• What is the concept behind writing a cancel operation in c++?

  - by ToMan

  I'm attempting to write a cancel operation for a software download application. This application will first transfer the software to the device and then install the software on it. (These are givens I'm not allowed to change). What should the cancel operation do? When a user presses 'cancel', the application should stop transferring/installing the software immediately. Question: Since I've never written a "cancel" function, I'm wondering what are the types of things to consider when writing the code, and what are the common bugs I should expect and how to deal with them? Couldn't find anything in google so if you have some links that would be good reads I'd really appreciate it since I'm not looking for answers I'm just looking for guidelines/macro/concept help

• Android Dynamic 2D Map

  - by Deltharis

  My problem is, I want to create a 2D tiled map. Yes, I know it's been asked a lot. I've seen answers that propose the use of tiled however it only allows (or so it seems to me) to generate static maps that do not change once generated. And I need a large empty uniform space of empty tiles, upon which players may place various buildings (some spanning more than one tile and logically being the same one). How to approach this in Android? Do I make some kind of TableLayout, use arbitrarly large amount of rows and imageviews (with my emptyTile), than somehow work event-based changing of image ids from there? I'd think that only a portion of that map should be visible at a time, but I don't see how scrolling around could be the part of that structure.

• Installer doesn't recognise windows 7 install

  - by SirWaffleRaptor

  I will start off saying I searched a bit for this problem with little success. You see, I am an utmost noob when it comes to Ubuntu and Linux based OS (hence why I want to install it and discover it) and the thread I found were too specific for me to do anything with. Therefore, if you find a thread that is noob-friendly and answers my question, please link it below or please try to answer as simply as possible :) The problem: I want to install Ubuntu 12.04 LTS 64 bit alongside Windows 7 on my main hard drive (to get the choice which one to start when booting). Pop the CD in, reboot and get to the installer screen. I know I'm supposed to have 3 options, but I'm only given the option to erase my hard drive or "do something else". Therefore, my question is: how do I make Ubuntu recognise Windows 7, so it may install alongside it?

• Is it necessary to understand what's happening at the hardware level to be a good programmer?

  - by bev

  I'm a self-taught programmer, just in case this question is answered in CS 101. I've learned and used lots of languages, mostly for my own personal use, but occasionally for professional stuff. It seems that I'm always running into the same wall when I run into trouble programming. For example, I just asked a question on another forum about how to handle a pointer-to-array that was returned by a function. Initially I'm thinking that I simply don't know the proper technique that the designers of C++ set up to handle the situation. But from the answers and discussions that follow I see that I don't really get what happens when something is 'returned'. How deep a level of understanding of the programming process must a good programmer achieve?

• Wrong download of Ubuntu 13.10 desktop: AMD instead of wanted Intel [duplicate]

  - by L. Williams

  This question already has an answer here: Difference between the i386 download and the amd64? 5 answers My PCs are Intel CPUs e.g. Core2 Quad, 64 bit, no AMD in network, but from ubuntu.com/download site, selecting 13.10 Desktop for 64 bit, it repeatedly only offers *AMD.ISO version, which of course fails to install on my Intel (or Atom) based PCs. Wuzzup, and what URL has a download for the Intel CPU systems? Rem: this is for Saucy 13.10 Desktop 64 OS ISO. TIA.

• Why does apt-get keep waiting for headers on Oracle repository?

  - by hughdbrown

  I have this at the end of my /etc/apt/sources.list to retrieve Oracle code: deb http://oss.oracle.com/debian unstable main non-free When I run sudo apt-get update, the app gets stuck displaying this message: 100% [Waiting for headers] If I remove this, apt-get update runs without error. Is there a new, recommended URL for Oracle products and, generally, how do you fix this problem? I am pretty sure this did not happen on 11.10 and has only started with the move to 12.04. I have seen these answers and they do not help: apt-get update stuck on "Waiting for Headers" http://ubuntuforums.org/showthread.php?t=1689579 http://muffinresearch.co.uk/archives/2010/03/30/linux-fix-for-apt-get-update-waiting-for-headers/ http://www.kubuntuforums.net/showthread.php?57567-Ubuntu-problems-on-update

• Dual Screens not working nVidia

  - by user91396

  So I'm very much an Ubuntu noob, in fact I just install Ubuntu to my P.C. and I started it up with both my screens plugged into my nVidia's dvi and vga ports and logged in, change the skin to classic gnome, because that's how it was when I last used Ubuntu (8.1), and both screens were working separately. The trouble is that I got a notification saying there was nVidia drivers to be installed, so I install them and restart my P.C., as it told me to, and when I get back on only one of my screens is working and when I go into Displays (All Settings, Displays) it doesn't register my other screen at all, and it calls my working screen "Laptop". I've tried looking through several pages of Google but I see no answer. I did try to find the nvidia-settings to see if that had the answers but sadly I couldn't locate it. Thanks in advance for any help, but please remember, I am very new to Ubuntu.

• Finding .desktop files based on their titles?

  - by stwissel

  That's part 2 of a question asked earlier (to be able to give credit to the answers individually). When I type into the Dash applications show up with their title (also when hovering over the launcher), how can I find the associated desktop file. When I look into the usual suspect locations (/usr/share/applications and ~/.local/share/applications) with Nautilus I see the titles, but not the file names (not even in properties which sucks). When I look from the command line I see the file names but not the titles (a switch would be nice). How can I get a listing (a custom column?) that shows them next to each other?

• Will I get penalised by google for overflow hidden? [duplicate]

  - by Rascal Capac

  This question already has an answer here: How bad is it to use display: none in CSS? 5 answers I have 2 divs next to each other, div A and div B. Div A displays a whole wordpress post and div B displays about 15 excerpts of posts with the same tag. To get this looking nice I set the hight of div B to be the same as the hight of div A with javaScript. This means alot of post excerpts will be hidden due to overflow hidden on div B. Will Google penalise me for this, and if so, how can I make this work and still please Google? Ps. I would gladly prevent the excerpts from being indexed but the main post must be indexed Ds.

• Enabling and Disabling components in Unity

  - by Blue

  I'm trying to create an enable/ disable game objects in Unity. I used GameObject.SetActiveRecursively but it only works one-way. I used a collider in which when an object enters the collider. The game objects become enabled. When they leave or get to a certain point, they disable. How would I make this a two way system, making it able to be enabled while inside the collider and disabled when outside the collider? -- The collider is in the game object who is being disabled and enabled. According to this information from Unity Answers, the object becomes disabled. So how would I make the object enabled?

• Ubuntu samba file and print server

  - by Gerd

  I am using an old Dell desktop PC as a samba file and print server for a Windows 7 network. The version of Unbuntu I am running is 12.04 which seems to big for the RAM and disk space I have available. Unbuntu 12.04 runs very very slow, the printing over the home network works at a quite acceptable speed. I have two problems: SLOW Ubuntu and I cannot update samba. The update manager tells me "update failed". So my two questions: Is there anything I can remove from the standard 12.04 installation to make Ubuntu run faster and should I uninstall and the reinstall samba to overcome the "update failed" problem? I hesitate, as printing and file serving works somehow and I don't want to loose that. I know I should give you more information to give me answers. But what would you need to know? I am not a natural Linux user. Windows 7 is still my home. Thanks in advance, Gerd

• Adding tags for SEO in clothing website [duplicate]

  - by samyb8

  This question already has an answer here: What are the best ways to increase a site's position in Google? 18 answers I am building a site for a women's accessories brand. The site has a Homepage, a Store page (where all accessories are displayed), a page for each of the accessories description, an about page and a contact page. There is also a whole set up for shopping cart and checkout (irrelevant to this question). My issue is the SEO. Where can I put the keywords? The home page has only the menu and some photos. The store page displays the items and its titles. Then the specific item's page has a description of the item (pulled from the database), category and price. However, I feel like this is not enough for SEO for google ranking. Where could I add tags in this type of site?

• What is an achievable way of setting content budgets (e.g. polygon count) for level content in a 3D title?

  - by MrCranky

  In answering this question for swquinn, the answer raised a more pertinent question that I'd like to hear answers to. I'll post our own strategy (promise I won't accept it as the answer), but I'd like to hear others. Specifically: how do you go about setting a sensible budget for your content team. Usually one of the very first questions asked in a development is: what's our polygon budget? Of course, these days it's rare that vertex/poly count alone is the limiting factor, instead shader complexity, fill-rate, lighting complexity, all come into play. What the content team want are some hard numbers / limits to work to such that they have a reasonable expectation that their content, once it actually gets into the engine, will not be too heavy. Given that 'it depends' isn't a particularly useful answer, I'd like to hear a strategy that allows me to give them workable limits without being a) misleading, or b) wrong.

• After a domain change, what can I do to recover lost traffic, rankings, impressions etc? [duplicate]

  - by Felix

  This question already has an answer here: How do I rename a domain and preserve PageRank? 3 answers I moved my site to a legacy exact-match domain I purchased about a couple of months ago. I have seen significant reduction in traffic, impressions, and rankings. I did all the right steps/best practices: change of address in GWT, map old site hierarchy and match to new site for 301 redirects etc. Indexation has gone through the Google process: old site has all but dissappeared from he index and new site is indexed, albeit with some 404 errors which I am addressing. Does anyone else who has gone through eh domain change process have any thoughts/advice? Thanks!

• Will modem manager be updated in 12.04 LTS to release 0.6.0 or above by Canonical?

  - by user204045

  It is still stuck at release 0.5.2 since early last year, while release 0.6.0 does not seem to be progressed to a stable release for 12.04 LTS. Any plans for the update to occur before the end of the year? In a related but separate question, I note that the latest Modem Manager GUI (0.0.16) has now been released for Saucy Salamander in its Software Center, but still with the older 0.0.13 version for Precise's Software Center - why does it not follow suit? Perhaps Mathieu Trudel-Lapierre or Graham Inggs can offer some help with answers if no one else can? Thanks in advance!

• Could a singleton type replace static methods and classes?

  - by MKO

  In C# Static methods has long served a purpose allowing us to call them without instantiating classes. Only in later year have we became more aware of the problems of using static methods and classes. They can’t use interfaces They can’t use inheritance They are hard to test because you can’t make mocks and stubs Is there a better way ? Obviously we need to be able to access library methods without instantiated classes all the time otherwise our code would become pretty cluttered One possibly solution is to use a new keyword for an old concept: the singleton. Singleton’s are global instances of a class, since they are instances we can use them as we would normal classes. In order to make their use nice and practical we'd need some syntactic sugar however Say that the Math class would be of type singleton instead of an actual class. The actual class containing all the default methods for the Math singleton is DefaultMath, which implements the interface IMath. The singleton would be declared as singleton Math : IMath { public Math { this = new DefaultMath(); } } If we wanted to substitute our own class for all math operations we could make a new class MyMath that inherits DefaultMath, or we could just inherit from the interface IMath and create a whole new Class. To make our class the active Math class, you'd do a simple assignment Math = new MyMath(); and voilá! the next time we call Math.Floor it will call your method. Note that for a normal singleton we'd have to write something like Math.Instance.Floor but the compiler eliminates the need for the Instance property Another idea would be to be able to define a singletons as Lazy so they get instantiated only when they're first called, like lazy singleton Math : IMath What do you think, would it have been a better solution that static methods and classes? Is there any problems with this approach?

• How to enable home directory encryption for a particular user?

  - by Ivan

  I prefer to have a dedicated "administrator" user for technical purposes and that was one I've set up during installation. I've also refused to encrypt the home folder of the user. Now, as I've added a user account for my actual work usage I want my (but not the "administrator") home folder to be encrypted. How to turn this on? If it is not possible then how to enable encryption for all users home directories on a system already installed? I've found questions and answers about how to disable it but am not sure how to enable it.
