• Develop for Desktop and Mobile at once

  - by Hola Soy Edu Feliz Navidad

  I need to develop a programm that is going to read some information from a special USB device and access information via Web Socket (socket.io preferred). My client wants to deploy this app on Mac OS X, Windows, Android and iOS. I was looking for development softwares valid for both: Desktop and Mobile, but it is still not clear for me and that´s what I found. Unity - Looks very good but to create a native plugin for reading from the device it lloks like I need the PRO edition. Adobe Air - Looks good but I´m not sure if I can write Native Plugins for all wanted platforms. LiveCode - Still inmature (lots of bugs) and I don´t know if it is possible to write native plugins for my device. Is there any other good platform for my case? What´s your option?

• Is there a data structure for this type of list/map?

  - by Nick

  Perhaps there's a name for what I want, but I'm not aware of it. I need something similar to a LinkedHashMap in Java, but where it returns the 'previous' value if there's no value at the specified key. That is, I have a list of objects stored by an integer key (which is in units of time in my case): ; key->value 10->A 15->B 20->C So, if I were to query for a value for key 0-9, it would return null. The special part is if I queried for something 10 <= i <= 14 it would return A. Or, for i = 20, it would return C. Is there a data structure for this?

• background animation algorithm for single screen

  - by becool_max

  I’m writing simple strategy game (in xna), and would like to have an animated background. In my game all the actions happens inside one screen and thus standard parallax effect does not look appropriate. However, I found a video of a game with suitable background animation for my game http://www.youtube.com/watch?v=Vcxdbjulf90&feature=share&list=PLEEF9ABAB913946E6 (from 3 to 6s, while main character stays at the same place). What is the algorithm to do this stuff? It would be nice if someone can provide a reference for a similar example (language is not important).

• Using replacement to get possible outcomes to then search through HUGE amount of data

  - by Samuel Cambridge

  I have a database table holding 40 million records (table A). Each record has a string a user can search for. I also have a table with a list of character replacements (table B) i.e. i = Y, I = 1 etc. I need to be able to take the string a user is searching for, iterate through each letter and create an array of every possible outcome (the users string, then each outcome with alternative letters used). I need to check for alternatives on both lower and uppercase letters in the word A search string can be no longer than 10 characters long. I'm using PHP and a MySQL database. Does anyone have any thoughts / articles / guidance on doing this in an efficient way?

• Touchpad & TrackPoint (ThinkPad L520) suddenly unresponsive

  - by yesyoar

  My mother has a problem with her ThinkPad L520 notebook (Ubuntu 11.10, Unity). She boots the device, everything works fine at first. But then, out of nowhere, her touchpad + trackpoint stop working. She can't click or drag the mouse. If she connects an external mouse, she can move the pointer and click (but the internal touchpad or trackpoint still don't work). She already updated everything through the update manager, but still no success...like I said, sometimes it works, sometimes it doesn't. There are no 'special' mouse drivers installed. What can I do to fix this? Thank you for your help! :)

• OpenGL : Keeping alpha in a render buffer

  - by Cyan

  In my current task, i need to render a texture into a render buffer, in order to work on it (apply special filters) there. The result is then considered a "new texture", which is later displayed. This works fine, except when the texture contains some transparent/semi-transparent parts. My current guess it that, within the render buffer, the texture is "merged" with a kind of "grey background". In this case, it obviously impacts the R,G,B color components of transparent pixels. I've yet to find a way around this. Even manually assigning alpha after the rendering process doesn't save the day for semi-transparent pixels, which RGB are "tainted" by the grey background.

• using ubuntu command line to replace text in huge file

  - by user299331

  hi i have a huge xml file that i must work with. right now the file is only 1 line that contains about 2 million characters which represent 30,000 records. there are no carriage returns or linefeeds whatsoever. what i need to do is make each record on its own line. new records begin with "" and end with "". i've been looking around here and it seems the tools to use are: sed, tr or awk but i'm not sure which is most appropriate. i've tried this to no avail: tr '<ROW' '\012 <ROW' <source.xml |tee destination.xml above seems to output some pretty weird stuff so i must be way off here. maybe its that "<" character that is the problem?

• C++ function returning pointer, why does this work ? [migrated]

  - by nashmaniac

  So heres a simple c++ function what it does it take an array of characters as its argument and a integer n and then creates a new character array with only n elements of the array. char * cutString(char * ch , int n){ char * p = new char[n]; int i ; for(i = 0 ; i < n ; i++) p[i] = ch[i]; while(i <= n ){ p[i++] = '\0'; } return p ; } this works just fine but if I change char * p = new char[n]; to char p[n]; I see funny characters what happens ? What difference does the former make also p is a temporary variable then how does the function returns it alright ?

• Test if char is '0'-'9' [migrated]

  - by Chris Okyen

  My Java code is // if the first character is not 0-9 if( (((input.substring(0,0)).compareTo("1")) < 0 || (((input.substring(0,0)).compareTo("9")) < 0)); { System.out.println("Error: The first digit of the temperature is not 1-9. Force Exiting Program. "); System.exit(1); // exit the program } But it slips through even with input like '1123' or '912' or '222', and gives this error message. Whether I have it 0 for first and < 0 for the second, or 0 and 0, or < 0 and < 0, or even < o and 0... How come?

• &ldquo;Using the MVVM pattern in Windows 8&rdquo; in MSDN Magazine

  - by Laurent Bugnion

  These days I am swimming in Windows 8 code, and I must say it is a good feeling. This gives me the occasion to push MVVM Light and a few other components of mine to their limits, and to fix or improve a few things on the fly. All this goodness will be available in V4.1 which is scheduled shortly after Windows 8 launch. In spite of the busy schedule, I couldn’t resist writing an article for MSDN magazine about, you guessed it, the MVVM pattern and MVVM Light in Windows 8. It is an article that goes quite in depth in some of the concepts, and provides an app demonstrating how to use them. The article is available for free in the special Windows 8 edition of MSDN magazine that just came out today. Enjoy!       Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• How to begin serious game development (in C++) [closed]

  - by Rondogiannis Aristophanes

  I would like to start developing games. I have tried before Game Maker 8, which was a very easy way to start creating games, if you were new in game development. Then, I tried Unity 3D, which was a much more serious and complete tool to create computer-games, and required some experience. And now, I would like to start creating games, and don't use any special environment or developer, but just code (in C++ preferably). So, here is my question: from where should I begin, if I would like to start programming games? Thanks in advance. Note: I work in ubuntu 10.04, I can also use windows 7, but I prefer ubuntu.

• What should I look into to find a career path?

  - by PetrakovichJ

  I am finishing up my bachelor's degree in computer science and am feeling somewhat burnt out in the field. I enjoy solving problems, programming, and using computers to find said solutions, but I feel that I never really concentrated on anything in particular and so I don't have any specialties or a path in technology to follow. I feel like a 'generic programmer' with nothing special to offer. My question is, where can I look to find this niche? I have interest in the environment, nature, sustainability, and other similar things. Is there something in these areas in particular where specialists are needed? My question is somewhat vague but where did you "find your niche"?

• Temporary animations

  - by Max

  I've been trying to find a tutorial on how to best make animations in Android. I already have some animations for my enemies and my character that are controlled by rectangles and changing rectangleframe between updates using a picture like this: When I'm shooting my enemies they lose HP, and when their HP == 0 they get removed. aslong as im using an arrayList (which I do for all enemies and bullets) I'm fine, since I can just use list.remove(i). But when I'm on a boss-level and the Boss's HP == 0, I want to remove him and play an animation of an explosion of stars before the "End-screen". Is there a preferred way to do temporary animations like this? If you can give me an example or redirect me to a tutorial, I'd be really grateful!

• 2d engine with WebGL

  - by Philipp

  I am currently developing a HTML5 canvas game with a sprite-based 2d engine. The engine is working well so far, but now I thought that I could maybe add some cool graphic effects when I would re-implement the whole engine with WebGL. The whole graphic engine would stay strictly two-dimensional (think of it as a 3d world where the z coordinate of all vertices is 0.0). What I hope to gain from this is the ability to use pixel shaders to create special effects. I also think that the performance could improve. What do you think about that plan?

• Is this a typo in the Artistic License 2.0?

  - by IQAndreas

  I'm not sure if this would fit better in StackExchange/English, but regardless, there is no practical use to the answer, other than to cure my curiosity. Note this sentence at the end of the Artistic License 2.0: THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS IS' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. It does not affect any legal aspects of the license, but is there a reason they mixed the use of single and double quotes on AS IS? The license is so new that this wouldn't have been for "command prompt friendly" reasons. Is there special use or meaning behind this in the English language, or was it a typo?

• Setting Up Your SQL Server Agent Correctly

  It is important to set up SQL Server Agent Security on the principles of 'executing with minimum privileges’, and ensure that errors are properly logged and alerts are set up for a comprehensive range of errors. SQL Server Agent allows fine-grained control of every job step that should allow tasks to be run entirely safely even if they occasionally need special privileges. Can 41,000 DBAs really be wrong?

• IPC (inter-process communication) server to connect different runtimes

  - by wvxvw

  Couple days ago I've spoken to someone who mentioned a server product that has as its main goal the ability to create inter-runtime layer that allows sharing in-memory object between different languages. The person also described the process of creating such layer as defining a number of structs in a special way such that different languages which access the objects would have the same idea of what the data they access looks like. Unfortunately, I forgot what this product is called, and Google didn't help me finding it so far. Would you happen to know what he was talking about?

  - by RubyKing

  How would I look through a string for a word rather then each character in that word. I have my code here and it always seems to find everything that is .obj even if its o or b or j or "." I checked the docuementation here but was unable to find an answer. Here is my code: string &str = *it; if(it->find(".obj")) { cout << "Found .Obj" << endl; } I also tried to use string::compare but that failed.
