist...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  A few years go, I got interested in presentation styles after reading Cliff Atkinson’s Beyond Bullet Points book.  At that time, it was obvious that the Microsoft presentation culture was kind of missing the point by having far too many bullet points. I recently picked up Carmine Gallo’s The Presentation Secrets of Steve Jobs.  I enjoyed this short read (238 pages) book full of presentation tips.  The best advise that I got from reading this book is that you must have an antagonist in your presentation.  This will help the audience visualize and understand the problem (antagonist) and the solution (what you present).  When presenting a technical topic, it is easy to forget to explain what problem is being solved by using this new technology/technique/pattern/API. This is a great read for anyone giving presentations, technical or not.     var addthis_pub="guybarrette";

• How can I resize pixel art in Pyglet without making it blurry?

  - by Renold

  I have a tileset of 8x8 pixel images, and I want to resize them in my game so they'd be double that (16x16 pixels, e.g. turning each pixel into a 2x2 block.) What I'm trying to achieve is a Minecraft-like effect, where you have small pixel images scale to larger blockier pixels. In Pyglet, the sprite's scale property blurs the pixels. Is there some other way? Update: So I changed my code, but I'm still having the same issue (nothing changed.) Of course, the GL commands are kind of mysterious to me: gl.glEnable(gl.GL_TEXTURE_2D) image = resource.image('tileset.png') texture = image.get_texture() gl.glBindTexture(gl.GL_TEXTURE_2D, texture.id) gl.glTexParameteri(gl.GL_TEXTURE_2D, gl.GL_TEXTURE_MIN_FILTER, gl.GL_NEAREST) texture.width = 16 # resize from 8x8 to 16x16 texture.height = 16 image.blit(100, 30) # draw Is there something else I should try?

• Migrate add-on domain olddomain.com to newdomain.com

  - by eHx

  I have 2 domains that are registered at GoDaddy : domaina.com (not hosted, only domain name is registered to GD) domainb.com (hosted at a different webhost, domain name registered to GD) domainb.com is an already working site, with a different webhost, but the domain name is registered to GoDaddy(and I assume the nameservers are changed to redirect to the webhost). Now, I don't understand why this was done, but domainb.com is considered a subdomain on the host... meaning the files are in a seperate folder on the server. Ex : public-html/domainb.com/public-html/FILES The structure is similar to this on the webhost : HostNAME (main root folder) domainb.com (subdomain of hostname) domainc.com (etc...) domaind.com (etc...) I want to transfer the site domainb.com to domaina.com, meaning domaina.com will become the new website, without having to re-upload all the content and CMS. The old one will redirect to domaina.com once the transfer is done (using 301 redirects). Can anyone tell me how I can do this?

• &ldquo;My life at Oracle&rdquo;

  - by cristian.condurache(at)oracle.com

  Hello everybody! My name is Eva and I currently work in Oracle Italy as Sales Programs Manager for the Technology Sales organization. Since 2009, I also proudly represent the Oracle Education Foundation within my country as the Ambassador for Italy. My career path in this amazing company began 5 years ago as a fresh graduate: after various years studying abroad, in Germany and Ireland mainly, I was looking for a valuable and concrete opportunity which could fulfill my energetic spirit. I wanted to develop myself inside a stimulating and “fast” business environment.. and here came Oracle and I really couldn’t ask for anything better!  THE PARTNER EXPERIENCE The first department I had the chance to work into was the Alliances and Channels organization, where I had the opportunity to join a brilliant team of great and visionary guys. I began having the responsibility to analyze and rationalize the portfolio of Oracle business partners and to identify potential cross-area solutions, which had to be highlighted both on the local market and internationally: this ended up with the implementation of the “Partner Community” model, a business environment of selected Oracle partners, specialized on the different technology focus areas. This new concept was then recognized as an EMEA Best Practice and replicated internationally. Having the opportunity to strengthen day after day strategic relationships with several business partners and study the market positioning of their technology solutions, I was given the role to develop the “Oracle Partner Network Innovation Award” in Italy: the EMEA competition encouraging and rewarding proven and successful technology innovations, creating high value for our common customers and generating new business potential. Several Italian partner solutions won different prizes and I decided that it was worth collecting all those valuable projects, winners and short-listed, inside two specific books in order also to provide them an international market visibility: OPN Innovation Award Booklet 2007 and OPN Innovation Award Booklet 2008 Inside the Alliances and Channels department I really had the opportunity to do    amazing things, like for example working side-by-side with one of the most exceptional teams in Oracle I have ever worked with: the EMEA Recruitment Team. Together, in fact, we conceived a brand new business initiative for our partners, called “Oracle Campus Joint Program”. This program was awarded as an EMEA Best Practice and acknowledged by both Italian public institutions and press media. Italy   is currently running its 5th edition.   Briefly, the “Oracle Campus Joint Program” aims at facing the growing issue of lack of  technology competences and skills on the market. By identifying a specific technology area and developing an intensive 4-6 week Oracle University training course and by collaborating with important academic institutes, international “gurus” and professionals, our business partners are able to benefit from a pool of brilliant top talented young consultants and offer them a significant career opportunity. BUSINESS BUT NOT ONLY: THE NO-PROFIT EXPERIENCE OF ORACLE Currently my mission in Oracle is to continue driving the implementation of strategic business development and sales programs for the entire Oracle Technology stack, involving both partners and the end-customers. But as a completely distinguished role from the day-today business, I’m also honored to represent in Italy the charity global organization founded by Oracle - the Oracle Education Foundation - and drive its corporate citizenship and marketing programs. Oracle Education Foundation is an independent charitable organization funded by Oracle and is dedicated to helping students develop 21st century skills through project learning and the use of technology. It provides “ThinkQuest” as a free program to primary and secondary (K12) schools. Just some significant numbers: today 548,000 students/teachers in 47 countries use ThinkQuest and the Oracle Education Foundation partners with 40+ no-profit or government organizations globally. ABOUT MYSELF AND MY INTERESTS About myself…I’m very enthusiastic and positive, trying always to transform difficult issues in challenging opportunities. My day usually begins very early in the morning with running, swimming or when I need to collect some “zen” energies with a yoga session or better with a long walk with my dog. I definitely love animals and generally speaking I’m very keen on environmental issues and try, as much as I can, to carry out a healthy and “planet respectful” lifestyle. My thirst for knowledge pushed me some time ago to begin a new personal challenge: I decided to enroll, dedicating a good part of my free time, for a second university degree: I chose “Neuroeconomics”, an innovative academic path which combines psychology, economics, and neuroscience and studies how people make decisions and the role of the brain when people evaluate these decisions, categorizing risks and rewards and generally interacting with each other. I’ve been very glad to talk about my experience in this article, as working for Oracle is something very stimulating. This company ensures you the opportunity to face new challenges, work with highly talented people and be professionally highlighted also globally. Motivation, good results and innovation is always pursued, recognized and fully supported. Thanks and wish you all an amazing career! If you have any question please contact [email protected].

• Certificate error with Web Platform Installer

  - by findleyd

   A friend of mine was having an issue getting the Web Platform Installer to work on his Windows Server 2008 R2 box. He said there was some sort of cert error and asked me to try https://go.microsoft.com/fwlink/?LinkId=158722 on my local machine to see if I got the cert error.  I tried it and I did get a cert error on Windows 7 64bit. I happened to notice that that url simply redirects to https://www.microsoft.com/web/webpi/2.0/WebProductList.xml . Out of curiosity I dropped to a command line and tried to run .\WebPlatformInstaller.exe /? to see if there were any command line options. It gave an error that said invalid URI. So we tried running it with the product list url like: "WebPlatformInstaller.exe https://www.microsoft.com/web/webpi/2.0/WebProductList.xml" . This seems to get around the expired cert that is on go.microsoft.com.  Here's a screen shot of the error:

• Algorithmia Source Code released on CodePlex

  - by FransBouma

  Following the release of our BCL Extensions Library on CodePlex, we have now released the source-code of Algorithmia on CodePlex! Algorithmia is an algorithm and data-structures library for .NET 3.5 or higher and is one of the pillars LLBLGen Pro v3's designer is built on. The library contains many data-structures and algorithms, and the source-code is well documented and commented, often with links to official descriptions and papers of the algorithms and data-structures implemented. The source-code is shared using Mercurial on CodePlex and is licensed under the friendly BSD2 license. User documentation is not available at the moment but will be added soon. One of the main design goals of Algorithmia was to create a library which contains implementations of well-known algorithms which weren't already implemented in .NET itself. This way, more developers out there can enjoy the results of many years of what the field of Computer Science research has delivered. Some algorithms and datastructures are known in .NET but are re-implemented because the implementation in .NET isn't efficient for many situations or lacks features. An example is the linked list in .NET: it doesn't have an O(1) concat operation, as every node refers to the containing LinkedList object it's stored in. This is bad for algorithms which rely on O(1) concat operations, like the Fibonacci heap implementation in Algorithmia. Algorithmia therefore contains a linked list with an O(1) concat feature. The following functionality is available in Algorithmia: Command, Command management. This system is usable to build a fully undo/redo aware system by building your object graph using command-aware classes. The Command pattern is implemented using a system which allows transparent undo-redo and command grouping so you can use it to make a class undo/redo aware and set properties, use its contents without using commands at all. The Commands namespace is the namespace to start. Classes you'd want to look at are CommandifiedMember, CommandifiedList and KeyedCommandifiedList. See the CommandQueueTests in the test project for examples. Graphs, Graph algorithms. Algorithmia contains a sophisticated graph class hierarchy and algorithms implemented onto them: non-directed and directed graphs, as well as a subgraph view class, which can be used to create a view onto an existing graph class which can be self-maintaining. Algorithms include transitive closure, topological sorting and others. A feature rich depth-first search (DFS) crawler is available so DFS based algorithms can be implemented quickly. All graph classes are undo/redo aware, as they can be set to be 'commandified'. When a graph is 'commandified' it will do its housekeeping through commands, which makes it fully undo-redo aware, so you can remove, add and manipulate the graph and undo/redo the activity automatically without any extra code. If you define the properties of the class you set as the vertex type using CommandifiedMember, you can manipulate the properties of vertices and the graph contents with full undo/redo functionality without any extra code. Heaps. Heaps are data-structures which have the largest or smallest item stored in them always as the 'root'. Extracting the root from the heap makes the heap determine the next in line to be the 'maximum' or 'minimum' (max-heap vs. min-heap, all heaps in Algorithmia can do both). Algorithmia contains various heaps, among them an implementation of the Fibonacci heap, one of the most efficient heap datastructures known today, especially when you want to merge different instances into one. Priority queues. Priority queues are specializations of heaps. Algorithmia contains a couple of them. Sorting. What's an algorithm library without sort algorithms? Algorithmia implements a couple of sort algorithms which sort the data in-place. This aspect is important in situations where you want to sort the elements in a buffer/list/ICollection in-place, so all data stays in the data-structure it already is stored in. PropertyBag. It re-implements Tony Allowatt's original idea in .NET 3.5 specific syntax, which is to have a generic property bag and to be able to build an object in code at runtime which can be bound to a property grid for editing. This is handy for when you have data / settings stored in XML or other format, and want to create an editable form of it without creating many editors. IEditableObject/IDataErrorInfo implementations. It contains default implementations for IEditableObject and IDataErrorInfo (EditableObjectDataContainer for IEditableObject and ErrorContainer for IDataErrorInfo), which make it very easy to implement these interfaces (just a few lines of code) without having to worry about bookkeeping during databinding. They work seamlessly with CommandifiedMember as well, so your undo/redo aware code can use them out of the box. EventThrottler. It contains an event throttler, which can be used to filter out duplicate events in an event stream coming into an observer from an event. This can greatly enhance performance in your UI without needing to do anything other than hooking it up so it's placed between the event source and your real handler. If your UI is flooded with events from data-structures observed by your UI or a middle tier, you can use this class to filter out duplicates to avoid redundant updates to UI elements or to avoid having observers choke on many redundant events. Small, handy stuff. A MultiValueDictionary, which can store multiple unique values per key, instead of one with the default Dictionary, and is also merge-aware so you can merge two into one. A Pair class, to quickly group two elements together. Multiple interfaces for helping with building a de-coupled, observer based system, and some utility extension methods for the defined data-structures. We regularly update the library with new code. If you have ideas for new algorithms or want to share your contribution, feel free to discuss it on the project's Discussions page or send us a pull request. Enjoy!

• SQL Server Denali - Serverless SQL Server

  - by simonsabin

  Who hates having to install SQL Express to get SQL Server. Anyone ever used those automatigally attached databases you can do with SQL Express. Yes! Wow you must be the only one. SQL express whilst its awesome to have a free version of SQL its a total pain to install. OK you could go with SQL Compact edition but then you lose half of your features. As part of the SQL Server Denali   feature announcements they have mentioned a new “serverless SQL Server” (Watch the video http://www.msteched.com...(read more)

• "Loading operating system... boot error" when booting from live CD

  - by jeremy

  I'm having a problem installing Ubuntu 12.10 on a new drive. I was running Windows7 on my SSD but when the drive crashed, I decided to use that as an excuse to make the switch to Ubuntu. I've been experimenting with it on my old laptop until I got my SSD replaced under warranty. Now I have my SSD back and want to install Ubuntu on my desktop machine. I used UNetbootin to make a bootable flash drive. I then I went into my BIOS and made sure USB loaded before the hard drive. However, when I try to load it I get an error that says: Loading operating system ... boot error I know the flash drive works because if I reboot my laptop or my other Windows PC with the flash drive and it loads into Ubuntu...just when I try to do it in the PC with no OS currently on the drive.

• SEO: Moving articles from one domain to another

  - by Melanie

  Currently I have articles up on a website (site A) that is not mine (but I can remove the articles.) The article's aren't faring well (not only due to the recent Google changes) but because they really could do better if I made some tweaks myself instead of relying on the domain owner's SEO skills. So I would like to set up my own website and have just my articles on it (site B.) In the past when I've moved content, I've set up redirects but this time I can't do that. What would be the best way to move the articles without having to worry about them being counted as duplicate content or any other lame stuff? Should I, A: Save the articles on my computer and remove them from Site A. Wait for Google to remove them from the index (several months.) B: Remove the articles from Site A and immediately place them on Site B.

• Do you have any “Family Feud” style questions and answers for a game for high school students?

  - by Ben Jakuben

  I am gathering questions and responses in math, science, and technology for a "Family Feud" style game for high school students. I am having trouble finding and thinking of questions, especially in the technology realm. Technology (programming or general tech) questions are preferred. If you have never seen the game show, "Family Feud" involves two teams trying to guess the most popular responses to questions asked to a group of 100 respondents. The team must guess all the popular responses to get the points for the question. For example, if the question is, "What are the major tags in HTML 4.0?", the responses might be: P (64 votes) DIV (16 votes) TABLE (8 votes) BLINK (4 votes)
