• Resize content for "frame" on .aspx page which draws product content from suppliers' page

  - by zenbike

  I have a retail store site, no online sales, which displays the webpage of our supplier in a "frame" in order to have the most accurate and up to date information for our customers. (example) My issue is that the size of the page it is pulling in doesn't fit in the frame. It looks pretty poor, and part of the content is obscured. Is there a way to scale the content drawn in to the size of the frame? The same site also has an intermittent issue with the Flash banner loading. When it doesn't load, the layout of the header on the page is awful. Any ideas there will also be appreciated.

• MAAS and Openstack Network

  - by user281985

  Trying to figure out the best way for openstack and MASS networks to co-exist. Assuming MAAS used 10.0.0.0/24 for provisioning of various openstack nodes, once openstack, with quantum, is deployed should 10.0.0.0 be used as management network, external network, both or discarded? Reason for the question being that I ran a deployment where openstack used 10.0.0.0 as its management network, MAAS dhcp and dns were active; however, I could only access VMs through namespace and was not able to utilize MAAS's dhcp to assign floating IP. (VMs network was through an internal bridge 10.10.10.10, and external bridge was using the same interface as MAAS.) Any thoughts or ideas are appreciated.

• Searching for a page with a Very Unique title, doesnt find that intended page... Why?

  - by Sam

  Dear folks, a question about appearing in search results in google: A page of mine has this extremely unique page title: Ein gutes Logo passt wie ein Handschuh auf Ihre Marke in die Hände Now, when I search the phrase: Ein gutes Logo passt wie ein Handschuh auf Ihre Marke in die Hände Then all kinds of other irrelevant pages show up having only 1 or at best two words from my unqie title appearing, although I have searched for the entire phrase! And when I search the phrase in between quotes: "Ein gutes Logo passt wie ein Handschuh auf Ihre Marke in die Hände" Then it finds 1 result, which is my page. What is going on? Why doesn't show the unique result without the quotes? Thanks: your ideas and suggestions are welcome and much appreciated

• Adaptive Characters: AI Solution Needs a Problem

  - by Roger F. Gay

  Have sophisticated adaptive programming, will travel - so to speak. I'm part of a group that developed sophisticated learning / adaptive software for robotics. The system "thinks" via its simulator, building and adapting code on its own; and then carries out the best solution. The software can also adapt to new situations, etc. http://mensnewsdaily.com/2007/05/16/robobusiness-robots-with-imagination/ It's easy to imagine using it with automated game characters that will adapt to the players moves and style - the easiest example would be fighting. The more the simulated fighter fights with the human player, the more it learns to counter that players fighting skills. But there should be more. Anyone have any ideas as to how adaptive characters might be interesting in games?

• XNA frame rate spikes in full screen mode

  - by ProgrammerAtWork

  I'm loading a simple texture and rotating it in XNA, and this works. But when I run it in full screen 1920x1080 mode I see spikes while my texture is rotating. If I run it windowed with 1920x1080 resolution, I don't get the spikes. The size of the texture does not seem to matter, I tried 512 texture size and 2048 texture size, same thing happens. Spikes in full screen, no spikes in windowed, resolution does not seem to matter, Debug or Release does not seem to do anything either. Anyone got ideas of what could be the problem? Edit: I think this problem has something to do with the vertical retrace. Set this property: _graphicsDeviceManager.SynchronizeWithVerticalRetrace = false; you'll lose vsync but it will not stutter.

• Design patterns for effects between actors and technology

  - by changelog

  I'm working on my first game, and taking the opportunity to brush up my C++ (I want to make as much of it as portable as I can.) Whilst working on the technology tree and how it affects actors (spaceships, planets, crew, buildings, etc) I can't find a pattern that decouples these entities enough to feel like a clean approach. Just as an idea, here's the type of effects these actors can have on one another (and techs too) An engineer inside a spaceship boosts its shield A hero in a spaceship in a fleet increases morale A technology improves spaceships' travel distance A building in a planet improves its production The best I can come up with is the Observer pattern, and basically manage it more or less manually (when a crew member enters a spaceship, fire the event; when a new building is built in a planet, fire the event, etc etc.) but it seems to be too tightly coupled to me. I would love to get some ideas about how to approach this better.

• Netbeans shows only blank window

  - by aGr

  I am not able to launch Netbeans. When I launch it for the first time I normally get the netbeans splash screen, but after that nothing happens. When I try to launch it again, a small blank window appears. I am able to enlarge the window, but it is completely blank. Any ideas? As far as I remember this didn't come after some update/new install or whatever. Netbeans worked perfectly, but then all from the sudden...

• Any board-like platform but only for files instead of text posts? [on hold]

  - by Janwillhaus

  I am looking for a (best open-source or free but also commercially available) CMS platform that is built similarly to bulletin boards (for example phpBB) but instead of text posts, registered users can upload files that can be rated, commented etc.) I am aware of the number of board CMSes that have file-database plugins, but that is not what I want. I want to have a system that focuses on the files rather than on the postings. Or do you have any alternative ideas on solutions to the problem? I need the following functions CMS focused on file management Files that can be categorized (in a tree-like view for example) Comments and ratings can be added to files Users that can be provided various rights around the platform (moderation, commenting, exclusion of non-registered users, etc.) Users can upload files themselves (for further moderation

• How to work with scenes in a 2D game

  - by Anearion

  I'm a java/android programmer, but I don't have any experience in game programming, I'm already reading proper books, like "Pro Android Games", but my concerns are more about the ideas behind game programming than the techniques themselves. I'm working on a 2D game, something like Cluedo to let you understand the genre. I would like to know how should I act with the "scenes", for example, a room with a desk, TV, windows and a lamp. I need to make some items tappable and others not. Is it common to use one image (invisible to the user) with every different item a different color, then call the getColor() method on the image? Or use one image as background, and separate images for all the items? If the latter, how can I set the positioning? and should I use imageView or imageButton? I'm sorry if those are really low quality questions, but as "outsider" ( I'm 23 and still finishing my university ) it's pretty hard learn alone.

• What is the best way to promote a programming blog?

  - by paul

  (The guys from 'Programmers' referred me here...) How do you promote your programming blog? I recently started http://blackforestcoder.blogspot.com/ to record my progress working with new technologies and ideas. The main aim being to provide a list of pitfalls and solutions and also to get feedback from readers. Since I set it up 10 days ago I have only had about 2-3 hits even though Google is supposed to be indexing it. How might I boost the hit rate?

• What can I put in my software development blog to make it a good showcase of me?

  - by Sean

  I have been itching to write a software development blog for some time now. The best advice I've received about blog writing is "Write the blog you would have want to read". Its good advice but its only half the story, Once you write a blog it becomes your showcase on the Internet, it is bound to come up on any search conducted by a future colleague or employer. It can be a good thing or it can do some serious damage. So if there are any hiring managers out there, can you give me a few pointers on what it is in a blog that give you a good impression about candidate and/or the kind of stuff that causes you to throw the candidate's resume to the nearest bean? Does a blog have to come up with a clever piece of code every week? (Don’t think I can manage it) Is it OK to blog more then not about development methods to improved quality and productivity (have a lot of ideas about that). Can I blog about stuff I did not try first hand but seems noteworthy?

• How to present an Android Augmented Reality application?

  - by Egor

  I'm currently working on my diploma project - an application for Android that uses the Augmented Reality technology. I'll have to make a presentation of my app and I can't really think of a way to show this kind of application to the crowd. Anyone has ideas? Will really appreciate an elegant solution! EDIT The application shows users the information about the places around, some kind of Layar + Google Places. So the issue is that to use the application you must turn around with your device in hands to see the icons on the screen. Presentation would have been easier if I could just lay the device on the table and use the app.

• Grapeshot crawler ignoring robots.txt

  - by QF_Developer

  Has anyone come across a crawler called Grapeshot? They are hammering the same page repeatedly on our website. I believe they are looking for ad related keywords, based on previous content ad campaigns. The odd thing is we never ran any such campaigns on the page they are so interested in. We do have only a few pages running AdSense, is this what has attracted Grapeshot? I've added the following declaration to my robots.txt, but they don't seem to be honouring it? User-agent: grapeshot Disallow: / Any ideas on how to block this nuisance crawler? I'm starting to think the best way is by setting up IP rules in IIS?

• How to unit test image processing code?

  - by rold2007

  I'm working in image processing (mainly OCR) and I wonder how I should integrate unit tests in my development. I'm already using unit tests for more "common" type of code but when dealing with image processing code I'm not sure how to deal with it. This kind of code always need some image data input/output and mocking this is not obvious. For now I'm mostly doing integration tests but they take a while to run and I would like some ideas on how to break down this kind of code into unit tests so that I can run them more quickly.

• Gnome panel hides window titlebar.

  - by Xorty

  I moved my laptop screen "below" external screen (was using left/right config before). There's a little problem. When my gnome panel is on top of laptop screen, all windows I maximize "drawn" under top gnome panel. Therefore, I cannot see window titlebar. I tried suggested fixes as metacity --replace and so on, but none worked. When I move my taskbar to bottom it works just fine. Any ideas? Thank you.

• Checking for alternate keys with XNA IsKeyDown

  - by jocull

  I'm working on picking up XNA and this was a confusing point for me. KeyboardState keyState = Keyboard.GetState(); if (keyState.IsKeyDown(Keys.Left) || keyState.IsKeyDown(Keys.A)) { //Do stuff... } The book I'm using (Learning XNA 4.0, O'Rielly) says that this method accepts a bitwise OR series of keys, which I think should look like this... KeyboardState keyState = Keyboard.GetState(); if (keyState.IsKeyDown(Keys.Left | Keys.A)) { //Do stuff... } But I can't get it work. I also tried using !IsKeyUp(... | ...) as it said that all keys had to be down for it to be true, but had no luck with that either. Ideas? Thanks.

• OpenGL 2D Rasterization Sub-Pixel Translations

  - by Armin Ronacher

  I have a tile based 2D engine where the projection matrix is an orthographic view of the world without any scaling applied. Thus: one pixel texture is drawn on the screen in the same size. That all works well and looks nice but if the camera makes a sub-pixel movement small lines appear between the tiles. I can tell you in advance what does not fix the problem: GL_NEAREST texture interpolation GL_CLAMP_TO_EDGE What does “fix” the problem is anchoring the camera to the nearest pixel instead of doing a sub-pixel translation. I can live with that, but the camera movement becomes jerky. Any ideas how to fix that problem without resorting to the rounding trick I do currently?

• #altnetseattle in Closing

  - by GeekAgilistMercenary

  So again, the #altnetseattle Conference easily was one of the most useful events of the year for me.  The amount of ideas, thoughts, and conversations that happen in just those two days often outweigh all the presentations I see at other conferences throughout the year.  The reason is simple, they are directed, to the point, and done with the ideal of open spaces.  This makes each session exhaustive on a particular topics.  Throw together some of the smartest people in the field and you have a bang up awesome energy and conversation. I got to talk about cloud computer, a little bit, and REST Architecture as sessions I kicked off myself.  Those were a blast.  I also got to meet a ton of other super talented like minded developers and engineers that are out there kicking the tires of .NET (and other languages/tech stacks like Ruby on Rails). Overall the conference rocked and I will definitely be coming back!  With that, I am headed home to Portland.

• Second gen ipod shuffle not working with rhythmbox

  - by richzilla

  hi all, I'm trying to get a second gen ipod shuffle to work with Ubuntu 10.10. As far as i understand Rhythymbox should support this. When I plug the ipod in it shows up under the devices section of the menu, but after that I am unable to do anything with it. I can't see the songs that are already on it, I can't add new songs, I can't do anything. When i attempt to drag a song across, absolutely nothing happens. if i try the sync with library option, it shuts rhythymbox down completely. Any ideas would be greatly appreciated.
