• How do I get the Apple Wireless Keyboard Working in 10.10?

  - by Jamie

  So I've gone and bought a Magic Mouse and Apple Wireless Non-Numeric Keyboard. The magic mouse worked out-of-the-box almost perfectly, except for the forward/back gesture which still isn't functioning, whereas the keyboard didn't. It has constant trouble with the bluetooth connection. Only the 7, 8 and 9 buttons and volume media keys correspond…

• creating a 3d plane using Frank Luna's technique

  - by numerical25

  I am creating a 3d plane that lays on the x and z axis. and has hills that extend on the y axis. bulk of the code looks like this float PeaksAndValleys::getHeight(float x, float z)const { return 0.3f*( z*sinf(0.1f*x) + x*cosf(0.1f*z) ); } void PeaksAndValleys::init(ID3D10Device* device, DWORD m, DWORD n, float dx) { md3dDevice =…

• Is this a File Header / Magic Number?

  - by Hammer Bro.

  I've got 120,000 files (way more, actually; this is just an arbitrary subset) of an unknown type. Linux file does not identify them (not that they're necessarily Linux files), nor do any other methods I've tried. There are only two hints about them that I currently have. One is that I suspect some compression is employed -- I have…

• Windows 7 - "Magic" frequent folder

  - by TheAdamGaskins

  Every week, I export an mp3 file from audacity into a folder with that day's date (e.g. this past sunday I exported the file to a folder named 20130609). Then I close everything and that's it for a while. Then, I come back a few hours later to upload the file to ftp. I usually have some folders open, so to open a new one, I right…

• Partition Magic 8 made TrueCrypt partition invisible

  - by gmancoda

  Partition Magic 8 took a dump on my TrueCrypt partition... and I let it happen! And now I am left with cleaning up the mess. In short, my encrypted partition is now invisible. TestDisk analysis says of the disk containing the encrypted partition: "Space conflict between the following two partitions". From the googling and…

• How to rotate a set of points on z = 0 plane in 3-D, preserving pairwise distances?

  - by cagirici

  I have a set of points double n[] on the plane z = 0. And I have another set of points double[] m on the plane ax + by + cz + d = 0. Length of n is equal to length of m. Also, euclidean distance between n[i] and n[j] is equal to euclidean distance between m[i] and m[j]. I want to rotate n[] in 3-D, such that for all i,…

• Write magic bytes to the stack to monitor its usage

  - by tkarls

  I have a problem on an embedded device that I think might be related to a stack overflow. In order to test this I was planning to fill the stack with magic bytes and then periodically check if the stack has overflowed by examining how much of my magic bytes that are left intact. But I can't get the routine for marking…

• Incorrect results for frustum cull

  - by DeadMG

  Previously, I had a problem with my frustum culling producing too optimistic results- that is, including many objects that were not in the view volume. Now I have refactored that code and produced a cull that should be accurate to the actual frustum, instead of an axis-aligned box approximation. The…

• Any "Magic Tricks" For Getting Data Back After Windows 7 Install

  - by user163757

  My old man installed Windows 7 without making a proper backup, and now realizes he left behind some important data. He did a true "clean install", so there is no Windows.old folder in the root directory. However, I believe the format performed on the hard drive was only a quick format, so I am…

• Looking for a regular expression to identify hard coded magic numbers in source code

  - by Brian

  A frequent issue in code reviews is whether a numeric value should be hard-coded in the code or not. Does anyone know of a nice regular expression that can catch 'magic numbers' in code like: int overDue = 30; Money fee = new Money(5.25D); without also getting a ton of false positives like…

• signed angle between two 3d vectors with same origin within the same plane? recipe?

  - by Advanced Customer

  Was looking through the web for an answer but it seems like there is no clear recipe for it. What I need is a signed angle of rotation between two vectors Va and Vb lying within the same 3D plane and having the same origin knowing that: the plane contatining both vectors is an arbitrary…

• Is -1 a magic number? An anti-pattern? A code smell? Quotes and guidelines from authorities

  - by polygenelubricants

  I've seen -1 used in various APIs, most commonly when searching into a "collection" with zero-based indices, usually to indicate the "not found" index. This "works" because -1 is never a legal index to begin with. It seems that any negative number should work, but I think -1 is almost…

• How do I draw a 2d plane and rotate camara (To be a board) in a 3d XNA game?

  I am trying to create a simple board game, but the 3d part of this is really killing me. From what I can gather I have created a plane, but it never moves even though I turn the camara, but that partially makes sense as I only turn the camara with a 3d…
