• Training v. Teaching

  - by Chris Gardner

  Originally posted on: http://geekswithblogs.net/freestylecoding/archive/2014/05/28/training-v.-teaching.aspxAs some of you may know, I recently accepted a position to teach an undergraduate course at my alma mater. Yesterday, I had my first day in an academic classroom. I immediately noticed a difference with the interactions between the students. They don't act like students in a professional training or conference talk. I wanted to use this opportunity to enumerate some of those differences. The immediate thing I noticed was the lack of open environment. This is not to say the class was hostile towards me. I am used to entering the room, bantering with audience, loosening everyone a bit, and flowing into the discussion. A purely academic audience does not banter. At least, they do not banter on day one. I think I can attribute this to two factors. This first is a greater perception of authority. In a training or conference environment, I am an equal with the audience. This is true even if I am being a subject matter expert. We're all professionals. We're all there to learn from each other, share our stories, and enjoy the journey. In the academic classroom, there was a distinct class difference. I had forgotten about this distinction; I had the professional familiarity with the staff by the time I completed my masters. This leads to the other distinction. These was an expectation of performance. At conference and professional training, there is generally no (immediate) grading. This may be a preparation for a certification exam, but I'm not the one responsible for delivering the exam. This was not the case in the academic classroom. These students are battling for points, and I am the sole arbiter. These students are less likely to let the material wash over them, applying the material to their past experiences. They were down taking notes. I don't want to leave the impression that there was no interact in the classroom. I spent a good deal of time doing problems with the class on the whiteboard. I tried to get the class to help me work out the steps. This opened up a few of them. After every conference or training class, I always get a few people that will email me afterward to continue the conversation. I am very curious to see if anybody comes to my office hours tomorrow. However, that is a curiosity that will have to wait until tomorrow.

• No suspend on lid closing on a Samsung Series 5 14" NP530U4BI

  - by dmeu

  Ok, i realize I am not the only one, but I will try to provide all info possible to make it exemplary as possible and narrow down the error sources. I have a fresh install of Ubuntu 12.04 and the suspend worked fine upon having it freshly installed but now it does not anymore. The suspend option from the system power button on the top right works fine. Things I did do which I don't know if they are related: Install and remove againthe FGLRX drivers (Radeon graphic card) Install Jupiter power managment (shutting it down is not changin anything) Plug in and out an external display The configuration I know of is well set: In System Settings/Power all is set to suspend when closing lid Double checked with dconf-editor, everything set to suspend So, from here on I don't know how to proceed.. what are common problems that cause this error?

• SFX Played Once per Collision or Hit

  - by David Dimalanta

  I have a question about using Box2D (engine for LibGDX used to make realistic physics). I observed on the code that I've made for the physics here below: @Override public boolean touchUp(int screenX, int screenY, int pointer, int button) { // TODO Touch Up Event if(is_Next_Fruit_Touched) { BodyEditorLoader Fruit_Loader = new BodyEditorLoader(Gdx.files.internal("Shape_Physics/Fruity Physics.json")); Fruit_BD.type = BodyType.DynamicBody; Fruit_BD.position.set(x, y); FixtureDef Fruit_FD = new FixtureDef(); // --> Allows you to make the object's physics. Fruit_FD.density = 1.0f; Fruit_FD.friction = 0.7f; Fruit_FD.restitution = 0.2f; MassData mass = new MassData(); mass.mass = 5f; Fruit_Body[n] = world.createBody(Fruit_BD); Fruit_Body[n].setActive(true); // --> Let your dragon fall. Fruit_Body[n].setMassData(mass); Fruit_Body[n].setGravityScale(1.0f); System.out.println("Eggs... " + n); Fruit_Loader.attachFixture(Fruit_Body[n], Body, Fruit_FD, Fruit_IMG.getWidth()); Fruit_Origin = Fruit_Loader.getOrigin(Body, Fruit_IMG.getWidth()).cpy(); is_Next_Fruit_Touched = false; up = y; Gdx.app.log("Initial Y-coordinate", "Y at " + up); //Once it's touched, the next fruit will set to drag. if(n < 50) { n++; }else{ System.exit(0); } } return true; } Now, I'm thinking which part o line should I implement for the sound effects. My objectives to make SFX played once for every collision (Or should I say "SFX played once per collision"?) on the following: SFX played once if they hit on the objects of its kind. (e.g. apple vs. apple) SFX played once on a different sound when it hit on the ground. (e.g. apple land on the mud) Take note that I'm using Box2D for the Java programming version thanks to LibGDX via Box2D engine and I edited the physics body using Physics Body Editor before I implement it to code. I tried to check every available methods for body, fixture definition, or body definition to code for the SFX when hit but it seems only for the gravity and weight. Is there possibly available on the document for SFX played when collision happens if possible?

• On the art of self-promotion

  - by Tony Davis

  I attended Brent Ozar's Building the Fastest SQL Servers session at Tech Ed last week, and found myself engulfed in a 'perfect storm' of excellent technical and presentational skills coupled with an astute awareness of the value of promoting one's work. I spend a lot of time at such events talking to developers and DBAs about the value of blogging and writing articles, and my impression is that some could benefit from a touch less modesty and a little more self-promotion. I sense a reticence in many would-be writers. Is what I have to say important enough? Haven't far more qualified and established commentators, MVPs and so on, already said it? While it's a good idea to pick reasonably fresh and interesting topics, it's more important not to let such fears lead to writer's block. In the eyes of any future employer, your published writing is an extension of your resume. They will not care that a certain MVP knows how to solve problem x, but they will be very interested to see that you have tackled that same problem, and solved it in your own way, and described the process in your own voice. In your current job, your writing is one of the ways you can express to your peers, and to the organization as a whole, the value of what you contribute. Many Developers and DBAs seem to rely on the idea that their work will speak for itself, and that their skill shines out from it. Unfortunately, this isn't always true. Many Development DBAs, for example, will be painfully aware of the massive effort involved in tuning and adding resilience to rapidly developed applications. However, others in the organization who are unaware of what's involved in getting an application that is 'done' ready for production may dismiss such efforts as fussiness or conservatism. At the dark end of the development cycle, chickens come home to roost, but their droppings tend to land on those trying to clear up the mess. My advice is this: next time you fix a bug or improve the resilience or performance of a database or application, make sure that you use team meetings, informal discussions and so on to ensure that people understand what the problem was and what you had to do to fix it. Use your blog to describe, generally, the process you adopted, the resources you used and the insights that came from your work. Encourage your colleagues to do the same. By spreading the art of self-promotion to everyone involved in an IT project, we get a better idea of the extent of the work and the value of the contribution of all the team members. As always, we'd love to hear what you think. This very week, Simple-talk launches its new blogging platform. If any of this has moved you to 'throw your hat into the ring', drop us a mail at [email protected]. Cheers, Tony.

• BIDS Helper 1.6 Beta Release (now with SQL 2012 support!)

  - by Darren Gosbell

  The beta for BIDS Helper 1.6 was just released. We have not updated the version notification just yet as we would like to get some feedback on people's experiences with the SQL 2012 version. So if you are using SQL 2012, go grab it and let us know how you go (you can post a comment on this blog post or on the BIDS Helper site itself). This is the first release that supports SQL 2012 and consequently also the first release that runs in Visual Studio 2010. A big thanks to Greg Galloway for doing the bulk of the work on this release. Please note that if you are doing an xcopy deploy that you will need to unblock the files you download or you will get a cryptic error message. This appears to be caused by a security update to either Visual Studio or the .Net framework – the xcopy deploy instructions have been updated to show you how to do this. Below are the notes from the release page. ====== This beta release is the first to support SQL Server 2012 (in addition to SQL Server 2005, 2008, and 2008 R2). Since it is marked as a beta release, we are looking for bug reports in the next few months as you use BIDS Helper on real projects. In addition to getting all existing BIDS Helper functionality working appropriately in SQL Server 2012 (SSDT), the following features are new... Analysis Services Tabular Smart Diff Tabular Actions Editor Tabular HideMemberIf Tabular Pre-Build Fixes and Updates The Unused Datasets feature for Reporting Services now accounts for new features in Reporting Services 2008 R2 like Lookups and new features in Reporting Services 2012. SSIS: emit an informational message when a variable has an expression defined and EvaluateAsExpression = False SSAS: roles reports points to wrong server SSIS - Variable Copy / Move broken in v1.5 "Unused DataSets Report" not showing up in Context menu on VS2005 if Solution Folders used SSAS Tabular: Create a UI for managing actions SSAS Tabular: Smart Diff improvements for new schema and Tabular models SSIS: Copy/Move Variable Erroring due to custom Control Flow item Icon SSIS Performance Visualization Index out of range fixing bugs in AggManager when aggregation design IDs don't match names The exe downloads are a self extracting installer, the zip downloads allow for an xcopy deploy. Make sure to note the updated xcopy deploy instructions for SQL Server 2012.

• TransportWithMessageCredential & Service Bus – Introduction

  - by Michael Stephenson

  Recently we have been working on a project using the Windows Azure Service Bus to expose line of business applications. One of the topics we discussed a lot was around the security aspects of the solution. Most of the samples you see for Windows Azure Service Bus often use the shared secret with the Access Control Service to protect the service bus endpoint but one of the problems we found was that with this scenario any claims resulting from credentials supplied by the client are not passed through to the service listening to the service bus endpoint. As an example of this we originally were hoping that we could give two different clients their own shared secret key and the issuer for each would indicate which client it was. If the claims had flown to the listening service then we could check that the message sent by client one was a type they are allowed to send. Unfortunately this claim isn't flown to the listening service so we were unable to implement this scenario. We had also seen samples that talk about changing the relayClientAuthenticationType attribute would allow you to authenticate the client within the service itself rather than with ACS. While this was interesting it wasn't exactly what we wanted. By removing the step where access to the Relay endpoint is protected by authentication against ACS it means that anyone could send messages via the service bus to the on-premise listening service which would then authenticate clients. In our scenario we certainly didn't want to allow clients to skip the ACS authentication step because this could open up two attack opportunities for an attacker. The first of these would allow an attacker to send messages through to our on-premise servers and potentially cause a denial of service situation. The second case would be with the same kind of attack by running lots of messages through service bus which were then rejected the attacker would be causing us to incur charges per message on our Windows Azure account. The correct way to implement our desired scenario is to combine one of the common options for authenticating against ACS so the service bus endpoint cannot be accessed by an unauthenticated caller with the normal WCF security features using the TransportWithMessageCredential security option. Looking around I could not find any guidance on how to implement this correctly so on the back of setting this up I decided to write a couple of articles to walk through a couple of the common scenarios you may be interested in. These are available on the following links: Walkthrough - Combining shared secret and username token Walkthrough – Combining shared secret and certificates

• What actions does Ubuntu trigger when battery is low?

  - by blueyed

  When the battery is low, the screen gets dimmed after a few seconds already. This appears to be some special power-saving mode, and might be related to the time in org.gnome.settings-daemon.plugins.power.time-low (1200 seconds (20 minutes) the default). While this seems to get triggered by gnome-settings-daemon, I wonder what else Ubuntu does when this happens (e.g. via DBus listeners), or other event listeners that look for a "low battery" state. It seems like something in this regard causes Ubuntu / X / the system to behave more sluggish afterwards (when the laptop is on AC again), and I would like to look into what might be causing this. I could not find anything related via dconf-editor, e.g. in org.gnome.settings-daemon.plugins.power. It appears to get setup via idle_configure in plugins/power/gsd-power-manager.c, but it's probably something more related to something that listens on the DBus interface, which gets notified via e.g.: if (!g_dbus_connection_emit_signal (manager->priv->connection, NULL, GSD_POWER_DBUS_PATH, "org.freedesktop.DBus.Properties", "PropertiesChanged", props_changed, &error)) I could imagine that some "power saving" property gets set, but not unset when AC is available anymore and/or the battery is not low anymore. I have looked at the CPU governor setting (/sys/devices/system/cpu/cpu*/cpufreq/scaling_governor), but it was ondemand. I am using gnome-settings-daemon with awesomeWM on Ubuntu 14.04. gnome-settings-daemon=3.8.6.1-0ubuntu11.1 I've also compared gsd's plugins/power/gsd-power-manager.c with the one from Debian's gnome-settings-daemon-3.12.1, but could not find anything obvious that might have been fixed/changed in this regard. I have managed to trigger the gnome-power-manager's gnome-settings plugin (which dims the screen etc), by patching upower and use it after killing the system's upower daemon. (note that it's probably only energy that is being used by gpm to calculate it by itself). It does not make the system become sluggish.. OTOH I have not heard the speaker's beeping, which might come from the BIOS, which might be involved here, too - or other programs using the kernel's interface on /sys/class/power_supply/BAT0/. --- src/linux/up-device-supply.c.orig 2014-06-07 16:48:32.735920661 +0200 +++ src/linux/up-device-supply.c 2014-06-07 16:48:39.391920525 +0200 @@ -821,6 +821,9 @@ supply->priv->energy_old_first = 0; } + percentage = 3.1f; + time_to_empty = 3*60; + energy = 5; g_object_set (device, "energy", energy, "energy-full", energy_full,

• BizTalk: Using context for routing

  - by Leonid Ganeline

  [See Sample: Context routing and throttling with orchestration] Imagine the project where most of the routing happens between orchestrations. I.e. routing is mostly between the MessageBox and orchestration with direct endpoints. Imagine also the most of the messages are with the same Message type. Usually in this case messages got the special node only for the routing. For example, the field can be the “Originator” or “Recipient” or “From” or “To”. What wrong is with this approach, it creates the dependency between the message and the message processing. Message “knows” something about Originator or Recipient. So what we can do with it? How can we “colorize” the same message to route it to the different places without changing the message itself? One of the decisions is to use the message context. BizTalk uses the promoted properties for routing.  There are two kinds of the properties: the content properties and the context properties. The content property extracts its value from inside the message, it is a value of the element or attribute. [See MSDN] The context property gets its value from the message environment. It can be the port name that receive this message, it can be the message Id, created by the BizTalk. Context properties look like the headers in the SOAP message. Actually they are not the headers but behave like headers. The context properties are the good match for our case. First, we don’t have to change the message itself to set or change the routing property. The context is stored outside the message body. Second, we don’t have to create the property schema to use the context properties. [See MSDN: How to create Property schema] BizTalk has the predefined schema set for the context properties. [See MSDN: Message Context Properties] Use one of them and that's it. The main purpose of the context properties is working on behalf of the BizTalk internals. But we can read, create and change them. Just do not interfere with BizTalk internals on this way.

• Professional immigration

  - by etranger

  Hello all, Does anyone here have a practical advice on professional relocation from Russia to Europe? The reasons behind making such a decision are far beyond the subject, perhaps, so I'll stick to the practical part. Having done some of the "common stuff" for finding a job, I am now facing two serious problems: I am a "dual-class" person, with university degree in marketing, and multiple years of self-studied computer competence (hence my writing here). Have professional experience in both areas. I don't currently hold a European work permit. From what I can see, this results in normal HR person throwing out my CV as either being "overqualified" or "too much trouble with making the permit". I do have the skills and character to start my own business, but it requires start-up capital that I don't have, over the last years I had to pay high bills for medical treatment of my family member, who had deceased. Now, I'm almost out of debts. As you can probably guess, English is not a problem, and I'm open to new languages, but first steps of entering the market, or the society, is the problematic part. I live close to Norway, and am trying to get some professional contacts there, but it hasn't got me any practical perspective so far. Any advice is greatly appreciated. EDIT: I am currently making my living off web site development, and occasional consulting services both in IT and marketing. For purely geographic reasons I'm dealing with clients that reside in the same city where I live, pop. 350 000. Being quite local, market requirements for web sites are simple and stable — clients need to control navigation, write articles in a word-like editor, upload illustrations and place ad banners, all with no additional programming. As many web developers do, I'm using my own content management system that fits these expectations. I have also started developing a newer version of this system that has better support for international environments, but I'm too distant from the real market demand in Europe to speak of the right track here. Technically it's based on php/mysql and uses xslt for templating. It allows for quick website deployment, and has architectural neatness, lack of which made me abandon similar opensource solutions (Joomla and the like). Deploying time from rasterized design proofs is normally under 6-8 working hours, don't know how that compares to the world practice. EDIT 2: Can anyone share what Norwegian (Scandinavian) web solutions market currently demands?

• Where does a "Technical Programmer" fit in, and what does the title mean? [closed]

  - by Mike E

  Was: "What is a 'Technical Programmer'"? I've noticed in job posting boards a few postings, all from European companies in the games industry, for a "Technical Programmer". The job description was similar, having to do with tools development, 3d graphics programming, etc. It seems to be somewhere between a Technical Artist who's more technical than artist or who can code, and a Technical Director but perhaps without the seniority/experience. Information elsewhere on the position is sparse. The title seems redundant and I haven't seen any American companies post jobs by that name, exactly. One example is this job posting on gamedev.net which isn't exactly thorough. In case the link dies: Subject: Technical Programmer Frictional Games, the creators of Amnesia: The Dark Descent and the Penumbra series, are looking for a talented programmer to join the company! You will be working for a small team with a big focus on finding new and innovating solutions. We want you who are not afraid to explore uncharted territory and constantly learn new things. Self-discipline and independence are also important traits as all work will be done from home. Some the things you will work with include: 3D math, rendering, shaders and everything else related. Console development (most likely Xbox 360). Hardware implementations (support for motion controls, etc). All coding is in C++, so great skills in that is imperative. Revised Summarised Question: So, where does a programmer of this nature fit in to software development team? If I had these on my team, what tasks am I expecting them to complete? Can I ask one to build a new level editor, or optimize the rendering engine? It doesn't seem to be a "tools programmer" which focuses on producing artist tools, often in high-level languages like C#, Python, or Java. Nor does it seem to be working directly on the engine, nor a graphics programmer, as such. Yet, a strong C++ requirement, which was mirrored in other postings besides this one I quoted. Edited To Add As far as it being a low-level programmer, I had considered that but lacking from the posting was a requirement of Assembly. Instead, they tend to require familiarity with higher-level hardware APIs such as DirectX, or DirectInput. I wasn't fully clear in my original post. I think, however, that Mathew Foscarini has it right in his answer, so barring someone who definitely works with or as a "Technical Programmer" stepping in to provide a clearer explanation, I'll go with that. A generalist, which also fits the description of a more-technical-than-artist TA.

• Styling Windows Phone Silverlight Applications

  - by Tim Murphy

  If you have not developed with styles in Silverlight/XAML then it can be challenging and resources can be sparse depending on how deep you get.  One thing that you need to understand is what level you can apply styles and how much they can cascade.  What I am finding is that this doesn’t go to the level that we are used to in HTML and CSS. While styles can be defined at a page level if you want to share styles throughout your application they should be defined in the App.xaml file.  This is of course analogous to placing a style in your HTML file versus an external CSS file.  This is the type of style I will concentrate on in this post. The first thing to look it how styles associate to elements.  TargetType defines the object type that your style will apply to.  In the example below the style is targeting the TextBlock object type. <Style x:Key="TextBlockSmallGray" TargetType="TextBlock"> Next we use a Setter which allows you to apply values for specific attributes of the target object type.  The setters can be a simple value or complex.  The first example here is simply applying a color to the background property of the target. <Setter Property="Background" Value="White"/> The second setter example here is for the same property, but we are applying a the definition of a LinearGradientBrush. <Setter Property="Background"> <Setter.Value> <LinearGradientBrush> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset="1" Color="White"/> </LinearGradientBrush> </Setter.Value> </Setter> The last thing I want to cover here is that you can leverage the system styles and then override or extend them.  The BasedOn attribute of the Style tag allows this sort of inheritance.  In the example below I am going to start with the PhoneTextTitleStyle and then override properties as needed. <Style x:Key="TextBlockTitle" BasedOn="{StaticResource PhoneTextTitle1Style}" TargetType="TextBlock"> So now that we have our styles defined applying it is fairly straight forward.  Add the style name as a static resource to the style property of the element in your page and off you go. <Grid x:Name="LayoutRoot" Style="{StaticResource PageGridStyle}"> So this is one step in creating consistency in your application’s look.  In future posts I will dig a little deeper. del.icio.us Tags: windows phone 7,mobile development,windows phone 7 development,.NET,software development,design,UX

• Adding Facebook Open Graph Tags to an MVC Application

  - by amaniar

  If you have any kind of share functionality within your application it’s a good practice to add the basic Facebook open graph tags to the header of all pages. For an MVC application this can be as simple as adding these tags to the Head section of the Layouts file.<head> <title>@ViewBag.Title</title> <meta property="og:title" content="@ViewBag.FacebookTitle" /> <meta property="og:type" content="website"/> <meta property="og:url" content="@ViewBag.FacebookUrl"/> <meta property="og:image" content="@ViewBag.FacebookImage"/> <meta property="og:site_name" content="Site Name"/> <meta property="og:description" content="@ViewBag.FacebookDescription"/></head>  These ViewBag properties can then be populated from any action: private ActionResult MyAction() { ViewBag.FacebookDescription = "My Actions Description"; ViewBag.FacebookUrl = "My Full Url"; ViewBag.FacebookTitle = "My Actions Title"; ViewBag.FacebookImage = "My Actions Social Image"; .... } You might want to populate these ViewBag properties with default values when the actions don’t populate them. This can be done in 2 places. 1. In the Layout itself. (check the ViewBag properties and set them if they are empty) @{ ViewBag.FacebookTitle = ViewBag.FacebookTitle ??

• New Features Of WordPress 3.3 You Must Know

  - by Gopinath

  After months of beta testing, WordPress 3.3 version is going to be released at the end of this month. There are several new features packed in the new version and few of them are going to excite WordPress admins. In this post we are going to discuss about the exciting new features. 1. Drag and Drop Media Uploads One of the biggest improvements in this version of WordPress is it’s all new media uploader. Now you can upload multiple files by just dragging & dropping, instantly resize  the images and filter files by their type. The media upload sports a brand new look WordPress adopted the Pupload plugin to power its media uploader component and it’s written by the same team who created the popular TinyMCE editor plugin. 2. Improved Admin Bar(Toolbar) The admin bar or newly called toolbar has got handful of makeovers. The not so much used items like Search box and other elements are removed to make sure that the bar is not clumsy. The user menu and the related options are moved to the right like how we see in Google’s user bar. Also there are few changes to the colour of the bar to make it more eye friendly. 3. Fly out Admin Menus All the left side bar menus of WordPress admin are now sports a fly out menu style to save a click. In the previous versions if you want to access a sub menu on the left side bar, you need to first click on the category and then choose the menu item from the expanded list. Now on just mouse over you will see a flyout of menu items. 4. Adaptive Admin – Layout Auto Adjust To Fit Various Devices If you own an iPad or any other so called tablets then you are going to love this feature. The admin site of WordPress has got a lot more friendly with tablets and smartphones. WordPress now auto adjusts layout to fit the device through which you are accessing the admin site.  Accessing admin dashboard on your tablets is going to be more fun. 5. Other Features Now that we have read the most useful 4 features here is a small list of other features that may interest you Nice Tooltips are displayed where ever possible to help the newbies to understand the usage of admin site Responsive Layouts jQuery 1.7 and jQuery UI 1.8.16 are the power horses of WordPress Performance improvements This article titled,New Features Of WordPress 3.3 You Must Know, was originally published at Tech Dreams.

• "Untrusted packages could compromise your system's security." appears while trying to install anything

  - by maria

  Hi I've freshly installed Ubuntu 10.4 on a new computer. I'm trying to install on it application I need (my old computer is broken and I have to send it to the service). I've managed to install texlive and than I can't install anything else. All software I want to have is what I have succesfuly installed on my old computer (with the same version of Ubuntu), so I don't understand, why terminal says (sorry, the terminal talks half English, half Polish, but I hope it's enough): maria@marysia-ubuntu:~$ sudo aptitude install emacs Czytanie list pakietów...

To continue, enter "Yes"; to abort, enter "No" I was trying to install other editors as well, with the same result. As I decided that I might be sure that I know the package I want to install is secure, finaly I've entered "Yes". The installation ended succesfuly, but editor don't understand any .tex file (.tex files are for sure fine): this is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009/Debian) restricted \write18 enabled. entering extended mode (./Szarfi.tex !

• Crash when using datablocks

  - by scorcher24

  I have really throughly searched the net and could not find any solution for this so I ask for help here. Anyway, I have this datablock in datablocks.cs: datablock t2dSceneObjectDatablock(EnemyShipConfig) { canSaveDynamicFields = "1"; Layer = "3"; size = "64 64"; CollisionActiveSend = "1"; CollisionActiveReceive = "1"; CollisionCallback = true; CollisionLayers = "3"; CollisionDetectionMode = "POLYGON"; CollisionPolyList = "0.00 -0.791 0.756 0.751 -0.746 0.732"; UsesPhysics = "0"; Rotation = "-90"; WorldLimitMode = "KILL"; WorldLimitMax = "880 360"; WorldLimitMin = "-765 -436"; minFireRate = "2000"; maxFireRate = "1200"; laserSpeed = "800"; minSpeed = "100"; maxSpeed = "150"; }; This is an exact reproduction of an object that I have manually edited in the editor. So far, I just used clone() to get as many enemies as I need, while it was out of sight. It is a r-type style shooter, so I need a variable amount of enemies. Since clone() spams my log, I decided to use datablocks, since it is also more flexible. That's what I get when I use clone(): Con::execute - 0 has no namespace: onRemoveFromScene However, once spawning begins, my game freezes and crashes: function SpawnEnemy() { //%spawnedEnemy = EnemyShipMaster.clone(true); %spawnedEnemy = new t2dStaticSprite() { class = "EnemyShip"; sceneGraph = $global_sceneGraph; datablock = "EnemyShipConfig"; imageMap = "starshipImageMap"; layer = 3; }; %speed = getRandom(%spawnedEnemy.minSpeed, %spawnedEnemy.maxSpeed); %y = getRandom(-320, 320); // Set Properties %spawnedEnemy.setPositionX(700); %spawnedEnemy.setPositionY(%y); %spawnedEnemy.setVisible(true); %spawnedEnemy.setLinearVelocityX( -%speed ); %spawnedEnemy.setTimerOn( getRandom( %spawnedEnemy.maxFireRate, %spawnedEnemy.minFireRate ) ); } // Definition of $global_sceneGraph from game.cs: $global_sceneGraph = sceneWindow2D.loadLevel(%level); As I said, it works fine when I use clone() (which is commented out here), but my log gets spammed. I really hope someone can shed some light for me, this is driving me crazy.

• Deploying, but without those pesky test files!

  - by Chris Skardon

  Silverlight testing is great, we all know that (don’t we??), we’re expected to do it as part of the development process, but once we’ve got an awesome application written and we come to deploy it, we don’t want the test files going out with it… You might be like me, have the files in a Web project – let’s face it, that’s how we’re pushed into doing it… So let’s stick with it! Now. I’m deploying via the wonders of the Web Deployment shizzle, but this also applies to the classic ‘installer’ project as well.. Baaaasically, we’re going to use the ‘Debug’ / ‘Release’ configurations to include given files. ?? OK, you know in the top of your visual studio editor, you (usually) have a drop down which predominantly reads ‘Debug’? Those are ‘configurations’. Mostly we don’t bother changing it, primarily due to laziness, but also the fact that we generally don’t see ‘Release’ as actually doing anything other than making it harder to find problems :) Well today my friends we’re going to change that bad boy… The next few steps are just helping you set up a new ‘Debug’ configuration, but you can just switch to the ‘Release’ configuration and skip to the end… First let’s go to the Configuration Manager. There are multiple ways, through the ‘Build’ menu (at the bottom), or via the drop down which currently has ‘Debug’ in it :) Got it? Select ‘New’ from the ‘Active solution configuration’ drop down: Create a new configuration, kind of like the picture below shows (or for those graphically challenged – Name: DebugWithNoTests, and Copy settings from: ‘Debug’, ensuring the ‘Create new project configurations’ checkbox is checked). Press OK. VS will do some shizzle, and in the Configuration manager, you will see pretty much exactly what you did before, only with ‘Debug’ replaced with ‘DebugWithNoTests’. Turn off the build options for the test projects. We won’t need them.. IF you skipped down from the top, this is where you’ll be wanting to stop!!! Close and now we’re one notepad step away from achieving our goals. Yes, I said notepad. You can’t do what we’re going to do in VS. (Pity). Go to the folder where your web project is, and right click on the ‘.csproj’ file. Now open it with notepad. Head on down to the ‘<Content Include’ bits, they’ll look like this: <ItemGroup> <Content Include="ClientBin\Tests.xap" /> ... </ItemGroup> Take this and modify each of the files you don’t want deployed and change to: <Content Include="ClientBin\Tests.xap" Condition="'$(Configuration)' == 'Debug'" /> Once you’ve got that sorted publish your project, once with the Debug configuration selected, and another with any other configuration (‘Release’, ‘DebugWithNoTests’ etc).. No files! Huzzah!

• Why are MVC & TDD not employed more in game architecture?

  - by secoif

  I will preface this by saying I haven't looked a huge amount of game source, nor built much in the way of games. But coming from trying to employ 'enterprise' coding practices in web apps, looking at game source code seriously hurts my head: "What is this view logic doing in with business logic? this needs refactoring... so does this, refactor, refactorrr" This worries me as I'm about to start a game project, and I'm not sure whether trying to mvc/tdd the dev process is going to hinder us or help us, as I don't see many game examples that use this or much push for better architectural practices it in the community. The following is an extract from a great article on prototyping games, though to me it seemed exactly the attitude many game devs seem to use when writing production game code: Mistake #4: Building a system, not a game ...if you ever find yourself working on something that isn’t directly moving your forward, stop right there. As programmers, we have a tendency to try to generalize our code, and make it elegant and be able to handle every situation. We find that an itch terribly hard not scratch, but we need to learn how. It took me many years to realize that it’s not about the code, it’s about the game you ship in the end. Don’t write an elegant game component system, skip the editor completely and hardwire the state in code, avoid the data-driven, self-parsing, XML craziness, and just code the damned thing. ... Just get stuff on the screen as quickly as you can. And don’t ever, ever, use the argument “if we take some extra time and do this the right way, we can reuse it in the game”. EVER. is it because games are (mostly) visually oriented so it makes sense that the code will be weighted heavily in the view, thus any benefits from moving stuff out to models/controllers, is fairly minimal, so why bother? I've heard the argument that MVC introduces a performance overhead, but this seems to me to be a premature optimisation, and that there'd more important performance issues to tackle before you worry about MVC overheads (eg render pipeline, AI algorithms, datastructure traversal, etc). Same thing regarding TDD. It's not often I see games employing test cases, but perhaps this is due to the design issues above (mixed view/business) and the fact that it's difficult to test visual components, or components that rely on probablistic results (eg operate within physics simulations). Perhaps I'm just looking at the wrong source code, but why do we not see more of these 'enterprise' practices employed in game design? Are games really so different in their requirements, or is a people/culture issue (ie game devs come from a different background and thus have different coding habits)?

• The difference

  So with the CTP tools available, weve been building a few apps, just to get a feel for the tools and whats supported in the framework.  Whats been great is that everything is fairly familiar and consistent, largely to do with the .net framework and Microsofts focus on providing good tools.  Weve produced mobile applications, mostly in concept form, for Windows Phone Classic, iPhone and Android but never so quickly and not of such high quality and visual impression.  I attribute some of this obviously to our familiarity to the Microsoft platform and tools.  Though when you look at the designs our team has produced, it becomes clear that this is not just another mobile application container.                                                            The Metro design language implores content prominence with fluid motion and transitions, with a crisp font and easily organized features and services placement.  In addition to a purposeful right edge tease, where the intent is for users to discover new premium content and services.   The concept that enables this is called hubs, building application with hubs changes your thinking from a single mobile application task, to thinking creatively about a mobile experience. Its engaging to think of the other brands and industry verticals that will take advantage of this core feature.  Combine this with Windows Phone 7 live tiles, more on that later, and you have a recipe for a solid mobile services platform.                                                              This so much more fun and liberating than my icon on a gridDid 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.

• Visual Studio 2010/2012 Context Menus and a Keyboard

  - by SergeyPopov

  As a software developer, I spend a lot of time using Visual Studio. I have to say that I completely satisfied with Visual Studio generally. Nevertheless, sometimes Visual Studio starts annoying me. One issue which poisoned my existence for a long time is that context menu behavior in VS2010 is a little different than it was in VS2005/2008. Unfortunately, in VS2012 this behavior remains the same as in VS2010. So, what is the issue? Working with Visual Studio, I use the keyboard in most cases. I also use the Apps key on the keyboard to open context menus in the code editor. Moreover, long time ago I am got used to using some key sequences, and press the keys without even thinking. In VS2008, a mouse pointer position didn’t affect context menu navigation if I used the keyboard. Every time I opened a context menu I was sure that, for example, the "Apps, Down, Down, Enter, Up, Enter" key sequence always invoke "Organize Usings > Remove and Sort" function. But in VS2010, this behavior has been changed. If a mouse pointer is located over an opened context menu, the menu item under the mouse pointer becomes selected immediately! So, now the "Apps, Down, Down, Enter, Up, Enter" key sequence will not lead to expected results all the time. In some cases, the result may be a little scary. If you are using Visual SVN extension, this key sequence may invoke "Revert whole file" function. Of course, this is not a fatal problem because "Undo" function restores all the changes, but this behavior strongly annoys me. In Visual Studio 2012, context menu behavior is a little different than in VS2010, but a mouse pointer position still affects the keyboard navigation in the context menu, and this behavior is still annoying. I tried to find the way how to change this behavior, but I didn’t manage to find the answer quickly. Then I decided to go right though, so I wrote a small utility which fixes this issue. This utility watches for Apps key, and if the key is pressed in Visual Studio, the utility moves the mouse pointer to the top of the screen before opening the context menu. You can find binaries and the source code of this utility here: http://code.google.com/p/vs-ctx-menu-fix/downloads/list This utility works fine in Windows 7 and Windows 8 x64. I wrote the first version in January, 2011; now I just added Visual Studio 2012 support. I hope you will find this utility useful! :)

• To Obtain EPOCH Time Value from a Packed BIT Structure in C [migrated]

  - by xde0037

  This is not a home assignment! We have a binary data file which has following data structure: (It is a 12 byte structure): I need to find out Epoch time value(total time value is packed in 42 bits as described below): Field-1 : Byte 1, Byte 2, + 6 Bits from Byte 3 Time-1 : 2 Bits from Byte 3 + Byte 4 Time-2 : Byte 5, Byte 6, Byte 7, Byte 8 Field-2 : Byte 9, Byte 10, Byte 11, Byte 12 For Field-1 and Field-2 I do not have issue as they can be taken out easily. I need time value in Epoch Time (long) as it has been packed in Bytes 5,6,7,8 and 3 and 4 as follows: (the bit structure for the time value is as follows): Bytes 5 to 8 (32 bit word) Packs time value bits from 0 thru 31 (byte 5 has 0 to 7 bits, byte 6 has 8 to 15, byte 7 has 16 to 23, byte 8 has 24 to 31). the remaining 10 bits of time value are packed in Bytes 3 and byte 4 as follows: byte 3 has 2 bits:32 and 33, and Byte 4 has remaining bits : 34 to 41. So total bits for time value is 42 bits, packed as above. I need to compute epoch value coming out of these 42 bits. How do I do it? I have done something like this but not sure it gives me correct value: typedef struct P_HEADER { unsigned int tmuNumber : 21; unsigned int time1 : 10; // Bits 6,7 from Byte-3 + 8 bits from Byte-4 unsigned int time2 : 32; // 32 bits: Bytes 5,6,7,8 unsigned int traceKey : 32; } __attribute__((__packed__)) P_HEADER; Then in the code : P_HEADER *header1; //get input string in hexa,etc..etc.. //parse the input with the header as : header1 = (P_HEADER *)inputBuf; // then print the header1->time1, header1->time2 .... long ttime = header1->time1|header1->time2; //?? is this the way to get values out? Any hint tip will be appreciated. Environment is : gcc 4.1, Linux Thanks in advance.

• Kodak Scanner Software Issue 0xc0000005

  - by Andrew

  I am trying to be able to use a program called Kodak Smart Touch, but just today I have experienced an error preventing it from opening. The scanner is a business class scanner, an i2900. It comes with a small program called Kodak Smart Touch. This program allows you to select and customize a number of presets on the front panel and automatically create/save scanned files, etc. I was running a backup with Aomei Backupper at the time, and I wanted to scan a file. I tried to scan as normal, but right at the end the program quit with an error. Now, whenever I try to start Smart Touch, even not running the backup and with Aomei uninstalled, the following error pops up: Title of message: KSSCFG (version 1.7.15.121102) has stopped working. Body: See (path name) for more information. When I go to the path in the error message, there are two files, ERRORLOG.txt and KSSCFG.dmp. The error log says, "KSSCFG (version 1.7.15.322.121102) case an Access Violation(0xc0000005). Error occur at 2014/06/11 21:37:54 Operation System: Windows 7 64bits (6.1.7601) processor(s) type AMD x86 or x64" The dump file can be downloaded here: http://l.bitcasa.com/yzbtv1VV Opening it with a hex editor yields very little of use, but I do have an internal commandline utility that may help: http://l.bitcasa.com/cTXvAsst I've already uninstalled and reinstalled all the kodak software several times to no avail. What is really odd is that the TWAIN and ISIS drivers work fine through another scanning program. I am at my wit's end, and I have no idea what to do next. Thanks.

• Primary IDE Channel: Ultra DMA Mode 5 >> PIO Mode

  - by Wesley

  Hi, my netbook was having huge audio lag and just abnormally slow processing. After doing some searching on the internet, I found out that I needed to uninstall/reinstall the Primary IDE Channel found under the IDE controller section in the Device Manager. I would then set the Transfer Mode to DMA if available and everything would be great. For a period of time, I would see that "Ultra DMA Mode 5" was the current transfer mode, but every so often, it'd revert back to "PIO Mode", which is when it's really laggy. What can I do to prevent the Primary IDE Channel to revert from Ultra DMA Mode to PIO Mode? Also, my netbook has BSODed a few times when it is in PIO Mode, without any real explanation. I have a Samsung N120. Specs are as follows: http://www.samsung.com/ca/consumer/office/mobile-computing/netbook/NP-N120-KA01CA/index.idx?pagetype=prd_detail&tab=spec&fullspec=F. Only difference is that I have upgraded to 2.0 GB of DDR2 RAM. EDIT: For all who are looking for an answer to this problem, click the link in Kythos's answer and look at number 6 (Re-enable DMA using the Registry Editor). This always works for me now. If on reboot, you seem to only have a black screen after XP is loading, just wait... it is still loading and will show signs of life after 2-3 minutes.
