  • Combining pathfinding with global AI objectives

    - by V_Programmer
    I'm making a turn-based strategy game using Java and LibGDX. Now I want to code the AI. I haven't written the AI code yet. I've simply designed it. The AI will have two components, one focused in tactics and resource management (create troops, determine who have strategical advantage, detect important objectives, etc) and a individual component, focused in assign the work to each unit, examine its possibilites and move the unit. Now I'm facing an important problem. The map where the action take place is a grid-based map. Each terrain has different movement cost. I read about pathfinding and I think A* is a very good option to determine a good route between two points. However, imagine I have an unit with movement = 5 (i.e, it can move 5 tiles of movement cost = 1). My tactical AI has found an objective at a distance d = 20 tiles (Manhattan distance) from my unit. My problem is the following: the unit won't be able to reach the objective in one turn. So the AI will have to store a list of position and execute them in various turns. I don't know how to solve this. PS. In my unit code, I have a list called "selectionMarks" which stores all the possible places where the unit can go in this turn. This places are calculed recursively using a "getSelectionMarks" function. Any help is appreciated :D

  • Is individual code ownership important?

    - by Jim Puls
    I'm in the midst of an argument with some coworkers over whether team ownership of the entire codebase is better than individual ownership of components of it. I'm a huge proponent of assigning every member of the team a roughly equal share of the codebase. It lets people take pride in their creation, gives the bug screeners an obvious first place to assign incoming tickets, and helps to alleviate "broken window syndrome". It also concentrates knowledge of specific functionality with one (or two) team members making bug fixes much easier. Most of all, it puts the final say on major decisions with one person who has a lot of input instead of with a committee. I'm not advocating for requiring permission if somebody else wants to change your code; maybe have the code review always be to the owner, sure. Nor am I suggesting building knowledge silos: there should be nothing exclusive about this ownership. But when suggesting this to my coworkers, I got a ton of pushback, certainly much more than I expected. So I ask the community: what are your opinions on working with a team on a large codebase? Is there something I'm missing about vigilantly maintaining collective ownership?

  • Ask the Readers: What Do You Have Set as Your Homepage?

    - by Mysticgeek
    When if comes to setting a homepage in your browser, it’s really based on personal preference. Today we want to know what you have set as your homepage in your favorite browser. Browser Homepage There are a lot of search sites that allow you to customize your homepage such as iGoogle, MSN, and Yahoo. Some people enjoy having a homepage set up as a dashboard of sorts. While others like simplicity and set it to Google or leave it blank. Not surprisingly in a small office or corporation you will see a lot of workstations set to MSN or the company SharePoint site. Unfortunately, a lot of free software tries to change you default homepage as well, like in this example when installing Windows Live Essentials. Make sure to avoid this by not rushing through software install wizards, and carefully opt out of such options. What is set as your homepage in your favorite web browser…both for work and at home?

  • "Oracle Coherence 3.5" Book - My Humble Review

    - by [email protected]
      After reviewing the book in more detail I say again that it is a great guide for sure. Lots of important concepts that sometimes can be somewhat confusing are deeply reviewed, including all types of caching schemes and backing maps, and the cache topologies with their corresponding performances and very useful "When to use it?" sections. Some functionalities that are very desirable or used a lot are reviewed with examples and best practices of implementation, including: Data affinity Querying Pagination Indexes Aggregations Event processing, listening and triggering Data persistence Security Regarding the networking and architecture topics, Coherence*Extend is exhaustively reviewed, including C++ and .NET clients, with very good tips and examples, even including source codes. Personally, I am also glad to see that the address providers (<address-provider> tag), new feature in Coherence 3.5 which is a way to programmatically provide well-known addresses in order to connect to the cluster, is mentioned on the book, because it provides new functionalities to satisfy some special configuration requirements for example: Provide a way to switch extend nodes in cases of failure Implement custom load balancing algorithms and/or dynamic discovery of TCP/IP connection acceptors Dynamically assign TCP address and port settings when binding to a server socket Another very interesting and useful section is the "Coherent Bank Sample Application", which is a great tutorial, useful to understand how Coherence interacts with third party products establishing a clear integration with them, including the use of non-Oracle products like MS Visual Studio.

  • TFS SQL Deployment Data Script

    - by Greg
    We are using TFS and SQL 2005 (looking to upgrade to SQL 2012 if that makes a difference). We store our database schema in a Visual Studio Database project (VS 2010). When code is released to live we currently use the Visual Studio Database Project to build a script for all our schema changes. The problem we have been getting is having to alter or add to that script to add/fix data for the deployment. For example if we add a new non-nullable column to an existing table we need to populate that column with data during the insert. Other times we may want to create new records in transactional tables (e.g. assign specific users to a new security access). Do Visual Studio Database Projects have a way to store these scripts that only need to be run once and somehow include them in the build? Does it know which scripts need to be run (for example if we are inserting default data we don't want to do that again a second time)? OR Is there a better way to manage these scripts?

  • two-part dice pool mechanic

    - by bythenumbers
    I'm working on a dice mechanic/resolution system based off of the Ghost/Echo (hereafter shortened to G/E) tabletop RPG. Specifically, since G/E can be a little harsh with dealing out consequences and failure, I was hoping to soften the system and add a little more player control, as well as offer the chance for players to evolve their characters into something unique, right from creation. So, here's the mechanic: Players roll 2d12 against the two statistics for their character (each is a number from 2-11, and may be rolled above or below depending on the nature of the action attempted, rolling your stat exactly always fails). Depending on the success for that roll, they add dice to the pool rolled for a modified G/E style action. The acting player gets two dice anyhow, and I am debating offering a bonus die for each success, or a single bonus die for succeeding on both of the statistic-compared rolls. One the size of the dice pool is set, the entire pool is rolled, and the players are allowed to assign rolled dice to a goal and a danger. Assigned results are judged as follows: 1-4 means the attempted goal fails, or the danger comes true. 5-8 is a partial success at the goal, or partially avoiding the danger. 9-12 means the goal is achieved, or the danger avoided. My concerns are twofold: Firstly, that the two-stage action is too complicated, with two rolls to judge separately before anything can happen. Secondly, that the statistics involved go too far in softening the game. I've run some basic simulations, and the approximate statistics follow: 2 dice (up to) 3 dice (up to) 4 dice failure ~33% ~25% ~20% partial ~33% ~35% ~35% success ~33% ~40% ~45% I'd appreciate any advice that addresses my concerns or offers to refine my simulation (right now the first roll is statistically modeled as sign(1d12-1d12), where 0 is a success).

  • How do Unity 12.04/Compiz bindings really work?

    - by Daniel
    There is a bewildering array of places to set bindings, all inconsistent with one another. E.g. in Unity's System Settings having the Ctrl-key highlight the mouse position is an on/off choice. I like the feature, but not on such a prominent key where I keep activating it accidentally. The keyboard shortcuts allow only one binding per command, where I might like a convenient one on the external keyboard and an emergency alternative for when I'm on the road. Keyboard custom shortcuts has a nice interface, but allows only key bindings — besides it doesn't seem to work for me. So I activated CCSM Commands. There I have the choice of key-, mouse- and/or edge bindings. Whereas some places in CCSM offers only one or two of these binding possibilities, randomly at the whim of the programmer. I have not found a way to differentiate a mouse-drag from a click. E.g. I want <SuperMouse1-drag anywhere on a window to move it, while if I don't drag, it should be raise-lower. On the title bar I want the same without needing the <Super key. Now I find raise-lower only in System Settings where I can't assign a mouse binding. If therefore in CCSM I fallback to only lower and put move on the same binding, the window already gets lowered on mouse down, and I can then invisibly move it. Very useful! I have <Altasciicircum get in the way of an Emacs binding, with some to me useless popup overlay. I can find it nowhere, so I can't turn it off. So how can I go without these frontends until they have matured, and instruct Compiz directly, for example in the way Emacs or Sawfish have keymaps, and separate ones for each context, with inheritance?

  • Clustering Strings on the basis of Common Substrings

    - by pk188
    I have around 10000+ strings and have to identify and group all the strings which looks similar(I base the similarity on the number of common words between any two give strings). The more number of common words, more similar the strings would be. For instance: How to make another layer from an existing layer Unable to edit data on the network drive Existing layers in the desktop Assistance with network drive In this case, the strings 1 and 3 are similar with common words Existing, Layer and 2 and 4 are similar with common words Network Drive(eliminating stop word) The steps I'm following are: Iterate through the data set Do a row by row comparison Find the common words between the strings Form a cluster where number of common words is greater than or equal to 2(eliminating stop words) If number of common words<2, put the string in a new cluster. Assign the rows either to the existing clusters or form a new one depending upon the common words Continue until all the strings are processed I am implementing the project in C#, and have got till step 3. However, I'm not sure how to proceed with the clustering. I have researched a lot about string clustering but could not find any solution that fits my problem. Your inputs would be highly appreciated.

  • proper way to creation multiple similiar buttons/panels

    - by JayAvon
    I have the below Code which i tried to do, but it only shows(the minus/plus button) on the last GirdLayout (Intelligence stat): JButton plusButton = new JButton("+"); JButton minusButton = new JButton("-"); statStrengthGridPanel = new JPanel(new GridLayout(1,3)); statStrengthGridPanel.add(minusButton); statStrengthGridPanel.add(new JLabel("10")); statStrengthGridPanel.add(plusButton); statConstitutionGridPanel = new JPanel(new GridLayout(1,3)); statConstitutionGridPanel.add(minusButton); statConstitutionGridPanel.add(new JLabel("10")); statConstitutionGridPanel.add(plusButton); statDexterityGridPanel = new JPanel(new GridLayout(1,3)); statDexterityGridPanel.add(minusButton); statDexterityGridPanel.add(new JLabel("10")); statDexterityGridPanel.add(plusButton); statIntelligenceGridPanel = new JPanel(new GridLayout(1,3)); statIntelligenceGridPanel.add(minusButton); statIntelligenceGridPanel.add(new JLabel("10")); statIntelligenceGridPanel.add(plusButton); I know I can do something like I did for the Panel names(have multiple ones), but I did not want to do that for the Panels in the first place. I am trying to use best practice and not have my code be repetitive. Any suggestions?? The goal is to have 4 stats, to assign points to, with decrement and increment buttons(I decided against sliders). Eventually I will have them have upper and lower limits, decrement the "unused" label, and all of that good stuff, but I just want to not be repetitive. Thanks for any help.

  • Hosting files with support for file tagging / keywords

    - by Zev Chonoles
    I have a large (approx. 25GB) collection of files I would like to host online for people to view or download. I have a spare computer I can use as a dedicated server for these files. I'm looking for a method of, or piece of software for, hosting my files where I can assign tags or keywords to the files, and people viewing my files online can search the collection via the tags. By way of approximate solutions I've found so far, I see that there is software such as Collectorz.com or Readerware for creating databases of one's books / music / movies, and these databases can be searched by tags or keywords, and the databases can be made available and searchable online; this would suit my purposes except that my files are not necessarily books, music, or movies, and I want the files themselves accessible online, not a database describing my files. A commercially-available solution like the ones above would be acceptable, but I'd prefer to have the whole setup under my control (i.e. I'd like to either implement it by hand, or use commercial software that doesn't rely on using the company's servers, paying them a continued fee, etc.). The current extent of my internet experience is designing a few Google Sites, so I know there's a fair chance I won't understand the answers I receive, but I'm always happy to have a summer project :)

  • Setting up group disk quotas

    - by Ray
    I am hoping to get some advice in setting up disk quotas. So, I know about: Adding usrquota and grpquota on to /etc/fstab for the file systems that need to be managed. Using edquota to assign disk quotas to users. However, I need to do the last step for multiple users and edquota seems to be a bit troublesome. One solution that I have found is that I can do: sudo edquota -u foo -p bar. This will copy the disk quota of bar to user foo. I was wondering if this is the best solution? I tried setting up group disk quotas but they don't seem to be working. Are group quotas meant to help in the assignment of the same quota to multiple users? Or are they suppose to give a total limit to a set of users? For example, if users A, B, C are in group X then assigning a quota of 20 GB gives each user 20 GB or does it give 20 GB to the entire group X to divide up? I'm interested in doing the former, but not the latter. Right now, I've assigned group disk quotas and they aren't working. So, I guess it is due to my misunderstanding of group disk quotas... My problem is I want to easily give the same quota to multiple users; any suggestions on the best way to do this out of what I've tried above or anything else I may not have thought of? Thank you!

  • suggestions for lonewolf dev setup

    - by d33j
    I'm looking for some suggestions for a better development setup. Background: I'm a crusty old software engineer (mostly java of late) and I have around 50 - 100 incomplete java projects scattered everywhere, usb keys, HDDs, and spanning across 5 or 6 computers etc, which have been put on hold for a few years (ie: family). I have no version control at home. I've been using IntelliJ for around 10 years, so that's the only constant. I'm thinking of nominating one machine as a headless server to put all my projects on, maybe a ubuntu box, that way It won't matter which device I'm on, all my projects can be accessed (and I don't have to waste time actually looking for them). I don't need to access code over the net. These are my own 'happy place' projects so I only work on them when I'm at home, however I can see the benefit of the tasking app being online, that way if I think of something while on public transport lets say, I can add it then & there, but it's not a requirement. I can wait until I get home to create tasks. Summary: So I need some sort of version control so I can rollback mistakes, and some sort of simple tasking software where I can assign tasks for myself later on when I get time. I use Subversion, Sonar, Jira and Crucible at work but I think it's a little bit of an overkill for me though. What do you suggest?

  • Laptop power button not working

    - by DyP
    I have a (seemingly rather exotic) Dell Latitude XT2 notebook running Lubuntu 12.04, fresh install. Tried to get the power button to work as expected (opening lubuntu-logout, just as I think it was meant to be out-of-the box), but no success: power button does nothing but forced power-off on long press. Here some more information, please ask if something more could help: Power button is recognized as a device: xinput lists Power Button as a slave keyboard at /dev/input/event1, and I can run a tool to listen to that device and invoke some action (successfully). But using .config/openbox/lubuntu-rc.xml to assign some action to XF86ShutDown or XF86PowerOff does nothing. Works well for any key of the keyboard. xinput --test reports a keycode (key press, key release) of 124 when pressing & releasing the power button. xmodmap -pk lists 124 mapped to XF86PowerOff which seems correct to me (btw: is this the same as XF86ShutDown?) When assigning another keysymname to the 124 keycode, e.g. 'w', still nothing happens when pressing the power button (no window seems to receive a 'w'). Works well for any key on the keyboard. The outputs of xev for a press/release of the power button irritate me: MappingNotify event, serial 41, synthetic NO, window 0x0, request MappingKeyboard, first_keycode 8, count 248 FocusOut event, serial 41, synthetic NO, window 0x2a00001, mode NotifyGrab, detail NotifyAncestor FocusIn event, serial 41, synthetic NO, window 0x2a00001, mode NotifyUngrab, detail NotifyAncestor KeymapNotify event, serial 41, synthetic NO, window 0x0, keys: 93 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 (instead of 93, I also get different values) I might have missed something very basic since I'm not very familiar with both openbox/lubuntu and the X input system. Btw.: same goes for three other special buttons on my laptop..

  • C# find a value from an object column using a string from another column

    - by Graham
    I have 2 list in foreach loops.. I currently use a 'switch' statement on the m.columnname and then assign the value of that column to another var map as per below.. If m.columnname = 'DocHeading' then v.docheading is assigned to map.value.. There will always be a match on m.columnname to a column in the var v. is there a way to get the value from the var v using the string from m.columnname? The reason is that the users will want to add and change column names and I dont want to have to change this code all the time.. Hope this makes sense List spreadMapping = new List(); foreach (var m in mappings) { foreach (var v in hvalues) { SpreadMappings map = new SpreadMappings(); switch (m.ColumnName) { case “DocHeading”: map.ColumnX = m.ColumnX; map.ColumnY = m.ColumnY; map.ColumnValue = v.DocHeading; map.ColumnName = m.ColumnName; map.ColumnId = v.Id; map.ColumnSheetName = sheetName; spreadMapping.Add(map); break;

  • Assigning a script to a keystroke to toggle touchpad

    - by sodiumnitrate
    Since my default sony vaio shortcuts don't completely work in Ubuntu 12.04, I'd like to assign a script to Fn + F1, which toggles the touchpad on and off, so that the cursor would stop moving while I'm typing. Since I use a mouse and rarely need to use the touchpad, I don't want to use "disable touchpad while writing", which doesn't really seem to work anyway. I figured that using a script with the following command (this works, but I have to open up a terminal each time): xinput set-prop 12 "Device Enabled" 0 I have two problems at this point. One is that I don't know how to write this script so that it will toggle it off if it is on, and on if it is off. I know I should use an if statement but I don't know what value I should be checking to see if it is on or off. The second one is that I am having problems creating a new shortcut. I use System Settings - Keyboard - Shortcuts. I tried to add, to custom shortcuts, a new one by clicking the '+' sign. I named it Toggle Touchpad, and added the path to the executable script with the line above, by typing /home/irem/.toggletouchpad I have made it an executable with chmod. The problem is that when I click apply, and then click back on it to define the keystroke, it re-opens the dialogue. I cannot define new keys. (It says disabled on the right column of the entry). I have also tried xbindkeys, which almost constantly crashes. I'd prefer the system settings, if I can set the shortcut. I'd appreciate if anyone can help. Thanks.

  • Android Game Development problem whith size and speed

    - by Charlton Santana
    I have been coding speed for an object. I have made it so the object will move from one end of the screen to another at a speed depending on the screen size, at the monemt I have made it so it will take one second to pass the screen. So i have worked out the speed in code but when I go to assign the speed it tells me to force close and i do not understand why. Here is the code: MainGame Code: @Override protected void onDraw(Canvas canvas) { setBlockSpeed(getWidth()); } private int blockSpeed; private void setBlockSpeed(int screenWidth){ Log.d(TAG, "screenWidth " + screenWidth); blockSpeed = screenWidth / 100; // 100 is the FPS.. i want it to take 1 second to pass the screen Math.round(blockSpeed); // to make it a whole number block.speed = blockSpeed; // if i dont put blockSpeed and put eg 8 it still tells me to force close } Block.java Code: public int speed; public void draw(Canvas canvas) { canvas.drawBitmap(bitmap, x - (bitmap.getWidth() / 2), y - (bitmap.getHeight() / 2), null); if(dontmove == 0){ this.x -= speed; } }

  • Fresh install of 64 bit 12.04 over 32 bit 11.10 alongside Windows 7

    - by Pareen
    I currently have Ubuntu 11.10 32 bit and Windows 7 dual boot in separate partitions. I am trying to do a fresh install of Ubuntu 12.04 64 bit (mistakenly installed the 32 bit 11.10 a little while ago.. I need a 64 bit version to support AOSP build) OVER my the exisiting 11.10 partition. I have referenced How to Install fresh 12.04 install to a PC with dual booting Windows 7 & Ubuntu11.10?, as well as other posts on using the Live CD to do a fresh install. However, the problem I am experiencing is when I bring up the install screen, it says the following: This computer has multiple operating systems on it. What would you like to do. (3 options) Install Ubuntu 12.04 alongside them Replace all with Ubuntu 12.04 (Warning, this will delete files across ALL operating systems) Something else (you can create or resize partitions yourself) This is different from what is in other posts, as mine states that there are "multiple O.Ses" and doesnt individually allow me to replace the Ubuntu 11.10. I don't want to replace ALL O.S.es: I need to preserve Windows 7 and am only trying to replace the old Ubuntu 11.10 partition with the new 12.04 64 bit. I did have Ubuntu installed via Wubi (I believe it was 10.04) prior to putting 11.10 in a separate partition, but I have removed it via Add/Remove programs in Windows. I was wondering how to go about doing this... Should I use the "Something else" option to bring up the partition manager, and just assign my existing 11.10 partition with root mount point + swap space. Will this do the same thing by overwriting with fresh 12.04 install?? I appreciate all your help.

  • What would be the fastest way of storing or calculating legal move sets for chess pieces?

    - by ioSamurai
    For example if a move is attempted I could just loop through a list of legal moves and compare the x,y but I have to write logic to calculate those at least every time the piece is moved. Or, I can store in an array [,] and then check if x and y are not 0 then it is a legal move and then I save the data like this [0][1][0][0] etc etc for each row where 1 is a legal move, but I still have to populate it. I wonder what the fastest way to store and read a legal move on a piece object for calculation. I could use matrix math as well I suppose but I don't know. Basically I want to persist the rules for a given piece so I can assign a piece object a little template of all it's possible moves considering it is starting from it's current location, which should be just one table of data. But is it faster to loop or write LINQ queries or store arrays and matrices? public class Move { public int x; public int y; } public class ChessPiece : Move { private List<Move> possibleMoves { get; set; } public bool LegalMove(int x, int y){ foreach(var p in possibleMoves) { if(p.x == x && p.y == y) { return true; } } } } Anyone know?

  • Developing an Interface to a Dynamic System

    - by radix07
    I work for a small company and have been designing a GUI to interface our embedded system. The problem with this embedded system is that it is not a finished product (may never be) and is constantly under development and being tweaked and updated for different customers and applications in small volumes. So to deal with this I made a program that can export all the data from a spreadsheet where most of the embedded system variables are sourced from and throw them into a small database for the GUI application to use. This database program I made also spits out a cross reference file for the embedded system which allows the GUI to look up all the variables. This system works pretty well so far, and is even integrated with version control among the GUI, database, and embedded system. The big problem is that there is constant development on several projects that use this system and it gets terribly tedious to keep the system up to date and bring in new changes. This has gotten to the point to where I have had to code the GUI to dynamically (generically) generate all interfaces since I am never guaranteed to find the same data the same way. I have not been able to come up with a good way to uniquely identify the data I import from excel since all fields are able to be changed (due to engineering stubbornness, code re-factoring and/or excel issues) and I cannot assign a fixed reference within the sheet itself. So, are there any good methods or ideas on how to handle the chaos?

  • Nullable types and ?? operator C# [en-US]

    - by ruimachado
    Nullable types vs Non-nullable types   While developing our C# projects its frequent the null comparison operation to avoid null exceptions. This simple operation is mainly coded using the "var x = null" code example inside an if clause. However not all types of variables are nullable, which means that setting a variable to null is not allowed in every cases, it depends on what kind of type are you defining. But what if there was an extension to your non-nullable type that would convert your variable types to nullable? This extension really exists. As I said before in C# you have nullable types which represent all the values of an underlying type, and an additional null value and can be declared easily using "T?", where T is the type of the variable and for example the normal int type cannot be null, so its a non-nullable type, however if you define a "int?" your variable can be null, what you do is convert a non-nullable type to a nullable type. Example: int x=null;     Not allowed     int? x=null;   Allowed     While using nullable types you can check if a variable is null the same way you do it with nullable types:     But what about setting a default value when a certain variable is null?   In this cases the c# .net framework let you set a default value when you try to assign a nullable type to a non-nullable type, using the ?? operator. If you don't use this operator you can still catch the InvalidOperationException which is throw in this cases. For example  without the ?? operator :     Using the ?? operator your code becomes cleaner and more easy to read and you get a bonus, you can set a default value for multiple variables using the ?? in a chain set.     That’s it,   Thanks, Rui Machado rpmachado.wordpress.com

  • Calculation of Milestones/Task list

    - by sugar
    My project manager assigned me a task to estimate the development time for an iPad application. Lets assume that I gave estimation of 15 working days. He thought that the number of days where too many and client needed the changes to the application urgently (as in most of cases). So, he told me: "I am going to assign two developer including you and as per my understandings and experience it won't take more than seven working days." Clarifications I was given the task of estimating development time for an individual. How could I be sure that 2 developers are going to finish it within 7 days? (I am new to team & I hardly know the others abilities) Questions Why do most of project managers / team leaders have understandings like: If one developer requires N days, Then two developers would require N/2 days, Do they think something like developer = s/w production machines? Should a team member (developer, not team lead or any higher post) estimate other developers work? I didn't deny anything in the meeting and didn't said, but what should be the appropriate answer to convince them that N/2 formula that they follow is not correct?

  • View the Time & Date in Chrome When Hiding Your Taskbar

    - by Asian Angel
    Do you prefer keeping your Taskbar hidden but still need to keep watch on what time it is? Now you can keep track of the time without the Taskbar using the Date Today extension for Google Chrome. A Look at Date Today with Different Themes This extension does one thing and does it well…it provides you with an “active icon” clock that will let you view the time and date in two fashions. The first is by hovering your mouse over the “Toolbar Clock Button”… And the second is by clicking on the “Toolbar Clock Button” to view an enlarged version. Here you can see the extension in use with five different themes to get an idea of how it might look with the theme that you are currently using. It does stand out very nicely with brighter or darker colored themes. Conclusion While this extension is obviously not for everyone it will make a nice (and useful) addition to Chrome for those who prefer keeping their Taskbar hidden.

  • How to automatically mount a folder and change ownership from root in virtualbox

    - by Fiztban
    It is my first time using virtualbox and ubuntu (14.04), I am on a host Windows 7 OS. I am trying to mount a shared folder that has files I need to access both in the virtualbox and on the windows OS. I have successfully mounted them using the vboxsf from the Guest Additions installed. To mount I used the command sudo mount -t vboxsf <dir name in vbox> <directory in linux for example I used sudo mount -t vboxsf Test /home/user/Test I found several ways of mounting the directories automatically upon startup using for example the /etc/rc.local method (here) where you modify said file appending the command to it (without sudo). Or by using the fstab method (here). I prefer the rc.local method personally. Once mounted it has permissions dr-xr-xr-x however once mounted the directory is of root ownership and chown user /home/user/Test has no effect. This means I cannot make or change files in it as a normal user. In the VirtualBox the directory to be shared is not set as read-only. Is there a way to automatically mount the shared folder and assign ownership to my non root user?
