  • Capitalization of Person names in programming

    - by Albert
    Hey all, Is anyone aware of some code/rules on how to capitalize the names of people correctly? John Smith Johan van Rensburg Derrick von Gogh Ruby de La Fuente Peter Maclaurin Garry McDonald (these may not be correct, just some sample names and how the capitalization could be/work) This seems like a losing battle... If anyone has some code or rules on when and how to capitalize names, let me know :) Cheers, Albert

  • Aspect oriented Programming?

    - by Jaswant Agarwal
    How can we apply attributes to class fucntion using AOP in C#? UPDATE: I am slightly not clear in what context AOP should be used? As we can use AOP for logging purpose, security(Authentication), please suggest some other scenarios where we can take benefit of AOP Is AOP can be use to share data among different running threads in application process?

  • Programming Related Songs

    - by Jim McKeeth
    One song per answer please! We have discussed music you listen to while coding, but I looking for music related to coding and coders. It can be eclectic or mainstream, and even a bit of a stretch (just explain the connection). Vote for your favorite song or add it if it isn't already here. Link to lyrics, band, music, video, etc., when possible.

  • iPhone programming - problem with CoreFoundation forking

    - by Tom
    Hello all, I've been working on an iPhone for several months. It's a 2d shooting game akin to the old Smash TV type games. I'm doing everything alone and it has come out well so far, but now I am getting unpredictable crashes which seem to be related to CoreFoundation forking and not exec()ing, as the message __THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONA LITY___YOU_MUST_EXEC__ always shows up somewhere in the debugger. Usually it shows up around a CFRunLoopRunSpecific and is related to either a timer firing or _InitializeTouchTapCount. I cannot figure out exactly what is causing the fork to occur. My main game loop is running on a timer, first updating all the logic and then drawing everything with openGL. There is nothing highly complex or unusual. I understand you cannot make CF calls on the childside of a fork, or access shared memory and things like that. I am not explicitly trying to fork anything. My question is: can anyone tell me what type of activity might cause CoreFoundation to randomly fork like this? I'd really like to finish this game and I don't know how to solve this problem. Thanks for any help.

  • AOP programming in .Net?

    - by larryq
    Hi everyone, I'm wondering what's good out there for AOP / crosscutting in .Net, along the lines of AspectJ. I see Microsoft has a policy injection application block; any other good stuff out there I should take a look at?

  • In your experience, what has inspired you to change a fundamental programming tool

    - by Dr J
    A lot of what I am working on is changing the mindset of a community of developers. Moving them from one tool to another, or to picking up a new tool. What are some of the suggested or recommended ways to get a community to pick up a new meme? While we can mandate tool usage, this is a last resort. I would rather have the developers move to any new tools of their own accord. I'm not a programmer, I need to understand why a programmer will move from one tool to another. Edited the title thanks to a fabulous comment! My world runs on Meme's, tipping points, and general pressures. This is why I needed to ask. And clarifying yet more- I am the middle manager needing to plan and manage an implementation and not a sales person.

  • SSD and programming

    - by Simon Johnson
    I'm trying to put together a business case for getting every developer in our company an Intel SSD drive. The main codebase contains roughly 400,000 lines of code. My theory is that since the code is scattered about in maybe 1500 files, an SSD drive would be substantially faster for compiles. The logic being that many small reads really punishes the seak-time bottle-neck of a traditional hard-drive. Am I right? Is SSD worth the money in productivity gains by reducing the edit/compile cycle time?

  • 'echo' or drop out of 'programming' write HTML then start PHP code again

    - by thecoshman
    For the most part, when I want to display some HTML code to be actually rendered I would use a 'close PHP' tag, write the HTML, then open the PHP again. eg <?php // some php code ?> <p>HTML that I want displayed</p> <?php // more php code ?> But I have seen lots of people who would just use echo instead, so they would have done the above something like <?php // some php code echo("<p>HTML that I want displayed</p>"); // more php code ?> Is their any performance hit for dropping out and back in like that? I would assume not as the PHP engine would have to process the entire file either way. What about when you use the echo function in the way that dose not look like a function, eg echo "<p>HTML that I want displayed</p>" I would hope that this is purely a matter of taste, but I would like to know if I was missing out on something. I personally find the first way preferable (dropping out of PHP then back in) as it helps draw a clear distinction between PHP and HTML and also lets you make use of code highlighting and hinting for your HTML, which is always handy.

  • physics game programming box2d - orientating a turret-like object using torques

    - by egarcia
    This is a problem I hit when trying to implement a game using the LÖVE engine, which covers box2d with Lua scripting. The objective is simple: A turret-like object (seen from the top, on a 2D environment) needs to orientate itself so it points to a target. The turret is on the x,y coordinates, and the target is on tx, ty. We can consider that x,y are fixed, but tx, ty tend to vary from one instant to the other (i.e. they would be the mouse cursor). The turret has a rotor that can apply a rotational force (torque) on any given moment, clockwise or counter-clockwise. The magnitude of that force has an upper limit called maxTorque. The turret also has certain rotational inertia, which acts for angular movement the same way mass acts for linear movement. There's no friction of any kind, so the turret will keep spinning if it has an angular velocity. The turret has a small AI function that re-evaluates its orientation to verify that it points to the right direction, and activates the rotator. This happens every dt (~60 times per second). It looks like this right now: function Turret:update(dt) local x,y = self:getPositon() local tx,ty = self:getTarget() local maxTorque = self:getMaxTorque() -- max force of the turret rotor local inertia = self:getInertia() -- the rotational inertia local w = self:getAngularVelocity() -- current angular velocity of the turret local angle = self:getAngle() -- the angle the turret is facing currently -- the angle of the like that links the turret center with the target local targetAngle = math.atan2(oy-y,ox-x) local differenceAngle = _normalizeAngle(targetAngle - angle) if(differenceAngle <= math.pi) then -- counter-clockwise is the shortest path self:applyTorque(maxTorque) else -- clockwise is the shortest path self:applyTorque(-maxTorque) end end ... it fails. Let me explain with two illustrative situations: The turret "oscillates" around the targetAngle. If the target is "right behind the turret, just a little clock-wise", the turret will start applying clockwise torques, and keep applying them until the instant in which it surpasses the target angle. At that moment it will start applying torques on the opposite direction. But it will have gained a significant angular velocity, so it will keep going clockwise for some time... until the target will be "just behind, but a bit counter-clockwise". And it will start again. So the turret will oscillate or even go in round circles. I think that my turret should start applying torques in the "opposite direction of the shortest path" before it reaches the target angle (like a car braking before stopping). Intuitively, I think the turret should "start applying torques on the opposite direction of the shortest path when it is about half-way to the target objective". My intuition tells me that it has something to do with the angular velocity. And then there's the fact that the target is mobile - I don't know if I should take that into account somehow or just ignore it. How do I calculate when the turret must "start braking"?

  • Specific programming text editor for simple open/close editing

    - by queen3
    I'm looking for very specific text editor: Closes on ESC, no project management or tabs Syntax highlighting - preferably with color themes (e.g. can apply different color themes without changing C# coloring definition) or, at least, can load/save themes; support for C/C#/XML/HTML/JavaScript/etc - common MS/.NET world - out of box Configurable keys, or: Shift-Tab shifts blocks XML/HTML auto-completion support - well, optional I use synplus plugin for Total Commander currently, but it has few drawbacks (e.g. crashes sometimes ;-), no auto-completion, etc). Basically I want fast Visual-Studio-like editor that I open, do edits, and then close using ESC. I remember I tried Notepad++, etc - most of them open files in tabs, don't close on ESC... - that is, behave like IDE. At least I've just downloaded Notepad++, it doesn't close on ESC even if I setup keybindings to do so. Autocompletion is optional (though it is to be simple as just tags completion), what I really look for is closing on ESC, not getting in the way with all the tabs and IDE-like, and good coloring. Plus shift-tab is must have for blocks manipulation. Update: any open-source one that I can easily tweak to close on ESC? ;-) Seems like ESC (and reasonable color highlighting) is the core requirement. I've just tried many editors - Programmer's Notepad, E, Crimson, etc - I can't set any of them to close on ESC. Any external tool to close selected program on ESC? ;-) UPDATE: Hm, found an awesome utility for my latest thought: http://www.autohotkey.com. Easy to setup to close any window on ESC (as well as many other tricks). Seems like the most tough requirements is gone - I can use ANY text editor ;-)

  • Programming an Event listener for files in a directory on Linux

    - by Epitaph
    On Ubuntu linux, when you watch a flash video, it gets saved temporarily in the /tmp as flv files while the video buffers. I use vlc to directly play these files. Currently, I have scripted a shortcut that directly scans and opens the latest file in /tmp with vlc, when clicked. But, I want to program a Java application that will continually monitor this /tmp directory for any new flv files, and open it in vlc automatically. I know I can use Runtime.exec() to open the VLC application with the flv files. But, I DO NOT want to run a while(true) loop (with sleep) to scan for files. How can I make use of Event Handling (Java or any other language) on Linux to complete this task?

  • Scala Programming for Android

    - by Lemmy
    I have followed the tutorial at Scala and Android with Scala 2.7.3 final. The resulting Android App works but even the most basic application takes several minutes (!) to compile and needs 900 kb compressed, which is a show stopper for mobile applications. Additionally, the IDE runs out of memory every now and then. I assume dex is not made for big libraries like the scala-library. So my question is: Has anyone actually done this and is there any cure for this?

  • Programming a windows service

    - by xarzu
    I have started prgramming a windows service. I have added a notify icon from the toolbox. It has the small notify icon that appears in the systray as a member of those icons. It works so far. So far I have a blank form. I have used the DoubleClick for the notifyIcon to bring up the form (I will use the form for something later). Now I have a list of things I want to accomplish to make this work like a true windows service. First of all, if possible, I owuld like to remove the maximize and cancel button on the form. Most windos service apps that I have seen offer the ability to close the app by right-mouse-button clicking on the notify icon which brings up a menu of options. I see in the properties of the form under Misc there is an CancelButton. But I do not see how do deactivate it. In the Properties of the forum I see under Window Style there is a ControlBox option that, if I turn to false, all three buttons, (minimize, maximize and cancel) go away. These are not what i am looking for. I would not like the option for them to resize, maximize or close the form here. I suspect people will close the box intending to make the box go away while still wanting the app to run. Under the "Focus" caption in Properties, there id "Deactivate". I have created my own event/method/function for this and in debug I noticed that when you click on the x-box in the upper right corner, this function is called. The problem is that after the function is over, the app closes anyway. How do I over-ride this function? Secondly, how do you catch the right button click event on the notify icon in the systray? I can see how to create events for "Click" and "MouseClick" etc. but how so I determine which button was click? Using the right buton click is how such programs know when to pull up a menu. So I would like to know how to do this as well.

  • Netlogo Programming question - Chemical Equilibrium temperature and pressure implementation

    - by user286190
    Hi I am trying to code something in Netlogo..I am using an existing model Chemical Equilibrium and am trying to implement the following: turtles-own [speed ] ask turtles [ ;; set velocity ( ambient-temperature = 30 ) ;; fd velocity if temp > 40 [ "speed" increases of turtles ] ifelse temperature < 30 [ speed of turtles decreases] ] ;; to temp but it does not seem to work (it temperature is more than 40 the speed of the turtles increases if the temperature is less than 30 the speed of the turtles decreases) temperature is a slider on the model the same for pressure ask turtles [ ;; if pressure > 50 then speed increases of turtles ;; if pressure < 50 then speed decreases of turtles ] ;; to pressure thanks
