• Use jQuery and ASP.NET to Build a News Ticker

  Many websites display a news ticker of one sort or another. A news ticker is a user interface element that displays a subset of a list of items, cycling through them one at a time after a set interval. For example, on Cisco's website there is a news ticker that shows the company's latest news items. Each news item is a one sentence link, such as "Desktop Virtualization Gathers Steam," or "Cisco Reports First Quarter Earnings." Clicking a headline whisks you to a page that shows the full story. Cisco's news ticker shows one headline at a time; every few seconds the currently displayed headline fades out and the next one appears. In total, Cisco has five different headlines - the ticker displays each of the five and then starts back from the beginning. This article is the first in a series that explores how to create your own news ticker widget using jQuery and ASP.NET. jQuery is a free, popular, open-source JavaScript library that simplifies many common client-side tasks, like event handling, DOM manipulation, and Ajax. This article kicks off the series and shows how to build a fairly simple news ticker whose contents can be specified statically in HTML markup or created dynamically from server-side code. Future installments will explore adding bells and whistles, such as: stopping the news ticker rotation when the mouse is hovered over it; adding controls to start, stop and pause the headlines; loading new headlines dynamically using Ajax; and packaging the JavaScript used by the ticker into a jQuery plugin.

• Troubleshooting VMware on Ubuntu

  Summary of different problems while using VMware products on Ubuntu. This article is going to be updated from time to time with new information about running VMware products more or less smoothly on Ubuntu. Following are links to existing articles: Running VMware Player on Linux (xubuntu Hardy Heron) Running VMware Server on Linux (version 1.0.6 on xubuntu) Using ext4 in VMware machine   VMware mouse grab/ungrab problem (Source: LinuxInsight) Upgrading GTK library in Ubuntu since Karmic Koala gives you a strange mouse behaviour. Even if you have "Grab when cursor enters window" option set, VMware won't grab your pointer when you move mouse into the VMware window. Also, if you use Ctrl-G to capture the pointer, VMware window will release it as soon as you move mouse around a little bit. Quite annoying behavior... Fortunately, there's a simple workaround that can fix things until VMware resolves incompatibilities with the new GTK library. VMware Workstation ships with many standard libraries including libgtk, so the only thing you need to do is to force it to use it's own versions. The simplest way to do that is to add the following line to the end of the /etc/vmware/bootstrap configuration file and restart the Workstation. export VMWARE_USE_SHIPPED_GTK="force" The interface will look slightly odd, because older version of GTK is being used, but at least it will work properly. Note: After upgrading a new Linux kernel, it is necessary to compile the VMware modules, this requires to temporarily comment the export line in /etc/vmware/bootstrap.

• I want to be a programmer, work in corporate environment, earn well, learn fast and eventually become a great programmer [on hold]

  - by Shin San

  I'll try to keep this simple: I'm 29, been dabbling with computers for the past 10 years, had entry level jobs in tech support for different apps, been fixing computers for a while and now want to specialize in something. I'm not 100% stranger to programming but haven't gone past if/then/else with anything. A bit of JavaScript, PHP, Python and currently checking out the "SELECT" statement in SQL :)) I'm curious about programming, I enjoy it and I'm thinking of making a living out of it. So, while I'm at it, why not earn a bit more than the average Joe? So, that's why I'm checking what the best solution, the best learning path and the most useful languages are considering: a) how easy/fast can you find a job by knowing it b) how much would I be able to earn c) how fast can I learn it By reading 10-20 articles online I've come up with an example, but I'm here for some expert advice. Example: * ratings from a) and b) point of view #1 sql ; #2 java ; #3 html (please don't start the markup language debate) ; #4 javascript From this ratings, I'd say a good way to go is learn html/css/(javascript or php) for the web part of apps, some SQL/MySQL/whateverSQL for holding data and loads of Java for the program itself. Please let me know if this is a good idea and if so, what should be the order for learning all of the above. Else, please let me know a better way and why it would be better. Many thanks for taking the time to read my question. Best wishes to you guys Edit: if I think Java + SQL + HTML&JavaScript is the way to go, does the order I'm learning them in matter? Or can I try to learn them all at once?

• Designing spawning system

  - by Vlad

  I played this game recently http://www.kongregate.com/games/JuicyBeast/knightmare-tower and I am amazed by the way how different monsters are beign spawned. I personally developed my own shooter game and I added time based but also count based spawing system. By count based I mean when there are 5 enemies on stage stop spawning. But this is one example. My question is how are these spawning mechanism built, is there some pattern or some theory how they are built? Are there some online materials/pages where I can improve my knowledge? To sumarize, let just say we have 6 types of monsters. I start the game and kill of monsters of type 1,2 and 3 all the time. Once I pass the first ceiling, like in the game above, monster type 4 appear. ANd so on. As I progress trough the game, the same system of 6 types of monsters stay, but they become more and more resilient and dangerous. So I must also improve to be able to destroy the same monsters but now stronger. My question is simple, are there some theories built or written for developing this type of inteligent systems? Note: This is a general question, not tied up with some game or how exactly should the game work. I am capable to program my own mechanisms but I think I need some help. Thanks.

• An Oracle's Interns Story by Samarth Varshney

  - by user769227

  I have written a short write-up about my experience at Oracle and am attaching some pics along:  I joined Oracle on 5th January 2011 as part of my internship program in BITS Pilani Goa Campus. In the short period of six months, I had the most beautiful and interesting time of my life. It was fun to work in Oracle, thanks to the whole team. I had an excellent manager, simple and sophisticated, who gave me the utmost enthusiasm to work. I gained a lot of knowledge during my internship, thanks to my colleagues. They were very helpful and motivated us (interns) in every possible way. In the initial stages of work, in which you know almost nothing, they helped me gain knowledge at a rapid speed. Thanks to the vast database of study material at the Oracle site, that I could start on with my project in a very short time.  For me, the time flew like anything and made the 6 months look like a few days. It was probably due to the team, that the work was so much fun. We had our deadlines but had full freedom as to how to work and when to work. I don't remember a single instance, in which I was working and not listening to songs. I mean it will always be a time to remember. I hope to join this company and make this time last forever.  Samarth

• Move a 2D square on y axis on android GLES2

  - by Dan

  I am trying to create a simple game for android, to start i am trying to make the square move down the y axis but the way i am doing it dosent move the square at all and i cant find any tutorials for GLES20 The on draw frame function in the render class updates the users position based on accleration dew to gravity, gets the transform matrix from the user class which is used to move the square down, then the program draws it. All that happens is that the square is drawn, no motion happens public void onDrawFrame(GL10 gl) { user.update(0.0, phy.AccelerationDewToGravity); GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT | GLES20.GL_DEPTH_BUFFER_BIT); // Re draws black background GLES20.glVertexAttribPointer(maPositionHandle, 3, GLES20.GL_FLOAT, false, 12, user.SquareVB);//triangleVB); GLES20.glEnableVertexAttribArray(maPositionHandle); GLES20.glUniformMatrix4fv(maPositionHandle, 1, false, user.getTransformMatrix(), 0); GLES20.glDrawArrays(GLES20.GL_TRIANGLE_STRIP, 0, 4); } The update function in the player class is public void update(double vh, double vv) { Vh += vh; // Increase horrzontal Velosity Vv += vv; // Increase vertical velosity //Matrix.translateM(mMMatrix, 0, (int)Vh, (int)Vv, 0); Matrix.translateM(mMMatrix, 0, mMMatrix, 0, (float)Vh, (float)Vv, 0); }

• New "delay" keyword for JavaScript

  - by Van Coding

  I had a great idea for a new javascript keyword "delay", but I don't know what I can do to bring it to the new specification. Also I want to know what you guys think about it and if it's even realistic. What does the delay keyword ? The delay keyword does nothing more than stop the execution of the current stack and immediately continues to the next "job" in the queue. But that's not all! Instead of discarding the stack, it adds it to the end of the queue. After all "jobs" before it are done, the stack continues to execute. What is it good for? delay could help make blocking code non-blocking while it still looks like synchronous code. A short example: setTimeout(function(){ console.log("two"); },0); console.log("one"); delay; //since there is currently another task in the queue, do this task first before continuing console.log("three"); //Outputs: one, two, three This simple keyword would allow us to create a synchronous-looking code wich is asynchronous behind the scenes. Using node.js modules, for example, would no longer be impossible to use in the browser without trickery. There would be so many possibilites with such a keyword! Is this pattern useful? What can I do to bring this into the new ECMAscript specification? Note: I asked this previously on Stack Overflow, where it was closed.

• Empty APN list on your Android phone? Restart the phone to fix it

  - by Gopinath

  Today I tried to connect to internet on my Google Galaxy Nexus running on 4.2.2 using Cellular Data connection and it failed. Tried reaching customer care representative to figure out why data connection is not working, but the robots (Interactive Voice Response systems) never allowed me to reach a human. After digging through the settings I found empty list of APN (Access Point Names) is the reason for not able to connect to internet. Not sure what caused APN list to vanish but I tried to create a new one that matches with the settings required for AT & T mobile. To my surprise I found that the newly created APN is also not shown in the APN list. Well there is something wrong with the phone – my APN’s are not shown as well as the newly created one is also not displayed. A simple Google search on this problem shown many forum discussions list and the solution to resolve the issue is to restart the phone. As soon as I restarted my phone the APN list is automatically populated and I’m able to connect to internet on my mobile.

• How exactly is an Abstract Syntax Tree created?

  - by Howcan

  I think I understand the goal of an AST, and I've build a couple of tree structures before, but never an AST. I'm mostly confused because the nodes are text and not number, so I can't think of a nice way to input a token/string as I'm parsing some code. For example, when I looked at diagrams of AST's, the variable and its value were leaf nodes to an equal sign. This makes perfect sense to me, but how would I go about implementing this? I guess I can do it case by case, so that when I stumble upon an "=" I use that as a node, and add the value parsed before the "=" as the leaf. It just seems wrong, because I'd probably have to make cases for tons and tons of things, depending on the syntax. And then I came upon another problem, how is the tree traversed? Do I go all the way down the height, and go back up a node when I hit the bottom, and do the same for it's neighbor? I've seen tons of diagrams on ASTs, but I couldn't find a fairly simple example of one in code, which would probably help.

• Using Coherence API to get POF bytes

  - by Bruno.Borges

  Someone raised the question on how to use the Coherence API to get the bytes of an object in POF (Portable Object Format) programatically. So I came up with this small code that shows the very cool API simple usage :-)   SimplePofContext spc = new SimplePofContext();    spc.registerUserType(0, User.class, new UserSerializer());    // consider UserSerializer as an implementation of PofSerializer            User u = new User();    u.setId(21);    u.setName("Some Name");    u.setEmail("[email protected]");            ByteArrayOutputStream baos = new ByteArrayOutputStream();    DataOutput dataOutput = new DataOutputStream(baos);    BufferOutput bufferOutput = new WrapperBufferOutput(dataOutput);    spc.serialize(bufferOutput, u);            byte[] byteArray = baos.toByteArray();    System.out.println(Arrays.toString(byteArray));  Easy, isn't?

• Inspiring the method of teaching. Example- C++ :)

  - by Ashwin

  A year ago I graduated with a degree in Computer Science and Engineering. Considering C++ as the first choice of programming language I have been in the process of learning C++ in many ways. At first - five years back - I had many conceptions, most of which were so abstract to me. It started when I knew almost everything about Structs in C and nothing about Classes in C++. I went through a great time experimenting them all and learning a lot. I had a hard time evaluating Procedural programming vs Object-Oriented Programming. Deciding when to choose Procedural or Object-Oriented Programming took a great deal of patience for me. I knew that I cannot underestimate any of these Programming styles... Though Procedural programming is often a better choice than simple sequential unstructured programming, when solving problems with procedural programming, we usually divide one problem into several steps in order regarded as functions. Then we call these functions one by one to get the result of the problem. When solving problems with Object Oriented Priciples we divide one problem into several classes and form the interaction between them. Evaluating these two at the beginning (as a learner) required a lot of inspiration and thoughts. Instructing to think step by step. Relative concepts to understand deeply. Intensive interests to contrast both solving in both POP and OOP. If you were ever a mentor: What ideas/methods would you teach to students in which it will Inspire them to learn a programming language (in general, computer sciences)?

• Should a project start with the client or the server?

  - by MadBurn

  Pretty simple question with a complex answer. Should a project start with the client or the server, and why? Where should a single programmer start a client/server project? What are the best practices and what are the reasons behind them? If you can't think of any, what reasons do you use to justify why you would choose to start one before the other? Personally, I'm asking this question because I'm finishing up specs for a project I will be doing for myself on the side for fun. But now that I'm finishing this phase, I'm wondering "ok, now where do I begin?" Since I've never done a project like this by myself, I'm not sure where I should start. In this project, my server will be doing all the heavy lifting and the client will just be sending updates, getting information from the server, and displaying it. But, I don't want that to sway the answer as I'm looking for more of an in depth and less specific answer that would apply to any project I begin in the future.

• UPDATE FOR BI PUBLISHER ENTERPRISE 10.1.3.4.2 NOVEMBER 2011

  - by Tim Dexter

  It's Friday, that means its patch release time. Why do we do this to ourselves, 'we'll release on Friday!' It might 11.59 on Friday but by golly we'll have released on Friday. I can remember a release of BIP years ago that for some reason we went for 12/31 as a release date ... were we mad? I seem to remember we made it but talk about ridiculous pressure! The latest 10g rollup is out in the wild and available from Oracle support. A bug fixing rollup but worth getting to and know that support will want you to get to it and re-test before going forward on an SR. One simple but very useful fix or enhancement:[Cause of the bug] @ ================== @ Customer reports that despite the clock being shown, end users are clicking @ on the View button repeatedly as the initial generation is taking some time.   @ If the button were to be grayed out then  this would prevent the users @ requesting the report more than  once.  Repeated requests are causing a @ system overload and as this is their Production  instance this is extremely @ important to the customer. @ . @ [The Fix] @ ========= @ Added the logic to disable the button after the user clicks on the "view" @ button and re-enable it when the report is loaded. I told a group of customers once that they have a headache and we have a non-steroidal anti-inflammatory drug, alright, I actually said 'aspirin'. This little gem of a fix helps relieve another little headache that our aspirin was causing. The patch number for all this BIP pain killing is 13399232, enjoy!

I have a simple project that I use to track my priorities throughout the day.  It uses some of Stephen Covey’s principles from The 7 Habits of Highly Effective People.  The idea is to write down all your priorities the night before and rank them.  This way when you get started tomorrow you will have your list of priorities.  Now it’s not that new things won’t appear tomorrow and reprioritize your list, but at least now you can track them.  My idea is to create a project that will allow you manage your list from your desktop, a web browser or your mobile device.  This way your list is never too far away.  I will layout the data model and the additional concepts as time progresses. My goal is to show the power of all of these tools combined and I thought the best way would be to build a project in sequence.  I have had this idea for quite some time so let’s get it completed with the outline below. Here is the outline of the series of post in the near future: Part 2 – Modeling the Business Objects Part 3 – Changing XAF Default Properties Part 4 – Advanced Settings within Liekhus EDMX/XAF Tool Part 5 – Custom Business Rules Part 6 – Unit Testing Our Implementation Part 7 – Behavior Driven Development (BDD) and SpecFlow Tests Part 8 – Using the Windows Application Part 9 – Using the Web Application Part 10 – Exposing OData from our Project Part 11 – Consuming OData with Excel PowerPivot Part 12 – Consuming OData with iOS Part 13 – Consuming OData with Android Part 14 – What’s Next I hope this helps outline what to expect.  I anticipate that I will have additional topics mixed in there but I plan on getting this outline completed within the next several weeks.  Thanks

• What is wrong with my game loop/mechanic?

  - by elias94xx

  I'm currently working on a 2d sidescrolling game prototype in HTML5 canvas. My implementations so far include a sprite, vector, loop and ticker class/object. Which can be viewed here: http://elias-schuett.de/apps/_experiments/2d_ssg/js/ So my game essentially works well on todays lowspec PC's and laptops. But it does not on an older win xp machine I own and on my Android 2.3 device. I tend to get ~10 FPS with these devices which results in a too high delta value, which than automaticly gets fixed to 1.0 which results in a slow loop. Now I know for a fact that there is a way to implement a super smooth 60 or 30 FPS loop on both devices. Best example would be: http://playbiolab.com/ I don't need all the chunk and debugging technology impact.js offers. I could even write a super simple game where you just control a damn square and it still wouldn't run on a equally fast 30 or 60 fps. Here is the Loop class/object I'm using. It requires a requestAnimationFrame unify function. Both devices I've tested my game on support requestAnimationFrame, so there is no interval fallback. var Loop = function(callback) { this.fps = null; this.delta = 1; this.lastTime = +new Date; this.callback = callback; this.request = null; }; Loop.prototype.start = function() { var _this = this; this.request = requestAnimationFrame(function(now) { _this.start(); _this.delta = (now - _this.lastTime); _this.fps = 1000/_this.delta; _this.delta = _this.delta / (1000/60) > 2 ? 1 : _this.delta / (1000/60); _this.lastTime = now; _this.callback(); }); }; Loop.prototype.stop = function() { cancelAnimationFrame(this.request); };

• Collision within a poly

  - by G1i1ch

  For an html5 engine I'm making, for speed I'm using a path poly. I'm having trouble trying to find ways to get collision with the walls of the poly. To make it simple I just have a vector for the object and an array of vectors for the poly. I'm using Cartesian vectors and they're 2d. Say poly = [[550,0],[169,523],[-444,323],[-444,-323],[169,-523]], it's just a pentagon I generated. The object that will collide is object, object.pos is it's position and object.vel is it's velocity. They're both 2d vectors too. I've had some success to get it to find a collision, but it's just black box code I ripped from a c++ example. It's very obscure inside and all it does though is return true/false and doesn't return what vertices are collided or collision point, I'd really like to be able to understand this and make my own so I can have more meaningful collision. I'll tackle that later though. Again the question is just how does one find a collision to walls of a poly given you know the poly vertices and the object's position + velocity? If more info is needed please let me know. And if all anyone can do is point me to the right direction that's great.

• How do I prevent my platformer's character from clipping on wall tiles?

  - by Jonathan Hobbs

  Currently, I have a platformer with tiles for terrain (graphics borrowed from Cave Story). The game is written from scratch using XNA, so I'm not using an existing engine or physics engine. The tile collisions are described pretty much exactly as described in this answer (with simple SAT for rectangles and circles), and everything works fine. Except when the player runs into a wall whilst falling/jumping. In that case, they'll catch on a tile and begin thinking they've hit a floor or ceiling that isn't actually there. The player is moving right and falling downwards. So after movement, collisions are checked - and first, it turns out the player character is colliding with the tile 3rd from the floor, and pushed upwards. Second, he's found to be colliding with the tile beside him, and pushed sideways - the end result being the player character thinks he's on the ground and isn't falling, and 'catches' on the tile for as long as he's running into it. I could solve this by defining the tiles from top to bottom instead, which makes him fall smoothly, but then the inverse case happens and he'll hit a ceiling that isn't there when jumping upwards against the wall. How should I approach resolving this, so that the player character can just fall along the wall as it should?

• More than one way to skin an Audit

  - by BuckWoody

  I get asked quite a bit about auditing in SQL Server. By "audit", people mean everything from tracking logins to finding out exactly who ran a particular SELECT statement. In the really early versions of SQL Server, we didn't have a great story for very granular audits, so lots of workarounds were suggested. As time progressed, more and more audit capabilities were added to the product, and in typical database platform fashion, as we added a feature we didn't often take the others away. So now, instead of not having an option to audit actions by users, you might face the opposite problem - too many ways to audit! You can read more about the options you have for tracking users here: http://msdn.microsoft.com/en-us/library/cc280526(v=SQL.100).aspx  In SQL Server 2008, we introduced SQL Server Audit, which uses Extended Events to really get a simple way to implement high-level or granular auditing. You can read more about that here: http://msdn.microsoft.com/en-us/library/dd392015.aspx  As with any feature, you should understand what your needs are first. Auditing isn't "free" in the performance sense, so you need to make sure you're only auditing what you need to. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• What would be a good filter to create 'magnetic deformers' from a depth map?

  - by sebf

  In my project, I am creating a system for deforming a highly detailed mesh (clothing) so that it 'fits' a convex mesh. To do this I use depth maps of the item and the 'hull' to determine at what point in world space the deviation occurs and the extent. Simply transforming all occluded vertices to the depths as defined by the 'hull' is fairly effective, and has good performance, but it suffers the problem of not preserving the features of the mesh and requires extensive culling to avoid false-positives. I would like instead to generate from the depth deviation map a set of simple 'deformers' which will 'push'* all vertices of the deformed mesh outwards (in world space). This way, all features of the mesh are preserved and there is no need to have complex heuristics to cull inappropriate vertices. I am not sure how to go about generating this deformer set however. I am imagining something like an algorithm that attempts to match a spherical surface to each patch of contiguous deviations within a certain range, but do not know where to start doing this. Can anyone suggest a suitable filter or algorithm for generating deformers? Or to put it another way 'compressing' a depth map? (*Push because its fitting to a convex 'bulgy' humanoid so transforms are likely to be 'spherical' from the POV of the surface.)

• Why are my videos playing speeded up with no audio, but work fine if I log in as a guest?

  - by Martins Kruze

  Since the start of this week I have been experiencing a glitch in the multimedia on my Samsung R518 laptop. I have 2 problems: Videos in every player are speeded up around 2 or 4 times (including youtube.com (both HTML5 and flash variants), any other video on the web and videos on my laptop played by Totem Media Player), exception is VLC player, but 2nd problem does concern even that. There is no sound - simple as that (with or without headphones plugged in). These all problems are now, and has not seen before, I upgraded to Ubuntu 10.10 after it was possible, and from start I didn't have anything from this - it just started in this week. I haven't even putted new software in. I have more or less solved the question (kind of) - I just logged in as a guest - and it all works, but when I make a new user - it does not. Please help me.
