• A way for an Upstart event to be sent whenever ecryptfs homedir mounted/unmounted?

  - by David Olivier

  I have an encrypted homedir (ecryptfs) and I'm wanting to run a private mysql daemon with the database files in my homedir. The daemon should be started whenever the homedir is mounted, and stopped before the homedir is unmounted. It seems I have to write an Upstart script, which doesn't seem too hard; the problem is triggering it. Is there already any Upstart event that is sent on these occasions? Or must I insert an "initctl emit" somewhere? Where? It seems the encrypted homedir is mounted whenever I either open my GUI session or ssh to my account. Is there a common place in these two processes where I might insert code? (I don't want to patch and compile any C code, just insert maybe a few lines somewere.) David

• Terminal Errors/Package Erros

  - by Bryan

  After running some updates a week ago or so, I've noticed that after any installations via the Ubuntu Software Center or any installed in the GUI have given an error message stating that there was a package error. Also any installations done through the terminal have given the E: Sub-process /usr/bin/dpkg returned an error code (1) message at the end of each install. Oddly, the software is still installed and seems to function properly. Is there any way to get rid of this? I've tried to run apt-get autoclean as recommended on another site, but this doesn't seem to work. I'm fairly new to Linux/Ubuntu, just FYI.

• What You Said: Do You Use the Command Line?

  - by Jason Fitzpatrick

  Earlier this week we asked you to sound off with your love (or lack there of) for the command line. You sounded off in force and now we’re back with a comment roundup. It turns out you all pretty much love the command line with that love ranging from not even liking Graphic User Interfaces (GUIs) to using the command line to get serious work done but having a long standing affair with your OS’s GUI. Many of you lamented the poor command line implementation in Windows—especially after you’d had experience with other operation systems. Mike writes: Of course. Some things are easier that was. Like ping and ipconfig. With a strong Unix background I still write and use batch files. It would be nice is the command line included more nice things like grep, sleep, touch. Maybe, someday, Windows will mature into a full OS.

• Why use apt-get upgrade instead of apt-get dist-upgrade?

  - by jimirings

  I usually use apt-get update && apt-get upgrade to run my updates and upgrades instead of the GUI because it seems to run more quickly. However, I've noticed lately that I often get a message that one of my upgrades was held back. I then usually run dist-upgrade to run it through and it works fine. As far as I can tell after reading this question and its answers, dist-upgrade does all the same things and then some. So, my question is: Why use apt-get upgrade at all? Why not use apt-get dist-upgrade all the time? Why does apt-get upgrade even exist?

• Converting 2D Physics to 3D.

  - by static void main

  I'm new to game physics and I am trying to adapt a simple 2D ball simulation for a 3D simulation with the Java3D library. I have this problem: Two things: 1) I noted down the values generated by the engine: X/Y are too high and minX/minY/maxY/maxX values are causing trouble. Sometimes the balls are drawing but not moving Sometimes they are going out of the panel Sometimes they're moving on little area Sometimes they just stick at one place... 2) I'm unable to select/define/set the default correct/suitable values considering the 3D graphics scaling/resolution while they are set with respect to 2D screen coordinates, that is my only problem. Please help. This is the code: public class Ball extends GameObject { private float x, y; // Ball's center (x, y) private float speedX, speedY; // Ball's speed per step in x and y private float radius; // Ball's radius // Collision detected by collision detection and response algorithm? boolean collisionDetected = false; // If collision detected, the next state of the ball. // Otherwise, meaningless. private float nextX, nextY; private float nextSpeedX, nextSpeedY; private static final float BOX_WIDTH = 640; private static final float BOX_HEIGHT = 480; /** * Constructor The velocity is specified in polar coordinates of speed and * moveAngle (for user friendliness), in Graphics coordinates with an * inverted y-axis. */ public Ball(String name1,float x, float y, float radius, float speed, float angleInDegree, Color color) { this.x = x; this.y = y; // Convert velocity from polar to rectangular x and y. this.speedX = speed * (float) Math.cos(Math.toRadians(angleInDegree)); this.speedY = speed * (float) Math.sin(Math.toRadians(angleInDegree)); this.radius = radius; } public void move() { if (collisionDetected) { // Collision detected, use the values computed. x = nextX; y = nextY; speedX = nextSpeedX; speedY = nextSpeedY; } else { // No collision, move one step and no change in speed. x += speedX; y += speedY; } collisionDetected = false; // Clear the flag for the next step } public void collideWith() { // Get the ball's bounds, offset by the radius of the ball float minX = 0.0f + radius; float minY = 0.0f + radius; float maxX = 0.0f + BOX_WIDTH - 1.0f - radius; float maxY = 0.0f + BOX_HEIGHT - 1.0f - radius; double gravAmount = 0.9811111f; double gravDir = (90 / 57.2960285258); // Try moving one full step nextX = x + speedX; nextY = y + speedY; System.out.println("In serializedBall in collision."); // If collision detected.

• How often is software speed evident in the eyes of customers?

  - by rwong

  In theory, customers should be able to feel the software performance improvements from first-hand experience. In practice, sometimes the improvements are not noticible enough, such that in order to monetize from the improvements, it is necessary to use quotable performance figures in marketing in order to attract customers. We already know the difference between perceived performance (GUI latency, etc) and server-side performance (machines, networks, infrastructure, etc). How often is it that programmers need to go the extra length to "write up" performance analyses for which the audience is not fellow programmers, but managers and customers?

• Technologies similar to Flash and Silverlight for Desktop apps

  - by M.A. Hanin

  Long story short: we use Flash as a partial GUI in our .NET desktop applications. Normally, this means that the Flash player control sits in some WinForm, playing a movie file. Changes in the real world are presented in the movie (e.g., a light-bulb turned on in the real world? a matching one will light up inside the Flash movie), and interaction with the instances in the movie will affect the real world (clicked the light-bulb? the light bulb in the real world will turn on). My question is: which technologies / products can offer me similar capabilities? Of course, I'm looking for something that can compete with Flash / Silverlight: animations, object-oriented scripting and design, powerful tools allowing the artists to design symbols conveniently, etc... static image objects won't cut it

• Server Controls in ASP.NET MVC without ViewState

  - by imran_ku07

    Introduction :           ASP.NET Web Forms provides a development environment just like GUI or windows application and try to hide statelessness nature of HTTP protocol. For accomplishing this target, Web Forms uses ViewState (a hidden field) to remove the gap between HTTP statelessness and GUI applications. But the problem with this technique is that ViewState size which grows quickly and also go back and forth with every request, as a result it will degrade application performance. In this article i will try to use existing ASP.NET server controls without ViewState.   Description :           When you add a server control which needs viewstate, in the presentation view in ASP.NET MVC application without a form tag, for example,            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>            It will shows the following exception,            Control 'TextBox1' of type 'TextBox' must be placed inside a form tag with runat=server             When you place this textbox inside a form tag with runat=server, this will add the following ViewState even when you disable ViewState by using EnableViewState="false"            <input type="hidden" value="/wEPDwUJMjgzMDgzOTgzZGQ6u9CwikhHEW39ObrHyLTPFSboPA==" id="__VIEWSTATE" name="__VIEWSTATE"/>             The solution to this problem is to use the RenderControl method of server control which is simply renders HTML without any ViewState hidden field.         <% TextBox txt = new TextBox();          txt.Text = "abc";          StringBuilder sb = new StringBuilder();          System.IO.StringWriter textwriter = new System.IO.StringWriter(sb);          HtmlTextWriter htmlwriter = new HtmlTextWriter(textwriter);          txt.RenderControl(htmlwriter);  %>        <%= sb.ToString() %>             This will render <input type="text" > without any View State. This technique become very useful when you are using rich server controls like GridView. For example, let's say you have List of Recalls in Model.Recalls, then you will show your tabular data as,     <%  GridView gv = new GridView();          gv.AutoGenerateColumns = true;          gv.DataSource = Model.Recalls;          gv.DataBind();         StringBuilder sb = new StringBuilder();         System.IO.StringWriter textwriter = new System.IO.StringWriter(sb);         HtmlTextWriter htmlwriter = new HtmlTextWriter(textwriter);         gv.RenderControl(htmlwriter);%>            <%= sb.ToString() %>             This code might looks odd in your presentation view. A more better approach is to create a HTML Helper method which contains the above code. Summary :        In some cases you might needs to use existing ASP.NET Web Forms server controls but also dislikes ViewState. In this article i try to solve this gap by using the RenderControl method of Control class. Hopefully you enjoyed and become ready to create HTML helpers for many of the existing server controls.

• Creating an installer for a python GTK3 application

  - by Noam Gal

  I have just finished developing a Python 2.7 application using Gtk3 for GUI. My question is, how can I now create an installer for Windows, Mac, and Linux (possibly three different installers) for my end-users to easily download the application without having to download python and GTK and such. I have never created an installer from a python script before. I have heard that are some tools for this purpose (py2exe? pyinstaller?), but I wouldn't know how and what to pack with them in order for it to be able to use Gtk3. Thanks in advanced, Noam.

• Unity Android: Truecolor texture performance hit and alternatives for truecolor

  - by Esa

  After integrating the graphics assets to my application, I noticed that when the textures are compressed they look very bad compared to truecolor. This happens to all the textures and it did not seem to help changing the texture type to GUI nor did it help to switch the 32-bit display buffering on. Does using truecolor textures make the application much heavier to run? Or does it just increase the size of the .APK? Are there alternatives to getting a good texture quality and a smaller texture size instead of using truecolor?

• Can Unity be uninstalled?

  - by Dave M G

  Recently when doing an update, I noticed I was downloading a bunch of packages related to Unity. I use Gnome-Classic, and have no intention of ever using Unity. So, I thought I might save myself some bandwidth and download times (which can be slow on my laptop) by removing Unity. However, on next reboot, I could not get any form of GUI interface. Only by reinstalling Unity was I able to get the log in interface and get back into Gnome Classic. Can I get rid of Unity, or is it somehow now integral to Ubuntu in a way that makes Ubuntu not run without it (even if I'm exlusively using Gnome-Classic)?

• How to check the information of current installed video drivers on Ubuntu?

  - by smwikipedia

  Hi guys, I have just installed Ubuntu 10.04. My CPU usage is high when I do trivial things such as scrolling through a PDF file. So I think my video driver is not properly installed. I want to confirm that by checking the information of my currently installed video driver, such as if there's a driver installed and what version it is. Then I could decide whether to install a new one if it is not up to date. On Windows, I could use the device manager, how to do that on Ubuntu Linux? I don't expect a GUI solution for this. Command line will be just good enough. Many thanks.

• Can't ping Ubuntu laptop from my LAN

  - by oskar

  My laptop has Ubuntu 10.10 and is connected to my router with full internet access, yet I can't ping it from other computers on my LAN. I tried the following: I can successfully ping those other computers from my Ubuntu laptop, so I didn't accidentally connect to someone else's network. I can successfully ping my Ubuntu laptop from itself, though I don't know if that means anything. I haven't messed with iptables at all, so it currently doesn't have any rules set that would cause it to reject anything. I made a DHCP reservation for my laptop's MAC address in my router to make sure I was always using the correct IP address. Please note that I am using a "command line only" install of Ubuntu, so I can't use any GUI network config tools. The reason I want to ping it is because I am trying to run an NFS server on the laptop, yet despite correctly setting it up I cannot access the NFS volume on another computer because it isn't even visible on the network right now.

• Is it worth learning either GWT or Vaadin?

  - by NimChimpsky

  I consider myself a decent java/web developer. In my career I have always used servlets and ejb's with a web front end, most recently incoporating jquery and ajax. I can see the theoretical benefit of using GWT or Vaadin: it is my understanding they convert Java code to the required JavaScript/HTML. So the developer gets the benefit of cross browser compatibility and compile time error checking (of web GUI elements). My question is threefold: Are there any other benefits I am missing that would be gained using Vaadin or GWT? I am actually quite confident and productive using HTML and JavaScript - so will I actually see any benefit? Or will it just make my knowledge of these areas redundant (as they are handled by GWT/Vaadin)? Will the end result be that I can create enterprise scale data driven websites in a reasonably short time? I can however already do this, and I have not wasted any time learning GWT/Vaadin.

• How are Programing Language Designed?

  - by Anteater7171

  After doing a bit of programing, I've become quite curious on language design itself. I'm still a novice (I've been doing it for about a year), so the majority of my code pertains to only two fields (GUI design in Python and basic algorithms in C/C++). I have become intrigued with how the actual languages themselves are written. I mean this in both senses. Such as how it was literally written (ie, what language the language was written in). As well as various features like white spacing (Python) or object orientation (C++ and Python). Where would one start learning how to write a language? What are some of the fundamentals of language design, things that would make it a "complete" language?

• Beyond Syntax Highlighting - What other code representations are possible today?

  - by Mathieu Hélie

  Despite GUI applications having been around for 30ish years, software is still written as lines of text instructions, for various valid reasons. But we've also found that manipulating these text instructions is mind-blowingly difficult unless we apply a layer of coloring on different words to represent their syntax, thus allowing us to quickly parse through these text files without having to read the whole words. But besides the Sublime Text minimap feature, I've yet to see any innovation in visual representation of code since colors came around on CRT monitors. I can think of one obviously essential representation that modern graphics technology allows: visual hierarchies for nested structures. If we make nested text slightly smaller than its outer context, and zoom on it when the cursor is focused on the line, then we will be able to browse huge files of nested statements very quickly. This becomes even more essential as languages based on closures and anonymous functions become filled with deep statements. Has anyone attempted to implement this in a text editor? Do you know of any otherwise useful improvements in representing code text graphically?

• What is so good about Linux? [closed]

  - by Chris Bridgett

  Self-explanatory question title. I've only ever used Windows OS's (except Mac OSX at friends etc, years ago occasionally) and when diving into the world of programming, Linux is a name that is coming up every other tutorial or article. All my web hosts run Linux and a lot of programming literature covers how to go about various tasks on Linux as well as Windows, but other than the odd raving I've read years ago about Linux being less resource-intensive, I haven't really given it much thought. Any article I read about Linux and whether it should be used for... 'regular' use, it's shunned since any windows applications I'm familiar with will usually require the windows API and there's no end of 'hacking' to get various programs working on Linux. As far as I understand a GUI is optional on Linux too? This all sounds very noobish I'm sure, but we all start somewhere, so: What is Linux good for? What should Linux be used for?

• Security of keyctl

  - by ftiaronsem

  Hello alltogether Today I set up an ecryptfs directory, which is automatically mounted at login via pam. To do so i followed the guide in the ecryptfs readme ecryptfs-readme To sum up, I now have a key stored in the usser session keyring. The first thing I do not understand is why this key is only showing up via keyctl show and not with the gnome-gui "Passwords and encryption keys". The second thing I am curious about is the security. I assume that my passphrase is somehow stored on the harddisk. But how exactly and how secure is this? Thanks in advance

• How to mount a disk that supports Samba sharing (Using Disk Utility)

  - by Luis Alvarado - The Wolverine

  This might be a tricky question but here is the objective: Manage to mount a disk/partition automatically without (or at least trying to avoid): Editing any Samba configuration file Editing the fstab file and to make it a little bit harder, this needs to be done with the options for "Mount Options" in the Disk Utility: Note that if left as it is, every time a user mounts a partition/disk and then tries to share a folder in it, Windows users can see the share but can not access it, with a permission warning appearing. The point of all of this is to find the most user friendly (Oriented towards a GUI) way of enabling a partition to be mounted, accessed by the local user (Read, Write, Execute) and to also be able to, when needed, share a folder and have no problems reading/writing on it from another Ubuntu/Windows/Mac remote computer (Assuming both are in the same LAN network).

• Partial upgrade error

  - by Dan

  this is an issue I have googled a lot and I have tried a lot of fixes, but non of them really worked. At some point (I can't remember when/how) my Update system sort of broke, and since then it is always complaining about "Not all updates can be installed, run a Partial Upgrade". If I click on Partial Upgrade, I get the following result But running apt-get install -f does not fix anything, and at the end I always get the following message Funny thing is that my apt-get system works perfect on Console. I can update my system through apt-get update, apt-get upgrade etc.. So.. how can I fix the graphic interface? I understand that my apt-get system is not broken, but somehow its GUI it is. Any thoughts about it? THANKS! P.D: I have already tried sudo dpkg --configure -a and sudo apt-get autoremove

• How to change/create password keyring

  - by sadmicrowave

  when I try to remote desktop to the server from another ubuntu machine using the remote desktop viewer, it asks me to enter the password, which I do, then the viewer pane just goes black. When I come back and look at my server it is saying that the password keyring no longer matches the password used to login to the machine please reenter the password...and when I type in the password it doesnt take it, it just keeps popping back up saying the same message over and over. I found a thread explaining to go to System--Preferences--Passwords & Encryptions and right click on the keyring and click Set as Default. I did that and the problem persists...I tried changing the password but it told me that my original password was incorrect (even though it is the password I use to login and provide root authentication when asked) so I deleted the keyring in hopes of adding a new one but there is no place in gui to add a new one...so can I add a new one through command line? if so - how?
