• How to prevent screen locking when lid is closed?

  - by Joe Casadonte

  I have Ubuntu 11.10 with Gnome 3 (no Unity), gnome-screen-saver has been removed and replaced with xscreensaver. The screensaver stuff all works fine -- no complaints there. When I close my laptop lid, even for a second, the screen locks (and the dialog box asking for my password is xscreensaver's). I'd like for this not to happen... Things I've tried/looked at already: xscreensaver settings - the "Lock Screen After" checkbox is not checked (though I've also tried it checked and set to 720 minutes) gconf-editor - apps -> gnome-screensaver -> lock_enabled is not checked System Settings - Power - "When the lid is closed" is set to "Do nothing" for both battery and A/C System Settings - Screen - Lock is "off" gconf-editor - apps -> gnome-power-manager -> buttons -> lid_ac && lid_battery are both set to "nothing" dconf-editor - apps -> org -> gnome -> desktop -> screensaver -> lock_enabled is not checked Output from: gsettings list-recursively org.gnome.settings-daemon.plugins.power: org.gnome.settings-daemon.plugins.power active true org.gnome.settings-daemon.plugins.power button-hibernate 'hibernate' org.gnome.settings-daemon.plugins.power button-power 'suspend' org.gnome.settings-daemon.plugins.power button-sleep 'suspend' org.gnome.settings-daemon.plugins.power button-suspend 'suspend' org.gnome.settings-daemon.plugins.power critical-battery-action 'hibernate' org.gnome.settings-daemon.plugins.power idle-brightness 30 org.gnome.settings-daemon.plugins.power idle-dim-ac false org.gnome.settings-daemon.plugins.power idle-dim-battery true org.gnome.settings-daemon.plugins.power idle-dim-time 10 org.gnome.settings-daemon.plugins.power lid-close-ac-action 'nothing' org.gnome.settings-daemon.plugins.power lid-close-battery-action 'nothing' org.gnome.settings-daemon.plugins.power notify-perhaps-recall true org.gnome.settings-daemon.plugins.power percentage-action 2 org.gnome.settings-daemon.plugins.power percentage-critical 3 org.gnome.settings-daemon.plugins.power percentage-low 10 org.gnome.settings-daemon.plugins.power priority 1 org.gnome.settings-daemon.plugins.power sleep-display-ac 600 org.gnome.settings-daemon.plugins.power sleep-display-battery 600 org.gnome.settings-daemon.plugins.power sleep-inactive-ac false org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 0 org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'suspend' org.gnome.settings-daemon.plugins.power sleep-inactive-battery true org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout 0 org.gnome.settings-daemon.plugins.power sleep-inactive-battery-type 'suspend' org.gnome.settings-daemon.plugins.power time-action 120 org.gnome.settings-daemon.plugins.power time-critical 300 org.gnome.settings-daemon.plugins.power time-low 1200 org.gnome.settings-daemon.plugins.power use-time-for-policy true gnome-settings-daemon is running: <~> $ ps -ef | grep gnome-settings-daemon 1000 1719 1645 0 19:37 ? 00:00:01 /usr/lib/gnome-settings-daemon/gnome-settings-daemon 1000 1726 1 0 19:37 ? 00:00:00 /usr/lib/gnome-settings-daemon/gsd-printer 1000 1774 1645 0 19:37 ? 00:00:00 /usr/lib/gnome-settings-daemon/gnome-fallback-mount-helper Anything else I can check?

• How to update all the SSIS packages&rsquo; Connection Managers in a BIDS project with PowerShell

  - by Luca Zavarella

  During the development of a BI solution, we all know that 80% of the time is spent during the ETL (Extract, Transform, Load) phase. If you use the BI Stack Tool provided by Microsoft SQL Server, this step is accomplished by the development of n Integration Services (SSIS) packages. In general, the number of packages made ??in the ETL phase for a non-trivial solution of BI is quite significant. An SSIS package, therefore, extracts data from a source, it "hammers" :) the data and then transfers it to a specific destination. Very often it happens that the connection to the source data is the same for all packages. Using Integration Services, this results in having the same Connection Manager (perhaps with the same name) for all packages: The source data of my BI solution comes from an Helper database (HLP), then, for each package tha import this data, I have the HLP Connection Manager (the use of a Shared Data Source is not recommended, because the Connection String is wired and therefore you have to open the SSIS project and use the proper wizard change it...). In order to change the HLP Connection String at runtime, we could use the Package Configuration, or we could run our packages with DTLoggedExec by Davide Mauri (a must-have if you are developing with SQL Server 2005/2008). But my need was to change all the HLP connections in all packages within the SSIS Visual Studio project, because I had to version them through Team Foundation Server (TFS). A good scribe with a lot of patience should have changed by hand all the connections by double-clicking the HLP Connection Manager of each package, and then changing the referenced server/database: Not being endowed with such virtues :) I took just a little of time to write a small script in PowerShell, using the fact that a SSIS package (a .dtsx file) is nothing but an xml file, and therefore can be changed quite easily. I'm not a guru of PowerShell, but I managed more or less to put together the following lines of code: $LeftDelimiterString = "Initial Catalog=" $RightDelimiterString = ";Provider=" $ToBeReplacedString = "AstarteToBeReplaced" $ReplacingString = "AstarteReplacing" $MainFolder = "C:\MySSISPackagesFolder" $files = get-childitem "$MainFolder" *.dtsx `       | Where-Object {!($_.PSIsContainer)} foreach ($file in $files) {       (Get-Content $file.FullName) `             | % {$_ -replace "($LeftDelimiterString)($ToBeReplacedString)($RightDelimiterString)", "`$1$ReplacingString`$3"} ` | Set-Content $file.FullName; } The script above just opens any SSIS package (.dtsx) in the supplied folder, then for each of them goes in search of the following text: Initial Catalog=AstarteToBeReplaced;Provider= and it replaces the text found with this: Initial Catalog=AstarteReplacing;Provider= I don’t enter into the details of each cmdlet used. I leave the reader to search for these details. Alternatively, you can use a specific object model exposed in some .NET assemblies provided by Integration Services, or you can use the Pacman utility: Enjoy! :) P.S. Using TFS as versioning system, before running the script I checked out the packages and, after the script executed succesfully, I checked in them.

• cocos2dx - Custom Fragment Shader and CCRenderTexture

  - by saiy2k

  I have a CCRenderTexture that is filled with a sprite when the scene is loaded, as follows, canvas = CCRenderTexture::create(this->getContentSize().width, this->getContentSize().height); canvas->setPosition(data->position); canvas->beginWithClear(0.0, 0.0, 0.0, 0); this->visit(); canvas->end(); The above code is written within a class, which derives from CCSprite (Hence this). Then, in another function applyShader(), I create a sprite named splat, from the texture of CCRenderTexture *canvas. Thus splat will contain the whole texture of canvas. Now I apply a custom fragment shader to the splat by calling the function splat->renderShader(), which will modify some small portion of the whole texture. Then I draw the modified texture back to the CCRenderTexture *canvas. Hence, applyShader() will * take a texture from CCRenderTexture, * create a sprite based on it, * apply a fragment shader to it * and draw the modified texture back to CCRenderTexture. This applyShader() will be called repetitively and its code is as follows: splat = Splat::createWithTexture(art->canvas->getSprite()->getTexture()); splat->renderShader(); art->canvas->begin(); splat->visit(); art->canvas->end(); My shader code is (nothing fancy) precision mediump float; varying vec2 v_texCoord; uniform sampler2D u_texture; uniform sampler2D u_colorRampTexture; uniform float params[5]; void main() { gl_FragColor = texture2D(u_texture, v_texCoord); return; } So, with the above code I expect the original sprite this to get rendered over and over again without any visual changes. But on each call to applyShader(), the texture is getting stretched a little and the stretched image is getting rendered. After some 10 calls, the image gets so distorted. Can someone please tell me where I am going wrong? Thanks :-) PS: All code shown here is partial, not complete code. Edit: Adding Screens Update: The problem has nothing to do with shaders it seems. It happens even when I dont call renderShader(). The actual lines of code is: splat = Splat::createWithTexture(art->canvas->getSprite()->getTexture()); splat->setPosition( ccp( art->getContentSize().width * 0.5, art->getContentSize().height * 0.5 ) ); splat->setFlipY(true); art->canvas->begin(); splat->visit(); art->canvas->end();

• ASP.NET Asynchronous Pages and when to use them

  - by rajbk

  There have been several articles posted about using  asynchronous pages in ASP.NET but none of them go into detail as to when you should use them. I finally found a great post by Thomas Marquardt that explains the process in depth. He addresses a key misconception also: So, in your ASP.NET application, when should you perform work asynchronously instead of synchronously? Well, only 1 thread per CPU can execute at a time.  Did you catch that?  A lot of people seem to miss this point...only one thread executes at a time on a CPU. When you have more than this, you pay an expensive penalty--a context switch. However, if a thread is blocked waiting on work...then it makes sense to switch to another thread, one that can execute now.  It also makes sense to switch threads if you want work to be done in parallel as opposed to in series, but up until a certain point it actually makes much more sense to execute work in series, again, because of the expensive context switch. Pop quiz: If you have a thread that is doing a lot of computational work and using the CPU heavily, and this takes a while, should you switch to another thread? No! The current thread is efficiently using the CPU, so switching will only incur the cost of a context switch. Ok, well, what if you have a thread that makes an HTTP or SOAP request to another server and takes a long time, should you switch threads? Yes! You can perform the HTTP or SOAP request asynchronously, so that once the "send" has occurred, you can unwind the current thread and not use any threads until there is an I/O completion for the "receive". Between the "send" and the "receive", the remote server is busy, so locally you don't need to be blocking on a thread, but instead make use of the asynchronous APIs provided in .NET Framework so that you can unwind and be notified upon completion. Again, it only makes sense to switch threads if the benefit from doing so out weights the cost of the switch. Read more about it in these posts: Performing Asynchronous Work, or Tasks, in ASP.NET Applications http://blogs.msdn.com/tmarq/archive/2010/04/14/performing-asynchronous-work-or-tasks-in-asp-net-applications.aspx ASP.NET Thread Usage on IIS 7.0 and 6.0 http://blogs.msdn.com/tmarq/archive/2007/07/21/asp-net-thread-usage-on-iis-7-0-and-6-0.aspx   PS: I generally do not write posts that simply link to other posts but think it is warranted in this case.

• UV texture mapping with perspective correct interpolation

  - by Twodordan

  I am working on a software rasterizer for educational purposes and I am having issues with the texturing. The problem is, only one face of the cube gets correctly textured. The rest are stretched edges: You can see the running program online here. I have used cartesian coordinates, and all I do is interpolate the uv values along the scanlines. The general formula I use for interpolating the uv coordinates is pretty much the one I use for the z-buffering interpolation and looks like this (in this case for horizontal scanlines): u_Slope = (right.u - left.u) / (triangleRight_x - triangleLeft_x); v_Slope = (right.v - left.v) / (triangleRight_x - triangleLeft_x); //[...] new_u = left.u + ((currentX_onScanLine - triangleLeft_x) * u_Slope); new_v = left.v + ((currentX_onScanLine - triangleLeft_x) * v_Slope); Then, when I add each point to the pixel buffer, I restore z and uv: z = (1/z); uv.u = Math.round(uv.u * z *100);//*100 because my texture is 100x100px uv.v = Math.round(uv.v * z *100); Then I turn the u v indexes into one index in order to fetch the correct pixel from the image data (which is a 1 dimensional px array): var index = texture.width * uv.u + uv.v; //and the rest is unimportant imagedata[index].RGBA bla bla The interpolation formula is correct considering the consistency of the texture (including the straight stripes). However, I seem to get quite a lot of 0 values for either u or v. Which is probably why I only get one face right. Furthermore, why is the texture flipped horizontally? (the "1" is flipped) I must get some sleep now, but before I get into further dissecting of every single value to see what goes wrong, Can someone more experienced guess why might this be happening, just by looking at the cube? "I have no idea what I'm doing" (it's my first time implementing a rasterizer). Did I miss an important stage? Thanks for any insight. PS: My UV values are as follows: { u:0, v:0 }, { u:0, v:0.5 }, { u:0.5, v:0.5 }, { u:0.5, v:0 }, { u:0, v:0 }, { u:0, v:0.5 }, { u:0.5, v:0.5 }, { u:0.5, v:0 }

• My VS 2010 and ASP.NET 4 Talks Online

  - by ScottGu

  The past 7 years I’ve done an annual all day event in Arizona – organized by the most excellent Scott Cate (who always does a phenomenal job organizing the event and making it a great one). Earlier this month I visited and presented 4+ hours of content covering VS 2010, ASP.NET 4 and ASP.NET MVC 2.  NextSlide.com – a great .NET shop local to Arizona who has a great product for sharing presentations – volunteered to record the talks and publish them for free using their online presentation tool.  The recordings they did turned out really, really great – and their online player (which combines slides + camera of me + demos in one experience) is awesome.  Below you can watch the first two segments of my event – which cover VS 2010 and ASP.NET 4 – for free online using the NextSlide.com player experience.  I’ll post a link to my ASP.NET MVC 2 segment a little later in a separate blog post.  If you’ve never seen my present these talks before and are interested in the content then I’d recommend checking them out – as these recordings do a really good job capturing them. Part 1 - VS 2010 This is a 49 minute segment that starts the event and covers a bunch of the new improvements in VS 2010.  You can launch the presentation directly here or watch it inline below.  You can download powerpoint versions of my slides here. Part 2- ASP.NET 4 This 61 minute segment comes next and drills into some of the framework improvements with ASP.NET 4.  It also goes further on some of the web specific tooling improvements in VS 2010 – and towards the end demonstrates some of the great new end-to-end web deployment features provided with VS 2010 (which work for both ASP.NET Web Forms and ASP.NET MVC applications). You can launch the presentation directly here or watch it inline below: Learning More about VS 2010 and ASP.NET 4 I’ve been working on a series of blog post about VS 2010 and .NET 4.  Many of the features I covered in my two talks above are described in more detail in posts within the series.  You can read all of them here. I’ll be continuing adding to the series via my blog, so stay tuned for more in-depth posts about a bunch more new features. Hope this helps, Scott P.S. People often ask whether they can re-use the slides+demos I use in my talks for talks of their own.  The answer to this is always absolutely! No need to ask permission.  Feel free to re-use all of my slides for talks of your own. P.P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links.

• Multiple file upload with asp.net 4.5 and Visual Studio 2012

  - by Jalpesh P. Vadgama

  This post will be part of Visual Studio 2012 feature series. In earlier version of ASP.NET there is no way to upload multiple files at same time. We need to use third party control or we need to create custom control for that. But with asp.net 4.5 now its possible to upload multiple file with file upload control. With ASP.NET 4.5 version Microsoft has enhanced file upload control to support HTML5 multiple attribute. There is a property called ‘AllowedMultiple’ to support that attribute and with that you can easily upload the file. So what we are waiting for!! It’s time to create one example. On the default.aspx file I have written following. <asp:FileUpload ID="multipleFile" runat="server" AllowMultiple="true" /> <asp:Button ID="uploadFile" runat="server" Text="Upload files" onclick="uploadFile_Click"/> Here you can see that I have given file upload control id as multipleFile and I have set AllowMultiple file to true. I have also taken one button for uploading file.For this example I am going to upload file in images folder. As you can see I have also attached event handler for button’s click event. So it’s time to write server side code for this. Following code is for the server side. protected void uploadFile_Click(object sender, EventArgs e) { if (multipleFile.HasFiles) { foreach(HttpPostedFile uploadedFile in multipleFile.PostedFiles) { uploadedFile.SaveAs(System.IO.Path.Combine(Server.MapPath("~/Images/"),uploadedFile.FileName)); Response.Write("File uploaded successfully"); } } } Here in the above code you can see that I have checked whether multiple file upload control has multiple files or not and then I have save that in Images folder of web application. Once you run the application in browser it will look like following. I have selected two files. Once I have selected and clicked on upload file button it will give message like following. As you can see now it has successfully upload file and you can see in windows explorer like following. As you can see it’s very easy to upload multiple file in ASP.NET 4.5. Stay tuned for more. Till then happy programming. P.S.: This feature is only supported in browser who support HTML5 multiple file upload. For other browsers it will work like normal file upload control in asp.net.

• Python PyBluez loses Bluetooth connection after a while

  - by Travis G.

  I am using Python to write a simple serial Bluetooth script that sends information about my computer stats periodically. The receiving device is a Sparkfun BlueSmirf Silver. The problem is that, after the script runs for a few minutes, it stops sending packets to the receiver and fails with the error: (11, 'Resource temporarily unavailable') Noticing that this inevitably happens, I added some code to automatically try to reopen the connection. However, then I get: Could not connect: (16, 'Device or resource busy') Am I doing something wrong with the connection? Do I need to occasionally reopen the socket? I'm not sure how to recover from this type of error. I understand that sometimes the port will be busy and a write operation is deferred to avoid blocking other processes, but I wouldn't expect the connection to fail so regularly. Any thoughts? Here is the script: import psutil import serial import string import time import bluetooth sampleTime = 1 numSamples = 5 lastTemp = 0 TEMP_CHAR = 't' USAGE_CHAR = 'u' SENSOR_NAME = 'TC0D' #gauges = serial.Serial() #gauges.port = '/dev/rfcomm0' #gauges.baudrate = 9600 #gauges.parity = 'N' #gauges.writeTimeout = 0 #gauges.open() filename = '/sys/bus/platform/devices/applesmc.768/temp2_input' def parseSensorsOutputLinux(output): return int(round(float(output) / 1000)) def connect(): while(True): try: gaugeSocket = bluetooth.BluetoothSocket(bluetooth.RFCOMM) gaugeSocket.connect(('00:06:66:42:22:96', 1)) break; except bluetooth.btcommon.BluetoothError as error: print "Could not connect: ", error, "; Retrying in 5s..." time.sleep(5) return gaugeSocket; gaugeSocket = connect() while(1): usage = psutil.cpu_percent(interval=sampleTime) sensorFile = open(filename) temp = parseSensorsOutputLinux(sensorFile.read()) try: #gauges.write(USAGE_CHAR) gaugeSocket.send(USAGE_CHAR) #gauges.write(chr(int(usage))) #write the first byte gaugeSocket.send(chr(int(usage))) #print("Wrote usage: " + str(int(usage))) #gauges.write(TEMP_CHAR) gaugeSocket.send(TEMP_CHAR) #gauges.write(chr(temp)) gaugeSocket.send(chr(temp)) #print("Wrote temp: " + str(temp)) except bluetooth.btcommon.BluetoothError as error: print "Caught BluetoothError: ", error time.sleep(5) gaugeSocket = connect() pass gaugeSocket.close() EDIT: I should add that this code connects fine after I power-cycle the receiver and start the script. However, it fails after the first exception until I restart the receiver. P.S. This is related to my recent question, Why is /dev/rfcomm0 giving PySerial problems?, but that was more about PySerial specifically with rfcomm0. Here I am asking about general rfcomm etiquette.

• XMPP— openfire,PHP and python web service

  - by mlakhara

  I am planning to integrate real time notifications into a web application that I am currently working on. I have decided to go with XMPP for this and selected openfire server which i thought to be suitable for my needs. The front end uses strophe library to fetch the notifications using BOSH from my openfire server. However the notices are the notifications and other messages are to be posted by my application and hence I think this code needs to reside at the backend. Initially I thougt of going with PHP XMPP libraries like XMPHP and JAXL but then I think that this would cause much overhead as each script will have to do same steps like connection, authentication etc. and I think this would make the PHP end a little slow and unresponsive. Now I am thinking of creating a middle-ware application acting as a web service that the PHP will call and this application will handle the stuff with XMPP service. The benefit with this is that this app(a server if you will) will have to connect just once and the it will sit there listening on a port. also I am planning to build it in a asynchronous way such that It will first take all the requests from my PHp app and then when there are no more requests; go about doing the notification publishing stuff. I am planninng to create this service in Python using SleekXMPP. This is just what I planned. I am new to XMPP and this whole web service stuff ans would like to take your comments on this regarding issues like memory and CPU usage, advantages, disadvantages, scalability issues,security etc. Thanks in advance. PS:-- also if something like this already exists(although I didn't find after a lot of Googling) Please direct me there. EDIT --- The middle-level service should be doing the following(but not limited to): 1. Publishing notifications for different level of groups and community pages. 2. Notification for single user on some event. 3. User registration(can be done using user service plugin though). EDIT --- Also it should like to create pub-sub nodes and subscribe and unsubscribe users from these pub-sub nodes. Also I want to store the notifications and messages in a database(openfire doesn't). Would that be a good choice?

• Internet doesn't work by default

  After upgrading to Precise, I am required to run 'sudo dhclient eth0' in a terminal in order to get the internet to work. Everything worked perfectly fine on Oneiric, so It's really puzzling me. I'm thinking it could possibly be something with the kernel, but who knows.

• Some of my favourite Visual Studio 2012 things&ndash;Teams

  - by Aaron Kowall

  Getting the balance right for when and how many team projects to create has always been a bit of a balance.  On large initiatives, there are often teams who work toward a common system.  These teams often have quite a bit of autonomy, but need to roll up to some higher level initiative.  In TFS 2010, people were often tempted to create separate Team Projects for each of the sub-teams and then do some magic with reporting and cross-team queries to get the consolidated view.  My recommendation was always to use Areas as a means of separating work across the team, but that always resulted in a large number of queries that need to be maintained and just seemed confusing.  When doing anything you had to remember to filter the query or view by Area in order to get correct results. Along with the awesome web access portal that comes in TFS 2012 (which I will cover details of in another post) the product group has introduced the concept of Teams.  A team is a sub-group within a TFS 2012 Team Project which allows us to more easily divide work along team boundaries. Technically, a Team is defined by an Area Path and a TFS Group, both of which could be done in TFS 2012.  However, by allowing for creation of a ‘Team’ in TFS 2012, the web portal is able to do a bunch of ‘magic’ for us.  We can view the project site (backlog, taskboard, etc) for the the team, we can assign items to the team and we can view the burndown for the team.  Basically, all the stuff that we had to prepare manually we now get created and managed for us with a nice UI. When you create a Team Project in TFS 2012, a ‘Default’ team is created with the same name as the Team Project.  So, if you only have 1 team working on the project, you are set.  If you want to divide the work into additional teams, you can create teams by using the Team Web Client.

• Development processes, the use of version control, and unit-testing

  - by ct01

  Preface I've worked at quite a few "flat" organizations in my time. Most of the version control policy/process has been "only commit after it's been tested". We were constantly committing at each place to "trunk" (cvs/svn). The same was true with unit-testing - it's always been a "we need to do this" mentality but it never really materializes in a substantive form b/c there is no institutional knowledge base to do it - no mentorship. Version Control The emphasis for version control management at one place was a very strict protocol for commit messages (format & content). The other places let employees just do "whatever". The branching, tagging, committing, rolling back, and merging aspect of things was always ill defined and almost never used. This sort of seems to leave the version control system in the position of being a fancy file-storage mechanism with a meta-data component that never really gets accessed/utilized. (The same was true for unit testing and committing code to the source tree) Unit tests It seems there's a prevailing "we must/should do this" mentality in most places I've worked. As a policy or standard operating procedure it never gets implemented because there seems to be a very ill-defined understanding about what that means, what is going to be tested, and how to do it. Summary It seems most places I've been to think version control and unit testing is "important" b/c the trendy trade journals say it is but, if there's very little mentorship to use these tools or any real business policies, then the full power of version control/unit testing is never really expressed. So grunts, like myself, never really have a complete understanding of the point beyond that "it's a good thing" and "we should do it". Question I was wondering if there are blogs, books, white-papers, or online journals about what one could call the business process or "standard operating procedures" or uses cases for version control and unit testing? I want to know more than the trade journals tell me and get serious about doing these things. PS: @Henrik Hansen had a great comment about the lack of definition for the question. I'm not interested in a specific unit-testing/versioning product or methodology (like, XP) - my interest is more about work-flow at the individual team/developer level than evangelism. This is more-or-less a by product of the management situation I've operated under more than a lack of reading software engineering books or magazines about development processes. A lot of what I've seen/read is more marketing oriented material than any specifically enumerated description of "well, this is how our shop operates".

• Monogame/SharpDX - Shader parameters missing

  - by Layoric

  I am currently working on a simple game that I am building in Windows 8 using MonoGame (develop3d). I am using some shader code from a tutorial (made by Charles Humphrey) and having an issue populating a 'texture' parameter as it appears to be missing. Edit I have also tried 'Texture2D' and using it with a register(t0), still no luck I'm not well versed writing shaders, so this might be caused by a more obvious problem. I have debugged through MonoGame's Content processor to see how this shader is being parsed, all the non 'texture' parameters are there and look to be loading correctly. Edit This seems to go back to D3D compiler. Shader code below: #include "PPVertexShader.fxh" float2 lightScreenPosition; float4x4 matVP; float2 halfPixel; float SunSize; texture flare; sampler2D Scene: register(s0){ AddressU = Clamp; AddressV = Clamp; }; sampler Flare = sampler_state { Texture = (flare); AddressU = CLAMP; AddressV = CLAMP; }; float4 LightSourceMaskPS(float2 texCoord : TEXCOORD0 ) : COLOR0 { texCoord -= halfPixel; // Get the scene float4 col = 0; // Find the suns position in the world and map it to the screen space. float2 coord; float size = SunSize / 1; float2 center = lightScreenPosition; coord = .5 - (texCoord - center) / size * .5; col += (pow(tex2D(Flare,coord),2) * 1) * 2; return col * tex2D(Scene,texCoord); } technique LightSourceMask { pass p0 { VertexShader = compile vs_4_0 VertexShaderFunction(); PixelShader = compile ps_4_0 LightSourceMaskPS(); } } I've removed default values as they are currently not support in MonoGame and also changed ps and vs to v4 instead of 2. Could this be causing the issue? As I debug through 'DXConstantBufferData' constructor (from within the MonoGameContentProcessing project) I find that the 'flare' parameter does not exist. All others seem to be getting created fine. Any help would be appreciated. Update 1 I have discovered that SharpDX D3D compiler is what seems to be ignoring this parameter (perhaps by design?). The ConstantBufferDescription.VariableCount seems to be not counting the texture variable. Update 2 SharpDX function 'GetConstantBuffer(int index)' returns the parameters (minus textures) which is making is impossible to set values to these variables within the shader. Any one know if this is normal for DX11 / Shader Model 4.0? Or am I missing something else?

• Macbook Pro 13" Retina (10,2): Keyboard and Touchpad don't work correcltly

  - by Dirk

  I'm dealing with Ubuntu since about 5 years and installed it on several laptops. Now I'm stuck when trying to install Ubuntu 12.04.1 on a brand new Macbook Pro 13" Retina (10,2). I sucessfully can start Ubuntu from an USB stick, the Ubuntu desktop is visible, a mouse cursor is visible. But there is no respond to keyboard or touchpad input. So I cannot really install Ubuntu on the Macbook. The details of my approach: Prepare an empty USB stick Download "ISO 2 USB EFI Booter for Mac" and copy the file bootX64.efi to the USB drive as /efi/boot/bootX64.efi. Download Ubuntu 12.04.1 Desktop for Mac from http://cdimage.ubuntu.com/releases/1-amd64+mac.iso and copy the iso the USB drive as /efi/boot/boot.iso Put the USB stick into the Macbook Press and hold the "alt" button while switching the Macbook on Select "EFI Boot" from the boot menu that appears and press the Return / Enter key Immediately a black terminal screen appears with the headline "Welcome to the Ubuntu ISO << - EFI booter". 30 seconds later the familiar Ubuntu startup graphics screen is showing. Further 20 seconds later Ubuntu has started and the desktop is visible - in wonderfully fine resolution Now the computer does not respond to any actions on the touchpad nor the keyboard Who did install Ubuntu on this Macbook Pro 13" Retina (10,2) successfully? On this site https://help.ubuntu.com/community/MacBookPro this unit is not listed yet, anyway. Any help would be greatly appreciated! Dirk PS: I could now install ubuntu with an external USB Keyboard/Mouse Set. But now, after showing the grub menu, a kernel panic error appears and booting stops :-/ Seems that the ubuntu images fit not to a macbook pro retina 13" (10,2) yet. PPS: Ok, there are new facts: If I edit the boot options and enter " nomodeset noapic" ubuntu starts and Keyboard and Touchpad work! Now I have to enable WiFi... PPPS: After installing Broadcom firmware from USB Live stick as described in other posts, WiFi was enabled. Then I could update ubuntu normally to 12.10. After this, I must not enter "nomodeset noapic" in the grub menu anymore. Last Thing now is the Touchpad. The driver seems not to be there. The touch pad is only showing as mouse. t.b.c.

• What is hogging my connection?

  - by SF.

  At times it seems like dozens, if not hundreds of root-owned HTTP connections spring up. This is not much of a problem on LAN or WLAN as each of them seems to transfer very little, but if I use GPRS link, my ping times go into minutes (seriously, 80000ms is not infrequent!) and all connections grind to a halt waiting till these end. This usually lasts some 15 minutes and ends about when I start troubleshooting it for real. I've managed to capture a fragment of Nethogs output NetHogs version 0.8.0 PID USER PROGRAM DEV SENT RECEIVED ? root 37.209.147.180:59854-141.101.114.59:80 0.013 0.000 KB/sec ? root 37.209.147.180:59853-141.101.114.59:80 0.000 0.000 KB/sec ? root 37.209.147.180:52804-173.194.70.95:80 0.000 0.000 KB/sec 1954 bw /home/bw/.dropbox-dist/dropbox ppp0 0.000 0.000 KB/sec ? root 37.209.147.180:59851-141.101.114.59:80 0.000 0.000 KB/sec ? root 37.209.147.180:59850-141.101.114.59:80 0.000 0.000 KB/sec ? root 37.209.147.180:52801-173.194.70.95:80 0.000 0.000 KB/sec 13301 bw /usr/lib/firefox/firefox ppp0 0.000 0.000 KB/sec ? root unknown TCP 0.000 0.000 KB/sec Unfortunately, it doesn't display the owning process of these.

• Looking for best practice for version numbering of dependent software components

  - by bit-pirate

  We are trying to decide on a good way to do version numbering for software components, which are depending on each other. Let's be more specific: Software component A is a firmware running on an embedded device and component B is its respective driver for a normal PC (Linux/Windows machine). They are communicating with each other using a custom protocol. Since, our product is also targeted at developers, we will offer stable and unstable (experimental) versions of both components (the firmware is closed-source, while the driver is open-source). Our biggest difficulty is how to handle API changes in the communication protocol. While we were implementing a compatibility check in the driver - it checks if the firmware version is compatible to the driver's version - we started to discuss multiple ways of version numbering. We came up with one solution, but we also felt like reinventing the wheel. That is why I'd like to get some feedback from the programmer/software developer community, since we think this is a common problem. So here is our solution: We plan to follow the widely used major.minor.patch version numbering and to use even/odd minor numbers for the stable/unstable versions. If we introduce changes in the API, we will increase the minor number. This convention will lead to the following example situation: Current stable branch is 1.2.1 and unstable is 1.3.7. Now, a new patch for unstable changes the API, what will cause the new unstable version number to become 1.5.0. Once, the unstable branch is considered stable, let's say in 1.5.3, we will release it as 1.4.0. I would be happy about an answer to any of the related questions below: Can you suggest a best practice for handling the issues described above? Do you think our "custom" convention is good? What changes would you apply to the described convention? Thanks a lot for your feedback! PS: Since I'm new here, I can't create new tags (e.g. best-practice). So, I'm wondering if best-pactice is just misspelled or I don't get its meaning.

• How to implement line of sight restriction in actionscript?

  - by Michiel Standaert

  I have a problem with a game i am programming. I am making some sort of security game and i would like to have some visual line of sight. The problem is that i can't restrict my line of sight so my cops can't see through the walls. Below you find the design, in which they can look through windows, but not walls. Further below you find an illustration of what my problem is exactly. this is what it looks like now. As you can see, the cops can see through walls. This is the map i would want to use to restrict the line of sight. So the way i am programming the line of sight now is just by calculating some points and drawing the sight accordingly, as shown below. Note that i also check for a hittest using bitmapdata to check whether or not my player has been spotted by any of the cops. private function setSight(e:Event=null):Boolean { g = copCanvas.graphics; g.clear(); for each(var cop:Cop in copCanvas.getChildren()) { var _angle:Number = cop.angle; var _radians:Number = (_angle * Math.PI) / 180; var _radius:Number = 50; var _x1:Number = cop.x + (cop.width/2); var _y1:Number = cop.y + (cop.height/2); var _baseX:Number = _x1 + (Math.cos(_radians) * _radius); var _baseY:Number = _y1 - (Math.sin(_radians) * _radius); var _x2:Number = _baseX + (25 * Math.sin(_radians)); var _y2:Number = _baseY + (25 * Math.cos(_radians)); var _x3:Number = _baseX - (25 * Math.sin(_radians)); var _y3:Number = _baseY - (25 * Math.cos(_radians)); g.beginFill(0xff0000, 0.3); g.moveTo(_x1, _y1); g.lineTo(_x2, _y2); g.lineTo(_x3, _y3); g.endFill(); } var _cops:BitmapData = new BitmapData(width, height, true, 0); _cops.draw(copCanvas); var _bmpd:BitmapData = new BitmapData(10, 10, true, 0); _bmpd.draw(me); if(_cops.hitTest(new Point(0, 0), 10, _bmpd, new Point(me.x, me.y), 255)) { gameover.alpha = 1; setTimeout(function():void{ gameover.alpha = 0; }, 5000); stop(); return true; } return false; } So now my question is: Is there someone who knows how to restrict the view so that the cops can't look through the walls? Thanks a lot in advance. ps: i have already looked at this tutorial by emanuele feronato, but i can't use the code to restric the visual line of sight.

• Voxel Face Crawling (Mesh simplification, possibly using greedy)

  - by Tim Winter

  This is in regards to a Minecraft-like terrain engine. I store blocks in chunks (16x256x16 blocks in a chunk). When I generate a chunk, I use multiple procedural techniques to set the terrain and to place objects. While generating, I keep one 1D array for the full chunk (solid or not) and a separate 1D array of solid blocks. After generation, I iterate through the solid blocks checking their neighbors so I only generate block faces that don't have solid neighbors. I store which faces to generate in their own list (that's 6 lists, one per possible face). When rendering a chunk, I render all lists in the camera's current chunk and only the lists facing the camera in all other chunks. Using a 2D atlas with this little shader trick Andrew Russell suggested, I want to merge similar faces together completely. That is, if they are in the same list (same normal), are adjacent to each other, have the same light level, etc. My assumption would be to have each of the 6 lists sorted by the axis they rest on, then by the other two axes (the list for the top of a block would be sorted by it's Y value, then X, then Z). With this alone, I could quite easily merge strips of faces, but I'm looking to merge more than just strips together when possible. I've read up on this greedy meshing algorithm, but I am having a lot of trouble understanding it. To even use it, I would think I'd need to perform a type of flood-fill per sorted list to get the groups of merge-able faces. Then, per group, perform the greedy algorithm. It all sounds awfully expensive if I would ever want dynamic terrain/lighting after initial generation. So, my question: To perform merging of faces as described (ignoring whether it's a bad idea for dynamic terrain/lighting), is there perhaps an algorithm that is simpler to implement? I would also quite happily accept an answer that walks me through the greedy algorithm in a much simpler way (a link or explanation). I don't mind a slight performance decrease if it's easier to implement or even if it's only a little better than just doing strips. I worry that most algorithms focus on triangles rather than quads and using a 2D atlas the way I am, I don't know that I could implement something triangle based with my current skills. PS: I already frustum cull per chunk and as described, I also cull faces between solid blocks. I don't occlusion cull yet and may never.

• Windows Phone 7 Developer Tools - January 2011 Update

  - by Nikita Polyakov

  Long time no talk? So to make up for it, here is something very new – update to WP7 Dev Tools! The Windows Phone 7 Developer Tools January 2011 Update provides bits that you would install on TOP of the current WP7 Dev tools on your machine. If you are just installing the tools for the first time, this update replaces previously released October patch. In fact, it is no longer available as this January 2011 update replaces the patch entirely. What is in this update? TextBox support for Copy&Paste Updated Emulator Image that contains Copy&Paste for your testing There have been performance tweaks for the OS Minor Bugs and Fixes How does it Work? The Copy&Paste extends a existing TextBox control to have this new functionality, There is no current API access to the Clipboard or support for other controls that are not based on TextBox. If I have/Do I need to: A current application in the marketplace/No action is required Have an application that contains a TextBox in a Pivot or Panorama control surface/Text your application in provided emulator Recommendation is to move TextBox controls from directly top of controls that listen to Gesture movement to their own pop-off screens or entire pages as this might interfear with select behavior for Copy&Paste Have controls that do no inherit from TextBox/Such controls will not get new Copy&Paste behavior Note: The update materials, FAQ and Q&A do not answer WHEN the update for the OS will be sent to the phones.  Also to note - this update does NOT update your developer phone to enable Copy&Paste or any other features. Windows Phone 7 Training Kit February Update Windows Phone Training Kit has also been updated – you can grab a fresh copy here.   Where to I find more good information, documentation and training? This very awesome blog post from the Windows Phone Developer Blog - Windows Phone 7 Documentation Landscape. Official Blog Post on the Update is here. Happy coding! -Nikita   PS: I am well aware that it is Feb 4th and not January :) If you were disappointed at CES that Microsoft said nothing at all about future of WP7, don’t forget that MWC 2011 is Feb 14th – I am going to be listening for Windows Phone announcements then, as that is where the announcements were made about Windows Phone 7.

• Mathemagics - 3 consecutive number

  - by PointsToShare

  © 2011 By: Dov Trietsch. All rights reserved Three Consecutive numbers When I was young and handsome (OK, OK, just young), my father used to challenge us with riddles and tricks involving Logic, Math and general knowledge. Most of the time, at least after reaching the ripe age of 10, I would see thru his tricks in no time. This one is a bit more subtle. I had to think about it for close to an hour and then when I had the ‘AHA!’ effect, I could not understand why it had taken me so long. So here it is. You select a volunteer from the audience (or a shill, but that would be cheating!) and ask him to select three consecutive numbers, all of them 1 or 2 digits. So {1, 2, 3} would be good, albeit trivial set, as would {8, 9, 10} or {97, 98, 99} but not {99, 99, 100} (why?!). Now, using a calculator – and these days almost every phone has a built in calculator – he is to perform these steps: 1.      Select a single digit 2.      Multiply it by 3 and write it down 3.      Add the 3 consecutive numbers 4.      Add the number from step 2 5.      Multiply the sum by 67 6.      Now tell me the last 2 digits of the result and also the number you wrote down in step 2 I will tell you which numbers you selected. How do I do this? I’ll give you the mechanical answer, but because I like you to have the pleasure of an ‘AHA!’ effect, I will not really explain the ‘why’. So let’s you selected 30, 31, and 32 and also that your 3 multiple was 24, so here is what you get 30 + 31 + 32 = 93 93 + 24 = 117 117 x 67 = 7839, last 2 digits are 39, so you say “the last 2 digits are 39, and the other number is 24.” Now, I divide 24 by 3 getting 8. I subtract 8 from 39 and get 31. I then subtract 1 from this getting 30, and say: “You selected 30, 31, and 32.” This is the ‘how’. I leave the ‘why’ to you! That’s all folks! PS do you really want to know why? Post a feedback below. When 11 people or more will have asked for it, I’ll add a link to the full explanation.

• Character Stats and Power

  - by Stephen Furlani

  I'm making an RPG game system and I'm having a hard time deciding on doing detailed or abstract character statistics. These statistics define the character's natural - not learned - abilities. For example: Mass Effect: 0 (None that I can see) X20 (Xtreme Dungeon Mastery): 1 "STAT" Diablo: 4 "Strength, Magic, Dexterity, Vitality" Pendragon: 5 "SIZ, STR, DEX, CON, APP" Dungeons & Dragons (3.x, 4e): 6 "Str, Dex, Con, Wis, Int, Cha" Fallout 3: 7 "S.P.E.C.I.A.L." RIFTS: 8 "IQ, ME, MA, PS, PP, PE, PB, Spd" Warhammer Fantasy Roleplay (1st ed?): 12-ish "WS, BS, S, T, Ag, Int, WP, Fel, A, Mag, IP, FP" HERO (5th ed): 14 "Str, Dex, Con, Body, Int, Ego, Pre, Com, PD, ED, Spd, Rec, END, STUN" The more stats, the more complex and detailed your character becomes. This comes with a trade-off however, because you usually only have limited resources to describe your character. D&D made this infamous with the whole min/max-ing thing where strong characters were typically not also smart. But also, a character with a high Str typically also has high Con, Defenses, Hit Points/Health. Without high numbers in all those other stats, they might as well not be strong since they wouldn't hold up well in hand-to-hand combat. So things like that force trade-offs within the category of strength. So my original (now rejected) idea was to force players into deciding between offensive and defensive stats: Might / Body Dexterity / Speed Wit / Wisdom Heart Soul But this left some stat's without "opposites" (or opposites that were easily defined). I'm leaning more towards the following: Body (Physical Prowess) Mind (Mental Prowess) Heart (Social Prowess) Soul (Spiritual Prowess) This will define a character with just 4 numbers. Everything else gets based off of these numbers, which means they're pretty important. There won't, however, be ways of describing characters who are fast, but not strong or smart, but absent minded. Instead of defining the character with these numbers, they'll be detailing their character by buying skills and powers like these: Quickness Add a +2 Bonus to Body Rolls when Dodging. for a character that wants to be faster, or the following for a big, tough character Body Building Add a +2 Bonus to Body Rolls when Lifting, Pushing, or Throwing objects. [EDIT - removed subjectiveness] So my actual questions is what are some pitfalls with a small stat list and a large amount of descriptive powers? Is this more difficult to port cross-platform (pen&paper, PC) for example? Are there examples of this being done well/poorly? Thanks,

• Coding different states in Adventure Games

  - by Cardin

  I'm planning out an adventure game, and can't figure out what's the right way to implement the behaviour of a level depending on state of story progression. My single-player game features a huge world where the player has to interact with people in a town at various points in the game. However, depending on story progression, different things would be presented to the player, for e.g. the Guild Leader will change locations from the town square to various locations around the city; Doors would only unlock at certain times of the day after finishing a particular routine; Different cut-screen/trigger events happen only after a particular milestone has been reached. I naively thought of using a switch{} statement initially to decide what the NPC should say or which he could be found at, and making quest objectives interact-able only after checking a global game_state variable's condition. But I realised I would quickly run into a lot of different game states and switch-cases in order to change the behaviour of an object. That switch statement would also be massively hard to debug, and I guess it might also be hard to use in a level editor. So I thought, instead of having a single object with multiple states, maybe I should have multiple instances of the same object, with a single state. That way, if I use something like a level editor, I can put an instance of the NPC at all the different locations he could ever appear at, and also an instance for each conversation state he has. But that means there'll be a lot of inactive, invisible game objects floating around the level, which might be trouble for memory, or simply hard to see in a level editor, i don't know. Or simply, make an identical, but separate level for each game state. This feels the cleanest and bug-free way to do things, but it feels like massive manual work making sure each version of the level is really identical to each other. All my methods feel so inefficient, so to recap my question, is there a better or standardised way to implement behaviour of a level depending on state of story progression? PS: I don't have a level editor yet - thinking of using something like JME SDK or making my own.
