• Code review recommendations and Code Smells

  - by Michael Freidgeim

  Some time ago Twitter told that I am similar to Boris Lipschitz . Indeed he is also .Net programmer from Russia living in Australia. I‘ve read his list of Code Review points and found them quite comprehensive. A few points  were not clear for me, and it forced me for a further reading.In particular the statement “Exception should not be used to return a status or an error code.” wasn’t fully clear for me, because sometimes we store an exception as an object with all error details and I believe it’s a valid approach. However I agree that throwing exceptions should be avoided, if you expect to return error as a part of a normal flow. Related link: http://codeutopia.net/blog/2010/03/11/should-a-failed-function-return-a-value-or-throw-an-exception/ Another point slightly puzzled me“If Thread.Sleep() is used, can it be replaced with something else, ei Timer, AutoResetEvent, etc” . I believe, that there are very rare cases, when anyone using Thread.Sleep in any production code. Usually it is used in mocks and prototypes.I had to look further to clarify “Dependency injection is used instead of Service Location pattern”.Even most of articles has some preferences to Dependency injection, there are also advantages to use Service Location. E.g see http://geekswithblogs.net/KyleBurns/archive/2012/04/27/dependency-injection-vs.-service-locator.aspx. http://www.cookcomputing.com/blog/archives/000587.html  refers to Concluding Thoughts of Martin Fowler The choice between Service Locator and Dependency Injection is less important than the principle of separating service configuration from the use of services within an applicationThe post had a link to excellent article Code Smells of Jeff Atwood, but the statement, that “code should not pass a review if it violates any of the  code smells” sound too strict for my environment. In particular, I disagree with “Dead Code” recommendation “Ruthlessly delete code that isn't being used. That's why we have source control systems!”. If there is a chance that not used code will be required in a future, it is convenient to keep it as commented or #if/#endif blocks with appropriate explanation, why it could be required in the future. TFS is a good source control system, but context search in source code of current solution is much easier than finding something in the previous versions of the code.I also found a link to a good book “Clean Code.A.Handbook.of.Agile.Software”

  I'm trying to read The Art of Assembly Language as per this answer on Stack Overflow. When I open it on my Ubuntu 12.04 box, it looks like this: I haven't tested it on another machine, but this can't be intentional. What is going on, and how can I fix it? Edit: The above screenshot is from Chrome. It look like this in Evince: Still squished and hardly readable, but better. Is there anything I can do to fix it?

• AdBlock users statistics

  - by DataSmarter

  Are there statistics of internet users that use AdBlock or other ad blocking plug-ins? Are there some statistical breakdown, for example, per country (I assume it must vary a lot)? I was unable to google the information I am looking for. The reason I am asking is because I have just signed up for the "Amazon Partners" program and see that this affiliate program is listed on the AdBlock blacklist.

• How do you calculate UVW coordinates?

  - by Jenko

  I'm working on a 3d engine and I'm calculating UVT coordinates, where U and V represent pixels on the texture measured in 0-1, and T is: T = perspective / Z But I'm trying to use this perspective-correct triangle rasteriser, which requires a W, per vertex. How do I calculate the W for each vertex for the drawPerspectiveTexturedPolygon() function? Hint: The code comments refer to W as the "homogenous coordinate" ... does that mean anything?

• How to implement efficient Fog of War?

  - by Cambrano

  I've asked a question how to implement Fog Of War(FOW) with shaders. Well I've got this working. I use the vertex color to identify the alpha of a single vertex. I guess the most of you know what the FOW of Age of Empires was like, anyway I'll shortly explain it: You have a map. Everything is unexplored(solid black / 100% transparency) at the beginning. When your NPC's / other game units explore the world (by moving around mostly) they unshadow the map. That means. Everything in a specific radius (viewrange) around a NPC is visible (0%transparency). Anything that is out of viewrange but already explored is visible but shadowed (50% transparency). So yeah, AoE had relatively huge maps. Requirements was something around 100mhz etc. So it should be relatively easy to implement something to solve this problem - actually. Okay. I'm currently adding planes above my world and set the color per vertex. Why do I use many planes ? Unity has a vertex limit of 65.000 per mesh. According to the size of my tiles and the size of my map I need more than one plane. So I actually need a lot of planes. This is obviously pita for my FPS. Well so my question is, what are simple (in sense of performance) techniques to implement a FOW shader? Okay some simplified code what I'm doin so far: // Setup for (int x = 0; x < (Map.Dimension/planeSize); x++) { for (int z = 0; z < (Map.Dimension/planeSize); z++) { CreateMeshAt(x*planeSize, 3, z*planeSize) } } // Explore (is called from NPCs when walking for example) for (int x = ((int) from.x - radius); x < from.x + radius; x ++) { for (int z = ((int) from.z - radius); z < from.z + radius; z ++) { if (from.Distance(x, 1, z) > radius) continue; _transparency[x/tileSize, z/tileSize] = 0.5f; } } // Update foreach(GameObject plane in planes){ foreach(Vector3 vertex in vertices){ Vector3 worldPos = GetWorldPos(vertex); vertex.Color = new Color(0,0,0, _transparency[worldPos.x/tileSize, worldPos.z/tileSize]); } } My shader just sets the transparency of the vertex now, which comes from the vertex color channel

• Smoothing found path on grid

  - by Denis Ermolin

  I implemented several approaches such as A* and Potential fields for my tower defense game. But I want smooth paths, first I tried to find path on very small grid ( 5x5 pixels per tile) but it is extremly slow. I found nice video showing an RTS demo where paths are found on big grid but units dont move from each cell's center to center. How do I implement such behavior? Some examples would be great.

• The Single Most Important Factor For High Search Engine Rankings

  I bet most people will not believe me if I said that there is just one single most important factor when it comes to SEO because the forums are filled with advice, there are $1,000 courses teaching SEO and companies charge $5,000 or more per month for SEO services. But after 10 years as an Internet marketer, I can confidently say that the most important factor is: LINKS!

• What is the diffference between "data hiding" and "encapsulation"?

  - by john smith optional

  I'm reading "Java concurrency in practice" and there is said: "Fortunately, the same object-oriented techniques that help you write well-organized, maintainable classes - such as encapsulation and data hiding -can also help you crate thread-safe classes." The problem #1 - I never heard about data hiding and don't know what it is. The problem #2 - I always thought that encapsulation is using private vs public, and is actually the data hiding. Can you please explain what data hiding is and how it differs from encapsulation?

• Cannot get Virtualbox to install properly on Ubuntu 12.04

  - by lopac1029

  I cannot get Virtualbox to install properly on my 12.04. I first went with a manual install for the .deb from the old builds section of the Virtualbox page. That .deb opened up the Software Center and installed. Then I got the error coming up of VT-x/AMD-V hardware acceleration is not available on your system. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot. which I can only assume was due to my Ubuntu version being 32-bit (System Details - Overview - OC type: 32-bit, right?) So I followed these instructions to remove the .deb manually, restarted my laptop, and then FOUND the actual Virtualbox install in the Software Center and installed from that (assuming it would give me the correct version I need for my system) So after all that (and then some), I'm still getting the same error when I connect to my new job's project in Virtualbox. Can anyone point me in the right direction of what to do here? This is the first time I've ever worked with Virtualbox, and no one at this company is using Ubuntu, so I'm on my own here.

  BPM Process Accelerator Packs – Update | Pat Shepherd Architect Pat Shepherd shares several resources relevant to the new Oracle Process Accelerators for Oracle Business Process Management. Oracle BI EE Management Pack Now Available for Oracle Enterprise Manager 12cR2 | Mark Rittman A handy and informative overview from Oracle ACE Director Mark Rittman. WebSockets on WebLogic Server | Steve Button "As there's no standard WebSocket Java API at this point, we've chosen to model the API on the Grizzly WebSocket API with some minor changes where necessary," says James "Buttso" Buttons. "Once the results of JSR-356 (Java API for WebSocket) becomes public, we'll look to implement and support that." Oracle Reference Architecture: Software Engineering This document from the IT Strategies from Oracle library focuses on integrated asset management and the need for efffective asset metadata management to insure that assets are properly tracked and reused in a manner that provides a holistic functional view of the enterprise. The tipping point for cloud management is nigh | Cloud Computing - InfoWorld "Businesses typically don't think too much about managing IT resources until they become too numerous and cumbersome to deal with on an ad hoc basis—a point many companies will soon hit in their adoption of cloud computing." — David Linthicum DevOps Basics: Track Down High CPU Thread with ps, top and the new JDK7 jcmd Tool | Frank Munz "The approach is very generic and works for WebLogic, Glassfish or any other Java application," say Frank Munz. "UNIX commands in the example are run on CentOS, so they will work without changes for Oracle Enterprise Linux or RedHat. Creating the thread dump at the end of the video is done with the jcmd tool from JDK7." Frank has captured the process in the posted video. OIM 11g R2 UI customization | Daniel Gralewski "OIM user interface customizations are easier now, and they survive patch applications--there is no need to reapply them after patching," says Fusion Middleware A-Team member Daniel Gralewski. "Adding new artifacts, new skins, and plugging code directly into the user interface components became an easier task." Daniel shows just how easy in this post.

• Backup Azure Tables with the Enzo Backup API

  - by Herve Roggero

  In case you missed it, you can now backup (and restore) Azure Tables and SQL Databases using an API directly. The features available through the API can be found here: http://www.bluesyntax.net/backup20api.aspx and the online help for the API is here: http://www.bluesyntax.net/EnzoCloudBackup20/APIIntro.aspx. Backing up Azure Tables can’t be any easier than with the Enzo Backup API. Here is a sample code that does the trick: // Create the backup helper class. The constructor automatically sets the SourceStorageAccount property StorageBackupHelper backup = new StorageBackupHelper("storageaccountname", "storageaccountkey", "sourceStorageaccountname", "sourceStorageaccountkey", true, "apilicensekey"); // Now set some properties… backup.UseCloudAgent = false;                                       // backup locally backup.DeviceURI = @"c:\TMP\azuretablebackup.bkp";    // to this file backup.Override = true; backup.Location = DeviceLocation.LocalFile; // Set optional performance options backup.PKTableStrategy.Mode = BSC.Backup.API.TableStrategyMode.GUID; // Set GUID strategy by default backup.MaxRESTPerSec = 200; // Attempt to stay below 200 REST calls per second // Start the backup now… string taskId = backup.Backup(); // Use the Environment class to get the final status of the operation EnvironmentHelper env = new EnvironmentHelper("storageaccountname", "storageaccountkey", "apilicensekey"); string status = env.GetOperationStatus(taskId);   As you can see above, the code is straightforward. You provide connection settings in the constructor, set a few options indicating where the backup device will be located, set optional performance parameters and start the backup. The performance options are designed to help you backup your Azure Tables quickly, while attempting to keep under a specific threshold to prevent Storage Account throttling. For example, the MaxRESTPerSec property will attempt to keep the overall backup operation under 200 rest calls per second. Another performance option if the Backup Strategy for Azure Tables. By default, all tables are simply scanned. While this works best for smaller Azure Tables, larger tables can use the GUID strategy, which will issue requests against an Azure Table in parallel assuming the PartitionKey stores GUID values. It doesn’t mean that your PartitionKey must have GUIDs however for this strategy to work; but the backup algorithm is tuned for this condition. Other options are available as well, such as filtering which columns, entities or tables are being backed up. Check out more on the Blue Syntax website at http://www.bluesyntax.net.

• Installed Sun Java 6 - configuration problem when running as sudo

When I run it as sudo, I am told that JAVA_HOME is not correct and it doesn't even start the installer - shouldn't this be coming from /etc/profile like it is for my normal user?

• Coordinate based travel through multi-line path over elapsed time

  - by Chris

  I have implemented A* Path finding to decide the course of a sprite through multiple waypoints. I have done this for point A to point B locations but am having trouble with multiple waypoints, because on slower devices when the FPS slows and the sprite travels PAST a waypoint I am lost as to the math to switch directions at the proper place. EDIT: To clarify my path finding code is separate in a game thread, this onUpdate method lives in a sprite like class which happens in the UI thread for sprite updating. To be even more clear the path is only updated when objects block the map, at any given point the current path could change but that should not affect the design of the algorithm if I am not mistaken. I do believe all components involved are well designed and accurate, aside from this piece :- ) Here is the scenario: public void onUpdate(float pSecondsElapsed) { // this could be 4x speed, so on slow devices the travel moved between // frames could be very large. What happens with my original algorithm // is it will start actually doing circles around the next waypoint.. pSecondsElapsed *= SomeSpeedModificationValue; final int spriteCurrentX = this.getX(); final int spriteCurrentY = this.getY(); // getCoords contains a large array of the coordinates to each waypoint. // A waypoint is a destination on the map, defined by tile column/row. The // path finder converts these waypoints to X,Y coords. // // I.E: // Given a set of waypoints of 0,0 to 12,23 to 23, 0 on a 23x23 tile map, each tile // being 32x32 pixels. This would translate in the path finder to this: // -> 0,0 to 12,23 // Coord : x=16 y=16 // Coord : x=16 y=48 // Coord : x=16 y=80 // ... // Coord : x=336 y=688 // Coord : x=336 y=720 // Coord : x=368 y=720 // // -> 12,23 to 23,0 -NOTE This direction change gives me trouble specifically // Coord : x=400 y=752 // Coord : x=400 y=720 // Coord : x=400 y=688 // ... // Coord : x=688 y=16 // Coord : x=688 y=0 // Coord : x=720 y=0 // // The current update index, the index specifies the coordinate that you see above // I.E. final int[] coords = getCoords( 2 ); -> x=16 y=80 final int[] coords = getCoords( ... ); // now I have the coords, how do I detect where to set the position? The tricky part // for me is when a direction changes, how do I calculate based on the elapsed time // how far to go up the new direction... I just can't wrap my head around this. this.setPosition(newX, newY); }

• Creating a Strong Bridge to the Post PC World

  - by Webgui

  Moving from location to location requires strong roads.  When crossing a barrier though, like a body of water or valley, we are required to build a strong bridge to get us from point A to point B in a way that is fast, safe, and easy.Yet we are not talking here about driving a car or riding a bus.  As we in the computing world are evidencing the move to the post-PC era, modernizing and migrating legacy applications to harness the power of HTML5 web, cloud and mobile is one of the most difficult challenges enterprises have faced.  Constant technological changes have weakened the business value of legacy systems, which have been developed over the years through huge investments.  There are several risks of course in this move.  Do you choose to simply rewrite code of legacy apps and transform them to HTML5 one by one?  This is quite expensive (according to research firm Gartner, the cost is $6 - $26 per line of code).  Of course, the pace of the rewriting process is very slow – around 170 lines per day for each developer – which slows down business productivity in a world in which no organization can afford to fall behind.  Other questions include whether the new cloud-based apps will have the same functionality as the trusted applications that worked for you for years.  How will the user experience be affected?  And of course, what about data security?  So we are faced with the challenge of building a sturdy bridge to stabilize our move in order to allow us to confidently and easily move our legacy applications into the post-PC era.   We at Gizmox are excited to release the first downloadable Community Technology Preview (CTP) of our Instant CloudMove Transposition Studio.Developers: To download the tool, and try it out for yourself, please visit http://www.visualwebgui.com/download.aspx.The CTP is the first and only tool-based solution allowing any Microsoft Visual Studio developer to extend VB6 and .NET enterprise client/server applications into HTML5 web, cloud and mobile applications, including the ability to upgrade their code and UI while doing so.   It is the only solution to fully replicate enterprise desktop applications behavior in the post-PC era.  With Instant CloudMove, the transposed application is available on any mobile or tablet device, browser and across any client operating system. Moreover, the extended application logic and data remains on the server behind the fire-wall and therefore the application’s front end is secured-by-design.   We would love for you to try out the tool for yourselves and let us know what you think.  How are you finding the move?

• How do I implement collision detection with a sprite walking up a rocky-terrain hill?

  - by detectivecalcite

  I'm working in SDL and have bounding rectangles for collisions set up for each frame of the sprite's animation. However, I recently stumbled upon the issue of putting together collisions for characters walking up and down hills/slopes with irregularly curved or rocky terrain - what's a good way to do collisions for that type of situation? Per-pixel? Loading up the points of the incline and doing player-line collision checking? Should I use bounding rectangles in general or circle collision detection?
