  • Why does sound stop working after a while?

    - by badp
    I don't know how to reproduce this problem, because I don't regularly play music or sound. All I know is that, sometimes, I'll load a video (from youtube or from a local file) and there will be no sound. Everything looks fine software wise: Rebooting always fixes. aplay, paplay and pals give no error message I'm not in the audio group, as advised The device exists and appears in use: $ lsof /dev/snd/by-path/pci-0000\:00\:1b.0 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME pulseaudi 17313 badp 23u CHR 116,10 0t0 7628 /dev/snd/by-path/../controlC0 pulseaudi 17313 badp 30u CHR 116,10 0t0 7628 /dev/snd/by-path/../controlC0 Restarting pulseaudio or alsa seems to do no good. What is wrong here?

  • Problem installing LibreOffice; please help!

    - by EmmyS
    I followed the instructions for installing LibreOffice found here, which are basically the same instructions found all over askubuntu and the web in general. I followed the instructions (including removing OO first) for gnome; all that is in my Applications menu now is LibreOffice (OO used to have OpenOffice Spreadsheet, OpenOffice Presentation, etc.) When I open LibreOffice, I get the splash screen/menu, but all of the choices for creating new docs are greyed out. It also will not open any office/type files (no errors; they just don't open.) The terminal commands indicated that installation was successful, but obviously something is missing. I'm guessing I can just reinstall OO from the software center, but I'd really like to give LibreOffice a try, given the lack of ongoing development on OO. Can anyone help me out?

  • Which features of user story management should an agile team look for?

    - by Sonja Dimitrijevic
    In my research study, I need to identify the key features of user story management tools that can be used to support agile development. So far, I identified the following general groups of features: User role modeling and personas support, User stories and epics management, Acceptance testing support, High-level release planning, Low-level iteration planning, and Progress tracking. Each group contains some specific features, e.g., support for story points, writing of acceptance tests, etc. Which features of user story management should an agile team look for especially when switching from tangible tools (index cards, pin boards and big visible charts) to a software tool? Are some features more important than the others? Many thanks in advance!

  • Render 3d object to 2d surface (embedded system)

    - by Martin Berger
    i am working on an embedded system of a sort, and in some free time i would like to test its drawing capabilities. System in question is ARM Cortex M3 microcontroller attached to EasyMX Stellaris board. And i have a small 320x240 TFT screen :) Now, i have some free time each day and i want to create rotating cube. Micro C PRO for ARM doesnt have 3d drawing capabilities, which means it must be done in software. From the book Introduction to 3D Game Programming with DirectX 10 i know matrix algebra for transformations but that is cool when you have DirectX to set camera right. I gues i could make 2d object to rotate, but how would i go with 3d one? Any ideas and examples are welcome. Although i would prefer advices. I'd like to understand this.

  • Screen dims on opening certain applications on Macbook

    - by yayu
    I have ubuntu 11.10 installed on an old 2008 macbook. There is an issue of screen dimming that I didnt find anywhere else on the forums. The issue is that the screen is dimmed when I open certain applications (Firefox, Software Center) and this cannot be readjusted by the physical brightness buttons on the keyboard. I tried a bunch of things on the barely barely visible screen, and had no choice but to restart. This has happened everytime. Does anyone know how to solve this?

  • Scheme of work contract

    - by Tommy
    I'm in the process of setting up a (one man) company and got to a item on my list "contracts and insurance". I will primary be offering custom software development but may also offer some "open source solutions", install, configure / manage e.t.c. I'm not sure how to approach a contract with a potential customer. I want to be flexible and offer the customer rights over the product (when not using open source of course) but I obviously want / need to be able to reuse code, already written and any future work. Is this possible or is it just something that people do but strictly they shouldn't? Is there a standard freelancing / contacting developer agreement? Going to a lawyer I'm sure is an answer but a very expensive one! If not do you end up with a fresh contract with each job / client and lots of trips to solicitors?

  • Can I hook my xbox up to my Ubuntu PC

    - by Anonymous John
    My old xbox 360 won't eject disks, it makes a sound,but won't open. I want to play games, so I think I could hook it up to my PC running Ubuntu 13.10 64-bit and maybe I could use my PC's DVD drive. Can this work at all, or am I just crazy? There is an HDMI port on the back of my graphics card. If I can't do that, is there any software for Ubuntu that can rip the game off of a CD and put it on a flash drive? I have heard xbmcbuntu works great for gaming, but it doesn't work with my PC.

  • Interfacing the payment systems

    - by etranger
    Hello all. I'm a complete newbie to using online payment systems for web projects, and can't really think of where to start. Let's assume that web system in question needs to generate some income online, and the business idea/functionality is in place, while organizing cash flow is the only unsolved problem. Points of interest are how the custom developed software interfaces to payment systems, and how the resulting income is available to the owner. I do understand that there are probably hundreds of systems out there, but to be more specific on which of them suit, I'd have to know how they work, and that's where I don't feel like understanding much. Thanks in advance.

  • Integrated ads in phone apps - how to avoid wasting battery?

    - by Jarede
    Considering the PCWorld review that came out in March: Free Android Apps Packed with Ads are Major Battery Drains ...Researchers from Purdue University in collaboration with Microsoft claim that third-party advertising in free smartphone apps can be responsible for as much as 65 percent to 75 percent of an app's energy consumption... Is there a best practice for integrating advert support into mobile applications, so as to not drain user battery too much? ...When you fire up Angry Birds on your Android phone, the researchers found that the core gaming component only consumes about 18 percent of total app energy. The biggest battery suck comes from the software powering third-party ads and analytics accounting for 45 percent of total app energy, according to the study... Has anyone invoked better ways of keeping away from the "3G Tail", as the report puts it? Is it better/possible to download a large set of adverts that are cached for a few hours, and using them to populate your ad space, to avoid constant use of the Wi-Fi/3G radios? Are there any best practices for the inclusion of adverts in mobile apps?

  • how to contribute the same source code to two separate open-source projects?

    - by Jason S
    Let's say there are two similar open source projects A and B, both licensed under the Apache Software License 2.0. I would like to contribute an improvement to both projects (because I don't know which one is administered better, and I would like to see my improvement show up in both). Is there a way I can contribute this improvement to both projects in a simple way? (One obvious approach is to start an open source project C licensed under Apache 2.0, but that's a headache for various reasons; I don't want to maintain a project myself)

  • Install a Mirror without downloading all packages from official repository

    - by Sam
    I first gonna explain the situation: I have a Laptop which is connected to a wifi connection, and a Desktop which can not be connected to Internet (the modem is too far from it), and i want to install some software on the last one. (The two PCs are running Ubuntu 12.04, and are connected with an Ethernet cable) I've already searched for a solution, but all I've found was the use of some softwares that should have been already installed on the "Internet-less PC". ( Keryx, APTonCD ... ) What I want to do is to create a mirror in my laptop which contain the packages i have in this one ( situated in /var/cache/apt/archive ) and i don't want to download all the packages from the official repository, I actually don't need them. Can someone tell me if it is possible to do that ? Thanks,

  • Moving from C# to Java [closed]

    - by Mike
    I worked over 5 years as C# software developer, but last time I often think, should I learn Java platform (especially Java EE)? On job sites I see that there are much more Java jobs than .NET (financial, corporate sector) and Java salaries 20-25% higher than C#. But on the opposite side I see that job count trend for C# is growing last 7 years, but Java job trend is nearly constant. Is this fact a sign that soon situation will change and C# job became more profitable? I will be grateful for any advice or your opinion! Thank you.

  • How to setup passwordless SSH access for root user

    - by Cerin
    I need to configure a machine so software installation can be automated remotely via SSH. Following the wiki, I was able to setup SSH keys so my user can access the machine without a password, but I still need to manually enter my password when I use sudo, which obviously an automated process shouldn't have to do. Although my /etc/ssh/sshd_config has PermitRootLogin yes, I can't seem to be able to login as root, presumably because it's not a "real" account with a separate password. How do I configure SSH keys, so a process can remotely login as root on Ubuntu?

  • How To Troubleshoot Internet Connection Problems

    - by Chris Hoffman
    Internet connection problems can be frustrating. Rather than mashing F5 and desperately trying to reload your favorite website when you experience a problem, here are some ways you can troubleshoot the problem and identify the cause. Ensure you check the physical connections before getting too involved with troubleshooting. Someone could have accidentally kicked the router or modem’s power cable or pulled an Ethernet cable out of a socket, causing the problem.

  • what's best language to mate with Adobe Flex-based GUI for math crunching?

    - by gkdsp
    Hi, I'm not a software expert but need to outsource a web-based scientific GUI application, and I'm considering Adobe Flex. My math routines are currently in Javascript and C/C+. Having no experience with Flex, was hoping someone could help me understand what options are available for performing (preferably fast and efficient) CLIENT-side calculations. That is, can Flex interact with Javascript and/or C easily? If not, is actionscript or other language preferred? Downsides/tradeoffs? Need functions like LOG10, LN, SQRT, and would be nice to also have the error function (ERF) and complementary error function (ERFC), although I may be able to derive these last two from more basic functions if necessary. Thanks!

  • Changing the default program for an application

    - by mohamad
    I have installed MonoDevelop and after that Wine, but when I want to open an EXE file and then double click on it, it always runs with the Mono runtime, and if I want to run it with Wine, I should right click on it and choose Wine. Well, in properties and in Open With there isn't Wine that choose it for the default application... I have this problem for all types of applications and files. When the software you want to run is in the right click application (Open With), I can't choose it in properties for the default. In fact, I can't find it in properties, because it is in open with option in right click... What should I do to fix this problem? I'm running Ubuntu 12.10 (Quantal Quetzal), 32 bit.

  • How to use driver for printer?

    - by jamie
    I've been trying to get my Lexmark x1290 to work on Ubuntu 12.04. According to this post, the z600 driver should work to print, so I downloaded the z600 driver from here and installed it through the Ubuntu Software Center. I plugged in my printer and went to the "Printer" section under System Settings... and followed the wizard to install it. It showed up as "1200-series" but never gave me a choice to choose the driver and when I try to print to it, it pops up a message that it is printing and then that it is done printing, but it is definitely not printing anything. What am I doing wrong here?

  • How a graphic designer can get into game programming?

    - by Robert Valdez
    I'm a graphic design student hoping to pursue a career as a video game artist. However, I want to do some game development as a hobby. I'd like to develop games for the desktop or mobile phones. The only programming experience I have is that I took an intro to programming with java class in which I learned how to make web applets using java's swing library. It was awful. I think the only things I took from the class was what OOP is and how to work with variables and data types and some methods. I also learned some actionscript myself which was fun unfortunately my flash tutorial expired and it's too expensive to buy;( What I was looking to do is learn one programming language and build a game with it without having to go through so many hoops and with minimum cost. If it's possible. I would love to learn C++, but I read it's not best for a beginning programmer. What programming languages or maybe software kits/platforms would you recommend?

  • Capgemini Global Business Process Management Report

    - by JuergenKress
    Welcome to the Capgemini Global Business Process Management (BPM) Report. This report is an exploration of key trends in BPM as seen by CXOs across a broad selection of sectors and geographies. BPM is perhaps at a tipping point - it’s certainly at an exciting stage in its evolution. As both an engineer and an Operational Research practitioner in my early career, and subsequently as a consultant, I have seen BPM through its development over the last 26 years. BPM has its roots in management practices such as Total Quality Management, Business Process Reengineering & Model Based Development; but the advent of the new generation of sophisticated modelling and process execution technologies has greatly enhanced BPM’s power to truly transform businesses. This has created one of the most rapidly growing and attractive market sectors for both services and technology. We see BPM as a critical management discipline that when executed against clear, cross organizational business objectives, can deliver exceptional value to that organization. However, we also see that the potential for BPM is not well understood. Our decision to conduct this global survey stemmed from discussions with our clients. We sought to gain a better impression of their understanding of BPM, how they measure its value, and how far it is prioritized within their Business and Technology Transformation efforts. This research confirms our belief that BPM needs to be a jointly owned Business and IT discipline. It also demonstrates that it is starting to gain significant traction in the market and investments are starting to pay dividends to the early adopters. At Capgemini we are being asked by our clients to help them simplify and improve their business models and the technology that supports them and we are already seeing BPM become an integral and key part of this proposition. Business Process Management is becoming ever more relevant to both large and small organizations in the current economic climate. At a time when many different market sectors are facing slow revenue growth, customer churn and increased pressures on costs, BPM becomes a critical weapon in the battle for efficiency and effectiveness in processes. Furthermore, in a challenging and changing business environment that is characterized by uncertainty, it allows organizations to adapt, be more agile and fleet of foot. Capgemini is seeing strong demand for BPM services in markets such as the USA, the UK, the Netherlands and France; and there are clear signs of increased interest in other geographies such as, Germany, Sweden, Spain, Italy and Australia. In sector terms, the financial services industry has led the way in BPM adoption over the recent past, driven by increased focus on customer- centricity and regulatory compliance. Other sectors, public sector, utilities, telco, retail and manufacturing are now not only catching up, but are starting o use BPM in new ways to create new business models to serve customers and outsmart the competition. The research findings also show however that this is a complex landscape, and we are not seeing adoption of BPM in a clear and consistent way. This report also looks at some of the barriers to adoption, with organizational silos being a major obstacle. Waters are further muddied by fragmented budgets, lack of clear governance and ownership and internal politics. The objective of our investment in this research project was to shed some light on these elements with a view to assisting organizations to create strategies that avoid or at least mitigate some of these barriers to success. Management of change in such endea vours is a key part in enabling the appropriate alignment of business and technology to support their transformation efforts. I hope that you find this report of benefit in the further adoption of Business Process Management. Get the full report here.

  • Evidence for automatic browsing - Log file analysis

    - by Nilani Algiriyage
    I'm analyzing web server logs both in Apache and IIS log formats. I want to find the evidence for automatic browsing, like web robots, spiders, bots, etc. I used python robot-detection 0.2.8 for detecting robots in my log files, but I know there may be other robots (automatic programs) which have traversed through the web site but robot-detection can not identify. So I want to ask: Are there any specific clues that can be found in log files that human users do not leave but automated software would? Do they follow a specific navigation pattern? I saw some requests for favicon.ico - does this implicate that it is a automatic browsing?. I found this article and this question with some valuable points.

  • Plan variable and call dependencies

    - by Gerenuk
    I'd like to write down the design of my program to understand the dependencies and calls better. I know there are class diagrams which show inheritance and attribute variables. However I'd also like to document the input parameters to method functions and in particular which calls the methods function executes inside (e.g. on the input parameters). Also sometimes it might be useful to show how actual objects are connected (if there is a standard structure). This way I can have a better understanding of the modules and design before starting to program. Can you suggest a method to do this software design? It should be one-to-one to programming code structure so that I really notice all quirks beforehand (instead of high-level design where thing are hard to implement without further work). Maybe some special diagram or tool or a combination? It is static dependency and call design rather than time dependent execution monitoring. (I use Python if you have any specialized recommendations).
