• Help comparing Cocos2d and Unity3d for this project [closed]

  - by Omega

  I will not go into details, but I would like to hear your opinions about this: Essentially, my project will be a 2d game, with lots of complex levels, where some might be simple and others might be a bit more deep, with physics, etc. We want to implement our very own online structure: logging in, leaderboards, achievements, friends etc with our own servers. This means no OpenFeint nor GameCenter at all. We expect this game to be very large in both graphics and audio. We wish to use in-app purchases. Now, we considered two options. Cocos2d and Unity3d. We need help deciding using the factors I mentioned before (networking, good performance even for a large game in terms of graphics and audio like this, in-app purchases, etc) which option would fit better this? Technically, both options can create 2d games. I'd like to hear your opinion.

• How can I redirect any kind of access to my site to somewhere else, except for me?

  - by Omega

  My site, www.example.com has a MyBB forum installation, and has many users constantly checking it out. I would like to make a major change to it - basically, I want to delete everything it has and start clean. However, this rebuilding process may take me hours since I need to do a lot of things. Thus, whenever an user tries to enter any part of my site (www.example.com, www.example.com/blog etc), the user will always be redirected to www.example.com/underconstruction so they can see a nice HTML site explaining the current situation. But not only that - while I am configuring my site, I need to visit it myself to make sure things do work live. So basically, it has to redirect everyone who isn't me. Is that possible in any way? I am using GoDaddy hosting.

• How should I compress a file with multiple bytes that are the same with Huffman coding?

  - by Omega

  On my great quest for compressing/decompressing files with a Java implementation of Huffman coding (http://en.wikipedia.org/wiki/Huffman_coding) for a school assignment, I am now at the point of building a list of prefix codes. Such codes are used when decompressing a file. Basically, the code is made of zeroes and ones, that are used to follow a path in a Huffman tree (left or right) for, ultimately, finding a byte. In this Wikipedia image, to reach the character m the prefix code would be 0111 The idea is that when you compress the file, you will basically convert all the bytes of the file into prefix codes instead (they tend to be smaller than 8 bits, so there's some gain). So every time the character m appears in a file (which in binary is actually 1101101), it will be replaced by 0111 (if we used the tree above). Therefore, 1101101110110111011011101101 becomes 0111011101110111 in the compressed file. I'm okay with that. But what if the following happens: In the file to be compressed there exists only one unique byte, say 1101101. There are 1000 of such byte. Technically, the prefix code of such byte would be... none, because there is no path to follow, right? I mean, there is only one unique byte anyway, so the tree has just one node. Therefore, if the prefix code is none, I would not be able to write the prefix code in the compressed file, because, well, there is nothing to write. Which brings this problem: how would I compress/decompress such file if it is impossible to write a prefix code when compressing? (using Huffman coding, due to the school assignment's rules) This tutorial seems to explain a bit better about prefix codes: http://www.cprogramming.com/tutorial/computersciencetheory/huffman.html but doesn't seem to address this issue either.

• How to store an iOS game save file in multiple devices? (Without remote servers)

  - by Omega

  I've been developing an iOS game for iPhone. My game saves the progress as a couple of .plist documents in the device. I have come to realize that when I install a game in my iPhone, this same game is installed in my iPad. And then it struck me: how would I manage save files? I mean, I'd like the player to be able to continue playing from where they left no matter what device are they using... without using remote servers. What have you done to address this issue?

• Is the Observer pattern adequate for this kind of scenario?

  - by Omega

  I'm creating a simple game development framework with Ruby. There is a node system. A node is a game entity, and it has position. It can have children nodes (and one parent node). Children are always drawn relatively to their parent. Nodes have a @position field. Anyone can modify it. When such position is modified, the node must update its children accordingly to properly draw them relatively to it. @position contains a Point instance (a class with x and y properties, plus some other useful methods). I need to know when a node's @position's state changes, so I can tell the node to update its children. This is easy if the programmer does something like this: @node.position = Point.new(300,300) Because it is equivalent to calling this: # Code in the Node class def position=(newValue) @position = newValue update_my_children # <--- I know that the position changed end But, I'm lost when this happens: @node.position.x = 300 The only one that knows that the position changed is the Point instance stored in the @position property of the node. But I need the node to be notified! It was at this point that I considered the Observer pattern. Basically, Point is now observable. When a node's position property is given a new Point instance (through the assignment operator), it will stop observing the previous Point it had (if any), and start observing the new one. When a Point instance gets a state change, all observers (the node owning it) will be notified, so now my node can update its children when the position changes. A problem is when this happens: @someNode.position = @anotherNode.position This means that two nodes are observing the same point. If I change one of the node's position, the other would change as well. To fix this, when a position is assigned, I plan to create a new Point instance, copy the passed argument's x and y, and store my newly created point instead of storing the passed one. Another problem I fear is this: somePoint = @node.position somePoint.x = 500 This would, technically, modify @node's position. I'm not sure if anyone would be expecting that behavior. I'm under the impression that people see Point as some kind of primitive rather than an actual object. Is this approach even reasonable? Reasons I'm feeling skeptical: I've heard that the Observer pattern should be used with, well, many observers. Technically, in this scenario there is only one observer at a time. When assigning a node's position as another's (@someNode.position = @anotherNode.position), where I create a whole new instance rather than storing the passed point, it feels hackish, or even inefficient.

• Ruby using the Gosu framework: why it runs slow first time?

  - by Omega

  I'm creating a Ruby game using the Gosu framework. All good. Sometimes, when I run the game, it has some kind of slow startup, and probably it will be rather slow during the whole game. So I close it and... open it again. It is very likely that it will startup quickly and the whole game will run smoothly and fast. Why is that? What is this phenomenon? Is it faster because of some cache stored or whatever since the first run? (But why would cache be stored? If the app dies, I would expect no references at all etc...) Ruby, Windows 7.

• What are some known approaches to collaborative schema design?

  - by Omega

  If a project has multiple developers, each with useful knowledge & experience that can aide in the design of a schema; what are some known processes to collaboratively plan that schema out? Are there any types of meetings that are useful for this purpose? This would be in contrast to circumstances where projects are started and models are developed unilaterally by coincidence rather than as part of a structured understanding of the domain.

• Why shouldn't I be using public variables in my Java class?

  - by Omega

  In school, I've been told many times to stop using public for my variables. I haven't asked why yet. This question: Are Java's public fields just a tragic historical design flaw at this point? seems kinda related to this. However, they don't seem to discuss why is it "wrong", but instead focus on how can they use them instead. Look at this (unfinished) class: public class Reporte { public String rutaOriginal; public String rutaNueva; public int bytesOriginales; public int bytesFinales; public float ganancia; /** * Constructor para objetos de la clase Reporte */ public Reporte() { } } No need to understand Spanish. All this class does is hold some statistics (those public fields) and then do some operations with them (later). I will also need to be modifying those variables often. But well, since I've been told not to use public, this is what I ended up doing: public class Reporte { private String rutaOriginal; private String rutaNueva; private int bytesOriginales; private int bytesFinales; private float ganancia; /** * Constructor para objetos de la clase Reporte */ public Reporte() { } public String getRutaOriginal() { return rutaOriginal; } public String getRutaNueva() { return rutaNueva; } public int getBytesOriginales() { return bytesOriginales; } public int getBytesFinales() { return bytesFinales; } public float getGanancia() { return ganancia; } public void setRutaOriginal(String rutaOriginal) { this.rutaOriginal = rutaOriginal; } public void setRutaNueva(String rutaNueva) { this.rutaNueva = rutaNueva; } public void setBytesOriginales(int bytesOriginales) { this.bytesOriginales = bytesOriginales; } public void setBytesFinales(int bytesFinales) { this.bytesFinales = bytesFinales; } public void setGanancia(float ganancia) { this.ganancia = ganancia; } } Looks kinda pretty. But seems like a waste of time. Google searches about "When to use public in Java" and "Why shouldn't I use public in Java" seem to discuss about a concept of mutability, although I'm not really sure how to interpret such discussions. I do want my class to be mutable - all the time.

• How to create a manager class without global variables nor singletons?

  - by Omega

  I would like to implement some kind of manager class in my application. It will be in charge of loading textures, processing them, distributing them etc... At first, I wanted to make a global variable that simply contains an instance of my manager class. I found this question: http://stackoverflow.com/questions/4646577/global-variables-in-java. However, the users there seem to recommend to never use global variables. Fine then, I once heard about Singletons, so I though I could use that instead. I mean, creating just one instance of my manager class sounds good. However, I found this other question: When is Singleton appropriate?, which basically tells me that Singletons are, in most scenarios, some kind of anti-pattern. Now I am a bit lost - what other approach can I take to create my manager class, whose only requirement is to be accessible from anywhere?

• I really want to use Xapian on a project, but for the life of me I can't figure out how to install i

  - by Sean

  If this was on a linux box I'd be set, but there's a distinct lack of documentation! I want to use this with c# and the omega indexing app. There doesn't seem to be any documentation on how to actually BUILD xapian & omega on windows (or, pre-compiled binaries which would work fine).

• Setting reply priority on Wifi network with QoS?

  - by Omega

  When using a Station and Access Point that support QoS over Wifi, is it possible to set the priority (= Traffic Identifier = TID = QoS channel) of the reply? For example when sending a ICMP ping request using a high priority (= QoS channel), is it possible to force the station to use that same priority (= QoS channel) when sending the reply? A related question: Is it possible to force the station into using a different QoS channel?

• Does the ASUS P5Q Pro Turbo support Pentium D CPUs?

  - by Omega

  Looking at the ASUS web page as well as others, the Pentium D is not explicitly mentioned as supported on the ASUS P5Q Pro Turbo motherboard. http://ca.asus.com/product.aspx?P_ID=c19zNYHCAXhCqBPq&templete=2 However many sites seem to indicate it is. Is it supported after a BIOS update, or are they simply copy/pasting laundry lists of LGA775 CPUs?

• Recovering corrupted VB.NET Form file?

  - by Omega

  Good day. This question is directly related to this one I made here: http://stackoverflow.com/questions/4911099/there-is-no-editor-available-for-form1-vb-error There, I was working on my VB.NET 2010 Express application, I saved, then a blackout came and now, apparently, I can't view the designer nor code of my Form file (Form1.vb). On StackOverflow, I was recommended to check for the From1.vb file, and try to open it on Notepad. If nothing appeared, it would mean that my file was corrupted. I open it on Notepad, and I get a blank file. It is 27kb, but it only has blank spaces. So I assume it is corrupted. I was told this place was better for dealing with corrupted files, about techniques to recover them. I use Windows7, VB.NET 2010 Express. I run Windows7 on Parallels Desktop, Mac OS X. However, I do not believe that is the problem, most likely it was that damned blackout... this is the first time that happens to me. VB.NET worked just fine for me all time (about a month and half). Thank you.

• Windows 8 Install Hanging at first white-font boot splash

  - by Omega

  I'm trying to install the Windows 8 preview on my Samsung Series 9 (2012, Ivy Bridge). I've done a bit of a custom scheme with this one: I'm using EFI/UEFI on this system. I've seen no indication that this system supports secure boot (yay!) My SSD is set up with GPT Ubuntu is already installed and working great via UEFI. I'm trying to boot the Windows 8 install from a USB stick via UEFI I don't have access to a CD drive. The problem is that the boot seems to hang at the very first splash screen that looks like this. White windows font, the little beads don't show up. My USB stick has an activity light and it does blink for the first few seconds, but then goes back to it's "nobody is talking to me" idle pulse. What I know: UEFI booting is definitely working. Windows 8 for those few seconds seems to have some kind of access to the USB drive. My Series 9 is running the latest BIOS/firmware. Any idea what I might be able to do to get Windows 8 installed??

• Ideal permissions scheme for multiple Apache/PHP sites...

  - by Omega

  I'm hosting multiple sites from one server where each site has it's own user and www directory in their home dir. Currently our web server runs as user nobody(99). We're noticing that to run several popular scripts and engines, they require write access to their own files. As the home directory is owned by the user, not nobody(99), what is the best policy or change in hosting configuration that would: ...make it so that all the various engines and platforms work? ...still allow us to work with files and edit them without having to diddle with permissions as root? Thanks for the advice!

• How to remove a package entirely?

  - by maria

  Hi I'm quite new to Linux, but before using it I was hearing that Windows programs, after uninstallation, leaves a lot of remains on the hard disc, and Linux removes all. I'm using Ubuntu 10.04. To uninstall packages I'm using sudo apt-get autoremove application_name or sudo aptitude purge application_name. Recently I have installed texlive-full and for some reasons I had quickly to uninstall it. After I've entered to terminal updatedb, then locate *texlive* and the output was very long: maria@marysia-ubuntu:~$ locate *texlive* /etc/texmf/fmt.d/10texlive-base.cnf

• Is there a pure object database for PHP?

  - by Omega

  I'm interested in knowing if there is a pure object oriented database for PHP. Something similar to zodb for Python. I'm not really looking for an object-relational mapper. So no active record clones...

• How do I make Views fill the full width of their parent in my Android app?

  - by Omega

  I have the following layout defined for one of my Activities: <?xml version="1.0" encoding="utf-8"?> <TableLayout android:id="@+id/TableLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <TableRow android:id="@+id/TableRow01" android:layout_height="wrap_content" android:layout_width="fill_parent"> <EditText android:text="Resource Name" android:id="@+id/ResourceName" android:lines="1" android:isScrollContainer="false"></EditText> </TableRow> <TableRow android:id="@+id/TableRow02" android:layout_height="wrap_content" android:layout_width="fill_parent"> <Button android:id="@+id/Tile" android:text="Tile"></Button> </TableRow> </TableLayout> The layout renders almost correctly, the only problem is that my text box and my button aren't occupying the full width of their respective rows. I've tried specifying fill_parent for the layout width properties, but to no avail, they still only occupy roughly half of the screen. Documentation overall for Android so far has been great, but there are a few scenarios like this one where I hit an invisible wall! Thanks for all the help!

• What are some best practices for structuring cherrypy apps?

  - by Omega

  I'm writing a cherrypy app and I was wondering what the best way is for structuring my handlers and code for larger applications? I realize assignment is simple trough cherrypy.root, but what are some practices for writing the handlers and assigning them? (Allow me to prove my confusion!) My initial thought is to write a standard handler class that infers a template to run based on the current URL or class/method combination. Then I would assign one instance of that handler multiple times to the path to create pages. I don't see this working however as the recursive references wouldn't work quite right. So, given the fact that I'm already drawing blanks on how my own source code should look, I'd love some pointers and examples! Feel free to ask some detailed questions for me to clarify. While there is plenty of cherrypy tutorial material out there, it tends to only scratch the surface.

• What are some techniques to create scrollable areas?

  - by Omega

  I'm getting started with OpenGL ES on Android and I'd looking to learn some techniques to have a game map larger than the visible area. I'm assuming I've somehow got to ensure that the system isn't rendering the entire scene, including what's outside of the visible area. I'm just not sure how I'd go about designing this! This is for simple 2D top-down tile based rendering. No real 3D except what's inherent in OpenGL ES itself. Would anyone be able to get me started on the right path? Are there options that might scale nicely when I decide to start tilting my perspective and doing 3D?

• Understanding OpenGL Matrices

  - by Omega

  I'm starting to learn about 3D rendering and I've been making good progress. I've picked up a lot regarding matrices and the general operations that can be performed on them. One thing I'm still not quite following is OpenGL's use of matrices. I see this (and things like it) quite a lot: x y z n ------- 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 So my best understanding, is that it is a normalized (no magnitude) 4 dimensional, column-major matrix. Also that this matrix in particular is called the "identity matrix". Some questions: What is the "nth" dimension? How and when are these applied? My biggest confusion arises from how OpenGL makes use of this kind of data.

• VB.NET: Scrollbar "button"?

  - by Omega

  I plan on using a scrollbar for, well, scrolling an image. The image is 200x500, however, the only visible area is 200x250. So I set the max value to 250, and the min value to 0. The idea is that if I drag the scrollbar's button to the bottom, 250 pixels will have moved for the image, right? But wait, the scrollbar's button is.... very small. And the scrollbar is actually pretty long. Is there a way to make the scrollbar's button longer?
