• 2nd instance of Firefox does not obey GTK2 customizations

  - by Cocoro Cara

  Hi On Ubuntu 10.10 I started a 2nd instance of Firefox using the command: $ firefox -ProfileManager -no-remote & Created a new profile and everything works smoothly except for the fact that this instance of FF does not obey by GTK2 customizations that I have placed in ~/.gtkrc-2.0 Moreover, only SOME of the customizations are not obeyed. For example, the vertical scrollbars are supposed to be on the left, but they are on the right. The scrollbar arrows are together (Mac-like) as specified, so is the scrollbar width. The first instance obeys all customizations with scrollbars on the left. Any ideas?

• So long wizards!

  - by geekrutherford

  In an effort to make an application more robust I have been switching to a server-side method of tracking record selections vs. client side.   The pages relying on record selections utilized the ASP.NET Wizard control which seemed like a good idea originally. Unfortunately, the design of the control is not all that flexible. It appears to want to center everything vertically which might not be a problem if it did not always use the vertical size of the largest Wizard Step for positioning.   So, I am ripping out the Wizard controls and replacing with simple Panel controls that are turned on/off. Much cleaner and presentable.

• How do I remap the buttons on an Apple Mighty Mouse?

  - by Jonathan.

  I just started using Ubuntu instead of Windows, my initial reaction was "omg this is awful", but after a while it grew on me, and I don't plan on going back to Windows. However I have an Apple Mighty Mouse which I was given today, and the buttons on it don't quite work. Left and right click work, so does scrolling right and down, also the back button works. However the forward button goes back, and the scroll up button sometimes scrolls down, scrolling left just doesn't work. Is there a way to fix this? Like remap the buttons? I'm not entirely sure how the driver thing works in Ubuntu?

• Switch Gmail Icons Back to Text Labels

  - by Jason Fitzpatrick

  If Gmail’s icon-based buttons annoy you, it’s now possible to switch them back to the old text labels with a simple settings toggle. At MakeUseOf they highlight the new option in Gmail and how you can switch back to the old button layout: So how do you make that happen? All you have to do is click on the cog button, choose “Settings”, and go to the the General tab. Scroll down to find the “Button labels” setting, and change it from icons to text.

• Browser window size statistics?

  - by Litso

  Hey all, I was wondering, are there any statistics available on what size users have their browser set to nowadays? I know the screen resolutions (we have analytics, which shows those as well) but I doubt a lot of people with 1280*xxx and higher still browse full-screen though. My boss is determined to keep our website 900px wide though, because that way people with 1800*xxx resolutions can have two browser windows next to eachother without having to scroll horizontally. I have never seen anyone browse with two adjacent browser windows like that except here at my current job, so I'm kind of doubting whether this is the best decision or just his personal preference. Anyone that can help out here?

• Are there any guidelines for laying out screen "real estate?"

  - by Corey

  I'm wondering if there is any information about creating a decent page layout so that your website will appeal to users of all resolutions. For example, the optimal width for pages. It seems like on my resolution, most websites have their content centered and covers about 80% of the page, which is easy on the eyes. Or maybe the height of the website's logo/header -- some sites I stumble upon have a huge logo with links or navigation under it, making it so that I need to scroll down to see the actual content, like articles or images (these sites don't keep me for very long). I understand that every user is different and may have browser extensions, page zoom or may be running some ancient system that displays in 640x480. I'm not looking for a "best" solution, but rather, some guidelines about designing to accommodate different resolutions. Basically, how can I make sure that I don't design a page where a paragraph might display in several easy-to-read lines on my resolution, but it turns into a single line on a 1920x1080 resolution and makes it hard for the user to follow?

• Simulating an object floating on water

  - by Aaron M

  I'm working on a top down fishing game. I want to implement some physics and collision detection regarding the boat moving around the lake. I would like for be able to implement thrust from either the main motor or trolling motor, the effect of wind on the object, and the drag of the water on the object. I've been looking at the farseer physics engine, but not having any experience using a physics engine, I am not quite sure that farseer is suitable for this type of thing(Most of the demos seem to be the application of gravity to a vertical top/down type model). Would the farseer engine be suitable? or would a different engine be more suitable?

• LWJGL glRotatef() without rotating axes?

  - by Brandon oubiub

  Okay so, I noticed when you rotate around an axis, say you do this: glRotatef(90.0f, 1.0f, 0.0f, 0.0f); That will rotate things 90 degrees around the x-axis. However, it also sort of rotates the y and z axes as well. So now the y-axis is pointing in and out of the screen, instead of up and down. So when I try to do stuff like this: glRotatef(90.0f, 1.0f, 0.0f, 0.0f); glRotatef(whatever, 0.0f, 1.0f, 0.0f); glRotatef(whatever2, 0.0f, 0.0f, 1.0f); The rotations around the y and z-axes end up not how I want them. I was wondering if there is any way I can sort of rotate just the axes back to their initial position after using glRotatef(), without rotating the object back. Or something like that, just so that when I rotate around the y-axis, it rotates around a vertical axis.

• How to change the default editor of a specific file type in JDeveloper

  - by [email protected]

  When you open a file in JDeveloper, the mode that is used as the default might not be what you as a developer want.  If, for example, every time you open a .jsp(x) file you click on the source tab at the bottom of the window so that you can edit the jsp(x) file in source code mode, you may want to consider changing the default editor for that file type.  This is easy to do in the JDeveloper tool preferences and can be a time saver in the long run, since some editors can take a while to start up and if you don't need them often, this would just be lost time.  Here are the steps:  From the JDeveloper menu, select Tools->Preferences...Select "File Types" in the tree component on the left side of the preferences dialog.Click on the "Default Editors" tab.Scroll to the file type you want to change.In the details section at the bottom of the dialog, use the "Default Editor" select list to change the default to your liking.

• Unity Particle System collision detection problem

  - by Krav

  I'm using Unity 3.5.5f3 wich has the Shuriken particle system. I've made a blood particle system based on Unity's demos. (Exploding paint [Blood]) The blood is flowing and when it collides with a Plane Transform wich I've created a small pool of blood spawns as a Collision Sub Emitter. My main problem is that when I want to add another object to collide it just doesn't want to work. When I create a cube, and set it as a collision plane the collision will only occur at the half of the cube. I want this to happen: When it reaches the cube's surface the sub emmiter activates, and when the surface is horizontal it appears horizontally, and if it's vertical then vertically. Now it just appears horizontally everytime like in the picture. How could I solve it?

• Camera closes in on the fixed point

  - by V1ncam

  I've been trying to create a camera that is controlled by the mouse and rotates around a fixed point (read: (0,0,0)), both vertical and horizontal. This is what I've come up with: camera.Eye = Vector3.Transform(camera.Eye, Matrix.CreateRotationY(camRotYFloat)); Vector3 customAxis = new Vector3(-camera.Eye.Z, 0, camera.Eye.X); camera.Eye = Vector3.Transform(camera.Eye, Matrix.CreateFromAxisAngle(customAxis, camRotXFloat * 0.0001f)); This works quit well, except from the fact that when I 'use' the second transformation (go up and down with the mouse) the camera not only goes up and down, it also closes in on the point. It zooms in. How do I prevent this? Thanks in advance.

• Reassign the Right button functionality of touchpad

  - by Guandalino

  My notebook has a touchpad with two buttons. The touchpad works pretty well and I use it for vertical/horizontal scroll, two fingers scrolling etc. The Left button acts like the left button of a mouse. The Right button too, when clicked it makes appear the classic contextual menu (create new folder, move to trash etc...). The problem is that Right button doesn't work anymore for mechanical reasons, so pressing it has no effect. To recover the missing functionality, I'd like that pressing CTRL + Left button I get the same thing of pressing the Right button alone. Other combinations (CTRL + SHIFT + Left button) are also acceptable. Any way to do that?

• Grid framework for CSS

  - by akp

  I see there are large number of grid frameworks in CSS like 960, heroku grid, etc being used by huge websites. I want to know whether using grid structure is really useful? If yes, then how? One of the biggest problem I saw with grid is having equal heights for elements. If we are using three grids like grid_2, grid_7, grid_3 for 3 vertical panels then it becomes very difficult to have these three panels positioned in a way such that they have equal heights and all of them change height when any of the content exapnds or collapse. This is because elements are floated in grid system and they don't change height along with neighbouring element.

• Is there an 'off the shelf' platform for making a new website similar to Elance?

  - by user17747

  I am interested in developing a website that is similar to 'elance' but for a particular vertical. Is there an 'off the shelf' platform you can recommend for getting started with this, or would I need to develop this web service from scratch? When I write 'platform' I am referring to things such as 'shopify' for e-commerce sites, or 'ning' for social websites. I want to create a multi-merchant professional services site. The site would need to support functionality such as: allowing merchants to open and manage their own profile. merchants would accept payments from customers through the site. file transfers between merchants and customers. merchant ratings by customers.

• Pixel alignment algorithm

  - by user42325

  I have a set of square blocks, I want to draw them in a window. I am sure the coordinates calculation is correct. But on the screen, some squares' edge overlap with other, some are not. I remember the problem is caused by accuracy of pixels. I remember there's a specific topic related to this kind of problem in 2D image rendering. But I don't remember what exactly it is, and how to solve it. Look at this screenshot. Each block should have a fixed width margin. But in the image, the vertical white line have different width.Though, the horizontal lines looks fine.

• Sentelic Touchpad Scrolling ASUS UX31 Zenbook

  - by Noel

  The capabilities of the touchpad on the new ASUS UX31 Zenbook leave much to be desired. The touchpad works like a mouse, but no vertical or horizontal scrolling. I contacted a developer who works for Sentelic. He said: Unless driver does some non-trivial works based on coordinates output, I'm afraid that it won't have scrolling support at this moment. and Windows driver does scrolling in driver where current Linux driver doesn't have such feature, yet. Additionaly, given that the resource is quite limited at this moment, I'm afraid that there is no firm schedule for scrolling support in Linux driver. How can we get this driver to do some "non-trivial works based on coordinate output"?

• Making a Background Scrolling in Stacking Game

  - by David Dimalanta

  Hmmm...Is it a good idea to use a LibGDX parallax background for making a stacking game (i.e. PAPA STACKer Lite)? For example, I'm starting to use the blocks to drag-n-drop it. Next, when the next piece reaches the top of the screen, it automatically scrolls to the next one where the available space left. Aside from that, is it also involved with the camera code (Orthographic Camera) that the screen size appeared like 720x1280 but actually it's 1440x2560 for example? And another thing, does the background scrolling have the option to scroll from start to finish and infinite?

• Non-disruptive desktop-clock?

  - by YSN

  Hello, is there a clock application, that can be placed on your screen like a widget staying always on top but automatically fades away on mouseover enabling you to click through it on items below, (behaves pretty much like the Ubuntu notifications). I am aware, that there are screenlets and gdesklets widget apps, but those are buggy, look outdated, and do not comply with the criteria listed above. What I have in mind is a clock that is large, (digital), always visible (on top of all other windows), and does not disrupt your work (e.g. you can still click that scroll bar or button if it is just below the clock, since the clock fades away on hovering). Thanks in advance, YSN

• Ubuntu 14.04 Notification incorrectly displayed

  - by xenolyse

  I have a problem with my notifications on Ubuntu 14.04 x64. The notifications are just plain text with a colored background, and are also strangely placed in the top left corner. I have no idea on how it changed. After one reboot it was just there.. Here is a picture of the problem in question.: As you can see the notification appear over the unified menu. How can I restore the original state of the notification bubble?
