  • How to Quickly Encrypt Removable Storage Devices with Ubuntu

    - by Chris Hoffman
    Ubuntu can quickly encrypt USB flash drives and external hard drives. You’ll be prompted for your passphrase each time you connect the drive to your computer – your private data will be secure, even if you misplace the drive. Ubuntu’s Disk Utility uses LUKS (Linux Unified Key Setup) encryption, which may not be compatible with other operating systems. However, the drive will be plug-and-play with any Linux system running the GNOME desktop. HTG Explains: What Is RSS and How Can I Benefit From Using It?

  • Sony Ericsson txt: workhorse feature phone with Java ME tech

    - by hinkmond
    Just like your basic Quarter Horse, the new Sony Ericsson txt feature phone might not be as fancy as a "thoroughbred" smartphone, but it can sure get the job done with Java ME technology. See: Sony Ericsson txt w/Java ME Here's a quote: ...comes with the usual features such as a web browser, email client and music player and FM radio, plus support for social networking applications and a YouTube client. You can download and install additional Java applications... Sometimes the simple workhorse feature phone (with Java ME) is much better to go with than the idiosyncratic thoroughbred smartphone.

  • Recover that Photo, Picture or File You Deleted Accidentally

    - by The Geek
    Have you ever accidentally deleted a photo on your camera, computer, USB drive, or anywhere else? What you might not know is that you can usually restore those pictures—even from your camera’s memory stick. Windows tries to prevent you from making a big mistake by providing the Recycle Bin, where deleted files hang around for a while—but unfortunately it doesn’t work for external USB drives, USB flash drives, memory sticks, or mapped drives. The great news is that this technique also works if you accidentally deleted the photo… from the camera itself. That’s what happened to me, and prompted writing this article. Restore that File or Photo using Recuva The first piece of software that you’ll want to try is called Recuva, and it’s extremely easy to use—just make sure when you are installing it, that you don’t accidentally install that stupid Yahoo! toolbar that nobody wants. Now that you’ve installed the software, and avoided an awful toolbar installation, launch the Recuva wizard and let’s start through the process of recovering those pictures you shouldn’t have deleted. The first step on the wizard page will let you tell Recuva to only search for a specific type of file, which can save a lot of time while searching, and make it easier to find what you are looking for. Next you’ll need to specify where the file was, which will obviously be up to wherever you deleted it from. Since I deleted mine from my camera’s SD card, that’s where I’m looking for it. The next page will ask you whether you want to do a Deep Scan. My recommendation is to not select this for the first scan, because usually the quick scan can find it. You can always go back and run a deep scan a second time. And now, you’ll see all of the pictures deleted from your drive, memory stick, SD card, or wherever you searched. Looks like what happened in Vegas didn’t stay in Vegas after all… If there are a really large number of results, and you know exactly when the file was created or modified, you can switch to the advanced view, where you can sort by the last modified time. This can help speed up the process quite a bit, so you don’t have to look through quite as many files. At this point, you can right-click on any filename, and choose to Recover it, and then save the files elsewhere on your drive. Awesome! Restore that File or Photo using DiskDigger If you don’t have any luck with Recuva, you can always try out DiskDigger, another excellent piece of software. I’ve tested both of these applications very thoroughly, and found that neither of them will always find the same files, so it’s best to have both of them in your toolkit. Note that DiskDigger doesn’t require installation, making it a really great tool to throw on your PC repair Flash drive. Start off by choosing the drive you want to recover from…   Now you can choose whether to do a deep scan, or a really deep scan. Just like with Recuva, you’ll probably want to select the first one first. I’ve also had much better luck with the regular scan, rather than the “dig deeper” one. If you do choose the “dig deeper” one, you’ll be able to select exactly which types of files you are looking for, though again, you should use the regular scan first. Once you’ve come up with the results, you can click on the items on the left-hand side, and see a preview on the right.  You can select one or more files, and choose to restore them. It’s pretty simple! Download DiskDigger from dmitrybrant.com Download Recuva from piriform.com Good luck recovering your deleted files! And keep in mind, DiskDigger is a totally free donationware software from a single, helpful guy… so if his software helps you recover a photo you never thought you’d see again, you might want to think about throwing him a dollar or two.

  • How to implement turn-based game engine?

    - by Dvole
    Let's imagine game like Heroes of Might and Magic, or Master of Orion, or your turn-based game of choice. What is the game logic behind making next turn? Are there any materials or books to read about the topic? To be specific, let's imagine game loop: void eventsHandler(); //something that responds to input void gameLogic(); //something that decides whats going to be output on the screen void render(); //this function outputs stuff on screen All those are getting called say 60 times a second. But how turn-based enters here? I might imagine that in gameLogic() there is a function like endTurn() that happens when a player clicks that button, but how do I handle it all? Need insights.

    - by marcg11
    I hope someone knows how to do the following with cocos2d: I want a sprite to move but not in a single line by using [cocosGuy runAction: [CCMoveTo actionWithDuration:1 position:location]]; What I want is the sprite to do some kind of movements that I preestablish. For example in some point i want the sprirte to move for instance up and then down but in a curve. Do I have to do this with flash like this documents says? http://www.cocos2d-iphone.org/wiki/doku.php/prog_guide:animation Does animation in this page means moving sprites or what? thanks

  • HTML Javascript Hidden Object or Photo Hunt Game

    - by PeteT
    Is anyone aware of any example photo hunt/hidden object games either in HTML and Javascript or flash if necessary? I am having trouble finding one, I may be using the wrong words to search. Photo hunt being like the wheres wally/waldo books where you look for wally in a complex image until you find him. So if it were played on screen you would press the location of wally and it would either be correct or wrong, possibly timed. I am hoping to find one where you can just load in your own photos and specify some co-ordinates that match where the hidden object is. A spot the difference example may be useful as a starting point but I haven't found an example of either that is web based yet.

  • Flixel Game Over Screen

    - by Jamie Read
    I am new to game development but familiar with programming languages. I have started using Flixel and have a working Breakout game with score and lives. I am just stuck on how I can create a new screen/game over screen if a player runs out of lives. I would like the process to be like following: Check IF lives are equal to 0 Pause the game and display a new screen (probably transparent) that says 'Game Over' When a user clicks or hits ENTER restart the level Here is the function I currently have to update the lives: private function loseLive(_ball:FlxObject, _bottomWall:FlxObject):void { // check for game over if (lives_count == 0) { } else { FlxG:lives_count -= 1; lives.text = 'Lives: ' + lives_count.toString() } } Here is my main game.as: package { import org.flixel.*; public class Game extends FlxGame { private const resolution:FlxPoint = new FlxPoint(640, 480); private const zoom:uint = 2; private const fps:uint = 60; public function Game() { super(resolution.x / zoom, resolution.y / zoom, PlayState, zoom); FlxG.flashFramerate = fps; } } }

  • 3D collision detection with meshes using only raycasting?

    - by Nick
    I'm building a game using WebGL and Three.js, and so far I have a terrain with a guy walking on it. I simply cast a ray downwards to know the terrain height. How can I do this for other 3D objects, like the inside of a house? Is this possible by casting many rays in every direction of the player? If not, I would like to know how I can achieve the simplest collision detection possible for other meshes. Do you have to cast a ray to every triangle in every mesh nearby?

  • Can I share a TV card?

    - by Boris
    My environment: 2 PCs, a desktop and a laptop, both on Oneiric they are connected together by ethernet wire nfs-common is installed and configured: the desktop is the server a TV tuner card is installed on the desktop, I can watch TV with the software Me-TV It works fine, TV on desktop, and my network too: I share folders thanks to NFS. But I would like more: How can I share my TV tuner card from the desktop and be able to watch TV on the laptop too? If possible I would like a solution that allows me to keep using the software Me-TV, on both PCs. I bet that there is a solution to create a fake TV card on the 2nd PC with xNBD. I'm trying xnbd-server --target /dev/dvb/adapter0/demux0 but I cant make it work. Trying to understand some examples of xNBD command lines, it seems to be meant only for sharing disk player. If someone as ever used xNBD, he's welcome.

  • Podcast Best Practices - Page Development & Monetization Considerations

    - by Christopher Ickes
    Our current podcast page has show notes and a link to download an mp3 of our podcast. We were advised to add an audio player to stream the file live from our website. The thought being this would improve time spent on our site and allow for greater advertising dollars. Is it better to have a page with show notes, an mp3 for download AND also stream the podcast live OR just stick to the show notes & mp3 download? Does anyone see any affect on advertising revenue, either way?

  • Online Multiplayer Game Architecture [on hold]

    - by Eric
    I am just starting to research online multiplayer game development and I have a high-level architectural question regarding how online multiple games function. I have server-side and client-side programming experience, and I understand how AJAX-esque transfer protocol operates. What I don't understand yet is how online multiple fits into all of that. For example, an online Tetris multiplayer game. Would both players have the entire Tetris game built out on their client-side and then get pushed "moves" from the other player via some AJAX-esque mechanism, in which case each client would have to be constantly listening via JavaScript for inbound "moves" and update the client appropriately? Or would each client build out the aesthetics and run a virtual server per game to which each client connects and thus pull and push commands in real-time via something like web sockets? I apologize if this question is too high-level and general, but I couldn't find anything online that offered this high-level of a perspective on the topic.

  • Objective - Gestures while finger touches screen

    - by marcg11
    I'm creating a space cocos2d game with objetive-c. I have in the bottom left 2 arrows to move the sprite left or right. I also implemented a swipe gesture to change weapon, however it only happens when I'm not touching the screen. I would like the player to change weapons while he's moving the sprite and not have to lift the finger from the arrows and stop moving the sprite to change weapons. Is there any way I can detect Gestures while having a finger pressed un a buton in thes screen?

  • How can I embed an existing podcast into my website?

    - by michaellindahl
    I manage a podcast and a website, currently they are separate but I would like to have a way to embed the podcast into the website, I still want to create/update the podcast separate from the website I just want visitors to be able to listen to the podcast on the website without having to open iTunes while still having the ability to choose what episode to play. The best solution I have found is: http://tools.wizzard.tv/ but I do not like it that much. Currently I have to log on and click refresh for it to recognize new episodes. I want to be able to update the podcast, and just like how iTunes will be updated I want the page on the website to be updated as well. The 'podcast' page will most likely not be like a blog but have a Flash or Java script application that will pull the info from the podcast.xml file to show the episodes.

  • What should be contained in a game scene graph?

    - by Bunkai.Satori
    Would you help me to clarify, please, what what exactly should be contained within a game scene graph? See the following list, please: Game Actors? (obviously yes, all the objects changing state should be the major prart of the Scene Graph) Simple static game ojbects? (I mean ojects places in the background that do not get animated, neither do they collide) Game Triggers? Game Lights? Game Cameras? Weapon Bullets? Game Explosions and Special Effects? The above considered object types. Now to the coverage of the scene graph: Should a scene graph contain the whole game level map since the level start, or should it contain only the visible portion of the map? If the second is true, it would mean that scene graph would be continuously updated, by adding/removing game objects, as the player moves. However, containing only the visible are of the map obviously would be much faster to traverse and update.

    We have planned to take up an user story say As a player I want to view the game map to know current standings of my team The sprint is for two weeks. We will be able to complete only HTML in two weeks time, this user story will take 4-6 weeks to be completed as we have a shortage of content designing resources. How can we change this user story so that HTML completion can be considered as a done for this user story and we need to take up the integration of this user story in the next sprint? Is it possible to create two different user stories, one for HTML and other for integration, testing, bug fixing etc?

  • Design patterns frequently seen in embedded systems programming

    - by softwarelover
    I don't have any question related to coding. My concerns are about embedded systems programming independent of any particular programming language. Because I am new in the realm of embedded programming, I would quite appreciate responses from those who consider themselves experienced embedded systems programmers. I basically have 2 questions. Of the design patterns listed below are there any seen frequently in embedded systems programming? Abstraction-Occurrence pattern General Hierarchy pattern Player-Role pattern Singleton pattern Observer pattern Delegation pattern Adapter pattern Facade pattern Immutable pattern Read-Only Interface pattern Proxy pattern As an experienced embedded developer, what design patterns have you, as an individual, come across? There is no need to describe the details. Only the pattern names would suffice. Please share your own experience. I believe the answers to the above questions would work as a good starting point for any novice programmers in the embedded world.

  • Diagonal line of sight with two corners

    - by Ash Blue
    Right now I'm using Bresenham's line algorithm for line of sight. The problem is I've found an edge case where players can look through walls. Occurs when the player looks between two corners of a wall with a gap on the other side at specific angles. The result I want is for the tile between two walls to be marked invalid as so. What is the fastest way to modify Bresenham's line algorithm to solve this? If there isn't a good solution, is there a better suited algorithm? Any ideas are welcome. Please note the solution should also be capable of supporting 3d. Edit: For the working source code and an interactive demo of the completed product please see http://ashblue.github.io/javascript-pathfinding/

    So at the moment am making a simple game using three.js and three.firstpersonControls.js but with the current Three.js r66, they apparently removed checkWallCollision and then in the r67 firstpersonControls removed support for that collision. SO my question is how would i go about checking collision in 3D using three.js and then resolution to that collision. (Pushing player out of the block) Note I used a 2D array to generate the world so it's only cubes that I have to check collision with.... if this is a bad question or am lacking something please tell me before you -rep me, am just not sure how to do this and google doesn't want to help

  • As a game developer, which data structure use for develop the game? [duplicate]

    - by Rizwanabbasi
    This question already has an answer here: When should vector/list be used? 5 answers We are developing a game for bank robbery. The game plots a bank robbery. Lots of people witness that robbery. Our game will load the lists of suspected offenders while the players (witnesses) will have to identify the offenders of this robbery. Game should load list of offenders to identify the one as quickly as possible. Admin can add/remove offenders in the lists and two or more lists of offenders can also be merged into one (to show it to the player). As a game developer, which data structure we should use for develop the game? Justify your selection with solid arguments. Remember the most critical requirement is that the list should load super fast.
