  • Looking to write a Tag class

    - by Austin Schneider
    I'm looking to write a Tag class (a tag is a string with no spaces). My first thought is to inherit from String: class Tag < String def initialize(str) raise ArgumentError if str =~ /\s/ super end end Does this look correct? Are there any other methods I should redefine?

  • How to create a registry key in 64bit view from a 32bit application, using native windows api.

    - by George Kas
    I'm kind of a noob when it comes to windows api. I try to create a registry key in the 64bit view of the registry, from a 32bit application using System::Call "${RegCreateKeyEx}(${HKEY_LOCAL_MACHINE}, 'SOFTWARE\SecureW2\Methods\Default\Profiles\26\ConfigData', 0, 'REG_BINARY', 0x00000000L, 0x0100, NULL, .r5, .r6) .r3" (it's nsis scripting), but it doesn't seem to work.

  • Is Zscalar's HTTPS Everywhere for IE affiliated with EFF?

    - by noloader
    The Electronic Frontier Foundation has a tool called HTTPS Everywhere for Firefox, Chrome and Opera. But they don't list Internet Explorer. There is a company called Zscalar that provides HTTPS Everywhere for Internet Explorer. I can't determine if the EFF approves of Zscalar's IE extension, or if the company hijacked the EFF tool's name. The only mention of Zscalar on the EFF website is the HTTPS Everywhere Atlas. The closest I can find from Zscalar are link backs on the Zscalar website and a Zscalar PDF that points back to the EFF website. The EFF tool is free, open source and can be audited, but I don't see similar governance for Zscalar's tool. For example, I don't see mention of source code at HTTPS Everywhere for Internet Explorer. And it looks like there's a "Free Trial" for HTTPS Everywhere for Internet Explorer (see the link on the right). Is Zscalar's HTTPS Everywhere for IE affiliated with EFF?

  • Better C# Syntax Coloring for Visual Studio 2010?

    - by Oak
    Coming from Eclipse, I'm disappointed with the very limited syntax coloring capabilities offered for C# by Visual Studio (all versions, up to 2010). In particular, I'm interesting in distinct coloring for methods / fields / locals / static stuff. I'm aware Visual Assist can enhance the coloring, but I've failed to find any free alternative capable of doing that, so I'm turning to SO (I hope it's programming-related enough). Is there any free (or at least cheaper than Visual Assist) solution capable of enhancing the syntax coloring for C#?

  • Spring MVC Best Practice Handling Unrecoverable Exceptions In Controller

    - by jboyd
    When you have a controller that does logic with services and DAO's that may throw an unrecoverable exception, what is the best practice in dealing with those method calls? Currently an app I'm working on has very lengthy try catch methods that simply err.out exception messages, this doesn't seem very robust and I think that this code smells, is there any cookie cutter best practice for handling this in spring-mvc?

  • How can I reverse connect with vncconnect or vncconfig with ubuntu as the server?

    - by yan bellavance
    On a windows machine I am running: "listening VNC viewer" From a Ubuntu machine, I need to reverse connect to the windows machine but it does not seem to be working. I was able to make it work between 2 windows machines, but I need it to work with Ubuntu as the server as well. I tried vncconnect -display $DISPLAY 192.168.1.134:5500 and nothing happens. So instead I tried vncconfig but I get the message : "No VNC extension on display :0.0" Any ideas? If this is the wrong site just send me a comment I'll close the question.

  • class composition instead of object composition?

    - by fayer
    I want a class property to be reference to another class, not its object and then use this property to call the class's static methods. class Database { private static $log; public static function addLog($LogClass) { self::$log = $LogClass; } public static function log() { self::$log::write(); // seems not possible to write it like this } } any suggestions how i can accomplish this? cause i have no reason making them objects, i want to use the classes for it.

  • MacBook not connecting anywhere via VPN

    - by Toby
    I was wondering if someone could help me troubleshoot this issue. I have a handful of VPNs set up on my MacBook (Snow Leopard) which I know are working, but today when I tried to use them I get the following error in all cases: could not find the PPP kernel extension I have not needed to use any VPN for a while but they have worked in the past and there is nothing I can think of that I have changed on this machine. I have looked in System/Library/Extensions and PPP.kext is there which is the file I thought it would be looking for? Any help would be greatly appreciated.

  • Core-Data + AFNetworking + UI Updating (Responsiveness)

    - by Mustafa
    Here's the scenario: I'm writing a DownloadManager, that allows the user to download, pause, cancel, download all, and pause all. The DownloadManager is a singleton, and uses AFNetworking to download files. It has it's own private managed object context, so that user can freely use other parts of the application (by adding, editing, deleting) core-data objects. I have a core-data entity DownloadInfo that stores the download information i.e. fileURL, fileSize, bytesRead, etc. The DownloadManager updates the download progress in DownloadInfo (one for each file). I have a DownloadManagerViewController which uses NSFetchedResultsController to show the download status to the user. This download view controller is using the main managed object context. Now let's say that I have 20 files in the download queue. And let's say that only 3 concurrent downloads are allowed. The download manager should download the file, and show the download progress. Problem: The DownloadInfo objects are being updated by the DownloadManager at a very high rate. The DownloadManagerViewController (responsible for showing the download progress) is updating the list using NSFetchedResultsControllerDelegate methods. The result is that a lot is happening in the main queue and application has very poor responsiveness. How can I fix this? How can I make the application responsive, while showing the download progress? I don't know how else to communicate that the download status between DownloadManager and DownloadManagerViewController. Is there another/ a better way to do this? I don't want to use main managed object context in my DownloadManager, for reasons mentioned above. Note, that the DownloadManager is using AFNetworking which is handling the requests asynchronously, but eventually the DownloadInfo objects are updated in the main thread (as a result of the callback methods). Maybe there's a way to handle the downloads and status update operations in a background thread? but how? How will I communicate between the main thread and the background thread i.e. how will I tell the background thread to queue another file for download? Thanks.

  • XNA MediaPlayer fastforward/rewind

    - by bufferz
    Using XNA 4.0, I am currently playing songs from the user's PC/XBox360 using the following: Microsoft.Xna.Framework.Media.MediaPlayer.Play(Song song); I see that MediaPlayer has a static Property PlayPosition that, as I've researched, used to be a get/set property, but it has been updated to get-only. Are there any other methods/tricks I can use to explicitly set the playing position of a currently playing song?

  • Bang Notation and Dot Notation in VBA and MS-Access

    - by Nitrodist
    While perusing an application that I'm documenting, I've run across some examples of bang notation in accessing object properties/methods, etc. and in other places they use dot notation for what seems like the same purpose. Is there a difference or preference to using one or the other? Some simple googling only reveals limited information on the subject with some people actually using it in opposite cases. Perhaps there is a coding standards section from MS somewhere that indicates the method of madness?

  • Hibernate - on the stack or on the heap?

    - by Stephano
    As a Java programmer, you usually keep two truths in your pocket: Instance variables and Objects lie on Heap. Local variables and methods lie on the Stack. Now that I use Hibernate in just about everything, I realize I'm not as sure of myself. Are there some good rules of thumb for using hibernate and knowing where your memory lives?

  • How to calculate the length of a Path2D in Java?

    - by Sanoj
    I have some paths represented by Path2D. The Path consist of multiple CubicCurve2D or Line2D segments that are connected to each other. I would like to calculate or get the length from the start to the end of a Path. How can I calculate it or get it? Is it possible? I have checked the API documentation, but couldn't find any useful methods.

  • How to play an MKV 3D side-by-side video?

    - by djechelon
    I have a video in Matroska format (MKV, file extension .mkv), 3D half-SBS, where the 1280x720 frame shows the left-eye frame on the left and the right-eye frame on the right. I don't have a 3DTV, but I have NVidia 3D Vision: I tried to open it with PowerDVD 10 with no result (program hangs). With the same PowerDVD, I tried to play the Avatar 3D trailer downloaded from YouTube (MP4 format), but it now shows it the two frames. PowerDVD 10 is advertised to support 3D and 3D Vision. Why can't I play these videos? NVidia Stereoscopic player plays the Avatar trailer fine, but it doesn't support MKV.

  • Increase text size in Ubuntu 10.04 due to having large resolution/monitors

    - by Sridhar Ratnakumar
    I have 24" dual monitors with 1920x1080 resolution on both of them. Consequently the text appears so small. I use the following text-intensive applications frequently: Web browser (Google Chrome) IDE (Komodo) Terminal (Gnome Terminal) Email (Thunderbird) I can configure text size on IDE, Terminal and Email. But for Chrome, it is not a good idea to set proportional font size because often one wants to see the entire (not just proportional fonts) site to be zoomed. So I am asking: Is it possible to increase DPI in Ubuntu (much like on Windows) so as to increase the text size across all apps? OR Is it possible to set permanent 'zoom' in Google Chrome, using a third-party extension maybe? I am using Ubuntu 10.04 (Lucid Lynx)

  • object array mobile development

    - by mixm
    Im currently creating a tile-based game for android. Using java via dalvik JVM. im fretting over a decision to represent objects in a particular map. should i use an id based map (2 dimensional integer array) and place game logic in a separate function in the game engine, or create an object array (2 dimensional array of game objects) and store game logic within the class methods. i am thinking about the cost of object creation and garbage collection vs extensibility.

Team Name - RushSoft Game Design Project Name - N/A We are gathering staff so that we can begin working on a new game. Target Aim - Freeware / Free Version - Paid Version With our first project our aim is to simply get our name out there. Generally we will be targeting a freeware distribution platform or a Free and Paid version. Compensation - Prehaps in the future but don't rely on it If in the future we start developing a game we intend to make any sort of sizable profit from then yes, there will be compensation however currently our low, low funding comes from generous donations. Any money that we make for now will go to the teams funding for things like engine licenses and company registration. Technology - C/C++ RSETech Our primary functional language will be C/C++ as most games are. We will be using a custom built library built on Direct3D called RSETech or RushSoft Engine Technology. Currently its is fully capable of being used for developing a game. The final version is made up of almost entirely C (No C++ or OOP). There is a C++ version currently in the works. Programming: - Microsoft Visual C++ 2008 / 2010 2D Art - Photoshop CS2 - GIMP Talent Needed - We currently are in need of x2 Programmers - With understanding of the following C/C ++ and game programming aspects: -If/Else Conditions -Functions/Methods -Arrays -Pointers (You don't need to fully understand these. Just know when they need to be used.) -Enums -Loops (For and While) -Structs (and How to use . and - syntax) -Classes (and how to call methods and access variables from a class) -State Machines -Switches -Include Guards -Understanding of how game loops work in general. (Init, Update, Render, Deinit) x2 Artists - As long as you have the means to and are able to draw 2D sprites and collab with a game designer to get a good result. 1 or more Game Designers - You can design levels (for platformers) as well as write game scripts and you can come up with good ideas and game mechanics. As long as you can do these things and are able to work well with artists and programmers you're golden. Business Consultant - Someone who knows the industry and how it works. Will inquire about possible distribution platforms as well as contact other developers, websites, and publishers on RushSofts behalf.

  • NSDocument Subclass not closed by NSWindowController?

    - by Nathan Douglas
    Okay, I'm fairly new to Cocoa and Objective-C, and to OOP in general. As background, I'm working on an extensible editor that stores the user's documents in a package. This of course required some "fun" to get around some issues with NSFileWrapper (i.e. a somewhat sneaky writing and loading process to avoid making NSFileWrappers for every single document within the bundle). The solution I arrived at was to essentially treat my NSDocument subclass as just a shell -- use it to make the folder for the bundle, and then pass off writing the actual content of the document to other methods. Unfortunately, at some point I seem to have completely screwed the pooch. I don't know how this happened, but closing the document window no longer releases the document. The document object doesn't seem to receive a "close" message -- or any related messages -- even though the window closes successfully. The end result is that if I start my app, create a new document, save it, then close it, and try to reopen it, the document window never appears. With some creative subclassing and NSLogging, I managed to figure out that the document object was still in memory, and still attached to the NSDocumentController instance, and so trying to open the document never got past the NSDocumentController's "hmm, currently have that one open" check. I did have an NSWindowController and NSDocumentController instance, but I've purged them from my project completely. I've overridden nearly every method for NSDocument trying to find out where the issue is. So far as I know, my Interface Builder bindings are all correct -- "Close" in the main menu is attached to "performClose:" of the First Responder, etc, and I've tried with fresh unsullied MainMenu and Document xibs as well. I thought that it might be something strange with my bundle writing code, so I basically deleted it all and started from scratch, but that didn't seem to work. I took out my init method overrides, and that didn't help either. I don't have the source of any simple document apps here, so I didn't try the next logical step (to substitute known-working code for mine in the readfromurl and writetourl methods). I've had this problem for about sixteen hours of uninterrupted troubleshooting now, and needless to say, I'm at the end of my rope. If I can't figure it out, I guess I'm going to try the project from scratch with a lot more code and intensity based around the bundle-document mess. Any help would be greatly appreciated.

  • HttpURLConnection: Is it necessary to call connect()?

    - by stormin986
    Many examples I've seen don't explicitly call connect(). Instead they just use getInputStream() or getResponseCode(). I'm assuming all of these HttpURLConnection methods that require a connection just call connect() themselves? Are there any cases where connect() must be explicitly called for an HttpURLConnection?
