  • Ubuntu 14.04 LTS AMD64 randomly uninstals packages / applications

    - by Jacob Lindeen
    I am having a strange issue. Occasionally when installing new packages, I will get a system crash notification which I will report. The environment then becomes unstable, unity crashes and all open windows, loose title bars, and the main launcher shuts down. I usually have to run the command unity --replace to restore functionality, but ultimately end up having to reboot. Upon booting back up I find all of my user-installed packages are gone and I have to reinstall them via apt. Please tell me someone else is having this issue, because this is the second system and third install I have had this issue on.

  • How to elegantly work with a lot of print functions?

    - by user1824372
    I'm working on a Python project that is executed on a terminal (or console) for which I am planning to implement a GUI. I did not major in CS so I really have no idea how to effectively design a terminal GUI such that: the user interface looks good in GUI, it is directed to a certain widget, let's say, a text label, or a bottom bar, or a hide-able frame. Do you have any suggestions? Currently, I am using the print function to provide essential information on STDOUT during execution, so a lot of print calls are distributed here and there in the code. I'm thinking of using macro-like variables such as 'FILE_NOT_EXISTS_MESSAGE' for printing, and all of them and their values would be defined in one file. Is that a standard way to do this? Should I introduce a logging system? In summary, I'm looking for a pattern for handling console output that is effective and adaptable.

  • large tmpfs /run partition - must it be so big?

    - by Stevod
    I am running Ubuntu 11.10 desktop on a couple of 8G RAM Wintel boxes. Both have been created automatically by the default installer with a 1.6GB tmpfs /run partition, where I suspect this amount of RAM could be more usefully used elsewhere in the system. I suspect that the installer takes 20% as the default, which is probably OK for boxes with lots less RAM, but seems overkill for an 8GB system. My question is - can I change its size, if so, how, and what are the risks in doing so? The /run partition does not appear in the /etc/fstab file so it must be set up elsewhere.

  • How are software projects 'typically' managed/deployed

    - by rguilbault
    My company is evaluating adopting off-the-shelf ALM products to aid in our development lifecycle; we currently use our own homegrown solutions to manage requirements gathering, specification documentation, testing, etc. One of the issues I am having is that we have what we call a pipeline, which consists of particular stops: [Source] - [QC] - [Production] At the first stop, the developer works out a solution to some requested change and performs individual testing. When that process is complete (and peer review has been performed), our ALM system physically moves the affected programs from the [Source] runtime environment to the [QC] runtime environment. You can think of this as analogous to moving some web pages from the 'test' server to the 'live' server, where QC personnel can bang on the system and complain that the developer has it all wrong ;-) Once QC signs off that the changes are working, the system again moves the code along to the next stage, where additional testing is performed, etc. I have been searching the internet for a few days trying to find how the process is accomplished anywhere else -- I have read a bit about builds, automated testing, various ALM products, etc. but nowhere does any of this state how builds interact with initial change requests, what the triggers are, how dependencies are managed, how the various forms of testing are accommodated (e.g. unit testing, integration testing, regression testing), etc. Can anyone point me to any resources or attempt to explain (generically) how a change could/should be tracked and moved though the development lifecycle? I'd be very appreciative. To keep things consistent, let's say that we have a project called Calculator, which we want to add support for the basic trigonometric functions: sine, cosine and tangent. I'm open to reorganizing the company however we need to in order to accomplish due diligence testing and we can suppose that any tools are available for use (if that helps to illustrate the process). To start things off, I think I understand this much: we document the requirements, e.g.: support sine, cosine and tangent functions we create some type of change request/work order to assign to programming coding takes place, commits are made to version control peer review commences programmer marks the work order as completed? ... now what? How does QC do their thing? Would they perform testing before closing the 'work order'?

  • Setting up the GDM Theme

    - by Szymoninho
    I'm using Ubuntu 12.04 with Gnome Classic (no effects) and because of the fact that some system options have disappeared with the new system release I've been struggling with this for a while and despite this seems very easy I can't do this :/ - does anyone know how to choose a GDM Theme? I'm quite sure that GDM is now in use on my Ubuntu - I set it up with: sudo dpkg-reconfigure gdm Despite I moved the theme folder to /usr/share/gdm/themes nothing has changed by now, I've logged out and in a couple of times but everytime I get the standard log in window and wallpaper (different from mine). So I'll appreciate any kind of help from anybody, now I have absolutely no idea how to figure it out. Cheers.

  • Even distribution through a chain of resources

    - by ClosetGeek
    I'm working on an algorithm which routes tasks through a chain of distributed resources based on a hash (or random number). For example, say you have 10 gateways into a service which distribute tasks to 1000 handlers through 100 queues. 10,000 connected clients are expected to be connected to gateways at any given time (numbers are very general to keep it simple). Thats 10,000 clients 10 gateways (producers) 100 queues 1000 workers/handlers (consumers) The flow of each task is client-gateway-queue-worker Each client will have it's own hash/number which is used to route each task from the client to the same worker each time, with each task going through the same gateway and queue each time. Yet the algorithm handles distribution evenly, meaning each gateway, queue, and worker will have an even workload. My question is what exactly would this be called? Does such a thing already exist? This started off as a DHT, but I realized that DHTs can't do exactly what I need, so I started from scratch.

  • Greenfoot project is read-only

    - by AzharHafiz.com
    I received this message when starting greenfoot on ubuntu 11.10 I'm a newbie and not sure where does the file located (greenfoot) The project is read-only.How and where do I change the permission? You will not be able to create objects or execute methods. Either the access rights of the project directory are set as 'read only' for you, or the whole file system is not writable (is it a CD?). To fully use this project, you must ensure that it is on a writable file system (usually your hard disk), and that you have write permission in the project directory and each file within it. This can often be accomplished by choosing "save as" from the Project menu after closing this dialog.

  • [AJAX Numeric Updown Control] Microsoft JScript runtime error: The number of fractional digits is out of range

    - by Jenson
    If you have using Ajax control toolkits a lot (which I will skip the parts on where to download and how to configure it in Visual Studio 2010), you might have encountered some bugs or limitations of the controls, or rather, some weird behaviours. I would call them weird behaviours though. Recently, I've been working on a Ajax numeric updown control, which i remember clearly it was working fine without problems. In fact, I use 2 numeric updown control this time. So I went on to configure it to be as simple as possible and I will just use the default up and down buttons provided by it (so that I won't need to design my own). I have two textbox controls to display the value controlled by the updown control. One for month, and another for year. <asp:TextBox ID="txtMonth" runat="server" CssClass="txtNumeric" ReadOnly="True" Width="150px" /> <asp:TextBox ID="txtYear" runat="server" CssClass="txtNumeric" ReadOnly="True" Width="150px" /> So I will now drop 1 numeric updown control for each of the textboxes. <asp:NumericUpDownExtender ID="txtMonth_NumericUpDownExtender"     runat="server" TargetControlID="txtMonth" Maximum="12" Minimum="1" Width="152"> </asp:NumericUpDownExtender>                          <asp:NumericUpDownExtender ID="txtYear_NumericUpDownExtender"     runat="server" TargetControlID="txtYear" Width="152"> </asp:NumericUpDownExtender>                                                  You noticed that I configure the Maximum and Minimum value for the first numericupdown control, but I never did the same for the second one (for txtYear). That's because it won't work, well, at least for me. So I remove the Minimum="2000" and Maximum="2099" from there. Then I would configure the initial value to the the current year, and let the year to flow up and down freely. If you want, you want write the codes to restrict it. Here are the codes I used on PageLoad:     Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load         If Not Page.IsPostBack Then             If Trim(txtMonth.Text) = "" Then                 Me.txtMonth.Text = System.DateTime.Today.Month             End If             If Trim(txtYear.Text) = "" Then                 Me.txtYear.Text = System.DateTime.Today.Year             End If         End If     End Sub   Enjoy!

  • What should be the correct ownership of /tmp /var /usr and subdirectories?

    - by sbergeron
    For some reason I think the permissions of those were messed up from a small amount of disk corruption I had. This may be a dupe, I don't know but I googled it and didn't find any mention of it. I need to know how the permissions of them should be set up as currently my computer can't actually use the tmp directory and I can't download anything consequently. I have access to the recovery mode command line but while in sudo user prompts it doesn't seem to work correctly. Also something is wrong with package management and I get dpkg: error: unable to access dpkg status area: read-only file system. I know my system is really messed up but I don't want to have to reinstall AGAIN.

  • What driver for nVIDIA GeForce MX440?

    - by ubufan
    I have recently installed (clean install) Ubuntu 12.10 on a desktop PC with nVIDIA GeForce MX440 (AGP 8x) and I have problems with Unity. Although I can see the desktop, however i can't see unity bar and icons. So, I decided to install lubuntu-desktop to see the performance. And yes! I choose lubuntu-desktop from Log On screen and the performance is definetely much better and has nothing to do with the aforementioned on unity. The system has native drivers from the Ubuntu installation. I didn't touch anything in xorg configuration. I also remember that I have managed to have the best performance with this graphic card on my previous Ubuntu 9.10 system, by editing some values in /etc/X11/xorg.conf file. But I can't remember that options, because I formatted the / partition! My question is: Which is the most suitable driver for this card, in order to load the unity feature and have better performance on it?

  • I have a performance problem

    - by Alan
    (copied from my wordpress blog). So start 95% of the performance calls that I receive. They usually continue something like: I have gathered some *stat data for you (eg the guds tool from Document 1285485.1), can you please root cause our problem? So, do you think you could? Neither can I, based on this my answer inevitably has to be "No". Given this kind of problem statement, I have no idea about the expectations, the boundary conditions, or even the application. The answer may as well be "Performance problems? Consult your local Doctor for Viagra". It's really not a lot to go on. So, What kind of problem description is going to allow me to start work on the issue that is being seen? I don't doubt that there really is an issue, it just needs to be pinned down somewhat. What behavior exactly are you expecting to see? Be specific and use business metrics. For example "run-time", "response-time" and "throughput". This helps us define exit criterea. Now, let's look at the system that is having problems. How is what you are seeing different? Use the same type of metrics. The answers to these two questions take us a long way towards being able to work a call. Even more helpful are answers to questions like Has this system ever worked to expectation? If so, when did it start exhibiting this behavior? Is the problem always present, or does it sometimes work to expectation? If it sometimes works to expectation, when are you seeing the problem? Is there any discernible pattern? Is the impact of the problem getting better, worse, or remaining constant? What kind of differences are there between when the system was performing to expectation and when it is not? Are there other machines where we could expect to see the same issue (eg similar usage and load), but are not? Again, differences? Once we start to gather information like this we start to build up a much clearer picture of exactly what we need to investigate, and what we need to achieve so that both you and me agree that the problem has been solved. Please help get that figure of poorly defined problem statements down from it's current 95% value.

  • Can I get some advice on graphics cards please?

    - by Victor9098
    I know that Steam for linux is on the way and have been seen a lot of games appearing in the Ubuntu Software Centre of late but my system lacks a decent graphics card and was hoping I could get some recommendations. The desktop is a Packard Bell Imedia S1800 (or Imedia D3526 UK) with the following specs; Memory: 3.8 GiB Processor: Pentium(R) Dual-Core CPU E5800 @ 3.20GHz × 2 The system lists the graphics as 'unknown', though I think its just an integrated Intel card From what I can see there is a free PCI-E x16 slot. Any advice would be great, thanks!

  • How can I restore /usr/share/fonts on 10.04?

    - by user207046
    I did something extremely stupid. I'm currently working on a 10.04 system (work-related), and since I was missing some fonts I decided to simply copy some over from my own, 12.10 system. I ran cp -R <12.10 root/usr/share/fonts/truetype/* /usr/share/fonts/truetype/ Immediately, terminal and window header fonts got completely messed up, although chromium still shows everything correctly, as does nautilus. How can I restore this directory? Is there anything else I have do afterwards? Thanks a bunch, Chris For shits and giggles, here's how it looks.

  • Unity does not load after update

    - by Kenpachi
    There is no unity dash or nothing after I updated my system last night. System Information : Distributor ID: Ubuntu Description: Ubuntu 14.04 LTS Release: 14.04 Codename: trusty Kernel Version : 3.13.0-27-generic And I have NVIDIA drivers 331.67 installed. I have also tried to fix this by following the advice from this post : Unity doesn't load, no Launcher, no Dash appears But no luck. In the CompizConfig Settings Manager, Ubuntu Unity Plugins is enabled, but no unity, even after a reboot. If there is a way to retrieve the list of packages which got updated the last time, please tell me so that I can post them here.
