Logging library for (c++) games

- by Klaim

I know a lot of logging libraries but didn't test a lot of them. (GoogleLog, Pantheios, the coming boost::log library...) In games, especially in remote multiplayer and multithreaded games, logging is vital to debugging, even if you remove all logs in the end. Let's say I'm making a PC game (not console) that needs logs (multiplayer and multithreaded and/or multiprocess) and I have good reasons for looking for a library for logging (like, I don't have time or I'm not confident in my ability to write one correctly for my case). Assuming that I need : performance ease of use (allow streaming or formating or something like that) reliable (don't leak or crash!) cross-platform (at least Windows, MacOSX, Linux/Ubuntu) Wich logging library would you recommand? Currently, I think that boost::log is the most flexible one (you can even log to remotely!), but have not good performance. Pantheios is often cited but I don't have comparison points on performance and usage. I've used my own lib for a long time but I know it don't manage multithreading so it's a big problem, even if it's fast enough. Google Log seems interesting, I just need to test it but if you already have compared those libs and more, your advice might be of good use. Games are often performance demanding while complex to debug so it would be good to know logging libraries that, in our specific case, have clear advantages.

Reproducible freezes with on an AMD fusion (e350) sony vaio

- by doycho

So a week ago I bought it and I've been struggling to make the Ubuntu which I installed stable. There's one thing that makes my life miserable, though. There's this easily reproducible freeze when I start some kind of video. So here is what happens: Everything works fine for some time I start vlc/mplayer/flashplayer/totem with something to watch In few minutes time I lose the sound (nothing in the logs at this point) At that time the video app instantly allocates all the memory and its CPU usage skyrockets. Total freeze. I can move the cursor around for few seconds and sometimes even switch to another app. But ultimately there comes the time I can't do anything - can't kill X with ctrl+alt+backspace (I have it enabled), can't switch to any other console (ctrl+alt+f1-6), can't connect to the machine via ssh. The only way to restart it is the ctrl+alt+SysRq+UABI magic :) What discourages me most is the fact I can't see anything in the logs. The only error I've noticed is Jun 19 17:00:37 serenity kernel: [ 1506.350676] software-center[17581]: segfault at 30 ip 00007fd3631b814c sp 00007fff18a6fa10 error 4 in libgtk-x11-2.0.so.0.2400.4[7fd362f7d000+436000]. I've been searching through the Xorg log, kernel logs, syslog. If you have any idea how I can get more debug info I'll be glad to try them. Things I've tried: Changing drivers - the open source one, the proprietary driver xorg-edgers' ppa - https://launchpad.net/~xorg-edgers/+archive/ppa changing to the last stable kernel (2.6.39) Some notes: It my be irrelevant but the sound is constantly stuttering. This probably is a separate issue though I've found that if I start more video/sound apps the freeze happens faster.

Missing X-Spam-Status header

- by Walt Stoneburner

I recently upgraded to Ubuntu 14.04.1 LTS (trusty) and have followed the directions in https://help.ubuntu.com/14.04/serverguide/mail-filtering.html and am sending and receiving mail just fine. While I do see X-Virus-Scanned headers in my messages, which suggests mail is indeed being processed, I do not see any X-Spam-Level or X-Spam-Score headers being added to messages. This makes downstream procmailrc and client-side filtering ...more difficult. While having $final_spam_destiny = D_DISCARD in /etc/amavis/conf.d/20-debian_defaults does greatly reduce spam to my inbox, I had concerns of false-positives prior to tuning and didn't know were there going, so have set it to D_PASS for the time being. This exposed the problem. I'm not sure where to look to start diagnosing the problem (otherwise I'd post a suspect configuration file). /etc/amavis/conf.d/15-content_filter_mode has the lines uncommented to enable virus and spam checks, and virus checking appears to be working according to the headers. Spam Assassin certainly seems to be starting just fine, too. SpamAssassin debug facilities: info SA info: zoom: able to use 360/360 'body_0' compiled rules (100%) SpamAssassin loaded plugins: AskDNS, AutoLearnThreshold, Bayes, BodyEval, Check, DKIM, DNSEval, FreeMail, HTMLEval, HTTPSMismatch, Hashcash, HeaderEval, ImageInfo, MIMEEval, MIMEHeader, Pyzor, Razor2, RelayEval, ReplaceTags, Rule2XSBody, SPF, SpamCop, URIDNSBL, URIDetail, URIEval, VBounce, WLBLEval, WhiteListSubject SpamControl: init_pre_fork on SpamAssassin done I've also set $log_level = 2; in /etc/amavis/conf.d/50-user and don't see any obvious errors rolling by in the logs. Q: Any recommendations of what to try next? UPDATE (it appears that I have the right setting already): /etc/amavis/conf.d$ grep sa_tag_level_deflt * 20-debian_defaults:# $sa_tag_level_deflt = 2.0; # add spam info headers if at, or above that level 20-debian_defaults:$sa_tag_level_deflt = -999; # add spam info headers if at, or above that level

Getting Started with GlassFish 4 and OEPE

- by gstachni

Oracle Enterprise Pack for Eclipse 12.1.1.2.2 introduces new support for GlassFish 4.0, the reference implementation of Java EE7. Getting started with GlassFish 4.0 in Eclipse couldn't be easier. Follow these short steps to get GlassFish 4.0 setup so you can start developing, deploying, and debugging your Java EE7 applications. Prerequisites GlassFish 4.0 Oracle Enterprise Pack for Eclipse 12.1.1.2.2+ from OTN or Eclipse Marketplace Setting up the server connection In the Servers view, click to add a New > Server . Select GlassFish 4.0 from the list of supported server configurations. Pick your GlassFish installation directory (usually <glassfish 4>/glassfish) and select your domain. After you click Finish you should now be setup to launch Glassfish 4.0 in normal and debug mode within Eclipse as well as associate projects for deployment through the Add and Remove wizard. Using GlassFish tools in Eclipse GlassFish server tools provide some useful information about your running GlassFish 4.0 environment. Resources displays current resources deployed in the domain including your JDBC Connection Pool and JDBC Resource names. I find this extra bit of information useful when working with JPA. Deployed Applications shows the current active deployments in GlassFish which can be undeployed as needed from within Eclipse. Deployed Web Services provides information about SOAP-based web services deployed in this domain. Also with the running server are quick launch links to open the Administrative Console, Server Logs, and the GlassFish Community Site all within Eclipse's embedded browser.

Why doesn't my cube hold a position?

- by Christian Frantz

I gave up a previous method of creating cubes so I went with a list to hold my cube objects. The list is being populated from an array like so: #region MAP float[,] map = { {0, 0, 0, 0, 0}, {0, 0, 0, 0, 0}, {0, 0, 0, 0, 0}, {0, 0, 0, 0, 0}, {0, 0, 0, 0, 0} }; #endregion MAP for (int x = 0; x < mapWidth; x++) { for (int z = 0; z < mapHeight; z++) { cubes.Add(new Cube(device, new Vector3(x, map[x,z], z), Color.Green)); } } The cube follows all the parameters of what I had before. This is just easier to deal with. But when I debug, every cube has a position of (0, 0, 0) and there's just one black cube in the middle of my screen. What could I be doing wrong here? public Vector3 cubePosition { get; set; } public Cube(GraphicsDevice graphicsDevice, Vector3 Position, Color color) { device = graphicsDevice; color = Color.Green; Position = cubePosition; SetUpIndices(); SetUpVerticesArray(); } That's the cube constructor. All variables are being passed correctly I think

Using SPServices & jQuery to Find My Stuff from Multi-Select Person/Group Field

- by Mark Rackley

Okay… quick blog post for all you SPServices fans out there. I needed to quickly write a script that would return all the tasks currently assigned to me. I also wanted it to return any task that was assigned to a group I belong to. This can actually be done with a CAML query, so no big deal, right? The rub is that the “assigned to” field is a multi-select person or group field. As far as I know (and I actually know so little) you cannot just write a CAML query to return this information. If you can, please leave a comment below and disregard the rest of this blog post… So… what’s a hacker to do? As always, I break things down to their most simple components (I really love the KISS principle and would get it tattooed on my back if people wouldn’t think it meant “Knights In Satan’s Service”. You really gotta be an old far to get that reference). Here’s what we’re going to do: Get currently logged in user’s name as it is stored in a person field Find all the SharePoint groups the current user belongs to Retrieve a set of assigned tasks from the task list and then find those that are assigned to current user or group current user belongs to Nothing too hairy… So let’s get started Some Caveats before I continue There are some obvious performance implications with this solution as I make a total of four SPServices calls and there’s a lot of looping going on. Also, the CAML query in this blog has NOT been optimized. If you move forward with this code, tweak it so that it returns a further subset of data or you will see horrible performance if you have a few hundred entries in your task list. Add a date range to the CAML or something. Find some way to limit the results as much as possible. Lastly, if you DO have a better solution, I would like you to share. Iron sharpens iron and all… Alright, let’s really get started. Get currently logged in user’s name as it is stored in a person field First thing we need to do is understand how a person group looks when you look at the XML returned from a SharePoint Web Service call. It turns out it’s stored like any other multi select item in SharePoint which is <id>;#<value> and when you assign a person to that field the <value> equals the person’s name “Mark Rackley” in my case. This is for Windows Authentication, I would expect this to be different in FBA, but I’m not using FBA. If you want to know what it looks like with FBA you can use the code in this blog and strategically place an alert to see the value. Anyway… I need to find the name of the user who is currently logged in as it is stored in the person field. This turns out to be one SPServices call: var userName = $().SPServices.SPGetCurrentUser({ fieldName: "Title", debug: false }); As you can see, the “Title” field has the information we need. I suspect (although again, I haven’t tried) that the Title field also contains the user’s name as we need it if I was using FBA. Okay… last thing we need to do is store our users name in an array for processing later: myGroups = new Array(); myGroups.push(userName); Find all the SharePoint groups the current user belongs to Now for the groups. How are groups returned in that XML stream? Same as the person <ID>;#<Group Name>, and if it’s a mutli select it’s all returned in one big long string “<ID>;#<Group Name>;#<ID>;#<Group Name>;#<ID>;#<Group Name>;#<ID>;#<Group Name>;#<ID>;#<Group Name>”. So, how do we find all the groups the current user belongs to? This is also a simple SPServices call. Using the “GetGroupCollectionFromUser” operation we can find all the groups a user belongs to. So, let’s execute this method and store all our groups. $().SPServices({ operation: "GetGroupCollectionFromUser", userLoginName: $().SPServices.SPGetCurrentUser(), async: false, completefunc: function(xData, Status) { $(xData.responseXML).find("[nodeName=Group]").each(function() { myGroups.push($(this).attr("Name")); }); } }); So, all we did in the above code was execute the “GetGroupCollectionFromUser” operation and look for the each “Group” node (row) and store the name for each group in our array that we put the user’s name in previously (myGroups). Now we have an array that contains the current user’s name as it will appear in the person field XML and all the groups the current user belongs to. The Rest Now comes the easy part for all of you familiar with SPServices. We are going to retrieve our tasks from the Task list using “GetListItems” and look at each entry to see if it belongs to this person. If it does belong to this person we are going to store it for later processing. That code looks something like this: // get list of assigned tasks that aren't closed... *modify the CAML to perform better!* $().SPServices({ operation: "GetListItems", async: false, listName: "Tasks", CAMLViewFields: "<ViewFields>" + "<FieldRef Name='AssignedTo' />" + "<FieldRef Name='Title' />" + "<FieldRef Name='StartDate' />" + "<FieldRef Name='EndDate' />" + "<FieldRef Name='Status' />" + "</ViewFields>", CAMLQuery: "<Query><Where><And><IsNotNull><FieldRef Name='AssignedTo'/></IsNotNull><Neq><FieldRef Name='Status'/><Value Type='Text'>Completed</Value></Neq></And></Where></Query>", completefunc: function (xData, Status) { var aDataSet = new Array(); //loop through each returned Task $(xData.responseXML).find("[nodeName=z:row]").each(function() { //store the multi-select string of who task is assigned to var assignedToString = $(this).attr("ows_AssignedTo"); found = false; //loop through the persons name and all the groups they belong to for(var i=0; i<myGroups.length; i++) { //if the person's name or group exists in the assigned To string //then the task is assigned to them if (assignedToString.indexOf(myGroups[i]) >= 0){ found = true; break; } } //if the Task belongs to this person then store or display it //(I'm storing it in an array) if (found){ var thisName = $(this).attr("ows_Title"); var thisStartDate = $(this).attr("ows_StartDate"); var thisEndDate = $(this).attr("ows_EndDate"); var thisStatus = $(this).attr("ows_Status"); var aDataRow=new Array( thisName, thisStartDate, thisEndDate, thisStatus); aDataSet.push(aDataRow); } }); SomeFunctionToDisplayData(aDataSet); } }); Some notes on why I did certain things and additional caveats. You will notice in my code that I’m doing an AssignedToString.indexOf(GroupName) to see if the task belongs to the person. This could possibly return bad results if you have SharePoint Group names that are named in such a way that the “IndexOf” returns a false positive. For example if you have a Group called “My Users” and a group called “My Users – SuperUsers” then if a user belonged to “My Users” it would return a false positive on executing “My Users – SuperUsers”.IndexOf(“My Users”). Make sense? Just be aware of this when naming groups, we don’t have this problem. This is where also some fine-tuning can probably be done by those smarter than me. This is a pretty inefficient method to determine if a task belongs to a user, I mean what if a user belongs to 20 groups? That’s a LOT of looping. See all the opportunities I give you guys to do something fun?? Also, why am I storing my values in an array instead of just writing them out to a Div? Well.. I want to pass my data to a jQuery library to format it all nice and pretty and an Array is a great way to do that. When all is said and done and we put all the code together it looks like: $(document).ready(function() { var userName = $().SPServices.SPGetCurrentUser({ fieldName: "Title", debug: false }); myGroups = new Array(); myGroups.push(userName ); $().SPServices({ operation: "GetGroupCollectionFromUser", userLoginName: $().SPServices.SPGetCurrentUser(), async: false, completefunc: function(xData, Status) { $(xData.responseXML).find("[nodeName=Group]").each(function() { myGroups.push($(this).attr("Name")); }); // get list of assigned tasks that aren't closed... *modify this CAML to perform better!* $().SPServices({ operation: "GetListItems", async: false, listName: "Tasks", CAMLViewFields: "<ViewFields>" + "<FieldRef Name='AssignedTo' />" + "<FieldRef Name='Title' />" + "<FieldRef Name='StartDate' />" + "<FieldRef Name='EndDate' />" + "<FieldRef Name='Status' />" + "</ViewFields>", CAMLQuery: "<Query><Where><And><IsNotNull><FieldRef Name='AssignedTo'/></IsNotNull><Neq><FieldRef Name='Status'/><Value Type='Text'>Completed</Value></Neq></And></Where></Query>", completefunc: function (xData, Status) { var aDataSet = new Array(); //loop through each returned Task $(xData.responseXML).find("[nodeName=z:row]").each(function() { //store the multi-select string of who task is assigned to var assignedToString = $(this).attr("ows_AssignedTo"); found = false; //loop through the persons name and all the groups they belong to for(var i=0; i<myGroups.length; i++) { //if the person's name or group exists in the assigned To string //then the task is assigned to them if (assignedToString.indexOf(myGroups[i]) >= 0){ found = true; break; } } //if the Task belongs to this person then store or display it //(I'm storing it in an array) if (found){ var thisName = $(this).attr("ows_Title"); var thisStartDate = $(this).attr("ows_StartDate"); var thisEndDate = $(this).attr("ows_EndDate"); var thisStatus = $(this).attr("ows_Status"); var aDataRow=new Array( thisName, thisStartDate, thisEndDate, thisStatus); aDataSet.push(aDataRow); } }); SomeFunctionToDisplayData(aDataSet); } }); } }); }); Final Thoughts So, there you have it. Take it and run with it. Make it something cool (and tell me how you did it). Another possible way to improve performance in this scenario is to use a DVWP to display the tasks and use jQuery and the “myGroups” array from this blog post to hide all those rows that don’t belong to the current user. I haven’t tried it, but it does move some of the processing off to the server (generating the view) so it may perform better. As always, thanks for stopping by… hope you have a Merry Christmas…

How ReSharper saved the day

- by Randy Walker

The Back Story: As a Microsoft MVP awardee, one of the many benefits is free software, books, and various products. Some of the producers/manufacturers ask for reviews in exchange, others just ask for a brief mention (nothing is ever really free). But considering that some of the products are essential to my everyday computing, I never mind mentioning their names and evangelizing their products. One of these tools just happened to save me a countless number of hours. With the release of Microsoft’s Visual Studio 2010, JetBrains released their new 5.0 version of ReSharper. The Story: My specialty is Visual Basic development. I am not, and probably will never be a C# developer. As such, trying to figure out how to debug a C# project, that was written 2 years ago by a contract developer, let’s just say it’s a painful process. I have a special class for config file reading and writing, written in C#. I kept getting exceptions when the reader would get to a line that had an xml comment in it. It took me a couple of hours to narrow down where it was happening and why, but I couldn’t figure out the best way to fix it. It was a for loop that was implicitly casting the type of the variable. I knew I need to explicitly cast the variable type, but only after the type was verified. So after I finally got some of the code written, ReSharper gave me some suggestions on how to write the code better. One of the ways was to safely cast the variable into the type I wanted. Blammo, no more exceptions in a way I hadn’t anticipated. Instead of having to check the type before I cast it. Beautiful, simple, and taught me a better way to code C#. Kudos JetBrains … now if it only worked better with VB (then it could be called ReBasic, ReVB, RE???)

As you may have heard, Oracle Database 12c is now available for Oracle Solaris and Oracle Linux. Among other things, that means we now have the opportunity to share some of the cool things the Oracle Database and Oracle Solaris engineering teams have been doing together. And here's a good one: In this screencast, Jon Haslam describes how on Oracle Solaris 11, DTrace is now integrated into Oracle Database V$ views to provide a top-to-bottom picture of a database transaction I/O -- from storage devices, through the Oracle Solaris kernel, up to Oracle Database 12c itself: With this end-to-end view, you can easily identify I/O outliers -- transactions that are taking an unusually long time to complete -- and use this comprehensive data to identify and mitigate storage system problems that were previously extremely hard to debug. This is a great example of the power of DTrace, which is just about to celebrate its 10th anniversary in the wild. The screencast has some nice examples of DTrace's power on its own, as well as diving into the DTrace/Oracle Database 12c synergy. There's more, of course. Over on the OTN Garage blog, Rick Ramsey has put together a nice compendium of ways the OS makes the database scream, and Ginny Henningsen's written an article on the same topic. And, we've also got an OTN page that digs further into Oracle Database / Oracle Solaris synergies.

Php profiling on production server or other options

- by absentx

Alright I need some help here. I am commonly asked to speed up certain sections of some websites that I program for. I have yet to be able to figure out how to use a good php diagnosis/profiling tool. Some things to consider: The sites I am working on are already built, getting a testing server set up locally is just a huge pain..I have to rewrite include paths and just so many things. This is a results oriented deal and spending days to get a site fully working on a testing platform so I can debug one page probably isn't an option. I can write tons of php, but I have no clue how to interact or mess with servers. So every tutorial I read about setting up xdebug or xhprof all seem to involve getting something installed on a production server that I don't have access to or have no clue how to work with. So are there any solutions out there that will show me where my php is slow without having to do all sorts of server stuff that I just don't know how to do? Xhprof seems to be the closest to useable for me but from what I can tell it still has to be installed on a server. If anyone can just point me in the right direction on this I would be very grateful. Maybe getting these things put on the server isn't a big deal...but I have never interacted with server command lines or anything like that. I suppose I should start sometime but I really have no idea where to start. Plus I realize that profiling on a live platform is not the greatest idea either but I feel I am in a tough spot. I have speed issues to solve and setting up a local environment while a great idea, just doesn't seem real practical at the moment.

Farseer tutorial for the absolute beginners

- by Bil Simser

This post is inspired (and somewhat a direct copy) of a couple of posts Emanuele Feronato wrote back in 2009 about Box2D (his tutorial was ActionScript 3 based for Box2D, this is C# XNA for the Farseer Physics Engine). Here’s what we’re building: What is Farseer The Farseer Physics Engine is a collision detection system with realistic physics responses to help you easily create simple hobby games or complex simulation systems. Farseer was built as a .NET version of Box2D (based on the Box2D.XNA port of Box2D). While the constructs and syntax has changed over the years, the principles remain the same. This tutorial will walk you through exactly what Emanuele create for Flash but we’ll be doing it using C#, XNA and the Windows Phone platform. The first step is to download the library from its home on CodePlex. If you have NuGet installed, you can install the library itself using the NuGet package that but we’ll also be using some code from the Samples source that can only be obtained by downloading the library. Once you download and unpacked the zip file into a folder and open the solution, this is what you will get: The Samples XNA WP7 project (and content) have all the demos for Farseer. There’s a wealth of info here and great examples to look at to learn. The Farseer Physics XNA WP7 project contains the core libraries that do all the work. DebugView XNA contains an XNA-ready class to let you view debug data and information in the game draw loop (which you can copy into your project or build the source and reference the assembly). The downloaded version has to be compiled as it’s only available in source format so you can do that now if you want (open the solution file and rebuild everything). If you’re using the NuGet package you can just install that. We only need the core library and we’ll be copying in some code from the samples later. Your first Farseer experiment Start Visual Studio and create a new project using the Windows Phone template can call it whatever you want. It’s time to edit Game1.cs 1 public class Game1 : Game 2 { 3 private readonly GraphicsDeviceManager _graphics; 4 private DebugViewXNA _debugView; 5 private Body _floor; 6 private SpriteBatch _spriteBatch; 7 private float _timer; 8 private World _world; 9 10 public Game1() 11 { 12 _graphics = new GraphicsDeviceManager(this) 13 { 14 PreferredBackBufferHeight = 800, 15 PreferredBackBufferWidth = 480, 16 IsFullScreen = true 17 }; 18 19 Content.RootDirectory = "Content"; 20 21 // Frame rate is 30 fps by default for Windows Phone. 22 TargetElapsedTime = TimeSpan.FromTicks(333333); 23 24 // Extend battery life under lock. 25 InactiveSleepTime = TimeSpan.FromSeconds(1); 26 } 27 28 protected override void LoadContent() 29 { 30 // Create a new SpriteBatch, which can be used to draw textures. 31 _spriteBatch = new SpriteBatch(_graphics.GraphicsDevice); 32 33 // Load our font (DebugViewXNA needs it for the DebugPanel) 34 Content.Load<SpriteFont>("font"); 35 36 // Create our World with a gravity of 10 vertical units 37 if (_world == null) 38 { 39 _world = new World(Vector2.UnitY*10); 40 } 41 else 42 { 43 _world.Clear(); 44 } 45 46 if (_debugView == null) 47 { 48 _debugView = new DebugViewXNA(_world); 49 50 // default is shape, controller, joints 51 // we just want shapes to display 52 _debugView.RemoveFlags(DebugViewFlags.Controllers); 53 _debugView.RemoveFlags(DebugViewFlags.Joint); 54 55 _debugView.LoadContent(GraphicsDevice, Content); 56 } 57 58 // Create and position our floor 59 _floor = BodyFactory.CreateRectangle( 60 _world, 61 ConvertUnits.ToSimUnits(480), 62 ConvertUnits.ToSimUnits(50), 63 10f); 64 _floor.Position = ConvertUnits.ToSimUnits(240, 775); 65 _floor.IsStatic = true; 66 _floor.Restitution = 0.2f; 67 _floor.Friction = 0.2f; 68 } 69 70 protected override void Update(GameTime gameTime) 71 { 72 // Allows the game to exit 73 if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) 74 Exit(); 75 76 // Create a random box every second 77 _timer += (float) gameTime.ElapsedGameTime.TotalSeconds; 78 if (_timer >= 1.0f) 79 { 80 // Reset our timer 81 _timer = 0f; 82 83 // Determine a random size for each box 84 var random = new Random(); 85 var width = random.Next(20, 100); 86 var height = random.Next(20, 100); 87 88 // Create it and store the size in the user data 89 var box = BodyFactory.CreateRectangle( 90 _world, 91 ConvertUnits.ToSimUnits(width), 92 ConvertUnits.ToSimUnits(height), 93 10f, 94 new Point(width, height)); 95 96 box.BodyType = BodyType.Dynamic; 97 box.Restitution = 0.2f; 98 box.Friction = 0.2f; 99 100 // Randomly pick a location along the top to drop it from 101 box.Position = ConvertUnits.ToSimUnits(random.Next(50, 400), 0); 102 } 103 104 // Advance all the elements in the world 105 _world.Step(Math.Min((float) gameTime.ElapsedGameTime.TotalMilliseconds*0.001f, (1f/30f))); 106 107 // Clean up any boxes that have fallen offscreen 108 foreach (var box in from box in _world.BodyList 109 let pos = ConvertUnits.ToDisplayUnits(box.Position) 110 where pos.Y > _graphics.GraphicsDevice.Viewport.Height 111 select box) 112 { 113 _world.RemoveBody(box); 114 } 115 116 base.Update(gameTime); 117 } 118 119 protected override void Draw(GameTime gameTime) 120 { 121 GraphicsDevice.Clear(Color.FromNonPremultiplied(51, 51, 51, 255)); 122 123 _spriteBatch.Begin(); 124 125 var projection = Matrix.CreateOrthographicOffCenter( 126 0f, 127 ConvertUnits.ToSimUnits(_graphics.GraphicsDevice.Viewport.Width), 128 ConvertUnits.ToSimUnits(_graphics.GraphicsDevice.Viewport.Height), 0f, 0f, 129 1f); 130 _debugView.RenderDebugData(ref projection); 131 132 _spriteBatch.End(); 133 134 base.Draw(gameTime); 135 } 136 } 137 Lines 4: Declare the debug view we’ll use for rendering (more on that later). Lines 8: Declare _world variable of type class World. World is the main object to interact with the Farseer engine. It stores all the joints and bodies, and is responsible for stepping through the simulation. Lines 12-17: Create the graphics device we’ll be rendering on. This is an XNA component and we’re just setting it to be the same size as the phone and toggling it to be full screen (no system tray). Lines 34: We create a SpriteFont here by adding it to the project. It’s called “font” because that’s what the DebugView uses but you can name it whatever you want (and if you’re not using DebugView for your production app you might have several fonts). Lines 37-44: We create the physics environment that Farseer uses to contain all the objects by specifying it here. We’re using Vector2.UnitY*10 to represent the gravity to be used in the environment. In other words, 10 units going in a downward motion. Lines 46-56: We create the DebugViewXNA here. This is copied from the […] from the code you downloaded and provides the ability to render all entities onto the screen. In a production release you’ll be doing the rendering yourself of each object but we cheat a bit for the demo and let the DebugView do it for us. The other thing it can provide is to render out a panel of debugging information while the simulation is going on. This is useful in tracking down objects, figuring out how something works, or just keeping track of what’s in the engine. Lines 49-67: Here we create a rigid body (Farseer only supports rigid bodies) to represent the floor that we’ll drop objects onto. We create it by using one of the Farseer factories and specifying the width and height. The ConvertUnits class is copied from the samples code as-is and lets us toggle between display units (pixels) and simulation units (usually metres). We’re creating a floor that’s 480 pixels wide and 50 pixels high (converting them to SimUnits for the engine to understand). We also position it near the bottom of the screen. Values are in metres and when specifying values they refer to the centre of the body object. Lines 77-78: The game Update method fires 30 times a second, too fast to be creating objects this quickly. So we use a variable to track the elapsed seconds since the last update, accumulate that value, then create a new box to drop when 1 second has passed. Lines 89-94: We create a box the same way we created our floor (coming up with a random width and height for the box). Lines 96-101: We set the box to be Dynamic (rather than Static like the floor object) and position it somewhere along the top of the screen. And now you created the world. Gravity does the rest and the boxes fall to the ground. Here’s the result: Farseer Physics Engine Demo using XNA Lines 105: We must update the world at every frame. We do this with the Step method which takes in the time interval. [more] Lines 108-114: Body objects are added to the world but never automatically removed (because Farseer doesn’t know about the display world, it has no idea if an item is on the screen or not). Here we just loop through all the entities and anything that’s dropped off the screen (below the bottom) gets removed from the World. This keeps our entity count down (the simulation never has more than 30 or 40 objects in the world no matter how long you run it for). Too many entities and the app will grind to a halt. Lines 125-130: Farseer knows nothing about the UI so that’s entirely up to you as to how to draw things. Farseer is just tracking the objects and moving them around using the physics engine and it’s rules. You’ll still use XNA to draw items (using the SpriteBatch.Draw method) so you can load up your usual textures and draw items and pirates and dancing zombies all over the screen. Instead in this demo we’re going to cheat a little. In the sample code for Farseer you can download there’s a project called DebugView XNA. This project contains the DebugViewXNA class which just handles iterating through all the bodies in the world and drawing the shapes. So we call the RenderDebugData method here of that class to draw everything correctly. In the case of this demo, we just want to draw Shapes so take a look at the source code for the DebugViewXNA class as to how it extracts all the vertices for the shapes created (in this case simple boxes) and draws them. You’ll learn a *lot* about how Farseer works just by looking at this class. That’s it, that’s all. Simple huh? Hope you enjoy the code and library. Physics is hard and requires some math skills to really grok. The Farseer Physics Engine makes it pretty easy to get up and running and start building games. In future posts we’ll get more in-depth with things you can do with the engine so this is just the beginning. Enjoy!

nautilus crash when merging/overwriting files

- by sBlatt

On my Ubuntu 10.10, whenever I want to copy some files/folders over some other files/folders, or when I try to empty the trash, nautilus crashes! Example: I have a folder with some files. Now I want to overwrite this folder with a folder with the same name, same files, but some additional files, the merge window comes up, I choose merge and nautilus crashes (does not respond, when I press the close button I can force close it). Some times it even does the copying/emptying (trash), but it always crashes! This happens when copying to the same partition/ntfs partition/netshares, but not when I make a new folder and copy the files/folders into that (without overwriting anything). On a netshare, it's even possible to merge these files afterwards with another computer! dmesg/syslog/messages does not show any entry related to that problem. Does anyone have a solution for this very annoying problem? EDIT: dpkg -l nautilus* (see output in pastebin) EDIT2: I found out, nautilus already crashes before clicking replace/merge (as soon as the question appeares. In the video it's not entirely clear, that i click the cross before the force-close dialog appeares. Video of problem nautilus-debug-log.txt EDIT3: Filed bugreport: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/678233

C++ Iterator lifetime and detecting invalidation

- by DK.

Based on what's considered idiomatic in C++11: should an iterator into a custom container survive the container itself being destroyed? should it be possible to detect when an iterator becomes invalidated? are the above conditional on "debug builds" in practice? Details: I've recently been brushing up on my C++ and learning my way around C++11. As part of that, I've been writing an idiomatic wrapper around the uriparser library. Part of this is wrapping the linked list representation of parsed path components. I'm looking for advice on what's idiomatic for containers. One thing that worries me, coming most recently from garbage-collected languages, is ensuring that random objects don't just go disappearing on users if they make a mistake regarding lifetimes. To account for this, both the PathList container and its iterators keep a shared_ptr to the actual internal state object. This ensures that as long as anything pointing into that data exists, so does the data. However, looking at the STL (and lots of searching), it doesn't look like C++ containers guarantee this. I have this horrible suspicion that the expectation is to just let containers be destroyed, invalidating any iterators along with it. std::vector certainly seems to let iterators get invalidated and still (incorrectly) function. What I want to know is: what is expected from "good"/idiomatic C++11 code? Given the shiny new smart pointers, it seems kind of strange that STL allows you to easily blow your legs off by accidentally leaking an iterator. Is using shared_ptr to the backing data an unnecessary inefficiency, a good idea for debugging or something expected that STL just doesn't do? (I'm hoping that grounding this to "idiomatic C++11" avoids charges of subjectivity...)

HTC Android device mounted as USB drive is read-only unless I'm root

- by Ian Dickinson

When I connect my HTC Incredible S to my Ubuntu 10.10 system as a USB drive, the device seems to mount OK, but is read-only unless I access it as root. For example, if I run nautilus, I can't drag and drop files to the SD-card in the phone, but if I run sudo nautilus I can. I have USB debug support set on the phone (Applications > Development > USB debugging) and I have added a rule for the device in /etc/udev/rules.d/51-android.rules on my Ubuntu system. Any suggestions as to how I can mount the drive so that I can copy content to the SD card without needing to sudo? Update Following advice from waltinator, I added the following line to my /etc/fstab: UUID=3537-3834 /media/usb1 vfat rw,user,noexec,nodev,nosuid,noauto However, the Android device is still being auto-mounted on /media/usb1 with uid and gid root. Update 2 syslog output: Nov 21 23:38:40 rowan-15 usbmount[4352]: executing command: mount -tvfat -osync,noexec,nodev,noatime,nodiratime /dev/sdd1 /media/usb1 Nov 21 23:38:40 rowan-15 usbmount[4352]: executing command: run-parts /etc/usbmount/mount.d

Why does 301 redirect work for http but not for https?

- by Tom G

Through my domain registrar I have set up a domain, essayme.co.uk, to automatically forward to https://google.com. If I go to http://essayme.co.uk it works as expected and redirects me to https://google.com. $curl -i http://essayme.co.uk HTTP/1.1 301 Moved Permanently Cache-Control: max-age=900 Content-Type: text/html Location: https://google.com Server: Microsoft-IIS/7.5 X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Sat, 07 Jun 2014 11:14:16 GMT Content-Length: 0 Age: 0 Connection: keep-alive However, if I go to https://essayme.co.uk it just freezes and times out. $curl -i https://essayme.co.uk curl: (7) Failed connect to essayme.co.uk:443; Operation timed out What is happening in the second case? (and, if possible, how can I get the redirect to work for https?) Problem background/clarification: I don't have an SSL certificate for the essayme.co.uk domain above, but I do for my live domain (let's call it mywebsite.com), and I was seeing the exact same problem on this domain (hence why I'm trying to debug the problem). Unfortunately I can't experiment with the live domain (as it's live) and I would like to avoid having to buy a second certificate for essayme.co.uk just for debugging (unless absolutely necessary). The problem I was seeing: my live domain, mywebsite.com (not its real name), has a valid SSL certificate. Visiting https://www.mywebsite.com displayed the webpage as expected. I had set up forwarding (like in the question above) from the naked domain (mywebsite.com) to https://www.mywebsite.com) Visiting http://mywebsite.com redirected to https://www.mywebsite.com as expected. However, visiting https://mywebsite.com would freeze and time out (as in the question above). I also tried forwarding it to http://www.otherwebsite.com as an experiment (i.e. forwarding to another site that does not use SSL), but the result was the same: Visiting http://mywebsite.com redirected to http://www.otherwebsite.com as expected. Visiting https://mywebsite.com would freeze and time out again. So I set up essayme.co.uk as an experiment to try and understand why it doesn't work.

For a Javascript library, what is the best or standard way to support extensibility

- by Michael Best

Specifically, I want to support "plugins" that modify the behavior of parts of the library. I couldn't find much information on the web about this subject. But here are my ideas for how a library could be extensible. The library exports an object with both public and "protected" functions. A plugin can replace any of those functions, thus modifying the library's behavior. Advantages of this method are that it's simple and that the plugin's functions can have full access to the library's "protected" functions. Disadvantages are that the library may be harder to maintain with a larger set of exposed functions and it could be hard to debug if multiple plugins are involved (how to know which plugin modified which function?). The library provides an "add plugin" function that accepts an object with a specific interface. Internally, the library will use the plugin instead of it's own code if appropriate. With this method, the internals of the library can be rearranged more freely as long as it still supports the same plugin interface. This could also support having different plugin interfaces to modify different parts of the library. A disadvantage of this method is that the plugins may have to re-implement code that is already part of the library since the library's internal functions are not exported. The library provides a "set implementation" function that accepts an object inherited from a specific base object. The library's public API calls functions in the implementation object for any functionality that can be modified and the base implementation object includes the core functionality, with both external (to the API) and internal functions. A plugin creates a new implementation object, which inherits from the base object and replaces any functions it wants to modify. This combines advantages and disadvantages of both the other methods.

Bundling in visual studio 2012 for web optimization

- by Jalpesh P. Vadgama

I have been writing a series of posts about Visual Studio 2012 features. This series describes what are the new features in the Visual Studio 2012. This post will also be part of Visual Studio 2012 feature series. As we know now days web applications or site are providing more and more features and due to that we have include lots of JavaScript and CSS files in our web application.So once we load site then we will have all the JavaScript js files and CSS files loaded in the browsers and If you have lots of JavaScript files then its consumes lots of time when browser request them. Following images show the same situation over there. Here you can see total 25 files loaded into the system and it's almost more than 1MB of total size. As we need to have our web application of site very responsive and need to have high performance application/site, this will be a performance bottleneck to our site. In situation like this, the bundling feature of Visual Studio 2012 and ASP.NET 4.5 comes very handy. With the help of this feature we do optimization there and we can increase performance of our application. To enable this feature in Visual Studio 2012 we just made debug=”false” in web.config of our application like following. Now once you enable this feature and run this application in the browser to see your traffic it will have less items like following. As you can see in the above image there are only 8 items. So after enabling bundling it will automatically convert all js and css files into the one request. Isn’t that cool feature? This feature will surely going to have great impact on performance. Hope you like it. Stay tuned for more.. Till then happy programming!!

Texture2D.GetData fails to return pixel colour data

- by Chris Charabaruk

Because I'm using sprite sheets instead of an individual texture per sprite, I need to pass in a Rectangle when calling Texture2D.GetData() in my collision detection for per-pixel tests. Unfortunately, without fail I get an ArgumentException percolated down from an internal method inside the Texture (not Texture2D) class. My code for getting the texture data looks like this: public override Color[] GetPixelData() { Color[] data = new Color[(int)size.Product()]; Rectangle rect = new Rectangle(hframe * (int)size.X, vframe * (int)size.Y, (int)size.X, (int)size.Y); #if DEBUG if (sprite.Bounds.Contains(rect) && sprite.Format == SurfaceFormat.Color) #endif sprite.GetData(0, rect, data, 0, 1); return data; } Even with the check to ensure I'm grabbing a valid rectangle and that the texture format matches what I'm trying to get, I still get that exception, claiming "The size of the data passed in is too large or too small for this resource." Unfortunately, the debugger won't let me check the locals within the Texture.ValidateTotalSize() method where the exception originates. Has anyone else had this problem and knows how to fix it? I'm relying on AABB testing only for now, but that doesn't really work for some of my game's entities due to odd shapes, rotation and scaling.

Video game "Gish" will only launch from command line

- by aberration

Platform: Lubuntu 11.10 x64 Program: Gish When I try to launch Gish from the command line (/opt/gish/gi.sh), there are no problems. But when I try to launch it from the LXDE menu, it will not start. Contents of /usr/share/applications/gish.desktop: [Desktop Entry] Categories=Game;ActionGame;AdventureGame;ArcadeGame; Exec=/opt/gish/gi.sh Path=/opt/gish Icon=x-gish Terminal=false Type=Application Name=Gish I tried changing Terminal=false to Terminal=true to debug it, but then I just got a blank terminal, and the game didn't start. Edit: Here is some additional information, as requested by Eliah Kagan below: I tried editing /usr/share/applications/gish.desktop, as recommended, but it had no effect However, ~/.xsession-errors contained the following error: [: 8: x86_64: unexpected operator ./gish_32: error while loading shared libraries: libGL.so.1: wrong ELF class: ELFCLASS64 I think there's a problem with the /opt/gish/gi.sh shell script. This is its contents: cd /opt/gish/ MACHINE_TYPE=`uname -m` if [ ${MACHINE_TYPE} == 'x86_64' ]; then ./gish_64 else ./gish_32 fi I'm not too familiar with Bash, so hopefully someone else can point out the error. I have a 64-bit machine. I think that when the script is run from the command line, it's properly launching the 64-bit version (/opt/gish/gish_64), but when it's run from the LXDE menu, it's launching the 32-bit version (/opt/gish/gish_32), which is causing the libGL.so.1 error. However, this may be related to my libGL.so.1 problems with 2 other games.

Composing programs from small simple pieces: OOP vs Functional Programming

- by Jay Godse

I started programming when imperative programming languages such as C were virtually the only game in town for paid gigs. I'm not a computer scientist by training so I was only exposed to Assembler and Pascal in school, and not Lisp or Prolog. Over the 1990s, Object-Oriented Programming (OOP) became more popular because one of the marketing memes for OOP was that complex programs could be composed of loosely coupled but well-defined, well-tested, cohesive, and reusable classes and objects. And in many cases that is quite true. Once I learned object-oriented programming my C programs became better because I structured them more like classes and objects. In the last few years (2008-2014) I have programmed in Ruby, an OOP language. However, Ruby has many functional programming (FP) features such as lambdas and procs, which enable a different style of programming using recursion, currying, lazy evaluation and the like. (Through ignorance I am at a loss to explain why these techniques are so great). Very recently, I have written code to use methods from the Ruby Enumerable library, such as map(), reduce(), and select(). Apparently this is a functional style of programming. I have found that using these methods significantly reduce code volume, and make my code easier to debug. Upon reading more about FP, one of the marketing claims made by advocates is that FP enables developers to compose programs out of small well-defined, well-tested, and reusable functions, which leads to less buggy code, and low code volume. QUESTIONS: Is the composition of complex program by using FP techniques contradictory to or complementary to composition of a complex program by using OOP techniques? In which situations is OOP more effective, and when is FP more effective? Is it possible to use both techniques in the same complex program? Do the techniques overlap or contradict each other?
