• w3wp.exe (ASP .Net) eating memory (2 replies)

  Hello, i'm on a VPS with Windows 2003 x64 (IIS 6.0 so) and i have a serious problem with w3wp.exe. It starts from 60 Mb and then grows until the whole avaiable RAM is used. http://img32.imageshack.us/img32/4120/w3wpgraph.png Here's an example image showing w3wp.exe private bytes and Gen 0 Heap size. They seems related, but if I use &quot;.NET CLR Memory/# Bytes in all Heaps &quot; it is much lower than priv...

• When not to use Google Web Toolkit?

  - by Jas

  I'm considering use of GWT on a major in-house web app development project, namely it's major advantage in my eyes is the cross-compilation to Javascript which would (at least theoretically) help my team reduce the size of tech stack by one. However, having been burnt before (like most devs), I would like to hear from programmers who did actually use it on any problems with GWT which would hamper, or limit, it's use within a certain problem domain. When do you not recommend using GWT, and why?

• Files not refreshing after uploaded and overwritten via ftp

  - by guisasso

  I have been having some trouble with updating my website this morning. After editing some files, in special, a css file, and uploading it to the server, i would notice that the changes wouldn't happen, as if the file had not been overwritten. File size on my local machine would be 3.244 kb and on the server 3.080 kb. Even after deleting the whole folder itself, and uploading everything again, same error. Answer: Cloudfare.

• How do you pack resources in a game when you have too many of them?

  - by ThePlan

  I've recently made a basic space invaders clone in C++ using the Allegro 5 framework. It took me a long time, but after I finished, I realized I had about 10 sprites, and 13MB worth of DLLs (Some of the people didn't even have the mingW dlls) which were making people who played the game very confused. How can I "pack" all my resources in a way that I can easily add-remove data to my game, and to reduce the size taken by the resource, basically placing them in 1 spot? I'm using codeblocks.

• What makes a project big?

  - by Jonny

  Just out of curiosity what's the difference between a small, medium and large size project? Is it measured by lines of code or complexity or what? Im building a bartering system and so far have about 1000 lines of code for login/registration. Even though there's lots of LOC i wouldnt consider it a big project because its not that complex though this is my first project so im not sure. How is it measured?

• Finding duplicate files?

  - by ub3rst4r

  I am going to be developing a program that detects duplicate files and I was wondering what the best/fastest method would be to do this? I am more interested in what the best hash algorithm would be to do this? For example, I was thinking of having it get the hash of each files contents and then group the hashes that are the same. Also, should there be a limit set for what the maximum file size can be or is there a hash that is suitable for large files?

• Configure xfce4-screenshooter settings

  - by rubo77

  xfce4-screenshooter is the standard screenshot program in XFCE on Xubuntu. How can I configure the settings about which format it saves the screenshot in and in which folder? I noticed, that my settings I made in shutter also affect the settings of xfce4-screenshooter (but not all). EDIT: The man page sais, there is an -o option to open it with an external program. How can I make this default? Then I could set there an external program, that automatically compresses the screenshot to an emailable size

• Why does my code dividing a 2D array into chunks fail?

  - by Borog

  I have a 2D-Array representing my world. I want to divide this huge thing into smaller chunks to make collision detection easier. I have a Chunk class that consists only of another 2D Array with a specific width and height and I want to iterate through the world, create new Chunks and add them to a list (or maybe a Map with Coordinates as the key; we'll see about that). world = new World(8192, 1024); Integer[][] chunkArray; for(int a = 0; a < map.getHeight() / Chunk.chunkHeight; a++) { for(int b = 0; b < map.getWidth() / Chunk.chunkWidth; b++) { Chunk chunk = new Chunk(); chunkArray = new Integer[Chunk.chunkWidth][Chunk.chunkHeight]; for(int x = Chunk.chunkHeight*a; x < Chunk.chunkHeight*(a+1); x++) { for(int y = Chunk.chunkWidth*b; y < Chunk.chunkWidth*(b+1); y++) { // Yes, the tileMap actually is [height][width] I'll have // to fix that somewhere down the line -.- chunkArray[y][x] = map.getTileMap()[x*a][y*b]; // TODO:Attach to chunk } } chunkList.add(chunk); } } System.out.println(chunkList.size()); The two outer loops get a new chunk in a specific row and column. I do that by dividing the overall size of the map by the chunkSize. The inner loops then fill a new chunkArray and attach it to the chunk. But somehow my maths is broken here. Let's assume the chunkHeight = chunkWidth = 64. For the first Array I want to start at [0][0] and go until [63][63]. For the next I want to start at [64][64] and go until [127][127] and so on. But I get an out of bounds exception and can't figure out why. Any help appreciated! Actually I think I know where the problem lies: chunkArray[y][x] can't work, because y goes from 0-63 just in the first iteration. Afterwards it goes from 64-127, so sure it is out of bounds. Still no nice solution though :/ EDIT: if(y < Chunk.chunkWidth && x < Chunk.chunkHeight) chunkArray[y][x] = map.getTileMap()[y][x]; This works for the first iteration... now I need to get the commonly accepted formula.

• CUPS - Configuring default printer options

  - by user193661

  I'm using a CUPS printer and trying to set the default options for the printer using /etc/cups/ppd and /etc/cups/printers.conf but I don't see a complete list of available options. Currently I'm trying Option page-top 2 Option page-bottom 2 Option scaling 95 My end goal is getting the printer to stop cutting off the top and bottom page content. I would like to automatically scale the content to fit on the page size being used (default "letter") if possible and if not, resume printing on another page without removing any of the content.

• Analysing Indexes - count *

  - by GrumpyOldDBA

  In my presentations on indexing I have always said that you should explore the advantages of covering your clustered index with a secondary index. In circumstances where you might want to just return values form the PK ( assuming it's your clustered index ) a secondary index will be more efficient especially when the row size is wide. Any operation on a clustered index will always return the entire row, so select ID from dbo.mytable where ID is the clustered PK integer will return not just the...(read more)

• Looking for a disk manager that has options for setting allocation sizes in paritions

  I'm looking for a GUI program that is compatible with Ubuntu 13.10 - Server X86-64 that has all the features of Gparted but also allows for setting custom allocation sizes when creating a partition. Eg: Ability to create a 4gb Fat32 parition with 32 kilobyte allocation size. Please don't suggest a terminal only application, no matter how awesome it might be, because that's not what I asked. Wow, I come off like a right up prick when I write, eh?

• Using elapsed time for SlowMo in XNA

  - by Dave Voyles

  I'm trying to create a slow-mo effect in my pong game so that when a player is a button the paddles and ball will suddenly move at a far slower speed. I believe my understanding of the concepts of adjusting the timing in XNA are done, but I'm not sure of how to incorporate it into my design exactly. The updates for my bats (paddles) are done in my Bat.cs class: /// Controls the bat moving up the screen /// </summary> public void MoveUp() { SetPosition(Position + new Vector2(0, -moveSpeed)); } /// <summary> /// Controls the bat moving down the screen /// </summary> public void MoveDown() { SetPosition(Position + new Vector2(0, moveSpeed)); } /// <summary> /// Updates the position of the AI bat, in order to track the ball /// </summary> /// <param name="ball"></param> public virtual void UpdatePosition(Ball ball) { size.X = (int)Position.X; size.Y = (int)Position.Y; } While the rest of my game updates are done in my GameplayScreen.cs class (I'm using the XNA game state management sample) Class GameplayScreen { ........... bool slow; .......... public override void Update(GameTime gameTime, bool otherScreenHasFocus, bool coveredByOtherScreen) base.Update(gameTime, otherScreenHasFocus, false); if (IsActive) { // SlowMo Stuff Elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; if (Slowmo) Elapsed *= .8f; MoveTimer += Elapsed; double elapsedTime = gameTime.ElapsedGameTime.TotalMilliseconds; if (Keyboard.GetState().IsKeyDown(Keys.Up)) slow = true; else if (Keyboard.GetState().IsKeyDown(Keys.Down)) slow = false; if (slow == true) elapsedTime *= .1f; // Updating bat position leftBat.UpdatePosition(ball); rightBat.UpdatePosition(ball); // Updating the ball position ball.UpdatePosition(); and finally my fixed time step is declared in the constructor of my Game1.cs Class: /// <summary> /// The main game constructor. /// </summary> public Game1() { IsFixedTimeStep = slow = false; } So my question is: Where do I place the MoveTimer or elapsedTime, so that my bat will slow down accordingly?

• What causes Multi-Page allocations?

  - by SQLOS Team

  Writing about changes in the Denali Memory Manager In his last post Rusi mentioned: " In previous SQL versions only the 8k allocations were limited by the ‘max server memory’ configuration option.  Allocations larger than 8k weren’t constrained." In SQL Server versions before Denali single page allocations and multi-Page allocations are handled by different components, the Single Page Allocator (which is responsible for Buffer Pool allocations and governed by 'max server memory') and the Multi-Page allocator (MPA) which handles allocations of greater than an 8K page. If there are many multi-page allocations this can affect how much memory needs to be reserved outside 'max server memory' which may in turn involve setting the -g memory_to_reserve startup parameter. We'll follow up with more generic articles on the new Memory Manager structure, but in this post I want to clarify what might cause these larger allocations. So what kinds of query result in MPA activity? I was asked this question the other day after delivering an MCM webcast on Memory Manager changes in Denali. After asking around our Dev team I was connected to one of our test leads Sangeetha who had tested the plan cache, and kindly provided this example of an MPA intensive query: A workload that has stored procedures with a large # of parameters (say > 100, > 500), and then invoked via large ad hoc batches, where each SP has different parameters will result in a plan being cached for this “exec proc” batch. This plan will result in MPA.   Exec proc_name @p1, ….@p500 Exec proc_name @p1, ….@p500 . . . Exec proc_name @p1, ….@p500 Go   Another workload would be large adhoc batches of the form: Select * from t where col1 in (1, 2, 3, ….500) Select * from t where col1 in (1, 2, 3, ….500) Select * from t where col1 in (1, 2, 3, ….500) … Go  In Denali all page allocations are handled by an "Any size page allocator" and included in 'max server memory'. The buffer pool effectively becomes a client of the any size page allocator, which in turn relies on the memory manager. - Guy Originally posted at http://blogs.msdn.com/b/sqlosteam/

• PowerPivot: editing measures when you reach 45

  - by AlbertoFerrari

  I have always been used to small fonts but now, as I am getting older, I’d better admit that a greater font is much more relaxing. Editing PowerPivot measures has always been a pain, since all you have available is a small text box and I hate to admit that I got used to leverage ZoomIt for a long time to edit measures. Today I ran into a great Windows feature that I did not know about: ctrl-wheel on the mouse inside a textbox increases the font size of the text box. It seems to work with most textboxes...(read more)

Note-- i didn't mean for a flame war in indentation -- just whether anyone else has come across tis study before? EDIT: @MaR I made a poll http://poll.fm/3d5kg
