• How to tweak the appearance of desktop icons in Lubuntu?

  - by vasa1

  In Ubuntu 11.10 with Nautilus it was possible to tweak the appearance of desktop icons by editing nautilus.css as I had posted in How can I change the text colour on my desktop icons?. In Xubuntu the same can be done by adding a few lines to one's .gtkrc-2.0 as described in How to highlight items on Desktop using xfce?. In both cases, it is possible to assign colors to the various icon states (such as normal, selected and active). My question is this: is it possible to do the same in Lubuntu? PCManFM seems to be responsible but I can't find any GUI or files to edit for the purpose. The default ~/.config/pcmanfm/lubuntu/pcmanfm.conf doesn't have any relevant settings.

• Taking web sites offline for demonstration on iPad

  This article is the iOS sequel to the initial article about how to prepare an offline version of your web site for the purpose of demonstration or for exhibitions: Taking web sites offline for demonstration.

• How To Change the Default Search Engine in Windows 8's Internet Explorer 10

  - by Chris Hoffman

  You can change the default search provider in the Modern version of Internet Explorer 10, but Microsoft hides this option well. You won’t find it in IE’s Settings charm – you’ll have to change this setting from the desktop. After you change this setting on the desktop, both versions of Internet Explorer will use your preferred search engine. You’ll have to use the desktop to change certain settings on Windows tablets — even Windows RT includes a limited desktop. 6 Start Menu Replacements for Windows 8 What Is the Purpose of the “Do Not Cover This Hole” Hole on Hard Drives?

• Where to get PNG icons/graphics for game development for kids? [closed]

  - by at.

  Possible Duplicate: Where can I find free sprites and images? I'm teaching kids to program using Ruby and the gaming framework Gosu/Chingu. Kids love it, including the part where they have to look for the icons/graphics for their game objects. I direct them to iconarchive.com, but the selection is sometimes very limited, the graphics aren't always with transparent backgrounds and sometimes the art requires payment. I don't mind paying for an educational license of some sort, but I want the kids to easily select graphics they can use in their games. Is there another resource better suited for this purpose? I don't have a good solution for this, but would also love a site they can get cool background images for their games.

• Sony VAIO wireless card not connecting intel 4965AGN

  - by marcski55

  I'm running a Sony VAIO VGN-CR410E, and recently moved it to Ubuntu from Windows 7. Both my home and work networks (which I maintain) run WPA/WPA2-PSK authentication for security. My wireless network card (intel 4965AGN) will not connect to them unless I am in the same room (kind of defeats the purpose of wireless). The PC is 4 years old and the routers are brand new (last month or so). Had no problems with it with Win7, but Ubuntu just doesn't like the networks. As an IT manager, my laptop needs to work, so any help is appreciated. If this is a duplicate, please let me know of what. I've spent hours searching and nothing has worked. Thanks for your help. (This is my first experience fully relying on Ubuntu). I can see the networks and attempt connection, but it fails authentication. Let me know of any code you need.

• Rules of Holes -#2: You Are Still in a Hole

  - by ArnieRowland

  OK. So you followed the First Rule of Holes -you stopped digging yourself in deeper. But now what? You are still in a Hole. Your situation has not changed much, but at least you are no longer making it worse. You need to redirect the digging effort into escape and avoidance efforts. The Hole has a singular purpose -consuming all of your time and effort. AND it has succeeded! But now you are going to redirect your efforts for your own survival. You need to look around, take stock of the situation....(read more)

• Free Models and Related Animations for AI project in Unity [on hold]

  - by zhed

  Does anybody know a good website where to find free models and animations for AI projects? I'm not talking about anything good looking, like stuff you would look for when building a proper game, but, for example, a bunch of male/female models that are able to walk around and that would substitute my ugly "capsules", just to give a better -yet, still rough - idea of what's going on in the scene. On the Unity Asset Store there are a bunch of nice male/female models, but i haven't found any free general-purpose(i.e. normal walking) animation attachable to them. Any tip would we appreciated, thanks :)

• Online job application

  - by Fred

  I am trying to add an application to my site where I can post job openings with my company and allow people to apply online. Can someone recommend a service or app already in existence for this purpose? I tried googling it, but could not find a set of search terms that did not return endless sites for job seekers. This is a (very) small business and I do not expect to have more than a few openings at any time, but what I am actually interested in is having a repository of interested job seekers to have on file. Then when people ask me about openings, I could just refer them to the page and they could apply. Then, if we have an opening, we could look through the list of candidates and if we can't fill the position(s) from that list, we could post the job and advertise to fill the position.

• Check for Instant File Initialization

  Instant File initialization, IFI, is generally a good thing to have. Check out this earlier blog post of mine f you don't know what IFI is and why it is a good thing: blog . The purpose of this blog post is to provide a simple script you can use to check if you have IFI turned on. Note that the script below uses undocumented commands, and might take a while if you have a large errorlog file...

• How to achieve 'Activities' in Unity?

  - by Ralf Hersel

  I like the concept of an activities centric desktop and I wonder if this can be achieved in Unity. For me, an activity is a couple of applications that belong to the same subject, like 'photo manipulation', 'software development', 'office work', 'social activities', 'music and video'. I would like to utilize the virtual desktops to arrange applications that belong to the same activity group. Example: Desktop 1 contains all applications that belong to 'office work' Desktop 2 contains all applications that I need for 'software development' Desktop 3 contains all applications that I usually need for 'photo works' Therefore I would like to give names to the virtual desktops that reflect their purpose. And I would like Unity to auto-start the required applications when I start my computer or when I switch to one of the virtual desktops. Is this possible with Unity (or any other desktop)?

• Should I implement an interface directly or have the superclass do it?

  - by c_maker

  Is there a difference between public class A extends AbstractB implements C {...} versus... public class A extends AbstractB {...} AbstractB implements C {...} I understand that in both cases, class A will end up conforming to the interface. In the second case, AbstractB can provide implementation for interface methods in C. Is that the only difference? If I do NOT want to provide an implementation for any of the interface methods in AbstractB, which style should I be using? Does using one or the other have some hidden 'documentation' purpose?

• Are there Any Concerns with Importing Document Files From a Competing Product?

  - by Thunderforge

  I have a new product that serves the same purpose as my competitor's long-standing product. One thing I have considered doing is allowing my program to import document files created by their product in order to provide an easy way for users to migrate towards mine. Naturally, this would be done without the competitor's permission, as it goes against their interests. I've seen this done before with office suite software (e.g. Open Office and Apple Pages can import MS Word documents), but I'm wondering if there are any concerns, legal or ethical, with me doing this. I fully expect any answers will most likely fall under the "I am not a lawyer" clause, but it would be helpful to have a starting point for anything I would need to be aware of, or if I shouldn't need to worry.

• Writing scripts for Visual Studio project

  - by oillio

  What is the best way to write and run small scripts and tasks that are specific to a particular .Net project? Such things as configuring a database or confirming proper connections to servers. In Ruby, I would build rake tasks for this sort of thing. I am currently using unit tests for these tasks as they are easy to run within VS and they have access to all the necessary libraries and project code. However, this is not really their intended purpose and, with the dropping of Test Lists in VS 2012, it does not work nearly as well as it used to. Is there a better solution than writing a console project to handle these little code snippets I need to run periodically?

• Why are the proposed BADSIG (on apt-get update) fixes secure?

  - by EvanED

  I'm running apt-get update, and I see errors like W: GPG error: http://us.archive.ubuntu.com precise Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <[email protected]> It's not hard to find instructions on how to fix these problems, for instance by asking for the new keys with apt-key adv --recv-keys or rebuilding the cache; so I'm not asking about how to fix these. But why is this the right thing to do? Why is "oh, I need new keys? Cool, go get new keys" not just defeating the purpose of having a signed repository in the first place? Are the keys signed by a master key that apt-key checks? Should we be doing some additional validation to ensure that we're getting legitimate keys?

• Ubuntu install doesn't run on latest Nexus7 64Gb?

  - by raj

  I tried installing Ubuntu on my recently purchased (for this purpose!) Nexus 7 64Gb, with the Cellular option. When I rebooted with Ubuntu, it didn't come up. I know, I need to post the errors I received. I was in a hurry to get back to something usable for the holiday (on the road, Thanksgiving, etc.), so I just reinstalled Android for now. When I have time, I'll post more of the errors. All I remember right now is that it dropped into busybox and I didn't have a keyboard or any way to attach one. (I used the 32Gb Ubuntu, by the way.) Have others seen this? Happy Thanksgiving! More later, I promise.

• Is it normal to feel bad when someone insults a programming language? [closed]

  - by iammilind

  Few examples before the question: "A language is just a tool; Better to worry only about the concept." "C++ is just an object oriented language." "Java is more about the libraries and less about programming." "C# is just a Microsoft's version of Java with some extra things from C++." "Python is a scripting language used mainly for testing purpose." ... All these statements are made knowingly or unknowingly from my colleagues/friends and I often get to hear them. I feel bad when someone brings down any programming language. I don't know how to respond. Is there any one liner to enlighten those people?

• Using git (or any version control) regarding migration from one language to another [on hold]

  - by Max Benin

  I'm polishing an old project that i released some years ago, and the main purpose on that, is to arrange some folder structures and port the entire code from actionscript to haxe. All the game features, assets and design will remain the same. I have some doubts regarding versioning the project in this circumstance. Assuming that the only thing that will be drastically changed is the code migration, is it correct maintaining the new project changes on the same repository ? I was thinking in tagging it something like V1.1 or Branch the entire project. But i'm afraid that i'm gonna deviate from the versioning patterns. How can i use this version control issue in the best practice way ? Thanks.

• Algorithm to Sort member into groups

  - by kasmanit

  I'll have to develop an application which the final purpose is to sort all the member into groups. Each group will have the same size. And I had to put the members into the groups several times during the execution of the program. To put the member into the groups, a lot of critria are to be look at, because we do not want that two people are put again together two time in the same execution of the program, of course if it's the only way to find a correct solution, it' fine, and there is a lot of other criteria, like some people can be willing to be always with another member. So to resume, we have n members to put in groups of size 8. After the first "round" we have to do again the algorithm to sort them differently. And a lot of critria may go in the calculation of the priority of each member Do you have any idea?

• What are steps in making an operating system in C ? [duplicate]

  - by ps06756

  This question already has an answer here: Compiler/OS Design - Where to start [closed] 3 answers I am trying to make an my own OS. This is for educational purpose only, so that I get to understand the internals as well as get a good idea of low level programming. I have some prior application development experience in C#/python/C++/C. I am a noob in assembly language(very less experience and knowledge). I understand that in writing an operating system,we can't go without assembly language. Currently, I have just printed a string in assembly language in the boot sector using qemu and BIOS interrupts. What I want is that, can someone specifically point out the steps that I need to follow to make my operating systems run C programs. So that, I can start writing my OS in C. Any other piece of advice to help a newbie, regarding the same is also welcome. Although, I have looked into many os development related tutorials/websites, I can't seem to find this information anywhere.

• Looking for feedback on design pattern for simple 2D environment

  - by Le Mot Juiced

  I'm working in iOS. I am trying to make a very simple 2D environment where there are some basic shapes you can drag around with your finger. These shapes should interact in various ways when dropped on each other, or when single-tapped versus double-tapped, etc. I don't know the name for the design pattern I'm thinking of. Basically, you have a bunch of arrays named after attributes, such as "double-tappable" or "draggable" or "stackable". You assign these attributes to the shapes by putting the shapes in the arrays. So, if there's a double-tap event, the code gets the location of it, then iterates through the "double-tappable" array to see if any of its members are in that location. And so on: every interactive event causes a scan through the appropriate array or arrays. It seems like that should work, but I'm wondering if there's a better pattern for the purpose.
