• Does it make sense to implement OAuth for a 2 party system?

  - by nbv4

  I'm under the impression that OAuth is for authentication between three parties. Does it make sense to implement OAuth in a context where there is just a client and server. We have a server, and a client (HTML/javascript). Currently we authenticate via the normal "post credentials to server, get a cookie, use cookie to authenticate all subsequent requests" method. Will implementing OAuth be a benefit in this situation?

• Improving the performance of JDeveloper11g (part 2) and JVMs in general

  - by asantaga

  Just received an email from one of our JVM developers who read my blog entry on Performance tuning JDeveloper11g and he's confirmed that all of the above parameters are totally supported :-) He's also provided a description of the parameters so we can learn what magic is actually being applied. - -XX:+AggressiveOpts -- this enables the latest and greatest JVM optimizations. It will likely help most Java applications. It's fully supported. The downside of it is that because it has the latest and greatest optimizations, there is some small probability that it may not offer as good of an experience. As those features enabled with this command line option have "matured", they are made the default in a future JDK release. So, you can think of this command line option as the place where the newest optimizations get introduced. Some time later they are moved out from under AggressiveOpts to become default behavior. -XX:+OptimizeStringConcat -- only works with the -server JVM. It may be enabled by the default in a future JDK 7 update release. This option delays the construction of a StringBuilder/StringBuffer and attempts to avoid re-sizing the underlying char[] by attempting to detect the size of the char[] to allocate based on what's being appended to the StringBuilder/StringBuffer. -XX:+UseStringCache -- I would not suggest using this unless you knew that JDeveloper allocated the same string over and over again. And, the string that's allocated over and over again is one of the first 100,000 allocated strings. In short, I'd recommend against using it. And, in fact, in Java 7 (currently) does not include this feature. -XX:+UseCompressedOops -- applicable to 64-bit JVMs. And, if you're using a 64-bit JVM, I'd suggest you use it. It's auto enabled in JDK 7 64-bit JVMs and later JDK 6 64-bit JVMs enable it by default too. -XX:+UseGCOverheadLimit -- by default this option is already enabled. One other command line option to consider is -XX:+TieredCompilation for a JDK 6 Update 25 or later, or JDK 7. This gives you the startup of a -client JVM and the peak performance of a -server JVM. Awesome-ness!  Finally, Charlies also pointed out to me a "new" book he's just published where he goes into the details of JVM tuning, a must for all Fusion Middleware tuning exercises..  (click the book)  Thanks Charlie!

• How do I get a Canon MF4150 printer working?

  - by user31208

  As I am enjoying my new Ubuntu 11.10 OS (and impressed with it) I ran to some difficulty getting my Canon MF4150 printer to work. The printer seems installed properly (followed this post) however when I try to print something I get this error: printer-state-message="/usr/lib/cups/filter/pstoufr2cpca failed" I think I've come across the solution but I don't know how to apply it to my version of Ubuntu. Any ideas?

  i'm created isometric map and now trying to limit layer moving.

• Behavior Trees and Animations

  - by Tom

  I have started working on the AI for a game, but am confused how I should handle animations. I will be using a Behavior Tree for AI behavior and Cocos2D for my game engine. Should my "PlayAnimationWalk" just be another node in the tree? Something similar to this: [Approach Player] - Play Walk animation - Move Towards player - Stop Walk animation Or should the node just update an AnimationState in the blackboard and have some type of animation handler/component reference this for which animation should be playing? This has been driving me nuts :)

• What's the problem with Scala's XML literals?

  - by Oak

  In this post, Martin (the language's head honcho) writes: [XML literals] Seemed a great idea at the time, now it sticks out like a sore thumb. I believe with the new string interpolation scheme we will be able to put all of XML processing in the libraries, which should be a big win. Being interested in language design myself, I'm wondering: Why does he write that it was a mistake to incorporate XML literals into the language? What is the controversy regarding this feature?

• Avoid SQL Injection with Parameters

  - by simonsabin

  The best way to avoid SQL Injection is with parameters. With parameters you can’t get SQL Injection. You only get SQL Injection where you are building a SQL statement by concatenating your parameter values in with your SQL statement. Annoyingly many TSQL statements don’t take parameters, CREATE DATABASE for instance, or really annoyingly ALTER USER. In these situations you have to rely on using QUOTENAME or REPLACE to avoid SQL Injection. (Kimberly Tripp takes about this in her recent blog post Little...(read more)

• Bootloader Problems Grub Won't Load Windows 7

  - by user108805

  I sent this to [email protected], still no response thought I could get a faster solution here. I am running Windows 7 64-bit and Ubuntu 12.04 LTS on separate partitions. The message is sent is: Boot-Repair URL: http://paste.ubuntu.com/1365163/ Originally I was unable to access Ubuntu after a windows update (Ubuntu was installed using wubi). Rather than logging into Ubuntu from the Windows 7 Bootloader, it lead to the grub command prompt. No matter what I did here, it would not log me into linux. As a result I uninstalled Ubuntu from the Add/Remove Programs application in Windows 7. I then re-installed Ubuntu 12.04 LTS using a liveCD-USB. This time however, I created a partition. I then restarted and got the GRUB bootloader which loads Ubuntu 12.04 LTS with no problems, however when I select windows (listed as "Windows 7 (loader)"), it just refreshes the grub bootloader instead of loading Windows 7. I then used the Windows 7 repair disk to run bootrec/fixmbr and bootrec/fixboot. This led to no bootloader coming up when I started my computer. Instead I got a blank black screen with a flashing white cursor. I went on to do a bootrec/buildbcd and bootrec/scanos. These did nothing to change the situation. When I ran bootrec/scanos it said that no Windows 7 installations were present. After this I decided to reinstall WIndows 7 only for this to do nothing to change the situation. Afterwards I did a boot-repair in which I began to get the GRUB bootloader, which would load ubuntu 12.04 LTS, but still would not load Windows 7. I also did a sudo update-grub which recognized Windows 7 as being installed, but still didn't fix the issue of loading Windows 7. While running Ubuntu I have no problem accessing my WIndows 7 partition which is formatted as NTFS. It shows all the files and folders reflecting that the re-install did take place, and it also shows all of my old applications and folders in the Windows.old folder. I am completely stuck at this point and have no clue what I should do next. Any help you can offer me will be greatly appreciate. Thank You --gap

• 2-d lighting day/night cycle

  Off the back of this post in which I asked two questions and received one answer, which I accepted as a valid answer. I have decided to re-ask the outstanding question. I have implemented light points with shadow casting as shown here but I would like an overall map light with no point/light source. The map setup is a top-down 2-d 50X50 pixel grid. How would I go about implementing a day/night cycle lighting across a map?

• What is a good strategy for binding view objects to model objects in C++?

  - by B.J.

  Imagine I have a rich data model that is represented by a hierarchy of objects. I also have a view hierarchy with views that can extract required data from model objects and display the data (and allow the user to manipulate the data). Actually, there could be multiple view hierarchies that can represent and manipulate the model (e.g. an overview-detail view and a direct manipulation view). My current approach for this is for the controller layer to store a reference to the underlying model object in the View object. The view object can then get the current data from the model for display, and can send the model object messages to update the data. View objects are effectively observers of the model objects and the model objects broadcast notifications when properties change. This approach allows all the views to update simultaneously when any view changes the model. Implemented carefully, this all works. However, it does require a lot of work to ensure that no view or model objects hold any stale references to model objects. The user can delete model objects or sub-hierarchies of the model at any time. Ensuring that all the view objects that hold references to the model objects that have been deleted is time-consuming and difficult. It feels like the approach I have been taking is not especially clean; while I don't want to have to have explicit code in the controller layer for mediating the communication between the views and the model, it seems like there must be a better (implicit) approach for establishing bindings between the view and the model and between related model objects. In particular, I am looking for an approach (in C++) that understands two key points: There is a many to one relationship between view and model objects If the underlying model object is destroyed, all the dependent view objects must be cleaned up so that no stale references exist While shared_ptr and weak_ptr can be used to manage the lifetimes of the underlying model objects and allows for weak references from the view to the model, they don't provide for notification of the destruction of the underlying object (they do in the sense that the use of a stale weak_ptr allows for notification), but I need an approach that notifies the dependent objects that their weak reference is going away. Can anyone suggest a good strategy to manage this?
