• Multitenant Design for SQL Azure: White Paper Available

  - by Herve Roggero

  Cloud computing is about scaling out all your application tiers, from web application to the database layer. In fact, the whole promise of Azure is to pay for just what you need. You need more IIS servers? No problemo... just spin another web server. You expect to double your storage needs for Azure Tables? No problemo; you are covered there too... just pay for your storage needs. But what about the database tier, SQL Azure? How do you add new databases easily, and transparently, so that your application simply uses more of SQL Azure if its needs to? Without changing a single line of code? And what if you need to scale back down? Welcome to the world of database scalability. There are many terms that describe database scalability, including data federation, multitenant designs, and even NoSQL depending on the technical solution you are implementing.  Because SQL Azure is a transactional database system, NoSQL is not really an option. However data federation and multitenant designs offer some very interesting scalability options that are worth considering. Data federation, a feature of SQL Azure that will be offered in the future, offers very interesting capabilities available natively on the SQL Azure platform. More to come in a few weeks... Multitenant designs on the other hand are design practices and technologies designed to help you reach flexible scalability options not available otherwise. The first incarnation of such a method was made available on CodePlex as an open source project (http://enzosqlshard.codeplex.com).  This project was an attempt to provide a sharding library for educational purposes.  All that sounds really cool... and really esoteric... almost a form of database "voodoo"... However after being on multiple Azure projects I am starting to see a real need. Customers want to be able to free themselves from the database tier, so that if they have 10 new customers tomorrow, all they need to do is add 2 more SQL Azure instances. It's that simple. How you achieve this, and suggested application design guidelines, are available in a white paper I just published.  The white paper offers two primary sections. The first section describes the business and technical problem at hand, and how to classify it according to specific design patterns. For example, I discuss compressed shards through schema separation. The second section offers a method for addressing the needs of a multitenant design using a new library, the big bother of the codeplex project mentioned previously (that I created earlier this year), complete with management interface and such. A Beta of this platform will be made available within weeks; as soon as the documentation will be ready.   I would like to ask you to drop me a quick email at [email protected] if you are going to download the white paper. It's not required, but it would help me get in touch with you for feedback.  You can download this white paper here:   http://www.bluesyntax.net/files/EnzoFramework.pdf . Thank you, and I am looking for feedback, thoughts and implementation opportunities.

• Reflecting on 2010 and Looking into 2011

  - by Sam Abraham

  In early 2010, I had blogged and shared my excitement as I was about to embark on a new journey relocating to South Florida.     As I settled down and adjusted to my new life, I was presented with an opportunity to get actively involved and volunteer in the local Florida .Net and Project Management communities.  I have since devoted a significant portion of my time to community initiatives, coordinating the West Palm Beach .Net User Group, volunteering as a member of the INETA Speaker’s Bureau and traveling to attend/speak at .Net code camps and user groups throughout the states of Florida and New York. I have also taken on various volunteer roles at the South Florida Chapter of the Project Management Institute starting as core team member on the chapter’s mentoring initiative and ending the year as Project Manager of the chapter’s mentoring program and as Director of Electronic Communications on the chapter’s IT team. I am also serving a one year term (2010-2011) as secretary and founding board member of Florida’s first official chapter of the International Association for Software Architects (IASA).   A big thank you is due for those who afforded me the opportunity and privilege to take part of these initiatives and those who provided guidance and encouragement when I needed them the most.   Looking ahead into 2011, I hope to continue my community involvement and volunteer activities. I will start by dedicating the first 5 weekends in the New Year to teach a free comprehensive Microsoft PowerPoint class at church. My goal will be to start from scratch and slowly cover the various available PowerPoint features that can be leveraged to create captivating presentations. Starting February, I will be resuming my user group/code camp speaking engagements at our South Florida .Net Code Camp and the West Palm Beach .Net User Group.   I look forward to continuing to meet, chat and share with our technical community members and to another active year in community service.   All the best, --Sam Abraham

• How relevant are Brainbench scores when evaluating candidates?

  - by Newtopian

  I've seen many companies using certification services such as Brainbench when evaluating candidates. Most times they use it as a secondary screen prior to interview or as a validation to choose between candidates. What is your experience with Brainbench scores? Did you try the tests yourself, and if so do you feel the score is meaningful enough to be used as part of a hiring process? Difficult choice. Consensus seems to be that BB cert are not very good as a certification. The biggest argument was around the fact that some of the questions are too precise to form a good evaluation. this view can probably be tempered somewhat but still, to hold someone's future solely on the results of this evaluation would be irresponsible. That said, I still think it is possible to use them properly to gain additional objective knowledge on a candidate's level of expertise provided the test is done in a controlled environment ensuring that all taking it stand on equal footing. Thus I went with the answer that best reflected this view keeping in mind that it is still just an hour long 50ish multiple choice question to evaluate skills and knowledge that take years to acquire. To be taken with a grain of salt ! In short, The tests have value but weather or not they are worth the money is another debate. Thanks all for your time.

• LibGdx efficient data saving/loading?

  - by grimrader22

  Currently, my LibGDX game consists of a 512 x 512 map of Tiles and entities such as players and monsters. I am wondering how to efficiently save and load the data of my levels. At the moment I am using JSON serialization for each class I want to save. I implement the Json.Serializable interface for all of these classes and write only the variables that are necessary. So my map consists of 512 x 512 tiles, that's 260,000 tiles. Each tile on the map consists of a Tile object, which points to some final Tile object like a GRASS_TILE or a STONE_TILE. When I serialize each level tile, the final Tile that it points to is re-serialized over and over again, so if I have 100 Tiles all pointing to GRASS_TILE, the data of GRASS_TILE is written 100 times over. When I go to load/deserialize my objects, 100 GrassTile objects are created, but they are each their own object. They no longer point to the final tile object. I feel like this reading/writing files very slow. If I were to abandon JSON serialization, to my knowledge my next best option would be saving the level data to a sql database. Unless there is a way to speed up serializing/deserializing 260,000 tiles I may have to do this. Is this a good idea? Could I really write that many tiles to the database efficiently? To sum all this up, I am trying to save my levels using JSON serialization, but it is VERY slow. What other options do I have for saving the data of so many tiles. I also must note that the JSON serialization is not slow on a PC, it is only VERY slow on a mobile device. Since file writing/reading is so slow on mobile devices, what can I do?

• How important is graceful degradation of JavaScript? [closed]

  - by Stephen

  Should web developers continue to spend effort progressively enhancing our web applications with JavaScript, ensuring that features gracefully degrade, thereby ensuring accessibility? Or should we spend that time focused on new features or other areas of development? The subtext of that question would be: How many of our customers/clients/users utilize our websites or applications with JavaScript disabled? Do you have any projects with requirements that specifically demand JavaScript functionality (almost all of mine do), and do those requirements also demand graceful degradation? For the sake of asking this question, I pulled up programmers.stackexchange.com without JavaScript enabled, and I was greeted with this message: "Programmers - Stack Exchange works best with JavaScript enabled". It was difficult to log in, albeit the site seemed to generally work okay. (I wasn't able to vote up any questions.) I think this is a satisfactory approach to development. Imagine the effort involved in making all of the site's features work with plain old HTML and server-side logic. On the other hand, I wonder how many users have been alienated by this approach. We've all been trained (at least the good developers among us) to use progressive enhancement and to ensure our web applications' dynamic features degrade gracefully. Is this progressive enhancement just pissing into the wind, or do some of our customers actually utilize certain web services without JavaScript enabled?

• DataContractSerializer: type is not serializable because it is not public?

  - by Michael B. McLaughlin

  I recently ran into an odd and annoying error when working with the DataContractSerializer class for a WP7 project. I thought I’d share it to save others who might encounter it the same annoyance I had. So I had an instance of  ObservableCollection<T> that I was trying to serialize (with T being a class I wrote for the project) and whenever it would hit the code to save it, it would give me: The data contract type 'ProjectName.MyMagicItemsClass' is not serializable because it is not public. Making the type public will fix this error. Alternatively, you can make it internal, and use the InternalsVisibleToAttribute attribute on your assembly in order to enable serialization of internal members - see documentation for more details. Be aware that doing so has certain security implications. This, of course, was malarkey. I was trying to write an instance of MyAwesomeClass that looked like this: [DataContract] public class MyAwesomeClass { [DataMember] public ObservableCollection<MyMagicItemsClass> GreatItems { get; set; }   [DataMember] public ObservableCollection<MyMagicItemsClass> SuperbItems { get; set; }     public MyAwesomeClass { GreatItems = new ObservableCollection<MyMagicItemsClass>(); SuperbItems = new ObservableCollection<MyMagicItemsClass>(); } }   That’s all well and fine. And MyMagicItemsClass was also public with a parameterless public constructor. It too had DataContractAttribute applied to it and it had DataMemberAttribute applied to all the properties and fields I wanted to serialize. Everything should be cool, but it’s not because I keep getting that “not public” exception. I could tell you about all the things I tried (generating a List<T> on the fly to make sure it wasn’t ObservableCollection<T>, trying to serialize the the Collections directly, moving it all to a separate library project, etc.), but I want to keep this short. In the end, I remembered my the “Debug->Exceptions…” VS menu option that brings up the list of exception-related circumstances under which the Visual Studio debugger will break. I checked the “Thrown” checkbox for “Common Language Runtime Exceptions”, started the project under the debugger, and voilà: the true problem revealed itself. Some of my properties had fairly elaborate setters whose logic I wanted to ignore. So for some of them, I applied an IgnoreDataMember attribute to them and applied the DataMember attribute to the underlying fields instead. All of which, in line with good programming practices, were private. Well, it just so happens that WP7 apps run in a “partial trust” environment and outside of “full trust”-land, DataContractSerializer refuses to serialize or deserialize non-public members. Of course that exception was swallowed up internally by .NET so all I ever saw was that bizarre message about things that I knew for certain were public being “not public”. I changed all the private fields I was serializing to public and everything worked just fine. In hindsight it all makes perfect sense. The serializer uses reflection to build up its graph of the object in order to write it out. In partial trust, you don’t want people using reflection to get at non-public members of an object since there are potential security problems with allowing that (you could break out of the sandbox pretty quickly by reflecting and calling the appropriate methods and cause some havoc by reflecting and setting the appropriate fields in certain circumstances. The fact that you cannot reflect your own assembly seems a bit heavy-handed, but then again I’m not a compiler writer or a framework designer and I have no idea what sorts of difficulties would go into allowing that from a compilation standpoint or what sorts of security problems allowing that could present (if any). So, lesson learned. If you get an incomprehensible exception message, turn on break on all thrown exceptions and try running it again (it might take a couple of tries, depending) and see what pops out. Chances are you’ll find the buried exception that actually explains what was going on. And if you’re getting a weird exception when trying to use DataContractSerializer complaining about public types not being public, chances are you’re trying to serialize a private or protected field/property.

• WordPress is now nicely supported on SQL Server (and SQL Azure for that matter)

  - by Eric Nelson

  WordPress is enormously popular for blogs and full websites thanks to an awesome eco system which has built up around it, the simplicity (relatively) of getting it up and running plus the flexibility to “bend it” in all sorts of directions. When I say bend, check out the following which are all WordPress sites My “back up blog” http://iupdateable.wordpress.com/  My groups “odd site” :) http://ubelly.com My favourite “cheap games” site http://www.frugalgaming.co.uk/  WordPress users typically run their sites on Linux and MySQL, although PHP (the language in which WordPress is written) can be happily run on Windows. Both fine technologies in their own right, but for me (and probably a fair few others) I would love to use WordPress but with the technologies I know best (aka Windows, IIS and SQL Server). However, that has proven to be actually rather tricky in practice to get working – until now. Earlier last month OmniTI released a patch for WordPress which provides SQL Server and SQL Azure support.  In parallel with that some fine folks inside Microsoft have also created http://wordpress.visitmix.com which contains information about running WordPress on the Microsoft platform with a particular focus on SQL Server and SQL Azure.  Top stuff!

• CPU Wars Is a Trump-Style Card Game Driven by Chip Stats

  - by Jason Fitzpatrick

  If you’re looking for the geekiest card game around, you’d be hard pressed to beat CPU Wars–a top-trumps card game built around CPU specs. From the game’s designers: CPU Wars is a trump card game built by geeks for geeks. For Volume 1.0 we chose 30 CPUs that we believe had the greatest impact on the desktop history. The game is ideally played by 2 or 3 people. The deck is split between the players and then each player takes a turn and picks a category that they think has the best value. We have chosen the most important specs that could be numerically represented, such as maximum speed achieved and maximum number of transistors. It’s lots of fun, it has a bit of strategy and can be played during a break or over a coffee. If you’re interested, you can pick up a copy for £7.99 (roughly $12.50 USD).

• Is Movable Type among the most secure PHP blogs? How secure are the various PHP blog applications?

  - by user6025

  Basically I'm trying to find a blog for a website, and security is the highest priority in our case. We don't need any features that I would imagine are special. Wordpress was our first idea, but its reputation precedes it, and though it may have cleaned up its act lately, I'm not seeing much solid evidence. I get the impression that Movable Type (at least the Perl version) has a much better reputation for security than Wordpress (historically at least). I'm not sure I want to take a chance with Wordpress at this point, but is there some objective source I can got to to back up (or counter) the notion that MT is at least among the best? Secunia doesn't recommend using their stats for comparisons, and securityfocus.com doesn't have stats at all that I can see. Searching here http://web.nvd.nist.gov makes MT look way better than WP (at least in 2007), but this site was referenced by MT's own page boasting about their security, so I don't know how relevant it is or how seriously people take it. Any suggestions on sites where I could/should make a somewhat objective comparison?

• Java game object pool management

  - by Kenneth Bray

  Currently I am using arrays to handle all of my game objects in the game I am making, and I know how terrible this is for performance. My question is what is the best way to handle game objects and not hurt performance? Here is how I am creating an array and then looping through it to update the objects in the array: public static ArrayList<VboCube> game_objects = new ArrayList<VboCube>(); /* add objects to the game */ while (!Display.isCloseRequested() && !Keyboard.isKeyDown(Keyboard.KEY_ESCAPE)) { for (int i = 0; i < game_objects.size(); i++){ // draw the object game_objects.get(i).Draw(); game_objects.get(i).Update(); //world.updatePhysics(); } } I am not looking for someone to write me code for asset or object management, just point me into a better direction to get better performance. I appreciate the help you guys have provided me in the past, and I dont think I would be as far along with my project without the support on stack exchange!

• Design Application to "Actively" Invite Users (pretend they have privileges)

  - by user3086451

  I am designing an application where users message one another privately, and may send messages to any Entity in the database (an Entity may not have a user account yet, it is a professional database). I am not sure how to best design the database and the API to allow messaging unregistered users. The application should remain secure, and data only accessed by those with correct permissions. Messages sent to persons without user accounts serve as an invitation. The invited person should be able to view the message, act on it, and complete the user registration upon receiving an InviteMessage. In simple terms, I have: User misc user fields (email, pw, dateJoined) Entity (large professional dataset): personalDetails... user->User (may be null) UserMessage: sender->User recipient->User dateCreated messageContent, other fields..... InviteMessage: sender->User recipient->Entity expiringUrl inviteeEmail inviteePhone I plan to alert the user when selecting a recipient that is not registered yet, and inform that he may send the message as an invitation by providing email, phone where we can send the invitation. Invitations will have a unique, one-time-use URL, e.g. uuid.uuid4(). When accessed, the invitee will see the InviteMessage and details about completing his/her registration profile. When registration is complete, InviteMessage details to a new instance of UserMessage (to not lose their data), and assign it to the newly created User. The ability to interact with and invite persons who do not yet have accounts is a key feature of the application, and it seems better to separate the invitation from the private, app messages (easier to keep functionality separate, better if data model changes). Is this a reasonable, good design? If not, what would you suggest? Do you have any improvements? Am I correct to choose to create a separate endpoint for creating invitations via the API?

• What is a generic term for name/identifier? (as opposed to label)

  - by d3vid

  I need to refer to a number of things that have both an identifier value (used in code and configuration), and a human-readable label. These things include: database columns dropdown items subapplications objects stored in a dictionary I want two unambiguous terms. One to refer to the identifier/value/key. One to refer to the label. As you can see, I'm pretty settled on the latter :) For the former, identifier seems best (not everything is strictly a key, and value and name could refer to the label; although, identifier usually refers only to a variable name), but I would prefer to follow an established practice if there is one. Is there an established term for this? (Please provide a source.) If not, are there any examples of a choice from a significant source (Java APIs, MSDN, a big FLOSS project)? (I wasn't sure if this should be posted here or to English Language & Usage. I thought this was the more appropriate expert audience. Happy to migrate if not.)

• Blocking the Apple OS X App Store

  - by Jon Rhoades

  Being the evil corporate IT overlords we need to block the new OS X App Store. As you may be aware the 10.6.6 update installs the App Store App which allows users to download and install apps without admin privileges. Some Suggestions: Don't update to 10.6.6+ Use parental controls Presumably some OD policy (if you have an OD server which we don't) Block the App store by DNS or Proxy Not updating to 10.6.6+ isn't really a long term solution as it contains security fixes and new Macs will come with it anyway. Blocking the App store at a network level doesn't solve laptop users. Ideally a simple system preference or editing of a plist that can be pushed out by ARD would be the best solution. Please note the question isn't should we block the App store, it's how we can block the App store.

• Xcode find in document stuck in case-sensitive

  - by mjdth

  When in Xcode editing code for my objective C files, I often press Command-F to bring up the little Find-In-Document banner across the top. Sometimes this gets stuck in case-sensitive search, and when it does that it also won't loop through the entire document and sometimes won't even display the selected found string. I can't find any options to turn off the case sensitivity, and I never intentionally turned it on. I've restarted xcode several times hoping that would be it but it's changed nothing. Slightly off-topic, but this was the best place I could think of to ask this question. Thanks for any response!

• How do I recover from a grub renaming issue?

  - by Justin Ardini

  I am currently dual-booting Ubuntu 10.04 and Windows 7 with grub 1.98 as the bootloader. I recently decided to edit the grub menu to remove the old Ubuntu kernels, so I followed the instructions of this guide and added the line list='version_find_latest $list' to the 10_linux file, then ran sudo update-grub. Apparently I made a mistake, because upon restart I had these bootloader entries: Ubuntu, with Linux $list Ubuntu, with Linux $list (recovery mode) Ubuntu, with Linux version_find_latest Ubuntu, with Linux version_find_latest (recovery mode) When I try to load any of these, I get a grub error along the lines of, Error: not a normal file Now I can't start any version of Ubuntu to remove the line I added. What's the best course of action to be able to use Ubuntu again? Thanks.

  I'm not sure what happened here, but let me give you the rundown. I have a CRM 2011 IFD that by all accounts was functioning. Out of nowhere, I find that when being redirected to ADFS 2.0 login page by CRM, instead of seeing the login page, I get the following error: 403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied. I'm not sure what is going on here. The certs are good, as best as I can tell, the logins are good. More specifically, nothing has been modified. This all worked just fine, and now it doesn't. I'm really stumped.

• Prevent mail flagged as spam when switching mail servers (new SPF records)?

  - by Jakobud

  For our business, we send out a significant amount of newsletter alerts to customers that sign up for it on our website. We used to send this mail directly from our web server via PHP. But because the web server limited us to the number of emails we could send per day, we purchased a VM server at a different host (that doesn't throttle email) and we are going to use that account solely for sending out the emails. Anyways, now that the SPF records are going to be different from what they used to be and the source mail server is different, what steps need to be taken to prevent these emails being flagged as spam? I know in Gmail, it's pretty smart about determining if the person actually sending the email is sending it from the server it expects (for flagging Phishing emails, etc). We don't want that to happen to our emails. Just sending a couple test emails out, Gmail's shows the SPF record saying: Authentication-Results: mx.google.com; spf=neutral (google.com: XXX.XXX.23.176 is neither permitted nor denied by best guess record for domain of [email protected]) [email protected] So is there anything we need to do with regards to SPF records as we move forward?

• I'm confused about encryption and SSL

  - by ChowKiko

  while my friends and I planning to run our own website, we're confused about the encryption where hackers can TAPPING or in social engineering it's WIRE TAPPING, but I don't know how do they call it in Computers today... Well guys, I just want to know how encryption works with websites if we are using PHP+MYSQL? Is it ok to use user login ---- (PHP) encrypt inputted value then (PHP) will decrypt and validate it going to (MySQL) user login ---- (PHP) encrypt inputted value and decrypt the (MySQL) data if they are similar... Is it similar if we use $_SESSION without encryption inside PHP going to MySQL?or PHP encryption also helps the manipulation of binaries?..I'm so confused T_T... In regards to what I stated above, can a hacker hook the data if the server uses $_SESSION? Is $_SESSION safe?... IF THE HACKER CAN HOOK it? is it necessary to use SSL on our website? and why do some Merchandise websites use SSL and likewise facebook also uses SSL? what is the best suit for you if there is no SSL? encrypting the DATA using PHP going to MySQL or even without encryption while the PHP server uses $_SESSION?...

• Reboot VPS by reaching memory limit

  - by Ali

  When a server uses memory more than available RAM, the system will shut down the virtual machine. Then, it is only possible to boot from outside (VPS control panel, e.g. vePortal or SolusVM). However, it should be possible to plan a reboot before possible shut down. What is the best practical method to check the used memory, and reboot the system upon reaching e.g. 90% of the allowed RAM? Is there a common program or script to do so? I am using Debian/Ubuntu.

• MacBook Pro - 72k vs 54k rpm drives - Heat and Noise

  - by webworm

  I am looking at a new 15" MacBook Pro for development purposes. I am planning to run a Virtual Machine for about 50% of my work (Windows 7 x64, IIS, SQL Server, and VS 2010). The upgrade from a 54000 rpm drive to a 72000 rpm is only $45. From what I understand the faster rotational speed of the 72000 rpm drive will help virtual machine performance. However, I am concerned that additional heat and fan noise might be an issue. I will be running mostly on A/C power so decreased battery life is not a major concern for me. Since I would be running with a Core i7 processor which gives off a fair amount of heat already I was wondering if it might be best to stay at 54000 rpm for the hard drive. What do you all think? Thanks!

• monitoring TCP/IP performance on Solaris

  - by Andy Faibishenko

  I am trying to tune a high message traffic system running on Solaris. The architecture is a large number (600) of clients which connect via TCP to a big Solaris server and then send/receive relatively small messages (.5 to 1K payload) at high rates. The goal is to minimize the latency of each message processed. I suspect that the TCP stack of the server is getting overwhelmed by all the traffic. What are some commands/metrics that I can use to confirm this, and in case this is true, what is the best way to alleviate this bottleneck?
