• Highlighting effect to text and/or image similar to be synchronized with audio

  - by Irfan Mulic

  I am looking how to approach following problem: We have application that displays text with audio recorded material. We use Browser Control (Internet Explorer) in Delphi App to do this. We respond to events in Delphi code setting innerHTML for elements if we have to update the style ... Now, request is to add option to dynamically move the cursor or dynamically highlight the words spoken from the paragraph. It doesn't need to match absolutely the exact word spoken so we will have to dynamically update the content of position of highlighted word based on some timer or something (because it is not text to speach). What should be the most practical and easy approach to this kind of problem, all answers are greatly appreciated. Thanks.

• Invoke ngen from NSIS installer

  - by BlackStar

  I am using NSIS to deploy a .Net application. The installation/uninstallation process works fine, but I would like to add a final ngen step to improve startup performance. Unfortunately, Google didn't reveal any relevant material. It's unlikely that noone has ever done this before - maybe someone here has some idea? In the unlikely case that this is impossible to support without ugly hacks, I would be willing to use a different installer technology provided it can run on my Linux build server. (This rules out WiX, for example.) Any ideas?

• Does anyone have any EPiServer Exam Tips?

  - by gilles27

  Myself and some colleagues have just been told that we are all taking the EPiServer CMS certification exam on Friday. Having done some research on the web it does sound like a challenging exam - I've heard that only one in six people pass it. There doesn't seem to be much in the way of learning material, beyond what is described on the EPiServer site, this blog post and this blog post. Has anyone else out there passed recently and if so can they provide any hints or tips? Any help would be appreciated.

• VSTS Test Edition or HP's LoadRunner?

  - by Edward Leno

  I have had this debate with some peers off and on for a while. I am certified in the HP tools, but have been spending more and more time with VSTS Test Edition 2008. I am looking for opinions on what people think of the future of both products and how they compete. LoadRunner's strengths include its vast array of protocols supported. Unfortunately since HP took over from Mercury, they are beginning to lag behind, especially in the new internet spaces. VSTS Test, once very limited, is now quite impressive, especially in 2010. I don't know if it makes business sense, but I would love for VSTS Test to take on some additional protocols. Many of my clients would like to move away from HP and their licensing costs. Finally, I am looking for good resources for VSTS Test. I have been playing with it, but would like to see some dedicated courses/material, instead of just a part of the larger VSTS. Thanks!

• What is your best programmer joke?

  - by hmason

  When I teach introductory computer science courses, I like to lighten the mood with some humor. Having a sense of fun about the material makes it less frustrating and more memorable, and it's even motivating if the joke requires some technical understanding to 'get it'! I'll start off with a couple of my favorites: Q: How do you tell an introverted computer scientist from an extroverted computer scientist? A: An extroverted computer scientist looks at your shoes when he talks to you. And the classic: Q: Why do programmers always mix up Halloween and Christmas? A: Because Oct 31 == Dec 25! I'm always looking for more of these, and I can't think of a better group of people to ask. What are your best programmer/computer science/programming jokes?

• What are some best practices for structuring cherrypy apps?

  - by Omega

  I'm writing a cherrypy app and I was wondering what the best way is for structuring my handlers and code for larger applications? I realize assignment is simple trough cherrypy.root, but what are some practices for writing the handlers and assigning them? (Allow me to prove my confusion!) My initial thought is to write a standard handler class that infers a template to run based on the current URL or class/method combination. Then I would assign one instance of that handler multiple times to the path to create pages. I don't see this working however as the recursive references wouldn't work quite right. So, given the fact that I'm already drawing blanks on how my own source code should look, I'd love some pointers and examples! Feel free to ask some detailed questions for me to clarify. While there is plenty of cherrypy tutorial material out there, it tends to only scratch the surface.

• How do you use Linq2Sql in your applications ?

  - by this. __curious_geek

  I'm recently migrating to Linq2Sql and all my future projects would be done in Linq2Sql. Having said that, I researched a lot on how to properly plug-in Linq2Sql in application design. what to put at what layer ? Should I use DTOs over Linq2Sql entities ? I did not find any rock-solid material that really talked about one single thing and everyone had their own opinions and I found all of them justified right from their arguments. I'm looking forward to your ideas on how to integrate/use Linq2Sql in projects. My priority is maintenance[it should be maintenable and when multiple people work on same project] and scalabilty [it should have scope of evolution]. Thanks.

• Video Synthesis - Making waves, pattern, gradients...

  - by Nathan

  I'm writing a program to generate some trippy visuals. My code paints each pixel with a random blue value which loops at 0.04 second intervals. for (y = 0; y < 5.5; y += 0.2) { for (x = 0; x < 7.5; x += 0.2) { b = rand() / ((double) RAND_MAX); setPixelColor(x,y,r,g,b); } } I'd like to do more than just make blue noise... but my maths is a bit rusty, and Google isn't helping me much today, so it would be great if you could share anything you know about making waves, patterns, gradient animations, etc or links to such material.

• Efficiently making web pages from multiple servers

  - by james.bcn

  I want to create a service that allows diverse web site owners to integrate material from my web servers into content served from their own servers. Ideally the resulting web page would only be delivered from the web site owners server, and the included content would be viewed as being part of the site by Google - which I think would rule out iframes or client-side Javascript to get the content from my server (although I may be wrong about that?). Also the data wouldn't actually be updated that often, say once a day, so it would be inefficient to get the data from my web servers with every request. Finally, the method needs to be as simple as possible so that it is easy for web site owners to integrate into their own sites. Are there any good methods for doing this sort of thing? If not then I guess the simple way is with iframes or Javascript.

• using a texture mesh and wireframe mesh in threejs

  - by Andy Poes

  I'm trying to draw a wireframe mesh and a textured mesh in threeJS but when I have both added to my scene the textured mesh doesn't display. Code below: I'm having trouble creating two meshes that share the same geometry where one of the materials is wireframe and the other is a texture. If one of the materials is wireframe and the other is just a color fill it works fine- but as soon as I make the second material a texture it stops working. If I comment out scene.add( wireMesh ); then the textured mesh shows up. var wireMat = new THREE.MeshBasicMaterial( { color:0x00FFFF, wireframe: true, transparent: true, overdraw:true } ); var wireMesh = new THREE.Mesh(geometry, wireMat); scene.add( wireMesh ); var texture = texture = THREE.ImageUtils.loadTexture( 'textures/world.jpg' ); var imageMat = new THREE.MeshBasicMaterial( {color:0xffffff, map: texture } ); var fillMesh = new THREE.Mesh(geometry, imageMat); scene.add( fillMesh );

• Drupal: Content in blocks from node_reference fields?

  - by Marco

  After only a few weeks of working with Drupal I've come up with a recurring problem, which I don't really have an optimal solution to, so I'm hoping that someone here might be able to give some best practice pointers. What I have is a region inside my node.tpl.php, which is populated with blocks that display content from two different CCK fields of the type node_reference. This works fine when displaying a single node. The problem appears when I need to use a view. For example, lets say I have a news listing, and a single news item view. When I display the single news item I can use the news node node_reference field to reference whatever material I would like to have in my sidebar, but when on the news listing view I would like to reference nodes separately. What would be the best practice to solve this? I'm having a few ideas, but none seem like the logical choice, how would you do?

• RedDot with Lotus Notes support

  - by fredde

  Hi, First post here in SO. I have a question within the area of CMS (RedDot) and possible integration of some Lotus Notes functionality. I'm very fresh in both areas. From my short research (did not find very much material regarding RedDot) I got the following: Contents in RedDot CMS can be accessed (and modified?) via the RQL API. (basicly xml messages) There exists a API developed for Java (jRQL). Lotus Notes has a developer kit called Lotus Expeditor Toolkit. My vague question is something like this: Is it possible to integrate a some kind of "content approver/manager" or any other useful CMS functionality from Lotus Notes into the RedDot CMS system? In that case I was thinking of using the jRQL and Lotus Expediton Toolkit so that the back end is fully using Java. Or is there any better solution? Regards Fredrik

• Cinema4D XML scene not rendering texture

  - by George Profenza

  I was playing with the Cinema 4D command line options and ran into a problem that might not be specific to the command line options. I saved a basic scene(a textured cube) in two formats: the original .c4d(binary) format and .xml(Cinema 4D XML via File Export). the .c4d file renders with the texture applied, while the .xml file renders without the texture applied. I had a look at the xml file, and there is a node that holds a reference to the image used as texture, and there is another node which seems to store the pixels in xml. When I opened the .xml document in Cinema 4D, the document did store the material with the texture, but it was not applied to the object. Am I missing something when I export to XML ? How can I export a Cinema 4D XML that can render with the texture applied ?

• Windows API GUI programming

  - by genesys

  Hi! I'm working on a Project with outdated, very old looking GUI (the used GUI framework is more than 10 years old) Since the used programming language is Eiffel, there are almost no good libraries for GUI development. Although Wrappers for C libraries exist, it's not that easy to wrap something like Qt with them. The current GUI framework uses the Windows API to create windows, widgets and so on. But as stated - it's very old. Now i would like to learn more about how to use the Windows API directly to create state of the art GUI's Can someone recommend any reading material? Thanks!

• Rails, using jQuery without jrails

  - by ibuck

  Hello all, I have been trying to convert my rails 2.2.2 app over to jQuery, and would like so without using jrails. The only reference material I can find on the subject is Railscasts Episode 136. Ryan goes over how to use jQuery to post a form and handle the response in a .js.erb file. My questions is has anyone tried to use jQuery with .js.erb files with anchors as the trigger? As a replacement for "link_to_remote". I have gotten jQuery to do a .get to submit this link on click to the controller, but I cannot seem to get it to go into the .js.erb file. Thanks

• Is there any way to simplify a verbose SQL INSERT INTO(..) query?

  - by Soundar Rajan

  I have a table with one id (autonumber) field and 50 other fields. The table is normalized, these are 50 material properties etc. I want to copy a record from this table into the same table - only the autoincrement id will be different. The query I am using now is INSERT INTO tableName (field1,field2,....field50) SELECT field1,field2,....field50 from tableName WHERE autoid=1234; Note that I have to type in ALL the 50 field names, twice! Is there any way to shorten this query so I don't have to type all of them? Thanks.

• How to choose the right web application framework?

  - by thenextwebguy

  http://en.wikipedia.org/wiki/Comparison_of_web_application_frameworks Since we are ambitiously aiming to be big, scalability is important, and so are globalization features. Since we are starting out without funding, price/performance and cost of licences/hardware is important. We definitely want to bring AJAX well present in the web interface. But apart from these, there's no further criteria I can come up with. I'm most experienced with C#/ASP.net, PHP and Java, in that order, but don't turn down other languages (Ruby, Python, Scala, etc.). How can we determine from the jungle of frameworks the one that suits best our goal? What other questions should we be asking ourselves? Reference material: articles, book recommendations, websites, etc.?

• Android and SQLite using the SQLiteOpenHelper

  - by tunneling

  I have a SQLite database, and several tables within that database. I am developing a DBAdapter for each table within the database. (reference Reto Meier's Professional Android 2 Application Development, Listing 7.1). I am using the adb shell to interface with the database from the command line and see that the database is being populated as I expect. Occasionally, I want to drop a table so that I can ensure it's being built properly, from scratch. The problem is that SQLiteOpenHelper only checks to see if the database exists. Is there a typical solution to writing a helper to also see that the table(s) exists? Basically once I drop a table, the helper checks to see that the database exists and assumes all is well. Also, the CREATE_DATABASE string used in the reference above only creates the one table. Should I consider using the DBAdapter for an adapter to ALL of my tables? That doesn't seem as clean to me.

• Recommend an algorithms exercise book?

  - by Parappa

  I have a little book called Problems on Algorithms by Ian Parberry which is chock full of exercises related to the study of algorithms. Can anybody recommend similar books? What I am not looking for are recommendations of good books related to algorithms or the theory of computation. Introduction to Algorithms is a good one, and of course there's the Knuth stuff. Ideally I want to know of any books that are light on instructional material and heavy on sample problems. In a nutshell, exercise books. Preferably dedicated to algorithms rather than general logic or other math problems. By the way, the Parberry book does not seem to be in print, but it is available as a PDF dowload.

• Tutorials/Books on using Mono to develop RESTful webservices?

  - by max

  Hi, anyone out there got any pointers to good links/tutorials/books on developing webservices with Mono? In more detail, I am interested in using Mono from project start on a Linux host developing in C# using Visual Studio for development, ideally with remote debugging if that is realistic developing web-services in MONO accessible in a RESTful manner, returning JSON hiding the services processes behind an Apache access the services either via javascript/AJAX or from a thin script layer written in PHP scalability is important for me unit-testing of webservices Any recommendations for material I could sift through to get a good head-start? I might add that I'm C#/.NET savvy, but not in the context of web development. I've been using it since it came out, but mainly for internal server-client applications where the clients were Windows desktop apps and the communication layer was remoting or, sometimes, more low-level socket-based. Thanks, max

• Preserve data in .net mvc

  - by Wei Ma

  I am implementing a search module with result page support paging. The example provided by NerdDinner passes pagenumber as a parameter for the Index action, and the action uses the pagenumber to perform a query each time the user hit a different page number. My problem is that my search take many more criteria such as price, material, model number etc. than just simple pagenumber. Therefore, I would like to preserve the criteria after users' first submission, so that I only have to pass the pagenumber back and forth. Using ViewData is not possible because ViewData get cleared once it is sent to the View. Is there any good way to preserve the criteria data as I wish?
