• I am new to game development, what do I need to know? [closed]

  - by farmdve

  I am unsure if this question is a duplicate, I hope it isn't. Are there any resources on the terminology when doing game development? Because, even if you tell me to learn some graphics API, how would I understand the things it does, if I am not well into the terminology(voxel,mesh,polygon,shading). What about the math that is involved in the game(geometry) or the concept of the gravity,collision detection in the game and their respective maths? I am very bad at math, never was good, because I have ADHD, but I won't give up just yet. I look at a game, and I see "textures", but how am I walking on them, how do they take substance so I don't fall off of them? And depth? This is what I need information about, not just a link to a library like SDL(which I have compiled under MinGW and MinGW-W64) and tell me to learn it and the cliché answer "start simple/small". I hope the question(s) are not too vague.

• Xubuntu LightDM shows blank screen half the time

  - by Sman789

  System info: (will be amended if any more info is asked for) My laptop runs Xubuntu 12.10. As it has a Solid State Drive, /tmp, /var/tmp, /var/log and /var/log/apt are set to tmpfs in the /etc/fstab file - in case this makes any difference. Problem My problem is quite simple. Approximately 50% of boot attempts end in the mouse cursor on a black screen (presumably LightDM failing to load), forcing me to restart and try again. I can access the CTRL+ALT+F1 terminal to reboot the machine, but it's very annoying having to boot and reboot two or three times before one works. Oh, and this problem is the same whether I use the Xubuntu or Unity greeter. Thanks for any help you can give.

• How can I imitate interaction and movement in Diablo II?

  - by user422318

  I'm prototyping a simple browser-based game. It's played from a top down perspective on a 2d canvas. You left-click on a point on the map, and your character will begin walking to it. If you click on a different point on the map, then your character will begin walking to the new point. It's similar to Diablo II: http://www.youtube.com/watch?v=EvDKt-To6K0&feature=related How can I best imitate this movement system for a player? Ideas... Track current coords and target coords If target coords are exactly up, left, right, or down, then increment appropriate direction until you get there Implied else: target coords are in a quadrant. To make this movement look natural, character will have to move diagonally. For example, pretend the target is to the northeast. For each game frame, alternate incrementing current coordinates in the north and then east directions.

• How to list Windows shares from terminal?

  - by Zabba

  Here is a simple scenario I have: Windows 7 is sharing a folder (D:\Projects). Full Control permissions have been given to the folder. In Ubuntu 10.10, I can see the Windows shares from Places - Network menu. I can create a folder in the shared Projects folder from Nautilus How do I ls those same folders (displayed in Nautilus) from the terminal? (mount and ls /mnt do not list those Windows shares) Ps. Details on what I am doing: Using Ubuntu as a "headless" VM using VirtualBox. Accessing Ubuntu via PuTTY Ability to give complete access to the Ubuntu VM for the Windows shared folder

• Vanilla forum personal journal tool

  - by user16648

  I am developing a forum for a research project, i am using Vanilla forum (though i am not tied to this yet). Another feature of this site will be a personal journal/diary/blog. Only the user and administrators will have access to the journal. The journal does not need any advanced features. Does anybody have any suggestions on software/script that could easily be integrated with Vanilla forum for this purpose? My first thought was using Wordpress but it is a bit to complex to adminstrate as the site is meant to be simple. And i dont really see how it can be intregrated easily the way i want it.

• Expandable or Auto-Resize TextBox Height

  Recently, I was asked to prepare a Facebook like expandable textbox in a ASP.NET web application, where user can input text and the textbox can be re-sized (more specifically the height) dynamically. I searched for a while and found quite a lot of solutions that use jQuery (example). However, I was looking for something more intrinsic and simple, and finally I found another script on a forum that just use few lines of JavaScript codes: 1. Control declaration: <asp:TextBox ID="txtMsg"...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Data Source Security Part 1

  - by Steve Felts

  I’ve written a couple of articles on how to store data source security credentials using the Oracle wallet.  I plan to write a few articles on the various types of security available to WebLogic Server (WLS) data sources.  There are more options than you might think! There have been several enhancements in this area in WLS 10.3.6.  There are a couple of more enhancements planned for release WLS 12.1.2 that I will include here for completeness.  This isn’t intended as a teaser.  If you call your Oracle support person, you can get them now as minor patches to WLS 10.3.6.   The current security documentation is scattered in a few places, has a few incorrect statements, and is missing a few topics.  It also seems that the knowledge of how to apply some of these features isn’t written down.  The goal of these articles is to talk about WLS data source security in a unified way and to introduce some approaches to using the available features.  Introduction to WebLogic Data Source Security Options By default, you define a single database user and password for a data source.  You can store it in the data source descriptor or make use of the Oracle wallet.  This is a very simple and efficient approach to security.  All of the connections in the connection pool are owned by this user and there is no special processing when a connection is given out.  That is, it’s a homogeneous connection pool and any request can get any connection from a security perspective (there are other aspects like affinity).  Regardless of the end user of the application, all connections in the pool use the same security credentials to access the DBMS.   No additional information is needed when you get a connection because it’s all available from the data source descriptor (or wallet). java.sql.Connection conn =  mydatasource.getConnection(); Note: You can enter the password as a name-value pair in the Properties field (this not permitted for production environments) or you can enter it in the Password field of the data source descriptor. The value in the Password field overrides any password value defined in the Properties passed to the JDBC Driver when creating physical database connections. It is recommended that you use the Password attribute in place of the password property in the properties string because the Password value is encrypted in the configuration file (stored as the password-encrypted attribute in the jdbc-driver-params tag in the module file) and is hidden in the administration console.  The Properties and Password fields are located on the administration console Data Source creation wizard or Data Source Configuration tab. The JDBC API can also be used to programmatically specify a database user name and password as in the following.  java.sql.Connection conn = mydatasource.getConnection(“user”, “password”); According to the JDBC specification, it’s supposed to take a database user and associated password but different vendors implement this differently.  WLS, by default, treats this as an application server user and password.  The pair is authenticated to see if it’s a valid user and that user is used for WLS security permission checks.  By default, the user is then mapped to a database user and password using the data source credential mapper, so this API sort of follows the specification but database credentials are one-step removed from the application code.  More details and the rationale are described later. While the default approach is simple, it does mean that only one database user is doing all of the work.  You can’t figure out who actually did the update and you can’t restrict SQL operations by who is running the operation, at least at the database level.   Any type of per-user logic will need to be in the application code instead of having the database do it.  There are various WLS data source features that can be configured to provide some per-user information about the operations to the database. WebLogic Data Source Security Options This table describes the features available for WebLogic data sources to configure database security credentials and a brief description.  It also captures information about the compatibility of these features with one another. Feature Description Can be used with Can’t be used with User authentication (default) Default getConnection(user, password) behavior – validate the input and use the user/password in the descriptor. Set client identifier Proxy Session, Identity pooling, Use database credentials Use database credentials Instead of using the credential mapper, use the supplied user and password directly. Set client identifier, Proxy session, Identity pooling User authentication, Multi Data Source Set Client Identifier Set a client identifier property associated with the connection (Oracle and DB2 only). Everything Proxy Session Set a light-weight proxy user associated with the connection (Oracle-only). Set client identifier, Use database credentials Identity pooling, User authentication Identity pooling Heterogeneous pool of connections owned by specified users. Set client identifier, Use database credentials Proxy session, User authentication, Labeling, Multi-datasource, Active GridLink Note that all of these features are available with both XA and non-XA drivers. Currently, the Proxy Session and Use Database Credentials options are on the Oracle tab of the Data Source Configuration tab of the administration console (even though the Use Database Credentials feature is not just for Oracle databases – oops).  The rest of the features are on the Identity tab of the Data Source Configuration tab in the administration console (plan on seeing them all in one place in the future). The subsequent articles will describe these features in more detail.  Keep referring back to this table to see the big picture.

• Finish long directory name with tab problem

  - by user1880405

  I have simple problem that I have to long directories which I want to cd into, but I would like to know easy way. mosquito@mosquito-K56CB:~/Downloads$ ls | grep Guns Guns n' Roses - Appetite for Destruction (Japanese Edition) 1987 Guns n' Roses - Use Your Illusion I 1991 Of course I can just copy the name and put it like this: cd "Guns n' Roses - Appetite for Destruction (Japanese Edition) 1987" But why when I write cd Guns then tab, it finishes line into: cd Guns\ n\'\ Roses\ -\ then by my understanding I should just start writing App.. with tab and it should finish whole name, but it does not. And hitting tab twice does not show me anything either. What I am missing here?

• What "version naming convention" do you use?

  - by rjstelling

  Are different version naming conventions suited to different projects? What do you use and why? Personally, I prefer a build number in hexadecimal (e.g 11BCF), this should be incremented very regularly. And then for customers a simple 3 digit version number, i.e. 1.1.3. 1.2.3 (11BCF) <- Build number, should correspond with a revision in source control ^ ^ ^ | | | | | +--- Minor bugs, spelling mistakes, etc. | +----- Minor features, major bug fixes, etc. +------- Major version, UX changes, file format changes, etc.

• No wireless on Ubunto 12.10

  - by Dan Pitkin

  Okay, so I'm pretty new to the whole Ubuntu thing. I installed it yesterday alongside Windows 8, and it installed fine. Then I started it up and tried to connect to my wireless router. It wouldn't give me the option and the only thing that I could find was Edit Connections thing along the top which I didn't understand at all and just ended up confusing me. Can someone give me a simple explanation as to what I have to do? My laptop is a Toshiba Satellite C855-18D. Thanks guys!

• Is an 'if password == XXXXXXX' enough for minimum security?

  - by Prof Plum

  If I create a login for an app that has middle to low security risk (in other words, its not a banking app or anything), is it acceptable for me to verify a password entered by the user by just saying something like: if(enteredPassword == verifiedPassword) SendToRestrictedArea(); else DisplayPasswordUnknownMessage(); It seems to easy to be effective, but I certainly would not mind if that was all that was required. Is a simple check on username/password combo enough? Update: The particular project happens to be a web service, the verification is entirely server side, and it is not open-source. Does the domain change how you would deal with this?

• Stop myself from over-complicating applications

  - by stuartmclark

  Recently I worked on a fairly large project involving C# and MVVM. This application had around 160 projects in the solutions each seprarated into their own layers. As I have been working on this application for almost a year, building it from scratch as part of a team, I am now coming off that project and onto smaller more trivial projects. As I was beginning to develop a small in-house tool I found myself trying to mimic the larger applications structure and layering but in the end I just had a simple application with several DLLs which I know I wouldn't have done if I had not worked on that larger application before. I am just wondering if there are any techniques I can utilise to stop myself from turning a "code-behind" style trivial application into a full blown MVVM application? Or should I continue developing as I am and try to keep the unnecessary fluff out of the project?

• How to move an object along a circumference of another object?

  - by Lumis

  I am so out of math that it hurts, but for some of you this should be a piece of cake. I want to move an object around another along its ages or circumference on a simple circular path. At the moment my game algorithm knows how to move and position a sprite just at the edge of an obstacle and now it waits for the next point to move depending on various conditions. So the mathematical problem here is how to get (aX, aY) and (bX, bY) positions, when I know the Centre (cX, cY), the object position (oX, oY) and the distance required to move (d)

• Are there any free hit counters that don't track users?

  - by David Englund

  Are there any free services that increment a simple hit counter without tracking the users of the site? I would like to know how many visitors there are to my site, excluding bots. I don't need detailed information like unique visitors or where the user is from (in fact, that's exactly what I don't want). I have been researching free hit counters, and it seems that most (all?) of them display advertisements and their terms of service indicate that they can use the data they collect from the client site however they want. Google Analytics also does this and tracks users across sites. The site is static HTML, so an external link or iframe of some sort is easiest for me to implement. I could switch to a Ruby or Node.js back-end, in which case lots of other options open up (like Ruby impressionist and more low-level implementations), but my hosting service is pretty limited. If the answer to my question is simply "no," what are my other options?

• "From the Coal Face" - 1 - What ILDASM can reveal!

  - by TATWORTH

  In a place far, far away, there was a project where the Architect decided on using embedded TSQL in a Dot Net application, rather than use stored procedures. I located ILDASM.EXE (my Framework 3.5 version lives at C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin on my home development PC) and created a shortcut to it in the SendTo folder. Now I could set about doing a simple demonstration to the Architect by taking one of the Dot Net EXE's with the embedded TSQL and sending it to ILDASM.  Since I had written most of the embedded TSQL, it was a matter of seconds before I located the embedded TSQL within the Exe. The TSQL that was supposed to be safely hidden within the EXE was easily located and and copied. (It should also be noted that we could have encrypted the stored procedures on loading them to the database.)

• How to determine which cells in a grid intersect with a given triangle?

  - by Ray Dey

  I'm currently writing a 2D AI simulation, but I'm not completely certain how to check whether the position of an agent is within the field of view of another. Currently, my world partitioning is simple cell-space partitioning (a grid). I want to use a triangle to represent the field of view, but how can I calculate the cells that intersect with the triangle? Similar to this picture: The red areas are the cells I want to calculate, by checking whether the triangle intersects those cells. Thanks in advance. EDIT: Just to add to the confusion (or perhaps even make it easier). Each cell has a min and max vector where the min is the bottom left corner and the max is the top right corner.

• How to divide hex grid evenly among n players?

  - by manabreak

  I'm making a simple hex-based game, and I want the map to be divided evenly among the players. The map is created randomly, and I want the players to have about equal amount of cells, with relatively small areas. For example, if there's four players and 80 cells in the map, each of the players would have about 20 cells (it doesn't have to be spot-on accurate). Also, each player should have no more than four adjacent cells. That is to say, when the map is generated, the biggest "chunks" cannot be more than four cells each. I know this is not always possible for two or three players (as this resembles the "coloring the map" problem), and I'm OK with doing other solutions for those (like creating maps that solve the problem instead). But, for four to eight players, how could I approach this problem? As always, any and all help is appreciated. :)

• 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?

• DIY Touch Screen Mod Makes Regular Gloves Smartphone-friendly

  - by Jason Fitzpatrick

  Smartphone-friendly winter gloves are expensive (and often ugly). Skip shelling out for store-bought gloves when, armed with a needle and thread, you can turn any gloves into smartphone-friendly ones. Over at Popular Science, Taylor Kubota shares the simple trick: 1. Order silver-plated nylon thread (silver conducts electricity). This can be difficult to find in stores, but major online retailers carry it. 2. Pick a pair of gloves to modify. Although leather works, it’s harder to push a needle through. 3. Stitch the figure of a star or other solid shape onto the glove’s index finger with the thread, making sure it will contact both the touchscreen and your skin.
