• why is emacs allowing multiple instances?

  - by Chad

  Around the time I fresh installed Ubuntu 12.04, I noticed that I can start multiple instances of Emacs. I find this annoying because I will think that a buffer should be open, but I'm in the wrong Emacs window. I may have changed something in .emacs, but I really don't think I did. I also reverted all of my customizations that are stored in ~/.emacs.d/custom.el. Emacs previously would give some error about another emacs server being open when I would attempt to start an additional instance of it, but it no longer does this. Any ideas on how to restore this behavior?

• Detecting collision between ball (circle) and brick(rectangle)?

  - by James Harrison

  Ok so this is for a small uni project. My lecturer provided me with a framework for a simple brickbreaker game. I am currently trying to overcome to problem of detecting a collision between the two game objects. One object is always the ball and the other objects can either be the bricks or the bat. public Collision hitBy( GameObject obj ) { //obj is the bat or the bricks //the current object is the ball // if ball hits top of object if(topX + width >= obj.topX && topX <= obj.topX + obj.width && topY + height >= obj.topY - 2 && topY + height <= obj.topY){ return Collision.HITY; } //if ball hits left hand side else if(topY + height >= obj.topY && topY <= obj.topY + obj.height && topX + width >= obj.topX -2 && topX + width <= obj.topX){ return Collision.HITX; } else return Collision.NO_HIT; } So far I have a method that is used to detect this collision. The the current obj is a ball and the obj passed into the method is the the bricks. At the moment I have only added statement to check for left and top collisions but do not want to continue as I have a few problems. The ball reacts perfectly if it hits the top of the bricks or bat but when it hits the ball often does not change directing. It seems that it is happening toward the top of the left hand edge but I cannot figure out why. I would like to know if there is another way of approaching this or if people know where I'm going wrong. Lastly the collision.HITX calls another method later on the changes the x direction likewise with y.

• Skip the first RenderTarget when writing to MRT with Opaque blending

  - by cubrman

  I am writing to three rendertargets and whant to know how to tell a GPU not to write to the first RT. When you write a shader you can simply output less data than you have RTs (like output a single float4 when writing to three RTs) and only the first RTs will be affected, but you cannot specify to output this data anywhere else but to COLOR0, then 1, etc. Is there a way to write to several RTs but skip the first target? If I output zeroes, the data in the target will become zeroes, but I need it to remain untuched in the first target and only change in the specified ones. The reason I need this is to prevent data loss when calling SetRendertarget() with DiscardContents RTs. I write to all the RTs at one point and I need to write to only the specified ones afterwards. It must be the first texture as I have a depth buffer linked to it (XNA 4.0). Thanks.

• cpufreq-selector, cpufreq-info reporting wrong max speed

  - by dty

  Hi, I've just built a new machine with a Core i5-760 CPU. Max speed is 2.80GHz (turbo mode notwithstanding). I've also done a vanilla install of Ubuntu 10.10. I've added the cpufreq-selector applet to the top panel, and its menus only allow me to select up to 2.39GHz. If I select the "performance" governor, it also shows 2.39GHz. cpufreq-info reports: $ cpufreq-info cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to [email protected], please. analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 1 2 3 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us. hardware limits: 1.20 GHz - 2.39 GHz available frequency steps: 2.39 GHz, 2.26 GHz, 2.13 GHz, 2.00 GHz, 1.86 GHz, 1.73 GHz, 1.60 GHz, 1.46 GHz, 1.33 GHz, 1.20 GHz available cpufreq governors: conservative, ondemand, userspace, powersave, performance current policy: frequency should be within 1.20 GHz and 2.39 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 1.20 GHz. cpufreq stats: 2.39 GHz:13.74%, 2.26 GHz:0.09%, 2.13 GHz:0.08%, 2.00 GHz:0.08%, 1.86 GHz:0.07%, 1.73 GHz:0.07%, 1.60 GHz:0.08%, 1.46 GHz:0.08%, 1.33 GHz:0.11%, 1.20 GHz:85.61% (15560) [...CPUs 1-3 elided, but similar...] Any idea how to get Ubuntu and the various tools to recognise this as a 2.80GHz processor? And ideally to report the actual speed when running in turbo mode too, but that's not critical. Edit: I should probably add that the BIOS (& Windows) are quite happy that it's a 2.80GHz CPU. Thanks.

• Date header returned by IIS7 is wrong

  - by James Hollingworth

  I am serving an ASP.NET application from IIS 7 but we are experiencing some weird cookie issues. The code works fine in other environments so we are assuming this is specific to this server (related question). We have been looking at the http headers returned and someone pointed out that the date http header is showing the 1st of Jan rather than today's date (so far it always shows that date regardless of what the current date is). The system clock is set correctly (and we can print out the current time/date via DateTime.Now correctly as well) so we can't work out why it's now working. Does anyone have any ideas? Is this a red-herring? Thanks, James

• nVidia GeForce Go 7600? can it ever run unity?

  - by Khaled Musleh

  my laptop Toshiba Qosmio G30 has nVidia GeForce Go 7600 card and it suppose to support 3D . i run unity 2d now . I run 12.04 and the graphic driver is--VESA: G73 Board - toshg73m-- by UBUNTU. when i run /usr/lib/nux/unity_support_test -p then i get this list Not software rendered: no Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no the card is not blacklisted but a similar one with GT is! Do you think that there is a chance the laptop can run the unity 3d? and may be i could change the resolution of the screen to a higher one too! I tried all the nvidia drivers provided but none works (except 96 in ubuntu 12.04 ). i get a black screen or terminal screen. best wishes to all

• HP Smart Array; Is it possible to convert Raid1 to Raid0 by dropping a failed drive?

  - by Erik Heppler

  I have a server that was running two 60GB drives as a logical RAID1. At some point the second drive was physically removed and the logical drive has been in "Interim Recovery Mode" for several months now. There's no need for the redundancy of RAID1 on this machine, and I have no intention of replacing the missing drive. If possible I would like to convert the current RAID1 to a single-drive RAID0 by simply dropping the failed drive from the current configuration. I'm only interested in doing this if it can be done in-place. Otherwise I'm perfectly content to leave it in "Interim Recovery Mode" indefinitely.

• How can i update Preview.app from the command line without loosing focus on OSX ?

  - by snies

  Hello, i want to update Preview.app in the background from the command line without loosing focus of my current window. I know that i can use the following to open/update the view of a file, but than i loose focus to the Preview.app. open -a Preview foo.pdf I guess there might be some clever Apple Script commands to do so but so far i didn't find the right one. Alternatively i would be interested into transfering the focus back to my current app directly after the update. I need this in order to update Preview.app's view of a pdf through a vi autocmd after i update the pdf according to changes in a tex file i am editing. Here is an example of what i want to achive but using Ubuntu and evince.

• Animation API vs frame animation

  - by Max

  I'm pretty far down the road in my game right now, closing in on the end. And I'm adding little tweaks here and there. I used custom frame animation of a single image with many versions of my sprite on it, and controlled which part of the image to show using rectangles. But I'm starting to think that maybe I should've used the Animation API that comes with android instead. Will this effect my performance in a negative way? Can I still use rectangles to draw my bitmap? Could I add effects from the Animation API to my current frame-controlled animation? like the fadeout-effect etc? this would mean I wont have to change my current code. I want some of my animations to fade out, and just noticed that using the Animation API makes things alot easier. But needless to say, I would prefer not having to change all my animation-code. I'm bad at explaining, so Ill show a bit of how I do my animation: private static final int BMP_ROWS = 1; //I use top-view so only need my sprite to have 1 direction private static final int BMP_COLUMNS = 3; public void update(GameControls controls) { if (sprite.isMoving) { currentFrame = ++currentFrame % BMP_COLUMNS; } else { this.setFrame(1); } } public void draw(Canvas canvas, int x, int y, float angle) { this.x=x; this.y=y; canvas.save(); canvas.rotate(angle , x + width / 2, y + height / 2); int srcX = currentFrame * width; int srcY = 0 * height; Rect src = new Rect(srcX, srcY, srcX + width, srcY + height); Rect dst = new Rect(x, y, x + width, y + height); canvas.drawBitmap(bitmap, src, dst, null); canvas.restore(); }

• Black Screen: How to set Projection/View Matrix

  - by Lisa

  I have a Windows Phone 8 C#/XAML with DirectX component project. I'm rendering some particles, but each particle is a rectangle versus a square (as I've set the vertices to be positions equally offset from each other). I used an Identity matrix in the view and projection matrix. I decided to add the windows aspect ratio to prevent the rectangles. But now I get a black screen. None of the particles are rendered now. I don't know what's wrong with my matrices. Can anyone see the problem? These are the default matrices in Microsoft's project example. View Matrix: XMVECTOR eye = XMVectorSet(0.0f, 0.7f, 1.5f, 0.0f); XMVECTOR at = XMVectorSet(0.0f, -0.1f, 0.0f, 0.0f); XMVECTOR up = XMVectorSet(0.0f, 1.0f, 0.0f, 0.0f); XMStoreFloat4x4(&m_constantBufferData.view, XMMatrixTranspose(XMMatrixLookAtRH(eye, at, up))); Projection Matrix: void CubeRenderer::CreateWindowSizeDependentResources() { Direct3DBase::CreateWindowSizeDependentResources(); float aspectRatio = m_windowBounds.Width / m_windowBounds.Height; float fovAngleY = 70.0f * XM_PI / 180.0f; if (aspectRatio < 1.0f) { fovAngleY /= aspectRatio; } XMStoreFloat4x4(&m_constantBufferData.projection, XMMatrixTranspose(XMMatrixPerspectiveFovRH(fovAngleY, aspectRatio, 0.01f, 100.0f))); } I've tried modifying them to use cocos2dx's WP8 example. XMMATRIX identityMatrix = XMMatrixIdentity(); float fovy = 60.0f; float aspect = m_windowBounds.Width / m_windowBounds.Height; float zNear = 0.1f; float zFar = 100.0f; float xmin, xmax, ymin, ymax; ymax = zNear * tanf(fovy * XM_PI / 360); ymin = -ymax; xmin = ymin * aspect; xmax = ymax * aspect; XMMATRIX tmpMatrix = XMMatrixPerspectiveOffCenterRH(xmin, xmax, ymin, ymax, zNear, zFar); XMMATRIX projectionMatrix = XMMatrixMultiply(tmpMatrix, identityMatrix); // View Matrix float fEyeX = m_windowBounds.Width * 0.5f; float fEyeY = m_windowBounds.Height * 0.5f; float fEyeZ = m_windowBounds.Height / 1.1566f; float fLookAtX = m_windowBounds.Width * 0.5f; float fLookAtY = m_windowBounds.Height * 0.5f; float fLookAtZ = 0.0f; float fUpX = 0.0f; float fUpY = 1.0f; float fUpZ = 0.0f; XMMATRIX tmpMatrix2 = XMMatrixLookAtRH(XMVectorSet(fEyeX,fEyeY,fEyeZ,0.f), XMVectorSet(fLookAtX,fLookAtY,fLookAtZ,0.f), XMVectorSet(fUpX,fUpY,fUpZ,0.f)); XMMATRIX viewMatrix = XMMatrixMultiply(tmpMatrix2, identityMatrix); XMStoreFloat4x4(&m_constantBufferData.view, viewMatrix); Vertex Shader cbuffer ModelViewProjectionConstantBuffer : register(b0) { //matrix model; matrix view; matrix projection; }; struct VertexInputType { float4 position : POSITION; float2 tex : TEXCOORD0; float4 color : COLOR; }; struct PixelInputType { float4 position : SV_POSITION; float2 tex : TEXCOORD0; float4 color : COLOR; }; PixelInputType main(VertexInputType input) { PixelInputType output; // Change the position vector to be 4 units for proper matrix calculations. input.position.w = 1.0f; //===================================== // TODO: ADDED for testing input.position.z = 0.0f; //===================================== // Calculate the position of the vertex against the world, view, and projection matrices. //output.position = mul(input.position, model); output.position = mul(input.position, view); output.position = mul(output.position, projection); // Store the texture coordinates for the pixel shader. output.tex = input.tex; // Store the particle color for the pixel shader. output.color = input.color; return output; } Before I render the shader, I set the view/projection matrices into the constant buffer void ParticleRenderer::SetShaderParameters() { ViewProjectionConstantBuffer* dataPtr; D3D11_MAPPED_SUBRESOURCE mappedResource; DX::ThrowIfFailed(m_d3dContext->Map(m_constantBuffer.Get(), 0, D3D11_MAP_WRITE_DISCARD, 0, &mappedResource)); dataPtr = (ViewProjectionConstantBuffer*)mappedResource.pData; dataPtr->view = m_constantBufferData.view; dataPtr->projection = m_constantBufferData.projection; m_d3dContext->Unmap(m_constantBuffer.Get(), 0); // Now set the constant buffer in the vertex shader with the updated values. m_d3dContext->VSSetConstantBuffers(0, 1, m_constantBuffer.GetAddressOf() ); // Set shader texture resource in the pixel shader. m_d3dContext->PSSetShaderResources(0, 1, &m_textureView); } Nothing, black screen... I tried so many different look at, eye, and up vectors. I tried transposing the matrices. I've set the particle center position to always be (0, 0, 0), I tried different positions too, just to make sure they're not being rendered offscreen.

• Antenna Aligner part 2: Finding the right direction

  - by Chris George

  Last time I managed to get "my first app(tm)" built, published and running on my iPhone. This was really cool, a piece of my code running on my very own device. Ok, so I'm easily pleased! The next challenge was actually trying to determine what it was I wanted this app to do, and how to do it. Reverting back to good old paper and pen, I started sketching out designs for the app. I knew I wanted it to get a list of transmitters, then clicking on a transmitter would display a compass type view, with an arrow pointing the right way. I figured there would not be much point in continuing until I know I could do the graphical part of the project, i.e. the rotating compass, so armed with that reasoning (plus the fact I just wanted to get on and code!), I once again dived into visual studio. Using my friend (google) I found some example code for getting the compass data from the phone using the PhoneGap framework. // onSuccess: Get the current heading // function onSuccess(heading) {    alert('Heading: ' + heading); } navigator.compass.getCurrentHeading(onSuccess, onError); Using the ripple mobile emulator this showed that it was successfully getting the compass heading. But it didn't work when uploaded to my phone. It turns out that the examples I had been looking at were for PhoneGap 1.0, and Nomad uses PhoneGap 1.4.1. In 1.4.1, getCurrentHeading provides a compass object to onSuccess, not just a numeric value, so the code now looks like // onSuccess: Get the current magnetic heading // function onSuccess(heading) {    alert('Heading: ' + heading.magneticHeading); }; navigator.compass.getCurrentHeading(onSuccess, onError); So the lesson learnt from this... read the documentation for the version you are actually using! This does, however, lead to compatibility problems with ripple as it only supports 1.0 which is a real pain. I hope that the ripple system is updated sometime soon.

• Loading main javascript on every page? Or breaking it up to relevant pages?

  - by Kyle

  I have a 700kb decompressed JS file which is loaded on every page. Before I had 12 javascript files on each page but to reduce http requests I compressed them all into 1 file. This file is ~130kb gzipped and is served over gzip. However on the local computer it is still unpacked and loaded on every page. Is this a performance issue? I've profiled the javascript with firebug profiler but did not see any issues. The problem/illusion I am facing is there are jquery libraries compressed in that file that are sometimes not used on the current page. For example jquery datatables is 200kb compressed and that is only loaded on 2 of my website pages. Another is jqplot and that is another 200kb. I now have 400kb of excess code that isn't executed on 80% of the pages. Should I leave everything in 1 file? Should I take out the jquery libraries and load only relevant JS on the current page?

• Finding shapes in 2D Array, then optimising

  - by assemblism

  I'm new so I can't do an image, but below is a diagram for a game I am working on, moving bricks into patterns, and I currently have my code checking for rotated instances of a "T" shape of any colour. The X and O blocks would be the same colour, and my last batch of code would find the "T" shape where the X's are, but what I wanted was more like the second diagram, with two "T"s Current result      Desired Result [X][O][O]                [1][1][1] [X][X][_]                [2][1][_] [X][O][_]                [2][2][_] [O][_][_]                [2][_][_] My code loops through x/y, marks blocks as used, rotates the shape, repeats, changes colour, repeats. I have started trying to fix this checking with great trepidation. The current idea is to: loop through the grid and make note of all pattern occurrences (NOT marking blocks as used), and putting these to an array loop through the grid again, this time noting which blocks are occupied by which patterns, and therefore which are occupied by multiple patterns. looping through the grid again, this time noting which patterns obstruct which patterns That much feels right... What do I do now? I think I would have to try various combinations of conflicting shapes, starting with those that obstruct the most other patterns first.How do I approach this one? use the rational that says I have 3 conflicting shapes occupying 8 blocks, and the shapes are 4 blocks each, therefore I can only have a maximum of two shapes. (I also intend to incorporate other shapes, and there will probably be score weighting which will need to be considered when going through the conflicting shapes, but that can be another day) I don't think it's a bin packing problem, but I'm not sure what to look for. Hope that makes sense, thanks for your help

• D3D9 Alpha Blending on the surfaces

  - by Indeera

  I have a surface (OffScreenPlain or RenderTarget with D3DFMT_A8R8G8B8) which I copy pixels (ARGB) to, from a third party function. Before pixel copying, Bits are accessed by LockRect. This surface is then StretchRect to the Backbuffer which is (D3DFMT_A8R8G8B8). Surface and Backbuffer are different dimensions. Filtering is set to D3DTEXF_NONE. Just after creating the d3d device I've set following RenderState settings D3DRS_ALPHABLENDENABLE -> TRUE D3DRS_BLENDOP -> D3DBLENDOP_ADD D3DRS_SRCBLEND -> D3DBLEND_SRCALPHA D3DRS_DESTBLEND -> D3DBLEND_INVSRCALPHA But I see no alpha blending happening. I've verified that alpha is specified in pixels. I've done a simple test by creating a vertex buffer and drawing a triangle (DrawPrimitive) which displays with alpha blending. In this test surface was StretchRect first and then DrawPrimitive, and the surface content displays without alpha blending and the triangle displays with alpha blending. What am I missing here? Thanks

• download/export emails from webmail

  - by misterjinx

  hello, I'm just switching my hosts and I want to move the emails from my accounts too. In order to have my current emails on the new host I want to download/export them and to import at the other host. In order to do this I use one of the webmail (squirrelmail, roundcube, horde) clients available on my current host. The problem is that except for roundcube, I don't see any download/export option available. And in roundcube I can only select one email at a time and download it as eml. My question is how do I export/download all the emails from one account and import them at the new host? I know this is possible because I remember doing this some time ago using squirrelmail, but I can't find anything related to this now. Thank you.

• Domain Transfer Protection - need advice

  - by Jack

  Hey, I am about to purchase a domain name for a bit of money. I do not personally know the person who I am purchasing the domain name from, we have only chatted via email. The proposed process for the transfer is: The owner of the domain lowest the domain name security and emails me the domain password, I request the transfer After the request, I transfer the money via PayPal When the money has been cleared the current domain name owner confirms the transfer via the link that he receives in that email I wait for it to be transferred. The domain is currently registered with DirectNIC - http://www.directnic.com/ Is this the best practice? Seeing I am paying a bit of money for this domain name, I am worried that after the money has been cleared that I won't see the domain name or hear from the current domain name owner again. Is there a 'domain governing body' which I can report to if this is the case? Is the proposed transfer process the best solution? Any advice would be awesome. Thanks! Jack

• How To Change Attachment Size in WorkItems in TFS 2010

  - by Ravi

  Recently, I came across an issue where I had to change the size limit for WorkItem Attachments in TFS 2010. I searched all around the internet only to find very little information around it which wasn’t clear honestly. So after breaking my head for sometime, I was successful in doing it. Here are my conclusions and the procedure to do it. 1. You DON’T 'have to' programmatically change it. You can do it directly from IIS webservices. 2. You CAN change it programmatically too, by making an entry into TFS Registry using a small piece of code. Let me show you how it is done from IIS. This is to change the size of attachment to your required value for workItems in TFS 2010 for each collection individually. You must be a TFS Admin to do this ( Login with setup account ) Browse to /WorkItemTracking/v1.0/ConfigurationSettingsService.asmx">/WorkItemTracking/v1.0/ConfigurationSettingsService.asmx">/WorkItemTracking/v1.0/ConfigurationSettingsService.asmx">http://localhost:8080/tfs/<YOUR-COLLECTION-NAME>/WorkItemTracking/v1.0/ConfigurationSettingsService.asmx You’ll see 3 asmx services – GetMaxAttachmentSize, GetWorkItemTrackingVersion and SetMaxAttachmentSize. 4. To know what is the current value of the maximum attachment size for a collection, click on the first service and you’ll the current existing value for this particular collection when you click on ‘invoke’ button. ( value is in bytes ) 5. Now click on the ‘SetMaxAttachmentSize’ webservice and fill in the value of your choice. 6. Reset IIS ( not required honestly, but I did it, just to be sure ) 7. Now try attaching a file greater than the size you’ve set. It’ll fail successfully   Below is the error which you’d see in such scenarios. Let me know if you see any issues & I’ll be happy to help..!

• Better way to set up samba bridge?

  - by Adam Butler

  I have an old ubuntu laptop hooked up to between my wireless network and a wired media player box. I had previously shared my wireless network connection so the media player had internet access (ie. via nat) because it was a different subnet it could not access the file shares on the wireless network. To get around this I mounted the drives from the wireless network on the laptop and re-shared them with samba. This worked ok but had some drawbacks, it seemed slow and if network computers were turned off when the laptop rebooted I had to manually mount the shares. I've just re-installed with the latest ubuntu and was wondering if there is a better way to do this. Is there some way to bridge so the media player appears to be on the wireless network? Would this give better performance? Any other options? I'm also thinking there might be some samba options that could buffer files?

• Finding header files

  - by rwallace

  A C or C++ compiler looks for header files using a strict set of rules: relative to the directory of the including file (if "" was used), then along the specified and default include paths, fail if still not found. An ancillary tool such as a code analyzer (which I'm currently working on) has different requirements: it may for a number of reasons not have the benefit of the setup performed by a complex build process, and have to make the best of what it is given. In other words, it may find a header file not present in the include paths it knows, and have to take its best shot at finding the file itself. I'm currently thinking of using the following algorithm: Start in the directory of the including file. Is the header file found in the current directory or any subdirectory thereof? If so, done. If we are at the root directory, the file doesn't seem to be present on this machine, so skip it. Otherwise move to the parent of the current directory and go to step 2. Is this the best algorithm to use? In particular, does anyone know of any case where a different algorithm would work better?

• Java EE @ Devoxx UK

  - by delabassee

  Devoxx UK is taking place next week (12th and 13th June) in London. As with any Devoxx conference, this UK edition will have a nice mix of content, an impressive list of speakers and obviously Java EE will be well will covered too:  Apache TomEE, Java EE Web Profile and more on Tomcat (David Blevins) Myths, Tales and Voodoo - About Java EE and Testing (Adam Bien) 50 new features of Java EE 7 (Antonio Goncalves & Arun Gupta) Java EE 7 Hands-on Lab (Arun Gupta) In addition, there will be 2 BoF related to Java EE on Thursday evening, the first BoF will be about the Java EE platform and the second one will be about the Java EE Reference Implementation, i.e. GlassFish. I will participate in the Java EE Community BoF where will discuss Java EE general but with all recent activities, I suspect that a large portion of the BoF will spent on discussing the current plans for Java EE 8.  Right after and in the same room, I will join Steve Millidge of C2B2 for the GlassFish is here to stay! BoF. The goal is to discuss on GlassFish, the current status, the plans for the next release, how the community can contributes, etc. It should be mentioned that attending those BoFs is completely free, just make sure to register here.  So if you are in London next week, mind the Geek and see you at Devoxx UK!

• Delaying a Foreach loop half a second

  - by Sigh-AniDe

  I have created a game that has a ghost that mimics the movement of the player after 10 seconds. The movements are stored in a list and i use a foreach loop to go through the commands. The ghost mimics the movements but it does the movements way too fast, in split second from spawn time it catches up to my current movement. How do i slow down the foreach so that it only does a command every half a second? I don't know how else to do it. Please help this is what i tried : The foreach runs inside the update method DateTime dt = DateTime.Now; foreach ( string commandDirection in ghostMovements ) { int mapX = ( int )( ghostPostition.X / scalingFactor ); int mapY = ( int )( ghostPostition.Y / scalingFactor ); // If the dt is the same as current time if ( dt == DateTime.Now ) { if ( commandDirection == "left" ) { switch ( ghostDirection ) { case ghostFacingUp: angle = 1.6f; ghostDirection = ghostFacingRight; Program.form.direction = ""; dt.AddMilliseconds( 500 );// add half a second to dt break; case ghostFacingRight: angle = 3.15f; ghostDirection = ghostFacingDown; Program.form.direction = ""; dt.AddMilliseconds( 500 ); break; case ghostFacingDown: angle = -1.6f; ghostDirection = ghostFacingLeft; Program.form.direction = ""; dt.AddMilliseconds( 500 ); break; case ghostFacingLeft: angle = 0.0f; ghostDirection = ghostFacingUp; Program.form.direction = ""; dt.AddMilliseconds( 500 ); break; } } } }

• How do you structure your shared code so that it is "re-findable" for new developers?

  - by awmckinley

  I started working at my current job about 8 months ago, and its been one of the best experiences I've had as a young programmer. It's a small company, and both my co-developers are brilliant guys. One of the practices that they both have been encouraging is lots of code-reuse. Our code base is mainly C#, and we're using a centralized revision control system. The way the repository is currently structured, there is a single folder in which all shared class libraries are placed (along with unit tests for each library), and our revision control system allows for sharing or linking those libraries out to other projects. What I'm trying to understand at this point is how the current structure of the folder can be made more conducive for finding those libraries again. I've talked to the other developers about this, and they agree that it's gotten a little messy. I find that I am sometimes "reinventing the wheel" because I didn't realize that there was an existing piece of code that solved a particular problem. The issue is complicated further by the fact that we're sharing some code between ASP.NET MVC2, WinForms, and Windows CE projects, and sharing code between applications built against multiple versions of .NET. How do other people approach this? Is the answer in naming the libraries in a certain way or is it preferable to invest in some code-search software? Is the answer in doc comments? Should we be sharing libraries at all or should we simply branch the class libraries for re-use? Thanks for any and all help!

• Finishing an iteration early

  - by f1dave

  I'd like some input on this on those working with agile methodologies... A current project is finding that development on our planned user stories is finishing some time before the end of the iteration, and that the testing effort and business acceptance is what's actually dragging us out longer towards the end. This means that the devs in question have spare time, and they're essentially going out to the iteration+1 backlog and starting work on cards there before our current iteration cards are 'done'. As iteration manager, I want to put a stop to this - I want a more team-orientated approach where the group takes ownership of getting all the cards done, as opposed to "Well, dev's done so what do I dev next?" The problem I face is convincing the team of this. On one hand, I understand why the devs don't want to test the code they've written (there are unit tests they write of course, but the manual testing to be done could be influenced by their bias). The team sees working ahead as making our next iterations easier, because a lot of the work is done before we start. I see this as screwing with the whole system of planning/actuals - but it's difficult to convince the team as to why this matters. What advice can you guys and girls give? How do we stop devs reaching ahead? What should they be doing instead? How much of a problem is this in the scheme of things, if things are still getting done?

• how to do partial updates in OpenGL?

  - by Will

  It is general wisdom that you redraw the entire viewport on each frame. I would like to use partial updates; what are the various ways can do that, and what are their pros, cons and relative performance? (Using textures, FBOs, the accumulator buffer, any kind of scissors that can affect swapbuffers etc?) A scenario: a scene with a fair few thousand visible trees; although the textures are mipmapped and they are drawn via VBOs roughly front-to-back with so on, its still a lot of polys. Would streaming a single screen-sized texture be better than throwing them at the screen every frame? You'd have to redraw and recapture them only on camera movement or as often as your wind model updates or whatever, which need not be every frame.
