  • How can I find the shortest path between two subgraphs of a larger graph?

    - by Pops
    I'm working with a weighted, undirected multigraph (loops not permitted; most node connections have multiplicity 1; a few node connections have multiplicity 2). I need to find the shortest path between two subgraphs of this graph that do not overlap with each other. There are no other restrictions on which nodes should be used as start/end points. Edges can be selectively removed from the graph at certain times (as explained in my previous question) so it's possible that for two given subgraphs, there might not be any way to connect them. I'm pretty sure I've heard of an algorithm for this before, but I can't remember what it's called, and my Google searches for strings like "shortest path between subgraphs" haven't helped. Can someone suggest a more efficient way to do this than comparing shortest paths between all nodes in one subgraph with all nodes in the other subgraph? Or at least tell me the name of the algorithm so I can look it up myself? For example, if I have the graph below, the nodes circled in red might be one subgraph and the nodes circled in blue might be another. The edges would all have positive integer weights, although they're not shown in the image. I'd want to find whatever path has the shortest total cost as long as it starts at a red node and ends at a blue node. I believe this means the specific node positions and edge weights cannot be ignored. (This is just an example graph I grabbed off Wikimedia and drew on, not my actual problem.)

  • Can Kind People Finish First?

    - by Oracle Accelerate for Midsize Companies
    by Jim Lein, Oracle Midsize Programs In an earlier post, I expressed my undying love for KIND Snacks' products. This month's Oracle Profit magazine features an interview with KIND Healthy Snacks Founder and CEO Daniel Lubetzky entitled "Better Business". Lubetzky expresses his vision for making KIND a "not for profit only" company.  All great companies start with a good idea. In this case, that one great idea was to offer a healthy snack with ingredients you can "see and pronounce". That's one of things I really like about this company--that coupled with the fact that their snacks taste great. They compete in an over crowded playing field but I've found that it's rare to find an energy snack that both tastes good and is good for you.  A couple of interesting facts I learned from reading this article: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} 9 out of 10 consumers who try a KIND bar will purchase a KIND product again and recommend it to others KIND has the highest Net Promoter Score among the top 10 brands in the nutritional bar category (I confess I've never heard about this rating before but now that I have it's pretty cool) KIND's coporate mantra, "Do the Kind Thing" both encourages people to do random acts of kindness and provides easy mechanisms for doing so. Not coincidentally, I think, KIND is indeed a story about how nice guys can finish first. KIND has doubled in size every year for the last ten  years and now employees over 300 people, with sales exceeding $120M annually. Growth Applies Pressures One thing I know for certain from interacting our with fast growing customers over the last fifteen years is that growth applies myriad pressures across the organization--resources, processes, technology systems, and leadership agility. And it's easy to forget that Oracle was once an entrepreneurial startup and experienced all those same pressures that other growing companies are experiencing today. When asked by Profit Editor in Chief Aaron Lazenby, " What sort of pressure does KIND"s growth and success place on operations?", Lubetzky responded, "We have a demand planning process right now that is manual to a significant extent, and it just takes so much management time. It takes us days and sometimes weeks to produce information that is critical to our business—and by the time we get the results, we need revised data. Our sales leadership could go out selling, but instead they’re talking to our team about forecasts." Hitching Your Wagon to Oracle Lubetzky and his team selected Oracle for what I believe is our company's greatest strength: hitch your wagon to Oracle and you can trust that we will be there for the long run with the solutions you need and financial staying power. In Lubetzky's words, "The KIND philosophy requires you to have a long-term view of things; taking shortcuts may be the fastest way to get things done, but in the long term that can come back and bite you. Oracle is the type of company—and has the kind of platform—that is here for the long term. It’s not going to go away tomorrow. And Oracle is going to invest all the necessary resources into staying ahead of the game and improving." o next time you're in the supermarket or an REI (my favorite store in the world) or any of the other 80,000 locations that carry KIND, give one a try. Maybe some day you'll want to become a KIND Brand Ambassador.   Looking for more news and information about Oracle Solutions for Midsize Companies?

  • Expressing the UI for Enterprise Applications with JavaFX 2.0 FXML - Part Two

    - by Janice J. Heiss
    A new article by Oracle’s Java Champion Jim Weaver, titled “Expressing the UI for Enterprise Applications with JavaFX 2.0 FXML -- Part Two,” now up on otn/java, shows developers how to leverage the power of the FX Markup Language to define the UI for enterprise applications. Weaver, the author of Pro JavaFX Platform, extends the SearchDemoFXML example used in Part One to include more concepts and techniques for creating an enterprise application using FXML. Weaver concludes the article by summarizing its content, “FXML provides the ability to radically change the UI without modifying the controller. This task can be accomplished by loading different FXML documents, leveraging JavaFX cascading style sheets, and creating localized resource bundles. Named parameters can be used with these features to provide relevant information to an application at startup.” Check out the article here.

  • XNA C# How to draw fonts in different color

    - by XNA newbie
    I'm doing a simple chat system with XNA C#. It is a chatbox that contains 5 lines of chat typed by the users. Something like a MMORPG chatting system. [User1name] says: Hi [User2name] says: Hello [User1name] says: What are you doing? [User2name] says: I'm fine [System] The time is now 1:03AM. When the user pressed 'ENTER', the text he entered will be added inside an ArrayList chatList.Add(s); For displaying the text he entered, I used for (int i = 0; i < chatList.Count(); i++) { spriteBatch.DrawString(font, chatList[i], new Vector2(40, arr1[i]), Color.Yellow); } *arr1[i] contains 5 y-axis points to print my 5 line of chats in the chatbox Question1: What if I have another type of message which will be added into ChatList (something like a system message). I need the System Message to be printed out in red color. And if the user keeps on chatting, the chat box will be updated according: (MAX 5 LINES) The newest chat will be shown below, and the oldest one will be deleted if they reached the max 5 lines. [User2name] says: Hello [User1name] says: What are you doing? [User2name] says: I'm fine [System] The time is now 1:03AM. [User1name] says: Ok, great to hear that! I'm having trouble to print each line color according to their msg type. For normal msg, it should be yellow. For system msg, it should be red. Question2: And for the next problem, I need the chat texts to be white color, while the names of the user is yellow (like warcraft3 chat system). How do I do that? I have a hard time thinking of a solution for these to work. Advise needed.

  • Setup a Autoreply Only Account

    - by dabrain
    For some very good reason you might would like to setup a 'autoreply' only account, without storing the incoming mail into a mailbox. If not already done, create an account via Delegated Admin Gui or commadmin Commandline Tool. Example: /opt/sun/comms/da/bin/commadmin user create -D admin -d vmdomain.tld -w enigma -F Mike -l    mparis -L Paris -W tester -E [email protected] -S mail -H mars.vmdomain.tld Setup mailDeliveryOption to autoreply mode only, so no email will be stored in the user mailbox, skip this step if you want incoming emails stored in the mailbox. ldapmodify -D "cn=Directory Manager" -w enigma -f /tmp/modfile [/tmp/modfile] dn: uid=mparis,ou=People,o=vmdomain.tld,o=red changetype: modify replace: mailDeliveryOption mailDeliveryOption: autoreply Setup mailSieveRuleSource with the autoreply text and 'do-not-reply' From address. The "Thank you ..." part becomes the subject. The next string in quotes is the body part of the message. The ":hours 0" denotes that we want a reply sent for every message. Finally,  the \n is used because of the wanted newlines in the body. ldapmodify -D "cn=Directory Manager" -w enigma -f /tmp/addfile [/tmp/addfile] dn: uid=mparis,ou=People,o=vmdomain.tld,o=red changetype: modify add: mailSieveRuleSource mailSieveRuleSource: require "vacation"; vacation :hours 0 :reply :from "do-not-reply   @domain.com" :subject "Thank you for contacting webpost" "Your Mail is being review   ed.\nTo access contact information please visit : http://www.domain.com \nPlease do    not reply to this e-mail as it is an automated response on your mail being accessed   .\n\nPublic Respose Unit.\n"

  • Drawing text from update method in XNA

    - by Sigh-AniDe
    I am having a problem drawing the "Game Over!" text once the user is on the last tile. This is what I have: The Update and drawText methods are in a class named turtle: public void Update(float scalingFactor, int[,] map, SpriteBatch batch, SpriteFont font) { if (isMovable(mapX, mapY - 1, map)) { position.Y = position.Y - (int)scalingFactor; angle = 0.0f; Program.form.direction = ""; if (mapX == 17 && mapY == 1)// This is the last tile(Tested) { Program.form.BackColor = System.Drawing.Color.Red; drawText(batch, font); } } } public void drawText(SpriteBatch spritebatch, SpriteFont spriteFont) { textPosition.X = 200; // a vector2 textPosition.Y = 200; spritebatch.Begin(SpriteSortMode.BackToFront, BlendState.AlphaBlend); spritebatch.DrawString(spriteFont, "Game Over!!!", textPosition, Color.Red); spritebatch.End(); } This update is in the Game1 class: protected override void Update(GameTime gameTime) { // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); turtle.Update(scalingFactor, map, spriteBatch, font); base.Update(gameTime); } I have also added the font content to LoadContent: font = Content.Load<SpriteFont>("fontType"); What am I doing wrong? Why does the text not want to show on game completion? If I call the turtle.draw() in the main Draw method. The "Game Over" text stays on screen from the beggining. What am I missing? Thanks

  • XNA, how to draw two cubes standing in line parallelly?

    - by user3535716
    I just got a problem with drawing two 3D cubes standing in line. In my code, I made a cube class, and in the game1 class, I built two cubes, A on the right side, B on the left side. I also setup an FPS camera in the 3D world. The problem is if I draw cube B first(Blue), and move the camera to the left side to cube B, A(Red) is still standing in front of B, which is apparently wrong. I guess some pics can make much sense. Then, I move the camera to the other side, the situation is like: This is wrong.... From this view, the red cube, A should be behind the blue one, B.... Could somebody give me help please? This is the draw in the Cube class Matrix center = Matrix.CreateTranslation( new Vector3(-0.5f, -0.5f, -0.5f)); Matrix scale = Matrix.CreateScale(0.5f); Matrix translate = Matrix.CreateTranslation(location); effect.World = center * scale * translate; effect.View = camera.View; effect.Projection = camera.Projection; foreach (EffectPass pass in effect.CurrentTechnique.Passes) { pass.Apply(); device.SetVertexBuffer(cubeBuffer); RasterizerState rs = new RasterizerState(); rs.CullMode = CullMode.None; rs.FillMode = FillMode.Solid; device.RasterizerState = rs; device.DrawPrimitives( PrimitiveType.TriangleList, 0, cubeBuffer.VertexCount / 3); } This is the Draw method in game1 A.Draw(camera, effect); B.Draw(camera, effect); **

  • Does TDD's "Obvious Implementation" mean code first, test after?

    - by natasky
    My friend and I are relatively new TDD and have a dispute about the "Obvious Implementation" technique (from "TDD By Example" by Kent Beck). My friend says it means that if the implementation is obvious, you should go ahead and write it - before any test for that new behavior. And indeed the book says: How do you implement simple operations? Just implement them. Also: Sometimes you are sure you know how to implement an operation. Go ahead. I think what the author means is you should test first, and then "just implement" it - as opposed to the "Fake It ('Till You Make It)" and other techniques, which require smaller steps in the implementation stage. Also after these quotes the author talks about getting "red bars" (failing tests) when doing "Obvious Implementation" - how can you get a red bar without a test?. Yet I couldn't find any quote from the book saying "obvious" still means test first. What do you think? Should we test first or after when the implementation is "obvious" (according to TDD, of course)? Do you know a book or blog post saying just that?

  • Showing content from pages at different URL's (masking), possibly with .htaccess

    - by zigojacko
    If I have URL's like:- domain.com/category/widgets/filter/blue domain.com/category/widgets/filter/red And it is pretty difficult to reconstruct them to something like:- domain.com/category/blue-widgets domain.com/category/red-widgets Is there any way at all that I can use URL rewrites or anything else with .htaccess or on the server to display the URL's as the domain.com/category/blue-widgets on the domain.com/category/widgets/filter/blue page? I've looked into masking URL's but got nowhere and this has been something bugging me for almost 6 months now. Is there any way to achieve what I want to do? FYI: This is a Magento website and the above process, I am wanting to implement for potentially hundreds of URL's. Edit To respond to @kkugelmann's answer:- I couldn't get your proposed RewriteRule to make a difference at all in the .htaccess file so I started testing a few things in this .htaccess tester:- The proposed RewriteRule didn't work in this tester:- However, the following did:- But adding any of these RewriteRule's into the website's .htaccess file did not rewrite the URL at all... Edit2 By the way, if I add [R=301,L] to the end of the URL rewrite rule, it does actually then rewrite the rule, but of course 301 redirects it as well which is unwanted behaviour. Edit3 I found another question with the same issue... And an accepted answer that solved the problem which seemed to be something to do with using mod_proxy and the [P] tag on the rule (if I try this, the page 404's).

  • Announcing Spacewalk Support for Oracle Linux Basic and Premier Customers

    - by Michele Casey
    Over the years, customers migrating to Oracle Linux have asked for options to provide a transitional solution for their existing system management tools (such as Red Hat Satellite Server) while evaluating and planning migrations to Oracle's Enterprise Manager, which is offered at no additional charge with Oracle Linux Support Subscriptions.  Based on this request, we are pleased to announce support for the open-source community project, Spacewalk, which is the basis for both Red Hat Satellite Server and SUSE Manager.  Effective today, customers with Oracle Linux Basic and Premier Support subscriptions have access to a fully supported Spacewalk build which can be setup to easily manage Oracle Linux systems.   Spacewalk support for Oracle Linux requires Oracle Linux 6, x86_64 for the server and provides support for Oracle Linux 5 and Oracle Linux 6 (x86, x86_64) clients.  This solution requires Oracle Database 11g Release 2 as the  supported database repository for Spacewalk with Oracle Linux.  Within the next several weeks, a limited use license for the Oracle Database will be included with this offer.  Until this is complete, customers may use an existing Oracle database license or they may begin by downloading a 30-day trial license from eDelivery.  Customers with Oracle Linux Basic and Premier subscriptions will automatically have access to the channel hosting the supported build.  Please review the release notes for further instructions. Oracle Enterprise Manager is still the recommended enterprise solution for managing Oracle Linux systems and we want to provide the easiest transition path for our customers.  We are excited to offer this solution to our Oracle Linux customers while they plan and implement their migration to Oracle Enterprise Manager.

  • Assigning valid moves on board game

    - by Kunal4536
    I am making a board game in unity 4.3 2d similar to checkers. I have added an empty object to all the points where player can move and added a box collider to each empty object.I attached a click to move script to each player token. Now I want to assign valid moves. e.g. as shown in picture... Players can only move on vertex of each square.Player can only move to adjacent vertex.Thus it can only move from red spot to yellow and cannot move to blue spot.There is another condition which is : if there is the token of another player at the yellow spot then the player cannot move to that spot. Instead it will have to go from red to green spot. How can I find the valid moves of the player by scripting. I have another problem with click to move. When I click all the objects move to that position.But I only want to move a single token. So what can i add to script to select a specific object and then click to move the specific object.Here is my script for click to move. var obj:Transform; private var hitPoint : Vector3; private var move: boolean = false; private var startTime:float; var speed = 1; function Update () { if(Input.GetKeyDown(KeyCode.Mouse0)) { var hit : RaycastHit; // no point storing this really var ray = Camera.main.ScreenPointToRay (Input.mousePosition); if (Physics.Raycast (ray, hit, 10000)) { hitPoint = hit.point; move = true; startTime = Time.time; } } if(move) { obj.position = Vector3.Lerp(obj.position, hitPoint, Time.deltaTime * speed); if(obj.position == hitPoint) { move = false; } } }`

  • Is There A Security Risk With Users That Are Also Groups?

    - by Rob P.
    I know a little about users and groups; in the past I might have had a group like 'DBAS' or 'ADMINS' and I'd add individual users to each group... But I was surprised to learn I could add users to other users - as if they were groups. For example if my /etc/group contained the following: user1:x:12501: user2:x:12502:user1 admin:x:123:user2,jim,bob Since user2 is a member of the admin group, and user1 is a member of user2 - is user1 effectively an admin? If the admin group is in the sudoers file, can user1 use it as well? I've tried to simulate this and I haven't been able to do so as user1...but I'm not sure it's impossible. EDIT: SORRY - updated error in question.

  • Game: Age of Empires sound good but video "out of range"

    - by Ezekiel
    I'm new to the Ubuntu realm. Currently i'm using Linux Mint 12 with Wine 1.4 and PLAYONLINUX as game loading/playing programs. Video card is MSI GeForce FX5200 (NVIDIA) and is 3d enabled. I can play "Call of Duty 5 demo just fine. My real love is the Age of Empires series games. I loaded the WINE version of AOE 1 demo. No sound and no picture. Black screen with "Out of Range" window in red. I loaded my CD version of AOE 1 through PLAYONLINUX. I get the sound just fine but again the black screen with "Out of Range" window in red. I have used all the monitor settings in both the "settings" and in winecfg. None of the eight monitor options worked in any combination. I have checked all the questions and blogs on this error and tried all I found and no one seems to come up with a real fix. I guess I need to know exactly what the "Out of Range" means. Any help? Anywhere? Thanks

  • What to expect when creating a style guide?

    - by ted.strauss
    My organization would like to create a full fledged style guide that will be applicable to internal & external web sites, print advertising, trade show design, and overall branding. This article lays out the scope we're aiming for, and has links to many great examples style guide PDFs. The goal is to create a style guide comparable to one of these. I'd like to set realistic expectations within my organization for creating this document. So I have a few of questions pertaining to this: We don't have design staff. Should we be looking for a design firm or freelancer to come in for a 2-6 month contract, or do we need a longer commitment? If we do go with a firm or freelancer, would the pay-scale be comparable to typical design work, or is a style guide a higher order of work? How long should it take a pro to create a style guide? To make estimates more concrete, let's say web only, including all custom graphics. Any red flags to watch out for? (Compare: a new coder who fails to use css properly would be a red flag.)

  • Validate that a Checkbox is checked using javascript

    - by H(at)Ni
    I was facing a challenge yesterday that I was creating a Visual webpart and I wanted to validate the a submit button is only visible if the user checked a "I agree to terms" checkbox. Something was weired that I tested my code on a normal asp.net website and it worked perfectly while it had a different behaviour inside the webpart which is whenever I check the checkbox, the button is enabled but it will not fire the asp.net validators in client side. It posts back the page and then the validators appear after that. So, I tried to change my type of thinking and I reached a different solution is that to call a javascript function whenever the button is clicked and then check if the checkbox is clicked or not. To illustrate more, here are an example to what I'm saying: 1. Button in aspx page: <asp:Button OnClientClick="CheckForCondition();"  ValidationGroup="CompaniesSection" ID="btnCompaniesSubmit"                         runat="server" Text="Submit" /> 2. CheckForCondition() function: <script language="javascript" type="text/javascript">                         function CheckForCondition() {                             if ($jq('#<%= ChkCompanyCheck.ClientID %>:checked').val() == undefined) {                                 $jq('#lblCheckBox').show();                                 return false;                             }                             else {                                 $jq('#lblCheckBox').hide();                                 return true;                             }                         }                      </script> 3. lblCheckBox is simply a label that shows a red asterisk beside the checkbox to indicate that it's a required field. <label id="lblCheckBox" style="color:Red;display:none">*</label>

  • Triangulating a partially triangulated mesh (2D)

    - by teodron
    Referring to the above exhibits, this is the scenario I am working with: starting with a planar graph (in my case, a 2D mesh) with a given triangulation, based on a certain criterion, the graph nodes are labeled as RED and BLACK. (A) a subgraph containing all the RED nodes (with edges between only the directly connected neighbours) is formed (note: although this figure shows a tree forming, it may well happen that the subgraph contain loops) (B) Problem: I need to quickly build a triangulation around the subgraph (e.g. as shown in figure C), but under the constraint that I have to keep the already present edges in the final result. Question: Is there a fast way of achieving this given a partially triangulated mesh? Ideally, the complexity should be in the O(n) class. Some side-remarks: it would be nice for the triangulation algorithm to take into account a certain vertex priority when adding edges (e.g. it should always try to build a "1-ring" structure around the most important nodes first - I can implement iteratively such a routine, but it's O(n^2) ). it would also be nice to reflect somehow the "hop distance" when adding edges: add edges first between the nodes that were "closer" to each other given the start topology. Nevertheless, disregarding the remarks, is there an already known scenario similar to this one where a triangulation is built upon a partially given set of triangles/edges?

  • Web Services and code lists

    - by 0x0me
    Our team heavily discuss the issues how to handle code list in a web service definition. The design goal is to describe a provider API to query a system using various values. Some of them are catalogs resp. code lists. A catalog or code list is a set of key value pairs. There are different systems (at least 3) maintaining possibly different code lists. Each system should implement the provider API, whereas each system might have different code list for the same business entity eg. think of colors. One system know [(1,'red'),(2,'green')] and another one knows [(1,'lightgreen'),(2,'darkgreen'),(3,'red')] etc. The access to the different provider API implementations will be encapsulated by a query service, but there is already one candidate which might use at least one provider API directly. The current options to design the API discussed are: use an abstract code list in the interface definition: the web service interface defines a well known set of code list which are expected to be used for querying and returning data. Each API provider implementation has to mapped the request and response values from those abstract codelist to the system specific one. let the query component handle the code list: the encapsulating query service knows the code list set of each provider API implementation and takes care of mapping the input and output to the system specific code lists of the queried system. do not use code lists in the query definition at all: Just query code lists by a plain string and let the provider API implementation figure out the right value. This might lead to a loose of information and possibly many false positives, due to the fact that the input string could not be canonical mapped to a code list value (eg. green - lightgreen or green - darkgreen or both) What are your experiences resp. solutions to such a problem? Could you give any recommendation?
