  • XMPP— openfire,PHP and python web service

    - by mlakhara
    I am planning to integrate real time notifications into a web application that I am currently working on. I have decided to go with XMPP for this and selected openfire server which i thought to be suitable for my needs. The front end uses strophe library to fetch the notifications using BOSH from my openfire server. However the notices are the notifications and other messages are to be posted by my application and hence I think this code needs to reside at the backend. Initially I thougt of going with PHP XMPP libraries like XMPHP and JAXL but then I think that this would cause much overhead as each script will have to do same steps like connection, authentication etc. and I think this would make the PHP end a little slow and unresponsive. Now I am thinking of creating a middle-ware application acting as a web service that the PHP will call and this application will handle the stuff with XMPP service. The benefit with this is that this app(a server if you will) will have to connect just once and the it will sit there listening on a port. also I am planning to build it in a asynchronous way such that It will first take all the requests from my PHp app and then when there are no more requests; go about doing the notification publishing stuff. I am planninng to create this service in Python using SleekXMPP. This is just what I planned. I am new to XMPP and this whole web service stuff ans would like to take your comments on this regarding issues like memory and CPU usage, advantages, disadvantages, scalability issues,security etc. Thanks in advance. PS:-- also if something like this already exists(although I didn't find after a lot of Googling) Please direct me there. EDIT --- The middle-level service should be doing the following(but not limited to): 1. Publishing notifications for different level of groups and community pages. 2. Notification for single user on some event. 3. User registration(can be done using user service plugin though). EDIT --- Also it should like to create pub-sub nodes and subscribe and unsubscribe users from these pub-sub nodes. Also I want to store the notifications and messages in a database(openfire doesn't). Would that be a good choice?

  • Mock Objects for Unit Testing

    - by user9009
    Hello How often QA engineers are responsible for developing Mock Objects for Unit Testing. So dealing with Mock Objects is just developer job ?. The reason i ask is i'm interested in QA as my career and am learning tools like JUnit , TestNG and couple of frameworks. I just want to know until what level of unit testing is done by developer and from what point QA engineer takes over testing for better test coverage ? Thanks

  • Fair Comments

    - by Tony Davis
    To what extent is good code self-documenting? In one of the most entertaining sessions I saw at the recent PASS summit, Jeremiah Peschka (blog | twitter) got a laugh out of a sleepy post-lunch audience with the following remark: "Some developers say good code is self-documenting; I say, get off my team" I silently applauded the sentiment. It's not that all comments are useful, but that I mistrust the basic premise that "my code is so clearly written, it doesn't need any comments". I've read many pieces describing the road to self-documenting code, and my problem with most of them is that they feed the myth that comments in code are a sign of weakness. They aren't; in fact, used correctly I'd say they are essential. Regardless of how far intelligent naming can get you in describing what the code does, or how well any accompanying unit tests can explain to your fellow developers why it works that way, it's no excuse not to document fully the public interfaces to your code. Maybe I just mixed with the wrong crowd while learning my favorite language, but when I open a stored procedure I lose the will even to read it unless I see a big Phil Factor- or Jeff Moden-style header summarizing in plain English what the code does, how it fits in to the broader application, and a usage example. This public interface describes the high-level process and should explain the role of the code, clearly, for fellow developers, language non-experts, and even any non-technical stake holders in the project. When you step into the body of the code, the low-level details, then I agree that the rules are somewhat different; especially when code is subject to frequent refactoring that can quickly render comments redundant or misleading. At their worst, here, inline comments are sticking plaster to cover up the scars caused by poor naming conventions, failure in clarity when mapping a complex domain into code, or just by not entirely understanding the problem (/ this is the clever part). If you design and refactor your code carefully so that it is as simple as possible, your functions do one thing only, you avoid having two completely different algorithms in the same piece of code, and your functions, classes and variables are intelligently named, then, yes, the need for inline comments should be minimal. And yet, even given this, I'd still argue that many languages (T-SQL certainly being one) just don't lend themselves to readability when performing even moderately-complex tasks. If the algorithm is complex, I still like to see the occasional helpful comment. Please, therefore, be as liberal as you see fit in the detail of the comments you apply to this editorial, for like code it is bound to increase its' clarity and usefulness. Cheers, Tony.

  • Intel Xeon 5600 (Westmere-EP) and 7500 (Nehalem-EX)

    Intel Xeon 5600 (Westmere-EP) and 7500 (Nehalem-EX) Performance Intel launched the Xeon 5600 series (Westmere-EP, 32nm) six-core processors on 16 March 2010 without any TPC benchmark results. In the performance world, no results almost always mean bad or not good results. Yet there is every reason to believe that the Xeon 5600 series with six-cores (X models only) will performance exactly as expected for a 50% increase in the number of cores at the same frequency (as the 5500) with no system level...(read more)

  • Backup Azure Tables, schedule Azure scripts&hellip; and more

    - by Herve Roggero
    Well – months of effort are now officially over… or should I say it’s just the beginning?   Enzo Cloud Backup 2.0 (beta) is now officially out!!! This tool will let you do the following: * Backup SQL Database (and SQL Server to a limited extend) * Backup Azure Tables * Restore SQL Backups into another SQL environment * Restore Azure Tables in Azure Storage, or SQL Environment * Manage and schedule database maintenance scripts * Drop database schema containers (with preview) for SaaS environments * Receive alerts (SMTP) when operations complete or fail That’s it at a high level… but you need to see the flexibility around these features. For example you can select a specific backup strategy for Azure Tables allowing faster backup operations when partition keys use GUIDs. You can also call custom stored procedures during the restore operation of Azure Tables, allowing you to transform the data along the way. You can also set a performance threshold during Azure Table backup operations to help you control possible throttling conditions in your Storage Account. Regarding database scripts, you can now define T-SQL scripts and schedule them for execution in a specific order. You can also tell Enzo to execute a pre and post script during Azure Table restore operations against a SQL environment. The backup operation now supports backing up to multiple devices at the same time. So you can execute a backup request to both a local file, and a blob at the same time, guaranteeing that both will contain the exact same data. And due to the level of options that are available, you can save backup definitions for later reuse. The screenshot below backs up Azure Tables to two devices (a blob and a SQL Database). You can also manage your database schemas for SaaS environments that use schema containers to separate customer data. This new edition allows you to see how many objects you have in each schema, backup specific schemas, and even drop all objects in a given schema. For example the screenshot below shows that the EnzoLog database has 4 user-defined schemas, and the AFA schema has 5 tables and 1 module (stored proc, function, view…). Selecting the AFA schema and trying to delete it will prompt another screen to show which objects will be deleted. As you can see, Enzo Cloud Backup provides amazing capabilities that can help you safeguard your data in SQL Database and Azure Tables, and give you advanced management functions for your Azure environment.

  • Best advice for setting up Ubuntu on my mother's computer

    - by idealmachine
    Intended use My mother had an old Compaq desktop computer running Windows 98, which she used for occasional Web browsing and playing cards. The name of her card game is Hoyle Card Games 3. Although I had to repair it several times over the last 10 years, it worked fine until it finally died at the end of last year. Hardware specifications A relative brought up a newer computer soon afterward: Operating system: Windows XP Asus K8N motherboard (with broken on-board sound; getting a sound card) Athlon 64? processor (don't remember the clock speed) 512 MB RAM Hope the graphics card works... Replacement sound card will be one of: Ensoniq ES1370 AudioPCI Diamond Monster Sound MX300 (Aureal chipset) Sound Blaster Audigy 2 SE Peripherals HP Scanjet 3400c scanner (USB connected) HP LaserJet multi-function printer (parallel port connected, and printing works with a PCL driver) Same serial mouse as old computer Question I had set up an SSH/VNC connection to allow for remotely working out problems. Or so I thought. A month later, the computer would not boot, rendering the SSH connection useless and an OS reinstall necessary. Unfortunately, I have neither the original Windows disc nor the product key. Unless I were to pay $200 for a full Windows 7 Home Premium license for my computer, I would not be able to re-install Windows XP on hers. I consider myself an advanced Linux user, having used Debian for years. So here are my questions. I have only one day to decide whether to use Ubuntu or buy Windows: A quick search leads me to believe all the hardware listed above is supposed to work with Linux, but am I mistaken? Would Ubuntu/Xubuntu suffice (specify which one if it matters), or would I be better off paying the $200 necessary for Windows XP? Is the card game likely to run on Wine? I believe the minimum system requirement is Windows 95. Failing Wine compatibility, will VirtualBox run fast enough on such a computer (Windows 98 as the guest OS)? Are there any free card games just as good? She plays mainly Bridge, Poker, and Solitaire. Is there any "Large Fonts" option for those with poor vision? The lack of it would be a big disadvantage. BONUS: Although I would probably replace the old mouse upon a move to Ubuntu, is it even possible to get a serial mouse working?

  • Why do you like Lisp ?

    - by Geek
    Why does Paul Graham advocate Lisp? Why did ITA Software choose Lisp over other High Level languages? Lisp obviously is an advantage for the AI stuff but I don't think Lisp is any faster than Java, C# or as a matter of fact faster than C. Still it is considered as a Hackers language? I am not a master of Lisp but I find it incredibly difficult to understand the advantage one would get in writing Business Software in Lisp.

  • Friday Fun: Snow Crusher

    - by Asian Angel
    It has probably been a long week whether you have already returned to work or are finishing up the last of your vacation time. If you are in need of some stress relief, then we have we the perfect game for you. This week you get to be totally fiendish and use a monster size snowball to destroy as many cars as possible at the local snow lodge. Snow Crusher The object of the game is simple…create as large of a monster snowball as you can and then send it down over the side of the mountain to destroy the cars at the snow lodge. You can choose from three different sizes of monster snowballs to create. We chose the “Snowflake Size” for our reign of destruction. Once you have chosen a monster snowball size, all that is left to do is select the control method that works best for you. As soon as you select the control method, your monster snowball creation will automatically begin. Keep in mind that the faster your snowball goes the harder it can become to steer if you make sudden movements… At the top you can watch your progress towards the drop-off point and the green boxes highlighted at the bottom indicate how large of an item (such as trees or boulders) your snowball can roll over and add to the total mass. Snowball speed is shown in the lower right corner. Time to roll! As soon as the first green box is lit up you can start adding small trees to your snowball’s mass. You will want to avoid larger items as you go because they will penalize your score, slow you down, and reduce the size of your snowball! Halfway to the drop-off point and our snowball is now able to grab up larger trees. If you have not hit any large items along the way, your snowball will definitely be moving along at a good rate by now. When you reach the end of the mass building area, your snowball will pop out into the open and get ready to drop off over the side of the mountain. Go snowball go! Yes! Thirteen cars crushed and ready for the scrap yard… If the “Snowflake Size” snowball can do this, just think what the “Avalanche Size” can do with three minutes of time to build up mass!

  • Angry Bird Makers: Developers Love iOS Over Android To Make Money

    - by Gopinath
    These days web is buzzing with Apple iOS vs Google Android debates. Recently Fortune predicted that Android is going to explode in 2011 and it will surpass Apple’s iOS market share. Yes Android is set to spread its wings across all the devices – smartphones, TVs, set top boxes, in car entertainment devices, what not. Think of any device that requires operating system, Android can be used. On the other than iOS is only available on very selective Apple devices – iPods, iPhones and iPads. When it comes to the count of devices running on a specific OS, Android will be far ahead of iOS but when you consider a quality of devices and providing an eco system for business to make money iOS seems to be the winner. That is what experts and analysts are saysing. Here is an excerpt from Peter Vesterbacka, maker of the popular Angry Birds game, interview to Tech N Marketing site.  He says Apple will be the number one platform for a long time from a developer perspective, they have gotten so many things right. And they know what they are doing and they call the shots. Android is growing, but it’s also growing complexity at the same time. Device fragmentation not the issue, but rather the fragmentation of the ecosystem. So many different shops, so many different models. The carriers messing with the experience again. Open but not really open, a very Google centric ecosystem. And paid content just doesn’t work on Android. Peter says developer prefer iOS over Android as it’s not very easy to make money on Android market. That’s why they released a free version of Angry Birds game with ads support for Android devices. Free is the way to go with Android. Nobody has been successful selling content on Android. We will offer a way to remove the ads by paying for the app, but we don’t expect that to be a huge revenue stream.

  • SQL Server v.Next (Denali) : More on contained databases and "contained users"

    - by AaronBertrand
    One of the reasons for contained databases (see my previous post ) is to allow for a more seamless transition when moving a database from one server to another. One of the biggest complications in doing so is making sure that all of the logins are in place on the new server. Contained databases help solve this issue by creating a new type of user: a database-level user with a password. I want to stress that this is not the same concept as a user without a login , which serves a completely different...(read more)

  • My Thoughts On the Xbox 180

    - by Chris Gardner
    Originally posted on: http://geekswithblogs.net/freestylecoding/archive/2013/06/21/my-thoughts-on-the-xbox-180.aspx Everyone seems to be putting their 0.00237 cents into the wishing well over Microsoft's recent decision to reverse the DRM policy on the Xbox One. However, there have been a few issues that nobody has touched. As such, I have decided to dig 0.00237 cents out of my pocket. First, let me be clear about this point. I do not support the decision to reverse the DRM policy on the Xbox One. I wanted that point to be expressed first and unambiguously. I will say it again. I do not support the decision to reverse the DRM policy on the Xbox One. Now that I have that out of the way, let me go into my rationale. This decision removes most of the cool features that enticed me to pre-order the console. No, I didn't cancel my pre-order. There is still five months before the release of the console, and there is still a plethora of information that we, as consumers, do not have. With that, it should be noted that much of the talk in this post is speculation and rhetoric. I do not have any insider information that you do not possess. The persistent connection would have allowed the console to do many of the functions for which we have been begging. That demo where someone was playing Ryse, seamlessly accepted a multiplayer challenge in Killer Instinct, played the match (and a rematch,) and then jumped back into Ryse. That's gone, if you bought the game on disc. The new, DRM free system will require the disc in the system to play a game. That bullet point where one Xbox Live account could have up to 10 slave accounts so families could play together, no matter where they were located. That's gone as well. The promise of huge, expansive, dynamically changing worlds that was brought to us with the power of cloud computing. Well, "the people" didn't want there to be a forced, persistent connection. As such, developers can't rely on a connection and, as such, that feature is gone. This is akin to the removal of the hard drive on the Xbox 360. The list continues, but the enthusiast press has enumerated the list far better than I wish. All of this is because the Xbox team saw the HUGE success of Steam and decided to borrow a few ideas. Yes, Steam. The service that everyone hated for the first six months (for the same reasons the Xbox One is getting flack.) There was an initial growing pain. However, it is now lauded as the way games distribution should be handled. Unless you are Microsoft. I do find it curious that many of the features were originally announced for the PS4 during its unveiling. However, much of that was left strangely absent for Sony's E3 press conference. Instead, we received a single, static slide that basically said the exact opposite of Microsoft's plans. It is not farfetched to believe that slide came into existence during the approximately seven hours between the two media briefings. The thing that majorly annoys me over this whole kerfuffle is that the single thing that caused the call to arms is, really, not an issue. Microsoft never said they were going to block used sales. They said it was up to the publisher to make that decision. This would have allowed publishers to reclaim some of the costs of development in subsequent sales of the product. If you sell your game to GameStop for 7 USD, GameStop is going to sell it for 55 USD. That is 48 USD pure profit for them. Some publishers asked GameStop for a small cut. Was this a huge, money grubbing scheme? Well, yes, but the idea was that they have to handle server infrastructure for dormant accounts, etc. Of course, GameStop flatly refused, and the Online Pass was born. Fortunately, this trend didn’t last, and most publishers have stopped the practice. The ability to sell "licenses" has already begun to be challenged. Are you living in the EU? If so, companies must allow you to sell digital property. With this precedent in place, it's only a matter of time before other areas follow suit. If GameStop were smart, they should have immediately contacted every publisher out there to get the rights to become a clearing house for these licenses. Then, they keep their business model and could reduce their brick and mortar footprint. The digital landscape is changing. We need to not block this process. As Seth MacFarlane best said "Some issues are so important that you should drag people kicking and screaming." I believe this was said on an episode of Real Time with Bill Maher about the issue of Gay Marriages. Much like the original source, this is an issue that we need to drag people to the correct, progressive position. Microsoft, as a company, actually has the resources to weather the transition period. They have a great pool of first and second party developers that can leverage this new framework to prove the validity. Over time, the third party developers will get excited to use these tools. As an old C++ guy, I resisted C# for years. Now, I think it's one of the best languages I've ever used. I have a server room and a Co-Lo full of servers, so I originally didn't see the value in Azure. Now, I wish I could move every one of my projects into the cloud. I still LOVE getting physical packaging, which my music and games collection will proudly attest. However, I have started to see the value in pure digital, and have found ways to integrate this into the ways I consume those products. I can, honestly, understand how some parts of the population would be very apprehensive about this new landscape. There were valid arguments about people with no internet access. There are ways to combat these problems. These methods do not require us to throw the baby out with the bathwater. However, the number of people in the computer industry that I have seen cry foul is truly appalling. We are the forward looking people that help show how technology can improve people's lives. If we can't see the value of the brief pain involved with an exciting new ecosystem, than who will?

  • The Niantic Project: Ingress by Felicia Hajra-Lee

    Despite the current fact that the augmented reality game for Android is still in beta phase, it is amazing to see that the world of literature is already taking momentum on this 'real-life' universe. After reading 'The Alignment: Ingress' by Thomas Greanias it took only a blink of the eye to go for 'The Niantic Project: Ingress' by Felicia Hajra-Lee, too. Here is the review I posted on Amazon.com: Ingress, a parallel universe to our reality, is here. There is no doubt about this anymore... The Niantic Project, originated at the CERN collider in Geneva, Switzerland, got into focus of global players. And the game is hard; fair-play is only for the fainted ones. Felicia understands to drag the audience directly into the action of the Niantic Project and its protagonists. The novella is heavily based on the investigations posted daily on the website of Ingress. She really understands how to interweave the various clues and creates an atmosphere where it sometimes feels challenging to differentiate between fiction and reality. It all starts with 'Epiphany Night' at the Niantic Labs, the high exposure of Exotic Matter (XM) and the escape of scientist Dr. Devra Bogdanovich and 'sentinel' Roland Jarvis. Of course, a new research, or should we name it technology, like the Niantic Project has to be protected and there are multiple parties on the hunt. Throughout the various chapters Felicia introduces new potential buyers from all over the globe, gives us detailed insights on the hunters and their brutal effectiveness to finish an assignment, and manages to keep the reader in high-pitched mode thanks to a couple of turn-arounds in the overall story. Personally, I have to say that I really enjoyed reading this title. Felicia's love to details is absolutely amazing, and sometimes I was really wondering whether she would be one of the assassins. But unfortunately I also have to say that I'm not a great fan of the structural organization of the (title-less) chapters. It is fascinating to follow the ventures of Devra, Farlowe and 855 but occasionally I had to go back to previous paragraphs in order to keep track of the individual plots. Overall a great title, captivating and rich in details but simply too short. Please Fecilia, gives us more to read. As an owner of an Android smartphone or tablet, you should get yourself into the world of Ingress. Check out the Play Store to install the app. Now. ;-)

  • Engagement: Don’t Forget Your Employees!

    - by Kellsey Ruppel
    By Mark Brown, Sr. Director, Oracle WebCenter  This week we want to focus on Employee Engagement, and how it is critical to your business. Today we hear and read a great deal about “Customer Engagement” – and rightly so, it is those customers, whether they be traditional paying customers, citizens, students, club members, or whomever it is that are “paying the bills”.  A more engaged customer is more likely to make it easier to pay those bills by buying more, giving good reviews, or spreading the word of how wonderful their experience was. But what about those who are providing those services, those who design and make those goods; why is it that all too often they are left out of conversations concerning engagement? In fact, it is critical that we consider our employees as customers since they are using internal systems that run your organization the same way customers use external systems. Studies have shown that an organization in which the employees feel “engaged” or better able to make decisions, do their jobs, and are connected to their peers have better return to their stakeholders. (shareholders).  On the surface this seems obvious, happy employees are more productive employees. But it leads to the question – how many of our existing policies, systems and processes are actually reducing that level of engagement? Let’s look at a couple examples. If posting new information that may be of great value to everyone in the larger organization is hard to do because we use an antiquated system, then we’re making it hard to share and increasing the potential for duplicate work. If it is not trivially obvious how to create and publish this post, then chances are very high that I’ll put it on the bottom of my queue. And finally, when critical information is spread across various systems, intranet sites, workgroups and peoples inboxes, then it is very hard to learn and grow from that information.  These may sound trivial, but how often do we push things off not because it is intellectually challenging, we may have the answer at our fingertips, but because it is hard to make that information readily available.  If an engaged employee is a productive employee, then what can we do to increase their level of engagement? We can start by looking for opportunities to provide self-documenting self-service solutions. Our newer employees grew up using simplified web interfaces everyday and they loathe calling a help-desk unless it is the last resort. Sadly, many of our enterprise applications have not kept pace and we all still have processes that are based on sending an email -- like discount approvals, vacation requests, or even offer-letter approvals.   My suggestion is to pick one highly visible, high-impact process where employees are either reticent to execute on the process or openly complain about how cumbersome it is and look at the mechanism for that process. If there are better ways, streamlined steps, better UIs that could be done, then you have a candidate to reconfigure that process and make it more engaging. Looking to better engage your employees? Start here!

  • How To Use Regular Expressions for Data Validation and Cleanup

    You need to provide data validation at the server level for complex strings like phone numbers, email addresses, etc. You may also need to do data cleanup / standardization before moving it from source to target. Although SQL Server provides a fair number of string functions, the code developed with these built-in functions can become complex and hard to maintain or reuse.

  • Generate DROP statements for all extended properties

    - by jamiet
    This evening I have been attempting to migrate an existing on-premise database to SQL Azure using the wizard that is built-in to SQL Server Management Studio (SSMS). When I did so I received the following error: The following objects are not supported = [MS_Description] = Extended Property Evidently databases containing extended properties can not be migrated using this particular wizard so I set about removing all of the extended properties – unfortunately there were over a thousand of them so I needed a better way than simply deleting each and every one of them manually. I found a couple of resources online that went some way toward this: Drop all extended properties in a MSSQL database by Angelo Hongens Modifying and deleting extended properties by Adam Aspin Unfortunately neither provided a script that exactly suited my needs. Angelo’s covered extended properties on tables and columns however I had other objects that had extended properties on them. Adam’s looked more complete but when I ran it I got an error: Msg 468, Level 16, State 9, Line 78 Cannot resolve the collation conflict between "Latin1_General_100_CS_AS" and "Latin1_General_CI_AS" in the equal to operation. So, both great resources but I wasn’t able to use either on their own to get rid of all of my extended properties. Hence, I combined the excellent work that Angelo and Adam had provided in order to manufacture my own script which did successfully manage to generate calls to sp_dropextendedproperty for all of my extended properties. If you think you might be able to make use of such a script then feel free to download it from https://skydrive.live.com/redir.aspx?cid=550f681dad532637&resid=550F681DAD532637!16707&parid=550F681DAD532637!16706&authkey=!APxPIQCatzC7BQ8. This script will remove extended properties on tables, columns, check constraints, default constraints, views, sprocs, foreign keys, primary keys, table triggers, UDF parameters, sproc parameters, databases, schemas, database files and filegroups. If you have any object types with extended properties on them that are not in that list then consult Adam’s aforementioned article – it should prove very useful. I repeat here the message that I have placed at the top of the script: /* This script will generate calls to sp_dropextendedproperty for every extended property that exists in your database. Actually, a caveat: I don't promise that it will catch each and every extended property that exists, but I'm confident it will catch most of them! It is based on this: http://blog.hongens.nl/2010/02/25/drop-all-extended-properties-in-a-mssql-database/ by Angelo Hongens. Also had lots of help from this: http://www.sqlservercentral.com/articles/Metadata/72609/ by Adam Aspin Adam actually provides a script at that link to do something very similar but when I ran it I got an error: Msg 468, Level 16, State 9, Line 78 Cannot resolve the collation conflict between "Latin1_General_100_CS_AS" and "Latin1_General_CI_AS" in the equal to operation. So I put together this version instead. Use at your own risk. Jamie Thomson 2012-03-25 */ Hope this is useful to someone! @Jamiet

  • When to favor ASP.NET WebForms over MVC

    - by P.Brian.Mackey
    I know Microsoft has said "ASP.NET MVC is not a replacement for WebForms". Some developers say WebForms is faster to develop than MVC, but I believe this all comes down to comfort level with the technology; so I don't want any answers in this direction. Given that ASP.NET MVC gives a developer more control over our application, why is WebForms not considered obsolete? When should I favor WebForms over MVC for new development?

    - by Dave Campbell
    In this Issue: Rénald Nollet, Roboblob, Laurent Bugnion, Timmy Kokke, Michael Sync(-2-), Victor Gaudioso, and Bill Reiss. Brought to you from a tiny table in my no-tell-motelTM in 'Vegas AKA "cheaper than anywhere else" and the WiFi is free and smokin'... From SilverlightCream.com: Sync your Silverlight out-of-browser application data without service but with Dropbox Rénald Nollet is in good company (Walt Ritscher) because he's demo'ing synching OOB apps with dropbox. Unit Testable WCF Web Services in MVVM and Silverlight 4 Roboblob is discussing calling WCF Web Services from a Silverlight MVVM app... something he's been avoiding up to now. Good long code and text-filled article, with the project to download. Using commands with ApplicationBarMenuItem and ApplicationBarButton in Windows Phone 7 I almost missed this post by Laurent Bugnion, on how to get around the problem of not being able to attach commands to the ApplicationBarMenuItem and ApplicationBarButton in WP7. He gets around it with (gasp) code behind :) Introducing jLight – Talking to the DOM using Silverlight and jQuery. Oh boy... if you haven't been using jQuery yet, this should get it going for you... Timmy Kokke has produced jLight which brings jQuery into Silverlight for ease of DOM interaction... and it's on CodePlex! Test-Driven Development in Windows Phone7 – Part 1: Unit Testing with Silverlight for Phone7 Michael Sync's starting a series on TDD with Silverlight on WP7. Great tutorial and all the code is available. Tip: “Object reference not set to an instance of an object” Error in Silverlight for Windows Phone 7 Michael Sync also has a tip up for the resolution of an error we've all seen in all sorts of development, but now in WP7, and the workaround is deceptively simple. New Silverlight Video Tutorial: How to Create Gradients Victor Gaudioso has a new video tutorial up for creating gradients in Expression Blend... don't fumble around in Blend... learn from the master! Space Rocks game step 8: Hyperspace Bill Reiss is up to episode 8 in his Silverlight game series now... this latest is on Hyperspace ... don'cha wish you could just do that? My trip to 'Vegas would have been a lot faster :) Stay in the 'Light!
