• CSS just for most basic HTML

  - by Gerenuk

  I've read that my note system Wikidpad, which exports to very simple HTML, can use CSS (http://wikidpad.sourceforge.net/help/HtmlCss.html) The elements in the output are not more than basic headings, bullet points and tables. I'd like to try some kind of improved style, but I as I have no knowledge about CSS, so the best I can do is to save some Myfile.css to a directory :) However if I google "CSS template" I get all sorts of complicating results that I cannot make sense of :( Am I using wrong terminology? Can you suggest what I should search for or maybe you even know a ressource where a get a simple CSS file with some decent standard HTML elements. I do not wish to make custom adjustments.

• Any way to skip the huge apt-cache-update everytime a repository is added?

  - by Nirmik

  I keep adding atleast one repository per day.! I like new stuff and to personalise my Ubuntu. But now evertime I add a repository,the apt cache needs to be updated and its almost a 10-15min update everyday.! Moreover its a lot data consuming. Is there any way or workaround so that the repository is updated in the apt-cache without updating other stuff? Also,sometimes i do not wish to install some updates at the given point of time due to my bandwidth limitations.But then if i have to add a repository,the updates are all installed in the sudo apt-get update command.. Would like any help. The bandwidth limit is actually a major issue for me.! Thanx :)

• Serve most of a domain with Apache, but use mod_proxy to serve some URLs from Lighttpd

  - by Alex Pineda

  So we wish to host some pages on a new server with apache2, and embed some of our old content & functionality from another server with lighttpd in an iframe. I'm looking at this configuration from the apache docs (http://httpd.apache.org/docs/2.2/vhosts/examples.html#page-header) under "Using Virtual_host and mod_proxy" together. <VirtualHost *:*> ProxyPreserveHost On ProxyPass / http://192.168.111.2/ ProxyPassReverse / http://192.168.111.2/ ServerName hostname.example.com </VirtualHost> The only issue is that I want to proxy only on a subdomain, or even better, if I can keep the top domain and proxy only if the url contains a particular path ie. "/myprocess.php". So in essence the DNS will point to the apache2 as the "master router".

• Unity: Assigning a key to perform an action in the inspector

  - by Marc Pilgaard

  I am trying to write a simple piece of code in JavaScript where a button toggles the activation of a shield, by dragging a prefab with Resources.load("ActivateShieldPreFab") and destroying it again (Haven't implemented that yet). I wish to assign this button through the inspector, so I have created a string variable which appears as intended in the inspector. Though it doesn't seem to register the inspector input, even though I changed the value through the inspector. It only provides the error: "Input Key named: is unknown" When the button name is assigned within the code, there is no issues. Code as follows: var ShieldOn = false; var stringbutton : String; function Start(){ } function Update () { if(Input.GetKey(stringbutton) && ShieldOn != true) { Instantiate(Resources.load("ActivateShieldPreFab"), Vector3 (0, 0, 0), Quaternion.identity); ShieldOn = true; } }

• How do you visually represent programming skills?

  - by TomSchober

  I had a discussion with a recruiter recently that made me wish I could visually represent programming skills. In trying to explain how skills relate, what are the important properties of those skills? Would a tagging model work (i.e. "Design Pattern," "Programming Language," "IDE," or "VCS")? Are they really hierarchical? Clarification: The real problem I see is communicating the level of granularity among skill sets. For instance saying someone "knows Java" is a uselessly broad term in describing what someone can DO. However saying they know how to write web services with the Java Programming language is a bit better. To go even further, saying they know Spring as a tool under all that is probably specific enough. What should we call those levels of granularity? What are the relationships between the terms we use? i.e. Framework to Language, Tool to Language, Framework to Solution(like web services), etc.

• Book: Pro SQL Server 2008 Service Broker: Klaus Aschenbrenner

  - by Greg Low

  I've met Klaus a number of times now and attended a few of his sessions at conferences. Klaus is doing a great job of evangelising Service Broker. I wish the SQL Server team would give it as much love. Service Broker is a wonderful technology, let down by poor resourcing. Microsoft did an excellent job of building the plumbing for this product in SQL Server 2005 but then provided no management tools and no prescriptive guidance. Everyone then seemed surprized that the takeup of it was slow. I even...(read more)

• 2D Planet Gravity

  - by baked

  I'm trying to make a simple game where a spaceship is launched and then its path is effected by the gravity of planets. Similar to this game: http://sciencenetlinks.com/interactives/gravity.html I wish to know how to replicate the effect the planets have on the spaceship in this game so a spaceship can 'loop' around a planet to change direction. I have managed to achieve some bogus results where the spaceship loops in a huge ellipse around the planet or is only slightly affected by the gravity of a planet using Vectors. Thanks in advance. p.s I have plenty of coding experience just none to do with game dev.

• Mobile 3D engine renders alpha as full-object transparency

  - by Nils Munch

  I am running a iOS project using the isgl3d framework for showing pod files. I have a stylish car with 0.5 alpha windows, that I wish to render on a camera background, seeking some augmented reality goodness. The alpha on the windows looks okay, but when I add the object, I notice that it renders the entire object transparently, where the windows are. Including interior of the car. Like so (in example, keyboard can be seen through the dashboard, seats and so on. should be solid) The car interior is a seperate object with alpha 1.0. I would rather not show a "ghost car" in my project, but I haven't found a way around this. Have anyone encountered the same issue, and eventually reached a solution ?

• Using raw vertex information for sprites rather than SpriteBatch in XNA

  - by The Communist Duck

  I have been wondering whether using SpriteBatch is the best option. Obviously for prototyping or small games it works well. However, I've been wanting to apply techniques such as shaders and lighting to my game. I know you can use shaders to some extent with SpriteSortMode.Immediate, but I'm not sure if you lose power using that. The other major thing is that you cannot store your vertex data in the graphics memory with buffers. In summary, is there an advantage of using VertexTextureNormal (or whatever they're called) structs for vertex data for 2D sprites, or should I stick with SpriteBatch, provided I wish to use shaders?

• How should we approach publishing our game from India?

  - by Praveen Sharath

  Me and my friends are developing a game using Java for Windows operating system. We have nearly completed our game. As we feel that the game can make money, we wish to sell it. But in India we don't know any game publishing company. We want to know the following if possible. Will game publishers like BigFishGames.com publish our game even though we are not in USA? We are just students in college. Is it required that we can sell only after we start a company? Is it possible to sign contracts if the publisher wishes to publish our game, while the publisher and developer are in different countries? Thank you

• Cool examples of procedural pixel shader effects?

  - by Robert Fraser

  What are some good examples of procedural/screen-space pixel shader effects? No code necessary; just looking for inspiration. In particular, I'm looking for effects that are not dependent on geometry or the rest of the scene (would look okay rendered alone on a quad) and are not image processing (don't require a "base image", though they can incorporate textures). Multi-pass or single-pass is fine. Screenshots or videos would be ideal, but ideas work too. Here are a few examples of what I'm looking for (all from the RenderMonkey samples): PS - I'm aware of this question; I'm not asking for a source of actual shader implementations but instead for some inspirational ideas -- and the ones at the NVIDIA Shader Library mostly require a scene or are image processing effects. EDIT: this is an open-ended question and I wish there was a good way to split the bounty. I'll award the rep to the best answer on the last day.

• Help comparing Cocos2d and Unity3d for this project.....

  - by Omega

  I will not go into details, but I would like to hear your opinions about this: Essentially, my project will be a 2d game, with lots of complex levels, where some might be simple and others might be a bit more deep, with physics, etc. We want to implement our very own online structure: logging in, leaderboards, achievements, friends etc with our own servers. This means no OpenFeint nor GameCenter at all. We expect this game to be very large in both graphics and audio. We wish to use in-app purchases. Now, we considered two options. Cocos2d and Unity3d. We need help deciding using the factors I mentioned before (networking, good performance even for a large game in terms of graphics and audio like this, in-app purchases, etc) which option would fit better this? Technically, both options can create 2d games. I'd like to hear your opinion.

• In Search of Automatic ORM with REST interface

  - by Dan Ray

  I have this wish that so far Google hasn't been able to fulfill. I want to find a package (ideally in PHP, because I know PHP, but I guess that's not a hard requirement) that you point at a database, it builds an ORM based on what it finds there, and exposes a REST interface over the web. Everything I've found in my searches requires a bunch of code--like, it wants you to build the classes for it, but it'll handle the REST request routing. Or it does database and relational stuff just fine, but you have to build your own methods for all the CRUD actions. That's dumb. REST is well defined. If I wanted to re-invent the wheel, I totally could, but I don't want to. Isn't there somebody who's built a one-shot super-simple auto-RESTing web service package?

• How do I get a Netgear WNDA3100V2 working?

  - by Michal

  I have Ubuntu 11.10 on my desktop. A month ago I bought Linksys AE1000 adapter,I did not check that it's not working on Ubuntu and because I've lost receipt I'm stuck with it. Last week I bought Netgear adapter and this time I did check and it meant to be plug an play but it was not. I have checked many forums and managed to install software, system does sees adapter but it's not connecting to network. I have found that it may not like WPA so I have created my own password-letters and digits,no spaces-still nothing.I don't understand why. This is my next attempt with Linux and I'm not with IT background so it takes time and research before I can resolve something but I really want to learn. I so wish to learn on Ubuntu.One day, I've checked Fedora16 and my old Linksys AE1000 worked without any instalations.

• Why does Ubuntu Download recommend 32-bit install?

  - by Warren Pena

  The Ubuntu desktop download screen has a pair of radio buttons you use to select whether you wish to download the 32-bit or 64-bit version. The 64-bit version is labeled "Not recommended for daily desktop usage." If you have a 64-bit processor, why would you not want to use the 64-bit version of Ubuntu? Update for 10.10: They've removed the "Not recommended" label from the 64-bit version and added a "Recommended" label to the 32-bit version. Update for 11.04: Same as 10.10. Update for 12.04: Still says "Recommended" next to 32-bit version of desktop

• TTS on App Engine

  - by yati sagade

  I have written a small front-end to the Festival TTS system using Python/Django. I wish to deploy it on the Google App Engine cloud. A few questions: My application uses the Festival app 'text2wave'. Will is work on the cloud? I have used Python primitives like subprocess.call() to invoke the aforementioned program. Will that work? If your answer to any or both of (1) and (2) is no, is there a free api on the web that I can use (from the appengine)? I read somewhere about placing calls from Phono to a Voxeo backend, but I'm not sure what that means. I am aware of the Google Translate extension that allows translation using an HTTP GET (REST) request, but here the text is limited to 100 chars. Bad. Plus, they may take it down any point of time.

• Pong Collision Help in C# w/ XNA

  - by Ramses Brown

  Edit: My goal is to have it function like this: Ball hits 1st Quarter = rebounds higher (aka Y++) Ball hits 2nd Quarter = rebounds higher (using random value) Ball hits 3rd Quarter = rebounds lower (using random value) Ball hits 4th Quarter = rebounds lower (aka Y--) I'm currently using Rectangle Collision for my collision detection, and it's worked. Now I wish to expand it. Instead of it simply detecting whether or not the paddle/ball intersect, I want to make it so that it can determine what section of the paddle gets hit. I wanted it in 4 parts, with each having a different reaction to impact. My first thought is to base it on the Ball's Y position compared to the Paddle's Y position. But since I want it in 4 parts, I don't know how to do that. So it's essentially be if (ball.Y > Paddle.Y) { PaddleSection1 == true; } Except modified so that instead of being top half/bottom half, it's 1st Quarter, etc.

• What terminal emulators are available for heavy terminal users?

  - by Noah Goodrich

  I spend a lot of time at the command-line during the workday and at home too since I run Ubuntu exclusively. I've been using the default gnome terminal but I've reached a point where I'd really like to get my terminal tricked out so that my common tasks are as easy as possible. Specifically, I find that I spend of lot of time browsing code in the terminal and working in config files. On my wish list would be: Ability to have multiple screens, tabs, windows (I don't have a preference at this point) that I can easily switch between. Color coding for everything Easy to modify the aesthetics of the terminal (is it vain to want my terminal to look nice?) such as transparency, borders, etc.

• Read only array, deep copy or retrieve copies one by one? (Performance and Memory)

  - by Arthur Wulf White

  In a garbage collection based system, what is the most effective way to handle a read only array if such a structure does not exist natively in the language. Is it better to return a copy of an array or allow other classes to retrieve copies of the objects stored in the array one by one? @JustinSkiles: It is not very broad. It is performance related and can actually be answered specifically for two general cases. You only need very few items: in this situation it's more effective to retrieve copies of the objects one by one. You wish to iterate over 30% or more objects. In this cases it is superior to retrieve all the array at once. This saves on functions calls. Function calls are very expansive when compared to reading directly from an array. A good specific answer could include performance, reading from an array and reading indirectly through a function. It is a simple performance related question.

• How to protect SHTML pages from crawlers/spiders/scrapers?

  - by Adam Lynch

  I have A LOT of SHTML pages I want to protect from crawlers, spiders & scrapers. I understand the limitations of SSIs. An implementation of the following can be suggested in conjunction with any technology/technologies you wish: The idea is that if you request too many pages too fast you're added to a blacklist for 24 hrs and shown a captcha instead of content, upon every page you request. If you enter the captcha correctly you've removed from the blacklist. There is a whitelist so GoogleBot, etc. will never get blocked. Which is the best/easiest way to implement this idea? Server = IIS Cleaning out the old tuples from a DB every 24 hrs is easily done so no need to explain that.
