  • Just installed Ubuntu 12.04 - integrated speakers aren't working but headphones are

    - by Mat Elkan
    I've just installed Ubuntu 12.04 alongside Windows Vista. There were no previous versions of Ubuntu installed. My computer is a Sony Vaio all in one, with integrated sound card and speakers. I can't get any sound coming from the speakers, but if I plug headphones into the jack on the side of the computer and select "headphones" under "sound" in "system settings" I can get sound through them. I have been searching all day trying to find a fix but haven't had any luck. Any advice would be greatly appreciated. Thanks! Mat :-)

  • How to move the camera sideways in libgdx

    - by Bubblewrap
    I want to move the camera sideways (strafe/truck), now i had the following in mind, but it doesn't look like there are standard methods to achieve this in libgdx. If i want to move the camera sideways by x, i think i need to do the following: Create a Matrix4 mat Determine the orthogonal vector v between camera.direction and camera.up translate mat by v*x multiply camera.position by mat Will this approach do what i think it does, and is it a good way to do it? And how can i do this in libgdx? I get "stuck" at step 2, as in, i have not found any standard method in libgdx to calculate an orthogonal vector. EDIT: I think i can use camera.direction.crs(camera.up) to find v. Guess i can now try this approach tonight and see if it works.

  • How to Make Your Computer Press a Key Every X Seconds

    - by The Geek
    Have you ever needed to press a key every couple of seconds, or every few minutes? Perhaps you’re playing a video game and you’re waiting for an item, or you’ve got some other reason. Either way, here’s how to make your PC do it automatically. You’ll need to start by downloading and installing AutoHotkey, which is a simple scripting language that allows you to create easy scripts. Once you do that, right-click anywhere and choose New –> AutoHotkey Script. Once you’ve done that, paste the following into the script: #PersistentSetTimer, PressTheKey, 1800000Return HTG Explains: How Hackers Take Over Web Sites with SQL Injection / DDoS Use Your Android Phone to Comparison Shop: 4 Scanner Apps Reviewed How to Run Android Apps on Your Desktop the Easy Way

  • Byte Size Tips: How to Disable the Useless Dashboard on Mac OS X

    - by The Geek
    After getting my new MacBook Air with the awesome battery life, I decided to give OS X a spin for a while to see how I liked it. About 34 seconds later, I encountered my first irritation: The stupid Dashboard feature is just completely useless. Here’s how to disable it. Note: overall, Mac OS X is a really great operating system. It’s just this one feature that makes no sense. Simply Remove Dashboard from Spaces

  • Byte Size Tips: How to Change Your Computer Name on Mac OS X

    - by The Geek
    When you’re sharing stuff back and forth between your computers, the names of those computers actually start to matter — in my case, I upgraded to a new MacBook Air because my old one has a dead screen and is out of warranty, so I made it into a desktop with an external monitor. That’s when I got an error that my two Macs had the same name. Oops! Luckily it’s an extremely easy fix. Just open up System Preferences, go to Sharing, and change the computer name. Done! You can also change it from the Terminal using this command, though obviously it’s much simpler to just change it under Sharing.

  • How to Create a Minimize All Windows (Win + M) Hotkey for Mac OS X

    - by The Geek
    Windows users have been able to minimize every window on their desktop ever since keyboards with the Win key started showing up — just tap WIN + M on your keyboard, and every window is minimized. For Mac OS X, it’s not quite as simple. You can, of course, use the CMD + OPT + H + M shortcut key combination to hide most windows… but that’s a lot of keys to hit at once, and it doesn’t always minimize everything in my experience. So like everything else I wanted from Windows, it was time to figure out how to get it on OS X as well. This method uses QuickSilver to provide the shortcut key trigger — if there’s a better way to do that, please let us know. Luckily OS X includes a nice scripting platform, and we can use the following script from a helpful person over at SuperUser to make this all happen. tell application "Finder" to activate tell application "System Events" tell application process "Finder" tell menu bar 1 click menu item "Hide Others" of menu of menu bar item "Finder" click menu item "Minimize All" of menu of menu bar item "Window" end tell end tell end tell Open up a new AppleScript Editor window and paste in the script from above. Then go to File and Save.

  • 2D OBB collision detection, resolving collisions?

    - by Milo
    I currently use OBBs and I have a vehicle that is a rigid body and some buildings. Here is my update() private void update() { camera.setPosition((vehicle.getPosition().x * camera.getScale()) - ((getWidth() ) / 2.0f), (vehicle.getPosition().y * camera.getScale()) - ((getHeight() ) / 2.0f)); //camera.move(input.getAnalogStick().getStickValueX() * 15.0f, input.getAnalogStick().getStickValueY() * 15.0f); if(input.isPressed(ControlButton.BUTTON_GAS)) { vehicle.setThrottle(1.0f, false); } if(input.isPressed(ControlButton.BUTTON_BRAKE)) { vehicle.setBrakes(1.0f); } vehicle.setSteering(input.getAnalogStick().getStickValueX()); vehicle.update(16.6666f / 1000.0f); ArrayList<Building> buildings = city.getBuildings(); for(Building b : buildings) { if(vehicle.getRect().overlaps(b.getRect())) { vehicle.update(-17.0f / 1000.0f); break; } } } The collision detection works well. What doesn't is how they are dealt with. My goal is simple. If the vehicle hits a building, it should stop, and never go into the building. When I apply negative torque to reverse the car should not feel buggy and move away from the building. I don't want this to look buggy. This is my rigid body class: class RigidBody extends Entity { //linear private Vector2D velocity = new Vector2D(); private Vector2D forces = new Vector2D(); private float mass; //angular private float angularVelocity; private float torque; private float inertia; //graphical private Vector2D halfSize = new Vector2D(); private Bitmap image; public RigidBody() { //set these defaults so we don't get divide by zeros mass = 1.0f; inertia = 1.0f; } //intialize out parameters public void initialize(Vector2D halfSize, float mass, Bitmap bitmap) { //store physical parameters this.halfSize = halfSize; this.mass = mass; image = bitmap; inertia = (1.0f / 20.0f) * (halfSize.x * halfSize.x) * (halfSize.y * halfSize.y) * mass; RectF rect = new RectF(); float scalar = 10.0f; rect.left = (int)-halfSize.x * scalar; rect.top = (int)-halfSize.y * scalar; rect.right = rect.left + (int)(halfSize.x * 2.0f * scalar); rect.bottom = rect.top + (int)(halfSize.y * 2.0f * scalar); setRect(rect); } public void setLocation(Vector2D position, float angle) { getRect().set(position, getWidth(), getHeight(), angle); } public Vector2D getPosition() { return getRect().getCenter(); } @Override public void update(float timeStep) { //integrate physics //linear Vector2D acceleration = Vector2D.scalarDivide(forces, mass); velocity = Vector2D.add(velocity, Vector2D.scalarMultiply(acceleration, timeStep)); Vector2D c = getRect().getCenter(); c = Vector2D.add(getRect().getCenter(), Vector2D.scalarMultiply(velocity , timeStep)); setCenter(c.x, c.y); forces = new Vector2D(0,0); //clear forces //angular float angAcc = torque / inertia; angularVelocity += angAcc * timeStep; setAngle(getAngle() + angularVelocity * timeStep); torque = 0; //clear torque } //take a relative Vector2D and make it a world Vector2D public Vector2D relativeToWorld(Vector2D relative) { Matrix mat = new Matrix(); float[] Vector2Ds = new float[2]; Vector2Ds[0] = relative.x; Vector2Ds[1] = relative.y; mat.postRotate(JMath.radToDeg(getAngle())); mat.mapVectors(Vector2Ds); return new Vector2D(Vector2Ds[0], Vector2Ds[1]); } //take a world Vector2D and make it a relative Vector2D public Vector2D worldToRelative(Vector2D world) { Matrix mat = new Matrix(); float[] Vectors = new float[2]; Vectors[0] = world.x; Vectors[1] = world.y; mat.postRotate(JMath.radToDeg(-getAngle())); mat.mapVectors(Vectors); return new Vector2D(Vectors[0], Vectors[1]); } //velocity of a point on body public Vector2D pointVelocity(Vector2D worldOffset) { Vector2D tangent = new Vector2D(-worldOffset.y, worldOffset.x); return Vector2D.add( Vector2D.scalarMultiply(tangent, angularVelocity) , velocity); } public void applyForce(Vector2D worldForce, Vector2D worldOffset) { //add linear force forces = Vector2D.add(forces ,worldForce); //add associated torque torque += Vector2D.cross(worldOffset, worldForce); } @Override public void draw( GraphicsContext c) { c.drawRotatedScaledBitmap(image, getPosition().x, getPosition().y, getWidth(), getHeight(), getAngle()); } } Essentially, when any rigid body hits a building it should exhibit the same behavior. How is collision solving usually done? Thanks

  • Byte Size Tips: How to Stop OS X from Changing the Display Brightness Automatically

    - by The Geek
    After getting a new MacBook Air and deciding to try out OS X for a while, I started wondering why the battery would suddenly start dying really fast, but only when I was sitting at the kitchen table. That’s when I noticed the display brightness kept changing on its own… and realized the problem. OS X, just like your phone, and any modern device, tries to figure out the brightness of the room you’re in, and adjust the brightness of the screen. If you are over in Windows, it’s called “Adaptive” brightness, while your phone will just call it “Auto”. While this technology is great in theory, I don’t really need max brightness all the time, and I like to control it manually to make sure I’m getting the best battery life. Open up System Preferences, head to Displays. Then uncheck the Automatically adjust brightness setting.

  • Byte Size Tips: How to Show Google / Gmail Contacts in the OS X Contacts App

    - by The Geek
    The Contacts app on OS X isn’t very interesting, but if you can use it to display your Gmail contacts, it’ll get a little bit better. Luckily it’s pretty easy to add your Google / Gmail contacts, but you’ll have to click the mouse a few times and maybe poke at the old keyboard once or twice to type in your email address and password. It’s worth noting that if you set up Gmail in the Mail app you shouldn’t have to do this. Since we prefer Gmail in a browser, that’s why we’re writing this. Or just because we’re procrastinating the book editing that we’re supposed to be doing. Don’t judge. Start by opening the Preferences for the Contacts app by heading up to the Menu bar. Go to Accounts and then click the + sign to add a new one. Choose CardDAV for the account type, use your Gmail username and password, and put google.com as the server address. If you are using two-factor authentication, you’ll need to create a specific password for this account.

  • Make Your Own Windows 8 Start Button with Zero Memory Usage

    - by The Geek
    After using Windows 8 for a while, I’ve come to the conclusion that removing the Start button from the Taskbar was a huge mistake. Here’s how to make your own “Start” button that brings up the Metro Start screen—but doesn’t waste any memory at all. What we’ll be doing is pretty simple—create a script that simulates pressing the Windows key button, make it into an executable, assign an icon, and pin it to the taskbar so that it sorta looks like the Start button, and works the same way. Since nothing is running, no RAM is wasted.

  • How to Use Vim-Style Keyboard Shortcuts for OS X Tab Navigation

    - by The Geek
    After switching to OS X when I got a new MacBook Air, one of the first things I needed to duplicate was my extremely customized AutoHotkey setup — the most important of which is using the J and K keys to navigate throughout tabbed windows easily. Yeah, I’m a Vim user. I’ve never been a fan of having to use CTRL + TAB to switch from one tab to the next — to start with, you have to move your hands from the home row, and it’s awkward, and why should I have to do that just because somebody decided that keyboard shortcut before tabs became popular? If you think about it, if tabbed browsers were popular back when keyboard shortcuts were being invented, they would have definitely reserved some of the good shortcuts for switching tabs. On Windows, I’ve always used an AutoHotkey script to make things the way I wanted it:  ALT + J and ALT + K for selecting previous and next tabs. Once you get used to it, it’s extremely awesome, and so much faster than using CTRL + TAB. Of course, I also hacked CTRL + T and CTRL + W into ALT + T and ALT + W so I could open new tabs and close them without moving my hands from the home row. Over on OS X, it turns out that it’s incredibly simple and easy to use CMD + J and CMD + K for next/previous tab navigation, and it works in most applications that support tabs, like Terminal, Safari, or Google Chrome.

  • Reliability Monitor is the Best Windows Troubleshooting Tool You Aren’t Using

    - by The Geek
    When it comes to hidden gems in Windows, nothing beats the Reliability monitor tool, hidden behind a link inside of another tool that you don’t use either. Why Microsoft doesn’t shine more light on this really useful troubleshooting tool, we’ll never know. Reliability Monitor tracks the history of your computer — any time an application crashes, hangs, or Windows gives you a blue screen of death. It also tracks other important events, like when software is installed, or Windows Updates loads a new patch. It’s an extremely useful tool. And yes, it’s in Windows 7 and 8… and even 8.1. It might be in Vista, but who uses that anymore?

  • Myths: Does Deleting the Cache Actually Speed Up Your PC?

    - by The Geek
    Every time you ask somebody with a reasonable level of tech skills what you should do to speed up your PC, they start jabbering on about running ccleaner and clearing the cache. But does the act of clearing a cache really speed things up? Nope. Most people assume that all temporary files are just clutter created by lousy applications, but that isn’t actually the truth. Cache files are created by apps to store commonly used information so it doesn’t have to be generated or downloaded again.
