• Adsense alternative for a "Sex Education" website?

  - by WhatIsOpenID

  I am creating a nice and niche "Sex Education" website. No porn, nothing offensive and no scams. I would love to place Google Adsense but they do not allow ads on adult sites. I would like to know what advertising and link-exchange like should I place on my site. My sole objective is to cover the server costs and salary of one or two persons. (In this way, it is different from Best alternative to Adsense for a small website?).

• Programming language specific package management systems

  - by m0nhawk

  There are some programming languages for which exist their own package management systems: CTAN for TeX CPAN for Perl Pip & Eggs for Python Maven for Java cabal for Haskell Gems for Ruby Is there any other languages with such systems? What about C and C++? (that's the main question!) Why there are no such systems for them? And isn't creating packages for yum, apt-get or other general package management systems better? UPD: And what about unification? Have someone tried to unify that "the zoo"? If yes, looks like that project didn't succeed.

• ALL, ALLEXCEPT and VALUES in DAX

  - by Marco Russo (SQLBI)

  When you use CALCULATE in DAX you are creating a new filter context for the calculation, based on the existing one. There are a few functions that are used to clear or preserve a column filter. These functions are: ALL – it can be used with one or more columns from a table, or with the name of a table. It returns all the values from the column(s) or all the rows from the table, ignoring any existing filter context. In other words, ALL clear an existing filter context on columns or table. We can use...(read more)

• Construct sentences from tabular data

  - by Sumeet

  I have a huge set of html files an have to retrieve the meaningful information from them. Most of the task is accomplished, now the problem is with HTML tables. I have some literature on how to extract meaningful tables from html, but my problem is with creating meaningful sentences from tabular data (or attribute value pairs extracted from a table). Are there any NLP/Machine learning techniques to do this? Here is what I expect. Suppose below is a sample table: col_Name: Sumeet col_year: 2011 col_winner: quiz Can this be made to something meaningful like "Sumeet won quiz in 2011"?

• PostgreSQL, Ubuntu, NetBeans IDE (Part 2)

  - by Geertjan

  Now let's create the start of a CRUD application on the NetBeans Platform, using Hibernate and PostgreSQL to do so. Here's what I see in NetBeans IDE after setting things up as outlined yesterday: The NetBeans Platform CRUD Tutorial should get you up and started creating the NetBeans Platform application. Open the generated "persistence.xml" in Design mode and then switch the persistence library to Hibernate. The Here's the application structure: The Hibernate module that you see above has this content: Here's the result: And here's the source code: http://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.3/misc/NBPostgreSQL

• How to set sprite source coordinates?

  - by ChaosDev

  I am creating own sprite drawer with DX11 on C++. Works fine but I dont know how to apply source rectangle to texture coordinates of rendering surface(for animation sprite sheets) //source = (0,0,32,64); //RECT D3DXVECTOR2 t0 = D3DXVECTOR2( 1.0f, 0.0f); D3DXVECTOR2 t1 = D3DXVECTOR2( 1.0f, 1.0f); D3DXVECTOR2 t2 = D3DXVECTOR2( 0.0f, 1.0f); D3DXVECTOR2 t3 = D3DXVECTOR2( 0.0f, 1.0f); D3DXVECTOR2 t4 = D3DXVECTOR2( 0.0f, 0.0f); D3DXVECTOR2 t5 = D3DXVECTOR2( 1.0f, 0.0f); VertexPositionColorTexture vertices[] = { { D3DXVECTOR3( dest.left+dest.right, dest.top, z),D3DXVECTOR4(1,1,1,1), t0}, { D3DXVECTOR3( dest.left+dest.right, dest.top+dest.bottom, z),D3DXVECTOR4(1,1,1,1), t1}, { D3DXVECTOR3( dest.left, dest.top+dest.bottom, z),D3DXVECTOR4(1,1,1,1), t2}, { D3DXVECTOR3( dest.left, dest.top+dest.bottom, z),D3DXVECTOR4(1,1,1,1), t3}, { D3DXVECTOR3( dest.left , dest.top, z),D3DXVECTOR4(1,1,1,1), t4}, { D3DXVECTOR3( dest.left+dest.right, dest.top, z),D3DXVECTOR4(1,1,1,1), t5}, };

• Simple script - execute command on selected file

  - by askmoo

  I want to make a script that will execute .jar file on selected file. Later I will add that script to right-click menu via the tool Nautilus Actions or just place it into nautilus-scripts folder. I have a problem creating script. When I am in a usual console screen and want to execute this jar file on any other file, I use this syntax myfile.jar ./someotherfile.xml and the jar file will write the output to the console screen. So I created a file script.sh, added lines in it #!/bin/bash /home/username/myfile.jar $1 But it does not output anything. I know I am doing something wrong. Please help. To sum, I need a script that will use selected file as a parameter, open the gnome-terminal, inside that terminal it will start JAR file and pass it the selected file. I am confident that this is a very simple procedure, but I am total newbie with shell scripting.

• Netbeans IDE did work after installation, but doesn't start after restart.

  - by ubuntumazze

  i installed Netbeans on Ubuntu 11.10 following these instructions: http://pasindudps.blogspot.com/2011/10/installing-netbeans-ide-in-ubuntu-1110.html. It worked perfectly fine (creating projects, open projects, compile, run...) but after restarting netbeans started normally and it is shown as a running application in unity-panel but I can't access the programm. I uninstalled and reinstalled it, it worked once but failed after restart. Has anyone an idea what might be the problem here? Thanks in advance. Regards

• How to avoid being an API programmer only?

  - by anything

  I have almost six years of experience in java. I have developed many projects which used frameworks like Struts, Spring, Hibernate, JQuery , DWR, Ajax etc. I have used these technologies in almost all the projects I have worked on. Projects were very simple mostly with crud based apps. My everyday tasks involves creating few screens, writing queries, testing etc. After all these years I feel like I have turned into an API programmer who just uses these above mentioned frameworks which is not giving me any satisfaction of being a programmer. Is this normal or is it just me who is feeling like this?

• Create a screencast in a low end PC, but fast (maybe by sacrificing compression ?)

  - by josinalvo

  As the title suggests, I am asking a lot. We've been trying to generate some screencasts on my eeepc. recordmydesktop is doing the job decently, but only if allowed time to "compile" the video afterwards. If we ask it to do "on the fly", video and audio get out of sync. Now, we are creating many screencasts as practice (and like to watch them after, to criticize). Reducing quality is undesirable, because eventually a good practice run becomes the one we'll release. So we'd like a way to do screencasts "on the fly", with decent quality, on the low end machine. As nothing is ever free, we are willing to sacrifice: we don't care too much about compression: 20GB for a 15min video is acceptable

• C# Timers for game development

  - by Valentin

  Hi, all! I want to find out the best way of creating time based events in games. Lets talk for example about Texas Holdem Poker. Server can handle thousands of tables and in every table we have timers: turn timer, hold seat timer and so on. What is the best way of timers realization for this purpose? Is System.Timers.Timer class can handle this or it will be more reasonable to create a separate thread with sorted time queue (for example an ascending sorted list with int values which represent time in ms remained)? Thanks in advance, Valentin

• XRDP crashes when using xfce desktop

  - by user291721

  I've been struggling with this for a few days. Currently using Ubuntu 14.04. I started out trying to use VNC and could connect but only received a black and white checkered screen when connecting using tightvnc from my windows machine. Seems that applications seem to have issues interpreting the gnome graphics. I then tried XRDP and received the same issue but was able to find enough information to get by this issue. After creating a .xsession file and setting the desktop to spawn an xfce4-session I was able to connect and the desktop displays, at least for a few seconds. After a couple seconds rdp crashes and I'm unable to connect again until I restart the xrdp service. Any help would be appreciated. Thanks

• How important is to avoid name collisions between libraries belonging to different domains?

  - by Sergio

  I have written a small open source Java library for facilitating conversions between different types of objects (in the style of Google's gson, but quite more general). It seems to me that a nice natural name for my library is JConverter, after browsing in the web to see if another library with the same name already exists, I found a library with the same name for Joomla. My concrete question is: How important is to avoid naming collisions when creating an open source library if an existing library with the chosen name already exists in a complete different domain ? (in my concrete case, these are libraries even implemented for different languages).

• Ideas for card deck names [closed]

  - by Milan Babuškov

  I'm creating a card game, and wish to offer players to choose from different sets of playing cards. The game logic remains the same, only the design and graphics on the cards would be different. It would feature classic French set, German/Hungarian one, and a bunch of other custom designed ones. I'm looking for some cool names to give to those sets. I thought maybe to use names of some world cities like "London set", "Paris set", "Tokyo set", but there might be something better. I know this is really open-ended question, so there might not be a definitive "correct" answer, but I hope this kind of brainstorming would be useful to anyone looking for ideas to name a set of... well, anything. I'll up-vote any good idea, no matter if I don't end up using any of those.

• Adding a short delay between bullets

  - by Sun

  I'm having some trouble simulating bullets in my 2D shooter. I want similar mechanics to Megaman, where the user can hold down the shoot button and a continues stream of bullets are fired but with a slight delay. Currently, when the user fires a bullet in my game a get an almost laser like effect. Below is a screen shot of some bullets being fired while running and jumping. In my update method I have the following: if(gc.getInput().isKeyDown(Input.KEY_SPACE) ){ bullets.add(new Bullet(player.getPos().getX() + 30,player.getPos().getY() + 17)); } Then I simply iterate through the array list increasing its x value on each update. Moreover, pressing the shoot button (Space bar) creates multiple bullets instead of just creating one even though I am adding only one new bullet to my array list. What would be the best way to solve this problem?

• I am the Webmaster now. Where do I start? [closed]

  - by John C

  I just changed jobs and will soon be in charge of a custom-built ASP.NET CMS and website for a fairly large corporation with global offices. I have IT and developer FTE resources available to me but I am trying to build a list of branding, project, and functionality points to review. What guides or lists can/should I use to evaluate this website before I begin adding features, creating new projects, or even redesigning and redeveloping the site? (I have been a webmaster/designer/developer for small, WordPress/Drupal sites for 10 years. I have been an unofficial webmaster (director/content manager) for a large site for 3 years (no direct development control over Sharepoint administration, IIS, or hosting ... but everything else, I did. Analytics, email, advertising, social, SEO, etc.).) Thank you!

• Is it feasible and useful to auto-generate some code of unit tests?

  - by skiwi

  Earlier today I have come up with an idea, based upon a particular real use case, which I would want to have checked for feasability and usefulness. This question will feature a fair chunk of Java code, but can be applied to all languages running inside a VM, and maybe even outside. While there is real code, it uses nothing language-specific, so please read it mostly as pseudo code. The idea Make unit testing less cumbersome by adding in some ways to autogenerate code based on human interaction with the codebase. I understand this goes against the principle of TDD, but I don't think anyone ever proved that doing TDD is better over first creating code and then immediatly therafter the tests. This may even be adapted to be fit into TDD, but that is not my current goal. To show how it is intended to be used, I'll copy one of my classes here, for which I need to make unit tests. public class PutMonsterOnFieldAction implements PlayerAction { private final int handCardIndex; private final int fieldMonsterIndex; public PutMonsterOnFieldAction(final int handCardIndex, final int fieldMonsterIndex) { this.handCardIndex = Arguments.requirePositiveOrZero(handCardIndex, "handCardIndex"); this.fieldMonsterIndex = Arguments.requirePositiveOrZero(fieldMonsterIndex, "fieldCardIndex"); } @Override public boolean isActionAllowed(final Player player) { Objects.requireNonNull(player, "player"); Hand hand = player.getHand(); Field field = player.getField(); if (handCardIndex >= hand.getCapacity()) { return false; } if (fieldMonsterIndex >= field.getMonsterCapacity()) { return false; } if (field.hasMonster(fieldMonsterIndex)) { return false; } if (!(hand.get(handCardIndex) instanceof MonsterCard)) { return false; } return true; } @Override public void performAction(final Player player) { Objects.requireNonNull(player); if (!isActionAllowed(player)) { throw new PlayerActionNotAllowedException(); } Hand hand = player.getHand(); Field field = player.getField(); field.setMonster(fieldMonsterIndex, (MonsterCard)hand.play(handCardIndex)); } } We can observe the need for the following tests: Constructor test with valid input Constructor test with invalid inputs isActionAllowed test with valid input isActionAllowed test with invalid inputs performAction test with valid input performAction test with invalid inputs My idea mainly focuses on the isActionAllowed test with invalid inputs. Writing these tests is not fun, you need to ensure a number of conditions and you check whether it really returns false, this can be extended to performAction, where an exception needs to be thrown in that case. The goal of my idea is to generate those tests, by indicating (through GUI of IDE hopefully) that you want to generate tests based on a specific branch. The implementation by example User clicks on "Generate code for branch if (handCardIndex >= hand.getCapacity())". Now the tool needs to find a case where that holds. (I haven't added the relevant code as that may clutter the post ultimately) To invalidate the branch, the tool needs to find a handCardIndex and hand.getCapacity() such that the condition >= holds. It needs to construct a Player with a Hand that has a capacity of at least 1. It notices that the capacity private int of Hand needs to be at least 1. It searches for ways to set it to 1. Fortunately it finds a constructor that takes the capacity as an argument. It uses 1 for this. Some more work needs to be done to succesfully construct a Player instance, involving the creation of objects that have constraints that can be seen by inspecting the source code. It has found the hand with the least capacity possible and is able to construct it. Now to invalidate the test it will need to set handCardIndex = 1. It constructs the test and asserts it to be false (the returned value of the branch) What does the tool need to work? In order to function properly, it will need the ability to scan through all source code (including JDK code) to figure out all constraints. Optionally this could be done through the javadoc, but that is not always used to indicate all constraints. It could also do some trial and error, but it pretty much stops if you cannot attach source code to compiled classes. Then it needs some basic knowledge of what the primitive types are, including arrays. And it needs to be able to construct some form of "modification trees". The tool knows that it needs to change a certain variable to a different value in order to get the correct testcase. Hence it will need to list all possible ways to change it, without using reflection obviously. What this tool will not replace is the need to create tailored unit tests that tests all kinds of conditions when a certain method actually works. It is purely to be used to test methods when they invalidate constraints. My questions: Is creating such a tool feasible? Would it ever work, or are there some obvious problems? Would such a tool be useful? Is it even useful to automatically generate these testcases at all? Could it be extended to do even more useful things? Does, by chance, such a project already exist and would I be reinventing the wheel? If not proven useful, but still possible to make such thing, I will still consider it for fun. If it's considered useful, then I might make an open source project for it depending on the time. For people searching more background information about the used Player and Hand classes in my example, please refer to this repository. At the time of writing the PutMonsterOnFieldAction has not been uploaded to the repo yet, but this will be done once I'm done with the unit tests.

• Powershell progress dialogs

  - by Norgean

  Creating nested progress dialogs in Powershell is easy. Let the code speak for itself: for ($i = 1; $i -le 2; $i++) {     Write-Progress -ID 1 -Activity "Outer loop" -Status "Tick $i" -percentComplete ($i / 2*100)     for ($j = 1; $j -le 3; $j++)     {         Write-Progress -ID 2 -Activity "Mid loop" -Status "Tick $j" -percentComplete ($j / 3*100)         for ($k = 1; $k -le 3; $k++)         {             Write-Progress -ID 3 -Activity "Inner loop" -Status "Tick $k" -percentComplete ($k / 3*100)             Sleep(1)         }     } } I.e. some text that explains what we're doing (Activity and Status), and ID numbers. Easy.

• Starting new project with TDD

  - by Carol

  I'm studying TDD and I read that it also helps you to define the design of the app, correct? So I decided to start creating a new project to help me understand it better. I want to create a simple user registration system that will ask for its name, email address, country (will pick one from a list) and phone number. So the question is... I created a new solution in VS 2010, added a new Test project and I just don't know what tests to write! Since it will help me define the design, what tests could I write here? Thanks for any help!

• Starting out with 2D cross-platform game development [closed]

  - by Aran

  I am wanting to challenge myself to build a simple game, that has a character and a randomly generated world. If I get anywhere with it I may perhaps I'll develop it into something more, but the key challenge I want to tackle is cross-platform. I'd also want to have a go at creating engine myself, doing lighting and other bits. Is it worth me using a system like Unity or do I go down a more custom route? The game I would like to make is a 2D game so whether that changes the tools I should use, it would be great to know as well. Supporting mobiles isn't something I am worried about at moment, just looking for Mac and Windows for time being. In future I'll consider other platforms if I get anywhere with the development. So if anyone has any recommendations for a language, engine or system to use would love to her your thoughts.Including pros and cons would be helpful and appreciated and if you can do comparisons that would be awesome as well!

• Are there compatibility issues opening Visual Studio Professional projects in Visual Studio Express, and vice versa? [migrated]

  - by theGreenCabbage

  Disclaimer: I have taken a look at the 50+ StackExchange forums to find the right place, and it seems /Programmers/ is the most suitable Exchange for this. If this is the wrong place to ask this, however, please let me know - I will personally delete the thread. I am in the process of downloading a single license for Visual Studio 2013 for my firm of 2-3 developers. One license is approximately $498.00 USD. As a small firm, our funds are short, but since we will be creating commercial software, we decided we will be needing the features of the Professional edition. At the same time, our decision is to use the Express edition for the rest of the two developers. My question is - will there be compatibility issues between Express projects and Professional projects for Visual Studio?

• Figuring out what object is closer to a certain point?

  - by user1157885

  I'm trying to create fog of war, I have the visual effect created but I'm not sure how to deal with the hiding of other players if they're within the fog of war. So right now the thing I'm trying to do is if another player is hiding behind a wall then not to render that player. I was thinking of doing it by sending a ray in the direction of all the players, and then creating a list of all the obstacles that ray collides with and then trying to figure out if an obstacle was closer than the player in order to predict the distance. But then I realized I'm not really sure how to figure out if the obstacle is infact closer or not because I have to account for all the dimensions, so I'm kind of stuck. First of all is this approach the correct way to go about it and secondly how would I calculate if the obstacle was infact closer taking into account the X Y and Z. Thanks

• Create Adventure Game Scene/Room/Backdrop from Real Photo

  - by Lyuben

  Is there a suitable software or a good tutorial for creating 2D rooms/scenery for adventure games from real photos? Is it possible to achieve good results by using photos, or the hand-drawn style will always be the best choice? Thank you! --- EDIT --- I want to clarify that I'm particularly interested in the art creation process, not on the environment in which to build games. I'm writing the game in Java for Android, but I don't think it matters. Also, I'm not trying to decide if the game will have photo realistic rooms or not - I want to achieve 2d pixelated, old-school style background scenes and I wonder if this can be made from photos, because I cannot draw them myself. For example, can I shoot a scene with my camera and then make it look something like the image in the following link: PIXEL ART FOREST I know that I cannot get the same quality as an absolutely hand-drawn pixel, but I'm looking for some decent technology/tutorial/software to make them somewhat similar.

It'll boot the windows install but then indicate the following error (image included too): A required cd/dvd drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now. Note if the windows installation media is in the CD/DVD drive, you can safely remove it for this step.
