• Mobile cross-platform SDK for computationally intensive apps

  - by K.Steff

  I am aware of the PhoneGap toolkit for creating mobile applications for virtually all mobile platforms with a significant market share. However, the code in PhoneGap that is shared between the different platforms is written in JavaScript. While I like JS, I think it's hardly appropriate for computationally intensive tasks. The situation with Titanium is pretty much the same. So, is there any way that I can create a cross-platform mobile app that has the computationally intensive code shared between the platforms? Some context: Obviously, I don't want to implement the time consuming algorithm in many different languages, since this violates DRY, increases the chance for bugs slipping in at least one version and require boilerplate code to work. I've looked at Xamarin's MonoTouch and Mono for Android tools, but while they cover iOS and Android, they're not nearly as versatile for deployment as PhoneGap. On the other hand, (IMO) the statically typed nature of C# is more suited for intense computation than JS. Are there any other SDK/tools appropriate for the task that I don't know about or a point about the mentioned above that I've missed? Also, uploading data to a web service for processing is not an option, because of the traffic required.

• How to maintain symlinks in linux file manager?

  - by MountainX

  I want to use symlinks extensively. However, if I move the target file, the symlink becomes broken (unlike on Windows). That's not acceptable to me, so I either need a solution or I won't be able to use symlinks the way I wish to. Is there a solution that will work with Dolphin file manager? A command line solution is described on commandlinefu. In summary, it is something like one of these: lmv(){for a in ${@:1:$(expr $#-1)};do [ -e "$a" -a -e "${@:$#:1}" ] && mv "$a";"${@:$#:1}" && ln -s "${@:$#:1}"/"$(basename "$a")";"$(dirname "$a")";done} lmv(){for a in ${@:1:$(expr $#-1)};do [ -e "$a" -a -e "${@:$#}" ] && mv "$a";"${@:$#}" && ln -s "${@:$#}"/"$(basename "$a")";"$(dirname "$a")";done} But about half the time I'm using a file manager (Dolphin), so I need a complete solution to this problem. Is a solution available for a GUI file manager? EDIT: The context of this question is that I'm searching for an alternative to hardlinks. I previously asked this question about the pitfalls of hardlinks.

• Starting an HTML canvas game with no graphics skills

  - by Jacob

  I want to do some hobby game development, but I have some unfortunate handicaps that have me stuck in indecision; I have no artistic talent, and I also have no experience with 3D graphics. But this is just a hobby project that might not go anywhere, so I want to develop the stuff I care about; if the game shows good potential, my graphic "stubs" can be replaced with something more sophisticated. I do, however, want my graphics engine to render something approximate to the end goal. The game is tile-based, with each tile being a square. Each tile also has an elevation. My target platform (subject to modification) is JavaScript rendering to the HTML 5 canvas, either with a 2D or WebGL context. My question to those of you with game development experience is whether it's easier to develop an isometric game using a 2D graphics engine and sprites or a 3D game using rudimentary 3D primitives and basic textures? I realize that there are limitations to isometric projection, but if it makes developing my throwaway graphics engine easier, I'm OK with the visual warts that would be introduced. Or is representing a 3D world with an actual 3D engine easier?

• How can player actions be "judged morally" in a measurable way?

  - by Sebastien Diot

  While measuring the player "skills" and "effort" is usually easy, adding some "less objective" statistics can give the player supplementary goals, especially in a MUD/RPG context. What I mean is that apart from counting how many orcs were killed, and gems collected, it would be interesting to have something along the line of the traditional Good/Evil, Lawful/Chaotic ranking of paper-based RPG, to add "dimension" to the game. But computers cannot differentiate good/evil effectively (nor can humans in many cases), and if you have a set of "laws" which are precise enough that you can tell exactly when the player breaks them, then it generally makes more sense to actually prevent them from doing that action in the first place. One example could be the creation/destruction axis (if players are at all allowed to create/build things), possibly in the form of the general effect of the player actions on "ecology". So what else is there left that can be effectively measured and would provide a sense of "moral" for the player? The more axis I have to measure, the more goals the player can have, and therefore the longer the game can last. This also gives the players more ways of "differentiating" themselves among hordes of other players of the same "class" and similar "kit".

• Upgrade from Linux Mint 12 to Kubuntu 12.04?

  - by MountainX

  Is there an "easy" way to "upgrade" my existing Linux Mint 12 install to Kubuntu 12.04 beta 2? I know I could reinstall. Usually I would do a clean install to avoid unexpected issues. But in this case, I don't have time to reconfigure everything from my printers to my installed software, so I am looking for the quick/easy way, but I also want to avoid big risks of an upgrade gone wrong. I'm hoping to just change some repos and run a few commands from the terminal. I don't mind editing a few config files as long as I can find good HOWTOs. But I don't want to be the pioneer (arrows in back). I'm hoping someone has done this before and has a set of steps. For context, I recently installed KDE 4.8 SC onto Kubuntu 11.10 using PPAs. This was on another computer. That wasn't a problem. But I decided to do a fresh install of Kubuntu 12.04 later. I like it well enough that I want to change my other computer from Linux Mint 12 to Kubuntu. (I'm going all-in with KDE. It's now my desktop of choice.) This Linux Mint upgrade will be a move from Gnome and MGSE to KDE, so that will probably complicate things at bit compared to something like upgrading Kubuntu 11.10 to KDE 4.8. References: http://www.psychocats.net/ubuntu/kde Is it safe to install Kubuntu-desktop in 11.10?

• Wordnik Accelerator

  - by prabhpreet

  Wow, creating IE Accelerators is superbly easy. If you want to learn how to create one, go here (some MSDN blog) and the MSDN documentation (clearly written). I was fed up of dictionary.com bringing all those popups and the stupid definitions of Google's dictionary. So I decided to scratch my own itch. I randomly stumbled on the site called Wordnik and it provides with all examples plus definitions plus lots more for words and its popup-free (as far as I know). So I decided to write and accelerator. Here is the source code (Yes, this is it): <?xml version="1.0" encoding="utf-8"?> <os:openServiceDescription xmlns:os="http://www.microsoft.com/schemas/openservicedescription/1.0"> <os:homepageUrl>http://www.wordnik.com</os:homepageUrl> <os:display> <os:name>View on Wordnik</os:name> <os:description>Looking up words on an awesome word site called Wordnik </os:description> <os:icon>http://www.wordnik.com/favicon.ico</os:icon> </os:display> <os:activity category="Define"> <os:activityAction context="selection"> <os:execute method="get" action="http://www.wordnik.com/words/{selection}" ></os:execute> </os:activityAction> </os:activity> </os:openServiceDescription> That’s it. To get it, go here. Enjoy!

• Collision Detection for a 2D RPG

  - by PHMitrious

  First of all, I have done some research on this topic before asking, and I'm asking this question as a mean to get some opinions on this topic, so I don't make a decision only on my own, but taking into account other people's experience as well. I'm starting a 2D online RPG project. I am using SFML for graphics and input and I'm creating a basic game structure and all for the game, creating modules for each part of the game. Well, let me get to the point I just wanted to give you guys some context. I want to decide on how I'm going to work with collision detection. Well I'm kinda going to work on maps with a tile map divided in layers (as usual) and add an extra 2 layers - not exactly in the map - for objects. So I'll have collisions between objects and agents (players - npcs - monsters - spells etc) and agents and tiles. The seconds one can be easily solved the first one need a little bit of work. I considered both creating a basic collision test engine using polygons and a quadtree to diminish tests since I'm going to be working with big maps with lots of objects - creating both a physical and graphical world representation. And I also considered using a physics engine like Box2D for collision tests. I think the first approach would take more work on my part but the second one would have the overhead of using a whole physics engine for just collision detection and no physics. What do you guys think ?

• Is using multiple canvas objects a good practice?

  - by user1818924

  We're developing a jump and run game with HTML5 and JavaScript and have to build an own game framework for this. Here we have some difficulties and would like to ask you for some advice: We have a "Stage" object, which represents the root of our game and is a global div-wrapper. The stage can contain multiple "Scenes", which are also div-elements. We would implement a Scene for the playing task, for pause, etc. and switch between them. Each scene can therefore contain multiple "Layers", representing a canvas. These Layer contain "ObjectEntities", which represent images or other shapes like rectangles, etc. Each Objectentity has its own temporaryCanvas, to be able to draw images for one entity, whereas another contains a rectangle. We set an activeScene in our Stage, so when the game is played, just the active scene is drawn. Calling activeScene.draw(), calls all sublayers to draw, which draw their entities (calling drawImage(entity.canvas)). But is this some kind of good practice? Having multiple canvas to draw? Each game loop every layer-context is cleared and drawn again. E.g. we just have a still Background-Layer, … wouldn't it be more useful to draw this once and not to clear it every time and redraw it? Or should we use a global canvas for example in the Stage and just use this canvas to draw? But we thought this would be to expensive...

• Access Violation when trying to bind Vertex Object Array

  - by Paul

  I've just started digging into OpenGL and I've run into a problem trying to set a VOA. It's giving me a run-time error of : An unhandled exception of type 'System.AccessViolationException' At // Create and bind a VAO GLuint vao; glGenVertexArrays(1, &vao); glBindVertexArray(vao); I have searched the internet high and low for a solution and I haven't found one. The rest of my function looks like this: int main(array<System::String ^> ^args) { // Initialise GLFW if( !glfwInit() ) { fprintf( stderr, "Failed to initialize GLFW\n" ); return -1; } glfwOpenWindowHint(GLFW_FSAA_SAMPLES, 0); // 4x antialiasing glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3); // We want OpenGL 3.3 glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 3); glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); //We don't want the old OpenGL // Open a window and create its OpenGL context if( !glfwOpenWindow( 800, 600, 0,0,0,0, 32,0, GLFW_WINDOW ) ) { fprintf( stderr, "Failed to open GLFW window\n" ); glfwTerminate(); return -1; } // Initialize GLEW if (glewInit() != GLEW_OK) { fprintf(stderr, "Failed to initialize GLEW\n"); return -1; } glfwSetWindowTitle( "Game Engine" ); // Create and bind a VAO GLuint vao; glGenVertexArrays(1, &vao); glBindVertexArray(vao); glfwEnable( GLFW_STICKY_KEYS );

• Library Organization in .NET

  - by Greg Ros

  I've written a .NET bitwise operations library as part of my projects (stuff ranging from get MSB set to some more complicated bitwise transformations) and I mean to release it as free software. I'm a bit confused about a design aspect of the library, though. Many of the methods/transformations in the library come with different endianness. A simple example is a getBitAt method that regards index 0 as the least significant bit, or the most significant bit, depending on the version used. In practice, I've found that using separate functions for different endianness results in much more comprehensible and reusable code than assuming all operations are little-endian or something. I'm really stumped regarding how best to package the library. Should I have methods that have LE and BE versions take an enum parameter in their signature, e.g. Endianness.Little, Endianness.Big? Should I have different static classes with identically named methods? such as MSB.GetBit and LSB.GetBit On a much wider note, is there a standard I could use in cases like this? Some guide? Is my design issue trivial? I have a perfectionist bent, and I sometimes get stuck on tricky design issues like this... Note: I've sort of realized I'm using endianness somewhat colloquially to refer to the order/place value of digital component parts (be they bits, bytes, or words) in a larger whole, in any setting. I'm not talking about machine-level endianness or serial transmission endianness. Just about place-value semantics in general. So there isn't a context of targeting different machines/transmission techniques or something.

• What is the difference between apt-get and dpkg?

  - by William F. Hammond

  Both apt-get and dpkg can be used to install and remove packages. When to use which? Context: I'm in stuck in package limbo between 10.04.4 LTS and 12.04.1 LTS after an attempted upgrade via the package manager. For example, to fix things I wanted to remove "skype" so that things it depends on could be freed up. But "aptitude" (my normal package management tool) refused to remove it. The advice at http://administratosphere.wordpress.com/2011/11/02/rescuing-an-interrupted-ubuntu-upgrade/ seems helpful but not adequate to resolve my package conflicts. Also there's a strange thing where the grub menu seems not to be properly interpreted, but eventually I get the splash screen with "/ is not ready yet or not present. Continue to wait; or press S to skip or M to recover manually." Manual recovery puts me in a single user shell where I can easily remount / as rw and bring up the network. If I become myself, the command line seems quite robust, but, there seems to be no way to get X11 going.

• Trying to make ZeroRadiant work on Lubuntu 11.10

  - by maniat1k

  I'm looking to use ZeroRadiant to work on ubuntu, it's to create maps on urban terror, I know that works on windows and mac. I found this HOWTO but could not make it work. I've got stock on this when I do. ~/ZeroRadiant-src$ scons target=radiant,q3map2 config=release at the end shows me this: collect2: ld returned 1 exit status scons: *** [build/release/radiant/radiant.bin] Error 1 scons: building terminated because of errors. there's a note on the how to that says: If you get other errors, you may try asking for help in the GtkRadiant IRC channel, which is listed on the main ZeroRadiant page. the page does not there and I could find that IRC channel. EDIT thanks to @jokerdino in the chat sow me this If you have the proprietary NVIDIA driver installed and you get the following error when executing the build target above: /usr/bin/ld: cannot find -lGL collect2: ld returned 1 exit status scons: *** [build/release/radiant/radiant.bin] Error 1 scons: building terminated because of errors. then you should install one of the nvidia-glx-dev* packages as mentioned above in Step A, then try to execute the main build target to compile GtkRadiant again. I don't have nvidia; I do have ATI AMD Radeon HD 6320, and looks like it works. GL_VERSION: 4.1.11251 Compatibility Profile Context GL_VENDOR: ATI Technologies Inc. GL_RENDERER: AMD Radeon HD 6320 Graphics I'm think I do have video issues but.. how do I detect this? how can I continue?

• Add Events to Windows Live Calendar in IE 8

  - by Asian Angel

  Do you have event dates that you need to make note of while browsing in Internet Explorer? Adding those events to your Live Calendar is easy to do with the Add Events to Windows Live Calendar accelerator. Adding Events to your Live Calendar To add the accelerator click on Add to Internet Explorer and then confirm the installation when the secondary window appears. For our example we chose the “estimated” availability date of Microsoft Office 2010 to the public. At the bottom of the pre-order page we found the date we were looking for. To add an event highlight the desired text (will become event description) and select the Add an Event to Windows Live Calendar listing in the context menu. A new tab will be opened where you can add any relevant details or make final tweaks to the description before saving the event. There is our new calendar event ready to send out a notification e-mail for the Office 2010 release. The Add Events to Windows Live Calendar accelerator speeds up the process of adding events to your calendar by getting you directly to the event form.

• Linqpad and StreamInsight

  Slightly before the announcement of StreamInsight being available for Linqpad I downloaded it from here.  I had seen Roman Schindlauer demonstrate it at Teched and it looked a really good tool to do some StreamInsight dev.   You will need .Net 4.0 and StreamInsight installed. Here’s what you need to do after downloading and installing Linqpad. Add a new connection   The next thing we need to do is install and enable the StreamInsight driver.  Choose to view more drivers.   Choose StreamInsight     Select the driver after install     I have chosen the Default Context.     And after all that I can finally get to writing my query.  This is a very simple query where I turn a collection (IEnumerable) into a PointStream.  After doing that I create 30 minute windows over the stream before outputting the count of events in each of those windows to the result window.     I have played with Linqpad only a little but I think it is going to be a really good tool to get ideas developed and quickly.  I have also enabled Autcompletion (paid £25) and I recommend it.

• Inheritance vs composition in this example

  - by Gerenuk

  I'm wondering about the differences between inheritance and composition examined with concrete code relevant arguments. In particular my example was Inheritance: class Do: def do(self): self.doA() self.doB() def doA(self): pass def doB(self): pass class MyDo(Do): def doA(self): print("A") def doB(self): print("B") x=MyDo() vs Composition: class Do: def __init__(self, a, b): self.a=a self.b=b def do(self): self.a.do() self.b.do() x=Do(DoA(), DoB()) (Note for composition I'm missing code so it's not actually shorter) Can you name particular advantages of one or the other? I'm think of: composition is useful if you plan to reuse DoA() in another context inheritance seems easier; no additional references/variables/initialization method doA can access internal variable (be it a good or bad thing :) ) inheritance groups logic A and B together; even though you could equally introduce a grouped delegate object inheritance provides a preset class for the users; with composition you'd have to encapsule the initialization in a factory so that the user does have to assemble the logic and the skeleton ... Basically I'd like to examine the implications of inheritance vs composition. I heard often composition is prefered, but I'd like to understand that by example. Of course I can always start with one and refactor later to the other.

• What is Mark Shuttleworth's "Easter eggs" blog a reference to? [closed]

  - by fluteflute

  I saw this blog post today, and I was wondering if there's some meaning within the Ubuntu community that I've missed? (I know what an easter egg is in a computer context.) One of our ducks has started dropping eggs in random locations in the garden. I don’t know which duck, but I assume it’s one of the new females we took in from the SPCA, who hasn’t figured out “nesting” yet. I do love ‘em but they’re not African Grey’s in the IQ department. Anyhow, I think I finally understand why people hide eggs in the garden at Easter. Because ducks used to do it for them! I suppose, for millennia, this has been the season to go hunting for eggs. Now we just substitute chocolate ones instead. For the moment, I’ve kept them in a cool shady spot while I keep an eye out for an actual nest. If a polecat doesn’t find them first, I may be able to slip them onto the nest in time for them to get hatched along with some cousins.

• OpenGL ES Loading

  - by kuroutadori

  I want to know what is the norm of loading rendering code. Take a button. When the application is loaded, a texture is loaded which has the image of the button on it. When the button is tapped, it then adds a loader into a queue, which is loaded on render thread. It then loads up an array buffer with vertexes and tex coords when render is called. It then adds to a render tree. Then it renders. the render function looks like this void render() { update(); mBaseRenderer->render(); } update() is when the queue is checked to see if anything needs loading. mBaseRenderer->render() is the render tree. What I am asking then is, should I even have the update() there at all and instead have everything preloaded before it renders? If I can have it loaded when need, for instance when there is tap, then how can it be done (My current code causes an dequeueing buffer error (Unknown error: -75) which I assume is to do with OpenGL ES and the context)?

There are UX mobile, social media, and methodology takeaways there for us in Debra's blog. Fujitsu Raku-Raku Smartphone Demo  I encourage you to read Debra's blog. In it, she makes reference to a tailored social media experience for those digital seniors (???????) as they'd be called in Japan (UK and Ireland uses the term silver surfers). You can find that online experience here. Online Community site for Fujitsu Raku-Raku Smartphone Digital Seniors (English translation via Google Translate) It's an important reminder that UX is global sure, but also that worldwide accessibility and digital inclusion are priorities too for UX. It's vital that we understand such aspects of technology adoption and how the requirements of different categories of technology users can be met. Oracle is committed to providing the best possible user experience for enterprise users of all ages and abilities. That means talking with all sorts of people worldwide and understanding how and why they want to use our technology and what their context of use is. You can read more about Oracle's accessibility program on our corporate website. Proud to say I prompted a few questions in Japan all the way from Ireland. So, UX is not only global but you can drive UX research globally too without ever leaving home. Brilliant job, Debra. Here's to more such joint research creativity and UX collaborations worldwide between us. Wondering where we might go next? And what a fun way to do things too!

• Grouping a comma separated value on common data [closed]

  - by Ankit

  I have a table with col1 id int, col2 as varchar (comma separated values) and column 3 for assigning group to them. Table looks like col1 col2 group .............................. 1 2,3,4 2 5,6 3 1,2,5 4 7,8 5 11,3 6 22,8 This is only the sample of real data, now I have to assign a group no to them in such a way that output looks like col1 col2 group .............................. 1 2,3,4 1 2 5,6 1 3 1,2,5 1 4 7,8 2 5 11,3 1 6 22,8 2 The logic for assigning group no is that every similar comma separated value of string in col2 have to be same group no as every where in col2 where '2' is there it has to be same group no but the complication is that 2,3,4 are together so they all three int value if found in any where in col2 will be assigned same group. The major part is 2,3,4 and 1,2,5 both in col2 have 2 so all int 1,2,3,4,5 have to assign same group no. Tried store procedure with match against on col2 but not getting desired result Most imp (I can't use normalization, because I can't afford to make new table from my original table which have millions of records), even normalization is not helpful in my context. This question is also on stackoverflow with bounty on this link Achieved so far:- I have set the group column auto increment and then wrote this procedure:- BEGIN declare cil1_new,col2_new,group_new int; declare done tinyint default 0; declare group_new varchar(100); declare cur1 cursor for select col1,col2,`group` from company ; DECLARE CONTINUE HANDLER FOR NOT FOUND SET done=1; open cur1; REPEAT fetch cur1 into col1_new,col2_new,group_new; update company set group=group_new where match(col2) against(concat("'",col2_new,"'")); until done end repeat; close cur1; select * from company; END This procedure is working, no syntax mistake but the problem is that I am not achieving the desired result exactly.

• Entity Framework and distributed Systems

  - by Dirk Beckmann

  I need some help or maybe only a hint for the right direction. I've got a system that is sperated into two applications. An existing VB.NET desktop client using Entity Framework 5 with code first approach and a asp.net Web Api client in C# that will be refactored right yet. It should be possible to deliver OData. The system and the datamodel is still involving and so migrations will happen in undefined intervalls. So I'm now struggling how to manage my database access on the web api system. So my favourd approch would be us Entity Framework on both systems but I'm running into trouble while creating new migrations. Two solutions I've thought about: Shared Data Access dll The first idea was to separate the data access layer to a seperate project an reference from each of the systems. The context would be the same as long as the dll is up to date in each system. This way both soulutions would be able to make a migration. The main problem ist that it is much more complicate to update a web api system than it is with the client Click Once Update Solution and not every migration is important for the web api. This would couse more update trouble and out of sync libraries Database First on Web Api The second idea was just to use the database first approch an on web api side. But it seems that all annotations will be lost by each model update. Other solutions with stored procedures have been discarded because of missing OData support and maintainability. Does anyone run into same conflicts or has any advices how such a problem can be solved!

• OUM is Flexible and Scalable

  - by user535886

  Flexible and Scalable Traditionally, projects have been focused on satisfying the contents of a requirements document or rigorously conforming to an existing set of work products. Often, especially where iterative and incremental techniques have not been employed, these requirements may be inaccurate, the previous deliverables may be flawed, or the business needs may have changed since the start of the project. Fitness for business purpose, derived from the Dynamic Systems Development Method (DSDM) framework, refers to the focus of delivering necessary functionality within a required timebox. The solution can be more rigorously engineered later, if such an approach is acceptable. Our collective experience shows that applying fit-for-purpose criteria, rather than tight adherence to requirements specifications, results in an information system that more closely meets the needs of the business. In OUM, this principle is extended to refer to the execution of the method processes themselves. Project managers and practitioners are encouraged to scale OUM to be fit-for-purpose for a given situation. It is rarely appropriate to execute every activity within OUM. OUM provides guidance for determining the core set of activities to be executed, the level of detail targeted in those activities and their associated tasks, and the frequency and type of end user deliverables. The project workplan should be developed from this core. The plan should then be scaled up, rather than tailored down, to the level of discipline appropriate to the identified risks and requirements. Even at the task level, models and work products should be completed only to the level of detail required for them to be fit-for-purpose within the current iteration or, at the project level, to suit the business needs of the enterprise and to meet the contractual obligations that govern the project. OUM provides well defined templates for many of its tasks. Use of these templates is optional as determined by the context of the project. Work products can easily be a model in a repository, a prototype, a checklist, a set of application code, or, in situations where a high degree of agility is warranted, simply the tacit knowledge contained in the brain of an analyst or practitioner. For further reading on agility, see Balancing Agility and Discipline: A guide fro the Perplexed.

• Should a stack trace be in the error message presented to the user?

  - by Vilx-

  I've got a bit of an argument at my workplace and I'm trying to figure out who is right, and what is the right thing to do. Context: an intranet web application that our customers use for accounting and other ERP stuff. I'm of the opinion that an error message presented to the user (when things crash) should include as much information as possible, including the stack trace. Of course, it has to start with a nice "An Error has occurred, please submit the below information to the developers" in large, friendly letters. My reasoning is that a screenshot of the crashed application will often be the only easily available source of information. Sure, you can try to get a hold of the client's systems administrator(s), attempt to explain where your log files are, etc, but that will probably be slow and painful (talking to the client representatives mostly is). Also, having an immediate and full information is extremely useful in development, where you don't have to go hunting through the log files to find what you need on every exception. (But that could be solved with a configuration switch.) Unfortunately there has been some kind of "Security audit" (no idea how they did that without the sources... but whatever), and they complained about the full exception messages citing them as a security threat. Naturally, the clients (at least one that I know of) has taken this at face value and now demands that the messages be cleaned. I fail to see how a potential attacker could use a stack trace to figure anything out he couldn't have figured out before. Are there any examples, any documented proof of anyone ever doing that? I think that we should fight this foolish idea, but perhaps I'm the fool here, so... Who's right?

• Change a Foreign Action's Display Text

  - by Geertjan

  I want the display text on an Action on a Node to show something about the underlying object. But the Action is registered somewhere in the layer (i.e., in the registry), i.e., I have no control over it. How do I change the display text in this scenario? Here's how. Below I look in the Actions/Events folder, iterate through all the Actions registered there, look for an Action with display text starting with "Edit", change it to display something from the underlying object, wrap a new Action around that Action, build up a new list of Actions, and return those (together with all the other Actions in that folder) from "getActions" on my Node: @Override public Action[] getActions(boolean context) { List<Action> newEventActions = new ArrayList<Action>(); List<? extends Action> eventActions = Utilities.actionsForPath("Actions/Events"); for (final Action action : eventActions) { String value = action.getValue(Action.NAME).toString(); if (value.startsWith("Edit")) { Action editAction = new AbstractAction("Edit " + getLookup().lookup(Event.class).getPlace()) { @Override public void actionPerformed(ActionEvent e) { action.actionPerformed(e); } }; newEventActions.add(editAction); } else { newEventActions.add(action); } } return newEventActions.toArray(new Action[eventActions.size()]); } If someone knows of a better way, please let me know.
