  • Ubuntu ONE (Windows BETA) locks up - What to do?

    - by Zusch
    OS: Windows XP SP3 Hardware: Dell Precision M4400 (Laptop) CPU: Core2Duo T9600 Mem: 4 GB Installer- setup, first start and account- setup of UbuntuONE Windows client passed with no problems. After restart of UbuntuONE, the CPU- usage shows 50% (100% core usage). Exit- command (from context-menu) hides the trayicon, but the program is still working excessive in background (50% cpu- / 50 MB memory- usage), until UbuntuOneClient.exe is killed by the taskmanager. What's going on ?

  • Can coding style cause or influence memory fragmentation?

    - by Robert Dailey
    As the title states, I'd like to know if coding style can cause or influence memory fragmentation in a native application, specifically one written using C++. If it does, I'd like to know how. An example of what I mean by coding style is using std::string to represent strings (even static strings) and perform operations on them instead of using the C Library (such as strcmp, strlen, and so on) which can work both on dynamic strings and static strings (the latter point is beneficial since it does not require an additional allocation to access string functions, which is not the case with std::string). A "forward-looking" attitude I have with C++ is to not use the CRT, since to do so would, in a way, be a step backwards. However, such a style results in more dynamic allocations, and especially for a long living application like a server, this causes some speculation that memory fragmentation might become a problem.

  • What are options for 3rd Party Centralized Software Settings Management?

    - by Jeff Martin
    I am an architect in an enterprise looking to build a SaaS solution. Our products are distributed over many different deployable containers, Web Services, Web UI's, etc. I am looking for some open-source or 3rd party software solution to manage the settings of our application. These would be similar to the settings you might find in Word or Eclipse or Visual Studio. The settings would control various behaviors and features of the product. (Probably not settings like which database to connect to but more like, should I show line numbers on the page or not by default..). Ideally, we would be able to store values for different dimensions (by tenant, by user, by application environment... ) Because we have so many different deployables, I am looking for a centralized solution that can provide a web service that each of the deployables can get their individual settings from. Does anyone know of a centralized service providing this sort of features or give me some help in searching for an alternative to rolling our own?

  • Nautilus-Action conf. tool - crafting a "set as background" action

    - by EgyptBeast
    I wanted to create an option in the context menu to set the clicked picture to current desktop background (just like in Windows). I read the the nautilus action help but I couldn't figure it out. This is by far the command I could craft: gsettings set org.gnome.desktop.background picture-uri file://$PWD/ What I need: A command that correctly sets the current image to be the desktop background This command should only appear to the proper files (picture extenstions like .jpg)

  • How to disable mouseover popup icons on launcher?

    - by John
    If an application is open and its icon is contained in the launcher panel, moving the mouse over the launcher icon will cause a very annoying popup icon to appear, showing a small image of the open application. It is annoying because it lingers too long and covers other information. For example, it covers the menus that appear when I right-click on a launcher panel icon. How do I disable these mouseover popups? I don't necessarily want to disable the "text" mouseover popup, I only want to disable the image popups. Thanks. Ubuntu 12.04, new install.

  • Designing call center applications, what to consider.

    - by Espen Schulstad
    We have customers calling in to place orders. What sort of considerations should I make when building a call center application. Speed is a factor here. We had a powerbuilder application that was extremly fast for a trained user. We want to have the same sort of speed in our new production system. So some thoughts I've made are: Hotkeys are important. Is it faster to use a "wizard", step by step, or should I try to place everything important about the order logically on one sceen and have another screen where you do all searches, pertinent for that order?

  • Basic use of Business Rules

    - by shinynewbike
    I have a query on whether the following requirements would need to be designed via Business Rules - this is for a JEE based application where currently this is coded as part of the Business logic. System will create a tax account for every city, county and district combination that imposes tax for only certain cities, counties or districts depending on the taxpayer's business. When the user establishes an account which exists in all subdivisions (i.e. at city or county level), the application must use his tax code and automatically populate all the locations without requiring the user to data enter every location. I assume this would mean a data lookup table from a master table (of tax accounts) and fetch and display all locations. Is there some way in which a Rules Engine can be used to manage these combinations?

  • Java Cloud Service for developers

    - by JuergenKress
    The advent of cloud computing has reinvented application development for many companies. “That’s the beauty of the cloud,” says Cameron Purdy, vice president of development, Oracle. “It dramatically improves developer productivity because they can do what they do best without having to manage complex development, testing, staging, and production environments.” The key is to find a platform that doesn’t impose proprietary restrictions or force developers to learn new tools. For example, Oracle Java Cloud Service is an enterprise-grade platform as a service for building and deploying Java EE, Oracle WebLogic Server, and Oracle Application Development Framework (Oracle ADF) applications. “It’s designed to be flexible and easy to use,” says Purdy. “And it is also a standards-based solution -it’s not proprietary and there is no cloud lock-in. Developers get instant access to an enterprise-grade environment for a simple, monthly subscription.” Oracle Java Cloud Service instances are created with just a few clicks, so businesses can create a rich application development environment within minutes. Running on Oracle WebLogic Server and Oracle Exalogic, the underlying infrastructure also leverages Oracle Fusion Middleware’s integration with common services. For example, instances come integrated and preconfigured with optimized Oracle Database and Oracle Identity Management configurations. Based on Oracle Enterprise Manager, the Oracle Java Cloud Service console lets customers easily manage and monitor their Oracle Java Cloud Service instances. The open nature of the Oracle Java Cloud Service lets developers integrate through Web services such as SOAP and REST APIs, as well as use their favorite developer tools, whether they are out-of-the-box tools such as Maven and Ant or the productivity features built into Oracle JDeveloper, Oracle Enterprise Pack for Eclipse, or NetBeans IDE. The service allows for the seamless movement of applications between on-premise Oracle WebLogic Server domains and instances of Oracle Java Cloud Service within Oracle Cloud. This approach allows flexibility to mix and match the use of on-premise environments with cloud instances for development, test, and production environments.

  • Efficient way to check for changes to the contents of folders

    - by MrVimes
    I am creating an application that maintains a database of files of a certain type in a given folder (and all subfolders) Initially the program will recurse the folders and add any file it finds of that type to the database. I want the application to have the ability to re-scan the folder and add any files that were not there the last time the folders were scanned. It can't use the date created property of the file because there is a high chance of a file being added to the folders that isn't a new file. I am wondering what the most efficient way of doing this is, and if there is a way that doesn't involve checking each file is in the database already (which, if there are 5000 files would mean 5000 queries of a list 5000 items in size, or 25 million 'checks' for the sql engine to perform) I suppose a more specific question to acheive the same goal would be - is there a property of a file (in Microsoft Windows) that will reliably tell you when that file arrived in that folder.

  • Time tracker for lxde

    - by deshmukh
    I have only recently started using lxde. And I am liking it. It is blazing fast, not-at-all resource hungry and just does what I want. The only thing I am missing is a time tracker tool. I have been using Hamster Time Tracker on gnome for quite some time. In lxde, I can still launch the application. But there are no reminders when the time limit is up, etc. The time tracker is just another window. Is there any way to get hamster working in lxde with notifications for time-up and an icon in the panel, etc.? Alternatively, is there another application like Hamster that will do all that Hamster does and WORKS in lxde?

  • OpenSource Flow Charting

    - by lazyPower
    I'm looking for an application that drops output in a portable format, maybe export as an image file so I can flowchart some application designs and submit them to my boss for professional review. From what I've seen dia is about the de-facto standard for linux flowcharting, but maybe some of you out there in askubuntu land have some other suggestions for me to examine. Please keep in mind it has to offer a professional / attractive look on the final product. Maybe some color coordination of the options (logic structures are all purple, input statements are orange... for example)

  • Pseudo-magnet implementation with chipmunk

    - by Eimantas
    How should I go about implementing "natural" magnet on a certain body in chipmunk space? Context is of simple bodies lying in the space (think chessboard). When one of the figures is activated as a magnet - others should start moving towards it. Currently I'm applying force (cpBodyApplyForce)to the other figures with vector calculated towards the activated figure. However this doesn't really feel "natural". Are there any known algorithms for imitating magnets?

  • Open .doc file from my website in browser

    - by seth
    What's the best way to give the end-user of my web application the ability to open, edit and save (via browser) word documents that are stored in my database? I have this working by doing an html conversion of the file (via Aspose Words) but this method seems not even close to flawless and i'm trying to improve this. Is integrating with google docs possible/good? Their edition seems awesome and very powerful. I can't use any Microsoft Word objects (and this is even discouraged by MS). EDIT: The application is developed in .NET and currently uses the .NET framework 2.0. However, as this is fairly obsolete the idea is to restart from scratch and therefore use the 4.0 framework and C# or VB.

  • How to make audio and video streaming servers work?

    - by Santosh Linkha
    I am PHP MySQL developer and I am interested in the way television and radio are broadcasted over Internet live. I want to know how it works and and what are its requirements (which package of which programming language offers the best). And please clarify me: Websites are stored in servers. From my desktop, if I want to broadcast some video, then I need to connect to webserver (to upstream the video). Is there an application to do that (or do I have to code that or embed in my web application and which programming language would be suitable (does Python support that))? And I also need a script to handle the upstreamed video or audio (can I do that with PHP)?

  • PPC Affiliate networks for web-applications [on hold]

    - by machete
    I want to run a browser-based social media (Twitter, Instagram,...) account management tool (justunfollow.com) which monetizes through ads. But many affiliate networks like Google AdSense or media.net require your website to have "high quality content". AdSense explicitly states: "Google ads, search boxes or search results may not be: * Integrated into a software application (does not apply to AdMob) of any kind, including toolbars. * Placed on any non-content-based page. (Does not apply to AdSense for search, mobile AdSense for search, or AdMob.)" Are there serious & trustworthy affiliate networks which allow ads to be published on a web application?

  • Does it make sense to implement OAuth for a 2 party system?

    - by nbv4
    I'm under the impression that OAuth is for authentication between three parties. Does it make sense to implement OAuth in a context where there is just a client and server. We have a server, and a client (HTML/javascript). Currently we authenticate via the normal "post credentials to server, get a cookie, use cookie to authenticate all subsequent requests" method. Will implementing OAuth be a benefit in this situation?
