• Visual Studio 2010 - Faster Startup with /nosplash

  - by MikeParks

  I read a blog the other day about the /nosplash switch in Visual Studio. Apparently, it's been around a while and I'm a little late on finding out about it. I figured I'd share it for those of you that come across this and didn't know about it as well. Basically all it does is turn off the Visual Studio splash screen which speeds up initial startup time. It's not a big difference but every little bit helps. I choose speed over looks. You can set the switch by right clicking on Visual Studio, selecting Properties, and adding "/nosplash" on the target Property, so it will look like this: "C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe" /nosplash. Feel free to try it out and see if you like it. You can always change it back by just removing the /nosplash switch when you're done testing. There are plenty more Visual Studio switches out there but this is the main one that came in handy for me.   - Mike

• uswsusp won't hibernate with freeplane and some websites open

  - by Richard

  I installed uswsusp on my laptop to hibernate faster, which works most of the time, but whenever I have freeplane (and some websites in firefox...can't recall which ones but can probably find some) it fails. In order to hibernate, I have to resort to closing the offending program or webpage - but this kinda ruins the point of hibernating... It fails when I try sudo s2disk in a terminal with freeplane open, but strangely works with sudo s2ram --force. When it fails, it simply switches to the black screen with s2disk: Snapshotting system but then returns to the login screen. When I enter my password, the hibernating indicator continues flashing but goes back to the desktop I left when trying to hibernate. When it works, it works as expected from hibernate, shutdown and resume. I saw another thread discuss fglrx modules and to include it in MODULE="fglrx" in /etc/default/acpi-support, but that hasn't helped me. I'm using Ubuntu 11.10 with an ATI graphics card on an Acer Aspire 6920.

• Swap Mouse Buttons on startup

  - by andy boot

  This one bugs me. I fashioned this handy script to swap the left and right mouse buttons over: [My mouse is a Razer] /usr/bin/xinput set-button-map `xinput list | grep 'Razer' | grep -o \=[0-9]* | grep -o [0-9]*$` 3 2 1 4 5 6 7 8 1 10 11 12 13 When I run this in a Terminal it works. When I go to Startup Application Preferences - Add and then literally paste the above into the command field as an 'Additional startup program' It does not run on startup. Why not? I'm using Ubuntu 11-10 but this also applied to the 10-10

• Good practices when writing a parser for a standard file format (such as ePub)

  - by J-F L-R

  I am considering writing an Android reader software that can read ePubs and display them. I checked the ePub standard documents. However, these contain a lot of information. So I am wondering what is the process of implementing a standard for a file format. What are the steps to get a working implementation without passing by parts of the standard? Are there any best practices? Also, is it even possible to program this alone in a reasonable time? From what I have already found out, ePub is basically a zip archive. That means I could probably use zlib to decompress it. The content is in XHTML and CSS, so I believe it should be possible to display it in a WebView. The parts that are missing are writing the code that can read the metadata and manage the non-standard XHTML extensions.

• Programming for Digital frames

  - by spartan2417

  A project has recently come to my attention but i have no idea where to start or even if its possible. The idea revolves around programming a clock that is displayed inside a digital photo frame. The user would then be able to put different pictures corresponding to different times inside a usb pen for example, which would load as soon as you put the usb in. The project itself would be a really neat project - if it was just on a computer. I have no idea if what im talking about it even possible on a digital photo frame and if it is what language? Anyone who has any input at all would be great. My current idea is to maybe have a small device at the back, SSD, that runs the program through a screen, completely by passing standard digital photo frames, again though i dont know how to begin with this. And yes ive tried google (although it helps to know what to google).

Since there is no "default" theme in 2010. So make sure if you wanna reset it to default you know that there is no default, you need to select 'none' :)

• Java vs COBOL programming examples

  - by Jodi

  I am a COBOL programmer, desperately trying to learn and program Java. Although I understand the OO priciples and concepts, I am at a lost putting all together. I am trying to find some examples on how code will look in COBOL vs Java - something a bit more complicated than "hello world" [I am past that initial headache! :-)], that includes OO principles - basically, a decent 1000+ liner in COBOL, with the Java code to work through. After working through book after book, doing the examples, and even writing small java programs at work, I think working through an example I can compare will be the best way to getting my thinking cap converted, and being able to do in Java what I can do after 10 years with COBOL. Can anybody help?

• Attempting to GREP details of a Java error

  - by BOMEz

  I'm running Ubuntu 11 and I'm having some issues with grep. I have a shell script (see below) which essentially checks if a certain Java program of mine is running, if not it runs it. That part works out great! If my Java application throws any kind of exception however I would like to capture that information and email it to myself. How can I go about checking to see if the call to java -jar /bin/MyApp.jar fails? I tried piping it to grep, but that doesn't seem to work. Below is the full script that I've written: #Check if MyApp.jar is running, if not run it. if [ $(ps aux | grep 'java' | grep -v grep | wc -l | tr -s "\n") -eq 0 ] then echo "PacketCapture Starting...\n" java -jar /bin/MyApp.jar echo "PacketCapture Started.\n" else echo "PacketCapture already running.\n" fi

• I can not install Ubuntu 14.04 due to some problem?

  - by user285643

  I have installed Window 8.1 on my HP laptop.Now I want to install Ubuntu 14.04,I try to use "Wubi" but when I use it, after installation on window, when my computer restart i have a message "No root file system is defined" I have read some thread here and i got some solution. One of them are "I must format my partition again, using ext4 format and mount on it". I did it by using Gparted in Try Ubuntu mode, but I got another message "/dev/sda contains GPT signatures,indicating that it has a GPT table. However, it does not have a valid fake msdos partition table,as it should. Perhaps it was corrupted--possibly by a program that does not understand GPT partition table. Or perhaps you deleted the GPT table, and are now using msdos partition table. Is this a GPT partition table?"

• Different behavior when launched from terminal instead of Unity launcher

  - by dgkontopoulos

  I have written two Perl/Gtk programs. When launched from the dash menu, they run just fine. However, if I try to launch them from terminal using the very same command found in their .desktop files, their Unity launcher will be blurry and will remain inactive when clicked, if I keep it in the Unity bar. The problem is solved if the Exec part of the desktop file is replaced with perl path_to_script However, that leads to other problems, including a lintian warning and forcing all Perl GUI applications running from terminal to adopt the same launcher. This issue is quite annoying since one of the programs relies on a different (Python) program in order to be launched and this results in having a blurry and inactive launcher.

• Is there an AIR native extension to use GameCenter APIs for turn-based games?

  - by Phil

  I'm planning a turn based game using the iOS 5 GameCenter (GameKit) turn-based functions. Ideally I would program the game with AIR (I'm a Flash dev), but so far I can't seem to find any already available native extension that offers that (only basic GameCenter functions), so my questions are: Does anyone know if that already exists? And secondly how complex a task would it be to create an extension that does that? Are there any pitfalls I should be aware of etc.? ** UPDATE ** There does not seem a solution to the above from Adobe. For anyone who is interested check out the Adobe Gaming SDK. It contains a Game Center ANE which I've read contains options for multiplayer but not turn-based multiplayer, at least it's a start. Comes a bit late for me as I've already learned Obj-c!

• game engine done, ideas missing

  - by Thoms

  I read at many places how people have this GREAT ideas but are not able to program themselves. I have quite the opposite problem. I have developed game engine, level editor, embedded Lua scripting language, I have even made wrapper for Android and it all works well. But I have no good idea about how to proceed with actual levels; I have no good ideas. The engine itself is very generic and can be used in many game concepts, but I just cannot think of anything useful. Do you have any thoughts on how to proceed? Where should I seek ideas? Who should I ask? I am sorry if this question is a duplicate.

• How to solve cyclic dependencies in a visitor pattern

  - by Benjamin Rogge

  When programming at work we now and then face a problem with visitors and module/project dependencies. Say you have a class A in a module X. And there are subclasses B and C in module Y. That means that module Y is dependent on module X. If we want to implement a visitor pattern to the class hierarchy, thus introducing an interface with the handle Operations and an abstract accept method in A, we get a dependency from module Y to module X, which we cannot allow for architectural reasons. What we do is, use a direct comparison of the types (i.e. instanceof, since we program in Java), which is not satisfying. My question(s) would be: Do you encounter this kind of problem in your daily work (or do we make poor architectural choices) and if so, how is your approach to solve this?

• Is there a language offering LISP-like macros with a more complex syntax?

  - by blubb

  LISP's macros are extremely powerful constructs, and the inability to introspect and modify the program itself beyond the method signature level has always struck me as a limitation. Yet I favour "complex" syntax because it tends to be closer to natural language. So far I have failed to find a language which combines a powerful macro mechanism such as LISP's with a naturally looking syntax (1). Is anyone aware of such a language? Footnote: I would consider python to have a naturally looking syntax as it allows constructs like this: if 0 < a < 5 and b in list. The avoidance of braces to structure blocks is irrelevant in this case, though.

• Newbie needs to learn basic file management

  - by Leo in NJ

  I have been using Ubuntu for abut 2 weeks and and still frustrated by simple file operations. I want to find a file called 9.jpg. Every internal command 3-rd party program I have tried also gives me 99.jpg, 999.jpg, lovepotion number9.jpg and a zillion other similar ones. How do you search for an EXACT file name WITHOUT wildcards? This is only my most recent frustration. I'm obviously missing something basic. good tutorial anywhere?

• XNA 4 game for both profiles

  - by Vodácek

  I am writing game in XNA 4 and this version have two profiles hi-def and reach. My problem is that I need to have my game code for each of these profiles and is very uncomfortable to have two projects and do all changes in both of them. My idea was to use preprocessor directive (i am not sure about name of this, http://msdn.microsoft.com/en-us/library/ed8yd1ha%28v=vs.71%29.aspx) and use IF statement at places with problems with profile. There is only problem that program needs to be compiled two times (for each profile) and manually changed directive and project settings to another profile. And my questions are: Is that good way? Is there better and cleaner way how to do this?

• Stateless game design

  - by L. De Leo

  I'm facing a challenge understanding how to program a web version of a card game that is completely stateless. I create my object graph when the game begins and distribute cards to PlayerA and PlayerB so I lay them out on the screen. At this point I could assume that HTML and the querystring is what holds at least some of my state and just keep a snapshot copy of the game state on the server-side for the sole purpose of validating the inputs I receive from the web clients. Still it appears to me that the state of the game is by its nature mutable: cards are being dealt from the deck, etc... Am I just not getting it? Or should I just strive to minimize the side-effects of my functions to the objects that I take as my input? How would you design a stateless card game?

• How often should saving to disk occur in an automatically saving text editor?

  - by lelandmiller

  I am developing a simple text editor and would like the application to save the text automatically. In other words, the user would never have to press a save button. I have seen other applications that do this, and was wondering how often is it safe to write files to disk? From a user experience standpoint, it seems that the more frequently this happens the better, but I am worried about performance and possible disk wear (especially on writes to SSDs). It seems like the operating system disk caching might help avoid these problems, but I also don't know if its safe to rely on that for an application like this. I was planning on writing the whole document to disk at each save, but this just seems terribly inefficient if the OS ends up writing it to disk to frequently, but relying on program unload may lose data in the case of a crash. Does anyone have any experience dealing with this that might be able to help?

• Mouse not clicking properly

  - by RamoneDexter

  Okay guys, here's a tricky one. I'm running 10.10 on my pc but i've had this issue for some time now.I'm having strange issues with the mouse. What happens is when I get into Ubuntu, I can click anything, but as soon as I click something to open a window, run a program, I can no longer click anything EXCEPT the last thing I clicked. When I right click the last thing I clicked, it allows me to click everything normally, but only until I open something new. So for example I'll click the email icon on docky to open up my email client, which opens but is unresponsive until I right click docky. Then if I open an attatchment, I must also right click the MENU bar on my email client. Sometimes it also works if I simply right click on the newly opened window. I have tried this mith mutiple mice and still the same issue.

• hotkeys do not work sometimes in ubuntu 12.04

  - by stepank

  I use Ubuntu 12.04 with Unity 2D and I've stumbled upon this issue: sometimes shortcut keys stop working in some windows. For instance, I have these windows opened usually: Google Chrome, Terminal, Skype, Pidgin. Sometimes everything is OK and shortcuts work no matter what window I hit them from, however, hotkeys hit from Skype (more often) or Pidgin (less often) do not work, but they still work from Terminal or Google Chrome. Moreover, not all hotkeys are affected, the problem holds only for locking the computer (Ctrl + Alt + L) and other custom shortcuts like executing some command or launching a program (I used zenity --entry with [Super | Ctrl] + [some letter: K, N, etc] for testing). Does anyone have a clue what is causing the problem and how to fix it?

• How can I undo this key mapping?

  - by user273872

  First of all sorry my punctuation will be bad. its hard to type when keys are not doing what you expect. Eg it keeps scaring the **** out of me by taking a screen shot when I push the up arrow lolol So anyways, I broke a key on my keyboard and used xkeycaps to remap it to an unused key which worked. But then I realized it screwed up other keys... I think this is the program I used http://www.jwz.org/xkeycaps/man.html And then after doing the modifications I found out how to save them from the second answer in this question How to Map my enter key to a different key down where it says this "When you are happy with your current keymap and want to use it in future X-sessions, run the following command to save it: xmodmap -pke ~/.Xmodmap"
