  • How do I detect when my system wakes up from suspend via DBus or similar in a python app?

    - by con-f-use
    In a background Python script I need to detect, when the system just woke up from suspend. What is a good way that does not rely on a root script but rather on python modules such as DBus? I'm new to dbus so I could really use some example code. From what I read it's related to org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.Resuming Can anyone help me out with some code that connects the resuming signal to callback?

  • The battery indicator in Unity panel not showing up

    - by user61415
    I installed Ubuntu 12.04 with Wubi. Well after being completely dazzled with the amount of free content in the Software Centre, I decided to go deeper and start messing with settings. Well after changing the screen brightness the highest level I noticed that there wasn't an indicator for how much battery was left in my laptop. I looked up online on got 2 suggestions on how to fix: Right click on the Unity panel and add an indicator Set it to show in the power settings menu. Well I did both when I right click at the top menu nothing comes up and setting it to show does nothing either. Then I tried installing something in the Software Centre. I got something but when I activated it it said I had 0% power left even though I was charging and at %100 according the Light in the front of my laptop. So now I'm thinking that it doesn't even recognise my computer as a laptop which is weird because in the display settings it says my screen size is set to laptop. How can I install it? I don't know what version it is other then Ubuntu 12.04 and no matter what the icon does not appear with the

  • What should I do when the GETDEB repository is down?

    - by 13east
    I'm trying to install programs/files from the getdeb repo but get a "check your internet connection" error. Programs than I've tried include Qbittorrent and Mozilla-Plugin-VLC.

  • What best practices exist to avoid vendor lock-in?

    - by user1598390
    Is there a set of community approved rules to avoid vendor lock-in? I mean something one can show to a manager or other decision maker that is easy to understand and easily verifiable. Are there some universally accepted set of rules, checklist or conditions that help detect and prevent vendor lock-in in an objective, measurable way? Have any of you warned a manager about the danger of vendor lock-in during the initial stages of a project?

  • Xfce Power Manager on Xubuntu 13.10 doesn't work

    - by kirokko
    The problem is that its actually works, but something works with Xfce Power Manager at the same time. For example, I set that if I pressed Suspend button (on my Lenovo B560 its Fn+F2 hotkey) then system ask me what to do. But when Log out window appears, system goes to suspend. Another example is closing the lid. I set it to lock the screen via Xfce Power Manager, but system still goes to suspend. I thought that it might be laptop-mode-tools, but it's not installed. Before 13.10 I had 13.04 and everything were fine.

  • “Can You See Me Think?”

    - by andyleonard
    Introduction This post is the fifty-seventh part of a ramble-rant about the software business. The current posts in this series can be found on the series landing page . A Story… Once upon a time I was a manufacturing systems integrator. That’s a fancy description of a person who designs and builds machine control systems. I was asked to replace a control system and given a tight timeline to accomplish the work. My engineering spidey-senses were tingling, but there were bills to pay and the promise...(read more)

  • Installing Solaris Studio 12.2?

    - by KronoS
    I'm having a dickens of a time installing Solaris Studio 12.2 on Ubuntu 10.04. I found this guide, however using the alien option isn't finding the correct files. I'm not exactly sure on the syntax of alien, its kinda alien to me. (sorry for the bad pun) Also, when I download the tar file, and extract it, there are errors everytime saying things like: "operation not permitted" cannot creat symlink to '../prod/bin/cc': Operation not permitted I've extracted with super user access, but to no avail. Any success from anyone else?

  • How do I remove a malformed line from my sources.list?

    - by eminencejae
    I have unistalled and reinstalled the Ubuntu Software Center as per info I found in a similar thread and I got the same response about line 91 or something like that. I just tried to upload a screen shot but since I'm new it won't allow me to. I also can not figure out how to cut and paste anything so I have to hand type what the error screen says, both when I attempt to open the software center and nothing happens, when I try to enter commands into the terminal to uninstall, reinstall, whatever I get the same following: COULD NOT INTITIALIZE THE PACKAGE INFORMATION An unresolvable problem occured while initializing the package information Please report t:his bug against the 'update-manager' package and include the following error message: 'E: Malformed line 91 in source list/etc/apt/sources.list (dist parse) E: The list of sources could not be read., E: The package list of status file could not be parsed or opened. How do I report bugs? What can be done about this. I have searched and everything everyone says to do leads me back to the same line error message. So, I don't know how to get to line 91 in the source list; to tell you what it says. Sorry, I'm really new to this. That is what I need is to find out how to get there and fix what it says. I would really like to NOT have to re partition my hard drive and start from scratch, so I'm really looking forward to getting this problem solved. I need to be able to install new software.

  • How to obtain a list of installed packages based on a backup?

    - by ujjain
    I have made a backup of my entire computer and I reinstalled the OS right now. I know I should have listed dpkg -l to obtain a list of packages, but I have not done so. I only made a tarball of the entire disk. I wonder how I can find a list of packages based on this data. I would like to have the same packages installed that I had on my previous set-up. But there seems no longer a way to gain a list of packages, since I already reinstalled Ubuntu on the computer and only have the tarball back-up.

  • Requirement, architecture data capture tool

    - by Deno
    Are there any tools available for the following use case: I am planning to write a complex application and now I just know about the basic functional requirments. I am refining the functionality with more and more details. I am also writing down how to implement this in software architecture perspective. I am in a situation where there are multiple ways implement a certain functionality and based on the selected approach, other parts of the program will also change. At this moment, I don't want to decide on the approach to use, I just want to list down all the options, present to a wider audience and get it finalized. Are there any standard software tools to do this? I know I can use MS excel or some mind mapper tools, but just thinking of some standard tools (not just for programmers, but for managers and other) availability Thanks, Den

  • Should one reject over-scoped projects?

    - by Little Child
    I spoke to my first potential client today and he told me about the requirements of his project - an Android app. He is a well-known designer / photographer in my country and now wants me to "convert the website into an app, custom-tailored". So the requirements, details stripped out, are as follows: eCommerce Aggregating all his content like videos, blogs, tweets, etc. into the app Live streaming any of his studio demos Augmented reality. So that people can see what his painting will look like on their wall before they buy it Taxi Sharing Now, for a freelance project, it seems too over-scoped. I am not saying that I cannot do it. I can. But let me be realistic: There is a steep learning curve when it comes to VR. I am not a tester. I have never white-box tested my own apps. I always black-box test. Since he is a renowned artist, something short of perfect might harm his public image So, I asked him for 2 weeks' worth of time before I give him the final answer. Now knowing whom to consult for advise, I am posting the question here. Although interesting and personally challenging, I am split-minded about accepting a project like this. I will be the only developer for this. Should one reject a project that seems to be over-scoped for one's own abilities?

  • How and when is old-releases.ubuntu.com updated?

    - by muru
    The old-releases.ubuntu.com mirror hosts the repositories for EOL Ubuntu releases. The main page currently lists up to 11.10 (or 12.04.3 if you count point upgrades), but the dists page lists up to 13.04. Why the discrepancy? When will the main page be updated? When will the newest EOL release (13.10) be shifted here? I'd like documentation backing up answers, please. Priority of documentation: Statements by Mark Shuttleworth (on his blog or other public statements) Pages from the Official Ubuntu documentation Ubuntu mailing list discussions, Launchpad bug reports (or questions) or blueprints, etc. IRC discussion logs for official Ubuntu channels Random gossip on the street Community Wiki.

  • Long term planning and agile?

    - by Ignite
    My team has recently went through the process of laying out a nearly one year plan for our direction of work. We have separated the plan into three phases and each phase will include a couple of launches. I wonder, from an agile point of you, is what we do wrong? I think it's not a bad idea, because we haven't spent too much time on designing anything but the first few steps and it's possible for us to change direction. At the same time it's nice that we don't act with only the near term in sight.

  • Has an open console any chance to give more strength to the indie game world ?

    - by jokoon
    I have heard about the GPX, but i don't really think the embedded market is mature enough in terms of performance, but what about the home console market ? I'm not talking about last-generation graphics, because that would be economically impossible, but what about an hardware as fast as a playstation 2/Xbox 1/Gamecube ? For games, the trick would be to ask some editors to recompile their best sellers for the new machine: those games being from the PSX age or even older console generations, I think this would have a very low cost job and they could still make some good profit, but I need to know if this is doable technically, considering the architecture which can be quite exotic. Do you think it would be a viable project to talk about to investors ?

  • Reboot only shuts down and doesn't actually boot again

    - by PherricOxide
    I'm running a fresh install of Ubuntu 12.04 Server on an abmx rack mount server. When I attempt to reboot with sudo shutdown -r now, the machine just shuts down and doesn't come back up without me manually pressing the power button. The output of last -x, runlevel (to lvl 2) 3.2.0-29-generic Wed Oct 31 14:32 - 14:37 (00:05) reboot system boot 3.2.0-29-generic Wed Oct 31 14:32 - 14:37 (00:05) shutdown system down 3.2.0-29-generic Wed Oct 31 14:30 - 14:32 (00:02) runlevel (to lvl 6) 3.2.0-29-generic Wed Oct 31 14:30 - 14:30 (00:00) This appears to show that the system rebooted, but it went dark (no power lights, BIOS, etc) and I had to go press the power button in order to make it boot back up. The machine does have some sort of Intel Boot Agent that usually appears before the BIOS, I'm wondering if it could be causing this. I'm not sure what information is useful for debugging this, but I put the output of lshw in http://pastebin.com/mBy72kTQ

  • "The volume filesystem root has only..."

    I am having this problem in ubuntu 12.04, but I fin strange that when I go to /tmp it wont allow me to delete some files, with message "Operation not permitted" or "this file could not be handled because you dont have permissions to read it". It is only a PC and I have the root password. I was trying to get at least 2000 MB of free space on the root file system to upgrade to 12.10 and see if that resolved the problem.

  • Kickstarter and 2D smartphone games

    - by mm24
    I am about to launch a Kickstarter project as, after 14 months of full time development on my first iOS game, I run out of money. I developed an iOS game that needs few more months to be ready (the game structure is there but haven't yet worked on balancing the difficulty of the various levels). I have a feeling that most of the computer games founded on Kickstarter are for console, PC or Mac and not for smartphones. The category that many people seem to like is RPG style games. I have done tons of work over a year and collaborated with musicians and illustrators to get top quality graphics and music. The game looks cool to be an iOS 2D game but, compared to what I've seen on Kickstarter, I feel so little and humbled. I have searched for smartphone game projects on Kickstarter but haven't found many. I believe that the reason is that people are not keen in backing an APP that is normally sold for 0.99$ as they perceive is not something big. Am I the only one having this feeling? Could anyone please share a list of references to some successfully backed kickstarter smartphone game projects? (In this way the question will not become a "chat" and will fulfill the requirements to be a gamedev question). Any other article or authoritative answer will be welcome.

  • Is there a name for this use of the State design pattern?

    - by Chris C
    I'm looking to see if there is a particular name for this style of programming a certain kind of behavior into a program. Said program runs in real time, in an update loop, and the program uses the State design pattern to do some work, but it's the specific way it does the work that I want to know about. Here's how it's used. - Object Foo constructed, with concrete StateA object in it - First loop runs --- Foo.Run function calls StateA.Bar --- in StateA.Bar replace Foo's state to StateB - Second loop runs --- Foo.Run calls StateB.Bar - Third loop runs --- Foo.Run calls StateB.Bar - Fourth loop --- etc. So in short, Foo doesn't have an explicit Initialize function. It will just have Run, but Run will do something unique in the first frame to initialize something for Foo and then replace it with a different action that will repeat in all the frames following it- thus not needing to check if Foo's already initialized. It's just a "press start and go" action. What would you call implementing this type of behavior?

  • Hibernation is still missing from menu in 13.10 after enabling via polkit. How to enable?

    - by LiveWireBT
    I know that since 12.04, we need to add a policykit rule to enable hibernation (see question How to enable hibernation? and the Official Documentation). I can successfully bring my laptop into hibernation mode with sudo pm-hibernate or sudo s2disk, so the rule is in place and works, but the hibernation entry is still missing in the menu. I can tell from looking through the source of the indicator-session package (but not understanding the whole code) that there is still a hibernation menu entry in the code and it should be displayed when the system is capable of hibernating. Please calm down if you're enraged by this. This is very unlikely to be a conspiracy, but rather a bug/regression on a deeper level, which can happen when you move code around or replace it. Question: What needs to be done in 13.10 to properly tell indicator-session that the system can hibernate? Possible duplicate: Hibernation still not available - No activity, because saucy was in development at that time, so out of scope for AskUbuntu. Related bug report: https://bugs.launchpad.net/ubuntu/+source/indicator-session/+bug/1232814

  • How to speed up rsync/tar of large Maildir

    - by psusi
    I have a very large Maildir I am copying to a new machine ( over 100 BaseT ) with rsync. The progress is slow. VERY SLOW. Like 1 MB/s slow. I think this is because it is a lot of small files that are being read in an order that essentially is random with respect to where the blocks are stored on disk, causing a massive seek storm. I get similar results when trying to tar the directory. Is there a way to get rsync/tar to read in disk block order, or otherwise overcome this problem?

  • What is an effective way to organize tasks for a new project?

    - by Dulan
    Is there a practical solution to organizing the initial tasks for a new project? To elaborate, imagine the features/stories/goals are laid out for a project. How might one go about organizing those into sane tasks for the first few versions? The scenario I typically have in mind has the features listed as a high-level reference for what the end user-experience should involve. The tasks for constructing such features are then broken down into chunks (such as "create interface for X component"). Such a task is not necessarily "tied" to only that feature and may be useful when building subsequent features. Is breaking features down into small, code-able solutions valid? Or should they be slightly removed from any specific implementation? I do not expect that there is one "right" answer to this question, but I am looking for a fairly pragmatic and unobtrusive approach. As a note, I'm looking for solutions that are independent of any tools or "systems" used for managing the tasks themselves.

  • Power manager keeps shutting down the display

    - by david25
    I'm probably missing something here. I'm using the default Ubuntu power manger, I set it up like this: On AC: no screen dimming when idle, never put computer to sleep, never put display to sleep. On battery: I kept the default settings. Still, Ubuntu does whatever it likes, and after 15 min it puts the display to sleep. Does anyone have the same problem and found a way to solve it? I'm using an Eee PC with Ubuntu 10.10 Desktop.
