  • Memory Glutton

    - by AreYouSerious
    I have to admit that I can't get enough storage. I have hard drives just sitting around in case I need to move somthing, or I'm going to a friends and either they want something I have or I want something they might have. What I'm going to talk about today is cost effective memory for devices. I don't know how this particualr device will work in a camera, as That's not what I use in my camera, in fact I don't have a camera that doesn't either use SD, or the old compact flash card, that's not so compact anymore. There's this thing that uses two micro sd cards to double the capacity of your memory, and it costs about 4 bucks, without the Micro SD card. I have had one for about a year and was going to throw it away because I couldn't get it to work with my computer, or with my Sony Reader. However I found out by one last ditch effort that this thing works beautifully with my Sony PSP. there is no software to speak of associated with this thing, you simply put in two SD cards of the same size... (if you put in two different sizes it will still work, you'll only double the smallest cards size though) and format through the psp. Viola you know have a 29 GB memory card for your PSP. why is this important ? well for starters you can carry more music and more videos. Second if you have gone the way of the hacker.... you can store more games on your card... There are just a few things you have to note.... I speak from experience... you have to use the usb connection to the PSP to do any file moving, as I said previously said card doesn't play well with my computers or card readers... I not saying it won't work at all, just hasn't work with anything I own. Second. If for some reason you try to Hack/crack your PSP don't attempt to delete a game from the psp, use the usb file browser to remove games. if you delete from the PSP you are likely to have to move all your files off, reformat and start again... just a couple things I have noticed... if I had done something like that.   anyway, Here's a link.... http://www.photofast-adapter.com/  and if you want to buy one, get it off ebay, I've seen them as low as $1.99

  • SolidQ Journal - free SQL goodness for February

    - by Greg Low
    The SolidQ Journal for February just made it out by the end of February 28th. But again, it's great to see the content appearing. I've included the second part of the article on controlling the execution context of stored procedures. The first part was in December. Also this month, along with Fernando Guerrero's editorial, Analysis Services guru Craig Utley has written about aggregations, Herbert Albert and Gianluca Holz have continued their double-act and described how to automate database migrations,...(read more)

  • Adding complexity to remove duplicate code

    - by Phil
    I have several classes that all inherit from a generic base class. The base class contains a collection of several objects of type T. Each child class needs to be able to calculate interpolated values from the collection of objects, but since the child classes use different types, the calculation varies a tiny bit from class to class. So far I have copy/pasted my code from class to class and made minor modifications to each. But now I am trying to remove the duplicated code and replace it with one generic interpolation method in my base class. However that is proving to be very difficult, and all the solutions I have thought of seem way too complex. I am starting to think the DRY principle does not apply as much in this kind of situation, but that sounds like blasphemy. How much complexity is too much when trying to remove code duplication? EDIT: The best solution I can come up with goes something like this: Base Class: protected T GetInterpolated(int frame) { var index = SortedFrames.BinarySearch(frame); if (index >= 0) return Data[index]; index = ~index; if (index == 0) return Data[index]; if (index >= Data.Count) return Data[Data.Count - 1]; return GetInterpolatedItem(frame, Data[index - 1], Data[index]); } protected abstract T GetInterpolatedItem(int frame, T lower, T upper); Child class A: public IGpsCoordinate GetInterpolatedCoord(int frame) { ReadData(); return GetInterpolated(frame); } protected override IGpsCoordinate GetInterpolatedItem(int frame, IGpsCoordinate lower, IGpsCoordinate upper) { double ratio = GetInterpolationRatio(frame, lower.Frame, upper.Frame); var x = GetInterpolatedValue(lower.X, upper.X, ratio); var y = GetInterpolatedValue(lower.Y, upper.Y, ratio); var z = GetInterpolatedValue(lower.Z, upper.Z, ratio); return new GpsCoordinate(frame, x, y, z); } Child class B: public double GetMph(int frame) { ReadData(); return GetInterpolated(frame).MilesPerHour; } protected override ISpeed GetInterpolatedItem(int frame, ISpeed lower, ISpeed upper) { var ratio = GetInterpolationRatio(frame, lower.Frame, upper.Frame); var mph = GetInterpolatedValue(lower.MilesPerHour, upper.MilesPerHour, ratio); return new Speed(frame, mph); }

  • Extremely large spike in traffic on the 1st - 4th of every month from mobile browsers

    - by wsanville
    I've noticed that on the 1st - 4th of the recent months (since January), several sites I maintain are getting thousands of requests from mobile browsers, whereas throughout the rest of the month, the numbers are in the single or double digits. Has anybody else noticed this sort of behavior? I don't have the exact user agents logged, but my analysis software (WebTrends) reports the traffic as mostly iPhone/iPad/iPod, Android, and Blackberry.

  • How could I shutdown, over my network, with one click?

    - by DeLiK
    The question is simple. What would be the script I would have to use to shut down a computer in my network thru ssh. Normaly i would go to command line and: ssh desktop delik@desktop's password: delik@desktop:~$ sudo shutdown -P 0 To power on I created a file and wrote: wakeonlan xx:xx:xx:xx:xx:xx And gave it the executable bit That way to power on it requires only a double click. Would i be capable of doing the same to shutdown?

  • Why does my int, booleans, doubles does not work?

    - by SystemNetworks
    As you see, my code does not work. When armor1 is true, it would add my life. goldA is another class. public void goldenArmor(GameContainer gc, StateBasedGame sbg, Graphics g) { if(armor1==true) { goldA.life = life; goldA.intelligence = intelligence; goldA.power = power; goldA.lifeLeft = lifeLeft; goldA.head(); goldA.body(); goldA.legs(); } } My other class: package javagame; import org.newdawn.slick.GameContainer; import org.newdawn.slick.Graphics; import org.newdawn.slick.Image; import org.newdawn.slick.Input; import org.newdawn.slick.SlickException; /* Note: Copyright(C)2012 System Networks | Square NET | Julius Bryan Gambe.

  • Ubuntu App Contest - Open Source Libraries

    - by Chao
    I just found out about and started looking into the Ubuntu App Contest, and I wanted to double check the contest's stance on using open source libraries built by others that are freely available on the web. I read through the rules and some of the other Q&As, and it sounds like using these libraries would not be allowed (since it could mean the app isn't built from scratch, and the library would not be in the Ubuntu archive - although I could bundle the library with the app), and I just wanted to verify this assumption. Thanks! Chao

  • Opengl-es picking object

    - by lacas
    I saw a lot of picking code opengl-es, but nothing worked. Can someone give me what am I missing? My code is (from tutorials/forums) Vec3 far = Camera.getPosition(); Vec3 near = Shared.opengl().getPickingRay(ev.getX(), ev.getY(), 0); Vec3 direction = far.sub(near); direction.normalize(); Log.e("direction", direction.x+" "+direction.y+" "+direction.z); Ray mouseRay = new Ray(near, direction); for (int n=0; n<ObjectFactory.objects.size(); n++) { if (ObjectFactory.objects.get(n)!=null) { IObject obj = ObjectFactory.objects.get(n); float discriminant, b; float radius=0.1f; b = -mouseRay.getOrigin().dot(mouseRay.getDirection()); discriminant = b * b - mouseRay.getOrigin().dot(mouseRay.getOrigin()) + radius*radius; discriminant = FloatMath.sqrt(discriminant); double x1 = b - discriminant; double x2 = b + discriminant; Log.e("asd", obj.getName() + " "+discriminant+" "+x1+" "+x2); } } my camera vectors: //cam Vec3 position =new Vec3(-obj.getPosX()+x, obj.getPosZ()-0.3f, obj.getPosY()+z); Vec3 direction =new Vec3(-obj.getPosX(), obj.getPosZ(), obj.getPosY()); Vec3 up =new Vec3(0.0f, -1.0f, 0.0f); Camera.set(position, direction, up); and my picking code: public Vec3 getPickingRay(float mouseX, float mouseY, float mouseZ) { int[] viewport = getViewport(); float[] modelview = getModelView(); float[] projection = getProjection(); float winX, winY; float[] position = new float[4]; winX = (float)mouseX; winY = (float)Shared.screen.width - (float)mouseY; GLU.gluUnProject(winX, winY, mouseZ, modelview, 0, projection, 0, viewport, 0, position, 0); return new Vec3(position[0], position[1], position[2]); } My camera moving all the time in 3d space. and my actors/modells moving too. my camera is following one actor/modell and the user can move the camera on a circle on this model. How can I change the above code to working?

  • How to Add a Business Card Image to a Signature in Outlook 2013 Without the vCard (.vcf) File

    - by Lori Kaufman
    When you add a business card to a signature, an image of the business card is inserted into the signature and the vCard (.vcf) file is attached. If you don’t want to attach the vCard file, you can insert the image only into your signature. To insert only the image of your business card without the .vcf file, click People on the Navigation Bar at the bottom of the Outlook window. To get a business card image we can use, we must view the contacts in any form other than People, so we can open the full contact editing window. To do this, click on a different view in the Current View section of the Home tab. We chose to view our contacts in the Business Card format. Double-click on your contact in the current view. The full contact editing window displays with an image of the business card on the right. Right-click on the business card image and select Copy Image from the popup menu. To close the contact editing window, click the File tab and click Close in the menu list on the left. NOTE: You can also click the X in the upper, right corner of the contact editing window to close it. To open the signature editor, click the File tab. Click Options in the menu list on the left side of the Account Information screen. On the Outlook Options dialog box, click Mail in the list of options on the left side of the dialog box. On the Mail screen, click Signatures in the Compose messages section. NOTE: You can also access the Signatures and Stationery dialog box from the Message window for new emails and drafts. Click New Email on the Home tab or double-click an email in the Drafts folder to access the Message window. For more information, see our article about assigning a default signature. In the signature editor, right-click and select Paste from the popup menu. The image is inserted into the signature. You can also use this method to copy a business card image for use in other documents and programs. It’s also possible to insert the vCard (.vcf) file into a signature without the image. We’ll cover that topic tomorrow.

  • Windows 8 Initial User Experience

    Today is the second day I'm using a Windows 8 laptop.  Load up time is fast, and changing applications is very smooth.  However, I keep finding myself hitting the windows key (double-clicking a PDF file, and, what?  How do I get back?)Other than that, the experience has been fine.  So far this has not been any worse than other windows upgrade experience I had so far.  No bad news is good news here.

  • Generating tileable terrain using Perlin Noise [duplicate]

    - by terrorcell
    This question already has an answer here: How do you generate tileable Perlin noise? 9 answers I'm having trouble figuring out the solution to this particular algorithm. I'm using the Perlin Noise implementation from: https://code.google.com/p/mikeralib/source/browse/trunk/Mikera/src/main/java/mikera/math/PerlinNoise.java Here's what I have so far: for (Chunk chunk : chunks) { PerlinNoise noise = new PerlinNoise(); for (int y = 0; y < CHUNK_SIZE_HEIGHT; ++y) { for (int x = 0; x < CHUNK_SIZE_WIDTH; ++x) { int index = get1DIndex(y, CHUNK_SIZE_WIDTH, x); float val = 0; for (int i = 2; i <= 32; i *= i) { double n = noise.tileableNoise2(i * x / (float)CHUNK_SIZE_WIDTH, i * y / (float)CHUNK_SIZE_HEIGHT, CHUNK_SIZE_WIDTH, CHUNK_SIZE_HEIGHT); val += n / i; } // chunk tile at [index] gets set to the colour 'val' } } } Which produces something like this: Each chunk is made up of CHUNK_SIZE number of tiles, and each tile has a TILE_SIZE_WIDTH/HEIGHT. I think it has something to do with the inner-most for loop and the x/y co-ords given to the noise function, but I could be wrong. Solved: PerlinNoise noise = new PerlinNoise(); for (Chunk chunk : chunks) { for (int y = 0; y < CHUNK_SIZE_HEIGHT; ++y) { for (int x = 0; x < CHUNK_SIZE_WIDTH; ++x) { int index = get1DIndex(y, CHUNK_SIZE_WIDTH, x); float val = 0; float xx = x * TILE_SIZE_WIDTH + chunk.x; float yy = y * TILE_SIZE_HEIGHT + chunk.h; int w = CHUNK_SIZE_WIDTH * TILE_SIZE_WIDTH; int h = CHUNK_SIZE_HEIGHT * TILE_SIZE_HEIGHT; for (int i = 2; i <= 32; i *= i) { double n = noise.tileableNoise2(i * xx / (float)w, i * yy / (float)h, w, h); val += n / i; } // chunk tile at [index] gets set to the colour 'val' } } }

  • Write and fprintf for file I/O

    - by Darryl Gove
    fprintf() does buffered I/O, where as write() does unbuffered I/O. So once the write() completes, the data is in the file, whereas, for fprintf() it may take a while for the file to get updated to reflect the output. This results in a significant performance difference - the write works at disk speed. The following is a program to test this: #include <fcntl.h #include <unistd.h #include <stdio.h #include <stdlib.h #include <errno.h #include <stdio.h #include <sys/time.h #include <sys/types.h #include <sys/stat.h static double s_time; void starttime() { s_time=1.0*gethrtime(); } void endtime(long its) { double e_time=1.0*gethrtime(); printf("Time per iteration %5.2f MB/s\n", (1.0*its)/(e_time-s_time*1.0)*1000); s_time=1.0*gethrtime(); } #define SIZE 10*1024*1024 void test_write() { starttime(); int file = open("./test.dat",O_WRONLY|O_CREAT,S_IWGRP|S_IWOTH|S_IWUSR); for (int i=0; i<SIZE; i++) { write(file,"a",1); } close(file); endtime(SIZE); } void test_fprintf() { starttime(); FILE* file = fopen("./test.dat","w"); for (int i=0; i<SIZE; i++) { fprintf(file,"a"); } fclose(file); endtime(SIZE); } void test_flush() { starttime(); FILE* file = fopen("./test.dat","w"); for (int i=0; i<SIZE; i++) { fprintf(file,"a"); fflush(file); } fclose(file); endtime(SIZE); } int main() { test_write(); test_fprintf(); test_flush(); } Compiling and running I get 0.2MB/s for write() and 6MB/s for fprintf(). A large difference. There's three tests in this example, the third test uses fprintf() and fflush(). This is equivalent to write() both in performance and in functionality. Which leads to the suggestion that fprintf() (and other buffering I/O functions) are the fastest way of writing to files, and that fflush() should be used to enforce synchronisation of the file contents.

  • How do I run an executable file from a pendrive?

    - by user64720
    I am trying to run Portable Truecrypt from a USB Pendrive. I already extracted the package and all but the only way it really opens Truecrypt is if the executable is on my home folder. It never works when the executable is on the pendrive. I have tried to go to permissions and set "allow to run as an application" but anyway when double-clicking, the same alert comes up: Unable to present media/Kingston/usr/bin/truecrypt, there is no application installed for executable files.

  • Programming Language most relevant to the Financial sector?

    I am a freshman in college and doing a software engineering/ finance double major. I've been learning programming on my own and have a good bit of familiarity with php by now. I was wondering what you guys think the most relevant programming language is for financial/investment banking use? I have read this thread: Books on developing software for financial markets/investment banks I want to start learning/reading up on a language (the basics not financial/quant stuff) to set a foundation for the future financial/quant stuff.

  • Creating an object that is ready to be used & unset properties - with IoC

    - by GetFuzzy
    I have a question regarding the specifics of object creation and the usage of properties. A best practice is to put all the properties into a state such that the object is useful when its created. Object constructors help ensure that required dependencies are created. I've found myself following a pattern lately, and then questioning its appropriateness. The pattern looks like this... public class ThingProcesser { public List<Thing> CalculatedThings { get; set; } public ThingProcesser() { CalculatedThings = new List<Thing>(); } public double FindCertainThing() { CheckForException(); foreach (var thing in CalculatedThings) { //do some stuff with things... } } public double FindOtherThing() { CheckForException(); foreach (var thing in CalculatedThings) { //do some stuff with things... } } private void CheckForException() { if (CalculatedThings.Count < 2) throw new InvalidOperationException("Calculated things must have more than 2 items"); } } The list of items is not being changed, just looked through by the methods. There are several methods on the class, and to avoid having to pass the list of things to each function as a method parameter, I set it once on the class. While this works, does it violate the principle of least astonishment? Since starting to use IoC I find myself not sticking things into the constructor, to avoid having to use a factory pattern. For example, I can argue with myself and say well the ThingProcessor really needs a List to work, so the object should be constructed like this. public class ThingProcesser { public List<Thing> CalculatedThings { get; set; } public ThingProcesser(List<Thing> calculatedThings) { CalculatedThings = calculatedThings; } } However, if I did this, it would complicate things for IoC, and this scenario hardly seems appropriate for something like the factory pattern. So in summary, are there some good guidelines for when something should be part of the object state, vs. passed as a method parameter? When using IoC, is the factory pattern the best way to deal with objects that need created with state? If something has to be passed to multiple methods in a class, does that render it a good candidate to be part of the objects state?
