• SQL Server Express Profiler

  - by David Turner

  During a recent project, while waiting for our Development Database to be provisioned on the clients corporate SQL Server Environment (these things can sometimes take weeks or months to be setup), we began our initial development against a local instance on SQL Server Express, just as an interim measure until the Development database was live.  This was going just fine, until we found that we needed to do some profiling to understand a problem we were having with the performance of our ORM generated Data Access Layer.  The full version of SQL Server Management Studio includes a profiler, that we could use to help with this kind of problem, however the Express version does not, so I was really pleased to find that there is a freely available Profiler for SQL Server Express imaginatively titled ‘SQL Server Express Profiler’, and it worked great for us.  http://sites.google.com/site/sqlprofiler/

• RIA Services and Validation

  Earlier today, my SilverlightTV recording on RIA Services and Validation went online. I used validation as a feature area to focus on this first recording on RIA Services, because I think it illustrates both the RIA Services value proposition and key elements of the vision around the project in a very direct manner. Specifically: Focus on end-to-end solutions for data scenarios. It is not sufficient to just address querying data or submitting some changes, but about providing the infrastructure...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• today's multi-device world for web development

  - by paul smith

  With the huge explosion of mobile devices and addition of HTML5/CSS3, there seems to be a shift towards "responsive" designs (i.e., adapting to smaller screen sizes) which seems to be achieved using CSS3's Media Queries. My question is, given the current need of adapting to both desktop and mobile, is it common practice to actually organize two versions of your website (one for desktop and one for mobile)? Or is there just one version with different css files for targeting different devices and screens? Handling just cross-browser (ie6, ff3, opera9, etc...) HTML4/5, CSS2/3 was already hard enough, but now we're expected to handle cross-device (phone, tablet, etc...) as well, so my assumption is company's would create a separate project for mobile and redirect based on the user agent, but this is just a guess.

• Hack an Old Hardcover Book into a Reading Light

  - by Jason Fitzpatrick

  If you’re looking for a clever way to conceal a reading lamp on your bedside table, this hardcover-to-book-light conversion is just the ticket. For this project you’ll be hollowing out a hardcover book and replacing the guts with a wooden frame and a strip of cool-running and efficient LED lights. You’ll need some very basic wood working and soldering skills and an afternoon or two (mostly consumed, as the author notes, by waiting for glue to dry). Check out the video below to see the full build: Hit up the link below for a full parts list and additional building tips.

• I need to hire a web developer but I'm not sure which qualifications/skills they should have to do what I see in my head. Any help?

  - by Beau

  I'm looking to develop a simple image editor wherein a user can cycle through multiple layers (6-10) of images to develop a unique avatar. For example, the initial image layer will be a 2D character of their choice, mostly void of any accessories. The next image layer would be a shirt, another pants, another jewelry etc. I like the idea of frontend HTML5 so it can be a web app compatible across most platforms, but I'm lost on the backend requirements of such a project. #noob Any help would be greatly appreciated.

• 2D Tile-based terrian generation

  - by a240

  As a summer project I decided it would be fun to make a flash game. Right now I'm going for something like the look of http://www.terraria.org/. It's been a lot of fun, but today I've hit a snag. I need a way to generate my worlds. I've read up Perlin Noise ( http://freespace.virgin.net/hugo.elias/models/m_perlin.htm ) as a possibility, but I my attempts have given me sporadic looking results. What are some techniques used to generate these 2D tile-based worlds? Ideally I would like to be able to generate mountains, plains, and caves.

• how to start fixing bugs in open source softwares

  - by suryak

  I a student and have good knowledge in C programming and like to contribute any open source project which is developed in C. I searched sourceforge and selected 7-Zip because its widely used one and developed using C. I thought to start first by fixing bugs (which was suggested by many people in their websites) and gone through few bugs but couldn't understand how to respond to them and how to start fixing them.. I didn't understand anything. Could you please explain how to approach this.. I have even gone through some files in the source code which I downloaded but didn't understood anything. Please help me!

• Which programming career path fits my terms? [closed]

  - by Goward Gerald

  I am sick and tired of my enterprise development job, I need some programming direction like this: Demanded in jobs-market Demanded in freelance market Can use Ubuntu as development environment Not enterprise. Standalone, mobile, web-development, anything, just not enterprise. Basically, I need a programming direction which doesn't need 20 developers, terribly big databases systems and long going projects with intense long-term support, I don't want enterprise job where a lot of people are working on one terribly big project and do modules to it all day long. Instead, I need something where: Projects change pretty often Projects are little, or medium-sized (in terms of code, modules and people working on it) but still not enterprise-sized Possible for freelance, solo-development, or at least requires a team of 3-4 programmers. Not like in enterprise where you feel like a drop in the sea with your 50 classes while system itself has hundreds of classes. Suggestions please?

• Exporting an animated FBX to XNA? (in 3DS Max)

  - by Itamar Marom

  I'm now working on an XNA 3D game, and I want to add animated models in it. I came across this example. I see there is one FBX file and a few texture files in the content project, and that in the code you can choose which "take" to play. In this code it is "Take_001". Please tell me: When I create and animate my own 3D model in 3DS Max (2012, since I was told it's only possible in this version), how can I define those takes? plus, are any configurations need to be made when exporting FBX from 3DS Max to XNA? Thank you.

• Breaking up a large PHP object used to abstract the database. Best practices?

  - by John Kershaw

  Two years ago it was thought a single object with functions such as $database->get_user_from_id($ID) would be a good idea. The functions return objects (not arrays), and the front-end code never worries about the database. This was great, until we started growing the database. There's now 30+ tables, and around 150 functions in the database object. It's getting impractical and unmanageable and I'm going to be breaking it up. What is a good solution to this problem? The project is large, so there's a limit to the extent I can change things. My current plan is to extend the current object for each table, then have the database object contain these. So, the above example would turn into (assume "user" is a table) $database->user->get_user_from_id($ID). Instead of one large file, we would have a file for every table.

• Android how to get opengl 3D coordinates in ontouch event

  - by Sandy

  I created a cube in opengl and it rotates in ontouch event. To to this I created a CustomSurfaceView as follows public class CustomSurfaceView extends GLSurfaceView { @Override public boolean onTouchEvent(MotionEvent e) { float x = e.getX() float y = e.getY(); } } Here x and y are screen coordinates. How can I get 3D coordinated from this? I have already looked gluProject and NeHe. But I dont know how to implement this in my project, it shows that there is no GLdouble,GLfloat class.

• Raspberry Pi + Azure + Mobile App

  - by Richard Jones

  Ongoing project idea. So this is of long running personal interest to build a Mobile App that shows you a push notification/pop up alert, when anyone calls your house phone. So I've taken delivery of a Raspberry Pi. I've ordered a new Crucible Technology Caller ID Box. (arriving soon). I have been writing/learning Python to implement the Listener software. This will in turn push xml messages up to Azure for final delivery via push notifications to an App. iOS app already written to receive the notifications/allow address book additions made up from phone numbers from incoming calls. So this is fusion, R-Pi, Azure, Hardware and iOS. Details to follow as this plan unfolds.

• Unobtrusive Maximum Input Lengths with JQuery and FluentValidation

  - by Steve Wilkes

  If you use FluentValidation and set a maximum length for a string or a maximum  value for a numeric property, JQuery validation is used to show an error message when the user inputs too many characters or a numeric value which is too big. On a recent project we wanted to use input’s maxlength attribute to prevent a user from entering too many characters rather than cure the problem with an error message, and I added this JQuery to add maxlength attributes based on JQuery validation’s data- attributes. $(function () { $("input[data-val-range-max],input[data-val-length-max]").each(function (i, e) { var input = $(e); var maxlength = input.is("[data-val-range-max]") ? input.data("valRangeMax").toString().length : input.data("valLengthMax"); input.attr("maxlength", maxlength); }); }); Presto!

• Cheaper alternatives to 99Designs.com (outsource CSS design)

  - by Chris Smith

  I'm designing my own website as a side project and I want the site to look professional. (Read, not designed by a programmer.) I don't mind spending a little money to have a professional do it, but design sites like 99designs.com cost way to much. (~$500+) Is there a cheaper (~$100 - $200) alternative for getting a designer to improve an existing site? (Things like updating the CCS or suggesting better ways for laying out the navigation.) Or is my best bet trying to pick up a freelancer on Craigslist?

• How can a load and play an .x model using vertex animation in XNA?

  - by Christian

  From a game I developed years ago, I still have character models that my former 3D engine designer created and that I'd like to reuse in a Windows Phone project now. However, the files are in DirectX format (.x) containing keyframe animation only. No bones. No skeleton. There are a lot of animation keys defined on several frames to animate the characters. I don't quite understand how that works, to be frankly. However, I did a lot of research regarding a possible way of getting the characters animated via XNA on Windows Phone and all I found are hints that it is generally possible but not supported. Possibly by implementing own Content Importers and Processors. I didn't find anyone who successfully did something like that yet. How should I go about loading and displaying these models in XNA?

• Is hierarchical product backlog a good idea in TFS 2012-2013?

  - by Matías Fidemraizer

  I'd like to validate I'm not in the wrong way. My team project is using Visual Studio Scrum 2.x. Since each area/product has a lot of kind of requirements (security, user interface, HTTP/REST services...), I tried to manage this creating "parent backlogs" which are "open forever" and they contain generic requirements. Those parent backlogs have other "open forever" backlogs, and/or sprint backlogs. For example: HTTP/REST Services (forever) ___ Profiles API (forever) ________ POST profile (forever) _______________ We need a basic HTTP/REST profiles' API to register new user profiles (sprint backlog) Is it the right way of organizing the product backlog? Note: I know there're different points of view and that would be right for some and wrong for others. I'm looking for validation about if this is a possible good practice on TFS with Visual Studio Scrum.

• What''s easy extensible technique to store game data?

  - by Miro

  I'm looking for library/technique for storing my game resources - levels, object (effects,world info), items(price,effects,...), NPC(visual info, behavior), everything except graphics/audio stuff. I've seen lua used for Awesome WM configuration. protobuf looks good, but it seems to be designed for network communication. I've tried to write my own parser, but as the project grows it's more and more harder to manage it and catch all the bugs. My requiremets: stability easy extension of data without need to convert older versions to newer good(don't have to be the best) performance of loading not much coding not XML!

• Do you think code is self documenting?

  - by Desolate Planet

  This is a question that was put to me many years ago as a gradute in a job interview and it's nagged at my brain now and again and I've never really found a good answer that satisfied me. The interviewer in question was looking for a black and white answer, there was no middle ground. I never got the chance to ask about the rationale behind the question, but I'm curious why that question would be put to a developer and what you would learn from a yes or no answer? From my own point of view, I can read Java, Python, Delphi etc, but if my manager comes up to me and asks me how far along in a project I am and I say "The code is 80% complete" (and before you start shooting me down, I've heard this uttered in a couple of offices by developers), how exactly is that self documenting? Apologies if this question seems strange, but I'd rather ask and get some opinions on it to gain a better understanding of why it would be put to someone in an interview.

• initial Class design: access modifiers and no-arg constructors

  - by yas

  Context: Student working through Class design in personal/side project for Summer. I've never written anything implemented by others or had to maintain code. Trying to maximize encapsulation and imagining what would make code easy to maintain. Concept: Tight/Loose Class design where Tight and Loose refer to access modifiers and constructors. Tight: initially, everything, including setters, is private and a no-arg constructor is not provided (only a full constructor). Loose: not Tight Exceptions: the obvious like toString Reasoning: If code, at the very beginning, is tight, then it should be guaranteed that changes, with respect to access/creation, should never damage existing implementations. The loosening of code happens incrementally and must be thought through, justified, and safe (validated). Benefit: Existing implementing code should not break if changes are made later. Cost: Takes more time to create. Since this is my own thinking, I hope to get feedback as to whether I should push to work this way. Good idea or bad idea?

When somebody downloads the project, I want to take that image of an orange and put it in a folder called fruit on their desktop. Whenever i export my game it can't read the images anymore which is wierd so I prefer to try this method. Just like minecraft has its' stuff in %Appdata%, I want to put a folder with my images the game uses on the desktop. There isn't any errors, I'm just asking how do i do this.

• What's the DCPU-16 thing all about?

  - by ChrisRamakers

  Ever since Notch (of Minecraft fame) announced his next project will include programmable 16bit cpu's ingame everybody seems to want to write VM's for the spec notch has written up. I've seen em written in C, C++, go, javascript, coffeescript, ... Can anyone enlighten me what's so special about the spec notch wrote up or is it just that it's the first game that actually contains a CPU ingame that you can do whatever you want with? It sparked my curiosity but I fail to grasp the thing that makes it so special suddenly everybody needs to write up code for it?
