  • Good practices when optimizing HTML5/Javascript Game Developement [closed]

    - by hustlerinc
    I'm just starting out as a game developer and have created a few crappy but playable clones of classic games like pong, and bomberman. Being self taught (bless the internet) I do this by just stuffing in code to make the games work. Now I feel the time has come to create something complete, for this I need to know how a game is structured. I've searched on the web but there isn't that much to be found. The only "high-level" language I know is javascript so reading a tutorial or article based on C++ doesn't help me that much. I'm looking for good resource's pedagogically covering the theory and possibly examples (in Javascript or pseudo code that is understandable for a beginner) of how the game pieces fit together. From the start screen to asset loading and running the game loop. I'm not looking for anything complicated like reading through a 4000 line source code. All I want to learn is where, how and when the main parts of every game should be called. If you know any good resources to share, or maybe even have an answer for me I would deeply appreciate it.

  • BUILD 2013 Sessions&ndash;Building Great Windows Phone UI in XAML

    Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/06/27/build-2013-sessionsndashbuilding-great-windows-phone-ui-in-xaml.aspx Even the simplest of smart phone apps can be a challenge to give a compelling UI regardless of the platform.  Windows Phone and XAML are no exception.  That is what got my interest in this session by Shawn Oster.  He took a checklist type approach to the subject is good considering that is about the only way that many us get things done. Shawn started out giving us a set of bad design/good design examples.  They very effectively showed how good design gives a sense of professionalism to your app that could determine if your wonderful idea actually makes money is DOA. I won’t go over all his points since you will be able to get the session online, but a few of his checklist points included design from the beginning instead of as an afterthought, not being afraid to leave white space and making sure your application elegantly supports both landscape and portrait modes.  The many gems make this a must watch for any developers who struggle with visual design. del.icio.us Tags: BUILD 2013,Windows Phone,XAML,Design

  • How to Create a Grid for a 2D Game?

    - by SoulBeaver
    So I'm currently writing the engine for my videogame. I've almost integrated Tiled (I think) so I should have a map-creator here soon. My question is, how do I actually make the grid? I'm really confused here. If I create a large map with, say, 20x20 grids the size of 32x32 (screen size 640x640), then what do I do with it? Let's say I have the code for creating a window, and then place a player sprite that I can move with input, that's fine. If I use one map that's as big as the screen, then every pixel on the map is also a pixel on the game screen. The mapping is exact. Now what happens if I have a 2000x2000 map, for example? My character would have to keep moving and move the map around (or rather the camera focused on the player moves). Then I can no longer say that the screen maps exactly to the pixel position of the map. I tried making a Grid class that maps out the screen area to 32x32 tiles, but I'm not sure if that makes any sense. Once the map moves each tile would have to update its information, or something. I'm just really confused here. How do I actually make the tiles and a grid and map them to the data I get from tiled, or that I make myself? Are there any good examples of source code that I could look at?

  • Pipe an infinite stream to internal loop?

    - by Sh3ljohn
    I've seen a lot of things about redirecting stdout to a TCP socket, but no real example of how to do it in practice, specifically when the output stream generated by the first "command" never ends. To talk about something concrete, let's take programs like servers that typically output their log endlessly to stdout (well, as long as they run). If you redirect the output to a log file on the disk, then this file is always open (therefore not readable by others?) and grows infinitely, which eventually is going to cause problems. This might be a nood question, but I don't know what it does or how to do it so. How to redirect the output of a command to the internal loop? I want to make sure that data is sent EVERY time something is written to stdout, and that the pipe won't wait for the command to end (never happens ideally!). Is that right? If 2 is true, is there a buffer system to send chunks of data once it reaches a certain size only? Could you give me concrete command line examples to do the above? Thanks in advance

  • Improved Customer Experience, but at what Cost? See the DELL Computer experience with RTD

    - by Richard Lefebvre
    We can all probably agree that improving your customers' experience is a good thing. But a key question many people are asking is will it help your organization and, in particular, what are the financial benefits? That's a good question, especially when companies ARE experiencing phenomenal return on investment (ROI). Of course, there are many factors that impact ROI or other measures of success, but we'd like to share some success stories as examples of customer experience in action and delivering positive results. If you would like to learn more about the economics of customer experience, see Brian Curran's presentation at the Oracle Customer Experience Summit last month. In this series of blog posts, we'll share actual customer stories. Today's example is Dell, which uses Oracle Real-Time Decisions (RTD) and Siebel CRM as part of their customer experience portfolio to better understand their customers' needs and wants and provide consistent interactions. Regular readers of this blog are probably familiar with Siebel, but RTD may be new to many of you. RTD is a complete decision management solution that delivers real-time decisions and recommendations and automatically renders decisions within a business process to create tailored messaging for every customer interaction. What does that mean? In the video below, Dell describes how customer experience is important not just for one interaction channel, but across all "vehicles." RTD is helping Dell understand customer behavior and communicate with the customer in a more relevant manner, across all communication  or interaction channels including sales and service call centers, email marketing and online. Dell continues to expand use of RTD because the benefits are showing up in sales, service and marketing results including 19% increase in close rates, faster issue resolution and 40% improvement in revenue per click in email marketing.

  • I still can't figure out how to program!

    - by Mark K.
    Please help! I've read lots of programming books for various languages, Java, Python, C, etc. I understand and know all of the basics of the languages and I understand algorithms and data structures. (Equivilant of say 2 years of CompSci classes) BUT, I still can't figure how to write a program that does anything useful. All of the programming books show you how to write the language, but NOT how to use it! The programming examples are all very basic like build a card catalog for a library or a simple game or use algorithms etc... They dont't show you how to develop complex programs that actually do anything useful! I've looked a open-source programs on sourceforge, but they don't make much sense to me. There are hundreds of files in each program & thousands of lines of code. But how do I learn how to do this? There's nothing in any book I can buy on Amazon that will give me the tools to write any of these programs. How do you go from reading Intro to Java or Programming Python, or C Programming Language, etc.. to actually being able to say, I have an idea for X Program.. this is how I go about developing it? It seems like there is so much more involved in writing a program than you can learn in a book or from a class. I feel like there is someth Can anyone put me on the right track?

  • Google Currency Convertor JSON API

    - by Gopinath
    There are many live currency conversion services available on the web and the popular one’s among them are – Google, Yahoo, MSN & XE. Among all these four Google is the developer’s darling and it provides a simple JSON API that can be integrated in your applications.  http://www.google.com/ig/calculator?hl=en&q=1USD=?INR Using the API is very simple and it takes two parameters as input. The first parameter “hl” is the language code in which you want output. The second parameter “q” is the conversion query in the format <number><from currency code>=?<to currency code>. In the URL give above the query requests for conversion of 1 USD in INR. JSON output for the above query would be  similar to {lhs: "1 U.S. dollar",rhs: "54.4602984 Indian rupees",error: "",icc: true} Examples: 100 USD in INR  http://www.google.com/ig/calculator?hl=en&q=100USD=?INR Example 2: 1 GBP in INR http://www.google.com/ig/calculator?hl=en&q=1GBP=?INR Example 3: 1 USD in INR, output the data in French language http://www.google.com/ig/calculator?hl=fr&q=1USD=?INR   This is an undocumented service and expect changes at any time. But as long as it works, you got a programmatic way to convert currencies.

  • Information about rendering, batches, the graphical card, performance etc. + XNA?

    - by Aidiakapi
    I know the title is a bit vague but it's hard to describe what I'm really looking for, but here goes. When it comes to CPU rendering, performance is mostly easy to estimate and straightforward, but when it comes to the GPU due to my lack of technical background information, I'm clueless. I'm using XNA so it'd be nice if theory could be related to that. So what I actually wanna know is, what happens when and where (CPU/GPU) when you do specific draw actions? What is a batch? What influence do effects, projections etc have? Is data persisted on the graphics card or is it transferred over every step? When there's talk about bandwidth, are you talking about a graphics card internal bandwidth, or the pipeline from CPU to GPU? Note: I'm not actually looking for information on how the drawing process happens, that's the GPU's business, I'm interested on all the overhead that precedes that. I'd like to understand what's going on when I do action X, to adapt my architectures and practices to that. Any articles (possibly with code examples), information, links, tutorials that give more insight in how to write better games are very much appreciated. Thanks :)

  • Summary of usage policies for website integration of various social media networks?

    - by Dallas
    To cut to the chase... I look at Twitter's usage policy and see limitations on what can and can't be done with their logo. I also see examples of websites that use icons that have been integrated with the look and feel of their own site. Given Twitter's policy, for example, it would appear that legal conversations/agreements would need to take place to do this, especially on a commercial site. I believe it is perfectly acceptable to have a plain text button that simply has the word "Tweet" on it, that has the same functionality. My question is if anyone can provide online (or other) references that attempt to summarize what can and can't be done when integrating various social networks into your own work? The answer I will mark as the correct one will be the one which provides the best resource(s) giving the best summaries of what can and can't be done with specific logos/icons, with a secondary factor being that a variety of social networking sites are addressed in your answer. Before people point to specific questions, I am looking for a well-rounded approach that considers a breadth of networks and considerations. Background: I would like to incorporate social media icons and functionality, but would like to consider what type of modifications can be done without needing to involve lawyers. For example, can I bring in a standard Facebook logo, but incorporate my site color into the logo? Would the answer differ if I maintained their color, but add in a few pixels of another color to transition? I am not saying I want to do this, but rather using it as an example.

  • Learning how to design knowledge and data flow [closed]

    - by max
    In designing software, I spend a lot of time deciding how the knowledge (algorithms / business logic) and data should be allocated between different entities; that is, which object should know what. I am asking for advice about books, articles, presentations, classes, or other resources that would help me learn how to do it better. I code primarily in Python, but my question is not really language-specific; even if some of the insights I learn don't work in Python, that's fine. I'll give a couple examples to clarify what I mean. Example 1 I want to perform some computation. As a user, I will need to provide parameters to do the computation. I can have all those parameters sent to the "main" object, which then uses them to create other objects as needed. Or I can create one "main" object, as well as several additional objects; the additional objects would then be sent to the "main" object as parameters. What factors should I consider to make this choice? Example 2 Let's say I have a few objects of type A that can perform a certain computation. The main computation often involves using an object of type B that performs some interim computation. I can either "teach" A instances what exact parameters to pass to B instances (i.e., make B "dumb"); or I can "teach" B instances to figure out what needs to be done when looking at an A instance (i.e., make B "smart"). What should I think about when I'm making this choice?

  • How to deal with elimination of duplicate logic vs. cost of complexity increase?

    - by Gabriel
    I just wrote some code that is very representative of a recurring theme (in my coding world lately): repeated logic leads to an instinct to eliminate duplication which results in something that is more complex the tradeoff seems wrong to me (the examples of the negative side aren't worth posting - but this is probably the 20th console utility I've written in the past 12 months). I'm curious if I'm missing some techniques or if this is really just on of those "experience tells you when to do what" type of issues. Here's the code... I'm tempted to leave it as is, even though there will be about 20 of those if-blocks when I'm done. static void Main(string[] sargs) { try { var urls = new DirectTrackRestUrls(); var restCall = new DirectTrackRestCall(); var logger = new ConsoleLogger(); Args args = (Args)Enum.Parse(typeof(Args), string.Join(",", sargs)); if (args.HasFlag(Args.Campaigns)) { var getter = new ResourceGetter(logger, urls.ListAdvertisers, restCall); restCall.UriVariables.Add("access_id", 1); getter.GotResource += new ResourceGetter.GotResourceEventHandler(getter_GotResource); getter.GetResources(); SaveResources(); } if (args.HasFlag(Args.Advertisers)) { var getter = new ResourceGetter(logger, urls.ListAdvertisers, restCall); restCall.UriVariables.Add("access_id", 1); getter.GotResource += new ResourceGetter.GotResourceEventHandler(getter_GotResource); getter.GetResources(); SaveResources(); } if (args.HasFlag(Args.CampaignGroups)) { var getter = new ResourceGetter(logger, urls.ListCampaignGroups, restCall); getter.GotResource += new ResourceGetter.GotResourceEventHandler(getter_GotResource); getter.GetResources(); SaveResources(); } } catch (Exception e) { Console.WriteLine(e.InnerException); Console.WriteLine(e.StackTrace); }

  • How much information can you mine out of a name?

    - by Finglas Fjorn
    While not directly related to programming, I figured that the programmers on here would be just as curious as I was about this question. Feel free to close the question if it does not meet with the guidelines. A name: first, possibly a middle, and surname. I'm curious about how much information you can mine out of a name, using publicly available datasets. I know that you can get the following with anywhere between a low-high probability (depending on the input) using US census data: 1) Gender. 2) Race. Facebook for instance, used exactly that to find out, with a decent level of accuracy, the racial distribution of users of their site (https://www.facebook.com/note.php?note_id=205925658858). What else can be mined? I'm not looking for anything specific, this is a very open-ended question to assuage my curiousity. My examples are US specific, so we'll assume that the name is the name of someone located in the US; but, if someone knows of publicly available datasets for other countries, I'm more than open to them too. I hope this is an interesting question!

  • Is it reasonable to require passwords when users sign into my application through social media accounts?

    - by BrMcMullin
    I've built an application that requires users to authenticate with one or more social media accounts from either Facebook, Twitter, or LinkedIn. Edit Once the user has signed in, an 'identity' for them is maintained in the system, to which all content they create is associated. A user can associate one account from each of the supported providers with this identity. I'm concerned about how to protect potential users from connecting the wrong account to their identity in our application. /Edit There are two main scenarios that could happen: User has multiple accounts on one of the three providers, and is not logged into the one s/he desires. User comes to a public or shared computer, in which the previous user left themselves logged into one of the three providers. While I haven't encountered many examples of this myself, I'm considering requiring users to password authenticate with Facebook, Twitter, and LinkedIn whenever they are signing into our application. Is that a reasonable approach, or are there reasons why many other sites and applications don't challenge users to provide a user name and password when authorizing applications to access their social media accounts? Thanks in advance! Edit A clarification, I'm not intending to store anyone's user name and password. Rather, when a user clicks the button to sign in, with Facebook as an example, I'm considering showing an "Is this you?" type window. The idea is that a user would respond to the challenge by either signing into Facebook on the account fetched from the oauth hash, or would sign into the correct account and the oauth callback would run with the new oauth hash data.

  • Fun programming or something else?

    - by gion_13
    I've recently heard about android's isUserAGoat method and I didn't know what to think. At first I laughed my brains out, than I was embarrassed for my lack of professionalism and tried to look into it and see if it makes any normal sense. As it turns out it is a joke (as stated here) and it appears that other languages/apis have these sort of easter eggs implemented in their core. While I personally like them and feel they can be a fresh breath sometimes, I think that they also can be both frustrating and confusing (and you begin to ask yourself : "can users be goats?" or "I get it! "goat" is slang for.... wait.."). My question is are there any other examples of these kind of programming jokes and what are their intends? Should they be considered harmless or not (how do programmers feel about it) ? Do they reach their goal (if any other than to laugh) ? Where do you draw a line between a good joke and a disaster? (what if the method was called isUserStupid?)

  • How to implement Restricted access to application features

    - by DroidUser
    I'm currently developing a web application, that provides some 'service' to the user. The user will have to select a 'plan' according to which she/he will be allowed to perform application specific actions but up to a limit defined by the plan. A Plan will also limit access to certain features, which will not be available at all for some plans. As an example : say there are 3 plans, 2 actions throughout the application users in plan-1 can perform action-1 3 times, and they can't perform action-2 at all users in plan-2 can perform action-1 10 times, action-2 5 times users in plan-3 can perform action-1 20 times, action-2 10 times So i'm looking for the best way to get this done, and my main concerns besides implementing it, are the following(in no particular order) maintainability/changeability : the number of plans, and type of features/actions will change in the final product industry standard/best practice : for future readiness!! efficiency : ofcourse, i want fast code!! I have never done anything like this before, so i have no clue about how do i go about implementing these functionalities. Any tips/guides/patterns/resources/examples? I did read a little about ACL, RBAC, are they the patterns that i need to follow? Really any sort of feedback will help.

  • How to enable a Web portal-based rich enterprise platform on different domains and hosts using JS without customization/ server configuration

    - by S.Jalali
    Our company Coscend has built a Web portal-based communications and cloud collaboration platform by using JavaScript (JS), which is embedded in HTML5 and formatted with CSS3. Other technologies used in the core code include Flash, Flex, PostgreSQL and MySQL. Our team would like to host this platform on five different Windows and Linux environments that run different types of Web servers such as IIS and Apache. Technical challenge: Each of these Windows and Linux servers have a different host name and domain name (and IP address), but we would like to keep our enterprise platform independent of host server configuration. Possible approach to solution: We think an API (interface module with a GUI) is needed to accomplish this level of modularity and flexibility while deploying at our enterprise customers. Seeking your insights: In this context, our team would appreciate your guidance on: Is there an algorithmic method to implement this Web portal-based platform in these Windows and Linux environments while separating it from server configuration, i.e., customizing the host name, domain name and IP address for each individual instance? For example, would it be suitable to create some JS variables / objects for host name and domain name and call them in the different implementations? If a reference to the host/domain names occurs on hundreds of portal modules, these variables or JS objects would replace that. If so, what is the best way to make these object modules written in JS portable and re-usable across different environments and instances for enterprise customers? Here is an example of the implemented code for the said platform. The following Web site (www.CoscendCommunications.com) was built using this enterprise collaboration platform and has the base code examples of the platform. This Web site is domain-specific. We like to make the underlying platform such that it is domain and host-independent. This will allow the underlying platform to be deployed in multiple instances of our enterprise customers.

  • Algorithm for grouping friends at the cinema [closed]

    - by Tim Skauge
    I got a brain teaser for you - it's not as simple as it sounds so please read and try to solve the issue. Before you ask if it's homework - it's not! I just wish to see if there's an elegant way of solving this. Here's the issue: X-number of friends want's to go to the cinema and wish to be seated in the best available groups. Best case is that everyone sits together and worst case is that everyone sits alone. Fewer groups are preferred over more groups. Sitting alone is least preferred. Input is the number of people going to the cinema and output should be an array of integer arrays that contains: Ordered combinations (most preferred are first) Number of people in each group Below are some examples of number of people going to the cinema and a list of preferred combinations these people can be seated: 1 person: 1 2 persons: 2, 1+1 3 persons: 3, 2+1, 1+1+1 4 persons: 4, 2+2, 3+1, 2+1+1, 1+1+1+1 5 persons: 5, 3+2, 4+1, 2+2+1, 3+1+1, 2+1+1+1, 1+1+1+1+1 6 persons: 6, 3+3, 4+2, 2+2+2, 5+1, 3+2+1, 2+2+1+1, 2+1+1+1+1, 1+1+1+1+1+1 Example with more than 7 persons explodes in combinations but I think you get the point by now. Question is: What does an algorithm look like that solves this problem? My language by choice is C# so if you could give an answer in C# it would be fantastic!

  • What are the advantages to use vector-based fonts over bitmap fonts in (2d) games?

    - by jmp97
    I know that many games are using bitmap fonts. Which are the advantages for vector-based font rendering / manipulation when compared to bitmap fonts and in which scenarios would they matter the most? Prefer a focus on 2d games when answering this question. If relevant, please include examples for games using either approach. Some factors you might consider: amount of text used in the game scaling of text overlaying glyphs and anti-aliasing general rendering quality font colors and styling user interface requirements localisation / unicode text wrapping and formatting cross-platform deployment 2d vs 3d Background: I am developing a simple falling blocks game in 2d, targeted for pc. I would like to add text labels for level, score, and menu buttons. I am using SFML which uses FreeType internally, so vector-based features are easily available for my project. In my view, font sizes in simple games often don't vary, and bitmap fonts should be easier for cross-platform concerns (font-formats and font rendering quality). But I am unsure if I am missing some important points here, especially since I want to polish the looks of the final game.

  • F# Objects &ndash; Part 3 &ndash; it&rsquo;s time to overload&hellip;

    - by MarkPearl
    Okay, some basic examples of overloading in F# Overloading Constructors Assume you have a F# object called person… type Person (firstname : string, lastname : string) = member v.Fullname = firstname + " " + lastname   This only has one constructor. To add additional constructors to the object by explicitly declaring them using the method member new. type Person (firstname : string, lastname : string) = new () = Person("Unknown", "Unknown") member v.Fullname = firstname + " " + lastname   In the code above I added another constructor to the Person object that takes no parameters and then refers to the primary constructor. Using the same technique in the code below I have created another constructor that accepts only the firstname as a parameter to create an object. type Person (firstname : string, lastname : string) = new () = Person("Unknown", "Unknown") new (firstname : string) = Person(firstname, "Unknown") member v.Fullname = firstname + " " + lastname   Overloading Operators So, you can overload operators of objects in F# as well… let’s look at example code… type Person(name : string) = member v.name = name static member (+) (person1 : Person , person2 : Person) = Person(person1.name + " " + person2.name)   In the code above we have overloaded the “+” operator. Whenever we add to Person objects together, it will now create a new object with the combined names…

  • How do I daemonify my daemon?

    - by jonobacon
    As part of the Ubuntu Accomplishments system I have a daemon that runs as well as a client that connects to it. The daemon is written in Python (using Twisted) and provides a dbus service and a means of processing requests from the clients. Right now the daemon is just a program I run before I run the client and it sets up the dbus service and provides an API that can be used by the clients. I want to transform this into something that can be installed and run as a system service for the user's session (e.g. starting on boot) and providing a means to start and stop it etc. The problem is, I am not sure what I need to do to properly daemonify it so it can run as this service. I wanted to ask if others can provide some guidance. Some things I need to ask: How can I treat it as a service that is run for the current user service (not a system service right now)? How do I ensure I can start, stop, and restart this session service? When packaging this, how do I ensure that it installs it as a service for the user's session and is started on login etc? In responding, if you can point me to specific examples or solutions I need to implement, that would be helpful. :-) Thanks! Jono

  • JavaScript and the User Experience

    5 sites I commonly vist at home: Google.com Gmail.com Linkedin.com Capella.edu Codeplex.com All of the top 5 sites I visit at home use JavaScript and is applied in various ways for various reasons. Gmail and Google make use of Ajax to retrieve information without the user having to call another page. In addition, all 5 of the websites use JavaScript to enhance a user's experience. Examples of this can be found in content rotation on Capella's main site and the displaying and hiding of specific content sections from within our course room. Codeplex uses Ajax and JavaScript to show dynamic content on its homepage and allow users to page through the data. I think there use of JavaScript is well placed and enhances the viewing experience of the user because it reduces the amount of interaction a user has to perform for them to obtain information they are looking to see. I have used JavaScript in various ways. One of the most memorable ways was to enable an HTML table to be able to have its rows paged and sorted based on the values in each table row.

  • Service Catalogs for Database as a Service

    - by B R Clouse
    At the end of last month, I had the opportunity to present a speaking session at Oracle OpenWorld: Database as a Service: Creating a Database Cloud Service Catalog.  The session was well-attended which would have surprised me several months ago when I started researching this topic.  At that time, I thought of service catalogs as something trivial which could be explained in a few simple slides.  But while looking at all the different options and approaches available, I came to learn that designing a succinct and effective catalog is not a trivial task, and mistakes can lead to confusion and unintended side effects.  And when the room filled up, my new point of view was confirmed. In case you missed the session, or were able to attend but would like more details, I've posted a white paper that covers the topics from the session, and more.  We start with an overview of the components of a service catalog: And then look at several customer case studies of service catalogs for DBaaS.  Synthesizing those examples, we summarize the main options for defining the service categories and their levels.  We end with a template for defining Bronze | Silver | Gold service tiers for Oracle Database Services. The paper is now available here - watch for updates as we work to expand some sections and incorporate readers' feedback (hint - that includes your feedback).

  • Documents stored on separate internal drive, Ubuntu doesn't notice on startup

    - by PlanoAlto
    My machine has Windows 7 Ultimate x64 and Ubuntu 12.04 LTS running side-by-side on a single hard drive with GRUB bootloader, each with 500 GB storage. I keep my personal documents on a separate 1TB hard drive so they remain isolated from any changes I make to the OS drive, but when Ubuntu starts it does not seem to notice my documents drive. While I've installed and worked with Ubuntu 12.04 Server x32 before, using it as a desktop OS is new to me. I use my documents drive for all of my personal data, including wallpapers and music, so it is imperative that Ubuntu recognize it on startup. Concerning the two specific examples: Ubuntu loads with the default blue-colored desktop instead of my desired picture of the spectacular Carina galaxy. When I right-click the desktop and select "Change Desktop Background", it wakes up from its amnesia and loads the proper background. As for my music, Rhythmbox defaults to an empty library upon reboot, forcing me to reload the settings manually each time. This gets quite tedious because I certainly can't work to my full potential without my music. The second thing I would like to address is making Ubuntu point the documents directories in ~ to their appropriate counterparts on the 1TB documents drive. I realize that this question is not new, but when I create the symbolical links, they established themselves inside the directories and did not convert the directories themselves into symbolical links. I also prefer not to move the files themselves from their current location on the 1TB drive. I believe this would also help the Rhythmbox library problem as well considering it's a default directory for the music player. Excerpt from fstab: proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sdb6 during installation UUID=057ac83e-76ad-460d-86e5-b6d46e9b1d80 / ext4 errors=remount-ro 0 1 # swap was on /dev/sdb7 during installation #UUID=1183df90-23fc-44e4-aa17-4e7c9865d5cb none swap sw 0 0 /dev/mapper/cryptswap1 none swap sw 0 0 That's enough content for one question. I really like the Ubuntu experience so far since it doesn't treat me like an idiot out of the box (can't say the same for Windows) so I can't wait to hear from the community! Thanks for your help in advance.
