  • How to view Session Variables in Visual Studio 2008 Debugger?

    - by davemackey
    Usually using Visual Studio's debugger is a breeze. Scanning through Locals quickly shows the values of variables, etc. However, I'm at a loss how to find out the values contained in session state variables? Can anyone give me a hand? Lets say I put a breakpoint right after: Session("first_name") = "Rob Roy" How do I view the value contained in Session("first_name") from locals?

  • Acceptable sound quality: stereo needed for an Android game?

    - by Thomas Calc
    I have various simple short sound effects (damage sound, dying sound, thunderbolt, fanfare, breaking) for a game that is developed for Android currently. I use OGG files: 96kbps VBR, 44.1KHz, 2 channels (that means stereo, right?). I read the other stackexchange topics about "acceptable sound quality", but they're too general, address too many things. My experience is that even with 80kbps, my effects sound OK. But I tested it on a limited number of Android devices (including a Sony Ericsson Xperia Neo and a HTC Desire HD). My questions: For mobile phones and tablets, generally, what parameters are recommended? Won't my 80kbps sounds be bad on a newer device (such as a modern tablet)? I don't hear any difference between stereo and mono (2 channels vs. 1 channel, right?), is there any noticeable difference at all for mobile phones / tablets? (in terms of the player experience) May it worth it at all? I assume that stereo sounds take much more in memory (when they're decoded to PCM), despite of the fact that the compressed OGG size is practically the same. Reacting to Roy T.'s great comment: Actually, I couldn't measure the PCM size (Android decodes OGG internally), but I thought that stereo will take more space than mono when uncompressed After throwing out one of the WAV channels in Audacity, and re-exporting it: The new WAV file size is half than before The OGG file size is practically the same as before The sound effects and game music was recorded by my friend who is an experienced hobby musician/composer, but he knows little about computers & software so he just gave me some high-quality WAV files generated via his hardware.These were stereo, but if I check them in Audacity, both channels appear to be exactly the same.Can I consider them the same (= moving to mono), or might there be some unnoticeable differences to the human eye?

  • My Big Break - this is my story and I am sticking to it ;)

    - by dbasnett
    The value of undertaking new and difficult tasks can have many wonderful consequences, don't you agree? Here is the story of my big break. Remember yours? During the mid 70's I was in the Navy and worked as a computer operator at the CNO's Command and Control computer system (WWMCCS) in the Washington Navy Yard. I was a tape ape, but knew that I wanted to be a systems programmer. One day the Lieutenant in charge of the OS group was running a test that required the development system to be re-booted, and I was politely hinting that I wanted out of computer operations. As he watched the accounting tape rewind to BOT and then search for where it had just been (severalminutes) he told me if I would fix "that" he would have me transferred. I couldn't say "Deal" fast enough. Up until then my programming experience had been on Edsger Dijkstra's favorite computer (sic), an IBM 1620. It took almost 6 months of learning the assembler for the Honeywell 6000 and finding the code responsible for rewinding the tape and then forwarding it. After much trial and error at o’dark thirty I succeeded. The tape barely moved and my “patch” was later adopted by many other sites. Lieutenant Jack Cowan kept his promise and I have gone on to have a varied and enjoyable career. To Jack, and the rest of the crew (Ken, Stu, Neil, Tom, Silent W, Mr. Jacobs, Roy, Rocco, etc.) I’d like to thank you all.

  • Name for Osherove's modified singleton pattern?

    - by Kazark
    I'm pretty well sold on the "singletons are evil" line of thought. Nevertheless, there are limited occurrences when you want to limit the creation of an object. Roy Osherove advises, If you're planning to use a singleton in your design, separate the logic of the singleton class and the logic that makes it a singleton (the part that initializes a static variables, for example) into two separate classes. That way, you can keep the single responsibility principle (SRP) and also have a way to override singleton logic. (The Art of Unit Testing 261-262) This pattern still perpetuates the global state. However, it does result in a testable design, so it seems to me to be a good pattern for mitigating the damage of a singleton. However, Osherove does not give a name to this pattern; but naming a pattern, according to the Gang of Four, is important: Naming a pattern immediately increases our design vocabulary. It lets us design at a higher level of abstraction. (3) Is there a standard name for this pattern? It seems different enough from a standard singleton to deserve a separate name. Decoupled Singleton, perhaps?

  • Should all public methods in an abstract class be marked virtual?

    - by Justin Pihony
    I recently had to update an abstract base class on some OSS that I was using so that it was more testable by making them virtual (I could not use an interface as it combined two). This got me thinking whether I should mark all of the methods that I needed virtual, or if I should mark every public method/property virtual. I generally agree with Roy Osherove that every method should be made virtual, but I came across this article that got me thinking about whether this was necessary or not. I am going to limit this down to abstract classes for simplicity, however (whether all concrete public methods should be virtual is especially debatable, I am sure). I could see where you might want to allow a sub-class to use a method, but not want it overriding the implementation. However, as long as you trust that Liskov's Substitution Principle will be followed, then why would you not allow it to be overriden? By marking it abstract, you are forcing a certain override anyway, so, it seems to me that all public methods inside of an abstract class should indeed be marked virtual. However, I wanted to ask in case there was something I might not be thinking. Should all public methods within an abstract class be made virtual?

  • Globacom and mCentric Deploy BDA and NoSQL Database to analyze network traffic 40x faster

    - by Jean-Pierre Dijcks
    In a fast evolving market, speed is of the essence. mCentric and Globacom leveraged Big Data Appliance, Oracle NoSQL Database to save over 35,000 Call-Processing minutes daily and analyze network traffic 40x faster.  Here are some highlights from the profile: Why Oracle “Oracle Big Data Appliance works well for very large amounts of structured and unstructured data. It is the most agile events-storage system for our collect-it-now and analyze-it-later set of business requirements. Moreover, choosing a prebuilt solution drastically reduced implementation time. We got the big data benefits without needing to assemble and tune a custom-built system, and without the hidden costs required to maintain a large number of servers in our data center. A single support license covers both the hardware and the integrated software, and we have one central point of contact for support,” said Sanjib Roy, CTO, Globacom. Implementation Process It took only five days for Oracle partner mCentric to deploy Oracle Big Data Appliance, perform the software install and configuration, certification, and resiliency testing. The entire process—from site planning to phase-I, go-live—was executed in just over ten weeks, well ahead of the four months allocated to complete the project. Oracle partner mCentric leveraged Oracle Advanced Customer Support Services’ implementation methodology to ensure configurations are tailored for peak performance, all patches are applied, and software and communications are consistently tested using proven methodologies and best practices.

  • Where to place unit test project

    - by Karsten
    I'm thinking about where to put the unit/integration test project. I follow the 1 test project pr. project convention I can think of 3 ways, that all seems good to me, which make it kind of hard to choose :-) Test project is put under a Tests sub folder to the project it tests. Test project is put next to the project it tests, in a "project".Tests folder. I believe this is what Roy Osherove recommends. Put all test projects in a sub folder in the root. e.g. \Tests\"project".Tests Something else? What you choose and why?

  • Practical guide to programming paradigms ?

    - by Pierre
    I think I might be misunderstanding the whole thing and I am looking for some programming wisdom. When faced with a programming challenge, I feel the most important question is "which programming paradigm(s) are better suited to handle it, and how to apply them". A distant second is "which language to use". Yet it seems that most of the programming related content I stumble upon on the Internet has it exactly backwards and focuses mostly on the language choice. An object-oriented solution is fundamentaly the same, whether it's implemented in c++, Java or PHP... So where is the paradigm centered content? Where is the "practical guide to programming paradigms and implementations" and other literature helping bringing real-world and programming concepts together? Note: I already know about "Programming Paradigms for Dummies: What Every Programmer Should Know" from Peter Van Roy.

  • How doe we name test methods where we are checking for more than one condition?

    - by Sandbox
    I follow the technique specified in Roy Osherove's The Art Of Unit Testing book while naming test methods - MethodName_Scenario_Expectation. It suits perfectly well for my 'unit' tests. But,for tests that I write in 'controller' or 'coordinator' class, there isn't necessarily a method which I want to test. For these tests, I generate multiple conditions which make up one scenario and then I verify the expectation. For example, I may set some properties on different instances, generate an event and then verify that my expectations from controller/coordinator is being met. Now, my controller handles events using a private event handler. Here my scenario is that, I set some properties, say 3 condition1,condition2 and condition3 Also, my scenario includes an event is raised I don't have a method name as my event handler is private. How do I name such a test method?

  • Multiple Asserts in a Unit Test

    - by whatispunk
    I've just finished reading Roy Osherove's "The Art of Unit Testing" and I am trying to adhere to the best practices he lays out in the book. One of those best practices is to not use multiple asserts in a test method. The reason for this rule is fairly clear to me, but it makes me wonder... If I have a method like: public Foo MakeFoo(int x, int y, int z) { Foo f = new Foo(); f.X = x; f.Y = y; f.Z = z; return f; } Must I really write individual unit tests to assert each separate property of Foo is initialized with the supplied value? Is it really all that uncommon to use multiple asserts in a test method? FYI: I am using MSTest.

  • Deferred Shading - Toolkit

    - by AliveDevil
    I recently managed to get some lights rendered in a scene by using a buffer and a for-loop. The problem with this method is the performance drop if more lights are used. I tried to convert Deferred Rendering in XNA4.0 | ROY-T.NL but it is not working, because I am not using any models. I know I have to render color, normals and lights seperate but I don't know how I could get it working. For understanding my structure better I'm using a world-class which holds some chunks. These chunks are loading all vertices from their items. These items have a property which returns the vertices. The item is returning VertexPositionNormalTexture[]. The chunk loads these Vertices and combines them to one large array of VertexPositionNormalTexture via someList.AsParallel().SelectMany(m => m).ToArray()). m is a VertexPositionNormalTexture. someList is List<VertexPositionNormalTexture>. I got my own shader to draw these vertices how I want them to be drawn. The first thing I would try is setting up two RenderTarget2D for rendering the color and normal part. With two different shaders. Than I would have to render the lights and there's the problem: I don't know how. I set up a structure to simplify working with lights but it didn't really help. public struct Light { public Vector3 Position; public Color4 Color; public float Range; public float Intensity; public Light( Vector3 position, Color color, float range, float intensity ) : this() { this.Position = position; this.Color = color; this.Range = range; this.Intensity = intensity; } public float[] Definition { get { return new[] { Position.X, Position.Y, Position.Z, Color.Red, Color.Green, Color.Blue, Intensity, Range }; } } } The next part is equally different because I don't know how to combine the colorMap, normalMap and textureMap to one finalMap. Some information to the system: I'm using SharpDX (Nightly from some months ago) and the SharpDX.Toolkit (I don't want to mess up with Direct3DDevice and similar things). Can someone help me with this problem? If things are missing or I provided insufficient information tell me, I need to get deferred shading working. Things I'm not able to do: create a rendertarget which holds all lights, merge colorMap, normalMap and lightMap to one finalMap and presenting this to the user.

  • Performance and Optimization Isn’t Evil

    - by Reed
    Donald Knuth is a fairly amazing guy.  I consider him one of the most influential contributors to computer science of all time.  Unfortunately, most of the time I hear his name, I cringe.  This is because it’s typically somebody quoting a small portion of one of his famous statements on optimization: “premature optimization is the root of all evil.” I mention that this is only a portion of the entire quote, and, as such, I feel that Knuth is being quoted out of context.  Optimization is important.  It is a critical part of every software development effort, and should never be ignored.  A developer who ignores optimization is not a professional.  Every developer should understand optimization – know what to optimize, when to optimize it, and how to think about code in a way that is intelligent and productive from day one. I want to start by discussing my own, personal motivation here.  I recently wrote about a performance issue I ran across, and was slammed by multiple comments and emails that effectively boiled down to: “You’re an idiot.  Premature optimization is the root of all evil.  This doesn’t matter.”  It didn’t matter that I discovered this while measuring in a profiler, and that it was a portion of my code base that can take “many hours to complete.”  Even so, multiple people instantly jump to “it’s premature – it doesn’t matter.” This is a common thread I see.  For example, StackOverflow has many pages of posts with answers that boil down to (mis)quoting Knuth.  In fact, just about any question relating to a performance related issue gets this quote thrown at it immediately – whether it deserves it or not.  That being said, I did receive some positive comments and emails as well.  Many people want to understand how to optimize their code, approaches to take, tools and techniques they can use, and any other advice they can discover. First, lets get back to Knuth – I mentioned before that Knuth is being quoted out of context.  Lets start by looking at the entire quote from his 1974 paper Structured Programming with go to Statements: “We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%. A good programmer will not be lulled into complacency by such reasoning, he will be wise to look carefully at the critical code; but only after that code has been identified.” Ironically, if you read Knuth’s original paper, this statement was made in the middle of a discussion of how Knuth himself had changed how he approaches optimization.  It was never a statement saying “don’t optimize”, but rather, “optimizing intelligently provides huge advantages.”  His approach had three benefits: “a) it doesn’t take long” … “b) the payoff is real”, c) you can “be less efficient in the other parts of my programs, which therefore are more readable and more easily written and debugged.” Looking at Knuth’s premise here, and reading that section of his paper, really leads to a few observations: Optimization is important  “he will be wise to look carefully at the critical code” Normally, 3% of your code – three lines out of every 100 you write, are “critical code” and will require some optimization: “we should not pass up our opportunities in that critical 3%” Optimization, if done well, should not be time consuming: “it doesn’t take long” Optimization, if done correctly, provides real benefits: “the payoff is real” None of this is new information.  People who care about optimization have been discussing this for years – for example, Rico Mariani’s Designing For Performance (a fantastic article) discusses many of the same issues very intelligently. That being said, many developers seem unable or unwilling to consider optimization.  Many others don’t seem to know where to start.  As such, I’m going to spend some time writing about optimization – what is it, how should we think about it, and what can we do to improve our own code.

  • Select * from 'many to many' SQL relationship

    - by Rampant Creative Group
    I'm still learning SQL and my brain is having a hard time with this one. Say I have 3 tables: teams players and teams_players as my link table All I want to do is run a query to get each team and the players on them. I tried this: SELECT * FROM teams INNER JOIN teams_players ON teams.id = teams_players.team_id INNER JOIN players ON teams_players.player_id = players.id But it returned a separate row for each player on each team. Is JOIN the right way to do it or should I be doing something else? ----------------------------------------- Edit Ok, so from what I'm hearing, this isn't necessarily a bad way to do it. I'll just have to group the data by team while I'm doing my loop. I have not yet tried the modified SQL statements provided, but I will today and get back to you. To answer the question about structure - I guess I wasn't thinking about the returned row structure which is part of what lead to my confusion. In this particular case, each team is limited to 4 players (or less) so I guess the structure that would be helpful to me is something like the following: teams.id, teams.name, players.id, players.name, players.id, players.name, players.id, players.name, players.id, players.name, 1 Team ABC 1 Jim 2 Bob 3 Ned 4 Roy 2 Team XYZ 2 Bob 3 Ned 5 Ralph 6 Tom

  • Customizing orchard theme parts

    - by madcapnmckay
    Hi, I am trying to write a custom theme for orchard and am not having much success so far. I have read Bertrand Le Roy's article on part alternates but I can't seem to get it to work. I am displaying a list of recent blog posts on the front page, pretty standard. I wish to change the markup produced by the meta data part i.e the time format. I have written a IShapeTableProvider to create blog specific alternates for the metadata summary part. public class MetaDataShapeProvider : IShapeTableProvider { private readonly IWorkContextAccessor workContextAccessor; public MetaDataShapeProvider(IWorkContextAccessor workContextAccessor) { this.workContextAccessor = workContextAccessor; } public void Discover(ShapeTableBuilder builder) { builder .Describe("Parts_Common_Metadata_Summary") .OnDisplaying(displaying => { ContentItem contentItem = displaying.Shape.ContentItem; if (contentItem != null) displaying.ShapeMetadata.Alternates.Add("Metadata__" + contentItem.ContentType); }); } } This is being caught correctly but the contentItem is null. Should I just create an alternate with a fixed name like "Metadata-BlogPost" and use that, to make this general purpose it should really be a dynamic name so I can use another alternate template elsewhere. Thanks, Ian
