• Can someone explain how a GUI works and when I should start using one?

  - by David

  I've been learning C++ for about a month now, and before I go any further, I'd like to clear up this tedious question I keep on having. I know what a GUI is, but I don't really know how it works, and maybe examples of popular ones...? Although I know command line programming is the bare fundamentals, I think it'd be fun messing around with a GUI. Although I have around 3 million other questions, I'll save them :D

• How can I increase my disk space when Ubuntu is installed alongside with Windows?

  - by Matthew

  Some time ago i reinstalled windows, formating and deleting every partition. I then made 3 partitions: One only for Windows OS (about 25GB) One for Ubuntu OS (about 25GB, if i remember corectly 10GB for swap memory and 15GB as an ext4 partition) (not sure if it was that, hope I am not wrong) and like 200GB for all the other stuff. Recently I got a message that i am running out of disk space. My question is: is there a way to resize the 200GB partition and add more space for the Ubuntu partition?

• Shutdown/logoff script in Ubuntu 13.10

  - by TNT

  Which would be the best way to run a script upon GUI logoff, shutdown, hibernate, sleep modes? In 12.04 I think I did this in /etc/lightdm/lightdm.config, but on 13.10, the folder structure changed and when I create this script, The display manager wont even start upon boot. I am looking to implement a simple automatic truecrypt unmount command truecrypt -d but of course this would go for any script.

• How can I log key presses in Game Maker?

  - by skeletalmonkey

  I'm trying to create a log of a players actions as they play a game of Spelunky. The easiest I've found to do this is to log what keys are pressed at each frame. What I don't know how to do is how to integrate this with the Game Maker source code of Spelunky. Is there a specific way to create a script that is checked every frame/tick (don't know the right term) and a command to find what buttons are pressed?

• Mount drive on remote machine

  - by NikolaiDante

  My current set up is: I have my main machine (Darkseid) upstairs which has a drive with all my films on it, which I don't keep mounted. Downstairs, next to the tv, I have a htpc (Archangel) which has xbmc installed on it, which points to a samba share on the main machine. Everything works fine when the drive is mounted, but is there a script I can write to send a command to the upstairs machine from the downstairs machine to mount the drive to save the walk upstairs? #lazy Both machines are Ubuntu 12.04

• Ubuntu 12.04 forgetting XModmap settings often

  - by PKKid

  I have the following contents in my ~/.Xmodmap file. It seems a couple times a day (without rebooting or logging out) I need to rerun the command "xmodmap ~/.Xmodmap" to reset my settings. The only thing I can think is that it seems to happen when I walk away from my computer for a bit. Maybe it forgets the settings when the computer locks itself? remove control = Control_L remove mod1 = Alt_L keycode 64 = Control_L keycode 37 = Alt_L add control = Control_L add mod1 = Alt_L Anyone else seeing similar issues?

• Can not authenticate to run GParted

  - by alfish

  Whenever I try to run a program from gnome gui, I get message Authenticated is required to run the Gparted Partition Editor The same goes for all programs that need root permission and I try to run from 'System tools' in my gnome-fallback. However the same user can become root in gnome terminal with no problem (I added the user to sudoers). I must mention that I've changed the user's password after OS install, so I think I need to update something but don't know what. I appreciate your hints.

  I have ben using 12.10 for a few days. Just upgraded it from 12.04. This comp of mine, which has a 4GB RAM and 64 bit intel processor, just goes slow randomly. When I press Ctrl+Alt+F6 and login through a command prompt, I see a number of processes using - ps -A I get many instances of a process named 'doodle' running. So many that I have to 'pkill' them by hand. Any idea why this is happening?

• update manager - insufficient storage space (false alarm)

  I'm trying to run Update Manager but it keeps reporting that there's not enough space. Here's the screenshot: I ran sudo apt-get update && sudo apt-get upgrade from the terminal but still update manager says that there are updates and I cannot seem to get pass this message. I have even removed many programs from my system and there is supposed to be at least 6GB of disk space free. What can I do?

• String or binary data would be truncated.

  This error message is relatively straight forward. The way it normally happens is when you are trying to insert data from a table that contains values that have larger data lengths than the table you are trying to insert into. An example of this would be trying to insert data from a permanent table, into [...]

• Understanding exceptional cases

  - by Justin

  I've been studying the use of exceptions in various php projects (such as Doctrine and Zend Framework). Exceptions seem to be thrown when unordinary input/state occurs. A perfect example is Doctrine throwing an exception when you try to use a invalid query string. I think the creators of the doctrine api understood that first, you can't query data by using an invalid DQL statement, and a developer should immediately be warned that an error has occurred, rather then letting execution continue with the possibility of an error code going un-checked. I also bet that this simplifies reading the code. I can't think of a situation where you would want to use an invalid DQL statement, except unit testing. Since this is true, it's better to avoid plaguing a bunch of code with null/error checks and use exceptions. I've read in books that exceptions shouldn't be thrown when validating dating user input. I've seen examples where of where the guideline is broken. One example is the Zend framework. If supplying an invalid controller or action name, an exception is thrown. Unlike doctrine, the user has more direct control over this sort of input. I know you can configure an error controller and set up a 404 message or what have you, but I'm curious why they have used an exception in this scenario? I guess you can argue the Zend Framework does not know how to continue processing the quest. One last example Is I wrote a function to return some html based on a given resource type. This resource type is hard-coded and sent when a user interacts with a web site (such as clicking a button to display the form to input data). I don't expect users to be mucking around with the request type. Under normal operating conditions, the resource type should be valid. To clean up some logic, I was going to throw an exception if a particular form wasn't found. This is mainly to find the correct form associated with a resource type so proper validation can occur. Does this sound like a valid use case for an exception? Right now it's pretty trivial, but I do plan to implement a restful consumer and re-using a function to map resources to their validation services would be very useful. I can then catch the exception and based on the consumer, return an error message suitable for the request type...

• Help identify the pattern for reacting on updates

  - by Mike

  There's an entity that gets updated from external sources. Update events are at random intervals. And the entity has to be processed once updated. Multiple updates may be multiplexed. In other words there's a need for the most current state of entity to be processed. There's a point of no-return during processing where the current state (and the state is consistent i.e. no partial update is made) of entity is saved somewhere else and processing goes on independently of any arriving updates. Every consequent set of updates has to trigger processing i.e. system should not forget about updates. And for each entity there should be no more than one running processing (before the point of no-return) i.e. the entity state should not be processed more than once. So what I'm looking for is a pattern to cancel current processing before the point of no return or abandon processing results if an update arrives. The main challenge is to minimize race conditions and maintain integrity. The entity sits mainly in database with some files on disk. And the system is in .NET with web-services and message queues. What comes to my mind is a database queue-like table. An arriving update inserts row in that table and the processing is launched. The processing gathers necessary data before the point of no-return and once it reaches this barrier it looks into the queue table and checks whether there're more recent updates for the entity. If there are new updates the processing simply shuts down and its data is discarded. Otherwise the processing data is persisted and it goes beyond the point of no-return. Though it looks like a solution to me it is not quite elegant and I believe this scenario may be supported by some sort of middleware. If I would use message queues for this then there's a need to access the queue API in the point of no-return to check for the existence of new messages. And this approach also lacks elegance. Is there a name for this pattern and an existing solution?

• BIDS Helper 1.6 Beta Release (now with SQL 2012 support!)

  - by Darren Gosbell

  The beta for BIDS Helper 1.6 was just released. We have not updated the version notification just yet as we would like to get some feedback on people's experiences with the SQL 2012 version. So if you are using SQL 2012, go grab it and let us know how you go (you can post a comment on this blog post or on the BIDS Helper site itself). This is the first release that supports SQL 2012 and consequently also the first release that runs in Visual Studio 2010. A big thanks to Greg Galloway for doing the bulk of the work on this release. Please note that if you are doing an xcopy deploy that you will need to unblock the files you download or you will get a cryptic error message. This appears to be caused by a security update to either Visual Studio or the .Net framework – the xcopy deploy instructions have been updated to show you how to do this. Below are the notes from the release page. ====== This beta release is the first to support SQL Server 2012 (in addition to SQL Server 2005, 2008, and 2008 R2). Since it is marked as a beta release, we are looking for bug reports in the next few months as you use BIDS Helper on real projects. In addition to getting all existing BIDS Helper functionality working appropriately in SQL Server 2012 (SSDT), the following features are new... Analysis Services Tabular Smart Diff Tabular Actions Editor Tabular HideMemberIf Tabular Pre-Build Fixes and Updates The Unused Datasets feature for Reporting Services now accounts for new features in Reporting Services 2008 R2 like Lookups and new features in Reporting Services 2012. SSIS: emit an informational message when a variable has an expression defined and EvaluateAsExpression = False SSAS: roles reports points to wrong server SSIS - Variable Copy / Move broken in v1.5 "Unused DataSets Report" not showing up in Context menu on VS2005 if Solution Folders used SSAS Tabular: Create a UI for managing actions SSAS Tabular: Smart Diff improvements for new schema and Tabular models SSIS: Copy/Move Variable Erroring due to custom Control Flow item Icon SSIS Performance Visualization Index out of range fixing bugs in AggManager when aggregation design IDs don't match names The exe downloads are a self extracting installer, the zip downloads allow for an xcopy deploy. Make sure to note the updated xcopy deploy instructions for SQL Server 2012.

• How do I set up a .emacs initialization file? [migrated]

  - by Harry Weston

  I am using Linux Fedora 13 (Constantine) and emacs 23.1.1. I am trying to set up a .emacs file for initialization, by using emacs itself to edit and save a file .emacs in my home directory. However, although the file is there, emacs does not seem to recognize it. What might I be doing wrong, and is there a simple text for .emacs that will show me if it is being used, one that will display a message on emacs start up?

• How to integrate ubuntu one in pcmanfm (Lubuntu file manager)?

  - by mac

  I have installed ubuntu-one on a Lubuntu machine and indeed the file syncing works for all the folder that are shared. My problem is that while on my ubuntu machine I can right click a folder and mark it as shared, I could not find a way to do the same under pcmanfm. The only workaround I was able to find is to use the daemon via command-line: u1sdtool --create-folder . which works but is kind of clumsy.... any way to integrate in the GUI?

• How to mount a drive for other user than root?

  - by Ondra Žižka

  I've attached a SSD disk though USB. Then: sudo su - mkdir /mnt/hx chown ondra /mnt/hx mount /dev/sdb1 /mnt/hx # It's FAT32 now, but was the same with EXT4 The last command changes dir owner to root. Whenever I create a file in the root dir, I need to be root and root is the owner. Can I set different user as owner of the mounted dir? Or, simply said, ensure that user XY can freely read/write on the drive.

• Still prompted for a password after adding SSH public key to a server

  - by Nathan Arthur

  I'm attempting to setup a git repository on my Dreamhost web server by following the "Setup: For the Impatient" instructions here. I'm having difficulty setting up public key access to the server. After successfully creating my public key, I ran the following command: cat ~/.ssh/[MY KEY].pub | ssh [USER]@[MACHINE] "mkdir ~/.ssh; cat >> ~/.ssh/authorized_keys" ...replacing the appropriate placeholders with the correct values. Everything seemed to go through fine. The server asked for my password, and, as far as I can tell, executed the command. There is indeed a ~/.ssh/authorized_keys file on the server. The problem: When I try to SSH into the server, it still asks for my password. My understanding is that it shouldn't be asking for my password anymore. What am I missing?
