  • Change color of Date and Weather app in Ubuntu 12.04 & Mate

    - by haunted85
    I have recentely installed Ubuntu 12.04 and as I am a truly Gnome 2 lover I also switched from Unity to Mate. The font color of the Weather/Date applet is barely visible so I was wondering how I can change it. I Already tried to explore all the options shown in the menu when I right-click on the applet, but apparently there's no such feature. So is there anything I could do in order to customize the font color in order to make the text more readable?

  • How to make my own web app

    - by pgrytdal
    After switchign to Ubuntu 12.10, I have discovered I like the Web App's feature. I do not, however, like the Gwibber application, or Twitter.com (and it's web app) because of lack of features. I do, however, like the Twitter client Hotot, but for some reason, is not working for me right now. I was wondering if there was a way I could make web.tweetdeck.com a Web App, until I can get Hotot working for me? Thank you!

  • Is perfectionism a newbie's friend or enemy? [closed]

    - by Akromyk
    Possible Duplicate: Where do you draw the line for your perfectionism? I see that the development community is very focused on doing things the right way and personally I would like to do the same too, however, is it a good or bad idea for a newbie to focus on design principles, design patterns, and commenting code when getting started, or is it better to let creativity run wild and potentially write sloppy code. Where should a newbie draw the line?

  • RTS Game Style Application [closed]

    - by Daniel Wynand van Wyk
    My question may seem somewhat odd, but I hope that my specifications will clarify EXACTLY what it is that I am after. I need some help choosing the right tooling for a particular endeavour. My background is in desktop application development and large back-end systems. I have worked primarily on the Microsoft stack using C# and the .Net framework. My goal is to develop a 2D, RTS style, interactive office simulation. The simulation will model various office spaces, office equipment, employees and their interactions with one another. The idea is to abstract the concept of an office completely. Under the hood the application will do many things that are nothing like a game. This includes P2P networking, VPN tunnelling, streaming video, instant messaging, document collaboration, remote screen sharing, file-sharing, virus scanning, VOIP, document scanning, faxing, emailing, distributed computing, content management and much more! A somewhat similar thing has been attempted by IBM, where they created a virtual office in second life. If their attempt was a game, the game-play would be notably horrible, to say the least! The users/players will drive and control my application through the various objects modelled in the simulation. A single application capable of performing all of these various tasks would be a nightmare to navigate for even the most expert user. Using the concept of a game, I can easily separate functionality by assigning them to objects that relate 1-1 with their real world counter-parts. This can greatly simplify computing for novice users, with many added benefits in terms of visibility, transparency of process and centralized configuration. My hope is to make complex computing tasks accessible to all kinds of users and to greatly reduce the cognitive load associated with using the many different utilities and applications inside office settings. The complexity is therefore limited to the complexity of the space in which you find yourself. I want the application to target as many platforms as possible and run on computers that have no accelerated graphics capabilities. The simulation won't contain any of the fancy eye-candy you find in modern games, to the contrary, my "game" will purposefully be clean and simple. The closest thing I could imagine would be an old game like "Theme Hospital" or the first instalment of "The Sims". All the content will be pre-created and not user-generated like Second Life. New functionality will be added via a plugin system. Given my background and nature of my "game", I would like to spend most of my time writing code that does not have to do with the simulated office, as the "game" is really just a glorified application menu. I have done much reading about existing engines, frameworks and tools. I need the help of an experienced game developer who has tried and tested various products over the years who can guide me in the right direction given my very particular needs. I would appreciate any help I can get!

  • Storing hierarchical template into a database

    - by pduersteler
    If this title is ambiguous, feel free to change it, I don't know how to put this in a one-liner. Example: Let's assume you have a html template which contains some custom tags, like <text_field />. We now create a page based on a template containing more of those custom tags. When a user wants to edit the page, he sees a text field. he can input things and save it. This looks fairly easy to set up. You either have something like a template_positions table which stores the content of those fields. Case: I now have a bit of a blockade keeping things as simple as possible. Assume you have the same tag given in your example, and additionally, <layout> and <repeat> tags. Here's an example how they should be used: <repeat> <layout name="image-left"> <image /> <text_field /> </layout> <layout name="image-right"> <text_field /> <image /> </layout> </repeat> We now have a block which can be repeated, obviously. This means: when creting/editing a page containing such a template block, I can choose between a layout image-left and image-right which then gets inserted as content element (where content for <image /> and <text_field /> gets stored). And because this is inside a <repeat>, content elements from the given layouts can be inserted multiple times. How do you store this? Simply said, this could be stored with the same setup I've wrote in the example above, I just need to add a parent_id or something similiar to maintain a hierarchy. but I think I am missing something. At least the relation between an inserted content element and the origin/insertion point is missing. And what happens when I update the template file? Do I have to give every custom tag that acts as editable part of a template an identifier that matches an identifier in the template to substitue them correctly? Or can you think of a clean solution that might be better?

  • How to activate a dialogue box on suspend?

    - by don.joey
    I am using 14.04 with unity. Quite regularly it happens to me that I want to shutdown the computer, but in the right corner menu I accidently hit Suspend in stead of Shutdown. Is it possible to add a dialogue box on the suspend menu? So that I don't always have to come back from suspend to finally shutdown afterwards. Or is it possible to make the shutdown button like 3 times bigger than the suspend button?

  • Implications of Cisco open-sourcing H.264? [on hold]

    - by Suman
    Cisco has announced that it will license and open-source the H.264 video codec. As a result of this, Firefox will be embedding H.264 playback functionality in future versions of Firefox. What implications, if any, will this have for programmers building software and/or hardware dealing with video (and WebRTC in particular)? (And if programmers.SE isn't the right forum, please feel free to suggest a better option.)

  • How to resize a LVM partition?

    - by iiddaannyy
    I want to shrink my second (lvm) partition, so I can create a new partition in the freespace. I am using Live-CD to do so, because I know I can't resize/move this partition while it is in use. When I opened GParted in Live-CD, I realized that I could not resize the partition, because when I right-click it, the option "resize/move" is disabled. I tried to unmount it, to "lazy" unmount it (umount -l /dev/sda2) but it didn't work. A screenshot from GParted:

  • What programming language(s) could I develop this app with for an iPhone

    - by Keon Davies
    The app I'm thinking of making would be little similar to fruit ninja. The app/ game would involve different types of animals flying straight at and you have to choose the right item to catch the animal before he gets to you. For example to capture a fish you would have to select the net and then click on the fish to capture it. Also I would like to have a leader board too. Which programming language(s) could I use to develop what I just described?

  • SQL Monitor Performance Metric: Buffer Cache Used Per Database in MB

    Data pages read from disk are placed in the buffer pool with the intention that they will be reused, and accessing them from RAM is faster than from disk. Knowing how much of your RAM is committed to each database can help you provision the right amount of RAM to SQL Server, and also to identify rogue queries that draw too much data into RAM and force data from other databases out of the cache.

  • Help with calculation to steer ship in 3d space

    - by Aaron Anodide
    I'm a beginner using XNA to try and make a 3D Asteroids game. I'm really close to having my space ship drive around as if it had thrusters for pitch and yaw. The problem is I can't quite figure out how to translate the rotations, for instance, when I pitch forward 45 degrees and then start to turn - in this case there should be rotation being applied to all three directions to get the "diagonal yaw" - right? I thought I had it right with the calculations below, but they cause a partly pitched forward ship to wobble instead of turn.... :( Here's current (almost working) calculations for the Rotation acceleration: float accel = .75f; // Thrust +Y / Forward if (currentKeyboardState.IsKeyDown(Keys.I)) { this.ship.AccelerationY += (float)Math.Cos(this.ship.RotationZ) * accel; this.ship.AccelerationX += (float)Math.Sin(this.ship.RotationZ) * -accel; this.ship.AccelerationZ += (float)Math.Sin(this.ship.RotationX) * accel; } // Rotation +Z / Yaw if (currentKeyboardState.IsKeyDown(Keys.J)) { this.ship.RotationAccelerationZ += (float)Math.Cos(this.ship.RotationX) * accel; this.ship.RotationAccelerationY += (float)Math.Sin(this.ship.RotationX) * accel; this.ship.RotationAccelerationX += (float)Math.Sin(this.ship.RotationY) * accel; } // Rotation -Z / Yaw if (currentKeyboardState.IsKeyDown(Keys.K)) { this.ship.RotationAccelerationZ += (float)Math.Cos(this.ship.RotationX) * -accel; this.ship.RotationAccelerationY += (float)Math.Sin(this.ship.RotationX) * -accel; this.ship.RotationAccelerationX += (float)Math.Sin(this.ship.RotationY) * -accel; } // Rotation +X / Pitch if (currentKeyboardState.IsKeyDown(Keys.F)) { this.ship.RotationAccelerationX += accel; } // Rotation -X / Pitch if (currentKeyboardState.IsKeyDown(Keys.D)) { this.ship.RotationAccelerationX -= accel; } I'm combining that with drawing code that does a rotation to the model: public void Draw(Matrix world, Matrix view, Matrix projection, TimeSpan elsapsedTime) { float seconds = (float)elsapsedTime.TotalSeconds; // update velocity based on acceleration this.VelocityX += this.AccelerationX * seconds; this.VelocityY += this.AccelerationY * seconds; this.VelocityZ += this.AccelerationZ * seconds; // update position based on velocity this.PositionX += this.VelocityX * seconds; this.PositionY += this.VelocityY * seconds; this.PositionZ += this.VelocityZ * seconds; // update rotational velocity based on rotational acceleration this.RotationVelocityX += this.RotationAccelerationX * seconds; this.RotationVelocityY += this.RotationAccelerationY * seconds; this.RotationVelocityZ += this.RotationAccelerationZ * seconds; // update rotation based on rotational velocity this.RotationX += this.RotationVelocityX * seconds; this.RotationY += this.RotationVelocityY * seconds; this.RotationZ += this.RotationVelocityZ * seconds; Matrix translation = Matrix.CreateTranslation(PositionX, PositionY, PositionZ); Matrix rotation = Matrix.CreateRotationX(RotationX) * Matrix.CreateRotationY(RotationY) * Matrix.CreateRotationZ(RotationZ); model.Root.Transform = rotation * translation * world; model.CopyAbsoluteBoneTransformsTo(boneTransforms); foreach (ModelMesh mesh in model.Meshes) { foreach (BasicEffect effect in mesh.Effects) { effect.World = boneTransforms[mesh.ParentBone.Index]; effect.View = view; effect.Projection = projection; effect.EnableDefaultLighting(); } mesh.Draw(); } }

  • Shut down/log out, me menu absent in panel

    - by Chethan S.
    I upgraded my Lucid installation to Maverick today via an alternate CD. Everything went fine but the shut down icon which provides the options to log out, suspend, hibernate etc. in the top right corner of the panel and the me menu which allows to set chat status are absent! I tried searching for suitable options in 'Add to Panel' but cannot find the exact solution - shut down provides option only to shut down, log out only to log out and so on.

  • Where do I put my start up script for mysql?

    - by Neo
    I have created a second instance of MySQL on the server for replication, if I start the process manually it works but need it to start at bootup. I used to just do a bash script in the init.d folder but apparently that no longer works on 11.10 Can anyone point me in the right direction? I even copied the mysql service, changed it and tried that but it refused to work. P.S It is the server edition so only Shell access.
