  • Good Introductory Books on Writing Secure Software

    - by cosmic.osmo
    What are some good introductory books about writing secure software? Specifically, one that covers basic strategies and design patterns for writing a secure software and surveys common security vulnerabilities, how they're exploited, and how you can protect against them. Personally, I've picked up bits of security know-how here and there over my career, but now I'd like a more systematic overview.

  • Should iOS games use a Timer?

    - by ????
    No matter what frameworks we use -- Core Graphics, Cocos2D, OpenGL ES -- to write games, should a timer be used (for games that has animation even when a user doesn't do any input, such as after firing a missile and waiting to see if the UFO is hit)? I read that NSTimer might not get fired until after scheduled time (interval), and CADisplayLink can delay and get fired at a later time as well, only that it tells you how late it is so you can move the object more, so it can make the object look like it skipped frame. Must we use a Timer? And if so, what is the best one to use?

  • How should game objects be aware of each other?

    - by Jefffrey
    I find it hard to find a way to organize game objects so that they are polymorphic but at the same time not polymorphic. Here's an example: assuming that we want all our objects to update() and draw(). In order to do that we need to define a base class GameObject which have those two virtual pure methods and let polymorphism kicks in: class World { private: std::vector<GameObject*> objects; public: // ... update() { for (auto& o : objects) o->update(); for (auto& o : objects) o->draw(window); } }; The update method is supposed to take care of whatever state the specific class object needs to update. The fact is that each objects needs to know about the world around them. For example: A mine needs to know if someone is colliding with it A soldier should know if another team's soldier is in proximity A zombie should know where the closest brain, within a radius, is For passive interactions (like the first one) I was thinking that the collision detection could delegate what to do in specific cases of collisions to the object itself with a on_collide(GameObject*). Most of the the other informations (like the other two examples) could just be queried by the game world passed to the update method. Now the world does not distinguish objects based on their type (it stores all object in a single polymorphic container), so what in fact it will return with an ideal world.entities_in(center, radius) is a container of GameObject*. But of course the soldier does not want to attack other soldiers from his team and a zombie doesn't case about other zombies. So we need to distinguish the behavior. A solution could be the following: void TeamASoldier::update(const World& world) { auto list = world.entities_in(position, eye_sight); for (const auto& e : list) if (auto enemy = dynamic_cast<TeamBSoldier*>(e)) // shoot towards enemy } void Zombie::update(const World& world) { auto list = world.entities_in(position, eye_sight); for (const auto& e : list) if (auto enemy = dynamic_cast<Human*>(e)) // go and eat brain } but of course the number of dynamic_cast<> per frame could be horribly high, and we all know how slow dynamic_cast can be. The same problem also applies to the on_collide(GameObject*) delegate that we discussed earlier. So what it the ideal way to organize the code so that objects can be aware of other objects and be able to ignore them or take actions based on their type?

  • Some Facebook Pages Show Tabs On The Top Of Page, And Others On The Left. Why?

    - by mickburkejnr
    Hi everyone, I am developing a Facebook page for my web design/development business, and I've noticed that the page I have created has the tabs aligned to the left hand side of the page underneath the page image. I then look at other pages such as Wetherspoons and Porsche and their tabs are aligned to the top of the page. Why is it like this? Is there a configuration I've missed that allows you to change the layout of the tabs? Cheers!

  • Unintentional run-in with C# thread concurrency

    - by geekrutherford
    For the first time today we began conducting load testing on a ASP.NET application already in production. Obviously you would normally want to load test prior to releasing to a production environment, but that isn't the point here.   We ran a test which simulated 5 users hitting the application doing the same actions simultaneously. The first few pages visited seemed fine and then things just hung for a while before the test failed. While the test was running I was viewing the performance counters on the server noting that the CPU was consistently pegged at 100% until the testing tool gave up.   Fortunately the application logs all exceptions including those unhandled to the database (thanks to log4net). I checked the log and low and behold the error was:   System.ArgumentException: An item with the same key has already been added. (The rest of the stack trace intentionally omitted)   Since the code was running with debug on the line number where the exception occured was also provided. I began inspecting the code and almost immediately it hit me, the section of code responsible for the exception is trying to initialize a static class. My next question was how is this code being hit multiple times when I have a rudimentary check already in place to prevent this kind of thing (i.e. a check on a public variable of the static class before entering the initializing routine). The answer...the check fails because the value is not set before other threads have already made it through.   Not being one who consistently works with threading I wasn't quite sure how to handle this problem. Fortunately a co-worker recalled having to lock a section of code in the past but couldn't recall exactly how. After a quick search on Google the solution is as follows:   Object objLock = new Object(); lock(objLock) { //logic requiring lock }   The lock statement takes an object and tells the .NET runtime that the current thread has exclusive access while the code within brackets is executing. Once the code completes, the lock is released for another thread to utilize.   In my case, I only need to execute the inner code once to initialize my static class. So within the brackets I have a check on a public variable to prevent it from being initialized again.

  • Part 5: Choose the right tool - or - why

    - by volker.eckardt(at)oracle.com
    Consider the following client request “Please create a report for us to list expenses”. Which Oracle EBS tool would you choose? There are plenty of options available: Oracle Reports, or BI Publisher with PDF or Excel layout, or Discoverer, or BI Publisher Stand Alone, or PDF online generation, or Oracle WebADI, or Plain SQL*Plus as Concurrent Program, or Online review option … Assuming, you as development lead have to decide, you may decide by available skill set in your development team. However, is this a good decision? An important question to influence the decision is the “Why” question: why do you need this report, what process is behind, what exactly you like to achieve? We see often data created or printed, although it would be much better to get the data in Excel, and upload changes via WebADI directly. There are more points that should drive your decision: How many of such requirements you have got? Has this technique been used in the project already? Are there related reusable’s you may gain from? How difficult is it to maintain your solution? Can you merge this report with another one, to reduce test and maintenance work? In addition, also your own development standards should guide you a bit to come to a good decision. In one of my own projects, we discussed such topics in our weekly team meeting. By utilizing the team knowledge best, you may come to a better decision, and additionally, your team supports your decision. Unfortunately, I have rarely seen dedicated team trainings or planned knowledge transfer to support such processes. Often the pressure to deliver on time is too high to have discussion and decision time left. But exactly this can help keeping maintenance costs low by limiting the number of alternative solutions for similar requirements. Lastly, design decisions should be documented to allow another person taking this over easily. Decisions shall be reviewed and updated regularly, to reflect related procedures or Oracle products respective product versions. Summary: Oracle EBS offers plenty of alternatives to implement customizations. Create and maintain a decision tree to support the design process. Do not leave the decision just on developer side. Limit the number of alternative solutions as best as possible; choose one which is the most appropriate also from future maintenance perspective.

  • Windows 8 Location Services

    - by ryanabr
    I spent the afternoon with the Geolocator object in the WinRT and Widows 8 platform. I have also been working with doing Windows Phone 7 development, and first had to wrap my head around the fact that while similar, it is not the same as the GeoCoordinateWatcher that environment. I found a nice example here http://code.msdn.microsoft.com/windowsapps/Geolocation-2483de66 But the behavior of my app wasn’t the same. Once you ensure that location services is enabled by following these instructions: http://msdn.microsoft.com/en-us/library/windows/desktop/hh768219.aspx Location Services was still disabled. From everything I read, it sounded like the first time you try to use the Geolocator object, the user would be prompted to allow to “Access to your location”. After nosing around I found the issue. You need to add the location service as a Capability in the Package.appxmanifest file: After checking the box, I was prompted to allow access to location services as expected the first time I needed to use it.

  • Do you prefer building your interfaces in IB or programmatically? and why?

    - by LolaRun
    I've been using Xcode and building iPhone apps for two months, but I'm finding it really hard to grasp good application design. I always face problems—like you can't put your tabbarcontroller in another custom viewcontroller, for example—that 'sometimes', of course, would work if you did the creation of the views/viewcontrollers programmatically. So I don't know if I should start writing the creation of my objects or use Interface Builder. What are your experiences?

  • Using VBA to model data in Autodesk Inventor?

    - by user108478
    I have a close friend who is using a specific device that records the dimensions of an object as it is eroded and outputs the dimensional data to an excel sheet. The object is spherical in nature but is eroded from the top and bottom, so the shape is constantly changing and a single formula for surface area and volume would not work. This is where Inventor comes in. My friend can plug the dimensional data to Inventor and it immediately returns the surface area and volume. The erosion process takes several minutes to complete and records data at very short intervals, so it would be very arduous to plug in the data thousand of time. Since Inventor supports macros and VBA, is there a way to plug the data into Inventor and output it into another spreadsheet? Any suggestions would be appreciated.
