• HTG Explains: What Is Open-Source Software and Why You Should Care

  - by Chris Hoffman

  Geeks often describe programs as being “open source” or “free software.” If you’re wondering exactly what these terms mean and why they matter, read on. (No, “free software” doesn’t just mean that you can download it for free.) Whether a program is open-source or not doesn’t just matter to developers, it ultimately matters for users, too. Open-source software licenses give users freedoms they would not otherwise have.

• HTG Explains: Why You Only Have to Wipe a Disk Once to Erase It

  - by Chris Hoffman

  You’ve probably heard that you need to overwrite a drive multiple times to make the data unrecoverable. Many disk-wiping utilities offer multiple-pass wipes. This is an urban legend – you only need to wipe a drive once. Wiping refers to overwriting a drive with all 0’s, all 1’s, or random data. It’s important to wipe a drive once before disposing of it to make your data unrecoverable, but additional wipes offer a false sense of security.

  I can log into WHMCS & can access everything I should be able to access, but if i try to click View PDF Invoice, the following error will occur, Fatal error: Out of memory (allocated 67633152) (tried to allocate 76 bytes) in /home/xxxx/public_html/whmcs/includes/classes/class.tcpdf.php on line 8419 I have already set the allocated Memory limit to 256MB, but the error still occurs.

• Smooth vector based jump

  - by Esa

  I started working on Wolfire's mathematics tutorials. I got the jumping working well using a step by step system, where you press a button and the cube moves to the next point on the jumping curve. Then I tried making the jumping happen during a set time period e.g the jump starts and lands within 1.5 seconds. I tried the same system I used for the step by step implementation, but it happens instantly. After some googling I found that Time.deltatime should be used, but I could not figure how. Below is my current jumping code, which makes the jump happen instantly. while (transform.position.y > 0) { modifiedJumperVelocity -= jumperDrag; transform.position += new Vector3(modifiedJumperVelocity.x, modifiedJumperVelocity.y, 0); } Where modifiedJumperVelocity is starting vector minus the jumper drag. JumperDrag is the value that is substracted from the modifiedJumperVelocity during each step of the jump. Below is an image of the jumping curve:

• Who owns code if its written by one person with another person directing [on hold]

  - by user136226

  I have an Issue that I need some info on. Basically what Im looking to find out is if I create software,and someone else gives me direction on what they want the software to look like,e.g. an image here,this font of text and it must behave in a certain way. Also some of the code was not developed on my computer and there is no official agreement in place. Not looking to screw anyone over here but need to protect myself if things go sour. Do I own the software or is it jointly owned? Thanks

• Lwjgl or opengl double pixels

  - by Philippe Paré

  I'm working in java with LWJGL and trying to double all my pixels. I'm trying to draw in an area of 800x450 and then stretch all the frame image to the complete 1600x900 pixels without them getting blured. I can't figure out how to do that in java, everything I find is in c++... A hint would be great! Thanks a lot. EDIT : I've tried drawing to a texture created in opengl by setting it to the framebuffer, but I can't find a way to use glGenTextures() in java... so this is not working... also I though about using a shader but I would not be able to draw only in the smaller region...

• DX11 - Weird shader behavior with and without branching

  - by Martin Perry

  I have found problem in my shader code, which I dont´t know how to solve. I want to rewrite this code without "ifs" tmp = evaluate and result is 0 or 1 (nothing else) if (tmp == 1) val = X1; if (tmp == 0) val = X2; I rewite it this way, but this piece of code doesn ´t word correctly tmp = evaluate and result is 0 or 1 (nothing else) val = tmp * X1 val = !tmp * X2 However if I change it to: tmp = evaluate and result is 0 or 1 (nothing else) val = tmp * X1 if (!tmp) val = !tmp * X2 It works fine... but it is useless because of "if", which need to be eliminated I honestly don´t understand it Posted Image . I tried compilation with NO and FULL optimalization, result is same

• How to spawn a character at certain point and walk to a set point

  - by Robert H.

  I am making a game where I have a background image of a neighborhood. Each location has a different number of customers that are generated to walk on sidewalks. They all walk to a specific location (like a stand or cart that sells stuff), after they get to location I want them to interact with the cart. However, if another customer is already in a sale interaction then the others get in line in order of arrival. After the transaction the customers walk off screen. Any information on how I can do this and what game engine would be needed? Any one have any idea where I should go for this. I already have my game done up through Eclipse/Java without any game engine.

• 2D Grid based game - how should I draw grid lines?

  - by Adam K Dean

  I'm playing around with a 2D grid based game idea, and I am using sprites for the grid cells. Let's say there is a 10 x 10 grid and each cell is 48x48, which will have sprites drawn there. That is fine. But in design mode, I'd like to have a grid overlay the screen. I can do this either with sprites (2x600 pixel image etc) or with primitives, but which is best? Should I really be switching between sprites and 3d/2d rendering? Like so: Thanks!

• What technologies are used for Game development now days?

  - by Monika Michael

  Whenever I ask a question about game development in an online forum I always get suggestions like learning line drawing algorithms, bit level image manipulation and video decompression etc. However looking at games like God of War 3, I find it hard to believe that these games could be developed using such low level techniques. The sheer awesomeness of such games defy any comprehensible(for me) programming methodology. Besides the gaming hardware is really a monster now days. So it stands to reason that the developers would work at a higher level of abstraction. What is the latest development methodology in the gaming industry? How is it that a team of 30-35 developers (of which most is management and marketing fluff) able to make such mind boggling games?

• application custom stock icons not working in ubuntu unity top panel menu (aka appmenu) ("Menus Have Icons" ON)

  - by giuspen

  I recently noticed that in ubuntu unity the top menu of my apps does not show the (custom) icons I added to the gtk stock, but only the basic gtk stock icons. This happens only since the top menu is displayed in the unity top panel (appmenu) and not in the application window. In place of the correct custom icons I see "gtk-missing-image". On my apps toolbars and other menus those icons are displayed properly, the problem is only with the top menu. This happens either with pygtk2 (e.g. http://www.giuspen.com/cherrytree/) and gobject introspection (e.g. http://www.giuspen.com/nautilus-pyextensions/). I use gtk ui manager after integrating the stock icons this way: factory = gtk.IconFactory() pixbuf = gtk.gdk.pixbuf_new_from_file(filepath) iconset = gtk.IconSet(pixbuf) factory.add(stock_name, iconset) factory.add_default() If anybody solved this problem please help. Cheers, Giuseppe.

• How to retrieve packages from an ISO?

  - by Santosh Kumar

  I have an ISO image of BackTrack and I want to try it, but I don't want to mess up my bootloader with installing 2 Linuxes and a Windows. As BackTrack is Debian based I want to use its packages in my current Ubuntu. I tried mounting the ISO with Archive Mounter but whole operating system seems to be in casper/filesystem.squashfs file. I have seen this answer but none of those methods work, because I can't find any pool directory. The only file I suspect is filesystem.squashfs which is 3.3 GB in size. Please help me install tools from BackTrack's ISO.

• XNA Transparency depending on drawing order?

  - by DarthRoman

  I am drawing two 3D objects, both of them can fade from opaque to transparent independently, and they can intersect between them (so you cannot say when one of them is before the other one). Look at the image for a better understanding (one of the object is a terrain and the other one an area): Now, if I apply transparency to both of them, and draw the terrain before the area, the terrain is not transparent respecting to the area, but the area is: And finally, if I draw the area before the terrain, then the area is not transparent respecting of the terrain: QUESTION: How can I make all the objects transparent to the rest of objects without depending on the drawing order?

• My frustum culling is culling from the wrong point

  - by Xbetas

  I'm having problems with my frustum being in the wrong origin. It follows the rotation of my camera but not the position. In my camera class I'm generating a view-matrix: void Camera::Update() { UpdateViewMatrix(); glMatrixMode(GL_MODELVIEW); //glLoadIdentity(); glLoadMatrixf(GetViewMatrix().m); } Then extracting the planes using the projection matrix and modelview matrix: void UpdateFrustum() { Matrix4x4 projection, model, clip; glGetFloatv(GL_PROJECTION_MATRIX, projection.m); glGetFloatv(GL_MODELVIEW_MATRIX, model.m); clip = model * projection; m_Planes[RIGHT][0] = clip.m[ 3] - clip.m[ 0]; m_Planes[RIGHT][1] = clip.m[ 7] - clip.m[ 4]; m_Planes[RIGHT][2] = clip.m[11] - clip.m[ 8]; m_Planes[RIGHT][3] = clip.m[15] - clip.m[12]; NormalizePlane(RIGHT); m_Planes[LEFT][0] = clip.m[ 3] + clip.m[ 0]; m_Planes[LEFT][1] = clip.m[ 7] + clip.m[ 4]; m_Planes[LEFT][2] = clip.m[11] + clip.m[ 8]; m_Planes[LEFT][3] = clip.m[15] + clip.m[12]; NormalizePlane(LEFT); m_Planes[BOTTOM][0] = clip.m[ 3] + clip.m[ 1]; m_Planes[BOTTOM][1] = clip.m[ 7] + clip.m[ 5]; m_Planes[BOTTOM][2] = clip.m[11] + clip.m[ 9]; m_Planes[BOTTOM][3] = clip.m[15] + clip.m[13]; NormalizePlane(BOTTOM); m_Planes[TOP][0] = clip.m[ 3] - clip.m[ 1]; m_Planes[TOP][1] = clip.m[ 7] - clip.m[ 5]; m_Planes[TOP][2] = clip.m[11] - clip.m[ 9]; m_Planes[TOP][3] = clip.m[15] - clip.m[13]; NormalizePlane(TOP); m_Planes[NEAR][0] = clip.m[ 3] + clip.m[ 2]; m_Planes[NEAR][1] = clip.m[ 7] + clip.m[ 6]; m_Planes[NEAR][2] = clip.m[11] + clip.m[10]; m_Planes[NEAR][3] = clip.m[15] + clip.m[14]; NormalizePlane(NEAR); m_Planes[FAR][0] = clip.m[ 3] - clip.m[ 2]; m_Planes[FAR][1] = clip.m[ 7] - clip.m[ 6]; m_Planes[FAR][2] = clip.m[11] - clip.m[10]; m_Planes[FAR][3] = clip.m[15] - clip.m[14]; NormalizePlane(FAR); } void NormalizePlane(int side) { float length = 1.0/(float)sqrt(m_Planes[side][0] * m_Planes[side][0] + m_Planes[side][1] * m_Planes[side][1] + m_Planes[side][2] * m_Planes[side][2]); m_Planes[side][0] /= length; m_Planes[side][1] /= length; m_Planes[side][2] /= length; m_Planes[side][3] /= length; } And check against it with: bool PointInFrustum(float x, float y, float z) { for(int i = 0; i < 6; i++) { if( m_Planes[i][0] * x + m_Planes[i][1] * y + m_Planes[i][2] * z + m_Planes[i][3] <= 0 ) return false; } return true; } Then i render using: camera->Update(); UpdateFrustum(); int numCulled = 0; for(int i = 0; i < (int)meshes.size(); i++) { if(!PointInFrustum(meshCenter.x, meshCenter.y, meshCenter.z)) { meshes[i]->SetDraw(false); numCulled++; } else meshes[i]->SetDraw(true); } What am i doing wrong?

• Which of VLC's dependencies causes sound device detection?

  - by Raphael

  I am setting up a headless music server based on the minimal Ubuntu image. After having installed the packages openssh-server,pulseaudio, libmad0,flac,liboff0,libid3tag0,libvorbis0a,ffmpeg, mpd,mpc,mpdscribble, paman,paprefs,pavumeter neither my internal soundcard nor the external DAC where detected by pulseaudio, that is pactl list did only list the dummy devices. Several reboots did not change that. The hardware devices are detected properly: ~$ lsusb | grep Texas Bus 002 Device 002: ID 08bb:2706 Texas Instruments Japan ~$ lspci | grep Audio 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Following a hunch, I installed vlc with all dependencies. After a reboot, both devices are detected! ~$ pactl list | grep "Sink: alsa_output" Monitor of Sink: alsa_output.pci-0000_00_1b.0.analog-stereo Monitor of Sink: alsa_output.usb-Burr-Brown_from_TI_USB_Audio_DAC-00-DAC.analog-stereo Now I would like to remove VLC again but keep the devices. The question is: which of the many dependencies of VLC enables proper device detection? And why on earth is it not a dependency of pulseaudio?

• USB-live does not save files between sessions

  - by Mads Skjern

  I created a USB-stick with Ubuntu, using the recommended tool "Startup Disk Creator" and the image for Ubuntu 13.10. The very simple interface looks like this: There can't be much to misunderstand in this GUI. I have chosen to create a USB stick with a live version of Ubuntu, which will save files and settings from session to session, on the USB drive, right? Well, it just doesn't save anything. I go in, create a file on Desktop, restart and it's gone. I did the whole procedure three times, i.e. first creating the USB, then testing if I could save. Have I misunderstood something?

• How to Banish Duplicate Photos with VisiPic

  - by Jason Fitzpatrick

  You meant well, you intended to be a good file custodian, but somewhere along the way things got out of hand and you’ve got duplicate photos galore. Don’t be afraid to delete them and lose important photos, read on as we show you how to clean safely. Deleting duplicate files, especially important ones like personal photos, makes a lot of people quite anxious (and rightfully so). Nobody wants to be the one to realize that they deleted all the photos of their child’s first birthday party during a hard drive purge gone wrong. In this tutorial we’re going to show you how to go beyond the limited reach of  tools which simply compare file names and file sizes. Instead we’ll be using a program that combines that kind of comparison with actual image analysis to help you weed out not just perfect 1:1 file duplicates but also those piles of resized for email images, cropped images, and other modified images that might be cluttering up your hard drive.
