  • SpaceX’s Dragon Spacecraft Docks with the ISS [Video]

    - by Jason Fitzpatrick
    This weekend was the first time a commercial space craft successfully rendezvoused with the International Space Station. Check out this video to see the opening of the hatch. From the notes on NASA’s video release: Aboard the International Space Station, Expedition 31 Flight Engineer Don Pettit and Joe Acaba of NASA and European Space Agency Flight Engineer Andre Kuipers opened the hatch to SpaceX’s Dragon cargo craft and entered the vehicle May 26, one day after the world’s first commercial cargo spacecraft was berthed to the Earth-facing port of the Harmony module. Dragon will remain berthed to Harmony until May 31, enabling the crew to unload supplies for the station’s residents before it is re-grappled and released to return to Earth for a parachute-assisted splashdown in the Pacific Ocean off the coast of southern California.

BPM is as much about people as it is about technology. As people adopt new ways of engagement, new channels of communications and new devices to interact , the changes are reflected in BPM practices. As Social and Mobile have become an integral part of our personal and professional lives, we’ll see tighter integration of social and mobile with BPM, and more use cases emerging for smarter process management in 2013. And with products and services becoming less differentiated, organizations will strive to differentiate on Customer Experience. Concepts like Pace Layered Architecture and Dynamic Case Management will provide more flexibility and agility to IT groups and knowledge workers. Take a look at some of these capabilities we showcased (see video) at Oracle OpenWorld 2012. Some of these trends that will continue to gain momentum in 2013: Social networks and social media have provided a new way for businesses to engage with customers. A prospect is likely to reach out to their social network before making any purchase. Companies are increasingly engaging with customers in social networks to influence their purchasing decisions, as well as listening to customers via tools like sentiment analysis to see what customers think about a particular product or process. These insights are valuable as companies look to improve their processes. Inside organizations, workers are using social tools to engage with each other to design new products and processes. Social collaboration tools are being used to resolve issues where an employee needs consultation to reach a decision. Oracle BPM Suite includes social interaction as an integral part of its process design and work management to empower today’s business users. Ubiquitous smart mobile devices are trending as a tool of choice for many workers. Many companies are adopting the policy of “Bring Your Own Device,” and the device of choice is a tablet. Devices like smart phones and tablets not only provide mobility to workers and customers, but they also provide additional important information – the context. By integrating the mobile context (location, photos, and preferences) into your processes, organizations can make much more informed decisions, as well as offer more personalized service to customers. Using Oracle ADF Mobile, you can easily create user interfaces for mobile devices and also capture location data for process execution. Customer experience was at the forefront of trending topics in 2012. Organizations are trying to understand their customers better and offer them more personalized and differentiated services. Customer experience is paramount when companies design sales and support processes. Companies are looking to BPM to consistently and efficiently orchestrate customer facing processes across disparate systems, departments and channels of communication. Oracle BPM Suite provides just the right capabilities for organizations to design and deliver an excellent customer experience. Pace Layered Architecture strategy is gaining traction as a way to maximize agility and minimize disruption in organizations. It provides a framework to manage the evolution of your information system when different pieces of it are changing at different rates and need to be updated independent of one another. Oracle Fusion Middleware and Oracle BPM Suite are designed with this in mind. The database layer, integration layer, application layer, and process layer should not be required to change at the same time. Most of the business changes to policy or process can be done at the process layer without disrupting the whole infrastructure. By understanding the type of change needed at a particular level, organizations can become much more agile and efficient. Adaptive Case Management proposes more flexibility to manage processes or cases that do not follow a structured process flow. In such situations, the knowledge worker managing the case needs to evaluate what step should occur next because the sequence of steps can’t be predetermined. Another characteristic is that it requires much more collaboration than straight-through process. As simple processes become automated, and customers adopt more and more self-service, cases that reach the case workers are much more complex and need more investigation. Oracle BPM suite includes comprehensive adaptive case management capability to manage such unstructured and complex processes. Smart BPM or making your BPM intelligent has been the holy grail for BPM practitioners who imagined that one day BPM would become one with Business Intelligence, Business Activity Monitoring and Complex Event Processing, making it much more responsive and helpful in organizational decision making. In 2013, organizations will begin to deploy these intelligent BPM solutions. Oracle offers an integrated solution that brings together the powerful functionality of BI, BAM, event processing, and Real Time Decisions to help organizations create smart process based solutions. In order to help customers reach their BPM goals faster and remove risks associated with BPM initiatives, Oracle has introduced Oracle Process Accelerators, pre-built best practices applications built on Oracle BPM Suite that are fully production grade and ready to deploy. These are exiting times for BPM practitioners and there is so much to look forward to in 2013. We wish you a very happy and prosperous New Year 2013. Happy BPMing!

  • Emacs saying: <M-kp-7> is undefined when dictating quotes with Dragon naturally speaking 12

    - by Keks Dose
    I dictating my text via Dragon Naturally Speaking 12 into Emacs. Whenever I say (translation from German): 'open quotes', I expect something like " or » to appear on the screen, but I simply get a message <M-kp-2> is undefined . Same goes for 'close quotes', I get <M-kp-7> is undefined. Does anybody know how to define those virtual keyboard strokes? (global-set-key [M-kp-2] "»") does not work.

  • is it wasteful/bad design to use a vector/list where in most instances it will only have one element

  • Can you swap dpi buttons on the Astra Dragon War mouse with 4th and 5th buttons?

    - by Denny Nuyts
    I'm left-handed and I'm in need of a good computer mouse with at least five buttons. However, most computer mice on the market are sadly right-handed and very impracticable to use with the extra buttons on my pinkie side instead of on my thumb side. The Dragon War Astra has two buttons on both sides. Buttons 4 and 5 on the left side and the dpi-buttons on the right side. If I were just able to re-assign them so they swap positions I'd have a great left-handed mouse. Sadly, the program X-Mouse Button Control doesn't allow the user to re-assign dpi buttons. My question is whether there exist other methods to still get it to work for me (third party programs, perhaps?). Or should I get another gaming mouse?

  • Why won't vsftpd let me log in with a virtual user account?

    - by Ramon
    I would like to use vsftpd with virtual users and pam_pwdfile.so. I installed vsftpd and added two users (ramon and dragon) via htpasswd to my file /etc/vsftpd.passwd. The /etc/pam.d/vsftpd is configured to use this file. auth required pam_listfile.so item=user sense=deny file=/etc/ftpusers onerr=succeed auth required pam_pwdfile.so pwdfile /etc/vsftpd.passwd account required pam_permit.so @include common-account @include common-session The user "ramon" is also available in /etc/passwd. A login to the ftp with the user "ramon" works as expected. But a login using "dragon" does not :/ The result is always Login failed: 530 Login incorrect. Since it's possible that I made a mistake I tried the exact way documented in /usr/share/doc/vsftpd/examples/VIRTUAL_USERS/README. Still no luck. I can login with the user "ramon", but not with the user "dragon". Any ideas?

  • Unity: how to apply programmatical changes to the Terrain SplatPrototype?

    - by Shivan Dragon
    I have a script to which I add a Terrain object (I drag and drop the terrain in the public Terrain field). The Terrain is already setup in Unity to have 2 PaintTextures: 1 is a Square (set up with a tile size so that it forms a checkered pattern) and the 2nd one is a grass image: Also the Target Strength of the first PaintTexture is lowered so that the checkered pattern also reveals some of the grass underneath. Now I want, at run time, to change the Tile Size of the first PaintTexture, i.e. have more or less checkers depending on various run time conditions. I've looked through Unity's documentation and I've seen you have the Terrain.terrainData.SplatPrototype array which allows you to change this. Also there's a RefreshPrototypes() method on the terrainData object and a Flush() method on the Terrain object. So I made a script like this: public class AStarTerrain : MonoBehaviour { public int aStarCellColumns, aStarCellRows; public GameObject aStarCellHighlightPrefab; public GameObject aStarPathMarkerPrefab; public GameObject utilityRobotPrefab; public Terrain aStarTerrain; void Start () { //I've also tried NOT drag and dropping the Terrain on the public field //and instead just using the commented line below, but I get the same results //aStarTerrain = this.GetComponents<Terrain>()[0]; Debug.Log ("Got terrain "+aStarTerrain.name); SplatPrototype[] splatPrototypes = aStarTerrain.terrainData.splatPrototypes; Debug.Log("Terrain has "+splatPrototypes.Length+" splat prototypes"); SplatPrototype aStarCellSplat = splatPrototypes[0]; Debug.Log("Re-tyling splat prototype "+aStarCellSplat.texture.name); aStarCellSplat.tileSize = new Vector2(2000,2000); Debug.Log("Tyling is now "+aStarCellSplat.tileSize.x+"/"+aStarCellSplat.tileSize.y); aStarTerrain.terrainData.RefreshPrototypes(); aStarTerrain.Flush(); } //... Problem is, nothing gets changed, the checker map is not re-tiled. The console outputs correctly tell me that I've got the Terrain object with the right name, that it has the right number of splat prototypes and that I'm modifying the tileSize on the SplatPrototype object corresponding to the right texture. It also tells me the value has changed. But nothing gets updated in the actual graphical view. So please, what am I missing?

  • Blender mesh mirroring screws up normals when importing in Unity

    - by Shivan Dragon
    My issue is as follows: I've modeled a robot in Blender 2.6. It's a mech-like biped or if you prefer, it kindda looks like a chicken. Since it's symmetrical on the XZ plane, I've decided to mirror some of its parts instead of re-modeling them. Problem is, those mirrored meshes look fine in Blender (faces all show up properly and light falls on them as it should) but in Unity faces and lighting on those very same mirrored meshes is wrong. What also stumps me is the fact that even if I flip normals in Blender, I still get bad results in Unity for those meshes (though now I get different bad results than before). Here's the details: Here's a Blender screen shot of the robot. I've took 2 pictures and slightly rotated the camera around so the geometry in question can be clearly seen: Now, the selected cog-wheel-like piece is the mirrored mesh obtained from mirroring the other cog-wheel on the other (far) side of the robot torso. The back-face culling is turned of here, so it's actually showing the faces as dictated by their normals. As you can see it looks ok, faces are orientated correctly and light falls on it ok (as it does on the original cog-wheel from which it was mirrored). Now if I export this as fbx using the following settings: and then import it into Unity, it looks all screwy: It looks like the normals are in the wrong direction. This is already very strange, because, while in Blender, the original cog-wheel and its mirrored counter part both had normals facing one way, when importing this in Unity, the original cog-wheel still looks ok (like in Blender) but the mirrored one now has normals inverted. First thing I've tried is to go "ok, so I'll flip normals in Blender for the mirrored cog-wheel and then it'll display ok in Unity and that's that". So I went back to Blender, flipped the normals on that mesh, so now it looks bad in Blender: and then re-exported as fbx with the same settings as before, and re-imported into Unity. Sure enough the cog-wheel now looks ok in Unity, in the sense where the faces show up properly, but if you look closely you'll notice that light and shadows are now wrong: Now in Unity, even though the light comes from the back of the robot, the cog-wheel in question acts as if light was coming from some-where else, its faces which should be in shadow are lit up, and those that should be lit up are dark. Here's some things I've tried and which didn't do anything: in Blender I tried mirroring the mesh in 2 ways: first by using the scale to -1 trick, then by using the mirroring tool (select mesh, hit crtl-m, select mirror axis), both ways yield the exact same result in Unity I've tried playing around with the prefab import settings like "normals: import/calculate", "tangents: import/calculate" I've also tired not exporting as fbx manually from Blender, but just dropping the .blend file in the assets folder inside the Unity project So, my question is: is there a way to actually mirror a mesh in Blender and then have it imported in Unity so that it displays properly (as it does in Blender)? If yes, how? Thank you, and please excuse the TL;DR style.

Problem is, nothing gets changed, the checker map is not re-tiled. The console outputs correctly tell me that I've got the Terrain object with the right name, that it has the right number of splat prototypes and that I'm modifying the tileSize on the SplatPrototype object corresponding to the right texture. It also tells me the value has changed. But nothing gets updated in the actual graphical view. So please, what am I missing?

  • Should we always prefer OpenGL ES version 2 over version 1.x

    - by Shivan Dragon
    OpengGL ES version 2 goes a long way into changing the development paradigm that was established with OpenGL ES 1.x. You have shaders which you can chain together to apply varios effects/transforms to your elements, the projection and transformation matrices work completly different etc. I've seen a lot of online tutorials and blogs that simply say "ditch version 1.x, use version 2, that's the way to go". Even on Android's documentation it sais to "use version 2 as it may prove faster than 1.x". Now, I've also read a book on OpenGL ES (which was rather good, but I'm not gonna mention here because I don't want to give the impression that I'm trying to make hidden publicity). The guy there treated only OpenGL ES 1.x for 80% of the book, and then at the end only listed the differences in version 2 and said something like "if OpenGL ES 1 does what you need, there's no need to switch to version 2, as it's only gonna over complicate your code. Version 2 was changed a lot to facillitate newer, fancier stuff, but if you don't need it, version 1.x is fine". My question is then, is the last statement right? Should I always use Open GL ES version 1.x if I don't need version 2 only stuff? I'd sure like to do that, because I find coding in version 1.x A LOT simpler than version 2 but I'm afraid that my apps might get obsolete faster for using an older version.

  • Advantages of using pure JavaScript over JQuery

    - by Shivan Dragon
    What are the advantages of using Javascript-only versus using JQuery-only? I have limited experience with JavaScript and JQuery coding. I've added bits and snippets of each to HTML pages but I've mostly coded server-side stuff in other languages. I've noticed that while you can theoretically do the same things using either of the two approaches (and of course you can even mix 'em up in the same project) there seems to be a tendency to always start using JQuery from the very beginning no-matter what the project demands are. So I'm simply wondering, are there any punctual benefits to not use JQuery-only but instead to just use plain old JavaScript? I know this looks like a non-question because it can be said about it that "there's no definite answer" or "it can be debated for ever", but I'm actually hoping for punctual answers such as "You can do this in one approach and you cannot do it with the other". ==EDIT== As per scrwtp's comment, I'm not referring just to the DOM Handling part. My question is rather: JQuery is a library. For Javascript. What I find strange about this library as opposed to other libraries for other languages is that in JQyery's case it seems to be designed to be able to use it exclusively and not need to touch Javascript directly. This is as opposed to let's say Hibernate and SQL, where even though the library (or rather framework in this case, but I think the analogy still applies) takes the handle on A LOT of aspects, you still get to use SQL when using it, at least for some fringe cases. However in JQuery & Javascript case, you could do anything you do with Javascript using only JQuery (or at least that's how it seems to me).

  • Pathfinding Java library

    - by Shivan Dragon
    I'm an amateur game developer and somewhat amateur Java developer as well. I'm trying to find a way to have path finding for my game(s). I've first googled for some existing Java libraries that have various path-finding implementations, but I've failed to find any. It seems to me that the only way to get pathfinding code is to use it via a game engine (like Unity). But I'd just like to have a library that I can use and make the game loop and other stuff on my own. Failing to find such a library I've tried implementing some algorithms myself. I've managed to make a running AStar in Java, but for fancier stuff like DStar I find it hard to do it by hand. So then, my question is, are there any Java libraries that contain at least some basic pathfinding algorithms implementations?

  • 2D Side Scrolling game and "walk over ground" collision detection

    - by Fire-Dragon-DoL
    The question is not hard, I'm writing a game engine for 2D side scrolling games, however I'm thinking to my 2D side scrolling game and I always come up with the problem of "how should I do collision with the ground". I think I couldn't handle the collision with ground (ground for me is "where the player walk", so something heavily used) in a per-pixel way, and I can't even do it with simple shape comparison (because the ground can be tilted), so what's the correct way? I'know what tiles are and i've read about it, but how much should be big each tile to not appear like a stairs?Are there any other approach? I watched this game and is very nice how he walks on ground: http://www.youtube.com/watch?v=DmSAQwbbig8&feature=player_embedded If there are "platforms" in mid air, how should I handle them?I can walk over them but I can't pass "inside". Imagine a platform in mid air, it allows you to walk over it but limit you because you can't jump in the area she fits Sorry for my english, it's not my native language and this topic has a lot of keywords I don't know so I have to use workarounds Thanks for any answer Additional informations and suggestions: I'm doing a game course in this period and I asked them how to do this, they suggested me this approach (a QuadTree): -All map is divided into "big nodes" -Each bigger node has sub nodes, to find where the player is -You can find player's node with a ray on player position -When you find the node where the player is, you can do collision check through all pixels (which can be 100-200px nothing more) Here is an example, however i didn't show very well the bigger nodes because i'm not very good with photoshop :P How is this approach?

  • google-chrome video application association

    - by Ben Lee
    Is there any way to tell google-chrome to launch video files of particular types in an external application (or even just to bring up the download box as if the type was un-handled), instead of showing the video inside the browser? Searching online, it seems that chrome is supposed to use xdg-mime for file associations, but apparently is ignoring this for video. For example, when I do: xdg-mime query default video/mpeg It returns dragonplayer.desktop. But when I click on a mpeg video link, chrome displays it internally instead of launching Dragon Player (if I double click on a mpeg file in my file manager, on the other hand, it does open Dragon Player). So is there a way to tell chrome to respect this setting, or another way to coax chrome into opening the file externally? If it matters, I'm running the latest version of google-chrome stable (not chromium) at the time of writing, v. 18.0.1025.151, on kubuntu 11.10.

  • How do I ask google not to index certain parts of my page?

    - by Gavin Mannion
    I was searching for an old review on my site today and I noticed that Google is indexing the headline text in my latest article list on every page that it appears, obviously I guess. The problem is if I search for my Dragon's Lair review specifically to my site like this http://www.google.co.za/search?sugexp=chrome,mod=9&sourceid=chrome&ie=UTF-8&q=site%3Alazygamer.net+dragons+lair+review Then it returns a ton of pages that aren't appropriate as they aren't related to the review at all. The reason why I care is that I have a second Dragon's Lair review that was posted years ago and now I can't find it. Is there a way to hint to google that certain text isn't relevant to the actual content on the page? is it a terrible idea?

  • XNA Required information to represent 2D Sprite graphically

    - by Fire-Dragon-DoL
    I was thinking about dividing my game engine into 2 threads: render thread and update thread (I can't come up on how to divide update thread from physic thread at the moment). That said, I have to duplicate all Sprite informations, what do I really need to represents a 2D Sprite graphically? Here are my ideas (I'll mark with ? things that I'm not sure): Vector2 Position float Rotation ? Vector2 Pivot ? Rectangle TextureRectangle Texture2D Texture Vector2 ImageOrigin ? (is it tracked somewhere else?) If you have any suggestion about using different types for datas, it's appreciated Last part of the question: isn't this a lot of data to copy in a buffer?what should I really copy in the buffer?I'm following this tutorial: http://www.sgtconker.com/2009/11/article-multi-threading-your-xna/3/ Thanks UPDATE 1: Newer values at the moment: Vector2 Position float Rotation Vector2 Pivot Rectangle TextureRectangle Texture2D Texture Color Color byte Facing (can be left or right, I'll do it with an enum) I re-read the tutorial, what I was doing wrong is not that I need to pass all those values, I need to pass only changed values as messages. UPDATE 2: Vector2 Position float Rotation Vector2 Pivot Rectangle TextureRectangle Texture2D Texture Color Color bool Flip uint DrawOrder Vector2 Scale bool Visible ? Mhhh, should Visibile be included?

  • What is the start point in game development? Where to start?

    - by Dragon
    I understand, I'm not unique with such a question, there are a lot of questions like this one. But I hope you'll take a minute and maybe can give me a piece of advice. I have an idea to develop games, but I don't know where is the start point in game development. The learning curve isn't as straight as in learning of a programming language, but I want to give it a try. I have some experience with OOP and programming in general. I know (not too deep) C#, Java programming languages. I searched info on where to start, read a lot of blogs, forums and so on. Once I decided "stop wandering around, just start develop a game" and I started. At the moment I have a console version of very simple game (RPS - rock-paper-scissors) developed with C#. It has different modes: "player vs cpu" and "player vs player". Some time later I looked at the code and decided that it should be refactored or even redeveloped from the scratch. And I thought that time "GUI is what I need. I can add logic later." And now I'm here. I've already decided to make RPS with GUI, then make multiplayer and so on. I'm not thinking about 3D now, 2D is enough. It doesn't matter what language to use: C# or Java, I found frameworks for both - XNA (C#) and Slick (Java). Both are good for 2D game development. But I know nothing about sprites, how to bind objects on the screen and so on. You can say "you don't need it for such simple game like RPS", but RPS is the beginning, I have some ideas like "Tower Defense" game... you know, everybody has ideas, wishes.... and this knowledge is useful and in some way obligatory. So what is the start point to achieve my plans, ideas, wishes? Where to start? Is it possible to make game development learning curve a little bit straight? Or there're ways that amateur and game development beginners use for years? Thank you for you answers and advise in advance. P.S Sorry for that this post turned out an essay, but I tried to express my wish to start acting. Hope I managed to do it.

  • How to get GameElements (RigidBody) size in Unity

    - by Shivan Dragon
    I've made a prefab consisting of a Cube which I've first scaled to more resemble a brick. There's also a Rigidbody added to the cube (in the prefab). Now I want to use that prefab in a c# script to make a wall out of multiple bricks. My question is, how can I access the dimensions of my brick (width, height, the z dimension size) so that in my script I can make bricks which are placed one next to the other (and then one on top of the other)? I've looked at the documentation for GameObject and Rigidbody but I can't find anything helpful. Just for refference, my script so far is: public GameObject brick; void Start () { Instantiate(this.brick, new Vector3(0.01326297f, -30.07855f, 100f), Quaternion.identity); // int brickWidth = this.brick.????; }

  • Unity scaling instantiated GameObject at Start() doesn't "keep"

    - by Shivan Dragon
    I have a very simple scenario: A box-like Prefab which is imported from Blender automatically (I have the .blend file in the Assets folder). A script that has two public GameObject fields. In one I place the above prefab, and in the other I place a terrain object (which I've created in Unity's graphical view): public Collider terrain; public GameObject aStarCellHighlightPrefab; This script is attached to the camera. The idea is to have the Blender prefab instantiated, have the terrain set as its parent, and then scale said prefab instance up. I first did it like this, in the Start() method: void Start () { cursorPositionOnTerrain = new RaycastHit(); aStarCellHighlight = (GameObject)Instantiate(aStarCellHighlightPrefab, new Vector3(300,300,300), terrain.transform.rotation); aStarCellHighlight.name = "cellHighlight"; aStarCellHighlight.transform.parent = terrain.transform; aStarCellHighlight.transform.localScale = new Vector3(100,100,100); } and first thought it didn't work. However later I noticed that it did in fact work, in the sense where the scale was applied right at the start, but then right after the prefab instance came back to its initial scale. Putting the scale code in the Update() methods fixes it in the sense where now it stays scaled all the time: void Update () { aStarCellHighlight.transform.localScale = new Vector3(100,100,100); //... } However I've noticed that when I run this code, the object is first displayed without the scale being applied, and it takes about 5-10 seconds for the scale to happen. During this time everything works fine (like input and logging, etc). The scene is very simple, it's not like it has a lot of stuff to load or anything (there's a Ray cast from the camera on to the terrain, but that seems to happen without such delays). My (2 part) question is: Why doesn't it take the scale transform when I do it at the beginning in the Start() method. Why do I have to keep scaling it in the Update() method? Why does it take so long for the scale to "apply/show up".
