• Can not export JARS in lwjgl!

  - by NerdyLegend

  I did it before but for some reason it's doing the stupid problem again. I want to export as a regular Jar file, not a folder full of files. I export it like in Oskar Veerhoak. cmd says Exception in thread "main" java.lang.RuntimeException: Resource not found: res/F lubberFlap.png at org.newdawn.slick.util.ResourceLoader.getResourceAsStream(ResourceLoa der.java:69) at com_FlubberSpace.MainFS.main(MainFS.java:118) I tested it out with my other project with the same code pretty much. This is how I load my Textures wood = TextureLoader.getTexture("PNG", ResourceLoader.getResourceAsStream("res/wood.png")); of course it works fine in eclipse but not after export. I havn't tried giving the previous game its' own project, I have it in a package. Can someone record how to export properly? I want a jar file that you just double click to start it. I also want it so nobody can extract the files and see my classes and res.

• android game: how to approach mutliplayer

  - by willmer

  I'm making a single player game that is near completion, and I am already starting to think about giving the game multiplayer. The multiplayer would basically be finding someone to play against, likely in a waiting room or just have a match-making function, and then having a pokemon style battle between the people in real time. I think it would be relatively simple as I'm just sending information about each attack(move chosen and damage) and what it did back and forth, but I'm not sure what resources to consult for this. I am very new to Android/Java development and really just learning as I go. I have heard a bit about Skiller, but I'm still unfamiliar with using other SDK's and how easy it may be. Does anyone have any suggestions as to what SDK's or methods for accomplishing this. I currently have no money to spend on software development, but I'd like to get started on learning how to do this.

• Does Ubuntu One offer Windows Live Sync type services?

  - by Raaaaay

  I'm an Ubuntu convert from Windows and I'm liking it very much. One of the few things I miss in Windows is their Live Sync. I don't know what it's like now or whether it still exists, but at the time (2008/2009), Windows Live Sync lets you sync folders between computers without uploading contents on their server. That is, only the metadata of the subscribed folders are uploaded (things like changelog etc.). I really liked that, and I was wondering if Ubuntu One has an option that does the same thing? At the moment it only seems to have the option to upload all file contents on the web, and I'd rather not do that. If Ubuntu One doesn't have the service similar to Windows Live Sync as described above, then I really recommend it. I would greatly appreciate it if someone can point me to the right place to make my recommendations. Thanks in advance!

I am open to learn new Programming Languages to develop the software for this barcode scanner. From which I see on our meeting. It uses Windows or Windows Mobile as OS. Can someone direct me to a tut site or just tell me what language I should use? Requirements is mostly, Log In, UI Entry of Details + Barcode, Process Button. Connection To SQL Server via Wifi Access Point to call the procedure afterwards. I am not developing a Barcode scanner, I am developing a UI Software like a Mobile App. I tried to google but I dont know what exact keywords I should search for. My question is, what PL is mostly used to develop this kind of softwares.

• Using fix-boot but still stuck

  - by user92498

  I have a laptop I used to use for college that was Ubuntu 10.4 /Vista / Win7. I pulled it out and proceeded to install 12.04 advanced partitioning. It was sda1 ubuntu / swap / vista / and sda5 win7. I deleted the ubuntu, swap and vista, leaving 7 alone. I'm using it now but can't get to win7. I used fix-boot several times using variations on the advanced menus. So I finally purged grub and forced grup-pc in the advanced setting of fix-boot. Here is a link to the report; http://paste.ubuntu.com/1225051/ I'm sure there is a way to edit the grub to get 7 to show as a boot choice and hope someone can point it out for me. Thanks

• I've got two technical degrees but little in the way of experience. How do I get into programming? [closed]

  - by Neonfirelights

  I'm looking for a job, I want to break into programming. I'm looking for the right sort of role and the right place to look for it; I would really appreciate input from someone with industry experience. I've got an excellent academic record: BSc Physics (2:1), MSc Computer Graphics, Vision and Imaging (expecting Merit) from two world ranking universities. I have advanced technical knowledge of C/C++ and Matlab and experience working with C# and VB.NET. Unfortunately I don't have much in the way of commercial experience; unlike a lot of people I know my under-graduate didn't come with a sandwich placement. Where can I go to break into the software industry?

• Hello, World

  - by KyleBurns

  This is the obligatory first posting in which I describe to you my plans for this blog and why you should read it. My plan is very simple – to share with you (and possibly myself along the way) relevant information about tools and techniques that you can use (or perhaps shouldn’t use) to solve problems with code. Most of my employers have paid me to develop solutions using Microsoft tools and technologies, so you will see them heavily represented here. I also plan to avoid having this blog function simply as a link aggregator, so I promise that it will be rare for you to find entries in my blog consisting solely of a link to someone else’s blog or a webcast – if I do have such links they will at least be accompanied by commentary. This is my first venture into the world of blogging, so please let me know how I'm doing (be nice) and feel free to suggest/request topics for future entries.

• Dual monitor not working after an update

  - by Nimonika

  I did a package manager update yesterday and it turns out that my dual monitor setup has stopped working. I have poor vision so I really need to connect to a much bigger screen, but since yesterday, when I connect the screen to my laptop, the screen does not automatically reset itself to the laptop display. Even after lots of trial and error with the display settings, I am getting different dispalys on the laptop and external screen and right now only the big screen is active while the laptop has blanked out. Please can someone help me setup my dual screens for 11.10 properly. lspci -v | grep -i vga output 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) (prog-if 00 [VGA controller]

• SSIS is Case-Sensitive

  - by andyleonard

  Introduction SSIS is case-sensitive even if the database is case-insensitive. Imagine... ... you work in an ETL shop where someone who believes in natural keys won the Battle of the Joins. Imagine one of your natural keys is a string. (I know it's a stretch... play along!). Let's build some tables to sketch it out. If you do not have a TestDB database, why not? Build one! You'll use it often. Use TestDB go Create Table SSIS1 ( StrID char ( 5 ) , Name varchar ( 15 ) , Value int ) Insert Into SSIS1...(read more)

• How can I add a custom item to the Sound Indicator?

  - by con-f-use

  One of the strength of Unity are the various standardized indicators. I want to customize the sound indicator with an additional menu entry that runs a small shell script. I'm not afraid of a little Python code and I hope someone can point me to the right subroutine in the right file. I suspect that will be fairly easy but all the indicators are just so bloated that I can't look through their code in a reasonable time. Any help is appreciated. I know it is possible as the marvelous Skype-Wrapper does it.

• Would I benefit changing from PHP to Node.js (in context)

  - by danneth

  The situation: We are about to roll out what is essentially a logging service. As we are rather PHP heavy, the current implementation use it. We will have about 200 computers (most on the same network) that will each send, via HTTP POST, around 5000 requests/day. With each request containing about 300 bytes of data. The receiving end is hosted at Amazon and is a very simple PHP form with some simple validation that puts everything in a database. Now, I've recently been introduced to Node.js and I'm curious as to if it would be a good fit for the backend here. Granted I could easily build something to test this. But since I haven't fully grasped the async-methology I would really like someone with experience to explain it to me.

• How can you build a C++ library to produce a .lib file for use in another project?

  - by Codereview

  I tried to use Cmake for the first time, I tried adding a library to my project (Specifically, PhysFS) but then I understood that the library had no .lib file or .a file at all, so I have to build those somehow. I have no clue where to even start around going this, what should I do? Someone suggested I'd go to the project folder and type "Cmake ..." then "Make ..." but I was clueless as to how I'd do that. How would I build the library headers and source files in a .lib file that I can link in C::B? I'm using Windows XP SP3

• In what way I can implement packet filtering function in C++/C#?

  - by Network study

  Background: I am going to design a firewall-like application (with GUI) which will include several functions such as Packet sniffing and packet filtering. Both of the functions should be implemented to support different protocol levels including application, transport, network and link layer. I only know a little in C#.Net programming to perform the IP packet sniffing. It is also known that packet filtering requires the techniques in WFP or LSP and packet sniffing in application requires dll hooking. Questions: I am not sure which programming language(either C++ or C#) would be suitable for designing such an application described above. If I want to implement the packet filtering function, any libraries will be needed? edit01: Someone suggest that winDivert would be helpful, is it true?

• How can I redirect the contents of a file to the pastebinit command? [duplicate]

  - by Tim

  This question already has an answer here: How to submit a file to paste.ubuntu.com without graphical interface? 2 answers Whenever I was to store something to show someone here, I run command-with-output | pastebinit. That returns the link to the paste online. For example: echo timtjtim | pastebinit gave me the link paste.ubuntu.com/8010000 Which I can share. How can I do this with a file - for example a log file. Surely I don't have to open - > copy all - > open paste.ubuntu.com -> paste it?

• ASUS VX-6 Laptop Wireless not connecting

  - by user2152790

  Someone posted a script a couple days ago, here is my output.Pastebin I can see wifi SSIDs in network, but cannot connect to mine. The only time wifi worked on 13.10 was in the Live CD, but wifi stopped working as soon as install process started. Did below but made no difference. sudo apt-get install bcmwl-kernel-source sudo modprobe -rv brcmsmac sudo modprobe -v wl What I do next? I tried Software&Updates and it showed 1 proprietary driver in use. This sounds like a WPA/WPA2 issue? Wifi works when I tried Zorin OS 7.1, wifi always worked in windows 7.

• Can a high FPS negatively affect how a program runs?

  - by rphello101

  Yeah I know this is a broad question and will get down rated, I'm just hoping for some answer before it gets closed. Anyway, I'm using Slick 2D/Java to play around with graphics. I'm having some trouble with trying to move an image. The weird thing is, the code works just fine on my laptop, but the image sporadically moves to (0,0) and stops on my desktop. The only difference between the two is that it says the FPS is about 500 on my laptop and 6600 on my desktop. Can that affect it or does someone have any ideas for what to check on?

• how to get from 1 byte to 2 bytes

  - by dhblah

  I just got something I can't understand, so we have 1 byte, which is 8 bits, which is 2^8. Now 2 bytes should be 2 * 1 byte, which is 2 * 2^8 = 2^9, but actually 2 bytes is 2^16. What I'm missing here? I mean, it seems like 2 bytes isn't 2 * 1 byte, it's more like 1 byte * 1 byte, but this should give you byte^2, which doesn't make sense. Can Please someone explain me some concept I am getting wrong here? Thanks in advance.

• How can I play different sounds each time I startup?

  - by user82171

  I have read questions on Changing startup sound in Ubuntu and Changing startup music in Ubuntu. I understand how to rename 'desktop-login.ogg' and copy the sound I want as 'desktop-login.ogg'. My question is - is there a way I can play different sounds each time I login? It may sound silly, but if possible I would like to play different sounds. I am guessing that this may be perhaps possible by running some kind of script which replaces/renames the desktop-login.ogg file each time I shutdown, so that a new file is ready to be played on the next startup. But I don't know how to copy a new file from a particular folder to desktop-login.ogg upon each shutdown, nor do I know where the script should reside. I would appreciate it if someone could tell me how to do it, or if there is an easier way of doing this. Thank you

• Popper Email Notifier not working

  - by Joel

  Using Maverick 64bit I downloaded Popper Email Notifier today. Installed it from the v023 deb. https://launchpad.net/popper I configured it, and the TEST tab shows I configured everything properly. I can't get Popper to appear in the notification menu. I have restarted gnome-pannel, restarted my computer, reinstalled the app. No luck. I checked the /usr/share/indicators/messages/applications/ folder, and there's only the defaults there. Anyone know how to fix this? Even if someone knows what file I can drop into that folder to make it work that'd be great. Edit: I wonder if it's because I removed the evolution-indicator package? Thanks!

• How to design an interface, where things need to be called in a specific sequence?

  - by Vorac

  The task is to configure a piece of hardware within the device, according to some input specification. This should be achieved as follows: 1) Collect the configuration information. This can happen at different times and places. For example, module A and module B can both request (at different times) some resources from my module. Those 'resources' are actually what the configuration is. 2) After it is clear that no more requests are going to be realized, a startup command, giving a summary of the requested resources, needs to be sent to the hardware. 3) Only after that, can (and must) detailed configuration of said resources be done. 4) Also, only after 2), can (and must) routing of selected resources to the declared callers be done. A common cause for bugs, even for me, who wrote the thing, is mistaking this order. What naming conventions, designs or mechanisms can I employ to make the interface usable by someone who sees the code for the first time?
