• Issue with Banshee

  - by Jordan March

  I went to install Banshee using Ubuntu tweak's App button. I clicked the stable ppa, and installed. When it was done, i tried to launch it, it shows up for a split second then closes. So I though it might be having issues with Rhythmbox's associations or something. So I uninstalled Rhythmbox. But same issue. So I try to uninstall Banshee, and it won't, it fails. I thought, well maybe if I tried installing it from the terminal, adding the ppa first (sudo add-apt-repository ppa:banshee-team/ppa) updating apt-get, then sudo apt-get install banshee. But it fails. So now I can't run it, uninstall it, re install it.. or anything. I'm new to linux so I don't know how to go about rebuilding the files. But if anyone has seen this issue before, or has any idea on how to fix this, I would really appreciate the help. Thanks guys

• Press alt + arrow to skip full line? (Or is there an existing shortcut already..? )

  - by Luka Kotar

  I am still a fresh Ubuntu user, and I switched from a Mac. What I can do on Mac, is I can press alt + arrow to jump one word forward or backward, or if I press cmd + arrow, I am able to jump to the start or end of the line. And that's what I would like to do in Ubuntu. I would assign it to the alt key, as ctrl is already used to skip words. I use that function a lot when coding, I like to keep my hands on the keyboard and just not touch the mouse at all, and it just saves me time for not having to hold the arrow key until I get to the end of the line (or the skip-a-word combo for that matter), or grabbing the mouse to click at the end, just to add a semicolon or something like that. It's not a huge deal, but that's just what I'm used to. I still keep my Mac partition for incompatibility issues, but I prefer Ubuntu over Mac. If there is already a shortcut to do that, I'd gladly go ahead and try getting comfortable using it, but if it is not, how could I achieve what I described above, if of course it is even possible? Thanks in advance, Luka.

• Bikeshedding: Placeholders in strings

  - by dotancohen

  I find that I sometimes use placeholders in strings, like this: $ cat example-apache <VirtualHost *:80> ServerName ##DOMAIN_NAME## ServerAlias www.##DOMAIN_NAME## DocumentRoot /var/www/##DOMAIN_NAME##/public_html </VirtualHost> Now I am sure that it is a minor issue if the placeholder is ##DOMAIN_NAME##, !!DOMAIN_NAME!!, {{DOMAIN_NAME}}, or some other variant. However, I now need to standardize with other developers on a project, and we all have a vested interest in having our own placeholder format made standard in the organization. Are there any good reasons for choosing any of these, or others? I am trying to quantify these considerations: Aesthetics and usability. For example, __dict__ may be hard to read as we don't know how many underscores are in there. Compatibility. Will some language try to do something funny with {} syntax in a string (such as PHP does with "Welcome to {$siteName} today!")? Actually, I know that PHP and Python won't, but others? Will a C++ preprocessor choke on ## format? If I need to store the value in some SQL engine, will it not consider something a comment? Any other pitfalls to be wary of? Maintainability. Will the new guy mistake ##SOME_PLACEHOLDER## as a language construct? The unknown. Surely the wise folk here will think of other aspects of this decision that I have not thought of. I might be bikeshedding this, but if there are real issues that might be lurking then I would certainly like to know about them before mandating that our developers adhere to a potentially-problematic convention.

• What's the simplest way to provide a portable, locally running webservice server application?

  - by derFunk

  We have a bigger website running that offers a JsonRpc web service. For offline demonstration purposes I want to realize a portable, locally running webserver with a minimalistic feature replication of the live webservice, and bundle this together with Html files which do Ajax requests to it. This local server executable should have as little dependencies as possible. It's gonna be run and presented by non-devs on non-dev Windows machines, so I would prefer having a simple executable plus the service code - whereas language doesn't matter as long as it is .NET, PHP or Java. I'll need a small database behind which probably will be Sqlite. It's important to say that for some reasons we cannot use the original web service code, but we have to rewrite it new for the local demo server, this is why I want to put minimal effort in the local server tech. An installer for distribution is not mandatory, it's okay to have a zip file with an executable in it which starts up the local webserver. What would you recommend realizing these requirements? I've done some research already, but would love to here your opinions and get some pointers!

• Internationalization messages based in views or in model entities

  - by SJuan76

  I have a small webapp in java and I am adding the internationalization support, replacing texts with labels that are defined in dictionary files. While some texts are obviously unique to each view (v.g. the html title), other refer to concepts from the model (v.g. a ticket, the location or status of such ticket, etc.) As usual, some terms will appear many times in different locations (vg, in both the edition page and in the search page and in the listings I have a "ticketLocation" label). My question is: can I organize the labels around the model concepts (so I have a ticket.location label and I use it everywhere such field is labeled) or should I make a different label for each (so form.ticketLocation and filter.ticketLocation and list.ticketLocation). I would go for the first option; I have searched for tips and the only thing that I see that could hinder me is due to the length of the string disrupting the design, and even for that I would prefer having to add a ticket.locationShort for places where there is not much space. What is your opinion/tips/experience?

• Architecture Question

  - by katie77

  I am writing a rules/eligibility Module. I have 2 sets of data, one is the customer data and the other is the customer products data. Customer data to Customer products data is one to many. Now I have to go through a set of Eligibility rules for each of this Customer product data. For each customer products data, I can say the customer is eligible for that product or decline the eligibility and should move on to the next product record. So in all the rules, I need to have access to customer and customer product data(the particular record that the rules are being executed against). Since all the rules can either approve a product or decline a product, I created an interface with those 2 methods and is implementing the this interface for all the rules. I am passing the Customer data and one product data for all the rules (because rules should be executed on each row of customer product data). An Ideal situation would be having the customer and customer product data available for the rule instead of passing them to each rule. What is the best way of doing this in-terms of architecture?

• How do I get debuild to put the binary in /usr/bin?

  - by SammySP

  I have been recently trying to package a small Python utility to put on my PPA and I've almost got it to work, but I'm having problems in making the package install the binary (a chmod +x Python script) under /usr/bin. Instead it installs under /. I have this directory structure - http://db.tt/0KhIYQL. My package Makefile is like so: TARGET=usr/bin/txtrevise make: chmod +x $(TARGET) install: cp -r $(TARGET) $(DESTDIR) I've used $(DESTDIR), as I understand it to place the file under the debian subdir when debuild is run. I have the txtrevise script, my executable, under usr/bin folder under the root of my package. I also have the Makefile and usr/bin/textrevise in my tarball: txtrevise_1.1.original.tar.gz. However when I build this and look inside of the Debian package, txtrevise is always at the root of the package instead of under usr/bin and will be installed to / instead of /usr/bin. How can I get debuild to put the script in the right place? Thanks. Any help would be greatly appreciated. I'm stumped.

• On Developing Web Services with Global State

  - by user74418

  I'm new to web programming. I'm more experienced and comfortable with client-side code. Recently, I've been dabbling in web programming through Python's Google App Engine. I ran into some difficulty while trying to write some simple apps for the purposes of learning, mainly involving how to maintain some kind of consistent universally-accessible state for the application. I tried to write a simple queueing management system, the kind you would expect to be used in a small clinic, or at a cafeteria. Typically, this is done with hardware. You take a number from a ticketing machine, and when your number is displayed or called you approach the counter for service. Alternatively, you could be given a small pager, which will beep or vibrate when it is your turn to receive service. The former is somewhat better in that you have an idea of how many people are still ahead of you in the queue. In this situation, the global state is the last number in queue, which needs to be updated whenever a request is made to the server. I'm not sure how to best to store and maintain this value in a GAE context. The solution I thought of was to keep the value in the Datastore, attempt to query it during a ticket request, update the value, and then re-store it with put. My problem is that I haven't figured out how to lock the resource so that other requests do not check the value while it is in the middle of being updated. I am concerned that I may end up ticket requests that have the same queue number. Also, the whole solution feels awkward to me. I was wondering if there was a more natural way to accomplish this without having to go through the Datastore. Can anyone with more experience in this domain provide some advice on how to approach the design of the above application?

• Programming During a Crisis

  - by Duracell

  Hello, I'm having difficulty turning this into a proper question, but here goes... Some of you may have heard about the flooding happening in Queensland, Australia. Well, I'm in the inner suburbs of Brisbane right now; the river has been slowly creeping toward my house since Tuesday. When I left for work this morning it was twenty meters down the road when it is normally kilometers away. Within hours of the distater striking, the government already had some pretty good web applications available for people to get information about what was happening and where the flood was predicted to rise. They also set up a database for people to search for the whereabouts of relatives or could register their location for others to see. Has anyone been involved in the development of these kinds of projects before? It's interesting that they could churn out this software in what appeared to be less than a day when the average development house could take weeks at best. In what ways did it differ from a 'normal' project? Any other thoughts?

• OpenGL, objects disappear at a certain z distance

  - by smoth190

  I'm writing a managed OpenGL library in C++, and I'm having a pretty annoying problem. Whenever I set an objects position to -2.0 or lower, the object disappears. And at distances 0 through -1.9, it doesn't appear to move away from them camera. I have a world matrix (which is multiplied by the objects position to move it), a view matrix (which is just the identity matrix currently) and a projection matrix, which is setup like this: FOV: 45.0f Aspect Ratio: 1 zNear: 0.1f zFar: 100.0f using GLMs glm::perspective method. The order the matrices are multiplied by in the shader is world, view, projection, then position. I can move the object along the X and Y axis perfectly fine. I have depth testing enabled, using GL_LEQUAL. I can change the actually vertices positions to anything I want, and they move away from the camera or towards it perfectly fine. It just seems to be the world matrix acting up. I'm using glm::mat4 for the world matrix, and glm::vec3 for positions. Whats going on here? I'm also using OpenGL 3.1, GLSL version 140 (1.4?).

• Scale an image with unscalable parts

  - by Uko

  Brief description of problem: imagine having some vector picture(s) and text annotations on the sides outside of the picture(s). Now the task is to scale the whole composition while preserving the aspect ratio in order to fit some view-port. The tricky part is that the text is not scalable only the picture(s). The distance between text and the image is still relative to the whole image, but the text size is always a constant. Example: let's assume that our total composition is two times larger than a view-port. Then we can just scale it by 1/2. But because the text parts are a fixed font size, they will become larger than we expect and won't fit in the view-port. One option I can think of is an iterative process where we repeatedly scale our composition until the delta between it and the view-port satisfies some precision. But this algorithm is quite costly as it involves working with the graphics and the image may be composed of a lot of components which will lead to a lot of matrix computations. What's more, this solution seems to be hard to debug, extend, etc. Are there any other approaches to solving this scaling problem?

• How to set up a personal Apple developer account now with an eye on transferring app ownership to a company later?

  - by Rinzwind

  I have two Mac applications that I wrote for my own personal use, but I'm considering polishing them up and giving selling them on the Mac App Store a try. It seemed very premature to consider what would happen if either app would become successful enough to make it possible to set up a business around it, or to sell it to another developer. That is, until I read that Apple doesn't make it easy to transfer app ownership. I'm not sure how to best register with the Apple Developer program now to avoid any possible hassle in this respect later. From what I understand, one can really only transfer ownership of a developer account. I'm not sure about the relationship between an Apple ID and an Apple developer account. Does this mean I should at least not use the Apple ID I'm already using for iTunes, but create a second one to use for registering as an Apple Developer? Is there any disadvantage to using separate Apple IDs like this on the same Mac (one ID for Xcode development, the other ID for iTunes/iCloud/App Store/...)? Should one go as far as having a separate Apple ID & Apple developer account per app one develops? Or is there some other solution to take into account the possibility of transferring app ownership?

• Website only displays correctly in IE using compatibility mode?

  - by user21318

  As the resident "IT Whiz" at work (ie: I know how to use a computer) I've been asked to develop a website for our small business. I've altered a wordpress theme for the time being and the company is very happy with the results. The only problem I am having with it at the moment is that for some reason the website does not display correctly and Internet Explorer unless I run it in Compatibility Mode. The main problem that I have is that my menu "slider" (it rotates pictures with links to articles etc) does not display at all, neither does the top menu they are just blink text based links. Even with Compatibility Mode enabled the slider and menus come back but the page is not centered unlike on both Firefox and Chrome. My googling has suggested the most common cause of this is old code but I'm not sure where to be looking. Is it likely in the css file or the actual php? Also any ideas on how to trouble shoot the cause of this? As in is there some dev tools or debugger I can use that would highlight "broken" code for me?

• How can I port msvc++ code with non-dependent names in templates to Linux?

  - by user352382

  I can deal with porting platform dependent functions. I have a problem that the compilers I tried on Linux (clang and g++) do not accept the following code, while the msvc++ compiler does: template <class T> class Base { protected: T Value; }; template <class T> class Derived : public Base<T> { public: void setValue(const T& inValue){ Value = inValue; } }; int main(int argc, char const *argv[]) { Derived<int> tmp; tmp.setValue(0); return 0; } g++ error: main.cpp: In member function ‘void Derived<T>::setValue(const T&)’: main.cpp:11:3: error: ‘Value’ was not declared in this scope I believe this due to the use of a non-dependent name (Value) in the second class. More information. The problem is that I have a very large code base, in which this type of code is used very often. I understand that it is wrong when looking at the standard. However it is very convenient not having to write this-> or Base<T>:: in front of every use of Value. Even writing using Base<T>::Value; at the start of the derived class is problematic when you use ~20 members of the base class. So my question is: are there compilers for Linux that allow this kind of code (with or without extra compiler switches)? Or are there small modifications that will allow this code to compile on Linux?

• Been doing .NET for several years and am thinking about a platform change. Where do people suggest I go?

  - by rsteckly

  Hi, I've been programming in .NET for several years now and am thinking maybe its time to do a platform switch. Any suggestions about which platform would be the best to learn? I've been thinking about going back to C++ development or just focusing on T-SQL within the Microsoft stack. I'm thinking of switching because: a) I feel that the .NET platform is increasingly becoming commodified--meaning that its more about learning a GUI and certain things to click around than really understanding programming. I'm concerned that this will lend itself to making developers on that stack increasingly paid less. b) It's very frustrating to spend your entire day essentially debugging something that should work but doesn't. Usually, Microsoft releases something that suggests anyone can just click here and there and poof there's your application. Most of the time it doesn't work and winds up sucking so much more time than it was supposed to save. c) I recently led a team in a small startup to build a WPF application. We were really hit hard with people complaining about having to download the runtime. Our code was also not portable to any other platform. Added to which, the ram usage and slowness to load of the app was remarkable for its size. I researched it and we could not find a way to optimize it. d) I'm a little concerned about being wedded to the Windows platform. What are the pros and cons of adding another platform and which platform do people suggest? Thanks!

• Ubuntu 13.04 Sound Problem after following weird commands

  - by user206356

  After launching a few commands : echo autospawn = no >> ~/.config/pulse/client.conf #use ~/.pulse/client.conf on Ubuntu <= 12.10 killall pulseaudio $LANG=C pulseaudio -vvvv --log-time=1 > ~/pulseverbose.log 2>&1 My sound does not work. (just with the speakers, with headphones it works but I can not change the volume) The sound icon on the top right corner does show a speaker with a single non continuous line. I can not change the volume; it is frozen. There can be an extremely low output of the sound (I hear something but I am not sure...) It does not show a single output device that is avalaible, not even the "dummie". I have tried to reset pulseaudio, alsa, remove it, purging it, reinstalling it, without having success. EDIT: I have tried launching pulseaudio via the terminal. It worked :D However, I am very surprised why it does not automatically start at the start of the computer. Any ideas ? Here the console output : W: [pulseaudio] authkey.c: Failed to open cookie file '/home/simonm/.config/pulse/cookie': No such file or directory W: [pulseaudio] authkey.c: Failed to load authorization key '/home/simonm/.config/pulse/cookie': No such file or directory W: [pulseaudio] authkey.c: Failed to open cookie file '/home/simonm/.pulse-cookie': No such file or directory W: [pulseaudio] authkey.c: Failed to load authorization key '/home/simonm/.pulse-cookie': No such file or directory

• How do I force the system to look for new sound devices?

  - by John Zeringue

  I have a small flat screen TV (Toshiba) that I often connect via HDMI to my laptop (an HP Pavilion dv4) and use as a computer monitor. When I do this, I prefer to use the TV's speakers, particularly when I'm watching video, because the sound quality is much better. However, when I connect the HDMI cable after turning on my computer (rather than having it plugged in before booting up), Sound Settings does not list the TV as an output device, and I am forced to reboot. I was curious if there is an easier solution to this, perhaps a CLI command to check for new sound outputs. Does anyone know of something like this or have another solution? To clarify, I believe this is a software problem. The HDMI always works, and I can switch my desktop over to the TV at any time. The issue is that, if the HDMI wasn't connected during start up, the TV will not appear as an output option in the Sound Settings GUI. So, unless I'm mistaken, my question is not HDMI specific, but rather a general usage question about manipulating sound settings from the command line.

• "bug" in C++11 text by Stroustrup?

  - by Astara

  I found an apparent contradiction in the c++ text having to do with the result of the c_str() function operating on std:strings (in my copy, the definition and contradiction are on p1040). First it defines the c_str() function as something that produces a 'C-style' (zero-terminated) string, but later it talks about how a C++ c_str value can have embed a 'C'-style, end-of-string terminators (i.e. NUL's) embedded in the string (that is defined by being NUL terminated). Um... does anyone else feel that this is a 'stretching' of the definition of a C-string beyond it's definition? I.e. I think what it means, is that if you were to look at the length() function as applied to the string, it will show a different end of string than using the C-definition of a z-string -- one that can contain any character except NUL, and is terminated by NUL. I likely don't have to worry about it in my of my programs, but it seems like a subtle distinction that makes a C++ c_str, not really a 'C'-string. Am I misunderstanding this issue? Thanks!

• When creating a GUI wizard, should all pages/tabs be of the same size? [closed]

  - by Job

  I understand that some libraries would force me to, but my question is general. If I have a set of buttons at the bottom: Back, Next, Cancel?, (other?), then should their location ever change? If the answer is no, then what do I do about pages with little content? Do I stretch things? Place them in the lone upper left corner? According to Steve Krug, it does not make sense to add anything to GUI that does not need to be there. I understand that there are different approaches to wizards - some have tabs, others do not. Some tabs are lined horizontally at the top; others - vertically on the left. Some do not show pages/tabs, and are simply sequences of dialogs. This is probably a must when the wizard is "non-linear", e.g. some earlier choices can result in branching. Either way the problem is the same - sacrifice on the consistency of the "big picture" (outline of the page/tab + location of buttons), or the consistency of details (some tabs might be somewhat packed; others having very little content). A third choice, I suppose is putting extra effort in the content in order to make sure that organizing the content such that it is more or less evenly distributed from page to page. However, this can be difficult to do (say, when the very first tab contains only a choice of three things, and then branches off from there; there are probably other examples), and hard to maintain this balance if any of the content changes later. Can you recommend a good approach? A link to a relevant good blog post or a chapter of a book is also welcome. Let me know if you have questions.

• Provide A Scrolling "Camera" View Over A 2D Game Map

  - by BitCrash

  I'm in the process of attempting to create a 2D MMO type game with Kryonet and some basic sprites, mostly for my own learning. I have the back end set up great (By my standards) and I'm moving on to actually getting some things drawn onto the map. I cannot for the life of me figure out a solid way to have a "Camera" follow a player around a large area. The view pane for the game is 640 x 480 pixels, and each tile is 32x32 pixels (Thats 20 tiles wide and 15 high for the viewpane) I have tried a couple things to do this, but they did not seem to work out so well. I had a JScrollPane with 9 "Viewpane"-sized canvases in it, and tried to have the JScrollPane move in accordance with the player. The issue came when I reached the end of the JScrollPane. I tried to "Flip" canvases, sending the canvas currrently drawing the player to the middle of the 9 and load the corresponding maps onto the other ones. It was slow and worked poorly. I'm looking for any advice or previous experience with this; any ideas? Thank you! Edit and Clarification: I did not mean to mention Kryonet, I was merely providing peripheral information in case there was something that would help which I could not foresee. Instead of having an array of 9 canvases, why not just have one large canvas loading a large map every once in a while? I'm willing to have "load times" where as with the canvas array I would have none (in theory) to give the user a smooth experience. I could just change the size and location of the map with a modified setBounds() call on the canvas in a layered pane (layered because I have hidden swing items, like inventories and stuff) I'll try it out and post here how it goes for people asking the same question.

• Recommended display/background brightness ratio and UI color schemes [duplicate]

  - by user1306322

  This question already has an answer here: Colour scheme for editor - guidelines or medical reccomendations 3 answers I'm a professional programmer, which means I spend a lot of time staring at various displays. Recently I've been having some problems with my eyes, so I went to talk to several doctors, which all gave me different recommendations as to how bright the background of the room should be in comparison to the display's brightness. It was very confusing, as some of them even agreed with counter-arguments of others, which made it all even less clear. So I'd like to ask the professional programmers, as people who actually have some experience with that. Some of the doctors said that looking at a monitor is like looking at a book, so the brightness ratios should be approximately the same. Others said that background should be as bright as the display itself, because then there is no brightness difference at the edges, and that's what may cause eye fatigue. From my own experience, I can say that reading a book isn't the same as writing or debugging a program, where you have to pay close attention to each symbol, and in books most words are easily recognizable without focusing too hard on them. Also, books are black on white and I myself use the default (dark text, white bg) color scheme for my IDE, but I've seen some programmers use mid-bright text on very dark background color schemes. So I'd like to ask what are the recommended display/background brightness ratios for programming? I'm not sure this site is the right one for this kind of questions, so if you know a better one, please comment.

• Using Git with TFS projects

  If you having been following the updates to CodePlex over the last several months you will have noticed that we added support for Git source control. It is important to the CodePlex team to enable developers to use the source control system that supports their development style whether it is distributed version control or centralized version control. There are many projects on CodePlex that are using TFS centralized version control. But we continue to see more and more developers interested in using Git. Last week Brian Harry announced a new open source project called Git-TF. Git-TF is a client side bridge that enabled developer to use Git locally and push to a remote backed by Team Foundation version control. Git-TF also works great for TFS based projects on CodePlex. You may already be familiar with git-tfs. Git-TFS is a similar client side bridge between Git and TFS. Git-TFS works great if you are on Windows since it depends on the TFS .Net client object model. Git-TF adds the ability to use a Git to TFS bridge on multiple platforms since it is written in Java. You can use it on Mac OS X, Linux, and Windows, etc. Since you are connecting to a TFS Server when using Git-TF make sure you use your CodePlex TFS account name: snd\YOUR_USERNAME_cp along with your password. At this point, you will need to be a member of the project to connect using Git-TF. Resources Git-TF Getting Started Guide Download: Git-TF Git-TF Source on CodePlex

• Mobile web app, styling in percentages; I can't get height to work [migrated]

  - by Mick79

  I am building a mobile app for a band and obviously want it to display well in all the plethora of handsets out there today. I built it at first for my own device and it looks and works great, so now I am reworking it in percentages so that it works in all devices. I have a slider (jquerytools) going on and if i set width to 100% then it is perfectly wide in my iphone and my ipad... success, however I am not having any luck with height. It seems to only accept a height in px. If i set a height in percent it just doesn't display. any ideas? #header{ width:100%; height:198px; position:relative; z-index: 20; box-shadow: 0 0 10px white; } .scrollable { /* required settings */ position:relative; overflow:hidden; width: 100%; height:100%; box-shadow: 0 0 20px purple; z-index: 20; } .scrollable .items { /* this cannot be too large */ width:500%; height:100%; position:absolute; clear:both; box-shadow: 0 0 30px green; } .items div { float:left; width:20%; height:100%; } /* single scrollable item */ .scrollable img { float:left; width:100%; height:100%; /* height:198px; */ } /* active item */ .scrollable .active { border:2px solid #000; position:relative; cursor:default; } `

• Tomcat 7 vs. ehCache Standalone Server (Glassfish) Configuration with RESTful Web Services

  My requirements consist of using ehCache to send and store data via RESTful web service calls. The data can be stored in-memory or via the filesystem... Never used ehCache before so I am having some issues deciding on which bundle to use. Have downloaded the following bundles: ehcache-2.6.2 ehcache-standalone-server-1.0.0 (1) What is the difference between the two? It seems the ehcache-2.6.2 contains src and binaries, which essentially enables one to bundle it with their webapps (by putting the compiled jar or binaries inside the webapp's WEB-INF/lib folder). But it doesn't seem that it has support for Restful web services. Whereas, ehcache-standalone-server-1.0.0 (comes with an embedded Glassfish server and has support for REST & SOAP) can be used to run as a standalone server. If I my answers to my own question are correct, then that means, I should just use the standalone server? (2) My requirements are to setup ehCache (with REST support) on Tomcat 7. So, how could I setup ehCache on Tomcat 7 as a separate app with REST & SOAP support? Thank you for taking the time to read this...
