• Trade off: Lower the number of URLs in sitemap from 43k to 23k or update the sitemap.xml only weekly basis

  - by Tobias

  we rewrote the sitemap creation process. Now the sitemap contains 43.000 URLs. 20k more than before. We have daily changing in URLs. The script that is creating the complete sitemap takes more than 30h. So we can not build it every day. Lets say that increasing the speed of the script is not possible. What should I do? A: Stay with the 23k URLs and update it daily B: Increase number of URLs to 43k and update it weekly

• Managed code and the Shell – Do?

  Back in 2006 I wrote a blog post titled: Managed code and the Shell – Don't!. Please visit that post to see why that advice was given.The crux of the issue has been addressed in the latest CLR via In-Process Side-by-Side Execution. In addition to the MSDN documentation I just linked, there is also an MSDN article on the topic: In-Process Side-by-Side.Now, even though the major technical impediment seems to be removed, I don’t know if Microsoft is now officially supporting managed extensions to the shell. Either way, I noticed a CodePlex project that is marching ahead to enable exactly that: Managed Mini Shell Extension Framework. Not much activity there, but maybe it will grow once .NET 4 is released... Comments about this post welcome at the original blog.

• Funny statements, quotes, phrases, errors found on technical Books [closed]

  - by Felipe Fiali

  I found some funny or redundant statements on technical books I've read, I'd like to share. And I mean good, serious, technical books. Ok so starting it all: The .NET framework doesn't support teleportation From MCTS 70-536 Training kit book - .NET Framework 2.0 Application Development Foundation Teleportation in science fiction is a good example of serialization (though teleportation is not currently supported byt the .NET Framework). C# 3 is sexy From Jon Skeet's C# in Depth second Edition You may be itching to get on to the sexy stuff from C# 3 by this point, and I don’t blame you. Instantiating a class From Introduction to development II in Microsoft Dynamics AX 2009 To instantiate a class, is to create a new instance of it. Continue or break From Introduction to development II in Microsoft Dynamics AX 2009 Continue and break commands are used within all three loops to tell the execution to break or continue. These are just a few. I'll post some more later. Share some that you might have found too.

• Seek Steering Behavior with Target Direction for Group of Fighters

  - by SebastianStehle

  I am implementing steering algorithms with group management for spaceships (fighters). I select a leader and assign the target positions for the other spaceships based on the target position of the leader and an offset. This works well. But when my spaceships arrive they all have a different direction. I want them to keep to look in the same direction (target - start). I also want to combine this behavior with a minimum turning radius that is based on the speed. The only idea I have is to calculate a path for each spaceship with an point before the target position, so the ships have some time left to turn into the right position. But I dont know if this is a good idea. I guess there will be a lot of rare cases where this can cause a problem. So the question is, if anybody knows how to solve this problem and has some (simple code) or pseudocode for me or at least some good explanation.

• Platformer Starter Kit - Collision Issues

  - by Cyral

  I'm having trouble with my game that is based off the XNA Platformer starter kit. My game uses smaller tiles (16x16) then the original (32x40) which I'm thinking may be having an effect on collision (Being it needs to be more precise). Standing on the edge of a tile and jumping causes the player to move off the the tile when he lands. And 80% of the time, when the player lands, he goes flying though SOLID tiles in a diagonal fashion. This is very annoying as it is almost impossible to test other features, when spawning and jumping will result in the player landing in another part of the level or falling off the edge completely. The code is as follows: /// <summary> /// Updates the player's velocity and position based on input, gravity, etc. /// </summary> public void ApplyPhysics(GameTime gameTime) { float elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; Vector2 previousPosition = Position; // Base velocity is a combination of horizontal movement control and // acceleration downward due to gravity. velocity.X += movement * MoveAcceleration * elapsed; velocity.Y = MathHelper.Clamp(velocity.Y + GravityAcceleration * elapsed, -MaxFallSpeed, MaxFallSpeed); velocity.Y = DoJump(velocity.Y, gameTime); // Apply pseudo-drag horizontally. if (IsOnGround) velocity.X *= GroundDragFactor; else velocity.X *= AirDragFactor; // Prevent the player from running faster than his top speed. velocity.X = MathHelper.Clamp(velocity.X, -MaxMoveSpeed, MaxMoveSpeed); // Apply velocity. Position += velocity * elapsed; Position = new Vector2((float)Math.Round(Position.X), (float)Math.Round(Position.Y)); // If the player is now colliding with the level, separate them. HandleCollisions(); // If the collision stopped us from moving, reset the velocity to zero. if (Position.X == previousPosition.X) velocity.X = 0; if (Position.Y == previousPosition.Y) velocity.Y = 0; } /// <summary> /// Detects and resolves all collisions between the player and his neighboring /// tiles. When a collision is detected, the player is pushed away along one /// axis to prevent overlapping. There is some special logic for the Y axis to /// handle platforms which behave differently depending on direction of movement. /// </summary> private void HandleCollisions() { // Get the player's bounding rectangle and find neighboring tiles. Rectangle bounds = BoundingRectangle; int leftTile = (int)Math.Floor((float)bounds.Left / Tile.Width); int rightTile = (int)Math.Ceiling(((float)bounds.Right / Tile.Width)) - 1; int topTile = (int)Math.Floor((float)bounds.Top / Tile.Height); int bottomTile = (int)Math.Ceiling(((float)bounds.Bottom / Tile.Height)) - 1; // Reset flag to search for ground collision. isOnGround = false; // For each potentially colliding tile, for (int y = topTile; y <= bottomTile; ++y) { for (int x = leftTile; x <= rightTile; ++x) { // If this tile is collidable, ItemCollision collision = Level.GetCollision(x, y); if (collision != ItemCollision.Passable) { // Determine collision depth (with direction) and magnitude. Rectangle tileBounds = Level.GetBounds(x, y); Vector2 depth = RectangleExtensions.GetIntersectionDepth(bounds, tileBounds); if (depth != Vector2.Zero) { float absDepthX = Math.Abs(depth.X); float absDepthY = Math.Abs(depth.Y); // Resolve the collision along the shallow axis. if (absDepthY < absDepthX || collision == ItemCollision.Platform) { // If we crossed the top of a tile, we are on the ground. if (previousBottom <= tileBounds.Top) isOnGround = true; // Ignore platforms, unless we are on the ground. if (collision == ItemCollision.Impassable || IsOnGround) { // Resolve the collision along the Y axis. Position = new Vector2(Position.X, Position.Y + depth.Y); // Perform further collisions with the new bounds. bounds = BoundingRectangle; } } else if (collision == ItemCollision.Impassable) // Ignore platforms. { // Resolve the collision along the X axis. Position = new Vector2(Position.X + depth.X, Position.Y); // Perform further collisions with the new bounds. bounds = BoundingRectangle; } } } } } // Save the new bounds bottom. previousBottom = bounds.Bottom; } It also tends to jitter a little bit sometimes, I'm solved some of this with some fixes I found here on stackexchange, But Ive only seen one other case of the flying though blocks problem. This question seems to have a similar problem in the video, but mine is more crazy. Again this is a very annoying bug! Any help would be greatly appreciated! EDIT: Speed stuff // Constants for controling horizontal movement private const float MoveAcceleration = 13000.0f; private const float MaxMoveSpeed = 1750.0f; private const float GroundDragFactor = 0.48f; private const float AirDragFactor = 0.58f; // Constants for controlling vertical movement private const float MaxJumpTime = 0.35f; private const float JumpLaunchVelocity = -3500.0f; private const float GravityAcceleration = 3400.0f; private const float MaxFallSpeed = 550.0f; private const float JumpControlPower = 0.14f;

• How do engines avoid "Phase Lock" (multiple objects in same location) in a Physics Engine?

  - by C0M37

  Let me explain Phase Lock first: When two objects of non zero mass occupy the same space but have zero energy (no velocity). Do they bump forever with zero velocity resolution vectors or do they just stay locked together until an outside force interacts? In my home brewed engine, I realized that if I loaded a character into a tree and moved them, they would signal a collision and hop back to their original spot. I suppose I could fix this by implementing impulses in the event of a collision instead of just jumping back to the last spot I was in (my implementation kind of sucks). But while I make my engine more robust, I'm just curious on how most other physics engines handle this case. Do objects that start in the same spot with no movement speed just shoot out from each other in a random direction? Or do they sit there until something happens? Which option is generally the best approach?

• Can't set permissions for files on an NTFS partition

  - by ashishsony

  I remember that I was able to run a Linux .exe that was placed on an NTFS partition earlier before I installed 10.10 RC. But if I try to run it now, I can't run it as it hasn't the execution permission. The bad part is that I can't change the permissions too. I'm chmod-ding +x but no change at all with its permissions. So this seems to be a bug? Any help? Though when I put it on ext4 partition, I can set the permission. But I want to do this as I did before, right from its default NTFS location.

• Speaking at AMD Fusion conference

  - by Daniel Moth

  Next Wednesday at 2pm I will be presenting a session at the AMD Fusion developer summit in Bellevue, Washington State. For more on this conference please visit the official website. If you filter the catalog by 'Speaker Last Name' to "Moth", you'll find my talk. For your convenience, below is the title and abstract Blazing-fast code using GPUs and more, with Microsoft Visual C++ To get full performance out of mainstream hardware, high-performance code needs to harness, not only multi-core CPUs, but also GPUs (whether discrete cards or integrated in the processor) and other compute accelerators to achieve orders-of-magnitude speed-up for data parallel algorithms. How can you as a C++ developer fully utilize all that heterogeneous hardware from your Visual Studio environment? How can your code benefit from this tremendous performance boost without sacrificing your developer productivity or the portability of your solution? The answers will be presented in this session that introduces a new technology from Microsoft. Hope to see many of you there! Comments about this post welcome at the original blog.

• Hadoop and Object Reuse, Why?

  - by Andrew White

  In Hadoop, objects passed to reducers are reused. This is extremely surprising and hard to track down if you're not expecting it. Furthermore, the original tracker for this "feature" doesn't offer any evidence that this change actually improved performance (unless I missed it). It would speed up the system substantially if we reused the keys and values [...] but I think it is worth doing. This seems completely counter to this very popular answer. Is there some credence to the Hadoop developer's claim? Is there something "special" about Hadoop that would invalidate the notion of object creation being cheap?

• Slow internet browsing in Ubuntu

  - by Mark

  I have a dual boot set up with windows and ubuntu, when I'm using windows internet browsing is a lot faster than when I'm using ubuntu and I don't know why. It's like there's just a big latency rather than the maximum speed is lower, there's a big delay before anything happens when using Ubuntu, it happens with all websites all the time. I've never configured the internet connection because it just worked straight away. I have broadband connection through a router shared with some other computers, when we set up the router and internet connection everything was done with windows. Any ideas on what I could do to fix this? Thanks to anyone who replies.

• Is there really Object-relational impedance mismatch?

  - by user52763

  It is always stated that it is hard to store applications objects in relational databases - the object-relational impedance mismatch - and that is why Document databases are better. However, is there really an impedance mismatch? And object has a key (albeit it may be hidden away by the runtime as a pointer to memory), a set of values, and foreign keys to other objects. Objects are as much made up of tables as it is a document. Neither really fit. I can see a use for databases to model the data into specific shapes for scenarios in the application - e.g. to speed up database lookup and avoid joins, etc., but won't it be better to keep the data as normalized as possible at the core, and transform as required?

• Silverlight Cream Monday WP7 App Review # 2

  - by Dave Campbell

  Today's Review (alphabetic order): GooNews, Grocery Shopping List, Need for Speed, SurfCube, and United Nations News. I'm a day late if these are going to be 'Monday' posts, but there are lots of apps, lots of goodness, and lots of email, so I might try to do 2 a week, we'll see. So once again I've got a small review of 5 apps that are either on my phone or have been. Disclaimers at the end. In this Issue:   GooNews is a very cool app from Shawn Wildermuth (AgiliTrain). I don't know if he uses this as a demo during his instruction, but it definitely serves a purpose... wanna pick up the top news items from Google on a never-ending basis? ... this is it. You can add your own keyword searches, and send stories to InstaPaper or share via email. I like this because it brings me the news quickly and updated, and works great. GooNews is by AgiliTrain and is Free This was a request by the author, and actually surprised me. I'm a big one for lists, but I would have just done a OneNote list to SkyDrive and to my phone. This app is a lot more than that, but will take you some setup to make it be 'yours'. For obvious reasons, there are no unit prices on things, so you have to set that up to get some idea of the cost of what you're shopping for. But if you do that, you'll get a nice total. Lots of thought went into the various categories and you can add your own. There's a bit of animation on the category selection that's nice. He seems to have covered all the bases necessary to use this, even shopping 'plans' that can be saved, and emailing of lists. As I said, I'm more of a raw list person, but if you take the time to set this up, it should work very nicely for you. Grocery Shopping List is by Grocery Shopper and is $0.99 ($1.99 after Feb 1) with a free trial. This was my 2nd commercial game I bought, and the one I've played the most. I ran the trial, thought it worked great, and bought it. I've had a lot of fun with this... there's no gas pedal.. your foot is in the carbeurator from the GO!, and unless you wanna tap the screen and brake like a little girl, just hang onto the steering wheel (the phone), and guide your way through. Hours of fun and challenges here. I like this because it's got some challenge to it, and the cars seem to be very realistic in their reactions. Need for Speed Undercover is by Electronic Arts is $4.99 and has a free trial. SurfCube Browser is another app by the folks that did the GuitarTuner I reviewed on Monday. You have to see SurfCube to believe it. You've probably seen the YouTube video, if not check SilverlightCream number 1017. The app works very solid, and just as the video demonstrates. I downloaded and tried this, and it immediately did 2 things: bought it, and pinned it to my start page. I like this because it's fun to work with, and it works great as a browser. I'm about *this* close to replacing the IE tile on my front page with SurfCube. SurfCube Browser is by Kinabalu Innovation Limited and is $1.99 and has a free trial. Coming in with another News app is United Nations News by Justin Angel. This is definitely a news aggregator for 'grown ups'... news, photos, videos, and radio broadcsts from the international community all in one very slick app. This is an amazingly well thought-out and complete app. Even better yet, Justin has the code on CodePlex. A very well-done International news aggregator. United Nations News is by Justin Angel and is Free. A few disclaimers: Feel free to write me about your app and tell me about it. While it would be very cool to receive a whole bunch of xap files to review, at this point, for technical reasons, I'm unable to side-load my device. Since I plan on only doing this one day a week (twice if I find time), and only 5, I may never get caught up, so if you send me some info, be patient. Re: games ... remember I'm old... I'm from the era of Colossal Cave and Zork. Duke-Nukem 2D and Captain Comic were awesome. I don't own an XBOX or any other game system, so take game reviews from my perspective -- who knows, it may be refreshing :) I won't pay for an app or game just to try it. If you expect me to test-drive your app, it's going to have to have a Free Trial. I'm still playing with the format, comments are welcome. I decided I should alphabetize the list today... so there's no order implied Let me know what you think of the idea of doing reviews, or the layout/whatever, and Stay in the 'Light!

• updater stuck on downloading python files

  - by Tim

  However i am a java programmer is consider myself as a linux noob. So i could use a little help here... I am trying to update my ubuntu from version 10.04 to 12.04.1 (LTS). The downloading start and runs at around 10MB/s untill i am somewhere near 26% and the speed just drops to 0. I figured i could use the command "do-release-update" so i could see what it was doing. Again the same occured: the downloading stucked on 26% at "http://nl.archive.ubuntu.com/ubunutu/ precise/main python-qt4 1386 4.9.1-2ubuntu1". It says it downloaded 41% of that file/package. It also tries another wget on the same file every X seconds. Help? Greetings Tim, Holland.

• Introducing the Documentation Workflows

  - by Owen Allen

  The how-to documents  provide end to end examples of specific features, such as creating a new zone or discovering a new system. We are enhancing the individual how-tos with documents called Workflows. These workflows are each built around procedural flowcharts that show these larger and more complex tasks. The workflow indicates which how-tos or other workflows you should follow to complete a more complex process, and give you a flow for planning the execution of a process. Over the coming days I'll highlight each of these workflows, and talk about the tasks that each one guides you through.

• Ubuntu took away permissions from my Data partition

  - by RobinJ

  The pangolin has struck again. The bug of the day for today is Ubuntu taking away my permissions on my Data partition (NTFS). One moment everything worked fine, the next moment I couldn't chmod anything anymore. chown throws no errors or warnings at all, but nothing has changed either. chmod keeps saying Operation not permitted. I've been messing around with /etc/fstab as suggested by other answers on AskUbuntu, but none of them seem to have the desired effect. This is my current line: UUID=25D7D681409A96B7 /media/Data ntfs defaults,umask=000,gid=46,permissions,users,auto,exec 0 0 For reference, this is the original one: UUID=25D7D681409A96B7 /media/Data ntfs defaults,umask=007,gid=46 0 0 (right after the problem started occuring) What do I need to do so I am the owner of my own hard drive again? I want to be able to just use chmod and chown (without sudo) without being told that some mysterious alien has taken over control of my Data partition. I can still read and write, but execution permissions seem to be the problem.

• Installation of Ubuntu 13.04 seems to take forever

  - by Michel

  I am about to install Ubuntu 13.04 on my AMD x64 machine and the installation of the lib packages seems to take forever. Is that a known issue? I know that it might take some time when checking to download packages from the Internet but this went through very fast. In the terminal-like view I can see, the system is just unpacking, installing, configuring etc. in a quite slow way. In the opening screen it reads: It just takes a few minutes (or something close to that). Again: Is that a normal behavior or am I doing something wrong and what could I do to speed up the process in case I'm running an installation again on another system?

• Narrow-phase collision detection algorithms

  - by Marian Ivanov

  There are three phases of collision detection. Broadphase: It loops between all objecs that can interact, false positives are allowed, if it would speed up the loop. Narrowphase: Determines whether they collide, and sometimes, how, no false positives Resolution: Resolves the collision. The question I'm asking is about the narrowphase. There are multiple algorithms, differing in complexity and accuracy. Hitbox intersection: This is an a-posteriori algorithm, that has the lowest complexity, but also isn't too accurate, Color intersection: Hitbox intersection for each pixel, a-posteriori, pixel-perfect, not accuratee in regards to time, higher complexity Separating axis theorem: This is used more often, accurate for triangles, however, a-posteriori, as it can't find the edge, when taking last frame in account, it's more stable Linear raycasting: A-priori algorithm, useful for semi-realistic-looking physics, finds the intersection point, even more accurate than SAT, but with more complexity Spline interpolation: A-priori, even more accurate than linear rays, even more coplexity. There are probably many more that I've forgot about. The question is, in when is it better to use SAT, when rays, when splines, and whether there is anything better.
