  • Oracle Warehouse Builder és Enterprise ETL

    - by Fekete Zoltán
    Friss és ropogós az adatlap!!! Fogyasszátok egészséggel: ODI Enterprise Edition: Warehouse Builder Enterprise ETL white paper. A jó hír: minden megvásárolt Oracle Database-hez ingyenese használható az Oracle Warehouse Builder alap (core) funkcionalitása. Mi is az az OWB core funkcionalitás, és mit használhatunk az opciókban? Az Enterprise ETL funkcionalitás az Oracle Data Integrator Enterprise Edition licensz részeként érheto el az OWB-hez. Azok a funkciók, amik csak az ODI EE licensszel érhetok el (a korábbi OWB Enterprise ETL opció is ennek a része) megtekinthetok itt is a szöveg alján. Ezek: - Transportable ETL modules, multiple configurations, and pluggable mappings - Operators for pluggable mapping, pluggable mapping input signature, pluggable mapping output signature - Design Environment Support for RAC - Metadata change propagation - Schedulable Mappings and Process Flows - Slowing Changing Dimensions (SCD) Type 2 and 3 - XML Files as a target - Target load ordering - Seeded spatial and streams transformations - Process Flow Activity templates - Process Flow variables support - Process Flow looping activities such as For Loop and While Loop - Process Flow Route and Notification activities - Metadata lineage and impact analysis - Metadata Extensibility - Deployment to Discoverer EUL - Deployment to Oracle BI Beans catalog Tehát ha komolyabb környezetben szeretném használni az OWB-t, több környezetbe deployálni, stb, akkor szükség van az ODI EE licenszre is.

  • KERPOOOOW!

    - by Matt Christian
    Recently I discovered the colorful world of comic books.  In the past I've read comics a few times but never really got into them.  When I wanted to start a collection I decided either video games or comics yet stayed away from comics because I am less familiar with them. In any case, I stopped by my local comic shop and picked up a few comics and a few trade paperbacks.  After reading them and understanding their basic flow I began to enjoy not only the stories but the art styles hiding behind those little white bubbles of text (well, they're USUALLY white).  My first stop at the comic store I ended up with: - Nemesis #1 (cover A) - Shuddertown #1 (cover A I think) - Daredevil: King of Hell's Kitchen Trade Paperback - Peter Parker: Spiderman - One Small Break Trade Paperback It took me about 3-4 days to read all of that including re-reading the single issues and glancing over the beginning of Daredevil again.  After a week of looking around online I knew a little more about the comics I wanted to pick up and the kind of art style I enjoyed.  While Peter Parker: Spiderman was ok, I really enjoyed the detailed, realistic look of Daredevil and Shuddertown. Now, a few years back I picked up the game The Darkness for PS3.  I knew it was based off a comic but never read the comic.  I decided I'd pick up a few issues of it and ended up with: - The Darkness #80 (cover A) - The Darkness #81 (cover A) - The Darkness #82 (cover A) - The Darkness #83 (cover A) - The Darkness Shadows and Flame #1  (one-shot; cover A) - The Darkness Origins: Volume 1 Trade Paperback (contains The Darkness #1-6) - New Age boards and bags for storing my comics The Darkness is relatively good though jumping from issue #6 to issue #80 I lost a bit on who the enemy in the current series is.  I think out of all of them, issue #83 was my favorite of them. I'm signed up at the local shop to continue getting Nemesis, The Darkness, and Shuddertown, and I'll probably pick up a few different ones this weekend...

  • 2D XNA C#: Texture2D Wrapping Issue

    - by Kieran
    Working in C#/XNA for a Windows game: I'm using Texture2D to draw sprites. All of my sprites are 16 x 32. The sprites move around the screen as you would expect, by changing the top X/Y position of them when they're being drawn by the spritebatch. Most of the time when I run the game, the sprites appear like this: and when moved, they move as I expect, as one element. Infrequently they appear like this: and when moved it's like there are two sprites with a gap in between them - it's hard to describe. It only seems to happen sometimes - is there something I'm missing? I'd really like to know why this is happening. [Edit:] Adding Draw code as requested: This is the main draw routine - it first draws the sprite to a RenderTarget then blows it up by a scale of 4: protected override void Draw(GameTime gameTime) { // Draw to render target GraphicsDevice.SetRenderTarget(renderTarget); GraphicsDevice.Clear(Color.CornflowerBlue); Texture2D imSprite = null; spriteBatch.Begin(SpriteSortMode.FrontToBack, null, SamplerState.PointWrap, null, null); ManSprite.Draw(spriteBatch); base.Draw(gameTime); spriteBatch.End(); // Draw render target to screen GraphicsDevice.SetRenderTarget(null); imageFrame = (Texture2D)renderTarget; GraphicsDevice.Clear(ClearOptions.Target | ClearOptions.DepthBuffer, Color.DarkSlateBlue, 1.0f, 0); spriteBatch.Begin(SpriteSortMode.FrontToBack, null, SamplerState.PointClamp, null, null); spriteBatch.Draw(imageFrame, new Vector2(0, 0), null, Color.White, 0, new Vector2(0, 0), IM_SCALE, SpriteEffects.None, 0); spriteBatch.End(); } This is the draw routine for the Sprite class: public virtual void Draw(SpriteBatch spriteBatch) { spriteBatch.Draw(Texture, new Vector2(PositionX, PositionY), null, Color.White, 0.0f, Vector2.Zero, Scale, SpriteEffects.None, 0.3f); }

  • Oracle SPARC SuperCluster and US DoD Security guidelines

    - by user12611852
    I've worked in the past to help our government customers understand how best to secure Solaris.  For my customer base that means complying with Security Technical Implementation Guides (STIGs) from the Defense Information Systems Agency (DISA).  I recently worked with a team to apply both the Solaris and Oracle 11gR2 database STIGs to a SPARC SuperCluster.  The results have been published in an Oracle White paper. The SPARC SuperCluster is a highly available, high performance platform that incorporates: SPARC T4-4 servers Exadata Storage Servers and software ZFS Storage appliance InfiniBand interconnect Flash Cache  Oracle Solaris 11 Oracle VM for SPARC Oracle Database 11gR2 It is targeted towards large, mission critical database, middleware and general purpose workloads.  Using the Oracle Solution Center we configured a SSC applied DoD security guidance and confirmed functionality and performance of the system.  The white paper reviews our findings and includes a number of security recommendations.  In addition, customers can contact me for the itemized spreadsheets with our detailed STIG reports. Some notes: There is no DISA STIG  documentation for Solaris 11.  Oracle is working to help DISA create one using their new process. As a result, our report follows the Solaris 10 STIG document and applies it to Solaris 11 where applicable. In my conversations over the years with DISA Field Security Office they have repeatedly told me, "The absence of a DISA written STIG should not prevent a product from being used.  Customer may apply vendor or industry security recommendations to receive accreditation." Thanks to the core team: Kevin Rohan, Gary Jensen and Rich Qualls as well as the staff of the Oracle Solution Center and Glenn Brunette for their help in creating the document.

  • "Accumulate" buffer results in XNA4?

    - by Utkarsh Sinha
    I'm trying to simulate a "heightmap" buffer in XNA4.0 but the results don't look correct. Here's what I'm hoping to achieve: http://www.youtube.com/watch?feature=player_detailpage&v=-Q6ISVaM5Ww#t=517s (8:38). From what I understand, here are the steps to reach there: Pass height buffer + current entity's heightmap Generate a stencil and update the height buffer Render sprite+stencil For now, I'm just trying to get the height buffer thing to work. So here's the problem. Inside the draw loop, I do the following: Create a new render target & set it Draw the heightmap with a sprite batch(no shaders) graphicsDevice.SetRenderTarget(null) Draw the rendertarget with SpriteBatch I expected to see all entities' heightmaps. But only the last entity's heightmap is visible. Any hints on what I'm doing wrong? Here's the code inside the draw loop: RenderTarget2D tempDepthStencil = new RenderTarget2D(graphicsDevice, graphicsDevice.Viewport.Width, graphicsDevice.Viewport.Height, false, graphicsDevice.DisplayMode.Format, DepthFormat.None); graphicsDevice.SetRenderTarget(tempDepthStencil); // Gather depth information SpriteBatch depthStencilSpriteBatch = new SpriteBatch(graphicsDevice); depthStencilSpriteBatch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend, SamplerState.LinearClamp, DepthStencilState.None, RasterizerState.CullCounterClockwise); depthStencilSpriteBatch.Draw(texHeightmap, pos, null, Color.White, 0, Vector2.Zero, 1, spriteEffects, 1); depthStencilSpriteBatch.End(); graphicsDevice.SetRenderTarget(null); SpriteBatch b1 = new SpriteBatch(graphicsDevice); b1.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend, null, null, null, null); b1.Draw((Texture2D)tempDepthStencil, Vector2.Zero, null, Color.White, 0, Vector2.Zero, 1, spriteEffects, 1); b1.End();

  • Passing javascript array of objects to WebService

    - by Yousef_Jadallah
    Hi folks. In the topic I will illustrate how to pass array of objects to WebService and how to deal with it in your WebService.   suppose we have this javascript code :  <script language="javascript" type="text/javascript"> var people = new Array(); function person(playerID, playerName, playerPPD) { this.PlayerID = playerID; this.PlayerName = playerName; this.PlayerPPD = parseFloat(playerPPD); } function saveSignup() { addSomeSampleInfo(); WebService.SaveSignups(people, SucceededCallback); } function SucceededCallback(result, eventArgs) { var RsltElem = document.getElementById("divStatusMessage"); RsltElem.innerHTML = result; } function OnError(error) { alert("Service Error: " + error.get_message()); } function addSomeSampleInfo() { people[people.length++] = new person(123, "Person 1 Name", 10); people[people.length++] = new person(234, "Person 2 Name", 20); people[people.length++] = new person(345, "Person 3 Name", 10.5); } </script> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } poeple :is the array that we want to send to the WebService. person :The function –constructor- that we are using to create object to our array. SucceededCallback : This is the callback function invoked if the Web service succeeded. OnError : this is the Error callback function so any errors that occur when the Web Service is called will trigger this function. saveSignup : This function used to call the WebSercie Method (SaveSignups), the first parameter that we pass to the WebService and the second is the name of the callback function.   Here is the body of the Page :<body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"> <Services> <asp:ServiceReference Path="WebService.asmx" /> </Services> </asp:ScriptManager> <input type="button" id="btn1" onclick="saveSignup()" value="Click" /> <div id="divStatusMessage"> </div> </form> </body> </html> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }     Then main thing is the ServiceReference and it’s path "WebService.asmx” , this is the Web Service that we are using in this example.     A web service will be used to receive the javascript array and handle it in our code :using System; using System.Web; using System.Web.Services; using System.Xml; using System.Web.Services.Protocols; using System.Web.Script.Services; using System.Data.SqlClient; using System.Collections.Generic; [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ScriptService] public class WebService : System.Web.Services.WebService { [WebMethod] public string SaveSignups(object [] values) { string strOutput=""; string PlayerID="", PlayerName="", PlayerPPD=""; foreach (object value in values) { Dictionary<string, object> dicValues = new Dictionary<string, object>(); dicValues = (Dictionary<string, object>)value; PlayerID = dicValues["PlayerID"].ToString(); PlayerName = dicValues["PlayerName"].ToString(); PlayerPPD = dicValues["PlayerPPD"].ToString(); strOutput += "PlayerID = " + PlayerID + ", PlayerName=" + PlayerName + ",PlayerPPD= " + PlayerPPD +"<br>"; } return strOutput; } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The first thing I implement System.Collections.Generic Namespace, we need it to use the Dictionary Class. you can find in this code that I pass the javascript objects to array of object called values, then we need to deal with every separate Object and implicit it to Dictionary<string, object> . The Dictionary Represents a collection of keys and values Dictionary<TKey, TValue> TKey : The type of the keys in the dictionary TValue : The type of the values in the dictionary. For more information about Dictionary check this link : http://msdn.microsoft.com/en-us/library/xfhwa508(VS.80).aspx   Now we can get the value for every element because we have mapping from a set of keys to a set of values, the keys of this example is :  PlayerID ,PlayerName,PlayerPPD, this created from the original object person.    Ultimately,this Web method return the values as string, but the main idea of this method to show you how to deal with array of object and convert it to  Dictionary<string, object> object , and get the values of this Dictionary.   Hope this helps,

  • SQLAuthority News – Microsoft Whitepaper – AlwaysOn Solution Guide: Offloading Read-Only Workloads to Secondary Replicas

    - by pinaldave
    SQL Server 2012 has many interesting features but the most talked feature is AlwaysOn. Performance tuning is always a hot topic. I see lots of need of the same and lots of business around it. However, many times when people talk about performance tuning they think of it as a either query tuning, performance tuning, or server tuning. All are valid points, but performance tuning expert usually understands the business workload and business logic before making suggestions. For example, if performance tuning expert analysis workload and realize that there are plenty of reports as well read only queries on the server they can for sure consider alternate options for the same. If read only data is not required real time or it can accept the data which is delayed a bit it makes sense to divide the workload. A secondary replica of the original data which can serve all the read only queries and report is a good idea in most of the cases where there is plenty of workload which is not dependent on the real time data. SQL Server 2012 has introduced the feature of AlwaysOn which can very well fit in this scenario and provide a solution in Read-Only Workloads. Microsoft has recently announced a white paper which is based on absolutely the same subject. I recommend it to read for every SQL Enthusiast who is are going to implement a solution to offload read-only workloads to secondary replicas.

  • Does Unity's "Transparent Bumped Specular" translate to "semi-shiny must be semi-transparent"?

    - by Shivan Dragon
    Unity's documentation for the "Transparent Bumped Specular" shader/material-type is simply a concatenation of each of the descriptions for its Transparent and Specular Shaders (and also Bumped, but that doesn't apply to the question): Transparent Properties This shader can make mesh geometry partially or fully transparent by reading the alpha channel of the main texture. In the alpha, 0 (black) is completely transparent while 255 (white) is completely opaque. If your main texture does not have an alpha channel, the object will appear completely opaque. (...) Specular Properties (...) Additionally, the alpha channel of the main texture acts as a Specular Map (sometimes called "gloss map"), defining which areas of the object are more reflective than others. Black areas of the alpha will be zero specular reflection, while white areas will be full specular reflection. To me this translates to: I have a mesh representig a car tire The texture need to be very shiny on the rims parts, and almost not shiny at all for the rubber parts Also since the rim is really complex, (with like cut-out decoretions and such), I will not build that into the mesh, but fake it with transparency in the texture I can't do all this using Unity's "Transparent Bumped Specular" shader, because the "rubber" part of the texture will become semi transparent due to me painting the alpha channel dark-grey (because I want it to also be less shiny). Is this correct? If not, how can I make this work?

  • HLSL - Creating Shadows in 2D

    - by richard
    The way that I create shadows is by the following technique: http://www.catalinzima.com/2010/07/my-technique-for-the-shader-based-dynamic-2d-shadows/ But I have questions to HLSL. The way that I currently do it is, I have a black and white image, where Black means 'object', and white means 'nothing'. I then distort the image like in the tutorial. I do this with a pixel shader, but instead of rendering to the screen, I render to a texture, back to my application. I then take this, and create the shadows, and then send it back to the graphics card to undo the distortion, after the shadow has been added - this comes back and I have a stencil of shadow. I can put this ontop of the original image and send them back to the graphics card, which then puts them on the screen. To me this is alot of back and forth. Is there a way i can avoid this? The problem that I am having is that I need to basically go through all positions in the texture 3 times, and use the new new texture every time instead of the orginal one. I tried to read up on Passes, but i don't think that i am heading in the right direction there. Help?

  • How to change circular icon to indicate chosen session in unity-greeter?

    - by Chan-Ho Suh
    In Precise (12.04), when I login to lightdm, using the unity-greeter, there's a white circle by my name. For the standard DEs like Unity or XFCE, the circle has a representative icon (Ubuntu symbol or little mouse resp.). I have a session for Awesome window manager which was added when I installed Awesome, but it just shows a blank white circle. I'd like to know how to add an icon to it, or at least some indicator, as unity-greeter doesn't show you what session is set until you click on the circle. I found another question about changing the session names. The answer for it said to change the names in the desktop files in /usr/share/xsessions. Unfortunately, while there is an icon field in those desktop files, they are all blank (Caveat: I no longer have Unity installed, so maybe the Unity one would not be blank. But the Xubuntu desktop file has it blank even though the icon shows in unity-greeter). Update: Here's the png I use as a badge for Awesome. It's not great, but looks reasonably nice: []

  • Painting with pixel shaders

    - by Gustavo Maciel
    I have an almost full understanding of how 2D Lighting works, saw this post and was tempted to try implementing this in HLSL. I planned to paint each of the layers with shaders, and then, combine them just drawing one on top of another, or just pass the 3 textures to the shader and getting a better way to combine them. Working almost as planned, but I got a little question in the matter. I'm drawing each layer this way: GraphicsDevice.SetRenderTarget(lighting); GraphicsDevice.Clear(Color.Transparent); //... Setup shader SpriteBatch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend, SamplerState.LinearClamp, DepthStencilState.None, RasterizerState.CullNone, lightingShader); SpriteBatch.Draw(texture, fullscreen, Color.White); SpriteBatch.End(); GraphicsDevice.SetRenderTarget(darkMask); GraphicsDevice.Clear(Color.Transparent); //... Setup shader SpriteBatch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend, SamplerState.LinearClamp, DepthStencilState.None, RasterizerState.CullNone, darkMaskShader); SpriteBatch.Draw(texture, fullscreen, Color.White); SpriteBatch.End(); Where lightingShader and darkMaskShader are shaders that, with parameters (view and proj matrices, light pos, color and range, etc) generate a texture meant to be that layer. It works fine, but I'm not sure if drawing a transparent quad on top of a transparent render target is the best way of doing it. Because I actually just need the position and params. Concluding: Can I paint a texture with shaders without having to clear it and then draw a transparent texture on top of it?

  • How do I draw a point sprite using OpenGL ES on Android?

    - by nbolton
    Edit: I'm using the GL enum, which is incorrect since it's not part of OpenGL ES (see my answer). I should have used GL10, GL11 or GL20 instead. Here's a few snippets of what I have so far... void create() { renderer = new ImmediateModeRenderer(); tiles = Gdx.graphics.newTexture( Gdx.files.getFileHandle("res/tiles2.png", FileType.Internal), TextureFilter.MipMap, TextureFilter.Linear, TextureWrap.ClampToEdge, TextureWrap.ClampToEdge); } void render() { Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT); Gdx.gl.glClearColor(0.6f, 0.7f, 0.9f, 1); } void renderSprite() { int handle = tiles.getTextureObjectHandle(); Gdx.gl.glBindTexture(GL.GL_TEXTURE_2D, handle); Gdx.gl.glEnable(GL.GL_POINT_SPRITE); Gdx.gl11.glTexEnvi(GL.GL_POINT_SPRITE, GL.GL_COORD_REPLACE, GL.GL_TRUE); renderer.begin(GL.GL_POINTS); renderer.vertex(pos.x, pos.y, pos.z); renderer.end(); } create() is called once when the program starts, and renderSprites() is called for each sprite (so, pos is unique to each sprite) where the sprites are arranged in a sort-of 3D cube. Unfortunately though, this just renders a few white dots... I suppose that the texture isn't being bound which is why I'm getting white dots. Also, when I draw my sprites on anything other than 0 z-axis, they do not appear -- I read that I need to crease my zfar and znear, but I have no idea how to do this using libgdx (perhaps it's because I'm using ortho projection? What do I use instead?). I know that the texture is usable, since I was able to render it using a SpriteBatch, but I guess I'm not using it properly with OpenGL.

  • How can I find unused/unapplied CSS rules in a stylesheet?

    - by liori
    Hello, I've got a huge CSS file and an HTML file. I'd like to find out which rules are not used while displaying a HTML file. Are there tools for this? The CSS file has evolved over few years and from what I know no one has ever removed anything from it--people just wrote new overriding rules again and again. EDIT: It was suggested to use Dust-Me Selectors or Chrome's Web Page Performance tool. But they both work on level of selectors, and not individual rules. I've got lots of cases where a rule inside a selector is always overridden--and this is what I mostly want to get rid of. For example: body { color: white; padding: 10em; } h1 { color: black; } p { color: black; } ... ul { color: black; } All the text in my HTML is inside some wrapper element, so it is never white. body's padding always works, so of course the whole body selector cannot be removed. And I'd like to get rid of such useless rules too. EDIT: And another case of useless rule: when it duplicates existing one without changing anything: a { margin-left: 5px; color: blue; } a:hover { margin-left: 5px; color: red; } I'd happily get rid of the second margin-left... again it seems to me that those tools does not find such things. Thank you,

  • Why doesn't my grub background show?

    - by luri
    I've tried to change resolution, colors and background image for my grub menu, but I get no background (well, just a black one, no image).... What am I doing wrong? This is my grub.cfg (omitting the OS's part): # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ]; then set have_grubenv=true load_env fi set default="${saved_entry}" if [ "${prev_saved_entry}" ]; then set saved_entry="${prev_saved_entry}" save_env saved_entry set prev_saved_entry= save_env prev_saved_entry set boot_once=true fi function savedefault { if [ -z "${boot_once}" ]; then saved_entry="${chosen}" save_env saved_entry fi } function recordfail { set recordfail=1 if [ -n "${have_grubenv}" ]; then if [ -z "${boot_once}" ]; then save_env recordfail; fi; fi } function load_video { insmod vbe insmod vga } insmod part_msdos insmod ext2 set root='(hd1,msdos5)' search --no-floppy --fs-uuid --set 42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 if loadfont /usr/share/grub/unicode.pf2 ; then set gfxmode=1280x1024x24 load_video insmod gfxterm fi terminal_output gfxterm insmod part_msdos insmod ext2 set root='(hd1,msdos5)' search --no-floppy --fs-uuid --set 42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 set locale_dir=($root)/boot/grub/locale set lang=es insmod gettext if [ "${recordfail}" = 1 ]; then set timeout=-1 else set timeout=10 fi ### END /etc/grub.d/00_header ### ### BEGIN /etc/grub.d/05_debian_theme ### insmod part_msdos insmod ext2 set root='(hd1,msdos5)' search --no-floppy --fs-uuid --set 42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 insmod jpeg if background_image /boot/grub/Serenity_Enchanted_by_sirpecangum.jpg ; then set color_normal=black/white set color_highlight=brown/light-gray else set menu_color_normal=white/black set menu_color_highlight=black/light-gray fi ### END /etc/grub.d/05_debian_theme ### The selected image has been copied to /boot/grub/Serenity_Enchanted_by_sirpecangum.jpg with no luck.

  • Floodfill algorithm for GO

    - by user1048606
    The floodfill algorithm is used in the bucket tool in MS paint and photoshop, but it can also be used for GO and minesweeper. http://en.wikipedia.org/wiki/Flood_fill In go you can capture groups of stones, this website portrays it with two stones. http://www.connectedglobe.com/mindy/cap6.html This is my floodfill method in Java, it is not capturing a group of stones and I have no idea why because to me it makes sense. public void floodfill(int turn, int col, int row){ for(int a = col; a<19; a++){ for(int b = row; b<19; b++){ if(turn == black){ if(stones[col][row] == white){ stones[col][row] = 0; floodfill(black, col-1, row); floodfill(black, col+1, row); floodfill(black, col, row-1); floodfill(black, col, row+1); } } } } } It searches up, down, left, right for all the stones on the board. If the stones are white it captures them by making them 0, which represents empty.

  • My first time in the gambling industry

    - by sfrj
    I am a Java enterprise developer with almost 3 years of professional experience. Soon i am going to have a face to face interview with a company in the gambling industry. I already did successfully a phone screening and now for the personal interview i suppose they will ask me about some kind of white board problem or system design task. I think i am in the right place to ask about this, and would appreciate a lot if someone would give me some tips or share something related to his own experience. The things i am more interested in regarding my interview are: What are the most common challenges for programmers, in this industry? Any idea or suggestion on a white board problem they may ask me? Could you point me to some links where i can find information on the topic or sample problems in this industry?. I personally find this question very interesting not just for me. Also i think, the given answers can help also others in a similar situation. Just what i want to say whit this last comment is: Please avoid, answers like: www.google.com and so on...

  • Need alternative to Accessibility's "Locate Pointer" to visually highlight the mouse.

    - by fred.bear
    Update: See end of quetion: A black-on-white cross-hair/I-bar mouse-pointer is soemtimes hard foe me to spot in amongst black-on-white text. I've tried "Accessibility / Mouse Accessibility / Locate Pointer" .. which will: Show pointer position when Control is presssed It works (to a point), but it does have a notable problem, which renders it inpractical. It has the uncanny side-effect of disallowing all Control key navigation while editing a file/dir name in Nautilus (F2).. Just touching the Control key drops it out of edit mode, which means I can't keyboard paste, move-L/R word etc... So, I'm looking for an alternative. I've tried Compiz's Water Effect, but I need something which is sharper, faster, and localized to the pointer. Compiz's Show Mouse (with fire) is no suitable. I'm really lookingf for an analog of "Accessibility / Locate Pointer": * ie. I hit Control (only).. and it blips a quick visual pulse. UPDATE: I've just realized why I can't find my mouse so often! ... It's because it is isn't there !!! ... Two apps I use a lot, Gedit and Konsole (KDE Terminal; it renders unicode better), ... dissolve the mouse-pointer to invisible after the first key is typed ... and Konsole does it after a few seconds of idle-time... like a video-player option: "hide the mouse".. Well I don't use the mouse much, and I thought it was juse my eyesight (which does rely a lot on Compiz's zoom)... I discovered it when I installed a "novelty" app, called Geyes from gnome-applets ("A goofy set of eyes for the GNOME panel. They follow your mouse.") ... It could follow the mouse better than me! :)

  • How to parse JSON data from web more faster [closed]

    - by Kaidul Islam Sazal
    I have json inventory inventory.json on the server like this: [ { "body" : "SUV", "color" : { "ext" : "White diamond pearl", "int" : "Taupe" }, "id" : "276181", "make" : "Acura", "miles" : 35949, "model" : "RDX", "pic" : [ { "full" : "http://images1.dealercp.com/90961/000JNBD/001_0292.jpg" } ], "power" : { "drive" : "Front wheel drive", "eng" : "2.3L DOHC PGM-FI 16-VALVE", "trans" : "Automatic" }, "price" : { "net" : 29488 }, "stock" : "6942", "trim" : "AWD 4dr Tech Pkg SUV", "vin" : "5J8TB2H53BA000334", "year" : 2011 }, { "body" : "Sedan", "color" : { "ext" : "Premium white pearl", "int" : "Taupe" }, "id" : "275622", "make" : "Acura", "miles" : 40923, "model" : "TSX", "pic" : [ { "full" : "http://images1.dealercp.com/90961/000JMC6/001_1765.jpg" } ], "power" : { "drive" : "Front wheel drive", "eng" : "2.4L L4 MPI DOHC 16V", "trans" : "Automatic" }, "price" : { "net" : 22288 }, "stock" : "6945", "trim" : "4dr Sdn I4 Auto Sedan", "vin" : "JH4CU2F66AC011933", "year" : 2010 } ] here are two index, There are almost 5000 index like this. I parsed this json like this: var url = "inventory/inventory.json"; $.getJSON(url, function(data){ $.each(data, function(index, item){ //straight-forward loop if(item.year == 2012) { $('#desc').append(item.make + ' ' + item.model + ' ' + '<br/>' + item.price.net + '<br/>' + item.pic[0].full); } }); }); This is working fine.But the problem is that, this searching and fetching process is little bit slow as there are 5000 indexes already and it's increasing day by day. It seems that, it is a straight-forward loop to parse the data and a normal brute-force method. Now I want to know if there any time efiicient way to parse more faster.Any faster method to parse instead of straight-forward loop ?

  • Alpha From PNGs Butchered

    - by ashes999
    I have a pretty vanilla Monogame game. I'm using PNG for all my sprites (made in Photoshop). I noticed that XNA is butchering the aliasing; no matter what I do, my graphics appear jaggedy. Below is a screenshot. The bottom half is what XNA shows me when I zoom in 2X using a Matrix on my GraphicsDevice (to make the effect more obvious). The top is when I pasted the same sprites from Photoshop and scaled them to 200%. Note that partially transparent pixels are turning whiteish. Is there a way to fix this? What am I doing wrong? Here's the relevant call to draw to the SpriteBatch: spriteBatch.Draw(this.texture, this.positionVector, null, Color.White, this.Angle, this.originVector, 1f, SpriteEffects.None, 0f); (this.positionVector can easily be Vector.Zero; Color.White as 100% alpha, I think; this.Angle can be a real angle (small > in the image) or zero (the orb itself).

  • Problem inserting pre-ordered values to quadtree

    - by Lucas Corrêa Feijó
    There's this string containing B, W and G (standing for black, white and gray). It defines the pre-ordered path of the quadtree I want to build. I wrote this method for filling the QuadTree class I also wrote but it doesn't work, it inserts correctly until it reaches a point in the algorithm it needs to "return". I use math quadrants convention order for insertion, such as northeast, northwest, southwest and southeast. A quadtree has all it's leafs black or white and all the other nodes gray The node used in the tree is called Node4T and has a char as data and 4 references to other nodes like itself, called, respectively NE, NW, SW, SE. public void insert(char val) { if(root==null) { root = new Node4T(val); } else { insert(root, val); } } public void insert(Node4T n, char c) { if(n.data=='G') // possible to insert { if(n.NE==null) { n.NE = new Node4T(c); return; } else { insert(n.NE,c); } if(n.NW==null) { n.NW = new Node4T(c); return; } else { insert(n.NW,c); } if(n.SW==null) { n.SW = new Node4T(c); return; } else { insert(n.SW,c); } if(n.SE==null) { n.SE = new Node4T(c); return; } else { insert(n.SE,c); } } else // impossible to insert { } } The input "GWGGWBWBGBWBWGWBWBWGGWBWBWGWBWBGBWBWGWWWB" is given a char at a time to the insert method and then the print method is called, pre-ordered, and the result is "GWGGWBWBWBWGWBWBW". How do I make it import the string correctly? Ignore the string reading process, suppose the method is called and it has to do it's job.

  • dual monitors and unity - ati radeon cards

    - by michiel
    I have a vaio laptop with an ATI Radeon video card and an external screen. I used to run dual monitors on Ubuntu 10.10 fine, but recently decided to upgrade to 11.10 via 11.04 I don't think it's the video card or the fglrx driver. It seems to be unity. When I start up, the laptop screen is normal and the external screen is all white, although I can move my mouse over it. However, the cursor becomes the big X that used to be cursor of the first versions of Xwindows. I can right click on it, and it brings up the context menu for the desktop. And then, all of a sudden, it shows my desktop background. I can continue to move my mouse over the external screen, and now the cursor is normal (little white arrow). But I can't do anything any longer (not even the context menu as before), and trying to drag a window to it (which always worked on 10.10) doesn't work. I actually really like unity. It gives me the most our of my desktop, and uses all space available, which is great. But how can I get my second screen back? I tried unity 2D, but the result is the same. Edit: I think I stumbled on this bug: https://bugs.launchpad.net/ubuntu/+source/nvidia-settings/+bug/882143

  • Grub does not show a Windows 8 option after dual boot

    - by skytreader
    So, I've successfully dual-booted my Windows 8 machine with Ubuntu 12.04 . However, I still don't have a convenient method of choosing what OS to load at boot time. After installing Ubuntu, my computer still loads Windows 8 directly. I then added grubx64.efi to the white list of my boot loader. But after that, my machine loads Ubuntu directly without even a shadow of GRUB showing up! I used boot-repair and I got this paste.ubuntu URL: paste.ubuntu.com/1326074. After running boot-repair (and re-white listing the grubx64.efi file), GRUB now shows up but without any Windows 8 option! Lastly, I ran sudo fdisk -l and it gave me this: WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sda: 750.2 GB, 750156374016 bytes 255 heads, 63 sectors/track, 91201 cylinders, total 1465149168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x6396389f Device Boot Start End Blocks Id System /dev/sda1 1 1465149167 732574583+ ee GPT Partition 1 does not start on physical sector boundary. I'm guessing my problem has something to do with the warning from fdisk above but I don't know what to do with it. How do I proceed now?
