• Confusion with Libgdx UI

  - by BrotherJack

  I've started with Libgdx and am currently stumbling about trying to understand how to set up the interface. I have generated the base projects in Eclipse ( < proj-name ,< proj-name -android, < proj-name -desktop, < proj-name -html), and can get the program to display a simple background, play a looping sound file, and draw a tank. I have been having some problems implementing the UI though. I want to make a collapsible interface bar at the bottom of the screen that would contain buttons for movement, and selecting weapons. I'm confused since there appears to be several ways of doing this and the documentation (or tutorials explaining it) tend to be obsolete. How would one go about this? Use a stage for the bar and actors for the widgets? I'm a little lost on this.

• Deploying a very simple application

  - by vanna

  I have a very simple working console application written in C++ linked with a light static library. It is just for testing purposes. Now that the coding part is done, I would like to know the process of actually deploying the program. I wrote a very basic CMakeLists.txt that create makefiles or VS projects to build the sources. I also have a program that calls the static library in order to make some google tests. To me, the distribution of this application goes like this : to developpers : the src directory with the CMakeLists.txt file (multi-platform distribution) with a README.txt and an INSTALL.txt to users : the executable and a README.txt git repo : everything mentionned above plus the sources for testing and the gtest external lib A this point : considering the complexity of my application, am I doing it right ? Is there any reference that would formalize this deployment process so I can get better and go further ? Say I would like to add dynamic libraries that can be updated, external libraries like boost : how should I package this to deploy it in a professionnal way ?

• Arabic disappeared after 12.04 upgrade!

  - by Aboubakr

  Well, I was amongst the 12.04 Beta upgraders, and since then I've lost the ability to write in Arabic, and I've been using Ubuntu since 2008 as an only OS without any issues, and been upgrading since then as well, except on this machine, which received one upgrade from 11.10 to 12.04 and it got messed up. I've added Arabic like usual, but it doesn't change with the keyboard's short-cut, and when I do it manually with the Mouse, then it just doesn't work, and it keeps writing in English instead. I've tried to install some iBus things, and added Arabic-kbd (m17n) but it still remains messy, let alone not having the same layout, and all I want is to get to NORMAL. So, please, is there any way to reset or initialize these keyboard related settings, so I can get back to normal and stop using the Mac just to type in Arabic, or so often using XP over Vbox? And please, no Re-install option! I just can't backup all my work right now, and there are a lot of tasks waiting for me to get them done. Thanks for any kind of support :)

• Network does not connect at boot

  - by Daniel Svozil

  I am on Ubuntu 12.04, fresh install. When I boot a machine, the boot screen says Connecting to network, later it is changed to something like Did not connect, trying for another 60s. However, the network does not connect at the boot. But I can then log in without a network connection, and if I start a network manager service manually from the terminal (sudo service network-manager start), the network is connected without any problems. Please, does anybody know where the problem could be? I don't want to wait more than two minutes every computer restart :-). I am new to Ubuntu (and also to upstart) so I am a bit lost. There is no /var/log/messages, in dmesg I found this record, though it may not be related: init: network-interface (eth1) pre-start process (492) terminated with status 1 init: network-interface (eth1) post-stop process (548) terminated with status 1 Thanks Daniel

  - by Chris Hoffman

  The Task Manager in Windows 8 has been completely overhauled. It’s easier-to-use, slicker, and more feature-packed than ever. Windows 8 may be all about Metro, but the Task Manager and Windows Explorer are better than ever. The Task Manager now manages startup programs, shows your IP address, and displays slick resource usage graphs. The new color-coding highlights the processes using the most system resources, so you can see them at a glance.

• Good book for improving c# skills?

  - by JMarsch

  Hello: I was asked to recommend a good book for a mid-level experienced developer who wants to improve their coding skills (c# developer). I was thinking about: Code Complete: http://www.amazon.com/Code-Complete-Practical-Handbook-Construction/dp/0735619670/ref=sr_1_1?ie=UTF8&qid=1291221928&sr=8-1 The Pragmatic Programmer: http://www.amazon.com/Pragmatic-Programmer-Journeyman-Master/dp/020161622X/ref=sr_1_3?ie=UTF8&qid=1291221928&sr=8-3 or Effective C#: http://www.amazon.com/Effective-Covers-4-0-Specific-Development/dp/0321658701/ref=sr_1_1?s=books&ie=UTF8&qid=1291222038&sr=1-1 What do you think about those? Any other suggestions?

• Custom keybindings without gnome-settings-daemon

  - by Carlito

  I am using Ubuntu 12.04 (Fallback) and I am trying to slim it down, mostly for fun/learning experience. I killed gnome-settings-daemon because I set up my theming from elsewhere. But now some of my keybindings are lost. I think the windowmanager ones are still working, like Alt-Tab and switch workspace. But my mediakeys to change volume and my custom keybindings are not working anymore. Is there a different way to save custom keybindings? Do I really need to run settings-manager to setup my keybindings?

• Which specific practices could be called "software craftsmanship" rather than "software engineering"?

  - by FinnNk

  Although not a new idea there seems to have been a big increase in the interest in software craftsmanship over the last couple of years (notably the often recommended book Clean Code's full title is Clean Code: A Handbook of Agile Software Craftsmanship). Personally I see software craftsmanship as good software engineering with an added interest in ensuring that the end result is a joy to work with (both as an end user and as someone maintaining that software) - and also that its focus is more at the coding level of things than the higher level process things. To draw an analogy - there were lots of buildings constructed in the 50s and 60s in a very modern style which took very little account of the people who would be living in them or how those buildings would age over time. Many of those buildings rapidly developed into slums or have been demolished long before their expected lifespans. I'm sure most developers with a few years under their belts will have experienced similar codebases. What are the specific things that a software craftsman might do that a software engineer (possibly a bad one) might not?

• How do I hire testers by giving them a buggy app for testing their efficiency?

  - by Jay

  My boss wants to recruit testers based on their testing efficiency (number of bugs identified). So, he's shortlisted 5 people and I need to give them an app full of bugs and see how they fare in reporting obvious bugs, and hidden bugs. I know.... it kind of sounds weird. I guess, this is just like the coding world, where you hire a programmer by assessing his/her programming ability (which is a little easier). Once hired, these testers would be testing a java swing app, so their familiarity of testing frameworks/tools is not really required. So, my question here is - How do I go about finding buggy apps (web/non-web), preferably java ones, that I can have the shortlisted testers have a go at? How would you go about this task if your boss asks you to do so? I am kind of clueless at this point - I googled a bit, thought about finding new apps on sourceforge with lots of bugs, but both approaches didn't work for me.

• A bacon- (and module-) saving PowerShell incident

  - by AaronBertrand

  Earlier today I made a big goof. I opened a module in Notepad, intending to use it as the basis for a new module. I was in the process of using "File > Save As" when my phone rang just at the precise instant that, for some reason, made me click on "File > Save" by mistake. After hitting Ctrl+Z 30 times to try to get the old version of the module back, I remembered that Notepad has never had more than one level of Undo. Back when I was coding ASP by hand, I was very well aware of this, but I...(read more)

• Creating my own kill cam

  - by DalexL

  I plan on creating my own kill cam system for a sandbox tool set. After thinking about the mechanics of the kill cam itself, however, I'm quite lost. I'm trying to recreate the ones commonly seen in call of duty games that show, from the view of the killer, the actual killing scene. My Thoughts: -I can't just keep in memory when people kill others because I wouldn't know when to start the 'recording process'. There is on way for me to accurately determine when somebody is 'about' to kill someone. -My only real idea so far is to have a complete duplicate of everything loaded off to the side copying all the movement from the original world but with a 10 second delay. That way, all the kill cams would be 10 seconds long and the persons camera would just be moved to the second world of their killer. My Questions: Is there already an accepted way to do this? Does anybody have any good ideas for something like this? Thanks if you can!

• Shouldn't we count characters of code and comments instead of lines of code and comments? [closed]

  - by Gabriel

  Counting lines of code and comments is sometimes bogus, since most of what we write may be written in one or more lines, depending column count limitations, screen size, style and so forth. Since the commonly used languages (say C, C++, C# and Java) are free-form, wouldn't it be more clever to count characters instead? Edit: I'm not considering LOC-oriented programming where coders try to artificially match requirements by adding irrelevant comments or using multiple lines where less would be enough (or the opposite). I'm interested in better metrics that would be independent of coding style, to be used by honest programmers.

• failure to restore backup from deja dup

I had all my documents... it's very bad for me, all my personal data... lost? Thanks for any help, Layla.

• What job is better for a newbie, one that requires you to create a new program frequently, or something like software maintenance?

  - by MobileDev123

  One of my friends has just completed his college degree and is ready to join the programmers' world. Today he has two offers, one with new projects every time, and another with software maintenance. The remaining factors are not important to him, what he wants to know is which option is better? My experience goes with second option because my first job was the maintenance one and I could learn how my fellow programmers made mistakes while coding . But I soon switched to a new job which required me to create new project every time. I enjoyed both but I must admit that my first job has given me a more advantage today. But it's not necessary that my experience can give benefit to him. But I want to know what is general approach? If I have to give him final verdict on these two, what should I tell him? Edit Everybody deserves one up vote here, I am really learning a lot from you guys.

• New Bing Maps

  - by MikeParks

  Normally I don't stray too far from Programming and TFS on my blog posts but I'm just really impressed with how much Silverlight has improved Bing maps. I use to be big on MapQuest, then hopped over to Google, but now the new Bing Maps have everything I need. The two coolest features are right on the main page. All you have to do is go to http://www.bing.com/maps/explore/, enter your city and hit enter in the search box, then look in the lower left corner under the EXPLORE section. Check out the "What's nearby" and "Restaurants" links. The best part is, if you're interested in doing any Silverlight programming, they have a Bing Maps Silverlight Control Interactive SDK. I was thinking about coding something....but they've pretty much got it down :) Pretty impressive stuff.

• UDK/ UnrealScript class interaction? HUD advice?

  - by Holly

  Beginner basics requested here, While i'm familiar with the basics of OOP programming i've just started looking as UnrealScript for a game i had made in the UDK editor up to now. I have a class that extends UTHUD and another that extends UDKPAWN. I have the pawn destroyed when its been shot 3 times and some basic helloworld text displaying in my HUD but i'm completely lost as to how one would get some sort of feedback between the two classes going on? What i would like to do to start off, is have some text that says something like "Amount of baddies killed: 0" Displayed on the HUD which would then increment each time the player destroyed one of my pawns. I'm sorry if this is an inappropriate question but i've never really worked within a framework like this before and wasn't sure where to go for help to get my footing. All advice appreciated!

• Managing time for success in the industry? [closed]

  - by nvillec

  So about a year ago I decided to pursue programming, specifically game development, as a career. I've always been a pretty avid gamer, from chucking turnips at Shy Guys' faces in the 90s, to downing Heroic Deathwing last week. Just recently though, I've been spending a LOT of time playing games and it's starting to show in my programming classes. Yesterday after a discouraging exam, I put my foot down and vowed to myself to keep the gaming:coding ratio in favor of the one that will hopefully pay the bills later on. I realize that knowing games well is a key part of being a good developer, but as I've been recently shown, there's a threshold of pixelated indulgence that must not be crossed if I'm ever going to land my dream job. I'm assuming many of you are quite enthusiastic about games as well. What advice would you give an aspiring programmer regarding time management? Thanks!! (Also, I'm brand new to Stack Exchange...if this belongs somewhere else, I'm happy to move it)

• How to handle animations?

  - by Bane

  I am coding a simple 2D engine to be used with HTML5. I already have classes such as Picture, Scene, Camera and Renderer, but now I need to work on Animations. Picture is basocally a wrapper for a normal image object, with it's own draw method, but this is unrelated, I'm interested in how animation in 2D games is usually done. What I planned to do, is to have the Animation class as well act like a wrapper for a few image objects, and then have methods such as getCurrentImage, next and animate (which would use intervals to quickly change the current image). I meant to feed the animation a couple of PNG's at inicialisation. Is quickly swapping PNG images acceptable for 2D animation? Are there some standard ways of doing this, or are there flaws in my ways?

• Simple alternating text in Visual Basic 2008

  - by Josh Grate

  I have a simple completed program, but i would like to add one more feature to it but I'm not sure how. I have it set up to send a message automatically every 7 seconds when a text field is selected, repeating the message of course. What I would like for it to do is alternate between two separate messages, instead just repeating the one. I would like the new program to post at an interval of 12 seconds. Can you help me? Here is my coding. Public Class Form1 Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick SendKeys.Send(TextBox1.Text) SendKeys.Send("{ENTER}") End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Timer1.Enabled = True Timer1.Interval = (TextBox2.Text) End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Timer1.Enabled = False End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Timer1.Enabled = False End Sub End Class

• Trying to Integrate Five9 and Apptivio [on hold]

  - by David Mitchell

  Five9 is a calling system application and Apptivio will be used to store client information for purchased products. Specifically what I need is an example code that will allow me to access Five9's CRM system using the access key and transfer a persons first and last name, for example, to Apptivio. The issue is I have never dealt with this type of system and I cannot find any information for it other than the Web2Campaign that was sent to me by Five9. Lets say this is the code from Five9 F9key=first_name&F9key=last_name&first_name=jon&last_name=smith Once this information is placed into Five9 I must update Apptivio with this information. I am lost as to how to send this information to Apptivio.

• How do I reset my Ubuntu user password?

  - by Myself

  I lost my Ubuntu user account password... I saw some other questions on this topic that had answers telling me to restart the computer, press the left shift key after BIOS, go to root, type "passwd [username]" and all this other stuff, but none of that worked. After I typed a new password and retyped it, it gave me an error message saying something like "Authentication Manipulation Error." There was another question complaining about this, but there weren't any useful answers that worked. Does anybody know of a way for me to retrieve or reset my password? Am I doing something wrong with that method I mentioned?

• How to partition my hard drive for Ubuntu use?

  - by Damir

  Till now I was windows user. From now on I want to use only Linux. I have 500Gb HDD. How do I partition it properly? I read that there is no right or wrong way, but still, I am confused. I did something and I have primary partition mounted on / (160Gb) which I believe is a OS and 350Gb extended partition of which I have 4Gb of swap and 346Gb mounted on /home. I got used to C:\ and D:\ partitioning, but I don't see file system in that way. I am lost. Where is what? How can I make C:\ partition for OS and D:\ for apps, movies, music, photos. Or what I want is Windows way and I have to get used to Linux way?
